Tenaya Therapeutics Posts Strong Q2 Results and Future Plans

Tenaya Therapeutics Shows Progress in Q2 Financial Results

Tenaya Therapeutics, Inc. (NASDAQ: TNYA), a leading biotechnology company focused on innovative therapies for heart disease, has recently reported its financial results for the second quarter of 2025. These results showcase the company’s commitment towards advancing gene therapy solutions, particularly for devastating heart conditions.

Key Enrollment Milestones Achieved

During the first half of 2025, Tenaya successfully completed the target enrollment for its pivotal gene therapy clinical trials: TN-201 aimed at treating MYBPC3-associated hypertrophic cardiomyopathy (HCM), and TN-401 for PKP2-associated arrhythmogenic right ventricular cardiomyopathy (ARVC). The positive evaluations from independent Data Safety Monitoring Boards (DSMBs) have been significant, allowing further patient enrollment and expansion of trial cohorts.

Advances in Gene Therapy Programs

For TN-201, in May 2025, the company enrolled and dosed additional patients in its MyPEAK™-1 Phase 1b/2 clinical trial. This trial is designed to assess the safety and efficacy of a one-time intravenous infusion of TN-201. Interim data from previous patients indicated promising results; all participants who showed severely impacted health at baseline improved to NYHA Class I status, with notable reductions in cardiac hypertrophy.

Optimizing TN-401 for ARVC Patients

The enrollment for the RIDGE-1 Phase 1b trial, focusing on TN-401, has also shown progress. Initially, three patients were dosed at 3E13 vg/kg, followed by a recent recommendation from the DSMB to escalate the dose level to 6E13 vg/kg. This escalation aims to leverage existing safety data while providing promising intervention options for patients suffering from PKP2 mutations.

Financial Overview for the Quarter

As of June 30, 2025, Tenaya reported cash and investments amounting to $71.7 million, which is expected to extend their operational timeline into the second half of 2026. The second quarter saw a decrease in Research and Development expenses to $17.4 million, down from $22.6 million in the same period of 2024, reflecting prudent financial management during a growth period.

Reducing Operational Expenses

General and Administrative expenses also decreased to $6.7 million in Q2 2025, compared to $8.2 million in Q2 2024. This reduction indicates Tenaya's efficiency in managing resources while advancing its clinical objectives. The net loss for the quarter was reported at $23.3 million, which translates to a loss per share of $0.14, compared to a more substantial loss in previous quarters.

Upcoming Clinical Data Releases

Tenaya Therapeutics looks forward to sharing meaningful data readouts from both TN-201 and TN-401 trials in the fourth quarter of 2025. These results are anticipated to be crucial in the company’s ongoing mission to develop potentially transformative therapies for heart diseases linked to genetic mutations.

Community Engagement and Next Steps

In addition to trial updates, Tenaya has plans to engage the scientific community by hosting a Virtual Key Opinion Leader event titled "Measuring Protein Expression in Cardiac Gene Therapy" on August 19, 2025. This dialogue will include insights from experts in the field, aimed at fostering knowledge exchange regarding cardiac gene therapies.
