Therapy Name | Gefitinib |
Synonyms | |
Therapy Description |
Iressa (gefitinib) is a first-generation EGFR inhibitor that binds EGFR and inhibits downstream signaling, potentially resulting in decreased growth of tumors with EGFR activation (PMID: 26980062, PMID: 25302162, PMID: 15284455). Iressa (gefitinib) is FDA approved for use in patients with non-small cell lung cancer harboring an EGFR exon 19 deletion or EGFR L858R (FDA.gov). |
