About this study
Official title: Efficacy And Safety Of A Flexible Dose Of Risperidone Versus Placebo In The Treatment Of Psychosis Of Alzheimer's Disease.
The purpose of this study is to evaluate the efficacy and safety of risperidone compared with placebo in the treatment of psychotic symptoms in patients with Alzheimer's disease
Read the detailed description
Dementia is frequently observed in the elderly, often associated with psychotic symptoms such as delusion or hallucinations, or with behavioral disturbances such as aggressive behavior, wandering, and aimless behavior induced by the psychotic symptoms. This is a double-blind, placebo-controlled study of the effectiveness and safety of risperidone (taken twice daily over 8 weeks) in the treatment of psychotic symptoms in patients with Alzheimer's disease. Assessments of effectiveness include: Behavioral Pathology in Alzheimer's Disease (BEHAVE-AD), a scale used for global assessment of symptoms associated with dementia; the Psychosis Cluster Scale of BEHAVE-AD, a subscale that assesses paranoid and delusional ideation as well as hallucination; and Clinical Global Impression-Change (CGI-C), a measure of an improved or aggravated condition. Safety evaluations include the incidence of adverse events throughout the study; physical examinations, electrocardiograms (ECGs), laboratory tests (hematology, biochemistry, urinalysis), and assessment of extrapyramidal symptoms at specified intervals. The study hypothesis is that treatment with risperidone shows greater improvement in psychotic symptoms, as measured by the BEHAVE-AD psychotic cluster score, in patients with Alzheimer's disease, as compared to placebo. In addition, it is hypothesized that risperidone is well tolerated. Risperidone tablets (0.25 mg or 0.50 mg) or placebo tablets taken orally twice daily. Total daily dosage of 0.5mg on Day 1, 1.0mg on Days 3-5, and 1.5mg (maximum dose) on Days 5-13. Optimum dose maintained during Weeks 3-8 of treatment.Dose may be increased or decreased at investigator's discretion.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing risperidone in people with Dementia and Alzheimer Disease, run by Johnson & Johnson Pharmaceutical Research & Development, L.L.C..
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 1 Feb 2011. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change from baseline to end of treatment (Week 8) in Psychosis Cluster Score of Pathology from the Behavioral Pathology in Alzheimer's Disease (BEHAVE-AD) Rating Scale and Clinical Global Impression (CGI).. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00034762, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Feb 2011.
