Elamipretide

Elamipretide (also known as SS-31, , MTP-131 and Bendavia)[1][2] is a small mitochondrially-targeted tetrapeptide (D-Arg-dimethylTyr-Lys-Phe-NH2) that appears to reduce the production of toxic reactive oxygen species and stabilize cardiolipin.[3]

Stealth Peptides, a privately held company, was founded in 2006 to develop intellectual property licensed from several universities including elamipretide; it subsequently changed its name to Stealth BioTherapeutics.[4][5]

As of November 2017 Stealth had obtained an orphan designation in the US for use in mitochondrial myopathy and had started a Phase III trial in that indication.[2] As of January 2020, trial expectations were not met.[6]
