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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 a device that gently stimulates a nerve in the ear is safe and tolerable for people with chronic kidney disease (CKD). Twenty adults with moderate to advanced CKD will use the device for 15 minutes. Researchers will measure heart rate changes and blood pressure to see if the device might help reduce heart risks in the future.

What this could mean

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

Active substance
transcutaneous auricular vagus nerve stimulation device (TENS unit)
What this could lead to
If this pilot shows promise, it could lead to a larger study testing whether nerve stimulation can reduce heart-related risks in people with chronic kidney disease.
What could go wrong
This is a very early, small pilot study with only 20 participants. It is designed to test feasibility and safety, not to prove the treatment works. The device may have no meaningful effect.

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 20 people

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

Started

Aug 2023

Expected to finish

Jan 2026

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.

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: • Individual 18-80 years of age with CKD stage 3-5 (eGFR \<60 mL/min/1.73m2) on most recent outpatient labs. Exclusion Criteria: * Pacemaker dependent * Prisoners * Pregnant women. A pregnancy test will be offered if a subject is concerned about being pregnant. * Not capable of informed consent * Know autonomic function disorder (e.g. Parkinson's disease with autonomic dysfunction) * ICD or PPM precluding assessment of heart rate variability (e.g. chronic atrial fibrillation) * Recent myocardial infarction (4 weeks or less) * Maintenance dialysis * Epilepsy * Patients on labetalol (labetalol will interfere with catecholamine measurements) * Patients with diabetes * At least 50% of cohort must not be on beta blockers. This will help to distinguish the confounding effects of beta blockers.
