Drug data last refreshed 1h ago · AI intelligence enriched 1mo ago
IRESSA (gefitinib) is an oral small-molecule tyrosine kinase inhibitor that blocks EGFR signaling in cancer cells. It is indicated for treatment of non-small cell lung cancer (NSCLC) in patients with EGFR-sensitizing mutations. The drug works by inhibiting the epidermal growth factor receptor protein kinase, thereby halting tumor cell proliferation.
Product is approaching loss of exclusivity with modest Part D spending, signaling potential team contraction and transition to post-LOE defense strategies.
