Clinical Trial 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.


Clinical Trial Description

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. Nine subjects will be enrolled and administered with single infusion of BBM-H901, an AAV at one dose level of 5x10'12 vg/Kg. Subjects and statutory guardian must provide informed consent and then undergo screening assessments up to 4-8weeks prior administration of BBM-H901. All subjects will undergo 52(+- 2) weeks safety observation and will be continuously followed up to evaluate long- term safety and efficacy of BBM-H901 up to ten years. The first subject will be dosed at 5x10'12 vg/Kg and undergo 8 weeks safety observation of which the data will undergo review by an independent safety committee. ;
