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.

STOCKHOLM, March 19, 2024 /PRNewswire/ -- BioArctic AB (publ) (STO: BIOA B) announced today that BioArctic's founder, Professor Lars Lannfelt, was awarded the European Grand Prix for his research on Alzheimer's disease at the anniversary gala for La Fondation Recherche Alzheimer in Paris on March 18. The prize was presented by the President of France, Emmanuel Macron. Professor Lannfelt received the award for his groundbreaking research, which has played a significant role in the scientific progress in the field over decades, leading to the development of lecanemab, a disease-modifying treatment for early Alzheimer's disease approved in the U.S., Japan and China. "Being able to give hope and contribute to the treatment of patients affected by Alzheimer's disease is what has driven me throughout my research life," said Professor Lars Lannfelt. "It is inspiring to see how research in this field has now begun to take quantum leaps with the development of treatments such as lecanemab which demonstrated meaningful benefits to patients in the global Phase 3 Clarity AD trial using gold standard endpoints. Coupled with the introduction of modern diagnostic methods, I am convinced that we are facing a paradigm shift where, in time, we will be able to offer not just a slowdown in the progression of the disease but eventually even stopping the disease process." Professor Lars Lannfelt founded BioArctic together with Pär Gellerfors in 2003 to develop an antibody treatment based on Lannfelt's groundbreaking discoveries of the role of amyloid-beta protein in Alzheimer's disease. These discoveries are the basis for lecanemab, an antibody treatment developed in collaboration with the Japanese company Eisai. By binding to specific forms of amyloid-beta, which causes Alzheimer's disease, lecanemab helps to clear them from the brain, thereby altering the course of the disease. La Fondation Recherche Alzheimer was founded in 2004 and aims to improve the diagnosis of Alzheimer's disease and pave the way for effective treatments. This is done by focusing their operations on financing research with a focus on early detection, development of new drugs and treatments, and improving care and support for patients and their families. The information was released for public disclosure, through the agency of the contact persons below, on March 19, 2024, at 08.00 a.m. CET. For further information, please contact: Oskar Bosson, VP Communications and IR E-mail: [email protected] Phone: +46 70 410 71 80 Jiang Millington, Director Corporate Communication and Social Media E-mail: [email protected] Phone: +46 79 33 99 166 About lecanemab Lecanemab is the result of a strategic research collaboration between BioArctic and Eisai. Lecanemab is a humanized IgG1 (immunoglobulin gamma 1) monoclonal antibody targeting aggregated soluble and insoluble forms of amyloid beta (Aβ). Lecanemab is approved in the USA, Japan, and China under the brand name Leqembi®. About the collaboration between BioArctic and Eisai Since 2005, BioArctic has a long-term collaboration with Eisai regarding the development and commercialization of drugs for the treatment of Alzheimer's disease. The most important agreements are the Development and Commercialization Agreement for the lecanemab antibody, which was signed 2007, and the Development and Commercialization agreement for the antibody LEQEMBI back-up for Alzheimer's disease, which was signed 2015. In 2014, Eisai and Biogen entered into a joint development and commercialization agreement for lecanemab. Eisai is responsible for the clinical development, application for market approval and commercialization of the products for Alzheimer's disease. BioArctic has the right to commercialize lecanemab in the Nordic region under certain conditions and is currently preparing for commercialization in the Nordics together with Eisai. BioArctic has no development costs for lecanemab in Alzheimer's disease and is entitled to payments in connection with regulatory approvals, and sales milestones as well as royalties on global sales. About BioArctic AB BioArctic AB (publ) is a Swedish research-based biopharma company focusing on disease-modifying treatments for neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease and ALS.
