Announcement
Tenaya Therapeutics, Inc. announced that interim data from the first three patients enrolled in the company's MyPEAK-1 Phase 1b/2 clinical trial of TN-201 were highlighted in a Late-Breaker presentation at the 2025 American College of Cardiology Scientific Sessions (ACC.25).
AI Summary
In March 2025, Tenaya Therapeutics, Inc. announced encouraging interim data from the first three patients treated with TN-201 in its MyPEAK-1 Phase 1b/2 clinical trial. The data was featured in a Late-Breaker presentation at the 2025 American College of Cardiology Scientific Sessions (ACC.25). TN-201 is a gene therapy developed to treat MYBPC3-associated hypertrophic cardiomyopathy by delivering a functional MYBPC3 gene to heart cells. The initial results showed that the treatment was generally well tolerated at the 3E13 vg/kg dose, with most adverse events being mild, manageable, or reversible. Serial biopsy data demonstrated robust transduction and increasing RNA levels over time, indicating positive therapeutic effects. The early safety profile and encouraging biological responses provide optimism that TN-201 could impact the treatment landscape for patients with this aggressive form of heart disease.

- Indication:
- Fully functional MYBPC3 gene
Announcement
Tenaya Therapeutics, Inc announced the publications of positive preclinical data for TN-201, the company's gene therapy candidate for Myosin-Binding Protein C3 (MYBPC3)-associated hypertrophic cardiomyopathy (HCM), in Nature Communications.
AI Summary
Tenaya Therapeutics recently published positive preclinical data for TN-201, its gene therapy candidate for treating MYBPC3-associated hypertrophic cardiomyopathy (HCM). The study, appearing in Nature Communications, shows that TN-201 delivers a working copy of the MYBPC3 gene to heart muscle cells using an AAV9 vector through a single intravenous infusion. This approach increases the levels of MyBP-C protein, which is often insufficient in patients with this genetic heart condition.
The data demonstrated that even at low dosages, TN-201 produces dose-dependent increases in MyBP-C protein and improves key measures of cardiac function, including the reversal of left ventricular hypertrophy. These promising results support further clinical development of TN-201 and offer hope for a new treatment that targets the underlying cause of this severe heart disorder.

Announcement
Tenaya Therapeutics, Inc. announced that the first patient has been dosed with TN-401 gene therapy in the RIDGE-1 Phase 1b clinical trial at the University of California, San Francisco.
AI Summary
Tenaya Therapeutics recently reached a major milestone by dosing the first patient in its RIDGE-1 Phase 1b clinical trial at the University of California, San Francisco. This early-stage study is testing TN-401, an AAV9-based gene therapy designed to treat arrhythmogenic right ventricular cardiomyopathy (ARVC) caused by mutations in the PKP2 gene.
TN-401 works by delivering a fully functional copy of the PKP2 gene to heart muscle cells, aiming to restore protein levels that are deficient in patients with ARVC. The therapy is expected to repair cell-to-cell connections in the heart, potentially reducing abnormal heart rhythms and disease progression. The trial, which involves a one-time intravenous dose, will help determine the safety, tolerability, and initial clinical effectiveness of TN-401, with early data anticipated in 2025.
