Enrolled participants in this study will receive a single oral dose or multiple oral doses of EDG-5506 or a placebo. Blood and urine samples will be collected to measure how EDG-5506 is processed by the body and how the body responds when exposed to EDG-5506. Participants in the single ascending dose part of the study will remain in the clinic for 7 days with a 42-day follow-up period. Participants in the multiple ascending dose part of the study will remain in the clinic for 16 days with a 13-day follow-up period. Safety, tolerability, and pharmacokinetics of EDG-5506 will be assessed in healthy volunteers prior to enrolling participants with Becker muscular dystrophy.
EDG-5506 is an investigational product intended to protect and improve function of dystrophic muscle fibers. This Phase 1 study of EDG-5506 will assess the safety, tolerability, and pharmacokinetics (PK) and of EDG-5506 in adult healthy volunteers and in adults with Becker muscular dystrophy (BMD).
