Interventions and Outcome Measures

Arms

experimental: 4 months Placebo, then 8 months SADBE 5%

experimental: 12 months SADBE 5%

Interventions

Placebo

Placebo is acetone. At baseline, the investigator will record the area that will be treated in mm2 . Use of a 1 mm x 1 mm gridded transparency will be used to record the treatment area at baseline. At subsequent visits, the study intervention will be applied to the entire treatment area defined at baseline, regardless of any new hair growth. The assigned study intervention is applied monthly by the PI (or designee) to the treatment areas affected by AA on the scalp and/or eyebrows identified at Baseline. The topical solution is applied with a cotton tip applicator by the PI or their qualified designee. Solution is applied by gently pressing a cotton tip applicator that has been soaked in the study solution against the skin. Treatment is repeated monthly.

SADBE 5%

SADBE 5% is a solution of 5% Squaric Acid Dibutyl Ester (SADBE) in acetone. At baseline, the investigator will record the area that will be treated in mm2 . Use of a 1 mm x 1 mm gridded transparency will be used to record the treatment area at baseline. At subsequent visits, the study intervention will be applied to the entire treatment area defined at baseline, regardless of any new hair growth. The assigned study intervention is applied monthly by the PI (or designee) to the treatment areas affected by AA on the scalp and/or eyebrows identified at Baseline. The topical solution is applied with a cotton tip applicator by the PI or their qualified designee. Solution is applied by gently pressing a cotton tip applicator that has been soaked in the study solution against the skin. Treatment is repeated monthly.
