Therapy for Scabies With Two Differently Concentrated Permethrin Creams

The SKABUP study is a multi-center, prospective, randomized, double-blind phase III clinical trial. The aim of this SKABUP study is to compare the efficacy and safety of topical therapy with permethrin 5% and permethrin 10% in a multicenter randomized double-blind setting in order to demonstrate the possible superiority of the 10% permethrin cream over the current standard therapy with permethrin 5% cream. In order to demonstrate a possible difference in efficacy as clearly as possible, the study will be conducted in dermatology clinics and without extensive exclusion of previous therapies in the patient's medical history.

The primary objective of the SKABUP study is the clincal efficacy (therapeutic success yes/no) after completion of treatment (one or - if necessary - two applications), i.e. treatment success on day 14 (for study participants with only one application of investigational product) or on day 28 (for study participants with repeated application of investigational product).

A total of 220 scabies patients aged between 2 and 85 years are to be included in the study (clinical trial). After 172 patients, however, recruitment will be stopped and an interim evaluation carried out. If there is proof of superiority, the study will be terminated; if there is no proof of superiority, it will be continued unchanged. Study drop-outs, i.e. patients included in the study with at least one application of an investigational product whose participation in the study ends prematurely, will not be replaced.
