Clinico-biological Collection of Autoimmune, Dysimmune or Auto-inflammatory Dermatological Diseases (TekAPo)

March 16, 2026 updated by: University Hospital, Toulouse

Constitution of a Collection of Biological Samples With the Aim of Carrying Out Clinico-biological and Physiopathological Investigations of Autoimmune, Dysimmune or Auto-inflammatory Dermatological Diseases

The aim of this project is to start a biological and clinical collection of patients presenting autoimmune, dysimmune or auto-inflammatory dermatological diseases. This collection will provide appropriate biological samples to identify new biomarkers and to be accessible to the medical, scientific and industrial communities for the identification of new therapeutic strategies.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Autoimmune diseases include around a hundred different clinical entities which are for the most part rare pathologies but which, in combination, concern 5-8% of the adult population with a strong female predominance (FAI²R: the disease chain rare autoimmune and auto-inflammatory drugs, fai2r.org). The common denominator of all these diseases is based on the breakdown of self-tolerance which is the origin of self-reactivity and whose physiopathological mechanisms are still not fully understood, which generates numerous cross-sectional or fundamental studies. In addition to this complexity, there are significant inter-individual variabilities which lead to the definition of subgroups of patients on the basis of the clinical-biological profile and / or the response to treatments. Consequently, and in view of the need to establish the diagnosis early and then to propose the best treatment in the perspective of an individualized medicine, the clinical, biological and genetic characteristics of these subgroups of patients must be explored in order to improve diagnostic and therapeutic capacities.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Building a collection of biological samples and clinical-biological data from patients with autoimmune, dysimmune or auto-inflammatory dermatological disease
Time Frame: Day 0 and through study completion, an average of 1 year
Blood sampling
Day 0 and through study completion, an average of 1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Identification of new autoantibodies
Time Frame: Day 0 and through study completion, an average of 1 year
Western blot or immunoprecipitation method
Day 0 and through study completion, an average of 1 year

Time Frame: Day 0 and through study completion, an average of 1 year
Proteomic analysis of sera and plasma samples at diagnosis and during follow up
Day 0 and through study completion, an average of 1 year
Exploration of the pathophysiological mechanisms of rare autoimmune dermatological pathologies
