Study of the MUC1 Peptide-Poly-ICLC Adjuvant Vaccine in Individuals With Advanced Colorectal Adenoma
The purpose of this study is to evaluate the immune response to MUC1 - poly-ICLC vaccine, an investigational or study vaccine. The MUC1 - poly-ICLC vaccine is being tested in persons with a history of advanced adenomatous polyps, the precursor to colorectal cancer. The MUC1 - poly-ICLC vaccine is being developed to prevent polyps from advancing into colon cancer and to prevent polyps from recurring.
MUC1 is mucus that is normally present on the lining of the human colon. However, MUC1 is expressed in a larger amount and in a modified form on adenomatous polyps and colorectal cancer. These changes in MUC1 are thought to be part of the process of progression from adenomas toward cancer. The goal of a vaccine is to help the immune system in the body identify the changes in MUC1 that accompany the progression to cancer and eliminate the abnormal cells that make abnormal MUC1.

|Official Title:||Study of the MUC1 Peptide - Poly-ICLC Adjuvant Vaccine in Individuals With Advanced Colorectal Adenoma|
- Number of Participants With Anti Muc-1 Antibody [ Time Frame: 52 weeks ] [ Designated as safety issue: Yes ]Evaluation of the immune response to MUC1 peptide vaccine administered with Poly-ICLC, measured by Anti MUC1 antibody, in patients with a history of advanced colorectal adenoma.
- Number of Participants With Autoimmune Response to Muc-1 Vaccine [ Time Frame: 52 weeks ] [ Designated as safety issue: No ]Evaluate for autoimmune response by measuring the Anti-muc-1 IgG antibodies to the muc-1 vaccine.
- Number of Participants With Adverse Events Associated With the Study Agent [ Time Frame: 54 weeks ] [ Designated as safety issue: Yes ]Laboratory monitoring including Toxicity laboratory test or monitored through out the study up to week 54.
|Study Start Date:||October 2008|
|Study Completion Date:||October 2012|
|Primary Completion Date:||October 2011 (Final data collection date for primary outcome measure)|
|Experimental: MUC1 Poly-ICLC||
Biological: MUC1 - Poly ICLC
The vaccine will be administered on an outpatient basis in the Digestive Disorders Clinic. The total volume of each dose of vaccine MUC1+ POLY-ICLC will be approximately 250 microliters subcutaneously (SQ) in the upper thigh. The site of injection will remain the same thigh, to enhance the potential immune response.
