General information
Class/mechanism: HER2/neu receptor antagonist, humanized IgG1 kappa monoclonal antibody. Trastuzumab binds to the extracellular domain of HER2/erbB2 (human epidermal growth factor receptor 2), which is overexpressed in certain malignancies. Trastuzumab helps to mediate antibody-dependent cellular cytotoxicity (ADCC) preferentially against cells that overexpress HER2.[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]

- 11/16/2006: Label revised: trastuzumab as part of a treatment regimen containing doxorubicin, cyclophosphamide, and paclitaxel is indicated for the adjuvant treatment of patients with HER2-overexpressing, node-positive breast cancer.
- 1/18/2008: Labeling simplified: indicated for the treatment of HER2 overexpressing breast cancer.
- 10/20/2010: Label expanded to include the treatment of HER2-overexpressing metastatic gastric or gastroesophageal junction adenocarcinoma.
