Gefitinib News and Research

RSS

Gefitinib is approved by the Food and Drug Administration (FDA) to treat locally advanced or metastatic non-small cell lung cancer (NSCLC) that has not gotten better after treatment with other chemotherapy. It is available only as part of a special program called the Iressa Access Program. Gefitinib is also being studied in the treatment of other types of cancer.

Gefitinib is an anilinoquinazoline with antineoplastic activity. Gefitinib inhibits the catalytic activity of numerous tyrosine kinases including the epidermal growth factor receptor (EGFR), which may result in inhibition of tyrosine kinase-dependent tumor growth. Specifically, this agent competes with the binding of ATP to the tyrosine kinase domain of EGFR, thereby inhibiting receptor autophosphorylation and resulting in inhibition of signal transduction. Gefitinib may also induce cell cycle arrest and inhibit angiogenesis.

Pfizer announces FDA approval of VIZIMPRO for first-line treatment of EGFR-mutated metastatic NSCLC

Pfizer Inc. today announced that the U.S. Food and Drug Administration has approved VIZIMPRO [vih-ZIM-pro] (dacomitinib), a kinase inhibitor for the first-line treatment of patients with metastatic non-small cell lung cancer with epidermal growth factor receptor exon 19 deletion or exon 21 L858R substitution mutations as detected by an FDA-approved test.
