Indications
- Her2-positive metastatic breast cancer, in combination with trastuzumab & docetaxel (FDA-approved 6-8-12)*
- early stage breast cancer prior to surgery[3]
- increases likelihood of being cancer=free 12 weeks after surgery by 18%[3]
* addition of pertuzumab to docetaxel & trastuzumab as a 1st-line treatment for HER2-positive metastatic breast cancer is associated with 16 months longer survival (57 months vs 41 months)[4]
* NICE rejects adjuvant pertuzumab in HER2(+) breast cancer; may not offer meaningful benefit[5]
Dosage
- loading dose of 840 mg, followed by 420 mg every 3 weeks until disease progression or the development of unmanageable toxicity
Adverse effects
- minimal additional adverse effects with the addition of pertuzumab to trastuzumab & docetaxel
Mechanism of action
- pertuzumab is a humanized monoclonal antibody that binds HER2 (at a different site than trastuzumab) & stimulates antibody-dependent, cell-mediated cytotoxicity
- synergy with trastuzumab
