Recruitment Status : Terminated (The Phase 3 PolarisDMD trial did not meet the primary endpoint. As a result, activities related to the development of edasalonexent have stopped including the CAT-1004-302 Open-Label Study of Edasalonexent in Boys With Duchenne Muscular Dystrophy)

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.

Experimental: Dose 1
Edasalonexent 100mg/kg/day. Capsules taken by mouth three times per day.
- Safety and tolerability of long-term treatment with edasalonexent measured by number of treatment-emergent adverse events (TEAEs) and serious adverse events (SAEs) [ Time Frame: 104 Weeks ]
- Durability of effects of edasalonexent on physical function as measured by the North Star Ambulatory Assessment (NSAA) [ Time Frame: 104 Weeks ]
- Durability of effects of edasalonexent on physical function as measured by the 10-meter walk/run test [ Time Frame: 104 Weeks ]
- Durability of effects of edasalonexent on physical function as measured by the time to stand from supine [ Time Frame: 104 Weeks ]
- Durability of effects of edasalonexent on physical function as measured by the 4-stair climb [ Time Frame: 104 Weeks ]
