Safety and Tolerability Trial of Aripiprazole IM Depot Treatment in Adult Subjects With Schizophrenia Stabilized on Oral Antipsychotics Other Than Aripiprazole

This study will test the safety of an aripiprazole injection in subjects with schizophrenia that are currently taking oral antipsychotic medication other than aripiprazole. Subjects in this study will receive one injection of aripiprazole and will need to stop taking their other antipsychotic medication two weeks after the injection. The study will last one month. Subjects will be required to come to a clinic for evaluations and drug and urine collection five times during the course of the study.

Primary outcomes

  1. Number of Participants With Adverse Events (AE).

    Time frame: From the time the informed consent (ICF) was signed until follow-up at 30 days after the last trial visit (Day 28).

    An AE was defined as any new medical problem, or exacerbation of an existing problem, experienced by a participant while enrolled in the trial, whether or not it was considered drug related by the study physician. A serious adverse event (SAE) was any untoward medical occurrence that resulted in death or was life-threatening or required inpatient hospitalization or prolonged hospitalization. TEAE stands for treatment emergent adverse events.

Secondary outcomes

  1. Change From Baseline in Total Score of Positive and Negative Syndrome Scale (PANSS) for Observed Cases (OC) Data.

    Time frame: Baseline, Week 1, 2, 4 and Last visit (Day 28).

    The PANSS consisted of three subscales: a total of 30 symptom constructs. For each symptom construct, severity was rated on a 7-point scale, with a score of 1 (absence of symptoms) and a score of 7 (extremely severe symptoms). The PANSS total score was the sum of the rating scores for 7 positive scale items, 7 negative scale items, and 16 general psychopathology scale items from the PANSS panel. The PANSS total score ranged from 30 (best possible outcome) to 210 (worst possible outcome).

  2. Change From Baseline in Total Score of PANSS for Last Observation Carried Forward (LOCF) Data.

    Time frame: Baseline, Week 1, 2 and 4

    The PANSS consisted of three subscales: a total of 30 symptom constructs. For each symptom construct, severity was rated on a 7-point scale, with a score of 1 (absence of symptoms) and a score of 7 (extremely severe symptoms). The PANSS total score was the sum of the rating scores for 7 positive scale items, 7 negative scale items, and 16 general psychopathology scale items from the PANSS panel. The PANSS total score ranged from 30 (best possible outcome) to 210 (worst possible outcome).

  3. Change From Baseline in PANSS Positive Sub-scale Score for OC Data.

    Time frame: Baseline, Week 1, 2, 4 and Last visit (Day 28).

    The Positive and Negative Syndrome Scale (PANSS) consisted of three subscales: a total of 30 symptom constructs. For each symptom construct, severity was rated on a 7-point scale, with a score of 1 (absence of symptoms) and a score of 7 (extremely severe symptoms). The PANSS positive subscale score was the sum of the rating scores for the 7 positive scale items from the PANSS panel. The 7 positive symptom constructs are delusions, conceptual disorganization, hallucinatory behavior, excitement, grandiosity, suspiciousness/persecution, and hostility. The PANSS total score ranged from 30 (best possible outcome) to 210 (worst possible outcome).

  4. Change From Baseline in PANSS Positive Sub-scale Score for LOCF Data.

    Time frame: Baseline, Week 1, 2 and 4

    The PANSS consisted of three subscales: a total of 30 symptom constructs. For each symptom construct, severity was rated on a 7-point scale, with a score of 1 (absence of symptoms) and a score of 7 (extremely severe symptoms). The PANSS positive subscale score was the sum of the rating scores for the 7 positive scale items from the PANSS panel. The 7 positive symptom constructs are delusions, conceptual disorganization, hallucinatory behavior, excitement, grandiosity, suspiciousness/persecution, and hostility. The PANSS total score ranged from 30 (best possible outcome) to 210 (worst possible outcome).

  5. Change From Baseline in PANSS Negative Sub-scale Score for OC Data.

    Time frame: Baseline, Week 1, 2, 4 and Last visit (Day 28).

    The PANSS consisted of three subscales: a total of 30 symptom constructs.

The PANSS negative subscale score was the sum of the rating scores for the 7 negative scale items from the PANSS panel. The 7 negative symptom constructs: blunted affect, emotional withdrawal, poor rapport, passive apathetic withdrawal, difficulty in abstract thinking, lack of spontaneity and flow of conversation, stereotyped thinking. The PANSS total score ranged from 30 (best possible outcome) to 210 (worst possible outcome).

  6. Change From Baseline in PANSS Negative Sub-scale Score for LOCF Data.

    Time frame: Baseline, Week 1, 2 and 4

    The PANSS consisted of three subscales: a total of 30 symptom constructs.

  7. Change From Baseline in Clinical Global Impression Severity (CGI-S) Score in OC Data.

    Time frame: Baseline, Week 1, 2, 4 and Last visit (Day 28).

    The severity of illness for each participant was rated using the CGI-S scale. To assess CGI-S, the study physician answered the following question: "Considering your total clinical experience with this particular population, how mentally ill is the participant at this time?" Response choices included: 0 = not assessed; 1 = normal, not ill at all; 2 = borderline mentally ill; 3 = mildly ill; 4 = moderately ill; 5 = markedly ill; 6 = severely ill; and 7 = among the most extremely ill participants.

  8. Change From Baseline in CGI-S Score in LOCF Data.

    Time frame: Baseline, Week 1, 2 and 4.

    The severity of illness for each participant was rated using the CGI-S scale. To assess CGI-S, the rater or investigator answered the following question: "Considering your total clinical experience with this particular population, how mentally ill is the participant at this time?" Response choices included: 0 = not assessed; 1 = normal, not ill at all; 2 = borderline mentally ill; 3 = mildly ill; 4 = moderately ill; 5 = markedly ill; 6 = severely ill; and 7 = among the most extremely ill participants.

  9. Clinical Global Impression Improvement (CGI-I) Scale Score in OC Data.

    Time frame: Week 1, 2, 4 and Last visit (Day 28).

    The efficacy of trial medication were rated for each participant using the CGI-I scale. The study physician must rate the participant's total improvement whether or not it is due entirely to drug treatment. All responses were compared to the participant's condition a baseline. Response choices include: 0 = not assessed; 1 =very much improved; 2 = much improved; 3 = minimally improved; 4 = no change; 5 =minimally worse; 6 = much worse; and 7 = very much worse.

  10. CGI-I Scale Score in LOCF Data.

    Time frame: Week 1, 2 and 4

    The efficacy of trial medication were rated for each participant using the Clinical Global Impression Improvement (CGI-I) scale. The study physician must rate the participant's total improvement whether or not it is due entirely to drug treatment. All responses were compared to the participant's condition a baseline. Response choices include: 0 = not assessed; 1 =very much improved; 2 = much improved; 3 = minimally improved; 4 = no change; 5 =minimally worse; 6 = much worse; and 7 = very much worse.
