Mavelertinib (Synonyms: PF-06747775)

Mavelertinib is a selective, orally available and irreversible EGFR tyrosine kinase inhibitor (EGFR TKI), with IC50s of 5, 4, 12 and 3 nM for Del, L858R, and double mutants T790M/L858R and T790M/Del, respectively. Mavelertinib can be used for the research of non-small-cell lung cancer (NSCLC)[1][2][3][4].

Mavelertinib exhibits selectivity over wild-type EGFR (IC50=307 nM)[1].Mavelertinib (10 μM) exhibits less than 50% e?ect or inhibition against all nonkinase targets[1].Mavelertinib inhibits the hERG26 current with an IC50 > 100 μM[1].

Mavelertinib exhibits low to moderate oral bioavailability (mouse 60%, rat 11%, dog 66%) following oral administration (mouse 1, rat 30, dog 3 mg/kg)[1].Mavelertinib exhibits short plasma half-lives (mouse 0.56, rat 0.28, dog 1.3 h) due to moderate to high plasma clearance (mouse 53, rat 49, dog 12 mL/min/kg) and low steady-state volume of distribution (mouse 1.48, rat 0.66, dog 0.94 L/kg) following intravenous administration (1 mg/kg to mouse, rat and dog)[1]. Animal Model: Female Nu/Nu mice[1]
