Tenaya Therapeutics Reports Fourth Quarter and Full Year 2023 Financial Results and Provides Business Update


Initial Data from Ongoing MyPeak™-1 Phase 1b of TN-201 for MYBPC3-associated HCM Expected in Second Half of 2024

On Track to Dose First Patient in RIDGE™-1Phase 1b Clinical Trial of TN-401 for
PKP2-associated ARVC in Second Half 2024

$47 Million Net Proceeds from Recent Financing Extends Cash Runway into
Second Half of 2025

SOUTH SAN FRANCISCO, Calif., March 18, 2024 -- 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 for the fourth quarter and full year ended December 31, 2023, and provided a corporate update.

“Tenaya had a successful year of sustained execution in 2023 that meaningfully advanced our portfolio of genetic medicines for heart disease. We announced IND clearance for the TN-201 and TN-401 gene therapy programs; activated clinical trial sites in the USA, Canada, and Europe; dosed the first patient with TN-201; manufactured sufficient clinical trial material for both gene therapy programs at our own cGMP facility; and presented compelling preclinical data from our gene editing and capsid engineering efforts,” said Faraz Ali, Chief Executive Officer of Tenaya. “We look forward to focusing efforts in 2024 on generating early clinical data with TN-201 from the MyPeak-1 study and on initiating patient dosing with TN-401 in the RIDGE-1 study.”

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

In October 2023, the first patient was dosed in the MyPEAK-1 Phase 1b clinical trial of TN-201 for the treatment of Myosin Binding Protein C3 (MYBPC3)-associated HCM. MyPEAK-1 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.
Tenaya anticipates sharing initial safety, biopsy and biomarker data from the first cohort of patients in MyPEAK-1 trial in the second half of 2024.
Tenaya is conducting two non-interventional studies to support the development of TN-201: MyClimb, a natural history study of pediatric patients with MYBPC3-associated HCM and a



study evaluating seroprevalence to adeno-associated virus serotype 9 (AAV9) antibodies among adults with MYBPC3-associated HCM.
In October 2023, Tenaya shared interim results indicating that a majority of MYBPC3-associated HCM patients could be eligible for TN-201 treatment due to low levels of preexisting neutralizing antibodies to AAV9.

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

Tenaya is on track to begin dosing in the RIDGE-1 Phase 1b clinical trial of TN-401 in the second half of 2024. RIDGE-1 is a multicenter, open-label, dose-escalation trial designed to assess safety, tolerability and clinical efficacy of a one-time intravenous infusion of TN-401 for the treatment of ARVC caused by mutations to the Plakophilin-2 (PKP2) gene.
In November, TN-401 received Fast Track Designation from the FDA.
Tenaya is currently conducting a global, non-interventional seroprevalence and natural history study (RIDGE™) enrolling adult PKP2-associated ARV patients.

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

At the 2023 Heart Failure Society of America Annual Scientific Meeting in October 2023, Tenaya shared positive clinical and preclinical data for its small molecule HDAC6 inhibitor program, TN-301.
Results from a Phase 1 dose-escalation study demonstrated that TN-301 was generally well tolerated across the broad range of doses studied. Pharmacokinetic (PK) results showed overall dose proportionality in the single- and multiple-ascending dose stages of the study with a half-life supportive of once-daily dosing. Robust HDAC6 inhibition was observed and increasing doses and exposures with TN-301 correlated with increased pharmacodynamic effects.
New preclinical results demonstrated that the combination of Tenaya’s HDAC6 inhibitor with empagliflozin (a sodium-glucose cotransporter-2 inhibitor) achieved additive benefits in validated HFpEF mouse models compared to either compound alone.

Follow-on Financing

In February 2024, Tenaya completed a follow-on offering with net proceeds of $46.5 million after discounts, commissions, and other offering expenses. The offering consisted of approximately 8.89 million shares of common stock priced at $4.50 per share and, in lieu of common stock for one investor, pre-funded warrants to purchase up to an aggregate of approximately 2.2 million shares at a price of $4.499 per pre-funded warrant. The offering included participation from new and existing investors, The Column Group, RA Capital Management, Venrock Healthcare Capital Partners, Octagon Capital, funds and accounts managed by BlackRock, Armistice Capital, Integral Health Asset Management, PFM Health Sciences, LP and Soleus Capital.

Fourth Quarter and Full Year 2023 Financial Highlights

Cash Position and Guidance: As of December 31, 2023, cash, cash equivalents and investments in marketable securities were $104.6 million. Tenaya expects these funds, combined with net proceeds of $46.5 million from the recent financing, will be sufficient to fund the company into the second half of 2025.



Research & Development (R&D) Expenses: R&D expenses were $22.9 million for the fourth quarter and $98.0 million for the full year ended December 31, 2023. Non-cash stock-based compensation included in R&D expense was $1.8 million for the fourth quarter and $7.0 million for the full year ended December 31, 2023.
General & Administrative (G&A) Expenses: G&A expenses were $8.6 million for the fourth quarter and $33.2 million for the full year ended December 31, 2023. Non-cash stock-based compensation included in G&A expense was $2.1 million for the fourth quarter and $8.3 million for the full year ended December 31, 2023.
Net Loss: Net loss was $29.9 million, or $0.40 per share for the fourth quarter ended December 31, 2023. For the full year 2023, net loss was $124.1 million, or $1.68 per share.
