SAN DIEGO, May 05, 2026 (GLOBE NEWSWIRE) — Zentalis® Pharmaceuticals, Inc. (Nasdaq: ZNTL), a clinical oncology innovator advancing late-stage development of investigational first-in-class WEE1 inhibitor azenosertib as a biomarker-driven treatment approach for ovarian cancer, today announced that the first patient has been dosed in the Phase 3 ASPENOVA clinical trial (NCT07546500, GOG-3147, ENGOT-ov109, APGOT-OV27) evaluating azenosertib in patients with Cyclin E1-positive platinum-resistant ovarian cancer (PROC).
“Dosing the first patient in the ASPENOVA Phase 3 clinical trial represents a significant milestone in our development of azenosertib for patients with platinum-resistant ovarian cancer,” said Ingmar Bruns, M.D., Chief Medical Officer of Zentalis. “With DENALI Part 2 progressing toward a year-end readout that may support accelerated approval and ASPENOVA now enrolling to evaluate azenosertib versus standard-of-care chemotherapy to support full approval, we are executing on a comprehensive development and regulatory strategy designed to bring this therapy to patients as quickly as possible. We are deeply grateful to the patients participating in this important trial and to our collaborators at The GOG Foundation, Inc. (GOG-F), ENGOT, and APGOT for their partnership in advancing this research.”
