Tác dụng
Description:
Mechanism of Action: Pertuzumab is a recombinant humanised monoclonal antibody that targets extracellular dimerization domain of human epidermal growth factor receptor 2 protein (HER2). It prevents heterodimerisation of HER2 with other HER family receptors, thereby preventing activation of HER signalling pathways. This results in cell growth arrest and apoptosis. Additionally, it mediates antibody-dependent cell-mediated cytotoxicity.
Trastuzumab is a monoclonal antibody that binds to the extracellular domain of human epidermal growth factor receptor 2 (HER2) protein. It inhibits proliferation of tumour cells that overexpress HER2 protein thereby mediating antibody-dependent cellular cytotoxicity.
Pharmacokinetics:
Absorption: Pertuzumab: Absolute bioavailability: 0.712. Time to peak plasma concentration: 3.82 days.
Trastuzumab: Absolute bioavailability: 0.771. Time to peak plasma concentration: 3.84 days.
Distribution: Pertuzumab: Volume of distribution: Central compartment: 2.77 L.
Trastuzumab: Volume of distribution: Central compartment: 2.91 L.
Excretion: Pertuzumab: Elimination half-life: Approx 24.3 days.
