Treatment Study Comparing Aripiprazole Once Monthly With Standard of Care Medication in Outpatients With Schizophrenia
Phase 4
- Conditions
- Schizophrenia
- Interventions
- Drug: Oral Antipsychotic (i.e. aripiprazole, risperidone, lurasidone, quetiapine, olanzapine, ziprasidone, etc)
- Registration Number
- NCT02282085
- Lead Sponsor
- Matt Byerly
- Brief Summary
This study compares aripiprazole once-monthly injection to standard of care oral antipsychotic medication in non-adherent outpatients with schizophrenia to see which treatment helps people take their medicine more regularly and have more positive outcomes.
It is hypothesized that non-adherent schizophrenia outpatients receiving aripiprazole once-monthly will be more likely to respond and have lower symptom severity over 3 months of treatment than those receiving standard of care oral antipsychotics.

If employing birth control, two of the following precautions must be used: vasectomy, tubal ligation, vaginal diaphragm, intrauterine device, birth control pill, birth control implant, birth control once monthly injections, condom, or sponge with spermicide.

- Has used an investigational agent or has participated in a clinical study with aripiprazole once monthly or any other antipsychotic once monthly preparation within 30 days of screening.
