Purpose:

The major goal of this project is to investigate established insomnia treatments in a schizophrenia population to see if the improved sleep leads to overall better quality of life. In addition, we hypothesize that the insomnia treatment may also lead to observed improvements in other symptoms associated with schizophrenia such as cognitive impairments, obesity, and negative symptoms.


Study summary:

The primary aim of this study is to investigate the clinical efficacy of eszopiclone for the treatment of schizophrenia-related insomnia over 8 weeks. A two-week, single-blind placebo phase followed the double-blind phase to evaluate rebound and withdrawal effects after abrupt discontinuation.

Exclusion Criteria: - Meet criteria for current alcohol or other substance dependence - A history of dementia, mental retardation or other neurological disorder - Not capable of giving informed consent for participation in this study. - Ongoing pregnancy - Known sensitivity to zopiclone. - Insomnia associated with medical disorders likely to impair sleep. - Use of any medication that affects sleep/wake function (other than antipsychotic medication), within the past 2 weeks or within a time period that is less than 7 half-lives since last use of the medication. - Lack of sleep benefit from previous adequate eszopiclone treatment - History of clinically significant hepatic impairment. - Subject is taking a potent cytochrome p450 3A4 inhibitor medication (ritonavir, nelfinavir, indinavir, erythromycin, clarithromycin, troleandomycin, ketoconazole, itraconazole) and is unwilling or it is clinically contraindicated to stop the medication.
