Official Title

BCX9930 for Treatment of PNH in Subjects With Inadequate Response to C5 Inhibitor Therapy (REDEEM-1 Trial)

Purpose

The purpose of this study is to evaluate the efficacy and safety of BCX9930 as a treatment for PNH in adult patients with ongoing anemia despite treatment with a C5 inhibitor (either eculizumab or ravulizumab). BCX9930 is a Factor D inhibitor administered orally (by mouth). The study will recruit approximately 81 patients worldwide and each individual’s participation will last approximately 1 year. The study will be run in two parts. In part 1, participants will be randomly assigned in a 2:1 ratio to either (a) stop their C5 inhibitor and start oral BCX9930 or (b) remain on the C5 inhibitor for 24 weeks. In part 2, all participants will receive BCX9930. Participants assigned to continue their C5 inhibitor initially will stop treatment after Week 24 and switch to BCX9930. Patients assigned to BCX9930 initially will continue BCX9930 in part 2. At the end of the study (Week 52), participants who are experiencing benefit from BCX9930 treatment may be allowed to continue BCX9930 treatment in a long-term follow-up study.
