M. Vae writes (citation below): “Ponatinib, another multikinase inhibitor, has shown activity on KITV560G and, less effectively, on KITD816V in the human mast cell leukemia cell line human mast cell line-1 (HMC-1) (67, 68). Ponatinib also synergizes with midostaurin to obtain growth inhibition against neoplastic mast cells harboring the KITD816V mutant. However, clinical trials are needed to assess the in vivo efficacy of ponatinib, alone or in combination.” Arock et al expresses the same sentiment.
