Brief Summary
This is a prospective, multicenter, randomized controlled study to evaluate the effect of the Computer-Assisted Detection (CADe) Device on Adenomas Per Colonoscopy and Positive Percent Agreement for routine colonoscopies. The control arm is colonoscopy performed with High Definition White Light Endoscopy (HD-WLE) per standard of care. The intervention arm is colonoscopy performed with HD-WLE per standard of care plus the Computer-Assisted Detection (CADe) Device.

Outcome Measures
Primary Outcomes (2)
Difference in Adenomas Per Colonoscopy (APC)
Difference in Adenomas Per Colonoscopy (APC) between the control and intervention arm, evaluated for superiority. APC is defined as the average number of histologically confirmed adenomas resected per colonoscopy.
Day 1
Difference in Positive Percent Agreement (PPA)
Difference in Positive Percent Agreement (PPA) between the control and intervention arm, evaluated for non-inferiority. PPA is defined as the total number of histologically confirmed Clinically Significant Excised Lesions, divided by the total number of excisions.
Day 1
Secondary Outcomes (13)
Adenoma Detection Rate (ADR)
Day 1
Number of False Alerts Per Procedure

Study Arms (2)
Colonoscopy (Standard of Care)
NO INTERVENTIONThe control arm is colonoscopy with High Definition White Light Endoscopy (HD-WLE) per standard of care.
CADe Device
EXPERIMENTALThe intervention arm is colonoscopy with HD-WLE per standard of care plus the CADe Device.
Interventions
The CADe Device uses artificial intelligence to aid in identifying colorectal polyps during High Definition White Light Endoscopy (HD-WLE) based colonoscopies. This device connects the Gastroenterologist's colonoscopy video output source to the main monitor and highlights the regions of interest where the device detects a potential lesion. The CADe Device overlays graphical markers onto video from the endoscope camera and does not perform further processing to the endoscope video signal. This device is not intended to replace clinical decision making.
Eligibility Criteria
You may qualify if:
- Scheduled to undergo routine screening (including, but not limited to, FIT/Cologuard positive), routine surveillance (≥3 years as scheduled since last colonoscopy), or diagnostic (symptomatic) colonoscopy with High Definition White Light Endoscopy.
- Between the ages of 45 and 80 years, inclusive
- Able and willing to provide written informed consent
You may not qualify if:
- Self-reported pregnancy
- Known diagnosis of Colorectal Cancer
- History of, or referral for, Inflammatory Bowel Disease
- Previous surgery involving the colon or rectum
- Referral for known polyp or assessment of post-polypectomy site (i.e. less than 3 years since last colonoscopy).
- High suspicion or diagnosis of genetic polyposis syndromes, including familial adenomatous polyposis (FAP), hereditary nonpolyposis colorectal cancer (HNPCC), or any other high-risk family history meeting Bethesda guidelines.
- Referral for overt, symptomatic gastrointestinal bleeding

- Subjects, investigators, study site personnel, and pathologists will not be blinded to treatment assignments. All Verily personnel involved in the statistical analysis of this study will be blinded to treatment assignment. For the interim analysis, unblinded analysis will be performed by an independent statistician, the results of which will be communicated to a select group of Verily personnel not involved in the study management.
