Trial Outcomes & Findings for A Study Comparing Rapid Acting Intramuscular Olanzapine and Placebo in Agitated Patients With Schizophrenia (NCT NCT00640510)

NCT ID: NCT00640510

Last Updated: 2009-09-02

Results Overview

Measures excitability and consists of the following 5 items from the PANSS: Excitement, Hostility, Tension, Uncooperativeness, and Poor Impulse Control. Each item is rated on a scale from 1 (Absent) to 7 (Extreme). The sum of the 5 items is defined as the PANSS-EC total score which ranges from 5 to 35.

Participant milestones
Measure
IM Olanzapine 10mg
Patients will receive at least one injection of Intramuscular olanzapine 10mg. If patients do not respond to the study medication or if patients do not have enough improvement based on the investigator's judgment, and in addition, if the investigator judges it is reasonable, the patient will receive a second injection at the same dose strength as the first injection after 2 hours following the first injection (no later than 8 hours after the first injection).
IM Placebo
Patients will receive at least one injection of Intramuscular placebo. If patients do not respond to the study medication or if patients do not have enough improvement based on the investigator's judgment, and in addition, if the investigator judges it is reasonable, the patient will receive a second injection at the same dose strength as the first injection after 2 hours following the first injection (no later than 8 hours after the first injection).

PRIMARY outcome

Timeframe: 2 hours post first intramuscular (IM) injection

Population: Number of randomized patients having the measures both at baseline and post-baseline. Last Observation Carried Forward.

Measures excitability and consists of the following 5 items from the PANSS: Excitement, Hostility, Tension, Uncooperativeness, and Poor Impulse Control. Each item is rated on a scale from 1 (Absent) to 7 (Extreme). The sum of the 5 items is defined as the PANSS-EC total score which ranges from 5 to 35.

Population: Number of patients having the measure at post-baseline. Last Observation Carried Forward.

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.
