Brief summary
The objective with this study is to conduct a 6-month RCT comparing effects of add-on melatonin versus add-on placebo on mood stabilisation and other critical patient outcomes in patients with BD and to test whether principal effects are antimanic, antidepressant and/or prophylactic against relapse
Detailed description
Sleep abnormalities are common in all phases of bipolar disorder (BD) and constitute core symptoms of both depression and mania also during remitted phases and despite treatment. Melatonin is a key circadian hormone, that expresses a robust circadian rhythm and acts as an important endogenous modulator of the circadian timing system of sleep and may thus improve sleep and stabilize BD per se. Nevertheless, sleep in general and melatonin specifically is critically understudied in BD reflecting a central key knowledge gap within psychiatry. The investigators want in a 6-month randomized placebo-controlled trial (RCT) to compare effects of add on melatonin versus add on placebo on mood stabilisation and other critical patient outcomes in patients with BD.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Mood stabilization | 6 months | Mood stabilization will be measured by a mood instability score reflecting the daily variability in self-monitored mood collected via the Monsenso system. Patients score their daily mood on a 9-point scale (-3 to +3); scores between -0.5 to 0.5 reflect normal variations, whereas scores of +1, +2 or +3 correspond to mildly, moderately, and severely increased mood and scores of -1, -2 or -3 correspond to mildly, moderately, and severely decreased mood. According to our established methodology, for each participant, we will estimate a mood instability score. Estimates of instability will be based on reading obtained via the Monsenso system which will prompt patients to complete daily mood ratings. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Sleep | 6 months | Change in sleep measured by change from baseline on the Pittsburgh Sleep Quality Index (min. value = 0; max. value = 21 with higher scores indicating poorer sleep quality) on 3 months visit and 6 months visit |
| Depression | Changes between baseline, 3 months and 6 months | The clinical rating of depression is assessed using the Hamilton Rating Scale for Depression, 6 items (HAM-D6), (min. value=0; max. value = 22 with higher scores reflecting more severe depression ) |
