Stealth (MITO) Files NDA for Ultra-Rare Disease Candidate

Read MoreHide Full Article

Stealth BioTherapeutics Corp announced that it has submitted a new drug application (“NDA”) to the FDA, seeking approval for its lead pipeline candidate, elamipretide, for the treatment of Barth syndrome, an ultra-rare genetic condition characterized by a weakened heart. Currently, there is no treatment approved for the given indication.

The NDA was based on data from the phase III SPIBA-001 retrospective natural history control study, which compared data from the open-label portion of the phase II/III TAZPOWER study to matched natural history controls.

The SPIBA-001 study met the primary and most secondary endpoints by showing elamipretide-mediated improvements in assessments of exercise tolerance, strength and cardiac function.

Data from the TAZPOWER study also demonstrated improvements in several surrogate and intermediate clinical endpoints that may likely predict the clinical benefits for patients suffering this debilitating disease. This data might likely support an accelerated approval pathway for elamipretide.

Shares of Stealth BioTherapeutics have plunged 20.4% so far this year against the industry’s growth of 1.2%.

We remind investors that the FDA has already granted a rare pediatric designation, fast track designation and an orphan drug designation to elamipretide for treating Barth syndrome. The European Medicines Agency has also granted an orphan drug designation to elamipretide for the given indication.

Apart from Barth syndrome, elamipretide is also being evaluated in mid- to late-stage studies for treating several other diseases like Geographic atrophy, mitochondrial diseases entailing nuclear DNA mutations, Duchenne muscular dystrophy and Friedreich's ataxia.

Stealth BioTherapeutics has no approved product in its portfolio at the moment. Therefore, pipeline development remains a key focus for the company. If successfully developed and upon potential approval, elamipretide will be a boost to the company’s growth prospects, as it will be able to generate revenues.
