EndoRings Colonoscopy vs Standard Colonoscopy

September 18, 2019 updated by: Douglas K. Rex, Indiana University

A Randomized Trial Comparing the Adenoma Detection Rates Between EndoRings Colonoscopy (EC) and Standard Colonoscopy (SC).

The study aims to compare the results between a standard colonoscopy to a colonoscopy with an attachment on the distal end of the colonoscope.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This will be a prospective, randomized controlled study. Subjects referred for screening or surveillance colonoscopy will be prospectively enrolled. This study aims to compare the adenoma detection rates between EndoRings colonoscopy (EC) and Standard colonoscopy (SC). It is assumed that the proportion of patients with at least one adenoma would be 25% with SC and 35% with EC.

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
592

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
No Intervention: Control Arm (Standard Colonoscopy)
Standard colonoscopy with no device attachment.
Experimental: EndoRings Colonoscopy
Colonoscopy with EndoRings device attached to the distal end of the scope.
Device: EndoRings device
Subjects randomized to undergo a colonoscopy procedure with the EndoRings device will have the device placed on the colonoscope that will be used during their procedure.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Adenoma Detection Rates
Time Frame: During colonoscopy procedure
Number of participants with at least one adenoma detected, during Standard Colonoscopy compared with colonoscopy with EndoRings.
During colonoscopy procedure
Number of Adenomas Per Colonoscopy
Time Frame: During colonoscopy procedure
Comparison of the number of adenomas detected per colonoscopy between standard colonoscopy and EndoRings colonoscopy.
During colonoscopy procedure

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Polyp Detection Rate
Time Frame: During colonoscopy procedure
Number of subjects with at least one polyp detected with Standard Colonoscopy compared to colonoscopy with EndoRings.
During colonoscopy procedure
Number of Detections Per Colonoscopy
Time Frame: During colonoscopy procedure
Comparison of the number of polyps detected per colonoscopy between EndoRings colonoscopy and Standard colonoscopy.
During colonoscopy procedure
Total Number of Detections
Time Frame: During colonoscopy procedure
Comparison of the total number of polyps detected and the total number of adenomas detected between EndoRings colonoscopy and Standard colonoscopy.
During colonoscopy procedure
Cecal Intubation Rate
Time Frame: During colonoscopy procedure
Comparison of cecal intubation rate (the number of procedures where the colonoscope was able to be inserted all the way to the cecum) between standard colonoscopy and EndoRings colonoscopy.
During colonoscopy procedure
Time Comparison for Each Method
Time Frame: During colonoscopy procedure

Comparison of the time required to reach the cecum, withdrawal time, and total procedure time.

Insertion time: time required to reach the cecum Withdrawal time: time calculated from when withdrawing is started in the cecum till the colonoscope is removed. This includes time spent washing, inspecting the colon and removing polyps.

Total procedure time: This is the sum of insertion and withdrawal times along with any time spent washing or removing polyps while in the cecum (before starting withdrawal).
During colonoscopy procedure
Patient Comfort Score
Time Frame: After colonoscopy was completed while patient was in recovery area of endoscopy unit
Comparison of patient comfort between Standard colonoscopy and EndoRings colonoscopy on a scale of 0 to 10 with 0 being no pain (best outcome) and 10 being worst imaginable pain (worst outcome).
After colonoscopy was completed while patient was in recovery area of endoscopy unit
Problems Encountered With Equipment
Time Frame: During colonoscopy procedure
Occurrences of slippage of EndoRings or of device being removed on insertion.
During colonoscopy procedure

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
