Current Research and Development Projects

Key Therapeutic Areas
Tenaya Therapeutics’ R&D efforts are primarily concentrated within the cardiovascular field, reflecting a commitment to addressing diseases that are the leading cause of death globally. The company focuses on:
- Rare Genetic Cardiovascular Disorders:
For instance, hypertrophic cardiomyopathy (HCM) caused by MYBPC3 gene mutations is a central target. TN-201, a gene therapy candidate, is specifically engineered to treat MYBPC3-associated HCM by restoring normal protein function.
- Arrhythmogenic Cardiomyopathy:
TN-401 is a gene therapy candidate designed to address arrhythmogenic right ventricular cardiomyopathy (ARVC) associated with PKP2 mutations. This candidate aims to rectify the genetic defects at the heart of ARVC and improve electrical and structural stability in heart tissue.
- Heart Failure with Preserved Ejection Fraction (HFpEF):
Recognizing the large unmet medical need in this condition, Tenaya has developed TN-301—a small molecule inhibitor targeting histone deacetylase 6 (HDAC6). This candidate is developed to improve myocardial relaxation and overall cardiac function in HFpEF patients.

In addition to these advanced programs, Tenaya continues to invest in multiple early-stage programs that are progressing through preclinical development. These efforts span a diverse range of therapeutic targets and modalities, including novel small molecule approaches backed by robust phenotypic screening technologies.

Pipeline and Development Stages
A hallmark of Tenaya Therapeutics’ strategy is its robust pipeline characterized by candidates at various development stages:

- Gene Therapy Programs:
- TN-201: This candidate targets MYBPC3-associated HCM and is currently in clinical development with active enrollment in the MyPEAK™-1 Phase 1b/2 trial. The research strategy includes detailed safety, biopsy, and biomarker assessments with initial data anticipated in the near future.
- TN-401: This product candidate is being developed to treat ARVC due to PKP2 mutations. It is progressing through preclinical development with plans to initiate clinical dosing and submit an Investigational New Drug (IND) application in the near term. The candidate also benefits from a natural history study (RIDGE™-1) to support its development.
- Small Molecule Development:
- TN-301: This small molecule HDAC6 inhibitor is designed for HFpEF. It has recently completed a first-in-human Phase 1 clinical trial in healthy adults, with dose escalation studies confirming favorable pharmacokinetics and biomarker engagement. The promising preclinical data—published in renowned journals such as Science Translational Medicine—underline its potential to improve diastolic function.
- Early-Stage Programs:
Tenaya’s pipeline also includes several early-stage projects that utilize its proprietary precision medicine platform. These projects are founded on advanced disease modeling techniques using human induced pluripotent stem cell-derived cardiomyocytes (iPSC-CMs) coupled with high-content imaging and machine learning algorithms. Such a platform enables the identification and validation of novel therapeutic targets across a variety of cardiovascular conditions.

Technological Approaches

Gene Therapy Platforms
At the core of Tenaya Therapeutics’ R&D is its integrated gene therapy platform. This platform is designed to:
- Target Genetic Roots of Cardiovascular Disease:
By focusing on adeno-associated virus (AAV) vectors, Tenaya’s gene therapies—such as TN-201 and TN-401—aim to replace defective genes or restore physiological protein levels in the heart. These approaches are built on robust preclinical data demonstrating durable disease reversal in murine models.
- Innovative Capsid Engineering:
The company is heavily invested in optimizing AAV capsids to enhance targeting specificity to cardiac tissue and reduce off-target distribution. This involves screening millions of variants from its proprietary libraries to engineer capsids that exhibit greater tropism for the heart.
- State-of-the-Art Manufacturing:
Recognizing the challenges of clinical-grade manufacturing for gene therapies, Tenaya has recently established a dedicated Genetic Medicines Manufacturing Center. This facility is designed to produce AAV-based products at scales appropriate for both early-phase clinical trials and eventual commercial manufacturing. The strategic commitment to in-house manufacturing enhances control over product quality, speed of production, and cost efficiencies.

Innovations and Techniques
Tenaya employs a multifaceted approach to innovation in its R&D:
- Precision Medicine Platform:
The company uses advanced phenotypic screening with human iPSC-CMs combined with machine learning algorithms. This system not only identifies novel targets with human tissue relevance but also provides a proof-of-concept that traditional animal models are sometimes insufficient for predicting clinical outcomes.
- Novel Delivery Methods:
In its clinical studies, Tenaya is investigating innovative delivery devices, such as a novel intra-endomyocardial injection catheter. This catheter allows for precise delivery of therapeutic agents directly into areas of myocardial injury, potentially enhancing the efficacy and safety of gene therapy interventions.
- Integrated Modalities:
By integrating gene therapy, cellular regeneration, and small molecule modalities within a single R&D framework, Tenaya demonstrates an ability to cross-validate therapeutic targets and leverage complementary approaches. This integration not only diversifies the pipeline but also enables the company to address multiple facets of cardiovascular pathology simultaneously.
- Advanced Biomarker and Data Analytics:
The use of deep phenotyping and scrutiny of biomarker engagement in early clinical trials, such as assessing tubulin acetylation as a target engagement marker in the case of TN-301, underscores the company’s reliance on quantifiable endpoints. These endpoints guide dose selection and optimize therapeutic windows during clinical studies.
