Brief summary
The GalaxyDMD study is a global Phase 3, open-label, treatment extension study to evaluate the safety, tolerability, and durability of effect in long-term dosing of edasalonexent in pediatric patients with a genetically confirmed diagnosis of DMD. Patients who completed CAT-1004-201 or CAT-1004-301 or siblings of these boys from 4-12 years of age (up to 13th birthday) will be enrolled. Edasalonexent is an orally administered small molecule that inhibits NF-kB, which is a 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.
Detailed description
The study includes a 104-week open-label treatment period with edasalonexent. Patients who completed CAT-1004-201 or CAT-1004-301 and eligible siblings of these boys will be enrolled in this trial.
