Summary:

      The trial was a multicentre, randomised, double-blind, placebo controlled phase 2 trial.

      60 healthy bald male subjects diagnosed with alopecia, who are between 18 and 55 years old
      and provide written informed consent were eligible for inclusion.

      The trial period consisted of a screening period of up to 3 weeks followed by 12 weeks of
      dosing, three times per week. Each subject received two doses of the five trial treatment
      doses (placebo, 0.00625, 0.025, 0.050, and 0.100 μg respectively). The doses were given as
      intradermal injections. On each volunteer, two treatment areas were placed on the head and
      the two selected doses were allocated to the respective treatment areas according to the
      randomisation scheme. The treatment areas were selected on the border between the bald
      surface and the surface with hair.

      The effect on hair growth was measured by the use of Trichoscan imaging and measuring method
      at week 8 and 12. A baseline measaure was taken at day 0.
