TIGIT is a negative regulator of innate and adaptive immune responses. AGEN1327 is a fully human monoclonal antibody that boosts the immune response to cancer cells by blocking the interaction between TIGIT and its binding partner CD155. Moreover, AGEN1327 is one of our next-generation antibodies which has been “Fc enhanced” to maximize antitumor activity (see AGEN1181). Therefore, we expect that AGEN1327 will bring clinical benefit above and beyond that of conventional anti-TIGIT antibodies. TIGIT signaling has also been identified as a key resistance mechanism to anti-PD-1 therapy, suggesting that AGEN1327 can address therapeutic resistance to anti-PD-1 therapy.
