Atezolizumab is an Fc-engineered, humanized, monoclonal antibody that binds to Programmed Death Ligand 1 (PD-L1) and blocks its interactions with the receptors B7.1 (also known as CD80) and Programmed Death 1 (PD-1). The binding of PD-L1 to PD-1 or B7.1 on activated T cells causes an inhibitory signal to suppress their production in the lymph nodes, thereby preventing immune responses to events such as pregnancy or autoimmune disease. This pathway is also utilized by cancer cells to evade the immune system through evasion of anti-tumor T-cell response. Furthermore, over-expression of PD-L1 and PD-1 has been linked to increased tumour aggressiveness and poorer prognosis. Currently the only antibody against PD-L1 and available as the product Tecentriq (FDA), atezolizumab is indicated for the treatment of locally advanced or metastatic urothelial carcinoma.


For the treatment of patients with locally advanced or metastatic urothelial carcinoma who: 1) have disease progression during or following platinum-containing chemotherapy, and 2) have disease progression within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy.

Mechanism of Action

Atezolizumab is a monoclonal antibody that binds to PD-L1 and blocks its interactions with both PD-1 and B7.1 receptors. This prevents PD-L1/PD-1 mediated inhibition of the immune response, including activation of the anti-tumor immune response without inducing antibody-dependent cellular cytotoxicity.


The population PK analysis suggests steady state is obtained after 6 to 9 weeks (2 to 3 cycles) of repeated dosing. The systemic accumulation in area under the curve (AUC), maximum concentration (Cmax) and trough concentration (Cmin) was 1.91, 1.46 and 2.75-fold, respectively.
