Study of the Drug Sovilnesib in People with Ovarian Cancer

About the Study

This study will test the safety and effectiveness of the drug sovilnesib in patients with ovarian cancer. The study will be divided into two parts.

Part 1: 10 people will be assigned at random to receive different dose levels of the drug sovilnesib. Sovilnesib is a drug in pill form and is taken by mouth.

Part 2: 20 to 30 people will be assigned at random to receive two or more dose levels of the drug sovilnesib by mouth.

What the Study Involves

People in the study will take sovilnesib orally in 28-day cycles. They will continue to receive the medication until the treatment stops working, causes serious side effects, or they do not wish to continue with the treatment.
