Long-term Safety and Efficacy of Odevixibat in Patients With Alagille Syndrome

Running, not enrolling · Phase 3

Conditions studied: Alagille Syndrome

In brief

The purpose of this study is to assess the long-term safety and effectiveness of odevixibat in participants with Alagille syndrome (ALGS). The participants of this study will have ALGS a rare genetic disorder that can affect multiple organ systems of the body including the liver, heart, skeleton, eyes and kidneys. Common symptoms, which often develop during the first three months of life, include blockage of the flow of bile from the liver (cholestasis), yellowing of the skin and mucous membranes (jaundice), poor weight gain and growth and severe itching (pruritis). The drug used for the study is odevixibat and was authorized for the treatment of cholestatic pruritus in infants with ALGS over 12 months of age by the United States Food and Drug Administration on 13 June 2023.
