    Recruitment
    Recruitment details
    The subjects were recruited in Denmark, at 2 sites, between 7-Nov-2017 and 22-Mar-2018.

    Pre-assignment
    Screening details
    Main inclusion criteria: clinical unequivocal diagnosis of alopecia areata (AA), maximal duration of current disease episode of 3 years and no ongoing eyebrow hair growth at study start Main exclusion criteria: diffuse type AA, subjects with skin condition(s) or use of treatments which could put subject at risk or interfere with trial assessments

    Blinding implementation details
    The packaging and labelling of the 2 investigational medical products contained no evidence of their identity. There is a slight colour difference between the products. However, the difference is only discernible on close inspection with both products compared side by side. Neither the subject nor the investigator were allowed to see the 2 products at the same time. Subjects from the same household were not allowed to participate.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    07 Feb 2018
    The main reason for this amendment was to revise 2 of the inclusion criteria to reduce the number of screening failures and to aid recruitment into the trial.
    28 Mar 2018
    The main reason for this amendment was to revise 1 of the exclusion criteria to align with the first amendment. The factor 'site' was added to the statistical analysis model. In addition, informed consent date and demographics were added to the data that must be collected for screening failures.

    Interruptions (globally)

    Were there any global interruptions to the trial? Yes
    Date
    Interruption
    Restart date
    16 May 2018
    An unplanned futility analysis was conducted and on the basis of this analysis the trial was terminated prior to completion. For this reason, the trial was reported as an abbreviated report in accordance with ICH E3. Results for 2 secondary efficacy endpoints were therefore neither analysed nor reported.
