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.\n\nStudy 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.\n\nThis study was previously posted by Dimension Therapeutics, which has been acquired by Ultragenyx.'}, 'eligibilityModule': {'sex': 'MALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Adult males with moderate/severe to severe Hemophilia B previously enrolled in 101HEMB01 clinical study', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
