Tempest Announces Successful End-of-Phase 2 Meeting with FDA for Amezalpat (TPST-1120) to Treat First-Line Hepatocellular Carcinoma
Tempest Therapeutics (Nasdaq: TPST) announced a successful end-of-Phase 2 meeting with the FDA for amezalpat (TPST-1120) in treating first-line hepatocellular carcinoma (HCC). The FDA and Tempest reached broad agreement on the pivotal Phase 3 study plan, including:
1. Using the current amezalpat dose and schedule
2. Setting overall survival as the primary endpoint
3. Implementing an early efficacy analysis that could significantly reduce time to primary read-out
The planned Phase 3 study closely mirrors the randomized Phase 2 study, which showed a strongly favorable hazard ratio for overall survival. This outcome gives Tempest confidence in the potential success of the Phase 3 trial for amezalpat in combination with atezolizumab and bevacizumab for first-line unresectable or metastatic HCC.

Tempest Therapeutics (Nasdaq: TPST) gab bekannt, dass das Ende der Phase-2-Sitzung mit der FDA für amezalpat (TPST-1120) bei der Behandlung von hepatozellulärem Karzinom (HCC) in der ersten Linie erfolgreich war. Die FDA und Tempest einigten sich umfassend auf den Plan für die Phase-3-Studie, der Folgendes umfasst:
1. Verwendung der aktuellen Dosis und des Zeitplans von amezalpat
2. Festlegung der Gesamtüberlebensrate als primäres Ziel
3. Durchführung einer frühen Wirksamkeitsanalyse, die die Zeit bis zur primären Auswertung erheblich verkürzen könnte
Die geplante Phase-3-Studie spiegelt die randomisierte Phase-2-Studie wider, die ein stark günstiges Hazard-Verhältnis für das Gesamtüberleben zeigte. Dieses Ergebnis gibt Tempest Zuversicht in das potenzielle Gelingen der Phase-3-Studie für amezalpat in Kombination mit Atezolizumab und Bevazizumab bei unresezierbarem oder metastatischem HCC in der ersten Linie.
- FDA agreement on Phase 3 study design, including control arm and endpoints
- Approval to use current amezalpat dose and schedule in Phase 3
- Agreement on statistical plan with early efficacy analysis, potentially shortening time to primary analysis by up to 8 months
- Strong overall survival results from Phase 2 trial, confirmed in latest follow-up
- None.
The FDA's agreement on the Phase 3 study design for amezalpat in first-line HCC treatment is a significant milestone for Tempest Therapeutics. The confirmation of overall survival as the primary endpoint is particularly noteworthy, as it's the gold standard for oncology trials. The agreed-upon early efficacy analysis could potentially accelerate the drug's path to market by up to 8 months, which is important in the competitive oncology landscape.
The favorable hazard ratio for overall survival observed in the Phase 2 trial is a strong indicator of amezalpat's potential efficacy. However, it's important to note that Phase 3 trials often yield different results than earlier studies. The agreement on the current dose and schedule suggests a good safety profile, which is essential for combination therapies in cancer treatment.
The development of amezalpat for first-line HCC treatment is promising. HCC is a challenging cancer with treatment options and the current standard of care (atezolizumab plus bevacizumab) has room for improvement. The triple combination of amezalpat with atezolizumab and bevacizumab could potentially enhance efficacy without significantly increasing toxicity, given the FDA's agreement on the current dose.
The focus on overall survival as the primary endpoint is clinically relevant and aligns with what we, as oncologists, value most in patient care. If successful, this trial could lead to a new first-line standard of care for HCC patients, potentially improving outcomes in this difficult-to-treat population. However, we must await the Phase 3 results to confirm the promising Phase 2 data.
Tempest Therapeutics' successful end-of-Phase 2 meeting with the FDA is a positive development for the company. The agreement on the Phase 3 trial design, including the potential for early efficacy analysis, could accelerate the timeline for amezalpat's potential market entry. This is important for a small biotech company, as it could lead to earlier revenue generation and potentially attract partnership or acquisition interest.
However, investors should note that Tempest still faces significant challenges. The company will need substantial funding to conduct the Phase 3 trial and success is not guaranteed. The HCC market is competitive, with several large pharmaceutical companies already present. While positive Phase 3 results could significantly boost Tempest's value, the company remains a high-risk, high-reward investment typical of early-stage biotech firms.
- Broad agreement on pivotal Phase 3 study plan, including use of current amezalpat dose and schedule
- Overall survival, the strongest result from the Phase 2 trial, will be the primary study endpoint
- Agreed-upon early efficacy analysis could reduce time to primary read-out significantly
BRISBANE, Calif., Aug. 15, 2024 (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 positive feedback from its end-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) for amezalpat (TPST-1120) in combination with atezolizumab and bevacizumab to treat first-line unresectable or metastatic hepatocellular carcinoma (HCC).
"We are thrilled with the positive outcome of our end-of-Phase 2 meeting with the FDA,” said Sam Whiting, M.D., Ph.D., chief medical officer and head of R&D at Tempest. “Tempest and the FDA are in broad agreement on all major aspects of the proposed pivotal Phase 3 clinical trial for amezalpat in patients with hepatocellular carcinoma in the first line setting. This planned Phase 3 study closely mirrors the randomized Phase 2 study and the strongly favorable hazard ratio for overall survival observed at top-line analysis of the Phase 2, confirmed at the latest survival follow-up, give us confidence in the potential success of the Phase 3.”
Key outcomes of the FDA meeting include:
- Agreement on Phase 3 study design, including the standard-of-care control arm and the primary and secondary study endpoints
- Agreement on appropriateness of the current amezalpat dose and schedule for the Phase 3 study
- Agreement on the Phase 3 statistical plan including a pre-specified early efficacy analysis that the company currently estimates could shorten the time to primary analysis by up to 8 months
About the TPST-1120-301 Study
The planned Phase 3 study is a global, blinded, 1:1 randomized study of amezalpat plus atezolizumab and bevacizumab vs. atezolizumab and bevacizumab, the standard of care, in patients with unresectable or metastatic HCC treated in the first line setting. The company is preparing for the Phase 3 study start in the first quarter of 2025.
About Amezalpat (TPST-1120)
Amezalpat is an oral, small molecule, selective PPAR⍺ antagonist. Tempest’s 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 when compared to atezolizumab and bevacizumab alone, the standard of care. These randomized data were supported by positive results observed in the Phase 1 clinical trial in patients with heavily pretreated advanced solid tumors.
