Tenaya Therapeutics Reports Third Quarter 2023 Financial Results and
Provides Business Update

Commenced Patient Dosing in MyPeak-1TM Phase 1b Trial of TN-201 in MYBPC3-Associated Hypertrophic Cardiomyopathy

Presented Positive Phase 1 Data for TN-301 for the Potential Treatment of Heart Failure with Preserved Ejection Fraction at HFSA 2023

TN-401 for PKP2-Associated ARVC Received FDA Clearance to Begin First-in-Human
Clinical Testing and Fast Track Designation

SOUTH SAN FRANCISCO, Calif., November 8, 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 third quarter ended September 30, 2023.

“The successful execution across all of our program milestones slated for 2023, including two gene therapy INDs cleared and the dosing of the first patient in our TN-201 clinical trial, represents the strong commitment and capabilities of our team,” said Faraz Ali, Chief Executive Officer of Tenaya. “We have momentum as we head into 2024, with three clinical-stage programs for the treatment of rare and prevalent heart conditions and unmatched capabilities focused on the discovery of precision heart disease medications.”

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

•In October 2023, Tenaya dosed the first patient in the MyPeak-1 Phase 1b clinical trial of
TN-201 for the treatment of myosin binding protein C3 (MYBPC3)-associated hypertrophic cardiomyopathy (HCM). MyPeak-1 (NCT05836259) is a multi-center, open-label, dose-escalation trial designed to assess safety, tolerability and clinical efficacy of a one-time intravenous infusion of TN-201.

oTenaya anticipates sharing initial data from the MyPeak-1 trial in 2024.

•In October 2023, Tenaya shared interim results from its ongoing seroprevalence study indicating that patients with MYBPC3-associated HCM have low levels of preexisting neutralizing antibodies to adeno-associated virus serotype 9 (AAV9) and the majority of patients could be eligible for TN-201 treatment in clinical trials.

oThe seroprevalence study is being conducted across 10 clinic sites. As of the data cut off in August 2023, 76 patients with MYBPC3-associated HCM were enrolled. These data were presented at the HCM Society (HCMS) Scientific Sessions.

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

•In October 2023, the U.S. Food and Drug Administration (FDA) notified Tenaya that clinical testing of TN-401 may proceed based on review of the company’s Investigational New Drug (IND) application.

oTenaya is advancing TN-401 into the clinic for the treatment of plakophilin-2 (PKP2)-associated arrhythmogenic right ventricular cardiomyopathy (ARVC), a dangerous condition estimated to effect 70,000 people in the U.S.

oThe company plans to initiate the RIDGE-1™ Phase 1b clinical trial of TN-401 at leading U.S. centers for ARVC treatment and is currently conducting a non-interventional seroprevalence and natural history study among PKP2-associated ARV patients.

ocGMP grade clinical trial material for TN-401 was produced at the 1000L scale at Tenaya’s Genetic Medicine Manufacturing Center.

•In November, TN-401 received Fast Track Designation from the FDA. The FDA Fast Track program is designed to facilitate the development and expedite the review of drug candidates intended to treat serious conditions and for which nonclinical data demonstrates the potential to address unmet medical need.

•In September 2023, Tenaya received Orphan Medicinal Product designation from the European Medicines Agency (EMA) for TN-401 for the potential treatment of ARVC caused by PKP2 genetic mutations. TN-401 has also Orphan Drug Designation from the U.S. FDA.

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

•In October 2023, Tenaya shared positive Phase 1 data for TN-301 at the 2023 Heart Failure Society of America (HFSA) Annual Scientific Meeting.

oThe Phase 1 trial enrolled 72 participants in two stages, single ascending doses (SAD) and multiple ascending doses (MAD).

oTN-301 was generally well tolerated across the broad range of doses studied. Pharmacokinetic (PK) results showed overall dose proportionality in the SAD and MAD stages of the study with a half-life supportive of once-daily dosing.

oRobust HDAC6 inhibition was observed and increasing doses and exposures with TN-301 correlated with increased pharmacodynamic (PD) effects. Plasma exposure and target engagement observed in this healthy participant study met or exceeded those required for maximal efficacy in preclinical studies.

•At HFSA Tenaya also presented new preclinical results demonstrating additive benefit of combining TYA-018 (an HDAC6 inhibitor structurally and functionally similar to TN-301) with empagliflozin (a sodium-glucose cotransporter-2 inhibitor), which is approved for the treatment of HFpEF. This builds on the growing body of evidence supporting the multi-modal mechanism of action that is orthogonal from SGLT2 inhibitors.

Research

•In October 2023, Tenaya published preclinical research in the American Heart Association’s (AHA) journal, Circulation, detailing its initial success in cardiac cellular regeneration utilizing a single AAV vector to deliver specific combinations of genes to reprogram cells in the heart following ischemic injury.

Third Quarter 2023 Financial Highlights

•Cash Position and guidance: As of September 30, 2023, cash, cash equivalents and investments in marketable securities were $128.1 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 September 30, 2023, were $23.1 million. Non-cash stock-based compensation included in R&D expense was $1.9 million for the quarter ended September 30, 2023.

•General & Administrative (G&A) Expenses: G&A expenses for the quarter ended September 30, 2023, were $7.8 million. Non-cash stock-based compensation included in G&A expense was $2.2 million for the quarter ended September 30, 2023.

•Net Loss: Net loss for the quarter ended September 30, 2023, was $29.1 million, or $0.39 per share.
