About this study

Official title: Multi-omics Approaches and Biometrological Analyses to Better Understand Androgenetic Alopecia: Exploratory Study

Androgenetic alopecia is a chronic pathology affecting approximately 50% of men at 50 years old and is characterized by a progressive miniaturization of the hair follicle leading to a localized baldness.

Although it has been shown that testosterone metabolism plays a central role in this pathology, targeting this biological pathway is not fully efficient to treat androgenetic alopecia, suggesting that other factors are involved, notably factors linked to the perifollicular environment. Moreover, the very specific pattern of androgenetic alopecia is not yet fully understood: the occipital and lower temporal areas of the scalp are always preserved. Once the hair follicle has disappeared, it is not possible to make it grow back, it is then important to provide a treatment that slows down the progression of androgenetic alopecia at the earliest stage of the pathology, and that specifically targets the affected area.

The aim of this study is to better understand androgenetic alopecia pathophysiology by a multi-omic approaches and biometrological analysis, in the same study, on the local ecosystem of bald scalp areas and non-bald scalp areas of adult with androgenetic alopecia, compared to scalp of adult without androgenetic alopecia.

Questions about this trial

What is this clinical trial studying?

A study testing Biometrological measurements and Biological sampling in people with Alopecia, Androgenetic and Healthy, run by Pierre Fabre Dermo Cosmetique 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?

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: stopped early, as of the sponsor's last update on 3 Mar 2025. 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 was stopped early (reason given: Lack of recruitment). Results are not available in the source record.

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?

Cutaneous pH measurement (time frame: baseline (Visit 1- Day 1)). The study lists 13 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 3 Mar 2025.
