Clinical Trial Summary

A long-term follow-up study to evaluate the safety, tolerability, and efficacy of DTX101 in adult males with moderate/severe to severe hemophilia B.


Clinical Trial Description

Hemophilia B is an X-linked recessive genetic bleeding disorder caused by mutations in the factor IX (FIX) gene. FIX is produced in the liver and is critical for fibrin clot formation. Hemophilia B is characterized by frequent, spontaneous internal bleeding that can lead to chronic arthropathy (joint damage), intracranial hemorrhage, and even death. In patients with moderate/severe to severe hemophilia B, the majority of bleeding episodes occur in the joints and, if not treated, lead to debilitating damage and a decreased quality of life. Study 101HEMB02 is a long-term follow-up study to evaluate the safety, tolerability, and efficacy of AAVrh10-mediated gene therapy of human FIX in subjects with moderate/severe to severe hemophilia B. The primary objective of the study is to determine the long-term safety and efficacy of DTX101 following a single IV infusion (administered during Study 101HEMB01) in adults with moderate/severe to severe hemophilia B. This study was previously posted by Dimension Therapeutics, which has been acquired by Ultragenyx. ;
