Quetiapine Treatment for Symptoms Associated With Borderline Personality Disorder

Quetiapine Treatment for Symptoms Associated With Borderline Personality Disorder

Objective:

The objective of this study is to quantitatively examine the efficacy of Seroquel (active ingredient quetiapine fumarate) in subjects with Borderline Personality Disorder (BPD). A secondary objective is to characterize the safety and tolerability of utilizing quetiapine in patients with Borderline Personality Disorder.

Design:

Investigator initiated, 6-week, non-placebo controlled, non-randomized, open-label, single drug, single-center, medication trial.

Participants:

Volunteers (n = 15) diagnosed with Borderline Personality Disorder using the Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II).

Interventions:

Subjects with Borderline Personality Disorder are washed out of all other medications. The subjects are then given the study drug at a dose within the drug's known therapeutic range.

Study Design: A six week, open-label, flexible dosing study using quetiapine. Subjects who qualify at Screening will then proceed to the baseline visit. If all inclusion and exclusion criteria are met, subjects will be administered quetiapine at the baseline visit. Enrollment will be 15 subjects. Enrollment is expected to last for a 6 month period.

8. Subjects who have abnormal laboratory results will be discontinued from the study.

Visit 1 (Baseline).

Review of the following:

• Lab work
• Adverse Events
• Concomitant Medications
• Inclusion and Exclusion Criteria
• Beck Anxiety Inventory (BAI)
• Beck Depression Inventory ( BDI-II)
• Buss-Durkee Hostility Inventory (BDHI)
• Global Assessment of Functioning (GAF)
• Symptom Checklist 90 (SCL-90-R)
• Clinical Global Impression Scale (CGI) for severity of illness (Global Improvement and Efficacy not rated)
• Abnormal Involuntary Movement Scale (AIMS)
• Simpson-Angus Scale

Study Medication:

The investigator completes all evaluations and determines the medication dosage.

The study coordinator will then dispense the appropriate number of quetiapine tablets.

Visit 2 (Week 1); Visit 3 (Week 2); Visit 4 (Week 3); Visit 5 (Week 4); Visit 6 (Week 5).

Scales that will be used to assess positive change and medication safety during these visits are:

Scales (in alphabetical order):

• Abnormal Involuntary Movement Scale (AIMS)
• Beck Anxiety Inventory
• Beck Depression Inventory
• Buss-Durkee Hostility Inventory (BDHI)
• Clinical Global Impression (CGI)
• Global Assessment of Functioning GAF
• Simpson-Angus Scale

Inclusion Criteria:

To be considered for inclusion in this study subject must:

• Provide written informed consent before beginning any study related activities
• Be between age 18 and 55 years
• Be able to speak, read and write English and follow simple instructions for completing self-rated scales
• Meet DSM-IV criteria for BPD as assessed by the Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II). Those items screened positive by the subject on the Personality questionnaire will be further evaluated by pertinent subsections of the SKID-II.

Concomitant Therapy

Antipsychotic agents other than quetiapine will not be allowed during the study period. Patients who are taking other antipsychotic medication will require at least a three day washout period prior to the baseline visit.

Patients on anticonvulsants, lithium and benzodiazepines will be allowed to enter the study if they have been on the same dose of these agents for three months prior to the baseline visit

How Will the Study Be Analyzed

Laboratory Studies: Studies will be done at baseline and will screen for liver disease, kidney disease, electrolyte imbalance, thyroid or parathyroid dysfunction, respiratory acidosis or alkalosis, anemia, adequate blood cell and platelet count, pregnancy, and presence of illegal drugs. Any subjects with significant laboratory abnormalities will be excluded from the study.

Adverse Events: Subjects will be screened for the following side effects of quetiapine which are dizziness (10%), postural hypotension (7%), dry mouth (7%), and dyspepsia (6%), tachycardia (7%) and somnolence (18%). Patients will be also be monitored for other rare events including seizures, tardive dyskinesia, and neuroleptic malignant syndrome (NMS). Other less common side effects (> 1%) include headache (19% vs placebo 17%), asthenia (3% vs 2%), abdominal pain (3% vs 1%), back pain (2% vs 1%), fever (2% vs 1%), constipation (9% vs 5%),w eight gain (2% vs 0%), rash (4% vs 3%), rhinitis (3% vs 1%), and ear pain (1% vs 0%).

Data Analysis

The following will be reported and statistically analyzed:

• Number of patients who begin and complete the study (maximum n = 15).
• Patients who dropout of the study or are terminated with reasons.
• Demographic characteristics of the patients.
• Number of patients who had personality disorders in addition to Borderline Personality Disorder.
• The final average dose of quetiapine.
• The total score and percentage change of each scale and subscale utilized in the study and whether there was a statistically significant increase or reduction during the period of quetiapine administration.
• Movement Disorder side effects as assessed by the Abnormal Involuntary Movement Scale and the Simpson-Angus Scale and whether there was a statistically significant increase or reduction during the period of quetiapine administration.
• The number and percentage of adverse events that occurred during the period of quetiapine administration.
• The number and percentage of any abnormal laboratory results that occurred during the period of quetiapine administration.

After completion of data collection, the data will be analyzed to determine appropriate parametric analyses. As the N for this study will be 15, a T-test analysis may be applicable if the data permit. We anticipate a preliminary demonstration of treatment effect. Individual weekly scores will serve as dependent variables which lend themselves to a one-way analysis to demonstrate difference between baseline and 6 weeks of active treatment. If our data permit, a two-way T-test will also be employed to demonstrate statistically significant differences in treatment effect. As our data will likely require the utilization of multiple two-way analyses, our data will be Bonferroni corrected in order to adjust for the possibility of false positive (type II) errors. Other parametric analyses will be employed as the data warrant.
