Pfizer/Protalix’s Elelyso Offers Gaucher Patients A Vegetarian Option

Gaucher disease enzyme-replacement therapy Elelyso is the first FDA-approved plant-cell based recombinant therapeutic protein, a biosimilar option that may eliminate the production-related problems Genzyme’s Cerezyme and Shire’s Vpriv face with animal cell-based processes. Pfizer is launching Elelyso at a 25% discount to Cerezyme and promising to maintain a two-year supply.
