First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 2 trial is testing whether adding oregovomab (an antibody) to niraparib (a daily pill) can better control platinum-sensitive recurrent ovarian cancer. Ten women whose cancer came back after initial chemotherapy will receive both drugs for 12 weeks. The main goal is to see how many patients have their disease shrink or stay stable.

Active substance

oregovomab (a monoclonal antibody) and niraparib (a drug, brand name Zejula)

What this could lead to

What could go wrong
