Stealth eligible for rare pediatric disease priority review voucher
BOSTON, March 3, 2020 /PRNewswire/ -- Stealth BioTherapeutics (NASDAQ: MITO), a clinical-stage biotechnology company focused on the discovery, development and commercialization of novel therapies for diseases involving mitochondrial dysfunction, today announced that the U.S. Food and Drug Administration (FDA) has granted Rare Pediatric Disease (RPD) designation for elamipretide for the treatment of Barth syndrome, an ultra-rare genetic condition.
Under the FDA's RPD designation program, the FDA may grant a priority review voucher to a sponsor who receives approval for a "rare pediatric disease," a serious and life-threatening disease that primarily affects individuals aged from birth to 18 years and fewer than 200,000 people in the United States. Upon FDA approval of elamipretide for Barth syndrome, Stealth BioTherapeutics is eligible for a voucher that can be used to obtain priority review for a subsequent human drug application upon meeting relevant statutory requirements associated with the RPD program.
"This designation for elamipretide underscores our alignment with the FDA around the significant and urgent unmet medical need for Barth patients," said Reenie McCarthy, Chief Executive Officer of Stealth. "We hope to improve the healthspan of Barth patients, for whom cardiomyopathy, exercise intolerance and debilitating fatigue limit life expectancy and impair quality of life. We are also expanding our development efforts to consider trials in patients suffering from overlapping metabolic cardiomyopathies in diseases such as Duchenne and Becker muscular dystrophies, and Friedreich's ataxia."
About Barth Syndrome
Barth syndrome is an ultra-rare genetic condition characterized by cardiac abnormalities often leading to heart failure and reduced life expectancy, recurrent infections, muscle weakness and delayed growth. Barth syndrome occurs almost exclusively in males and is estimated to affect one in 200,000 to 400,000 individuals worldwide. There are currently no FDA- or EMA-approved therapies for patients with Barth syndrome.
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 nearly every cell in the body, are the body's main source of energy production and are critical for normal organ function. Dysfunctional mitochondria characterize a number of rare genetic diseases and are also involved in many common age-related diseases, typically involving organ systems with high energy demands such as the heart, the eye, and the brain. We believe our lead product candidate, elamipretide, has the potential to treat both rare metabolic cardiomyopathies, such as Barth, Duchenne and Becker muscular dystrophies, and Friedreich's ataxia, as well as ophthalmic diseases entailing 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, for rare neurodegenerative disease indications following promising preclinical data in amyotrophic lateral sclerosis, or ALS. Our pipeline compounds include SBT-259, which we are evaluating for rare peripheral neuropathies, and the SBT-550 series of compounds, which we plan to evaluate for rare neurodegenerative and ophthalmic indications. We have optimized our discovery platform to identify novel mitochondria-targeted compounds, which may be nominated as therapeutic product candidates or utilized as scaffolds to deliver other compounds to mitochondria. We have assembled a highly experienced management team, board of directors and group of scientific advisors to help us achieve our mission of leading mitochondrial medicine.
