NCIt definition : An orally available inhibitor of the epidermal growth factor receptor (EGFR), with
potential antineoplastic activity. Upon oral administration, zorifertinib binds to
and inhibits the activity of EGFR as well as certain mutant forms of EGFR. This prevents
EGFR-mediated signaling, and may lead to both induction of cell death and inhibition
of tumor growth in EGFR-overexpressing cells. EGFR, a receptor tyrosine kinase mutated
in many tumor cell types, plays a key role in tumor cell proliferation and tumor vascularization.;
