U.S. Food and Drug Administration approved Retevmo (selpercatinib) capsules to treat three types of tumors – non-small cell lung cancer, medullary thyroid cancer and other types of thyroid cancers – in patients whose tumors have an alteration (mutation or fusion) in a specific gene (RET or “rearranged during transfection”). Retevmo is the first therapy approved specifically for cancer patients with the RET gene alterations.
