  Purpose

The purpose of this research study is to evaluate the safety, tolerability, and efficacy (how well the drug works) of risperidone compared to placebo (an inactive drug) in the treatment of bipolar disorder with panic disorder or generalized anxiety disorder. Risperidone is currently approved by the United States Food and Drug Administration (FDA) for the treatment of schizophrenia and bipolar mania. Risperidone is not currently FDA approved for the treatment of bipolar hypomania with or without panic disorder or generalized anxiety disorder (the condition being investigated in this study).

  Hide Detailed Description

Detailed Description:

Methods and Procedures:

This is a randomized, double-blind, placebo controlled, parallel-group, 3 site, 8-week trial of risperidone monotherapy in outpatient subjects with a lifetime bipolar I, II, or not otherwise specified (NOS) disorder, a lifetime panic or generalized anxiety disorder, and current, at least moderately, severe anxiety symptoms. Approximately 90 subjects will be enrolled to obtain 60 subjects who complete the 8-week trial. Subjects will be randomized to risperidone or placebo in a 1:1 ratio. No concomitant psychotropic medication will be allowed except for as needed (prn) lorazepam during the first two weeks for the management of affective and anxiety symptoms, and prn zolpidem and zaleplon throughout the study for the management of insomnia. Throughout the study, psychiatric scales will be used to assess psychiatric symptoms and the presence of treatment-emergent adverse events will be monitored and recorded.

Medication Dosing:

Risperidone will be administered at an initial dose of 0.5 to 1 mg/day and will be titrated upward to a dose considered optimal by the investigator based on the subject's clinical response and adverse events, but not to exceed 2.0 mg/day by the end of the second week. Subsequently, risperidone may be increased based on clinical response and tolerability to a maximum of 4.0 mg/day. As needed study-prescribed (prn) use of lorazepam will be allowed for the management of affective and anxiety symptoms for the first two weeks of the study; a maximum of 2 mg per day will be allowed during the first week, and a maximum of 1 mg per day will be allowed during the second week. During the second week, the subject must be tapered off the lorazepam. For the final six weeks of the study, no lorazepam will be permitted. Zolpidem (10-20 mg/day) or zaleplon (10-20 mg/day) will be allowed for management of insomnia, and benztropine (0.5 - 3.0 mg/day) will be allowed for management of extrapyramidal symptoms. The latter three agents will be permitted throughout the study.

From week 2 on, any medications with psychotropic effects are prohibited.

Screening Visit(s):

The Screening Period will last a minimum of 2 to a maximum of 30 days. At the first screening visit (Visit 0), informed consent will be obtained. The Mini International Neuropsychiatric Interview (MINI), with the Manic Module from the MINI plus, will be performed to establish whether the patient meets DSM-IV criteria for bipolar disorder I, II, or NOS, and for panic disorder or generalized anxiety disorder. For generalized anxiety disorder, the portion of Criterion F - that stipulates "the disturbance does not occur exclusively during a mood disorder" will be suspended. The CGI-BP and the CGI-S will be performed to establish the severity of bipolar affective symptoms and anxiety symptoms, respectively. Subjects will keep a mood chart in between visits to help them follow their affective and anxiety symptoms. The subject's bipolar symptoms must be evaluated as no more than moderately severe (defined as a CGI-BP < 4), and his/her anxiety symptoms must be evaluated as at least moderately severe (a CGI-S of > 4) for him/her to be able to continue in the screening process and enter the randomized phase. Medical history will be reviewed, a physical exam performed, electrocardiogram (EKG) and laboratory studies (complete metabolic profile, CBC with differential and platelets, urinalysis, pregnancy test, and urine drug screen) will be obtained. Based on these evaluations, it will be determined whether subjects meet entry criteria; subjects meeting these criteria will continue in the screening process.

Baseline Visit (last Screening Visit):

At baseline (Visit 1), subjects whose screening evaluations continue to meet all inclusion/exclusion criteria may enter the study and be randomized. These evaluations will include repeating the Clinical Global Impression modified for bipolar illness (CGI-BP) and the Clinical Global Improvement Scale for anxiety symptoms (CGI-S) to ensure the subject continues to have no more than moderately severe bipolar affective symptoms and at least moderately severe anxiety symptoms. Baseline ratings will include: the Sheehan Panic Anxiety Scale-Clinician Rated (SPAS-C); the Hamilton Anxiety Scale (HAM-A) to assess anxiety symptoms; the Young Mania Rating Scale (YMRS) to assess manic symptoms; and the Inventory for Depressive Symptoms (IDS) (long form) to assess depressive symptoms. Subjects will also be evaluated with the CGI-BP, and the Sheehan Disability Scale (SDS). The Panic-Agoraphobic Spectrum-Self-Report (PAS-SR) will be used to assess the lifetime presence of core and related features of panic disorder. (Subjects who score > 35 on the PAS-SR will be classified a-priori as having panic spectrum symptoms [PSS]). The Family Impact Scale (FIS) will be administered. The Abnormal Involuntary Movement Scale (AIMS), Simpson Angus Scale (SAS), and Barnes Akathisia Rating Scale (BARS) will be administered to assess for extrapyramidal symptoms. Blood pressure, pulse, height, and weight, will be measured. Study medication will be dispensed by the Physician Investigator in the form of 0.5 mg capsules. The dose range of risperidone will be 0.5 to 4 mg/day.

Treatment Period:

Study visits will occur every week through the eight weeks of treatment. It is expected that risperidone will be gradually increased to an optimal dose during the first month of treatment. The following procedures will be completed at each visit.

  1. Collect unused risperidone, perform study drug accountability, and record dosage of study drug used. A subject's unused study medication can be re-dispensed back to the subject.
  2. Review mood chart and administer Clinician Global Improvement on anxiety symptoms -21 point scale (CGI-I-21), Patient Global Improvement on anxiety symptoms -21 point scale (PGI-21), SPAS-C, HAM-A, YMRS, IDS, CGI-BP, and SDS ratings.
  3. Assess and record adverse events.
  4. Perform AIMS, SAS, and BARS.
  5. Obtain blood pressure, pulse, and weight.
  6. Record concomitant medication use (from mood chart)
  7. Adjust risperidone dose (if necessary) and dispense study drug.

Final Evaluation (week 8) or Early Termination:

The following evaluations will be conducted at the completion of, or early withdrawal from, the 8-week treatment phase. All psychiatric evaluations and all other final study procedures (including a repeat physical exam, EKG, and laboratory studies) will be completed prior to the discontinuation of risperidone. The evaluations to be performed are:

  • Collect unused risperidone, perform study drug accountability, and record dosage of study drug used.
  • Review mood chart and perform CGI-21, SPAS-C, HAM-A, YMRS, IDS, CGI-BP, PGI-21, and SDS ratings.
  • Repeat PAS-SR
  • Repeat FIS
  • Assess and record adverse events.
  • Obtain blood pressure, pulse, weight, and determine BMI.
  • Perform physical examination, AIMS, SAS, BARS.
  • Obtain laboratories (complete metabolic profile, CBC with/differential and platelets, urinalysis, pregnancy test, and urine drug screen).
  • Repeat EKG.
  • Record concomitant medication use (from mood chart)
  • Adjust risperidone dose (if necessary) and prescribe drug (if subject has responded and chooses to continue on risperidone), or dispense risperidone taper for discontinuation (if subject has not responded or if subject chooses to discontinue risperidone for any reason).
