Protalix BioTherapeutics Reports First Quarter 2024 Financial and Business Results

Company to host conference call and webcast today at 8:30 a.m. EDT

CARMIEL, Israel, May 10, 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 March 31, 2024, and provided a business and clinical update.

“We are pleased to announce that initial top-line results from the first seven cohorts of the first-in-human phase I clinical trial of our recombinant uricase candidate, PRX-115, are encouraging, enabling us to expand into an eighth cohort and to begin planning a phase II trial,” said Dror Bashan, Protalix’s President and Chief Executive Officer. “We will analyze and announce the full results from the expanded trial following the completion of the new cohort. We believe that our strong cash position is sufficient to enable the repayment of our convertible notes due September 2024, and for our ongoing operations.”

First Quarter 2024 and Recent Business Highlights

Clinical Developments

The PRX-115 trial is a double blind, placebo-controlled, single ascending dose (SAD), First-in-Human phase I clinical trial of PRX-115 for the potential treatment of uncontrolled gout (the “FIH Study”) that the Company designed to evaluate the safety, pharmacokinetics (PK) and pharmacodynamics (PD; reduction of uric acid) following single dose of PRX-115 in subjects with elevated uric acid levels. Of the 56 randomized subjects enrolled in the study across seven cohorts, 42 subjects were treated with PRX-115 and 14 subjects were treated with a placebo.

After a review of the initial positive top-line results from the seven cohorts, and following the review and acceptance of the safety data from cohort 7 by the safety and monitoring committee for dose escalation for the FIH Study, the Company decided to expand the study by adding an eighth cohort of eight new subjects to analyze a higher dose and its potential to result in increased exposure time. In addition to the expansion of the FIH Study, the Company also decided to commence preparations for a phase II clinical trial of PRX-115.

Key preliminary results from the FIH Study are as follows:

●Exposure to PRX-115 increased in a dose-dependent manner.

●PRX-115 rapidly reduced plasma uric acid concentrations to below 6.0 mg/dL over time following a single administration. The effect of PRX-115 on plasma uric acid concentrations and the duration of response was found to be dose dependent.

●PRX-115 was well-tolerated. Twenty-six percent (11/42) of the subjects treated with PRX-115 in the first seven cohorts reported study drug-related adverse events (AEs), the majority being mild to moderate and transient in nature. One subject in cohort 2 experienced an anaphylactic reaction immediately following the commencement of the infusion, and the reaction was fully resolved. There were no other serious AEs reported in the study, and no AEs were reported in the highest doses, cohorts 6 and 7.

Research & Development

In addition, to PRX-115 and PRX-119, the Company’s plant cell-expressed PEGylated recombinant human DNase I product candidate being designed to elongate half-life in the circulation for NETs-related diseases, the Company is focusing its research & development efforts on early-stage development assets to build its product development pipeline.

First Quarter 2024 Financial Highlights

●The Company recorded revenues from selling goods of $3.7 million for the three months ended March 31, 2024, a decrease of $1.4 million, or 27%, compared to revenues of $5.1 million for the three months ended March 31, 2023. The decrease resulted primarily from a decrease of $1.1 million in sales to Pfizer, and of $0.3 million in sales to Brazil. The decreases resulted primarily from the timing of delivery.

●The Company recorded revenues from license and R&D services of $0.1 million for the three months ended March 31, 2024, a decrease of $4.4 million, or 98%, compared to revenues of $4.5 million for the three months ended March 31, 2023. Revenues from license and R&D services are comprised primarily of revenues we recognized in connection with the Chiesi Agreements. The decrease resulted primarily from the completion of the Company’s research and development obligations with respect to Elfabrio and, as Elfabrio was approved in the United States and the European Union in May 2023, from the completion of the regulatory processes related to the review of the BLA and the MAA for Elfabrio by the FDA and EMA, respectively.

●Cost of goods sold was $2.6 million for the three months ended March 31, 2024, a decrease of $0.5 million, or 16%, from cost of goods sold of $3.1 million for the three months ended March 31, 2023. The decrease in cost of goods sold was primarily the result of the decrease in sales to Pfizer and to Brazil.

●For the three months ended March 31, 2024, the Company’s total research and development expenses were approximately $2.9 million, comprised of approximately $0.5 million in subcontractor-related expenses, approximately $1.5 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 March 31, 2023, the Company’s total research and development expenses were approximately $5.8 million comprised of approximately $3.5 million of subcontractor-related expenses, approximately $1.5 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 March 31, 2024 was $2.9 million, or 50%, compared to the

three months ended March 31, 2023. The decrease in research and development expenses primarily resulted from the completion of the Company’s Fabry clinical program and the regulatory processes related to the BLA and MAA review of Elfabrio by the applicable regulatory agencies.

●Selling, general and administrative expenses were $3.1 million for the three months ended March 31, 2024 and for the three months ended March 31, 2023.

●Financial income, net were $0.1 million for the three months ended March 31, 2024, compared to financial expenses, net of $0.5 million for the three months ended March 31, 2023. The change resulted primarily from higher interest income on bank deposits and lower notes interest expenses due to note conversions executed in 2023.

●In the three months ended March 31, 2024, the Company recorded a tax benefit of approximately $(0.1) million, compared to income taxes of $0.2 million for the three months ended March 31, 2023. Income taxes recorded are primarily from the provision for current taxes on income mainly derived from U.S. taxable global intangible low-taxed income (GILTI) mainly in respect of Section 174 of the U.S. Tax Cuts and Jobs Act.

●Cash, cash equivalents and short-term bank deposits were approximately $48.5 million at March 31, 2024.

●Net loss for the three months ended March 31, 2024 was approximately $4.6 million, or $0.06 per share, basic and diluted, compared to a net loss of $3.1 million, or $0.05 per share, basic and diluted, for the same period in 2023.
