Straight A’s for MarzAA

Last month at the 2019 Congress of the International Society on Thrombosis and Haemostasis (ISTH), Catalyst Biosciences Inc. presented Phase 2 data regarding its subcutaneous (SQ) Factor VIIa (FVIIa) variant marzeptacog alfa (activated) (MarzAA) for prophylaxis in patients with hemophilia A or B with inhibitors. The study met its primary endpoint of significantly reducing the annualized bleed rate, as well as all secondary endpoints of safety, tolerability and lack of anti-drug antibody or inhibitor formation.
