Pertuzumab (Perjeta®) and trastuzumab are targeted therapy drugs used to treat breast cancer. They are usually given with chemotherapy.
Can tamoxifen and Herceptin be given together?
Conclusions: The combination of tamoxifen and Herceptin is formally demonstrated to result in synergistic growth inhibition and enhancement of G(0)-G(1) cell cycle accumulation. In vitro, the individual drugs or combination produces a cytostatic effect.
What is the difference between Herceptin and Herceptin Hylecta?
Herceptin contains one active ingredient, trastuzumab, and is given as an intravenous (IV) infusion slowly into a vein. Herceptin Hylecta contains two active ingredients, trastuzumab and hyaluronidase-oysk, and is given as a subcutaneous injection, which is an injection that goes under the skin.
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.
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.
