Stabilizing Mood and Sleep With Blue Blocking Eyewear in Bipolar Disorder (BLUES)

May 6, 2024 updated by: Mental Health Services in the Capital Region, Denmark

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).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed 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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
