If You Invested in Tempest Therapeutics Inc (TPST)

Tempest Therapeutics, Inc. (NASDAQ: TPST) is a clinical-stage biotechnology company focused on developing small molecule therapeutics with tumor-targeted and immune-mediated mechanisms to fight cancer. According to the company’s disclosures, its programs span from early research to later-stage clinical investigation in first-line cancer patients, and its product candidates are designed with the potential to treat a wide range of tumors. Tempest is headquartered in Brisbane, California.

The company describes itself as advancing a diverse portfolio of small molecule product candidates that act through tumor-targeted and/or immune-mediated mechanisms. This approach is reflected in its clinical pipeline, which includes amezalpat (TPST-1120) and TPST-1495, as well as additional programs referenced in company communications. Tempest’s programs are positioned in oncology indications where there is significant unmet medical need, including hepatocellular carcinoma (HCC) and familial adenomatous polyposis (FAP).

Core Oncology Programs

Amezalpat (TPST-1120) is described by Tempest as an oral, small molecule, selective PPAR⍺ antagonist. Company materials state that data suggest amezalpat treats cancer by targeting tumor cells directly and by modulating immune suppressive cells and angiogenesis in the tumor microenvironment. In a global randomized Phase 1b/2 study in first-line advanced HCC, Tempest reports that the amezalpat combination arm showed clinical superiority across multiple study endpoints, including overall survival in both the entire population and key subpopulations, compared with standard-of-care atezolizumab and bevacizumab alone.

Tempest has also reported that amezalpat has received regulatory designations. According to company press releases, the U.S. Food and Drug Administration has granted Orphan Drug and Fast Track designations for amezalpat for the treatment of patients with HCC, and the European Medicines Agency has granted Orphan Drug Designation for the same indication. The company further notes that regulatory authorities in the United States, Europe and China have provided clearances or agreements related to a planned pivotal Phase 3 study of amezalpat in first-line unresectable or metastatic HCC in combination with standard-of-care therapy.

TPST-1495 is described as a clinical dual EP2/4 prostaglandin receptor antagonist and a novel dual receptor inhibitor of prostaglandin (PGE2) signaling. Tempest reports that the FDA has granted Orphan Drug Designation to TPST-1495 for the treatment of patients with familial adenomatous polyposis. Company disclosures also state that a Phase 2 trial in FAP is planned to be conducted by the Cancer Prevention Clinical Trials Network and supported by the National Cancer Institute’s Division of Cancer Prevention, with Tempest having received a “Study May Proceed” letter from the FDA for this study.

Expansion into Cell Therapy and Dual-CAR T Programs

In an asset purchase agreement described in a Form 8-K filing, Tempest agreed to acquire certain dual-targeting chimeric antigen receptor (CAR) T-cell therapy programs from Factor Bioscience Inc. and an affiliated entity. The assets include autologous and allogeneic dual-targeting CAR T-cell therapies directed at BCMA/CD19 and CD70/CD70, referred to in the agreement as ERI-2003, ERI-2206, ERI-3003 and ERI-3206. In a related press release, Tempest indicates that the acquired clinical-stage CD19/BCMA dual-CAR T program is referred to as TPST-2003 and is intended to expand and further diversify its existing clinical-stage pipeline.

The company has also referenced additional preclinical and research-stage programs, including dual-targeting CAR-T candidates such as TPST-2206, TPST-3003 and TPST-3206, in its public communications. These programs are described as part of Tempest’s effort to build a broader oncology pipeline that includes both small molecules and cell therapy approaches.

Regulatory and Clinical Development Focus

Tempest’s public statements emphasize its focus on first-line cancer settings and advanced solid tumors. For amezalpat, the company highlights randomized clinical data in first-line advanced HCC, including outcomes in patients with markers of immune resistance. For TPST-1495, Tempest underscores the unmet need in FAP, a high-risk inherited syndrome with no approved medical therapies, and notes that its planned Phase 2 study is intended to address cancer prevention in a high-risk population.

In multiple press releases, Tempest notes that its programs have attracted regulatory interest through designations such as Orphan Drug and Fast Track, and through clearances or agreements for pivotal or registration-directed trials. The company also describes presenting mechanism-of-action data for amezalpat at major scientific meetings, including the American Association for Cancer Research Annual Meeting, to support the immune component of its proposed dual mechanism of action.

Corporate and Capital Markets Activity

Tempest Therapeutics’ common stock trades on The Nasdaq Stock Market under the symbol TPST. The company has disclosed several capital-raising transactions, including registered direct offerings of common stock and concurrent private placements of warrants, conducted under an effective shelf registration statement on Form S-3.
