We explored patient satisfaction with baricitinib, an oral Janus kinase inhibitor, in patients with atopic dermatitis (AD) treated in routine clinical practice. Adults with moderate-to-severe AD treated with baricitinib in clinical practice for ≥4 weeks in France, Germany, and the UK completed a one-time online survey under market research methodologies. Treatment satisfaction was assessed using a Likert scale and abbreviated Treatment Satisfaction Questionnaire for Medication (TSQM-9). Patients reported demographic, disease, and treatment information. Data were analyzed descriptively. The survey was completed by 170 patients with a mean age of 39.3 years (SD = 13.5), 59% (n = 101) were female. At baricitinib initiation, 79% rated their AD as "Severe", yet 28% reported body surface area (BSA) involvement ≥10%. Most were "Satisfied" or "Very satisfied" (76%/18%) with baricitinib, with high rates reported for controlling itch (36%/56%). Itch improvements were noted by 97% of patients. Some tapered/stopped (50%/32%) topical corticosteroid use, aligned with reported improvements on the patient global assessment and BSA. Mean TSQM-9 convenience score was 78.0 (SD = 14.0). Satisfaction with itch control was particularly high, reflected in rates of improvement in itch since starting baricitinib. On the TSQM-9, the convenience score was the highest. Many patients tapered/stopped concomitant topicals, indicating baricitinib's effect in controlling AD symptoms. [ABSTRACT FROM AUTHOR]

Baricitinib is an oral selective Janus kinase 1/2 inhibitor approved for moderate-to-severe atopic dermatitis (AD) in adults. To evaluate absolute Eczema Area and Severity Index (EASI) and SCORing of Atopic Dermatitis (SCORAD) outcomes over 16 weeks and to link disease severity categories to quality of life (QoL) improvements. This post-hoc analysis included patients enrolled in Phase3 monotherapy (BREEZE-AD1/AD2) and topical corticosteroid (TCS) combination therapy (BREEZE-AD7) trials and analyzed baricitinib 2 and 4 mg vs. placebo. Categorical outcomes were analyzed using Fisher's exact test. Significantly more baricitinib-treated patients reached EASI ≤ 7 and SCORAD < 25 as early as week 1 in monotherapy and week 2 in TCS combination therapy, compared to placebo. Significant response vs. placebo was sustained until week 16 for EASI ≤ 7 (AD1/2 [p-value vs. placebo]: 2 mg = 19.9%, 4 mg = 25.4% [p = 0.001] and AD7: 2 mg = 40.4% [p = 0.087], 4 mg = 48.6% [p = 0.003]) and SCORAD < 25 (AD1/2: 2 mg = 12.2%, 4 mg = 19.4% [p = 0.001] and AD7: 2 mg = 30.3% [p = 0.025], 4 mg = 34.2% [p = 0.004]) severity categories. These effects were accompanied by rapid improvements in QoL. Baricitinib-treated patients rapidly achieved recommended absolute EASI and SCORAD treatment outcomes which were sustained until week 16. Improvements in QoL were greater than EASI severity categories reflected, indicating that physician-assessed scores do not necessarily correlate with patients' impression of AD severity.

Insights into the real-world treatment paradigm and long-term burden of atopic dermatitis (AD) are needed to inform clinical and health policy decisions. The prospective, observational EUROSTAD study enrolled adults with moderate-to-severe AD starting or switching systemic therapy (51 sites in 10 European countries). We report the baseline characteristics, treatment patterns, and outcomes of these patients using descriptive statistics. A 12-month enrollment period of EUROSTAD was completed and 308 patients were enrolled: average age 37 years, AD duration 25 years, 43% were female. Most patients reported use of systemic therapy (93%) and ≥1 atopic comorbidity (82%). Mean [standard deviation] disease severity/burden measures were high: Investigator's Global Assessment (3.1 [0.8]), Eczema Area and Severity Index (16.2 [10.9]), Peak Pruritus Numerical Rating Scale (5.5 [2.5]), sleep impairment Visual Analog Scale (49.8 [31.6]) scores, and time lost from work (4.1 [13.7] days/year) or usual activities (16.8 [38.7] days/year). Most patients showed borderline or clinical levels of anxiety (59%) and/or depression (63%) using the Hospital Anxiety and Depression Scale. Adults with moderate-to-severe AD starting/switching systemic treatment enrolled in EUROSTAD have a high burden of longstanding disease despite continuous use of topical drugs, emollients, and systemic therapies.
