Immunotherapy combined with chemotherapy has become the standard first-line treatment regimen for gastric cancer. However, a subset of patients still fail to benefit or derive only limited benefit from this approach. This study aims to evaluate the addition of immunomodulatory EZH2 inhibitors or anti-angiogenic agents to the baseline regimen of immunotherapy combined with chemotherapy, in order to further improve patient treatment benefits.
