What it measures

1. Percentage of subjects achieving an absolute SALT score of 20 or less

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 2028-02 is a month, and rendering it as 1 February 2028 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.
