What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests if exposing patients with Binge Eating Disorder to morning light and giving them a Melatonin pill can help reset their body clock and reduce binge eating. Melatonin is a hormone involved in appetite regulation and food intake, and its supplementation has been studied for its potential to restore balance in cases of circadian disruption. The study focuses on obese adults aged 18-50.

Will I have to stop taking my current medications?

You may need to stop taking certain medications that affect the circadian system, like B-blockers, hypnotic sedatives, anticoagulants, antidiabetes drugs, oral corticosteroids, and other immunosuppressants. If you are on these medications, you should discuss with the trial team to see if adjustments are needed.

Is bright light therapy safe for humans?

Bright light therapy is generally considered safe for humans, as it is a noninvasive treatment used for various conditions, including eating disorders. Studies have shown it can be used without significant adverse effects.12345

How does the circadian rhythm intervention treatment differ from other treatments for binge eating disorder?

This treatment is unique because it focuses on regulating the body's natural 24-hour cycle (circadian rhythm) to address binge eating disorder, using methods like bright light exposure to improve mood and eating patterns. Unlike traditional treatments that may focus solely on behavior or nutrition, this approach targets the underlying biological rhythms that can contribute to disordered eating.24567

What data supports the effectiveness of the treatment for Binge Eating Disorder?

Research suggests that bright light therapy, a component of the treatment, can reduce binge eating episodes in individuals with eating disorders by helping to regulate circadian rhythms, which are often disrupted in these conditions.12346

Are You a Good Fit for This Trial?

This trial is for adults aged 18-50 with a BMI of ≥30 kg/m2 and diagnosed with moderate to severe Binge Eating Disorder (BED) as per DSM-5 criteria. Participants should not be on any new BED medication or have started psychotherapy within the last 2 or 3 months, respectively. Other moderate psychiatric conditions are allowed if stable, and effective contraception must be used by those who can bear children.

Inclusion Criteria

Current BED diagnoses by Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5) criteria confirmed by Structured Clinical Interview (SCID-5)
Moderate or severe BED (≥3 binge eating episodes/week in the past 14 days)
I have been in stable psychotherapy for 3 months and will continue it during the study.

Timeline for a Trial Participant

Screening

Participants are screened for eligibility to participate in the trial

2-4 weeks

Observational Phase

Circadian system function is evaluated in 80 adult obese subjects, 40 with BED and 40 without BED as a control group.

2 weeks
1 visit (in-person)

Treatment

A 4-week double-blinded, randomized, sham/placebo controlled study to evaluate the effect of morning lights and Melatonin/placebo on the circadian system and eating behavior.

4 weeks
Multiple visits (in-person and virtual)

Follow-up

Participants are monitored for safety and effectiveness after treatment

4 weeks

What Are the Treatments Tested in This Trial?

Interventions

  • Melatonin
  • Morning light version 1
  • Morning light version 2
  • Placebo
Trial Overview The study tests whether interventions like melatonin taken before the body's natural dim light melatonin onset (DLMO), or exposure to morning light therapy can help manage BED by targeting circadian system dysfunction. It compares these treatments against a placebo to see which is more effective.
How Is the Trial Designed?

Group I: Morning light version+ PlaceboExperimental Treatment2 Interventions
Morning light version and placebo capsule (3hrs before DLMO)
Group II: Morning light version+ MelatoninExperimental Treatment2 Interventions
Morning light version and melatonin 3mg capsule (3hrs before DLMO)

Published Research Related to This Trial

In a study involving 34 females with binge-eating disorder and bulimia nervosa, morning bright light exposure significantly reduced binge eating and food preoccupation for those with high dietary restraint and negative affect.
These results suggest that morning bright light could be an effective complementary treatment for individuals with binge-spectrum eating disorders, particularly for those who are harder to treat due to their specific psychological profiles.
Responses to bright light exposure in individuals with binge-spectrum eating disorders characterized by high dietary restraint and negative affect.Kambanis, PE., Bottera, AR., De Young, KP.[2023]
Individuals with eating disorders often experience disrupted eating rhythms, characterized by delayed mealtime peaks and atypical hunger patterns, which may lead to binge-eating episodes later in the day.
The proposed biobehavioral circadian model suggests that circadian disruptions play a significant role in the development and maintenance of restrictive and binge eating behaviors, indicating that interventions aimed at regulating circadian rhythms could enhance the effectiveness of existing eating disorder treatments.
A biobehavioral circadian model of restrictive eating and binge eating.De Young, KP., Bottera, AR.[2022]
Women with Binge Eating Disorder (BED) showed significant differences in their circadian rhythm compared to a control group, with reduced MESOR and Amplitude, but improved sleep quality after undergoing a structured multidisciplinary therapy.
The study, which included 28 women (14 with BED and 14 controls) monitored over 5 days, found that the BED group had better synchronization of their rest-activity rhythms and higher sleep efficiency, suggesting that a regular lifestyle can positively impact sleep patterns in patients with eating disorders.
