Correcting Circadian Rhythms to Breakthrough in Bipolar Disorder

Phase 2

Delayed Sleep-Wake Phase Disorder
Bipolar Disorder

Behavioral: Behavioral sleep control
Behavioral: Behavioral sleep intervention
Registration Number
NCT06226025
Lead Sponsor
Leslie Swanson
Brief Summary

The purpose of this study is to test whether a dietary supplement (low-dose melatonin) commonly used to treat night owls, administered in conjunction with a behavioral sleep intervention, will help to shift the brain clock earlier and improve mood and sleep in bipolar disorder. Eligible participants will be randomized to receive melatonin plus a behavioral sleep intervention or placebo plus a behavioral sleep placebo.

The hypotheses for this study include:

* Melatonin plus behavioral sleep intervention (compared to placebo plus behavioral sleep placebo) will produce a greater advance of dim light melatonin onset (DLMO), between pre- and post-treatment.

* Melatonin (compared to placebo) will produce a greater reduction in Patient Health Questionnaire-9 score between pre- and post-treatment.

Detailed Description

Ten Participants that competed the randomized trial and were assigned to the placebo group (and meet eligibility) can participate in the open label part of this project. Participants will sign a separate consent for this open label part.

Primary Outcome Measures
NameTimeMethod
Change in time of Dim Light Melatonin Onset (DLMO) baseline (pre-treatment) to 4 weeks (post-treatment)4 weeks (after treatment period)

Onset of melatonin in dim light conditions as measured in saliva (also called DLMO). Time of DLMO is measured in clock time and change in time of DLMO is measured in hours. The change score is calculated as time at 4 weeks minus baseline time. Thus, positive scores indicate a shift towards a later onset of melatonin and negative scores indicate a shift towards an earlier onset of melatonin.

Secondary Outcome Measures
NameTimeMethod
Change in the Patient Health Questionnaire-9 (PHQ-9)Baseline, 4 weeks (after treatment period)

The PHQ-9 is a 9-item self-report scale to screen for symptoms of depression. Items are rated on a 4-point Likert scale from 0 (not at all) to 3 (nearly every day), with total scores ranging from 0 to 27, where higher scores indicate more severe depressive symptoms.
