Information
Larotrectinib (LOXO-101) sulfate Larotrectinib sulfate (LOXO-101, ARRY-470) is an oral potent and selective ATP-competitive inhibitor of tropomyosin receptor kinases (TRK) . Larotrectinib inhibition of TRKs induces cellular apoptosis and G1 cell-cycle arrest.
Targets
TRK
In vitro
ARRY-470(LOXO-101) is a selective kinase inhibitor with nanomolar activity against TRKA, TRKB and TRKC but no other notable kinase inhibition below 1,000 nM. ARRY-470 does not inhibit proliferation of Ba/F3 cells expressing other oncogene targets (epidermal growth factor receptor (EGFR), ALK or ROS1) or of lung and colorectal cell lines that do not harbor an NTRK1 fusion. It induces cell-cycle arrest in G1 and apoptosis of KM12 cells.
In vivo
Early/sustained but not late/acute administration of ARRY-470(LOXO-101) markedly attenuates bone cancer pain and significantly blocks the ectopic sprouting of sensory nerve fibers and the formation of neuroma-like structures in the tumor bearing bone, but does not have a significant effect on tumor growth or bone remodeling. It has very limited ability crossing of the blood brain barrier.
