About this study

Official title: Study of the Role of Innate Lymphoid Cells and Natural Killer Cells in Immune Activation of Vitiligo

The cohort included only major patients with non-segmental vitiligo and no other autoimmune or inflammatory associated diseases (except thyroiditis). Control subjects should have no autoimmune or inflammatory diseases. Patients and controls should not take treatment with corticosteroids or other potentially immunomodulatory therapies. Patients and controls are recruited in the Dermatology Department of the University Hospital of Nice and the Hospital of Fréjus. The investigators have already initiated the collection of tissues and blood from patients and control subjects and we have succeeded in isolating ILCs and NKs from a blood volume of 50ml. We were able to sort the ILC subpopulations. Early data suggest an increase in Natural Killer (NK) and Innate Lymphoïdes Cells 1 (ILC1) in the blood of vitiligo patients compared to control subjects. The investigators also managed to extract the melanocytes from the skin biopsies of the first patients and control subjects.

The investigators want study the presence and type of ILC and NK in the blood and skin of vitiligo patients compared to control subjects.

Questions about this trial

What is this clinical trial studying?

An observational study of Vitiligo, run by Centre Hospitalier Universitaire de Nice 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 5 inclusion and 0 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 9 Dec 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 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?

study the presence and type of ILC and NK in the blood and skin (time frame: 1 day). The study lists 2 primary outcomes in all. 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 NCT03859518, which also lists 12 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 9 Dec 2019.
