Melatonin Treatment for Night-Eating Syndrome (MLT)

January 18, 2018 updated by: Cenk Tek, Yale University
This is an 8-week randomized, double-blind, placebo-controlled, parallel, fixed-dose pilot clinical trial to test the effectiveness of melatonin treatment versus placebo on symptoms of Night Eating Syndrome (NES). The investigators will also look at the effect of melatonin treatment on weight, metabolic parameters and sleep parameters in individuals with NES.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Night Eating Syndrome (NES) is a unique disorder characterized by a delayed pattern of food intake in which recurrent episodes of food consumption occurs after the evening meal and/or during nocturnal awakenings. Diagnostic criteria for NES include: (1) recurrent episodes of night eating, as manifested by eating after awakening from sleep or by excessive food consumption following the evening meal, (2) awareness of those eating episodes, and (3) significant distress or impairment caused by the disorder. Exclusion criteria are binge-eating disorder or another mental disorder, as well as medical disorders or medications that might better explain the disordered eating pattern. NES is also more common among patients with insomnia, eating disorders, and other psychiatric disorders. 100 participants with night eating syndrome will be recruited from the general population. They will be randomized to either a commercially available rapid-release formulation of melatonin (5 mg) or matching placebo capsules, that will be administered once a day for a total of 8 weeks. Participants will attend a screening appointment, a baseline assessment and additional research assessment visits every other week for the 8 weeks.

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Night Eating Syndrome Symptoms - Night Eating Symptom Scale (NESS) Total Score
Time Frame: 8 weeks
Change in total score for the Night Eating Symptom Scale (NESS) from baseline to endpoint. Scores range from 0-52. Lower scores are better than higher scores.
8 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in body weight in kilograms during study duration.
Time Frame: 8 weeks
Change in body weight in kilograms from baseline to endpoint.
8 weeks
Change in body mass index (BMI) during study duration
Time Frame: 8 weeks

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
