ClinConnect Summary

This clinical trial is looking at a new treatment approach for women with recurrent ovarian cancer that does not respond to platinum-based chemotherapy. The researchers want to find out how well a combination of two drugs, adebrelimab and fuzuloparib, works in this situation. The trial is currently recruiting participants aged between 18 and 70 who have experienced their cancer returning within six months after their last platinum treatment. To qualify, participants must have a specific type of ovarian cancer confirmed by a doctor and must have certain genetic markers and health conditions.

Participants in the trial will receive the combination treatment and will be closely monitored for both effectiveness and safety. They will need to meet specific health criteria, including having normal blood tests and no severe heart or lung issues. Women who can become pregnant will need to confirm they are not pregnant and agree to use contraception during the study. This trial could potentially provide new options for women whose cancer has proven difficult to treat, and participants will have the chance to contribute to important research in this area.
