| Description | A recombinant IgG1 kappa, humanized monoclonal antibody that selectively binds with high affinity in a cell-based assay (Kd = 5 nM) to the extracellular domain of the human epidermal growth factor receptor protein. Produced in CHO cell culture. |
| Indication/Disease | For treatment of early stage HER2-positive breast cancer, or metastatic breast cancer that substantially overexpress HER2. |
| Pharmacodynamics | Used in the treatment of HER2-positive breast cancer. HER2 protein overexpression is observed in 25%-30% of primary breast cancers.Trastuzumab has been shown, in both in vitro assays and in animals, to inhibit the proliferation of human tumorcells that overexpress HER2. It is a mediator of antibody dependent cellular cytotoxicity, in that the binding of the antibody to HER2 overexpressing cells leads to preferential cell death. |
| Mechanism of Action | Trastuzumab binds to the HER2 (or c-erbB2) proto-oncogene, an EGF receptor-like protein found on 20-30% of breast cancer cells. The binding leads to antibody mediated (complement mediated) killing of the HER2 positive cells. |
| Toxicity | Administration of trastuzumab can result in ventricular dysfunction and congestive heart failure. Risk of cardiotocity is especially elevated in patients recieving concurrent anthracycline or cyclophosphamide therapy. |
| Metabolism | Most likely removed by opsonization via the reticuloendothelial system. |
| Absorption | Peak and trough plasma concentrations at steady state (between weeks 16 and 32) were approximately 123 and 79 mcg/mL, respectively. At the highest weekly dose studied (500 mg), mean peak serum concentration was 377 mcg/mL |
| 46 mL/kg |
| Clearance | The predicted steady-state clearance of trastuzumab is 0.173 - 0.337 L/day, dependent primarily on the dosing regimen. The clearance rate for subcutaneously administered trastuzumab, formulated with hyaluronidase for improved subcutaneous absorption, is 0.11 L/day. |

| Formulation | Trastuzumab-anns is a humanized IgG1 kappa monoclonal antibody that selectively binds with high affinity to the extracellular domain of the human epidermal growth factor receptor 2 protein, HER2. Trastuzumab-anns is produced by recombinant DNA technology in a mammalian cell (Chinese Hamster Ovary) culture containing the antibiotic geneticin. Geneticin is not detectable in the final product. |
| Physical Appearance | sterile, white to pale yellow, preservative-free lyophilized powder with a cake-like appearance |
| Route of Administration | intravenous administration. |
| Recommended Dosage | Initial dose of 4 mg/kg as an intravenous infusion over 90 minutes then at 2 mg/kg as an intravenous infusion over 30 minutes weekly during chemotherapy for the first 12 weeks (paclitaxel or docetaxel) or 18 weeks (docetaxel and carboplatin). One week following the last weekly dose of KANJINTI, administer KANJINTI at 6 mg/kg as an intravenous infusion over 30–90 minutes every three weeks. |
