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 This study
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 Results may not be published yet.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.

Summary

This trial tests whether a wearable device emitting near-infrared light during sleep can improve sleep quality and reduce the need for sedative-hypnotic medications in adults with chronic insomnia. Sixty adults who use sleeping pills at least four nights a week will use either the active light device or an inactive sham device while sleeping for eight weeks. Researchers will measure changes in sleep quality, medication use, daytime alertness, and mood. The goal is to see if this non-drug approach can be a safe, home-based alternative to long-term sleeping pill use.

What this could mean

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

Active substance
A wearable device that delivers near-infrared light (photobiomodulation) to acupoints during sleep
What this could lead to
If effective, this light-based approach could offer a drug-free way to improve sleep and help people reduce their reliance on sleeping pills.
What could go wrong
This is a small, early-stage trial, and the device's benefits are not yet proven. Some participants may not experience improvement, and the sham control helps test whether any effect is real.

Participants

About 60 people

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

Expected to start

Aug 2026

An estimate. Start dates often move.

Expected to finish

May 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.
