• Exclusive rights to novel oncology target in-licensed from the lab of Russell Vance, Ph.D., at the University of California at Berkeley ("U.C. Berkeley")

SOUTH SAN FRANCISCO, Calif., Nov. 10, 2021 (GLOBE NEWSWIRE) -- Tempest Therapeutics, Inc. (NASDAQ:TPST), a clinical-stage oncology company developing potentially first-in-class therapeutics that combine both targeted and immune-mediated mechanisms, today reported financial results and provided a corporate update for the third quarter ended September 30, 2021.

"The third quarter of 2021 saw continued execution and progress in our programs, including the opening of a collaborative clinical trial with Roche in first line HCC patients comparing TPST-1120 in combination with atezolizumab and bevacizumab to the standard of care regimen, atezolizumab and bevacizumab," said Stephen R. Brady, chief executive officer of Tempest. "In the fourth quarter of this year and the first half of 2022, we plan to continue this focused approach as our second clinical program, TPST-1495, is poised to move into a set of studies that select patients predicated on strong mechanistic rationale, genetically-defined histologies, and a potential mutation-based biomarker."

Recent Highlights

• TPST-1495 (clinical dual EP2/4 prostaglandin receptor antagonist): continued enrollment in monotherapy dose optimization towards recommended Phase 2 dose ("RP2D").
• TPST-1120 (clinical PPARα antagonist): (i) after completion of monotherapy dose escalation, continued enrollment in combination dose escalation towards RP2D; and (ii) commencement of first line, randomized global Phase 1b/2 study in HCC patients, under a collaboration with F. Hoffmann La Roche.

Financial Results

Third Quarter

• Tempest ended the third quarter of 2021 with $59.8 million in cash and cash equivalents and short-term restricted cash, compared to $18.8 million in December 31, 2020. The increase was primarily due to the merger and concurrent PIPE, which closed in June 2021.
• Net loss and net loss per share for the third quarter of 2021 were $8.1 million and $1.21, respectively, compared to $5.4 million and $11.22, respectively, for the third quarter of 2020. The increase was primarily due to an increase in compensation expense and professional fees associated with the merger.
• Research and development expenses for the third quarter of 2021 were $4.6 million, compared to $4.3 million for the same period in 2020. The $0.3 million increase was primarily attributable to increased outside services, insurance and compensation expenses.
• For the three months ended September 30, 2021, general and administrative expenses were $3.1 million compared to $1.2 million for the same period in 2020. The increase was primarily due to growth in compensation and rent expense, as well as professional fees associated with the merger.

Year-to-Date

• Net cash used in operations for the nine months ended September 30, 2021 was $18.0 million.
• Net loss and net loss per share for the nine months ended September 30, 2021 were $20.5 million and $7.49, respectively, compared to $14.9 million and $31.91, respectively, for the same period in 2020.
• Research and development expenses for the nine months ended September 30, 2021 were $12.5 million compared to $11.4 million for the same period in 2020. The $1.1 million increase was primarily due to increased compensation expenses and consulting services.
• For the nine months ended September 30, 2021, general and administrative expenses were $7.2 million compared to $3.6 million for the same period in 2020.
• Based on current cash position and operating plan, Tempest expects to have sufficient resources to fund operations into the second quarter of 2023.
