Summary

This phase 2 trial tests a daily oral drug called sevasemten (EDG-5506) in 244 adults and adolescents with Becker muscular dystrophy, a condition that causes progressive muscle weakness. The study compares the drug to a placebo to see if it can reduce muscle damage, improve walking ability, and be safe. Participants take the drug once daily for several months, and researchers track changes in muscle enzymes and physical function.
