Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The primary objective is to evaluate the efficacy of aripiprazole IM depot compared with oral aripiprazole, as measured by the proportion of subjects experiencing exacerbation of psychotic symptoms/impending relapse by the end of 26 weeks of treatment from the date of randomization in Phase 3, in schizophrenic patients who have maintained stability on oral aripiprazole for at least 8 weeks in Phase 2 of the study before initiating treatment with aripiprazole IM depot.;Secondary Objective: To evaluate the safety and tolerability of aripiprazole IM depot as maintenance therapy in patients with Schizophrenia.;Primary end point(s): The primary efficacy endpoint of this study is the proportion of subjects experiencing exacerbation of psychotic symptoms/impending relapse by the end of 26 weeks from the date of randomization in Phase 3, in schizophrenic patients who have maintained stability on oral aripiprazole for at least 8 weeks in Phase 2 of the study. Exacerbation of psychotic symptoms or impending relapse is defined as meeting any or all of the following four criteria: 1) CGI-Improvement of >= 5 (minimally worse) AND • an increase on any of the following individual PANSS items (conceptual disorganization, hallucinatory behavior, suspiciousness, unusual thought content) to a score > 4 with an absolute increase of >= 2 on that specific item since randomization OR • an increase on any of the following individual PANSS items (conceptual disorganization, hallucinatory behavior, suspiciousness, unusual thought content) to a score > 4 and an absolute increase of >= 4 on the combined four PANSS items (conceptual disorganization, hallucinatory behavior, suspiciousness, unusual thought content) since randomization. OR 2) Hospitalization due to worsening of psychotic symptoms (including partial hospitalization programs), but excluding hospitalization for psychosocial reasons. OR 3) CGI-SS of 4 (severely suicidal) or 5 (attempted suicide | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): The secondary efficacy endpoints for Phase 3 are as follows: • Time to exacerbation of psychotic symptoms/impending relapse (ie, defined as meeting criteria; see protocol) from the date of randomization in Phase 3 • Percentage of responders (ie, defined as meeting stability criteria; see protocol) at endpoint in Phase 3 • Percentage of subjects achieving remission, where remission is defined as a score of = 3 on each of the following specific PANSS items, maintained for a period of 6 months: delusions (P1), unusual thought content (G9), hallucinatory behavior (P3), conceptual disorganization (P2), mannerisms/posturing (G5), blunted affect (N1), social withdrawal (N4), lack of spontaneity (N6) Other efficacy endpoints evaluated for Phase 3 will include: • Mean change from baseline to endpoint in PANSS Total Score • Mean change from baseline to endpoint in CGI-S • Mean change from baseline to endpoint in PANSS positive and negative subscales • Mean CGI-I score at endpoint • Time to discontinuation due to all causes;Timepoint(s) of evaluation of this end point: Please refer to E.5.2 | — |
