Details and patient eligibility

About

The aim of the study is to evaluate the efficacy and safety of a combined approach of cryotherapy and tirbanibulin for the treatment of actinic keratosis of the scalp and forehead, repeated every 4 months. A higher rate of complete response is expected with this combination compared to cryotherapy alone, as well as a better response with repeated treatment cycles.
