Stealth BioTherapeutics Announces Poster Presentation at 2020 Annual NEALS Meeting
BOSTON, Sept. 23, 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 company will present an abstract in a poster session at the upcoming 2020 Annual Northeast Amyotrophic Lateral Sclerosis (NEALS) Meeting, which is being held online from September 30th to October 1st. The selected poster has been awarded the 2020 Annual NEALS Meeting UMN/PLS Poster Award.
The poster, entitled "The mitochondrial targeted peptidomimetic SBT-272 protects cortical spinal motor neurons from mutant TDP43 pathology," demonstrates that SBT-272 protects upper motor neurons from mutant TDP43 driven neurodegeneration. TDP43 pathology has been observed in multiple neurodegenerative diseases, including Amyotrophic Lateral Sclerosis (ALS), Frontotemporal Lobar Degeneration (FTLD), Lewy Body Dementia (LBD), Progressive Supranuclear Palsy (PSP), and Alzheimer's Disease, and is believed to play a role in neuronal cell death. The data from this study supports further investigation of SBT-272 for the treatment of these and other neurodegenerative diseases in which TDP43 pathology is thought to contribute to disease burden.
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 and greater concentrations in the central nervous system 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). In addition, SBT-272 treatment was associated with the preservation of dopaminergic neurons in the substantia nigra of a mouse model of mutant alpha-synuclein driven neurodegeneration. Alpha-synucleinopathy is a common pathological feature of several neurodegenerative diseases, including Parkinson's Disease, Multiple Systems Atrophy and Alzheimer's Disease. Further preclinical evaluation of SBT-272 in the context of protein misfolding diseases which lead to mitochondrial dysfunction and subsequent neurodegeneration is on-going.
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.
