ABSTRACT
INTRODUCTION: Atopic dermatitis (AD) is a chronic immuno-inflammatory skin disease. Crisaborole ointment, 2%, is a nonsteroidal phosphodiesterase 4 inhibitor approved for the treatment of mild to moderate AD. This post hoc analysis assesses the efficacy and safety of crisaborole in Chinese patients aged ≥ 2 years with mild to moderate AD. METHODS: We evaluated the efficacy and safety of crisaborole in Chinese patients from the vehicle-controlled, phase 3 CrisADe CLEAR study. Patients were randomly assigned 2:1 to receive crisaborole or vehicle twice daily, respectively, for 28 days. The primary endpoint was percent change from baseline in Eczema Area and Severity Index (EASI) total score at day 29. Key secondary endpoints were improvement in Investigator's Static Global Assessment (ISGA), ISGA success, and change from baseline in weekly average Peak Pruritus Numerical Rating Scale (PP-NRS) score. Adverse events were documented. RESULTS: Of 391 patients in the overall study, 237 were from China, 157 assigned to crisaborole and 80 assigned to vehicle. A greater reduction in percent change from baseline in EASI total score at day 29 was shown in the crisaborole vs. vehicle group (least squares mean [LSM]: -66.34 [95% (confidence interval) CI -71.55 to -61.12] vs. -50.18 [95% CI -58.02 to -42.34]). Response rates for achievement of ISGA improvement (43.2% [95% CI 35.4-51.1] vs. 33.4% [95% CI 22.5-44.2]) and ISGA success (31.7% [95% CI 24.3-39.0] vs. 21.5% [95% CI 12.1-30.9]) at day 29 were higher in the crisaborole vs. vehicle group. A greater reduction in change from baseline in weekly average PP-NRS score at week 4 was observed in the crisaborole vs. vehicle group (LSM: -1.98 [95% CI -2.34 to -1.62] vs. -1.08 [95% CI -1.63 to -0.53]). No new safety signals were observed. CONCLUSION: Crisaborole was effective and well tolerated in Chinese patients aged ≥ 2 years with mild to moderate AD. TRIAL REGISTRATION: ClinicalTrials.gov, NCT04360187.
ABSTRACT
BACKGROUND: Atopic dermatitis (AD) is a chronic inflammatory skin disease associated with intense and persistent pruritus. OBJECTIVES: To examine associations between AD symptoms and health-related quality of life (HRQoL) in adults (aged ≥18 years) with moderate-to-severe AD. MATERIALS & METHODS: Patient chart and survey data from physicians within Europe were derived from the Adelphi AD Disease Specific Programme (Q3 2019-Q2 2020). HRQoL measures included Euro-Qol 5-dimension, 3-level, questionnaire; Dermatology Life Quality Index; and Work Productivity and Activity Impairment-Atopic Dermatitis questionnaire. Data were evaluated using descriptive statistics and generalized linear models. RESULTS: Of 631 patients, 90.1%, 49.3%, 18.5% and 17.7% reported pruritus, sleep disruption, anxiety and depression, respectively. Adjusted analyses indicated an increased frequency of symptoms associated with worse HRQoL and greater work/activity impairments, particularly for patients with pruritus and sleep disruption. CONCLUSION: Reductions in symptom frequency may have important implications for improving the overall health of patients with moderate-to-severe AD.
