Tempest Presents Data Showing TPST-1120-Induced Pharmacodynamic Changes Consistent with Clinical Benefit Observed in Patients with Cancer
- TPST-1120 Late-breaking Poster Presentation at SITC Annual Meeting
- Second Poster Presentation Demonstrates that Dual Blockade of EP2 and EP4 PGE2 Receptors with TPST-1495 is an Optimal Approach for Drugging the Prostaglandin Pathway
Excerpt from the Press Release:
SOUTH SAN FRANCISCO, Calif., Nov. 10, 2022 (GLOBE NEWSWIRE) — Tempest Therapeutics, Inc. (Nasdaq: TPST), a clinical-stage oncology company focused on developing first-in-class therapeutics that combine both targeted and immune-mediated mechanisms, today announced the presentation of data on TPST-1120, an oral selective peroxisome-proliferator activated receptor-alpha (PPAR-α) antagonist, and TPST-1495, a dual antagonist of both EP2 and EP4 prostaglandin (PGE2) receptors, at the Society for Immunotherapy of Cancer (SITC) 37th Annual Meeting taking place November 10-12, 2022 in Boston, MA.
The biomarker results presented from the TPST-1120 Phase 1 clinical study demonstrate pharmacodynamic changes in circulating blood in patients who received clinical benefit from therapy that are consistent with blocking the activity of PPAR-α. In addition, data presented from TPST-1495 showed that its dual antagonism of EP2 and EP4 generated significantly greater immune activation in human immune cells and anticancer activity in mouse tumor models than single inhibitors of either receptor, or the COX-2 inhibitor, celecoxib.
“As we advance the Tempest pipeline, we continue to generate results that validate and differentiate the novel approaches of our product candidates,” said Tom Dubensky, Ph.D., president of Tempest. “For patients who responded to treatment with TPST-1120 in our Phase 1 study, we have identified potential biomarkers in the peripheral blood of immune activation and alleviation of immune suppression. These discoveries may enable us to identify patient populations in future clinical studies that are most likely to benefit from treatment with TPST-1120.”
