This systematic review and meta-analysis evaluated five randomized controlled trials (RCTs) on exon-skipping therapies for Duchenne muscular dystrophy (DMD). Analyzing 322 patients, the study assessed eteplirsen and drisapersen using 6MWT and NSAA scores. Results showed no significant improvement over placebo. Drisapersen (6 mg/kg) provided minor benefits but had renal toxicity risks, while eteplirsen showed fewer side effects but lacked robust efficacy data. The study calls for long-term trials to confirm exon skipping’s clinical impact.
