Pertuzumab (also known as 2C4, Omnitarg, trade name Perjeta , manufacturer Genentech / Roche ) is a monoclonal antibody that is used together with trastuzumab and docetaxel in the treatment of HER2- positive breast cancer .
history
Perjeta was developed by Genentech . Approval for the treatment of HER2-positive metastatic breast cancer was granted by the American health authority FDA in June 2012. In 2013, approval in Europe was granted by the European Medicines Agency EMA.
Effective range
The HER family of transmembrane receptor tyrosine kinases and HER2 in particular have been identified as important targets in the fight against breast cancer. The signal transmission through HER plays an essential role in tumor growth as well as in cell differentiation . The recombinant humanized monoclonal antibody pertuzumab binds specifically to the extracellular dimerization domain (subdomain II) of the growth factor receptor protein HER2. The heterodimerization with other receptors (e.g. HER3 and HER4) is also inhibited. This is to prevent the tumor from growing . In addition, pertuzumab is also a mediator for antibody-dependent cell-mediated cytotoxicity ( ADCC, antibody dependent cellular cytotoxicity ).
administration
At the start of therapy, 840 mg pertuzumab is administered together with 8 mg / kg trastuzumab and 75 mg / m 2 docetaxel . After three weeks, 420 mg pertuzumab is administered together with 6 mg / kg trastuzumab and 75 or 100 mg / m 2 docetaxel.
Side effects
In the clinical studies, neutropenia , insomnia, loss of appetite, diarrhea and vomiting were found as side effects.
Clinical studies
Administration of pertuzumab together with trastuzumab and docetaxel demonstrated significantly increased progression-free survival in the multinational phase III clinical study CLEOPATRA. In other currently ongoing clinical studies MARIANNE (advanced breast cancer), NEOSPHERE (breast cancer in the initial stage) and TRYPHAENA (HER2-positive breast cancer in stage II / III), pertuzumab is being evaluated in patients.
