A Study of the Effectiveness and Safety of Risperidone in the Treatment of Behavioral Disturbances in Patients With Dementia

November 18, 2010 updated by: Janssen-Cilag Pty Ltd

Risperidone in the Treatment of Behavioural and Psychological Signs and Symptoms in Dementia (BPSSD): a Multicentre, Double-blind, Placebo-controlled Parallel-group Trial

The purpose of the study is to compare the effectiveness of an oral formulation of risperidone (an antipsychotic medication) to that of placebo for treating behavioral and psychological signs and symptoms in dementia (BPSSD), specifically aggression, delusions, and hallucinations, in patients with dementia.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Detailed Description

Dementia is a term used for a collection of symptoms that can be caused by a number of diseases or injuries that affect the brain. Individuals with dementia have a loss of function in cognition (thinking, perception, learning, verbal communication, memory, judgment), which may lead to behavioral and personality changes (for example, agitation, delusions, hallucinations). Some causes of dementia are reversible; however, irreversible dementia is caused by certain conditions, such as Alzheimer's disease. Dementia is common in elderly individuals, but it is not a normal part of aging. This is a randomized, double-blind, parallel-group, placebo-controlled study comparing the effectiveness and safety of risperidone to placebo in patients with behavioral disturbances associated with dementia. The study is composed of two periods: a 1-week run-in period in which patients are discontinued from other antipsychotic drugs and take placebo twice daily and a 12-week double-blind period. At the end of the run-in period, patients are randomly assigned to oral solutions of either risperidone or placebo. The starting dose of risperidone is 0.25 mg twice daily and increasing to 0.5 mg twice daily (1 mg/day). If 1 mg/day shows an insufficient response, a maximum of 1 mg twice daily of risperidone is permitted. The patient receives study drugs for the 12-week double-blind period. The primary measure of effectiveness is the change from baseline to the end of double-blind treatment in the Cohen-Mansfield Agitation Inventory (CMAI), a questionnaire evaluating agitation. Additional measures of efficacy include the change from baseline to end of double-blind treatment in the Behavior Pathology in Alzheimer's Disease Rating Scale (BEHAVE-AD), a rating scale used to evaluate behavior symptoms in patients with Alzheimer's disease; the Clinical Global Impressions (CGI), a rating system used to evaluate the overall and severity of clinical change in a patient with various diseases affecting the brain; the Functional Assessment Staging (FAST), a diagnosis tool for determining the stage of dementia; and the Mini-Mental State Examination (MMSE), a clinical measure used to evaluate cognition. Safety evaluations include the incidence of adverse events; results of clinical laboratory tests (hematology and biochemistry); measurements of vital signs and body weight; physical examination findings; and the Extrapyramidal Symptoms Rating Scale (ESRS), a scale used to measure effects of antipsychotic medications on motor functions of the patient. The study hypothesis is that risperidone is more effective than placebo, as measured by the total aggression score on the CMAI, in treating behavioral disturbances in demented patients. Risperidone oral solution (1 mg/mL). Starting doses of 0.25 mg twice daily and increasing to 0.5 mg twice daily (1 mg/day). If 1 mg/day shows an insufficient response, a maximum of 1 mg twice daily of risperidone is permitted. Total treatment duration is 12 weeks.

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
344

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

55 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Dementia of the Alzheimer's type with behavioral disturbance, vascular dementia with behavioral disturbance, or mixed dementia, as classified by DSM-IV (the Diagnostic and Statistical Manual of Mental Diseases, 4th edition)
  • a score >=4 on the FAST (Functional Assessment Staging, a diagnosis tool for determining the stage of dementia) and a score <=23 on the MMSE (Mini-Mental State Examination, a clinical measure used to evaluate cognition)
  • a BEHAVE-AD (Behavior Pathology in Alzheimer's Disease Rating Scale) total score >=8, and a BEHAVE-AD global rating >=1
  • patient must be living in an nursing home for >=1 month. Exclusion Criteria:
  • Patients with other medical or neurological conditions other than dementia in which cognition is diminished (for example, severe anemia, severe liver, heart, lung, and kidney malfunctions, Parkinson's disease)
  • diagnosis of depression within the 6 months before study entry, schizophrenia, bipolar affective disorder, or schizoaffective disorder
  • history of or moderate to severe tardive dyskinesia, (a condition of uncontrollable movements of the tongue, lips, face, trunk, hands and feet that is seen in patients receiving long-term medication with certain types of antipsychotic drugs)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Change from baseline to the end of double-blind treatment in total aggression score of the CMAI (Cohen-Mansfield Agitation Inventory).

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Change from baseline to end of double-blind treatment in global and total BEHAVE-AD score, BEHAVE-AD cluster scores and in CMAI cluster scores, CGI, and in FAST MMSE; safety evaluations conducted throughout the study.
