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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 early study tests whether wearing a small nerve-stimulating ear clip at night can safely reduce premature ventricular contractions (PVCs) — extra, often bothersome heartbeats. Sixteen adults with at least 5% PVC burden will use the Parasym device for 10 weeks. The main goals are to see if the device is safe, tolerable, and easy to use, while also tracking any changes in PVC frequency.

What this could mean

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

Active substance
auricular vagus nerve stimulator device (Parasym)
What this could lead to
If it works, this could point toward a non-drug, wearable treatment to reduce bothersome extra heartbeats (PVCs) and improve quality of life.
What could go wrong
This is a very early, small feasibility study with only 16 people. It mainly checks safety and comfort, not whether the device actually reduces PVCs. Results may not apply to everyone.

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

16 people

The number who actually took part.

Jul 2025

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 years and older

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 Individuals must meet all of the following inclusion criteria to be eligible to participate in this study: Age ≥ 18 years PVC burden ≥ 5% documented on an event monitor or implanted cardiac device Provide written informed consent Willingness to comply with all study procedures Availability for the duration of the study (10 weeks) Individuals meeting any of the following exclusion criteria at baseline will be excluded from study participation: Unwilling or unable to provide informed consent for oneself Last available left ventricular ejection fraction \< 20% NYHA Class IV symptoms Acute coronary syndrome within two weeks of randomization Active pregnancy or breastfeeding Intention to become pregnant Statement Regarding Equitable Selection: This study will not exclude specific populations based on age, sex, race, or ethnicity. The inclusion/exclusion criteria are based on clinical factors relevant to the study intervention and the safety of participants. Limited English proficiency will not be an exclusion criterion, and appropriate translation services will be provided to ensure informed consent and understanding of study procedures.
