What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 tested whether using a special scanner (O-ARM) in the operating room is as good as standard imaging done before surgery for placing brain electrodes in Parkinson's patients. 24 people took part, and researchers measured how accurately the electrodes were placed. The goal was to see if the O-ARM method could make the procedure more efficient without losing accuracy.

What this could mean

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

What this could lead to
If successful, this could show that using O-ARM imaging during surgery is just as accurate as standard imaging, potentially simplifying the procedure.
What could go wrong
This is a small, completed study with only 24 participants, so results may not apply to all patients. It compares imaging techniques, not a new treatment.

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

24 people

The number who actually took part.

Finished

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 75 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: * Patients with a diagnosis of idiopathic Parkinson's disease at the stage of motor fluctuations despite optimal medical treatment * Indication for Deep Brain Stimulation (DBS) of the subthalamic nucleus approved by the local multidisciplinary deep brain stimulation committee after an operability assessment (see Appendix) * Informed and signed patient consent * Affiliation to a social security scheme Exclusion Criteria: * Significant cognitive decline assessed in a dedicated multidisciplinary consultation * Contraindication to Magnetic Resonance Imaging (MRI) * Presence of pathologies contraindicating deep brain stimulation * No contraceptive treatment for women of childbearing age * Pregnant or breastfeeding woman * Anticoagulant or antiaggregant treatment that cannot be stopped * Persons under legal protection (persons deprived of liberty or incapable of giving consent or under guardianship or tutelage...) * Patient with severe psychiatric disorders
