Glesatinib (MGCD265) is a potent, orally bioavailable, spectrum-selective small molecule inhibitor primarily targeting MET and AXL receptor tyrosine kinases. It exhibits strong activity against MET kinase with an IC₅₀ of 1.7 nM and against AXL with an IC₅₀ of 0.4 nM in biochemical assays. Glesatinib is particularly effective in tumors harboring MET exon 14 skipping mutations or MET amplification, showing selective inhibition of MET-driven cell proliferation in preclinical models. In early-phase clinical trials, Glesatinib demonstrated partial responses in non-small cell lung cancer (NSCLC) patients with MET alterations, confirming its mechanism-based activity. Additionally, it shows minimal off-target kinase inhibition, contributing to its relatively favorable safety profile in early human studies.
