Description: |
EGF816 (Nazartinib) is a potent, irreversible, mutant-selective EGFR inhibitor with Ki and Kinact of 31 nM and 0.222 min-1, respectively; shows potent inhibition of pEGFR levels in H3255, HCC827, and H1975 with EC50 of 5, 1, and 3 nM, which harbor the L858R, Ex19del, and L858R/T790M mutations, respectively, inhibitscell proliferation with EC50 of 9, 11, and 25 nM, but not the WT EGFR-containing patient-derived cell lines; potently inhibits the most common EGFR mutations L858R, Ex19del, and T790M in vitro; causes tumor regressions in vivo in several patient-derived xenograft models, also demonstrates antitumor activity in exon 20 insertion mutant model.Lung CancerPhase 3 Clinical |
