2024 Harrington Prize for Innovation in Medicine Recognizes Pioneering Work in Immunology CLEVELAND, March 19, 2024 /PRNewswire/ -- The eleventh annual Harrington Prize for Innovation in Medicine has been awarded to Arlene H. Sharpe, MD, PhD, Kolokotrones University Professor and Chair of the Department of Immunology at Harvard Medical School. The award recognizes her breakthrough discoveries in immune regulation, which have established foundational principles in immunology and led to new cancer therapies that act by boosting the immune response to cancer. The Harrington Prize for Innovation in Medicine, established in 2014 by the Harrington Discovery Institute at University Hospitals and the American Society for Clinical Investigation (ASCI), honors physician-scientists who have moved science forward with achievements notable for innovation, creativity and potential for clinical application. Dr. Sharpe's research in immunology has led to significant advances in medical treatments. Her work helped identify key pathways that restrain the activity of T lymphocytes (immune cells) to fight cancer. Her work defined the PD-1 pathway and its immunoinhibitory functions as well as the inhibitory functions of CTLA-4 to restrain the activity of the immune system. Dr. Sharpe's research thus laid the foundation for the development of 'immune checkpoint inhibitors', drugs that target PD-1 and related pathways. These therapies, including pembrolizumab and nivolumab, have been approved by the FDA for treating numerous types of cancer. They work by preventing inhibition of T cell function, thereby unleashing the body's immune system to fight cancer cells more effectively. This approach has become a cornerstone in cancer treatment strategies. "Dr. Sharpe's body of work has shaped our understanding of the role of the T cell in regulating the immune response. Her innovative scientific discoveries are among the best examples of bench-to-bedside work in the past three decades," said Benjamin D. Humphreys, MD, PhD, Joseph Friedman Professor of Renal Diseases in Medicine and Chief, Division of Nephrology, Washington University in St. Louis and 2023-2024 President of the ASCI. "Immune checkpoint inhibitors are drugs that allow for dramatic remission, and even cures, of cancers that had previously been considered untreatable. Dr. Sharpe's foundational insights have thus been harnessed to transform cancer therapy. Her work provides a beautiful example of physician impact through creative science," said Jonathan S. Stamler, MD, President, Harrington Discovery Institute, Robert S. and Sylvia K. Reitman Family Foundation Distinguished Professor of Cardiovascular Innovation and Professor of Medicine and of Biochemistry at University Hospitals and Case Western Reserve University. A committee composed of members of the ASCI Council and the Harrington Discovery Institute Scientific Advisory Board reviewed nominations from leading academic medical centers globally before selecting the 2024 Harrington Prize recipient. In addition to sharing the Prize's $20,000 honorarium, Dr. Sharpe will deliver the Harrington Prize Lecture at the 2024 AAP/ASCI/APSA Joint Meeting on April 5, will be a featured speaker at the 2024 Harrington Scientific Symposium May 22-23, and will publish an essay in the Journal of Clinical Investigation. The Harrington Prize has recognized outstanding and diverse innovations in medicine: 2014: Harry Dietz, MD, Johns Hopkins University, for his contributions to the understanding of the biology and treatment of Marfan syndrome, a disorder leading to deadly aneurysms in children and adults. 2015: Douglas R. Lowy, MD, The National Cancer Institute, in recognition of his discoveries that led to the development of the Human Papillomavirus vaccine to prevent cervical cancer. 2016: Jeffrey M. Friedman, MD, PhD, The Rockefeller University, for his discovery of leptin, which controls feeding behavior and is used to treat related clinical disorders. 2017: Jointly awarded to Daniel J.

SBT-589 showed mitochondrial protection across models of Friedreich's ataxia SBT-589 displayed cardioprotective effects in aggressive mouse model of FA cardiomyopathy Ongoing studies are expected to build on these insights as SBT-589 progresses through developmental stage-gates NEEDHAM, Mass., March 19, 2024 /PRNewswire/ -- Stealth BioTherapeutics Inc. (the "Company" or "Stealth"), a clinical-stage biotechnology company focused on the discovery, development, and commercialization of novel therapies for diseases involving mitochondrial dysfunction, announced today the presentation of new SBT-589 data demonstrating cardioprotective effects across pre-clinical models of Friedreich's ataxia (FA). The data were presented at the Wellcome Trust Conference on Mitochondrial Medicine – Therapeutic Development, held March 18-20, 2024, in Cambridge, England. FA is a chronic disease of metabolic disruption that is typically diagnosed in childhood or adolescence, is inexorably progressive and usually results in premature death from cardiomyopathy or heart failure. There are no approved therapies for the progressive cardiomyopathy, which is linked to severe mitochondrial dysfunction, and is the leading cause of early death in this devastating disease. SBT-589 is a promising novel molecule that acts on mitochondrial pathways essential for cellular health and energy production that are impaired in FA cardiomyopathy. To evaluate the potential of SBT-589 in FA, a series of studies were conducted in FA patient-derived cells, isolated heart mitochondria, and an aggressive mouse model of FA cardiomyopathy. SBT-589 improved bioenergetics in FA patient-derived cells and mitochondria. In an FA mouse model with prominent cardiac hypertrophy and aggressive mortality, mice treated with once-daily SBT-589 displayed significantly reduced cardiac hypertrophy and a delay in the onset of mortality compared to vehicle-treated mice. "Mitochondrial dysfunction is a central contributor to pathology in Friedreich's ataxia, a disease in which heart failure and sudden cardiac events are among the leading causes of mortality," said David A. Brown, Senior Vice President, Discovery. "Mitigating heart disease in FA is central to Stealth's ongoing efforts to improve the lives of individuals with FA. The new findings presented today support continued development of SBT-589 as a potentially disease-modifying therapy to address the unmet need in cardiomyopathy associated with Friedreich's ataxia." The data were presented by Dr. Laura E. Kropp, Senior Manager of Discovery Biology at Stealth, and recipient of the Keith Michael Andrus Cardiac Award from the Friedreich's Ataxia Research Alliance. About Friedreich's Ataxia Friedreich's ataxia is a rare genetic disease affecting an estimated 1 in 50,000 individuals in the United States. The disease is caused by a defect in the frataxin gene resulting in a relative deficiency of frataxin, leading to mitochondrial iron accumulation and oxidative stress. More than 90% of patients with Friedreich's ataxia experience progressive cardiomyopathy which usually becomes fatal by early adulthood and is the leading cause of early mortality. About Stealth BioTherapeutics Stealth BioTherapeutics is a clinical-stage biotechnology company focused on the discovery, development, and commercialization of novel therapies for age-related and rare genetic diseases involving mitochondrial dysfunction. The Company is initiating Phase 3 clinical trials of elamipretide, its lead investigational product candidate, in dry age-related macular degeneration. Elamipretide is also being tested in a fully enrolled Phase 3 clinical trial in primary mitochondrial myopathy, a rare skeletal myopathic disease caused by nuclear DNA mutations, and is the subject of a New Drug Application for Barth syndrome, an ultra-rare cardioskeletal disease. The Company is evaluating its second-generation clinical-stage candidate, SBT-272, for ophthalmic and neurological disease indications. The Company has a deep pipeline of novel mitochondria-targeted compounds under evaluation as therapeutic product candidates. Several of these lead compounds, including SBT-589, have progressed through pre-clinical development stage-gates and toward IND-enabling studies.
