NCIt definition : An orally available inhibitor of the epidermal growth factor receptor (EGFR) mutant
form T790M, with potential antineoplastic activity. Upon administration, aumolertinib
binds to and inhibits EGFR T790M, a secondarily acquired resistance mutation, inhibits
the tyrosine kinase activity of EGFR T790M, prevents EGFR T790M-mediated signaling
and leads to cell death in EGFR T790M-expressing tumor cells. EGFR, a receptor tyrosine
kinase that is mutated in many tumor cell types, plays a key role in tumor cell proliferation
and tumor vascularization.;
