Lilly Accelerated Approval for Retevmo
FDA has granted Eli Lilly accelerated approval three months ahead of schedule for Retevmo (selpercatinib) for certain patients with non-small cell lung cancer or thyroid cancer. Approval was based on data from the LIBRETTO-001 clinical trial. Data showed that in NSCLC patients the overall response rate (ORR) was 64%, with 81% of responding patients having responses lasting six months or longer, an FDA release says. In advanced or metastatic ret proto-oncogene (RET)-mutant medullary thyroid cancer the ORR was 69%; 76% of responding patients had responses lasting six months or longer. And in RET fusion-positive thyroid cancer patients the ORR was 79%; 87% of responding patients had responses lasting six months or longer. The RET gene provides instructions for producing a protein that is involved in signaling within cells.
The agency says that the most common adverse reactions, including laboratory abnormalities, were increased aspartate aminotransferase, increased alanine aminotransferase, increased glucose, decreased leukocytes, decreased albumin, decreased calcium, dry mouth, diarrhea, increased creatinine, increased alkaline phosphatase, hypertension, fatigue, edema, decreased platelets, increased total cholesterol, rash, decreased sodium, and constipation.
