ClinicalTrials.gov Identifier:	NCT00064298

Purpose

RATIONALE: Chemoprevention therapy is the use of certain substances to try to prevent the development or recurrence of cancer. Fruit and vegetable extracts may be effective in preventing the recurrence or further development of head and neck cancer.

PURPOSE: This randomized phase II trial is studying how well fruit and vegetable extracts work in preventing the recurrence of stage I, stage II, stage III, stage IVA, or stage IVB head and neck cancer.

Condition	Intervention	Phase

Study Type:	Interventional
Study Design:	Treatment, Randomized, Double-Blind, Placebo Control
Official Title:	A Phase II Randomized Placebo Controlled, Double Blinded Trial To Evaluate The Effects Of Fruit And Vegetable Extracts On Intermediate Biomarkers In Head And Neck Cancer Patients

Primary Outcome Measures:

Expression of p27 cell cycle regulatory protein, associated with disease-free survival as measured by blood sample at baseline and week 12 [ Designated as safety issue: No ]

Secondary Outcome Measures:

Cell proliferation (Ki-67), DNA damage (strand breaks), and immune function (T-cell function) as measured by biopsy at baseline and week 12 [ Designated as safety issue: No ]
Tobacco and alcohol use as measured by head and neck baseline questionnaire and food frequency questionnaire at baseline and week 12 [ Designated as safety issue: No ]
Depression as measured by Center for Epidemiologic Depression scale and positive symptom subscale at baseline and week 12 [ Designated as safety issue: No ]
Serum carotenoids and antioxidant levels (vitamins A, C, and E) as measured by blood tests at baseline and week 12 [ Designated as safety issue: No ]

Estimated Enrollment:	200
Study Start Date:	January 2004
Estimated Primary Completion Date:	December 2009 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Arm I: Experimental Patients receive oral fruit and vegetable extracts twice daily.	Dietary Supplement: fruit and vegetable extracts Given orally
Arm II: Placebo Comparator Patients receive oral placebo twice daily.	Other: placebo Given orally

Detailed Description:

OBJECTIVES:

Compare the disease-free survival of patients with stage I-IV (including stage IVA and IVB) head and neck cancer treated with fruit and vegetable extracts vs placebo.
Compare the effect of these extracts on biomarkers (p27 expression, cell proliferation of Ki-67, DNA damage, and T-cell function) in these patients.
Correlate changes in biomarkers with other factors (e.g., site and stage of the original tumors, tobacco/alcohol use, or depression) in patients treated with these extracts.
Compare serum carotenoids and antioxidant levels (vitamins A, C, and E) at baseline and posttreatment in patients treated with these extracts.

OUTLINE: This is a randomized, placebo-controlled, double-blind study. Patients are stratified according to tobacco use (yes vs no), alcohol consumption (yes vs no), and tumor stage at diagnosis (I vs II vs III vs IVA vs IVB). Patients are randomized to 1 of 2 treatment arms.

Arm I: Patients receive oral fruit and vegetable extracts twice daily.
Arm II: Patients receive oral placebo twice daily. Treatment in both arms continues for 12 weeks in the absence of disease progression or unacceptable toxicity.

Patients are followed annually for 5 years.

PROJECTED ACCRUAL: A total of 200 patients (100 per treatment arm) will be accrued for this study within 18 months.
