Abstract

INTRODUCTION: Skin pain (described as discomfort or soreness) is increasingly recognized as a symptom of atopic dermatitis which impacts patient quality of life. This analysis examined the effect of baricitinib on skin pain in atopic dermatitis in three phase 3 studies (BREEZE-AD1, -AD2, and -AD7).

METHODS: Patients were randomly assigned 2:1:1:1 to receive once-daily placebo, baricitinib 1 mg, 2 mg, or 4 mg in BREEZE-AD1 (N = 624) and -AD2 (N = 615) and 1:1:1 to receive once-daily placebo, baricitinib 2 mg, or 4 mg, with topical corticosteroids, in BREEZE-AD7 (N = 329) for 16 weeks. Patients recorded their skin pain severity using the Skin Pain Numerical Rating Scale (NRS) via an electronic daily diary. Data were analyzed by study as least squares mean change from baseline in daily scores for the randomly assigned patients using mixed model repeated measures analysis. Analysis of Skin Pain NRS response was done using logistic regression using non-responder imputation.

RESULTS: Baricitinib produced significant percentage change from baseline compared with placebo in patient-reported skin pain severity by day 2 in BREEZE-AD1 (baricitinib 4 mg - 11.9%, p < 0.001; baricitinib 2 mg - 6.4%, p = 0.016; baricitinib 1 mg - 6.2%, p = 0.016), -AD2 (baricitinib 4 mg - 12.6%, p < 0.001; baricitinib 2 mg - 5.6%, p = 0.036; baricitinib 1 mg - 6.9%, p = 0.011), and -AD7 (baricitinib 4 mg - 6.9%, p = 0.04; baricitinib 2 mg - 7.9%, p = 0.018). A greater proportion of patients treated with baricitinib reported at least a 4-point reduction in Skin Pain NRS score at week 16 (Skin Pain NRS responders) in BREEZE-AD1 (baricitinib 4 mg 25.3%, p < 0.001), -AD2 (baricitinib 4 mg 20.0%, p < 0.001; baricitinib 2 mg 19.0%, p < 0.001), and -AD7 (baricitinib 4 mg 48.8%, p < 0.001; baricitinib 2 mg 45.2%, p = 0.004) compared to placebo. A significantly higher proportion of Skin Pain NRS responders also achieved at least a 4-point improvement in Dermatology Life Quality Index at week 16 when compared with Skin Pain NRS non-responders in BREEZE-AD1 (89.2%, p < 0.0001), -AD2 (92.5%, p < 0.0001), and -AD7 (88.3%, p < 0.0001).

CONCLUSION: Baricitinib improved patient-reported skin pain severity as early as day 2. CLINICALTRIALS.
