Trial summary

The goal of this randomized clinical trial is to learn if a combination of hot and cold EMR technique is associated with a lower risk of polyp recurrence without increasing the risk of complication when removing large polyps. Read more about this study

About this study

The goal of this randomized clinical trial is to learn if a combination of hot and cold EMR technique is associated with a lower risk of polyp recurrence without increasing the risk of complication when removing large polyps.

Participants will undergo EMR and return for a follow-up endoscopy in 3-6 months to check for polyp recurrence.

Being tested
Cold EMR, Hybrid EMR

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Cold EMRProcedure or surgery

    Cold EMR with cold forceps (regular or jumbo forceps) removal of any visible neoplasia that cannot be ensnared.

  • Hybrid EMRProcedure or surgery

    Cold EMR with hot avulsion of any visible residual neoplasia within the resection bed, in addition to precise APC of the fibrotic bands that may harbor invisible neoplasia within the resection bed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Recurrence of polyps

    Recurrence of polyps confirmed by biopsy at the site of EMR on follow-up colonoscopy

    Measured: 3-6 months after the procedure

Secondary outcomes (4)
  1. Adverse events

    Composite of clinically important adverse events: (1) Perforation requiring hospitalization or surgery (2) Bleeding associated with at least 2-gram Hb drop or hospitalization or Intervention (3) Post-polypectomy syndrome requiring hospital admission

    Measured: 3-6 months after the procedure

  2. Polyp recurrence rates

    Recurrence of polyps confirmed by biopsy at the site of EMR on follow-up colonoscopy

    Measured: 3-6 months after EMR procedure

  3. Cost benefit analysis

    • Cost-benefit analysis includes the costs of additional hospitalizations related to post-procedure complications and the cost of additional colonoscopies required to follow up treatment of recurrence. Costs will be calculated from a Medicare perspective.

    Measured: 3-6 months after the procedure

  4. Subgroup polyp recurrence rate

    • Recurrence rates in the subgroup of patients with visible residual neoplasia after snare resection before utilizing forceps or cautery resection/ablation

    Measured: 3-6 months after the procedure

Questions about this trial

What is this clinical trial studying?

A study testing Cold EMR and Hybrid EMR in people with Polyp of Colon and Endoscopic Mucosal Resection, run by The Cleveland Clinic at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 29 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Akram Ahmad, M.D. (954-659-5000, ahmada5@ccf.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Recurrence of polyps (time frame: 3-6 months after the procedure). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jul 2026.
