SHR-1210, BP102, Phase II
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.
