Neptinib

Neptinib (NEP010), a derivative of Afatinib, exhibits enhanced antitumor properties and improved pharmacokinetics when administered orally. It demonstrates a notable suppression of tumor expansion in mouse models of non-small cell lung cancer harboring various EGFR mutations. Furthermore, Neptinib effectively inhibits the EGFR kinase family, exhibiting IC 50 values of 0.24 nM for EGFR wt, 7.25 nM for EGFR L858R/T790M, 0.46 nM for EGFR L858R, and 1.79 nM for EGFR T790M.
