Trastuzumab is a recombinant DNA-derived IgG1 kappa monoclonal antibody that selectively binds to the extracellular domain of the human epidermal growth factor receptor 2 protein, HER2. Trastuzumab has been shown to inhibit the proliferation of human tumor cells that overexpress HER2. Trastuzumab is also a mediator of antibody-dependent cellular cytotoxicity (ADCC). Trastuzumab-mediated ADCC, a method of cancer cell destruction, is preferentially exerted on those cancer cells which overexpress HER2.
Trastuzumab for the treatment of the following is considered medically necessary if the medical appropriateness criteria are met. (See Medical Appropriateness below.)
Central Nervous system cancers
Esophagogastric junction adenocarcinoma
Trastuzumab for the treatment of other conditions/diseases is considered investigational.
Trastuzumab is considered medically appropriate if ALL of the following:

Individual is 18 years of age or older
Cancer is human epidermal growth factor receptor 2 (HER2)-positive
Diagnosis of ANY ONE of the following:

Trastuzumab is considered medically appropriate if for renewal if All of the following:
Individual continues to meet ALL of the initial criteria
Tumor shows response with stabilization of disease or decrease in size of tumor or tumor spread
Absence of unacceptable toxicity from the drug, e.g., cardiotoxicity, such as left ventricular dysfunction or cardiomyopathy; pulmonary toxicity (e.g., pneumonitis); neutropenia; neurotoxicity; infusion-related and hypersensitivity reactions
Left ventricular ejection fraction (LVEF) has not had an absolute decrease of more than 15% from baseline and is within normal limits
Use for neoadjuvant and adjuvant breast cancer treatment is limited to a total of 52 weeks of therapy
