Trial summary

This study will apply polysomnography (PSG) to evaluate the effect of quetiapine fumarate on sleep architecture. Most of previous studies evaluated sleep by self-reported questionnaires during the antipsychotic treatment (clozapine, risperidone, olanzapine, et al), while only a few studies with PSG evaluation had some… Read more about this study

About this study

Official title: Study of Evaluating Quetiapine in Improving Sleep Quality of Schizophrenia

This study will apply polysomnography (PSG) to evaluate the effect of quetiapine fumarate on sleep architecture. Most of previous studies evaluated sleep by self-reported questionnaires during the antipsychotic treatment (clozapine, risperidone, olanzapine, et al), while only a few studies with PSG evaluation had some limitation, such as: small sample size, respective or cross-sectional, potential sleep disorders, et al. In this study, we will investigate both subjective and objective effect of quetiapine fumarate in improving sleep quality in schizophrenic patients by PSG as well as psychiatric scales. The control drug in this study is the typical antipsychotic - haloperidol. It could increase sleep duration and efficiency by mostly increasing the S2 without effect on rapid eye movement (REM) sleep and slow wave sleep (SWS). The patients will be randomised into two groups as a parallel design. This study is designed as rater blinded to reduce the bias in evaluation. It is suggested that the sedative effect of quetiapine fumarate could diminish in 2 weeks, therefore, we use 4 weeks to ensure the change of sleep quality in this study, which could be helpful for the evaluation of relative short and middle term effect of quetiapine fumarate on sleep quality.

Read the detailed description
  1. The objective sleep structures of quetiapine fumarate and haloperidol being used as mono-therapy respectively in the treatment of patients with acute schizophrenia are measured by the change of composite variables for PSG test (sleep stages, time in bed, total sleep time, sleep efficiency, sleep latency) from baseline to Week 4 (LOCF).
  2. The subjective sleep qualities of quetiapine fumarate and haloperidol being used as mono-therapy respectively in the treatment of patients with acute schizophrenia are measured by the change of Pittsburgh Sleep Quality Inventory (PSQI) and Epworth Sleepiness Scale(ESS) from baseline to Week 4 (LOCF).
  3. The clinical efficacy of quetiapine fumarate and haloperidol being used as mono-therapy respectively in the treatment of patients with acute schizophrenia are measured by the change of Positive and Negative Syndrome Scale (PANSS) and Clinical Globe Impression (CGI),and Calgary Depression Scale for Schizophrenia (CDSS) from baseline to Week 4 (LOCF).
  4. The clinical safety and tolerance quetiapine fumarate and haloperidol being used as mono-therapy respectively in the treatment of patients with acute schizophrenia are measured by Treatment Emergent Symptom Scale (TESS) in day 14 and day 28.

  2. Percentage of Rapid Eye Movement Sleep

    The primary variable is the change of the percentage of rapid eye movement (REM)sleep from baseline to the 28th day (LOCF).

    Measured: 28 days

Questions about this trial

What is this clinical trial studying?

A study testing quetiapine fumarate and haloperidol in people with Schizophrenia, run by Guang Dong Provincial Mental Health Institute at 1 site in China.

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 6 inclusion and 21 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 17 Apr 2014. 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 China. 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?

Yes. Results are posted in the registry (first posted 17 Apr 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Percentage of Slow Wave Sleep (time frame: 28 days). The study lists 2 primary outcomes in all. 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 17 Apr 2014; AzTrials last refreshed its copy on 31 Oct 2026.
