BOSTON, Feb. 23, 2021 /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 company completed enrollment for ReCLAIM-2 (SPIAM-202), and expects top-line data in the first half of 2022. ReCLAIM-2 is a phase 2 randomized, double-masked, placebo-controlled study to evaluate the efficacy and pharmacokinetics of elamipretide in patients with dry age-related macular degeneration (AMD) with geographic atrophy (GA).
"Distorted vision, reduction in low luminance visual acuity, reduced visual acuity, and blurred vision are symptoms of dry AMD with geographic atrophy and have a negative impact on the quality of life of affected patients," said Dr. Jeff Heier, director of the retina service and retina research at Ophthalmic Consultants of Boston and Lead Investigator. "Data demonstrated in prior trials suggests elamipretide may be able to help our patients with dry AMD, and I was pleased to be able to offer our patients the opportunity to participate in this trial."
"We believe that mitochondria-targeted therapeutics offer a differentiated approach to treat diseases of aging, such as dry AMD, which significantly affects the independence of over a million elderly patients," said Reenie McCarthy, Stealth's CEO. "By targeting the bioenergetic deficits that drive pathology in this disease, we hope to improve visual function for affected patients. Completing enrollment of this trial represents a meaningful milestone in our mission to improve the health-span of patients suffering from diseases of aging and also fulfills the condition for additional funding ($10m) under the Development Funding Agreement announced in October 2020."
The ReCLAIM-2 study completed enrollment with 176 patients. The primary endpoint of the 48-week study will measure the low-luminance best-corrected visual acuity, which assesses visual function under low light conditions meant to represent dusk or indoor (artificial) lighting. Secondary functional endpoints are change in low-luminance reading acuity, best-corrected visual acuity (BCVA). Secondary imaging endpoints assessing the rate of progression of the disease include GA area as measured by fundus autofluorescence and optical coherence tomography.
In November 2018, the U.S. Food and Drug Administration granted Fast Track designation for elamipretide for patients with dry AMD with GA.
About Age-Related Macular Degeneration
AMD, a progressive eye condition that is the leading cause of blindness in adults, is estimated to affect approximately 10 million people in the U.S. AMD affects the center portion of the retina, called the macula, which is responsible for central vision and color perception. Although there are FDA-approved treatments for wet AMD, which affects approximately 10 percent of those suffering from the disease, there are no approved therapies for dry AMD. Dry AMD with GA, an advanced form of dry AMD, is characterized by central blind spots leading to permanent loss of vision. The disease is a major contributor to loss of independence and diminished quality of life in older persons.
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, such as POLG-related disorders, as well as ophthalmic diseases entailing mitochondrial dysfunction, such as dry AMD and Leber's hereditary optic neuropathy. 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 scaffolds to deliver other compounds to mitochondria.
