SS-31
Also known as: Elamipretide
SS-31 (elamipretide) is a mitochondria-targeted tetrapeptide (D-Arg-Dmt-Lys-Phe-NH2) developed by Hazel Szeto (Cornell) and clinically advanced by Stealth BioTherapeutics. It concentrates in the inner mitochondrial membrane by binding cardiolipin. In September 2025, the FDA granted accelerated approval to elamipretide (brand name FORZINITY) as the first therapy for Barth syndrome — the first FDA-approved mitochondria-targeted drug. It remains investigational for other indications.
