Study summary

This study will be a randomized controlled trial (RCT) measuring the efficacy of wearing blue-blocking glasses (orange glasses) on manic symptoms in a population of patients suffering from Bipolar Disorder (BD), hospitalized for a manic episode on 10 days compared to non-filtering glasses (clear glasses, placebo) in addition to pharmacological treatment as usual.

The primary objective of this study is to evaluate the efficacity of orange glasses on improving manic symptoms in adult patients presenting BD in comparison with placebo. The primary outcome will be the change of total score of the Young Mania Rating Scale (YMRS) from baseline to day 10. Secondary objectives will be change in sleep quality, in motor activity (patterns of activity and rest), impact on psychotics symptoms, kinetics of the decrease of the manic symptoms from inclusion to the study and impact on maximal administered antipsychotic medication dosage ; they will be explored.

The investigators hypothesize that orange glasses is more effective than placebo in improving manic symptoms as an adjuvant treatment.

This project will take place in Alizé unit which is a newly conceived specialized ward dedicated to treating BD, at the HUG. The methodology has been developed in collaboration with the center of clinical research (CRC). The study will be conducted in accordance with established ethical and data management/protection practices.

Read the detailed description

The design of the study is a monocentric, single-blinded, two-arm parallel-group randomized placebo-controlled trial in a newly developed specialized mood disorder ward at the Geneva University Hospitals. The methodological aspects of this trial are elaborated in consultation with the Centre of Clinical Research (CRC) of our Hospital. The adjunctive treatment consists in wearing BBG for a few hours between 7pm and bedtime for ten days. Orange glasses (intervention) are from Melamedic®, type UV530 (Medical Device Class I - 93/42 EEC made in Denmark).

The adjunctive treatment will be compared to a placebo (clear-lensed glasses), both groups will also receive an active treatment as usual (the standard of care for treating manic episode following Swiss and international guidelines). No treatments are prohibited. All pharmacological treatments will be recorded. Due to the particularity of the device, the clinicians and the patient cannot be blind to the treatment condition (orange glasses vs clear glasses) which is an acknowledged limitation. The participants were masked to group assignment by receiving identical limited information about the purpose of the study : testing the effectiveness of different types of glasses in reducing manic symptoms by blocking different wavelengths of light. Patients will be randomized after eligibility has been established and written consent has been sought. If the patient capacity to consent is impaired, legal representative will be informed and capacity to consent will be re-assessed before each visit to obtain a written consent (delayed consent). Signs showing that the participant is unwilling to participate in the study will result in the participant exclusion (explicit refusal). The expected total duration of participation is 10 days. Data will be analyzed in an intention-to-treat design.

Exclusion criteria

Exclusion Criteria:

  • previous knowledge of blue-blocking glasses

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

DSM diagnostic criteria

The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.

What researchers measure

Primary outcomes

  1. Manics symptoms

    The primary endpoint will be the change of total score of the Young Mania Rating Scale (YMRS) from baseline to day 10. The YMRS is a checklist of 11 items that are ranked on a scale of 0-4 or 0-8, the latter anchoring given to the four items which can be rated even with patients with poor cooperation. The score range therefore is between 0 and 60. This scale is classically used to assess the effectiveness of the treatment on manic symptoms. This is a clinical interview scale to assess the severity of manic states primarily used for research and it is designed to measure the severity of manic states, it can help guide clinicians on treatment planning and progress. The investigators define a score of at least 20 points on the YMRS (\> 20) to identify a manic state and the lower the score, the more the patient is in a state of euthymia (scale \<2).

    Time frame: from baseline to day 10

Secondary outcomes

  1. Sleep quality

    The investigators aim to assess the sleep quality for each participant by the Pittsburgh Sleep Quality Index (PSQI) and hypothesize that the patients receiving the intervention will have a better sleep quality. The scale assesses a broad range of sleep domains and consists of 19 self-rated questions that measure seven components of sleep that are scored from 0 to 3: sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbance, use of sleep medication and daytime dysfunction. The global score is the combination of the seven sub-scores and ranges therefore from 0 to 21, with higher scores for worse sleep quality; the cut-off point to define "poor sleepers" is \>5.

    Time frame: from baseline to day 10

  2. Psychotics symptoms

    The investigators aim to assess the presence or absence of psychotics symptoms by the Positive and Negative Syndrome Scale (PANSS). The scale has mostly been used to inventory, grade and follow the symptoms in schizophrenia. It quantifies positive symptoms, which refer to an excess or distortion of normal functions (e.g., hallucinations and delusions), and negative symptoms, which represent a diminution or loss of normal functions. The PANSS is composed of 3 subscales: Positive Scale, Negative Scale, and General Psychopathology Scale. Each subscale is rated with 1 to 7 points ranging from absent to extreme. The range for the Positive and Negative Scales is 7-49, and the range for the General Psychopathology Scale is 16-112

    Time frame: from baseline to day 10

  3. Kinectics of the decrease of manics symptoms

    The investigators aim to assess the kinetics of the decrease of manics symptoms for each participtant and hypothesize that participants receiving the intervention will have a faster decrease in the Young Mania Rating Scale (YMRS).

    Time frame: from baseline to day 10

  4. Impact on maximal administred antipsychotic medication dosage

    The investigators aim to record the dosage of antipsychotic treatment for each patient and hypothesize that participants receiving the intervention will have lower dosage.

    Time frame: from baseline to day 10

  5. Measure of the motor activity

    The investigators aim to assess the intensity of the motor activity for each participant by actigraphy which is a noninvasive technique that measures physical activity levels of a subject by means of a wristwatch-like motion-sensing device that can be worn for prolonged periods of time. By use of a wrist-worn actigraph, motor activity will be continuously recorded for all groups. They will be compared to data from a healthy control group.

    Time frame: from baseline to day 10

Other outcomes

  1. Depressive symptoms

    The investigators aim to assess the incidence and severity of depressive symptoms (in manic episode) or aggravation of depressive symptoms (in manic episode with mixed features) by the Montgomery-Asberg Depression Rating Scale (MADRS). The rating should be based on a clinical interview moving from broadly phrased questions about symptoms to more detailed ones which allow a precise rating of severity. Each item has a severity scale from 0 to 6, with higher scores reflecting more severe symptoms. Ratings can be added to form an overall score (from 0 to 60). This is our cut-offs : scores of 0-6 indicate an absence of symptoms; 7-19 represent mild depression; 20-34 moderate; 35-60 indicate severe depression.

    Time frame: from baseline to day 10

  2. Side effects

    All adverse effects will be rigorously monitored during the whole study for each participant. Number of participants with treatment-related adverse events will be recorded if present.

    Time frame: from baseline to day 10
