Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

We will conduct a multicenter, parallel-group, non-inferiority RCT in persons with IBD undergoing colorectal neoplasia screening with high-definition white light colonoscopy, comparing a strategy of sampling visible lesions alone to a conventional strategy of sampling both visible lesions as well as normal-appearing mucosa using non-targeted biopsies. The primary outcome is the neoplasia detection rate. The required sample size to demonstrate non-inferiority is 1952 persons.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Experimental: Intervention Group

Participants will undergo standard colonoscopy as part of their routine IBD surveillance. During this colonoscopy targeted biopsies (biopsies of any pre-cancerous lesions observed by the doctor) and/or removal of any polyps will be undertaken.

Group Type EXPERIMENTAL

Standard colonoscopy with targeted biopsies

Intervention Type PROCEDURE

Participants will undergo standard colonoscopy as part of their routine IBD surveillance. During this colonoscopy targeted biopsies (biopsies of any pre-cancerous lesions observed by the doctor) and/or removal of any polyps will be undertaken.

Control Group

Participants will undergo standard colonoscopy as part of their routine IBD surveillance. During this colonoscopy both random (approximately 32 to 40) and targeted biopsies (and/or removal of any polyps) will be undertaken.

Group Type NO_INTERVENTION

No interventions assigned to this group

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Each potential participant must satisfy all of the following criteria to be enrolled in the study.

* ≥ 18 years old

* cIBD ≥ 8 years duration (or at any time after diagnosis if a patient also has primary sclerosing cholangitis)
* In symptomatic remission at time of colonoscopy

* For CD: Harvey-Bradshaw Index \< 541
* For UC or IBDU: Partial Mayo Score ≤ 242
* Major purpose of colonoscopy is neoplasia screening/surveillance
* Undergoing colonoscopy with high-definition white light endoscopy

Exclusion Criteria

* Persons who are unable to provide informed consent
* Persons with a history of colorectal cancer
* Persons with prior subtotal or total colectomy (\>50% of colon removed)
* Persons undergoing repeat colonoscopy to follow-up on recently diagnosed neoplasia identified within the past year
* Persons undergoing pancolonic chromoendoscopy or pancolonic virtual chromoendoscopy
* Colon mucosa visibility deemed inadequate for surveillance after washing/suctioning (Boston Bowel Preparation Score of 0 or 1 in any segment)
* Incomplete colonoscopy (unable to reach cecum or terminal ileum \[if no cecum\])
* Moderate-to-severe inflammation (Mayo 2-3) involving ≥ 25% of colorectum or mild inflammation (Mayo 1) involving ≥ 50% of colorectum
