"The positive data and mechanistic analysis presented in the first quarter build on the positive preclinical and clinical data package for TPST-1120, further confirming and reinforcing our excitement about the potential of TPST-1120 in liver and kidney cancers, as well as other indications, and our confidence in the program as it moves closer to a pivotal Phase 3 study in first-line HCC," said Stephen Brady, president and chief executive officer of Tempest.

Recent Highlights

TPST-1120 (clinical PPARα antagonist):
Reported new preclinical data at the 2024 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting demonstrating that TPST-1120 reduces kidney cancer (RCC) 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 TPST-1120 Phase 1 data presented in an oral presentation at ASCO (Free ASCO Whitepaper) 2022.
Published positive data from Phase 1 Trial of TPST-1120 in patients with advanced solid tumors in the Journal of Cancer Research Communications. 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 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.
Presented new preclinical data showing potent anti-tumor activity in several cancer models treated with TPST-1120 alone or with immune checkpoint inhibitors at the Society for Immunotherapy of Cancer (SITC) (Free SITC Whitepaper) 2024 Spring Scientific Meeting. The presentation also covered experimental results that corroborated clinical biomarker data from patients with advanced solid tumor cancers treated in the Phase 1 clinical trial of TPST-1120 in multiple solid tumor indications, which showed statistically significant, exposure-dependent elevations in expression levels of multiple immune-related genes, and patients exhibiting objective responses displayed increased circulating free fatty acids (FFA), both of which are in-line with the proposed TPST-1120 mechanism of action.
Potential Future Milestones

TPST-1120 (clinical PPARα antagonist)
Expect to announce updated data from the ongoing randomized study in first-line HCC patients in 2024.
Plan to advance TPST-1120 into a registrational Phase 3 study in first-line HCC patients, subject to obtaining feedback from the FDA.
TPST-1495 (clinical dual EP2/4 prostaglandin receptor antagonist)
Plan to advance TPST-1495 into a Phase 2 study in patients with Familial Adenomatous Polyposis ("FAP") in 2024 under the auspices of the Cancer Prevention Clinical Trials Network and funded by the National Cancer Institute ("NCI") Division of Cancer Prevention, subject to final approval of NCI.
Expect to report data from the combination arm at the two highest TPST-1495 doses in patients with advanced endometrial cancer, where prostaglandin signaling is implicated, in 2024.
Financial Results

First Quarter 2024

Tempest ended the quarter with $32.3 million in cash and cash equivalents, compared to $39.2 million on December 31, 2023.
Net loss and net loss per share for the quarter ended March 31, 2024, were $7.9 million and $0.36, respectively, compared to $7.6 million and $0.55, respectively, for the same period in 2023.
Research and development expenses for the quarter were $4.3 million compared to $4.7 million for the same period in 2023. The $0.4 million decrease was primarily due to a decrease in costs incurred from contract research organizations and third-party vendors.
General and administrative expenses for the quarter were $3.6 million compared to $2.9 million for the same period in 2023. The $0.7 million increase was primarily due to share-based compensation expenses and consulting services.
Based on its current cash and operating plan, Tempest expects to have sufficient resources to fund operations into the second quarter of 2025.
