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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial tests whether repetitive transcranial magnetic stimulation (rTMS) can reduce or delay the involuntary movements, called dyskinesia, that many Parkinson's patients develop after taking levodopa. Researchers will apply targeted magnetic pulses to a brain region involved in movement planning, the pre-supplementary motor area, in about 68 people with Parkinson's who experience these peak-dose movements. Half will receive real stimulation and half a sham version, allowing a fair comparison of effects on dyskinesia severity and onset time.

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) using a MagVenture device, targeting the pre-supplementary motor area of the brain
What this could lead to
If it works, this could offer a non-drug way to ease the involuntary movements that many Parkinson's patients experience when their levodopa medication kicks in.
What could go wrong
This is an early-stage trial with a modest number of participants, and the effect may be small or short-lived. Brain stimulation can also cause discomfort or, rarely, seizures.

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 68 people

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

Started

Aug 2024

Expected to finish

Dec 2027

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 80 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.

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

Inclusion Criteria: * Clinically established or probable PD * Clinical Diagnostic Criteria for Parkinson's Disease * Peak-of-dose levodopa-induced dyskinesia. * Stable antiparkinsonian medicine for at least four weeks. * Signed informed consent. Exclusion Criteria: * Psychiatric disorders. * Usage of antipsychotic medication, Donepezil, and GABAergic medications (such as pregabalin and gabapentin). * Regular usage of benzodiazepines and opioids (more than once per week). * History of neurological disease other than Parkinson's disease. * History of epilepsy/conditions associated with increased risk to seizure-induction through TMS. * Close relatives suffering from epilepsy/conditions associated with increased risk to seizure-induction through TMS. * Contraindications for MRI scan * Female participants of childbearing age must not be pregnant and that they must use contraception during the trial. * Refuse to be informed about new health related information and accidental health related findings that might appear through participation in the study.
