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 This study
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 Results may not be published yet.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

Summary

This study compares a new bipolar knife to a standard monopolar knife for removing colon polyps using a procedure called endoscopic submucosal dissection (ESD). About 80 adults with colon growths will be randomly assigned to one knife. Researchers will measure how fast the procedure goes and check for complications like bleeding or pain. The goal is to see if the new knife is safer or more efficient.

What this could mean

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

Active substance
bipolar radiofrequency ablation knife
What this could lead to
If the bipolar knife works better, it could make colon polyp removal faster and reduce complications like bleeding or pain.
What could go wrong
This is a small, early-stage trial with only 80 people. The new knife may not be faster or safer than the standard one, and results may not apply to all patients.
