Introduction • Taliglucerase alfa is an enzyme replacement therapy (ERT) approved for treatment of adults with Type 1 Gaucher disease (GD) and is the first approved plant cell–expressed recombinant therapeutic protein.1,2 • The safety and efficacy of taliglucerase alfa 30 U/kg and 60 U/kg were demon
Slide 5: Study Design
Study Design • Phase 3, multicenter, double-blind, randomized trial (PB-06-003; NCT00705939) of taliglucerase alfa at 2 dose levels • Dosing: 30-U/kg or 60-U/kg intravenous (IV) infusion every other week • Efficacy assessments – Spleen volume, liver volume, platelet count, hemoglobin concentration,
