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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 compares two methods for removing certain types of colon polyps (10-19mm adenomas or serrated lesions 10mm or larger) during a colonoscopy: cold snare piecemeal resection (CSPR) and cold snare endoscopic mucosal resection (Cold EMR). About 570 adults will take part to see which method removes polyps more completely and safely. The goal is to improve colon cancer prevention by finding the best technique.

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

Inclusion Criteria: 1. ≥ 18 years of age 2. Presenting for a screening, surveillance, diagnostic, or therapeutic colonoscopy 3. Found to have: * a sessile serrated lesion or hyperplastic polyp ≥ 10 mm during procedure (Serrated Cohort) or * a 10-19 mm conventional adenoma during procedure (Adenoma Cohort) 4. Ability to provide informed consent Exclusion Criteria: 1. Pedunculated or semi-pedunculated polyps (as defined by Paris Classification type Ip or Isp) 2. Polyps confirmed to be anything other than: * sessile serrated lesion or hyperplastic polyp on histologic diagnosis (Serrated Cohort) or * conventional adenoma on histologic diagnosis (Adenoma Cohort) 3. Patients with Ulcerative Colitis or Crohn's disease 4. Polyps with features suggestive of submucosal invasion 5. Polyps that are not able to be removed endoscopically due to location (e.g. extending into appendiceal orifice or diverticulum) 6. Patients with a known or suspected diagnosis of any of the following polyposis syndromes with known genetic mutations: * Familial Adenomatous Polyposis Syndrome * MUTYH associated Polyposis Syndrome * Juvenile Polyposis Syndrome * Cowden's Syndrome * Peutz-Jeghers Syndrome 7. Subjects whose colonoscopy procedure is not able to be completed due to bowel prep precluding polyp identification.
