General information

Class/mechanism, from the NCI Drug Dictionary: An orally bioavailable inhibitor of the tyrosine kinases tropomyosin receptor kinases (Trk) A, B and C, C-ros oncogene 1 (ROS1) and anaplastic lymphoma kinase (ALK), with potential antineoplastic activity. Upon administration, entrectinib binds to and inhibits TrkA, TrkB, TrkC, ROS1 and ALK. Inhibition of these kinases may result in a disruption of TrkA-, TrkB-, TrkC-, ROS1-, and ALK-mediated signaling. This leads to an induction of apoptosis and an inhibition of tumor cell proliferation in tumor cells that express these kinases.
Route: PO
Extravasation: n/a

For conciseness and simplicity, HemOnc.org currently will focus on treatment regimens and not list information such as: renal/hepatic dose adjustments, metabolism (including CYP450), excretion, monitoring parameters (although this will be considered for checklists), or manufacturer. Instead, for the most current information, please refer to your preferred pharmacopeias such as Micromedex, Lexicomp, UpToDate (courtesy of Lexicomp), or the prescribing information.
