简要总结
The purpose of the study is to evaluate the safety and efficacy of once daily use of LEO 80185 topical suspension in adolescent subjects (aged 12 to 17 years) with scalp psoriasis. LEO 80185 topical suspension has marketing approval in many countries under the brand names Taclonex Scalp® Topical Suspension and Xamiol® gel for the treatment of scalp psoriasis in adults. No studies have been performed in subjects younger than 18 years.
