About this study

The aim of this open, controlled, multicentre biomedical research study is to identify new markers specifically associated with Horton's disease. This would make it possible to improve the diagnosis and management of this disease.

Participation consists in taking one or several blood samples depending on the group patients/controls.

Being tested
1 blood sample, 2 to 3 blood samples (at inclusion, at 3 months and at 6 months in cases of relapse)
Medical subject headings
Giant Cell Arteritis, Communicable Diseases, Neoplasms

What is being measured

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

  1. Quantification of specific cytokines of the Th17 immune response (IL-17 A and IL-23) in the serum

    Measured: Up to 6 months

  2. Quantification of LTh17 by flow cytometry

    Measured: Up to 6 months

  3. Measurement of the activation level of genes specifically involved in Th17 response using RT-PCR on frozen mRNA

    Measured: Up to 6 months

  4. Measure the ability of Treg to proliferate and to synthesize IL-17 in response to different antigenic stimulations

    Measured: Up to 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Horton's Disease and Infectious Disease, run by Centre Hospitalier Universitaire Dijon at 3 sites 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 24 inclusion and 1 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 6 May 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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?

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?

Quantification of specific cytokines of the Th17 immune response (IL-17 A and IL-23) in the serum (time frame: Up to 6 months). The study lists 4 primary outcomes in all. 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 6 May 2019.
