Efficacy of Adjuvant Cytokine-induced Killer Cells in Colon Cancer (CIKCC)

August 27, 2013 updated by: Yanjuan Zhu

Efficacy of Adjuvant Immunotherapy With Cytokine-induced Killer Cells in Patients With Stage II/III Colon Cancer

It has been reported that the immune status of patients with cancer were suppressed, especially those after surgery and adjuvant chemotherapy. Thus, immunotherapy may decrease the recurrence rate after surgery. CIK cells transfusion has been reported as an effect therapy in advanced cancers. In another retrospective study, investigators found that adjuvant CIK therapy would prolong the disease-free survival (DFS) for colorectal cancer patients.

The purpose of this study is to determine wether adjuvant immunotherapy with CIK cells in patients with colon cancer after operation will prolong DFS, and overall survival (OS).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
