Protalix Biotherapeutics Inc (PLX) Shares Skyrocket – Here’s Why


It’s a very rewarding trading day for investors in Protalix Biotherapeutics Inc (NYSEAMERICAN:PLX) with shares up over 35%, making the stock Wall Street’s bull of the day. The reason? The Israeli drug maker said it has entered into Ex-US license and collaboration agreement with Chiesi Farmaceutici S.p.A., or Chiesi, for pegunigalsidase alfa, or PRX-102, the Company’s chemically modified version of the recombinant protein alpha-Galactosidase-A protein that is currently being evaluated in phase III clinical trials for the treatment of Fabry disease.

Under the terms of the agreement, Protalix has licensed PRX-102 to Chiesi for all markets outside of the United States, and Protalix will receive an upfront payment of $25 million from Chiesi and additional payments of up to $25 million in development costs, capped at $10 million per year.  Protalix is also eligible to receive an additional up to $320 million, in the aggregate, in regulatory and commercial milestone payments, and tiered royalties ranging from 15% to 35% on net sales. Protalix will continue to be the manufacturer of PRX-102 for clinical development purposes and commercial purposes after marketing approvals.

Protalix’s CEO Moshe Manor commented, “We are pleased to partner with Chiesi, an international privately-held company with more than 80 years of experience and a strong focus on the development and commercialization of innovative medicines with commercial presence in virtually all markets outside the United States […] The $50 million commitment made by Chiesi before any of our ongoing phase III clinical trial results read-out is not only a significant non-dilutive cash infusion for us, it also represents Chiesi’s commitment to the Fabry market in general and our PRX-102 program in particular.  With this transaction, we have secured significant and important funding while maintaining full rights to PRX-102 in the U.S. market.”

Chiesi’s CEO Ugo Di Francesco stated, “With revenues of approximately $1.8 billion, the Chiesi Group is among the top 50 pharmaceutical companies in the world.  By combining the respective strengths of Chiesi and Protalix to advance PRX-102, we look forward to bringing a novel, differentiated therapeutic option to patients suffering from Fabry disease who have a true need for an alternative treatment with an improved safety and efficacy profile […] PRX-102 complements our existing product portfolio in rare diseases and underscores our commitment to bringing novel therapeutics to patients across the globe.”
