Products
Atezolizumab was approved as an infusion product in the United States in 2016 and in the EU and many countries in 2017 (Tecentriq).
Structure and properties
Atezolizumab is a humanized IgG1κ monoclonal antibody with a molecular mass of 145 kDa.
Effects
Atezolizumab (ATC L01XC32) has immunostimulatory and antitumor properties. The effects are due to binding to PD-L1, programmed cell death ligand 1. PD-L1 is a ligand of the PD-1 receptor that mediates immunosuppression. Some tumors express the ligand on the cell surface, protecting themselves from the body’s defenses. By binding to PD-L1, atezolizumab stimulates T-cell activation and proliferation, enabling the destruction of cancer cells. The half-life of the antibody is 27 days.
