Platinum Sensitive Ovarian Cancer (PSOC)

This study is a randomized, open-label, controlled phase II clinical trial. It is planned to enroll 176 subjects with platinum-sensitive recurrent epithelial ovarian cancer, fallopian tube cancer, or primary peritoneal cancer previously treated with Poly (ADP-ribose) polymerase inhibitors (PARPi). Subjects will be randomly assigned in a 1:1 ratio to receive either the experimental treatment group (trastuzumab Rezetecan + carboplatin ± bevacizumab) or the control treatment group (investigator's choice chemotherapy ± bevacizumab).

This study will test the safety, including side effects, and determine the characteristics of a drug called Rina-S in participants with solid tumors. Participants will have solid tumor cancer that has spread through the body (metastatic) or cannot be removed with surgery (unresectable).
