About stealth

We are a clinical-stage biotechnology company focused on the discovery, development and commercialization of novel therapies for diseases involving mitochondrial dysfunction. Mitochondria, found in almost every cell in the body, are the body’s main source of energy production and are essential for normal organ function. Dysfunctional mitochondria characterize a number of rare genetic diseases and are implicated in many common age-related diseases, typically involving energy-intensive organ systems such as the heart, eyes, and brain. We believe that our lead product candidate, elamipretid, has the potential to treat both rare metabolic cardiomyopathies, such as Barth’s muscular dystrophy, Duchenne’s muscular dystrophy, and Friedreich’s ataxia, rare mitochondrial diseases resulting in mutations of nuclear DNA, as well as ophthalmic diseases resulting in mitochondrial dysfunction, such as dry age-related macular degeneration and Leber’s hereditary optic neuropathy. We are evaluating our second generation clinical stage candidate, SBT-272, and our new small molecule series, SBT-550, for indications of rare neurological diseases following promising preclinical data. We have optimized our discovery platform to identify novel mitochondria-targeted compounds that can be named as therapeutic product candidates or used as mitochondria-targeted vectors to deliver other compounds to mitochondria.
