Calcipotriol/betamethasone aerosol foam (Enstilum) for the topical treatment of psoriasis vulgaris in routine practice in Korea: A prospective, noninterventional, multicenter study of treatment outcomes and patient satisfaction

초록

An innovative foam formulation for the fixed-dose combination of calcipotriol and betamethasone dipropionate (Cal/BD) has recently become available for the treatment of psoriasis vulgaris. Observational studies of patients treated with Cal/BD foam in routine practice have been conducted in several Western countries, but there are limited data on outcomes in Asian patients. We performed a prospective, open-label, noncomparative, noninterventional study to investigate treatment outcomes and satisfaction in adult patients receiving Cal/BD foam for psoriasis vulgaris in dermatological centers and outpatient clinics in Korea. Data were collected at the time of enrollment (Visit 1) and at a routine clinic visit similar to 4weeks later (Visit 2). In total, 218 patients were enrolled, of whom 175 were included in the safety analysis set (58.9% male; mean age+ standard deviation 46.7 +/- 15.1 years; use of Cal/BD foam at least once daily 74.3%). Of the safety analysis set, 166 patients had at least mild psoriasis (Investigator Global Assessment [IGA] <= 2) and were analyzed for treatment outcomes and satisfaction. Of the 166 patients, 71.7% had mild psoriasis (IGA 2) at baseline. The majority (57.8%) achieved an IGA of 0/1 (clear/almost clear) at Visit 2. The Psoriasis Area Severity Index (PASI) and Dermatology Life Quality Index (DLQI) showed significant improvements from Visit 1 to Visit 2 (PASI -2.4 +/- 3.0, DLQI -4.5 +/- 5.2, both P <0.0001). Most of the patients were satisfied with the Cal/BD foam treatment; 77.0%, 60.0%, and 73.9% were satisfied in terms of effectiveness, ease of use, and global satisfaction, respectively. In the safety analysis set, adverse events were reported in 13 patients (7.4%). In conclusion, this first Korean real-world study of Cal/BD foam shows improvement of lesions and health-related quality of life after 4weeks of treatment, with high global satisfaction and good overall tolerability and safety.
