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.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Patients aged between 45 and 84, who are at average risk of developing colorectal cancer, and are scheduled for a standard-of-care screening colonoscopy.

Approximately 12,000 subjects will need to be enrolled. Enrollment is event-driven and will be stopped when the required number of CRC cases have been confirmed with a final histopathological diagnosis.

Description

Inclusion Criteria:

  1. Subjects aged 45-84 years at time of consent
  2. Intended to undergo a standard-of-care screening colonoscopy
  3. Considered by a physician or healthcare provider as being of 'average risk' for CRC
  4. Willing to consent to blood draw prior to bowel preparatory procedures or undergoing colonoscopy ideally within 90 days of the date of the investigational blood draw.
  5. Willing to consent to follow-up for one year as per protocol
  6. Able and willing to sign informed consent

Exclusion Criteria:

  1. Undergoing colonoscopy for investigation of CRC risk symptoms
  2. Has undergone colonoscopy within preceding 9 years
  3. Positive FIT/FOBT result within the previous 12 months (+/- 3 months)
  4. Has completed Cologuard or Epi proColon testing within the previous 3 years.
  5. Has undergone a CT colonography in the prior 4 years.
  6. History of colorectal cancer.
  7. History of any malignancy within prior 5 years.
  8. Known diagnosis of inflammatory bowel disease (IBD), including chronic ulcerative colitis (CUC) and Crohn's disease (CD).
  9. Positive family history of colorectal cancer, defined as having a first- degree relative (parent, sibling, or child) with CRC diagnosed at age <60 years or with more than one first-degree relative diagnosed with CRC at any age.
  10. Known hereditary/germline risk of colorectal cancer (for example, Lynch syndrome or Hereditary Non-Polyposis CRC [HNPCC], or Familial Adenomatous Polyposis [FAP]).
  11. Any major physical trauma (e.g., disruption of tissue, surgery, organ transplant, blood product transfusion) within the 30 days leading up to the provision of informed consent.
  12. Known medical condition which, in the opinion of the investigator, should preclude enrollment into the study.
  13. Known pregnancy at informed consent, blood sample collection, and during study participation.
  14. Participation in a clinical research study in which an experimental medication has been administered or may be administered within the 30 days leading up to providing informed consent or may be administered through the time of colonoscopy.

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.
Average risk
Patients aged between 45 and 84, who are at average risk of developing colorectal cancer, and are scheduled for a standard-of-care screening colonoscopy.
Device: Signal-C™
Signal-C™ is a qualitative next generation sequencing-based in vitro diagnostic assay that uses targeted hybridization-based capture next-generation sequencing together with bioinformatics and machine learning algorithm for detection and combination of methylation and fragmentation associated DNA marker regions. Signal-C™ utilizes circulating cell-free DNA (cfDNA) isolated from plasma of peripheral whole blood collected via venipuncture in Streck Cell-Free DNA Blood Collection Tubes (BCTs).

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
Primary Objective
Time Frame: 1 year
The primary objective of this study is to determine the sensitivity for CRC and specificity for advanced neoplasia (AN). Advance Neoplasia (AN) is defined as a final diagnosis of CRC or Advanced Precancerous Lesion (APL).
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
Secondary Objective
Time Frame: 1 year
To determine sensitivity for advanced precancerous lesions (APL). To determine NPV and PPV for colorectal cancer.
1 year

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 18, 2024

Primary Completion (Estimated)

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.

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
