The Role of Gut and Skin Microbiota in Alopecia Areata

The registered record

Accession number

NCT07705217

Registered condition naming hair loss

Alopecia Areata

Fecal Microbiota Transplantation (FMT)T Cell SubsetsMicrobiome

The first row holds the registered condition that placed this trial on the pipeline; the second holds everything else the sponsor registered on the same record. Both are shown, and shown apart rather than shaded differently, because leaving the second out would make this trial look more like a hair-loss study than its registration says it is — and because a distinction carried only by colour is not a distinction for every reader.

What it measures

1. Changes in hair growth- Severity of Alopecia Tool

   Time frame: From enrollment to the end of treatment at 48 weeks

2. Changes in hair growth- Alopecia Areata Investigator Global Assessment

   Time frame: From enrollment to the end of treatment at 48 weeks

3. Changes in hair growth- The Alopecia Areata Scale

   Time frame: From enrollment to the end of treatment at 48 weeks

4. Fecal microbiota transplantation modulation of the gut and skin microbiota

   Time frame: From enrollment to the end of treatment at 48 weeks

5. Change in T cell subsets from Baseline to 48 weeks

   Time frame: From enrollment to the end of treatment at 48 weeks

Primary outcome measures only, as registered. What a trial chose to measure, and when, is the most informative thing about it that is knowable before it reports — a hair-count endpoint at 24 weeks and a patient-satisfaction endpoint at 12 weeks are not the same study.

"Estimated" and "actual" are the registry's own labels: an estimated date is a plan, and plans move. A date is printed at the precision it was registered at: a primary completion registered as 2027-02 is a month, and rendering it as 1 February 2027 would invent a day the sponsor did not register.

Results

This trial has not reported results. ClinicalTrials.gov holds no results record for it. That is the ordinary state of a trial that is running or about to run, and it means there is nothing here to tell you about whether the intervention works — including nothing negative. If this page implied otherwise it would be wrong.
