Tenaya Therapeutics Reports Third Quarter 2025 Financial Results and Provides Business Update Tenaya Therapeutics, Inc. Mon, November 10, 2025 at 6:00 AM CST 13 min read TNYA Tenaya Therapeutics, Inc. Presentation of MyPEAK-1 Data and the American Heart Association Scientific Sessions Showed Consistent, Deeper, and Durable Improvement in Measures of Hypertrophy for Cohort 1 Patients Initial TN-201 Cohort 2 Data Demonstrated Early Dose Responsive Increases in TN-201 Transduction and MyBP-C Protein Expression Completed Dosing in Cohort 2 of RIDGE™-1 Trial of TN-401 for PKP2-associated ARVC; Cohort 1 Data On Track for Fourth Quarter Company Presentation Tenaya Management to Review New MyPEAK-1 Data on Webcast Call for Analysts and Investors Today at 8:00 a.m. EST SOUTH SAN FRANCISCO, Calif., Nov. 10, 2025 (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 announced financial results for the third quarter ended September 30, 2025, and provided a corporate update. “Throughout the third quarter, we made important steps advancing our two lead gene therapy programs to provide transformative treatments to patients with serious genetic cardiomyopathies,” said Faraz Ali, Chief Executive Officer of Tenaya. “TN-201 and TN-401 each received positive recommendations from their respective Data Safety Monitoring Boards to advance into the dose expansion cohorts reflecting confidence in each product’s emerging safety profile. We were particularly pleased with the positive safety and promising clinical data presented on TN-201 as a potential treatment for MYBPC3 -associated HCM at the recent AHA Scientific Sessions. We also look forward to sharing meaningful safety and interim biopsy and efficacy data from the RIDGE-1 trial of TN-401 for patients with PKP2 -associated ARVC in the coming weeks.” Business and Program Updates TN-201 – Gene Therapy for MYBPC3-Associated Hypertrophic Cardiomyopathy (HCM) New data from the Phase 1b/2a MyPEAK-1 clinical trial of TN-201 were presented by Milind Desai, M.D., M.B.A., director of the Hypertrophic Cardiomyopathy Center at Cleveland Clinic and vice chair, Heart Vascular Thoracic Institute, Cleveland Clinic as a late-breaking oral presentation at the American Heart Association (AHA) Scientific Sessions on Saturday, November 8, 2025. The AHA presentation included updated data from Cohort 1 patients at ≥52-weeks of follow-up, as well as safety and available biopsy results for Cohort 2 patients. TN-201 achieved robust transduction and durable expression with dose-dependent increase in MyBP-C protein. Among Cohort 1 patients for whom there was greater than one year of follow up, decreases in circulating biomarkers and reductions in measures of left ventricular hypertrophy deepened over time. The data showed that single administration of TN-201 gene therapy was generally well-tolerated at both the 3E13 vg/kg and 6E13 vg/kg dose levels and immunogenicity was well managed through monitoring and individualized tapering of immunosuppressives. MyPEAK-1 is a multi-center, open-label, dose-escalation trial designed to assess safety, tolerability and clinical efficacy of a one-time intravenous infusion of TN-201 in treating patients with HCM caused by mutations in the MYBPC3 gene. A total of seven patients have been dosed with TN-201 to date. The independent Data Safety Monitoring Board (DSMB) for the MyPEAK-1 trial reviewed all available safety data over the summer and determined that TN-201 had an acceptable safety profile to enroll dose expansion cohorts at either the 3E13 vg/kg or 6E13 vg/kg dose level. There have been no new meaningful safety events associated with TN-201 since the DSMB review. Following a proactive outreach to the U.S. Food and Drug Administration (FDA) related to future plans for the TN-201 program, Tenaya is preparing a protocol amendment to the MyPEAK-1 clinical trial. The changes reflected in the amendment primarily focus on standardizing activities related to patient monitoring and management of the immunosuppressive regimen across trial sites. During this time, MyPEAK-1 is on clinical hold. Tenaya is working swiftly and collaboratively with the FDA to resolve the clinical hold and intends to resume dosing once the protocol changes have been implemented at trial sites The company does not expect the hold to impact data milestones or development timelines. In September 2025, results from a seroprevalence study of 100 adults with symptomatic MYBPC3 -associated HCM were published in Frontiers in Medicine . Pre-existing immunity to AAV9 was absent or low in most MYBPC3 -associated HCM patients, finding that nearly 95% would be below Nab titers of 1:80, the maximum allowable AAV9 titer threshold in the MyPEAK-1 gene therapy trial. (Nab) thresholds for AAV gene therapy trials. The study also indicated that either NAb or total antibody (TAb) assays may be suitable for patient eligibility screening. In August 2025, Tenaya presented interim data from the ongoing MyClimb TM natural history study of pediatric patients with MYBPC3- associated hypertrophic cardiomyopathy (HCM) at the European Society of Cardiology Congress. These data offer actionable information for predicting those patients who may be at higher risk of death or severe complications. The study enrolled more than 200 MYBPC3 -associated HCM individuals diagnosed before the age of 18 across 29 clinical sites worldwide. MyClimb is believed to be the largest natural history study evaluating this patient population. Among the findings: 93% of participants had the nonobstructive HCM phenotype, for which there are currently no approved treatment options. MyClimb data demonstrates that children with MYBPC3 -associated cardiomyopathy are at risk for severe morbidity and life-altering outcomes, even in childhood, including arrhythmia-related complications, heart failure-related hospitalizations, heart transplant, and death. Disease severity and age of diagnosis correlate to genetic inheritance patterns (homozygous, compound heterozygous and heterozygous). Initial modeling suggest Left Ventricular Mass Index (LVMI) was a significant predictor of risk in compound heterozygous and heterozygous groups and may serve as an appropriate surrogate marker of treatment efficacy in potential future studies. Story Continues TN-401 – Gene Therapy for PKP2-Associated Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC) Tenaya has completed enrollment and dosing of three patients at the 6E13 vg/kg dose (Cohort 2) in the Phase 1b RIDGE-1 clinical trial of TN-401. RIDGE-1 is a multi-center, open-label, dose-escalation trial designed to assess safety, tolerability and clinical efficacy of a one-time intravenous infusion of TN-401 in treating patients with PKP2 -associated ARVC. Tenaya expects to share initial safety and biopsy data from the first three patients enrolled and dosed in RIDGE-1 at the 3E13 vg/kg dose (Cohort 1) in a company presentation before year-end 2025. In October 2025, Tenaya presented a poster detailing the RIDGE-1 clinical trial design, including methodologies for measuring biopsy samples for TN-401 DNA and mRNA and PKP2 protein level changes at the European Society of Gene and Cell Therapy 2025 (ESGCT 2025) Annual Congress. In July 2025, the RIDGE-1 DSMB reviewed all available data from Cohort 1 and issued a positive recommendation regarding enrollment of Cohort 2 and enrollment of additional patients in an expansion arm at the 3E13 vg/kg dose. Research and Business Updates In a late-breaking presentation at the AHA Scientific Sessions, Tenaya presented new preclinical data on significant and durable improvement of cardiac function in a pig model of ischemic heart failure, achieved with a proprietary in vivo reprogramming cocktail that induces cardiac regeneration when delivered precisely with a clinically relevant catheter. In October 2025, Tenaya published a paper in the Journal of the American College of Cardiology (JACC), which highlighted the potential benefit of decreased MTSS1 expression in dilated cardiomyopathy, a severe form of heart failure. The paper details Tenaya's novel target identification and validation platform which utilizes human iPSC-derived cardiomyopathy models, specialized high-throughput screening combined with artificial intelligence (AI) and engineered heart tissue to characterize the role of MTSS1 in modulating contractile function. In August 2025, Tenaya hosted an educational webinar with Michael Previs, Ph.D. Associate Professor of Cellular, Molecular, and Biomedical Sciences at the University of Vermont focused on methods for measuring protein expression in cardiac gene therapies. The session highlighted the value of measuring protein level changes as an early indicator of gene therapy’s potential, Tenaya’s use of liquid chromatography – mass spectrometry normalized to myosin to more accurately quantify protein levels and the challenges inherent in exact measurements given sample to sample variability. An archived replay of the webinar is available under “ News & Events ” within the Investors section on the Tenaya website.
