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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study is testing whether special light-based devices can detect cervical cancer by identifying unique optical signatures of abnormal tissue. Researchers will use three different devices—a bench-top spectrometer, a portable spectrometer, and a pocket-sized colposcope—on 350 women already scheduled for colposcopy, LEEP, or follow-up Pap smears. The goal is to see if these tools can accurately spot cervical dysplasia without needing a biopsy.

What this could mean

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

What this could lead to
If successful, this could lead to a faster, non-invasive way to detect cervical cancer during a routine exam.
What could go wrong
This is an early-stage study focused on finding light patterns, not yet proving the device works in real-world screening. Results may not lead to a commercial test.

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 350 people

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

Started

May 2006

Expected to finish

Jan 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.

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

Female participants only

Healthy volunteers

Accepted

You do not need to have the condition being studied to take part.

Inclusion Criteria: * undergoing colposcopy for the diagnosis of cervical cancer * LEEP for the treatment of cervical cancer in early stages. * Follow-up Pap smear in surveillance Exclusion Criteria: * Women under the age of 18 (minors) will be excluded from this study. * patients will be excluded if she has had a recent episode of bleeding or preterm labor. * Subjects who are not competent to give consent will excluded
