A Study of Selpercatinib (LOXO-292) in Participants With Advanced Solid Tumors, RET Fusion-Positive Solid Tumors, and Medullary Thyroid Cancer (LIBRETTO-001)

Summary

This is an open-label, first-in-human study designed to evaluate the safety, tolerability, pharmacokinetics (PK) and preliminary anti-tumor activity of selpercatinib (also known as LOXO-292) administered orally to participants with advanced solid tumors, including rearranged during transfection (RET)-fusion-positive solid tumors, medullary thyroid cancer (MTC) and other tumors with RET activation.
