Trial summary

This protocol will be used to collect crucial components of the immune system from healthy volunteers for the characterization of immune cells in fresh blood. A pipeline has been set up for comprehensive immune phenotyping of both lymphoid and myeloid cells within 24 hours after blood withdrawal. Read more about this study

About this study

This protocol will be used to collect crucial components of the immune system from healthy volunteers for the characterization of immune cells in fresh blood. A pipeline has been set up for comprehensive immune phenotyping of both lymphoid and myeloid cells within 24 hours after blood withdrawal.

Read the detailed description

In order to properly compare the immunobiology of healthy volunteers to (advanced) cancer patients, the investigators use age-matched controls with no history of cancer and no potentially interfering medication.

Healthy volunteers will be asked to donate 5 tubes of blood

What is being measured

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

  1. The number of immune cells, both lymphoid and myeloid, present in the blood of healthy individuals, assessed by flow cytometry, as well as cytokine expression and transcriptome profiles of these cells

    the number of lymphoid and myeloid immune cells present in the blood of healthy individuals using flow cytometry, assessing the cytokine expression of these cells in healthy individuals using ELISA cytokine assays, and assessing gene expression of these cells using single cell transcriptomics analyses using droplet-based single cell RNA sequencing.

    Measured: assessed up to 12 months

Secondary outcomes (1)
  1. Immunophenotyping of both myeloid and lymphoid cells in healthy individuals

    Immunophenotyping of both myeloid and lymphoid cells in healthy controls to gain insights in immunological defects and immune evasion in cancer patients

    Measured: assessed up to 12 months

Questions about this trial

What is this clinical trial studying?

A study testing Blood sample in people with Healthy Volunteers, run by The Netherlands Cancer Institute at 1 site in Netherlands.

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 4 inclusion and 3 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: looking for participants now, as of the sponsor's last update on 23 Mar 2023. 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 Netherlands. 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?

This study is still under way. Results are not available in the source record yet.

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

Contact M Kok, MD (3120512 ext. 9111, m.kok@nki.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The number of immune cells, both lymphoid and myeloid, present in the blood of healthy individuals, assessed by flow cytometry, as well as cytokine expression and transcriptome profiles of these cells (time frame: assessed up to 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 23 Mar 2023.
