About this study

Official title: Efficacy of a Combination of Chronotherapeutics for the Treatment of Major Depressive Episode (MDE) With Insomnia: a Multicenter, Randomized, 2*2 Factorial, Double-blind, Placebo-controlled Trial

Major Depressive Disorder (MDD) affects 5% of the global population and is the second leading cause of disability worldwide. Despite the widespread use of antidepressants, 50-60% of patients do not respond adequately after 8 weeks of treatment. Insomnia, present in approximately 85% of individuals with MDD, is a frequent and persistent symptom that contributes to poor treatment outcomes. Targeting insomnia has been shown to enhance both symptom remission and functional recovery. In this context, combined therapeutic strategies are often used to optimize the antidepressant response. Among them, chronotherapeutic approaches, such as light therapy and prolonged-release melatonin, have demonstrated rapid antidepressant effects and are beneficial in regulating sleep and circadian rhythms. Light therapy shows an efficacy comparable to antidepressants and, when used in combination with them, can double treatment effectiveness. Melatonin is also recommended in the management of depression-related insomnia. This multicenter, randomized, double-blind, placebo-controlled trial with a 2x2 factorial design aims to evaluate the efficacy of two chronotherapeutic interventions, 8 weeks of active light therapy and 2 mg of prolonged-release melatonin-administered alone or in combination, on depressive symptom reduction at 8 weeks in adult patients with MDD and comorbid insomnia. The primary outcome is the change in Montgomery-Åsberg Depression Rating Scale (MADRS) score from baseline to week 8. All participants will receive antidepressant treatment and sleep hygiene education. This study proposes a novel therapeutic strategy combining pharmacological and non-pharmacological interventions to address both depression and insomnia, with the goal of improving outcomes, especially for the 40% of patients who do not adequately respond to antidepressants alone.

Read the detailed description

Major Depressive Disorder (MDD) affects approximately 5% of the global population and represents the second leading cause of disability worldwide. Despite the availability of pharmacological treatments, particularly antidepressants, their efficacy remains limited: nearly 50 to 60% of patients do not respond adequately after 8 weeks of treatment. One of the most common and persistent symptoms in MDD is insomnia, which affects about 85% of patients and frequently persists even after partial improvement of mood symptoms. Insomnia is not only a residual symptom but also a marker of poor prognosis and treatment resistance. Addressing sleep disturbances directly has been shown to enhance both symptomatic and functional remission in depression, making it a promising target for intervention.

In clinical practice, combination strategies are increasingly employed to improve therapeutic response, particularly in patients who are only partially responsive to antidepressant medication. Among these strategies, chronotherapeutic interventions, such as light therapy and prolonged-release melatonin, offer a compelling approach. These treatments have demonstrated rapid antidepressant effects, with some studies reporting clinical improvements as early as the first week of treatment. Additionally, both interventions are known to positively influence sleep quality and circadian rhythm regulation, which are often disrupted in depressive disorders.

Light therapy (LT), in particular, has shown efficacy comparable to that of antidepressants and works by synchronizing the sleep-wake cycle. When used in combination with antidepressants, LT has been associated with significantly greater reductions in depressive symptoms than antidepressants alone. Similarly, prolonged-release melatonin has been recommended in the management of insomnia comorbid with depression, further supporting the rationale for combining these chronotherapeutic agents.

This study is a multicenter, randomized, double-blind, placebo-controlled trial designed in a 2x2 factorial format. It aims to evaluate the efficacy of two chronotherapeutic interventions, active light therapy (10,000 lux) for 8 weeks and 2 mg prolonged-release melatonin for 8 weeks, administered alone or in combination, in improving depressive symptoms at 8 weeks. The trial will enroll adult patients diagnosed with moderate to severe MDD and comorbid insomnia. The primary objective is to assess the change in depressive symptom severity, measured by the Montgomery-Åsberg Depression Rating Scale (MADRS) score, from baseline to week 8.

All participants, regardless of group allocation, will receive standard antidepressant treatment and structured sleep hygiene counseling to ensure a consistent baseline of care. This approach reflects real-world practices and enhances the ecological validity of the trial. The study also incorporates objective and subjective measures of sleep and circadian rhythms to explore the broader impact of the interventions.

By evaluating the combined and individual effects of light therapy and melatonin alongside standard care, this study seeks to establish an innovative and comprehensive therapeutic model. The goal is to improve outcomes for individuals with MDD and insomnia, particularly the substantial proportion of patients, up to 40%, who do not achieve adequate response with antidepressants alone. This trial represents a significant step toward more personalized, effective, and integrated treatment strategies for depression.

What is this clinical trial studying?

A Phase 3 study testing AD + SHR + active LT and extended-release melatonin 2mg in people with Major Depressive Disorder (MDD) With Insomnia, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 12 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Pierre-Alexis GEOFFROY, Pr, med (+33 1 40 25 62 72, pierrealexis.geoffroy@aphp.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Assessment of the efficacy of two chronotherapeutics (LT and extended-release melatonin 2mg), alone or combined, associated to AD on depressive symptoms reduction after 8 weeks of treatment (time frame: At baseline (Week 0) and at Week 8). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Aug 2026.
