NCT00272597

Brief Summary

The primary objective of this pilot study is to evaluate the impact of switching 30 subjects from an existing antipsychotic to risperidone long acting on healthcare resource utilization. The study will be a ten month open-label, 'mirror-image', pilot study. Healthcare resource utilization during the 10 months prior to starting risperidone long acting will be retrospectively collected for all subjects (period A) at the beginning of the study. The utilization of direct medical resources will also be collected for 10 months after initiation of risperidone long acting (period B). In this design the patients will serve as their own control.

Outcome Measures

Primary Outcomes (5)

  • To assess the impact of switching subjects from an existing antipsychotic to risperidone long acting on healthcare resource utilization. This will be evaluated by assessing:

  • Direct cost of care

  • Frequency and duration of institutional care

  • Discharge

  • Relapse

Secondary Outcomes (12)

  • To determine if effectiveness is maintained for subjects switched from an existing antipsychotic to risperidone long acting. This will be evaluated by assessing:

  • Positive and negative symptoms (PANSS)

  • Overall illness severity (CGI severity, CGI improvement)

  • Social and occupational functioning (SOFAS), and

  • Remission

  • +7 more secondary outcomes

Study Arms (1)

Risperidone LAI

OTHER

Subjects treated with any antipsychotic can be switched to Risperidone LAI. * If the subject is currently treated with an antipsychotic other than risperidone, the dosage will be tapered gradually and discontinued. Simultaneously, oral risperidone will be started at 2 mg/day and increased to no more than 6 mg/day. The subject will be treated with risperidone monotherapy for at least five days prior to entering the stabilization phase of the study. * On the other hand, if the patient has already been treated for more than 5 days with risperidone monotherapy then he/she may enter the stabilization phase of the study immediately.

Drug: Risperidone

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subjects with a diagnosis of schizophrenia or schizoaffective disorder according to DSM-IV criteria.
  • Men and women, aged 18-65 years.
  • Subjects must be able to give written informed consent.
  • Subjects must be inpatients.
  • Subjects must have adequate data to assess healthcare resource utilization for the previous 10 months.
  • Subjects must have been previously treated with (and tolerated) oral risperidone.
  • Results of standard clinical laboratory tests are to be within the laboratory's reference range or, if outside this range, judged by the investigator to be not clinically significant.

You may not qualify if:
