| Initial U.S. Approval: 2016
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 releases the PD-L1/PD-1 mediated inhibition of the immune response, including activation of the anti-tumor immune response without inducing antibody-dependent cellular cytotoxicity. In syngeneic mouse tumor models, blocking PD-L1 activity resulted in decreased tumor growth.
| INDICATIONS AND USAGE:

-Have disease progression during or following platinum-containing chemotherapy (1)
