Action
Description:
Mechanism of Action: Atezolizumab is a humanised immunoglobulin G1 (IgG1) monoclonal antibody which binds to programmed death ligand 1 (PD-L1) and selectively prevents the interaction between PD-1 and B7.1 (also known as CD80) receptors found on T-cells and antigen presenting cells, releasing PD-L1/PD-1 mediated inhibition of immune response thereby enhancing the immune response to tumour cells.
Pharmacokinetics:
Distribution: Volume of distribution at steady state: 6.9 L.
Excretion: Elimination half-life: 27 days.
Storage
Store between 2-8°C. Do not freeze. Protect from light.
This is a cytotoxic drug. Any unused portions should be disposed of in accordance with local requirements.
