A Randomized, Double-blind, Placebo-controlled Study of SRP-9001 for Duchenne Muscular Dystrophy (DMD)

key information

study id #: NCT03769116

condition: Muscular Dystrophy, Duchenne

status: recruiting


The purpose of this study is to evaluate the safety and efficacy of exogenous gene transfer in DMD patients by measuring biological and clinical endpoints in two parts: a 48-week randomized, double-blinded, placebo-controlled period (Part 1), and a 96-week, double-blinded extension period (Part 2).

intervention: SRP-9001, Placebo

mechanism of action: Gene therapy to introduce a version of dystrophin

results: https://clinicaltrials.gov/ct2/show/results/NCT03769116

last updated: October 21, 2019
