Why is this medication prescribed?

Mirvetuximab soravtansine-gynx Injection is prescribed for the treatment of specific types of cancer, including epithelial ovarian, fallopian tube, or primary peritoneal cancer. It is typically recommended when these cancers express a specific protein called folate receptor alpha (FRα), which is found on the surface of some cancer cells. Mirvetuximab soravtansine is a targeted therapy that works by binding to the FRα protein and delivering a chemotherapy agent (soravtansine) directly to the cancer cells, which can help inhibit their growth and cause cell death.

The drug is used to treat cancer that has either relapsed (returned after initial treatment) or become resistant to other forms of therapy. It may be prescribed when other treatment options have been exhausted or have not been effective.
