  • Failure of treatment after previous standard chemotherapy for metastatic colorectal cancer (including disease progression and unacceptable adverse reactions):
  • (1)Chemotherapy regimens must include fluorouracil (5-fluorouracil/capecitabine /S-1), oxaliplatin and irinotecan (2)Patients receiving oxaliplatin in adjuvant therapy should develop disease progression during adjuvant therapy or within 6 months after completion of adjuvant therapy; (3)patients may have previously received bevacizumab and/or cetuximab and/or rigfinil and/or furoquitinib.
  • 8\. The primary tumor of the colon or rectum has been surgically removed, or the liver metastases are considered to be irretrievable after the evaluation of a multidisciplinary colorectal cancer team consisting of at least two gastrointestinal surgeons, one hepatobiliary surgeon, one oncologist, one interventional surgeon, and one radiologist.
  • 9\. The following laboratory test values obtained during the root screening period (reaching the standard and stable before participating in the study) have appropriate organ functions: Neutrophil count \>= 1.5 x 109/L, platelet count \>= 75 x 10\^9/L, serum total bilirubin \<= upper normal limits UNL), aspartate aminotransferase \<= 2 x UNL, alanine aminotransferase \<= 2 x UNL, serum creatinine \<= 1.5 x UNL.
  • 10\. Negative urine or serum pregnancy tests in women of reproductive age within 7 days prior to treatment.

Exclusion

  • The presence or co-existence of other active malignancies (other than those that have been curable for more than 5 years and have received curative treatment or carcinoma in situ that can be cured with adequate treatment).
  • Subjects have central nervous system metastasis or previous brain metastases.
  • Had received hepatic arterial infusion chemotherapy, hepatic arterial embolization chemotherapy or hepatic radiotherapy within 3 months.
  • Received liver surgery (except biopsy for liver metastasis) and liver interventional ablation within the previous 3 months.
  • CT angiography showed severe arterial embolism or hepatic arterial variation.
  • Partial prothrombin time (APTT) or prothrombin time (PT) exceeded 1.5 x ULN (based on the normal value in the clinical trial research center), or patients with evidence or history of bleeding tendency within 2 months prior to enrollment, regardless of severity.
  • Active infection less than 7 days after completion of systemic antibiotic therapy.
  • Major surgery or severe trauma, such as laparotomy, thoracotomy, laparoscopic viscerectomy, etc. within 4 weeks prior to enrollment (surgical incisions should be completely healed before randomization).
  • Active coronary artery disease, severe/unstable angina or newly diagnosed angina or myocardial infarction within 12 months prior to enrollment.
  • Thrombosis or embolism events, such as cerebrovascular accident (including transient ischemic attack), pulmonary embolism, and deep vein thrombosis, occurred within 12 months prior to enrollment.
  • The New York Heart Association (NYHA) has grade II congestive Heart failure or higher (see Appendix 2).

  • 13\. Presence of any active, known or suspected autoimmune disease. Subjects who are in a stable state and do not require systemic immunosuppressive therapy, such as type I diabetes, hypothyroidism requiring only hormone replacement therapy, and skin conditions that do not require systemic therapy (e.g., vitiligo, psoriasis, and hair loss) are allowed to be enrolled.
  • 14\. Presence of interstitial lung disease, non-infectious pneumonia or uncontrolled systemic disease (e.g., diabetes, hypertension, pulmonary fibrosis and acute pneumonia).
  • 15\. Common Terminology Criteria for Adverse Events (CTCAE) (version 5.0) grade 2 or above toxicity (except anaemia, hair loss, skin pigmentation) arising from any prior treatment that has not subsided.
  • 16\. Programmed death-1 within 3 months Pd-1) or its ligand (PD-L1) antibody, anti-cytotoxic T-lymphocyte associated protein 4 (CTLA-4) antibody, or other drugs/antibodies that act on T cell co-stimulation or checkpoint pathways.
  • 17\. Positive pregnancy test before first use in women who are pregnant or breast-feeding or who are at risk of pregnancy.
  • 18\. The investigator considers that the subject has any clinical or laboratory abnormalities or compliance issues that make it inappropriate to participate in this clinical study.
  • 19\. There are serious psychological or mental abnormalities. 20. Participated in clinical trials of other drugs within 4 weeks.
