Should l Buy TNYA?
Tenaya Therapeutics presented preclinical data evaluating TN-301, the company's highly selective HDAC6 inhibitor, at the Muscular Dystrophy Association's Clinical & Scientific Conference 2026. In in vitro and in vivo models of Duchenne muscular dystrophy, TN-301 improved muscle performance and corrected key drivers of DMD cardiomyopathy. Key findings presented at MDA 2026 include: TN-301 treatment at doses as low as 3 mg/kg improved grip strength to wild-type levels within five weeks, whereas mdx mice treated with givinostat failed to reach wild-type performance. TN-301-mediated functional improvements were accompanied by reductions in circulating creatine kinase activity and favorable changes in gene expression, indicating reduced muscle cell injury. In cardiomyocytes derived from human DMD induced pluripotent stem cells, TN-301 corrected calcium handling abnormalities and mitochondrial dysfunction, while givinostat exacerbated these established drivers of DMD cardiomyopathy.

About TNYA
Tenaya Therapeutics, Inc. is a clinical-stage biotechnology company focused on discovering, developing, and delivering curative therapies that address the underlying drivers of heart disease. Its pipeline includes TN-201, TN-401, and TN-301. TN-201 is an adeno-associated virus serotype 9 (AAV9)-based gene therapy designed to deliver a working MYBPC3 gene to heart muscle cells via a single intravenous infusion, increasing MyBP-C protein levels to address the underlying cause of MYBPC3-associated HCM with the aim of halting or even reversing disease after a single dose. Its MyPEAK-1 Phase I b/2 clinical trial is an ongoing, multi-center, open-label, dose-escalating study designed to assess the safety, tolerability and clinical efficacy of a one-time intravenous infusion of TN-201 gene replacement therapy. TN-401 is its AAV9-based gene therapy being developed for the treatment of arrhythmogenic right ventricular cardiomyopathy (ARVC) due to disease-causing variants in the PKP2 gene.

Tenaya's TN-301 Outperforms Givinostat in DMD Cardiomyopathy
- Promising Preclinical Data: At the 2026 Muscular Dystrophy Association conference, Tenaya presented preclinical data showing that TN-301 significantly outperformed the approved pan-HDAC inhibitor Givinostat in improving muscle function and addressing DMD cardiomyopathy, highlighting its potential in treating cardiac, metabolic, and muscular diseases.
- Multi-Modal Mechanism: TN-301 operates through multiple mechanisms, including reducing inflammation and improving mitochondrial function, effectively correcting DMD-associated cardiomyocyte defects, and restoring muscle strength to wild-type levels in mouse models at a low dose of 3 mg/kg, showcasing its superior therapeutic effects.
- Good Safety Profile: In a Phase 1 clinical trial involving healthy adults, TN-301 demonstrated good tolerability across a wide dose range without serious adverse events or dose-limiting toxicities, indicating its safety and efficacy for clinical applications.
- Future Development Plans: Tenaya plans to advance TN-301 into Phase 2 clinical development targeting heart failure and DMD, aiming to address significant unmet needs in current treatments and drive the company's strategic growth in the biopharmaceutical sector.
