abstract = {The KIT D816V mutation is found in more than $80\%$ of
patients with systemic mastocytosis (SM) and is key to
neoplastic mast cell (MC) expansion and accumulation in
affected organs. KIT D816V therefore represents a prime
therapeutic target for SM. Here we generated a panel of
patient-specific KIT D816V induced pluripotent stem cells
(iPSCs) from patients with aggressive SM (ASM) and mast cell
leukemia (MCL) to develop a patient-specific SM disease
model for mechanistic and drug discovery studies. KIT D816V
iPSCs differentiated into neoplastic hematopoietic
progenitor cells and MCs with patient-specific phenotypic
features, thereby reflecting the heterogeneity of the
disease. CRISPR/Cas9n-engineered KIT D816V human embryonic
stem cells (ESCs), when differentiated into hematopoietic
cells, recapitulated the phenotype observed for KIT D816V
iPSC hematopoiesis. KIT D816V causes constitutive activation
of the KIT tyrosine kinase receptor and we exploited our
iPSCs and ESCs to investigate new tyrosine kinase inhibitors
targeting KIT D816V. Our study identified nintedanib as a
novel KIT D816V inhibitor. Nintedanib selectively reduced
the viability of iPSC-derived KIT D816V hematopoietic
progenitor cells and MCs in the nanomolar range. Nintedanib
was also active on primary samples of KIT D816V SM patients.
Molecular docking studies show that nintedanib binds to the
ATP binding pocket of inactive KIT D816V. Our results
suggest nintedanib as a new drug candidate for KIT D816V
targeted therapy of advanced SM.},
