Immune Thrombocytopenia Clinical Trial
Official title:
A Multicenter, Open-Label Study to Evaluate the Safety and Efficacy of Avatrombopag and Remission Rates in Adults With Immune Thrombocytopenia (ITP) of ≤6 Months Duration
This study will evaluate the safety and efficacy of avatrombopag in subjects with a confirmed diagnosis of primary ITP (≤6 months duration) over 26 weeks of treatment, and also evaluate the incidence of ITP remission.
This phase 3b, multi-center, open-label study will enroll approximately 75 adult subjects with a confirmed diagnoses of primary ITP (≤6 months duration) who have had a previous response to a first line treatment. The study will consist of a 26-week treatment period to evaluate the safety and efficacy of avatrombopag. Subjects with platelet counts ≥50×10⁹/L at Week 26 may enter a dose-tapering period in which the dose of avatrombopag will be decreased for up to 16 weeks until avatrombopag treatment is discontinued and the platelet count is maintained ≥50×10⁹/L. Once avatrombopag treatment has been discontinued, the subjects will enter a remission evaluation period of up to 24 weeks to evaluate whether they have entered a state of remission. ;
