Clinical Scientist (LN19-198)

Catalyst is a clinical-stage biopharmaceutical company focused on developing novel treatments for hemophilia and other rare bleeding disorders using our potent, subcutaneous (SQ) coagulation factors that promote prophylaxis therapy. We have completed the Phase 2 trial of our subcutaneous (SQ) Factor VIIa (FVIIa) variant marzeptacog alfa (activated) (MarzAA) for prophylaxis. The study met the primary endpoint of significantly reducing the annualize bleed rate (ABR) in patients with hemophilia A or B with inhibitors.  The study also met all secondary endpoints of safety, tolerability and lack of anti-drug antibody or inhibitor formation.  We have also initiated enrollment in a Phase 2b trial of dalcinonacog alfa – DalcA, a next-generation (SQ) administered Factor IX (FIX) therapy being developed for the treatment of hemophilia B.
