Study of Carboplatin and Mirvetuximab Soravtansine in First-Line Treatment of Patients Receiving Neoadjuvant Chemotherapy With Advanced-Stage Ovarian, Fallopian Tube or Primary Peritoneal Cancer

Mirvetuximab soravtansine (also known as IMGN853 and MIRV) is an antibody-drug conjugate (ADC) that consists of a high affinity humanized monoclonal antibody against folate receptor α (FRα, the protein product of the folate receptor 1 \[FOLR1\] gene) that is conjugated to a cytotoxic maytansinoid by the hindered disulfide succinimidyl 4-(pyridin-2-yl)disulfanyl)-2-sulfo-butyrate linker (sulfo-SPDB) linker. FRα is a glycosyl-phosphatidylinositol (GPI)-linked protein, which shows limited normal tissue expression and high expression on the surface of solid tumors, particularly epithelial ovarian cancer, fallopian tube cancer, and primary peritoneal cancer (referenced herein collectively as EOC), endometrial cancer, non-small cell lung cancer (NSCLC), and renal cell cancer.
