• Granted Both Orphan Drug & Fast Track designations for Amezalpat (TPST-1120) for the treatment of patients with Hepatocellular Carcinoma (HCC) • Announced Agreement with Roche to Support Advancement of Amezalpat Combination Therapy into First-Line HCC Pivotal Trial • Received FDA “Study May Proceed” letter for Phase 2 trial of TPST-1495 for the treatment of Familial Adenomatous Polyposis (FAP)
BRISBANE, Calif., March 27, 2025 (GLOBE NEWSWIRE) -- Tempest Therapeutics, Inc. (Nasdaq: TPST), a clinical-stage biotechnology company developing first-in-class1 targeted and immune-mediated therapeutics to fight cancer, today reported financial results for the year ended 2024 and provided a corporate update.
“2024 was another year filled with significant progress and milestone achievements that position Tempest for a successful future,” said Stephen Brady, president and chief executive officer of Tempest. “Despite challenging capital markets, our lean team excelled, reporting key OS data from the ongoing randomized Phase 2 trial of amezalpat in first-line hepatocellular carcinoma. As previously announced, we have secured broad regulatory agreement with both the FDA and EMA on the Phase 3 plan and received both Orphan Drug and Fast Track designations from the FDA. We also advanced our second clinical program, TPST-1495, with a Phase 2 clinical trial for the treatment of patients with FAP, with data expected in 2026. Our focus remains on execution with excellence while securing the resources necessary to drive these promising drug candidates forward.”
2024 & Recent Accomplishments
Amezalpat (TPST-1120) (clinical PPARα antagonist):
Granted both Orphan Drug and Fast Track designations by the U.S. Food and Drug Administration (FDA) for amezalpat for the treatment of patients with HCC. Received a “Study May Proceed” letter from the FDA to evaluate amezalpat in combination with atezolizumab (TECENTRIQ®) and bevacizumab (Avastin®), the current standard of care for unresectable or metastatic HCC, in a pivotal Phase 3 trial for the first-line treatment of unresectable or metastatic HCC. Announced an agreement with F. Hoffmann-La Roche Ltd. (Roche) to advance the evaluation of amezalpat in combination with atezolizumab and bevacizumab into a pivotal Phase 3 trial for the first-line treatment of unresectable or metastatic HCC. Announced positive feedback from the end-of-Phase 2 meeting with the FDA for amezalpat in combination with atezolizumab and bevacizumab to treat first-line unresectable or metastatic HCC. Reported new positive survival data from the ongoing global randomized Phase 1b/2 clinical study demonstrating that amezalpat delivered a six-month improvement in median overall survival (OS) when combined with atezolizumab and bevacizumab in comparison to atezolizumab and bevacizumab alone, the standard of care, in the first-line treatment of patients with unresectable or metastatic HCC. Published positive data from Phase 1 trial of amezalpat in patients with advanced solid tumors in the Journal of Cancer Research Communications. Data showed that amezalpat demonstrated clinical activity, including tumor shrinkage, even in PD-1 inhibitor-refractory and immune-compromised cancers. These data complement the positive Phase 1b/2 data reported in October 2023 and June 2024 from a global randomized study of amezalpat in combination with atezolizumab and bevacizumab in first-line patients with advanced HCC. Reported new preclinical data at the 2024 American Association for Cancer Research (AACR) Annual Meeting demonstrating that amezalpat reduces kidney cancer growth as a monotherapy, while also showing increased inhibition when combined with frontline chemotherapy and immunotherapy. These data further support the clinical benefit observed in the amezalpat Phase 1 data presented in an oral presentation at ASCO 2022.
TPST-1495 (clinical dual EP2/4 prostaglandin receptor antagonist) Received a “Study May Proceed” letter from the FDA to evaluate TPST-1495 in a Phase 2 Trial for the treatment of FAP. Corporate: Expanded leadership team to strengthen global clinical expertise with the appointments of Troy M. Wagner as Vice President of Quality Assurance and Sheldon Mullins as Vice President of Regulatory Affairs.

Potential Future Milestones
Amezalpat (TPST-1120) (clinical PPARα antagonist) Plan to advance amezalpat into a registrational study in first-line liver cancer patients, subject to obtaining additional resources. TPST-1495 (clinical dual EP2/4 prostaglandin receptor antagonist) Plan to advance TPST-1495 into a Phase 2 study in patients with FAP under the auspices of the Cancer Prevention Clinical Trials Network and funded by the National Cancer Institute (NCI) Division of Cancer Prevention in 2025, with data expected in 2026.

Financial Results
Year End 2024
Tempest ended the year with $30.3 million in cash and cash equivalents, compared to $39.2 million on December 31, 2023. The decrease was primarily due to cash used in operating activities, offset by proceeds from the issuance of common stock of $28.6 million from the at-the-market offering program. Net loss and net loss per share for the year were $41.8 million and $1.50, respectively, compared to $29.5 million and $1.91, respectively, for the same period in 2023. Research and development expenses for the year were $28.5 million compared to $17.5 million for the same period in 2023. The $11.0 million increase was primarily due to an increase in costs incurred from engaging contract research and manufacturing organizations in preparation for our pivotal Phase 3 trial of amezalpat for the treatment of first-line HCC. General and administrative expenses for the year were $13.6 million compared to $11.7 million for the same period in 2023. The $1.9 million increase was primarily due to an increase in stock-based compensation expense due to increased headcount as well as an increase in expenses related to legal and consulting services.
