atezolizumab

Atezolizumab is an antibody inhibitor, a humanized monoclonal antibody, IgG1, which targets PD-L1 and blocks the interaction of PD-L1 with PD-1. Atezolizumab has antitumor activity and promotes T-cells to attack tumor cells.

RO7567132 (FAP-LTBR) is a novel bispecific antibody that binds and agonizes LTBR bivalently while binds and antagonizes FAP monovalently, thereby limiting the activation of LTBR to the tumor microenvironment, inducing the formation of local tertiary lymphoid structures (TLS), and reducing systemic toxicity. Its mouse alternative can inhibit breast cancer growth, and the effect is better when combined with atezolizumab. In the mouse colorectal cancer model, it can also enhance immune cell infiltration and TLS-like structure formation.

Tiragolumab(MTIG-7192A) is a monoclonal antibody that targets T-cell immunoglobulin and the ITIM structural domain (TIGIT).Tiragolumab is often used in combination with the PD-L1 inhibitor, Atezolizumab, for the treatment of solid malignant tumors such as non-small cell lung cancer.
