About this study

Official title: Effects of Seroquel on Sleep Architecture in Patients With Bipolar Depression or Major Depressive Disorder - An Open Label Study

Clinical practice indicates that Quetiapine has sedating properties, and its sedative effects may play an important role in restoring quality of sleep in patients with various psychiatric conditions who frequently experience sleep disturbances as part of their illness. It is well known that depressive disorders are very frequently associated with significant sleep disturbance. Sleep disruption is a feature of Bipolar Disorder during both Depressed and Manic/Hypomanic episodes. Considering that Seroquel has good antidepressant properties (Calabrese, 2004), the investigators suggest that Seroquel's effect on sleep architecture contributes to its antidepressant properties.

Read the detailed description

Primary Objective:

To assess the objective (polysomnographic) change in sleep quality before and after introduction of Seroquel (Quetiapine) in treatment of patients with Bipolar Depression or Major Depressive Disorder.

Secondary Objectives:

To assess the objective (polysomnographic) and subjective changes in sleep quality parameters before and at different stages after introduction of Seroquel (Quetiapine) treatment, longitudinally, and to correlate these changes with measures of illness severity.

Study Design:

Prospective polysomnographic (PSG) study of patients before and after treatment with Seroquel (Quetiapine). PSG recordings will be done three (optional four) times during the study: before starting the Seroquel (Quetiapine) (baseline), at day 2 to 4 (early) and day 21 to 28 (longer term). (Optional fourth PSG can be done at day 42-56). PSG will be completed at patients home with a portable PSG.

The record says: finished, as of the sponsor's last update on 16 Dec 2015. 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 Canada. 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?

Sleep quality as measured by overnight PSG. (time frame: baseline, day 2 to 4 (early) and day 21 to 28 (longer term). Optional reading at day 42-56). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 16 Dec 2015.
