Preferred Label : TRK Inhibitor VC004;
NCIt definition : An orally bioavailable, second-generation tropomyosin-related-kinase (TRK) inhibitor,
with potential antineoplastic activity. Upon oral administration, TRK inhibitor VC004
specifically targets and binds to TRK, TRK mutations and fusion proteins containing
sequences from neurotrophic tyrosine receptor kinase (NTRK) types 1 (NTRK1; TrkA),
2 (NTRK2; TrkB), and 3 (NTRK3; TrkC). This inhibits neurotrophin-TRK interaction and
TRK activation, thereby preventing the activation of downstream signaling pathways,
including the PI3K, RAS/MAPK/ERK and PLC-gamma pathways that are activated by these
kinases. This results in both the induction of cellular apoptosis and the inhibition
of cell growth in tumors that overexpress TRK and/or express NTRK fusion proteins.
TRK, a family of receptor tyrosine kinases (RTKs) activated by neurotrophins, is encoded
by NTRK family genes. The expression of either mutated forms of, or fusion proteins
involving NTRK family members results in uncontrolled TRK signaling, which plays an
important role in tumor cell growth, survival, invasion and treatment resistance.;
