About this study

Official title: Open Label, Prospective, Cross-Sectional Clinical Performance Study of the in Vitro Diagnostic Device NK Vue Kit: Measurement of Natural Killer Cell Activity in Whole Blood in Subjects Being Screened for Colorectal Cancer Using Colonoscopy

This study will look at measuring the activity of natural killer (NK) cells using the in vitro diagnostic device NK Vue in subjects being screened for colorectal cancer using colonoscopy. The NK Vue diagnostic test for natural killer cell activity uses the principle of stimulation of whole blood with a proprietary cytokine followed by the quantitative detection of interferon gamma using an immunoassay. NK Vue is intended to be used for the monitoring of the immune status of individuals. Measurement of NK cell activity could be a useful tool for assessing changes in immunosurveillance in patients with conditions or diseases where NK cell activity has been shown to be reduced, such as colorectal cancer.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • NK Vue: NK cell activity in stimulated whole bloodDevice

    One mL of blood is collected from each subject, on the day of colonoscopy, using NK Vue Promoca Tubes blood collection tubes containing a proprietary stimulating cytokine. After incubation, NK cell activity is measured in the collected plasma using an ELISA.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. NK cell activity

    Measurement of NK cell activity in subjects with cancer-negative colonoscopies versus those with pathologically confirmed colorectal cancer.

    Correlation of NK cell activity with polyp size, with type of adenomatous polyp and with cancer stage; measurement of the sensitivity and specificity of NK Vue; determination of the positive predictive value of NK Vue alone or in combination with the fecal immunochemical test in those subjects positive for adenomatous polyps or cancer; determination of the impact of performing both NK Vue and the fecal test on the sensitivity of the fecal test.

    Measured: Blood drawn for NK cell activity on day of colonoscopy

Questions about this trial

What is this clinical trial studying?

A study testing NK Vue: NK cell activity in stimulated whole blood in people with Natural Killer Cell Cytokine Production, run by ATGen Canada Inc at 1 site in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Aug 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

NK cell activity (time frame: Blood drawn for NK cell activity on day of colonoscopy). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02291198, which also lists 7 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Aug 2017.
