Item 1.Business
We are a biopharmaceutical company focused on the development, production and commercialization of recombinant therapeutic proteins produced by our proprietary ProCellEx® plant cell-based protein expression system. We are the first and only company to gain FDA approval of a protein produced through plant cell-based expression in suspension. Our unique expression system represents a new method for developing recombinant proteins in an industrial-scale manner.
Our strategic focus is to develop tailored complex recombinant therapeutic proteins primarily produced through ProCellEx while genetically engineering and/or chemically modifying the proteins pre- and/or post-production. We
2
intend such engineering and modifications to provide added clinical benefits by improving the biologic characteristics (e.g., glycosylation, half-life, immunogenicity) of the therapeutic protein.
Our proprietary ProCellEx platform is being used to manufacture our approved and marketed product, Elelyso®, for the treatment of Gaucher disease. We are also developing, via ProCellEx, a pipeline of products. Our clinical development program for pegunigalsidase alfa, or PRX-102, for the potential treatment of Fabry disease is in advanced clinical stages. In addition, we are developing uricase, or PRX-115, for the treatment of refractory gout, PRX-119, a long action DNase I for the treatment of NETs-related diseases, and a number of other product candidates in early and preclinical development.
Product Pipeline
Our ProCellEx Platform
ProCellEx is our proprietary platform used to produce and manufacture recombinant proteins through plant cell-based expressions in suspension. ProCellEx consists of a comprehensive set of proprietary technologies and capabilities, including the use of advanced genetic engineering and plant cell culture technology, enabling us to produce complex, proprietary, and biologically equivalent proteins for a variety of human diseases. Our protein expression system facilitates the creation and selection of high-expressing, genetically-stable cell lines capable of expressing recombinant proteins.
Our technology allows for many unique advantages, including: biologic optimization; an ability to handle complex protein expressions; flexible manufacturing with improvements through efficiencies, enhancements and/or rapid horizontal scale-ups; a simplified production process; elimination of the risk of viral contaminations from mammalian components; and intellectual property advantages.
We developed ProCellEx based on our plant cell culture technology for the development, expression and manufacturing of recombinant proteins, which are the essential foundation of modern biotechnology. We develop new, recombinant therapeutic proteins by using the natural capability of agrobacterium to transfer a DNA fragment into the plant chromosome, allowing the genome of the plant cell to code for specific proteins of interest. The agrobacterium-mediated transformed cells are then able to produce specific proteins, which are extracted and purified and can be used as therapies to treat a variety of diseases.
3
ProCellEx technology can be utilized to express complex therapeutic proteins belonging to different drug classes, such as enzymes, hormones, monoclonal antibodies, cytokines and vaccines. The entire protein expression process, from initial nucleotide cloning to large-scale production of the protein product, occurs under Current Good Manufacturing Practice, or cGMP-, compliant, controlled processes. Our plant cell culture technology uses cells, such as carrot and tobacco (BY-2) cells, which undergo advanced genetic engineering and/or chemical modifications, and are grown on an industrial scale in a disposable, flexible bioreactor system. Our system does not involve mammalian or animal-derived components or transgenic field-grown or whole plants at any point in the production process.
Cell growth, from initiating scale-up steps from a cell-bank through large-scale production takes place in a clean-room environment in flexible, sterile, custom-designed polyethylene bioreactors, and does not require the use of large stainless-steel bioreactors commonly used in mammalian-based systems for recombinant protein production. The ProCellEx reactors are easy to use and maintain, allowing for rapid horizontal scale-up and do not involve the risk of mammalian viral contamination. Our bioreactors are well-suited for plant cell growth using a simple, inexpensive, chemically defined growth medium. The reactors, which are custom-designed and optimized for plant cell cultures, require low initial capital investment and are rapidly scalable at a low cost.
Business Highlights
Elelyso®
Elelyso for the treatment of Gaucher Disease is currently approved and marketed in 23 countries including the United States, Australia, Canada, Israel, Brazil, Russia and Turkey. In June 2012, the European Committee for Medicinal Products for Human Use (CHMP) issued a positive opinion regarding the benefit of Elelyso but did not immediately grant marketing authorization because of the ten-year market exclusivity granted to Vpriv® (Takeda Shire) in August 2010 for the same condition, which was later extended for an additional two years. Elelyso is marketed globally, excluding Brazil, through an exclusive licensing agreement with Pfizer. We maintain the distribution rights to Elelyso in Brazil, where it is currently marketed as BioManguinhos alfataliglicerase, through the Supply and Technology Transfer Agreement we entered into on June 18, 2013, with Fiocruz, an arm of the Brazilian MoH, or the Brazil Agreement. In 2021, we generated $6.4 million from sales of BioManguinhos alfataliglicerase to the Brazilian MoH.

Pegunigalsidase alfa (PRX-102)
Pegunigalsidase alfa, or PRX-102, our lead product candidate, is a late-stage clinical asset in development for the treatment of Fabry disease. We expect PRX-102 to be the primary subject of our development efforts in the short-term. It is our proprietary, investigational, plant cell culture expressed enzyme, and a chemically modified stabilized version of, the recombinant α-Galactosidase-A protein, a lysosomal enzyme, under development for the treatment of Fabry disease. Fabry disease is a serious life-threatening rare genetic disorder. Fabry patients lack α-galactosidase-A resulting in the progressive accumulation of abnormal deposits of a fatty substance called globotriaosylceramide, or Gb3, in blood vessel walls throughout their body. The abnormal storage of Gb3 increases with time and, as a result, Gb3 accumulates, primarily in the blood vessel walls. The ultimate consequences of Gb3 deposition range from episodes of pain and impaired peripheral sensation to end-organ failure, particularly of the kidneys, but also of the heart and the cerebrovascular system. Fabry disease occurs in one person per 40,000 to 60,000 males.
Our phase III clinical program includes three separate studies which are referred to as the BALANCE study, the BRIDGE study and the BRIGHT study. The BRIDGE and BRIGHT studies have been completed, and the last patient in the BALANCE study received the final dose in the study in October 2021. In addition, the phase III clinical program includes two extension studies in which subjects that participated in our phase I/II clinical trials and our phase III clinical trials may enroll and continue to be treated with PRX-102.
On February 7, 2022, an MAA for PRX-102 was submitted to, and subsequently validated by, the EMA. The submission was made after the October 8, 2021 meeting the Company held, together with Chiesi, with the Rapporteur and Co-Rapporteur of the EMA regarding PRX-102. At the meeting on October 8, 2021, we and Chiesi discussed the scope of the then anticipated MAA submission for the European Union, and the Rapporteur and Co-Rapporteur were generally supportive of the planned MAA submission for PRX-102.
On April 28, 2021, we, together with Chiesi, announced the receipt of a CRL from the FDA regarding the BLA originally submitted to the FDA on May 27, 2020 under the FDA’s Accelerated Approval pathway. The BLA was subsequently accepted by the FDA and granted Priority Review designation. The CRL did not report any concerns relating to the potential safety or efficacy of PRX-102 in the submitted data package. In the CRL, the FDA noted that an inspection of our manufacturing facility in Carmiel, Israel, including a subsequent assessment of any related FDA findings, is required before the FDA can approve a resubmitted BLA. Due to travel restrictions, the FDA was unable to conduct the required inspection during the review cycle. The FDA explained in the letter that it will continue to monitor the public health situation as well as travel restrictions, and is actively working to define an approach for scheduling outstanding inspections. With respect to the third-party facility in Europe at which fill and finish processes are performed for PRX-102, due to COVID-19, the FDA reviewed records under Section 704(a)(4) of the U.S. Federal Food, Drug, and Cosmetic Act, or the FFDCA, in lieu of a pre-licensing inspection. In the CRL, the FDA stated that it will communicate remaining issues to the facility in order to seek prompt resolution of any pending items. In addition to the foregoing, in the CRL, the FDA noted that Fabrazyme® (agalsidase beta), a therapy used to treat Fabry patients, was recently converted to full approval and is now an “available therapy,” which must be addressed in the context of any potential resubmission of a BLA for PRX-102.
We and Chiesi participated in a Type A (End of Review) meeting with the FDA on September 9, 2021 to discuss the FDA’s requirements for a BLA resubmission. As part of the meeting minutes provided by the FDA, which included the preliminary comments and meeting discussion, the FDA, in principle, agreed that the clinical data package proposed to the FDA for a BLA resubmission has the potential to support a traditional approval of PRX-102 for the treatment of Fabry disease. The planned data package for the BLA resubmission, given the changed regulatory landscape in the United States, will include the final two-year analyses of the BALANCE study.
We have entered into two exclusive global licensing and supply agreements (ex-U.S. and U.S.) with Chiesi for PRX-102; on October 19, 2017, Protalix Ltd., our wholly-owned subsidiary, entered into an Exclusive License and Supply Agreement with Chiesi, or the Chiesi Ex-US Agreement, pursuant to which Chiesi was granted an exclusive license for all markets outside of the United States to commercialize PRX-102 and on July 23, 2018, Protalix Ltd. entered into an Exclusive License and Supply Agreement with Chiesi, or the Chiesi US Agreement, with respect to the commercialization of PRX-102 in the United States.

Alidornase alfa (PRX-110)
Alidornase alfa is our plant cell-expressed recombinant human DNase I product candidate, administered via inhalation, chemically modified to resist inhibition by actin, thus enabling enzymatic activity in the presence of actin. In vitro studies have shown PRX-110 to have a highly improved catalytic efficiency and affinity to DNA compared to the unmodified DNase I. We completed a phase IIa clinical trial of PRX-110 in Cystic Fibrosis patients in 2018, and PRX-110 was shown to be generally well-tolerated with no serious adverse events reported. Efficacy results demonstrated clinically meaningful lung function improvement following treatment with PRX-110.
PRX-115
PRX-115 is our plant cell-expressed recombinant PEGylated Uricase (urate oxidase) – a chemically modified enzyme under development for the potential treatment of refractory gout. Gout is the most common inflammatory arthritis in the United States, affecting an estimated 9.2 million adults. An estimated approximately 2% of the gout population is considered to have chronic refractory disease. The uricase enzyme converts uric acid to allantoin, which is easily eliminated through urine. However the uricase enzyme does not exist naturally in humans. We use ProCellEx to express an optimized recombinant uricase enzyme under development for the potential treatment of refractory gout which we are designing to have an improved half-life, reduced immunogenicity and potentially longer-term efficacy.
PRX-119
PRX-119 is our plant cell-expressed PEGylated recombinant human DNase I product candidate which we are designing to have an elongated half-life in the circulation for the potential treatment of NETs-related diseases. NETs, Neutrophil extracellular traps, are web-like structures, released by activated neutrophils that trap and kill a variety of microorganisms. NETs are composed of DNA, histones, antimicrobial and pro-inflammatory proteins. Excessive formation or ineffective clearance of NETs can cause different pathological effects. NETs formation has been observed in various autoimmune, inflammatory and fibrotic conditions, diverse forms of thrombosis, cancer and metastasis. According to scientific literature, animal studies have demonstrated that DNase I treatment reduce NETs toxicity. Our proprietary modified DNase I may potentially enable effective treatment of acute and chronic conditions.

Our Marketed Product
Elelyso®
Elelyso (taliglucerase alfa), our first commercial product for the treatment of Gaucher disease, is the first plant cell derived recombinant protein therapeutic approved by major regulatory authorities, including the FDA and the EMA. Elelyso is approved in 23 markets for infusion as an ERT for the long-term treatment of adult and pediatric patients with a confirmed diagnosis of type 1 Gaucher disease. We have licensed to Pfizer the global rights for Elelyso, excluding Brazil. In Brazil, we maintain the distribution rights to taliglucerase alfa, marketed as BioManguinhos alfataliglicerase, through the Brazil Agreement. In 2021, we generated $6.4 million from sales of BioManguinhos alfataliglicerase to the Brazilian MoH.

Gaucher disease, also known as glucocerebrosidase, or GCD, deficiency, is a rare genetic autosomal recessive disorder and one of the most common Lysosomal Storage Disorders in the world. It is one of a group of disorders that affect specific enzymes that normally break down fatty substances for reuse in the cells. If the enzymes are missing or do not work properly, the substances can build up and become toxic. Gaucher disease occurs when a lipid called glucosylceramide accumulates in the cells of the bone marrow, lungs, spleen, liver, and sometimes the brain. Gaucher disease symptoms can include fatigue, anemia, easy bruising and bleeding, severe bone pain and easily broken bones, and distended stomach due to an enlarged spleen and thrombocytopenia. Epidemiology of Gaucher disease varies; recent literature provides that prevalence of Gaucher disease ranges from 0.70 to 1.75 per 100,000 in the general population. In people of Ashkenazi Jewish heritage, estimates of occurrence vary from approximately 1 in 400 to 1 in 850 people. The global market for Gaucher disease is forecasted to be approximately $1.5 billion and $1.6 billion in 2021 and 2022, respectively (Global Data) and to grow at a CAGR of approximately 8.6% from 2020-2027 (Global Data).
The current standard of care for Gaucher disease is ERT, which is a medical treatment where recombinant enzymes are injected into patients to replace the lacking or dysfunctional enzyme. In Gaucher disease, recombinant GCD is infused to replace the mutated or deficient natural GCD enzyme. Elelyso is the only alternative ERT treatment of Gaucher disease to Sanofi Genzyme’s Cerezyme® and VPRIV.
Our Clinical Development Pipeline
Pegunigalsidase alfa (PRX-102)
PRX-102 is our lead product candidate and we expect it to be the primary subject of our development efforts in the short-term. It is our proprietary, investigational, plant cell culture expressed enzyme, and a chemically modified stabilized version of, the recombinant α-Galactosidase-A protein, a lysosomal enzyme, under development for the treatment of Fabry disease. Fabry disease is a serious life-threatening rare genetic disorder. Fabry patients lack α-galactosidase-A resulting in the progressive accumulation of abnormal deposits of Gb3 in blood vessel walls throughout their body. The abnormal storage of Gb3 increases with time. The ultimate consequences of Gb3 deposition range from episodes of pain and impaired peripheral sensation to end-organ failure, particularly of the kidneys, but also of the heart and the cerebrovascular system. Fabry disease occurs in one person per 40,000 to 60,000 males. The global market for Fabry disease is forecasted to be approximately $1.9 billion and $2.1 billion in 2021 and 2022, respectively (Global Data) and to grow at a CAGR of approximately 10% from 2020-2027 (Global Data).
Fabry disease is generally treated with an ERT, Fabrazyme or Replagal. In ERT, the missing α-galactosidase-A is replaced with a recombinant form of the protein via intravenous, or IV infusion once every two weeks. Fabry disease, if left untreated, will progress from a less severe condition to a more serious one. It can have a significant impact on quality of life due to presence of serious, chronic and debilitating complications, including cardiovascular and renal complications, and comorbid conditions such as pain can have a significant impact on the psychological well-being of Fabry patients, which also impacts social functioning. Fabry disease involves substantial reduction in life expectancy. Causes of death are most often cardiovascular disease and, to a lesser extent, cerebrovascular disease and renal disease. The life expectancy of Fabry patients is significantly shorter compared to the general population. Untreated male Fabry patients may experience shortened lifespans to approximately 50 years, and 70 years for untreated women. This represents a 20- and 10-year reduction, respectively.
On February 7, 2022, the PRX-102 MAA was submitted to, and subsequently validated by, the EMA. The submission was made after the October 8, 2021 meeting we held, together with Chiesi, with the Rapporteur and Co-Rapporteur of the EMA regarding PRX-102. At the meeting, we and Chiesi discussed the scope of the anticipated MAA submission for the European Union, and the Rapporteur and Co-Rapporteur were generally supportive of the planned MAA submission. The MAA submission includes a comprehensive set of preclinical, clinical and manufacturing data compiled from our completed and ongoing clinical studies evaluating PRX-102 as a potential treatment for Fabry disease. The submission is supported by the 12–month interim data analysis generated from our phase III BALANCE clinical trial of PRX-102, which was released in June 2021. Data generated from the completed phase III BRIDGE clinical trial, the phase 1/2 clinical trial in naive or untreated patients, and from the extension studies with 1 mg/kg every two weeks were also included in the filing. In addition, the MAA includes data from the completed 12–month switch–over phase III BRIGHT clinical trial of patients treated with the 2 mg/kg every 4 weeks dosage.

The initial BLA submitted on May 27, 2020 included a comprehensive set of preclinical, clinical and manufacturing data compiled from our completed phase I/II clinical trial of PRX-102, including the related extension study succeeding our phase I/II clinical trial, interim clinical data from our phase III BRIDGE switch-over study and safety data from our on-going clinical studies of PRX-102 in patients receiving 1 mg/kg every other week.
On April 28, 2021, we, together with Chiesi, announced the receipt of a CRL from the FDA regarding the BLA. The CRL did not report any concerns relating to the potential safety or efficacy of PRX-102 in the submitted data package. In the CRL, the FDA noted that an inspection of Protalix’s manufacturing facility in Carmiel, Israel, including a subsequent assessment of any related FDA findings, is required before the FDA can approve a resubmitted BLA. Due to travel restrictions, the FDA was unable to conduct the required inspection during the review cycle.

The planned data package for the BLA resubmission, given the changed regulatory landscape in the United States, will include the final two-year analyses of the BALANCE study. We intend to continue to work collaboratively with the FDA resolve the issues noted in the CRL and provide a new, alternative drug to Fabry patients.
Given the changed regulatory landscape in the United States, the planned data package for the PRX-102 BLA resubmission will include the final two-year analyses of the BALANCE study.
In January 2018, the FDA granted Fast Track designation to PRX-102. Fast Track designation is a process designed to facilitate the development and expedite the review of drugs and vaccines for serious conditions that fill an unmet medical need.
In December 2017, the European Commission granted Orphan Drug Designation for PRX-102 for the treatment of Fabry disease. Orphan Drug Designation for PRX-102 qualifies Chiesi for access to a centralized marketing authorization procedure, including applications for inspections and for protocol assistance. If the orphan drug designation is maintained at the time PRX-102 is approved for marketing in the European Union, if at all, we expect that PRX-102 will benefit from 10 years of market exclusivity within the European Union. The market exclusivity will not have any effect on Fabry disease treatments already approved at that time.
Key Trials and Design
Our clinical development program is designed to show that PRX-102 has a potential clinical benefit in all adult Fabry patient populations when compared to currently marketed Fabry disease enzymes, Fabrazyme and Replagal. In preclinical studies, PRX-102 showed enhanced activity in Fabry disease target organs, reduction of the accumulated substrate, significantly longer half-life due to higher enzyme stability, and reduced immunogenicity, which together can potentially lead to improved efficacy through increased substrate clearance and significantly lower formation of antibodies. Providing a meaningful improvement in the health and quality of life for Fabry patients being treated with PRX-102 represents a significant potential market opportunity.
Our phase III clinical program of PRX-102 for the treatment of Fabry disease includes three individual studies; the BALANCE study, the BRIDGE study and the BRIGHT study. The BRIDGE and BRIGHT studies have been completed, and the last patient in the BALANCE study received the final dose in the study in October 2021. In 2015, we completed a phase I/II clinical trial of PRX-102. In the phase III clinical program, we are studying two potential dosing regimens for PRX-102; 1 mg/kg every two weeks, with the potential for improved efficacy and safety offering a potential alternative
9
to existing enzyme replacement therapies, and 2 mg/kg every four weeks, which has the potential to lower treatment burden versus existing treatments and potentially provide a better quality of life for a subset of Fabry patients.
Patients that completed the BALANCE, BRIDGE and BRIGHT studies, and the extension of the phase I/II study, were offered the opportunity to continue PRX-102 treatment in one of two long-term open-label extension studies. Currently, 126 subjects that participated in the our PRX-102 clinical program have opted, with the advice of the treating physician, to continue PRX-102 treatment in one of our long-term extension studies; 10 subjects that completed an extension study from the phase I/II clinical trial, 18 subjects that completed the BRIDGE study; 69 subjects that completed the BALANCE study; and 29 subjects that completed the BRIGHT study. Of the 29 subjects that completed the BRIGHT study that are enrolled in a long-term extension study, 27 of them are being treated with 2 mg/kg of PRX-102 every 4 weeks and two are being treated with 1 mg/kg every two weeks.
In February 2020, we, together with Chiesi, announced an agreement with the FDA for the Initial Pediatric Study Plan (iPSP) for PRX-102. The joint announcement was made after completion of discussions with the FDA and receipt of confirmation from the FDA in an official “Agreement Letter” which outlines an agreed-upon approach to evaluate the safety and efficacy of PRX-102 in pediatric Fabry patients in a clinical trial to be performed by Chiesi with our collaborative efforts.
Phase III BALANCE Study
The BALANCE study is a 24-month, randomized, double blind, active control study of PRX-102 in Fabry patients with impaired renal function. A total of 78 patients were enrolled in the trial which was designed to evaluate the safety and efficacy of PRX-102 compared to agalsidase beta (Fabrazyme) on renal function in Fabry patients with progressing kidney disease previously treated with Fabrazyme infused once every two weeks. The last patient in the study received the final dose in October 2021. Patients previously treated with Fabrazyme for approximately one year and on a stable dose for at least six months were screened and then randomized on a 2:1 ratio to 1 mg/kg of PRX-102 or 1 mg/kg of Fabrazyme. Randomization is being stratified by urinary protein to creatinine ratio (UPCR) of ≥ 1 g/g by spot urine sample. The study was designed such that no more than 50% of the patients enrolled in the study would be female. Approximately 40% of the enrolled patients were female.
The primary endpoint of the BALANCE study is the comparison in the annualized rate of decline of estimated Glomerular Filtration Rate, or eGFR, slope between Fabrazyme and PRX-102. eGFR is considered a reliable and accepted test to measure kidney function and stage of kidney disease. Additional parameters being evaluated include:
10
cardiac assessment, Lyso-Gb3 (a biomarker for monitoring Fabry patients during therapy), pain, quality of life, immunogenicity, Fabry Clinical Events and pharmacokinetic and other parameters.
In June 2021, we, together with Chiesi, announced topline results from an interim analysis of the BALANCE study. The primary endpoint of the interim analysis is the comparison of mean annualized changes (slope) of the eGFR(CKD-EPI) after completion of at least 12 months of treatment between the two treatment arms (Fabrazyme and PRX-102). The interim efficacy analysis was conducted on two pre-defined analysis sets: Intention to Treat (ITT), consisting of all randomized patients who received at least one dose (77 patients), considered as the primary analysis for this interim review; and the Per Protocol (PP), consisting of all patients who completed at least 12 months of treatment with no major protocol violations (74 patients). The patient population (ITT analysis set) of the study is comprised of 47 males (61%) and 30 females (39%) with a mean age of 44.3 years.
The initial top-line results show that the lower boundary of the confidence interval for the mean difference between the two treatments was below the non-inferiority margin pre-specified for this interim analysis in the ITT analysis set and above such limit in the PP analysis set. At the time of this analysis, two patients discontinued participation due to treatment emergent adverse events (TEAEs). Of these two patients, one discontinued participation due to a related adverse event. No deaths were registered. Overall, safety data appears favorable and consistent with what was observed in previous clinical studies with PRX-102. We expect top-line results from the BALANCE study to be released in the second quarter of 2022 and final results to be released in the second half of 2022.
The planned data package for the BLA resubmission, given the changed regulatory landscape in the United States, will include the final two-year analyses of the BALANCE study.
Phase III BRIDGE Study
The BRIDGE study was a 12-month open-label, single arm switch-over study evaluating the safety and efficacy of pegunigalsidase alfa, 1 mg/kg infused every two weeks, in up to 22 Fabry patients previously treated with Replagal (agalsidase alfa; marketed by Takeda Pharmaceutical Company Limited (acquired Shire Plc)) for at least two years and on a stable dose for at least six months. The trial was completed in December 2019. Patients were screened and evaluated over three months while continuing Replagal treatment.
Final results of the data generated in the BRIDGE study showed substantial improvement in renal function as measured by mean annualized eGFR slope in both male and female patients. Twenty of 22 patients completed the 12-month treatment duration. Eighteen of the patients who completed the study opted to roll over to a long-term extension study and continue to be treated with PRX-102. In the study, the mean annualized eGFR slope of the study participants improved from -5.90 mL/min/1.73m2/year while on agalsidase alfa to -1.19 mL/min/1.73m2/year on PRX-102 in all patients. Male patients improved from -6.36 mL/min/1.73m2/year to -1.73 mL/min/1.73m2/year and female patients improved from -5.03 mL/min/1.73m2/year to -0.21 mL/min/1.73m2/year. Following the switch to PRX-102, there was a decrease in patients with progressing or fast progressing kidney disease which is consistent with the therapeutic goals for Fabry disease, as identified by Christoph Wanner, et. al., in 2019, and most patients achieved a stable status post-switch.
PRX-102 was well-tolerated in the BRIDGE study, with all adverse events being transient in nature without sequelae. Of the 22 patients enrolled in the BRIDGE study, the majority of treatment emergent adverse events were mild or moderate in severity, with two patients (9.1%) withdrawing from the therapy due to hypersensitivity reaction that was resolved. The most common moderate treatment emergent adverse events were nasopharyngitis, headache and dyspnea.
An immunogenicity assessment indicated that four out of 20 patients (20%) developed persistent antidrug antibodies over the course of the study, of which two had neutralizing activity.
Baseline characteristics of the 20 patients that completed the study, ranging from ages 28 to 60 years, were as follows: mean eGFR 75.87 mL/min/1.73m2 in males, and 86.14 mL/min/1.73m2 in females and plasma lyso-Gb3 were 51.81 nM and 13.81 nM in males and females, respectively. While lyso-Gb3 levels remain slightly high, particularly within the male cohort, continuous reduction in lyso-Gb3 levels was observed of 19.55 nM (32.35%) in males and 4.57 nM (29.81%) in females.
11
Data from the interim analysis of the BRIDGE study, which were first announced in February 2020, were used to support the PRX-102 BLA filing with the FDA, and we anticipate that the final analysis will be used to support the planned MAA submission to the EMA and the BLA resubmission.
Phase III BRIGHT Study
The BRIGHT study was a multicenter, multinational open-label, switch-over study designed to evaluate the safety, efficacy and pharmacokinetics of treatment with 2 mg/kg of PRX-102 administered every four weeks for 52 weeks (a total of 14 infusions). The trial, which was completed in June 2020, enrolled 30 adult patients (24 males and 6 females) with mean (SD) age of 40.5 (11.3) years, ranging from 19 to 58 years previously treated with a commercially available ERT (Fabrazyme or Replagal), for at least three years and on a stable dose administered every two weeks. To determine eligibility for participation in the study, candidates were screened to identify and select Fabry patients with clinically stable kidney disease. The most common Fabry disease symptoms at baseline were acroparesthesia, heat intolerance, angiokeratomas and hypohydrosis. Patients who matched the criteria were enrolled in the study and switched from their current treatment of IV infusions every 2 weeks to 2 mg/kg of PRX-102 every 4 weeks for 12 months. Patients participating in the study were evaluated, among other disease parameters, to determine if their kidney disease had not further deteriorated while being treated with the 4-week dosing regimen as measured by eGFR and Lyso-Gb3, as well as other parameters. In addition, participating patients were evaluated to assess the safety and tolerability of PRX-102.
We announced final results from the BRIGHT study in March 2022. The results indicate that 2 mg/kg of PRX-102 administered by intravenous infusion every four weeks was well tolerated, and Fabry disease assessed by eGFR slope and plasma lyso-Gb3 was stable throughout PRX-102 treatment in adult Fabry patients. None of the patients without anti-drug antibodies, or ADAs, at screening developed treatment-induced ADAs following the switch to PRX-102 treatment.
All 30 patients received at least one dose of pegunigalsidase alfa, and 29 patients completed the one-year study. Of these 29 patients, 28 received the intended regimen of 2 mg/kg every 4 weeks throughout the entire study, while one patient was switched to 1 mg/kg pegunigalsidase alfa every two weeks per protocol at the 11th infusion. One patient withdrew from the study after the first infusion due to a traffic accident.
First infusions of PRX-102 were administered under controlled conditions at the investigation site. Based on the protocol-specified criteria, patients were able to receive their PRX-102 infusions at a home care setup once the Investigator and Sponsor Medical Monitor agreed that it was safe to do so. Safety and efficacy exploratory endpoints were assessed throughout the 52-week study.
Overall, 33 of 183 total treatment-emergent adverse events (TEAEs) reported in nine (30.0%) of the patients were considered treatment related; all were mild or moderate in severity and the majority were resolved at the end of the study. There were no serious or severe treatment-related TEAEs and no TEAEs lead to death or study withdrawal. Of the treatment-related TEAEs, 27 were infusion-related reactions (IRRs) and the remainder were single events of diarrhea, erythema, fatigue, influenza-like illness, increases urine protein/creatinine ratio, and urine positive for white blood cells. The 27 IRRs were reported in five (16.7%) patients, all male. All IRRs occurred during the infusion or within two hours post-infusion; no events were recorded between two and 24 hours post-infusion.
Study outcome measures show that plasma lyso-Gb3 concentrations remained stable during the study with a mean change (±SE) of 3.01 nM (0.94) from baseline (19.36 nM ±3.35) to Week 52 (22.23 ±3.60 nM). Mean absolute eGFR values were stable during the 52-week treatment period, with a mean change from baseline of -1.27 mL/min/1.73 m2 (1.39). Mean (SE) eGFR slope, at the end of the study, for the overall population, was -2.92 (1.05) mL/min/1.73m2/year indicating stability.
The study suggests that Fabry patients who are currently receiving ERT every 2 weeks may be successfully transitioned to PRX-102 2 mg/kg every 4 weeks as an effective and tolerable alternative treatment option. Additional long term data is being collected as part of the ongoing long term extension study (NCT03614234) of the 2 mg/kg PRX-102 every 4 weeks dose.
12
Following a survey of participants using the Quality of Life EQ-5D-5L questionnaire, responses indicate that patient perception of their own health remained high and stable throughout the 52-week study duration, with overall health mean (SE) scores of 78.3 (3.1) and 82.1 (2.9) at baseline and Week 52, respectively, in a 0 to 100 scale. Using the short-form Brief Pain Inventory, or, questionnaire, approximately 75% of study participants had an improvement or no change in average pain severity at Week 52 (compared to baseline). The short-form BPI interference items also remained stable during the study. Pain-related results indicate that there was no increase and/or relapse in pain. No Fabry clinical events were reported during the study.
COVID-19 Impact on PRX-102 Clinical Trials
To date, the COVID-19 pandemic has had a minimal effect on the performance of the phase III clinical trials of PRX-102 as many of the patients were already treated in home care settings. We were able to complete two of the trials and the last patient in the BALANCE study received the final dose in the study in October 2021. In a minimal amount of cases, patients that completed a trial were not able to be transferred into an extension study due to the pandemic restrictions, and, accordingly, the main trial was prolonged for the patients to permit the continuation of treatment.
Phase I/II Study
Our phase I/II clinical trial of PRX-102, which we completed in 2015, was a worldwide, multi-center, open-label, dose ranging study designed to evaluate the safety, tolerability, pharmacokinetics, immunogenicity and efficacy parameters of PRX-102 in adult Fabry patients. Sixteen adult, naïve Fabry patients (9 male and 7 female) completed the trial, each in one of three dosing groups, 0.2 mg/kg, 1 mg/kg and 2 mg/kg. Each patient received IV infusions of PRX-102 every two weeks for 12 weeks, with efficacy follow-up after six-month and twelve-month periods. A majority of the patients who completed the trial opted to continue receiving PRX-102 in an open-label, 60-month extension study under which all patients were switched to receive 1 mg/kg of the drug, the selected dose for our BALANCE and BRIDGE studies of PRX-102.
The adult symptomatic, ERT-naïve Fabry disease patients enrolled in the phase I/II study were evaluated for Gb3 levels in kidney biopsies and for plasma Lyso-Gb3 concentration by the quantitative BLISS methodology. Biopsies were available from 14 patients. The outcome of ≥ 50% reduction in the average number of Gb3 inclusions per kidney PTC from baseline to Month 6 was demonstrated in 11 of 14 (78.6%) of the patients treated with PRX-102. The overall results demonstrate that PRX-102 reaches the affected tissue and reduces kidney Gb3 inclusions burden and Lyso-Gb3 in the circulation. A high correlation was found between the two Fabry disease biomarkers, reduction of kidney Gb3 inclusions and the reduction of plasma Lyso-Gb3 over six months of treatment.
Data was recorded at 24 months from 11 patients who completed 12 months of the long-term open-label extension trial that succeeded the phase I/II study. Patients who did not continue in the extension trial included: female patients who became or planned to become pregnant and therefore were unable to continue in accordance with the study protocol; and patients who relocated to a location where treatment was not available under the clinical study.
Results show that Lyso-Gb3 levels decreased approximately 90% from baseline. Renal function remained stable with mean eGFR levels of 108.02 and 107.20 at baseline and 24 months, respectively, with a modest annual eGFR slope of -2.1. An improvement across all the gastrointestinal symptoms evaluated, including severity and frequency of abdominal pain and frequency of diarrhea, was noted. Cardiac parameters, including LVM, LVMI and EF, remained stable with no cardiac fibrosis development detected. In conclusion, an improvement of over 40% in disease severity was shown as measured by the Mainz Severity Score Index, or MSSI, a score compiling the different elements of the disease severity including neurological, renal and cardiovascular parameters. In addition, an improvement was noted in each of the individual parameters of the MSSI.
The majority of adverse events were mild-to-moderate in severity, and transient in nature. During the first 12 months of treatment, only three of 16 patients (less than 19%) formed ADAs of which two of these patients (less than 13%) had neutralizing antibodies. Importantly, however, the ADAs turned negative for all three of these patients following 12 months of treatment. The ADA positivity effect had no observed impact on the safety, efficacy or continuous biomarker reduction of PRX-102.

Alidornase Alfa (PRX-110)
Alidornase alfa is our chemically-modified plant cell expressed recombinant human DNase I, administered via inhalation. Recombinant human DNase I enzymatically cleaves DNA but its activity is inhibited by actin, which is present in the blood and other target organs. PRX-110 is designed to be less susceptible to actin inhibition and have higher affinity to DNA, thus enhancing enzymatic activity. In-vitro studies have shown PRX-110 to have a highly improved catalytic efficiency and affinity to DNA, compared to dornase alfa (Pulmozyme®, currently the only commercially available DNase therapy), even more so in the presence of actin. In February 2021, we entered into an exclusive worldwide license agreement with SarcoMed with respect to PRX-110 for use in the treatment of any human respiratory disease or condition including, but not limited to, sarcoidosis, pulmonary fibrosis, and other related diseases via inhaled delivery. The license agreement expired during the three months ended September 30, 2021. We are continuing to evaluate potential strategic marketing partnerships and collaboration programs with biotechnology and pharmaceutical companies for this product candidate for various respiratory indications.
We completed a phase I clinical trial of PRX-110 with 18 healthy volunteers, in whom alidornase alfa was found to be well tolerated.
In July 2016, we commenced a phase IIa clinical trial of PRX-110 for the treatment of Cystic Fibrosis, and we released the final results of the study in April 2017. Sixteen patients were enrolled in the study, all of whom completed the study. The phase IIa clinical trial was a 28-day switchover study to evaluate the safety and efficacy of PRX-110 in Cystic Fibrosis patients previously treated with Pulmozyme (dornase alfa). Participation in the trial was preceded by a two-week washout period from Pulmozyme before treatment with PRX-110 via inhalation.
Primary efficacy results from the phase IIa study demonstrated clinically meaningful lung function improvement following treatment with PRX-110, as demonstrated by a mean absolute improvement in the percent predicted forced expiratory volume in one second (ppFEV1) of 3.4 points from baseline. Moreover, a mean absolute increase in ppFEV1 of 2.8 points was also observed in patients participating in the study when compared to measurements taken from patients at initiation, before the switch from Pulmozyme to PRX-110.
PRX-115
PRX-115 is our plant cell-expressed recombinant PEGylated uricase (urate oxidase) – a chemically modified enzyme under development for the potential treatment of refractory gout. Gout is the most common inflammatory arthritis in the United States, affecting an estimated 9.2 million adults. Gout is caused by factors that elevate serum uric acid, or sUA, levels, which may include diet or genetic predisposition and environmental factors leading to hyperuricemia and tissue deposition of monosodium urate crystals, tophi, in joints and soft tissues, causing acute and chronic inflammation, and is characterized by recurrent flares. Gout flares lead to substantial morbidity by causing severe pain, reduced quality of life, decreased physical function, increased healthcare costs, and lost economic productivity. Furthermore, gout is strongly associated with metabolic syndrome, and may contribute to myocardial infarction, type 2 diabetes mellitus, chronic kidney disease, or CKD, and premature mortality.
Currently available urate-lowering therapies, or ULTs, can be effective in treating gout. Refractory gout patients are those whom, despite treatment with existing ULTs, have high flare frequency, consistent tophi, and the inability to maintain therapeutic goals of urate levels. An estimated approximately 2% of the gout population is considered to have chronic refractory disease and are in need of other therapeutic options. One option may be a therapeutic use of the uricase enzyme which converts uric acid to allantoin, which is easily eliminated through urine. The uricase enzyme does not exist naturally in humans. To date, two variants of recombinant uricases are approved for marketing: (i) Krystexxa® for treatment of chronic gout refractory to conventional therapy (no longer approved in the European Union) and (ii) Elitek®, indicated for the treatment of tumor lysis syndrome but not gout. Both have a black box warning for anaphylaxis, induce strong immunogenic reactions and have other major side-effects. We use ProCellEx to express an optimized recombinant uricase enzyme under development for the potential treatment of refractory gout which we are designing to have an improved half-life, reduced immunogenicity and potentially longer term efficacy.

PRX-119
PRX-119 is our plant cell-expressed PEGylated recombinant human DNase I product candidate being designed to elongate half-life in the circulation for NETs-related diseases. NETs, Neutrophil extracellular traps, are web-like structures, released by activated neutrophils that trap and kill a variety of microorganisms. NETs are composed of DNA, histones, antimicrobial and pro-inflammatory proteins. Excessive formation or ineffective clearance of NETs can cause different pathological effects. NETs formation has been observed in various autoimmune, inflammatory and fibrotic conditions, diverse forms of thrombosis, cancer and metastasis. According to scientific literature, animal studies have demonstrated that DNase treatment reduces NETs toxicity. Our proprietary modified DNase I design for long and customized systemically circulating in the bloodstream, may potentially enable effective treatment of acute and chronic conditions.

We are aware of U.S. patents, and corresponding international counterparts of such patents, owned by third parties that contain claims covering methods of producing glucocerebrosidase. We do not believe that, if any claim of infringement were to be asserted against us based upon such patents, taliglucerase alfa would be found to infringe any valid claim under such patents. However, there can be no assurance that a court would find in our favor or that, if we choose or are required to seek a license to any one or more of such patents, a license would be available to us on acceptable terms or at all.
In April 2005, Protalix Ltd. entered into a license agreement with Icon Genetics AG, or Icon, pursuant to which we received an exclusive worldwide license to develop, test, use and commercialize Icon’s technology to express certain proteins in our ProCellEx protein expression system. We are also entitled to a non-exclusive worldwide license to make and have made other proteins expressed by using Icon’s technology in our technology. As consideration for the license, we are obligated to make royalty payments equal to varying low, single-digit percentages of net sales of products by us, our affiliates, or any sublicensees under the agreement. In addition, we are obligated to make milestone payments equal to $350,000, in the aggregate, for each product developed under the license, upon the achievement of certain milestones.
Our license agreement with Icon remains in effect until the earlier of the expiration of the last patent under the agreement or, if all of the patents under the agreement expire, 20 years after the first commercial sale of any product under the agreement. Icon may terminate the agreement upon written notice to us that we are in material breach of our obligations under the agreement and we are unable to remedy such material breach within 30 days after we receive such notice. Further, Icon may terminate the agreement in connection with certain events relating to a wind up or bankruptcy, if we make a general assignment for the benefit of our creditors, or if we cease to conduct operations for a certain period. Icon may also terminate the exclusivity granted to us by written notice if we fail to reach certain milestones within a designated period of time. Notwithstanding the termination date of the agreement, our obligation to pay royalties to Icon under the agreement may expire prior to the termination of the agreement, subject to certain conditions.
Competition
The biotechnology and pharmaceutical industries are characterized by rapidly evolving technology and significant competition. Competition from numerous existing companies and others entering the fields in which we operate is intense and expected to increase. Most of these companies have substantially greater research and development, manufacturing, marketing, financial, technological personnel and managerial resources than we do. In addition, many specialized biotechnology companies have formed collaborations with large, established companies to support research, development and commercialization of products that may be competitive with our current and future product candidates and technologies. Acquisitions of competing companies by large pharmaceutical or biotechnology companies could further enhance such competitors’ financial, marketing and other resources. Academic institutions, governmental agencies and other public and private research organizations are also conducting research activities and seeking patent protection and may commercialize competitive products or technologies on their own through collaborations with pharmaceutical and biotechnology companies.
17
With respect to Gaucher disease, we face competition from two ERTs, Sanofi Genzyme’s Cerezyme and Takeda’s (Shire) Vpriv. In addition, Actelion markets a small molecule drug for the treatment of mild to moderate Type 1 Gaucher disease (Zavesca or miglustat), an oral treatment approved by the FDA only for patients for whom ERT is not a therapeutic option. In addition, Sanofi Genzyme markets a small molecule oral drug, Cerdelga®, approved for Gaucher patients with certain CYP2D6 metabolizer status.
With respect to Fabry disease, we face competition from Sanofi Genzyme (Fabrazyme), Takeda Shire (Replagal) and Amicus (Galafold®). In addition, we are aware of other late clinical stage, early clinical stage and experimental drugs which are being developed for the treatment of Fabry disease by other companies. For example, eleva GmbH (formerly, Greenovation Biotech GmbH), or eleva, is developing an ERT for Fabry disease which has completed a phase I clinical trial.
With respect to refractory gout, we face competition from Horizon Therapeutics Public Limited Company (Krsytexxa), which is indicated for treatment of chronic gout in adult patients refractory to conventional therapy. In addition, we are aware of other clinical stage, early clinical stage and experimental refractory or chronic gout treatments. For example, we are aware of a product candidate that is the subject of a phase III clinical trial for chronic refractory gout and another product candidate that is the subject of a phase II clinical trial for hyperuricemia in gout patients with advanced CKD.
We also face potential competition to our ProCellEx system from companies that are developing other platforms for the expression of recombinant therapeutic pharmaceuticals. We are aware of companies that are developing alternative technologies to develop and produce therapeutic proteins in anticipation of the expiration of certain patent claims covering marketed proteins. A number of companies have developed or are developing alternative expression technologies. Examples include Crucell N.V. (acquired by Johnson & Johnson) has an expression system based on human-cell technology, Dyadic International Inc.’s expression system based on a fungus, Pfenex Inc.’s (acquired by Ligand Pharmaceuticals Incorporated) bacteria-based expression system, and others. Companies developing alternate plant-based technologies include iBio, Inc., Medicago, Inc., and eleva. Unlike ProCellEx, these alternate technologies are not cell-based. These companies base their product development on transgenic plants or whole plants.
Agreements and Partnerships
Elelyso – Pfizer
We have licensed to Pfizer the global rights to Elelyso in all markets, excluding Brazil, pursuant to an Amended and Restated Exclusive License and Supply Agreement, or the Amended Pfizer Agreement, which we entered into with Pfizer in October 2015 to amend and restate our initial Exclusive License and Supply Agreement with Pfizer, or the Pfizer Agreement. Pursuant to the Amended Pfizer Agreement, Pfizer retains 100% of revenue and reimburses 100% of direct costs. For the first 10-year period after the execution of the Amended Pfizer Agreement, we have agreed to sell drug substance to Pfizer for the production of Elelyso, subject to certain terms and conditions, and Pfizer maintains the right to extend the supply period for up to two additional 30-month periods, subject to certain terms and conditions. In a subsequent amendment, we agreed that after the completion of the first 10-year supply period, the supply term would automatically extend for a five-year period. Any failure to comply with our supply commitments may subject us to substantial financial penalties. The Amended Pfizer Agreement includes customary provisions regarding cooperation for regulatory matters, patent enforcement, termination, indemnification and insurance requirements. We maintain distribution rights to taliglucerase alfa in Brazil.
Elelyso – Fundação Oswaldo Cruz (Fiocruz)
Elelyso, marketed as BioManguinhos alfataliglicerase in Brazil, is commercialized in Brazil through the Brazil Agreement with Fiocruz, which became effective in January 2014. Gaucher patients in Brazil are entitled to receive ERT paid for by the Brazilian MoH. The Brazilian MoH clinical treatment guidelines state that BioManguinhos alfataliglicerase is the therapy of choice for newly diagnosed patients. BioManguinhos alfataliglicerase is currently estimated to be used by approximately 25% of Gaucher patients in Brazil.
The Brazil Agreement provides for a staged technology transfer which is intended to transfer to Fiocruz the capacity and skills required for the Brazilian government to construct its own manufacturing facility, at its sole expense, and to
18
produce a sustainable, high-quality, and cost-effective supply of BioManguinhos alfataliglicerase. Fiocruz has not satisfied certain purchase commitments under the Brazil Agreement. Accordingly, we and Fiocruz discuss on a continuous basis, potential steps to maximize sales of BioManguinhos alfataliglicerase sales to the Brazilian MoH.
PRX-102 – Chiesi Farmaceutici
We have entered into two exclusive global licensing and supply agreements for PRX-102 for the treatment of Fabry disease with Chiesi. The agreements have significant revenue potential for Protalix. Under the agreements, Protalix Ltd. has received $50.0 million in upfront payments and was entitled to development cost reimbursements of up to $45 million, up to more than $1.0 billion in potential milestone payments and tiered royalties of 15% - 35% (ex-US) and 15% - 40% (US).
On October 19, 2017, Protalix Ltd. and Chiesi entered into the Chiesi Ex-US Agreement pursuant to which Chiesi was granted an exclusive license for all markets outside of the United States to commercialize PRX-102. Under the Chiesi Ex-US Agreement, Chiesi made an upfront payment to Protalix Ltd. of $25.0 million in connection with the execution of the agreement, and Protalix Ltd. was entitled to additional payments of up to $25.0 million in development costs in the aggregate, capped at $10.0 million per year. Protalix Ltd. is also eligible to receive additional payments of up to a maximum of $320.0 million in regulatory and commercial milestone payments. Protalix Ltd. agreed to manufacture all of the PRX-102 needed for all purposes under the agreement, subject to certain exceptions, and Chiesi will purchase PRX-102 from Protalix Ltd., subject to certain terms and conditions. Chiesi is required to make tiered payments of 15% to 35% of its net sales, depending on the amount of annual sales, as consideration for the supply of PRX-102.
On July 23, 2018, Protalix Ltd. entered into the Chiesi US Agreement with respect to the development and commercialization of PRX-102 in the United States. Protalix Ltd. received an upfront, non-refundable, non-creditable payment of $25.0 million from Chiesi and was entitled to additional payments of up to a maximum of $20.0 million to cover development costs for PRX-102, subject to a maximum of $7.5 million per year. Protalix Ltd. is also eligible to receive additional payments of up to a maximum of $760.0 million, in the aggregate, in regulatory and commercial milestone payments. Chiesi will also make tiered payments of 15% to 40% of its net sales under the Chiesi US Agreement to Protalix Ltd., depending on the amount of annual sales, subject to certain terms and conditions, as consideration for product supply.
On May 13, 2021, we signed a binding term sheet with Chiesi pursuant to which we and Chiesi amended the Chiesi Agreements in order to provide our company with near-term capital. Chiesi agreed to make a $10.0 million payment to us before the end of the second quarter of 2021 in exchange for a $25.0 million reduction in a longer term regulatory milestone payment provided in the Chiesi EX-US Agreement. All other regulatory and commercial milestone payments remain unchanged. We Company received the payment in June 2021. We also agreed to negotiate certain manufacturing related matters.
Manufacturing
We use our current manufacturing facility in Carmiel, Israel, which has approximately 14,700 sq/ft of clean rooms built according to industry standards, to manufacture drug substance for Elelyso, pegunigalsidase alfa and other recombinant proteins for commercial use and phase III clinical trials. We maintain an approximately 3,400 sq/ft pilot plant for protein development and to manufacture supplies for clinical trials (phase I and phase II). Elelyso, pegunigalsidase alfa and our other drug product candidates must be manufactured in a sterile environment and in compliance with cGMPs set by the FDA and other relevant foreign regulatory authorities. We are currently producing PRX-102 drug substance for our phase III and other clinical trials, as well as the manufacture of the Elelyso we need in the near future, including the Elelyso to be purchased by Pfizer under the Amended Pfizer Agreement. In addition, we intend to use our manufacturing space to produce all of the drug substance needed in connection with the clinical trials for our product candidates.
In 2017, the FDA approved the supplemental New Drug Application, sNDA, we submitted to allow us to convert our manufacturing facility from a single dedicated product facility to a multi-product facility. This conversion allows us to realize potentially significant operational savings. Our facility’s current capacity can serve all of our current and expected commercial and clinical needs, and we believe it will be sufficient to serve our production needs for the anticipated commercialization of pegunigalsidase alfa.
19
Our manufacturing facilities have undergone successful inspections by the FDA, the Irish Medicines Board (under the EMA’s centralized marketing authorization procedure), ANVISA, the Israeli Ministry of Health, the Turkish Ministry of Health, the Australian TGA and Health Canada.
Our current facility in Israel has been granted “Approved Enterprise” status, and we have elected to participate in the alternative benefits program. Our facility is located in a top priority location, or “Zone A,” location, and, therefore, our income from the Approved Enterprise will be tax exempt in Israel for a 10-year period, commencing with the year in which we first generate taxable income from the relevant Approved Enterprise and after we use our net operating loss carryforwards, or NOLs. We expect to be entitled to similar tax benefits for a number of years thereafter. To remain eligible for these tax benefits, we must continue to meet certain conditions, and if we increase our activities outside of Israel, for example, by future acquisitions, such increased activities generally may not be eligible for inclusion in Israeli tax benefit programs. In addition, our technology is subject to certain restrictions with respect to the transfer of technology and manufacturing rights.
Raw Materials and Suppliers
We believe that the raw materials that we require throughout the manufacturing process of Elelyso and our other current and potential drug product candidates are widely available from numerous suppliers and are generally considered to be generic industrial biological supplies. We rely on a single, approved supplier for certain materials relating to the current expression of our proprietary biotherapeutic proteins through ProCellEx. We have identified additional suppliers for most of the materials required for the production of our product candidates.
Development and regulatory approval of our pharmaceutical products are dependent upon our ability to procure active ingredients and certain packaging materials from sources approved by the FDA and other regulatory authorities. The FDA and other regulatory approval processes require manufacturers to specify their proposed suppliers of active ingredients and certain packaging materials in their applications. From time to time, we intend to continue to identify alternative approved suppliers to ensure the continued supply of necessary raw materials.
Government Regulations
U.S. Drug Development Process
The FDA regulates drugs under the Federal Food, Drug, and Cosmetic Act, or FDCA, and implementing regulations. Drugs are also subject to other federal, state and local statutes and regulations. Biologics are subject to regulation by the FDA under the FDCA, the Public Health Service Act, and related regulations and other federal, state and local laws and regulations. Biological products include a wide variety of products including vaccines, blood and blood components, gene therapies, tissue and proteins. Unlike most prescription products made through chemical processes, biological products generally are made from human and/or animal materials. To be lawfully marketed in interstate commerce, a biologic product must be the subject of a BLA issued by the FDA on the basis of a demonstration that the product is safe, pure and potent, and that the facility in which the product is manufactured meets standards to assure that it continues to be safe, pure and potent. The FDA has developed and is continuously updating the requirements with respect to cell and gene therapy products and has issued documents concerning the regulation of cellular and tissue-based products. Manufacturers of cell and tissue-based products must comply with the FDA’s current good tissue practices, or cGTP, which are FDA regulations that govern the methods used in, and the facilities and controls used for, the manufacture of such products. The primary intent of the cGTP requirements is to ensure that cell and tissue-based products are manufactured in a manner designed to prevent the introduction, transmission and spread of communicable disease.
The process of obtaining regulatory approvals and ensuring compliance with appropriate federal, state and local statutes and regulations in the United States, and foreign statutes and regulations, requires the expenditure of substantial time and financial resources. Failure to comply with the applicable U.S. requirements at any time during the product development process, approval process, or after approval, may subject an applicant to administrative or judicial sanctions. These sanctions could include the FDA’s refusal to approve pending applications, withdrawal of an approval, a clinical hold, warning letters, product recalls, product seizures, product detention, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties.
20
The process required by the FDA before a biological product or drug may be marketed in the United States generally involves the following:
| ● | Completion of preclinical laboratory tests, animal studies and formulation studies according to Good Laboratory Practices or other regulations; |
| ● | Submission to the FDA of an investigational new drug application, or IND, which must become effective before human clinical trials may begin; |
| ● | Performance of adequate and well-controlled clinical trials according to Good Clinical Practices, or GCP, to establish the safety and efficacy of the proposed biological product or drug for its intended use; |
| ● | Submission to the FDA of a BLA for a new biological product or a new drug application, or NDA, for a new drug; |
| ● | Satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the drug is produced to assess compliance with cGMP to assure that the facilities, methods and controls are adequate to preserve the drug’s or biologic’s identity, strength, quality and purity; and |
| ● | FDA review and approval of the BLA or NDA. |
All clinical trials must be conducted under the supervision of one or more qualified investigators in accordance with GCP regulations. These regulations include the requirement that all subjects participating in the clinical trial provide their informed consent regarding the trial. Further, an institutional review board, or IRB, must review and approve the plan for any clinical trial before it commences at any institution. An IRB considers, among other things, whether the risks to individuals participating in the trials are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the information regarding the clinical trial and the consent form that must be provided to each clinical trial subject, or his or her legal representative, and must monitor the clinical trial until completed. Once an IND is in effect, each new clinical protocol and any amendments to the protocol must be submitted to the FDA for review, and to the IRBs for approval.
Human clinical trials are typically conducted in three sequential phases that may overlap or be combined:
| ● | Phase I. The product is initially introduced into healthy human subjects and tested for safety, dosage tolerance, absorption, metabolism, distribution and excretion. In the case of some products for severe or life-threatening diseases, especially when the product may be too inherently toxic to ethically administer to healthy volunteers, the initial human testing may be conducted in patients having the specific disease. |
| ● | Phase II. Phase II clinical trials involve investigations in a limited patient population to identify possible adverse effects and safety risks, to preliminarily evaluate the efficacy of the product for specific targeted diseases and to determine dosage tolerance and the optimal dosage and schedule. |
| ● | Phase III. Phase III clinical trials are undertaken to further evaluate dosage, clinical efficacy and safety in an expanded patient population at geographically dispersed clinical trial sites. These trials are intended to establish the overall risk/benefit ratio of the product and provide an adequate basis for regulatory approval and product labeling. |
Post-approval studies, also called Phase IV trials, may be conducted after initial marketing approvals. These studies are used to obtain additional experience from the treatment of patients in the intended therapeutic indication and may be required by the FDA as part of the approval process.
Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and safety reports must be submitted to the FDA and the investigators for serious and unexpected side effects. Phase I, Phase II and Phase III testing may not be completed successfully within any specified period, if at all. The FDA or the trial sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that the study subjects or
21
patients are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance with the IRB’s requirements or if the product candidate has been associated with unexpected serious harm to patients.
Concurrent with clinical trials, companies usually complete additional animal studies and must also develop additional information about the chemistry and physical characteristics of the product and finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, the manufacturer must develop methods for testing the identity, strength, quality and purity of the final product. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the applicable product candidate does not undergo unacceptable deterioration over its shelf life.
The results of product development, preclinical studies and clinical trials, along with descriptions of the manufacturing process, analytical tests conducted on the product candidate, proposed labeling and other relevant information, are submitted to the FDA as part of an NDA or BLA, requesting approval to market the product. The submission of an NDA or BLA is subject to the payment of substantial user fees which may be waived under certain limited circumstances.
The testing and approval processes require substantial time and effort, and may not result in an approval on a timely basis, if at all. The FDA may refuse to approve a BLA or NDA if the applicable regulatory criteria are not satisfied or may require additional clinical data or other data and information. Generally, it takes one to three years to obtain approval. If questions arise during the FDA review process, approval may take a significantly longer period of time.
If a product receives regulatory approval, the approval may be significantly limited to specific diseases and dosages or the indications for use may otherwise be limited, which could restrict the commercial value of the product. Further, the FDA may require that certain contraindications, warnings or precautions be included in the product labeling. In addition, the FDA may require Phase IV testing which involves clinical trials designed to further assess a drug’s or biologic’s safety and effectiveness after BLA or NDA approval and may require testing and surveillance programs to monitor the safety of approved products that have been commercialized.
Orphan Drug Designation
Under the Orphan Drug Act of 1983, the FDA may grant orphan drug designation to drugs and biological products intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the United States or that affects more than 200,000 persons in the United States but that sales in the United States are not expected to recover the costs of developing and marketing a treatment drug. Orphan product designation does not convey any advantage in or shorten the duration of the regulatory review and approval process. Among the benefits of orphan drug designation are possible funding and tax savings to support clinical trials and for other financial incentives and a waiver of the marketing application user fee.
If a product that has orphan designation subsequently receives the first FDA approval for the disease or condition for which it has such designation, the product is entitled to orphan product exclusivity, which means that the FDA may not approve any other applications to market the same treatment for the same indication for seven years, except in limited circumstances, such as (i) the drug’s orphan designation is revoked; (ii) its marketing approval is withdrawn; (iii) the orphan exclusivity holder consents to the approval of another applicant’s product; (iv) the orphan exclusivity holder is unable to assure the availability of a sufficient quantity of drug; or (v) a showing of clinical superiority to the product with orphan exclusivity by a competitor product. Competitors, however, may receive approval of different products for the indication for which the orphan product has exclusivity or obtain approval for the same product but for a different indication for which the orphan product has exclusivity. Orphan drug status in the European Union has similar but not identical benefits in the European Union.
In December 2017, the European Commission granted Orphan Drug Designation to PRX-102 for the treatment of Fabry disease. In addition, On July 21, 2020, the FDA granted Orphan Drug Designation for alidornase alfa for the treatment of sarcoidosis.
22
Patent Term Restoration and Marketing Exclusivity
Depending upon the timing, duration and specifics of FDA marketing approval of our product candidate, some of our U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly referred to as the Hatch-Waxman Amendments. The Hatch-Waxman Amendments permit a patent restoration term of up to five years as compensation for patent term lost during product development and the FDA regulatory review process. However, patent term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the product’s approval date. The patent term restoration period is generally one-half the time between (a) the effective date of an IND and the submission date of a BLA or an NDA plus (b) the time between the submission date of a BLA or an NDA and the approval of that application. Only one patent applicable to an approved drug is eligible for the extension and the extension must be requested prior to expiration of the patent. The U.S. Patent and Trademark Office, or USPTO, in consultation with the FDA, reviews and approves the application for any patent term extension or restoration. We anticipate that we will apply for restorations of the patent term for certain of patents covering our product candidates.
Fast Track Designation
The FDA has a fast track program that is designed to facilitate the development and expedite the review of drugs to treat serious conditions and fill an unmet medical need, the purpose being to make important new drugs available to patients earlier. A drug candidate that receives Fast Track designation from the FDA is eligible for some or all of the following: more frequent meetings with the FDA to discuss the drug’s development plan and ensure collection of appropriate data needed to support drug approval; more frequent written communication from the FDA about such things as the design of the proposed clinical trials; eligibility for the FDA’s Accelerated Approval and Priority Review, if relevant criteria are met; and eligibility for Rolling Review, which allows a drug company to submit completed sections of its BLA or NDA for review by the FDA, rather than waiting until every section of the BLA or NDA is completed before the entire application can be reviewed. BLA or NDA review usually does not begin until the drug company has submitted the entire application to the FDA. We used the Rolling Review option for our taliglucerase alfa NDA, which we completed in April 2010.
In January 2018, the FDA granted Fast Track designation to PRX-102.
Accelerated Approval
Section 901 of the U.S. Food and Drug Administration Safety Innovations Act amends the FDCA to allow the FDA to base Accelerated Approval for drugs for serious conditions that fill an unmet medical need on whether the drug has an effect on a surrogate or an intermediate clinical endpoint. A surrogate endpoint used for Accelerated Approval is a marker; that is, a laboratory measurement, radiographic image, physical sign or other measure, that is thought to predict clinical benefit, but is not itself a measure of clinical benefit. An intermediate clinical endpoint is a measure of a therapeutic effect that is considered reasonably likely to predict the clinical benefit of a drug, such as an effect on irreversible morbidity and mortality. The FDA bases its decision on whether to accept the proposed surrogate or intermediate clinical endpoint on the scientific support for that endpoint. Studies that demonstrate a drug’s effect on a surrogate or intermediate clinical endpoint must be “adequate and well controlled” as required by the FDCA.
The Accelerated Approval pathway is most often used in settings in which the course of a disease is long and an extended period of time is required to measure the intended clinical benefit of a drug, even if the effect on the surrogate or intermediate clinical endpoint occurs rapidly. Under subpart H of the Accelerated Approval pathway, the FDA may grant marketing approval for a new drug product on the basis of adequate and well-controlled clinical trials establishing that the drug product has an effect on a surrogate endpoint that is reasonably likely, based on epidemiologic, therapeutic, pathophysiologic, or other evidence, to predict clinical benefit or on the basis of an effect on a clinical endpoint other than survival or irreversible morbidity. The Accelerated Approval pathway is usually contingent on a sponsor’s agreement to conduct, in a diligent manner, additional post-approval confirmatory studies to verify and describe the drug’s clinical benefit. As a result, a drug candidate approved on this basis is subject to rigorous post-marketing compliance requirements, including the completion of Phase IV or post-approval clinical trials to confirm the effect on the clinical endpoint. Failure to conduct required post-approval studies, or confirm a clinical benefit during post-
23
marketing studies, would allow the FDA to withdraw the drug from the market on an expedited basis. All promotional materials for drug candidates approved under accelerated regulations are subject to prior review by the FDA.
Post-Approval Requirements
Any drugs for which we receive FDA approval are subject to continuing regulation by the FDA, including, among other things, record-keeping requirements, reporting of adverse effects with the product, reporting of changes in distributed products which would require field alert reports (FARs), drugs and biological product deviation reports (BPDRs) providing the FDA with updated safety and efficacy information, product sampling and distribution requirements, complying with certain electronic records and signature requirements and complying with FDA promotion and advertising requirements. In September 2007, the Food and Drug Administration Amendments Act of 2007 was enacted, giving the FDA enhanced post-marketing authority, including the authority to require post marketing studies and clinical trials (PMRs and PMCs), labeling changes based on new safety information, and compliance with risk evaluations and mitigation strategies (REMS), approved by the FDA. The FDA strictly regulates labeling, advertising, promotion and other types of information on products that are placed on the market. Drugs and biologics may be promoted only for the approved indications and in accordance with the provisions of the approved label. Further, manufacturers of drugs and biologics must continue to comply with cGMP requirements, which are extensive and require considerable time, resources and ongoing investment to ensure compliance. In addition, changes to the manufacturing process generally require prior FDA approval before being implemented and other types of changes to the approved product, such as adding new indications and additional labeling claims, are also subject to further FDA review and approval.
Drug and biologic manufacturers and other entities involved in the manufacturing and distribution of approved drugs and biologics are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP, GTP applicable to biologics, and other laws. The cGMP requirements apply to all stages of the manufacturing process, including the production, processing, sterilization, packaging, labeling, storage and shipment of the drug. Manufacturers must establish validated systems to ensure that products meet specifications and regulatory standards, and test each product batch or lot prior to its release.
The FDA may withdraw a product approval if compliance with regulatory standards is not maintained or if problems occur after the product reaches the market. Discovery of previously unknown problems with a product subsequent to its approval may result in restrictions on the product or even complete withdrawal of the product from the market. Further, the failure to maintain compliance with regulatory requirements may result in administrative or judicial actions, such as fines, warning letters, holds on clinical trials, product recalls or seizures, product detention or refusal to permit the import or export of products, refusal to approve pending applications or supplements, restrictions on marketing or manufacturing, injunctions or civil or criminal penalties.
From time to time, legislation is drafted, introduced and passed in Congress that could significantly change the statutory provisions governing the approval, manufacturing and marketing of products regulated by the FDA. In addition to new legislation, the FDA regulations and policies are often revised or reinterpreted by the agency in ways that may significantly affect our business and our development efforts. It is impossible to predict whether further legislative or FDA regulation or policy changes will be enacted or implemented and what the impact of such changes, if any, may be.
Foreign Regulation
We are subject to regulations and product registration requirements in many foreign countries in which we may sell our products, including in the areas of product standards, packaging requirements, labeling requirements, import and export restrictions and tariff regulations, duties and tax requirements. The time required to obtain clearance required by foreign countries may be longer or shorter than that required for FDA clearance, and requirements for licensing a product in a foreign country may differ significantly from FDA requirements.
Pharmaceutical products may not be imported into, or manufactured or marketed in, the State of Israel absent drug registration. The three basic criteria for the registration of pharmaceuticals in Israel is quality, safety and efficacy of the pharmaceutical product and the Israeli Ministry of Health requires pharmaceutical companies to conform to international
24
developments and standards. Regulatory requirements are constantly changing in accordance with scientific advances as well as social and ethical values.
The relevant legislation of the European Union requires that medicinal products, including generic versions of previously approved products, and new strengths, dosage forms and formulations, of previously approved products, shall have a marketing authorization before they are placed on the market in the European Union. Authorizations are granted after the assessment of quality, safety and efficacy by the respective health authorities. In order to obtain an authorization, an application must be made to the competent authority of the member state concerned or in a centralized procedure to the EMA. Besides various formal requirements, the application must contain the results of pharmaceutical (physico-chemical, biological or microbiological) tests, of preclinical (toxicological and pharmacological) tests as well as of clinical trials. All of these tests must have been conducted in accordance with relevant EU regulations and must allow the reviewer to evaluate the quality, safety and efficacy of the medicinal product. Orphan drug designation in the European Union is granted to medicinal products intended for the diagnosis, prevention and treatment of life-threatening diseases and very serious conditions that affect not more than five in 10,000 people in the European Union. Orphan drug designation is generally given to medicinal products that treat conditions for which no current therapy exists or are expected to bring a significant benefit to patients over existing therapies.
Third Party Payor Coverage and Reimbursement
Coverage and reimbursement status of any approved therapy carries uncertainty and risk. In both the United States and foreign markets, our ability to commercialize our product and product candidates successfully, and to attract commercialization partners, depends in significant part on the availability of adequate financial coverage and reimbursement from third party payors, including, in the United States, governmental payors such as Medicare, Medicaid and the Veterans Affairs Health programs, and private health insurers. Medicare is a federally funded program managed by the Centers for Medicare and Medicaid Services, or CMS, through local fiscal intermediaries and carriers that administer coverage and reimbursement for certain healthcare items and services furnished to the elderly and disabled. Medicaid is an insurance program for certain categories of patients whose income and assets fall below state defined levels and who are otherwise uninsured that is both federally and state funded and managed by each state. The federal government sets general guidelines for Medicaid and each state creates specific regulations that govern its individual program. Each payor has its own process and standards for determining whether it will cover and reimburse a procedure or particular product. Private payors often rely on the lead of the governmental payors in rendering coverage and reimbursement determinations. Therefore, achieving favorable CMS coverage and reimbursement is usually a significant gating issue for successful introduction of a new product. The competitive position of some of our products will depend, in part, upon the extent of coverage and adequate reimbursement for such products and for the procedures in which such products are used. Prices at which we or our customers seek reimbursement for our product candidates can be subject to challenge, reduction or denial by the government and other payors.
Possible legislation at the federal and state levels in the United States focused on cost containment and price transparency may impact our ability to sell our product and product candidates for maximum profitably. It appears likely that the pressure on pharmaceutical pricing will continue, especially under the Medicare program, which may also increase our regulatory burdens and operating costs. Moreover, additional changes could be made to governmental healthcare programs that could significantly impact the success of our product and product candidates.
Some third party payors also require pre-approval of coverage for new or innovative devices, biologics or drug therapies before they will reimburse healthcare providers that use such therapies. While we cannot predict whether any proposed cost-containment measures will be adopted or otherwise implemented in the future, the announcement or adoption of these proposals could have a material adverse effect on our ability to obtain adequate prices for our product candidates and operate profitably.
Different pricing and reimbursement schemes exist in other countries. In the European Union, governments influence the price of pharmaceutical products through their pricing and reimbursement rules and control of national health care systems that fund a large part of the cost of those products to consumers. Some jurisdictions operate positive and negative list systems under which products may only be marketed once a reimbursement price has been agreed. To obtain reimbursement or pricing approval, some of these countries may require the completion of clinical trials that compare the cost-effectiveness of a particular product candidate to currently available therapies. Other member states
25
allow companies to fix their own prices for medicines, but monitor and control company profits. The downward pressure on health care costs in general, particularly prescription drugs and biologics, has become very intense. As a result, increasingly high barriers are being erected to the entry of new products. In addition, in some countries, cross-border imports from low-priced markets exert a commercial pressure on pricing within a country.
Other Healthcare Laws and Compliance Requirements
In the United States, our activities are potentially subject to regulation by various federal, state and local authorities in addition to the FDA, including the Centers for Medicare and Medicaid Services, other divisions of the U.S. Department of Health and Human Services (e.g., the Office of Inspector General), the U.S. Department of Justice and individual U.S. Attorney General offices within the Department of Justice, and state and local governments. These regulations include:
| ● | the federal healthcare program anti-kickback law, which prohibits, among other things, persons from soliciting, receiving or providing remuneration, directly or indirectly, to induce either the referral of an individual, for an item or service or the purchasing or ordering of a good or service, for which payment may be made under federal healthcare programs such as the Medicare and Medicaid programs; |
| ● | federal false claims laws which prohibit, among other things, individuals or entities from knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other government reimbursement programs that are false or fraudulent; |
| ● | the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which prohibits executing a scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters and which also imposes certain requirements relating to the privacy, security and transmission of individually identifiable health information; |
| ● | the federal transparency requirements under the Health Care Reform Law requires manufacturers of drugs, devices, biologics, and medical supplies to report to the Department of Health and Human Services information related to physician payments and other transfers of value and physician ownership and investment interests; |
| ● | the FDCA, which among other things, strictly regulates drug and biologic product marketing, prohibits manufacturers from marketing drug products for off-label use and regulates the distribution of drug samples; and |
| ● | state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws which may apply to items or services reimbursed by any third-party payor, including commercial insurers, and state laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and often are not preempted by federal laws, thus complicating compliance efforts. |
Compliance with Environmental, Health and Safety Laws
In addition to FDA regulations, we are also subject to evolving federal, state and local environmental, health and safety laws and regulations. In the past, compliance with environmental, health and safety laws and regulations has not had a material effect on our capital expenditures. Compliance with environmental, health and safety laws and regulations in the future may require additional capital expenditures.
Israeli Government Programs
The following is a brief summary of the current principal Israeli tax laws applicable to us and Protalix Ltd., and of the Israeli Government programs from which Protalix Ltd. benefits. Some parts of this discussion are based on new tax legislation that has not been subject to judicial or administrative interpretation. Therefore, the views expressed in the discussion may not be accepted by the tax authorities in question. This summary is based on laws and regulations in
26
effect as of the date hereof, and should not be construed as legal or professional tax advice and does not cover all possible tax considerations.
General Corporate Tax Structure in Israel
The income of Protalix Ltd., other than income from “Approved Enterprises,” is taxed in Israel at regular rates. Pursuant to the Economic Efficiency Law (Legislative Amendments for Implementing the Economic Policy for the 2017 and 2018 Budget Year), 2016, the corporate tax rate in 2018 and thereafter is 23%. Capital gains on the sale of assets are subject to capital gains tax according to the corporate tax rate in effect in the year which the assets are sold.
Law for the Encouragement of Capital Investments, 1959
The Law for the Encouragement of Capital Investments, 1959, as amended, or the Investment Law, provides certain incentives for capital investments in a production facility (or other eligible assets). Generally, an investment program that is implemented in accordance with the provisions of the Investment Law, referred to as an “Approved Enterprise,” is entitled to benefits. These benefits may include cash grants from the Israeli government and tax benefits, based upon, among other things, the location within Israel of the facility in which the investment is made and specific elections made by the grantee. In order to qualify for these incentives, an Approved Enterprise is required to comply with the requirements of the Investment Law, and Letter of approval received by Protalix Ltd.
Protalix Ltd. will continue to enjoy the tax benefits under the pre-revision provisions of the Investment Law. If any new benefits are granted to Protalix Ltd. in the future, Protalix Ltd. will be subject to the provisions of the amended Investment Law with respect to these new benefits. Therefore, the following discussion is a summary of the Investment Law prior to its amendment as well as the relevant changes contained in the new legislation.
Under the Investment Law prior to its amendment, a company that wished to receive benefits had to receive approval from the Authority for the Investment and Development of the Industry and Economy, or the Investment Center. Each certificate of approval for an Approved Enterprise relates to a specific investment program in the Approved Enterprise, delineated both by the financial scope of the investment and by the physical characteristics of the facility or the asset, e.g., the equipment to be purchased and utilized pursuant to the program.
An Approved Enterprise may elect to forego any entitlement to the grants otherwise available under the Investment Law and, instead, participate in an alternative benefits program under which the undistributed income (after deductions and offsets) from the Approved Enterprise is exempt from corporate tax for a defined period of time. Under the alternative package of benefits, a company’s undistributed income derived from an Approved Enterprise will be exempt from corporate tax for a period of between two and 10 years from the first year of taxable income, depending upon the geographic location within Israel of the Approved Enterprise. Upon expiration of the exemption period, the Approved Enterprise is eligible for the reduced tax rates otherwise applicable under the Investment Law for any remainder of the otherwise applicable benefits period (up to an aggregate benefits period of either seven or 10 years, depending on the location of the company or its definition as a foreign investors’ company). If a company has more than one Approved Enterprise program or if only a portion of its capital investments are approved, its effective tax rate is the result of a weighted combination of the applicable rates. The tax benefits from any certificate of approval relate only to taxable profits attributable to the specific Approved Enterprise and are contingent upon meeting the criteria set out in the certificate of approval. Income derived from activity that is not integral to the activity of the Approved Enterprises (including capital gain) does not enjoy these tax benefits.
A company that has an Approved Enterprise program is eligible for further tax benefits, as an alternative to exemption, if it qualifies as a foreign investors’ company. A foreign investors’ company eligible for benefits is essentially a company in which more than 25% of the share capital (in terms of shares, rights to profit, voting and appointment of directors) is owned (measured by both share capital and combined share and loan capital) by non-Israeli residents. A company that qualifies as a foreign investors’ company and has an Approved Enterprise program is eligible for tax benefits for a 10-year benefit period and may enjoy a reduced corporate tax rate of 10% to 23%, depending on the amount of the company’s shares held by non-Israeli shareholders.
27
If a company that has an Approved Enterprise program is a wholly-owned subsidiary of another company, the percentage of foreign investments is determined based on the percentage of foreign investment in the parent company. The tax rates and related levels of foreign investments with respect to a foreign investor’s company that has an Approved Enterprise program are set forth in the following table:

Our original facility in Israel has been granted “Approved Enterprise” status, and it has elected to participate in the alternative benefits program. Under the terms of its Approved Enterprise program, the facility is located in a Zone A area and, therefore, the undistributed income from that Approved Enterprise will be tax exempt in Israel for a period of 10 years, commencing with the year in which taxable income is first generated from the relevant Approved Enterprise. The current benefits program may not continue to be available and Protalix Ltd. may not continue to qualify for its benefits.
A company that has elected to participate in the alternative benefits program and that subsequently pays a dividend out of the income derived from the portion of its facilities that have been granted Approved Enterprise status during the tax exemption period will be subject to corporate tax in respect of the amount of dividend distributed at the rate that would have been applicable had the company not elected the alternative benefits program (generally 10% to 23%, depending on the extent to which non-Israeli shareholders hold such company’s shares). If the dividend is distributed within 12 years after the end of the benefits period (or, in the case of a foreign investor’s company, without time limitation), the dividend recipient is taxed at the reduced withholding tax rate of 20% applicable to dividends from approved enterprises, or at the lower rate under an applicable tax treaty. After this period, the withholding tax rate is 25% to 30%, or at the lower rate under an applicable tax treaty. In the case of a company with a foreign investment level (as defined by the Investment Law) of 25% or more, the 12-year limitation on reduced withholding tax on dividends does not apply. The company must withhold this tax at its source, regardless of whether the dividend is converted into foreign currency.
The Investment Law also provides that an Approved Enterprise is entitled to accelerated depreciation on its property and equipment that are included in an approved investment program. This benefit is an incentive granted by the Israeli government regardless of whether the alternative benefits program is elected.
The benefits available to an Approved Enterprise are conditioned upon terms stipulated in the Investment Law and its regulations and the criteria set forth in the applicable certificate of approval. If Protalix Ltd. does not fulfill these conditions in whole or in part, the benefits can be canceled and Protalix Ltd. may be required to refund the benefits received, linked to the Israeli consumer price index with interest. We believe that Protalix Ltd. currently operates in compliance with all applicable conditions and criteria.
Amendment No. 60 to the Investment Law introduced a tax benefits regime referred to as “Benefitted Enterprises.” Under the Investment Law, the approval of the Investment Center is required only for Benefitted Enterprises that receive cash grants. Benefitted Enterprises that do not receive benefits in the form of governmental cash grants, but only tax benefits, are no longer required to obtain this approval. Instead, these Benefitted Enterprises are required to make certain investments as specified in the Investment Law.
The amended Investment Law specifies certain conditions for a Benefitted Enterprise to be entitled to benefits. These conditions include, inter alia, the following:
| ● | the Benefitted Enterprise’s revenues from any single country or a separate customs territory may not exceed 75% of the Benefitted Enterprise’s total revenues; or |
| ● | at least 25% of the Benefitted Enterprise’s revenues during the benefits period must be derived from sales into a single country or a separate customs territory with a population of at least 14 million people (starting from January 1, 2012, 1.4% must be added for each year). |
28
There can be no assurance that Protalix Ltd. will comply with the above conditions in the future or that Protalix Ltd. will be entitled to any additional benefits under the Investment Law. In addition, it is possible that Protalix Ltd. may not be able to operate in a manner that maximizes utilization of the potential benefits available under the Investment Law.
In the future there may be changes in the law, subject to the preservation of benefits, which may affect the benefits available to companies under the Investment Law. The termination or substantial reduction of any of the benefits available under the Investment Law could impact our tax expenses.
Amendment of the Law for the Encouragement of Capital Investments, 1959
In recent years, several amendments have been made to the Investments Law which have enabled new alternative benefit tracks, subject to certain conditions. The Investments Law was amended as part of the Economic Policy Law for the years 2011-2012 (amendment 68 to the Encouragement of Capital Investments Law), which was passed by the Israeli Knesset on December 29, 2010. The amendment sets alternative benefit tracks to those currently in effect under the provisions of the Investments Law. On December 29, 2016, Amendment 73 to the Investments Law, or the Investments Law Amendment, was published. This amendment sets new benefit tracks, inter alia, “Preferred Technological Enterprise” and “Special Preferred Technological Enterprise.” To date, we have elected not to have the Investments Law Amendment apply to our company.
Encouragement of Industrial Research, Development and Technology Innovation Law, 1984
To date, Protalix Ltd. has received grants from the Office of the Chief Scientist of the Israeli Department of Labor, or the OCS under the Israeli Law for the Encouragement of Industrial Research, Development and Technology Innovation, 1984, and related regulations, or the Research Law. On January 1, 2016, the Israeli government established the National Authority for Technological Innovation, or NATI, which replaced many of the functions of the OCS. For purposes of clarity, references to NATI will include the OCS. NATI grants are made available to finance of a portion of Protalix Ltd.’s research and development expenditures in Israel. As of December 31, 2021, NATI approved grants in respect of Protalix Ltd.’s continuing operations totaling approximately $53.2 million (before interest, as described below), measured from inception. Protalix Ltd. is required to repay up to 100% of grants actually received (plus interest at the LIBOR rate applied to the grants received on or after January 1, 1999) to NATI through payments of royalties at a rate of 3% to 6% of the revenues generated from NATI-funded project, depending on the period in which revenues were generated. As of December 31, 2021, Protalix Ltd. either paid or accrued royalties payable of $14.6 million, and Protalix Ltd.’s contingent liability to NATI with respect to grants received was approximately $38.6 million.
Under the Research Law, recipients of grants from NATI are prohibited from manufacturing products developed using these grants outside of the State of Israel without special approvals, although the Research Law does enable companies to seek prior approval for conducting manufacturing activities outside of Israel without being subject to increased royalties. If Protalix Ltd. receives approval to manufacture the products developed with government grants outside of Israel, it will be required to pay an increased total amount of royalties (possibly up to 300% of the grant amounts plus interest), depending on the manufacturing volume that is performed outside of Israel, as well as at a possibly increased royalty rate.
Additionally, under the Research Law, Protalix Ltd. is prohibited from transferring NATI-financed technologies and related intellectual property rights outside of the State of Israel, except under limited circumstances and only with the approval of NATI Council or the Research Committee. Protalix Ltd. may not receive the required approvals for any proposed transfer and, if received, Protalix Ltd. may be required to pay NATI a portion of the consideration that it receives upon any sale of such technology by a non-Israeli entity. The scope of the support received, the royalties that Protalix Ltd. has already paid to NATI, the amount of time that has elapsed between the date on which the know-how was transferred and the date on which NATI grants were received and the sale price and the form of transaction will be taken into account in order to calculate the amount of the payment to NATI. Approval of the transfer of technology to residents of the State of Israel is required, and may be granted in specific circumstances only if the recipient abides by the provisions of applicable laws, including the restrictions on the transfer of know-how and the obligation to pay royalties. No assurance can be made that approval to any such transfer, if requested, will be granted.
29
Under the Research Law and the regulations promulgated thereunder, NATI Council may allow the transfer outside of Israel of know-how derived from an approved program and the related manufacturing rights in limited circumstances which are currently as follows:
| ● | in the event of a sale of know-how itself to a non-affiliated third party, provided that upon such sale the owner of the know-how pays to NATI an amount, in cash, as set forth in the Research Law (and the regulations promulgated thereunder). In addition, the amendment provides that if the purchaser of the know-how gives the selling Israeli company the right to exploit the know-how by way of an exclusive, irrevocable and unlimited license, the research committee may approve such transfer in special cases without requiring a cash payment. |
| ● | in the event of a sale of a company which is the owner of know-how, pursuant to which the company ceases to be an Israeli company, provided that upon such sale, the owner of the know-how makes a cash payment to NATI as set forth in the Research Law (and the regulations promulgated thereunder). |
| ● | in the event of an exchange of know-how such that in exchange for the transfer of know-how outside of Israel, the recipient of the know-how transfers other know-how to the company in Israel in a manner in which NATI is convinced that the Israeli economy realizes a greater, overall benefit from the exchange of know-how. |
The Research Committee may, in special cases, approve the transfer of manufacture or of manufacturing rights of a product developed within the framework of the approved program or which results therefrom, outside of Israel.
The State of Israel does not own intellectual property rights in technology developed with NATI funding and there is no restriction on the export of products manufactured using technology developed with NATI funding. The technology is, however, subject to transfer of technology and manufacturing rights restrictions as described above. For a description of such restrictions, please see “Risk Factors—Risks Relating to Our Operations in Israel.” NATI approval is not required for the export of any products resulting from the research or development or for the licensing of any technology in the ordinary course of business.
Law for the Encouragement of Industry (Taxes), 1969
We believe that Protalix Ltd. currently qualifies as an “Industrial Company” within the meaning of the Law for the Encouragement of Industry (Taxes), 1969, or the Industry Encouragement Law. The Industry Encouragement Law defines “Industrial Company” as a company resident in Israel and incorporated in Israel, that derives 90% or more of its income in any tax year (other than specified kinds of passive income such as capital gains, interest and dividends) from an “Industrial Enterprise” operating in Israel (including Judea & Samaria territories and the Gaza strip), that it owns. An “Industrial Enterprise” is defined as an enterprise whose major activity in a given tax year is industrial production.
The following corporate tax benefits, among others, are available to Industrial Companies:
| ● | amortization of the cost of purchased know-how and patents over an eight-year period for tax purposes; |
| ● | accelerated depreciation rates on equipment and buildings; |
| ● | under specified conditions, an election to file consolidated tax returns with other related Israeli Industrial Companies; and |
| ● | expenses related to a public offering are deductible in equal amounts over three years. |
Eligibility for the benefits under the Industry Encouragement Law is not subject to receipt of prior approval from any governmental authority. It is possible that Protalix Ltd. may fail to qualify or may not continue to qualify as an “Industrial Company” or that the benefits described above will not be available in the future.
Tax Benefits for Research and Development
Under specified conditions, Israeli tax laws allow a tax deduction by a company for research and development expenditures, including capital expenditures, for the year in which such expenditures are incurred. These expenditures
30
must relate to scientific research and development projects and must be approved by NATI. Furthermore, the research and development projects must be for the promotion of the company and carried out by or on behalf of the company seeking such tax deduction. However, the amount of such deductible expenditures is reduced by the sum of any funds received through government grants for the finance of such scientific research and development projects. Research and development expenses which were not approved shall be deductible over a period of three years.
Employees
As of December 31, 2021, we had 206 employees of whom 202 are full time employees and 20 have a Ph.D. or an M.D. in their respective scientific fields. We believe that our relations with these employees are good. We believe that our success will greatly depend on our ability to identify, attract and retain capable employees. The Israeli Ministry of Labor and Welfare is authorized to make certain industry-wide collective bargaining agreements, or Expansion Orders, that apply to types of industries or employees including ours. These agreements affect matters such as cost of living adjustments to salaries, length of working hours and week, recuperation, travel expenses, and pension rights. Otherwise, our employees are not represented by a labor union or represented under a collective bargaining agreement. See “Risk Factors—We depend upon key employees and consultants in a competitive market for skilled personnel. If we are unable to attract and retain key personnel, it could adversely affect our ability to develop and market our products.”

Item 1A. Risk Factors
You should carefully consider the risks described below together with the other information included in this Annual Report on Form 10-K. Our business, financial condition or results of operations could be adversely affected by any of these risks. If any of these risks occur, the value of our common stock could decline. For a summary of the risk factors included in this Item 1A and for further details on our forward-looking statements, see “Forward-Looking Statements and Summary of Risk Factors” on page 1.
Risks Related to the COVID-19 Pandemic
The COVID-19 pandemic, or any other pandemic, epidemic or outbreak of an infectious disease, may adversely affect our business, results of operations and financial condition.
In December 2019, a novel strain of coronavirus, COVID-19, was identified in Wuhan, China. The virus has spread globally. To date, our clinical trials have not been adversely affected by COVID-19, although certain practices we have adopted in our offices and facilities in an effort to promote social distancing have resulted in minor delays in the performance of administrative activities outside of the clinical programs. The spread of an infectious disease, including COVID-19, may result in the inability of our suppliers to deliver components or raw materials on a timely basis. In addition, hospitals may reduce staffing and reduce or postpone certain treatments in response to the spread of an infectious disease, including the diversion of hospitals serving as our clinical trial sites and hospital staff supporting the conduct of clinical trials. Such events may result in a period of business and manufacturing disruption, and in reduced operations, any of which could materially affect our business, financial condition and results of operations. While the extent of the impact of the current COVID-19 pandemic on our business and financial results depends on future developments that are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of the coronavirus and the actions to contain the coronavirus or treat its impact, among others, a continued and prolonged public health crisis such as the COVID-19 pandemic may adversely affect our business, results of operations and financial condition.
Travel restrictions related to the COVID-19 pandemic have delayed FDA and other regulatory authority inspections of our facilities required for marketing approvals and there is no certainty with respect to the timing of such inspections.
We are subject to inspection by the FDA and comparable foreign regulatory authorities to determine our compliance with applicable regulatory requirements, as are our suppliers, contract manufacturers, and contract testing laboratories. The FDA had advised us that it requires an inspection of our manufacturing facility and the facility of a third party in Europe that performs fill and finish processes for PRX-102 as part of the FDA’s review of the BLA application, after resubmission. Due to the FDA’s travel restrictions resulting from the pandemic, the FDA was unable to conduct the required inspection during the review cycle for the initial BLA. Also, with respect to the third-party facility in Europe at which fill and finish processes are performed for PRX-102, the FDA reviewed records under Section 704(a)(4) of the Federal Food, Drug and Cosmetic Act in lieu of a pre-licensing meeting. The FDA explained in the letter that it will continue to monitor the public health situation as well as travel restrictions and is actively working to define an approach for scheduling outstanding inspections. We cannot predict when such inspections will take place. Once such inspections are able to be conducted, if the facilities are not in substantial compliance with cGMP, there may be adverse consequences to the approval process. Delays in the approval process or our inability to obtain approval for any reason for any drug candidate may have a material adverse effect upon our business, results of operations and financial condition.
Risks Related to Clinical Trials and Regulatory Matters
We may not obtain the necessary U.S., EMA or other worldwide regulatory approvals to commercialize our drug candidates in a timely manner, if at all, which would have a material adverse effect on our business, results of operations and financial condition.
To commercialize our drug candidates worldwide, we need FDA Approval, EMA approval and approvals from other foreign regulators to commercialize our drug candidates elsewhere, as applicable. In order to obtain FDA approval of
32
any of our drug candidates, we must submit to the FDA a BLA or an NDA demonstrating that the drug candidate is safe and effective for its intended use. This demonstration requires significant research and animal tests, which are referred to as preclinical studies, as well as human tests, which are referred to as clinical trials. In the European Union, we must submit an MAA to the EMA. Satisfaction of the regulatory requirements of the FDA, EMA and other foreign regulatory authorities typically takes many years, depends upon the type, complexity and novelty of the drug candidate and requires substantial resources for research, development and testing.
Companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in advanced or late-stage clinical trials, even after obtaining promising earlier trial results or in preliminary findings or other comparable authorities for such clinical trials. Further, even if favorable testing data is generated by the clinical trials of a drug candidate, the applicable regulatory authority may not accept or approve a marketing application we file for the drug candidate or may require us to conduct additional clinical testing or perform post-marketing studies which would cause us to incur additional costs.
We also cannot assure you that the results of our ongoing BALANCE study will demonstrate that our product candidates are safe and effective for their intended uses.
Failure to obtain approval of the FDA, EMA or comparable foreign authorities of any of our drug candidates in a timely manner, if at all, will severely undermine our business, financial condition and results of operation by reducing our potential marketable products and our ability to generate corresponding product revenues.
In light of our receipt of a CRL from the FDA regarding our BLA for PRX-102, the U.S. regulatory requirements and timing for PRX-102 approval are uncertain; we are substantially dependent on receipt of regulatory approvals for PRX-102, our most advanced product candidate.
The CRL issued by the FDA in response to the PRX-102 BLA did not report any concerns relating to the potential safety or efficacy of PRX-102 in the submitted data package. However, in the CRL, the FDA noted that agalsidase beta (Fabrazyme), a therapy used to treat Fabry patients, was recently converted to full approval which must be addressed in the context of any potential resubmission seeking accelerated approval of PRX-102. Although the FDA, at the Type A meeting held on September 9, 2021, in principle, agreed that the data package proposed for the BLA resubmission has the potential to support a traditional approval of PRX-102 for the treatment of Fabry disease thereby confirming a potential pathway for resubmission of a BLA for PRX-102, we can not guarantee when, or if, we will be successful in receiving regulatory approval for PRX-102. The regulatory requirements and timing for approval are uncertain at this time. If we do not obtain approval for PRX-102 or are delayed in obtaining such approval, it would have a material and adverse effect on our operations and financial condition.
The FDA may request additional data or impose other conditions in connection with a resubmission or approval. We cannot assure you that the FDA will eventually approve PRX-102 on a resubmission.
In addition, we may incur significant additional expenditures in order to obtain or maintain FDA approval. Any approval of the resubmitted BLA may also be subject to post-marketing commitments or requirements, and we may need to develop and/or improve certain antibody or additional assays as post-marketing requirements or commitments. Even if we comply with all the requests of regulatory authorities, the FDA and other authorities may ultimately reject the BLA or any other marketing application that we file for a product candidate in the future, if any, or we might not obtain regulatory clearance in a timely manner.
The Fast Track designation for pegunigalsidase alfa for the treatment of Fabry disease may not lead to a faster development or regulatory review or approval process or increase the likelihood that pegunigalsidase alfa will receive regulatory approval for the treatment of Fabry disease.
The FDA has granted Fast Track designation to pegunigalsidase alfa for the treatment of Fabry disease. As noted above, there can be no assurance that pegunigalsidase alfa will receive regulatory approval for the treatment of Fabry disease and following the receipt of the CRL timing for resubmission and the regulatory review process is uncertain. Despite the designation, we may not experience a faster development process, review or approval compared to applications considered for approval under conventional FDA procedures. In addition, the FDA is entitled to withdraw the Fast Track
33
designation of a drug candidate at any time. Any failure to realize the benefits of Fast Track designation may have a material adverse effect on our business, results of operations and financial condition.
We are subject to extensive governmental regulation including the requirements of the FDA and other comparable regulatory authorities before our drug candidates may be marketed.
Both before and after marketing approval of our drug candidates, if at all, we, our drug candidates, our suppliers, our contract manufacturers and our contract testing laboratories are subject to extensive regulation by the FDA and comparable foreign regulatory authorities. Failure to comply with applicable requirements of the FDA or comparable foreign regulatory authorities could result in, among other things, any of the following actions:
| ● | warning letters; |
| ● | fines and other monetary penalties; |
| ● | unanticipated expenditures; |
| ● | delays in the FDA’s or other foreign regulatory authorities’ approving, or the refusal of any regulatory authority to approve, any drug candidate; |
| ● | product recall or seizure; |
| ● | interruption of manufacturing or clinical trials; |
| ● | operating restrictions; |
| ● | injunctions; and |
| ● | criminal prosecutions. |
In addition to the approval requirements, other numerous and pervasive regulatory requirements apply, both before and after approval, to us, our drug candidates, our suppliers, contract manufacturers, and contract testing laboratories. These include requirements related to:
| ● | testing; |
| ● | manufacturing; |
| ● | quality control; |
| ● | labeling; |
| ● | advertising; |
| ● | promotion; |
| ● | distribution; |
| ● | export; |
| ● | reporting to the FDA certain adverse experiences associated with use of the drug candidate; and |
| ● | obtaining additional approvals for certain modifications to the drug candidate or its labeling or claims. |
We also are subject to inspection by the FDA and comparable foreign regulatory authorities, to determine our compliance with regulatory requirements, as are our suppliers, contract manufacturers, and contract testing laboratories,
34
and there can be no assurance that the FDA, or any other comparable foreign regulatory authority, will not identify compliance issues that may disrupt production or distribution, or require substantial resources to correct. We may be required to make modifications to our manufacturing operations in response to these inspections which may require significant resources and may have a material adverse effect upon our business, results of operations and financial condition.
The approval process for any drug candidate may also be delayed by changes in government regulation, future legislation or administrative action or changes in policy of the FDA and comparable foreign authorities that occur prior to or during their respective regulatory reviews of such drug candidate.
Delays in obtaining regulatory approvals with respect to any drug candidate will materially and adversely affect our prospects, business, results of operations and financial condition.
Delays in obtaining regulatory approvals with respect to any drug candidate may:
| ● | delay commercialization of, and our ability to derive product revenues from, such drug candidate; |
| ● | delay any regulatory-related milestone payments payable under outstanding collaboration agreements; |
| ● | require us to perform costly procedures with respect to such drug candidate; or |
| ● | otherwise diminish any competitive advantages that we may have with respect to such drug candidate. |
Delays in the approval process for any drug candidate will have a material adverse effect upon our prospects, business, results of operations and financial condition.
Clinical trials are very expensive, time-consuming and difficult to design and implement and may result in unforeseen costs, which may have a material adverse effect on our business, results of operations and financial condition.
Human clinical trials are very expensive and difficult to design and implement, in part because they are subject to rigorous regulatory requirements. Preliminary and initial results from a clinical trial do not necessarily predict final results, and failure can occur at any stage of the trial. We may encounter problems that cause us to abandon or repeat preclinical studies or clinical trials. The clinical trial process is also time-consuming. Failure or delay in the commencement or completion of our clinical trials may be caused by several factors, including:
| ● | slower than expected rates of patient recruitment, particularly with respect to trials of rare diseases such as Fabry disease; |
| ● | determination of dosing issues; |
| ● | unforeseen safety issues; |
| ● | lack of effectiveness during clinical trials; |
| ● | disagreement by applicable regulatory bodies over our trial protocols, the interpretation of data from preclinical studies or clinical trials or conduct and control of clinical trials; |
| ● | determination that the patient population participating in a clinical trial may not be sufficiently broad or representative to assess efficacy and safety for our target population; |
| ● | inability to monitor patients adequately during or after treatment; |
| ● | inability or unwillingness of medical investigators and institutional review boards to follow our clinical protocols; and |
35
| ● | lack of sufficient funding to finance the clinical trials. |
Any failure or delay in commencement or completion of any clinical trials of pegunigalsidase alfa or our other product candidates will have a material adverse effect on our business, results of operations and financial condition. In addition, we or the FDA or other regulatory authorities may suspend any clinical trial at any time if it appears that we are exposing participants in the trial to unacceptable safety or health risks or if the FDA or such other regulatory authorities, as applicable, find deficiencies in our IND submissions or the conduct of the trial. Any suspension of a clinical trial may have a material adverse effect on our business, results of operations and financial condition.
If the results of our clinical trials do not support our claims relating to a drug candidate, or if serious side effects are identified, the completion of development of such drug candidate may be significantly delayed or we may be forced to abandon development altogether, which will significantly impair our ability to generate product revenues.
The results of our clinical trials with respect to any drug candidate might not support our claims of safety or efficacy, the results of our clinical trials may fail to conclusively show superiority over other commercially available treatments for the same or similar indications, the effects of our drug candidates may not be the desired effects or may include undesirable side effects or the drug candidates may have other unexpected characteristics. Data obtained from tests are susceptible to varying interpretations which may delay, limit or prevent regulatory approval. The clinical trial process may fail to demonstrate that our drug candidates are safe for humans and effective for indicated uses. In addition, our clinical trials, may involve specific and small patient populations. Results of early clinical trials conducted on a small patient population may not be indicative of future results. Adverse or inconclusive results may cause us to abandon a drug candidate and may delay development of other drug candidates. Any delay in, or termination of, our clinical trials will delay the filing of BLAs and NDAs with the FDA, or other filings with other foreign regulatory authorities, and, ultimately, significantly impair our ability to commercialize our drug candidates and generate product revenues which would have a material adverse effect on our business, results of operations and financial condition.
Interim, topline or preliminary data from clinical trials that we announce or publish may change as more patient data becomes available and are subject to audit and verification procedures that could result in material changes in the final data.
We may publicly disclose interim, topline or preliminary data from our clinical trials, which is based on a preliminary analysis of then-available data. The results and related findings and conclusions are subject to change following a full analysis of all data related to the particular trial. We also may make assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. As a result, any interim, topline or preliminary results that we report may differ from future results of the same trials, or different conclusions or considerations may qualify such results once additional data have been received and fully evaluated. Topline data also remain subject to audit and verification procedures that may result in the final data being materially different than the preliminary data we previously publish. As a result, any topline data should be viewed with caution until final data are available. Interim data from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more data becomes available. Further, regulatory agencies may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses, or may interpret or ascribe different weight to the data, which may impact the value of the clinical trial and may affect the particular clinical program and the approvability or commercialization of the particular product candidate and our business in general. If regulatory authorities disagree with the conclusions we reach, we may not be able to obtain approval for and commercialize our product candidates, which will have a material adverse effect on our business, results of operations and financial condition.
We may find it difficult to enroll patients in our clinical trials, or patients may discontinue their participation in our clinical trials, which could cause significant delays in the completion of such trials or may negatively impact the results of these studies and extend the timeline for completion of our development programs or cause us to abandon one or more clinical trials.
Some of the diseases or disorders that our drug candidates are intended to treat are relatively rare and we expect only a subset of the patients with these diseases to be eligible for our clinical trials. Our clinical trials generally mandate that a
36
patient cannot be involved in another clinical trial for the same indication. Therefore, subjects that participate in ongoing clinical trials for products that are competitive with our drug candidates are not available for our clinical trials. An inability to enroll a sufficient number of patients for any of our clinical trials would result in significant delays or may require us to abandon one or more clinical trials altogether. In addition, patients that enroll in our clinical trials may discontinue their participation at any time during the study as a result of a number of factors, including withdrawing their consent, experiencing adverse clinical events, which may or may not be judged related to our drug candidates under evaluation, or due to planned or actual pregnancies. The discontinuation of patients in any one of our studies may delay the completion of the study or cause the results from the study not to be positive or to not support a filing for regulatory approval of the applicable drug candidate. Any failure to enroll a sufficient number of patients in our clinical trials in a timely manner, if at all, may have a material adverse effect on our business, results of operations and financial condition.
Because our clinical trials depend upon third-party researchers, the results of our clinical trials and such research activities are subject to delays and other risks which are, to a certain extent, beyond our control, which could impair our clinical development programs and our competitive position.
We depend upon independent investigators and collaborators, such as universities and medical institutions, to conduct our preclinical and clinical trials. These collaborators are not our employees, and we cannot control the amount or timing of resources that they devote to our clinical development programs. The investigators may not assign as great a priority to our clinical development programs or pursue them as diligently as we would if we were undertaking such programs directly. If outside collaborators fail to devote sufficient time and resources to our clinical development programs, or if their performance is substandard, the approval of anticipated NDAs, BLAs and other marketing applications, and our introduction of new drugs, if any, may be delayed which could impair our clinical development programs and would have a material adverse effect on our business, results of operations and financial condition. Our collaborators may also have relationships with other commercial entities, some of whom may compete with us. If our collaborators also assist our competitors, our competitive position could be harmed.
We have only limited experience in regulatory affairs, and some of our drug candidates may be based on new technologies. These factors may affect our ability or the time we require to obtain necessary regulatory approvals.
We have only limited experience in filing and prosecuting the applications necessary to gain regulatory approvals for medical devices and drug candidates. Moreover, some of the drug candidates that are likely to result from our development programs may be based on new technologies that have not been extensively tested in humans. The regulatory requirements governing these types of drug candidates may be less well defined or more rigorous than for conventional products. As a result, we may experience a longer regulatory process in connection with obtaining regulatory approvals of any products that we develop, which may have a material adverse effect on our business, results of operations and financial condition.
Orphan drug designation may not ensure that we will enjoy market exclusivity in any jurisdiction. If any of our other competitors are able to obtain orphan drug exclusivity for any products that are competitive with our products, we may be precluded from selling or obtaining approval of our competing products by the applicable regulatory authorities for a significant period of time.
In the United States, the European Union and other countries, a drug may be designated as having orphan drug status, subject to certain conditions. There can be no assurance that a drug candidate that receives orphan drug designation will receive orphan drug marketing exclusivity and more than one drug can have orphan designation for the same indication. In addition, the orphan drug designation granted to pegunigalsidase alfa by the EMA does not affect Fabry disease treatments that preexist the approval of pegunigalsidase alfa, if at all.
From time to time, we may apply to the FDA or any comparable foreign regulatory authority for orphan drug designation for any one or more of our drug candidates. Other than pegunigalsidase alfa which was granted orphan drug designation by the EMA, none of our drug candidates have been designated as an orphan drug and there is no guarantee that the FDA or any other regulatory authority will grant such designation in the future. In addition, neither orphan drug designation nor orphan drug exclusivity prevents competitors from developing or marketing different drugs for the relevant indication. Even if we obtain orphan drug exclusivity for one or more indications for one of our drug candidates, we may not be able to maintain the exclusivity. For example, if a competitive product that is the same drug or biologic as
37
one of our drug candidates is shown to be clinically superior to the drug candidate, any orphan drug exclusivity granted to the drug candidate will not block the approval of the competitive product.
If any drug receives orphan drug exclusivity in any jurisdiction for the same indication of any of our drug candidates, we may be prevented from attaining a similar designation with respect to our drug candidate or from marketing the drug candidate in the jurisdiction during the applicable exclusivity period, which will have a material adverse effect on our business, results of operations and financial condition.
Risks Related to Our Business
We have a limited operating history which may limit the ability of investors to make an informed investment decision.
Taliglucerase alfa is our only commercial product. The successful commercialization of our other drug candidates will require us to perform a variety of functions, including:
| ● | continuing to perform preclinical development and clinical trials; |
| ● | participating in regulatory approval processes; |
| ● | formulating and manufacturing products; and |
| ● | conducting sales and marketing activities. |
Our operations have been limited to organizing and staffing our company, acquiring, developing and securing our proprietary technology and undertaking, through third parties, preclinical trials and clinical trials of our principal drug candidates. These operations provide a limited basis for investors to assess our ability to commercialize our drug candidates and whether to invest in our company.
We currently depend heavily on the success of pegunigalsidase alfa. Any failure to commercialize pegunigalsidase alfa, or the experience of significant delays in doing so, will have a material adverse effect on our business, results of operations and financial condition.
We are investing a significant portion of our efforts and financial resources in the development of pegunigalsidase alfa and our ability to generate significant product revenues in the future, will depend heavily on the successful development and commercialization of pegunigalsidase alfa. The successful commercialization of pegunigalsidase alfa will depend on several factors, including the following:
| ● | Chiesi’s efforts under the Chiesi Agreements; |
| ● | obtaining marketing approvals from the FDA, EMA and other foreign regulatory authorities; |
| ● | maintaining the cGMP compliance of our manufacturing facility or establishing manufacturing arrangements with third parties; |
| ● | the successful inspection of our facilities by the FDA and other foreign regulatory authorities; |
| ● | Chiesi’s development of successful sales and marketing organizations for pegunigalsidase alfa; |
| ● | the availability of coverage or reimbursement to patients from healthcare payors for pegunigalsidase alfa, if approved; |
| ● | a continued acceptable safety and efficacy profile of pegunigalsidase alfa following approval; and |
| ● | other risks described in these Risk Factors. |
38
Any failure to commercialize pegunigalsidase alfa or the experience of significant delays in doing so will have a material adverse effect on our business, results of operations and financial condition.
Any failure by us to supply drug substance to Pfizer may have a material adverse effect on our business, results of operations and financial condition.
Under the Amended Pfizer Agreement, we have agreed, for the first 10-year period after the execution of the agreement, to sell drug substance to Pfizer for the production of Elelyso, and Pfizer maintains the right to extend the supply period for up to two additional 30-month periods subject to certain terms and conditions. As part of that obligation, we agreed to substantial financial penalties if we fail to comply with the supply commitments, or are delayed in doing so. The amounts of the penalties depend on when any such failure occurs and for how long it persists, if at all, and other considerations. Any failure to comply with the supply commitments under the Amended Pfizer Agreement may have a material adverse effect on our business, results of operations and financial condition.
Our strategy, in certain cases, is to enter into collaboration agreements with third parties to leverage our ProCellEx system to develop product candidates. Failure to enter into such agreements, or non-compliance by us or our collaborators with such agreements, may have a material adverse effect on our business, results of operations and financial condition.
Our strategy, in certain cases, is to enter into arrangements with pharmaceutical companies to leverage our ProCellEx system to develop additional product candidates. Under these arrangements, we may grant to our partners rights to license and commercialize pharmaceutical products developed under the applicable agreements, as we have done with Elelyso and pegunigalsidase alfa. Our partners may control key decisions relating to the development of the products and we may depend on our partners’ expertise and dedication of sufficient resources to develop and commercialize our product candidates. The rights of our partners limit our flexibility in considering alternatives for the commercialization of our product candidates. If we or any of our current or future partners breach or terminate the agreements that make up such arrangements, our partners otherwise fail to conduct their obligations under such arrangements in a timely manner, there is a dispute about their obligations or if either party terminates the applicable agreement or elects not to continue the arrangement, we may not enjoy the benefits of the agreements or receive a sufficient amount of royalty or milestone payments from them, if any, which may have a material adverse effect on our business, results of operations and financial condition.
If we are unable to develop and commercialize our product candidates, our business will be adversely affected.
A key element of our strategy is to develop and commercialize a portfolio of new products in addition to taliglucerase alfa. We seek to do so through our internal research programs and strategic collaborations for the development of new products. Research programs to identify new product candidates require substantial technical, financial and human resources, whether or not any product candidates are ultimately identified. Our research programs may initially show promise in identifying potential product candidates, yet fail to yield product candidates for clinical development for many reasons, including the following:
| ● | a product candidate is not capable of being produced in commercial quantities at an acceptable cost, or at all; |
| ● | a product candidate may not be accepted by patients, the medical community or third-party payors; |
| ● | competitors may develop alternatives that render our product candidates obsolete; |
| ● | the research methodology used may not be successful in identifying potential product candidates; or |
| ● | a product candidate may on further study be shown to have harmful side effects or other characteristics that indicate it is unlikely to be effective or otherwise does not meet applicable regulatory approval. |
Any failure to develop or commercialize any of our other product candidates may have a material adverse effect on our business, results of operations and financial condition.
39
The manufacture of our products is an exacting and complex process, and any manufacturing problems encountered by us or certain of our suppliers may have a material adverse effect on our business, results of operations and financial condition.
The FDA and foreign regulators require manufacturers to register manufacturing facilities. The FDA and foreign regulators also inspect these facilities to confirm compliance with cGMP or similar requirements that the FDA or foreign regulators establish. We or certain of our materials suppliers may face manufacturing or quality control problems causing product production and shipment delays or a situation where we or the supplier may not be able to maintain compliance with the FDA’s cGMP requirements, or those of foreign regulators, necessary to continue manufacturing. To date, our current facility has passed audits by the FDA and a number of other regulatory authorities but remains subject to audit by other foreign regulatory authorities. There can be no assurance that we will be able to comply with FDA or foreign regulatory manufacturing requirements for our current facility or any facility we may establish in the future, and the failure to so comply will have a material adverse effect on our business, results of operations and financial condition.
We rely on third parties for final processing of taliglucerase alfa, pegunigalsidase alfa and our other product candidates, which exposes us to a number of risks that may delay development, regulatory approval and commercialization of taliglucerase alfa and our other product candidates or result in higher product costs.
We have no experience in the final filling and freeze drying steps of the drug manufacturing process. We rely on third parties in the United States and Europe to perform fill and finish activities for taliglucerase alfa and pegunigalsidase alfa, and have engaged other parties for our other product candidates. We may be unable to identify manufacturers and/or replacement manufacturers on acceptable terms or at all because the number of potential manufacturers is limited and the FDA and other regulatory authorities, as applicable, must approve any manufacturer and/or replacement manufacturer, including us, and we or any such third party manufacturer might be unable to formulate and manufacture our drug products in the volume and of the quality required to meet our clinical and commercial needs. If we engage any contract manufacturers, such manufacturers may not perform as agreed or may not remain in the contract manufacturing business for the time required to supply our clinical or commercial needs. In addition, contract manufacturers are subject to the rules and regulations of the FDA and comparable foreign regulatory authorities and face the risk that any of those authorities may find that they are not in compliance with applicable regulations. Each of these risks, if realized, could delay our clinical trials, the approval, if any, of our potential drug candidates by the FDA and other regulatory authorities, or the commercialization of our drug candidates or could result in higher product costs or otherwise deprive us of potential product revenues.
Developments by competitors may render our products or technologies obsolete or non-competitive which would have a material adverse effect on our business, results of operations and financial condition.
We compete against fully integrated pharmaceutical companies and smaller companies that are collaborating with larger pharmaceutical companies, academic institutions, government agencies and other public and private research organizations. Our drug candidates will have to compete with existing therapies and therapies under development by our competitors. Our commercial opportunities may be reduced or eliminated if our competitors develop and market products that are less expensive, more effective or safer than our drug products. Other companies have drug candidates in various stages of preclinical or clinical development to treat diseases for which we are also seeking to develop drug products. Some of these potential competing drugs are further advanced in development than our drug candidates and may be commercialized earlier. See Business – Competition.
Most of our competitors, either alone or together with their collaborative partners, operate larger research and development programs, staff and facilities and have substantially greater financial resources than we do, as well as significantly greater experience in:
| ● | developing drugs; |
| ● | undertaking preclinical testing and human clinical trials; |
| ● | obtaining marketing approvals from the FDA and other regulatory authorities; |
40
| ● | formulating and manufacturing drugs; and |
| ● | launching, marketing and selling drugs. |
These organizations also compete with us to attract qualified personnel, acquisitions and joint ventures candidates and for other collaborations. Activities of our competitors may impose unanticipated costs on our business or adversely affect the market for our drug products which would have a material adverse effect on our business, results of operations and financial condition.
If we in-license drug candidates, we may delay or otherwise adversely affect the development of our existing drug candidates, which may negatively impact our business, results of operations and financial condition.
In addition to our own internally developed drug candidates, we proactively seek opportunities to in-license and advance other drug candidates that are strategic and have value-creating potential to take advantage of our development know-how and technology. In-licensing additional drug candidates may significantly increase our capital requirements, and place a strain on the time of our existing personnel, which may delay or otherwise adversely affect the development of our existing drug candidates or cause us to re-prioritize our drug pipeline if we do not have the necessary capital resources to develop all of our drug candidates, which may have a material adverse impact on our business, results of operations and financial condition.
If we are unable to manage future growth successfully there could be a material adverse impact on our business, results of operations and financial condition.
To manage our anticipated future growth, we must continue to implement and improve our managerial, operational and financial systems, expand our facilities and continue to recruit and train additional qualified personnel. The expansion of our operations may lead to significant costs and may divert our management and business development resources. Any inability on the part of our management to manage growth could delay the execution of our business plans or disrupt our operations. If we are unable to manage our growth effectively, we may not use our resources in an efficient manner, which may delay the development of our drug candidates and materially and adversely impact our business, results of operations and financial condition.
If we acquire companies, products or technologies, we may face integration risks and costs associated with those acquisitions that could negatively impact our business, results of operations and financial condition.
If we are presented with appropriate opportunities, we may acquire or make investments in complementary companies, products or technologies. If we acquire companies or technologies, we will face risks, uncertainties and disruptions associated with the integration process, including difficulties in the integration of the operations of an acquired company, integration of acquired technology with our products, diversion of our management’s attention from other business concerns, the potential loss of key employees or customers of the acquired business and impairment charges if future acquisitions are not as successful as we originally anticipate. In addition, our operating results may suffer because of acquisition-related costs or amortization expenses or charges relating to acquired intangible assets. Any failure to successfully integrate other companies, products or technologies that we may acquire may have a material adverse effect on our business and results of operations. Furthermore, we may have to incur debt or issue equity securities to pay for any additional future acquisitions or investments, the issuance of which could be dilutive to our existing stockholders.
We depend upon key employees and consultants in a competitive market for skilled personnel. If we are unable to attract and retain key personnel, it could adversely affect our ability to develop and market our products.
We are highly dependent upon the principal members of our management team, especially our President and Chief Executive Officer, Dror Bashan, as well as the Chairman of our Board of Directors, Zeev Bronfeld, our other directors, consultants and collaborating scientists. Many of these people have been involved with us for many years and have played integral roles in our progress, and we believe that they will continue to provide value to us. A loss of any of these personnel may have a material adverse effect on aspects of our business, clinical development and regulatory programs. We have employment agreements with Mr. Bashan and our other executive officers that may be terminated by us or the applicable officer at any time with varying notice periods of 60 to 180 days. The loss of any of these persons’ services
41
may adversely affect our ability to develop and market our products and obtain necessary regulatory approvals. Further, we do not maintain key-man life insurance.
We also depend in part on the continued service of our key scientific personnel and our ability to identify, hire and retain additional personnel. We experience intense competition for qualified personnel, and the existence of non-competition agreements between prospective employees and their former employers may prevent us from hiring those individuals or subject us to suit from their former employers. While we attempt to provide competitive compensation packages to attract and retain key personnel, many of our competitors are likely to have greater resources and more experience than we have, making it difficult for us to compete successfully for key personnel.
Our collaborations with outside scientists and consultants may be subject to restriction and change.
We work with medical experts, biologists, chemists and other scientists at academic and other institutions, and consultants who assist us in our research, development, regulatory and commercial efforts, including the members of our scientific advisory board. These scientists and consultants have provided, and we expect that they will continue to provide, valuable advice regarding our programs. These scientists and consultants are not our employees, may have other commitments that would limit their future availability to us and typically will not enter into non-compete agreements with us. If a conflict of interest arises between their work for us and their work for another entity, we may lose their services. In addition, we will be unable to prevent them from establishing competing businesses or developing competing products. For example, if a key scientist acting as a principal investigator in any of our clinical trials identifies a potential product or compound that is more scientifically interesting to his or her professional or academic interests, his or her availability to remain involved in our clinical trials could be restricted or eliminated, which may have a material adverse effect on our business, results of operations and financial condition.
Under current U.S. and Israeli law, we may not be able to enforce employees’ covenants not to compete and therefore may be unable to prevent our competitors from benefiting from the expertise of some of our former employees.
We have entered into non-competition agreements with substantially all of our employees. These agreements prohibit our employees, if they cease working for us, from competing directly with us or working for our competitors for a limited period. Under current U.S. and Israeli law, we may be unable to enforce these agreements against most of our employees and it may be difficult for us to restrict our competitors from gaining the expertise our former employees gained while working for us. If we cannot enforce our employees’ non-compete agreements, we may be unable to prevent our competitors from benefiting from the expertise of our former employees, which may have a material adverse effect on our business, results of operations and financial condition.
If we fail to maintain an effective system of internal control over financial reporting, we may not be able to accurately report our financial results or prevent fraud. As a result, stockholders could lose confidence in our financial and other public reporting, which would harm our business and the trading price of our common stock.
Effective internal control over financial reporting is necessary for us to provide reliable financial reports. Any failure to implement required new or improved controls, or difficulties encountered in their implementation could cause us to fail to meet our reporting obligations. While our assessment of our internal control over financial reporting resulted in our conclusion that as of December 31, 2021, our internal control over financial reporting was effective, we cannot predict the outcome of our testing or any subsequent testing by our auditor in future periods. Any testing by us conducted in connection with Section 404 of the Sarbanes-Oxley Act, or Section 404, or any subsequent testing by our independent registered public accounting firm, may reveal deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses or that may require prospective or retroactive changes to our financial statements or identify other areas for further attention or improvement. Inferior internal controls could also cause investors to lose confidence in our reported financial information and affect our reputation, which could have an adverse effect on the trading price of our common stock.
Our management is required to assess the effectiveness of our internal controls and procedures and disclose changes in these controls on an annual basis. However, for as long as we are a non accelerated filer, our independent registered public accounting firm will not be required to attest to the effectiveness of our internal controls over financial reporting
42
pursuant to Section 404. An independent assessment of the effectiveness of our internal controls could identify deficiencies in internal controls over financial reporting that our management’s assessment might not. Undetected material weaknesses in our internal controls could lead to financial statement restatements and require us to incur the expense of remediation.
Our internal computer systems, or those used by our third-party contractors or consultants, may fail or suffer security breaches.
Despite the implementation of security measures, our internal computer systems and those of our present and future contractors and consultants are vulnerable to damage from computer viruses and unauthorized access. Although to our knowledge we have not experienced any material system failure or security breach to date, if such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our development programs and our business operations. For example, the loss of clinical trial data from completed or future clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Likewise, we rely on our third-party research institution collaborators for research and development of our product candidates and other third parties for the manufacture of our product candidates and to conduct clinical trials, and similar events relating to their computer systems could also have a material adverse effect on our business. We have a cybersecurity insurance policy to protect us from such risks. However, to the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriate disclosure of confidential or proprietary information, we could incur liability despite our insurance policy, and the further development and commercialization of our product candidates could be delayed.
We could be subject to securities class action litigation.
Securities class action litigation is often brought against a company following a period of volatility or decline in the market price of its securities. As with pharmaceutical companies generally, our company has experienced significant stock price volatility in recent years. If we become subject to such litigation, we will face substantial costs and a diversion of management’s attention and resources, which could have a material adverse effect on our business, results of operation and financial condition.
If product liability claims are brought against us, it may result in reduced demand for our products and product candidates or damages that exceed our insurance coverage.
The clinical testing, marketing and use of our products and product candidates exposes us to product liability claims if the use or misuse of those products or product candidates cause injury or disease, or results in adverse effects. Use of our products or product candidates, whether in clinical trials or post approval, could result in product liability claims. We presently carry clinical trial liability insurance with coverages of up to $10.0 million per occurrence and $10.0 million in the aggregate, an amount we consider reasonable and customary. However, this insurance coverage includes various deductibles, limitations and exclusions from coverage, and in any event might not fully cover any potential claims. We may need to obtain additional clinical trial liability coverage prior to initiating additional clinical trials. We expect to obtain product liability insurance coverage before commercialization of our product candidates; however, such insurance is expensive and insurance companies may not issue this type of insurance when we need it. We may not be able to obtain adequate insurance in the future at an acceptable cost. Any product liability claim, even one that was not in excess of our insurance coverage or one that is meritless and/or unsuccessful, may adversely affect our cash available for other purposes, such as research and development, which may have a material adverse effect on our business, results of operations and financial condition. Product liability claims, even if without merit, may result in reduced demand for our products, if approved, or result in adverse market reactions, which would have a material adverse effect on our business, results of operations and financial condition.
Reforms in the healthcare industry and the uncertainty associated with pharmaceutical pricing, reimbursement and related matters could adversely affect the marketing, pricing and demand for our products, if approved.
Increasing healthcare expenditures have been the subject of considerable public attention in the United States. Both private and government entities are seeking ways to reduce or contain healthcare costs. Numerous proposals that would result in changes in the U.S. healthcare system are continuously introduced or proposed in the U.S. Congress and in
43
some state legislatures within the United States, including reductions in the pricing of prescription products and changes in the levels at which consumers and healthcare providers are reimbursed for purchases of pharmaceutical products. Legislation and regulations that reduce reimbursement for our product candidates could adversely impact how much or under what circumstances healthcare providers will prescribe or administer our product candidates, if approved. This could materially and adversely impact our business by reducing our ability to generate revenue, raise capital, obtain additional collaborators and market our products, if approved. In addition, we believe the increasing emphasis on managed care in the United States has and will continue to put pressure on the price and usage of pharmaceutical products, which may adversely impact product sales, upon approval, if at all.
Governments outside the United States tend to impose strict price controls and reimbursement approval policies, which may adversely affect our prospects for generating revenue.
In some countries, particularly European Union member states, the pricing of prescription pharmaceuticals is subject to governmental control. In these countries, pricing negotiations with governmental authorities can take considerable time (six to 12 months or longer) after the receipt of marketing approval for a product. To obtain reimbursement or pricing approval in some countries with respect to any product candidate that achieves regulatory approval, we may be required to conduct a clinical trial that compares the cost-effectiveness of our product candidate to other available therapies. Any unavailability or limitation on the reimbursement of our products upon approval, if at all, or the determination of unsatisfactory reimbursement prices, may have a material adverse effect on our business, results of operations and financial condition. Further, if we achieve regulatory approval of any product, we must successfully negotiate product pricing for such product in individual countries. As a result, the pricing of our product candidates, if approved, in different countries may vary widely, thus creating the potential for third-party trade in our products in an attempt to exploit price differences between countries. This third-party trade of our products could undermine our sales in markets with higher prices which could have a material adverse effect on our business, results of operations and financial condition.
Our ability to utilize net operating loss carryforwards may be limited.
Our NOL carryforwards as of December 31, 2021, are equal to approximately $247.9 million, of which approximately $36.1 million may be restricted under Section 382 of the Internal Revenue Code, or the IRC. IRC Section 382 applies whenever a corporation with NOLs experiences an ownership change. As a result of IRC Section 382, the taxable income for any post-change year that may be offset by a pre-change NOL may not exceed the fair market value of the pre-change entity multiplied by the IRC long-term tax exempt rate. Significant judgment is required in determining any valuation allowance recorded against deferred tax assets. In assessing the need for a valuation allowance, we considered all available evidence, including past operating results, the most recent projections for taxable income and prudent and feasible tax planning strategies. We reassess our valuation allowance periodically and if future evidence allows for a partial or full release of the valuation allowance, a tax benefit will be recorded accordingly. Any ownership change (including as a result of conversion of our outstanding convertible notes into shares of our common stock), or any other limitation on our utilization of NOLs, could have a material adverse effect on our business, results of operations and financial condition.
Our corporate structure may create U.S. federal income tax inefficiencies.
Protalix Ltd. is our wholly-owned subsidiary and thus a controlled foreign corporation of our company for U.S. federal income tax purposes. This organizational structure may create inefficiencies, as certain types of income and investments of Protalix Ltd. that otherwise would not be currently taxable under general U.S. federal income tax principles may become taxable. These inefficiencies may require us to use more of our NOLs than we otherwise might and may result in a tax liability without a corresponding distribution from our subsidiary which could have a material adverse effect on our business, results of operations and financial condition.
We are a holding company with no operations of our own.
We are a holding company with no operations of our own. Accordingly, our ability to conduct our operations, service any debt that we may incur in the future and pay dividends, if any, is dependent upon the earnings from the business conducted by Protalix Ltd. The distribution of those earnings or advances or other distributions of funds by our
44
subsidiary to us, as well as our receipt of such funds, are contingent upon the earnings of Protalix Ltd. and are subject to various business considerations and U.S. and Israeli law. If Protalix Ltd. is unable to make sufficient distributions or advances to us, or if there are limitations on our ability to receive such distributions or advances, we may not have the cash resources necessary to conduct our corporate operations or service our debt which would have a material adverse effect on our business, results of operations and financial condition.
Risks Related to our Financial Condition and Capital Requirements
Servicing our debt and settling conversion requests may require a significant amount of cash, and we may not have sufficient cash flow from our business to pay our debt. Furthermore, restrictive covenants governing our indebtedness may restrict our ability to raise additional capital.
We currently have outstanding $28.75 million aggregate principal amount of our 2024 Notes which are secured with a perfected lien on all of our assets. Under the terms of the indenture governing the 2024 Notes, or the 2024 Indenture, we are required to maintain a minimum cash balance of at least $7.5 million. Our ability to make payments with respect to the 2024 Notes and to satisfy any other debt obligations depends on our future operating performance and our ability to generate significant cash flow in the future, which will be affected by prevailing economic conditions and financial, business, competitive, legislative and regulatory factors as well as other factors affecting our company and industry, many of which are beyond our control. If, when required, we are unable to comply with the terms of the 2024 Notes, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. In addition, certain terms of the 2024 regarding the security interest or future indebtedness may restrict us from adopting any of these alternatives. We may be unable to obtain amendments and waivers of such restrictions. If there is a default of such notes, the note holders could, among other things, elect to declare all amounts owed immediately due and payable, which could cause all or a large portion of our available cash flow to be used to pay such amounts and thereby reduce the amount of cash available to pursue our business plans or force us into bankruptcy or liquidation, or, with respect to our indebtedness that is secured, result in the foreclosure on the assets that secure the debt, which would force us to relinquish rights to assets that we may believe are critical to our business. Any default on our debt will have a material adverse effect on our business, results of operations and financial condition.
Our significant level of indebtedness could adversely affect our business, results of operations and financial condition and prevent us from fulfilling our obligations under our convertible notes and our other indebtedness.
Our 2024 Notes represent a significant amount of indebtedness with substantial debt service requirements. We may also incur additional indebtedness to meet future financing needs. Our substantial indebtedness could have material adverse effects on our business, results of operations and financial condition. For example, it could:
| ● | make it more difficult for us to satisfy our financial obligations, including with respect to the convertible notes; |
| ● | result in an event of default under our outstanding convertible notes if we fail to comply with the financial and other restrictive covenants contained in agreements governing any future indebtedness, which event of default could result in all of our debt becoming immediately due and payable; |
| ● | increase our vulnerability to general adverse economic, industry and competitive conditions; |
| ● | reduce the availability of our cash flow to fund working capital, capital expenditures, acquisitions and other general corporate purposes because we will be required to dedicate a substantial portion of our cash flow from operations to the payment of principal and interest on our indebtedness; |
| ● | limit our flexibility in planning for, or reacting to, and increasing our vulnerability to changes in our business, the industry in which we operate and the general economy; |
45
| ● | prevent us from raising funds necessary to purchase convertible notes surrendered to us by holders upon a fundamental change (as described in the 2024 Indenture governing the notes), which failure would result in an event of default with respect to the convertible notes; |
| ● | place us at a competitive disadvantage compared to our competitors that have less indebtedness or are less highly leveraged and that, therefore, may be able to take advantage of opportunities that our debt levels or leverage prevent us from exploiting; and |
| ● | limit our ability to obtain additional financing. |
Each of these factors may have a material and adverse effect on our business, results of operations and financial condition and our ability to meet our payment obligations under the convertible notes and our other indebtedness.
We are required to comply with a number of covenants under the 2024 Indenture governing our outstanding convertible notes that could hinder our growth.
The 2024 Indenture contains a number of restrictive affirmative and negative covenants, which limit our ability to incur additional debt; exceed certain limits; pay dividends or distributions; or merge, consolidate or dispose of substantially all of our assets, including all of our intellectual property assets and other material assets securing such convertible notes. A breach of these covenants could result in default, and if such default is not cured or waived, the holders of the indebtedness could, among other things, elect to declare all amounts owed immediately due and payable, which could cause all or a large portion of our available cash flow to be used to pay such amounts and thereby reduce the amount of cash available to pursue our business plans or force us into bankruptcy or liquidation, or, result in the foreclosure on the assets that secure the debt, including all of our intellectual property assets, which would force us to relinquish rights to such assets that we may believe are critical to our business. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations. Any default on our debt will have a material adverse effect on our business, results of operations and financial condition.
Any conversion of our outstanding convertible notes into common stock will dilute the ownership interest of our existing stockholders, including holders who had previously converted their notes.
The conversion of some or all of our convertible notes into shares of our common stock will dilute the ownership interests of our existing stockholders. Any sales in the public market of our common stock issuable upon such conversion could adversely affect prevailing market prices of our common stock. In addition, the existence of our outstanding convertible notes may encourage short selling by market participants because the conversion of convertible notes could depress the market price of our common stock.
The fundamental change purchase feature of our outstanding convertible notes may delay or prevent an otherwise beneficial attempt to take over our company.
The terms of our outstanding convertible notes require us to offer to purchase the notes for cash in the event of a fundamental change. A non-stock takeover of our company may trigger the requirement that we purchase the notes. This feature may have the effect of delaying or preventing a takeover of our company that would otherwise be beneficial to our stockholders.
We may fail to meet the continued market capitalization-based listing requirement or other continued listing requirements of The NYSE American.
The stock market in general, and the market for pharmaceutical companies in particular, have experienced extreme price and volume fluctuations that may have been unrelated or disproportionate to the operating performance of the listed companies. The trading price of our common stock has been volatile and has been subject to wide price fluctuations in response to various factors, many of which are beyond our control. The volatility of our stock price has from time to time in recent periods affected our market capitalization. Adverse fluctuations in the price per share of our common stock or our market capitalization may result in our failure to meet the continued listing requirements of The NYSE American, which would require us to take steps to gain compliance with alternate listing standards or take remedial steps to bring us into compliance. A failure to maintain or regain compliance with applicable listing standards could adversely
46
affect the liquidity of our common stock and could result in an event of default under the 2024 Indenture, which would have a material adverse effect on our business, results of operations and financial condition.
We currently have no significant product revenues and need to raise additional capital to operate our business, which may not be available on favorable terms, or at all, and which will have a dilutive effect on our stockholders.
To date, we have not generated significant revenues from product sales and only minimal revenues from research and development services and other fees, other than the milestone and other payments we have received in connection with our agreements with Pfizer and Chiesi. For the years ended December 31, 2021, 2020 and 2019, we had net losses from continuing operations of $27.6 million, $6.5 million and $18.3 million, respectively, primarily as a result of expenses incurred through a combination of research and development activities and expenses supporting those activities, which includes share-based compensation expense. Drug development and commercialization is very capital intensive. We fund all of our operations and capital expenditures from the revenues we generate from licensing fees and grants, the net proceeds of equity and debt offerings and other sources. In addition, changes may occur that could consume our existing capital at a faster rate than projected, including, among others, the cost and timing of regulatory approvals, changes in the progress of our research and development efforts and the costs of protecting our intellectual property rights.
We will need to finance our future cash needs through corporate collaboration, licensing or similar arrangements, public or private equity offerings or debt financings. If we are unable to secure additional financing in the future on acceptable terms, or at all, we may be unable to commence or complete planned preclinical and clinical trials or obtain approval of our drug candidates from the FDA and other regulatory authorities. In addition, we may be forced to reduce or discontinue product development or product licensing, reduce or forego sales and marketing efforts and other commercialization activities or forego attractive business opportunities in order to improve our liquidity and to enable us to continue operations which would have a material adverse effect on our business and results of operations. Furthermore, any additional source of financing will likely involve the issuance of our equity securities, which will have a dilutive effect on our stockholders.
We are not currently profitable and delays in achieving profitability, if at all, will have a material adverse effect on our business and results of operations and could negatively impact the value of our common stock.
We may incur losses for the foreseeable future. We expect to continue to incur significant operating expenditures, and we anticipate that our expenses will increase in the foreseeable future as we:
| ● | continue to undertake preclinical development and clinical trials for our current and new drug candidates; |
| ● | seek regulatory approvals for our drug candidates; and |
| ● | seek to in-license additional technologies. |
We also may continue to experience negative cash flow for the foreseeable future as we fund our operating losses and capital expenditures. As a result, we will need to generate significant revenues in order to achieve and maintain profitability. We may not be able to generate these revenues or achieve profitability in the foreseeable future, if at all. Delays in achieving profitability, or subsequent failures to maintain profitability, will have a material adverse effect on our business and results of operations and could negatively impact the value of our common stock.
Risks Related to the Commercialization of Drug Products
There has been continued non-compliance with the terms and conditions of the Brazil Agreement.
We do not control and may not be able to effectively influence Fiocruz’s ability to distribute BioManguinhos alfataliglicerase in Brazil. Any failure by Fiocruz to comply with the purchase requirements of the Brazil Agreement, or any other material breach by Fiocruz of the agreement, may have a material adverse effect on our business, results of operations and financial condition.
We face the risk of lower than anticipated purchases of BioManguinhos alfataliglicerase by the Brazilian MoH. In addition, we may fail to supply the intended amounts on time, if at all. We also cannot accurately predict the amount of
47
revenues we will generate under the Brazil Agreement in future periods, if any. Any failure by the Brazilian MoH to purchase BioManguinhos alfataliglicerase, by us to supply BioManguinhos alfataliglicerase for purchase or by Fiocruz to distribute BioManguinhos alfataliglicerase in Brazil, or the experience of significant delays in any of the foregoing, may have a material adverse effect on our business, results of operations and financial condition.
We have limited experience in selling, marketing or distributing products and limited internal capability to do so.
We currently have very limited sales, marketing or distribution capabilities and no experience in building a sales force and distribution capabilities. Under our arrangements with Pfizer and Chiesi, we have out-licensed the marketing rights to Elelyso, pegunigalsidase alfa and alidornase alfa via inhalation, except that we retained the marketing rights to BioManguinhos alfataliglicerase in Brazil. We have not licensed the marketing or commercialization rights to any of our other product candidates to any party. The commercialization of a drug product requires that we commit significant financial and managerial resources to develop a marketing and sales force with technical expertise and with supporting distribution capabilities. Factors that may inhibit our efforts to commercialize our products directly and without strategic partners include:
| ● | the inability to recruit and retain adequate numbers of effective sales and marketing personnel; |
| ● | the inability of sales personnel to obtain access to an adequate numbers of physicians or to pursuance them to prescribe our products; |
| ● | the lack of complementary products to be offered by sales personnel, which may put us at a competitive disadvantage relative to companies with more extensive product lines; and |
| ● | unforeseen costs and expenses associated with creating and sustaining an independent sales and marketing organization. |
We may not be successful in recruiting or retaining the sales and marketing personnel necessary to sell BioManguinhos alfataliglicerase or any of our products upon approval, if at all, which would have a material adverse effect on our business, results of operations and financial condition.
We may enter into distribution arrangements and marketing alliances for certain products and any failure to successfully identify and implement these arrangements on favorable terms, if at all, may impair our ability to commercialize our product candidates.
We may need to establish a sales force to market one or more of our product candidates, if approved. We do not anticipate having the resources in the foreseeable future to develop global sales and marketing capabilities for all of the products we are developing. We may elect to pursue arrangements regarding the sales and marketing and distribution of one or more of our product candidates, and our future revenues may depend, in part, on our ability to enter into and maintain arrangements with other companies having sales, marketing and distribution capabilities and the ability of such companies to successfully market and sell any such products. Any failure to enter into such arrangements and marketing alliances on favorable terms, if at all, could delay or impair our ability to commercialize our product candidates and could increase our costs of commercialization. Any use of distribution arrangements and marketing alliances to commercialize our product candidates will subject us to a number of risks, including the following:
| ● | we may be required to relinquish important rights to our products or product candidates; |
| ● | we may not be able to control the amount and timing of resources that our distributors or collaborators may devote to the commercialization of our product candidates; |
| ● | our distributors or collaborators may experience financial difficulties; |
| ● | our distributors or collaborators may not devote sufficient time to the marketing and sales of our products; and |
48
| ● | business combinations or significant changes in a collaborator’s business strategy may adversely affect a collaborator’s willingness or ability to complete its obligations under any arrangement. |
We may need to enter into additional co-promotion arrangements with third parties where our own sales force is neither well situated nor large enough to achieve maximum penetration in the market. We may not be successful in entering into any co-promotion arrangements, and the terms of any co-promotion arrangements we enter into may not be favorable to us.
If physicians, patients, third party payors and others in the medical community do not accept and use taliglucerase alfa, or any of our other product candidates, if approved, our ability to generate revenue from product sales will be materially impaired.
Physicians and patients, and other healthcare providers, may not accept and use any of our products or any product candidates, if approved for marketing. Future acceptance and use of any of our products or any product candidates, if approved, will depend upon a number of factors including:
| ● | perceptions by physicians, patients, third party payors and others in the medical community about the safety and effectiveness of taliglucerase alfa or our other drug candidates; |
| ● | the willingness of the target patient population to try new therapies and of physicians to prescribe these therapies; |
| ● | the prevalence and severity of any side effects, including any limitations or warnings contained in our products’ approved labeling; |
| ● | pharmacological benefits of taliglucerase alfa or our other drug candidates relative to competing products and products under development; |
| ● | the efficacy and potential advantages relative to competing products and products under development; |
| ● | relative convenience and ease of administration; |
| ● | effectiveness of education, marketing and distribution efforts by us and our licensees and distributors, if any; |
| ● | publicity concerning taliglucerase alfa or our other drug candidates or competing products and treatments; |
| ● | coverage and reimbursement of our products by third party payors; and |
| ● | the price for our products and competing products. |
A lack of market acceptance of BioManguinhos alfataliglicerase in Brazil, or globally for any of our other products candidates, if approved, would have a material adverse effect on our business, results of operations and financial condition.
If the market opportunities for other product candidates, and for BioManguinhos alfataliglicerase in Brazil, are smaller than we believe they are, our revenues may be adversely affected and our business may suffer.
To date, our development efforts have focused mainly on relatively rare disorders with small patient populations, in particular Gaucher disease and Fabry disease. Currently, most reported estimates of the prevalence of these diseases are based on studies of small subsets of the population of specific geographic areas, which are then extrapolated to estimate the prevalence of the diseases in the broader world population. As new studies are performed, the estimated prevalence of these diseases may change. There can be no assurance that the prevalence of Gaucher disease or Fabry disease in the study populations, particularly in these newer studies, accurately reflect the prevalence of these diseases in the broader world population. If the market opportunities for our current product candidates are smaller than we believe they are, our revenues may be adversely affected and our business may suffer.
49
Coverage and reimbursement may not be available for one or more of our product candidates, if approved, in all territories, which could diminish our sales or affect our ability to sell any such products profitably.
Market acceptance and sales of any one or more of our product candidates, if approved, will depend on coverage and reimbursement policies in the countries in which they are approved for sale. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which drugs they will pay for and establish reimbursement levels. Obtaining reimbursement approval for an approved product from governments and other third party payors is a time consuming and costly process that requires our collaborators or us, as the case may be, to provide supporting scientific, clinical and cost-effectiveness data for the use of our products, if and when approved, to every payor. We may not be able to provide data sufficient to gain acceptance with respect to coverage and reimbursement or we might need to conduct post-marketing studies in order to demonstrate the cost-effectiveness of approved products, if any, to such payors’ satisfaction. Such studies might require our collaborators or us to commit a significant amount of management time and financial and other resources. Even if a payor determines that an approved product is eligible for reimbursement, the payor may impose coverage limitations that preclude payment for some uses that are approved by the FDA or other regulatory authorities. In addition, full reimbursement may not be available for high priced products. Moreover, eligibility for coverage does not imply that any approved product will be reimbursed in all cases or at a rate that allows us to make a profit or even cover our costs. Limited reimbursement amounts may reduce the demand for, or the price of, our product candidates. If coverage and reimbursement are not available or are available only to limited levels, the sales of our products, if approved, may be diminished or we may not be able to sell such products profitably.
We and our collaborating partners may be subject, directly or indirectly, to federal and state healthcare fraud and abuse and false claims laws and regulations. If we or our collaborating partners are unable to comply, or have not fully complied, with such laws, we could face substantial penalties.
All marketing activities associated with drug products that are approved for sale in the United States, if any, will be, directly or indirectly through our customers, subject to numerous federal and state laws governing the marketing and promotion of pharmaceutical products in the United States, including, without limitation, the federal Anti-Kickback Law, the federal False Claims Act and HIPAA. These laws may adversely impact, among other things, our proposed sales, marketing and education programs.
The federal Anti-Kickback Law prohibits persons from knowingly and willfully soliciting, receiving, offering or paying remuneration, directly or indirectly, to induce either the referral of an individual, or the furnishing, recommending, or arranging for a good or service, for which payment may be made under a federal healthcare program, such as the Medicare and Medicaid programs. The term “remuneration” has been broadly interpreted to include anything of value, including for example, gifts, discounts, the furnishing of supplies or equipment, credit arrangements, payments of cash, waivers of co-payments and deductibles, ownership interests and providing anything at less than its fair market value. Despite a series of narrow safe harbors, the federal Anti-Kickback Law prohibits many arrangements and practices that are lawful in businesses outside of the healthcare industry. Penalties for violations of the federal Anti-Kickback Law include criminal penalties and civil sanctions such as fines, imprisonment and possible exclusion from Medicare, Medicaid and other state or federal healthcare programs. Many states have also adopted laws similar to the federal Anti-Kickback Law, some of which apply to the referral of patients for healthcare items or services reimbursed by any source, not only the Medicare and Medicaid programs, and do not contain identical safe harbors.
The federal False Claims Act imposes liability on any person who, among other things, knowingly presents, or causes to be presented, a false or fraudulent claim for payment by a federal healthcare program. In addition, various states have enacted false claims laws analogous to the False Claims Act. Many of these state laws apply where a claim is submitted to any third-party payer and not merely a federal healthcare program. Violations of the federal False Claims Act and the analogous state laws may result in substantial financial penalties, some as much as three times the actual damages sustained by the government.
HIPAA created several new federal crimes, including health care fraud, and false statements relating to health care matters. The health care fraud statute prohibits knowingly and willfully executing a scheme to defraud any health care benefit program, including private third-party payers. The false statements statute prohibits knowingly and willfully
50
falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for health care benefits, items or services.
We are unable to predict whether we could be subject to actions under any of these or other fraud and abuse laws, or the impact of such actions. Moreover, to the extent that taliglucerase alfa or any of our product candidates, if approved for marketing, will be sold in a foreign country, we and our future collaborators may be subject to similar foreign laws and regulations. If we or any of our future collaborators are found to be in violation of any of the laws described above and other applicable state and federal fraud and abuse laws, we may be subject to penalties, including civil and criminal penalties, damages, fines, exclusion from government healthcare reimbursement programs and the curtailment or restructuring or our operations, any of which could have a material adverse effect on our business, results of operations and financial condition.
Risks Related to Intellectual Property Matters
The intellectual property and assets owned by our subsidiaries are subject to security agreements that secure our payment and other obligations under our convertible notes, and our subsidiaries have guaranteed all of those obligations.
In connection with the issuance of our 2024 Notes, we entered into new security agreements pursuant to which our subsidiaries provided first priority security interests in all of their assets, which consist of all of our intellectual property and other material assets. The security agreements secure certain payment, indemnification and other obligations under the 2024 Notes. If we were to default on certain of our obligations, or in certain other circumstances generally related to a bankruptcy or insolvency, holders of our outstanding 2024 Notes could seek to foreclose on the collateral under the security agreements to obtain satisfaction of our obligations, and our business could be materially and adversely impacted, which would in turn have a material adverse effect on our results of operations and financial condition.
Furthermore, in connection with the issuance of the 2024 Notes, our subsidiaries guaranteed all of our obligations under the 2024 Indenture. If we were to default on our obligations under the 2024 Indenture, the holders could require our subsidiaries to satisfy all of those obligations under the guarantees.
If we fail to adequately protect or enforce our intellectual property rights or secure rights to third party patents, the value of our intellectual property rights would diminish and our business, competitive position and results of operations would suffer.
As of December 31, 2021, we had more than 30 pending patent applications. However, the filing of a patent application does not mean that we will be issued a patent, or that any patent eventually issued will be as broad as requested in the patent application or sufficient to protect our technology. Any modification required to a current patent application may delay the approval of such patent application which would have a material adverse effect on our business, results of operations and financial condition. In addition, there are a number of factors that could cause our patents, if granted, to become invalid or unenforceable or that could cause our patent applications to not be granted, including known or unknown prior art, deficiencies in the patent application or the lack of originality of the technology. Our competitive position and future revenues will depend in part on our ability and the ability of our licensors and collaborators to obtain and maintain patent protection for our products, methods, processes and other technologies, to preserve our trade secrets, to prevent third parties from infringing on our proprietary rights and to operate without infringing the proprietary rights of third parties. We have filed U.S. and international patent applications for process patents, as well as composition of matter patents, for taliglucerase alfa and our product candidates. However, we cannot predict:
| ● | the degree and range of protection any patents will afford us against competitors and those who infringe upon our patents, including whether third parties will find ways to invalidate or otherwise circumvent our licensed patents; |
| ● | if and when patents will issue; |
| ● | whether or not others will obtain patents claiming aspects similar to those covered by our licensed patents and patent applications; or |
51
| ● | whether we will need to initiate litigation or administrative proceedings, which may be costly, whether we win or lose. |
As of December 31, 2021, we held, or had license rights to, more than 80 patents. If patent rights covering our products or technologies are not sufficiently broad, they may not provide us with sufficient proprietary protection or competitive advantages against competitors with similar products and technologies. Furthermore, if the USPTO or foreign patent offices issue patents to us or our licensors, others may challenge the patents or circumvent the patents, or the patent office or the courts may invalidate the patents. Thus, any patents we own or license from or to third parties may not provide any protection against our competitors and those who infringe upon our patents.
Furthermore, the life of our patents is limited. The patents we hold, and the patents that may be issued in the future based on patent applications from the patent families, relating to our ProCellEx protein expression system are expected to expire by 2025.
We rely on confidentiality agreements that could be breached and may be difficult to enforce which could have a material adverse effect on our business and competitive position.
Our policy is to enter agreements relating to the non-disclosure of confidential information with third parties, including our contractors, consultants, advisors and research collaborators, as well as agreements that purport to require the disclosure and assignment to us of the rights to the ideas, developments, discoveries and inventions of our employees and consultants while we employ them. However, these agreements can be difficult and costly to enforce. Moreover, to the extent that our contractors, consultants, advisors and research collaborators apply or independently develop intellectual property in connection with any of our projects, disputes may arise as to the proprietary rights to the intellectual property. If a dispute arises, a court may determine that the right belongs to a third party, and enforcement of our rights can be costly and unpredictable. In addition, we rely on trade secrets and proprietary know-how that we seek to protect in part by confidentiality agreements with our employees, contractors, consultants, advisors and others. Despite the protective measures we employ, we still face the risk that:
| ● | these agreements may be breached; |
| ● | these agreements may not provide adequate remedies for the applicable type of breach; or |
| ● | our trade secrets or proprietary know-how will otherwise become known. |
Any breach of our confidentiality agreements or our failure to effectively enforce such agreements may have a material adverse effect on our business and competitive position.
If we infringe the rights of third parties we could be prevented from selling products, forced to pay damages and required to defend against litigation which could result in substantial costs and may have a material adverse effect on our business, results of operations and financial condition.
We have not received to date any claims of infringement by any third parties. However, as our drug candidates progress into clinical trials and commercialization, if at all, our public profile and that of our drug candidates may be raised and generate such claims. Defending against such claims, and occurrence of a judgment adverse to us, could result in unanticipated costs and may have a material adverse effect on our business and competitive position. If our products, methods, processes and other technologies infringe the proprietary rights of other parties, we may incur substantial costs and we may have to:
| ● | obtain licenses, which may not be available on commercially reasonable terms, if at all; |
| ● | redesign our products or processes to avoid infringement; |
| ● | stop using the subject matter claimed in the patents held by others, which could cause us to lose the use of one or more of our drug candidates; |
52
| ● | defend litigation or administrative proceedings that may be costly whether we win or lose, and which could result in a substantial diversion of management resources; or |
| ● | pay damages. |
Any costs incurred in connection with such events or the inability to sell our products may have a material adverse effect on our business, results of operations and financial condition.
If we cannot meet requirements under our license agreements, we could lose the rights to our products, which could have a material adverse effect on our business.
We depend on licensing agreements with third parties to maintain the intellectual property rights to certain of our product candidates. Our license agreements require us to make payments and satisfy performance obligations in order to maintain our rights under these agreements. All of these agreements last either throughout the life of the patents that are the subject of the agreements, or with respect to other licensed technology, for a number of years after the first commercial sale of the relevant product.
In addition, we are responsible for the cost of filing and prosecuting certain patent applications and maintaining certain issued patents licensed to us. If we do not meet our obligations under our license agreements in a timely manner, we could lose the rights to our proprietary technology which could have a material adverse effect on our business, results of operations and financial condition.
Risks Relating to our Operations in Israel
Potential political, economic and military instability in the State of Israel, where the majority of our senior management and our research and development facilities are located, may adversely affect our results of operations.
Our executive office and operations are located in the State of Israel. Accordingly, political, economic and military conditions in Israel directly affect our business. Since the State of Israel was established in 1948, a number of armed conflicts have occurred between Israel and its Arab neighbors. Any hostilities involving Israel or the interruption or curtailment of trade between Israel and its present trading partners, or a significant downturn in the economic or financial condition of Israel, could affect adversely our operations and product development. Although Israel has entered into various agreements with Egypt, Jordan and the Palestinian Authority, Israel periodically experiences an increase in unrest and terrorist activity. The establishment in 2006 of a government in the Gaza Strip by representatives of the Hamas militant group has created additional unrest and uncertainty in the region. Our facilities in northern Israel are in range of rockets that were fired from Lebanon into Israel during a 2006 war with the Hizbollah in Lebanon, and suffered minimal damages during one of the rocket attacks. Our insurance policies do not cover us for the damages incurred in connection with these conflicts or for any resulting disruption in our operations. The Israeli government, as a matter of law, provides coverage for the reinstatement value of direct damages that are caused by terrorist attacks or acts of war; however, the government may cease providing such coverage or the coverage might not be enough to cover potential damages. If our facilities are damaged as a result of hostile action, our operations may be materially adversely affected.
There is currently a civil war in Syria, also bordering Israel, and Israel has been hit by rockets and mortars originating from Syria. The ultimate effect of these developments on the political and security situation in the Middle East and on Israel’s position within the region is not clear at this time.
Our operations may be disrupted by the obligations of our personnel to perform military service which could have a material adverse effect on our business.
Many of our male employees in Israel, including members of senior management, are obligated to perform up to one month (in some cases more) of annual military reserve duty until they reach the age of 45 and, in the event of a military conflict, could be called to active duty. Our operations could be disrupted by the absence of a significant number of our employees related to military service or the absence for extended periods of military service of one or more of our key employees. A disruption may have a material adverse effect on our business, results of operations and financial condition.
53
Because a certain portion of our expenses is incurred in New Israeli Shekels, our results of operations may be seriously harmed by currency fluctuations and inflation.
We report our financial statements in U.S. dollars, our functional currency. Although most of our expenses are incurred in U.S. dollars, we pay a portion of our expenses in New Israeli Shekels, or NIS, and as a result, we are exposed to risk to the extent that the inflation rate in Israel exceeds the rate of devaluation of the NIS in relation to the U.S. dollar or if the timing of these devaluations lags behind inflation in Israel. In that event, the U.S. dollar cost of our operations in Israel will increase and our U.S. dollar-measured results of operations will be adversely affected. To the extent that the value of the NIS increases against the U.S. dollar, our expenses on a dollar cost basis increase. Our operations also could be adversely affected if we are unable to guard against currency fluctuations in the future. To date, we have not engaged in hedging transactions. In the future, we may enter into currency hedging transactions to decrease the risk of financial exposure from fluctuations in the exchange rate of the U.S dollar against the NIS. These measures, however, may not adequately protect us from material adverse effects.
The tax benefits available to us require that we meet several conditions and may be terminated or reduced in the future, which would increase our taxes.
We are able to take advantage of tax exemptions and reductions resulting from the “Approved Enterprise” status of our facilities in Israel. To remain eligible for these tax benefits, we must continue to meet certain conditions, including making specified investments in property and equipment, and financing at least 30% of such investments with share capital. If we fail to meet these conditions in the future, the tax benefits would be canceled and we may be required to refund any tax benefits we already have enjoyed. These tax benefits are subject to investment policy by the Investment Center and may not be continued in the future at their current levels or at any level. In recent years the Israeli government has reduced the benefits available and has indicated that it may further reduce or eliminate some of these benefits in the future. The termination or reduction of these tax benefits or our inability to qualify for additional “Approved Enterprise” approvals may increase our tax expenses in the future, which would reduce our expected profits and adversely affect our business and results of operations. Additionally, if we increase our activities outside of Israel, for example, by future acquisitions, such increased activities generally may not be eligible for inclusion in Israeli tax benefit programs.
The Israeli government grants we have received for certain research and development expenditures restrict our ability to manufacture products and transfer technologies outside of Israel and require us to satisfy specified conditions. If we fail to satisfy these conditions, we may be required to refund grants previously received together with interest and penalties which could have a material adverse effect on our business and results of operations.
In the past, our research and development efforts have been financed, in part, through grants that we have received from NATI. We, therefore, must comply with the requirements of the Research Law. Under the Research Law we are prohibited from manufacturing products developed using these grants outside of the State of Israel without special approvals, although the Research Law does enable companies to seek prior approval for conducting manufacturing activities outside of Israel without being subject to increased royalties. We may not receive the required approvals for any proposed transfer of manufacturing activities. Even if we do receive approval to manufacture products developed with government grants outside of Israel, we may be required to pay an increased total amount of royalties (possibly up to 300% of the grant amounts plus interest), depending on the manufacturing volume that is performed outside of Israel, as well as at a possibly increased royalty rate. This restriction may impair our ability to outsource manufacturing or engage in similar arrangements for those products or technologies.
Additionally, under the Research Law, Protalix Ltd. is prohibited from transferring NATI-financed technologies and related intellectual property rights outside of the State of Israel, except under limited circumstances and only with the approval of NATI Council or the Research Committee. Protalix Ltd. may not receive the required approvals for any proposed transfer and, if received, Protalix Ltd. may be required to pay NATI a portion of the consideration that it receives upon any sale of such technology by a non-Israeli entity. The scope of the support received, the royalties that Protalix Ltd. has already paid to NATI, the amount of time that has elapsed between the date on which the know-how was transferred and the date on which NATI grants were received and the sale price and the form of transaction will be taken into account in order to calculate the amount of the payment to NATI. Approval of the transfer of technology to residents of the State of Israel is required, and may be granted in specific circumstances only if the recipient abides by
54
the provisions of applicable laws, including the restrictions on the transfer of know-how and the obligation to pay royalties. No assurance can be made that approval to any such transfer, if requested, will be granted.
These restrictions may impair our ability to sell our technology assets or to outsource manufacturing outside of Israel. The restrictions will continue to apply for a certain period of time even after we have repaid the full amount of royalties payable for the grants. If we fail to satisfy the conditions of the Research Law, we may be required to refund certain grants previously received together with interest and penalties, and may become subject to criminal charges, any of which could have a material adverse effect on our business, results of operations and financial condition.
Investors may have difficulties enforcing a U.S. judgment, including judgments based upon the civil liability provisions of the U.S. federal securities laws against us, our executive officers and most of our directors or asserting U.S. securities laws claims in Israel.
Most of our directors and all of our executive officers are residents of Israel, and accordingly, most of their assets and our assets are located outside the United States. Service of process upon our non-U.S. resident directors and officers and enforcement of judgments obtained in the United States against us, some of our directors and executive officers may be difficult to obtain within the United States. We have been informed by our legal counsel in Israel that investors may find it difficult to assert claims under U.S. securities laws in original actions instituted in Israel or obtain a judgment based on the civil liability provisions of U.S. federal securities laws against us, our officers and our directors. Israeli courts may refuse to hear a claim based on a violation of U.S. securities laws against us or our officers and directors because Israel is not the most appropriate forum to bring such a claim. In addition, even if an Israeli court agrees to hear a claim, it may determine that Israeli law and not U.S. law is applicable to the claim. If U.S. law is found to be applicable, the content of applicable U.S. law must be proved as a fact which can be a time-consuming and costly process. Certain matters of procedure will also be governed by Israeli law. There is little binding case law in Israel addressing the matters described above.
Israeli courts might not enforce judgments rendered outside Israel which may make it difficult to collect on judgments rendered against us. Subject to certain time limitations, an Israeli court may declare a foreign civil judgment enforceable only if it finds that:
| ● | the judgment was rendered by a court which was, according to the laws of the state of the court, competent to render the judgment; |
| ● | the judgment may no longer be appealed; |
| ● | the obligation imposed by the judgment is enforceable according to the rules relating to the enforceability of judgments in Israel and the substance of the judgment is not contrary to public policy; and |
| ● | the judgment is executory in the state in which it was given. |
Even if these conditions are satisfied, an Israeli court will not enforce a foreign judgment if it was given in a state whose laws do not provide for the enforcement of judgments of Israeli courts (subject to exceptional cases) or if its enforcement is likely to prejudice the sovereignty or security of the State of Israel. An Israeli court also will not declare a foreign judgment enforceable if:
| ● | the judgment was obtained by fraud; |
| ● | there is a finding of lack of due process; |
| ● | the judgment was rendered by a court not competent to render it according to the laws of private international law in Israel; |
| ● | the judgment is at variance with another judgment that was given in the same matter between the same parties and that is still valid; or |
55
| ● | at the time the action was brought in the foreign court, a suit in the same matter and between the same parties was pending before a court or tribunal in Israel. |
Risks Related to Investing in our Common Stock
The market price of our common stock may fluctuate significantly.
The market price of our common stock has experienced significant volatility as a result of the recent announcement relating to the receipt of the CRL from the FDA regarding the BLA for PRX-102. The securities of life sciences companies often experience significant volatility in connection with clinical trial and regulatory announcements.
We anticipate that the market price of our common stock is likely to continue to fluctuate significantly in response to numerous factors, some of which are beyond our control, such as:
| ● | the timing of and any delays in anticipated marketing approvals for pegunigalsidase alfa; |
| ● | the results of our studies of pegunigalsidase alfa and the progress and results of the studies of our other product candidates; |
| ● | our sale of shares of our common stock under our ATM program, or market expectations that such sales are to be executed; |
| ● | purchases of BioManguinhos alfataliglicerase in Brazil; |
| ● | developments concerning intellectual property rights and regulatory approvals; |
| ● | the announcement of new products or product enhancements by us or our competitors; |
| ● | variations in our and our competitors’ results of operations; |
| ● | changes in earnings estimates or recommendations by securities analysts; |
| ● | developments in the biotechnology industry; and |
| ● | general market conditions and other factors, including factors unrelated to our operating performance. |
Continued market fluctuations could result in extreme volatility in the price of our common stock, which could cause a decline in the value of our common stock. Price volatility of our common stock may be worse when the trading volume of our common stock is low. We have not paid, and do not expect to pay, any cash dividends on our common stock as any earnings generated from future operations will be used to finance our operations. As a result, investors will not realize any income from an investment in our common stock until and unless their shares are sold at a profit.
Future sales of our common stock could reduce our stock price.
If our stockholders sell substantial amounts of our common stock, including shares of our common stock issuable upon conversion of our outstanding convertible notes or warrants, or if we sell a substantial amount of our common stock under our ATM program, the market price of our common stock could decrease significantly. The perception in the public market that our existing stockholders might sell shares of common stock could also depress the trading price of our common stock.
A substantial majority of our outstanding shares of our common stock are freely tradable without restriction or further registration under the federal securities laws. In addition, we may sell additional shares of our common stock in the future to raise capital. A substantial number of shares of our common stock are reserved for issuance upon the exercise of stock options, upon conversion of our outstanding convertible notes and upon the exercise of our outstanding warrants. At December 31, 2021, there were outstanding options to purchase common stock issued covering approximately 2.3 million shares of our common stock with a weighted average exercise price of approximately $4.42
56
per share. Also at December 31, 2021, there were approximately 1.8 million shares of common stock available for future for issuance in connection with future grants of incentives under our amended 2006 stock incentive plan, approximately 21.5 million shares of common stock reserved for issuance upon conversion of our outstanding 2024 Notes and approximately 14.6 million shares of common stock reserved for issuance upon the exercise of our outstanding warrants. The issuance and sale of substantial amounts of common stock, or the perception that such issuances and sales may occur, could adversely affect the market price of our common stock and impair our ability to raise capital through the sale of additional equity securities.
If securities analysts stop publishing research or reports about us or our business or if they downgrade our common stock, the market price of our common stock could decline.
The market for our common stock relies in part on the research and reports that industry or financial analysts publish about us or our business. We do not control these analysts. If any analyst who covers us downgrades our stock or lowers its future stock price targets or estimates of our operating results, the market price for our common stock could decline rapidly. Furthermore, if any analyst ceases to cover us, we could lose visibility in the market, which in turn could cause the market price of our common stock to decline.
Our common stock is listed to trade on more than one stock exchange, and this may result in price variations.
Our common stock is listed for trade on both the NYSE American and the TASE. Dual-listing may result in price variations between the exchanges due to a number of factors. First, our common stock is traded in U.S. dollars on the NYSE American and in NIS on the TASE. In addition, the exchanges are open for trade at different times of the day and on different days. For example, the TASE opens generally during Israeli business hours, Sunday through Thursday, while the NYSE American opens generally during U.S. business hours, Monday through Friday. The two exchanges also have differing vacation schedules. Differences in the trading schedules, as well as volatility in the exchange rate of the two currencies, among other factors, may result different trading prices for our common stock on the two exchanges. Other external influences may have different effects on the trading price of our common stock on the two exchanges.
Compliance with changing regulation of corporate governance and public disclosure may result in additional expenses, divert management’s attention from operating our business which could have a material adverse effect on our business.
The laws, rules, regulations and standards including the rules promulgated by the national securities exchanges, including the NYSE American, to which we are subject are changed and/or amended from time to time. New or changed laws, rules, regulations and standards are subject to varying interpretations in many cases due to their lack of specificity, and as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies, which could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. As a result, our efforts to comply with evolving laws, rules, regulations and standards are likely to continue to result in increased general and administrative expenses and a diversion of management time and attention from revenue-generating activities to compliance activities. Members of our Board of Directors and our executive officers, could face an increased risk of personal liability in connection with the performance of their duties. As a result, we may have difficulty attracting and retaining qualified directors and executive officers, which could have a material adverse effect on our business. If our efforts to comply with new or changed laws, regulations and standards differ from the activities intended by regulatory or governing bodies, we may incur additional expenses to comply with standards set by regulatory authorities or governing bodies which would have a material adverse effect on our business, results of operations and financial condition.
The issuance of preferred stock or additional shares of common stock could adversely affect the rights of our stockholders.
Our Board of Directors is authorized to issue up to 100,000,000 shares of preferred stock without any further action on the part of our stockholders. Our Board of Directors has the authority to fix and determine the voting rights, rights of redemption and other rights and preferences of preferred stock. Currently, we have no shares of preferred stock outstanding.
57
Our Board of Directors may, at any time, authorize the issuance of a series of preferred stock that would grant to holders the preferred right to our assets upon liquidation, the right to receive dividend payments before dividends are distributed to the holders of common stock and the right to the redemption of the shares, together with a premium, before the redemption of our common stock, which may have a material adverse effect on the rights of the holders of our common stock. In addition, our Board of Directors, without further stockholder approval, may, at any time, issue large blocks of preferred stock. In addition, the ability of our Board of Directors to issue shares of preferred stock without any further action on the part of our stockholders may impede a takeover of our company and may prevent a transaction that is favorable to our stockholders.
Item 1B. Unresolved Staff Comments

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following Management’s Discussion and Analysis of Financial Condition and Results of Operations (MD&A) is intended to help the reader understand our results of operations and financial condition. The MD&A is provided as a supplement to, and should be together with our consolidated financial statements and the related notes included elsewhere in this Annual Report on Form 10-K. Some of the information contained in this discussion and analysis, particularly with respect to our plans and strategy for our business and related financing, includes forward-looking statements that involve risks and uncertainties. You should read “Risk Factors” in Item 1A of this Annual Report on Form 10-K for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.
Overview
We are a biopharmaceutical company focused on the development and commercialization of recombinant therapeutic proteins primarily based on our proprietary ProCellEx® protein expression system. We developed our first commercial drug product, Elelyso®, using our ProCellEx system and we are now focused on utilizing the system to develop a pipeline of proprietary, clinically superior versions of complex recombinant therapeutic proteins that primarily target large, established pharmaceutical markets and that in most cases rely upon known biological mechanisms of action. With our experience to date, we believe ProCellEx will enable us to develop additional proprietary recombinant proteins that are therapeutically superior to existing recombinant proteins currently marketed for the same indications, including applying the unique properties of our ProCellEx system for the oral delivery of therapeutic proteins.
On August 25, 2021, we completed exchanges, or the Exchanges, of our outstanding 7.50% Senior Secured Convertible Notes due 2021, or the 2021 Notes, with institutional note holders of a substantial majority of the 2021 Notes. The Exchanges involved the exchange of an aggregate of $54.65 million principal amount of our outstanding 2021 Notes for an aggregate of $28.75 million principal amount of newly issued 7.50% Senior Secured Convertible Notes due 2024, or the 2024 Notes, $25.90 million in cash, and approximately $1.1 million in cash representing accrued and unpaid interest through the closing date. The initial conversion rate for the 2024 Notes is 563.2216 shares of Common Stock for each $1,000 principal amount of 2024 Notes (equivalent to an initial conversion price of approximately $1.7755 per share of the Common Stock), subject to adjustment in certain circumstances. This initial conversion price represents a premium of approximately 32.5% relative to the closing price of the Common Stock on the NYSE American on August 13, 2021.
Pegunigalsidase alfa (PRX-102), our proprietary plant cell culture expressed enzyme in development for the treatment of Fabry disease, is our most advanced product candidate. Our PRX-102 phase III clinical program of PRX-102 for the treatment of Fabry disease includes three separate studies: the BALANCE, BRIDGE and BRIGHT studies. The BRIDGE and BRIGHT studies have been completed, and the last patient in the BALANCE study received the final dose in the study in October 2021. The studies were designed to evaluate the potential superiority of PRX-102 over current therapies, demonstrate the potential for improved efficacy and better quality of life for patients with Fabry disease and demonstrate the safety of our drug/therapy. We are also evaluating the potential of a once-monthly treatment regimen with a higher dose of PRX-102. In addition, the phase III clinical program includes two extension studies in which subjects that participated in our phase I/II clinical trials and our phase III clinical trials may enroll and continue to be treated with PRX-102.
On February 7, 2022, an MAA for PRX-102 was submitted to, and subsequently validated by, the EMA. The submission was made after the October 8, 2021 meeting we held, together with Chiesi, with the Rapporteur and Co-Rapporteur of the EMA regarding PRX-102. At the meeting, Chiesi and the Company discussed the scope of the then anticipated MAA submission for the European Union, and the Rapporteur and Co-Rapporteur were generally supportive of the planned MAA submission for PRX-102.
On April 28, 2021, we, together with our development and commercialization partner for PRX-102, Chiesi, announced the receipt of a CRL from the FDA regarding the PRX-102 BLA. The CRL did not report any concerns relating to the potential safety or efficacy of PRX-102 in the submitted data package. In the CRL, the FDA noted that an inspection of our manufacturing facility in Carmiel, Israel, including the FDA’s subsequent assessment of any related FDA findings, is required before the FDA can approve a resubmitted BLA. Due to travel restrictions, the FDA was unable to conduct the required inspection during the review cycle. The FDA explained in the letter that it will continue to monitor the public
60
health situation as well as travel restrictions, and is actively working to define an approach for scheduling outstanding inspections. With respect to the third-party facility in Europe at which fill and finish processes are performed for PRX-102, due to COVID-19, the FDA reviewed records under Section 704(a)(4) of the FFDCA in lieu of a pre-licensing inspection. In the CRL, the FDA stated that it will communicate remaining issues to the facility in order to seek prompt resolution of any pending items. In addition to the foregoing, in the CRL, the FDA noted that Fabrazyme (agalsidase beta), a therapy used to treat Fabry patients, was recently converted to full approval and is now an “available therapy,” which must be addressed in the context of any potential resubmission of a BLA for PRX-102.
We and Chiesi participated in a Type A (End of Review) meeting with the FDA on September 9, 2021. As part of the meeting minutes provided by the FDA, which included the preliminary comments and meeting discussion, the FDA, in principle, agreed that the data package proposed to the FDA for a BLA resubmission has the potential to support a traditional approval of PRX-102 for the treatment of Fabry disease. The planned data package for the BLA resubmission, given the changed regulatory landscape in the United States, will include the final two-year analyses of the BALANCE study. We intend to continue to work collaboratively with the FDA to resolve the issues noted in the CRL and provide a new, alternative drug to Fabry patients.
Our partnership with Chiesi is based on two agreements. On October 19, 2017, Protalix Ltd. and Chiesi entered into Chiesi Ex-US Agreement and on July 23, 2018, Protalix Ltd. and Chiesi entered into the Chiesi US Agreement. Under each of the Chiesi Agreements, Chiesi made an upfront payment to Protalix Ltd. of $25.0 million in connection with the execution of each agreement. In addition, the Chiesi Ex-US Agreement provided for additional payments to Protalix Ltd. of up to $25.0 million in pegunigalsidase alfa development costs, capped at $10.0 million per year, and up to $320.0 million, in the aggregate, in regulatory and commercial milestone payments. The Chiesi US Agreement provided for additional payments to Protalix Ltd. of up to a maximum of $20.0 million to cover development costs for pegunigalsidase alfa, subject to a maximum of $7.5 million per year, and to receive additional payments of up to a maximum of $760.0 million, in the aggregate, in regulatory and commercial milestone payments. To date, Protalix Ltd. has received the complete amount of development costs to which it is entitled under the Chiesi Agreements.
Under the terms of both of the Chiesi Agreements, Protalix Ltd. is required to manufacture all of the pegunigalsidase alfa needed under the agreements, subject to certain exceptions, and Chiesi is required to purchase pegunigalsidase alfa from Protalix, subject to certain terms and conditions. Under the Chiesi Ex-US Agreement, Chiesi is required to make tiered payments of 15% to 35% of its net sales, depending on the amount of annual sales outside of the United States, as consideration for product supply. Under the Chiesi US Agreement, Chiesi is required to make tiered payments of 15% to 40% of its net sales, depending on the amount of annual sales in the United States, as consideration for product supply.
On May 13, 2021, we signed a binding term sheet with Chiesi pursuant to which we and Chiesi amended the Chiesi Agreements in order to provide the Company with near-term capital. Chiesi agreed to make a $10.0 million payment to us before the end of the second quarter of 2021 in exchange for a $25.0 million reduction in a longer term regulatory milestone payment provided in the Chiesi EX-US Agreement. All other regulatory and commercial milestone payments remain unchanged. The Company received the payment in June 2021. The Company also agreed to negotiate certain manufacturing related matters.
On May 1, 2012, the FDA approved for sale our first commercial product, taliglucerase alfa for injection, an ERT for the long-term treatment of adult patients with a confirmed diagnosis of type 1 Gaucher disease. Subsequently, taliglucerase alfa was approved for marketing by the regulatory authorities of other countries. Taliglucerase alfa is marketed under the name BioManguinhos alfataliglicerase in Brazil and certain other Latin American countries, and under the name Elelyso in other territories.
Since its approval by the FDA, taliglucerase alfa has been marketed by Pfizer, as provided in the Pfizer Agreement. In October 2015, we entered into the Amended Pfizer Agreement which amends and restates the Pfizer Agreement in its entirety. Pursuant to the Amended Pfizer Agreement, we sold to Pfizer our share in the collaboration created under the initial Pfizer Agreement for the commercialization of Elelyso in exchange for a cash payment equal to $36.0 million. Under the Amended Pfizer Agreement, Pfizer has an exclusive license to commercialize Elelyso worldwide other than Brazil; we maintain full rights to BioManguinhos alfataliglicerase in Brazil. We will continue to manufacture drug substance for Pfizer, subject to certain terms and conditions. Under the Amended Pfizer Agreement, Pfizer is responsible
61
for 100% of expenses, and entitled to all revenues globally for Elelyso, excluding Brazil, where we are responsible for all expenses and retain all revenues.
On June 18, 2013, we entered into the Brazil Agreement with Fiocruz, an arm of the Brazilian MoH, for BioManguinhos alfataliglicerase. As Fiocruz has not satisfied certain purchase commitments under the agreement, we and Fiocruz continuously discuss potential steps to maximize sales of BioManguinhos alfataliglicerase to the Brazilian MoH. We are continuing to supply BioManguinhos alfataliglicerase to Fiocruz, and patients continue to be treated with BioManguinhos alfataliglicerase in Brazil. We are discussing with Fiocruz potential actions that Fiocruz may take to comply with its purchase obligations and, based on such discussions, we will determine what we believe to be the course of action that is in our best interest.
In addition to PRX-102, our product pipeline currently includes, among other candidates:
2)PRX-115, our plant cell-expressed recombinant PEGylated uricase (urate oxidase) – a chemically modified enzyme to treat refractory gout; and
3)PRX-119, our plant cell-expressed PEGylated recombinant human DNase I product candidate being designed to elongate half-life in the circulation for NETs-related diseases.
We have licensed the rights to commercialize taliglucerase alfa worldwide (other than Brazil) to Pfizer, and the rights to commercialize pegunigalsidase alfa worldwide to Chiesi. Otherwise, we hold the worldwide commercialization rights to our other proprietary development candidates. In addition, we continuously evaluate potential strategic marketing partnerships as well as collaboration programs with biotechnology and pharmaceutical companies and academic research institutes.
Critical Accounting Policies
Our significant accounting policies are more fully described in note 1 to our consolidated financial statements appearing at the end of this Annual Report on Form 10-K. We believe that the accounting policies below are critical for one to fully understand and evaluate our financial condition and results of operations.
The discussion and analysis of our financial condition and results of operations is based on our financial statements, which we prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported revenues and expenses during the reporting periods. On an ongoing basis, we evaluate such estimates and judgments, including those described in greater detail below. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
The full extent to which the COVID-19 pandemic will directly or indirectly impact our financial condition, liquidity, or results of operations will depend on future developments that are highly uncertain, including as a result of new information that may emerge concerning COVID-19 and the actions taken to contain or treat COVID-19, as well as the economic impact on local, regional, national and international customers and markets.
Revenues
Our primary sources of revenues include our sales of BioManguinhos alfataliglicerase in Brazil, of drug substance to Pfizer under our Amended Pfizer Agreement and of drug product to Chiesi under the Chiesi Agreements. We recognize
62
revenue from the Amended Pfizer Agreement at a point in time when control over the product is transferred to customers (upon delivery).
We also generate revenues from the Chiesi agreements. According to Accounting Standards Codification 606, Revenue from Contracts with Customers, and all the related amendments, or ASC 606, a performance obligation is a promise to provide a distinct good or service or a series of distinct goods or services. Goods and services that are not distinct are bundled with other goods or services in the contract until a bundle of goods or services that is distinct is created. A good or service promised to a customer is distinct if the customer can benefit from the good or service either on its own or together with other resources that are readily available to the customer and the entity’s promise to transfer the good or service to the customer is separately identifiable from other promises in the contract.
We have identified two performance obligations in the Chiesi agreements as follows: (1) the license and research and development services and (2) contingent performance obligation regarding future manufacturing.
We determined that the license together with the research and development services should be combined into single performance obligation since Chiesi cannot benefit from the license without the research and development services. The research and development services are highly specialized and are dependent on the supply of the drug.
The future manufacturing is contingent on regulatory approvals of the drug and we deem these services to be separately identifiable from other performance obligations in the contract. Manufacturing services post-regulatory approval are not interdependent or interrelated with the license and research and development services.
The transaction price of the Chiesi Agreements was comprised of fixed consideration and variable consideration (capped research and development reimbursements). Under ASC 606, the consideration to which we would be entitled upon the achievement of contractual milestones, which are contingent upon the occurrence of future events, are a form of variable consideration. We estimate variable consideration using the most likely method. Amounts included in the transaction price are recognized only when it is probable that a significant reversal of cumulative revenues will not occur. Prior to recognizing revenue from variable consideration, we use significant judgment to determine the probability of a significant reversal of such revenue.
Since the customer benefits from the research and development services as the entity performs the service, revenue from granting the license and the research and development services is recognized over time using the cost-to-cost method. We used significant judgment when we determined the costs expected to be incurred upon satisfying the identified performance obligation.
Revenue from additional research and development services ordered by Chiesi is recognized over time using the cost-to-cost method.
Research and Development Expense
We expect our research and development expense to remain our primary expense in the near future as we continue to develop our product candidates. Research and development expense consists of:
| ● | internal costs associated with research and development activities; |
| ● | payments made to third party contract research organizations, investigative/clinical sites and consultants; |
| ● | manufacturing development costs; |
| ● | personnel-related expenses, including salaries, benefits, travel, and related costs for the personnel involved in research and development; |
| ● | activities relating to the advancement of product candidates through preclinical studies and clinical trials; and |
63
| ● | facilities and other allocated expenses, which include direct and allocated expenses for rent and maintenance of facilities, as well as laboratory and other supplies. |

We anticipate incurring increasing costs in connection with the continued development of all of the product candidates in our pipeline. Our internal resources, employees and infrastructure are not tied to any individual research project and are typically deployed across all of our projects. We currently do not record and maintain research and development costs per project.
The costs and expenses of our projects are partially funded by grants we have received from NATI. Each grant is deducted from the related research and development expenses as the costs are incurred. For additional information regarding the grant process, see “Business—Israeli Government Programs— Encouragement of Industrial Research, Development and Technology Innovation, 1984” in Item 1 of this Annual Report. There can be no assurance that we will continue to receive grants from NATI in amounts sufficient for our operations, if at all. In addition, under the two Chiesi Agreements, Protalix Ltd. was entitled to payments of up to $45.0 million in the aggregate to cover development costs for pegunigalsidase alfa, capped at $17.5 million per year. To date, Protalix Ltd. has received the complete amount of development costs to which it is entitled under the Chiesi Agreements.
At this time, due to the inherently unpredictable nature of preclinical and clinical development processes and given the early stage of our preclinical product development programs, we are unable to estimate with any certainty the costs we will incur in the continued development of the product candidates in our pipeline for potential commercialization. Clinical development timelines, the probability of success and development costs can differ materially from expectations. The current focus of our product development efforts are on pegunigalsidase alfa. Our future research and development expenses for pegunigalsidase alfa and the other product candidates will depend on the clinical success of each product candidate, as well as ongoing assessments of each product candidate’s commercial potential. In addition, we cannot forecast with any degree of certainty which product candidates may be subject to future collaborations, when such arrangements will be secured, if at all, and to what degree such arrangements would affect our development plans and capital requirements. See “Risk Factors—If we are unable to develop and commercialize our product candidates, our business will be adversely affected” and “—We may not obtain the necessary U.S., EMA or other worldwide regulatory approvals to commercialize our drug candidates in a timely manner, if at all, which would have a material adverse effect on our business, results of operations and financial condition.”
We expect our research and development expenses to continue to be our primary expense in the future as we continue the advancement of our clinical trials and preclinical product development programs for our product candidates, particularly with respect to the development of pegunigalsidase alfa. The lengthy process of completing clinical trials and seeking regulatory approvals for our product candidates requires expenditure of substantial resources. Any failure or delay in completing clinical trials, or in obtaining regulatory approvals, could cause a delay in generating product revenue and cause our research and development expense to increase and, in turn, have a material adverse effect on our operations. Due to the factors set forth above, we are not able to estimate with any certainty when we would recognize
64
any net cash inflows from our projects. See “Risk Factors—Clinical trials are very expensive, time-consuming and difficult to design and implement and may result in unforeseen costs which may have a material adverse effect on our business, results of operations and financial condition.”
Share-Based Compensation
We measure share-based compensation cost for all share-based awards at the fair value on the grant date and recognition of share-based compensation over the related service period. The fair value of stock options is determined based on the number of shares granted and the price of our ordinary shares, and calculated based on the Black-Scholes valuation model. For grants made to employees we recognize the fair value of the grant as expense over the service period using the accelerated method while for grants made to consultants and other non-employees we recognize the expenses using the straight-line accounting method.
The guidance requires companies to estimate the expected term of the option rather than simply using the contractual term of an option. Because of lack of sufficient data on past option exercises by employees, the expected term of the options could not be based on historic exercise patterns. Accordingly, we adopted the simplified method, according to which companies may calculate the expected term as the average between the vesting date and the expiration date, assuming the option was granted as a “plain vanilla” option.
In performing the valuation, we assumed an expected 0% dividend yield in the previous years and in the next years. We do not have a dividend policy and given the lack of profitability, dividends are not expected in the foreseeable future, if at all. The guidance stipulates a number of factors that should be considered when estimating the expected volatility, including the implied volatility of traded options, historical volatility and the period that the shares of the company are being publicly traded.
The risk-free interest rate used in the valuation of the options is based on the implied yield of U.S. federal reserve zero–coupon government bonds. The remaining term of the bonds used for each valuation was equal to the expected term of the grant. This methodology has been applied to all grants valued by us. The guidance requires the use of a risk–free interest rate based on the implied yield currently available on zero–coupon government issues of the country in whose currency the exercise price is expressed, with a remaining term equal to the expected life of the option being valued. This requirement has been applied for all grants valued as part of this report.
Convertible Notes
The outstanding convertible notes are accounted for using the guidance set forth in the Financial Accounting Standards Board, or the FASB, Accounting Standards Codification, or ASC, 815 requiring that we determine whether the embedded conversion option must be separated and accounted for separately. ASC 470-20 regarding debt with conversion and other options requires the issuer of a convertible debt instrument that may be settled in cash upon conversion to separately account for the liability (debt) and equity (conversion option) components of the instrument in a manner that reflects the issuer’s nonconvertible debt borrowing rate. The 2021 Notes were accounted for partially as liability and equity components of the instrument and partially as a debt host contract with an embedded derivative resulting from the conversion feature. During the year ended December 31, 2017, the embedded derivative was reclassified to additional paid in capital. The 2024 Notes were accounted for as a liability (debt) and equity component (conversion option) as the convertible notes may be settled wholly or partly in cash, at our option, when converted.
Issuance costs regarding the issuance of the 2021 Notes, as well as the debt discount and debt issuance costs from the issuance of the 2024 Notes, were deferred and amortized over the applicable convertible notes period using the effective interest rate.
On August 25, 2021, we completed the Exchanges of a substantial majority of the 2021 Notes with certain institutional note holders. The Exchanges involved the exchange of an aggregate of $54.65 million principal amount of our outstanding 2021 Notes for an aggregate of $28.75 million principal amount of newly issued 2024 Notes, $25.90 million in cash, and approximately $1.1 million in cash representing accrued and unpaid interest through the closing date. The initial conversion rate for the 2024 Notes is 563.2216 shares of Common Stock for each $1,000 principal amount of 2024 Notes (equivalent to an initial conversion price of approximately $1.7755 per share of the Common Stock), subject
65
to adjustment in certain circumstances. This initial conversion price represents a premium of approximately 32.5% relative to the closing price of the Common Stock on the NYSE American on August 13, 2021. The Exchanges are described in greater detail in Note 10 to the consolidated financial statements
For accounting purposes, as the terms of the 2021 Notes and the 2024 Notes are substantially different, the Exchanges were considered an extinguishment of debt. We allocated the fair value of the consideration transferred to the participating note holders between the 2021 Notes and their equity component based on the fair value of the liability component before the extinguishment, and the remainder was allocated to the equity component. As a result, we recognized a loss from extinguishment in the statement of operations equal to $0.8 million due to derecognition of the liability component and a reduction of stockholders’ equity of $12.2 million.
As of December 31, 2021, a total of $28.75 million aggregate principal amount of the 2024 Notes were outstanding. In addition, as of December 31, 2021, none of the 2021 Notes were outstanding.
Results of Operations
Year ended December 31, 2021 Compared to the Year Ended December 31, 2020
Revenues from Selling Goods
We recorded revenues of $16.7 million for the year ended December 31, 2021, an increase of $0.5 million, or 3%, compared to revenues of $16.2 million for the year ended December 31, 2020. An increase of $2.1 million in sales of drug substance to Pfizer was partially offset by a $1.6 million decrease in sales of drug to Brazil.
Revenues from License and R&D services
We recorded revenues from license and R&D services of $21.6 million for the year ended December 31, 2021, a decrease of $25.1 million, or 54%, compared to revenues of $46.7 million for the year ended December 31, 2020. Revenues from license and R&D services represent mainly the revenues we recognized in connection with the Chiesi Agreements. The decrease is primarily due to lower costs incurred in the year ended December 31, 2021.
Cost of Goods Sold
Cost of goods sold was $16.3 million for the year ended December 31, 2021, an increase of $5.4 million, or 50%, compared to cost of goods sold of $10.9 million for the year ended December 31, 2020. The increase in cost of goods sold was primarily the result of certain one-time manufacturing costs incurred while preparing for the then anticipated FDA approval of the PRX-102 BLA and higher manufacturing costs.
Research and Development Expenses, Net
Research and development expenses, net were $29.7 million for the year ended December 31, 2021, a decrease of $8.5 million, or 22% from $38.2 million for the year ended December 31, 2020. The decrease is primarily due to the completion of the three phase III clinical trials of PRX-102.
We expect research and development expenses to continue to be our primary expense as we enter into a more advanced stage of preclinical and clinical trials for certain of our product candidates.
Selling, General and Administrative Expenses
Selling, general and administrative expenses were $12.7 million for the year ended December 31, 2021, an increase of $1.6 million, or 14%, from $11.1 million for the year ended December 31, 2020. The increase resulted primarily from an increase in corporate costs of $1.7 million related mainly to insurance.
66
Financial Expenses and Income, Net
Financial expense, net was $7.1 million for the year ended December 31, 2021, a decrease of $2.1 million, or 23%, compared to financial expenses of $9.2 million for the year ended December 31, 2020. Financial expenses are comprised primarily of interest expense on our outstanding convertible notes equal to $3.6 million and $4.3 million for the years ended December 31, 2021 and 2020, respectively. The decrease resulted primarily from the exchange of our 2021 notes; $0.7 million decrease in interest expenses, $0.8 million decrease in amortization of debt discount, and $1.3 million decrease in related expenses offset by a $0.8 million loss on extinguishment related to the Exchanges.
Year ended December 31, 2020 Compared to the Year Ended December 31, 2019
For a discussion of the year ended December 31, 2020 compared to the year ended December 31, 2019, see Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2020.
Liquidity and Capital Resources
Our sources of liquidity include our cash balances and bank deposits. At December 31, 2021, we had $39.0 million in cash and cash equivalents. We have primarily financed our operations through equity and debt financings, business collaborations, and grants funding.
During the year ended December 31, 2021, we raised gross proceeds equal to approximately $8.8 million from sales of common stock under our ATM program through the sale of 1,867,552 shares of our common stock. In addition, we raised gross proceeds of approximately $40.2 million from a public offering of our common stock before deducting the underwriting discount and estimated expenses of the offering. In connection with the offering, we issued 8,749,999 shares of our common stock at a purchase price per share of $4.60.
On August 25, 2021, we completed Exchanges with institutional note holders of a substantial majority of the then outstanding 2021 Notes. The Exchanges involved the exchange of an aggregate of $54.65 million principal amount of 2021 Notes for an aggregate of $28.75 million principal amount of newly issued 2024 Notes, $25.90 million in cash and approximately $1.1 million in cash representing accrued and unpaid interest through the closing date. The initial conversion rate of the 2024 Notes is 563.2216 shares of our common stock per $1,000 principal amount of 2024 Notes, which is equivalent to an initial conversion price of approximately $1.7755 per share of common stock, subject to adjustment in certain circumstances. This initial conversion price represents a premium of approximately 32.5% relative to the closing price of the common stock on the NYSE American on August 13, 2021. After giving effect to the Exchanges, $3.27 million aggregate principal amount of the 2021 Notes remained outstanding. On November 15, 2021, all of the then outstanding 2021 Notes matured and were paid in full.
The 2024 Notes were issued pursuant to the 2024 Indenture which was entered into between us, the guarantors party thereto, The Bank of New York Mellon Trust Company, N.A., as trustee and Wilmington Savings Fund Society, FSB, as collateral agent. Interest on the Notes are payable semi-annually at a rate of 7.50% per annum. The 2024 Notes will mature three years after the issuance thereof, unless earlier purchased, converted, exchanged or redeemed and will be guaranteed by our subsidiaries. The 2024 Notes are secured by perfected liens on all of our assets, including those of our subsidiaries.
Cash Flows
Net cash used in operations was $10.3 million for the year ended December 31, 2021. The net loss for the year ended December 31, 2021 of $27.6 million was further increased by a $4.9 million increase in inventories and by a $1.0 million increase in accounts receivable and other assets, which was partially offset by a $13.2 million increase in contracts liability and an increase of $2.4 million in accounts payable and accruals, by $2.7 million amortization of debt issuance costs and debt discount, by a $2.4 million in share-based compensation and $1.1 million in depreciation. Net cash provided by investing activities for the year ended December 31, 2021 was $18.9 million and consisted primarily of a net decrease in bank deposits. Net cash provided by financing activities for the year ended December 31, 2021 was $12.1 million, net proceeds of $37.6 million from the issuance of common stock and of $8.6 million from the issuance of
67
common stock under the sales agreement were offset by payments of $30.0 million for convertible notes redemption and transactions costs, and $4.1 million net payment to satisfy an outstanding promissory note.
Future Funding Requirements
As a result of our significant research and development expenditures and the lack of significant revenue from sales of taliglucerase alfa, we have generated operating losses from our continuing operations since our inception. Our outstanding 2024 Notes are secured by a perfected lien on all of our assets. Under the terms of the 2024 Indenture, we are required to comply with certain covenants, including the requirement to maintain a minimum cash balance of at least $7.5 million. Failure to comply with such covenants may result in an event of default under the 2024 Indenture and, accordingly, may result in the acceleration of the payment of the notes or in additional interest payments. As of December 31, 2021, we were in compliance with all covenants.
We expect to continue to incur significant expenditures in the near future as we increase our research and developments efforts with respect to our product candidates given the receipt of the CRL from the FDA discussed above, we expect to incur additional expenses in connection with any resubmission. We cannot anticipate the costs or the timing of the occurrence of such costs. In addition, to the extent we need to obtain additional financing in connection with this process or with any additional clinical testing that may be required, it may be more difficult for us to do so given the volatility of the price of our common stock. Our material cash needs for the next 24 months will include, among other expenses, (i) costs of preclinical and clinical trials, (ii) employee salaries, (iii) payments for rent and operation of our manufacturing facilities, (iv) fees to our consultants and legal advisors, patent advisors and fees for service providers in connection with our research and development efforts and (v) payment of interest on our outstanding 2024 Notes. We believe that the funds currently available to us are sufficient to satisfy our capital needs for at least 12 months.
As discussed above, we may be required to raise additional capital to develop our product candidates and continue research and development activities. Our ability to raise capital, and the amounts of necessary capital, will depend on many other factors, including:
| ● | our efforts, combined with those of Chiesi, to file for resubmission with the FDA and to commercialize PRX-102; |
| ● | our progress in commercializing BioManguinhos alfataliglicerase in Brazil; |
| ● | the duration and cost of discovery and preclinical development and laboratory testing and clinical trials for our product candidates; |
| ● | the timing and outcome of regulatory review of our product candidates; |
| ● | the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patent claims and other intellectual property rights; and |
| ● | the costs associated with any litigation claims. |
We expect to finance our future cash needs through corporate collaborations, licensing or similar arrangements, public or private equity offerings and/or debt financings. We currently do not have any commitments for future external funding, except with respect to the development-related payments and milestone payments that may become payable under the Chiesi Agreements. On July 2, 2021, we entered into the Sales Agreement in connection with a new ATM program pursuant to which we may sell from time to time through the Agent ATM Shares having an aggregate offering price of up to $20.0 million. On the same date, we terminated our former ATM program.
68
Contractual obligations
Our contractual obligations include obligations under our convertible notes, operating lease obligations, purchase obligations, a certain clinical contract and the liability for employee rights upon retirement.
Our convertible senior notes had an aggregate outstanding principal balance of $28.75 million at December 31, 2021. The notes will mature on September 1, 2024 unless earlier purchased, converted, exchanged or redeemed, and interest is payable on the note semi-annually at a rate of 7.50% per annum.
We lease certain assets under operating leases, which expire through 2026, with an option to extend the lease on our main facility to 2031. The leases relate primarily to office, laboratory and manufacturing space and vehicles used by our employees. Our aggregate future minimum commitments under these facility and vehicles leases over the next five fiscal years is approximately $5.1 million as of December 31, 2021.
As of December 31, 2021, we are subject to open purchase orders issued to certain suppliers and other vendors mainly in connection with our research and development and manufacturing activities that were outstanding as of December 31, 2021 for approximately $5.1 million over the next five fiscal years.
We have a contractual obligation of approximately $853,000 as of December 31, 2021 payable over the fiscal year ended December 31, 2022. In addition, we enter into contracts in the normal course of business with CROs, CMOs and other third parties for clinical trials, preclinical and other research studies and manufacturing services. These contracts do not contain minimum purchase commitments and are cancelable by us upon prior written notice. Payments due upon cancellation consist only of payments for services provided or expenses incurred, including non-cancelable obligations of our service providers, up to the date of cancellation.
As of December 31, 2021, we have a contractual obligation of approximately $2.5 million for employee rights upon retirement.
We are also party to certain research and license agreements. If all of the contingencies with respect to milestone payments under our research and license agreements are met, as of December 31, 2021, the aggregate milestone payments payable would be approximately $8.4 million, and would be payable, if at all, as our projects progress over the course of a number of years. The royalty payments payable by our company in connection with sales of each of our product candidates, if any, shall not exceed low, single-digit percentages of net sales of the relevant product.
Effects of Currency Fluctuations
Currency fluctuations could affect us through increased or decreased acquisition costs for certain goods and services. We do not believe currency fluctuations have had a material effect on our results of operations during the years ended December 31, 2020 or 2021.
Recently Issued Accounting Pronouncements
Certain recently issued accounting pronouncements are discussed in note 1r of the financial statements included in Item 8 of this Annual Report on Form 10-K.
Item 7A. Quantitative and Qualitative Disclosures about Market Risk
Currency Exchange Risk
The currency of the primary economic environment in which our operations are conducted is the U.S. dollar. Most of our revenues and approximately 65% of our expenses and capital expenditures, including the repayment of our 2021 Notes, are incurred in dollars, and a significant source of our financing has been provided in U.S. dollars. Since the dollar is the functional currency, monetary items maintained in currencies other than the dollar are remeasured using the rate of exchange in effect at the balance sheet dates and non-monetary items are remeasured at historical exchange rates. Revenue and expense items are remeasured at the average rate of exchange in effect during the period in which they occur. Foreign currency translation gains or losses are recognized in the statement of operations.
69
Approximately 31% of our costs, including salaries, expenses and office expenses, are incurred in NIS. Inflation in Israel may have the effect of increasing the U.S. dollar cost of our operations in Israel. If the U.S. dollar declines in value in relation to the NIS, it will become more expensive for us to fund our operations in Israel. A revaluation of 1% of the NIS will affect our loss before tax by less than 1%. The exchange rate of the U.S. dollar to the NIS, based on exchange rates published by the Bank of Israel, was as follows:
Year Ended December 31, | ||||||
| 2019 | 2020 | 2021 | |||
Average rate for period |
| 3.565 | 3.442 | 3.230 | ||
Rate at period-end |
| 3.456 | 3.215 | 3.110 | ||
To date, we have not engaged in hedging transactions. In the future, we may enter into currency hedging transactions to decrease the risk of financial exposure from fluctuations in the exchange rate of the U.S. dollar against the NIS. These measures, however, may not adequately protect us from material adverse effects due to the impact of inflation in Israel.
Interest Rate Risk
Our exposure to market risk is confined to our cash and cash equivalents. We consider all short term, highly liquid investments, which include short-term deposits with original maturities of three months or less from the date of purchase, that are not restricted as to withdrawal or use and are readily convertible to known amounts of cash, to be cash equivalents. The primary objective of our investment activities is to preserve principal while maximizing the interest income we receive from our investments, without increasing risk. We invest any cash balances primarily in bank deposits and investment grade interest-bearing instruments. We are exposed to market risks resulting from changes in interest rates. We do not use derivative financial instruments to limit exposure to interest rate risk. Our interest gains may decline in the future as a result of changes in the financial markets.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure
None.
Item 9A. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
We conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Form 10-K. The controls evaluation was conducted under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer. Disclosure controls and procedures are controls and procedures designed to reasonably assure that information required to be disclosed in our reports filed under the Exchange Act, such as this Form 10-K, is recorded, processed, summarized and reported within the time periods specified in the Commission’s rules and forms. Disclosure controls and procedures are also designed to reasonably assure that such information is accumulated and communicated to our management, including the Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.
The evaluation of our disclosure controls and procedures included a review of the controls’ objectives and design, our implementation of the controls and their effect on the information generated for use in this Annual Report on Form 10-K. This type of evaluation will be performed on a quarterly basis so that the conclusions of management, including the Chief Executive Officer and Chief Financial Officer, concerning the effectiveness of the disclosure controls and procedures can be reported in our periodic reports on Form 10-Q and Form 10-K. The overall goals of these various evaluation activities are to monitor our disclosure controls and procedures, and to modify them as necessary. Our intent is to maintain the disclosure controls and procedures as dynamic systems that change as conditions warrant.
70
Based on the controls evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this Form 10-K, our disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified by the Commission, and that material information related to our company and our consolidated subsidiaries are made known to management, including the Chief Executive Officer and Chief Financial Officer, particularly during the period when our periodic reports are being prepared.
Management’s Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures that: (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that receipts and expenditures of our company are being made only in accordance with authorizations of management and our directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.
Management assessed our internal control over financial reporting as of December 31, 2021, the end of our fiscal year. Management based its assessment on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Management’s assessment included evaluation of elements such as the design and operating effectiveness of key financial reporting controls, process documentation, accounting policies and our overall control environment.
Based on our assessment, management has concluded that our internal control over financial reporting was effective as of the end of the fiscal year to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with U.S. generally accepted accounting principles. We reviewed the results of management’s assessment with the Audit Committee of our Board of Directors.
Inherent Limitations on Effectiveness of Controls
Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all error and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Further, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within a company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of controls effectiveness to future periods are subject to risks. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures.

Changes in internal controls
There were no changes in our internal control over financial reporting (as defined in Rules 13a-15f and 15d-15f under the Exchange Act) that occurred during the quarter ended December 31, 2021 that have materially affected, or that are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm
To the Board of Directors and Stockholders of Protalix Biotherapeutics, Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Protalix BioTherapeutics, Inc. and its subsidiaries (the “Company”) as of December 31, 2021 and 2020, and the related consolidated statements of operations, changes in capital deficiency and cash flows for each of the three years in the period ended December 31, 2021, including the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021 in conformity with accounting principles generally accepted in the United States of America.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matters
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not
F-2
alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.
Revenue Recognition - Estimated Costs to Complete License and Research and Development ("R&D") Services Performance Obligation
As discussed in Notes 2(b) and 8 to the consolidated financial statements, $21.6 million of the Company’s total revenues for the year ended December 31, 2021 was generated from license and R&D services. For the Company’s license and R&D services, control transfers over time; accordingly, management recognizes revenue based on the extent of progress in each period towards completion of the performance obligation. The selection of the measure of progress towards completion requires management judgment and is based on the nature of the products or services to be provided. As disclosed by management, the Company uses the cost-to-cost method to measure progress for its contracts because management believes that measure best depicts the transfer of control to the customer, which occurs as the Company incurs costs on the contracts.
Under the cost-to-cost method, the extent of progress towards completion is based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation, which includes both the actual costs already incurred and the estimated costs to complete. Revenues are recognized proportionately as costs are incurred. Due to the nature of the work required to be performed on the performance obligation, management’s estimation of costs at completion is complex and requires significant judgment. Management has disclosed that there are many factors that can affect the accuracy of cost estimates, including, but not limited to, the availability and costs of labor and materials resources, and productivity.
The principal considerations for our determination that performing procedures relating to revenue recognition – estimated costs to complete license and R&D services performance obligation is a critical audit matter are the significant judgment by management when developing the estimated costs to complete the performance obligation. This in turn led to significant auditor judgment, subjectivity and effort in performing procedures to evaluate management's estimate of the costs to complete the performance obligation.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included, among others, evaluating and testing management’s process for determining the estimate of costs at completion, which included evaluating the reasonableness of significant assumptions, including the estimated expected labor costs used by management and considering the factors that can affect the accuracy of those estimates. Evaluating the reasonableness of significant assumptions used involved assessing management’s ability to reasonably estimate costs to complete the performance obligation by (i) performing a comparison of the originally estimated costs and actual costs incurred; (ii) evaluating the timely identification of circumstances that may warrant a modification to the estimated costs to complete, including actual costs in excess of estimates; and (iii) testing management’s process for evaluating the Company’s ability to properly execute the work plan and design phases consistent with customer expectations for completing the performance obligation.

NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES
a. General
Protalix BioTherapeutics, Inc. (collectively with its subsidiaries, the “Company”) and its wholly-owned subsidiaries, Protalix Ltd. and Protalix B.V. (collectively, the “Subsidiaries”), are biopharmaceutical companies focused on the development and commercialization of recombinant therapeutic proteins based on the Company’s proprietary ProCellEx® protein expression system (“ProCellEx”). To date, the Company has successfully developed taliglucerase alfa (marketed under the name BioManguinhos alfataliglicerase in Brazil and certain other Latin American countries and Elelyso® in the rest of the territories) for the treatment of Gaucher disease that has been approved for marketing in the United States, Brazil, Israel and other markets. The Company has a number of product candidates in varying stages of the clinical development process. The Company’s strategy is to develop proprietary recombinant proteins that are therapeutically superior to existing recombinant proteins currently marketed for the same indications.
On August 25, 2021, the Company completed exchanges (the “Exchanges”) of the Company’s outstanding
The most advanced investigational drug in the Company’s product pipeline is pegunigalsidase alfa, or PRX-102, a therapeutic protein candidate for the treatment of Fabry disease, a rare, genetic lysosomal disorder, which is the subject of a phase III clinical program. The PRX-102 phase III clinical program includes three separate studies which are referred to as the BALANCE study, the BRIDGE study and the BRIGHT study. The BRIDGE and BRIGHT studies have been completed, and the last patient from the BALANCE study received the final dose of the study in October 2021. In addition, the phase III clinical program includes two extension studies in which subjects that participated in our phase I/II clinical trials and our phase III clinical trials may enroll and continue to be treated with PRX-102. The studies are designed to evaluate the potential superiority of PRX-102 over current therapies in a head-to-head study and a switch-over study, evaluate the potential for improved efficacy and better quality of life for patients with Fabry disease and evaluate the safety of our drug/therapy.
On February 7, 2022, a Marketing Authorization Application (“MAA”) for PRX-102 was submitted to, and subsequently validated by, the European Medicines Agency (“EMA”). The submission was made after the October 8, 2021 meeting the Company held, together with Chiesi, with the Rapporteur and Co-Rapporteur of the EMA regarding PRX-102. At the meeting, Chiesi and the Company discussed the scope of the then anticipated MAA submission for the European Union, and the Rapporteur and Co-Rapporteur were generally supportive of the planned MAA submission for PRX-102.
On April 28, 2021, the Company, together with its development and commercialization partner for PRX-102, Chiesi Farmaceutici S.p.A. (“Chiesi”), announced that the receipt of a Complete Response Letter (CRL) from the U.S. Food and Drug Administration (the “FDA”) regarding the biologics license application (“BLA”) for PRX-102 for the treatment of adult patients with Fabry disease. The PRX-102 BLA was submitted to the FDA on May 27, 2020 under the FDA’s Accelerated Approval pathway, and
F-9
was subsequently accepted by the FDA and granted Priority Review designation. The CRL did not report any concerns relating to the potential safety or efficacy of PRX-102 in the submitted data package. In the CRL, the FDA noted that an inspection of the Company’s manufacturing facility in Carmiel, Israel, including the FDA’s subsequent assessment of any related FDA findings, is required before the FDA can approve a resubmitted BLA. Due to travel restrictions, the FDA was unable to conduct the required inspection during the review cycle. The FDA explained in the letter that it will continue to monitor the public health situation as well as travel restrictions, and is actively working to define an approach for scheduling outstanding inspections. With respect to the third-party facility in Europe at which fill and finish processes are performed for PRX-102, due to the novel coronavirus disease (“COVID-19”), the FDA reviewed records under Section 704(a)(4) of the Federal Food, Drug, and Cosmetic Act in lieu of a pre-licensing inspection. In the CRL, the FDA stated that it will communicate remaining issues to the facility in order to seek prompt resolution of any pending items. In addition to the foregoing, in the CRL, the FDA noted that Fabrazyme (agalsidase beta), a therapy used to treat Fabry patients, was recently converted to full approval and is now an “available therapy,” which must be addressed in the context of any potential resubmission of a BLA for PRX-102.
The Company and Chiesi participated in a Type A (End of Review) meeting with the FDA on September 9, 2021. As part of the meeting minutes provided by the FDA, which included the preliminary comments and meeting discussion, the FDA, in principle, agreed that the data package proposed to the FDA for a BLA resubmission has the potential to support a traditional approval of PRX-102 for the treatment of Fabry disease. The planned data package for the BLA resubmission, given the changed regulatory landscape in the United States, will include the final two-year analyses of the BALANCE study. The Company intends to continue to work collaboratively with the FDA to resolve the issues noted in the CRL and provide a new, alternative drug to Fabry patients.
In addition to PRX-102, the Company’s product pipeline currently includes, among other candidates:
| (1) | alidornase alfa, or PRX-110, a proprietary plant cell recombinant human Deoxyribonuclease 1, or DNase, which has successfully completed a phase II efficacy and safety study; the Company’s exclusive worldwide license agreement with SarcoMed USA Inc. with respect to PRX-110 for use in the treatment of any human respiratory disease or condition including, but not limited to, sarcoidosis, pulmonary fibrosis, and other related diseases via inhaled delivery expired during 2021; we are continuing to evaluate potential strategic marketing partnerships and collaboration programs with biotechnology and pharmaceutical companies for this product candidate for various respiratory indications; |
| (2) | PRX-115, the Company’s plant cell-expressed recombinant PEGylated uricase (urate oxidase) – a chemically modified enzyme to treat refractory gout; and |
| (3) | PRX-119, the Company’s plant cell-expressed PEGylated recombinant human DNase I product candidate being designed to elongate half-life in the circulation for NETs-related diseases. |
Obtaining marketing approval with respect to any product candidate in any country is dependent on the Company’s ability to implement the necessary regulatory steps required to obtain such approvals. The Company cannot reasonably predict the outcome of these activities.
On July 2, 2021, the Company entered into an At The Market Offering Agreement (the “Sales Agreement”) with H.C. Wainwright & Co., LLC, as the Company’s sales agent (the “Agent”).

On June 18, 2013, the Company entered into a Supply and Technology Transfer Agreement (the “Brazil Agreement”) with Fundação Oswaldo Cruz (“Fiocruz”), an arm of the Brazilian Ministry of Health (the “Brazilian MoH”), for taliglucerase alfa. Fiocruz’s purchases of BioManguinhos alfataliglicerase to date have been significantly below certain agreed upon purchase milestones and, accordingly, the Company has the right to terminate the Brazil Agreement. Notwithstanding the termination right, the Company is, at this time, continuing to supply BioManguinhos alfataliglicerase to Fiocruz under the Brazil Agreement, and patients continue to be treated with BioManguinhos alfataliglicerase in Brazil.
COVID-19, which was declared by the World Health Organization to be a global pandemic on March 11, 2020, has had numerous adverse effects on the global economy. To date, the Company's clinical trials have not been adversely affected by COVID-19, although certain practices the Company has adopted in its offices and facilities in an effort to promote social distancing have resulted in minor delays in the performance of administrative activities outside of the clinical programs. The Company continues to face uncertainty as to the degree and duration of that impact going forward. The Company does not know the length of time that the pandemic and related disruptions will continue, the impact of governmental regulations or easement of regulations in response to the strengthening or weakening of the pandemic, or the degree of overall potentially permanent changes in consumer behavior that may be caused by the pandemic.
The Company believes that its cash and cash equivalents as of December 31, 2021 are sufficient to satisfy the Company’s capital needs for at least 12 months from the date that these financial statements are issued.
b. Basis of presentation
The Company’s financial statements have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”).
c. Use of estimates in the preparation of financial statements
The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates. As applicable to these consolidated financial statements, the most significant estimates relate to revenue recognition.
The severity, magnitude and duration, as well as the economic consequences, of the COVID-19 pandemic, are uncertain, rapidly changing and difficult to predict. As a result, the accounting estimates and assumptions may change over time in response to COVID-19.
d. Functional currency
The dollar is the currency of the primary economic environment in which the operations of the Company and its Subsidiaries are conducted. The Company’s revenues are derived in dollars. Most of the Company’s expenses and capital expenditures are incurred in dollars, and the major source of the Company’s financing has been provided in dollars.
F-12
Transactions and balances originally denominated in dollars are presented at their original amounts. Balances in non-dollar currencies are translated into dollars using historical and current exchange rates for non-monetary and monetary balances, respectively. For non-dollar transactions and other items (stated below) reflected in the statements of operations, the following exchange rates are used: (i) for transactions – exchange rates at the transaction dates or average rates; and (ii) for other items (derived from non-monetary balance sheet items such as depreciation and amortization, etc.) – historical exchange rates. Currency translation gains and losses are recorded as financial income or expenses, as appropriate.
e. Cash equivalents
The Company considers all short-term, highly liquid investments, which include short-term bank deposits with original maturities of three months or less from the date of purchase, that are not restricted as to withdrawal or use and are readily convertible to known amounts of cash, to be cash equivalents.
f. Accounts Receivables
Accounts receivable have been reduced by an allowance for doubtful accounts. The Company maintains the allowance for estimated losses resulting from the inability of the Company’s customers to make required payments. The allowance represents the current estimate of lifetime expected credit losses over the remaining duration of existing accounts receivable considering current market conditions and supportable forecasts when appropriate. The estimate is a result of the Company’s ongoing evaluation of collectability, customer creditworthiness, historical levels of credit losses, and future expectations.
No write-off activity and recoveries for the periods presented were recognized.
g. Inventories
Inventories are valued at the lower of cost or net realizable value. Cost of raw and packaging materials and purchased products is determined using the “moving average” basis.
Cost of finished products is determined as follows: the value of the raw and packaging materials component is determined primarily using the “moving average” basis; the value of the labor and overhead component is determined on an average basis over the production period.
Inventory is written down for estimated obsolescence based upon management assumptions about future demand and market conditions.
h. Property and equipment
1. Property and equipment are stated at cost, net of accumulated depreciation and amortization.
2. The Company’s assets are depreciated by the straight-line method on the basis of their estimated useful lives as follows:
| Years | |
Laboratory equipment |
| |
Furniture |
| |
Computer equipment |
|
Leasehold improvements are amortized by the straight-line method over the shorter of (i) the expected lease term and (ii) the estimated useful life of the improvements.
F-13
i. Impairment in value of long-lived assets
The Company tests long-lived assets for impairment if an indication of impairment exists. If the sum of expected future cash flows of definite life assets (undiscounted and without interest charges) is less than the carrying amount of such assets, the Company recognizes an impairment loss, and writes down the assets to their estimated fair values.
j. Income taxes
1. Deferred income taxes
Deferred taxes are determined utilizing the assets and liabilities method based on the estimated future tax effects of the differences between the financial accounting and tax bases of assets and liabilities under the applicable tax laws. Deferred tax balances are computed using the tax rates expected to be in effect when those differences reverse. A valuation allowance in respect of deferred tax assets is provided if, based upon the weight of available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized. The Company has provided a full valuation allowance with respect to its deferred tax assets. The Company used statutory tax rates of
2. Uncertainty in income taxes
Tax benefits recognized in the financial statements are those that the Company’s management deems at least more likely than not to be sustained, based on technical merits. The amount of benefits recorded for these tax benefits is measured as the largest benefit the Company’s management deems more likely than not to be sustained.
k. Revenue Recognition
The Company accounts for revenue pursuant to Accounting Standards Codification, Topic 606, Revenue from Contracts with Customers (“ASC 606”). Under ASC 606, a contract with a customer exists only when: the parties to the contract have approved it and are committed to perform their respective obligations, the Company can identify each party’s rights regarding the distinct goods or services to be transferred (“performance obligations”), the Company can determine the transaction price for the goods or services to be transferred, the contract has commercial substance and it is probable that the Company will collect the consideration to which it will be entitled in exchange for the goods or services that will be transferred to the customer.
Revenues are recorded in the amount of consideration to which the Company expects to be entitled in exchange for performance obligations upon transfer of control to the customer.
1. Revenues from selling products
The Company recognizes revenues from selling goods at a point in time when control over the product is transferred to customers (upon delivery).
2. Revenues from Chiesi Agreements
The Company has identified
F-14
The Company determined that the license together with the research and development services should be combined into single performance obligation since Chiesi cannot benefit from the license without the research and development services. The research and development services are highly specialized and are dependent on the supply of the drug.
The future manufacturing is contingent on regulatory approvals of the drug and the Company deems these services to be separately identifiable from other performance obligations in the contract. Manufacturing services post-regulatory approval are not interdependent or interrelated with the license and research and development services.
The transaction price was comprised of fixed consideration and variable consideration (capped research and development reimbursements). Under ASC 606, the consideration to which the Company would be entitled upon the achievement of contractual milestones, which are contingent upon the occurrence of future events, are a form of variable consideration. The Company estimates variable consideration using the most likely method. Amounts included in the transaction price are recognized only when it is probable that a significant reversal of cumulative revenues will not occur. Prior to recognizing revenue from variable consideration, the Company uses significant judgment to determine the probability of significant reversal of such revenue.
Since the customer benefits from the research and development services as the entity performs the service, revenue from granting the license and the research and development services is recognized over time using the cost-to-cost method. The Company used significant judgment when it determined the costs expected to be incurred upon satisfying the identified performance obligation.
Revenue from additional research and development services ordered by Chiesi, is recognized over time using the cost-to-cost method.
3. Revenue from R&D services
Revenue from the research and development services is recognized over time using the cost-to-cost method since the customer benefits from the research and development services as the entity performs the service.
l. Research and development costs
Research and development costs are expensed as incurred and consist primarily of personnel, subcontractors and consultants (mainly in connection with clinical trials), facilities, equipment and supplies for research and development activities. Grants received by the Israeli Subsidiary from the National Authority for Technological Innovation (“NATI”) are recognized when the grant becomes receivable, provided there is reasonable assurance that the Company or the Subsidiaries will comply with the conditions attached to the grant and there is reasonable assurance the grant will be received. The grant is deducted from the research and development expenses as the applicable costs are incurred. In connection with purchases of assets, amounts assigned to intangible assets to be used in a particular research and development project that have no alternative future use are charged to research and development costs at the purchase date. Costs incurred for performing research and development services are included in research and development expenses.
m. Concentration of credit risks and trade receivable
Financial instruments that potentially subject the Company to concentration of credit risk consist principally of bank deposits. The Company’s deposits are instruments with highly rated financial institutions, mainly in Israeli banks, and, as a matter of policy, limits the amounts of credit exposure to any one financial institution. The Company has not experienced any credit losses in these accounts and does not
F-15
believe it is exposed to any significant credit risk on these instruments. The Company’s trade receivables represent amounts to be received from its customers. The Company does not require its customers to post collateral with respect to receivables.
As of December 31, 2021, the accounts receivables balance was composed of $
n. Share-based compensation
The Company accounts for share-based payment awards classified as equity awards, including stock-based option awards and restricted stock units, using the grant-date fair value method. The fair value of share-based payment transactions is recognized as an expense over the requisite service period.
The Company calculates the fair value of stock-based option awards on the date of grant using the Black-Scholes option pricing model. This option pricing model requires estimates as to the option’s expected term and the price volatility of the underlying stock.
The Company measures compensation expense for the restricted stock units based on the market value of the underlying stock at the date of grant.
The Company elected to recognize compensation cost for awards to employees with only service conditions that has a graded vesting schedule using the accelerated method based on the multiple-option award approach. Options granted to consultants and other service providers are recognized over the related service period using the straight-line method.
The Company elects to account for forfeitures as they occur.
o. Net loss per share
Basic and diluted loss per share (“LPS”) are computed by dividing net loss by the weighted average number of shares of the Company’s Common Stock outstanding for each period. The calculation of diluted LPS does not include approximately
p. Convertible notes
The outstanding convertible notes are accounted for using the guidance set forth in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 815 requiring that the Company determine whether the embedded conversion option must be separated and accounted for separately. ASC 470-20 regarding debt with conversion and other options requires the issuer of a convertible debt instrument that may be settled in cash upon conversion to separately account for the liability (debt) and equity (conversion option) components of the instrument in a manner that reflects the issuer’s nonconvertible debt borrowing rate. The 2021 Notes were accounted for partially as liability and equity components of the instrument and partially as a debt host contract with an embedded derivative resulting from the conversion feature. During the year ended December 31, 2017, the embedded derivative was reclassified to additional paid in capital. The 2024 Notes were accounted for as a liability (debt) and equity component (conversion option) as the convertible notes may be settled wholly or partly in cash, at the option of the Company, when converted.
Issuance costs regarding the issuance of the 2021 Notes, as well as the debt discount and debt issuance costs from the issuance of the 2024 Notes, were deferred and amortized over the applicable convertible notes period using the effective interest rate.
F-16
As of December 31, 2021, a total of $
q. Leases
The Company adopted ASC 842 on January 1, 2019, using a modified retrospective transition approach, with certain practical expedients, and as a result did not adjust prior periods.
Leases are classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the statement of operations. The Company determines if an arrangement is a lease at inception. Lease classification is governed by five criteria in ASC 842-10-25-2. If any of these five criteria is met, the Company classifies the lease as a finance lease. Otherwise, the Company classifies the lease as an operating lease. The Company does not have any finance leases.
Operating leases are included in operating lease right-of-use (“ROU”) assets and operating lease liabilities in the consolidated balance sheets.
ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating and finance lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. The Company uses its incremental borrowing rate based on the information available at the commencement date to determine the present value of the lease payments.
The Company elected the package of transition practical expedients permitted under the transition guidance within the new standard which, among other things, allows the Company to carryforward the historical lease classification.
The lease standard also provides practical expedients for an entity’s ongoing accounting. The Company elected the short-term lease recognition exemption for all leases with a term shorter than 12 months. This means, for those leases, the Company does not recognize ROU assets or lease liabilities, including not recognizing ROU assets or lease liabilities for existing short-term leases of those assets in transition.
Lease terms include options to extend or terminate the lease when it is reasonably certain that the Company will either exercise or not exercise the option to renew or terminate the lease. The Company recognizes lease expenses over the lease term on a straight-line basis.
The depreciable life of leasehold improvements is limited by the expected lease term, unless there is a transfer of title or a purchase option for the leased asset reasonably certain of exercise.
Additionally, following the adoption of ASC 842 and in subsequent measurements, the Company applies the portfolio approach to account for the operating lease ROU assets and liabilities for certain car leases and incremental borrowing rates.
r. Recently issued accounting pronouncements, not yet adopted
In August 2020, the FASB issued ASU 2020-06 “Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815 – 40).” This guidance simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. The amendments to this guidance are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently evaluating the impact of the adoption of this standard on its consolidated financial statements.
F-17
In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” In addition, in January 2021, the FASB issued ASU 2021-01, “Reference Rate Reform (Topic 848) - Scope.” The amendments in these ASUs apply to all entities that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. Together, these ASUs provide optional expedients and exceptions for applying generally accepted accounting principles (GAAP) to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. These ASUs were effective upon issuance and may be applied prospectively to contract modifications and hedging relationships entered into or evaluated through December 31, 2022. The adoption of this standard is not expected to have material impact on the Company's consolidated financial statements.

NOTE 5 - LIABILITY FOR EMPLOYEE RIGHTS UPON RETIREMENT
The Israeli Subsidiary is required to make a severance payment upon dismissal of an employee or upon termination of employment in certain circumstances. The severance pay liability to the employees (based upon length of service and the latest monthly salary - one month’s salary for each year employed) is recorded on the Company’s balance sheets under “Liability for employee rights upon retirement.” The liability is recorded as if it were payable at each balance sheet date on an undiscounted basis.
The liability is funded in part from the purchase of insurance policies or by the establishment of pension funds with dedicated deposits in the funds. The amounts used to fund these liabilities are included in the Company’s balance sheets under “Funds in respect of employee rights upon retirement.” These policies are the Company’s assets. However, under labor agreements and subject to certain limitations, any policy may be transferred to the ownership of the individual employee for whose benefit the funds were deposited. In the years ended December 31, 2019, 2020 and 2021, the Company deposited approximately $
In accordance with the current employment agreements with certain employees, the Company makes regular deposits with certain insurance companies for accounts controlled by each applicable employee in order to secure the employee’s rights upon retirement. The Company is fully relieved from any severance pay liability with respect to each such employee after it makes the payments on behalf of the employee. The liability accrued in respect of these employees and the amounts funded, as of the respective agreement dates, are not reflected in the Company’s balance sheets, as the amounts funded are not under the control and management of the Company and the pension or severance pay risks have been irrevocably transferred to the applicable insurance companies (the “Contribution Plans”).

Interest on the Notes will be paid semi-annually at a rate of
For accounting purposes, as the terms of the 2021 Notes and the 2024 Notes are substantially different, the Exchanges were considered an extinguishment of debt. The Company allocated the fair value of the consideration transferred to the participating note holders between the 2021 Notes and their equity component based on the fair value of the liability component before the extinguishment, and the remainder was allocated to the equity component. As a result, the Company recognized a loss from extinguishment in the statement of operations equal to $
The Company accounted for the 2024 Notes as a liability (debt) and equity component (conversion option) as the convertible notes may be settled wholly or partly in cash, at the option of the Company, when converted.

NOTE 11 - FAIR VALUE MEASUREMENT
The Company discloses fair value measurements for financial assets and liabilities. Fair value is based on the price that would be received from the sale of an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date.
The accounting standard establishes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described below:
Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.
Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.
Level 3: Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.
In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible and considers counterparty credit risk in its assessment of fair value.
The fair value of the financial instruments included in the working capital of the Company is usually identical or close to their carrying value.

NOTE 12 - TAXES ON INCOME
| a. | The Company |
Protalix BioTherapeutics, Inc. is taxed according to U.S. tax laws. The Company’s income is taxed in the United States at the rate of up to
On December 22, 2017, the Tax Cuts and Jobs Act (the “Act”) was enacted into law. The new legislation represents fundamental and dramatic modifications to the U.S. tax system. The Act contained several key tax provisions that impacted the Company including the reduction of the maximum U.S. federal corporate income tax rate from 35% to 21%, effective January 1, 2018. Other significant changes under the Act included, among others, a one-time repatriation tax on accumulated foreign earnings, a limitation of net operating loss (“NOL”) deduction to 80% of taxable income, and indefinite carryover of post-2017 NOLs. The Act also repealed the corporate alternative minimum tax for tax years beginning after December 31, 2017. Losses generated prior to January 1, 2018 will still be subject to the 20-year carryforward limitation and the alternative minimum tax. Other impacts due to the Act included the repeal of the domestic manufacturing deduction, modification of taxation of controlled foreign corporations, a base erosion anti-abuse tax, modification of interest expense limitation rules, modification of limitation on deductibility of excessive executive compensation, and taxation of global intangible low-taxed income.
Modification of interest expense limitation rules under the Act provides generally that for taxable years 2019-2022 interest expense deduction shall be limited to 30% of the EBITDA and for taxable years 2022 onwards to 30% of EBIT. Disallowed interest deduction may be carried forward indefinitely. The Company believes that any potential impact (if applicable) of this limitation will be offset by utilization of available NOLs.
U.S. GAAP requires that the impact of tax legislation be recognized in the period in which the law was enacted.
The Company believes that all future profits of its subsidiaries will be indefinitely reinvested or that there is no expectation to distribute any taxable dividends from these subsidiaries. The determination of the amount of the unrecognized deferred tax liability related to the undistributed earnings is estimated as an immaterial amount.
b. Protalix Ltd.
The Company as a “foreign-investment company” measures its results for tax purposes in dollar based on Income Tax Regulations (Bookkeeping Principles of Foreign Invested Companies and of Certain Partnerships and the Determination of Their Taxable Income), 1986. The Israeli Subsidiary is taxed according to Israeli tax laws:

| 1. | Tax rates |
The income of the Israeli Subsidiary, other than income from “Approved Enterprises,” is taxed in Israel at the regular corporate tax rates.
The corporate tax rate was
Capital gain on a sale of assets is subject to capital gain tax according to the corporate tax rate in effect in the year during which the assets are sold.
| 2. | The Law for the Encouragement of Capital Investments, 1959 (the “Encouragement of Capital Investments Law”) |
Under the Encouragement of Capital Investments Law, including Amendment No. 60 to the Encouragement of Capital Investments Law as published in April 2005, by virtue of the “Approved Enterprise” or “Benefited Enterprise” status the Israeli Subsidiary is entitled to various tax benefits as follows:
a. Reduced tax rates
Income derived from the Approved Enterprise during a 10-year period commencing upon the year in which the enterprise first realizes taxable income is tax exempt, provided that the maximum period to which it is restricted by the Encouragement of Capital Investments Law has not elapsed.
The Israeli Subsidiary has an “Approved Enterprise” plan since 2004 and “Benefited Enterprise” plan since 2009. The period of benefits in respect of the main enterprise of the Company has not yet commenced. The period during which the Company is entitled to benefits in connection with the Benefited Enterprise expires in 2022.
If the Israeli Subsidiary subsequently pays a dividend out of income derived from the “Approved Enterprise” or “Benefited Enterprise” during the tax exemption period, it will be subject to tax on the gross amount distributed (including the company tax on these amounts), at the rate which would have been applicable if such income not been exempted.
b. Accelerated depreciation
The Israeli Subsidiary is entitled to claim accelerated depreciation, as provided by Israeli law, in the first five years of operation of each asset, in respect of buildings, machinery and equipment used by the Approved Enterprise and the Benefited Enterprise.
c. Conditions for entitlement to the benefits
The Israeli Subsidiary’s entitlement to the benefits described above is subject to its fulfillment of conditions stipulated by the law, rules and regulations published thereunder, and the instruments of approval for the specific investment in an approved enterprise. Failure by the Israeli Subsidiary to comply with these conditions may result in the cancellation of the benefits, in whole or in part, and the Subsidiary may be required to refund the amount of the benefits with interest. The Israeli Subsidiary received a final implementation approval with respect to its “Approved Enterprise” from the Investment Center.
F-35
d. Amendment of the Law for the Encouragement of Capital Investments, 1959
In recent years, several amendments have been made to the Encouragement of Capital Investments Law which have enabled new alternative benefit tracks, subject to certain conditions.
The Encouragement of Capital Investments Law was amended as part of the Economic Policy Law for the years 2011-2012 (amendment 68 to the Encouragement of Capital Investments Law), which was passed by the Israeli Knesset on December 29, 2010. The amendment sets alternative benefit tracks to those currently in effect under the provisions of the Encouragement of Capital Investments Law. On December 29, 2016, Amendment 73 to the Encouragement of Capital Investments Law was published. This amendment sets new benefit tracks, inter alia, “Preferred Technological Enterprise” and “Special Preferred Technological Enterprise” (the “Capital Investments Law Amendment”).
To date, the Company has elected not to have the Capital Investments Law Amendment apply to the Company.
c. Tax losses carried forward to future years
As of December 31, 2021 and 2020, the Company had aggregate NOL carry-forwards equal to approximately $

Significant judgment is required in determining any valuation allowance recorded against deferred tax assets. In assessing the need for a valuation allowance, the Company considered all available evidence, including past operating results, the most recent projections for taxable income, and prudent and feasible tax planning strategies. The Company reassesses its valuation allowance periodically and if future evidence allows for a partial or full release of the valuation allowance, a tax benefit will be recorded accordingly.

Deferred taxes are computed using the tax rates expected to be in effect when those differences reverse.
e. Reconciliation of the theoretical tax expense to actual tax expense
The main reconciling item between the statutory tax rate of the Company and the effective rate is the provision for a full valuation allowance in respect of tax benefits from carry forward tax losses due to the uncertainty of the realization of such tax benefits (see above).
f. Tax assessments
In accordance with the Income Tax Ordinance, as of December 31, 2021, all of Protalix Ltd.’s tax assessments through tax year 2016 are considered final.
