Mirvetuximab soravtansine in folate receptor alpha-positive, platinum-resistant ovarian cancers: a profile of its use

Mirvetuximab soravtansine (Elahere^TM), an antibody-drug conjugate carrying a maytansinoid payload targeting folate receptor alpha (FRα), is a valuable new treatment option for patients with FRα-positive, platinum-resistant ovarian cancer. Mirvetuximab soravtansine significantly improved objective response rates compared with historical rates in patients with FRα-positive, platinum-resistant ovarian cancer in the phase 2 SORAYA trial. In the confirmatory phase 3 MIRASOL trial, mirvetuximab soravtansine significantly improved median progression-free survival, objective response rates, and median overall survival compared with investigator’s choice of nonplatinum chemotherapy in patients with this indication. Mirvetuximab soravtansine has manageable tolerability, with eye disorders being the most common treatment-related adverse event.
