Condition or disease | Intervention/treatment | Phase |
---|---|---|
Schizophrenia | Drug: Any FDA approved antipsychotic agent Drug: aripiprazole long acting injectable formulation | Phase 4 |
Approximately 40 U.S. sites will participate in the study in order to enroll approximately 500 patients over a year period. They will be recruited into two cohorts - the first episode cohort and the early phase (EP) cohort, with approximately 250 patients in each cohort. Enrollment of patients will be discontinued when the appropriate number for the target for each cohort is reached.
After providing written informed consent, patients will be screened for general eligibility by the clinical team at the site. Basic demographic data will be collected to determine suitability for inclusion into the study. The site will complete an information interview comprising data regarding symptomology and history, but the diagnosis of schizophrenia will fall to a centralized, remote blinded rater to enable consistency for eligibility.
Prescribers at sites in the clinician's choice arm can treat the patients in the manner most appropriate for that individual. Prescribers at sites in the Aripiprazole Once Monthly arm monthly will prescribe and administer the medication according to recommendations contained in the product labeling.
For a period of 2 years all subjects will receive bimonthly calls inquiring about visits to emergency rooms and hospitalization. At 4 month intervals information on use of services, insurance status, work, school attendance, and other service use outcomes will be assessed.

Drug: Any FDA approved antipsychotic agent
Investigators are free to choose the most appropriate treatment for their clients |
Experimental: Aripiprazole Once Monthly
Aripiprazole long acting injectable formulation, 400mg per dose is to be administered once monthly. Clients in the study will be followed for 2 years

- Time to First Hospitalization [ Time Frame: Hospitalizations assessed every 2 months from baseline to Month 24 ]Assessments are done using best available data and patient interviews
- Total Number of Psychiatric Hospitalizations Per Treatment Arm [ Time Frame: Measured every 2 months from baseline to month 24 ]Assessments are completed using best available data and patient interviews
- Brief Psychotic Rating Scale (BPRS) Total Score [ Time Frame: Measured at Month 12 and Month 24 ]The Brief Psychotic Rating Scale is an 18 item scale where each item is rated 1-7, the minimum total score is 18 and the maximum total score is 126. Higher scores indicate more severe symptoms.
- Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) Sum of Scores [ Time Frame: Measured at Month 12 and Month 24 ]Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) is a 12 item scale with a total score range of 0 to 321 with higher scores indicating better cognitive functioning
- Quality of Life (QLS) Total Score [ Time Frame: Measured at Month 12 and Month 24 ]Quality of Life (QLS) is a 21 item scale where each item is rated from 0 to 7, the minimum score is 0 and the maximum score is 126 with higher scores indicating better overall functioning.
