his is an open-label, single-center, single-arm, prospective Phase II trial evaluating the efficacy and safety of Mirvetuximab Soravtansine (MIRV) combined with Suvemcitug (SV) in patients with folate receptor alpha (FRα)-positive, platinum-resistant recurrent epithelial ovarian, fallopian tube, or primary peritoneal cancer. A total of 20 eligible patients will receive MIRV (6 mg/kg AIBW IV Q3W) and Suvemcitug (1.5 mg/kg IV Q2W) until disease progression or intolerable toxicity. The primary endpoint is investigator-assessed Progression-Free Survival (PFS) per RECIST v1.1.
