Summary
The main objective of the study is to evaluate the efficacy of twice daily applications of delgocitinib cream compared with cream vehicle in the treatment of adult participants with mild to severe lichen sclerosus (LS).

Part 1 of the trial enrolls female participants with LS and results in the selection of the optimal dose for Part 2. The selected dose will then be evaluated in Part 2, which will enroll both female and male participants. Assessment of efficacy and safety of delgocitinib cream in male participants with LS will be evaluated in a substudy. For each participant, the trial will last at least 55 weeks and up to 60 weeks.
