We are a specialty pharmaceutical company focused on our clinically-validated and patent-protected PLxGuard^TM drug delivery platform designed to provide more effective and safer products. The PLxGuard drug delivery platform works by targeting the release of active pharmaceutical ingredients to various portions of the GI tract. We believe this platform has the potential to improve the absorption of many drugs currently on the market or in development, and to reduce the risk of stomach erosions and ulcers associated with certain drugs.

VAZALORE, available in two doses 325 mg and 81 mg, is approved by the U.S. Food and Drug Administration (“FDA”). VAZALORE is a novel formulation of aspirin clinically shown to provide fast, reliable and predictable platelet inhibition for patients with vascular disease and diabetic patients who may be candidates for aspirin therapy as compared to the current standard of care, enteric-coated aspirin. It is also clinically shown to reduce the risk of stomach erosions and ulcers as compared with immediate-release aspirin, after seven days of treatment.

Our commercialization strategy will target the over-the-counter (“OTC”) market, taking advantage of the existing distribution channels for aspirin. We intend to market VAZALORE to the healthcare professional and the consumer through several sales and marketing channels. Our product pipeline also includes other oral NSAIDs using the PLxGuard drug delivery platform that may be developed, including PL1200 Ibuprofen 200 mg and PL1200 Ibuprofen 400 mg, for pain and inflammation in Phase I clinical stage.

Our PLxGuard delivery system uses surface acting lipids, such as phospholipids and free fatty acids, to modify the physiochemical properties of various drugs with a targeted release to select portions of the GI tract. Unlike tablet or capsule polymer coating technologies (e.g., enteric coating), which rely solely on drug release based on pH differences in the GI tract, the PLxGuard delivery system utilizes both the differential pH in the GI tract and the presence of bile acid bicarbonate and pancreatic enzymes in the duodenum to target VAZALORE’s release. The PLxGuard drug delivery platform works by targeting the release of active pharmaceutical ingredients to various portions of the GI tract. We believe this platform has the potential to improve the absorption of many drugs currently on the market or in development, and to reduce the risk of stomach erosions and ulcers associated with certain drugs. This approach is intended to target the release of active pharmaceutical ingredients in the duodenum and decrease their exposure to the stomach, which is more susceptible to NSAID-induced bleeding and ulceration. The PLxGuard drug delivery is a platform technology that we believe may be useful in improving the absorption of many acid labile, corrosive, and insoluble or impermeable drugs.

We believe our PLxGuard drug delivery platform has the potential to improve many already-approved drugs and drugs in development because it may:

The PLxGuard drug delivery platform with our novel formulations using aspirin and ibuprofen have undergone clinical and preclinical testing described below. Other existing or new drugs in development that may benefit from the PLxGuard drug delivery platform will be evaluated either by us or through collaboration agreements with other companies.

Our lead product, VAZALORE 325 mg, has been approved by the FDA for OTC distribution and is the first-ever FDA-approved liquid-filled aspirin capsule. In clinical trials in obese diabetic patients at risk for cardiovascular disease, VAZALORE 325 mg delivered fast, reliable and predictable platelet inhibition consistent with immediate release aspirin. VAZALORE 325 mg provided complete antiplatelet effect with a median time to 99% inhibition of serum Thromboxane B2 of two hours compared with 48 hours for enteric-coated aspirin after three days of treatment. This greater bioavailability translates into consistent and sustained antiplatelet benefits with twice as many patients achieving a complete antiplatelet response after 3 days treatment compared with enteric-coated aspirin. Near complete inhibition of serum Thromboxane B2 (>99%) is a clinically accepted marker for antiplatelet efficacy, which is sometimes referred to as aspirin response. The area under the curve (“AUC”) of plasma concentrations were VAZALORE 325 mg (2,523), immediate release aspirin (1,964) and enteric coated aspirin (456), thus absorption with VAZALORE was 5 times as high as enteric-coated aspirin. The fast and reliable platelet inhibition achieved with VAZALORE 325 mg may be particularly important in the hospital management of acute vascular events such as heart attacks and strokes where platelet inhibition is absolutely critical. VAZALORE 325 mg has also caused significantly fewer erosions and ulcers than immediate release aspirin after seven days of treatment. In clinical trials, VAZALORE resulted in 47% lower risk of erosions or ulcers with an NNT of five and 71% lower risk of ulcers with a number needed to treat (“NNT”) of eight. The lower risk for GI complications can have important benefits including better drug tolerance for the patients (less dyspepsia, bloating, etc.) and potentially less use of stomach acid reducers (antacids, proton pump inhibitors, etc.) in the acute setting. The reduction of adverse gastric events in the acute setting may also be particularly important in the hospital setting where patients with acute vascular events such as heart attacks and strokes are at very high risk for gastric erosions and ulcers due to the stress associated with the episode and the co-administration of other antiplatelet therapies that are standard components of the treatment protocols. Finally, the lower risk of erosions and ulcers after seven days of treatment as compared to immediate release aspirin may also be used to differentiate VAZALORE 325 mg from products intended for use in conditions associated with pain and inflammation, including other aspirin and NSAID products, although significant additional development and clinical testing will need to be performed.

VAZALORE 81 mg is our lower-dose companion product for VAZALORE 325 mg (the two dose forms are sometimes referred to in this Form 10-K together as “VAZALORE”). This product utilizes exactly the same formulation as the 325 mg product (except delivered in a capsule one quarter the size). SNDAs for VAZALORE 325 mg and VAZALORE 81 mg doses were approved by the FDA in February 2021.

We also believe our technology may be used with other selected NSAIDs, such as ibuprofen. We have used the PLxGuard drug delivery platform to create a lipid-based formulation of ibuprofen, PL1200 Ibuprofen 200 mg, for the OTC market, and PL1100 Ibuprofen 400 mg, for prescription doses of ibuprofen. We have OTC and prescription (“Rx”) Investigational New Drug applications (“INDs”) active with the FDA and have demonstrated bioequivalence with the OTC 200 mg dose ibuprofen to support a 505(b)(2) NDA in fasted-state clinical trials at three different doses, 200 mg, 400 mg and 800 mg. Using the PL1200 capsules at prescription doses, we demonstrated potentially better GI tolerability in osteoarthritic patients with equivalent analgesic and anti-inflammatory efficacy, when compared with prescription ibuprofen in a six-week endoscopy pilot clinical trial. PL1200 and PL1100 Ibuprofen may be considered as being in Phase 1 in the FDA approval process and may qualify for the 505(b)(2) NDA path.

We do not own or operate manufacturing facilities for the production of our product candidates, nor do we have plans to develop or own manufacturing operations in the foreseeable future. We currently rely on third-party contract manufacturers for all of our required ingredients and finished products for VAZALORE and other product candidates. We have entered into a Manufacturing Services Agreement with Thermo Fisher Scientific’s Pharma Services (“Thermo Fisher”) business to provide the capabilities to bring VAZALORE to market. We currently employ internal resources to manage our manufacturing contractors. Our agreement with Thermo Fisher includes representations and warranties that Thermo Fisher will perform its services under the agreement in compliance with current Good Manufacturing Practices (“cGMP”). There can be no assurance that VAZALORE or other product candidates, if approved, can be manufactured in sufficient commercial quantities, in compliance with regulatory requirements and at an acceptable cost.

We and our contract manufacturers are and will be subject to extensive government regulation in connection with the manufacture of any pharmaceutical product. We and our contract manufacturers must ensure that all of the processes, methods and equipment are compliant with cGMP and current Good Laboratory Practices (“cGLPs”) for drugs on an ongoing basis, as mandated by the FDA and other regulatory authorities, and conduct extensive audits of vendors, contract laboratories and suppliers.

While we believe that most of the ingredients we require to manufacture VAZALORE are readily available from multiple suppliers and are commonly used in the pharmaceutical industry, some key components are sourced from a limited number of suppliers.

The pharmaceutical industry is characterized by rapidly advancing technologies, intense competition and a strong emphasis of proprietary products. We face competition and potential competition from a number of sources, including pharmaceutical and biotechnology companies, generic drug companies, drug delivery companies and academic and research institutions. We believe the key competitive factors that will affect the development and commercial success of our product candidates include the therapeutic efficacy, safety and tolerability profiles and cost. Many of our competitors have substantially greater financial, technical and human resources than we do, as well as more experience in the development of product candidates, obtaining FDA and other regulatory approvals of products, and the commercialization of those products. Consequently, our competitors may develop products that may be more effective, better tolerated and less costly than our product candidates. Our competitors may also be more successful in manufacturing and marketing their products than we are. We will also face competition in recruiting and retaining qualified personnel and establishing clinical trial sites and patient enrollment in clinical trials.

VAZALORE faces competition from many companies with OTC aspirin products. These include branded products from Bayer AG, Prestige Brands, Inc. (Ecotrin, Goody’s, BC Powder) and Foundation Consumer Healthcare, LLC (St. Joseph) and private label or store brands (CVS, Walgreens). Aspirin is approved in the United States for multiple uses. In addition to cardiovascular disease prevention and treatment, OTC aspirin may be used for the treatment of pain, inflammation and fever. There are two aspirin products for cardiovascular disease prevention that are approved by the FDA for prescription use owned by Innovida Pharmaceutique Inc. (Yosprala) and Espero BioPharma, Inc. (Durlaza) that are to the best of our knowledge not currently marketed in the US. There are a variety of aspirin and NSAID products in various stages of development in the United States and globally that represent potential competition when and if they become approved by the FDA and are commercialized. Companies and academic institutions involved include Takeda Pharmaceutical Company Limited (Takeda), Oxford Pharmascience Group Plc, Antibe Therapeutics Inc. and The City College of New York. VAZALORE and other pain and inflammation product candidates such as PL1200 Ibuprofen will face competition from many firms. These include OTC and prescription products. Major competitors include Pfizer Inc. (Advil), Johnson & Johnson (MotrinIB, Tylenol), Bayer AG (Aleve) and private label or store brands (CVS, Walgreens).

The aspirin market is currently predominantly composed of generic products either branded (e.g. Bayer) or private label (e.g. CVS). VAZALORE is the only liquid-filled aspirin capsule product to be approved by the FDA. VAZALORE 325 mg went through a different regulatory approval process than the current OTC aspirin products being marketed in the US. VAZALORE 325 mg was approved under the 505(b)(2) NDA process and, when launched, is expected to be the only OTC available aspirin-based product that successfully passed this rigorous process. We believe the clinical trials that demonstrated better efficacy and safety will assist us in differentiating VAZALORE from the competition. Other product candidates will undergo clinical trials to provide differentiation as part of their product development and commercialization.

Our success depends, in part, upon our ability to protect our core novel technology. To establish and protect our proprietary rights we rely on a combination of patents, patent applications, trademarks, copyrights, trade secrets and know-how, license agreements, confidentiality procedures, non-disclosure agreements with third parties, employee disclosure and invention assignment agreements, and other contractual rights.

We have developed our own patent applications, some of which have been issued and others, if issued with claims as filed, will provide patent protection for VAZALORE 325 mg and 81 mg, other NSAID products and will broaden the opportunity for new products to include many different drug classes. In the United States we have six patents issued from the “pH dependent carriers for targeted release of pharmaceuticals along the gastrointestinal tract, compositions therefrom and making and using same” family consisting of U.S. patent numbers 9216150, 9226892, 9730884, 10179104, 10646431 and 10786444 expiring on September 29, 2032, in China issued number ZL201280058596X expiring on September 28, 2032, in Hong Kong issued number HK1200098 expiring September 29, 2032, in Australia issued number 2012315545 expiring September 29, 2032 and in Mexico we have issued patents numbered 340951 and 356017 expiring on September 29, 2032. In Japan we have patent number 6368645 issued expiring September 29, 2032 and have received a Notice of Allowance for additional claims. In South Korea, we have patent numbers 10-2162901 and 10-2188840 expiring September 29, 2032 and have received a Notice of Allowance for additional claims. We have pending applications in Europe, Canada and India, a which, if issued, are expected to provide patent protection through September 29, 2032.

We have filed in March 2020 a new patent application entitled Pharmaceuticals Carriers Capable of pH Dependent Reconstitution and Methods for Making and Using Same in the United States and may file in other international jurisdictions. If issued with claims as filed this will provide additional patent protection for VAZALORE 325 mg and 81 mg, other NSAID products and new products to include many different drug classes with expiration in March 2041.

On January 8, 2003, we entered into a worldwide, exclusive license agreement with The Board of Regents of the University of Texas System (“UT”), as described in more detail in the section herein titled “License Agreements—UT License Agreement”, which was amended, restated on December 11, 2009, and subsequently amended on April 15, 2011 and on December 17, 2011 (as amended, the “UT License Agreement”). The patents in-licensed under the UT License Agreement constitute a part of our intellectual property. This family of patents includes composition of matter, methods of manufacturing and methods of treatment that provide protection for VAZALORE, PL1200 Ibuprofen and other NSAID product candidates in the United States and global markets. The following is a summary of the patents in-licensed under the UT License Agreement and their respective expiration dates:

U.S. patent numbers 10646431 and 10786444 “pH dependent carriers for targeted release of pharmaceuticals along the gastrointestinal tract, compositions therefrom and making and using same” are listed in the FDA Orange Book. As new patents are issued relative to FDA approved products such as VAZALORE 325 mg and 81 mg, they will be added to the Orange Book and, as new products are approved by the FDA, the relevant patents will be added to the Orange Book. The Orange Book lists patents that protect each drug. Patent listings and use codes are provided by the drug application owner, and the FDA is obliged to list them. In order for a generic drug manufacturer to win approval of a drug under the Drug Price Competition and Patent Term Restoration Act of 1984 (the “Hatch-Waxman Act”), the generic manufacturer must certify that they will not launch their generic pharmaceutical product until after the expiration of the Orange Book-listed patent, or that the patent is invalid, unenforceable, or that the generic product will not infringe the listed patent.

The term of individual patents depends upon the legal term for patents in the countries in which they are granted. In most countries, including the United States, the patent term is generally 20 years from the earliest claimed filing date of a non-provisional patent application in the applicable country. In the United States, a patent’s term may, in certain cases, be lengthened by patent term adjustment, which compensates a patentee for administrative delays by the U.S. Patent and Trademark Office (“USPTO”) in examining and granting a patent or may be shortened if a patent is terminally disclaimed over a commonly owned patent or a patent naming a common inventor and having an earlier expiration date. The Hatch-Waxman Act permits a patent term extension of up to five years beyond the expiration date of a U.S. patent as partial compensation for the length of time the drug is under regulatory review.

On January 8, 2003, we entered into the UT License Agreement. The patents in-licensed under this agreement constitute an important part of our intellectual property. This family of patents includes composition of matter, methods of manufacturing and methods of treatment that provide protection for VAZALORE, PL1200 Ibuprofen and other NSAID product candidates in the United States and in a number of global markets. Pursuant to the UT License Agreement, UT granted us an exclusive license under its patents and know-how related to their NSAID-phospholipid technology to develop and commercialize NSAID products for use anywhere in the world. Certain of the technology was developed with government funding, and the exclusivity of our license is therefore subject to certain retained rights of the U.S. federal government. We are responsible for the development and commercialization of the licensed products under the agreement. The UT License Agreement is in effect as long as the patents are valid and we may terminate the UT License Agreement at our option with appropriate notice. Also, if we fail to actively attempt to commercialize licensed products for a specific period of time, UT may have the option to terminate or limit the exclusivity of the license in certain territories. Specifically, Section 4.6 of the UT License Agreement provides that “Reasonable commercial diligence shall require that the Company . . . . [o]n or before September 8, 2013, Sell or offer for Sale a Licensed Product.” While we believe that we have exercised reasonable commercial diligence to actively attempt such commercialization, we have not yet successfully commercialized a licensed product. As such, UT may have the option to terminate the UT License Agreement, or to limit the exclusivity of the license in certain territories. The UT License Agreement provides for milestone payments related to the first product to obtain regulatory approval to sell a licensed product, which milestone payments have been paid. The UT License Agreement provides for future potential milestone payments based upon the aggregate revenue from the sale of all licensed products in aggregate totaling $350,000. These milestones may be triggered in the next twelve months depending on the timing of the launch of VAZALORE. In addition to the milestone payments, we will owe a royalty on the net sales of the licensed products. The amount of the royalty depends upon who is selling the product. Should we commercialize a product ourselves there is a running royalty obligation in the low single digit range based upon net sales. If a product is commercialized by another company under a sublicense agreement with us, then UT receives a share of consideration received by us that is in the low double-digit range. There is a minimum annual royalty payment obligation. We are responsible for the prosecution and maintenance of the licensed patents at our expense and for the prosecution and control of any action for infringement related to any product that does, or may, compete with one of our marketed licensed products and any claim within a licensed patent that covers or relates to such marketed licensed product.

Government authorities in the United States, at the federal, state and local level, in the European Union, and in other countries and jurisdictions extensively regulate, among other things, the research, development, testing, manufacture, including any manufacturing changes, packaging, storage, recordkeeping, labeling, advertising, promotion, distribution, marketing, import and export of pharmaceutical products such as those we are developing. The processes for obtaining regulatory approvals in the United States and in foreign countries and jurisdictions, along with subsequent compliance with applicable statutes and regulations, require the expenditure of substantial time and financial resources.

In the United States, the FDA regulates drugs under the federal Food, Drug, and Cosmetic Act (the “FDCA”), implementing regulations and other federal and state statutes and regulations. The process of obtaining regulatory approvals and the subsequent compliance with appropriate federal, state, local 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 a variety of administrative or judicial sanctions, such as the FDA’s refusal to approve pending NDAs, withdrawal of an approval, imposition of a clinical hold, issuance of untitled or warning letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement or civil or criminal penalties.

The process required by the FDA before a drug may be marketed in the United States generally involves the following:

Preclinical studies include laboratory evaluation of product chemistry, toxicity and formulation, as well as animal studies to assess a product’s potential safety and efficacy. An IND sponsor must submit the results of the preclinical tests, together with manufacturing information, analytical data and any available clinical data or literature, among other things, to the FDA as part of an IND. Some preclinical testing may continue even after the IND is submitted. An IND automatically becomes effective 30 days after receipt by the FDA, unless during such 30-day period the FDA raises concerns or questions related to one or more proposed clinical trials and places the trial on a clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. As a result, submission of an IND may not result in the FDA allowing clinical trials to commence.

Clinical trials involve the administration of the investigational new drug to human subjects under the supervision of qualified investigators in accordance with cGCP requirements, which include the requirement that all research subjects provide their informed consent (assent, if applicable) in writing for their participation in any clinical trial. Clinical trials are conducted under protocols detailing, among other things, the objectives of the study, the parameters to be used in monitoring safety and the effectiveness criteria to be evaluated. A protocol for each clinical trial and any subsequent protocol amendments must be submitted to the FDA as part of the IND. In addition, an IRB at each institution participating in the clinical trial must review and approve the plan for any clinical trial before it commences at that institution. Information about certain clinical trials must be submitted within specific timeframes to the National Institutes of Health for public dissemination on their ClinicalTrials.gov website.

Human clinical trials are typically conducted in three sequential phases, which may overlap or be combined:

Progress reports detailing the results of the clinical trials must be submitted at least annually to the FDA and more frequently if serious adverse events occur. Phase 1, Phase 2 and Phase 3 clinical trials may not be completed successfully within any specified period, or at all. Furthermore, the sponsor may suspend or terminate a clinical trial at any time on various grounds, including a finding that the clinical trial patients are being exposed to an unacceptable health risk. The FDA may order the temporary, or permanent, discontinuation of a clinical trial at any time, or impose other sanctions, if it believes that the clinical trial either is not being conducted in accordance with FDA requirements or presents an unacceptable risk to the clinical trial patients. 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 drug has been associated with unexpected serious harm to patients.

Assuming successful completion of the required clinical testing, the results of the preclinical and clinical studies, together with detailed information relating to the product’s chemistry, manufacture, controls and proposed labeling, among other things, are submitted to the FDA as part of an NDA requesting approval to market the product for one or more indications. In most cases, the submission of an NDA is subject to a substantial application user fee, which is typically increased annually. Under the new Prescription Drug User Fee Act guidelines that are currently in effect, the FDA has a goal of ten months from the date of the FDA’s acceptance for filing of a standard non-priority NDA to review and act on the submission.

As a condition of NDA approval, the FDA also may require submission of a risk evaluation and mitigation strategy (“REMS”) plan to mitigate any identified or suspected serious risks. The REMS plan could include medication guides, physician communication plans, assessment plans and elements to assure safe use, such as restricted distribution methods, patient registries or other risk minimization tools.

The FDA conducts a preliminary review of all NDAs within the first 60 days after submission, before accepting them for filing, to determine whether they are sufficiently complete to permit substantive review. The FDA may request additional information rather than accept an NDA for filing. In this event, the application must be resubmitted with the additional information. The resubmitted application is also subject to review before the FDA accepts it for filing. Once the submission is accepted for filing, the FDA begins an in-depth substantive review. The FDA reviews an NDA to determine, among other things, whether the drug is safe and effective and whether the facility in which it is manufactured, processed, packaged or held meets standards designed to assure the product’s continued safety, quality and purity. The FDA may refer an application for a novel drug to an advisory committee, which is a panel of independent experts, including clinicians and other scientific experts, that reviews, evaluates and provides a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions.

Before approving an NDA, the FDA typically will inspect the facility or facilities where the product is manufactured, which is not under the control of the product sponsor. The FDA will not approve an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. Additionally, before approving an NDA, the FDA will typically inspect one or more clinical sites to assure compliance with cGCP.

After the FDA evaluates the NDA and the manufacturing facilities, it issues either an approval letter or a complete response letter. A complete response letter generally outlines the deficiencies in the submission and may require substantial additional testing, or information, in order for the FDA to reconsider the application. The FDA has committed to reviewing such resubmissions in two or six months depending on the type of information included. Even with submission of this additional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval. If, or when, those conditions have been met to the FDA’s satisfaction, the FDA will issue an approval letter. An approval letter authorizes commercial marketing of the drug with specific prescribing information for specific indications.

Even if the FDA approves a product, it may limit the approved indications for use for the product, require that contraindications, warnings or precautions be included in the product labeling, require that post-approval studies, including Phase 4 clinical trials, be conducted to further assess a drug’s safety after approval, require testing and surveillance programs to monitor the product after commercialization, or impose other conditions, including distribution restrictions or other risk management mechanisms, which can materially affect the potential market and profitability of the product. The FDA may prevent or limit further marketing of a product based on the results of post-marketing studies or surveillance programs. After approval, some types of changes to the approved product, such as adding new indications, manufacturing changes and additional labeling claims, are subject to further testing requirements and FDA review and approval.

Drugs manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including, among other things, requirements relating to recordkeeping, periodic reporting, product sampling and distribution, advertising and promotion and reporting of adverse experiences with the product. After approval, most changes to the approved product, such as adding new indications or other labeling claims, are subject to prior FDA review and approval. There also are continuing, annual user fee requirements for any marketed products and the establishments at which such products are manufactured, as well as new application fees for supplemental applications with clinical data.

The FDA may impose a number of post-approval requirements as a condition of approval of an NDA. For example, the FDA may require post-marketing testing, including Phase 4 clinical trials, and surveillance to further assess and monitor the product’s safety and effectiveness after commercialization.

In addition, drug manufacturers and other entities involved in the manufacture and distribution of approved drugs are required to register their establishments with the FDA and state agencies, and are subject to periodic unannounced inspections by the FDA and these state agencies to determine compliance with cGMP requirements. Changes to the manufacturing process are strictly regulated and often require prior FDA approval before being implemented. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting and documentation requirements upon the sponsor and any third-party manufacturers that the sponsor may decide to use. Accordingly, manufacturers must continue to expend significant time, money and effort in the area of production and quality control to maintain cGMP compliance.

Once an approval is granted, the FDA may withdraw the approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety information, imposition of post-market studies or clinical trials to assess new safety risks, or imposition of distribution or other restrictions under a REMS program. Other potential consequences include, among other things:

The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Drugs may be promoted only for the approved indications and in accordance with the provisions of the approved label, although doctors may prescribe drugs for off-label purposes. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability. In addition, the distribution of prescription pharmaceutical products is subject to the Prescription Drug Marketing Act which regulates the distribution of drugs and drug samples at the federal level, and sets minimum standards for the registration and regulation of drug distributors by the states. In addition, prescription drug manufacturers in the United States must comply with applicable provisions of the Drug Supply Chain Security Act and provide and receive product tracing information, maintain appropriate licenses, ensure they only work with other properly licensed entities, and have procedures in place to identify and properly handle suspect and illegitimate products.

Most drug products obtain FDA marketing approval pursuant to an NDA or an abbreviated new drug application (“ANDA”). A third alternative is a special type of NDA, commonly referred to as a Section 505(b)(2) NDA, which enables the applicant to rely, in part, on FDA’s prior findings of safety and/or effectiveness for a similar product or published literature in support of its application.

505(b)(2) NDAs often provide an alternate path to FDA approval for new or improved formulations or new uses of previously approved products. Section 505(b)(2) permits the filing of an NDA where at least some of the information required for approval comes from studies not conducted by, or for, the applicant and for which the applicant has not obtained a right of reference. If the 505(b)(2) applicant can establish that reliance on the FDA’s prior findings of safety and/or effectiveness is scientifically appropriate, it may eliminate the need to conduct certain preclinical or clinical studies of the new product. The FDA may also require companies to perform additional studies or measurements to support the change from the approved product. The FDA may then approve the new product candidate for all, or some, of the indications for which the referenced product has been approved, as well as for any new indication sought by the Section 505(b)(2) applicant.

Marketing exclusivity provisions under the FDCA can delay the submission or the approval of certain applications for competing products. The FDCA provides a five-year period of non-patent exclusivity within the United States to the first applicant to gain approval of an NDA for a new chemical entity. A drug is a new chemical entity (“NCE”) if the FDA has not previously approved any other new drug containing the same active moiety, which is the molecule or ion responsible for the action of the drug substance. During the NCE exclusivity period, the FDA may not accept for review an ANDA or a 505(b)(2) NDA submitted by another company that references the previously approved drug. However, an ANDA or 505(b)(2) NDA may be submitted after four years if it contains a certification of patent invalidity or non-infringement (a Paragraph IV certification). If the ANDA or 505(b)(2) applicant has provided a Paragraph IV certification to the FDA, the applicant must also send notice of the Paragraph IV certification to the NDA and patent holders once the ANDA has been accepted for filing by the FDA. The NDA and patent holders may then initiate a patent infringement lawsuit in response to the notice of the Paragraph IV certification. The filing of a patent infringement lawsuit within 45 days of the receipt of a Paragraph IV certification automatically prevents the FDA from approving the ANDA until the earlier of 30 months, expiration of the patent, settlement of the lawsuit, or a decision in the infringement case that is favorable to the ANDA applicant.

The FDCA also provides three years of marketing exclusivity for an NDA, 505(b)(2) NDA or supplement to an existing NDA or 505(b)(2) NDA if new clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant, are deemed by the FDA to be essential to the approval of the application, for example, for new indications, dosages, strengths or dosage forms of an existing drug. This three-year exclusivity covers only the conditions of use associated with the new clinical investigations and, as a general matter, does not prohibit the FDA from approving ANDAs or 505(b)(2) NDAs for generic versions of the original, unmodified drug product. Five-year and three-year exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would be required to conduct or obtain a right of reference to all of the preclinical studies and adequate and well-controlled clinical trials necessary to demonstrate safety and effectiveness.

OTC drugs can be brought to market via two routes: the NDA approval process and the OTC monograph process. A drug product is eligible to be brought to market via the OTC monograph process if it is not a new drug, and the drug product meets the FDA’s established conditions for general recognition of safety and effectiveness (“GRASE”). The OTC drug monographs are a kind of “rule book” of conditions for each therapeutic category covering acceptable ingredients, uses (indications), doses, formulations, labeling, and testing.

The OTC Drug Review is a three-phase public rulemaking process established by the FDA to evaluate the safety and effectiveness of OTC drug products marketed in the United States prior to May 11, 1972. The three-phase rulemaking process can be summarized as follows:

If a product deviates from the conditions under the TFM or final monograph and was not marketed before May 1972, then the drug product is considered a new drug and requires an NDA to be legally marketed. Aspirin was classified into the therapeutic class for Internal Analgesic, Antipyretic, and Antirheumatic Drug Products (“IAAA”). The ANPR was published in 1977, and in 1988, the FDA published the TFM for IAAA. The IAAA TFM recommends appropriate labeling, including therapeutic indications, dosage instructions, and warnings about side effects and ways of preventing misuse. Although it has been updated and amended since its original publication, the IAAA monograph has not been finalized.

Differences between the NDA approval process and the OTC monograph process are listed below.

When VAZALORE is commercialized, we believe it will be the only NDA-approved OTC aspirin product available. Approval of the VAZALORE NDA granted VAZALORE labeling similar to that of monograph aspirin products.

Although the IAAA TFM has not been finalized for OTC use, final regulations for the professional labeling of aspirin were published in 1988. Professional labeling is labeling that provides specific information to health professionals for uses not included in OTC drug labeling. Professional labeling can be provided solely to healthcare professionals. Professional labeling may not be used on consumer products or on consumer-directed labeling. Under the IAAA regulations for professional labeling of aspirin, patients can only use aspirin for cardiovascular-related uses when directed to do so by a physician.

Since 1971, the FDA and the Federal Trade Commission (the “FTC”) have had a Memorandum of Understanding in place, which dictates that the FDA has primary responsibility over OTC drug labeling, while the FTC has primary responsibility over OTC drug advertising.

For an NDA-approved product, OTC labeling, including the labeling on the box, must be submitted to the FDA for review and approval prior to distribution. As indicated above, this is different from monograph products, which are not subjected to the FDA’s labeling review and approval processes prior to launching to market. Advertising for OTC products is under the purview of the FTC. Promotional material (including print, radio, and/or TV) is not required to be submitted to the FTC prior to distribution, unlike Rx promotional materials submitted to the FDA.

Under FTC regulations, claims in advertisements, including OTC medicine advertisements, must be truthful and cannot be misleading or unfair.

Advertisers must have substantiation that all objective express and implied claims in advertising are true before making the claims. The standard for substantiation of health claims is “competent and reliable scientific evidence.” For drug claims, competent and reliable scientific evidence generally has been interpreted as requiring at least one or two adequate and well-controlled human clinical studies of the product, or of an essentially equivalent product, that conform to acceptable designs and protocols and whose results, when considered in light of the entire body of relevant and reliable scientific evidence, are sufficient to substantiate that the representation is true.

Beyond FTC regulation of advertising, industry self-regulation plays an important role. The National Advertising Division (“NAD”) of the Council of Better Business Bureaus reviews advertising complaints by competitors. NAD generally applies the same standard as the FTC. If NAD determines that the substantiation does not support the claims or that it is otherwise false and misleading, it will recommend that the advertiser revise or discontinue the advertisement. If the advertiser does not agree to do so, NAD will forward the case to the FTC or the FDA for review.

In order to market any product outside of the United States, we would need to comply with numerous and varying regulatory requirements of other countries and jurisdictions regarding quality, safety and efficacy and governing, among other things, clinical trials, marketing authorization, commercial sales and distribution of our products. The cost of establishing a regulatory compliance system for numerous varying jurisdictions can be very significant. Whether or not we obtain FDA approval for a product, we would need to obtain the necessary approvals by the comparable foreign regulatory authorities before we can commence clinical trials or marketing of the product in foreign countries and jurisdictions. Although many of the issues discussed above with respect to the United States apply similarly in the context of the European Union, the approval process varies between countries and jurisdictions and can involve additional product testing and additional administrative review periods. The time required to obtain approval in other countries and jurisdictions might differ from and be longer than that required to obtain FDA approval. Regulatory approval in one country or jurisdiction does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country or jurisdiction may negatively impact the regulatory process in others.

Pursuant to the European Clinical Trials Directive, a system for the approval of clinical trials in the European Union has been implemented through national legislation of the member states. Under this system, we must obtain approval from both the competent national authority of a European Union member state in which the clinical trial is to be conducted, and a favorable opinion from the competent ethics committee. Our clinical trial application must be accompanied by an investigational medicinal product dossier with supporting information prescribed by the European Clinical Trials Directive and corresponding national laws of the member states and further detailed in applicable guidance documents.

To obtain marketing approval of a drug under European Union regulatory systems, we may submit a Marketing Authorization Application (“MAA”) either under a centralized or decentralized procedure. The centralized procedure provides for the grant of a single marketing authorization by the European Commission that is valid for all European Union member states. The centralized procedure is compulsory for specific products, including medicines produced by certain biotechnological processes, products designated as orphan medicinal products, advanced therapy products and products with a new active substance indicated for the treatment of certain diseases. For products with a new active substance indicated for the treatment of other diseases and products that are highly innovative or for which a centralized process is in the interest of patients, the centralized procedure may be optional. Under the centralized procedure, the Committee for Medicinal Products for Human Use (the “CHMP”) established at the European Medicines Agency (the “EMA”) is responsible for conducting the initial assessment of a drug. The CHMP also is responsible for several post-authorization and maintenance activities, such as the assessment of modifications or extensions to an existing marketing authorization. Under the centralized procedure in the European Union, the maximum timeframe for the evaluation of an MAA is 210 days, excluding clock stops, when additional information or written or oral explanation is requested by the CHMP but has not yet been provided. Accelerated evaluation might be granted by the CHMP in exceptional cases, when a medicinal product is of major interest from the point of view of public health and in particular from the viewpoint of therapeutic innovation. In this circumstance, the EMA ensures that the opinion of the CHMP is given within 150 days.

The decentralized procedure is available to applicants who wish to market a product in various European Union member states where such product has not previously received marketing approval in any European Union member state. The decentralized procedure provides for approval by one or more other, or concerned, member states of an assessment of an application performed by one member state designated by the applicant, known as the reference member state. Under this procedure, an applicant submits an application based on identical dossiers and related materials, including a draft summary of product characteristics, and draft labeling and package leaflet, to the reference member state and concerned member states. The reference member state prepares a draft assessment report and drafts of the related materials within 120 days after receipt of a valid application. Within 90 days of receiving the reference member state’s assessment report and related materials, each concerned member state must decide whether to approve the assessment report and related materials.

If a member state cannot approve the assessment report and related materials on the grounds of potential serious risk to public health, the disputed points are subject to a dispute resolution mechanism and may eventually be referred to the European Commission, whose decision is binding on all member states.

In the European Union, new chemical entities qualify for eight years of data exclusivity upon marketing authorization and an additional two years of market exclusivity. This data exclusivity, if granted, prevents regulatory authorities in the European Union from referencing the innovator’s data to assess a generic (abbreviated) application for eight years, after which generic marketing authorization can be submitted, and the innovator’s data may be referenced, but not approved for two years. The overall ten-year period will be extended to a maximum of eleven years if, during the first eight years of those ten years, the marketing authorization holder obtains an authorization for one or more new therapeutic indications which, during the scientific evaluation prior to their authorization, are held to bring a significant clinical benefit in comparison with existing therapies. Even if a compound is considered to be a new chemical entity and the sponsor is able to gain the prescribed period of data exclusivity, another company nevertheless could also market another version of the drug if such company can complete a full MAA with a complete database of pharmaceutical test, preclinical tests and clinical trials and obtain marketing approval of its product.

Significant uncertainty exists as to the coverage and reimbursement status of any drug products for which we may obtain regulatory approval. Sales of any of our product candidates, if approved, will depend, in part, on the extent to which the costs of the products will be covered by third-party payors, including government health programs such as Medicare and Medicaid, commercial health insurers and managed care organizations. The process for determining whether a third-party payor will provide coverage for a drug product typically is separate from the process for setting the price of a drug product or for establishing the reimbursement rate that a payor will pay for the drug product once coverage is approved. Third-party payors may limit coverage to specific drug products on an approved list, also known as a formulary, which might not include all of the approved drugs for a particular indication.

In order to secure coverage and reimbursement for any product that might be approved for sale, we may need to conduct expensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of the product, in addition to the costs required to obtain FDA or other comparable regulatory approvals. Whether or not we conduct such studies, our product candidates may not be considered medically necessary or cost-effective. A third-party payor’s decision to provide coverage for a drug product does not imply that an adequate reimbursement rate will be approved. Third party reimbursement may not be sufficient to enable us to maintain price levels high enough to realize an appropriate return on our investment in product development.

The containment of healthcare costs has become a priority of federal, state and foreign governments, and the prices of drugs have been a focus in this effort. Third-party payors are increasingly challenging the prices charged for medical products and services, examining the medical necessity and reviewing the cost-effectiveness of drug products and medical services and questioning safety and efficacy. If these third-party payors do not consider our products to be cost-effective compared to other available therapies, they may not cover our products after FDA approval or, if they do, the level of payment may not be sufficient to allow us to sell our products at a profit. The U.S. government, state legislatures and foreign governments have shown significant interest in implementing cost-containment programs to limit the growth of government-paid healthcare costs, including price controls, restrictions on reimbursement and requirements for substitution of generic products for branded prescription drugs. Adoption of such controls and measures, and tightening of restrictive policies in jurisdictions with existing controls and measures, could limit payments for pharmaceuticals such as our drug product candidates and could adversely affect our net revenue and results.

Pricing and reimbursement schemes vary widely from country to country. Some countries provide that drug products may be marketed only after a reimbursement price has been agreed. Some countries may require the completion of additional studies that compare the cost-effectiveness of a particular product candidate to currently available therapies. For example, the European Union provides options for its member states to restrict the range of drug products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. European Union member states may approve a specific price for a drug product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the drug product on the market. Other member states allow companies to fix their own prices for drug products, but monitor and control company profits. The downward pressure on healthcare costs in general, particularly prescription drugs, has become 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 competitive pressure that may reduce pricing within a country. Any country that has price controls or reimbursement limitations for drug products may not allow favorable reimbursement and pricing arrangements for any of our products.

The marketability of any products for which we receive regulatory approval for commercial sale may suffer if the government and third-party payors fail to provide adequate coverage and reimbursement. In addition, emphasis on managed care in the United States has increased and we expect will continue to increase the pressure on drug pricing. Coverage policies, third-party reimbursement rates and drug pricing regulation may change at any time. In particular, the Patient Protection and Affordable Care Act of 2010, as amended by the Health Care and Education Reconciliation Act of 2010, which we collectively refer to as the Affordable Care Act (“ACA”), contains provisions that have the potential to substantially change healthcare financing, including impacting the profitability of drugs. For example, the ACA revised the methodology by which rebates owed by manufacturers to the state and federal government for covered outpatient drugs under the Medicaid Drug Rebate Program, extended the Medicaid Drug Rebate Program to utilization of prescriptions of individuals enrolled in Medicaid managed care organizations and subjected manufacturers to new annual fees and taxes for certain branded prescription drugs. Even if favorable coverage and reimbursement status is attained for one or more products for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

Healthcare providers, physicians and third-party payors play a primary role in the recommendation and prescribing of any product candidates for which we may obtain marketing approval. Our business operations and arrangements with investigators, healthcare professionals, consultants, third-party payors and customers may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations. These laws may constrain the business or financial arrangements and relationships through which we research, market, sell and distribute our products that obtain marketing approval. Restrictions under applicable federal and state healthcare laws and regulations, include, but are not limited to, the following:

Some state laws require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government in addition to requiring drug manufacturers to report information related to payments to physicians and other healthcare providers or marketing expenditures. State and foreign laws also govern the privacy and security of health information in some circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations will involve substantial costs. It is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and/or administrative penalties, damages, fines, disgorgement, exclusion from government funded healthcare programs, such as Medicare and Medicaid, and the curtailment or restructuring of our operations. If any of the physicians or other providers or entities with whom we expect to do business are found to be not in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs.

The Foreign Corrupt Practices Act (the “FCPA”) prohibits any U.S. individual or business from paying, offering or authorizing payment or offering of anything of value, directly or indirectly, to any foreign official, political party or candidate for the purpose of influencing any act or decision of the foreign entity in order to assist the individual or business in obtaining or retaining business. The FCPA also obligates companies whose securities are listed in the United States to comply with accounting provisions requiring us to maintain books and records that accurately and fairly reflect all transactions of the Company, including international subsidiaries, and to devise and maintain an adequate system of internal accounting controls for international operations.

As we pursue international licensing and sales arrangements outside the United States, we will be heavily regulated and expect to have significant interaction with foreign officials. Additionally, in many countries outside the United States, the health care providers who prescribe human pharmaceuticals are employed by the government and the purchasers of human pharmaceuticals are government entities; therefore, our interactions with these prescribers and purchasers would be subject to regulation under the FCPA.

In addition to the U.S. application and enforcement of the FCPA, the various jurisdictions in which we operate and supply our products have laws and regulations aimed at preventing and penalizing corrupt and anticompetitive behavior. In recent years, several jurisdictions, including China, Brazil, and the United Kingdom, have enhanced their laws and regulations in this area, increased their enforcement activities, and/or increased the level of cross-border coordination and information sharing.

As of December 31, 2020, we had 11 employees, of which 8 are full time employees. Of these full-time employees, one works on research and development and clinical operations and seven work in sales, marketing, management and administration. We also use the services of numerous outside consultants in business and scientific matters. None of our employees are represented by a labor union or covered by collective bargaining agreements. We consider our relationship with our employees to be good.

Our third-party manufacturers’ activities and our own activities may involve the controlled storage, use and disposal of hazardous materials, including the components of our pharmaceutical product candidates, test samples and reagents, biological materials and other hazardous compounds. We and our manufacturers are subject to federal, state, local and foreign laws and regulations governing the use, generation, manufacture, storage, handling and disposal of these hazardous materials. We currently carry no insurance specifically covering environmental claims relating to the use of hazardous materials. Although we believe that our safety procedures for handling and disposing of these materials and waste products comply with the standards prescribed by these laws and regulations, we cannot eliminate the risk of accidental injury or contamination from the use, storage, handling or disposal of hazardous materials. In the event of an accident, state or federal or other applicable authorities may curtail our use of these materials and/or interrupt our business operations. In addition, if an accident or environmental discharge occurs, or if we discover contamination caused by prior operations, including by prior owners and operators of properties we acquire, we could be liable for cleanup obligations, damages and fines. If such unexpected costs are substantial, this could significantly harm our financial condition and results of operations.

We were originally incorporated in Texas in 2002 and re-incorporated in Delaware in 2015. Our principal executive offices are located at 9 Fishers Lane, Suite E, Sparta, NJ 07871, and our telephone number is (973) 409-6541. Our website address is www.plxpharma.com. We have not incorporated by reference into this Form 10-K the information in, or that can be accessed through, our website and you should not consider it to be a part of this Form 10-K.

On April 19, 2017, Dipexium Acquisition Corp., a Delaware corporation (“Merger Sub”) and a wholly-owned subsidiary of Dipexium Pharmaceuticals, Inc., a Delaware corporation (“Dipexium”), merged with and into PLx Pharma Inc., a privately-held Delaware corporation (“Old PLx”), pursuant to the terms of that certain Agreement and Plan of Merger and Reorganization dated as of December 22, 2016 by and among Dipexium, Merger Sub and Old PLx (the “Merger”). As part of the Merger, Dipexium was re-named PLx Pharma Inc. and Old PLx was re-named PLx Opco Inc. Following completion of the Merger, Old PLx became a wholly-owned subsidiary of the Company. Since the completion of the Merger, the business we have conducted has been primarily the business of Old PLx.

Investing in our common stock involves a high degree of risk. We have described below a number of risk factors which, in addition to uncertainties, risks and other information presented elsewhere in this Form 10-K, including our consolidated financial statements and notes thereto, may adversely affect our business, operating results and financial condition. The uncertainties and risks enumerated below, as well as those presented elsewhere in this Form 10-K, should be considered carefully in evaluating the Company, our business and the value of our securities. If any of the following risks actually occur, our business, financial condition, results of operations and future prospects could be materially and adversely affected. Please also read carefully the section entitled “Information Regarding Forward-Looking Statements” included in this Form 10-K.

We have not yet generated significant revenues, have a limited operating history, have incurred operating losses in each year since our inception and anticipate that we will continue to incur significant losses for the foreseeable future, and if we are unable to achieve and sustain profitability, the market value of our common stock will likely decline.

We have not generated any revenue from the sale of products, have generated minimal revenue from grant activities, and have incurred operating losses since we commenced operations. The Company’s operating loss for the year ended December 31, 2020 was $13.5 million. As of December 31, 2020, we had an accumulated deficit of approximately $102.1 million. We expect to continue to incur significant expenses and increasing operating losses for the foreseeable future as we continue the development and commercialization of VAZALORE and our other product candidates. Our expenses will also increase substantially if and when we:

Even if we do generate revenues, we may never achieve profitability. If we do achieve profitability in the future, we may not be able to sustain profitability in subsequent periods. Our prior losses, combined with expected future losses, have had and will continue to have an adverse effect on our stockholders’ equity and working capital. If we are unable to achieve and sustain profitability, the market value of our common stock will likely decline. Because of the numerous risks and uncertainties associated with developing biopharmaceutical products, we are unable to predict the extent of any future losses or when, if ever, we will become profitable.

We may need additional funding. If we are unable to raise capital when needed, we could be forced to delay, reduce or terminate our operations or commercialization efforts.

As of December 31, 2020, we had working capital of approximately $19.4 million and cash and cash equivalents of approximately $22.4 million. We anticipate that we may need to raise additional financing in the future to fund our operations.

We may obtain additional financing through public or private equity offerings, debt financings (including related-party financings), a credit facility or strategic collaborations. On August 9, 2017, the Company entered into a Loan and Security Agreement with Silicon Valley Bank (“SVB”) that provided for a Term Loan Facility (the “Term Loan Facility” and all amounts borrowed thereunder, the “Term Loan”). Under the Term Loan Facility, the Company borrowed an initial amount of $7.5 million, and had the right to borrow an additional $7.5 million on or before December 31, 2018, provided that the Company first obtained (a) net new capital of not less than $20,000,000 and (ii) FDA approval for the 81 mg formulation of VAZALORE, the Company’s lead product. The Company did not satisfy the requirements for the additional $7.5 million by the December 31, 2018 deadline. The Company made a final payment on the Term Loan Facility on February 9, 2021.

On December 20, 2018, the Company entered into a Purchase Agreement (the “Series A Purchase Agreement”) pursuant to which the Company agreed to issue 15,000 shares of Series A Convertible Preferred Stock (the “Series A Preferred Stock”) to certain investors for gross proceeds of $15 million, subject to stockholder approval which was received on February 19, 2019, and the financing was completed on February 20, 2019 (the “Series A Private Placement”).

On March 12, 2020, the Company entered into a Purchase Agreement pursuant to which the Company agreed to issue 8,000 shares of Series B Convertible Preferred Stock (the “Series B Preferred Stock”) to certain investors for gross proceeds of $8 million, subject to stockholder approval which was received on May 15, 2020, and the financing was completed on May 15, 2020 (the “Series B Private Placement”). On November 16, 2020, the Company entered into a Securities Purchase Agreement pursuant to which the Company agreed to issue an aggregate of 4,755,373 immediately separable units (the “Units”), with each Unit being comprised of (i) one share of common stock (such shares, the “Unit Shares”) and (ii) a warrant to purchase 1.1 shares of common stock (a “Warrant,” and such shares, the “Warrant Shares”), at a price per Unit of $3.787 to certain investors for gross proceeds of approximately $18 million.

On March 5, 2021, the Company completed an underwritten public offering (the “Public Offering”), in which we issued and sold 7,875,000 shares of our common stock at a price to the public of $8.00 per share. Gross proceeds of the Public Offering were $63 million before deducting underwriting discounts and commissions and other offering expenses payable by the Company. The underwriters retained a 30-day option to purchase up to 1,181,250 shares of common stock at the public offering price, less underwriting discounts and commission.

In March 2019, we entered into an equity distribution agreement (the “Equity Distribution Agreement”) with JMP Securities LLC (“JMP”) to issue and sell shares of our common stock, having an aggregate offering price of up to $12.5 million, from time to time during the term of the Equity Distribution Agreement, through an “at-the-market” equity offering program (the “ ATM Offering”) at our sole discretion, under which JMP acted as our agent. The Company paid JMP a commission of 3.0% of the gross proceeds from each sale of shares pursuant to the Equity Distribution Agreement, reimbursed legal fees and disbursements and provided JMP with customary indemnification and contribution rights. As of December 31, 2020, we had sold approximately $2.3 million of shares of our common stock pursuant to the Equity Distribution Agreement on a gross basis. Effective as of March 2, 2021, the Equity Distribution Agreement and the ATM Offering were terminated.

Future capital requirements will also depend on the extent to which we acquire or invest in additional complementary businesses, products and technologies. We currently have no understandings, commitments or agreements relating to any of these types of transactions. If we are unable to raise additional funds when needed, we may be required to sell or license to others technologies or clinical product candidates or programs that we would prefer to develop and commercialize ourselves. Without additional funding — or, alternatively, a partner willing to collaborate and fund development — we will be unable to continue development of PL1200 Ibuprofen or any other development-stage products in our pipeline.

We are substantially dependent on the success of our lead product candidate, VAZALORE. If we are unable to successfully commercialize VAZALORE or experience significant delays in doing so, our business could be materially harmed.  

Our future success is substantially dependent on our ability to successfully commercialize VAZALORE, which will depend on several factors, including the following:

Serious adverse events, undesirable side effects or other unexpected properties of VAZALORE or any other product candidate may be identified after approval that could delay, prevent or cause the withdrawal of regulatory approval, limit the commercial potential, or result in significant negative consequences following marketing approval.

Serious adverse events or undesirable side effects caused by, or other unexpected properties of, VAZALORE or our other product candidates could cause us, an IRB, or regulatory authorities to interrupt, delay or halt our manufacturing and distribution operations and could result in a more restrictive label, the imposition of distribution or use restrictions or the delay or denial of regulatory approval by the FDA or comparable foreign regulatory authorities. If VAZALORE or any of our other product candidates are associated with serious adverse events or undesirable side effects or have properties that are unexpected, we may need to abandon their development or limit development to certain uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent, less severe or more acceptable from a risk-benefit perspective. Many compounds that initially showed promise in clinical or earlier stage testing have later been found to cause undesirable or unexpected side effects that prevented further development of the compound.

Undesirable side effects or other unexpected adverse events or properties of VAZALORE or any of our other product candidates could arise or become known either during clinical development or, if approved, after the approved product has been marketed. If such an event occurs during development, our trials could be suspended or terminated and the FDA or comparable foreign regulatory authorities could order us to cease further development of, or deny approval of, our other product candidates. If such an event occurs with respect to VAZALORE, a number of potentially significant negative consequences may result, including:

Any of these events could prevent us from achieving or maintaining market acceptance of the affected product candidate, or could substantially increase commercialization costs and expenses, which could delay or prevent us from generating revenue from the sale of our products and harm our business and results of operations.

Even though VAZALORE has already obtained regulatory approval, it may never achieve market acceptance by physicians, patients, and others in the medical community necessary for commercial success and the market opportunity may be smaller than we estimate.

Even if we are able to launch VAZALORE commercially, it may not achieve market acceptance among physicians, patients, hospitals (including pharmacy directors) and third-party payors and, ultimately, may not be commercially successful. Market acceptance of VAZALORE and any potential product candidate for which we receive approval depends on a number of factors, including:

For example, while we believe that the safety profile and certain efficacy data will allow us to differentiate VAZALORE from other aspirin products in the market, we may not be able to make direct comparative claims regarding the safety or efficacy of VAZALORE and other aspirin products in our promotional materials for VAZALORE. Any failure by VAZALORE or any other product candidate that obtains regulatory approval to achieve market acceptance or commercial success would adversely affect our business prospects.

Our ability to market VAZALORE for long-term use may be hampered by lack of trial results demonstrating long-term GI-safety benefits.

While demonstrating a statistically significant reduction in mucosal damage at 42 days when evaluated using the same clinical endpoints used for early studies involving enteric-coated aspirin, VAZALORE 325 mg did not demonstrate a reduction in ulcer risk over the course of a 42-day trial when more contemporary clinical endpoints were used. This lack of demonstrated long-term GI benefits could hamper our ability to market VAZALORE 325 mg for long-term use.

For many new product candidates, we will rely on third parties to conduct our preclinical studies and all of our clinical trials. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may be unable to obtain regulatory approval for or commercialize any of our product candidates.

If we elect to pursue new products, we will rely on medical institutions, clinical investigators, contract laboratories and other third parties, such as contract research organizations, to conduct our preclinical studies and clinical trials on our product candidates in compliance with applicable regulatory requirements. These third parties are not our employees and, except for restrictions imposed by our contracts with such third parties, we have limited ability to control the amount or timing of resources that they devote to our programs. Although we rely on these third parties to conduct our preclinical studies and clinical trials, we remain responsible for ensuring that each of our preclinical studies and clinical trials is conducted in accordance with its investigational plan and protocol and the applicable legal, regulatory, and scientific standards, and our reliance on these third parties does not relieve us of our regulatory responsibilities. The FDA and regulatory authorities in other jurisdictions require us to comply with regulations and standards, commonly referred to as cGCPs for conducting, monitoring, recording and reporting the results of clinical trials, in order to ensure that the data and results are scientifically credible and accurate and that the trial subjects are adequately informed of the potential risks of participating in clinical trials. If we or any of our third-party contractors fail to comply with applicable cGCPs, the clinical data generated in our clinical trials may be deemed unreliable and the FDA or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. In addition, we are required to report certain financial interests of our third-party investigators if these relationships exceed certain financial thresholds and meet other criteria. Our clinical trials must also generally be conducted with products produced under cGMP regulations. Our failure to comply with these regulations may require us to repeat clinical trials, which would delay the regulatory approval process.

Many of the third parties with whom we contract may also have relationships with other commercial entities, some of which may compete with us. If the third parties conducting our preclinical studies or our clinical trials do not perform their contractual duties or obligations or comply with regulatory requirements, we may need to enter into new arrangements with alternative third parties. This could be costly, and our preclinical studies or clinical trials may need to be extended, delayed, terminated or repeated, and we may not be able to obtain regulatory approval in a timely fashion, or at all, for the applicable product candidate, or to commercialize such product candidate being tested in such studies or trials. If any of our relationships with these third parties terminate, we may not be able to enter into arrangements with alternative third-party contractors or to do so on commercially reasonable terms. Though we carefully manage our relationships with our contract research organizations, there can be no assurance that we will not encounter similar challenges or delays in the future or that these delays or challenges will not have a material adverse impact on our business, financial condition and prospects.

Clinical trials may be delayed or prevented for a broad range of reasons, including:

One or more of these difficulties could result in delayed or cancelled trials and have a significant negative impact on our earnings.

We will rely on third-party contract manufacturing organizations to manufacture and supply VAZALORE and other product candidates for us, as well as certain raw materials used in the production thereof. If one of our suppliers or manufacturers fails to perform adequately, we may be required to incur significant delays and costs to find new suppliers or manufacturers.

We currently have limited experience in, and we do not own facilities for, manufacturing our product candidates, including VAZALORE. We rely upon third-party manufacturing organizations to manufacture and supply our product candidates and certain raw materials used in the production thereof. Some of our key components for the production of VAZALORE have a limited number of suppliers.

We will not control the manufacturing process of, and will be completely dependent on, our contract manufacturing partners for compliance with cGMP regulations for manufacture of our drug products. We will be relying on our contract manufacturers to successfully manufacture material that conforms to our specifications and the strict regulatory requirements of the FDA or a comparable foreign regulatory authority. In addition, although we will have no day-to-day control over the ability of our contract manufacturers to maintain adequate quality control, quality assurance and qualified personnel, we are nonetheless responsible for ensuring that our drug products are manufactured in accordance with cGMPs. If the facilities that manufacture our drug products fail to maintain a cGMP compliance status acceptable to the FDA or a comparable foreign regulatory authority, we may need to find alternative manufacturing facilities, which would significantly impact our ability to develop, obtain regulatory approval for or market our product candidates, if approved. The FDA or a comparable foreign regulatory authority could also take enforcement action with regard to the facilities or the drug products.

We have entered into a Manufacturing Services Agreement with Thermo Fisher’s Pharma Services business, to provide the capabilities to bring VAZALORE to market. We do not have commercial supply agreements with all of our raw material suppliers. In the event that we and our suppliers cannot agree to the terms and conditions for them to provide clinical and commercial supply needs, we would not be able to manufacture our product candidates until a qualified alternative supplier is identified, which could also delay the development of, and impair our ability to commercialize, our product candidates.

Our third-party suppliers may not be able to meet our supply needs or timelines and this may negatively affect our business. The failure of third-party manufacturers or suppliers to perform adequately or the termination of our arrangements with any of them may adversely affect our business.

We may be subject to costly product liability claims related to our products and product candidates and, if we are unable to obtain adequate insurance or are required to pay for liabilities resulting from a claim excluded from, or beyond the limits of, our insurance coverage, a material liability claim could adversely affect our financial condition.

We face the risk that the use of our product candidates may result in adverse side effects and as a result may expose us to significant product liability claims. Although we currently have product liability insurance coverage in the amount of $5 million, our insurance may be insufficient to reimburse us for any expenses or losses we may suffer, and we may be required to increase our product liability insurance coverage as we increase the size of our operations. We do not know whether we will be able to continue to obtain product liability coverage and obtain expanded coverage if we require it, on acceptable terms, if at all. We may not have sufficient resources to pay for any liabilities resulting from a claim excluded from, or beyond the limits of, our insurance coverage. To the extent that we are required to provide indemnities in favor of third parties, there is also a risk that these third parties could incur liability and bring a claim under such indemnities. An individual may bring a product liability claim against us alleging that one of our product candidates or products has caused an injury or is found to be unsuitable for consumer use. Any product liability claim brought against us, with or without merit, could result in:

Product liability claims may subject us to the foregoing and other risks, which could have a material adverse effect on our business, results of operations, financial condition and prospects.

We currently have no sales, marketing and distribution organization. If we are unable to establish effective sales, marketing and distribution capabilities or enter into third party arrangements for sales, marketing and distribution, we may not be able to effectively market, sell and distribute our product candidates, if approved.

We are currently in the process of building our sales and marketing staff and distribution processes. If we are unable to develop a sales and marketing and distribution capability on our own or through third parties, we will not be successful in commercializing our future products.  To achieve commercial success for any approved product candidate, we must either develop a sales, marketing and distribution organization or outsource these functions to third parties. If we rely on third parties for marketing and distributing our approved products, any revenue we receive will depend upon the efforts of third parties, which may not be successful and are only partially within our control, and our product revenue may be lower than if we directly marketed or sold our products. We have no historical operations in this area, and if such efforts were necessary, we may not be able to successfully commercialize our future products. If we are not successful in commercializing our future products, either on our own or through third parties, any future product revenue will be materially and adversely affected.

We face substantial competition and our competitors may discover, develop or commercialize products faster or more successfully than us.

The development and commercialization of new drug products is highly competitive. We face competition from major pharmaceutical companies and biotechnology companies worldwide with respect to VAZALORE and other product candidates that we may seek to develop or commercialize in the future. There are a number of pharmaceutical and biotechnology companies that currently market and sell products or are pursuing the development of product candidates that compete directly or indirectly with VAZALORE. Potential competitors also include academic institutions, government agencies and other public and private research organizations. Our competitors may succeed in developing, acquiring or licensing technologies and drug products that are more effective, safer or less costly than VAZALORE or any other product candidates that we are currently developing or that we may develop, which could render our product candidates obsolete and noncompetitive.

Many of our competitors have materially greater name recognition and financial, manufacturing, marketing, research and drug development resources than we do. Additional mergers and acquisitions in the biotechnology and pharmaceutical industries may result in even more resources being concentrated in our competitors. Large pharmaceutical companies in particular have extensive expertise in commercial sales, preclinical and clinical testing and in obtaining regulatory approvals for drugs. In addition, academic institutions, government agencies, and other public and private organizations conducting research may seek patent protection with respect to potentially competitive products or technologies. These organizations may also establish exclusive collaborative or licensing relationships with our competitors.

Finally, the success of any product that is commercialized will depend in large part on our ability to prevent competitors from launching a generic version that would compete with such product. If such competitors are able to establish that our patents are invalid or that the generic version would not infringe upon our product, they may be able to launch a generic product prior to the expected expiration of our relevant patents, and any generic competition could have a material adverse effect on our business, results of operations, financial condition and prospects.

We cannot state with certainty when or whether any of our products under development will be launched, whether we will be able to develop, license, or otherwise acquire compounds or products, or whether any products will be commercially successful. Failure to launch successful new products or new indications for existing products may cause our products to become obsolete, causing our revenues and operating results to suffer.

We expect to compete with a large number of multinational pharmaceutical companies, biotechnology companies, and generic pharmaceutical companies. To successfully expand our product offerings, we must continue to deliver to the market innovative, cost-effective products that meet important medical needs. Our product revenues can be adversely affected by the introduction by competitors of branded products that are perceived as superior by the marketplace, by generic or biosimilar versions of our branded products, and by generic or biosimilar versions of other products in the same therapeutic class as our branded products. Our revenues can also be adversely affected by treatment innovations that eliminate or minimize the need for treatment with drugs.

We may attempt to form collaborations in the future with respect to our products, but we may not be able to do so, which may cause us to alter our development and commercialization plans.

We may form strategic alliances, create joint ventures or collaborations or enter into licensing arrangements with third parties with respect to our programs that we believe will complement or augment our existing business. We may attempt to find strategic partners for the commercialization of VAZALORE in other geographic jurisdictions and we may also attempt to find one or more strategic partners for the development or commercialization of one or more of our other product candidates. We face significant competition in seeking appropriate strategic partners, and the negotiation process to secure appropriate terms is time-consuming and complex. We may not be successful in our efforts to establish such a strategic partnership for any product candidates and programs on terms that are acceptable to us, or at all.

Any delays in identifying suitable collaborators and entering into agreements to develop or commercialize our product candidates could negatively impact the development or commercialization of our product candidates in geographic regions where we do not have development and commercialization infrastructure. Absent a collaboration partner, we would need to undertake development or commercialization activities at our own expense. If we elect to fund and undertake development or commercialization activities on our own, we may need to obtain additional expertise and additional capital, which may not be available to us on acceptable terms or at all. If we are unable to do so, we may not be able to develop our product candidates or bring them to market and our business may be materially and adversely affected.

Even if we are successful in entering into a collaboration with respect to the development or commercialization of one or more product candidates, there is no guarantee that the collaboration will be successful. Collaborations may pose a number of risks, including:

As a result, a collaboration may not result in the successful development or commercialization of our product candidates.

We will need to grow our organization, and we may experience difficulties in managing growth.

As of December 31, 2020, we had 11 employees, of which 8 are full time employees. We will need to expand our managerial, operational, financial and other resources in order to manage our operations, continue our development activities, commercialize VAZALORE or other product candidates and comply with our obligations as a public reporting company. Our management and personnel, systems and facilities currently in place may not be adequate to support this future growth. Our need to effectively execute our business strategy requires that we:

If we are unable to expand our managerial, operational, financial, and other resources to the extent required to manage our development and commercialization activities, our business will be materially adversely affected.

We are highly dependent on the services of our executive management team, and on our ability to attract and retain qualified personnel.  We may not be able to attract or retain qualified management and scientific and clinical personnel in the future due to the intense competition for qualified personnel among biotechnology, pharmaceutical and other businesses. We are highly dependent on the principal members of our management, particularly our Executive Chairman of the Board, Michael J. Valentino, our President and Chief Executive Officer, Natasha Giordano, and our Chief Financial Officer, Rita O’Connor. If we are not able to retain Mr. Valentino, Ms. Giordano, or Ms. O’Connor, or are not able to attract, on acceptable terms, additional qualified personnel necessary for the continued development of our business, we may not be able to sustain our operations or grow. Although we have executed employment agreements with each member of our current executive management team, including Mr. Valentino, Ms. Giordano and Ms. O’Connor, we may not be able to retain their services as expected.

In addition, we have scientific and clinical advisors who assist us in formulating our product development and clinical strategies. These advisors are not our employees and may have commitments to, or consulting or advisory contracts with, other entities that may limit their availability to us, or may have arrangements with other companies to assist in the development of products that may compete with ours.

If we are not able to attract, retain and motivate necessary personnel to accomplish our business objectives, we may experience constraints that will significantly impede the achievement of our development objectives, our ability to raise additional capital and our ability to implement our business strategy.

Our business involves the use of hazardous materials and we and our third-party manufacturers must comply with environmental laws and regulations, which may be expensive and restrict how we do business.

Our third-party manufacturers’ activities and our own activities may involve the controlled storage, use and disposal of hazardous materials, including the components of our pharmaceutical product candidates, test samples and reagents, biological materials and other hazardous compounds. We and our manufacturers are subject to various environmental, health and safety laws and regulations, including federal, state, local and foreign laws and regulations governing the use, generation, manufacture, storage, handling and disposal of these hazardous materials. We currently carry no insurance specifically covering environmental claims relating to the use of hazardous materials, with the exception of workers’ compensation coverage for our employees. Although we believe that our safety procedures for handling and disposing of these materials and waste products comply with the standards prescribed by these laws and regulations, we cannot eliminate the risk of accidental injury or contamination from the use, storage, handling or disposal of hazardous materials. In the event of an accident, state or federal or other applicable authorities may curtail our use of these materials and/or interrupt our business operations. In addition, if an accident or environmental discharge occurs, or if we discover contamination caused by prior operations, including by prior owners and operators of properties we acquire, we could be liable for cleanup obligations, damages and fines. If such unexpected costs are substantial, this could significantly harm our financial condition and results of operations.

We or the third parties upon whom we depend may be adversely affected by natural disasters.

Changes to global climate, extreme weather and natural disasters could affect demand for our products and services, cause disruptions in manufacturing and distribution networks, alter the availability of goods and services within the supply chain, and affect the overall design and integrity of our operations.

Our corporate headquarters is located in Sparta, New Jersey, which in the past has experienced weather-related incidents. Natural disasters could severely disrupt our operations, and have a material adverse effect on our business, operations, financial condition and prospects. If a natural disaster, power outage or other event occurred that prevented us from using all or a significant portion of our headquarters, that damaged critical infrastructure, such as our information technology systems, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible for us to continue our business for a substantial period of time.

If such an event were to affect our supply chain, it could have a material adverse effect on our business.

Our employees, independent contractors, principal investigators, consultants and vendors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements.

We are exposed to the risk that our employees, independent contractors, principal investigators, consultants and vendors may engage in fraudulent or other illegal activity. Misconduct by these parties could include intentional, reckless and/or negligent conduct or disclosure of unauthorized activities to us that violates:

Specifically, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Activities subject to these laws also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and serious harm to our reputation.

It is not always possible to identify and deter misconduct by our employees and other third parties, and the precautions we take to detect and prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in compliance with such laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of civil, criminal and administrative penalties, damages, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could adversely affect our ability to operate our business and our results of operations.

If we are not able to implement the requirements of Section 404 of the Sarbanes-Oxley Act of 2002 in a timely manner or with adequate compliance, we may be subject to sanctions by regulatory authorities.

As a public company, we are required to comply with significant legal, accounting, and other requirements and as such, have incurred significant regulatory compliance-related expenses. The Sarbanes-Oxley Act of 2002 as well as rules implemented by the SEC and NASDAQ, impose various requirements on public companies, including those related to corporate governance practices. Our management and other personnel devote a substantial amount of time to these requirements. Some members of management do not have significant experience in addressing these requirements. Moreover, these rules and regulations have increased our legal and financial compliance costs relative to those of previous years and make some activities more time consuming and costly.

The Sarbanes-Oxley Act requires, among other things, that we maintain effective internal controls for financial reporting and disclosure controls and procedures. In particular, we must perform system and process evaluation and testing of our internal controls over financial reporting to allow management to report on the effectiveness of our internal controls over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act. The Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) provides a framework for companies to assess and improve their internal control systems. Our compliance with these requirements has required that we incur substantial accounting and related expenses and expend significant management efforts. Moreover, if we are not able to comply with the requirements of Section 404 of the Sarbanes-Oxley Act, are unable to assert that our internal controls over financial reporting are effective, or identify deficiencies that are deemed to be material weaknesses, investors could lose confidence in the accuracy and completeness of our financial reports, the market price of our common stock could decline and we could be subject to sanctions or investigations by NASDAQ, the SEC, or other regulatory authorities. Any of these events could have a material adverse effect on our business, financial position, and operating results.

Our ability to utilize the Company’s or Dipexium’s net operating loss and tax credit carryforwards in the future is subject to substantial limitations and may be further limited as a result of the Merger and any new tax law changes.

Under Section 382 of the Internal Revenue Code of 1986, as amended, if a corporation undergoes an “ownership change” (generally defined as a greater than 50 percent change (by value) in its equity ownership over a three-year period), the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes to offset its post-change income may be limited. Further, if the historic business of Dipexium is not treated as being continued by us for the two- year period beginning on the date of the merger (referred to as the “continuity of business requirement”), the pre-Merger net operating loss carryforward deductions become substantially reduced or unavailable for use by the surviving corporation in the transaction. It is expected that the Merger resulted in an “ownership change” of Dipexium. Accordingly, our ability to utilize the Company’s and Dipexium’s net operating loss and tax credit carryforwards may be substantially limited. These limitations, in turn, could result in increased future tax payments for the combined organization, which could have a material adverse effect on the business, financial condition or results of operations of the combined organization.

Our understanding of the safety and efficacy of VAZALORE could change as larger portions of the population begin using VAZALORE.

VAZALORE, like all NSAIDs, poses specific risks, including stomach bleeding and, for aspirin, Reyes syndrome. As the product is used by additional patients, we may discover new risks associated with VAZALORE which may result in changes to the distribution program and additional restrictions on the use of VAZALORE which may decrease demand for the product. Regulatory authorities have been moving towards more active and transparent pharmacovigilance and are making greater amounts of standalone safety information and clinical trial data directly available to the public through websites and other means, e.g., periodic safety update report summaries, risk management plan summaries and various adverse event data. Safety information, without the appropriate context and expertise, may be misinterpreted and lead to misperception or legal action which may potentially cause our product sales or stock price to decline. Further, if serious safety, resistance or drug interaction issues arise with our marketed products, sales of these products could be limited or halted by us or by regulatory authorities and our results of operations would be adversely affected.

Adverse safety events involving our marketed products may have a negative impact on our business.

Discovery of safety issues with our products could create product liability and could cause additional regulatory scrutiny and requirements for additional labeling, withdrawal of products from the market, and the imposition of fines or criminal penalties. Adverse safety events may also damage physician and patient confidence in our products and our reputation. Any of these could result in liabilities, loss of revenue, material write-offs of inventory, material impairments of intangible assets, goodwill and fixed assets, material restructuring charges and other adverse impacts on our results of operations. The reporting of adverse safety events involving our products or products similar to ours and public rumors about such events may increase claims against us and may also cause our product sales or stock price to decline or experience periods of volatility. Restrictions on use or significant safety warnings that may be required to be included in the label of our products — such as the risk of developing an allergic reaction to soy, stomach bleeding or Reyes syndrome, in the label for VAZALORE — may significantly reduce expected revenues for this product and require significant expense and management time.

Unexpected safety or efficacy concerns can arise with respect to marketed products, whether or not scientifically justified, leading to product recalls, withdrawals, or declining sales, as well as product liability, consumer fraud and/or other claims, including potential civil or criminal governmental actions.

Our business will be highly dependent on professional and public reputation and perception, which may change, leading to volatile sales.

Market perceptions of the Company are very important to our business, especially market perceptions of our company and brands and the safety and quality of our products. If we, our partners and suppliers, or our brands suffer from negative publicity, or if any of our products or similar products which other companies distribute are subject to market withdrawal or recall or are proven to be, or are claimed to be, ineffective or harmful to consumers, then this could have a material adverse effect on our business, financial condition, results of operations, cash flows, and/or share price. Also, because we are dependent on market perceptions, negative publicity associated with product quality, patient illness, or other adverse effects resulting from, or perceived to be resulting from, our products, or our partners’ and suppliers’ manufacturing facilities, could have a material adverse effect on our business, financial condition, results of operations, cash flows, or share price.

We must be able to adapt to changed circumstances and quickly update product labels, which could be costly or harm our reputation.

We may be required by regulatory authorities to change the labeling for any pharmaceutical product, including after a product has been marketed for several years. These changes are often the result of additional data from post-marketing studies, head-to-head trials, adverse events reports, studies that identify biomarkers (objective characteristics that can indicate a particular response to a product or therapy) or other studies or post-marketing experience that produce important additional information about a product. New information added to a product’s label can affect its risk-benefit profile, leading to potential recalls, withdrawals, or declining revenue, as well as product liability claims. Sometimes additional information from these studies identifies a portion of the patient population that may be nonresponsive to a medicine or would be at higher risk of adverse reactions and labeling changes based on such studies may limit the patient population. The studies providing such additional information may be sponsored by us, but they could also be sponsored by competitors, insurance companies, government institutions, managed care organizations, scientists, investigators, or other interested parties. While additional safety and efficacy information from such studies can assist us and healthcare providers in identifying the best patient population for each product, it can also negatively impact our revenues due to inventory returns and a more limited patient population going forward. Additionally, certain study results, especially from head-to-head trials, could affect a product’s reimbursement status or priority with certain payors, which could also adversely affect revenues.

If we are unable to obtain and maintain sufficient intellectual property protection for VAZALORE or our future product candidates, or if the scope of the intellectual property protection is not sufficiently broad, our competitors could develop and commercialize products similar or identical to ours, and our ability to successfully commercialize our product candidates may be adversely affected.

We rely upon a combination of patents, trade secret protection and confidentiality agreements to protect the intellectual property related to our technologies. If we do not adequately protect our intellectual property, competitors may be able to use our technologies and erode or negate any competitive advantage we may have, which could harm our business and ability to achieve profitability. In particular, our success depends in large part on our ability to obtain and maintain patent protection in the United States and other countries with respect to our product candidates. However, we may not be able to file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. We may also fail to identify patentable aspects of our research and development before it is too late to obtain patent protection.

Further, the patentability of inventions, and the validity, enforceability and scope of patents in the pharmaceutical field involve complex legal and scientific questions and can be uncertain. As a result, patent applications that we own or license may fail to result in issued patents in the United States or in other foreign countries for many reasons. For example, since patent applications in the United States and most other countries are confidential for a period of time after filing, we cannot be certain that we were the first to file any patent application related to our product candidates. Even if patents have issued, or do successfully issue, from patent applications, third parties may challenge the validity, enforceability or scope thereof, which may result in such patents being narrowed, invalidated or held unenforceable. Furthermore, even if they are unchallenged, our patents and patent applications may not adequately protect our intellectual property or prevent others from designing around our claims. If the breadth or strength of protection provided by the patents and patent applications we hold, license or pursue with respect to our product candidates is threatened, it could threaten our ability to commercialize our product candidates. Further, if we encounter delays in our clinical trials, the period of time during which we could market any of our product candidates under patent protection, if approved, would be reduced. Changes to the patent laws in the United States and other jurisdictions could also diminish the value of our patents and patent applications or narrow the scope of our patent protection.

If we are unable to protect the confidentiality of our trade secrets, the value of our technology could be materially adversely affected and our business would be harmed.

In addition to the protection afforded by patents, we rely on confidential proprietary information — including trade secrets and know-how — to develop and maintain our competitive position. Any disclosure to or misappropriation by third parties of our confidential proprietary information could enable competitors to quickly duplicate or surpass our technological achievements, thus eroding our competitive position in our market. We seek to protect our confidential proprietary information, in part, by confidentiality agreements and invention assignment agreements with our employees and confidentiality agreements with consultants, scientific advisors, contractors and collaborators. These agreements are designed to protect our proprietary information. However, we cannot be certain that such agreements have been entered into with all relevant parties, and we cannot be certain that our trade secrets and other confidential proprietary information will not be disclosed or that competitors will not otherwise gain access to our trade secrets or independently develop substantially equivalent information and techniques. For example, any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. We also seek to preserve the integrity and confidentiality of our confidential proprietary information by maintaining physical security of our premises and physical and electronic security of our information technology systems, but it is possible that these security measures could be breached. If any of our confidential proprietary information were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent such competitor from using that technology or information to compete with us, which could harm our competitive position. If we are unable to prevent material disclosure of the intellectual property related to our technologies to third parties, we will not be able to establish or maintain a competitive advantage in our market, which could materially adversely affect our business, results of operations and financial condition.

If we are sued for infringing intellectual property rights of third parties, such litigation could be costly and time consuming and could prevent or delay us from developing or commercializing our product candidates.

There is a substantial amount of intellectual property litigation in the biotechnology and pharmaceutical industries, and we may become party to, or threatened with, litigation or other adversarial proceedings regarding intellectual property rights with respect to our technology or product candidates, including post-grant or inter-partes proceedings, interference or derivation proceedings before the USPTO. Third parties may assert infringement claims against us based on existing or future intellectual property rights. The outcome of intellectual property litigation is subject to uncertainties that cannot be adequately quantified in advance. The pharmaceutical and biotechnology industries have produced a significant number of patents, and it may not always be clear to industry participants, including us, which patents cover various types of products or methods of use. The coverage of patents is subject to interpretation by the courts, and the interpretation is not always uniform. If we are sued for patent infringement, we would need to demonstrate that our product candidates, products or methods either do not infringe the patent claims of the relevant patent or that the patent claims are invalid, and we may not be able to do this. Proving that a patent is invalid is difficult. For example, in the United States, proving invalidity requires a showing of clear and convincing evidence to overcome the presumption of validity enjoyed by issued patents. Even if we are successful in these proceedings, we may incur substantial costs and the time and attention of our management and scientific personnel could be diverted in pursuing these proceedings, which could have a material adverse effect on us.

If we are found to infringe a third party’s intellectual property rights, we could be forced, including by court order, to cease developing, manufacturing or commercializing the infringing product candidate or product. Alternatively, we may be required to obtain a license from such third party in order to use the infringing technology and continue developing, manufacturing or marketing the infringing product candidate. However, we may not be able to obtain any required license on commercially reasonable terms or at all. Even if we were able to obtain a license, it could be nonexclusive, thereby giving our competitors access to the same technologies licensed to us. In addition, we could be found liable for monetary damages, including treble damages and attorneys’ fees, if we are found to have willfully infringed a patent. A finding of infringement could prevent us from commercializing our product candidates or force us to cease some of our business operations, which could materially harm our business. We may also elect to enter into license agreements in order to settle patent infringement claims or to resolve disputes prior to litigation, and any such license agreements may require us to pay royalties and other fees that could be significant. Claims that we have misappropriated the confidential information or trade secrets of third parties could have a similar negative impact on our business.

We may be involved in lawsuits to protect or enforce our intellectual property rights which could be expensive, time consuming and unsuccessful.

Competitors may infringe or otherwise violate our patents, the patents of our licensors, or our other intellectual property rights. To counter infringement or unauthorized use, we may be required to file infringement claims, which can be expensive and time-consuming. Any claims that we assert against perceived infringers could also provoke these parties to assert counterclaims against us alleging that we infringe their intellectual property rights. In addition, in an infringement proceeding, a court may decide that a patent of ours is not valid or is unenforceable, in whole or in part, or may refuse to stop the other party in such infringement proceeding from using the technology at issue on the grounds that our patents do not cover the technology in question. An adverse result in any litigation or defense proceedings could put one or more of our patents at risk of being invalidated, held unenforceable or interpreted narrowly, and could put any of our patent applications at risk of not yielding an issued patent.

Post-grant or inter-parte proceedings, interference or derivation proceedings provoked by third parties or brought by the USPTO or any foreign patent authority may be necessary to determine the priority of inventions or other matters of inventorship with respect to our patents or patent applications. We may also become involved in other proceedings, such as reexamination or opposition proceedings, before the USPTO or its foreign counterparts relating to our intellectual property or the intellectual property rights of others. An unfavorable outcome in any such proceedings could require us to cease using the related technology or to attempt to license rights to it from the prevailing party, or could cause us to lose valuable intellectual property rights. Our business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms, if any license is offered at all. Litigation or other proceedings may fail and, even if successful, may result in substantial costs and distract our management and other employees. We may also become involved in disputes with others regarding the ownership of intellectual property rights. For example, we jointly develop intellectual property with certain parties, and disagreements may therefore arise as to the ownership of the intellectual property developed pursuant to these relationships. If we are unable to resolve these disputes, we could lose valuable intellectual property rights.

We may not be able to prevent misappropriation of our trade secrets or confidential information, particularly in countries where the laws may not protect those rights as fully as in the United States. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the price of our common stock. Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses, and could distract our technical and/or management personnel from their normal responsibilities. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available for development activities or any future sales, marketing or distribution activities. Uncertainties resulting from the initiation and continuation of intellectual property litigation or other proceedings could negatively affect our ability to compete in the marketplace.

We may not be able to protect our intellectual property rights throughout the world.

Filing, prosecuting and defending patents on all of our product candidates throughout the world would be prohibitively expensive. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and, further, may export otherwise infringing products to territories where we have patent protection but where enforcement is not as strong, or where standards are different than they are in the United States. These products may compete with our products in jurisdictions where we do not have any issued patents and our patent claims or other intellectual property rights may not be effective or sufficient to prevent them from so competing. Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents and other intellectual property protection, particularly those relating to biopharmaceuticals, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights generally. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial cost and divert our efforts and attention from other aspects of our business.

If we breach any of the agreements under which we license the use, development and commercialization rights to our product candidates from third parties, we could lose license rights that are important to our business.

In addition to our own patents, an important patent family covering VAZALORE is owned by UT. Our development and commercialization of VAZALORE is subject to our UT License Agreement. Under our UT License Agreement, we are subject to various obligations, including diligence obligations with respect to development and commercialization activities, payment obligations for achievement of certain milestones and royalties on product sales, as well as other material obligations. If we fail to comply with any of these obligations or otherwise breach UT License Agreement, UT may have the right to terminate the applicable license in whole or in part. Specifically, Section 4.6 of our UT License Agreement provides that “Reasonable commercial diligence shall require that [the Company] . . . . [o]n or before September 8, 2013, Sell or offer for Sale a Licensed Product.” While we believe that we have exercised reasonable commercial diligence to actively attempt such commercialization, we have not yet successfully commercialized a licensed product. As such, UT may have the option to terminate the UT License Agreement, or to limit the exclusivity of the license in certain territories.

The loss of our license agreement with UT could materially adversely affect our ability to proceed with the development or potential commercialization of VAZALORE as currently planned, and could materially adversely affect our ability to proceed with any development or potential commercialization of PL1200 Ibuprofen and other NSAID programs. The risks described elsewhere pertaining to our patents and other intellectual property rights also apply to the intellectual property rights that we license, and any failure by us or our licensors to obtain, maintain and enforce these rights could have a material adverse effect on our business. In some cases, we do not have control over the prosecution, maintenance or enforcement of the patents that we license, and may not have sufficient ability to consult and input into the patent prosecution and maintenance process with respect to such patents, and our licensors may fail to take the steps that we believe are necessary or desirable in order to obtain, maintain and enforce the licensed patents.

Limitations on intellectual property rights may result in other threats to our competitive advantage.

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations, and may not adequately protect our business or permit us to maintain our competitive advantage. The following examples are illustrative:

We may be subject to claims that our employees or consultants have wrongfully used or disclosed alleged trade secrets of former or other employers.

Some of our employees, consultants, advisors, and members of our Board of Directors, including our senior management, have been employed or retained by other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Although we try to ensure that our employees and consultants do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or these individuals have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such individuals’ former or other employer. We are not aware of any material threatened or pending claims related to these matters, but in the future litigation may be necessary to defend against such claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management.

The regulatory approval process is expensive, time consuming and uncertain and may prevent us from obtaining, or cause delays in obtaining, approvals for the commercialization of future product candidates, which will materially impair our ability to generate revenue.

The design, development, research, testing, manufacturing, labeling, storage, recordkeeping, approval, selling, import, export, advertising, promotion, and distribution of drug products are subject to extensive and evolving regulation by federal, state and local governmental authorities in the United States, principally by the FDA, and foreign regulatory authorities, with regulations differing from country to country. Failure to obtain marketing approval for a product candidate will prevent us from commercializing the product candidate.

We have not obtained marketing approval for any product candidate other than VAZALORE anywhere in the world. An NDA must include extensive preclinical and clinical data and supporting information to establish to the FDA’s satisfaction the product candidate’s safety and efficacy for each desired indication. The NDA must also include significant information regarding the chemistry, manufacturing and controls for the product candidate. Obtaining regulatory approval of an NDA can be a lengthy, expensive and uncertain process. In addition, failure to comply with FDA and other applicable U.S. and foreign regulatory requirements may subject us to administrative or judicially imposed sanctions, including:

These actions could result in, among other things, substantial modifications to our business practices and operations, refunds of our products, the inability to obtain future approvals or marketing authorizations, and withdrawals or suspensions of current products from the market. Any of these events could disrupt our business and have a material adverse effect on our revenues, profitability and financial condition.

Prior to receiving approval to commercialize any future product candidates in the United States or abroad, we and any applicable collaboration partners must demonstrate with substantial evidence from well-controlled clinical trials, and to the satisfaction of the FDA and other regulatory authorities abroad, that such product candidates are safe and effective for their intended uses. Preclinical testing and clinical trials are long, expensive and uncertain processes. We may spend several years completing our testing for any particular product candidate, and failure can occur at any stage. Negative or inconclusive results or adverse medical events during a clinical trial could also cause the FDA or us to terminate a clinical trial or require that we repeat it or conduct additional clinical trials. Additionally, data obtained from preclinical studies and clinical trials can be interpreted in different ways and the FDA or other regulatory authorities may interpret the results of our studies and trials less favorably than we do. Even if we believe the preclinical or clinical data for a product candidate is promising, such data may not be sufficient to support approval by the FDA and other regulatory authorities. Administering any product candidates to humans may produce undesirable side effects, which could interrupt, delay or halt clinical trials of such product candidates and result in the FDA or other regulatory authorities denying approval of such product candidates for any or all targeted indications. The FDA or other regulatory authorities may determine that any product candidate that we develop is not effective, or are only moderately effective, or have undesirable or unintended side effects, toxicities, safety profile or other characteristics that preclude marketing approval or prevent or limit commercial use. In addition, any marketing approval we ultimately obtain may be limited or subject to restrictions or post-approval commitments that render the approved product not commercially viable.

We are subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense and subject us to restrictions, withdrawal from the market, or penalties if we fail to comply with applicable regulatory requirements or if we experience unanticipated problems with our product candidates, when and if approved.

An approved product and its manufacturer are subject to continual review by the FDA and, as applicable, non-U.S. regulatory authorities. Any regulatory approval that we receive for our product candidates may be subject to limitations on the indicated uses for which the product may be marketed or contain requirements for potentially costly post-marketing follow-up studies or surveillance to monitor the safety and efficacy of the product. In addition, if the FDA or non-U.S. regulatory authorities approve any of our product candidates, we will be subject to extensive and ongoing regulatory requirements by the FDA and other regulatory authorities with regard to labeling, packaging, adverse event reporting, storage, distribution, advertising, promotion, recordkeeping and submission of safety and other post-market information. Manufacturers of our products and manufacturers’ facilities are required to comply with cGMP regulations, which include requirements related to quality control and quality assurance as well as the corresponding maintenance of records and documentation. Further, regulatory authorities must approve these manufacturing facilities before they can be used to manufacture our products, and these facilities are subject to continual review and periodic inspections by the FDA and other regulatory authorities for compliance with cGMP regulations. Accordingly, we and others with whom we work must continue to expend time, money and effort in all areas of regulatory compliance, including manufacturing, production and quality control.

We, and our direct and indirect suppliers, remain subject to the periodic inspection of our plants and facilities, review of production processes, and testing of our products to confirm that we are in compliance with all applicable regulations. For example, the FDA conducts ongoing inspections to determine whether our record keeping, production processes and controls, personnel and quality control are in compliance with the cGMP regulations, and other FDA regulations. Adverse findings during regulatory inspections may result in the implementation of REMS programs, completion of government mandated post-marketing clinical studies, and government enforcement action relating to labeling, advertising, marketing and promotion, as well as regulations governing manufacturing controls noted above. The FDA has increased its enforcement activities related to the advertising and promotion of pharmaceutical, biological and medical device products. We will also be required to report certain adverse reactions and production problems, if any, to the FDA and to comply with requirements concerning advertising and promotion for our products. If we, any future collaboration partner or a regulatory authority discovers previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or problems with the facility where the product is manufactured, a regulatory authority may impose restrictions on that product, the collaboration partner, the manufacturer or us, including requiring withdrawal of the product from the market or suspension of manufacturing.

The FDA closely regulates the post-approval marketing and promotion of drugs to ensure drugs are marketed only for the approved indications and in accordance with the provisions of the approved labeling and regulatory requirements. The FDA also imposes stringent restrictions on manufacturers’ communications regarding off-label use and if we do not restrict the promotion of our products only to their approved indications, we may be subject to enforcement action for off-label promotion. If we, our product candidates or the manufacturing facilities for our product candidates fail to comply with regulatory requirements of the FDA and/or other non-U.S. regulatory authorities, we could be subject to administrative or judicially imposed sanctions, including:

Widely publicized events concerning the safety risk of certain drug products have resulted in the withdrawal of drug products, revisions to drug labeling that further limit use of the drug products and the imposition by the FDA of REMS to ensure that the benefits of the drug outweigh its risks. In addition, because of the serious public health risks of high profile adverse safety events with certain products, the FDA may require, as a condition of approval, costly REMS programs.

The regulatory requirements and policies may change and additional government regulations may be enacted with which we may also be required to comply. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or in other countries. If we or any future collaboration partner are not able to maintain regulatory compliance, we or such collaboration partner, as applicable, will not be permitted to market our future products and our business will suffer.

Failure to obtain regulatory approvals in foreign jurisdictions will prevent us from marketing our products internationally.

We may seek a distribution and marketing collaborator for VAZALORE or other product candidates commercialized outside of the United States. In order to market our product candidates in the European Economic Area (which comprises the 28 member states of the European Union, plus Norway, Iceland and Liechtenstein), and many other foreign jurisdictions, we or our collaboration partners must obtain separate regulatory approvals. We have had limited interactions with foreign regulatory authorities, and approval procedures vary among countries and can involve additional clinical testing. In addition, the time required to obtain approval from foreign regulatory authorities may differ from that required to obtain FDA approval. Clinical trials conducted in one country may not be accepted by regulatory authorities in other countries. Approval by the FDA does not ensure approval by regulatory authorities in other countries, and approval by one or more foreign regulatory authorities does not ensure approval by regulatory authorities in other foreign countries or by the FDA. However, a failure or delay in obtaining regulatory approval in one country may have a negative effect on our ability to obtain approval in other countries. The foreign regulatory approval process generally includes all of the risks associated with obtaining FDA approval. In addition, in many countries outside the United States, it is required that the product be approved for reimbursement before the product can be approved for sale in that country. We may or may not obtain foreign regulatory approvals on a timely basis, if at all. We may not be able to file for regulatory approvals and even if we file, we may not receive necessary approvals to commercialize our product candidates in any market.

Healthcare reform measures could hinder or prevent our product candidates’ commercial success.

In the United States, there have been, and we expect there will continue to be, a number of legislative and regulatory changes to the healthcare system that could affect our future revenue and profitability and the future revenue and profitability of our potential customers. Federal and state lawmakers regularly propose and, at times, enact legislation that results in significant changes to the healthcare system, some of which is intended to contain or reduce the costs of medical products and services. The ACA contained a number of provisions, including those governing enrollment in federal healthcare programs, reimbursement changes and fraud and abuse measures that have impacted and will continue to impact existing government healthcare programs and will result in the development of new programs.

We currently benefit from regulations that mandate full reimbursement without cost sharing for aspirin when prescribed by a health care provider. Changes to these regulations could significantly reduce reimbursement rates in a manner that negatively affects our sales.

As a result of regulations enacted as part of the ACA, we expect that VAZALORE will qualify for coverage when prescribed by physicians for the prevention of cardiovascular disease in patients with certain age-associated risks, requiring no out-of-pocket payments. While this will initially have the potential to expand the demand for VAZALORE, changes to these regulations could have a significant adverse effect on reimbursement rates and, indirectly, on sales of VAZALORE.

We are subject to healthcare laws, regulation and enforcement and our failure to comply with those laws could adversely affect our business, operations and financial condition.

Even though we do not and will not control referrals of healthcare services or bill directly to Medicare, Medicaid or other third-party payors, certain federal and state healthcare laws and regulations pertaining to fraud and abuse and patients’ rights are and will be applicable to our business. We could be subject to healthcare fraud and abuse and patient privacy regulation by both the federal government and the states in which we conduct our business. The regulations that may affect our ability to operate include, without limitation:

In addition, recent healthcare reform legislation has strengthened these laws. For example, the ACA, among other things, amended the intent requirement of the Federal Anti-Kickback Statute and criminal healthcare fraud statutes. A person or entity no longer needs to have actual knowledge of the statute or specific intent to violate it. In addition, the ACA provides that the government may assert that a claim including items or services resulting from a violation of the Federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act.

These laws and regulations are broad in scope and they are subject to change and evolving interpretations, which could require us to incur substantial costs associated with compliance or to alter one or more of our sales or marketing practices. In addition, any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. If our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including civil and criminal penalties, damages, fines, the exclusion from participation in federal and state healthcare programs, imprisonment, or the curtailment or restructuring of our operations, any of which could adversely affect our ability to operate our business and our financial results.

Failure to comply with domestic and international privacy and security laws can result in the imposition of significant civil and criminal penalties. The costs of compliance with these laws, including protecting electronically stored information from cyberattacks, and potential liability associated with failure to do so could adversely affect our business, financial condition and results of operations. We are subject to various domestic and international privacy and security regulations, including but not limited to HIPAA. HIPAA mandates, among other things, the adoption of uniform standards for the electronic exchange of information in common healthcare transactions, as well as standards relating to the privacy and security of individually identifiable health information, which require the adoption of administrative, physical and technical safeguards to protect such information. In addition, many states have enacted comparable laws addressing the privacy and security of health information, some of which are more stringent than HIPAA.

Our international operations will be subject to the Foreign Corrupt Practices Act.

As we pursue international licensing, sales and co-promotion arrangements outside the United States, we will be heavily regulated and expect to have significant interaction with foreign officials. Additionally, in many countries outside the United States, the health care providers who prescribe human pharmaceuticals are employed by the government and the purchasers of human pharmaceuticals are government entities; therefore, our interactions with these prescribers and purchasers would be subject to regulation under the FCPA, which prohibits any U.S. individual or business from paying, offering or authorizing payment or offering of anything of value, directly or indirectly, to any foreign official, political party or candidate for the purpose of influencing any act or decision of the foreign entity in order to assist the individual or business in obtaining or retaining business.

Compliance with these regulations may be costly, and may limit our ability to expand into certain markets. Further, we may inadvertently be found to be in violation of these and other regulations, which could result in material sanctions and penalties.

The market price for the shares of our common stock may fluctuate significantly in response to a number of factors including:

In addition, the stock markets in general, and the markets for pharmaceutical stocks in particular, have experienced extreme volatility that has often been unrelated to the operating performance of the issuer. These broad market fluctuations may adversely affect the trading price or liquidity of our common stock. In the past, when the market price of a stock has been volatile, holders of that stock have sometimes instituted securities class action litigation against the issuer. If any of our stockholders were to bring such a lawsuit against us, we could incur substantial costs defending the lawsuit and the attention of our management would be diverted from the operation of our business.

Our principal stockholders and management own a significant percentage of our stock and will be able to exert significant control over matters subject to stockholder approval.

As of December 31, 2020, our officers and directors, together with holders of 5% or more of our outstanding common stock and their respective affiliates, beneficially owned approximately 37.1% of our common stock. Accordingly, these stockholders have significant influence over the outcome of corporate actions requiring stockholder approval, including the election of directors, any merger, consolidation or sale of all or substantially all of our assets or any other significant corporate transaction. The interests of these stockholders may not be the same as or may even conflict with your interests. For example, these large stockholders could delay or prevent a change of control of our company, even if such a change of control would benefit our other stockholders, which could deprive our stockholders of an opportunity to receive a premium for their common stock as part of a sale of our company or our assets and might affect the prevailing market price of our common stock. The significant concentration of stock ownership may adversely affect the trading price of our common stock due to investors’ perception that conflicts of interest may exist or arise.

We currently have Series A Preferred Stock and Series B Preferred Stock outstanding and our certificate of incorporation authorizes our Board to create new series of preferred stock without further approval by our stockholders, which could adversely affect the rights of the holders of our common stock.

Our Board has the authority to fix and determine the relative rights and preferences of preferred stock. Our Board also has the authority to issue preferred stock without further stockholder approval. We currently have 15,000 shares of Series A Preferred Stock and 8,000 shares of Series B Preferred Stock outstanding, which is convertible at the holder’s option at any time into shares of common stock with an initial conversion price of $2.60 and $3.10 per share, respectively, subject to certain adjustments. Each of the Series A Preferred Stock and Series B Preferred Stock Certificate of Designations provide for the payment of cash dividends on the Series A Preferred Stock and Series B Preferred Stock at a rate of 8.00% per annum, provided that we may pay dividends in-kind through the issuance of additional shares to holders of the Series A Preferred Stock and Series B Preferred Stock. Our Series A Preferred Stock and Series B Preferred Stock gives its holders the preferred right to our assets upon liquidation and the right to receive dividend payments before dividends are distributed to the holders of common stock, among other things. In addition, our Board could authorize the issuance of additional series of preferred stock with such rights preferential to the rights of our common stock, including the issuance of a series of preferred stock that has greater voting power than our common stock or that is convertible into our common stock, which could decrease the relative voting power of our common stock or result in dilution to our existing stockholders.

Future sales of our common stock or securities convertible or exchangeable for our common stock may depress our stock price.

If our existing stockholders or holders of our options or warrants sell, or indicate an intention to sell, substantial amounts of our common stock in the public market, the trading price of our common stock could decline. The perception in the market that these sales may occur could also cause the trading price of our common stock to decline.

We may be at risk of securities class action litigation. This risk is especially relevant for us due to our dependence on positive clinical trial outcomes and regulatory approvals of each of our product candidates. In the past, pharmaceutical companies have experienced significant stock price volatility, particularly when associated with binary events such as clinical trials and product approvals. If we face such litigation, it could result in substantial costs and a diversion of management’s attention and resources, which could harm our business and result in a decline in the market price of our common stock.

Raising additional capital may cause dilution to our existing stockholders or involve the issuance of securities with rights, preferences and privileges senior to those of holders of our common stock.

To raise capital, we may from time to time issue additional shares of common stock at a discount from the then-current trading price of our common stock. As a result, our common stockholders would experience immediate dilution upon the purchase of any shares of our common stock sold at such discount. In addition, as opportunities present themselves, we may enter into financing or similar arrangements in the future, including the issuance of debt securities, preferred stock or common stock. Whether or not we issue additional shares of common stock at a discount, any issuance of common stock will, and any issuance of other equity securities or of options, warrants or other rights to purchase common stock may, result in additional dilution of the percentage ownership of our stockholders and could cause our stock price to decline. New investors could also gain rights, preferences and privileges senior to those of holders of our common stock, which could cause the price of our common stock to decline.

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us more difficult and may prevent attempts by our stockholders to replace or remove management.

Provisions in our certificate of incorporation and bylaws may delay or prevent an acquisition or a change in management. In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which prohibits stockholders owning in excess of 15% of the outstanding combined company voting stock from merging or combining with the combined company. Although we believe these provisions collectively will provide for an opportunity to receive higher bids by requiring potential acquirors to negotiate with our board of directors, they would apply even if the offer may be considered beneficial by some stockholders. In addition, these provisions may frustrate or prevent any attempts by our stockholders to replace or remove then current management by making it more difficult for stockholders to replace members of the board of directors, which is responsible for appointing the members of management.

Provisions of our charter documents limit the liability of our officers and directors, which could limit the ability of stockholders (and outside parties) to bring claims against such officers and directors.

Our certificate of incorporation contains provisions that limit the liability of our current and former directors for monetary damages to the fullest extent permitted by Delaware law. Delaware law provides that directors of a corporation will not be personally liable for monetary damages for any breach of fiduciary duties as directors, except liability for:

Such limitation of liability does not apply to liabilities arising under federal securities laws and does not affect the availability of equitable remedies, such as injunctive relief or rescission.

Our certificate of incorporation and our bylaws provide that we are required to indemnify our directors to the fullest extent permitted by Delaware law. Our bylaws also provide that, upon satisfaction of certain conditions, we shall advance expenses incurred by a director in advance of the final disposition of any action or proceeding, and permit us to secure insurance on behalf of any officer, director, employee or other agent for any liability arising out of his or her actions in that capacity regardless of whether we would otherwise be permitted to indemnify him or her under the provisions of Delaware law. Our certificate of incorporation and bylaws provide our board of directors with discretion to indemnify our officers and employees when determined appropriate by the board. We have entered and expect to continue to enter into agreements to indemnify our directors and executive officers. With certain exceptions, these agreements provide for indemnification for related expenses including, among other things, attorneys’ fees, judgments, fines and settlement amounts incurred by any of these individuals in any action or proceeding. We believe that these bylaw provisions and indemnification agreements are necessary to attract and retain qualified persons as directors and officers. We also maintain customary directors’ and officers’ liability insurance.

The limitation of liability and indemnification provisions in our certificate of incorporation and bylaws may discourage stockholders from bringing a lawsuit against our directors for breach of their fiduciary duty. They may also reduce the likelihood of derivative litigation against our directors and officers, even though an action, if successful, might benefit us and other stockholders. Further, a stockholder’s investment may be adversely affected to the extent that we pay the costs of settlement and damage awards against directors and officers as required by these indemnification provisions. At present, there is no pending litigation or proceeding involving any of our directors, officers or employees for which indemnification is sought, and we are not aware of any threatened litigation that may result in claims for indemnification.

We do not anticipate paying any cash dividends on our capital stock in the foreseeable future; therefore capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future.

We have never declared or paid cash dividends on our common stock. We do not anticipate paying any cash dividends on our common stock in the foreseeable future. We currently intend to retain all available funds and any future earnings to fund the development and growth of our business. In addition, no dividends will be declared or paid or set apart for payment on our common stock unless all accumulated accrued and unpaid dividends in respect of our Series A Preferred Stock and Series B Preferred Stock have been paid or declared and set apart for payment to the holders of Series A Preferred Stock and Series B Preferred Stock.

If securities or industry analysts do not publish research, or publish inaccurate or unfavorable research, about our business, our stock price and trading volume could decline.

The trading market for our common stock will depend, in part, on the research and reports that securities or industry analysts publish about us or our business. Securities and industry analysts may never, publish research on us. If no securities or industry analysts commence coverage, the trading price for our stock would likely be negatively impacted. In the event one or more of the security or industry analysts who cover us downgrade our stock or publish inaccurate or unfavorable research about our business, our stock price would likely decline. In addition, if our operating results fail to meet the forecast of analysts, our stock price would likely decline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, demand for our stock could decrease, which might cause our stock price and trading volume to decline.

The novel coronavirus ("COVID-19") global pandemic could adversely impact our business, including our supply chain.

As a result of the outbreak of novel COVID-19, we may experience disruptions that could impact our supply chain. For example, COVID-19 has resulted in increased travel restrictions and the shutdown or delay of business activities in various regions. To the extent our suppliers and contract manufacturer are unable to comply with their obligations under our agreements with them, our ability to continue advancing the manufacturing of VAZALORE may become impaired. COVID-19 continues to rapidly evolve. The extent to which COVID-19 may impact our business will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the duration of the pandemic, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the pandemic.

Our principal facility consists of office space in Sparta, New Jersey under two operating leases. In Sparta, we occupy approximately 2,463 and 2,232 square feet of office space, with rent of $5,542 and an average of $4,408 per month, respectively, under leases that expire September 30, 2021 and July 1, 2024, respectively. In addition, we lease 5,006 square feet of office space in New York, New York from the former Dipexium headquarters with rent of $19,720 per month under a lease that expires July 31, 2021. We currently sublease the New York facility, which generates income of $17,970 per month.

We are parties to legal proceedings that we believe to be ordinary, routine litigation incidental to the business of present or former operations. It is management’s opinion, based on the advice of counsel, that the ultimate resolution of such litigation will not have a material adverse effect on our financial condition, results of operations or cash flows.

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES.

Our common stock trades on the NASDAQ Capital Market under the symbol “PLXP.”

As of March 9, 2021, there were approximately 81 holders of record of our common stock, which does not include stockholders that beneficially own shares held in a “nominee” or in “street” name.

We have never paid cash dividends on our common stock and do not anticipate paying cash dividends in the foreseeable future. The Certificates of Designation for our Series A Preferred Stock and Series B Preferred Stock prohibit the payment of dividends at any time that we are not current in the payment of dividends with respect to the Series A Preferred Stock or Series B Preferred Stock.

The following table provides information as of December 31, 2020, with respect to the shares of our common stock that may be issued under our existing equity compensation plans.

Recent Sales of Unregistered Securities and Use of Proceeds from Registered Securities

In December 2018, we entered into the Purchase Agreement with Park West Investors Master Fund, Limited, a Cayman Islands exempted company, and Park West Partners International, Limited, a Cayman Islands exempted company, for the Series A Private Placement of $15.0 million of our Series A Preferred Stock, at a price of $1,000 per share, in reliance upon the exemption from securities registration afforded by the provisions of Regulation D under the Securities Act of 1933. Following the attainment of stockholder approval of the transaction at a special meeting of stockholders on February 19, 2019, the Series A Private Placement closed on February 20, 2019. Pursuant to the Certificate of Designations of the Series A Preferred Stock, each share of Series A Preferred Stock can be converted, at the holder’s option at any time, into shares of the Company’s common stock at a conversion rate equal to the quotient of (i) the $1,000 stated value divided by (ii) the initial conversion price of $2.60, subject to specified adjustments for stock splits, cash or stock dividends, recapitalizations, combinations, subdivisions or other similar events as set forth in the Certificate of Designations. In connection with the Purchase Agreement, we also issued warrants to purchase an aggregate of 500,000 shares of our common stock to the investors, exercisable at a price of $3.50 per share, provided that the Series A Private Placement did not close by April 15, 2019. Following the closing of the Series A Private Placement, the investors surrendered the warrants to the Company for cancellation. In March 2019, the Company filed a registration statement on Form S-3 to register for resale the shares issuable upon conversion of the Series A Preferred Stock.

In March 2020, the Company entered into a purchase agreement with certain accredited investors for the private placement of $8.0 million of Series B Preferred Stock pending stockholders' approval, which approval was subsequently obtained on May 15, 2020. Accordingly, the Company completed the Series B Private Placement on May 15, 2020, raising $8.0 million through the issuance of 8,000 shares of Series B Preferred Stock in reliance upon the exemption from securities registration afforded by the provisions of Regulation D under the Securities Act of 1933. The Series B Preferred Stock was issued at $1,000 per share and is convertible into common shares at a conversion price of $3.10 per share, subject to certain adjustments. Holders of the Series B Preferred Stock are entitled to an initial dividend rate of 8.0% per annum, which will stop accruing on the date of the FDA’s approval of the supplemental NDA of VAZALORE 325 mg and VAZALORE 81mg. The dividends are compounded quarterly and payable in cash or shares of Series B Preferred Stock at the Company’s option. The Series B Preferred Stock carries a liquidation preference equal to its stated value of $1,000 plus accrued and unpaid dividends. In June 2020, the Company filed a registration statement on Form S-3 to register for resale the shares issuable upon conversion of the Series B Preferred Stock.

On November 16, 2020, the Company entered into a securities purchase agreement with certain institutional and accredited investors, pursuant to which the Company agreed to issue and sell to the Investors an aggregate of 4,755,373 Units, with each Unit being comprised of (i) one share of the Company’s common stock, and (ii) a warrant to purchase 1.1 shares of Common Stock , at a price per Unit of $3.787, for gross proceeds of approximately $18 million in reliance upon the exemption from securities registration afforded by the provisions of Regulation D under the Securities Act of 1933. Raymond James & Associates, Inc. (the “Placement Agent”) acted as placement agent in connection with the private placement. Pursuant to the terms of a Placement Agency Agreement, dated November 16, 2020, between the Company and the Placement Agent (the “Placement Agency Agreement”), upon the closing of the private placement, the Company paid the Placement Agent an aggregate cash fee equal to 6.0% of the aggregate gross proceeds from the Private Placement plus the reimbursement of certain expenses with respect to the private placement. In December 2020, the Company filed a registration statement on Form S-3 to register for resale the shares issuable upon the exercise of the Warrants.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS.

Statements in this Form 10-K that are not strictly historical are forward-looking statements and include statements about products in development, results and analyses of pre-clinical studies, clinical trials and studies, research and development expenses, cash expenditures, and alliances and partnerships, among other matters. You can identify these forward-looking statements because they involve our expectations, intentions, beliefs, plans, projections, anticipations, or other characterizations of future events or circumstances. These forward-looking statements are not guarantees of future performance and are subject to risks and uncertainties that may cause actual results to differ materially from those in the forward-looking statements as a result of any number of factors. These factors include, but are not limited to, risks relating to our ability to conduct and obtain successful results from ongoing clinical trials, commercialize our technology, obtain regulatory approval for our product candidates, contract with third parties to adequately test and manufacture our proposed therapeutic products, protect our intellectual property rights and obtain additional financing to continue our development efforts. Some of these factors are more fully discussed in Part I, Item 1A, “Risk Factors” and in our consolidated financial statements and related notes, included elsewhere herein. We do not undertake to update any of these forward-looking statements or to announce the results of any revisions to these forward-looking statements except as required by law. For further information regarding forward-looking statements, please refer to the “Information Regarding Forward-Looking Statements” at the beginning of Part I of this Form 10-K.

Our Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) is provided in addition to the accompanying financial statements and notes to assist readers in understanding our results of operations, financial condition and cash flows.

We are a specialty pharmaceutical company focused on our clinically-validated and patent-protected PLxGuard drug delivery platform to provide more effective and safer products. Our PLxGuard drug delivery platform works by targeting the release of active pharmaceutical ingredients to various portions of the gastrointestinal tract. We believe this has the potential to improve the absorption of many drugs currently on the market or in development, and to reduce the risk of stomach erosions and ulcers associated with certain drugs.

VAZALORE, available in two doses, 325 mg and 81 mg, is an FDA-approved liquid-filled aspirin capsule that provides patients with vascular disease and diabetic patients who are candidates for aspirin therapy based on physician recommendation, with fast, reliable and predictable platelet inhibition. It also reduces the risk of stomach erosions and ulcers, as compared to immediate release aspirin, common in an acute setting.

Our commercialization strategy will target the over-the-counter (“OTC’) market, taking advantage of the existing distribution channels for aspirin. We intend to market VAZALORE to the healthcare professional and the consumer through several sales and marketing channels. Our product pipeline also includes other oral nonsteroidal anti-inflammatory drugs using the PLxGuard drug delivery system that may be developed, including PL1200 Ibuprofen 200 mg and PL1200 Ibuprofen 400 mg, for pain and inflammation in Phase 1 clinical stage.

Our consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. Note 3 of the Notes to Consolidated Financial Statements included elsewhere herein describes the significant accounting policies used in the preparation of the financial statements. Certain of these significant accounting policies are considered to be critical accounting policies, as defined below.

A critical accounting policy is defined as one that is both material to the presentation of our financial statements and requires management to make difficult, subjective or complex judgments that could have a material effect on our financial condition and results of operations. Specifically, critical accounting estimates have the following attributes: (1) we are required to make assumptions about matters that are highly uncertain at the time of the estimate; and (2) different estimates we could reasonably have used, or changes in the estimate that are reasonably likely to occur, would have a material effect on our financial condition or results of operations.

Estimates and assumptions about future events and their effects cannot be determined with certainty. We base our estimates on historical experience and on various other assumptions believed to be applicable and reasonable under the circumstances. These estimates may change as new events occur, as additional information is obtained and as our operating environment changes. These changes have historically been minor and have been included in the financial statements as soon as they became known. Based on a critical assessment of our accounting policies and the underlying judgments and uncertainties affecting the application of those policies, management believes that our financial statements are fairly stated in accordance with U.S. GAAP and present a meaningful presentation of our financial condition and results of operations. We believe the following critical accounting policies reflect our more significant estimates and assumptions used in the preparation of our consolidated financial statements:

The preparation of our consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amount of revenues and expenses during the reporting period. In the accompanying consolidated financial statements, estimates are used for, but not limited to, the impairment assessment of goodwill, the fair value of warrant liability, the fair value of stock-based compensation, allowance for inventory obsolescence, contingent liabilities, fair value and depreciable lives of long-lived assets, and deferred taxes and associated valuation allowance. Actual results could differ from those estimates.

Fair value is defined as the price that would be received in the sale of an asset or that would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company has categorized all investments recorded at fair value based upon the level of judgment associated with the inputs used to measure their fair value.

Hierarchical levels, directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities, are as follows:

The Company’s financial instruments (cash and cash equivalents, receivables, accounts payable and accrued liabilities) are carried in the consolidated balance sheet at cost, which reasonably approximates fair value based on their short-term nature. The Company’s warrant liability is recorded at fair value, with changes in fair value being reflected in the statements of operations for the period of change. The fair value of the term loan approximates its face value of $0.6 million based on the Company’s current financial condition and on the variable nature of term loan’s interest feature as compared to current rates.

Costs incurred in connection with research and development activities are expensed as incurred. Research and development expenses consist of direct and indirect costs associated with specific projects, manufacturing activities, and include fees paid to various entities that perform research related services for the Company.

The Company recognizes expense in the consolidated statements of operations for the fair value of all stock-based compensation to key employees, nonemployee directors and advisors, generally in the form of stock options and stock awards. The Company uses the Black-Scholes option valuation model to estimate the fair value of stock options on the grant date. Compensation cost is amortized on a straight-line basis over the vesting period for each respective award. The Company accounts for forfeitures as they occur.

For a discussion of significant accounting guidance recently adopted or unadopted accounting guidance that has the potential of being significant, see Note 3 of the Notes to the Consolidated Financial Statements included elsewhere herein.

Total revenues were $0.03 million and $0.6 million for the years ended December 31, 2020 and 2019, respectively. All the revenue recognized in 2020 and 2019 is attributable to work performed under a federal grant from the National Institutes of Health grant which came to an end in the second quarter of 2020.

Total operating expenses were $13.5 million during the year ended December 31, 2020, a 9% decrease from operating expenses of $14.8 million during the year ended December 31, 2019. Operating expenses for the years ended December 31, 2020 and 2019 were as follows:

Research and development expenses totaled $4.3 million for the year ended December 31, 2020, compared to $4.7 million for the year ended December 31, 2019, reflecting continued product development and manufacturing activities for VAZALORE. This decrease was due to 2020 activities which included the bioequivalence study to provide data for the sNDA filing, stability and validation work compared to manufacture, packaging, stability, and analytical costs related to the registration batches in 2019. We expect the research and development costs to be about the same in 2021 as manufacturing activities continue with the development and stability of VAZALORE.

General and administrative expenses totaled $9.2 million for the year ended December 31, 2020, compared to $10.0 million for the year ended December 31, 2019. The decrease is due to lower compensation related expenses combined with savings from COVID-19 restrictions on conference and travel costs. We expect our selling, general and administrative expenses to increase as a result of the expected commercial launch of VAZALORE.

Other expense totaled $1.8 million for the year ended December 31, 2020, compared to $6.3 million for the year ended December 31, 2019. The change is primarily attributable to the non-cash change in fair value of warrant liability primarily due to the fluctuation of the price of the Company’s common stock ($1.4 million of other expense for the year ended December 31, 2020, as compared to $5.7 million of other expense in the prior year).

The following table summarizes the primary uses and sources of cash for the periods indicated:

Net cash used in operating activities was $12.2 million and $12.7 million for the years ended December 31, 2020 and 2019, respectively. The decrease was due to lower compensation and COVID-19 impacted conference and travel costs offset somewhat by the increase in the settlement of 2019 year-end liabilities in 2020.

Net cash used in investing activities totaled $0.1million and $0.2 million for the years ended December 31, 2020 and 2019, respectively, and reflects the purchase of manufacturing equipment for VAZALORE.

Net cash provided by financing activities totaled $20.8 million and $12.6 million for the years ended December 31, 2020 and 2019, respectively, and reflects $7.7 million net proceeds from the issuance of Series B Preferred Stock and $16.8 million net proceeds from the issuance of common stock in the 2020 period, which was higher than the net proceeds of $13.7 million from the issuance of Series A Preferred Stock and $2.1 million net proceeds from the sale of common stock in the prior year. The current year period also includes higher payments of the Term Loan as the prior year period reflected two less payments due to the start of the payment amortization period.

As of December 31, 2020, we had working capital of $19.4 million, including cash and cash equivalents of $22.4 million. In addition, during March 2019, we entered into an equity distribution agreement (the "Equity Distribution Agreement") with JMP Securities, Inc. (“JMP”) to issue and sell shares of our common stock, having an aggregate offering price of up to $12.5 million, from time to time during the term of the Equity Distribution Agreement, through an “at-the-market” equity offering program (the “ATM Offering”) at our sole discretion, under which JMP acted as our agent. At December 31, 2020, we had $10.2 million available under this ATM Offering. The JMP Equity Distribution Agreement and related ATM Offering was terminated on March 2, 2021.

On March 5, 2021 the Company completed an underwritten public offering (the “Public Offering”) in which we issued 7,875,000 shares of our common stock at a price to the public of $8.00 per share. Gross proceeds of the Public Offering were $63 million, before deducting underwriting discounts and commissions and other offering expenses payable by the Company. Net proceeds of the Public Offering were $59 million. The underwriters retained a 30-day option to purchase up to 1,181,250 shares of common stock at the public offering price, less underwriting discounts and commission.

We have not generated any revenue from the sale of products and have incurred operating losses in each year since we commenced operations. As of December 31, 2020, we had an accumulated deficit of $102.1 million. We expect to continue to incur significant operating expenses and operating losses for the foreseeable future as we continue the development and commercialization of VAZALORE. Although these losses and expected losses give rise to substantial doubt, the Company's cash on hand at December 31, 2020 combined with the proceeds from the Public Offering support that the Company can fund its obligations for at least one year from the date these financial statements were issued and mitigate the substantial doubt consideration.

Our prior losses, combined with expected future losses, have had and will continue to have an adverse effect on our stockholders’ equity and working capital. If we are unable to achieve and sustain profitability, the market value of our common stock will likely decline. Because of the numerous risks and uncertainties associated with developing biopharmaceutical products, we are unable to predict the extent of any future losses or when, if ever, we will become profitable. We may need to obtain additional financing in the future, in addition to the proceeds from the Public Offering, to execute our commercialization plan. We may obtain additional financing through public or private equity offerings, debt financings (including related-party financings), a credit facility or strategic collaborations.

Additional financing may not be available to us when we need it or it may not be available to us on favorable terms, if at all. Our failure to raise capital as and when needed could have a negative impact on our financial condition and our ability to pursue our business strategies. We currently have no understandings, commitments or agreements relating to any of these types of transactions, other than in connection with the underwriters' over-allotment option as part of the Public Offering. If we are unable to raise additional funds when needed, we may be required to sell or license our technologies or clinical product candidates or programs that we would prefer to develop and commercialize ourselves.

On March 11, 2020, the World Health Organization declared the outbreak of COVID-19 as a “pandemic”, or a worldwide spread of a new disease. Many countries imposed quarantines and restrictions on travel and mass gatherings to slow the spread of the virus and have closed non-essential businesses.

In response to COVID-19, the Company has not experienced a disruption or delay in the development of VAZALORE™. However, the extent to which COVID-19 may impact our business will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the duration of the pandemic, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the pandemic.

The Company has not experienced any significant negative impact on the December 31, 2020 audited consolidated financial statements related to COVID-19. For more discussion on our risks related to COVID-19, please see risk factors included under “Item 1A. Risk Factors” herein.

The Company believes that the rates of inflation in recent years have not had a significant impact on its operations.

The Company did not have any off-balance sheet arrangements as of December 31, 2020 or 2019.

Our consolidated financial statements and supplementary data required to be filed pursuant to this Item 8 are listed in Item 15 of this Form 10-K beginning on page F-1 and are incorporated herein by reference.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE.

As of the end of the period covered by this Form 10-K, under the supervision and with the participation of management, including the Chief Executive Officer and the Chief Financial Officer of the Company (collectively, the “Certifying Officers”), the Company conducted an evaluation of its disclosure controls and procedures. As defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, the term “disclosure controls and procedures” means controls and other procedures of an issuer that are designed to ensure that information required to be disclosed by the issuer in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including the Certifying Officer, to allow timely decisions regarding required disclosure. Based on this evaluation, our Certifying Officers have concluded that, as of December 31, 2020, our disclosure controls and procedures were effective.

Our management is responsible for establishing and maintaining adequate internal control over our financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act as a process designed by, or under the supervision of, a company’s principal executive and principal financial officers and effected by a company’s board of directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. GAAP. Our internal control over financial reporting includes those policies and procedures that:

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management, including the Company’s principal executive officer and principal financial officer, does not expect that the Company’s internal controls will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, 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. Because of the inherent limitations in all control systems, no evaluation of internal controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. Also, any evaluation of the effectiveness of controls with respect to future periods is subject to the risk that those internal controls may become inadequate because of changes in business conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Based on its evaluation of the Company’s internal control over financial reporting as of December 31, 2020, using the criteria set forth by COSO in Internal Control — Integrated Framework (2013), our management has concluded that, as of December 31, 2020, our internal control over financial reporting was effective based on those criteria.

This Form 10-K does not include an attestation report of our independent registered public accounting firm regarding internal control over financial reporting. Pursuant to Item 308(b) of Regulation S-K, management’s report is not subject to attestation by our independent registered public accounting firm because the Company is neither an “accelerated filer” nor a “large accelerated filer” as those terms are defined by the SEC.

We have not experienced any material impact to our internal controls over financial reporting despite the fact that most of our employees are working remotely due to the COVID-19 pandemic. We are continually monitoring and assessing the COVID-19 situation on our internal controls to minimize the impact on their design and operating effectiveness.

Information required by this Item will be set forth in our definitive proxy statement for our 2021 annual meeting, to be filed with the SEC pursuant to Regulation 14A no later than 120 days after the close of our fiscal year, and is incorporated herein by reference.

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE.

The consolidated balance sheets of the Company as of December 31, 2020 and 2019, the related consolidated statements of operations, changes in temporary equity and stockholders’ equity (deficit), and cash flows for each of the years ended December 31, 2020 and 2019, the footnotes thereto, and the reports of Marcum LLP, independent registered public accounting firms, are set forth on pages F-1 through F-21 of this Form 10-K.

See Exhibit Index of this Form 10-K for a description of the exhibits filed as part of, or incorporated by reference in, this Form 10-K.

All schedules have been omitted because they are not applicable or the required information is included in the consolidated financial statements or notes thereto.

We have audited the accompanying consolidated balance sheets of PLx Pharma Inc. (the “Company”) as of December 31, 2020 and 2019, the related consolidated statements of operations, changes in series A and series B convertible preferred stock and stockholders’ deficit and cash flows for each of the two years in the period ended December 31, 2020, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's 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 in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the 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 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

As discussed in Note 8 to the consolidated financial statements, the Company’s warrant liability is determined using a binomial asset pricing model that consisted of a conditional probability weighted expected return method that values the Company’s equity securities assuming various possible future outcomes to estimate the allocation of value within one or more of the scenarios. Using this method, unobservable assumptions included the Company’s equity value, expected timing of possible outcomes, risk free interest rates and stock price volatility. As of December 31, 2020, the stock price volatility used to determine the warrant liability is 92%.

We identified the evaluation of the stock price volatility used to determine the Company’s warrant liability as a critical audit matter. Evaluating the Company’s stock price volatility relating to its warrant liability is highly subjective and requires a higher degree of auditor judgment as the Company’s stock price volatility was determined by using comparable peer companies. Further, specialized valuation skills were needed to assess the Company’s process and evaluate the stock price volatility used in the determination of the warrant liability and the impact of the stock price volatility on the binomial asset pricing model.

The primary procedures we performed to address this critical audit matter included the following:

NOTE 3. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis and Accounting and Principles of Consolidation

The Company prepares its consolidated financial statements in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”).

The accompanying consolidated financial statements include the accounts of the Company and its direct and indirect wholly-owned subsidiaries, PLx Opco Inc. and PLx Chile SpA. All significant intercompany balances and transactions have been eliminated within the consolidated financial statements. The Company dissolved its subsidiary, PLx Chile SpA, in March 2020. The Company operates in one business segment.

Use of Estimates

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. The Company maintains cash and cash equivalents in a financial institution that at times exceeds federally insured limits. Management believes that the Company’s credit risk exposure is mitigated by the financial strength of the banking institution in which the deposits are held. As of December 31, 2020, the Company had cash and cash equivalents of $22.4 million in U.S. bank accounts which were not fully insured by the Federal Deposit Insurance Corporation.

Allowance for Uncollectible Accounts Receivable

An allowance for uncollectible accounts receivable is estimated based on historical experience, credit quality, age of the accounts receivable balances, and economic conditions that may affect a customer’s ability to pay. The allowance for uncollectible accounts receivable was zero as of December 31, 2020 and 2019, respectively.

Inventory

Inventory is stated at the lower of cost or net realizable value, using the average cost method. Inventory as of December 31, 2020 and 2019 was comprised of raw materials for the manufacture of VAZALORE™. The Company regularly reviews inventory quantities on hand and assesses the need for an allowance for obsolescence. The allowance for obsolete inventory was $0 and $0.5 million as of December 31, 2020 and 2019, respectively, resulting in net inventory of $0.1 million and $0, respectively.

F-9

Table of Contents

Fair Value of Financial Instruments

All financial instruments classified as current assets and liabilities are carried at cost, which approximates fair value, because of the short-term maturities of those instruments. The fair value of the term loan approximates its face value of $0.6 million based on the Company’s current financial condition and on the variable nature of the term loan’s interest feature as compared to current rates. For disclosures concerning fair value measurements, see Note 8.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. The Company capitalizes additions that have a tangible future economic life. Maintenance and repairs that do not improve or extend the lives of property and equipment are charged to operations as incurred. Depreciation expense is computed using the straight-line method over the estimated useful lives of each class of depreciable assets. Management reviews property and equipment for possible impairment whenever events or circumstances indicate the carrying amount of an asset may not be recoverable. If there is an indication of impairment, management prepares an estimate of future cash flows (undiscounted and without interest charges) expected to result from the use of the asset and its eventual disposition. If these cash flows are less than the carrying amount of the asset, an impairment loss is recognized to write down the asset to its estimated fair value.

Leases

At the inception of a contract, the Company determines if the arrangement is, or contains, a lease. Right-of-use (“ROU”) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Rent expense is recognized on a straight-line basis over the lease term.

The Company has made certain accounting policy elections whereby the Company (i) does not recognize ROU assets or lease liabilities for short-term leases (those with original terms of 12-months or less) and (ii) combines lease and non-lease elements of its operating leases. Operating lease ROU assets are included in right of use assets and operating lease liabilities are included in other current and non-current liabilities in the Company’s consolidated balance sheets. As of December 31, 2020 and 2019, the Company did not have any finance leases.

Goodwill

Goodwill is not amortized but is subject to periodic review for impairment. Goodwill is reviewed annually, as of October 31, and whenever events or changes in circumstances indicate that the carrying amount of the goodwill might not be recoverable. Management performs its review of goodwill on its one reporting unit.

The Company performs a one-step test in its evaluation of the carrying value of goodwill, if qualitative factors determine it is necessary to complete a goodwill impairment test. In the evaluation, the fair value of the relevant reporting unit is determined and compared to the carrying value. If the fair value is greater than the carrying value, then the carrying value is deemed to be recoverable, and no further action is required. If the fair value estimate is less than the carrying value, goodwill is considered impaired for the amount by which the carrying amount exceeds the reporting unit’s fair value, and a charge is reported in impairment of goodwill in the Company’s consolidated statements of operations.

The Company has not identified any events or changes in circumstances that indicate that a potential impairment of goodwill occurred during the years ended December 31, 2020 or 2019.

Revenue Recognition

The Company analyzes contracts to determine the appropriate revenue recognition using the following steps: (i) identification of contracts with customers; (ii) identification of distinct performance obligations in the contract; (iii) determination of contract transaction price; (iv) allocation of contract transaction price to the performance obligations; and (v) determination of revenue recognition based on timing of satisfaction of the performance obligation. The Company recognizes revenues upon the satisfaction of its performance obligations (upon transfer of control of promised goods or services to customers) in an amount that reflects the consideration to which it expects to be entitled to in exchange for those goods or services. Deferred revenue results from cash receipts from or amounts billed to customers in advance of the transfer of control of the promised services to the customer and is recognized as performance obligations are satisfied. When sales commissions or other costs to obtain contracts with customers are considered incremental and recoverable, those costs are deferred and then amortized as selling and marketing expenses on a straight-line basis over an estimated period of benefit.

The Company’s sole revenue arrangement is a cost-reimbursable federal grant with the National Institutes of Health. This federal grant was completed in the second quarter of 2020. The Company recognizes revenue on this grant as grant-related expenses are incurred by the Company or its subcontractors. The Company recognized $0.03 million and $0.6 million of revenue under this arrangement during the years ended December 31, 2020 and 2019, respectively.

The Company has not incurred incremental costs to obtain contracts with customers or material costs to fulfill contracts with customers and did not have any material contract assets or liabilities as of December 31, 2020 and December 31, 2019.

Research and Development Expenses

Stock-Based Compensation

The Company recognizes expense in the consolidated statements of operations for the fair value of all stock-based compensation to key employees, nonemployee directors and advisors, generally in the form of stock options. The Company uses the Black-Scholes option valuation model to estimate the fair value of stock options on the grant date. Compensation cost is amortized on a straight-line basis over the vesting period for each respective award. The Company accounts for forfeitures as they occur.

Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the expected future tax consequences attributable to temporary differences between financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is established when necessary to reduce deferred income tax assets to the amount expected to be realized.

Tax benefits are initially recognized in the financial statements when it is more likely than not that the position will be sustained upon examination by the tax authorities. Such tax positions are initially, and subsequently, measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement with the tax authority, assuming full knowledge of the position and all relevant facts.

The Company currently has tax returns open for examination by the applicable taxing authority for all years since 2015.

Income (Loss) Per Share

In periods of net loss, basic loss per share is computed by dividing net loss available to common stockholders by the weighted average number of shares of common stock outstanding during the period. The Series A and Series B convertible preferred stock (the “Series A Preferred Stock” and the “Series B Preferred Stock”) contains non-forfeitable rights to dividends, and therefore are considered to be participating securities; in periods of net income, the calculation of basic earnings per share excludes from the numerator net income attributable to the Series A Preferred Stock and Series B Preferred Stock and excludes the impact of those shares from the denominator.

In periods of net loss, diluted loss per share is calculated similarly to basic loss per share because the impact of all potential dilutive common shares is anti-dilutive. In periods of net income, diluted earnings per share is computed using the more dilutive of the “two class method” or the “treasury method.” Dilutive earnings per share under the “two class method” is calculated by dividing net income available to common stockholders as adjusted for the participating impacts of the Series A Preferred Stock and Series B Preferred Stock, by the weighted-average number of shares outstanding plus the dilutive impact of all other potential dilutive common shares, consisting primarily of common shares underlying common stock options and stock purchase warrants using the treasury stock method. Dilutive earnings per share under the “treasury method” is calculated by dividing net income available to common stockholders by the weighted-average number of shares outstanding plus the dilutive impact of all potential dilutive common shares, consisting primarily of common shares underlying common stock options and stock purchase warrants using the treasury stock method, and convertible preferred stock using the if-converted method.

F-11

Table of Contents

None of the potential dilutive securities had a dilutive impact during the years ended December 31, 2020 and 2019.

The number of anti-dilutive shares for the years ended December 31, 2020 and 2019 was 20.3 million and 10.5 million, respectively, consisting of common shares underlying (i) common stock options of 3.0 million and 1.7 million, respectively, (ii) stock purchase warrants of 7.9 million and 2.7 million, respectively, and (iii) convertible preferred stock of 9.4 million and 6.2 million which have been excluded from the computation of diluted income per share.

Recent Accounting Developments

Unadopted Guidance

In August 2020, the Financial Accounting Standards Board issued Accounting Standards Update 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) that provides new guidance on the accounting for convertible debt instruments and contracts in an entity’s own equity. The guidance simplifies the accounting for convertible instruments by reducing the various accounting models that can require the instrument to be separated into a debt component and equity component or derivative component. Additionally, the guidance eliminated certain settlement conditions previously required to be able to classify a derivative in equity. The new guidance is effective on a modified or full retrospective basis for fiscal years beginning after December 15, 2023, including interim periods with those fiscal years. The Company will evaluate the impact on the consolidated financial statements.

In November 2019, the Financial Accounting Standards Board (“FASB”) issued guidance (ASU 2019-12) simplifying the accounting for income taxes by removing the following exceptions: 1) exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items, 2) exception requirement to recognize a deferred tax liability for equity method investments when a foreign subsidiary becomes an equity method investment, 3) exception to the ability not to recognize a deferred tax liability for a foreign subsidiary when a foreign equity method investment becomes a subsidiary, and 4) exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss the year. The amendments also simplify accounting for income taxes by doing the following: 1) requiring that an entity recognize a franchise tax or similar tax that is partially based on income as an income-based tax and account for any incremental amount incurred as a non-income-based tax, 2) requiring that an entity evaluate when a step up in the tax basis of goodwill should be considered part of the business combination in which the book goodwill was originally recognized and when it should be considered a separate transaction, 3) specifying that an entity is not required to allocate the consolidated amount of current and deferred tax expense to a legal entity that is not subject to tax in its separate financial statements, 4) requiring that an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date, and 5) making minor Codification improvements for income taxes related to employee stock ownership plans and investments in qualified affordable housing projects accounted for using the equity method. The guidance is effective for reporting periods beginning after December 15, 2020, including interim periods within that fiscal year. Early adoption was permitted, including adoption in an interim period. The Company does not expect the adoption of ASU 2019-12 will have a material impact on its financial position, results of operations and cash flows.

The Company does not believe that any other recently issued effective standards, or standards issued but not yet effective, if adopted, would have a material effect on the accompanying consolidated financial statements.

Reclassifications

Certain reclassifications have been made to the prior-year financial statements to conform to the current-year presentation. These reclassifications had no effect on the reported results of operations.

Subsequent Events

The Company’s management reviewed all material events through the date the consolidated financial statements were issued for subsequent event disclosure consideration.

NOTE 6. STOCKHOLDERS’ EQUITY

Common Stock

In November 2020, the Company entered into a securities purchase agreement for the sale of units comprised of shares of common stock and a warrant to purchase shares of common stock in a private placement that resulted in gross proceeds to the Company of $18.0 million and net proceeds of $16.8 million after deducting placement agent and other offering expenses, for the issuance of 4,755,373 shares of common stock and warrants to purchase up to an additional 5,230,910 shares of common stock for a per unit price of $3.787. The private placement closed on November 18, 2020. The warrants will become exercisable on the date of issuance, have an exercise price of $4.31 per share and will expire five years from the date of issuance.

Equity Distribution Agreement

In March 2019, the Company entered into the Equity Distribution Agreement with JMP. Pursuant to the terms of the Equity Distribution Agreement, the Company was able to sell from time to time, at its option, shares of the Company’s common stock, through JMP, as sales agent, with an aggregate sales price of up to $12.5 million. Any sales of shares pursuant to the Equity Distribution Agreement were made under the Company’s effective “shelf” registration statement, which allowed it to sell debt or equity securities in one or more offerings up to a total public offering price of $75 million. In 2019, the Company issued 398,709 shares under the Equity Distribution Agreement generating gross proceeds of $2.3 million and net proceeds of $2.1 million after deducting legal and commission costs. There have been no issuances in 2020 under the Equity Distribution Agreement. As of December 31, 2020, $10.2 million remained available under the ATM Offering. Effective March 2, 2021, the Equity Distribution Agreement and ATM Offering was terminated.

Convertible Preferred Stock

Series A Preferred Stock

In December 2018, the Company entered into a purchase agreement with certain accredited investors for the private placement of $15.0 million of Series A Convertible Preferred Stock, par value $0.001 per share (the “Series A Preferred Stock”) pending stockholders’ approval, which approval was subsequently obtained on February 19, 2019. Accordingly, the Company completed the private placement on February 20, 2019, raising $15.0 million through the issuance of 15,000 shares of Series A Preferred Stock. The Series A Preferred Stock was issued at $1,000 per share and is convertible into common shares at a conversion price of $2.60 per share, subject to certain adjustments. Holders of the Series A Preferred Stock will be entitled to an initial dividend rate of 8.0% per annum, which will stop accruing on the date of the FDA’s approval of the supplemental sNDA of VAZALORE 325 mg and VAZALORE 81mg. The dividends are compounded quarterly and payable in cash or shares of Series A Preferred Stock at the Company’s option. The Series A Preferred Stock carries a liquidation preference equal to its stated value of $1,000 plus accrued and unpaid dividends. The Series A Preferred Stock is classified as temporary equity due to the presence of certain contingent cash redemption features. As a result of the excess value of the Company’s common stock on the issuance date over the conversion price of the Series A Preferred Stock, a beneficial conversion feature in the amount of $12.7 million was bifurcated from the host instrument and accounted for separately as an increase in additional paid-in capital in equity, and resulted in a deemed dividend during the year ended December 31, 2019 of $12.7 million which was accounted for as a decrease in additional paid-in capital in equity due to the Company’s accumulated deficit position. At December 31, 2020, the carrying value of the temporary equity was $13.7 million, net of $1.3 million in offering costs.

The Company recognized $1.3 million (or $0.14 per share) of total dividends on the Series A Preferred Stock during the year ended December 31, 2020. The Company recognized $1.1 million (or $0.12 per share) of total dividends on the Series A Preferred Stock during the year ended December 31, 2019.

Series B Preferred Stock

In March 2020, the Company entered into a purchase agreement with certain accredited investors for the private placement of $8.0 million of Series B Preferred Stock pending stockholders' approval, which approval was subsequently obtained on May 15, 2020. Accordingly, the Company completed the private placement on May 15, 2020, raising $8.0 million through the issuance of 8,000 shares of Series B Preferred Stock. The Series B Preferred Stock was issued at $1,000 per share and is convertible into common shares at a conversion price of $3.10 per share, subject to certain adjustments. Holders of the Series B Preferred Stock are entitled to an initial dividend rate of 8.0% per annum, which will stop accruing on the date of the FDA’s approval of the supplemental NDA of VAZALORE 325 mg and VAZALORE 81mg. The dividends are compounded quarterly and payable in cash or shares of Series B Preferred Stock at the Company’s option. The Series B Preferred Stock carries a liquidation preference equal to its stated value of $1,000 plus accrued and unpaid dividends.

The Series B Preferred Stock is classified as temporary equity due to the presence of certain contingent cash redemption features. At December 31, 2020, the carrying value of the temporary equity was $7.7 million, net of $0.3 million in offering costs.

The Company recognized $0.4 million (or $0.04 per share) of total dividends on the Series B Preferred Stock during the year ended December 31, 2020. No dividends were recognized on common stock during any of the periods presented.

Warrants

In June 2017, the Company issued stock purchase warrants to purchase 2,646,091 shares of common stock at an exercise price of $7.50 per share. The warrants, exercisable beginning six months and one day after issuance, have a 10-year term, contain a cashless exercise provision, and are liability classified due the holders’ right to require the Company to repurchase the warrants for cash upon certain deferred fundamental transactions. See Note 8 for the fair value measurement of the warrant liability.

In connection with the entry into the Term Loan Facility, the Company issued to SVB and one of its affiliates stock purchase warrants to purchase an aggregate of 58,502 shares of the Company’s common stock at an exercise price of $6.41 per share (see Note 5). These warrants are immediately exercisable, have a 10-year term, contain a cashless exercise provision, and are classified in equity.

In November 2020, the Company issued warrants to purchase 5,230,910 shares of common stock which have an exercise price of $4.31 per share, contain a cashless exercise provision, will expire five years from the date of issuance and are equity classified.

On September 13, 2018, the Company’s stockholders approved the 2018 Incentive Plan (the “2018 Plan”). The 2018 Plan provides that the Company may grant equity interests to employees, consultants, and members of the Board of Directors in the form of incentive and nonqualified stock options, restricted stock and restricted stock units, stock appreciation rights and various other forms of stock-based awards. On November 10, 2020, the Company held its 2020 annual meeting of stockholders at which the Company’s stockholders approved an amendment to the 2018 Plan, to increase the number of shares of the Company’s common stock issuable under the 2018 Plan by 1,750,000 shares (the “Plan Amendment”). The Board of Directors of the Company previously approved the Plan Amendment on September 23, 2020, subject to stockholder approval. There are 3,000,000 shares authorized to be issued pursuant to the 2018 Plan, of which 957,650 shares are available for issuance under the 2018 Plan.

Patent License Agreement with the Board of Regents of the University of Texas (NSAIDs)

On January 8, 2003, the Company entered into a patent license agreement with the Board of Regents of The University of Texas System (“UT”), under which it acquired an exclusive license for several patents and patent applications both inside and outside of the United States relating to gastrointestinal safer formulations of NSAIDs. Additionally, the Company acquired worldwide rights to commercialize licensed products which allow for the Company to grant sublicenses subject to royalty payments.

Under terms of the agreement, the Company is responsible for conducting clinical trials involving investigational use of a licensed product for the determination of metabolic and pharmacologic actions in humans, the side effects associated with increasing doses, examination of suspected indications, determination of the potential short-term side effects in humans and for establishing the safety, efficacy, labeled indications and risk-benefit profile in humans. The patent license agreement also requires the Company to provide reimbursement for all expenses incurred by The University of Texas Health Science Center at Houston for filing, prosecuting, enforcing, and maintaining patent rights and requires an annual nonrefundable license management fee. In addition, the Company is obligated to pay certain milestone payments in future years relating to royalties resulting from the approval to sell licensed products and the resulting sales of such licensed products. The Company recognized total expenses of $0.3 million and $0.4 million related to the UT in the years ended December 31, 2020 and 2019, respectively.

NOTE 8. FAIR VALUE MEASUREMENTS

Hierarchical levels, directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and liabilities, are as follows:

	●	Level 1: Quoted prices in active markets for identical assets or liabilities that the organization has the ability to access at the reporting date.
	●	Level 2: Inputs other than quoted prices included in Level 1, which are either observable or that can be derived from or corroborated by observable data as of the reporting date.

F-17

Table of Contents

●

Level 3: Inputs include those that are significant to the fair value of the asset or liability and are generally less observable from objective resources and reflect the reporting entity’s subjective determinations regarding the assumptions market participants would use in pricing the asset or liability.

Financial assets and liabilities measured at fair value on a recurring basis

The Company evaluates financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level at which to classify them each reporting period. This determination requires the Company to make subjective judgments as to the significance of inputs used in determining fair value and where such inputs lie within the hierarchy.

The stock purchase warrants issued in June 2017 contain certain cash settlement features and, accordingly, the Company considered them to be liabilities and accounted for them at fair value using Level 3 inputs. The Company determined the fair value of this warrant liability using a binomial asset pricing model that consisted of a conditional probability weighted expected return method that values the Company’s equity securities assuming various possible future outcomes to estimate the allocation of value within one or more of the scenarios. Using this method, unobservable inputs included the Company’s equity value, expected timing of possible outcomes, risk free interest rates and stock price volatility.

The following table sets forth a summary of changes in the fair value of Level 3 liabilities measured at fair value on a recurring basis for the years ended December 31, 2020 and 2019:

Effective income tax rate		0.0	%		0.0	%

The Company had net operating loss carry-forwards of $97.7 million as of December 31, 2020, that may be offset against future taxable income. The carry-forwards will begin to expire in 2035. Use of these carry-forwards may be subject to annual limitations based upon previous significant changes in stock ownership. The Company does not believe that it has any uncertain income tax positions.

Utilization of NOL and tax credit carryforwards may be subject to a substantial annual limitation due to ownership change limitations that may have occurred or that could occur in the future, as required by the Internal Revenue Code (the “Code” and “IRC”), as amended, as well as similar state provisions. In general, an ownership change as defined by the Code results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percent of the outstanding common stock of a company by certain stockholders or public groups. The Company experienced an ownership change within the meaning of IRC Section 382 during the year ended December 31, 2017. As a result, certain limitations apply to the annual amount of net operating losses that can be used to offset post ownership change taxable income.

As of December 31, 2020, the tax returns for the years from 2015 through 2019 remain open to examination by the Internal Revenue Service and various state authorities. ASC 740, “Income Taxes” requires that a valuation allowance is established when it is more likely than not that all, or a portion of, deferred tax assets will not be recognized. A review of all available positive and negative evidence needs to be considered, including the Section 382 limitation, the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies. After consideration of all the information available, management believes that uncertainty exists with respect to the future realization of its deferred tax assets and has, therefore, established a full valuation allowance as of December 31, 2020, and 2019. For the year ended December 31, 2020, the change in valuation allowance was $4.3 million.

As of December 31, 2020, and 2019, the Company has evaluated and concluded that there were no material uncertain tax positions requiring recognition in the Company’s financial statements. The Company’s policy is to classify assessments, if any, for tax-related interest as income tax expenses. No interest or penalties were recorded during the years ended December 31, 2020 and 2019. The Company does not expect its unrecognized tax benefit position to change during the next twelve months.
