About this study

Official title: Gerandomiseerde en Gecontroleerde Studie Naar de Effecten Van Lichttoediening Met Een Hogere Kleurtemperatuur in Vergelijking Met de Standaard Lichttherapie in de Behandeling Van Winterdepressie

One of the most frequently investigated hypothesis of the pathophysiology underlying Seasonal Affective Disorder(SAD) or so called winterdepression is a disturbance of circadian rhythms. Since the circadian system is especially sensitive for the blue portion of the light spectrum, a new light therapy device with more blue light (blue enriched polychromatic light) was tested for its efficacy to treat SAD. In chronobiological terms this light is hypothesized to be more potent in inducing non-visual effects. In the present study fluorescent tubes that emit a high portion of short wavelength light on top of the normal wavelengths are tested for its superiority in treating SAD. This blue-enriched light (colour temperature 17000 ºK) is compared to standard light treatment (5000 º K) in SAD patients., The investigators hypothesise that blue- enriched light improve the therapeutic effects of light treatment leading to a higher response or the same response in a shorter time schedule compared to standard light treatment.

Questions about this trial

What is this clinical trial studying?

A study testing Original Energy Light, and Original Energy Light prototype in people with Seasonal Affective Disorder, run by University Medical Center Groningen at 1 site in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Jan 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

SIGH SAD depression observer rating (time frame: days 1, 8, 15, 22). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01048294, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jan 2010.
