Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study evaluates the effect and safty of PD-1 monoclonal antibody-activated autologous peripheral blood lymphocyte (PD1-T) combined with XELOX and bevacizumab in the first-line treatment of recurrent and metastatic colorectal cancer. Half of participants receive PD1-T combined with XELOX and bevacizumab, while the other half will receive XELOX and bevacizumab.
