About this study

Official title: Collection d'échantillons Biologiques Humains de Sujets Sains et Malades Pour la Mise au Point et la Validation de Nouvelles méthodes de Diagnostic et Pour la réalisation d'Expertises Dans le Domaine Des Maladies Infectieuses et Tropicales

Read the detailed description

Direct constitution of collection from various samples taken on a prospective cohort of healthy volunteers, to prepare human biological samples of known characteristics (biochemical and serological in particular) and quality controlled.

This collection will allow, as a priority, a development stage, ie the establishment of the proof of concept of new diagnostic methods in the field of infectious and tropical diseases.

There will be 2 cohorts (= arms) for this study: the main cohort of healthy volunteers and the N cohort, which will consist of patients with neuro-meningeal disease of infectious appearance and followed in specialized consultation.

Conditions: Infectious Disease, Tropical Disease
Being tested: biological samples, lumbar puncture
Keywords: sample, diagnostic
Medical subject headings: Communicable Diseases, Disease

What participants receive

Study group	Role	What they receive
Healthy volunteers	Experimental	Human biological samples: whole blood (serum or plasma, PBMCs, red blood cells), urine, feces, saliva, tears, mouth and skin swabs. Bio-clinical data : adjusted to the purpose of the searches will be collected Receives: Biological: biological samples

What is being measured

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

development of new diagnostic methods
This collection will allow, as a priority, a first stage of development, that is to say the completion of the proof of concept of new diagnostic methods in the field of infectious and tropical diseases.
Measured: during all the study

Secondary outcomes (1)

performance improvement
In a second step, the collection will be able to improve the essential performances (sensitivity and specificity) of the methods to the study compared to the existing methods: speed, simplicity (molecular methods, etc) and cost; and may also uncover new non-infectious biomarkers.
Measured: during all the study

Questions about this trial

What is this clinical trial studying?

A study testing biological samples and lumbar puncture in people with Infectious Disease and Tropical Disease, run by Institut Pasteur at 2 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 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 7 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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.
