General information

Class/mechanism: EGFR antagonist; monoclonal antibody that binds to the EGFR/HER1/c-ErbB-1 receptor tyrosine kinase, competitively inhibiting binding of epidermal growth factor (EGF) and other ligands, such as transforming growth factor-alpha. This results in inhibition of cell growth, induction of apoptosis, decreased matrix metalloproteinase, and decreased vascular endothelial growth factor production.[1][2][3]
Route: IV
Extravasation: neutral

For conciseness and simplicity, HemOnc.org currently will focus on treatment regimens and not list information such as: renal/hepatic dose adjustments, metabolism (including CYP450), excretion, monitoring parameters (although this will be considered for checklists), or manufacturer. Instead, for the most current information, please refer to your preferred pharmacopeias such as Micromedex, Lexicomp, UpToDate (courtesy of Lexicomp), or the prescribing information.[1]
