Tempest Announces Publication of Positive Data from Phase 1 Trial of TPST-1120 in Patients with Advanced Solid Tumors in Journal of Cancer Research Communications

The recent findings on TPST-1120, particularly its efficacy in PD-1 inhibitor refractory and immune compromised cancers, represent a significant advancement in oncology. The ability of this PPARα antagonist to induce tumor shrinkage, as observed in the Phase 1 trial, suggests a potential new line of treatment for patients who have limited options due to resistance to existing therapies. Given the complexity of cancer pathways, the introduction of a novel mechanism that targets a different aspect of tumor biology could improve outcomes for a subset of patients.
Furthermore, the drug's tolerability is a critical factor, as it means that TPST-1120 could be paired with other treatments like nivolumab without exacerbating patient side effects. This could lead to new combination therapies that may enhance the overall effectiveness of cancer treatment regimens. The move into a Phase 3 trial in HCC is an indicator of the drug's promising results and its potential to meet an unmet medical need in a difficult-to-treat cancer population.
The transition of TPST-1120 into a pivotal Phase 3 trial is a testament to its promising clinical activity. The drug's progress through clinical trials has significant implications for stakeholders, including patients, healthcare providers and investors. For patients, particularly those with advanced HCC for whom first-line treatments have failed, TPST-1120 could offer a new therapeutic option. For healthcare providers, it represents an emerging treatment that could be integrated into clinical practice pending further validation.
From an investment perspective, the positive results from early-phase trials could lead to increased investor confidence in Tempest Therapeutics. However, it is essential to note that the success of Phase 1 and Phase 1b/2 trials does not guarantee Phase 3 success due to the larger and more diverse patient population. The long-term impact on the company's stock will depend on the outcome of the Phase 3 trial, regulatory approvals and market reception if the drug reaches commercialization.
The oncology market is highly competitive, with numerous companies vying for a share of the cancer treatment landscape. The positive data on TPST-1120 positions Tempest Therapeutics in a favorable spot within this market, especially in the niche of advanced HCC where treatment options are limited. The drug's success in early trials could attract partnership opportunities, licensing deals, or even make Tempest a potential acquisition target.
It is important to monitor the drug's progress and the company's strategic moves closely, as they will influence the valuation of Tempest Therapeutics. If TPST-1120 proves to be effective in Phase 3 trials, it could lead to significant revenue streams for the company. However, it is also essential to consider the potential risks, such as regulatory hurdles, market competition and the challenges of commercialization, which could impact the drug's success and, consequently, the company's financial health.

BRISBANE, Calif., April 04, 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 that Cancer Research Communications published positive clinical data from the dose-escalation Phase 1 trial of TPST-1120 in an article titled “First-in-Human Phase I Trial of TPST-1120, an inhibitor of PPARα, as Monotherapy or in Combination with Nivolumab, in Patients with Advanced Solid Tumors.” The data showed that TPST-1120 demonstrated clinical activity, including tumor shrinkage, even in PD-1 inhibitor refractory and immune compromised cancers, and was well tolerated both as monotherapy and in combination with nivolumab. These earlier Phase 1 data complement the positive Phase 1b/2 data reported in October 2023 from a global randomized study of TPST-1120 in combination with atezolizumab and bevacizumab in first-line patients with advanced HCC, which showed clinical superiority of the TPST-1120 arm across multiple study endpoints and relevant biomarker-defined patient subpopulations.
“In this Phase 1 study of TPST-1120, we saw the first evidence of anti-tumor activity in multiple cancer types, affirming our belief that PPARα inhibition is an exciting and novel approach for cancer treatment,” said Sam Whiting, M.D., Ph.D., chief medical officer and head of R&D at Tempest. “These early-phase data are supported by the positive top line results of the ongoing randomized Phase 1b/2 trial in first-line HCC. We believe there is tremendous potential for TPST-1120 to make a meaningful impact for patients and we look forward to providing updated data this year.”
About the TPST-1120 Phase 1 Study
In this first-in-human Phase 1 study, 35 patients were treated with escalating doses of TPST-1120 either as monotherapy (20 patients) or in combination with the anti-PD-1 therapy, nivolumab (15 patients). TPST-1120 was well-tolerated as monotherapy and in combination, with a maximum tolerated dose not identified and predominantly low-grade toxicity. Notwithstanding the late-line stage of these patients and difficult to treat tumor types, clinical benefit was observed as both a monotherapy and combination.2 In monotherapy, a best response of stable disease (SD) was observed in
In the combination therapy cohorts, including patients with heavily pretreated cholangiocarcinoma (CCA), hepatocellular carcinoma (HCC) and renal cell carcinoma (RCC), the objective response rate (ORR) was
About TPST-1120
TPST-1120 is an oral, small molecule, selective PPAR⍺ antagonist. Tempest’s data suggest that TPST-1120 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 TPST-1120 in combination with atezolizumab and bevacizumab in first-line patients with advanced HCC, the TPST-1120 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. TPST-1120 is wholly-owned by Tempest.
