Open-Label Study of Intramuscular Olanzapine Depot in Patients With Schizophrenia or Schizoaffective Disorder

Eli Lilly and Company931 enrolled

Overview

This is a long-term, open-label clinical study designed to enable longer-term treatment of patients completing other clinical studies with intramuscular olanzapine depot. Key objectives of the study are to: * Determine how well intramuscular (IM) olanzapine depot works during long-term treatment, * Evaluate the safety and tolerability of IM olanzapine depot during long-term treatment, * Determine the blood levels of IM olanzapine depot in patients during long-term treatment

Extrapyramidal symptoms are defined as Simpson-Angus total score (SAS) \>3 at any post-baseline visit; Barnes Akathisia Scale (BAS) global score ≥2 at any post-baseline visit; A score ≥3 for any of Abnormal Involuntary Movement Scale (AIMS) for items 1-7 or a score ≥2 for any two of these items. Score for SAS is 0-4 for each of the 10 questions, with 0=normal and 4=extreme. The possible total score for SAS is 0-40. Possible score for BAS is 0-5, with 0=absent and 5=sever. Score 0-4 for each item of AIMS, with 0 =none and 4= sever. Possible total score for items 1-7 is 0-28.

Time frame: Randomization to end of study up to 76 months

Secondary Outcomes

Change From Baseline in Positive and Negative Syndrome Scale (PANSS) Total Scores at Month 76 Endpoint

Assesses the positive symptoms, negative symptoms, and general psychopathology specifically associated with schizophrenia. The scale consists of 30 items. Each item is rated on a scale from 1 (symptom not present) to 7 (symptoms extremely severe). The sum of the 30 items is defined as the PANSS total score and ranges from 30 to 210.

Time frame: Baseline, up to 76 months

Change From Baseline in PANSS Positive Scores at Month 76 Endpoint

PANSS questions 1-7. Assesses positive symptoms associated with schizophrenia. 7 items make up the positive scale (ex. delusions, conceptual disorganization, and hallucinatory behavior). Each item is rated on a scale from 1 (symptom not present) to 7 (symptoms extremely severe). Total positive subscale scores range from 7 to 49.

Time frame: Baseline, up to 76 months

Change From Baseline in PANSS Negative Scores at Month 76 Endpoint

PANSS questions 8-14. Assesses negative symptoms associated with schizophrenia. 7 items make up the negative scale (e.g. blunted affect, emotional withdrawal, poor rapport, and passive/apathetic social withdrawal).

Change From Baseline in the Heinrichs-Carpenter Quality of Life Scale (QLS) Total Score at Month 76 Endpoint

Heinrich-Carpenter QLS is an interviewer-rated scale which measures the impact of negative symptoms on occupational, social, and psychological functioning in patients with schizophrenia or schizoaffective disorder. Each of 21 items is rated on a scale from 0 (severely impaired functioning) to 6 (normal or adequate functioning), for a total score range of 0-126. Results are presented as change in Total score.

Each domain is scored by summing the individual items and transforming the scores into a 0 to 100 scale, with higher scores indicating better health status or functioning. The mental component summary (MCS) and the physical component summary (PCS) have been constructed based on the 8 SF-36 domains.
