Mechanism of action

XELOX is a combination chemotherapy regimen (capecitabine and oxaliplatin) that damages cancer cell DNA and inhibits proliferation. Sintilimab is a humanized monoclonal antibody that blocks PD-1 on T cells, removing the immune checkpoint that allows tumors to evade immune surveillance. Together, the chemotherapy primes the immune system while sintilimab enhances T-cell activation against tumor antigens.
