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

The list of serious adverse events (SAE) and other non-serious adverse events (AE) are in Adverse Events Section.

Prolactin normal reference ranges for female: 2.0 - 29.0 nanograms per milliliter (ng/mL); male: 2.0 - 20.0 ng/mL. High value is defined as a change from a value less than or equal to the high limit at all baseline visits to a value greater than the high limit at any time after baseline.

High ALT is defined as a baseline value of <3 times the upper limit of normal (ULN) to ≥3 times the ULN at any time post baseline. High AST is defined as a baseline value of <5 times the ULN to ≥5 times the ULN at any time post baseline. High total bilirubin is defined as a baseline value of <2 times the ULN to ≥2 times the ULN at any time post baseline.

Normal to high fasting glucose ≤100 milligrams per deciliter (mg/dL) at baseline to ≥126 mg/dL any time post baseline.

Normal to high fasting total cholesterol ≤200 mg/dL at baseline to ≥240 mg/dL any time post baseline. Fasting triglycerides <150 mg/dL at baseline to ≥200 mg/dL and <500 mg/dL any time post baseline.

Mean change in weight from baseline to last observation carried forward (LOCF) endpoint.

PCS weight gain is defined as a ≥7% increase in weight from baseline.

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.

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.

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.

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). Each item is rated on a scale from 1 (symptom not present) to 7 (symptoms extremely severe). Total negative subscale scores range from 7 to 49.

PANSS General Psychopathology Subscale is the Remaining 16 PANSS questions or PANSS Question15 through Question 30. Each item is rated on a scale from 1 (symptom not present) to 7 (symptoms extremely severe). The sum of the 16 items is defined as the PANSS General Psychopathology Subscales. Possible score ranges from 16 to 112.

Measures severity of illness at the time of assessment compared with start of treatment. Scores range from 1 (normal, not at all ill) to 7 (among the most extremely ill patients).

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.

A self-reported questionnaire that consists of 36 questions covering 8 health domains (physical functioning, social functioning, bodily pain, vitality, mental health, role-physical, role-emotional and general health). 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.

Psychiatric visits were outpatient visits to a psychiatrist or psychiatric nurse.

This is the total number of days for all hospitalized patients that were admitted to General, Psychiatric Ward as well as Intensive Care Unit (ICU).

The Subjective Well-Being under Neuroleptic Treatment-Short Form (SWN-S) is a patient self-rated scale developed to measure the subjective well-being for the previous 7 days of a patient under neuroleptic treatment. The SWN-S consists of 20 items (each item is rated from 1=not at all to 6=very much). Possible total score ranges from 20-120.

Self-rated scale that measures patient's level of satisfaction with current antipsychotic medication. Consists of 3 items assessing satisfaction with current study medication (scored from 1='very dissatisfied' to 5='very satisfied'), preference comparing current study medication versus previous medications (scored from 1='much prefer previous medication' to 5='much prefer study medication'), and side effects of current study medication compared with previous medications (scored from 1='much less side effects' to 5='much more side effects'). Range of possible scores is 3-15.

Plasma olanzapine concentrations are expressed as (nanogram/milliliter)/(milligram/day) ([ng/mL]/[mg/day]).
