Melatonin Versus Placebo and the Effect on Appetite in Advanced Cancer Patients

December 7, 2012 updated by: M.D. Anderson Cancer Center

A Randomized Clinical Trial of Melatonin Versus Placebo and the Effect on Appetite in Advanced Cancer Patients

The goal of this clinical research study is to evaluate the effectiveness of melatonin for the management of poor appetite and weight loss in advanced cancer patients. The effectiveness of melatonin on weight gain, keeping/gaining of lean muscle mass, improved appetite, and side effects will also be evaluated.

Detailed Description

Melatonin is a hormone that is made by the part of the brain called the pineal gland and may help in letting your body know when it is time to go to sleep and when it is time to wake up. The researchers feel melatonin might help to improve your appetite, improve your overall sense of well-being, and maintain your current weight.

If you are found to be eligible to take part in this study, you will see a nutritionist at the first (baseline) visit. The nutritionist will measure the amount of calories you consume. You will be asked to report all food and drinks you have had in a 3-day period. If you are unable to remember what you have eaten and drunk in the last 3 days, you will be asked by the nutritionist to list all the food and drinks you have had within the last 24 hours.

Your arm muscle diameter and your skin fold below your shoulder blade will be measured on the arm you don't normally use to write with. This is to determine your body fat, lean mass and water content of your body.

Your resting energy expenditure will be measured. You will be asked to wear a breathing mask and to blow into a tube. This will allow your breath to be analyzed, to measure how many calories your body is using while you are at rest.

Blood (about 1-2 tablespoons) will be drawn for tests to make sure there are no other treatable causes for your weight loss.

This blood test may not need to be repeated if you have had a blood test in the last 3 months.

If you are found to be eligible to take part in this study, you will be randomly assigned (as in the toss of a coin) to one of 2 groups. Participants in Group 1 will take melatonin daily before bedtime for 4 weeks. Patients in Group 2 will take a placebo daily before bedtime for 4 weeks. A placebo is a substance that looks like the study drug but which has no active ingredients. You will have an equal chance (50/50) of being placed in either group. Neither you nor any of the medical staff or researchers on this study will know if you are receiving the study drug or placebo.

On Week 2, you will return to the clinic and you will repeat all the tests done at the baseline visit. If you are unable to return to M. D. Anderson to complete the evaluations on Day 14 (± 2 days), the research nurse will contact you by telephone and ask you about any side effects you are experiencing.

At Week 4, you will return to the clinic and all the tests done at baseline will be repeated.

At the end of 4 weeks, all study patients in both groups will be given the opportunity to take melatonin before going to sleep at night for an additional 4 weeks. If you choose not to continue on melatonin for an additional 4 weeks, you will be taken off study and blood will be drawn for your end of study tests which include albumin, C-reactive protein (CRP), thyroid stimulating hormone (TSH), vitamin B-12, and cortisol. These tests will require about 1-2 tablespoons of blood to be drawn. If you choose to continue on melatonin for an additional 4 weeks, you will be asked to return to the outpatient clinic at Week 6 to repeat the tests done at baseline.

Your end of study tests will be done at the end of 8 weeks.

You will continue to visit the study doctor at the outpatient clinic as long he feels it is necessary. At these visits, your height and weight will be recorded and you will be asked what food and drinks you have had.

This is an investigational study. Melatonin is not currently approved by the FDA except to treat blind people with no light perception for sleep disorders-and is considered a food/nutritional supplement. Up to 126 patients will be enrolled at MD Anderson and at Duke University Medical Center in Durham, North Carolina.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Outcome Measure
Measure Description
Time Frame
Change in Appetite as Measured by ESAS
Time Frame: Baseline and at 4 weeks
Difference in ESAS (Edmonton Symptom Assessment Scale) assessment scores of appetite (symptom) from baseline evaluation [± 3 days] to 4 week evaluation [± 3 days], where the severity at the time of assessment is rated from 0 to 10 on a numerical scale; with 0 meaning that the symptom is absent and 10 that it is the worst possible severity.
