简要总结
To determine the safety and tolerability of multiple-dose administrations of aripiprazole intramuscular (IM) depot in the deltoid muscle in adult subjects with schizophrenia
详细描述
This is a trial designed to assess the safety and tolerability of multiple-dose administrations of aripiprazole intramuscular (IM) depot in the deltoid muscle in adult subjects with schizophrenia. The trial consists of a 113 day treatment period with a 28 day followup. The trial population will include male and female subjects between 18 and 64 years (inclusive), with a current diagnosis of schizophrenia as defined by DSM-IV-TR criteria and a prior history of tolerating aripiprazole per investigator's judgement.

结局指标
主要结局
Mean Change From Baseline Measured by EPS by Barnes Akathisia Rating Scale (BARS).
时间窗: Baseline to Week 20
The BARS consisted of 4 items related to akathisia: objective observation of akathisia by the study physician, subjective feelings of restlessness by the participant, participant distress due to akathisia, and global evaluation of akathisia. To complete this scale, participants were observed while they were seated and then stood for a minimum of 2 minutes in each position. Symptoms observed in other situations (e.g., while engaged in neutral conversation or engaged in activity on the ward) may also be rated. Subjective phenomena were to be elicited by direct questioning. The first 3 items were rated on a 4-point scale, with a score of 0 = absence of symptoms and a score of 3 = severe condition. The global clinical evaluation were made on a 6-point scale, (0=absent, 1=questionable, 2=mild, 3=moderate, 4=marked, 5=severe).
Number of Participants With Adverse Events (AEs).
时间窗: AEs were recorded from the time the informed consent was signed until follow-up for 28 days after last
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 investigator. 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. A treatment-emergent AE (TEAE) was defined as an AE that started after start of study medication or an AE that continued from baseline and that worsened, was serious, was study medication related, or resulted in death, discontinuation, interruption, or reduction of study medication.
Mean Visual Analog Scale (VAS) Score for Rating of Pain at the Injection Site.
时间窗: Days 1 and 113
Participants assessed the pain associated with injection of aripiprazole IM using the VAS instrument. This was done approximately 30 minutes pre-dose and 1 hour (±15 min) Post-dose on Days 1, 29, 57, 85 and 113. For the first injection, the pre-dose assessment was of the current injection site. For the injections 2 through 5, the pre-dose assessment was of the prior injection site. Investigator's Assessment of Most Recent Injection Site including pain, swelling, redness, and induration were reported in 4-point categorical scale (1 = absent, 2 = mild, 3 = moderate and 4 = severe) by first injection site at each injection.
Mean Change From Baseline in Suicidal Ideation Intensity Total Score Via Columbia-suicide Severity Rating Scale (C-SSRS).
时间窗: Baseline to Last Visit (Day 141)
Suicidality was monitored throughout the trial using C-SSRS. The C-SSRS addresses the need for standardized classification of suicide reports to assess suicide risk. This scale consisted of Baseline evaluation that assessed the lifetime experience of the participant with suicidal events and suicidal ideation and a post baseline evaluation that focuses on suicidality since the last trial visit. The C-SSRS since last visit form were completed on Day 1 pre-dose and prior to dosing on Days 29, 57, 85, 113, 141/ Early Termination(ET) and prior to pharmacokinetics(PK) sampling on Days 8, 15, 22, 120, 127 and 134. The suicidal ideation intensity total score was the sum of suicidal ideation severity rating scores for frequency, duration, controllability, deterrents, and reasons for ideation. For each item, each participant got an intensity score from 0(none) to 5(worst). Therefore,the suicidal ideation intensity total score range from 0 to 25, with a score of 0 given for no suicidal ideation.
Mean Change From Baseline Measured by Extrapyramidal Symptoms (EPS) by Simpson-Angus Scale (SAS).
时间窗: Baseline to Week 20
The SAS consisted of a list of 10 symptoms of Parkinsonism (gait, arm dropping, shoulder shaking, elbow rigidity, wrist rigidity, head rotation, glabella tap, tremor, salivation, and akathisia). The SAS Total Score was the sum of the scores for all 10 items. SAS total score can range from 10 to 50. Each item was rated on a 5-point scale, with a score of 1 =absence of symptoms and a score of 5 =severe condition.
Mean Change From Baseline Measured by EPS by Abnormal Involuntary Movement Scale (AIMS).
时间窗: Baseline to Week 20
The AIMS assessment consisted of 10 items describing symptoms of dyskinesia. Facial and oral movements (items 1 through 4), extremity movements (items 5 and 6), and trunk movements (item 7) were observed unobtrusively while the participant was at rest (e.g., in the waiting room), and the study physician would make global judgments on the participant's dyskinesia's (items 8 through 10). These items are rated on a five-point scale of severity from 0-4. The scale is rated from 0 (none), 1 (minimal), 2 (mild), 3 (moderate), 4 (severe). Overall AIMS scores range from 0 to 42.
