Brief Summary:

The PolarisDMD study is a Phase 3, global study to evaluate the efficacy and safety of edasalonexent in pediatric patients with a genetically confirmed diagnosis of DMD. Male patients from 4-7 years of age (up to 8th birthday) will be enrolled.

Edasalonexent is an orally administered small molecule that inhibits NF-kB, which is the key link between loss of dystrophin and disease pathology and plays a fundamental role in the initiation and progression of skeletal and cardiac muscle disease in DMD.

Condition or disease Intervention/treatment Phase
Muscular Dystrophy, Duchenne Drug: Edasalonexent Drug: Placebo Phase 3

Detailed Description:

The study includes a 52-week, randomized, double-blind, placebo-controlled period, followed by a 2-week follow- up. Approximately 125 boys with DMD will be enrolled in this trial, with 2 boys receiving edasalonexent for every 1 boy receiving placebo.

Following completion of the treatment period, patients may elect to continue in a separate open-label extension study.
