SECONDARY outcome

Timeframe: up to 24 hours after the first IM injection

Population: Participants having a post-baseline measure, last observation carried forward (LOCF).

The ACES differentiates agitation, calmness, and sleep-state, using a 9-point scale: 1 (Marked Agitation) to 9 (Unarousable). Scores of 4 (Normal) to 7 (Marked Calmness) were used for this outcome measure.

SECONDARY outcome

Timeframe: Up to 24 hours after the first IM injection

Population: Participants with an abnormal value at post-baseline, last observation carried forward (LOCF).

Assesses extrapyramidal symptoms attributable to antipsychotics. Consists of 9 items (8 to assess individual symptoms; 1 to assess global severity). Each item is assessed from 0 (none, normal) to 4 (severe). Total points of 8 items are defined as DIEPSS total (0 to 32 points). Items for assessment of individual symptoms are classified into 4 categories of parkinsonism, akathisia, dystonia and dyskinesia. Parkinsonism is assessed by total points of items 1 to 5; akathisia, dystonia and dyskinesia are assessed by points given to corresponding items (item 6, item 7, and item 8, respectively).
