About this study

Official title: Open Label, Prospective, Cross-Sectional Clinical Performance Study of the in Vitro Diagnostic Device NK VueTM: Measurement of Natural Killer Cell Activity in Whole Blood in Men Being Screened for Prostate Cancer With Biopsy

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 prostate cancer using prostate biopsy.

Read the detailed description

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 affected.

Being tested

What participants receive

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

  • IVDD for NK cell activity in whole bloodDiagnostic test

    Also called NK Vue

    Two samples of one mL of blood (for baseline IFN-gamma activity and for NK cell activity) and blood samples collected for C-Reactive Protein and White Blood Cell Count, taken up to 8 weeks prior to biopsy and before treatment with antibiotics.

What is being measured

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

  1. The ability of NK cell activity to predict prostate cancer (yes/no) on biopsy

    Test performance of NK Vue will be assessed by logistic regression, both unadjusted and adjusted for the effects of at least PSA, age, digital rectal examination, and family history

    Measured: NK cell activity is measured up to 8 weeks prior to biopsy and prior to starting any antibiotic treatment

Secondary outcomes (3)
  1. The ability of NK cell activity to predict tumor grade (Gleason 2-6 vs. no cancer; Gleason 7-10 vs. no cancer)

    Test performance of NK Vue will be assessed by multinomial logistic regression, using the following known predictors of prostate cancer: age, ethnicity, PSA history, family history of prostate cancer, prostate volume, digital rectal examination findings, and number of prior biopsies.

    Measured: NK cell activity is measured up to 8 weeks prior to biopsy and prior to starting any antibiotic treatment

  2. Test performance metrics of NK Vue and PSA (each alone)

    The sensitivity, specificity, positive and negative predictive values for the detection of prostate cancer, will be calculated using Receiver Operating Characteristics analysis (at a cut-off of 4 ng/mL for PSA and at a cut-off of 200 pg/mL for NK Vue). Other cut-offs may be used to perform additional statistical analyses for test performance.

    Measured: NK cell activity is measured up to 8 weeks prior to biopsy and prior to starting any antibiotic treatment

  3. Impact of combination of NK Vue and PSA on the test performance of PSA

    The sensitivity, specificity, positive and negative predictive values for the detection of prostate cancer, will be calculated using Receiver Operating Characteristics analysis under combined conditions.

    Measured: NK cell activity is measured up to 8 weeks prior to biopsy and prior to starting any antibiotic treatment

Questions about this trial

What is this clinical trial studying?

A study testing IVDD for NK cell activity in whole blood in people with Immunity, Innate and Prostatic Neoplasm, 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: stopped early, as of the sponsor's last update on 5 Jul 2019. 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 was stopped early (reason given: Lack of funding). Results are not available in the source record.

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?

The ability of NK cell activity to predict prostate cancer (yes/no) on biopsy (time frame: NK cell activity is measured up to 8 weeks prior to biopsy and prior to starting any antibiotic treatment). 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 NCT03242265, which also lists 2 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 5 Jul 2019.
