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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 explores whether low-intensity focused ultrasound (LIFU) aimed at specific brain regions can influence how the body controls automatic functions like heart rate and blood pressure. Researchers will apply LIFU or a sham (fake) version to 80 volunteers and measure changes during a cold-water hand immersion test. The goal is to understand if this non-invasive technique can alter autonomic control, which could one day help people with autonomic dysfunction.

What this could mean

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

Active substance
Low-intensity focused ultrasound (LIFU) device
What this could lead to
If successful, this could point toward a non-invasive brain stimulation treatment for autonomic dysfunction.
What could go wrong
This is a small, early-stage study focused on measuring physiological responses, not treating disease. The intervention is experimental and may not produce meaningful clinical benefits.

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 80 people

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

Started

Feb 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 65 years

Sex

Anyone

Healthy volunteers

Accepted

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

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

Inclusion Criteria: * Does not meet exclusion criteria. Exclusion Criteria: The exclusion criteria below are regularly implemented in MRI, CT, and EEG experiments for the safety of the subjects and for data quality assurance. * Claustrophobia (scanning environment may be uncomfortable). * Contraindications to MRI: including pacemaker, aneurysm clips, neurostimulators, cochlear implants, metal in eyes, steel worker, or other implants. * Contraindications to CT: pregnancy * Active medical disorder or treatment with potential central nervous system (CNS) effects (e.g. Alzheimer's) - * History of neurologic disorder. (e.g. Parkinson's, Epilepsy, or Essential Tremor) * History of head injury resulting in loss of consciousness for \>10 minutes. * History of alcohol or drug dependence (through self-report). * History of cardiac disease * A current or prior use of any cardiac medication (e.g. beta blockers or other anti-arrhythmics) * A history of diabetes mellitus or use of diabetic medications (e.g. metformin).
