The purpose of the trial was to evaluate the efficacy, safety, and tolerability of an
intramuscular depot formulation of aripiprazole as maintenance treatment in patients with
schizophrenia.
The trial was designed into 4 treatment phases. Phase 1 was designed to allow for a patient
to be converted from their current antipsychotic treatment to oral non-generic aripiprazole
monotherapy (oral conversion phase from 4 to 6 weeks). During Phase 2, the patient was
stabilized on oral non-generic aripiprazole monotherapy (oral stabilization phase from a
minimum of 4 weeks to a maximum of 12 weeks). Once the patient was stabilized in Phase 2,
they entered Phase 3, the single-blind intramuscular (IM) depot aripiprazole stabilization
phase. The goal of the phase was to stabilize the patient on the IM depot aripiprazole
formulation for a minimum of 12 weeks to a maximum of 36 weeks. When the patient was
stabilized, they were eligible to be randomized into the double-blind IM depot maintenance
phase (Phase 4). During Phase 4, the patient was assessed for exacerbation of psychotic
symptoms and/or impending relapse for up to 52 weeks.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Time to Exacerbation of Psychotic Symptoms/Impending Relapse | A patient experienced an exacerbation of psychotic symptoms/impending relapse if they met any of the following 4 criteria. 1) Clinical Global Impression of Improvement score = 5 and either an increase on any of the following Positive and Negative Syndrome Scale (PANSS) items (conceptual disorganization, hallucinatory behavior, suspiciousness, unusual thought content) to a score > 4 with an increase of = 2 on that item since randomization or an increase on any of the same PANSS items to a score > 4 and an increase of = 4 on the same combined PANSS items since randomization, 2) Hospitalization due to worsening of psychotic symptoms, 3) Clinical Global Impression of Severity of Suicide (CGI-SS) score of 4 or 5 on Part 1 and/or 6 or 7 on Part 2, or 4) Violent behavior resulting in clinically significant self-injury, injury to another person, or property damage. | Baseline of the depot maintenance phase to the end of the study (Week 52) | |
Secondary | Percentage of Patients Meeting Exacerbation of Psychotic Symptoms/Impending Relapse Criteria | This is the key secondary Outcome Measure. | Baseline of the depot maintenance phase to the end of the study (Week 52) | |
Secondary | Percentage of Responders | A patient was considered to be a responder if all of the following criteria were met. 1) Outpatient status, 2) PANSS total score = 80, 3) Lack of specific psychotic symptoms on the PANSS as measured by a score of = 4 on each of the following items (possible scores of 1 to 7 for each item): Conceptual disorganization, suspiciousness, hallucinatory behavior, unusual thought content, and 4) Clinical Global Impression of Severity of Illness (CGI-S) = 4 (moderately ill) and 5) CGI-SS = 2 (mildly suicidal) on Part 1 and = 5 (minimally worsened) on Part 2. | Baseline of the depot maintenance phase to the end of the study (Week 52) | |
Secondary | Percentage of Patients Achieving Remission | A patient was considered to have achieved remission if they had a score of = 3 on each of the following 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), and lack of spontaneity (N6). | Baseline of the depot maintenance phase to the end of the study (Week 52) | |
Secondary | Mean Change From Baseline in the PANSS Total Score | The PANSS consists of 3 subscales (Positive Subscale, 7 constructs, scores ranged from 7-49, Negative Subscale, 7 constructs, scores ranged from 7-49, General Psychopathology Subscale, 16 constructs, scores ranged from 16-112) containing a total of 30 symptom constructs. For each symptom construct, severity was rated on a 7-point scale, with a score of 1 indicating the absence of symptoms and a score of 7 indicating extremely severe symptoms. The PANSS total score ranged from 30-210 with a higher score indicating more severe symptoms. A negative change score indicates improvement. | Baseline of the depot maintenance phase to the end of the study (Week 52) | |
Secondary | Mean Change From Baseline in the Clinical Global Impression - Severity (CGI-S) Score | The severity of illness for each patient was rated using the CGI-S. 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 patient 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 patients. The CGI-S score ranged from 0-7 with a higher score indicating greater illness. A negative change score indicates improvement. | Baseline of the depot maintenance phase to the end of the study (Week 52) | |
Secondary | Mean Change From Baseline in the PANSS Positive Subscale Score | The PANSS Positive Subscale consists of 7 symptom constructs (delusions, conceptual disorganization, hallucinatory behavior, excitement, grandiosity, suspiciousness/persecution, and hostility). For each symptom construct, severity was rated on a 7-point scale, with a score of 1 indicating the absence of symptoms and a score of 7 indicating extremely severe symptoms. Scores on each subscale ranged from 7-49 with a higher score indicating more severe symptoms. A negative change score indicates improvement. | Baseline of the depot maintenance phase to the end of the study (Week 52) | |
Secondary | Mean Change From Baseline in the PANSS Negative Subscale Score | The PANSS Negative Subscale consists of 7 symptom constructs (blunted affect, emotional withdrawal, poor rapport, passive pathetic withdrawal, difficulty in abstract thinking, lack of spontaneity and flow of conversation, stereotyped thinking). For each symptom construct, severity was rated on a 7-point scale, with a score of 1 indicating the absence of symptoms and a score of 7 indicating extremely severe symptoms. Scores on each subscale ranged from 7-49 with a higher score indicating more severe symptoms. A negative change score indicates improvement. | Baseline of the depot maintenance phase to the end of the study (Week 52) | |
Secondary | Mean Clinical Global Impression-Improvement (CGI-I) Score | The efficacy of the study medication was rated for each patient using the CGI-I scale. The rater or investigator rated the patient's total improvement whether or not it was due entirely to drug treatment. All responses were compared to the patient's condition at Baseline. Response choices included: 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. The CGI-I score ranged from 0-7 with a higher score indicating less improvement/worsening. | Baseline of the depot maintenance phase to the end of the study (Week 52) | |
Secondary | Time to Discontinuation | Time to discontinuation was defined as the date of randomization to the date of study discontinuation. | Baseline of the depot maintenance phase to the end of the study (Week 52) |
