Clinical trials and retrospective study results of c-KIT inhibitors in melanomas [60,61,62,63,64,65,66,67,68,69,70]. (A) Median progression-free survival and overall survival in melanoma patient cohorts treated with different c-KIT inhibitors. These trials and retrospective studies must not be compared as patient inclusion criteria, trial designs, and KIT mutation subtypes are different. (B) Overall response rates in melanoma cohorts treated with c-KIT inhibitors. * Kalinsky et al. study analyzed PFS and OS in melanoma patients with KIT mutations involving exons 11 and 13 only [69]. PFS: progression-free survival; OS: overall survival.
