About this study

Official title: The Effect of Melatonin Treatment on Tardive Dyskinesia and Oxidative Stress: A Double-Blind Placebo-Controlled Trial

This is a double-blind, randomized, placebo-controlled trial of melatonin as an add-on therapy to antipsychotics will be performed to examine the effects of melatonin on tardive dyskinesia symptoms and cognitive deficits in 120 patients with established tardive dyskinesia (TD). This study addresses a free radical hypothesis of TD.

Read the detailed description
  1. Since it has been proposed that neuroleptic-induced increases in free-radical production may relate to the development of TD, the investigators hypothesize that melatonin, an effective antioxidant, may attenuate the severity of tardive dyskinesia symptoms.
  2. Due to increased cognitive deficits in patients with TD and implication of oxidative stress in cognitive impairment, the investigators hypothesize that both cognitive impairment and tardive dyskinesia symptoms may be induced by the same pathophysiological stimulus--oxidative stress. Hence, the investigators further hypothesize that both tardive dyskinesia symptoms and cognitive deficits in patients with TD may be improved by melatonin simultaneously.

Questions about this trial

What is this clinical trial studying?

A study testing Melatonin in people with Tardive Dyskinesia, run by Beijing HuiLongGuan Hospital at 1 site in China.

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 4 inclusion and 6 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 12 Jul 2016. 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 China. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

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?

the Abnormal Involuntary Movement Scale (AIMS) (time frame: 12 weeks). 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 12 Jul 2016.
