What it measures

1. Percentage of subjects with Alopecia Severity Score Tool (SALT) score < or = 20%

   Time frame: Week 24

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: this record registers a primary completion to the day, so a day is what is shown. Where a sponsor registers only a month, only a month is shown.

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.
