Mirvetuximab soravtansine, sold under the brand name Elahere, is a medication used to treat certain types of ovarian cancer, fallopian tube cancer, and primary peritoneal cancer. Specifically it is for cases that are folate receptor alpha (FRα) positive that have failed other treatments. It is given by gradual injection into a vein.
Common side effects include vision problems, tiredness, liver problems, nausea, abdominal pain, low white blood cells, peripheral neuropathy, diarrhea, constipation, low magnesium, and low hemoglobin. Other side effects may include pneumonitis. Use in pregnancy may harm the baby. It is a monoclonal antibody directed at FRα attached to a microtubule inhibitor.
Mirvetuximab soravtansine was approved for medical use in the United States in 2022. It is available as an orphan medication in Europe. In the United States it costs about 25,000 USD every three weeks as of 2022.
Mirvetuximab soravtansine is indicated for the treatment of adults with folate receptor alpha (FRα) positive, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer, who have received one to three prior systemic treatment regimens. Recipients are selected for therapy based on an FDA-approved test. Corticosteroids, antihistamines, and acetaminophen are generally used before it is given to reduce side effects.
Efficacy was evaluated in Study 0417 (NCT04296890), a single-arm trial of 106 participants with FRα positive, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer. Participants were permitted to receive up to three prior lines of systemic therapy. All participants were required to have received bevacizumab. The trial enrolled participants whose tumors were positive for FRα expression as determined by the above assay. Participants were excluded if they had corneal disorders, ocular conditions requiring ongoing treatment, Grade >1 peripheral neuropathy, or noninfectious interstitial lung disease.
