The Safety and Efficacy of HAIC+Tislelizumab+Regorafenib in Patients With Colorectal Liver Metastases

An Open Label, Single-center Study on the Safety of Hepatic Arterial Infusion Chemotherapy Combined With Tislelizumab and Regorafenib in Patients With Advanced Treated Colorectal Liver Metastases

Tislelizumab is an anti-PD-1 monoclonal antibody with high binding affinity for PD-1 and with minimized Fcγ receptor binding on macrophages. Regorafenib has been approved in mCRC by CFDA. Hepatic arterial infusion chemotherapy has a high local control rate for liver metastases. NCCN guidelines and several expert consensus recommend that regional hepatic arterial infusion chemotherapy can be considered as a "rescue treatment" for patients with colorectal cancer liver metastases who fail to receive first-line or second-line systemic chemotherapy, which can significantly prolong the overall survival of patients.

7. Subject life expectancy ≥12 weeks

8. Laboratory tests of bone marrow, hepatic and renal function and coagulation function within 7 days before the first dose of medication meet the study requirements

   - No blood transfusion, blood products, or correction with granulocyte colony-stimulating factor or other hematopoietic stimulating factor within 7 days before laboratory testing.

9. Female patients of childbearing age must have a negative blood pregnancy test within 7 days before the first dose of medication and male or female patients of childbearing age volunteered to take effective contraceptive measures during the whole treatment and within 3 months after treatment
