| RET C630Y | medullary thyroid carcinoma | sensitive | Selpercatinib | FDA approved - On Companion Diagnostic | Actionable | In a Phase I/II trial (LIBRETTO-001) that supported FDA approval, Retevmo (selpercatinib) treatment resulted in an objective response rate (ORR) of 69% (38/55, 5 complete and 33 partial responses) in previously treated adult and pediatric patients of 12 years and older with medullary thyroid cancer harboring RET mutations as detected by an approved test, including RET C630Y; ORR was 73% (64/88) in treatment naive patients (PMID: 32846061; NCT03157128). | 32846061 detail... detail... |
