Stealth BioTherapeutics Corp (Nasdaq: MITO) announced the selection of two abstracts for virtual presentation at the 13th International Conference on Cachexia, Sarcopenia, and Wasting Diseases from December 11-13, 2020. The presentations will showcase positive findings from elamipretide trials, particularly the MMPOWER-3 trial, which demonstrated improvements in the six-minute walk test for patients with mtDNA replisome disorders. The TAZPOWER study highlighted progress in key biomarkers related to mitochondrial dysfunction, which may impact treatment approaches for muscle wasting and cardiomyopathies.

Positive
  • Positive results from the MMPOWER-3 trial indicating improved six-minute walk test performance.
  • Encouraging biomarker improvements in the TAZPOWER study for treating mitochondrial dysfunction.
Negative
  • None.

BOSTON, Dec. 9, 2020 /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 two abstracts have been selected for virtual presentations including a poster presentation and a late breaking research oral presentation at the upcoming 13th International Conference on Cachexia, Sarcopenia and Wasting Diseases being held online from December 11-13, 2020. The abstracts will feature encouraging findings from key elamipretide trials, including MMPOWER-3, highlighting improvements in the six minute walk test in genetic subgroups with mtDNA replisome disorders, and TAZPOWER, showing improvement in key biomarkers of mitochondrial dysfunction to potentially treat skeletal muscle wasting and cardiomyopathies. The presentations will be available to conference attendees via the conference website.

Date and Time: Saturday, December 12th, 1:55-2:45 p.m. ET

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 and Becker muscular dystrophies and Friedreich's ataxia, rare mitochondrial diseases entailing nuclear DNA mutations, such as POLG-related disorders, 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. We have optimized our discovery platform to identify novel mitochondria-targeted compounds, including SBT-259, the SBT-550 series of compounds, and other compounds which may be nominated as therapeutic product candidates or utilized as scaffolds to deliver other compounds to mitochondria.
