Trastuzumab is a recombinant humanized monoclonal immunoglobulin G1 kappa antibody that binds with high affinity and specificity to the extracellular domain of the HER2 receptor. A growth factor receptor gene, human epidermal growth factor receptor (HER2), is amplified in 25 to 30 % of breast cancers and in these cases the encoded protein is present in abnormally high levels in the malignant cells. Trastuzumab is used to treat adjuvant and metastatic breast cancer as well as metastatic gastric cancer.
