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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial tests whether a non-invasive technique called temporally-interfering electric field stimulation (TIEFS) can reduce abnormal brain activity linked to epilepsy. Researchers will measure seizure-related signals in patients with medial temporal lobe epilepsy who are already undergoing brain monitoring. The study compares these signals during no stimulation, sham stimulation, and active TIEFS to see if the device can dampen them.

What this could mean

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

Active substance
temporally-interfering electric field stimulation (TIEFS), a non-invasive device that uses electric fields to modulate brain activity
What this could lead to
If effective, this could offer a non-invasive, drug-free way to reduce seizure-related brain activity, potentially leading to a new treatment for epilepsy.
What could go wrong
This is an early, exploratory study focused on brain signals, not seizure outcomes. The effect may not translate to real-world seizure reduction, and the device's safety and efficacy are not yet established.

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 100 people

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

Started

Jan 2019

Expected to finish

Jul 2030

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 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.
