A trial for boys with a muscle disease will track muscle fat on scans, not strength tests
Satellos Bioscience (NASDAQ: MSLE, TSX: MSCL) has updated its Phase 2 BASECAMP trial for Duchenne muscular dystrophy (DMD) to use MRI-measured fat fraction as the primary endpoint, replacing strength tests. The change follows FDA feedback and aims to support a potential accelerated approval pathway for forazapadin. Topline data is expected in Q1 2027. The company held a conference call to discuss the trial on Nov. 6, 2026.
