Stabilizing Mood & Sleep With Blue Blocking Eyewear in Bipolar Disorder

Status Recruiting

Clinical Trial Summary

The study investigates whether add-on treatment with eyewear that blocks the short wavelengths of visible light (<500nm) reduces manic symptoms and improves sleep in patients receiving outpatient treatment as usual for bipolar disorder. When in a hypomanic or manic phase, participants will be randomized to receive add-on treatment with either blue blocking or low filtration eyewear from 18 PM to 8 AM daily for 7 days. After this initial intervention phase, the eyewear is used daily for 3 months in either antimanic dose (14 hours) or maintenance dose (2 hours before bedtime).

Clinical Trial Description

The study is a 2-arm single-blind RCT to assess the effects of blue blocking (BB) or clear glasses as an acute 7-day antimanic intervention and as a 3-month mood stabilizing maintenance intervention. BB or clear glasses will be applied in addition to outpatient TAU for BD. Participants will be recruited among patients treated for BD in specialized outpatient clinics within the Mental Health Center Copenhagen. The active intervention is BB-glasses that eliminate 99 % of light with a wavelength below 530 nm, whereas the clear glasses filter out only 15% of short wavelength light (low filtration (LF). Participation includes 3 months use of the designated eyewear along with daily electronic self-monitoring of mood, sleep and activity as well as participation in a 2-day baseline assessment and a total of 3 follow-up visits including clinical assessment interview, questionnaires, and actigraphic (48 hours) and pupillometric assessments at day 9, week 5 and week 15. Participants will be included during hypomanic or manic state and begin treatment with an antimanic dosage of 14 hours (6 PM - 8 AM) for 7 consecutive days. Subsequently, during the 3-month follow-up period, the dosage (hours using the glasses) can be adjusted according to the current state, with use for 14 hours during hypomanic/manic phases and 2 hours before bedtime during euthymic and depressive states. Outcome assessors will be blinded to the treatment assignment and patients will be informed that they are randomized to eyewear with either high or low filtration of light. Patients will be randomized on a 1:1 basis with stratification according to sex and outpatient clinic. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
