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.

ST. GALLEN, SWITZERLAND, March 19, 2024 /PRNewswire/ -- CSL Vifor today announced that Health Canada has authorized Ferinject (ferric carboxymaltose) for the intravenous (IV) treatment of iron deficiency anemia in adult and pediatric patients one year of age and older when oral iron preparations are not tolerated or are ineffective, as well as for the treatment of iron deficiency in adult patients with heart failure and New York Heart Association (NYHA) class II/III* 1 to improve exercise capacity.2 Ferinject has now received marketing authorization in 87 countries worldwide. Research shows that rates of iron deficiency are even higher than previously reported in Canada, with the condition particularly prevalent in women of reproductive age3 and children4. "While iron deficiency and associated anemia are some of the most prevalent medical conditions on a global scale, it is easily diagnosed and treatable," said Prof. Dr. Justin Ezekowitz, Director of Cardiovascular Research and Cardiologist at the University of Alberta, Canada. "The news of a new treatment option tested in clinical trials is welcomed, given that oral irons may not be able to adequately deliver the desired outcomes for Canadian patients with heart failure impacted by iron deficiency." Iron deficiency affects one in every two hospitalized patients with heart failure5. Iron deficiency is often accompanied by reduced exercise tolerance and untreated iron deficiency may result in anemia and worsening NYHA class, with reduced quality of life and eventually increased risk of hospitalization 6,7,8 "The approval by Health Canada marks an important step forward for the treatment of iron deficiency anemia as well as iron deficiency in heart failure and supports our promise to patients and public health," said Dr. Vinicius Gomes de Lima, Head of Global Medical Affairs, CSL Vifor. "We are confident that our now approved IV iron therapy can make a meaningful contribution to achieve key therapeutic goals in the treatment of these patients." Marketing authorization in Canada is based on a comprehensive clinical data package and totality of evidence from CSL Vifor's cardiology studies. In Canada, Ferinject® is commercialized through CSL Behring Canada, Inc., with availability expected in the second half of 2024. * The New York Heart Association Functional Classification is used by Healthcare Professionals to classify patients' heart failure based on the severity of their symptoms. Patients who have a slight or marked limitation of their physical activity due to fatigue, palpitation and/or dyspnea are considered to have class II or class III heart failure, respectively.9 About CSL Vifor CSL Vifor is a global partner of choice for pharmaceuticals and innovative, leading therapies in iron deficiency and nephrology.

About iron deficiency and associated anemia Iron plays a vital role in many bodily processes, including the production of red blood cells, effective heart and brain function, and the prevention of infection and illness. Without enough iron, the body is unable to function properly. Common symptoms include fatigue, dizziness, and shortness of breath. Iron deficiency and iron deficiency anemia are estimated to affect one in three people worldwide11, yet despite the serious consequences and high prevalence12, the conditions remain under-recognized. The effects of iron deficiency differ from person to person but can be linked to an overall decline in general health and well-being13. Iron deficiency and iron deficiency anemia can be debilitating, exacerbate an underlying chronic disease and lead to increased morbidity and mortality13. Common symptoms include fatigue 13,14,15 pale skin14, brittle nails14, 16, craving non-food items such as dirt, clay and ice17, and an inability to concentrate13, 18. In children, iron deficiency anemia can significantly impair cognitive and motor development19,20,21. Multiple organizations, including the World Health Organization (WHO), UNICEF and the U.S. Agency for International Development (USAID) have called for a comprehensive anemia monitoring framework.
