Brief summary: This is an open label, single-arm, multi-center, phase II study of SHR-1210 in metastatic colorectal cancer patients with the recurrent lesion(s) post-surgery or the untreated mCRC.

SHR-1210 is a humanized monoclonal antibody against Programmed death 1(PD-1).BP102 is a humanized recombinant monoclonal IgG1 antibody.

The primary objective of this study is to investigate the safety and efficacy of the subjects who given the combination therapy.

5. At least 6 months have elapsed if considering the interval from the time of firstly documented metastasis to the post-operational adjuvant chemotherapy termination
6. Can provide either a newly obtained or archival tumor tissue sample.
7. Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
8. Life expectancy ≥ 3 months
9. Subjects must have normal organ and marrow function as defined below:
