Summary

This trial explores using clascoterone to treat acne in transgender males receiving hormone therapy, as current treatments can interfere with their hormones.

Who is the study for?
This trial is for transgender male patients aged 16 or older with acne that started or got worse after beginning masculinizing hormone therapy (MHT). They must have been on a stable MHT dose for at least 3 months and expect to continue the same dose. Participants need at least 20 papules or pustules and should maintain their current skin care routine throughout the study.
What is being tested?
The study tests Clascoterone, an FDA-approved cream that blocks androgen receptors, which might help treat acne caused by testosterone in transgender males on hormone therapy. It's compared against a placebo cream (vehicle) to see if it's effective when other treatments are unsuitable due to interference with hormone therapy.
What are the potential side effects?
While specific side effects of Clascoterone in this context aren't detailed, common ones may include skin irritation, redness, itching, or peeling where the cream is applied. These are typical reactions for topical acne treatments.
