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 Results may not be published yet.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.
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This status has not been confirmed recently, so it may be out of date.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

Researchers at the University of Houston are testing a forehead-worn device that records brain waves during sleep and plays brief, quiet pink-noise sounds timed to specific sleep stages. About 30 healthy adults aged 18 to 30 will use the system at home for up to 12 weeks and complete smartphone surveys about sleep, mood, stress, and memory. The pilot study measures whether people can use the device consistently, how well it reads brain signals and detects sleep stages, and whether the sound delivery is safe and tolerable. The team states the study is meant to refine the device and procedures, not to determine whether it treats depression or any medical condition.

What this could mean

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

Active substance
a forehead-worn wearable that records brain waves during sleep and plays brief, low-volume pink-noise sounds timed to specific sleep stages
What this could lead to
If the device proves easy to use and its sleep tracking works, it could support larger studies of whether gentle sound timed to deep sleep affects mood and memory.
What could go wrong
This is a small, early pilot with 30 healthy young adults, and researchers state it is not designed to show whether the system treats depression or any condition. Home use may prove inconsistent, and the sound timing may not change mood at all.

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 30 people

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

Expected to start

Apr 2027

An estimate. Start dates often move.

Expected to finish

Jun 2028

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.

Exclusion Criteria: * Diagnosed sleep disorder, including insomnia or sleep apnea. * Diagnosed psychiatric condition, including major depressive disorder or an anxiety disorder. * Neurological disorder, including epilepsy, seizure disorder, or significant traumatic brain injury. * Hearing impairment that would interfere with auditory stimulation. * Use of medication expected to substantially affect sleep, mood, or study outcomes, including sedative-hypnotic or relevant psychoactive medication. * Known allergy or sensitivity to device materials, adhesives, conductive materials, or other skin-contact components. * Current pregnancy. * Cognitive impairment or another condition preventing independent consent. Prisoner status. * Student or employee over whom the investigator or study personnel have direct grading, supervisory, employment, or evaluative authority. * Acute illness, dizziness, significant headache or earache, excessive fatigue, or another temporary safety or data-quality concern at the time of study procedures.
