Design outcomes

Primary

MeasureTime frameDescription
Change from baseline to 2 hours post-first IM injection on the PANSS-EC2 hoursThe PANSS-EC comprises 5 items associated with agitation: poor impulse control, tension, hostility, uncooperativeness, and excitement; each scored 1 (minimum) to 7 (maximum). The PEC, the sum of these 5 subscales, thus ranges from 5 (absence of agitation) to 35 (extremely severe)

Secondary

MeasureTime frame
Percentage of Participants With 40% or Greater Percent Decrease in the PANSS-EC Total Score2 hours post-first IM injection
Proportion of participants receiving one, two, or three doses of study drug during 24-hour intramuscular treatment period24 hours
