Description
Curator's Comment: description was created based on several sources, including http://www.accessdata.fda.gov/drugsatfda_docs/nda/2013/201292Orig1s000PharmR.pdf

Afatinib is a anilino-quinazoline derivative and irreversible antagonist of the receptor tyrosine kinase epidermal growth factor receptor family, with antineoplastic activity. Afatinib selectively and covalently binds to and inhibits the epidermal growth factor receptors 1 (ErbB1; EGFR), 2 (ErbB2; HER2), and 4 (ErbB4; HER4), and certain EGFR mutants, including those caused by EGFR exon 19 deletion mutations or exon 21 (L858R) mutations. This may result in the inhibition of tumor growth and angiogenesis in tumor cells overexpressing these kinases. Additionally, afatinib inhibits the EGFR T790M gatekeeper mutation which is resistant to treatment with first-generation EGFR inhibitors. EGFR, HER2 and HER4 are RTKs that belong to the EGFR superfamily; they play major roles in both tumor cell proliferation and tumor vascularization and are overexpressed in many cancer cell types. Afatinib is a substrate and an inhibitor of P-gp and of the transporter BCRP. Co-administration of P-gp inhibitors can increase afatinib exposure while co-administration of chronic P­gp inducers can decrease afatinib exposure.

CNS Activity

Curator's Comment: Afatinib appears to penetrate into the CNS with concentrations high enough to have clinical effect on CNS metastases

Comment: Afatinib is a substrate and inhibitor (Ki=3.4 μM) for P-gp transporter and exposure to afatinib was changed when it was administered with a P-gp inhibitor, ritonavir (AUC increased by 48%) or with a P-gp inducer, rifampicin (AUC decreased by 34%).

Sample Use Guides

The recommended dose is 40 mg orally once daily.
Route of Administration: Oral
In cellular in vitro assays, afatinib was able to inhibit phosphorylation and/or proliferation of multiple cell lines representing models of overexpression of wild type EGFR, constitutively active HER2, and EGFR exon 19 deletion mutations, including an exon 19/T790M double mutant. Concentrations of afatinib required for activity in these models ranged from approximately 10 to 100 nM; effects on exon 19/T790M double mutants typically occurred at the high end of this range.

a case of successful treatment of a patient aged >80 years with lung adenocarcinoma positive for the uncommon EGFR L861Q mutation with low‐dose afatinib. An 83‐year‐old woman presented with cough and dyspnea. A chest computed tomography (CT) scan revealed tumors in the left upper lobe, left pleural effusion, and multiple lung metastases in both lungs. The patient was diagnosed with lung adenocarcinoma with an EGFR L861Q mutation based on cytological findings. The patient received 30 mg/day of afatinib and experienced no severe adverse events.
