Provides Business Update

Dosing of First Patient in Phase 1b Trial of TN-201 On Track to Occur in Q3 2023

Data from Phase 1 Clinical Trial of TN-301 Accepted for Presentation at HFSA 2023

IND Application for TN-401 Anticipated in Second Half 2023

Second Quarter Cash and Investments of $152 Million;
Runway to Fund Operations into First Half 2025

SOUTH SAN FRANCISCO, Calif., August 9, 2023 -- 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 reported financial results and provided a corporate update for the second quarter ended June 30, 2023.

“We are looking ahead to important near-term milestones across all our programs. Dosing the first patient in our first clinical trial for TN-201 will be a significant moment for our company and bring us one step closer to bringing much-needed solutions to those impacted by genetic HCM,” said Faraz Ali, Chief Executive Officer of Tenaya. “We are also looking forward to presenting healthy participant data from our TN-301 small molecule program and filing the IND for our TN-401 gene therapy candidate later this year. Our continued progress is supported by our unwavering commitment to fight heart disease on behalf of individuals and families.”

Business and Program UpdatesTN-201 – Gene Therapy for MYBPC3-Associated Hypertrophic Cardiomyopathy (HCM)

•In April 2023, the U.S. Food and Drug Administration (FDA) granted Fast Track designation for Tenaya’s lead gene therapy program, TN-201. Companies with therapies that receive the Fast Track designation are eligible for more frequent communication with the agency and may qualify for Accelerated Approval and Priority Review if relevant criteria are met.

•Tenaya anticipates dosing its first patient in the “MyPeak-1” Phase 1b multi-center, open-label, dose-escalation clinical trial of TN-201 during the third quarter of 2023 (ClinicalTrials.gov #NCT05836259).

oThe Phase 1b trial is designed to assess the safety, tolerability and pharmacodynamics of a one-time intravenous infusion of TN-201 in symptomatic adults with MYBPC3-associated HCM. Initial data from the MyPeak-1 clinical trial are anticipated in 2024.

•In July 2023, Tenaya received notification from the U.S. Patent and Trademarks Office (USPTO) that a notice of allowance has been issued for patent application No. 17/581,576. The allowed patent application includes claims covering a method of treating HCM or cardiomyopathy caused by a MYBPC3 mutation and expands upon Tenaya’s existing composition of matter protections by extending coverage to methods of use as the company continues to enhance its protection around different aspects of the TN-201 gene therapy program. The new patent issuing from the allowed patent application is expected to expire no earlier than February 2041.

TN-301 – Small Molecule HDAC6 Inhibitor for Heart Failure with Preserved Ejection Fraction (HFpEF)

•Data from Tenaya’s Phase 1 clinical trial of TN-301 in healthy volunteers have been accepted for presentation at the Heart Failure Society of America’s (HFSA) Annual Scientific Meeting, taking place October 6-9,2023.

oTenaya has completed the Phase 1 clinical trial of TN-301 in healthy participants. No dose-limiting toxicities were reported across a wide range of doses andinitial target engagement, measured by the biomarker tubulin acetylation, was achieved.

oThe randomized, double-blind, placebo-controlled clinical trial was designed to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of escalating oral doses of TN-301 to help guide dosing in future studies.

•Results from preclinical studies testing the combination of HDAC6 inhibition with SGLT2 inhibition in a validated model of HFpEF have also been accepted for presentation at the upcoming HFSA meeting.

•Preclinical data from the TN-301 programpresented on August 1, 2023, at the American Heart Association’s Basic Cardiovascular Sciences (BCVS) Scientific Session suggest HDAC6 inhibition may improve undesirable HFpEF phenotype characteristics such as dysregulated metabolism, fibrosis and hypertrophy.

TN-401 – Gene Therapy for PKP2-Associated Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC)

•Tenaya plans to submit an Investigational New Drug application (IND) to the FDA for TN-401 for the potential treatment of ARVC caused by PKP2 genetic mutations in the second half of 2023. A single dose of TN-401 is designed to deliver a fully functional PKP2 gene to cardiomyocytes in the heart and restore production of the plakophilin 2 protein in order to prevent arrhythmia and reverse disease following a single dose.

•Tenaya presented data from a new preclinical mouse model at BCVS on August 1, 2023, showing that a single dose of gene therapy prevented ARVC development and significantly prolonged survival.

•In June 2023, Tenaya received notification from the USPTO that a notice of allowance has been issued for patent application No. 17/390,395. The new patent issuing from the allowed patent application will be the first patent issued by the USPTO to cover an AAV gene therapy for PKP2 and is expected to expire no earlier than July 2041.

Research

Tenaya researchers also presented new data at BCVS on August 1, 2023, detailing the company’s drug discovery capabilities for identifying human genetic targets in models of human heart conditions.

Tenaya’s novel high throughput screening methods in human induced pluripotent stem cells derived cardiomyocytes were applied to identifying genes of interest in heart muscle cells.

Second Quarter 2023 Financial Highlights

•Cash Position and guidance: As of June 30, 2023, cash, cash equivalents and investments in marketable securities were $151.6 million. Tenaya expects current cash, cash equivalents and investments in marketable securities (current and noncurrent) will be sufficient to fund the company into the first half of 2025.

•Research & Development (R&D) Expenses: R&D expenses for the quarter ended June 30, 2023, were $26.5 million. Non-cash stock-based compensation included in R&D expense was $1.8 million for the quarter ended June 30, 2023.

•General & Administrative (G&A) Expenses: G&A expenses for the quarter ended June 30, 2023, were $8.6 million. Non-cash stock-based compensation included in G&A expense was $2.1 million for the quarter ended June 30, 2023.

•Net Loss: Net loss for the quarter ended June 30, 2023, was $33.3 million, or $0.45 per share.
