New combo therapy aims to shrink ovarian tumors before surgery
NCT ID NCT07432594
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding an experimental immunotherapy (Aitua Combination Antibody) to standard chemotherapy can help shrink advanced ovarian cancer more effectively before surgery. About 82 women with stage IIIC-IV high-grade serous ovarian cancer who cannot have optimal surgery upfront will receive either chemo alone or chemo plus the immunotherapy for 3 cycles, then undergo surgery. The main goal is to see if more tumors can be completely removed during surgery with the combination.
