Exclusion Criteria:
* Unable to tolerate previous regorafenib treatment or previously received immune checkpoint inhibitors;
* Pregnant or breastfeeding;
* Expected survival less than 3 months;
* Underwent major surgery or experienced significant trauma within 4 weeks before the first blood draw during the screening period, or expected to need major surgery during the study;
* Currently have active ulcers or gastrointestinal bleeding;
* History of interstitial lung disease or non-infectious pneumonia; history of active tuberculosis;
* Uncontrolled pleural effusion, pericardial effusion, or ascites requiring repeated drainage;
* Clinically diagnosed autoimmune disease; HIV or HCV positive; HBV-DNA exceeding laboratory normal range; acute CMV infection;
