Detailed Summary

This phase Ib trial tests the safety, side effects, and best dose of M1774 when given with ZEN-3694 in treating patients with ovarian and endometrial cancer that has come back (recurrent). M1774 and ZEN-3694 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. M1774 and ZEN-3694 combined together has demonstrated to be better than either drug alone in killing ovarian tumor cells.

Arms & Interventions

Treatment (tuvusertib, BET bromodomain inhibitor ZEN-3694)experimental

Patients receive tuvusertib PO QD either on days 2-14 of cycle 1 and days 1-14 of subsequent cycles or days 1-14 of each cycle and BET bromodomain inhibitor ZEN-3694 PO QD on days 1-28 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients in the dose-escalation phase of the trial also undergo collection of blood samples on study, and x-ray, CT, or MRI throughout the trial. Patients in the dose-expansion phase of the trial also undergo biopsies during screening and on study, and x-ray, CT, or MRI, and collection of blood samples throughout the trial.
