AbbVie announced that the U.S. Food and Drug Administration (FDA) has granted full approval for ELAHERE® (mirvetuximab soravtansine-gynx) for the treatment of folate receptor alpha (FRa)-positive, platinum-resistant epithelial ovarian, fallopian tube or primary peritoneal adult cancer patients treated with up to three prior therapies. Patients with these cancers often present with late-stage disease, undergo surgery and are then treated with platinum-based chemotherapy. They may become resistant to this treatment and require another therapy, such as ELAHERE.

ELAHERE was first granted FDA accelerated approval in November 2022 and the conversion to full approval is based on data from the confirmatory Phase 3 MIRASOL trial. This trial compared ELAHERE to investigator's choice (IC) of chemotherapy in patients with platinum-resistant ovarian cancer (PROC) whose tumors express high levels of FRa and who have been treated with up to three prior therapies. The primary endpoint of MIRASOL was progression-free survival (PFS) by investigator assessment and key secondary endpoints included objective response rate (ORR) and overall survival (OS).
