Selpercatinib, sold under the brand name Phoselp40 Retevmo, is a medication for the treatment of non-small cell lung cancer, medullary thyroid cancer, and other types of thyroid cancers in people whose tumors have an alteration (mutation or fusion) in a specific gene (RET or "rearranged during transfection"). It is taken by mouth.
The most common side effects include changes in laboratory tests (including increased liver enzymes, increased blood sugar, decreased white cell and platelet counts, decreased protein level, decreased calcium, increased total cholesterol, increased creatinine, and decreased sodium) dry mouth, diarrhea, high blood pressure, fatigue, edema, rash, and constipation.
Selpercatinib is a kinase inhibitor, meaning it blocks a type of enzyme (kinase) and helps prevent the cancer cells from growing.Before beginning treatment, the identification of a RET gene alteration must be determined using laboratory testing.
Selpercatinib is the first therapy approved specifically for people with cancer and the RET gene alterations.
Selpercatinib is a kinase inhibitor indicated for the treatment of
adults with non-small cell lung cancer (NSCLC) which has spread to other parts of the body (metastatic).
adults and children twelve years of age and older with advanced or metastatic medullary thyroid cancer (MTC).
adults and children twelve years of age and older with advanced or metastatic thyroid cancer who have received radioactive iodine that did not work or is no longer working.
Why is this medication prescribed?
Selpercatinib is used to treat a certain type of non-small cell lung cancer (NSCLC) in adults that has spread to other parts of the body in adults. It is also used to treat a certain type of thyroid cancer in adults and children 12 years of age and older that has spread to other parts of the body. Selpercatinib is also used to treat another type of thyroid cancer that has spread to other parts of the body in adults and children 12 years of age and older who have been treated unsuccessfully with radioactive iodine.
