CARMIEL, Israel, Aug. 14, 2024 /PRNewswire/ -- Protalix BioTherapeutics, Inc. (NYSE American: 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 quarter ended June 30, 2024, and provided a business update.

"In the second quarter, Protalix has made meaningful progress on our early-stage pipeline," said Dror Bashan, Protalix's President and Chief Executive Officer. "Results from the first seven cohorts of the phase I clinical trial of PRX-115 for the treatment of uncontrolled gout are encouraging, and we anticipate topline results from all eight cohorts to be available in the third quarter of 2024. Based on the safety results to date, we have initiated preparations for a phase II clinical trial of PRX-115 in uncontrolled gout patients. Our strong balance sheet enables repayment of our convertible notes due September 2024 while maintaining ongoing operations and executing on our corporate strategy."

Second Quarter 2024 and Recent Business Highlights

Pipeline Developments

• In May 2024, the Company announced positive topline results from the First-in-Human (FIH) Phase I clinical trial of PRX-115, the Company's a recombinant PEGylated uricase product candidate in development as a potential treatment for uncontrolled gout.
        o  Results from the first seven dosing cohorts demonstrated that single administration of PRX-115 induced rapid, long-lasting reduction of plasma uric acid concentrations, a dose-dependent increase in exposure, and a favorable tolerability profile.
        o  Dosing of the eighth and highest dose cohort is complete, and topline results from the full trial are expected in the third quarter of 2024.

• In June 2024, the Company hosted an Investor Day highlighting current treatment landscapes and clinical results for Fabry disease and uncontrolled gout. The event featured presentations from key opinion leaders (KOLs) Aleš Linhart, D.Sc., FESC (Charles University, Prague) and Naomi Schlesinger, M.D. (University of Utah). The Company's leadership also provided insight into its strategy and future plans.

Second Quarter 2024 Financial Highlights

• The Company recorded revenues from selling goods of $13.3 million during the three months ended June 30, 2024, a decrease of $1.8 million, or 12%, compared to revenues of $15.1 million for the three months ended June 30, 2023. The decrease resulted primarily from a decrease of $10.0 million in sales to Chiesi, partially offset by an increase of $4.7 million in sales to Brazil and an increase of $3.5 million in sales to Pfizer. Sales to Chiesi in the three months ended June 30, 2023 were in connection with the commercial launch and inventory buildup of Elfabrio^® after its approval for marketing in the United States and the European Union. The increases in sales to Brazil and Pfizer during the three months ended June 30, 2024 resulted primarily from the timing of delivery.
• The Company recorded revenues from license and R&D services of $0.2 million for the three months ended June 30, 2024, a decrease of $19.8 million, or 99%, compared to revenues of $20.0 million for the three months ended June 30, 2023. Revenues from license and R&D services are comprised primarily of revenues the Company recognized in connection with the Chiesi Agreements. The revenues from license and R&D services for the three months ended June 30, 2023 were the result of the $20.0 million regulatory milestone payment from Chiesi in connection with the FDA approval of Elfabrio granted during that period.
• Cost of goods sold was $9.5 million for the three months ended June 30, 2024, an increase of $3.4 million, or 56%, from cost of goods sold of $6.1 million for the three months ended June 30, 2023. The increase in cost of goods sold was primarily the result of an increase in sales to Pfizer and to Brazil. In addition, during the three months ended June 30, 2023, a significantly higher portion of the costs for certain drug substance sold, as compared to the three months ended June 30, 2024, were recognized as research and development expenses, not cost of goods sold, as such drug substance was produced as part of the Company's research and development activities.
• For the three months ended June 30, 2024, the Company's total research and development expenses were approximately $3.0 million comprised of approximately $0.5 million in subcontractor-related expenses, approximately $1.6 million of salary and related expenses, approximately $0.2 million of materials-related expenses and approximately $0.7 million of other expenses. For the three months ended June 30, 2023, the Company's total research and development expenses were approximately $4.5 million comprised of approximately $1.7 million of subcontractor-related expenses, approximately $2.0 million of salary and related expenses, approximately $0.1 million of materials-related expenses and approximately $0.7 million of other expenses. Total decrease in research and developments expenses for the three months ended June 30, 2024 was $1.5 million, or 33%, compared to the three months ended June 30, 2023. The decrease in research and development expenses resulted primarily from the completion of the Company's Fabry clinical program and the regulatory processes related to the review of the Elfabrio Biologics License Application (BLA) in the United States and the Marketing Authorization Application (MAA) in the European Union by the applicable regulatory agencies.
• Selling, general and administrative expenses were $3.5 million for the three months ended June 30, 2024, a decrease of $0.5 million, or 13%, compared to $4.0 million for the three months ended June 30, 2023. The decrease resulted primarily from a decrease of $0.5 million in salary and related expenses.
• Financial income, net were $0.2 million for the three months ended June 30, 2024, compared to financial expenses, net of $0.8 million for the three months ended June 30, 2023. The difference resulted primarily from higher interest income on bank deposits and lower notes interest expenses due to notes conversions executed in 2023.
• For the three months ended June 30, 2024, the Company recorded a tax benefit of approximately $0.1 million, compared to income taxes of $0.3 million for the three months ended June 30, 2023. Income taxes recorded are primarily the result of the provision for current taxes in respect of Section 174 of the U.S. Tax Cuts and Jobs Act, which was enacted in December 2017.
• Cash, cash equivalents and short-term bank deposits were approximately $45.0 million at June 30, 2024.
• Net loss for the three months ended June 30, 2024 was approximately $2.2 million, or $0.03 per share, basic and diluted, compared to a net income of $19.3 million, or $0.29 per share, basic, and $0.21 per share, diluted, for the same period in 2023.
• Since the end of the quarter ended June 30, 2024, the Company collected approximately $4.6 million in the aggregate from sales to Pfizer Inc., and approximately $2.3 million from sales to Brazil.
