Imatinib is approved for treatment of cancers carrying primary mutations in the KIT receptor. Imatinib binds and inhibits the inactive state of the receptor, including the conformation promoted by exon 11 mutations that relieve the auto-inhibition of the WT protein. Resistance to imatinib arises due to the polyclonal expansion of subpopulations bearing secondary KIT mutations in the ATP binding pocket or the activation loop of the protein (Serrano et al, 2019; reviewed in Roskoski, 2018; Klug et al, 2018; Corless et al, 2011).
