Entrectinib (NMS-E628) is a potent, orally available, and CNS-active pan-Trk, ROS1, and ALK inhibitor. Entrectinib inhibits TrkA, TrkB, TrkC, ROS1 and ALK with IC₅₀ values of 1, 3, 5, 12 and 7 nM, respectively. Antitumor activity.

IC50: 1 nM (TrkA), 1 nM (TrkB), 1 nM (TrkC), 1 nM (ROS1),1 nM (ALK)^[1]

Entrectinib (NMS-E628) is found to be exquisitely active in inhibiting the proliferation of a limited number of cell lines: the TRKA-driven colorectal carcinoma cell line KM12 (IC₅₀ of 17 nM), the ALK-dependent ALCL cell lines SU-DHL-1, Karpas-299, SUP-M2 and SR-786 (IC₅₀ of 20, 31, 41, and 81 nM, respectively), the ALK-dependent NSCLC cell line NCI-H2228 (IC₅₀ of 68 nM) and the FLT3-dependent AML cell line MV-4-11 (IC₅₀ of 81 nM). Entrectinib potently blocks proliferation of Ba/F3-TEL-TRKB (IC₅₀ of 2.9 nM), Ba/F3-TEL-TRKC (IC₅₀ of 3.3 nM), and Ba/F3-TEL-ROS1 (IC₅₀ of 5.3 nM) cells, with a high degree of selectivity versus parental Ba/F3 cells or those transformed by nontargeted kinases such as ABL and RET, which are inhibited with IC₅₀s in the range of 2 to 3 μM^[1]. Entrectinib significantly inhibits the growth of TrkB-expressing NB cells in vitro, and it significantly enhances the growth inhibition of Irino-TMZ when used in combination^[2].

Oral administration of entrectinib to tumor-bearing mice induces regression in relevant human xenograft tumors, including the TRKA-dependent colorectal carcinoma KM12, ROS1-driven tumors, and several ALK-dependent models of different tissue origins, including a model of brain-localized lung cancer metastasis^[1]. Single agent therapy results in significant tumor growth inhibition in animals treated with entrectinib compared to control animals^[2].

NLF, NLF-TrkB, SY5Y or SY5Y-TrkB cells are plated in 96 well plates, and they are exposed to drug at different concentrations (1, 5, 10, 20, 30, 50 and 100 nM of entrectinib, 1.5 μM Irino and 50 μM TMZ, respectively) for one hr followed by addition of 100 ng/mL of BDNF. Plates are harvested at 24, 48, and 72 hr following addition of drug. The plates are processed and cell viability is analyzed using a standard SRB assay protocol^[2].

Mice: Entrectinib is reconstituted in 0.5% methylcellulose containing 1% Tween 80 at a final dosing volume of 10 mL/kg (e.g., 0.2 mL for a 20 gm mouse). Treatment with entrectinib, Irino and TMZ started about 15–17 days after tumor inoculation when the average tumor size is 0.2 cm³. Mice are sacrificed when tumor volume reached 3 cm³. Tumors are harvested and flash frozen on dry ice for analysis of protein expression^[2].
