Brief Summary

Binge eating disorder (BED) shows prominent circadian features that suggest a delay in circadian phase, and preliminary evidence shows binge eating may be responsive to chronobiological interventions, implicating a circadian system dysfunction in its pathophysiology. What remains lacking, however, is comprehensive knowledge of the characteristics of circadian system dysfunction in BED, and whether this dysfunction represents a therapeutic target in BED. There is therefore a critical need to characterize circadian system dysfunction in BED, and evaluate it as a potential therapeutic target. Without such information, the understanding on the role of the circadian system in BED and its potential as a new therapeutic target will remain limited.

Outcome Measures

Primary Outcomes (2)

  • Phase 1 Dim Light Melatonin Onset (DLMO)

    Difference in mean DLMO (measured in time) between subjects with binge eating disorder (BED) and control subjects without BED.

    Phase 1 baseline (visit 0)

  • Phase 2 Dim Light Melatonin Onset (DLMO)

    Differences in DLMO (measured in time) change from baseline to endpoint between two intervention groups will be analyzed using an ANCOVA model with age as a covariate.

    Phase 2 baseline (visit 0) to endpoint, on average one month.

Secondary Outcomes (7)

  • Phase 1 Locomotor activity acrophase

    Phase 1 baseline (visit 0)

  • Phase 1 Midline Estimating Statistic of Rhythm (MESOR)

    Phase 1 baseline (visit 0)

  • Phase 1 MEQ

    Phase 1 baseline (visit 0)

  • Phase 1 Association between DLMO and binge eating days/week

    Phase 1 baseline (visit 0)

  • Phase 2 Binge eating days/week

    Phase 2 baseline (visit 0) to endpoint, on average one month.

  • +2 more secondary outcomes

Eligibility Criteria

Age18 Years - 50 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Age 18-50 years, inclusive
  • Female or male
  • BMI ≥30 kg/m2

  • Moderate or severe BED (≥3 binge eating episodes/week in the past 14 days)
  • No current pharmacological treatment for BED, or if receiving treatment dose stable for ≥ 2 months
  • If receiving psychotherapy, intervention must be stable for ≥ 3 months and agree to continue during the study
  • Other psychiatric disorders will be permitted as long as they are not more than moderate in severity
  • Using an effective contraceptive method (participants of childbearing potential)

You may not qualify if:

  • Current severe comorbid psychopathology (i.e; mania, severe major depressive disorder (MDD), psychosis)
  • Current (past month) substance use disorder (caffeine and nicotine allowed)
  • Chronic use of bright light therapy (BLT) or melatonin in the past month
  • Current contraindication or history of melatonin allergy or non-tolerability;
  • Current contraindication or history of BLT non-tolerability
  • Significant risk of suicide according to Columbia-Suicide Severity Rating Scale (CSSRS) or clinical judgment, or suicidal behavior in the past year
  • Routine shift work (night work) in the past month
  • Travel across more than 1 time zone in the past two weeks
  • Current treatment with medication known to affect the circadian system or melatonin measurements, including: B-blockers, hypnotic sedatives, anticoagulants, antidiabetes drugs, oral corticosteroids, and other immunosuppressant medication
  • Current lesions or bleeding in the oral cavity, as it may alter DLMO measurements
  • Clinically significant unstable medical conditions as judged by the clinician, including: seizure or neurodegenerative disorders, thyroid conditions, autoimmune disorders, and cardiovascular disease
  • Pregnancy or breastfeeding
  • Participation in a clinical trial in the past month
  • Suspected intelligence quotient (IQ) \<80
  • Any other clinically relevant reason as judged by the clinician

Masking Details
On the intervention phase 2 (Specific aim 2). Only subjects with BED (n=40) will participate and be randomly assigned to one of two combinations of morning lights and/or melatonin/placebo (20 subjects/each arm). Researchers and participants will be blinded to the intervention.
Purpose
BASIC SCIENCE
Intervention Model
PARALLEL
Model Details: The specific aims will be completed in a two-phase experimental approach. In the first phase (specific aim 1), subjects with obesity with BED (n=40) and without BED (n=40) will participate in a 2-week longitudinal study. In the second phase (specific aim 2), only BED subjects that complete phase 1 will rollover for a 4-week intervention study.
