Summary

This trial is testing a new combination drug treatment for women with ovarian cancer that has stopped responding to other treatments.

Who is the study for?
This trial is for women aged 18+ with high-grade ovarian, peritoneal, or fallopian tube cancer that's resistant to platinum therapy. They must have relapsed within 6 months of treatment and be willing to provide tissue samples. Participants need measurable disease and good organ function but can't join if they have certain heart conditions, uncontrolled blood pressure, gastrointestinal issues affecting absorption, a history of MDS/AML or are on drugs with TdP risk.Check my eligibility
What is being tested?
The study tests ZN-c3 alone and combined with niraparib in patients with platinum-resistant ovarian cancer. It aims to assess the safety and effectiveness of these treatments while also studying how the body processes them (pharmacokinetics) and their impact on the disease at a cellular level (pharmacodynamics).See study design
What are the potential side effects?
Potential side effects may include typical reactions from anticancer medications such as nausea, fatigue, low blood counts leading to increased infection risk or bleeding tendencies. Specific side effects related to ZN-c3 or niraparib could emerge during the trial.
