Primary Mitochondrial Myopathy Drug Fast Tracked by FDA

Elamipretide treats rare genetic disorder that causes muscle weakness and severe fatigue.

The FDA has granted Fast Track designation for a drug candidate designed to help patients suffering from primary mitochondrial myopathy.

Stealth BioTherapeutics developed the drug elamipretide, formerly known as Bendavia, in hopes to treat this rare genetic disorder that impairs health with muscle weakness and severe fatigue. Currently there are no FDA approved medications.

Researchers from the Institut de recherches cliniques de Montréal (IRCM) discovered a family of molecules, elamipretide being among them.

“Elamipretide targets the inner mitochondrial membrane and helps preserve mitochondrial energetics,” said drug discoverer Peter W. Schiller, PhD. “Due to this property, elamipretide could become the first treatment designed for primary mitochondrial myopathy. The FDA’s grant of a Fast Track designation for this treatment is therefore excellent news.”

The FDA’s Fast Track program increases the likelihood for eligibility of priority review and accelerated approval if certain criteria is met for these drugs that treat serious conditions.
