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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study tested a non-invasive optical device that uses different types of light to detect and diagnose various mouth conditions, including oral cancer, gum disease, and dry mouth. Over 1,000 participants with and without oral lesions were imaged, and the results were compared to standard diagnostic methods like biopsies. The goal was to develop a painless, patient-specific screening tool for early detection of oral pathology.

What this could mean

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

Active substance
non-invasive optical imaging device
What this could lead to
If successful, this could lead to a painless, light-based tool for early detection of oral cancers and other mouth diseases.
What could go wrong
This is an early-stage observational study focused on developing the technology, not testing a treatment. 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

The number who actually took part.

Start date

Apr 2003

Finished

Mar 2026

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.

This study's own entry requirements. Only the study team can say for certain whether you qualify.
