CARMIEL, Israel, Aug. 15, 2022 /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, 2022 and provided a business update on recent corporate and regulatory developments.

"Positive topline results from our phase III BALANCE clinical trial of PRX-102 for the treatment of adult patients with Fabry disease were announced last April. The clinical study report (CSR) for the trial is now complete," said Dror Bashan, Protalix's President and Chief Executive Officer. "The final analysis of the BALANCE study, which was designed to evaluate the efficacy and safety of 1 mg/kg of PRX–102 administered every other week compared to agalsidase beta in patients previously treated with agalsidase beta, confirms the positive topline results and favorable tolerability profile. The results from the BALANCE study highlight our confidence that PRX–102 has the potential to become an important treatment option for patients with Fabry disease. We are excited to move closer to potential approval of PRX–102 and commercial launch, and thank our team members and external partners for their continued support."

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 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 stabilized version of the recombinant human α–Galactosidase–A protein for the treatment of Fabry disease; alidornase alfa or PRX–110, for the treatment of various human respiratory diseases or conditions; PRX–115, a plant cell-expressed recombinant PEGylated uricase for the treatment of severe gout; PRX–119, a plant cell-expressed long action DNase I for the treatment of NETs-related diseases; 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.
