FDA Advisory Committee Supports Elamipretide for Ultra-Rare Barth Syndrome Amid Data Challenges
The FDA Advisory Committee voted 10-6 in favor of elamipretide, a therapy developed by Stealth BioTherapeutics for the ultra-rare Barth syndrome, despite significant challenges in the data presented[1][2]. The committee recognized the urgent need for treatment options, even though the efficacy data from the trials did not meet statistical significance and were subject to variability[1][2]. Several members, including Carole Tucker, emphasized positive trends and patient testimonies as key in their decision to support the therapy[1]. However, the FDA remains skeptical about the drug's approvability due to concerns over trial results, with a final decision expected by January 29, 2025[2].
