Scientific titleExcimer laser versus clobetasone propionate in prurigo form of atopic dermatitis
Study objectivesAs Narrow Band UltraViolet B (NB-UVB) is known to be effective in Atopic Dermatitis (AD), the excimer laser appears to be a promising treatment for localised AD. We designed a randomised single blind within-patient controlled trial to investigate the efficacy of the excimer laser versus routine topical corticosteroid, clobetason propionate.
Ethics approval(s)Approval recieved from the Medical Ethical Committee (Medisch Ethische Commissie) on the 19th October 2006 (ref: MEC 06/239).
Health condition(s) or problem(s) studiedAtopic dermatitis
InterventionAll patients will be randomised to a within-patient left-right comparison study of excimer laser versus topical clobetason propionate. Treatment with the ecximer laser will be performed twice a week, during a treatment period of ten weeks. Clobetason propionate will be applied by the patients themselves once a day , according standardised instructions, during a treartment period of ten weeks.
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Specified
Drug / device / biological / vaccine name(s)Clobetasol propionate
Primary outcome measureClinical responses will be evaluated using physician assessment of individual signs (number of nodules, elevation of nodules, excoriation, erythema and pruritus).
Secondary outcome measures1. Photographic documentation
2. Physician Global Assessment (PGA)
3. Patient Global Assessment (PaGA)
4. Besides the clinical responses, the patient and physician satisfaction/preference and duration of remission will be evaluated.
