What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether a non-invasive brain stimulation method called rTMS can reduce the involuntary muscle spasms caused by long-term use of certain psychiatric medications. Researchers will use MRI scans to precisely target the stimulation in 62 adults with tardive dyskinesia. Half will receive real rTMS and half a sham treatment, and their movement symptoms will be measured after 14 days.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
repetitive transcranial magnetic stimulation (rTMS)
What this could lead to
If it works, this could provide a non-invasive, drug-free option to reduce uncontrollable movements in people with tardive dyskinesia.
What could go wrong
This is a small, early-stage study with only 62 people. The effects may be short-lived or not better than placebo, and individual results vary.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 62 people

The number the study aims to enrol. It can still change while the study runs.

Started

Sep 2025

Expected to finish

Dec 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 to 65 years

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * (1) Age between 18 and 65 years; (2) Patients whose diagnosis is consistent with the tardive dyskinesia (TD) diagnostic criteria defined by the Schooler-Kane criteria, with a disease duration of at least 3 months before screening, and a history of treatment with dopamine receptor antagonists for at least 3 months (a minimum of 1 month for patients aged ≥ 60 years); other diseases that may cause involuntary movements are excluded Exclusion Criteria:(1) Diagnosed with movement disorders other than tardive dyskinesia (TD); (2) A history of focal brain injury or severe leukoencephalopathy (Fazekas grade 3 or higher) identified on previous head MRI/CT; (3) A personal history of epilepsy, unexplained loss of consciousness, or current use of anticonvulsant medications for seizure management; (4) Presence of metallic medical devices in the body (e.g., cardiac pacemakers, cochlear implants), other metallic foreign bodies, or any electronic devices implanted in the body; or having other contraindications to repetitive Transcranial Magnetic Stimulation (rTMS); (5) Presence of contraindications to MRI scanning, such as having metallic implants in the body or claustrophobia \-
