Real-time Computer Aided Detection of Barrett's Neoplasia: a Pilot Study

In the real-time pilot study, the performance of a recently developed Computer Aided Detection (CADe) system will be investigated in 30 patients during real-time live endoscopic examination. Three expert endoscopists in the field of Barrett's esophagus and endoscopic resection techniques will perform the inclusions following a standardized data acquisition protocol. In total, 15 patients with a visible neoplastic lesion in their Barrett's esophagus and 15 patients without any visible abnormalities in their Barrett's esophagus will be included in this study. Outcomes: to investigate feasibility of the use of the CADe system in the endoscopy suite, to investigate the performance of the CADe system when used by endoscopists.

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

Patients in this study will undergo a scheduled surveillance endoscopy (according to current guidelines; n = 15) or are referred to a tertiary referral center for endoscopic resection of a possible neoplastic area in their known Barrett's esophagus (n = 15).

Patients will be consciously sedated (standard care) before start of the procedure. During the endoscopic procedure, the endoscopist follows the standard protocol after extensive cleaning of the Barrett's segment: first, a standardized pullback video will be recorded, followed by a careful inspection of the Barrett segment every 2 centimeters. Per 2cm, a video of 10 seconds and 3 overview images are being recorded.

During the imaging protocol, the CADe system presents its prediction on a second screen, next to the main endoscopy monitor. After the imaging protocol, standard clinical care is being resumed.

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.

Ages Eligible for Study

18 years to 99 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

Patients diagnosed with Barrett's esophagus, either receiving a surveillance endoscopy according to protocol or referred for endoscopic treatment for proven neoplasia in their Barrett's esophagus

Description

Inclusion Criteria:

  • Age > 18 years;
  • Patients under surveillance for their diagnosed non-dysplastic Barrett's esophagus or patients refered for endoscopic treatment because of proven high-grade dysplasia or adenocarcinoma;
  • A circumferential Barrett length of at least 2cm

Exclusion Criteria:

  • Medical history of prior surgical or endoscopical treatment for neoplasia in their esophagus
  • Reflux esophagitis > grade 2 (LA classification)
  • Inability to undergo endoscopic treatment and/or biopsies

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
CADe system
All patients included in the study will undergo the endoscopic procedure according to standard clinical care and the study protocol. The CADe system will run in the back, not interfering with care.
Other: Computer Aided Detection system for Barrett's neoplasia
CADe system running in the back, not directly interfering with patient care

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
Combined performance of endoscopist + CADe system in terms of per-patient sensitivity and specificity
Time Frame: 5 months
To investigate the combined performance between endoscopist and CADe system on a per-patient level.
5 months

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
Stand-alone performance of CADe system in terms of per-patient sensitivity and specificity
Time Frame: 5 months
To investigate the performance of the CADe system on new data on a per-patient level.
5 months

Primary Completion (Actual)

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.
