Official title
A Phase 1 Safety Study in Subjects With Severe Hemophilia B (Factor IX Deficiency) Using a Single-Stranded, Adeno-Associated Pseudotype 8 Viral Vector to Deliver the Gene for Human Factor IX
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Hemophilia B is a bleeding disease in males due to very low levels of coagulation factor IX (FIX) in the blood. The current treatment is intravenous injection of FIX clotting factor concentrates, in response to bleeding. This study will focus on the severe, most common type of hemophilia B. This study plans to use a virus called adeno-associated virus (AAV), which in nature causes no disease, and can be engineered to deliver the human FIX gene (AAV8-hFIX19 vector) to liver cells, where FIX is normally made. This study will use the AAV8-hFIX19 vector.
