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
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 Results may not be published yet.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 This study
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This status has not been confirmed recently, so it may be out of date.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 aimed to see if two advanced imaging modes, TXI and RDI, built into standard colonoscopy equipment, could make removing large colon polyps faster and safer. The trial was planned for adults with polyps 20 mm or larger, but it was withdrawn before any participants were enrolled. No drugs or devices were tested—only software-based image enhancements.

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 study could show that using TXI and RDI during colonoscopy reduces procedure time and lowers the risk of bleeding or polyp regrowth, leading to safer, more effective polyp removal without extra cost or devices.
What could go wrong
This is a small, single-center study that was withdrawn before enrolling any participants, so no results are available. The imaging tools are already FDA-cleared, but the structured workflow may not prove beneficial in larger, more diverse settings.

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.

Expected to start

Jan 2026

An estimate. Start dates often move.

Expected to finish

Dec 2027

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.

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

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

Show the full entry requirements

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

Inclusion Criteria: * Adults aged 18 years or older. * Undergoing elective colonoscopy at the Medical College of Wisconsin. * Presence of one or more large (≥20 mm) nonpedunculated colorectal polyps identified for endoscopic mucosal resection (EMR). * EMR performed using an Olympus EVIS X1 endoscopy platform with TXI and RDI imaging capability. * Able and willing to provide written informed consent for study participation, including collection of procedural imaging and clinical follow-up dat Exclusion Criteria: * Procedures performed using older-generation endoscopy systems without TXI or RDI functionality. * Polyps that are pedunculated, invasive, or require surgical resection rather than EMR. * Patients unable or unwilling to provide consent for participation or video capture. * Known pregnancy at the time of procedure. * Patients incarcerated or under custodial supervision. * Inability to tolerate bowel preparation, sedation, or standard EMR procedure due to comorbid conditions. * Incomplete colonoscopy or procedure aborted prior to resection for any reason.
