Background

Nazartinib is an irreversible inhibitor of mutant EGF receptors (EGFRs).¹ It is selective for EGFR mutant cell lines, including H3255 and HCC827 lung adenocarcinoma cells (IC₅₀s = 6.11 and 1.52 nM, respectively) and resistant H1975 non-small cell lung cancer cells (NSCLC; IC₅₀ = 4.18 nM), over cells expressing wild-type EGFRs (IC₅₀ = 160.6 nM for HaCaT keratinocytes). Nazartinib decreases phosphorylation of EGFR in H3255, HCC827, and H1975 cells (EC₅₀s = 5, 1, and 3 nM, respectively) and inhibits cell proliferation (EC₅₀s = 9, 11, and 25 nM, respectively) but does not affect cell proliferation in cell lines containing wild-type EGFR.² It reduces tumor growth in an HCC827 lung adenocarcinoma mouse xenograft model when administered at doses ranging from 3 to 100 mg/kg per day for 21 days.
