BackgroundThe validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD™) is a standardized severity assessment for use in clinical trials and registries for atopic dermatitis (AD).ObjectivesTo investigate the reliability, validity, responsiveness and within-patient meaningful change of the vIGA-AD.MethodsData were analysed from adult patients with moderate-to-severe AD in the BREEZE-AD1 (N = 624 patients; NCT03334396), BREEZE-AD2 (N = 615; NCT03334422) and BREEZE-AD5 (N = 440; NCT03435081) phase III baricitinib clinical studies.ResultsAcross studies, test-retest reliability for stable patients showed moderate-to-good agreement [range of Kappa values for Patient Global Impression of Severity-Atopic Dermatitis (PGI-S-AD), 0·516-0·639; for Eczema Area and Severity Index (EASI), 0·658-0·778]. Moderate-to-large correlations between vIGA-AD and EASI or body surface area (range at baseline, 0·497-0·736; Week 16, 0·716-0·893) supported convergent validity. Known-groups validity was demonstrated vs. EASI and PGI-S-AD (vIGA-AD for severe vs. moderate EASI categories at baseline, P

BackgroundAtopic dermatitis (AD) is a common skin disorder characterized by chronic inflammation, altered skin barrier function, and inflammatory cell skin infiltration that decreases health-related quality of life (HRQoL). The study objective was to understand the patient perspective of AD burden and determine suitable patient-reported outcome (PRO) measures.MethodsThis mixed methods study involved the collection of qualitative and quantitative information from adults (≥ 18 years old) and adolescents (12 - 17 years old) with clinician-confirmed AD regarding their experiences of AD symptoms and its impact on HRQoL. The first part of the study included three stages: in-person concept elicitation (CE) interviews, a 2-week daily electronic diary (eDiary) study, and in-person cognitive debriefing (CD) interviews. An Itch numeric rating scale (NRS) (v1.0) and a Skin Pain NRS (v1.0) evaluation during CD interviews required participants to think about their 'worst' itch and 'worst' skin pain in the past 24 h. Other PRO measures allowed for psychometric testing. The second part of the study involved telephone-depth interviews (TDIs) and qualitative feedback from participants who had not participated in the CD interviews. Qualitative data were thematically analyzed. Psychometric evaluation of NRS measures was performed using eDiary data.ResultsIn the CE interviews, itch and/or itching and skin pain were the most prevalent symptoms consistently discussed by participants. Both NRS measures demonstrated strong psychometric reliability and were applicable across ages with suitable concurrent validity. During the CD interviews, some participants focused their answers on their 'average' itch/itching in the past 24 h, rather than their 'worst' itch. Some participants answered the Skin Pain NRS thinking about general pain or other types of pain, rather than skin pain specifically. Consequently, modifications to both measures addressed these issues and re-tested as paper-and-pen versions in subsequent TDIs. Itch NRS (v2.0) modifications helped participants focus on their worst itching. Most participants preferred Skin Pain NRS v2.0b, which included skin pain descriptors.ConclusionsItching and skin pain are the most important and relevant AD symptoms. The Itch NRS (v2.0) and Skin Pain NRS (v2.0b) appear to be appropriate endpoints for the assessment of itching and skin pain severity for clinical trials with adults and adolescents with AD.

Summary: Background: Baricitinib, an oral selective Janus kinase (JAK)1 and JAK 2 inhibitor, was shown to improve the signs and symptoms of moderate‐to‐severe atopic dermatitis (AD). Objectives: To evaluate the efficacy and safety of baricitinib with background topical corticosteroids (TCS) in patients with moderate‐to‐severe AD and inadequate response, intolerance or contraindication to ciclosporin A (CA). Methods: In this double‐blind, randomized, placebo‐controlled, phase III study, patients were randomized 1: 1: 2: 1 to placebo (N = 93), baricitinib 1 mg (N = 93), 2 mg (N = 185) or 4 mg (N = 92) with background TCS. The primary endpoint was the proportion of patients receiving baricitinib 4 mg or 2 mg (+ TCS) vs. placebo + TCS who achieved ≥ 75% improvement from baseline in the Eczema Area and Severity Index (EASI 75) at week 16. Results: Baricitinib 4 mg + TCS was superior to placebo + TCS for EASI 75 (4 mg: 32%, placebo: 17%, P = 0·031) at week 16 and for improvements in itch, skin pain and number of night‐time awakenings owing to itch. Improvements were maintained through 52 weeks of treatment. Treatment‐emergent adverse events (TEAEs) were more common with baricitinib than placebo (+ TCS); most were mild or moderate. The most frequent TEAEs with baricitinib 4 mg + TCS were nasopharyngitis, herpes simplex, influenza and headache. No deaths or deep vein thromboses were reported. Conclusions: Baricitinib 4 mg + TCS improved the signs and symptoms of moderate‐to‐severe AD through 52 weeks of treatment in patients with inadequate response, intolerance or contraindication to CA. The safety profile was consistent with previous studies of baricitinib in moderate‐to‐severe AD. What is already known about this topic?Ciclosporin A is indicated for the treatment of atopic dermatitis that is refractory to topical therapies. However, its use is limited by safety concerns and it may not provide adequate response for some patients.Baricitinib, an oral selective Janus kinase (JAK)1 and JAK2 inhibitor, has been shown to improve the signs and symptoms of moderate‐to‐severe atopic dermatitis as a monotherapy or in combination with topical corticosteroids. What does this study add?Baricitinib combined with background low‐ or moderate‐potency topical corticosteroids provided improvements in the signs and symptoms of moderate‐to‐severe atopic dermatitis through 1 year of treatment in patients with a contraindication, intolerance or failure to respond to ciclosporin A.The most common treatment‐emergent adverse events with baricitinib 4 mg were nasopharyngitis, herpes simplex, influenza and headache.The safety profile was consistent with previous studies in patients with moderate‐to‐severe atopic dermatitis.

Baricitinib previously demonstrated improvements in itch and sleep disturbance versus placebo in adults with moderate-to-severe atopic dermatitis (AD). Examine if itch and sleep improvements are associated with better quality of life (QoL) and productivity in patients with AD. Data were drawn from BREEZE-AD5 (NCT03435081). Itch and sleep improvement at Week 16 were defined using ≥4-point improvements in the Itch Numeric Rating Scale and ≥1.5 decreases in the number of nighttime awakenings since baseline, respectively. Patients with and without improvements were compared on Dermatology Life Quality Index (DLQI) and Work Productivity and Activity Impairment-AD scores. Changes from baseline were analyzed using ANCOVA with last observation carried forward. Proportions were analyzed using logistic regression with non-responder imputation. Greater proportions of patients with versus without itch improvement indicated no impact of AD on QoL (37.7 vs. 1.8%). Patients with itch improvement had greater decreases in work time impaired (−29.3 vs. −5.6%). More patients with versus without sleep improvement reported no effect of AD on QoL (25.5 vs. 1.1%); patients with better sleep experienced larger reductions in work time spent impaired (−33.3 vs. −6.1%). Patients with AD who experienced itch and sleep improvement had significantly better QoL and productivity. [ABSTRACT FROM AUTHOR]

Background: Initiation and titration of human regular U-500 insulin (U-500R) with a dosing algorithm of either thrice daily (TID) or twice daily (BID) improved glycemic control with fewer injections in patients with type 2 diabetes treated with high-dose, high-volume U-100 insulin. The objective of this analysis was to compare patient-reported outcomes between U-500R TID and BID treatment groups in this titration-to-target randomized, clinical trial. Methods: In this 24-week, open-label, parallel trial, 325 patients were randomized to TID (n = 162) or BID (n = 163) U-500R after a 4-week lead-in period (screening). The Treatment Related Impact Measure-Diabetes (TRIM-D) and EQ-5D-5L questionnaires were administered at screening, baseline/randomization, and endpoint (24 weeks). The Visual Analog Scale-Injection Site Pain (VAS-ISP) was assessed at baseline/randomization, 12 weeks, and endpoint. Results: The TRIM-D showed statistically significant improvements in overall scores from baseline to endpoint for both BID and TID groups, most domains in the TID group, and all domains in the BID group. The BID group achieved better scores than the TID patients in overall and in treatment burden, daily life, and compliance domains (p < .05). EQ-5D-5L index scores showed no statistically significant differences for TID and BID groups (and no differences between TID and BID groups) from baseline to endpoint. VAS-ISP scores improved for both treatment groups (-5.60 TID; -6.47 BID; p < .05 for both) from baseline to endpoint. Conclusions: U500 can be successfully titrated for improved glycemic control using BID and TID regimens with diabetes-specific Patient-Reported Outcomes showing improvements in both arms; however, BID had better scores than TID in overall, treatment burden, daily life, and compliance domains.

Background: Baricitinib, an oral selective inhibitor of Janus kinase 1 and Janus kinase 2, modulates proinflammatory cytokine signaling.Objectives: The efficacy and safety of baricitinib were evaluated in patients with moderate-to-severe atopic dermatitis (AD).Methods: In this phase 2, randomized, double-blind, placebo-controlled study, 124 patients with moderate-to-severe AD applied topical corticosteroids (TCSs) for 4 weeks before randomization to once-daily placebo, 2 mg of baricitinib, or 4 mg of baricitinib for 16 weeks. Use of TCSs was permitted during the study. The primary outcome was the proportion of patients achieving at least a 50% reduction in the Eczema Area and Severity Index (EASI-50) compared with placebo.Results: Significantly more patients who received baricitinib, 4 mg, achieved EASI-50 than did patients receiving placebo (61% vs 37% [P = .027]) at 16 weeks. The difference between the proportion of patients receiving baricitinib, 2 or 4 mg, who achieved EASI-50 and the proportion of patients receiving placebo and achieving EASI-50 was significant as early as week 4. Baricitinib also improved pruritus and sleep loss. Treatment-emergent adverse events were reported in 24 of the patients receiving placebo (49%), 17 of those receiving 2 mg of baricitinib (46%), and 27 of those receiving 4 mg of baricitinib (71%).Limitations: A TCS standardization period before randomization reduced disease severity, limiting the ability to compare results with those of baricitinib monotherapy. Longer studies are required to confirm baricitinib's efficacy and safety in patients with AD.Conclusions: Baricitinib used with TCSs reduced inflammation and pruritus in patients with moderate-to-severe AD.

Background: Atopic dermatitis (AD) has a negative impact on patients&rsquo; quality of life (QoL)., Objective: To report the impact of specific AD lesion locations on QoL in adult patients with AD using real-world data., Methods: The Adelphi US Disease Specific Programme was conducted between January&ndash;April 2018. Physicians documented patient demographics/characteristics, AD lesion locations, and body surface area; patients completed questionnaires reporting the impact of lesion locations on QoL., Results: AD severity was moderate in 51.6% of patients and severe in 6.0%. Lesions were commonly identified in more than one location. All AD lesion locations impacted QoL. Visible areas were most bothersome, including head/neck (68%), hands/fingers (58%), front (30%), upper extremities (22%), and lower extremities (16%), with statistically significant associations for a number of Dermatology Life Quality Index (DLQI) items. Itch, soreness, pain, and stinging are also associated with a number of body areas but in particular with those that are most visible/accessible. Lesions on the head/neck and hands/fingers (58%) demonstrated an increased impact on the anxiety and depression dimension of the EuroQol 5-Dimension tool., Conclusions: In patients with AD, quality of life was most affected in patients with lesions in visible areas, including head/neck, hands/fingers, and upper extremities, with statistically significant associations for a number of DLQI domains. Physicians should be aware of the burden of AD lesions on QoL and consider having conversations with patients to better understand the impact of these lesions.

Skin pain is increasingly recognized as an impactful symptom in atopic dermatitis (AD) because of its association with patient discomfort, disease burden, and reduced quality of life. Although the nature of skin pain in AD has not been systematically studied and is therefore not well understood, patients report soreness, discomfort, and tenderness that may reflect peripheral and central pain sensitization. The high prevalence of skin pain suggests that it is not adequately addressed by current therapies for AD and may be undertreated compared with other symptoms. This review discusses the clinical relevance of skin pain with respect to its experience, pathophysiology, relationship with itch, and treatment implications. Recent studies suggest that skin pain presents as a neuropathic symptom independent from itch and the &ldquo;itch-scratch cycle&rdquo;, and poses a unique burden to patients. Recognition of the significant consequences of skin pain and discomfort should reinforce the need to assess and treat this symptom in patients with moderate-to-severe AD.
