Efficacy and Safety of Olanzapine in Patients With Borderline Personality Disorder: A Randomized Double-Blind Comparison With Placebo

To assess the efficacy of olanzapine therapy (5.0-10.0 mg/day) compared with placebo in patients with BPD,as defined by DSM-IV-TR criteria,

in improving overall symptomatology as measured by the last observation carried forward (LOCF) mean change from baseline to endpoint in the ZAN-BPD total score for up to 12 weeks of double-blind treatment.

To assess the efficacy of olanzapine 2.5 mg/day compared with placebo in patients with BPD, as defined by DSM-IV-TR criteria

in improving overall symptomatology as measured by last observation carried forward (LOCF) mean change from baseline to endpoint in the ZAN-BPD total score for up to 12 weeks of double-blind treatment

to evaluate the level of functioning as measured by LOCF mean change from baseline to endpoint on the Sheehan Disability Scale (Work, Social Life,and Family Life/Home Responsibilities)total score

and individual scores(Work, Social Life,Family Life/Home Responsibilities, Days Lost, and Days Under Productive)

to assess the reduction of aggression, suicidality, and irritability as measured by the LOCF mean change from baseline to endpoint in the rating of the Overt Aggression Scale-Modified (OAS-M) total score

to assess the reduction of self-mutilation determined by the mean frequency of self-mutilation attempts as captured on the Lifetime Self-Destructiveness scale (LSDS), which will measure both frequency and nature of attempts

The frequency of self-mutilation for each patient will be calculated as the number of self-mutilations divided by the patient's total number of study drug exposure

(Self-mutilation is defined as deliberate physical self harm without the intent to commit suicide)

to assess the reduction of suicide attempts as determined by the mean frequency of suicide attempts.

The frequency of suicide attempts for each patient will be calculated as the number of suicide attempts divided by the patient's total number of days of study drug exposure

to assess the treatment of the core domains of BPD as assessed by LOCF mean change from baseline to endpoint in each of the four ZAN-BPD domain scores (cognitive disturbances,disturbed relationships,affective disturbances,and impulsivity)

to assess the following symptom domains (paranoid ideation, psychoticism, anxiety, depression, anger/hostility, interpersonal sensitivity, phobic anxiety, obsessive-compulsive, and somatization)on the Global Severity Index of the SCL-90-R

as determined by the LOCF mean change from baseline to endpoint

to evaluate the rate of response, time in response, and time to response. Levels of response are defined as a 30% and 50% reduction in the ZAN-BPD total score from baseline (Visit 2)

to assess the treatment of depressive mood symptoms as measured by LOCF mean change from baseline to endpoint in the total score on the Montgomery-Asberg Depression Rating Scale (MADRS)

to assess the resource utilization by frequency divided by the patient's total number of days of study drug exposure for days hospitalized for physical and psychological reasons,number of hospital admissions

or medical visits(emergency department, general and special care physicians, and other mental health care professionals

to evaluate the level of functioning in patients as measured by LOCF mean change from baseline to endpoint on the GAF

to assess the safety as measured by treatment-emergency adverse events (TEAE), change in vital signs and laboratory analytes, electrocardiograms and severity of any extrapyramidal symptoms (EPS)

The Simpson Angus Scale, Abnormal Involuntary Movement Scale and Barnes Akathisia Scale will be used to measure EPS

The objectives of Study Period III (Open Label Extension Period are:

to assess the longer term safety of olanzapine for up to 12 additional weeks of therapy

as measured by TEAE, change in vital signs and laboratory analytes, ECG and severity of EPS.

to explore the efficacy of continued olanzapine treatment for up to 12 additional weeks of therapy

as measured by the ZAN-BPD total score, MADRS, Sheehan Disability Scale and LSDS

to assess resource utilization by frequency of divided by the patient's total number of days of study drug exposure for

days hospitalized for physical and psychological reasons, number of hospital admissions

or medical visits (emergency department, general and special care physicians or other mental health care professionals
