Trastuzumab Rezetecan and Carboplatin ± Bevacizumab Versus Investigator's Choice Chemotherapy in Patients With Platinum-sensitive Recurrent Ovarian Cancer

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).
