Amezalpat (TPST-1120) is Phase 3-ready: completed FDA and EMA interactions for first-line pivotal study in hepatocellular carcinoma (HCC); global investigator support in place Awarded both Orphan Drug & Fast Track designations for amezalpat based on positive randomized Phase 2 data in first-line HCC Received FDA “Study May Proceed” letter for TPST-1495 in a Phase 2 trial for the treatment of familial adenomatous polyposis (FAP); data expected 2026 BRISBANE, Calif., April 09, 2025 (GLOBE NEWSWIRE) -- Tempest Therapeutics, Inc. (Nasdaq: TPST), a clinical-stage biotechnology company developing first-in-classi targeted and immune-mediated therapeutics to fight cancer, today announced that the company plans to explore a full range of strategic alternatives to advance its promising clinical stage programs and maximize stockholder value. Strategic alternatives under consideration may include, but are not limited to, mergers, acquisition, partnerships, joint ventures, licensing arrangements or other strategic transactions. The company has retained MTS Health Partners, L.P., an internationally recognized financial advisor with substantial experience in the biotechnology industry, to support it with the strategic evaluation process. “Notwithstanding the positive randomized data set from the amezalpat Phase 2 and its blockbuster potential in first-line HCC, as well as the potential of TPST-1495 as it moves towards a Phase 2 in FAP, the capital markets have been unavailable to support the next stage of advancement,” said Stephen Brady, president and chief executive officer of Tempest. “We are initiating a process to explore alternatives available to the company to maximize stockholder value, which include finding a strategic partner with the resources to develop what we believe are potentially life-saving therapies for patients in need. Given the positive data and commercial potential with this pipeline, as well as the clearance from FDA on the lead program’s pivotal study, we believe this is a rare opportunity for a partner.” The company has not set a timetable for completion of the process for evaluating strategic alternatives and does not intend to disclose further developments or guidance on the status of its programs or the process for evaluating strategic alternatives unless and until it is determined that further disclosure is appropriate or necessary. No agreement providing for any transaction has been reached and there can be no assurances that any transaction will result from the process for evaluating strategic alternatives. If the process for evaluating strategic alternatives results in an agreement regarding a transaction, there can be no assurances that any transaction will be completed. Program Milestones and Status 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 the 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 reduced kidney cancer growth as a monotherapy, while also showing increased inhibition when combined with frontline chemotherapy and immunotherapy. TPST-1495 (clinical dual EP2/4 prostaglandin receptor antagonist): Granted Orphan Drug designation by the FDA for TPST-1495 for the treatment of patients with FAP. Received a “Study May Proceed” letter from the FDA to evaluate TPST-1495 in a Phase 2 trial for the treatment of FAP. About Amezalpat (TPST-1120) Amezalpat is an oral, small molecule, selective PPAR⍺ antagonist. Data suggest that amezalpat treats cancer by targeting tumor cells directly and by modulating immune suppressive cells and angiogenesis in the tumor microenvironment. In an ongoing global randomized Phase 1b/2 study of amezalpat in combination with atezolizumab and bevacizumab in first-line patients with advanced HCC, the amezalpat arm showed clinical superiority across multiple study endpoints, including overall survival in both the entire population and key subpopulations, when compared to atezolizumab and bevacizumab alone, the standard of care. These randomized data were supported by additional positive results observed in the Phase 1 clinical trial in patients with heavily pretreated advanced solid tumors, including renal cell carcinoma and cholangiocarcinoma. About TPST-1495 TPST-1495 is a novel, highly selective and potent EP2-EP4 dual antagonist designed to block the cancer-promoting EP2 and EP4 receptors in the prostaglandin (PGE2) pathway, while sparing the homologous but differentially active EP1 and EP3 receptors. PGE2 signaling through EP2 and EP4 has been observed to enhance tumor progression through the stimulation of tumor proliferation, enhanced angiogenesis and suppression of immune function in the tumor microenvironment. The Phase 2 study of TPST-1495 in patients with FAP is expected to begin in 2025 under the auspices of the Cancer Prevention Clinical Trials Network and funded by the National Cancer Institute (NCI) Division of Cancer Prevention. About Tempest Therapeutics Tempest Therapeutics is a clinical-stage biotechnology company advancing a diverse portfolio of small molecule product candidates containing tumor-targeted and/or immune-mediated mechanisms with the potential to treat a wide range of tumors. The company’s novel programs range from early research to later-stage investigation in a randomized global study in first-line cancer patients. Tempest is headquartered in Brisbane, California.
