This is a randomized, Phase 3 trial designed to evaluate the efficacy and safety of azenosertib compared to Investigator's choice of chemotherapy in subjects with platinum-resistant ovarian cancer whose tumors are positive for cyclin E1 protein expression.
A Phase 3 study to evaluate the efficacy, safety, and overall clinical benefit of azenosertib (ZN-c3) compared with Investigator's choice of chemotherapy in subjects with Platinum-Resistant, High-Grade Serous Ovarian, Fallopian Tube, or Primary Peritoneal Cancer. Azenosertib is a selective and orally bioavailable inhibitor of WEE1. In HGSOC, high Cyclin E1 protein drives replication stress and increases tumor reliance on WEE1-mediated G2/M checkpoint control. Treating tumor cells with azenosertib promotes premature cell cycle progression leading to increased replication stress and accumulation…
