About this study

Exploration of pathophysiological mechanisms in chronic inflammatory rheumatism and rare systemic autoimmune diseases with the objective of identifying therapeutic targets.

Read the detailed description

The primary objective is to characterization of the quantitative and qualitative specificities of the different leukocyte sub-populations in patients with chronic inflammatory rheumatism and rare systemic autoimmune diseases. We will perform an exploratory descriptive study whom primary endpoint will be to assess by FACS the phenotype of the specific leukocyte subsets. In addition, we will characterize the protein and transcriptomic signature associated with the conditions for which we have obtained preliminary data showing their potential involvement in autoimmunity (i.e: IL7 pathway, IFN signature).

What is being measured

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

  1. Characterization of the quantitative and qualitative specificities of the different leukocyte subpopulations in patients with chronic inflammatory rheumatism and rare systemic autoimmune diseases

    Proportion of different leukocytes subset

    Measured: At the end of the study (5 years)

Secondary outcomes (3)
  1. Protein study (ELISA on serum) : IL7

    levels of IL7 and other cytokines

    Measured: At the end of the study (5 years)

  2. Transcriptome study (RNA) : mRNA levels

    assessement of different mRRNA involved in Il7/IFN pathways by molecular biology techniques (RNAseq, qPCR, nano string)

    Measured: At the end of the study (5 years)

  3. Genomic study (DNA) : SNPs

    Determination of the genotype of different SNPs involved in IL7/IFN pathways

    Measured: At the end of the study (5 years)

Questions about this trial

What is this clinical trial studying?

An observational study of Systemic Autoimmune Disease and Chronic Inflammatory Rheumatism, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.

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 4 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: status not confirmed, as of the sponsor's last update on 11 Feb 2021. 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 France. 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?

Results are not available in the source record.

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

Contact Xavier MARIETTE (00 33 1 45 21 37 58, xavier.mariette@aphp.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Characterization of the quantitative and qualitative specificities of the different leukocyte subpopulations in patients with chronic inflammatory rheumatism and rare systemic autoimmune diseases (time frame: At the end of the study (5 years)). 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 11 Feb 2021.
