About this study

Official title: Neuroleptic Induced Movement Disorders in Older Patients

This study will assess the risk of experiencing tardive dyskinesia and other movement disturbances associated with three atypical antipsychotic drugs among middle-aged and elderly psychiatric patients.

Read the detailed description

Use of antipsychotic drugs can result in tardive dyskinesia and extrapyramidal symptoms. Tardive dyskinesia (TD) is a syndrome that causes repetitive, involuntary, purposeless movements in the tongue, lips, or jaw. It can also cause facial grimacing, random movements of arms, legs, fingers, and toes, as well as swaying movements of the trunk or hips. Extrapyramidal symptoms (EPS) include a variety of symptoms, such as involuntary movements, tremors, rigidity, body restlessness, and changes in breathing and heart rate. TD and EPS are side effects of older antipsychotic drugs. Newer antipsychotic drugs, such as quetiapine, olanzapine, and risperidone, do not present as large a risk of developing these side effects. This study will assess the incidence of and risk factors for tardive dyskinesia and extrapyramidal symptoms associated with quetiapine, olanzapine, and risperidone among middle-aged and elderly individuals with psychotic disorders. Additionally, the study will examine the effect of these drugs on symptoms of pre-existing, drug-induced TD. It will also explore the impact of movement disorder symptoms on everyday functioning and quality of life.

Some participants in this open-label study will be randomly assigned to receive quetiapine, olanzapine, or risperidone. Participants who are not randomly assigned to a medication will still receive one of the three medications, based on the decision of their physician. Initial evaluations will be conducted to collect demographic information, as well as medical, psychiatric, and pharmacologic histories. Dosing will be determined by each participant's psychiatrist. All participants will be followed for approximately 5 years. They will report to the study site for outcome assessments at baseline, Months 1 and 3, and every 3 months for the remainder of the study.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Quetiapine, Risperidone and Olanzapine in people with Dyskinesia, Drug-Induced, run by University of California, San Diego at 1 site in United States.

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 1 inclusion and 1 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 6 Jun 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Extrapyramidal symptoms; measured at Months 1 and 3 and every 3 months for the remainder of the study. The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 6 Jun 2013.
