Summary

This phase II trial tests whether adding the immunotherapy tremelimumab to the PARP inhibitor olaparib works better than olaparib alone for women with platinum-sensitive recurrent ovarian, fallopian tube, or peritoneal cancer. About 61 participants will receive either olaparib alone or olaparib plus tremelimumab. The study measures how long the cancer stays under control and any side effects.

Active substance

olaparib and tremelimumab

What this could lead to

If successful, this combination could offer a more effective treatment option for women with recurrent ovarian cancer that responds to platinum-based therapy.

What could go wrong

This is a small, early-phase trial (61 participants) testing safety and effectiveness. The combination may cause more side effects and may not improve outcomes over olaparib alone.
