Low Antioxidant Diet in Controlling Cachexia in Patients With Oropharyngeal Cancer Receiving Chemotherapy and Radiation Therapy
Study Details
Study Description
Brief Summary
RATIONALE: Eating a diet that is low in antioxidants may control cachexia in patients with oropharyngeal cancer.
PURPOSE: This randomized phase I trial is studying the side effects of a low antioxidant diet in controlling cachexia in patients with oropharyngeal cancer receiving chemotherapy and radiation therapy.

Phase 1 |
Detailed Description
OBJECTIVES:
Primary
- Determine the safety of the antioxidant-deficient diet (ADD) in controlling cachexia in patients with oropharyngeal cancer receiving chemoradiotherapy.
Secondary
-
Determine the safety of the ADD as measured by quality of life, peripheral DNA damage, and change in body weight.
-
Determine the effectiveness of the ADD on tumor growth and surrogate markers of tumor growth.
-
Determine whether the ADD is effective in improving the tumor cachexia syndrome in these patients.
-
Determine whether there is a serum metabolomic signature for the ADD.
OUTLINE: This a prospective, randomized, double-blind, placebo-controlled study. Patients are randomized to 1 of 2 treatment arms.
-
Arm I: Patients consume a standard diet 3 times a day for 8 weeks.
-
Arm II: Patients consume an antioxidant-deficient diet (ADD) 3 times a day for 8 weeks. Patients receive replacement vitamins in week 9.
All patients receive planned chemoradiotherapy in weeks 3-8.
Quality of life, body composition (by dual-energy x-ray absorptiometry), weight, and resting energy expenditure (by indirect calorimetry) are assessed at baseline and at week 8.
Blood samples are collected at baseline and at 8 weeks. Samples are evaluated for cytokine levels; evidence of DNA damage from peripheral blood lymphocytes; and serum signature characteristic to ADD by multinuclear MRI spectroscopy. Patients undergo a tumor biopsy in week 4 for research studies. Samples are collected and evaluated for generation of reactive oxygen species by using antibodies against oxidatively modified DNA and lipids; apoptosis using TdT-mediated dUTP nick-end labeling assay and classical morphological criteria; and levels of the tumor toxohormones lipid mobilizing factor and proteolysis inducing factor by real time-PCR, northern blotting, and western blotting methods.
After completion of study therapy, patients are followed once during weeks 9-12.
Study Design
Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Antioxidant-deficient diet (ADD)
|
Other: ADD
The ADD has a composition of 65% carbohydrate, 20% fat, and 15% protein. The diet will be completely depleted of vitamins A, E and beta-carotene; it will have 10 mg of vitamin C (6.5% of RDA) added per person per day
|
Placebo Comparator: Placebo
|
Other: Placebo
Jevity 1.5 (1.5 cal/mL) will be used for the placebo patients in this study. This will simulate the standard of care for patients not on the ADD. Jevity 1.5 is an isotonic, fiber-fortified, high-nitrogen liquid formula providing complete, balanced nutrition for patients requiring short- or long-term tube feeding, given once per day

Outcome Measures
Primary Outcome Measures
- Number of people with adverse events [70 days]
Estimate the safety of the antioxidant-deficient diet (ADD) by measuring the frequency of grade 3 or 4 adverse events, per CTCAE criteria
