26 août 2009 mis à jour par: Eli Lilly and Company

A Placebo-Controlled, Double-Blind Confirmatory Study of Rapid-Acting Intramuscular Olanzapine in Agitated Patients With Schizophrenia

The primary objectives of the study is to confirm if the efficacy of IM olanzapine in patients with schizophrenia is greater than IM placebo by comparing changes from baseline to 2 hours post first IM injection of agitation.

The investigator must believe that it is safe to administer IM olanzapine to the patients with respect to the safety profile, including the anticholinergic properties of Olanzapine IM.
  • Patients have a minimum total score of ≧ 20 on the five items of the Positive and Negative Syndrome Scale-Excited Component (PANSS-EC) using the 1-7 scoring system prior to the first injection of study drug.
  • Patients have a score of 1 or 2 on the Agitation-Calmness Evaluation Scale (ACES) prior to the first injection of study drug.

Exclusion Criteria:

  • Patients who have a known neutrophil count or total of segmented cell and band cell counts of <1,500 /millimeter cubed (mm3).
  • Patients who have a known alanine aminotransferase/serum glutamic pyruvic transaminase (ALT/SGPT) values ≧2 times the normal upper limit of the performing laboratory (ULN) or aspartate aminotransferase/serum glutamic oxaloacetic transaminase (AST/SGOT) values ≧3 times the ULN or total bilirubin values ≧1.5 times the ULN.
  • Patients who have a known serum triglycerides ≧500 milligrams/deciliter (mg/dL).
  • Electrocardiogram abnormalities considered clinically significant by the investigator.
  • Patients who have had treatment with injectable depot antipsychotics within one injection interval prior to study drug administration.
  • Patients who have received treatment with antipsychotics or other prohibited concomitant medicines showing in the section "prohibited concomitant medicines" within 2 hours prior to the first IM study drug administration.
  • Patients who have had treatment with benzodiazepines within 4 hours prior to first IM study drug administration.
  • Patients who have been administered epinephrine within 24 hours prior to the first IM study drug administration.
  • Patients who have received treatment with psychostimulants or reserpine within 7 days prior to the first IM study drug administration.
  • Patients who have received beta blockers or calcium channel blockers previously, must have been taking the same medication at the same dose for 28 days prior to the first IM study drug administration. No beta blockers or calcium channel blockers may be administered within 24 hours of the first IM study drug injection, or any time during the double blind phase.

Expérimental: IM olanzapine 10mg
Patients will receive at least one injection of Intramuscular (IM) 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).
Médicament: Rapid Acting Intramuscular Olanzapine
10mg/injection, IM. If patients do not respond to the first 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).
Autres noms:

  • LY170053
  • RAIM
Comparateur placebo: 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).
Médicament: Isotonic sodium chloride solution
0.9% sodium chloride (NaCl) solution. If patients do not respond to the first 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).

Description de la mesure
Délai
Change From Baseline to 2 Hours Post the First Intramuscular (IM) Injection in Positive and Negative Syndrome Scale-Excited Component (PANSS-EC)
Délai: 2 hours post first intramuscular (IM) injection
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.

Délai: 15 min, 30 min, 60 min, 90 min post first IM injection
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.

Number of Participants With Scores of 4 to 7 in the Agitation-Calmness Evaluation Scale (ACES) at Each Timepoint
Délai: 30 min, 60 min, 90 min and 2 hours post first IM injection
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.
30 min, 60 min, 90 min and 2 hours post first IM injection
