Stealth BioTherapeutics Receives Orphan Drug Designation from the European Medicines Agency for Elamipretide for the Treatment of Myopathic Mitochondrial DNA Depletion Syndrome
|
Orphan drug designation applies to patients with primary mitochondrial myopathy due to nuclear DNA mutations (nPMM) in the NuPower Phase 3 clinical trial NuPOWER Phase 3 trial is currently enrolling patients with multiple clinical trial sites initiated in the United States and Europe BOSTON, May 31, 2022 /PRNewswire/ -- Stealth Biotherapeutics Corp (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 European Medicines Agency (EMA) has granted orphan drug designation (ODD) for elamipretide for the treatment of myopathic mitochondrial DNA depletion syndrome (M-MDS), a designation which applies to patients with nPMM eligible for enrollment in the NuPOWER Phase 3 clinical trial, which is currently enrolling patients at multiple clinical trial sites in the United States and Europe.
"We are pleased that EMA has recognized the high unmet need for innovative treatments for this rare genetic condition which significantly limits the quality of life of affected individuals," said Chief Executive Officer Reenie McCarthy. "Orphan drug designation for M-MDS marks an important step toward advancing our regulatory initiatives in Europe. As we continue to enroll patients in this pivotal trial, this designation strengthens our ability to support partnership opportunities in the European markets" ODD is granted to investigational therapies intended for the safe and effective treatment of rare diseases with an unmet medical need that affect fewer than 5 in 10,000 people in the European Union. This designation provides companies with certain benefits and incentives including clinical protocol assistance, differentiated evaluation procedures for Health Technology Assessments in certain countries, access to a centralized marketing authorization procedure valid in all EU Member States, and if approved, marketing exclusivity in the EU for 10 years. About M-MDS and nPMM M-MDS is caused by mutations in nuclear DNA genes encoding for enzymes responsible for maintenance and replication of mitochondrial DNA. Mitochondrial DNA replication, which is critical to support muscular energy demands, can be impaired as a result of these mutations, leading to signs and symptoms of M-MDS. M-MDS is characterized by muscle weakness, exercise intolerance, peripheral neuropathy and, in some cases, progressive external ophthalmoplegia. These patients are also considered to have primary mitochondrial myopathy, or PMM, for which the Company has previously received orphan drug designation from the US FDA. There are currently no FDA- or EMA-approved therapies for patients with M-MDS. 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 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 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 muscular dystrophy and Friedreich's ataxia, rare mitochondrial diseases entailing nuclear DNA mutations, as well as ophthalmic diseases entailing mitochondrial dysfunction, such as dry age-related macular degeneration. We are evaluating our second-generation clinical-stage candidate, SBT-272, and our new series of small molecules, SBT-550, for rare neurological disease indications following promising preclinical data. We have optimized our discovery platform to identify novel mitochondria-targeted compounds which may be nominated as therapeutic product candidates or utilized as mitochondria-targeted vectors to deliver other compounds to mitochondria.
