Once-Daily Asenapine for Schizophrenia
Study Details
Study Description
Brief Summary
The investigators propose to explore: 1. the acceptance by patients of once versus twice daily dosing with asenapine, 2. the acceptance by staff of once versus twice daily dosing with asenapine, and 3. the changes in psychopathology associated with these two dosing strategies, in 30 patients with schizophrenia or schizoaffective disorder.
The investigators hypothesize that patient and staff acceptance will be better with once daily dosing and that improvements in psychopathology will be similar across once daily and twice daily dosing

Phase 4 |
Detailed Description
The investigators will randomly assign 30 patients newly admitted to Central Regional Hospital (CRH) for a psychotic exacerbation of schizophrenia or schizo-affective disorder to 14 days of treatment with either asenapine 5 mg BID or asenapine 10 mg QHS.
The investigators will assess patient and staff acceptance on day 14. The investigators will assess staff acceptance on day 14. The investigators will assess changes in psychopathology (Brief Psychiatric Rating Scale) from baseline to day 14.
The investigators propose to achieve the following specific aims:
-
To compare the patient acceptance of once daily versus twice daily asenapine; The investigators hypothesize that patient acceptance will be better for asenapine 10 mg QHS than for asenapine 5 mg BID at day 14
-
To compare the staff (medication nurses) acceptance of once daily versus twice daily asenapine; the investigators hypothesize that staff acceptance will be better for asenapine 10 mg QHS than for asenapine 5 mg BID at day 14
-
To compare the changes in psychopathology with once daily versus twice daily asenapine; the investigators hypothesize that changes in psychopathology from baseline to day 14 will be similar for the two dosing strategies

Drug: Asenapine 10 mg daily in the evening
The total daily dose of Asenapine will be given once daily in the evening
Other Names:
|
Active Comparator: asenapine 5 mg twice daily Patients will receive asenapine 5 mg daily in the morning and 5 mg daily in the evening |
Drug: Asenapine 5 mg twice daily
Asenapine will be given in two doses, 5 mg in the morning and 5 mg in the evening, daily

Outcome Measures
Primary Outcome Measures
- Patient Acceptance [At day 14]
A Patient Acceptance Likert Scale (1= Very Acceptable to 7 = Completely Unacceptable, i.e., individual refuses further doses) will be administered to the patient by the Research Nurse on day 14 of treatment.
Secondary Outcome Measures
- Change in Brief Psychiatric Rating Scale (BPRS) Total Score [From baseline to day 14]
The BPRS will be completed by the Principle Investigator at baseline and at day 14. The BPRS has 18 items each rated 1-7 with 1 representing the lowest severity of symptoms and 7 representing the highest severity; thus the lowest and highest possible total scores are 18 and 126
