Positive vote from FDA Advisory Committee meeting supporting potential approval of elamipretide for the treatment of Barth syndrome

The CRDAC discussed the benefits and risks of elamipretide for the treatment of Barth syndrome, including results from the TAZPOWER Part 2 baseline-controlled extension study, the SPIBA-001 Phase III natural history control study, and additional supportive biomarker and preclinical data. The CRDAC’s vote, while not binding, will be considered by the FDA when making its decision regarding the potential approval of elamipretide for Barth syndrome. If approved, elamipretide would be the first therapy for this ultra-rare, progressive, life-shortening, cardioskeletal disease that affects approximately 150 individuals in the United States. The NDA for elamipretide was granted priority review and has been assigned a Prescription Drug User Fee Act (“PDUFA”) action date of January 29, 2025.

If approved, this would be the first marketing authorization for elamipretide, a first-in-class mitochondria-targeted therapeutic. In addition to Barth syndrome, elamipretide is in Phase 3 trials for primary mitochondrial myopathy, with pivotal data expected by the end of 2024, and for dry age-related macular degeneration.

About Barth Syndrome; Barth syndrome is an ultra-rare genetic condition characterized by cardiac abnormalities leading to exercise intolerance, muscle weakness, debilitating fatigue, heart failure, recurrent infections, and delayed growth. The disease is associated with reduced life expectancy, with 85% of early deaths occurring by age 5. Barth syndrome occurs primarily in males and is estimated to affect one in 1,000,000 males worldwide or around 150 individuals in the United States. There are currently no FDA- or EMA-approved therapies for patients with Barth syndrome. Elamipretide has Orphan Drug, Fast Track and Rare Pediatric Designation from the FDA and Orphan Drug Designation from the EMA for the treatment of Barth syndrome.
