A Pilot Study Evaluating the Safety, Tolerability and Efficacy of Gene Therapy With BBM-H901 in Hemophilia B Patients Aged 12-18 Years Old

Study Summary

This is a Phase 1, open- label, non- randomized, uncontrolled, single dose pilot study to evaluate the safety, tolerability and efficacy of a single intravenous infusion of BBM-H901 in hemophilia B subjects with ≤2IU/dl residual FIX levels and aged 12-18 years old. BBM-H901 is an adeno-associated viral (AAV) vector designed to drive expression of the human factor IX (hFIX) transgene and raise circulating levels of endogenous FIX.
