NCIt definition : An inhibitor of human fibroblast growth factor receptor 4 (FGFR4), with potential
antineoplastic activity. Upon administration, roblitinib binds to and inhibits the
activity of FGFR4, which leads to an inhibition of tumor cell proliferation in FGFR4-overexpressing
cells. FGFR4 is a receptor tyrosine kinase upregulated in certain tumor cells and
involved in tumor cell proliferation, differentiation, angiogenesis, and survival.;
