Objective

EDG-5506-203 MESA is an open-label extension study to assess the long-term effect of sevasemten (EDG-5506) on safety, biomarkers, and functional measures in adults and adolescents with Becker muscular dystrophy

Description

This is an open-label, treatment extension study to evaluate the safety, tolerability, and durability of effect in long-term dosing of sevasemten. EDG-5506-203 MESA will provide continued access to sevasemten treatment to participants with Becker muscular dystrophy who were previously enrolled in EDG-5506-002 ARCH, completed EDG-5506-201 CANYON and GRAND CANYON, or completed EDG-5506-202 DUNE.
