E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this trial is to determine whether Risperdal* Consta* provides improved effectiveness over a 2 year period, measured by the proportion of subjects who experience a clinical exacerbation, as compared to oral atypical antipsychotics (risperidone, olanzapine, quetiapine, and where commercially available, aripiprazole and amisulpride) prescribed in a routine care setting for the treatment of subjects with schizophrenia. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives are to assess a) the effectiveness of Risperdal* Consta* as measured by symptom improvement PANSS (Positive and Nedgative Symptoms scale) and CGI-S/C) (Clinical Global Impression Severity / Change); b) use of health care resources and assessment of quality of life (Resource Utilization Questionnaire and Assessment Quality Of Life); c) time to first clinical exacerbation; d) number of clinical exacerbations calculated at 2 timepoints: occurring 12 weeks post randomization and the entire trial duration; e) proportion of clinical exacerbations for the entire trial period; f) evaluation of symptomatic remission over time g) Personal and Social Performance Scale (PSP), h) tolerability and safety (AIMS, AE, laboratory tests, vital signs, weight, waist and hip circumference and physical exam). |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary endpoint is the proportion of subjects who experience a clinical exacerbation. Clinical exacerbation will be defined as one of the following:
Hospitalization due to an exacerbation of subjects schizophrenia Subjects requiring a change from their current antipsychotic to another antipsychotic treatment or initiation of an adjunctive antipsychotic treatment
In addition, a clinical exacerbation will be defined as a 2-point worsening in CGI-S plus at least one of the following:
Emergency room visit due to an exacerbation of subjects schizophrenia Utilization of treatment team services (e.g. social worker, case manager, nurse, psychiatrist, family physician) Deliberate self-injury, in the opinion of the investigator Emergence of clinically significant suicidal or homicidal ideation Violent behaviour resulting in significant injury to another person or significant property damage Requiring an increase in dose of their existing antipsychotic medication as a result of poor symptom control
