BOSTON, Jan. 21, 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 the initiation of a first-in-human Phase 1 trial evaluating its second generation pipeline compound, SBT-272, in healthy subjects. "We ...
"We are excited to advance our second generation of mitochondrial therapeutics into the clinic," said
The Phase 1 trial is a double-blind, placebo-controlled, single-ascending dose study enrolling up to 40 healthy subjects across multiple cohorts. SBT-272 is being administered orally in the study. As a primary objective, the study will evaluate safety and tolerability of SBT-272. Secondary objectives include an analysis of the pharmacokinetic profile and appropriate dose range.
SBT-272 is a novel peptidomimetic being developed for the treatment of neurodegenerative diseases involving mitochondrial dysfunction. SBT-272 has been shown to increase adenosine triphosphate (ATP) production and decrease levels of reactive oxygen species (ROS) in dysfunctional mitochondria in preclinical studies. SBT-272 demonstrates higher mitochondrial uptake, greater concentrations in the brain, and improved oral bioavailability relative to elamipretide, Stealth's first-in-class lead compound. Treatment with SBT-272 was associated with a dose-dependent delay in the onset of neurological disease, a reduction in systemic markers of neurodegeneration and prolonged lifespan in a mouse model of amyotrophic lateral sclerosis (ALS), a progressive neurodegenerative disease characterized by motor neuron deterioration and muscle atrophy. The compound is currently being evaluated in another ALS preclinical model, as well as in a preclinical model indicative of activity in multiple system atrophy (MSA), a neurological disorder leading to parkinsonism, cerebellar ataxia, dysautonomia and other motor and non-motor symptoms. Mitochondrial dysfunction is believed to contribute to the progression of ALS and MSA, as well as other neurodegenerative diseases including Parkinson's,
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, collectively known as primary mitochondrial diseases, and are also involved in many common age-related diseases. We believe our lead product candidate, elamipretide, has the potential to treat both rare genetic and common age-related mitochondrial diseases. We are studying elamipretide in Barth syndrome, geographic atrophy associated with dry age-related macular degeneration and Leber's hereditary optic neuropathy. Our newest clinical stage candidate, SBT-272, is being evaluated for rare neurodegenerative disease indications. 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 disease 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.
