The Multidimensional Burden of Atopic Dermatitis Among Adults: Results From a Large National Survey

Single-cell analysis of CD4+ tissue residency memory cells (TRMs) in adult atopic dermatitis: A new potential mechanism

The pathophysiology of atopic dermatitis (AD) is complex. CD4+ T cells play an essential role in the development of lesions in AD. However, the underlying mechanism remains unclear. In the present study, we investigated the differentially expressed genes (DEGs) between adult AD lesioned and non-lesioned skin using two datasets from the Gene Expression Omnibus (GEO) database. 62 DEGs were shown to be related to cytokine response. Compared to non-lesioned skin, lesioned skin showed immune infiltration with increased numbers of activated natural killer (NK) cells and CD4+ T memory cells (p < 0.01). We then identified 13 hub genes with a strong association with CD4+ T cells using weighted correlation network analysis. Single-cell analysis of AD detected a novel CD4+ T subcluster, CD4+ tissue residency memory cells (TRMs), which were verified through immunohistochemistry (IHC) to be increased in the dermal area of AD. The significant relationship between CD4+ TRM and AD was assessed through further analyses. FOXO1 and SBNO2, two of the 13 hub genes, were characteristically expressed in the CD4+ TRM, but down-regulated in IFN-γ/TNF-α-induced HaCaT cells, as shown using quantitative polymerase chain reaction (qPCR). Moreover, SBNO2 expression was associated with increased Th1 infiltration in AD (p < 0.05). In addition, genes filtered using Mendelian randomization were positively correlated with CD4+ TRM and were highly expressed in IFN-γ/TNF-α-induced HaCaT cells, as determined using qPCR and western blotting. Collectively, our results revealed that the newly identified CD4+ TRM may be involved in the pathogenesis of adult AD.

Towards a patient-centred definition for atopic dermatitis flare: a qualitative study of adults with atopic dermatitis

BACKGROUND

The term 'flare' is used across multiple diseases, including atopic dermatitis (AD), to describe increased disease activity. While several definitions of an AD flare have been proposed, no single definition of AD flare is widely accepted and it is unclear what the term 'AD flare' means from the patient perspective.

OBJECTIVES

To understand AD flares from the adult patient perspective and to explore how adults with AD define an AD flare.

METHODS

Participants were adults with AD recruited from the National Eczema Association Ambassadors programme, a volunteer patient-engagement programme. They participated in online focus groups to discuss how they describe AD flares from their perspective, how they define its start and stop, and how they relate to existing definitions of flare. Using a grounded theory approach, transcripts were analysed and coded using an iterative process to identify concepts to support a patient-centred conceptual framework of 'flare'.

RESULTS

Six 90-min focus groups of 3-8 participants each were conducted with 29 US adults (≥ 18 years of age) with AD who had at least one self-reported AD flare in the past year. When participants were presented with examples of previously published definitions of AD flare, participants found them problematic and unrelatable. Specifically, they felt that flare is hard to quantify or put on a numerical scale, definitions cannot solely be about skin symptoms and clinical verbiage does not resonate with patients' lived experiences. Concepts identified by patients as important to a definition of flare were changes from patient's baseline/patient's normal, mental/emotional/social consequences, physical changes in skin, attention needed/all-consuming focus, itch-scratch-burn cycle and control/loss of control/quality of life. Figuring out the trigger that initiated a flare was an underlying concept of the experience of flare but was not considered a contributor to the definition.

CONCLUSIONS

The results highlight the complexity and diversity of AD flare experiences from the adult patient perspective. Previously published definitions of AD flares did not resonate with patients, suggesting a need for a patient-centred flare definition to support care conversations and AD management.

Evaluating Access to Prescription Medications in the Atopic Dermatitis Patient Population in the USA

INTRODUCTION

Despite advances in atopic dermatitis (AD) treatments, many patients face challenges obtaining medications. This study aimed to determine the frequency and causes of insurance coverage delays and denials for AD prescriptions and characterize the associated wait times and extent to which patients understand what to do when faced with a coverage issue.

METHODS

This was a cross-sectional, observational study in which adult U.S. residents (aged 18+ years) with AD or caregivers of pediatric U.S. patients with AD (aged 0-17 years) completed an online survey (3 June-16 July 2021).

RESULTS

Respondents (N = 978) were primarily adults with AD (81.8%), female (67.7%), and white (70.2%). There were 645 insurance delays or denials for AD prescriptions, with 48.1% (470/978) of respondents experiencing at least one delay/denial in the past year. Most delays/denials were for topical steroids (39.2%, 253/645), the most highly used prescription treatment class (83.9%, 821/978). However, the highest rate of delay/denials was for biologics, of which 43.6% (109/250) of all prescriptions faced a delay or denial. Denials were caused primarily by step therapy (27.6%) and delays by prior authorization (55.1%). Only 56.0% of respondents said they would know what to do if they faced an issue with AD prescription coverage.

CONCLUSIONS

Patients with AD frequently experience insurance-related barriers to obtaining recommended therapies, and many do not know how to respond when these barriers arise. Strategies to improve timely therapeutic access are needed.

A Multidisciplinary Approach Is Beneficial in Atopic Dermatitis

Atopic dermatitis (AD) is a highly heterogeneous chronic inflammatory skin disorder that is frequently associated with a plethora of comorbidities. AD is, therefore, considered a systemic disease impacted by a considerable burden and leading to poor quality of life, especially in patients with moderate-to-severe disease. Since atopic and non-atopic comorbidities can further worsen the disease course, accurate establishment of the patient's individual intrinsic risk profile and needs is crucial and may help in guiding the selection of the best treatment option. Better quality of care for patients with AD can be delivered through a multidisciplinary team led by a dermatologist, for comprehensive patient management. The implementation of a multidisciplinary approach for AD could enhance the delivery of optimised and safe treatments, improve the standard of care and patient outcomes in the short and long term, and prevent or delay the lifelong impact of uncontrolled AD. Understanding the unmet needs, assessing correctly the patient risk profile and enhancing the shared patient-physician decision-making process can lead to disease control and quality-of-life improvement, especially in the context of the introduction of newer treatment for AD. This narrative review is a call for more data to establish standardised patient profiles and multidisciplinary strategies in AD management. In view on the fast-evolving treatments for AD, this review aims at highlighting the importance of a multidisciplinary approach to a comprehensive assessment and holistic care in patients with moderate-to-severe AD.

Treatment satisfaction in adults with atopic dermatitis: a cross-sectional, population-based study examining patient and physician perspectives in the US

Studies examining the real-world treatment satisfaction in adults with atopic dermatitis (AD) and the physicians who treat adults with AD are scarce. We sought to characterize treatment satisfaction of adults with AD and physicians' perceived patient satisfaction with AD treatment. We performed a cross-sectional study of adults > = 18 years of age (modified AD UK Working Party Criteria, age onset < = 18 [N = 767]) with AD and a parallel-physician survey among allergists/immunologists [N = 148], dermatologists [N = 149] and primary care medicine [N = 104]. Logistic regression models were used to examine factors associated with patient treatment satisfaction (PTS) or physician-perceived patient treatment satisfaction (pPTS). Factors associated with increased PTS included female, older age, and receiving a written eczema action plan (EAP). Severe AD, itch, pain, and insomnia, greater impact on partner relationships, feeling not adequately informed about AD causes, and being separated, never married, or living with a partner was associated with less PTS. From the physician's perspective, mild AD and development of EAP was associated with increase pPTS, whereas being in practice longer was associated with less pPTS. Limitations include the potential for misclassification of AD and the inability to match AD patients to individual physicians. Recognizing which factors are associated with treatment satisfaction can help inform counseling and decision-making strategies, including the use of an eczema action plan, and support patient-physician outcomes alignment.

Cross-sectional burden-of-illness study in atopic dermatitis (MEASURE-AD) in Australia and New Zealand reveals impacts on well-being

OBJECTIVES

To describe disease burden in individuals with moderate-to-severe atopic dermatitis (AD) in Australia and New Zealand (ANZ) and compare it with other geographic regions.

METHODS

This multicentre, cross-sectional, observational study (MEASURE-AD) recruited consecutive adolescent and adult patients attending dermatology clinics in 28 countries. Data collected included scores of pruritus, disease severity, sleep, pain, disease control, work and quality of life.

RESULTS

This study included 112 ANZ participants (Australia n = 72; New Zealand n = 40) from December 2019 to December 2020. Treatments included topicals (85.7% of patients), non-biologic systemic therapy (28.6%), phototherapy (9.8%) and dupilumab (4.5%). Mean Eczema Area and Severity Index (EASI) score was 22.3 (95% CI 19.6-25.0) and Patient-Oriented Eczema Measurement (POEM) score was 18.4 (95% CI 16.8-20.0). Pruritus Numerical Rating Scale (NRS) was 6.0 (95% CI 5.5-6.6) (50% had severe pruritus) and Dermatology Life Quality Index (DLQI) 14.3 (95% CI 12.8-15.8). ADerm-Impact sleep domain score was 15.1 (95% CI 13.2-16.9). ADerm-Symptom Scale worst skin pain domain score was 5.0 (95% CI 4.3-5.6). Work Productivity and Activity Impairment (WPAI) percentages indicated work and productivity impairment. Inadequately controlled AD was self-reported by 41%, with 9.7 flares in the past 6 months. Scores of pruritus, disease severity, sleep, pain, disease control and quality of life in ANZ were often the highest of all the geographic regions studied.

CONCLUSION

ANZ patients with AD have a high disease burden, which extends across multiple facets of daily life. Many are inadequately controlled with existing therapies.

Targeted Combined Endpoint Improvement in Patient and Disease Domains in Atopic Dermatitis: A Treat-to-Target Analysis of Adults with Moderate-to-Severe Atopic Dermatitis Treated with Upadacitinib

A treat-to-target approach was recently developed to guide systemic treatment for adults with atopic dermatitis (AD). Recommendations outlined criteria for a 3-month initial acceptable treatment target and a 6-month optimal target, evaluated using global assessment of patient-reported disease severity, as well as Eczema Area and Severity Index, itch assessed on an 11-point numerical rating scale, Dermatology Life Quality Index, or Patient-Oriented Eczema Measure. Achievement of these targets with once-daily upadacitinib (15 mg and 30 mg) monotherapy was evaluated using integrated adult data from the Measure Up 1 and 2 phase 3 studies. Among the 852 patients treated with upadacitinib 15 mg or 30 mg, the 3-month initial acceptable target was achieved by >80%, >78%, and ≥87% of patients, and the 6-month optimal target was achieved by ≥53%, >61%, and >73% of patients at weeks 2, 16, and 52, respectively. Achievement of all 6 individual criteria for each of the target goals also increased over time. These findings suggest that upadacitinib 15 mg and 30 mg may help improve standards of care in patients with moderate-to-severe AD by achieving 6-month target goals at 16 weeks and as early as 2 weeks for most patients.

Mendelian Randomization Studies in Atopic Dermatitis: A Systematic Review

Prior studies have found associations between atopic dermatitis (AD) and comorbidities, including depression, obesity, asthma, and allergic rhinitis. Although observational studies often cannot establish robust causality between potential risk factors and AD, Mendelian randomization minimizes confounding when exploring causality by relying on random allelic assortment at birth. In this study, we systematically reviewed 30 Mendelian randomization studies in AD. Body mass index, gut microbial flora, the IL-18 signaling pathway, and gastroesophageal reflux disease were among the causal factors for AD, whereas AD was causal for several medical conditions, including heart failure, rheumatoid arthritis, and conjunctivitis. These insights may improve preventive counseling in AD.

Modelling atopic dermatitis in healthy human skin for the characterization of topical compounds

Suitable human models for the development and characterization of topical compounds for inflammatory skin diseases such as atopic dermatitis are not readily available to date. We describe here the development of a translational model involving healthy human skin mimicking major aspects of AD and its application for the characterization of topical Janus kinase inhibitors. Full thickness human abdominal skin obtained from plastic surgery stimulated in vitro with IL4 and IL13 shows molecular features of AD. This is evidenced by STAT6 phosphorylation assessed by immunohistochemistry and analysis of skin lysates. Broad transcriptome changes assessed by AmpliSeq followed by gene set variation analysis showed a consistent upregulation of gene signatures characterizing AD in this model. Topical application of experimental formulations of compounds targeting the JAK pathway to full thickness skin normalizes the molecular features of AD induced by IL4 and IL13 stimulation. The inhibitory effects of topical JAK inhibitors on molecular features of AD are supported by pharmacokinetic analysis. The model described here is suited for the characterization of topical compounds for AD and has the potential to be extended to other inflammatory skin diseases and pathophysiological pathways.

Early and Sustained Improvements in Symptoms and Quality of Life with Upadacitinib in Adults and Adolescents with Moderate-to-Severe Atopic Dermatitis: 52-Week Results from Two Phase III Randomized Clinical Trials (Measure Up 1 and Measure Up 2)

BACKGROUND

Atopic dermatitis is a chronic inflammatory disease characterized by increased itch, skin pain, poor sleep quality, and other symptoms that negatively affect patient quality of life. Upadacitinib, an oral selective Janus kinase (JAK) inhibitor with greater inhibitory potency for JAK1 than JAK2, JAK3, or tyrosine kinase 2, is approved to treat moderate-to-severe atopic dermatitis.

OBJECTIVE

We aimed to evaluate the effect of upadacitinib on patient-reported outcomes over 52 weeks in adults and adolescents with moderate-to-severe atopic dermatitis.

METHODS

Data from two phase III monotherapy trials of upadacitinib (Measure Up 1, NCT03569293; Measure Up 2, NCT03607422) were integrated. Changes in pruritus, pain, other skin symptoms, sleep, quality of life, mental health, and patient impression were evaluated. Patient-reported outcome assessments included the Worst Pruritus Numerical Rating Scale, Patient-Oriented Eczema Measure, Dermatology Life Quality Index, Atopic Dermatitis Symptom Scale, Atopic Dermatitis Impact Scale, Hospital Anxiety and Depression Scale, SCORing Atopic Dermatitis index, Patient Global Impression of Severity, Patient Global Impression of Change, and Patient Global Impression of Treatment. Minimal clinically important differences, achievement of scores representing minimal disease burden, and the change from baseline were evaluated in patients who received upadacitinib through week 52 and in patients who received placebo through week 16.

RESULTS

This analysis included 1609 patients (upadacitinib 15 mg, N = 557; upadacitinib 30 mg, N = 567; placebo, N = 485). Baseline demographics and disease characteristics were generally similar across all arms. The proportion of patients treated with upadacitinib reporting improvements in itch increased rapidly by week 1, increased steadily through week 8, and was sustained through week 52. Patients receiving upadacitinib also experienced improvements in pain and other skin symptoms by week 1, which continued through week 16; improvements were maintained through week 52. Patient reports of improved sleep increased rapidly from baseline to week 1, increased steadily through week 32, and were sustained through week 52. Patients experienced quality-of-life improvements through week 8, which were maintained through week 52. By week 1, patients in both upadacitinib groups experienced rapid improvements in emotional state, and by week 12, patients also achieved meaningful improvements in anxiety and depression. Improvements in mental health continued steadily through week 32 and were maintained through week 52. Patients treated with upadacitinib 30 mg generally experienced improvements in patient-reported outcomes earlier than those treated with upadacitinib 15 mg. Through week 16, patients receiving upadacitinib experienced greater improvements versus those receiving placebo in all assessed patient-reported outcomes.

CONCLUSIONS

Adults and adolescents with moderate-to-severe atopic dermatitis treated with once-daily upadacitinib 15 or 30 mg experienced early improvements in itch, pain, other skin symptoms, sleep, quality of life, and mental health that were sustained through week 52.

Updates in atopic dermatitis for the primary care physician: A review of advances in the understanding and treatment of atopic dermatitis

Atopic dermatitis (AD) is a common inflammatory skin condition occurring in both pediatric and adult patients. Pruritus is a clinical hallmark of the disease, and patients with AD often experience disruptions to their quality of life. The pathogenesis of AD is a complex and multifactorial interplay between genetic factors, epidermal barrier disruption, and immune dysregulation. Clinically, AD is characterized by pruritus, eczematous skin changes, and age-specific lesion distribution patterns. Infants and young children tend to have AD lesions on their face and extensor surfaces of their extremities while older children and adults tend to have AD lesions on flexural surfaces of their extremities. Many patients also experience a chronic and relapsing disease course. Due to the chronicity and severe pruritus, lesions often undergo secondary changes like lichenification. Patients with AD can experience a number of comorbidities including other atopic disease (i.e. allergic rhinitis, asthma), skin infections, cardiovascular, and neuropsychiatric illnesses. Management of AD depends on the severity of the disease as well as the distribution of the disease. Traditionally, treatment of AD included the use of moisturizers / emollients, topical corticosteroids or topical calcineurin inhibitors, or systemic therapy with non-selective immunosuppressants such as corticosteroids, cyclosporine, azathioprine, or similar. However, in the past decade, new biologic and small molecule drugs, both topical and systemic, have become important therapeutic options for AD patients, especially for those with moderate-to-severe disease. The development of these medications, following decades of research to better understand AD, are designed to specifically target various components of immune dysregulation and inflammation implicated in the pathogenesis of AD. Their successful development and deployment now allow for an exciting new era of treatment for individuals suffering from atopic dermatitis.

Janus kinase inhibitors in atopic dermatitis: an umbrella review of meta-analyses

Background

Clinicians and healthcare policymakers have been drenched with a deluge of overlapping meta-analyses (MAs), and the necessity for comprehensive and clearly defined evidence of Janus kinase inhibitors (JKIs) in atopic dermatitis (AD) is urgent.

Methods

Six databases were searched for MAs published until October 2023. Qualitative description of MAs was mainly used, and Investigator's Global Assessment response (IGA response), the 75% improvement in Eczema Area and Severity Index (the EASI75), peak pruritus Numerical rating score (PP-NRS), and adverse effects were cited to describe the efficacy and safety of JKIs. The methodological quality of the included MAs was assessed by A Measurement Tool to Assess Systematic Reviews II (AMSTAR II), and the quality of evidence was evaluated by the grading of recommendations, assessment, development, and evaluation (GRADE).

Results

Sixteen MAs were pooled in this review, of which five studies appraised JKIs, five appraised systemic JKIs, five papers assessed abrocitinib only, and one assessed baricitinib. Two studies were of "high" methodological quality and 14 MAs were of "moderate" quality. Eleven MAs integrated the results of JKIs and reported that JKIs provide faster onset of IGA response (RR=2.83, 95% CI [2.25, 3.56], high-quality evidence). Similarly, 10 MAs showed that JAK inhibitors were more effective in improving the EASI75 (RR=2.84, 95% CI [2.2, 3.67], high-quality evidence). Results from 12 MAs showed JKIs were active in reducing the PP-NRS (SMD=-0.49, 95% CI [-0.67, -0.32]). All MAs affirmed JKIs added no adverse effects leading to discontinuation and serious adverse events (P<0.05). However, 200mg of abrocitinib had a higher risk of acne (RR=4.34, 95% CI [1.61, 11.71), herpes zoster (RR=1.64, 95% CI [0.42, 6.39]), headache (RR=1.76, 95% CI [1.03, 3]), and nausea (RR=7.81, 95% CI [3.84, 15.87]). Upadacitinib was known to increase acne (RR=6.23, 95% CI [4.08, 9.49]), nasopharyngitis (RR=1.36, 95% CI [1.03, 1.8]) and blood creatine phosphokinase (blood CPK) (RR=2.41, 95% CI [1.47, 3.95]). Baricitinib at 2mg was associated with increased blood CPK (RR=2.25, 95% CI [1.1, 2.97]).

Conclusion

Compared to placebo or dupilumab, the administration of JKIs can ameliorate IGA response more effectively, improve the EASI75, and relieve pruritus without severe adverse effect, while accompanied by more acne, nasopharyngitis, headache, and digestive disturbances. The curative effect of 200 mg of abrocitinib is significant and more caution should be given in patients with gastrointestinal dysfunction, herpes zoster, and those who are acne-prone. Baricitinib and upadacitinib should be avoided in populations at high risk for cardiovascular events.

Development of a Patient Journey Map for Improving Patient Experience and Quality of Atopic Dermatitis Care

INTRODUCTION

Atopic dermatitis (AD) is a chronic inflammatory skin condition that affects both children and adults. AD increases the risk of developing comorbidities like asthma, allergic rhinitis and food allergies. AD patients face difficulties, including itching, lack of effective treatments, lack of funding and discomfort in seeking a diagnosis or treatment. This study aims to identify the main barriers and opportunities to improve the experience of patients with AD and provide high-quality care.

METHODS

Patients, caregivers and healthcare professionals were recruited from the Dermatology Department at Puerta de Hierro Majadahonda University Hospital (Madrid, Spain). Interviews with patients, caregivers and professionals were performed. Participants used storyboards to depict their preferred scenarios for improving healthcare interactions and create a Patient Journey Map.

RESULTS

A total of 15 participants were included in the study. Early symptoms of AD were commonly described as undefined stages. As symptoms worsened, patients and caregivers expressed uncertainty and frustration. Patients became concerned about AD after their first serious flare and started experiencing intense itching, eczema, wounds, shedding or asthma. Topical corticosteroids were used to manage flares, but their effectiveness diminished over time, causing further frustration. Because of the ineffectiveness of their initial treatments, dermatologists observed that patients tended to downplay symptoms and how they affected their quality of life. The specialized treatment of severe AD significantly changed patients' emotional states. Despite AD's chronic nature, patients strived to enjoy remission periods and cope with flares. Psychological and emotional support was crucial for patients and caregivers, a need addressed by the Patients' School initiative at HUPHM hospital.

CONCLUSION

The severity of AD has a profound impact on patients' lives. Patient and caregiver emotional and social needs can be met by adequate communication, access to effective treatments and comprehensive psychological support.

Safety and Efficacy of Upadacitinib for Atopic Dermatitis in Japan: Analysis of the 3-Year Phase 3 Rising Up Study

INTRODUCTION

Upadacitinib is an oral Janus kinase inhibitor approved in multiple countries for moderate-to-severe atopic dermatitis (AD). Here we present long-term data for up to 3 years of continuous upadacitinib treatment in Japanese patients with AD.

METHODS

Rising Up was a phase 3, randomized, multicenter study in Japan investigating the safety and efficacy of upadacitinib in patients with moderate-to-severe AD. Patients aged 12-75 years (weight ≥ 40 kg if < 18 years) were randomized 1:1:1 to receive upadacitinib 15 mg, upadacitinib 30 mg, or placebo through week 16 (all in combination with topical corticosteroids). At week 16, patients who received placebo were rerandomized 1:1 to upadacitinib 15 mg or 30 mg; topical corticosteroids were optional per investigator discretion from weeks 16-160. Safety was assessed by monitoring adverse events (AEs). Efficacy assessments included patients who achieved ≥ 75%/≥ 90% improvement from baseline in Eczema Area and Severity Index (EASI 75/90), clear/almost clear on the validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD 0/1), or a ≥ 4-point improvement from baseline in Worst Pruritus Numerical Rating Scale (WP-NRS).

RESULTS

Of 272 patients enrolled, 230 completed the study. Through week 160, the long-term incidence rate of overall AEs was numerically higher with upadacitinib 30 mg than 15 mg; rates of serious AEs, AEs considered possibly related to study drug, AEs leading to discontinuation, and AEs of special interest were generally low and similar between dose groups. EASI 75, EASI 90, vIGA-AD 0/1, and WP-NRS response rates were generally greater with upadacitinib 30 mg than 15 mg and maintained through week 160 with either dose.

CONCLUSION

For up to 3 years of continuous treatment, upadacitinib was well tolerated in Japanese patients, with a similar safety profile to that of short-term studies and durable long-term response rates for skin clearance and itch improvement.

Burden of Disease in the Real-Life Setting of Patients with Atopic Dermatitis: Italian Data From the MEASURE-AD Study

INTRODUCTION

Atopic dermatitis (AD) is a chronic inflammatory skin disease that negatively impacts the quality of life and work productivity of patients.

OBJECTIVES

We sought to evaluate the real-world burden of AD patients in Italy.

METHODS

This sub-analysis of the MEASURE-AD multicountry study conducted between December 2019-2020 included patients diagnosed with moderate-to-severe AD eligible for or receiving systemic therapy in the previous 6 months. During a single visit, physician and patient-reported questionnaires were used.

RESULTS

A total of 118 adult patients were enrolled and 57.6% (N = 68) of patients had moderate-to-severe AD at the time of enrolment according to the Eczema Area and Severity Index. Sleep disorders interfered with daily function in the previous week in 58.5% (N = 69) of patients, pruritus was severe in 50% (N = 59) and 42.4% (N = 50) reported a flare lasting >7 days in the previous 6 months. According to the Dermatology Quality of Life Index, 37.3% (N = 44) of patients reported a severe impact of AD and approximately 10% had clinical depression/anxiety. Current drug therapy was considered inadequate in controlling AD in 26.3% (N=31) of patients. Work activity impairment was 38.6±31.7% and monthly AD-related expenses were 148.6±134.6 Euros per patient.

CONCLUSIONS

This real-life study documents a high burden of disease in patients with moderate-severe AD in Italy.

Aggregate Response Benefit in Skin Clearance and Itch Reduction With Upadacitinib or Dupilumab in Patients With Moderate-to-Severe Atopic Dermatitis

Background: In patients with moderate-to-severe atopic dermatitis (AD), greater skin clearance and itch reduction are associated with more pronounced improvements in quality of life (QoL). Objective: To characterize the aggregate response benefit with upadacitinib versus dupilumab or placebo in patients with moderate-to-severe AD. Methods: Degree of skin clearance and itch response in 3 phase 3 studies (Heads Up [NCT03738397] and Measure Up 1/2 [integrated; NCT03569293/NCT03607422]) were assessed by the Eczema Area and Severity Index (EASI) and Worst Pruritus Numerical Rating Scale (WP-NRS), respectively, using mutually exclusive categories. The aggregate response benefit with upadacitinib over dupilumab or placebo was determined by summing incremental differences for each EASI or WP-NRS category across the full distribution of patient responses. Results: Comparisons across EASI improvement threshold distributions, EASI severity levels, and WP-NRS categories demonstrated an aggregate response benefit favoring upadacitinib over dupilumab as early as week 4 and continuing at weeks 16 and 24. Similar trends were observed for upadacitinib 15 and 30 mg versus placebo. Conclusions: The aggregate response benefit in skin clearance and itch reduction favored upadacitinib 30 mg over dupilumab and upadacitinib 15 or 30 mg over placebo. These benefits may translate to overall greater improvements in patient QoL.

The role of lebrikizumab in the treatment of atopic dermatitis in the adult population

Although there are many atopic dermatitis (AD) treatments, finding a long-term medication with minimal side effects can be difficult. This review characterizes lebrikizumab as AD treatment in adults. A literature search was conducted to examine lebrikizumab's role in treating moderate to severe AD. In a phase III trial, 74% of adults with AD treated with lebrikizumab 250 mg every 4 weeks achieved an Investigator Global Assessment of 0/1, 79% achieved Eczema Area and Severity Index 75 and 79% experienced improvements in pruritus numeric rating scale scores relative to placebo. Common adverse effects in the ADvocate1 and ADvocate2 trials were conjunctivitis (7 and 8%, respectively), nasopharyngitis (4 and 5%, respectively) and headache (3 and 5%, respectively). Results from clinical trials suggest that lebrikizumab may be a viable alternative for AD management.

Societal costs and health related quality of life in adult atopic dermatitis

BACKGROUND

Cost-of-illness studies are widely used for healthcare decision-making in chronic conditions. Our aim was to assess the cost-of-illness of adult atopic dermatitis (AD) from the societal perspective in Hungary.

METHODS

We conducted a multicentre, cross-sectional questionnaire survey between February 2018 and January 2021. Data was collected from consecutive AD patients aged ≥ 18 years and their physicians at dermatology departments in Hungary. We calculated direct and indirect costs, including costs for treatments, outpatient visits, hospital admissions, informal care, travel costs and productivity loss. To assess indirect costs, the Work Productivity and Activity Impairment (WPAI) questionnaire was used to collect data, and costs were estimated with the human capital approach. Generalized linear model was used to analyse predictors of total, direct and indirect costs.

RESULTS

Altogether 218 patients completed the survey (57.8% female) with an average age of 31.3 (SD = 11.7). Patients' average Dermatology Life Quality Index (DLQI) score was 13.5 (SD = 8.5). According to Eczema Area and Severity Index (EASI) score, 2.3% (n = 5), 21.2% (n = 46), 54.4% (n = 118) and 22.1% (n = 48) had clear, mild, moderate, and severe AD, respectively. We found that the average total, direct medical, direct non-medical and indirect annual costs per patients were €4,331, €1,136, €747, and €2450, respectively, with absenteeism and presenteeism being the main cost drivers, accounting for 24% and 29% of the total cost of AD. A one-year longer disease duration led to, on average, 1.6%, and 4.2% increase in total and direct non-medical costs, respectively. Patients with worse health-related quality of life (higher DLQI score) had significantly higher total, direct medical, direct non-medical costs, and indirect costs.

CONCLUSIONS

Our results indicate a substantial economic burden of AD from a societal perspective, mainly driven by productivity losses.

Safety and Efficacy of Upadacitinib for Atopic Dermatitis in Japan: 2-Year Interim Results from the Phase 3 Rising Up Study

INTRODUCTION

Upadacitinib, an oral, selective Janus kinase inhibitor, is approved in Japan for the treatment of moderate-to-severe atopic dermatitis (AD), a chronic inflammatory skin disease characterized by eczematous morphology and intense itch.

METHODS

Rising Up is an ongoing phase 3, randomized, multicenter study evaluating the long-term safety and efficacy of upadacitinib in Japan. Patients with moderate-to-severe AD were randomized 1:1:1 to topical corticosteroids plus upadacitinib 15 mg (UPA15), upadacitinib 30 mg (UPA30), or placebo at baseline; at week 16, placebo patients were rerandomized 1:1 to UPA15 or UPA30 (plus topical corticosteroids per investigator discretion). This 2-year interim analysis evaluated safety and efficacy through 112 weeks (data cutoff date: 11 August 2021). Adverse events (AEs), AEs of special interest (AESIs), and laboratory data were assessed. Efficacy assessments included ≥ 75% and ≥ 90% improvement from baseline in Eczema Area and Severity Index (EASI 75/90), achievement of clear or almost clear on the validated Investigator Global Assessment for Atopic Dermatitis (vIGA-AD 0/1), and ≥ 4-point improvement in the Worst Pruritus Numerical Rating Scale (WP-NRS).

RESULTS

A total of 272 patients were enrolled and 242 were ongoing at data cutoff (UPA15, n = 120; UPA30, n = 122). After 112 weeks of treatment, serious AEs, AEs leading to discontinuation, and most AESIs were generally infrequent, and rates were similar between the two upadacitinib groups. One event each of rectal cancer and cerebellar hemorrhage was reported in the UPA15 group; no thrombosis events were observed. The most common AEs included acne, nasopharyngitis, and herpes zoster. EASI 75, EASI 90, vIGA-AD 0/1, and WP-NRS response rates were maintained through week 112.

CONCLUSION

UPA15 and UPA30 were well tolerated through 112 weeks of treatment with similar safety profiles to short-term studies and demonstrated durable long-term efficacy for the treatment of moderate-to-severe AD in adults and adolescents.
