Phase I Repeat-Dose Study of Resveratrol in Colorectal Cancer Patients: Tolerability, Target Tissue Levels and Pharmacodynamics


I. Determine the relationship between oral dose of resveratrol and the colon mucosal levels
of resveratrol and its metabolites in patients with resectable colorectal cancer.

II. Determine the relationship between colon mucosal levels of resveratrol and its
metabolites and plasma concentrations of resveratrol and its metabolites in these patients.

III. Determine cyclooxygenase-2 (COX-2) expression in colorectal cancer tissue before and
after treatment in these patients.

IV. Determine M_1G concentration in colonic cancer tissue and in circulating white blood
cells (WBC) before and after treatment.

V. Correlate M_1G concentration in colorectal cancer tissue with M_1G concentration in
circulating WBC.

VI. Assess the Ki67 labeling index in normal and malignant tissues in at least 10 fields per

VII. Correlate COX-2 expression in colorectal cancer tissue with COX-2 expression in
circulating WBCs.

VIII. Assess the toxicity profile of this drug.

OUTLINE: This is a two-stage nonrandomized, open-label study. Patients are assigned to 1 of
2 dose levels in stage 2.

STAGE I: Patients undergo an colorectal endoscopy. Patients whose biopsies confirm
colorectal adenocarcinoma histology and require surgical resection continue on study stage

STAGE II: Patients receive oral resveratrol on days 1-8. Patients undergo colorectomy on day
9. A tumor biopsy is performed during endoscopy and colorectomy for research purposes.

Two biomarkers of the potential activity of resveratrol are measured in nonmalignant and
malignant colorectal tissue biopsy samples: levels of M_1G adducts by immunoslot blot
analysis and levels of cyclooxygenase-2 protein/Ki67 by immunohistochemistry. Blood samples
are collected at baseline and during colorectomy for analysis of resveratrol and its
metabolites and other pharmacokinetic studies.

Inclusion Criteria:

for men or women, respectively)

- No other cancer that is currently under treatment, clinically detectable, or has been
treated within the past 5 years (other than basal cell or squamous cell carcinomas)

- At least 6 months since prior and no concurrent participation in other invasive or
drug studies

- No radiotherapy or chemotherapy within 4 weeks of endoscopic tissue sampling

- At least 24 hours since prior and no concurrent nonessential medications or
nonsteroidal anti-inflammatory drugs

- No concurrent resveratrol-containing food and drink (e.g., wine, grapes, peanuts,
mulberries, cranberries, blueberries, huckleberries)

- No concurrent vitamin supplements

- No concurrent chronic medications, including over-the-counter medications, that may
interfere with the pharmacokinetics or pharmacodynamics measured

- No concurrent medication that could interfere with biomarker assay

- No concurrent anticoagulants including, warfarin and low molecular weight heparin

- No concurrent steroids
