DrugBank Description: | Pertuzumab is a recombinant humanized monoclonal antibody that targets the extracellular dimerization domain (subdomain II) of the human epidermal growth factor receptor 2 protein (HER2). It consists of two heavy chains and two lights chains that have 448 and 214 residues respectively. It was first approved by the FDA in 2012 for use with and another HER2-targeted monoclonal antibody, , in the treatment of metastatic HER2-positive breast cancer. Its indicated conditions have since expanded to include use as both a neoadjuvant therapy and an adjuvant therapy in the treatment of HER2-positive breast cancers at high risk of recurrence. |

Molecular Weight: | |
DrugBank Indication: | Pertuzumab is indicated for intravenous administration in combination with and for the treatment of patients with HER2-positive metastatic breast cancer who have not received prior anti-HER2 therapy or chemotherapy for metastatic disease. It is also indicated in combination with trastuzumab and other chemotherapies for the neoadjuvant treatment of HER2-positive locally advanced, inflammatory, or early-stage breast cancer as part of a complete treatment regimen and as adjuvant treatment in patients with HER2-positive early-stage breast cancer at high risk of recurrence. Pertuzumab is also indicated for subcutaneous injection - in combination with trastuzumab and - in the treatment of HER2-positive breast cancers in adults. |
DrugBank Pharmacology: | Pertuzumab exerts its antineoplastic effects by binding to and inhibiting the activity of HER2, an oncogene that has been implicated in the formation of numerous cancers. As with other therapeutic monoclonal antibodies, pertuzumab has a relatively long duration of action necessitating dosing every 3 weeks. Drugs that block HER2 activity, including pertuzumab, have been implicated in the development of cardiotoxicity (specifically left ventricular dysfunction) - a baseline assessment of left ventricular ejection fraction (LVEF) should be conducted prior to beginning therapy with pertuzumab and at regular intervals throughout therapy to ensure LVEF remains within normal limits. Consider indefinite suspension of therapy if LVEF declines and does not improve. |
DrugBank MoA: | Human epidermal growth factor receptor-2 (HER2) is a tyrosine kinase receptor that plays an integral role in cell proliferation, differentiation, and survival. HER2 becomes active following dimerization with another HER2 receptor, another member of the HER protein family (e.g. HER3), or with a ligand - this dimer then phosphorylates and activates numerous intracellular signaling proteins, initiating signal transduction via pathways that include the Ras/mitogen-activated protein kinase pathway, the phosphatidylinositol 3' kinase (PI3K)/Akt pathway, and then Janus kinases/signal transducer and activator transcription pathway. HER2 is also a known oncogene - it is overexpressed or gene-amplified (i.e. HER2-positive) in approximately 20% of breast cancers and these cancers carry a generally poorer prognosis than HER2-negative breast cancers. Pertuzumab targets the extracellular dimerization domain (subdomain II) of HER2, thereby inhibiting ligand-initiated intracellular signaling via the MAP kinase and PI3K pathways. Inhibition of these pathways results in inhibition of cell growth and the initiation of apoptosis, respectively. Pertuzumab also appears to mediate antibody-dependent cell-mediated cytotoxicity. |
