Summary

The purpose of this study is to examine the safety and effectiveness of the long acting injectable form of the atypical antipsychotic Risperidone (Risperdal CONSTA), along with treatment as usual (TAU), in bipolar disorder patients who had more than 4 mood episodes in the past year.

Clinical Details

Official title: A Prospective, Randomized, Double-blind, Placebo-controlled Study of the Effectiveness and Safety of RISPERDAL CONSTA Augmentation in Adult Patients With Frequently-relapsing Bipolar Disorder

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Efficacy will be determined by measuring the time (in days) from randomization to event/relapse; relapse will be assessed by clinical status, rating scale changes, and pharmacologic stability in double-blind phase.

Secondary outcome: Safety and tolerability as assessed by adverse event reports (every 2 weeks), scores on movement disorder measures, laboratory parameters, vital signs, ECG measures and physical examination reports (every 2-3 months)

Detailed description: Frequently-relapsing (more than 4 episodes in the last year) bipolar patients are a sub-group of patients who have multiple mood episodes in spite of treatment. Currently available treatments may have little impact on number and frequency of manic and/or depressed mood episodes and as a result, these patients have higher than average rates of illness and death. This study examines the effectiveness and side effects of risperidone long-acting injections (LAI) added to treatment as usual (TAU) in frequently-relapsing bipolar patients. The study has two main phases. The first phase is open-label (patients and doctors know what medication and dose the patient is receiving- both risperidone LAI and TAU) and lasts 16 weeks. During that time, patients are treated with the goal that they reach "remission", a predefined level of improvement (decrease in number and severity of mood episodes.) Patients who meet remission criteria at the end of the first phase are randomized (like flipping a coin) to either continue receiving the same dose of risperidone LAI plus TAU, or placebo injections plus TAU. Patients continue in the second phase for 52 weeks, during which time the effectiveness is measured by time to "relapse" (worsening of mood symptoms severe enough to require hospitalization or a major change in medication.) Additional effectiveness, safety, and side effect measures are evaluated throughout the length of the study. Long-acting risperidone injection 25 mg will be administered every two weeks through a gluteal injection for at least one month. Thereafter, the dose may be increased to 37. 5mg then to 50 mg based on clinical response and tolerability. Supplemental use of oral Risperdal (1 to 2 mg/day) will be permitted during the first 12 weeks of the Open-Label Stabilization Phase. Patients must be taking a stable dose of risperidone LAI for the 4 weeks immediately prior to entering the Double-Blind Phase.

Eligibility

Minimum age: 18 Years. Maximum age: 70 Years. Gender(s): Both.

Criteria:

Inclusion Criteria:

- Must provide informed consent

- Must agree to receive regular injections

- Must have current diagnosis of bipolar disorder I or II

- Must have at least four episodes of mood disorder in the last year that required

psychiatric intervention Exclusion Criteria:

- Female who is or may be pregnant or breastfeeding, who is not at least 1 year

postmenopausal, or is not using reliable and adequate birth control

- Psychiatric diagnosis is due directly to effects of a substance or general medical

condition

- Substance dependence

- Received treatment with a long-acting injectable antipsychotic less than 2 injection

cycles prior to baseline (so, for example, if the drug is injected every 2 weeks, the patient could not enroll in the study if they had received an injection within the last 4 weeks)

- Received Electroconvulsive Therapy (ECT) within the last month

- Began psychotherapy ("talk therapy") within 2 months

- In the past month was treated with any of these medications: carbamazepine,
