NCT ID NCT04061148

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

Researchers at the University of California, San Francisco are testing whether a device called NIRSIT can measure depression severity by shining near infrared light through the forehead to track blood oxygen levels in the frontal lobe. The study compares adults diagnosed with Major Depressive Disorder to non-depressed volunteers. Participants perform thinking and humor tasks while the device records brain activity, and researchers check whether these readings change as depression treatment progresses over six weeks.

What this could mean

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

Active substance
NIRSIT, a non-invasive device that uses near infrared light to measure blood oxygen in the frontal lobe
What this could lead to
If it works, doctors could one day use a quick, non-invasive brain scan to help diagnose depression and track whether treatment is working.
What could go wrong
This is an early diagnostic study with 90 participants. Brain blood-flow patterns may not reliably distinguish depression from other conditions, and the device may not prove accurate enough for routine clinical use.

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 90 people

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

Started

Jan 2019

Expected to finish

Dec 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.
