- IV infusionAtezolizumabTecentriq
- Mechanism of Action
- A monoclonal antibody directed against PD-L1, an inhibitory molecule expressed on certain tumour cells.
PD-L1 and PD-L2 are ligands that bind to PD-1 receptors on activated lymphocytes and inhibit T cell receptor signalling, downregulating immune responses and promoting tolerance.
Binding of anti-PD-L1 monoclonal antibodies leaves the ligand unable to bind to PD-1, and therefore stimulates an ongoing immune response.
PD-L2 is not inhibited, allowing PD-1 / PD-L2 mediated inhibitory signals to continue.
