| Indication |
Pertuzumab is indicated for use in combination with trastuzumab and docetaxel for the treatment of patients with HER2-positive metastatic breast cancer who have not received prior anti-HER2 therapy or chemotherapy for metastatic disease. |
| Mechanism of action |
Pertuzumab is a humanized monoclonal antibody designed to bind to the HER2 receptor and inhibit the ability of HER2 to interact with other HER family members (HER1, HER2, HER3, and HER4) on the surface of cancer cells. The HER signaling pathway plays a role in the formation and growth of numerous cancers, and previous clinical trials of pertuzumab in a single agent setting had suggested clinical activity - including stable disease - in heavily pretreated patients with advanced ovarian and breast cancers. |
| Absorption |
When an initial dose of 840 mg followed by a maintenance dose of 420 mg every three weeks thereafter is administered, steady-state concentrations were achieved on the first maintenance dose. |
