Received Rare Pediatric Disease Designation from U.S. Food and Drug Administration for TN-201 for MYBPC3-associated Hypertrophic Cardiomyopathy Received UK Clearance to Initiate Clinical Testing of TN-401 for PKP2-Associated Arrhythmogenic Right Ventricular Cardiomyopathy Established $45 Million Credit Facility with Silicon Valley Bank to Provide Financial Flexibility Ahead of Multiple Potential Milestones SOUTH SAN FRANCISCO, Calif., Aug. 08, 2024 (GLOBE NEWSWIRE) -- Tenaya Therapeutics, Inc. (NASDAQ: TNYA), a clinical-stage biotechnology company with a mission to discover, develop and deliver potentially curative therapies that address the underlying causes of heart disease, today reported financial results for the second quarter ended June 30, 2024, and provided a corporate update. “We remain laser focused on advancing our lead gene therapy candidates, as we prepare to report initial data from our first-in-human study of TN-201 in the second half and to dose the first patient in our Phase 1b trial of TN-401 in the fourth quarter of 2024. Our focus on clinical execution now and in the future is evident with more than forty sites in seven countries across our interventional and natural history studies for both programs, and with the recent receipt of rare pediatric disease designation for MYBPC3-associated HCM in infants, children and adolescents,” said Faraz Ali, Chief Executive Officer of Tenaya. “Consistent with that focus, we have taken important steps to increase our financial flexibility in anticipation of additional clinical data readouts in 2025.” Business and Program UpdatesTN-201 – Gene Therapy for MYBPC3-Associated Hypertrophic Cardiomyopathy (HCM) Screening and enrollment continue in MyPEAK™-1, a Phase 1b multi-center, open-label, dose-escalation trial designed to assess safety, tolerability and clinical efficacy of a one-time intravenous infusion of TN-201 with a total of nine clinical sites activated. Tenaya anticipates sharing interim Phase 1b results from the first cohort of patients in MyPEAK-1 in the second half of 2024.TN-201 was granted rare pediatric disease designation (RPDD) by the U.S. Food and Drug Administration (FDA) for the treatment of MYBPC3-associated HCM in children, adolescents and young adults. The FDA defines rare pediatric diseases as rare diseases (those with fewer than 200,000 cases in the United States) that are serious or life threatening and primarily affect individuals under 18 years of age. This is the first RPDD to be granted for MYBPC3-associated HCM. As a result of being granted RPDD, if TN-201 is approved to treat MYBPC3-associated HCM in patients under age 18, Tenaya may qualify to receive a priority review voucher that may be redeemed to receive priority review for a different product, or which may be transferred or sold to another sponsor. In 2021, Tenaya initiated a non-interventional natural history study, know as MyClimb, designed to understand MYBPC3-associated HCM in infants, children and teens which is ongoing at more than twenty sites in the U.S., Canada, and Europe. TN-401 – Gene Therapy for PKP2-Associated Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) Tenaya has activated four clinical sites in RIDGE™-1 and plans to begin dosing patients in the trial during the fourth quarter of 2024. RIDGE-1 is a global multicenter, open-label, dose-escalation trial designed to assess safety, tolerability and clinical efficacy of a one-time intravenous infusion of TN-401 for the treatment of ARVC caused by mutations to the PKP2 gene.Tenaya received clearance of its Clinical Trial Application by the U.K.'s Medicines and Healthcare Products Regulatory Agency and plans to activate RIDGE-1 clinical sites in the U.K.In June 2024, Tenaya shared interim data from the ongoing RIDGE™ seroprevalence and natural history study indicating that adults with PKP2-associated ARVC have low levels of preexisting antibodies to adeno-associated serotype 9 (AAV9), the viral vector used in TN-401. Forty-eight of 57 volunteers with PKP2-associated ARVC, or 84%, had neutralizing antibody titers of less than 1:20 and would meet eligibility criteria for RIDGE-1. These data were presented at the International Congress on Electrocardiology held in Lund, Sweden. Tenaya is currently enrolling adult PKP2-associated ARVC patients in the RIDGE natural history and seroprevalence study at 18 clinical sites across the U.S. and Europe. Research and Manufacturing In May 2024, Tenaya’s Research and Manufacturing teams presented multiple posters at the American Society for Gene and Cell Therapy meeting detailing continued innovations related to its core capabilities, including gene editing, capsid engineering, promoter and regulatory elements, and manufacturing science.In July 2024, Tenaya received a notice of allowance from the U.S. Patent and Trademarks Office for U.S. Application No. 18/468,594 covering a Tenaya-owned optimized vector encoding the DWORF protein. This patent provides composition of matter protections for Tenaya’s DWORF gene therapy program for the treatment of dilated cardiomyopathy and/or heart failure with reduced ejection fraction and is expected to expire no earlier than 2042. Corporate Updates Tenaya announced that Leone Patterson, Chief Financial and Chief Business Officer, will be departing from the company to transition to a new role effective August 14, 2024.
