Study of Activated Cytokine-induced Killer Armed With Bispecific Antibody for Advanced Colorectal Cancer

Phase II Randomized Comparison Clinical Trial of Target Activated CIK for Advanced Colorectal Cancer

This is a phase II Randomized comparison clinical trial of activated CIK armed with anti-CD3-MUC1 bispecific antibody for advanced colorectal cancer. And the aim of this research is to study the clinical efficacy and safety of activated CIK armed with anti-CD3-MUC1 bispecific antibody for colorectal cancer.

Primary colorectal carcinoma is one of the most common malignancies in China, Immunotherapy is considered to be one of the most promising means of human against cancer. This is a phase II clinical trial of single- center, The investigators plan to recruit for 90 patients with advanced colorectal cancer,and all patients are divided into three groups.one group will receive cryotherapy, one group will receive conventional therapy，and the rest one will receive mixed liquor of activated CIK and anti-CD3-MUC1 bispecific antibody together with cryotherapy.

The result of this study was statistic and analysed with the record of Response Evaluation Criteria In Solid Tumors(RECIST1.1) evaluation standard.

Inclusion Criteria:

• 18-75 years old
• The patient is diagnosed as advanced colorectal cancer,MUC1 is positive
• There is at least one tumor should be measured,and length≥10mm of focus not at lymph node or length≥10mm of focus at lymph node
• The patient can't tolerate system(systemic chemotherapy/molecular targeted therapy) or local therapies
• If the patient received adjuvant chemotherapy after local treatment,the time should be more than 4 weeks after the end of chemotherapy, and disease progression or metastasis patients can also assigned into the group
• The time of surgical treatment≥ 3 months ;At the end of the intervention,radiotherapy and the end of the ablation time is more than 4 weeks
• The expected survival time ≥12 weeks
• The patient did not took any antitumor drugs within 4 weeks(any antitumor drugs, Chinese patent medicine including Delisheng injection,Kanglaite injection, Aidi injection
• No serious disease are conflicts with the solution(such as autoimmune disease,immunodeficiency,organ transplantation)
• Sign the informed consent

Exclusion Criteria:
