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 for marketing 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.

Pegunigalsidase alfa, Protalix's main investigational new drug product, is a modified version of the recombinant human -Galactosidase-A protein for the proposed treatment of Fabry disease. The FDA has accepted a Biologics License Application (BLA), and granted Priority Review designation, for pegunigalsidase alfa for the proposed treatment of adult patients with Fabry disease. The BLA was submitted via the FDA's Accelerated Approval pathway. 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.

In addition, Protalix's development pipeline consists of other proprietary versions of recombinant therapeutic proteins that target established pharmaceutical markets.
