PARMA, Italy, July 25, 2018 -- Chiesi, an international research-focused healthcare Group, today announced the expansion of its partnership with Protalix BioTherapeutics, Inc. (NYSE American:PLX, TASE:PLX), a biopharmaceutical company focused on the development and commercialization of recombinant therapeutic proteins expressed through its proprietary plant cell-based expression system, ProCellEx®. Protalix and Chiesi entered into an exclusive U.S. license and supply agreement which grants to Chiesi the United States rights for the development and commercialization of PRX-102 (pegunigalsidase alfa), the Company’s chemically modified version of the recombinant protein alpha-Galactosidase-A protein, for the treatment of Fabry disease. In October 2017, Protalix announced an exclusive partnership with Chiesi for the development and commercialization of PRX-102 for the treatment of Fabry disease outside the United States.
Under the terms of the U.S. license and supply agreement, Protalix is entitled to an upfront payment of $25 million from Chiesi and additional payments of up to a maximum of $20 million in development costs, capped at $7.5 million per year. Protalix is also eligible to receive additional amounts in regulatory and commercial milestone payments, and tiered double-digit payments based on Chiesi net sales as consideration for product supply. Protalix will continue to be the manufacturer of PRX-102 for clinical development and commercial purposes.
“We are very pleased to expand our collaboration with Chiesi, a growing global company with well-established global commercial infrastructure with a fast-growing commercial presence in the U.S. Chiesi’s global investment of $95 million in upfront payments and development costs reimbursement, and the additional milestone payments, combined in the two agreements reflects Chiesi’s true commitment to the Fabry space,” commented Moshe Manor, Protalix’s President and Chief Executive Officer.
“We believe PRX-102 has the potential to transform the treatment of Fabry disease and are excited to now have exclusive commercial rights to PRX-102 worldwide,” said Ugo Di Francesco, Chiesi’s Chief Executive Officer. “The more we work with Protalix and see the progress made in the development and the product’s characteristics, it becomes abundantly clear the significant role PRX 102 could have in the underserved Fabry market and to potentially change the treatment paradigm to the benefit of all stakeholders. We believe this U.S. license agreement will bring many synergies in our fast-growing U.S. presence in rare diseases.”
Additional details regarding the collaboration can be found in Protalix's Form 8-K to be filed with the Securities and Exchange Commission.
