Multitarget Stool FIT-DNA Study for Colorectal Cancer Early Screening in China (CLEAR-C)

December 7, 2020 updated by: Ding Ke-Feng, Zhejiang University

Stool KRAS Mutation, BMP3/NDRG4 Methylation and FIT Panel Test for the Detection of Colorectal Advanced Neoplasia in High Risk Chinese Patients

The primary objective is to determine the diagnostic sensitivity and specificity of the newly developed multitarget FIT-DNA Colorectal Cancer (CRC) screening test (ColoClear) for detecting advanced neoplasia (including colorectal cancer and advanced adenomas) in high risk patients, using colonoscopy as the reference method. The secondary objective is to compare the screening performance of the multitarget FIT-DNA test with commercially available FIT (Fecal Immunochemical Test) assay in detecting advanced neoplasia.

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

The study will be carried out in 8 tier-3A hospitals throughout China. Patients who are at high risk of developing colorectal cancer and willing to conduct colonoscopy examination will be asked to collect stool sample prior to bowl preparation for multitarget FIT-DNA test and commercially available FIT assay. Colonoscopy and histopathologic examination are used as reference.

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

36 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

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
Sensitivity and specificity of the ColoClear screening test with comparison to colonoscopy
Time Frame: Through study completion, an average of 1 year
A diagnostic colonoscopy procedure is the reference method. Lesions will be confirmed as malignant by histopathologic examination. The DNA test includes molecular assays for KRAS mutations, aberrant NDRG4 and BMP3 methylation, plus a hemoglobin immunoassay. A logistic-regression algorithm incorporating all the above parameters was deployed to compute a single composite score, with values of 165 or more considered to be positive. The tests were processed independently of colonoscopy procedure.
Through study completion, an average of 1 year

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
Sensitivity of the ColoClear screening test with comparison to FIT, with respect to advanced adenoma (AA) and CRC
Time Frame: Through study completion, an average of 1 year
A diagnostic colonoscopy procedure is the reference method. Lesions will be confirmed as malignant by histopathologic examination. The ColoClear and FIT test were performed on the same stool sample.
Through study completion, an average of 1 year
