Trastuzumab and pertuzumab are types of targeted cancer drugs. You might have them on their own or with other chemotherapy drugs. It is a treatment for breast cancer.
What is the difference between trastuzumab and pertuzumab?
Pertuzumab is a fully humanized monoclonal antibody which binds to domain II of HER2, essential for dimerization [27, 59], while trastuzumab binds to domain IV. Pertuzumab efficiently inhibits ligand-induced HER2/HER3 dimerization, whereas trastuzumab has only a minor effect in the presence of a ligand.
Why is Perjeta given before Herceptin?
Updated results from the APHINITY trial confirmed that adding Perjeta (chemical name: pertuzumab) to Herceptin (chemical name: trastuzumab) and chemotherapy after surgery for early-stage HER2-positive breast cancer reduces the risk of recurrence (the cancer coming back) and slightly improves survival.
What is trastuzumab pertuzumab based therapy?
Pertuzumab (Perjeta®) and trastuzumab are targeted therapy drugs used to treat breast cancer. They are usually given with chemotherapy.
Why do patients receive pertuzumab in combination with trastuzumab?
The combination of IV pertuzumab, IV trastuzumab, and chemotherapy has been shown to lead to improved outcomes in patients with HER2-positive breast cancer versus IV trastuzumab plus chemotherapy alone.
Is pertuzumab an immunosuppressant?

Does pertuzumab affect immune system?
Perjeta and Herceptin are examples of immune targeted therapy. In addition to blocking HER2 receptors, Perjeta can also help fight breast cancer by alerting the immune system to destroy cancer cells onto which it is attached.
Is pertuzumab approved in the US?
Background: A subcutaneous formulation of pertuzumab and trastuzumab with recombinant human hyaluronidase in one ready-to-use, fixed-dose combination vial (pertuzumab, trastuzumab, and hyaluronidase-zzxf) was approved by the US Food and Drug Administration (FDA) on June 29, 2020.
What is the role of pertuzumab in the treatment of metastatic cancer?
The addition of pertuzumab further improved upon results achieved with trastuzumab and chemotherapy, specifically extending overall survival in patients with metastatic disease, lessening the risk of recurrence when used in the adjuvant setting, and improving pathologic complete response rate when utilized in the neoadjuvant setting.
What is trastuzumab used to treat?
Trastuzumab was first approved by the US Food and Drug Association (FDA) in 1998 to treat patients with metastatic breast cancer whose tumors overexpress the HER2 protein and who have received at least one chemotherapy regimen for metastatic disease.
