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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 pilot study is testing whether personalized deep brain stimulation (DBS) patterns can better control Parkinson's motor symptoms while causing fewer side effects than standard settings. Researchers will enroll 10 people already implanted with the Medtronic Percept PC DBS device and compare their usual stimulation with new, patient-tailored patterns. The goal is to see if targeting excessive brain synchrony more precisely leads to smoother movement and less discomfort.

What this could mean

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

Active substance
novel deep brain stimulation patterns delivered via the Medtronic Percept PC device
What this could lead to
If successful, this could point toward more effective and personalized DBS therapy for Parkinson's disease with fewer side effects.
What could go wrong
This is a very small, early feasibility pilot with only 10 participants, so results may not apply broadly. The novel patterns may not work better than standard stimulation.

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 10 people

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

Started

May 2021

Expected to finish

Apr 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

19 to 80 years

Anyone

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

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: * Patients with idiopathic Parkinson's Disease who were recommended for STN DBS using standard clinical inclusion and exclusion criteria (e.g., presence of coagulopathy, dementia, untreated depression, pre-existing implanted stimulation system, prior intracranial surgery, history of alcohol or drug abuse) * Patients have been previously implanted with bilateral STN DBS and the Medtronic Percept PC implantable neural stimulator. * Patients are optimized for clinical stimulation and medication for at least 3 months post-surgery for the implantation of their DBS system. * Consent to study participation * Presence of a robust beta peak (detectable using the Percept BrainSense Survey feature; ≥ 0.7 µV/rtHz), intra-operatively (assessed via Lead Confirm technology from Alpha Omega) * Good response to stimulation (30% improvement on UPDRS III compared to baseline OFF), at least 3 months post-surgery. Exclusion Criteria: * Not currently implanted with the Medtronic Percept INS * Not willing to participate in the study * Unstable stimulation with need for frequent reprogramming or further adjustment * Significant stimulation-induced side effects * Need for unusual programming parameters such as very high (\> 200 Hz) or low (\< 100) frequencies (due to cycle limitations) * The patient has an implanted cardiac device * The patients Medtronic Percept TM PC indicates elective-replacement-indicated (ERI) at the start of the study
