Polyp REcognition Assisted by a Device Interactive Characterization Tool - The PREDICT Study (PREDICT)

May 10, 2021 updated by: Cosmo Artificial Intelligence-AI Ltd

Diminutive colorectal polyps (≤ 5 mm) represent most of the polyps detected during colonoscopy, especially in the rectum-sigmoid tract. The characterization of these polyps by virtual chromoendoscopy is recognized as a key element for innovative imaging techniques. As a matter of facts diminutive colorectal polyps are very frequent and, if located in the rectosigmoid colon, they present a very low malignant risk (0.3% of evolution towards advanced adenoma and up to 0.08% of evolution towards invasive carcinoma). The real-time characterization would allow to identify the lowest risk polyps (hyperplastic subtype), to leave them in situ or, if resected, not to send them for histological examination, allowing a huge saving in healthcare associated costs.

Recently, the American Society for Gastrointestinal Endoscopy (ASGE) Technology Committee established the Preservation and Incorporation of Valuable endoscopic Innovations (PIVI) document, specific for real-time histological assessment for tiny colorectal polyps, to establish reference quality thresholds. Two performance standards have been developed to guide the use of advanced imaging:

  1. for diminutive polyps to be resected and discarded without pathologic assessment, endoscopic technology (when used with high confidence) used to determine histology of polyps ≤ 5mm in size, when combined with the histopathology assessment of polyps > 5 mm in size, should provide a ≥ 90% agreement in assignment of post-polypectomy surveillance intervals when compared to decisions based on pathology assessment of all identified polyps;
  2. in order for a technology to be used to guide the decision to leave suspected rectosigmoid hyperplastic polyps ≤ 5 mm in size in place (without resection), the technology should provide ≥ 90% negative predictive value (when used with high confidence) for adenomatous histology.

Computer-Aided-Diagnosis (CAD) is an artificial intelligence-based tool that would allow rapid and objective characterization of these lesions. The GI Genius CADx was developed to help endoscopists in their clinical practices for polyps characterization.

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.

Study Population

Patients aged 40-80 undergoing colonoscopy

Description

Inclusion Criteria:

  • Patients aged 40-80 undergoing screening colonoscopy for CRC
  • Ability to provide written, informed consent (approved by EC) and understand the responsibilities of trial participation.

Exclusion Criteria:

  • subjects positive to Fecal Immunochemical Test or Fecal Occult Blood Test;
  • subjects undergoing CRC surveillance colonoscopy
  • subject at high risk for CRC
  • subjects with a personal history of CRC, IBD or hereditary polyposic or non-polyposic syndromes;
  • patients with previous resection of the sigmoid rectum;
  • patients on anticoagulant therapy, which precludes resection / removal operations due to histopathological findings;
  • patients who perform an emergency colonoscopy.

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
Time Frame
Negative Predictive Value of histology prediction on diminutive (≤5 mm) rectosigmoid polyps
Time Frame: 1 day
1 day

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
Agreement in assignment of post-polypectomy surveillance intervals
Time Frame: 1 day

Agreement in assignment of post-polypectomy surveillance intervals according to established guidelines between:

  • the assignment identified according to the combined

    • GI Genius CADx histology prediction for diminutive (≤5 mm) polyps and
    • histology for larger polyps (> 5 mm), and
  • the assignment identified according to histology only.
1 day

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
