Conference call and live webcast scheduled for Monday, August 10, 2020 at 8:30 am ET

CARMIEL, Israel, August 10, 2020 /PRNewswire/Protalix BioTherapeutics, Inc. (NYSE American:PLX) (TASE:PLX), a biopharmaceutical company focused on the development, production and commercialization of recombinant therapeutic proteins produced by its proprietary ProCellEx^® plant cell-based protein expression system, today reported financial results for the second quarter ended June 30, 2020, and provided a business update on recent corporate and clinical developments.

“This quarter, we delivered on two very important milestones for the company: announcing positive topline results in our BRIDGE phase III clinical trial of PRX-102 for the treatment of Fabry disease and subsequent BLA submission to the U.S. Food and Drug Administration (FDA). We were able to accomplish these goals even as we faced the challenging headwinds from the global COVID-19 pandemic, and I am very proud of our entire team for their commitment and dedication,” said Dror Bashan, Protalix’s President and Chief Executive Officer. “As we look towards an exciting second half of the year, we are continuing to build Protalix for the long term. We augmented our research and development team with highly qualified and seasoned veterans to support and enhance our pipeline, and we announced a new partnership to explore the development of PRX-110.” Mr. Bashan concluded, “We are gratified to have a balance sheet supporting our strategic plans and look forward to continuing to execute as we move towards the anticipated commercial launch of PRX-102 for the treatment of Fabry disease.”

Recent Business Highlights

· Submitted a Biologics License Application (BLA) to the FDA for PRX-102 (pegunigalsidase alfa) for the treatment of adult patients with Fabry disease on May 27, 2020. The BLA was submitted under the FDA’s accelerated approval pathway in collaboration with the Company’s development and commercialization partner, Chiesi Farmaceutici S.p.A. On July 28, 2020, the FDA informed Chiesi that the BLA had been filed for review and that the FDA was working on the 74-day letter. In addition, the FDA informed Chiesi that no “Refuse To File” will be issued for the PRX-102 BLA.

· Announced positive topline results from our BRIDGE Phase III clinical trial of PRX-102 for the treatment of Fabry disease. The study was an open-label, switch-over trial designed to evaluate the safety and efficacy of 1 mg/kg PRX-102 infused every two weeks, in Fabry patients. The trial met its main objectives for safety and efficacy, and topline analysis indicated substantial improvement in renal function as measured by mean annualized estimated Glomerular Filtration Rate (eGFR slope) in patients switched from agalsidase alfa to PRX-102.

· Enhanced the executive management team with the appointment of Yael Hayon, Ph.D. as Vice President, Research and Development. Dr. Hayon brings over a decade of pharmaceutical research and development experience in both the scientific operations and administrative functions.

· Entered into a non-binding term sheet with SarcoMed USA, Inc. to explore the development and commercialization of PRX-110 (alidornase alfa) in the treatment of Pulmonary Sarcoidosis and related diseases. SarcoMed USA was formed in 2017 to investigate if a novel DNase 1 compound could influence the chronic pulmonary inflammation seen in Pulmonary Sarcoidosis patients.

Second Quarter 2020 Financial Highlights

The Company recorded revenues from selling goods of $3.6 million during the three months ended June 30, 2020, an increase of $0.2 million, or 6%, compared to revenues of $3.4 million for the same period of 2019.

Revenues from license and R&D services for the three months ended June 30, 2020, were $7.3 million, a decrease of $1.5 million, or 17%, compared to revenues of $8.8 million for the same period of 2019. Revenues from license and R&D services are comprised primarily of revenues the Company recognized in connection with its license and supply agreements with Chiesi. The decrease is primarily due to the completion of two out of the three phase III clinical trials of PRX-102 as well as lower costs related to the Company’s phase III BALANCE clinical trial of PRX-102 for the treatment of Fabry disease.

Cost of goods sold was $1.8 million for the three months ended June 30, 2020, a decrease of $0.9 million, or 32%, from cost of goods sold of $2.7 million for the same period of 2019. The decrease is primarily due to a change in the cost structure as well as lower royalties paid to the Israeli Innovation Authority.

Research and development expenses were $9.2 million for the three months ended June 30, 2020, a decrease of $4.1 million, or 31%, compared to $13.3 million of research and development expenses for the same period of 2019. The decrease is primarily due to the completion of two out of the three phase III clinical trials of PRX-102 and reduced costs related to the Company’s phase III BALANCE clinical trial as well as a decrease in costs related to manufacturing of the Company’s drug in development as some of the manufactured drug product and related costs have been recorded as inventory.

Selling, general and administrative expenses were $2.2 million for the three months ended June 30, 2020, an increase of $0.1 million, or 6%, compared to $2.1 million for the same period of 2019.

Cash and cash equivalents at June 30, 2020 was $4.8 million, with $35.2 million in bank deposits.

About Protalix BioTherapeutics, Inc.

Protalix is a biopharmaceutical company focused on the development and commercialization of recombinant therapeutic proteins expressed through its proprietary plant cell-based expression system, ProCellEx^®. Protalix was the first company to gain U.S. Food and Drug Administration (FDA) approval of a protein produced through plant cell-based in suspension expression system. Protalix’s unique expression system represents a new method for developing recombinant proteins in an industrial-scale manner.

Protalix’s first product manufactured by ProCellEx, taliglucerase alfa, was approved for marketing by the FDA in May 2012 and, subsequently, by the regulatory authorities of other countries. Protalix has licensed to Pfizer Inc. the worldwide development and commercialization rights for taliglucerase alfa, excluding Brazil, where Protalix retains full rights.

Protalix’s development pipeline consists of proprietary versions of recombinant therapeutic proteins that target established pharmaceutical markets, including the following product candidates: pegunigalsidase alfa, a modified version of the recombinant human α-Galactosidase-A protein for the proposed treatment of Fabry disease; OPRX-106, an orally-delivered anti-inflammatory treatment; alidornase alfa for the treatment of Cystic Fibrosis; PRX-115, a plant cell-expressed recombinant PEGylated Uricase for the treatment of gout; and others. Protalix has partnered with Chiesi Farmaceutici S.p.A., both in the United States and outside the United States, for the development and commercialization of pegunigalsidase alfa.
