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. ^{1 2 3 4 5}

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. ^{2 4 5 6 7}

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. ^{1 2 3 4 6}

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+ Placebo Experimental Treatment 2 Interventions

Morning light version and placebo capsule (3hrs before DLMO)

Group II: Morning light version+ Melatonin Experimental Treatment 2 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.

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.

Bright light therapy shows potential as an effective treatment for improving disordered eating behaviors and mood in individuals with eating disorders, based on a systematic review of 14 studies.

The exact timing of symptom improvement and the duration of treatment effects are still unclear, indicating a need for further research to better understand how bright light therapy works and its long-term efficacy.

In a study of 34 female outpatients with bulimia nervosa, those receiving 10,000 lux bright light therapy experienced a significant reduction in binge frequency compared to those receiving a placebo dim red light treatment.

Despite the improvement in binge eating behaviors, the study found no significant differences in depressive symptoms between the two groups, indicating that the light therapy specifically targeted binge eating rather than overall mood.

Bright light therapy decreases winter binge frequency in women with bulimia nervosa: a double-blind, placebo-controlled study. Braun, DL., Sunday, SR., Fornari, VM., et al.[2019]

In a study involving 10 patients with anorexia nervosa (AN) and 12 with anorexia nervosa and bulimic symptoms (AN + BN), the AN + BN group showed significantly higher daytime and nighttime levels of sulphatoxy-melatonin (aMT6s) compared to both the AN group and healthy controls, suggesting a potential link between melatonin output and the severity of symptoms.

The findings indicate that altered melatonin levels may reflect greater disruptions in circadian rhythms in patients with AN + BN, which could influence the progression of their illness, although no significant differences were observed between the two patient groups after 7 or 14 days.

Misalignment of food intake with our natural circadian rhythms can lead to serious health issues like obesity and disordered eating, particularly in evening-type individuals who tend to skip meals and eat late at night.

Chronotherapeutic interventions, such as bright light therapy, show promise in reducing disordered eating behaviors, but more research is needed to fully understand their effects on metabolic disorders and obesity-related eating issues.
