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.[1] Specifically it is for cases that are folate receptor alpha (FRα) positive that have failed other treatments.[1] It is given by gradual injection into a vein.[1]

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.[1] Other side effects may include pneumonitis.[1] Use in pregnancy may harm the baby.[1] It is a monoclonal antibody directed at FRα attached to a microtubule inhibitor.[1]

Mirvetuximab soravtansine was approved for medical use in the United States in 2022.[1] It is available as an orphan medication in Europe.[3] In the United States it costs about 25,000 USD every three weeks as of 2022.[4]

Medical uses

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.[1][2] Recipients are selected for therapy based on an FDA-approved test.[2] Corticosteroids, antihistamines, and acetaminophen are generally used before it is given to reduce side effects.[1]

Dosage

It is given at a dose of 6 mg/kg ideal body weight every three weeks.[1]

Side effects

The product labeling includes a boxed warning for eye problems.[1][2]

History

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.[2] Participants were permitted to receive up to three prior lines of systemic therapy.[2] All participants were required to have received bevacizumab.[2] The trial enrolled participants whose tumors were positive for FRα expression as determined by the above assay.[2] Participants were excluded if they had corneal disorders, ocular conditions requiring ongoing treatment, Grade >1 peripheral neuropathy, or noninfectious interstitial lung disease.[2]
