Entrectinib: An orally available, selective tyrosine kinase inhibitor for the treatment of NTRK, ROS1, and ALK fusion-positive solid tumors

Abstract

Entrectinib is a potent small-molecule tyrosine kinase inhibitor that targets oncogenic rearrangements in NTRK, ROS1, and ALK. The consolidated results of 2 Phase I trials demonstrated activity in tyrosine kinase inhibitor-naïve patients along with substantial intracranial activity. In ROS1-rearranged lung cancers, entrectinib results in durable disease control and prolonged progression-free survival. The drug is well tolerated and has a safety profile that includes adverse events mediated by on-target tropomyosin-related kinase A/B/C inhibition.
