研究人员正在寻找更好的方法来治疗晚期大肠癌患者。 结肠直肠癌（结肠或直肠癌）是全球最常见的癌症之一。 治疗包括手术、化疗、放射治疗和免疫治疗；然而，这些治疗并不适用于所有人，可能导致严重不良事件或最终可能停止工作。

排除标准
- Prior systemic treatment for advanced CRC. Participants may have received prior adjuvant chemotherapy as long as disease progression occurred at least 12 months after the last dose of adjuvant treatment
- Prior treatment with adjuvant immunotherapy (e.g., anti-PD-1, anti-PD-L1, anti-PD-L2 agent, or anti-CTLA-4 agent, or any other antibody or drug specifically targeting T cell co-stimulation or immune checkpoint pathways, including prior therapy with anti-tumor vaccines or other immuno-stimulatory antitumor agents, etc.)
