Dabogratinib

**Semantic type:** Pharmacologic Substance

**Definition:** An orally bioavailable, selective inhibitor of human fibroblast growth factor receptor 3 (FGFR3), with potential antineoplastic activity. Upon oral administration, dabogratinib specifically targets and binds to certain FGFR3 activating gene alterations, and specifically the gatekeeper mutants V555L/M. This blocks FGFR3-mediated signaling and leads to an inhibition of tumor cell proliferation in FGFR3-overexpressing cells. FGFR3, a receptor tyrosine kinase, is involved in angiogenesis and in the proliferation, differentiation, and survival of tumor cells. FGFR3 expression is associated with poor prognosis. It is overexpressed by certain tumor cell types.
