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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 follows 404 people who previously had either an AI-assisted or conventional colonoscopy. Researchers want to see if AI help lowers the risk of developing advanced colon polyps later. Participants will undergo a surveillance colonoscopy to check for new growths.

What this could mean

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

Active substance
artificial intelligence-assisted colonoscopy
What this could lead to
If successful, this could show that AI helps doctors find more polyps during colonoscopy, lowering the chance of future advanced growths and improving cancer prevention.
What could go wrong
This is an observational follow-up, not a new treatment test. The AI was used only in the initial colonoscopy, so benefits may be limited or not apply to everyone.

This is an AI summary of the original study and may miss details. Read our disclaimer.

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 404 people

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

Started

Jul 2025

Expected to finish

Feb 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

Anyone

Healthy volunteers

Accepted

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

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Eligible participants are those who were previously enrolled and completed our randomized controlled trial comparing AI-assisted and conventional colonoscopy Exclusion Criteria: * In addition to the baseline exclusion criteria of the index trial, patients who were found to have inflammatory bowel disease, colorectal cancer and underwent bowel resection would be excluded. Similar to index trial, patients who have developed severe comorbid illnesses that make surveillance colonoscopy and polypectomy unsafe, or become unable to provide informed consent for trial participation would also be excluded Index trial: Lui TK, Lam CP, To EW, Ko MK, Tsui VWM, Liu KS, et al.
