Colon Cancer Clinical Trial
Vaccine Therapy in Treating Patients With Newly Diagnosed Advanced Colon Polyps
This randomized phase II clinical trial studies how well MUC1 peptide-poly-ICLC adjuvant vaccine works in treating patients with newly diagnosed advanced colon polyps (adenomatous polyps). Adenomatous polyps are growths in the colon that may develop into colorectal cancer over time. Vaccines made from peptides may help the body build an effective immune response to kill polyp cells. MUC1 peptide-poly-ICLC adjuvant vaccine may also prevent the recurrence of adenomatous polyps and may prevent the development of colorectal cancer.
I. To compare the immunogenicity at week 12 of a MUC1 peptide vaccine with adjuvant (MUC1 peptide-poly-ICLC adjuvant vaccine) (administered at 0, 2, and 10 weeks) in participants with a history of an advanced adenoma, randomized to receive MUC1 peptide vaccine versus placebo.
I. To evaluate the ability of the vaccine to elicit a long-term memory response.
II. To compare the adenoma recurrence rate from surveillance exams occurring at least 1 year and up to 3 years after week 0 vaccine administration - MUC1 versus placebo.
III. To compare the adenoma recurrence rates between MUC1 and placebo by excluding the following types of adenomas: participants with adenomas =< 5 mm; participants with adenomatous tissue which may represent residual adenoma at the site of the previous advanced adenoma; participants with adenomatous tissue detected in the same segment of the bowel as the previous advanced adenoma.
IV. To assess adverse events to the MUC1 peptide vaccine in comparison to placebo during Parts I and II.
V. To assess patient reported injection site reaction events from the Vaccine Report Card.
I. To compare the anti-MUC1 antibody titer at the time of surveillance colonoscopy for the purpose of evaluating the anti-MUC1 antibody response in relation to adenoma recurrence.
II. To evaluate MUC1 expression on baseline advanced adenomas and on recurrent adenomas detected at surveillance colonoscopy.
III. To evaluate levels of circulating myeloid derived suppressor cells (MDSC) in the vaccinated and the placebo group and correlate with anti-MUC1 antibody levels and adenoma recurrence.
IV. To establish a biospecimen repository archive including live cells, plasma, and germline deoxyribonucleic acid (DNA) for future immunologic (e.g. MUC1-specific T cells) and other assays (systems biology approach to detect differences between responders and non-responders), testing not currently accommodated within the budget of this trial.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM I: Participants receive MUC1 peptide-poly-ICLC adjuvant vaccine subcutaneously (SC) in weeks 0, 2 and 10 and a booster injection in week 53.
ARM II: Participants receive saline SC in weeks 0, 2, and 10 and a booster injection in week 53.
After completion of treatment, patients are followed up every 6 months for up to 3 years.
History of at least one of the following conditions in the previous 12 months:
Colorectal adenoma(s) >= 1 cm in maximal diameter
Colorectal adenoma(s) with villous or tubulovillous histology
Colorectal adenoma(s) with high grade (severe) dysplasia
Presumptive evidence that all adenomatous lesions, including qualifying advanced adenoma, have been completely removed

Willingness to provide blood samples for toxicity monitoring and research purposes
Not pregnant or nursing; note: a negative (serum or urine) pregnancy test must be documented =< 7 days prior to registration/randomization for women of childbearing potential
Willingness to employ adequate contraception through week 53 of the study; note: women of childbearing potential and men must agree to use adequate contraception (hormonal, barrier method of birth control, abstinence) prior to study entry and for the period of active vaccination (through week 53); should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her physician immediately

Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT]), alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 1.5 x institutional upper limit of normal
Alkaline phosphatase =< 1.5 x institutional upper limit of normal
Total bilirubin =< 1.5 x institutional upper limit of normal
Blood urea nitrogen (BUN) =< 1.5 x institutional upper limit of normal
Creatinine =< 1.5 x institutional upper limit of normal
Antinuclear antibody (ANA) test result excludes overt autoimmune disease; note: test result may be reported in any of the following formats: =< 1:160, negative, or < 1.0
History of any colorectal cancer
History of other malignancy =< 5 years prior to the registration/randomization evaluation, with the exception of basal cell or squamous cell skin cancer
Presence of an active acute or chronic infection or uncontrolled illness including, but not limited to unstable congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
Acquired immunosuppressive diseases such as active human immunodeficiency virus (HIV) infection or congenital diseases of immunity
History of heritable cancer syndrome (familial adenomatous polyposis [FAP], hereditary nonpolyposis colorectal cancer [HNPCC])
History of auto-immune disease such as, but not restricted to, inflammatory bowel disease, systemic lupus erythematosus, rheumatoid arthritis, ankylosing spondylitis, scleroderma, multiple sclerosis, Hashimoto's thyroiditis, or Grave's disease

History of allergic reactions attributed to compounds of similar chemical or biologic composition to the study agent
Diagnosis of nonalcoholic steatohepatitis (NASH) and a NAFLD (nonalcoholic fatty liver disease) activity score (NAS) >= 5; NOTES and EXCEPTIONS: NAS is based on findings from a liver biopsy; participants with NAS of =< 2 are eligible for enrollment; participants with NAS of 3-4 must be discussed with the principal investigator and Division of Cancer Prevention (DCP) before enrollment to consider other risk factors (i.e., obesity, alcohol intake); participants with a prior diagnosis of NASH and no available NAS must be discussed with the principal investigator and DCP before enrollment to considered risk factors (i.e., obesity, alcohol intake)
