Lirafugratinib

**Semantic type:** Pharmacologic Substance

**Definition:** An orally bioavailable inhibitor of the fibroblast growth factor receptor 2 (FGFR2), with potential antineoplastic activity. Upon oral administration, lirafugratinib binds to and inhibits FGFR2, which results in the inhibition of FGFR2-mediated signal transduction pathways. This inhibits the proliferation of FGFR2-overexpressing tumor cells. FGFR2, a receptor tyrosine kinase upregulated in many tumor cell types, plays a key role in cellular proliferation, migration and survival.
