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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 small pilot study tests whether implanting electrodes in the cerebellum—a brain area that controls coordination—can safely improve walking and balance in people with severe ataxia that hasn't responded to other treatments. Twelve adults aged 20 to 70 with primary ataxia will receive deep brain stimulation (DBS) and be followed for one year. The main goal is to check safety, but researchers will also measure changes in coordination and gait.

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 12 people

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

Started

Mar 2023

Expected to finish

Dec 2035

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

20 to 70 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. Female or Male patients between age 20-70 2. Diagnosis of primary ataxia (inclusive of congenital and hereditary subtypes without other neurological compromise) 3. Head CT scan and cerebral MRI without any structural contraindications for safe DBS 4. Patient able to give written consent 5. Able to comply with all testing, follow-ups and study appointments and protocols Exclusion Criteria: 1. Active neurologic disease including but not limited to epilepsy and certain brain tumors 2. Secondary ataxia (such as due to stroke, medication, autoimmune disease, ischemia, tumor, or other lesion) 3. Any contraindication to MRI scanning 4. Likely to relocate or move during the study's one-year duration 5. Presence of cardiac arrhythmias, or other cardiac, respiratory, renal or endocrine conditions that will result in significant risk from a surgical procedure.
