Schizophrenia
Conditions
Brief summary
The purpose of this study is to identify if there are self-reported/caregiver reported or objective measures that can predict near-term relapse (within 1 month or at another identified time point before meeting the criteria for relapse) or early symptomatic changes indicative of pre-relapse.
Interventions
DRUGOral Antipsychotics (OAP)
This is an observational study. Participants enrolled in this study will continue to receive routine treatment of OAPs for example, risperidone (1 to 6 mg OD to BID), olanzapine (5 to 20 mg OD), haloperidol (5 to 20 mg OD to TID) etc, as directed by their treating physician.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants with Relapse | Up to Approximately 3 years | Relapse is defined as achieving any of the following: clinically meaningful worsening of symptoms as determined by the treating physician's judgment; involuntary or voluntary admission to a psychiatric hospital for decompensation of the participant's schizophrenic symptoms (psychiatric hospitalization); deliberate self-injury and/or violent behavior resulting in clinically significant injury to the participant or another person or property damage; suicidal or homicidal ideation and aggressive behavior considered as clinically significant (in frequency and severity) in the treating physician's judgment; an increase of at least 2 points from the lowest reported Clinical Global Impression-Severity (CGI-S) score (ranging from 1 \[not ill\] to 7 \[extremely severe\]) captured either at baseline or post baseline. Number of participants with relapse will be determined. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants in each Clinical State of Schizophrenia | Up to approximately 3 years | Number of participants in each clinical state (Acute, Stable, and Remission) of schizophrenia will be assessed. The clinical states are defined as: 'Acute' - Clinical Global Impression-Severity (CGI-S) score (ranging from 1 \[not ill\] to 7 \[extremely severe\]) greater than or equal to (\>=)5 anytime during the study; 'Stable' (Tier I) - control of acute symptoms, defined as having a CGI-S score of less than or equal to (\<=)3 for a minimum of 3 months and/or (Tier II) - stable dosage of oral antipsychotic (OAPs) for a minimum of 3 months and control of acute symptoms, defined as having a CGI-S score of \<=4 for a minimum of 3 months; and 'Remission' - a continuous CGI-S scale score of \<=2 for 6 months. |
