Introduction: Standard therapy for patients with mild to moderate atopic dermatitis (AD) typically includes topical therapies; however, patients with more extensive AD and/or AD refractory to topical therapy may benefit from systemic treatment. Ruxolitinib cream monotherapy has demonstrated superior antipruritic and anti-inflammatory effects versus vehicle in patients with mild to moderate AD, and long-term disease control with as-needed use. Here, efficacy/safety of 1.5% ruxolitinib cream through 52 weeks was assessed in a subset of patients with moderate and/or more extensive disease. Methods: This post hoc analysis of TRuE-AD1/TRuE-AD2 included patients who, at baseline, had Investigator's Global Assessment (IGA) score of 3, Eczema Area and Severity Index (EASI) ≥ 16, and affected body surface area (BSA) ≥ 10% (higher severity of disease threshold subgroup). Disease control and safety were assessed. Results: Of 1249 patients in the overall population, 78 (6.2%) met all higher severity of disease threshold criteria (continuous-use vehicle-controlled period: 1.5% ruxolitinib cream, n = 32; vehicle, n = 13); 28 and 4 of these patients, respectively, continued as-needed 1.5% ruxolitinib cream during the long-term safety (LTS) period. At week 8 (continuous-use), IGA-treatment success (IGA 0/1, with ≥ 2-grade improvement from baseline) was achieved by 19/32 (59.4%) patients applying 1.5% ruxolitinib cream versus no patients applying vehicle. In the LTS period, those achieving clear/almost clear skin increased from 19/28 patients (67.9%; continuous-use: week 8) to 18/23 patients (78.3%; as-needed use: week 52) in patients applying ruxolitinib cream from day 1. Ruxolitinib cream was well tolerated, with few application site reactions, regardless of disease severity threshold. Efficacy and safety results were similar to the overall study population. Conclusion: Patients with AD who meet standard disease severity eligibility criteria for systemic therapy may achieve IGA-treatment success with clear/almost clear skin with continuous-use ruxolitinib cream, and maintain long term-disease control with as-needed ruxolitinib cream monotherapy. Trial Registration Number: NCT03745638/NCT03745651. Plain Language Summary: Atopic dermatitis (AD) is a skin condition that causes itchy, dry, and inflamed skin. For many people AD is controlled with medication that is applied to the skin. However, for some people medication that is taken orally or injected (i.e., systemic treatment) may be needed. Systemic treatment can sometimes be challenging. Doctors use a variety of tools to measure AD severity and apply standard criteria to help determine if a person should receive systemic treatment. In the TRuE-AD1/TRuE-AD2 clinical trials, itch and inflammation improved in people with mild to moderate AD after they applied ruxolitinib cream twice daily for 8 weeks. When people then applied ruxolitinib cream to areas of AD only when it was needed for another 44 weeks, ruxolitinib cream provided long-term control of their AD. The aim of this analysis was to assess disease control with ruxolitinib cream in people with AD severe enough to meet the standard criteria indicating a need for systemic treatment. In this group, the majority had clear or almost clear skin after applying ruxolitinib cream twice daily for 8 weeks. After 44 weeks of as-needed application of ruxolitinib cream, most people still had clear or almost clear skin. In this group of people who may have otherwise needed treatment with systemic therapy, ruxolitinib cream twice daily for 8 weeks and then as-needed was generally well tolerated. These results show that as-needed ruxolitinib cream may provide long-term control of AD in people who may otherwise have needed systemic therapy. [ABSTRACT FROM AUTHOR]

Purpose: Ruxolitinib (selective Janus kinase [JAK] 1 and JAK2 inhibitor) cream demonstrated efficacy and safety in patients with atopic dermatitis (AD) in the phase 3 TRuE-AD studies. In TRuE-AD1/ TRuE-AD2 (NCT03745638/NCT03745651), adults and adolescents with mild to moderate AD were randomized to apply twice-daily ruxolitinib cream or vehicle for eightweeks. Here, we evaluated the efficacy and tolerability of ruxolitinib cream by anatomic region, focusing on head/neck (HN) lesions that are typically difficult to manage and disproportionately affect quality of life (QoL). Materials and methods: Eczema Area and Severity Index (EASI) responses in anatomic regions were evaluated in the pooled population (N=1208) and among patients with baseline HN involvement (n=663). Itch, Investigator’s Global Assessment (IGA), QoL, and application site tolerability were also assessed. Results: By Week 2 (earliest assessment), ruxolitinib cream application resulted in significant improvements across all EASI anatomic region subscores and AD signs versus vehicle, with further improvements through Week 8. Significantly more patients with HN involvement who applied ruxolitinib cream versus vehicle achieved clinically meaningful improvements in itch, IGA, and QoL. Application site reactions with ruxolitinib cream were infrequent (<3%), including in patients with HN involvement. Conclusions: These results support the use of ruxolitinib cream for AD treatment across all anatomic regions, including HN. [ABSTRACT FROM AUTHOR]

Introduction: Atopic dermatitis (AD) affects multiple areas of the body, some of which may be more refractory to treatment. We evaluated improvements in the Eczema Area and Severity Index (EASI) by body region and clinical signs for each body region in lebrikizumab-treated patients with moderate-to-severe AD. Methods: ADvocate 1 and ADvocate 2 compared lebrikizumab 250 mg as monotherapy every 2 weeks versus placebo for 16 weeks. Efficacy measures included EASI, which rates the extent and severity of four clinical signs (erythema, edema/papulation, excoriation, lichenification) in four body regions (head/neck, upper extremities, trunk, lower extremities). Analyses are post hoc. Results: Mean baseline EASI, body region EASI subscores, and the severity of clinical signs were consistent across both studies (EASI ranging from 16.0 to 72.0). At week 16 in both studies, patients treated with lebrikizumab showed significantly greater percent improvement in EASI across all body regions versus placebo (p ≤ 0.001), with improvements as early as week 2. In ADvocate 1, all clinical signs significantly improved across all body regions at week 16 with lebrikizumab (51.4–71.6% improvement) versus placebo (23.1–43.5%, p ≤ 0.001), with significant improvements as early as week 2 for all signs. Significant improvements for all clinical signs at week 16 were also seen in ADvocate 2 for lebrikizumab (53.5–75.6%) versus placebo (28.5–41.2%, p ≤ 0.001) and as early as week 2 for all body regions and signs except head/neck erythema and lower extremity erythema, edema/papulation, and lichenification, which showed significant improvement by week 4. Conclusions: Lebrikizumab as monotherapy consistently and rapidly reduced the extent of involvement and severity of AD in all EASI clinical signs and body regions, including the head and neck region and clinical sign of lichenification, compared with placebo. Trial Registration: ClinicalTrials.gov identifier: ADvocate 1 (NCT04146363) and ADvocate 2 (NCT04178967). [ABSTRACT FROM AUTHOR]

Introduction The decision to initiate systemic therapy (ST) in patients with atopic dermatitis (AD) is complex, with no criteria that are globally agreed upon. To aid dermatology providers in this decision-making, the "When to Start Systemic Therapy Checklist" was developed. The checklist comprises three components: (A) clinical severity, (B) subjective burden, and (C) lack of treatment response, each with several criteria. Systemic therapy is indicated when at least one criterion in each component is fulfilled. Objectives To corroborate the validity of this checklist, we evaluated the agreement between the decision to initiate ST using the checklist, against the reference, CorEvitas AD Registry patients prescribed a ST. Methods Adults with moderate-to-severe AD from the prospective, longitudinal CorEvitas AD registry were included in this descriptive analysis (July 2020 – August 2023). Patients were included if they were initiating ST at enrollment (ST group) or not initiating ST at enrollment (non-ST group) but had vIGA-AD® ≥3 and Eczema Area Severity Index ≥12. The checklist criteria were compared against registry outcome measures; when a criterion did not match a measure, either a proxy measure was selected or that part of the questionnaire was excluded. Overall percentage agreement (accord between checklist criteria and ST initiation status [reference standard]) with corresponding 95% confidence intervals (CIs) was calculated. Results In the ST group (n=1488), 97.0% of patients met at least one criterion from section A, 94.1% from section B, and 92.1% for either section A or B. In the non-ST group (n=208), 100% of patients met at least one criterion from section A, 92.3% from section B, and 92.3% from either section A or B. Among patients in the ST group who met at least one criterion each from section A and B, overall percentage agreement was 81.7% (95% CI: 79.8%, 83.5%). Section C, which addresses "lack of treatment response" could not be evaluated due to the absence of relevant data in the registry. Conclusions Nearly all patients initiating ST met at least one criterion from both section A and B of the "When to Start Systemic Therapy Checklist", demonstrating a strong alignment between the checklist sections A and B and disease burden of AD patients in the registry. Subsequent research is needed to assess section C due to registry limitations. Future analyses should examine why some patients with high disease burden and severity remain untreated with systemics.

Therapeutic options for people with moderate or severe atopic dermatitis refractory to topical therapy have rapidly expanded in recent years. These new targeted immunomodulatory agents—biologics and Janus kinase (JAK) inhibitors—have each demonstrated high levels of efficacy and acceptable safety in mostly placebo-controlled clinical trials for atopic dermatitis, but there is no universally applicable algorithm to help choose between them for a given patient. Hence, patients and physicians should utilize shared decision making, discussing efficacy, safety, mode of delivery, monitoring, costs, speed of onset, and other factors to reach individualized treatment decisions. In this review, we try to aid shared decision making by summarizing the efficacy, safety, and monitoring of biologics and oral JAK inhibitors for adults with atopic dermatitis. Network meta-analyses suggest that higher doses of abrocitinib and upadacitinib are more effective than biologics. They also show that, among biologics, dupilumab is likely more effective than tralokinumab and lebrikizumab. Biologics are generally considered safer than JAK inhibitors, although concerns about JAK inhibitors are mainly extrapolated from older generation JAK inhibitors used in higher-risk populations. We also outline evidence and considerations for choosing and using systemic immunomodulatory treatments for special populations including pregnant individuals, those with human immunodeficiency virus (HIV), hepatitis B and C, end stage kidney disease, and older adults.

Background and Objective: Investigator's Global Assessment of clear/almost clear skin (IGA 0/1) is a difficult endpoint to achieve after short-term treatment of chronic moderate-to-severe atopic dermatitis, and does not fully reflect clinically meaningful changes in other parameters. We assessed the impact of tralokinumab versus placebo on other clinically meaningful parameters in patients not achieving IGA 0/1 at week 16 using pooled data from two monotherapy phase III trials, ECZTRA 1 and 2. Methods: This post hoc analysis included patients (n = 1328) from ECZTRA 1 and 2 who did not achieve the co-primary endpoint, IGA 0/1 at week 16 without rescue medication. Endpoints evaluating atopic dermatitis extent and severity included proportions of patients achieving IGA 0/1, 50%, 75%, and 90% improvement in Eczema Area and Severity Index (EASI-50/75/90); endpoints evaluating patient-reported outcomes included a ≥ 3-point improvement in worst daily pruritus Numerical Rating Scale (NRS), a ≥ 3-point improvement in eczema-related sleep interference (sleep) NRS, a ≥ 4-point improvement in Dermatology Life Quality Index (DLQI), and DLQI ≤ 5. Specifically, clinically meaningful responses were defined as EASI-50, a ≥ 3-point improvement in itch NRS, or a ≥ 4-point improvement in DLQI at week 16. Results: Among ECZTRA 1 and 2 patients who did not achieve IGA 0/1 at week 16 without rescue medication, a significantly greater proportion of patients receiving tralokinumab versus placebo achieved EASI-50 (33.0% vs 13.0%), a ≥ 3-point improvement in itch NRS (22.6% vs 9.4%), or a ≥ 4-point improvement in DLQI (41.2% vs 24.5%) at week 16. In addition, compared with placebo, a numerically greater proportion of tralokinumab-treated patients achieved all three measures of clinically meaningful response (30% vs 18%) or a clinically meaningful change in at least one outcome (48.8% vs 28.5%). Significantly greater proportions of patients receiving tralokinumab versus placebo achieved additional clinician-reported and patient-reported outcomes, such as EASI-75 (13.5% vs 4.1%), EASI-90 (3.5% vs 1.1%), DLQI ≤ 5 (22.5% vs 12.5%), and a ≥ 3-point improvement in sleep NRS (24.5% vs 11.5%). Conclusions: Tralokinumab provided clinically meaningful responses in patients with moderate-to-severe atopic dermatitis who did not achieve IGA 0/1 at week 16 and/or used rescue medication. Using multiple validated outcome measures of both efficacy and quality of life, alongside IGA scores, can better characterize tralokinumab treatment responses in patients with moderate-to-severe atopic dermatitis.

Background: Atopic dermatitis is a common chronic, relapsing, and remitting inflammatory skin disorder associated with cutaneous dysbiosis. Current treatment options often fail to adequately control the disease and have unfavorable safety profiles. There is a need for new options that address these treatment shortcomings. Objective: The aim of the study was to evaluate the efficacy, safety, and tolerability of FB-401, a live therapeutic product of 3 strains of Roseomonas mucosa, compared to matching placebo applied topically 3 times per week to participants ages ≥2 years of age with mild-to-moderate atopic dermatitis. Methods: A randomized, double-blind, placebo-controlled, parallel-group study was conducted. The primary outcome was the proportion of participants with 50% improvement in Eczema Area and Severity Index score from baseline at week 16. 154 subjects aged 2 or older with a clinical diagnosis of atopic dermatitis as defined by Hanifin and Rajka criteria with mild or moderate severity were randomized 1:1 via interactive web response system to FB-401 or placebo. Results: The proportion of subjects who achieved the primary outcome was similar between both treatment groups, with no significant treatment group differences observed at any post-baseline visit. The number of treatment-emergent adverse events and the number of subjects with at least one were similar across treatment groups. One serious adverse event not related to treatment was reported. No treatment-emergent adverse events led to treatment discontinuation or study discontinuation. Conclusions: FB-401 showed an acceptable safety profile but failed to prove superior to placebo in treating children and adults with mild-to-moderate atopic dermatitis. [ABSTRACT FROM AUTHOR]

Background: Two phase III trials, ECZTRA 1 and 2, confirmed the efficacy and safety of tralokinumab versus placebo in adults with moderate-to-severe atopic dermatitis (AD). To further explore the long-term efficacy of tralokinumab for AD, a pooled analysis of these trials was conducted. Methods: ECZTRA 1 and 2 patients (n = 1596 total) were randomized to tralokinumab 300 mg or placebo every 2 weeks (q2w) over 16 weeks. Patients achieving Investigator's Global Assessment of clear/almost clear skin (IGA 0/1) and/or 75% improvement in the Eczema Area and Severity Index (EASI-75) at Week 16, were re-randomized to tralokinumab q2w, every 4 weeks (q4w), or placebo (tralokinumab withdrawal) for another 36 weeks. Patients not achieving the response criteria at Week 16 received open-label tralokinumab q2w plus optional topical corticosteroids (TCS). A pooled, prespecified analysis assessed the proportions of Week 16 responders that maintained IGA 0/1 and/or EASI-75 at Week 52. Pooled data from all patients initiated with tralokinumab, regardless of the response at Week 16 or dosing regimen received thereafter, were analyzed post hoc. Results: In patients who achieved the primary endpoints at Week 16, IGA 0/1 responses were maintained at Week 52 without rescue treatment (including TCS) by 55.9%, 42.4%, and 34.0% of patients re-randomized to tralokinumab q2w, q4w, or placebo (tralokinumab withdrawal), respectively, while EASI-75 responses were maintained by 57.3%, 50.4%, and 26.4%, respectively (prespecified analysis). In a post hoc analysis of all patients initiated with tralokinumab, response rates improved over time with continued tralokinumab treatment beyond Week 16 to Week 52 for EASI-50 (63.1–82.7%), EASI-75 (37.6–61.8%), EASI-90 (20.4–37.3%), and IGA 0/1 (23.0–36.2%). Conclusions: Tralokinumab treatment provides progressive and sustained improvement over 1 year in the extent and severity of AD in patients with moderate-to-severe AD. Clinical Trial Registration: NCT03131648 (ECZTRA 1); study start date: 30 May 2017; primary completion date: 7 August 2018; study completion date: 10 October 2019. NCT03160885 (ECZTRA 2); study start date: 12 June 2017; primary completion date: 4 September 2019; study completion date: 14 August 2019. Infographic: Plain Language Summary: Atopic dermatitis (AD) is a chronic inflammatory disease characterized by excessively dry and itchy skin, resulting in a considerable burden of disease. Patients with AD often require long-term treatment. Tralokinumab is an injectable antibody treatment that targets a protein called interleukin-13, which substantially contributes to the signs and symptoms of AD. In the ECZTRA 1 and 2 phase III clinical trials, funded by LEO Pharma A/S, adults with moderate-to-severe AD treated with tralokinumab every other week for 16 weeks showed significant improvement in disease extent and severity compared with patients receiving placebo. To further explore the long-term efficacy of tralokinumab for AD, we performed a new analysis combining the almost 1600 patients of ECZTRA 1 and 2. A large proportion of patients treated with tralokinumab who achieved clear or almost clear skin at Week 16 were able to maintain clear or almost clear skin at Week 52 with less frequent dosing (every 4 weeks). Additionally, combining all patients treated with tralokinumab, regardless of Week 16 response or dose frequency thereafter, showed that most patients achieved a significant reduction in disease extent and severity at Week 52. These results demonstrate that many tralokinumab-treated patients continue to improve beyond Week 16, and highlight that efficacy results at Week 16 may not be representative of the outcome of longer-term tralokinumab treatment. These findings may help health care providers better advise patients regarding when to modify treatment with tralokinumab. [ABSTRACT FROM AUTHOR]

Background: While the majority of patients with atopic dermatitis (AD) achieve disease control with dupilumab treatment, there is variability in which patients achieve clear disease. The predictors of these responses are currently unclear. Integrated models were developed to evaluate the exposure–response (E-R) relationship of dupilumab in children, adolescents, and adults with AD. Methods: Data from six Phase II and III clinical studies were pooled (2,366 adults [> 18 years], 243 adolescents [≥ 12 to < 18 years] and 359 children [≥ 6 to < 12 years]) for model development. Efficacy was assessed using the Eczema Area and Severity Index (EASI) and Investigator's Global Assessment (IGA). Indirect response models were applied to link measures of efficacy and functional serum dupilumab concentrations. The covariates on individual placebo-corrected response were assessed. Clinical trial scenarios were simulated to compare E-R relationships across age groups. Safety was not explored. Results: After correcting for differences in placebo response and dupilumab exposure: 1) older age, higher body weight, lower baseline thymus and activation-regulated chemokine, and Asian race were associated with slightly lower EASI response, and no clear covariates were identified on IGA response; 2) clinical trial simulations generally showed slightly higher response at a given dupilumab concentration in children compared to adults and adolescents with severe and moderate AD. Conclusions: The collectively tested covariates explain some of the variability in dupilumab response in patients with AD. Patients in all age groups showed adequate response to dupilumab; however, children showed slightly higher drug effects compared to adults and adolescents at equivalent concentrations.

Introduction/Background The SCORing Atopic Dermatitis (SCORAD) index is a validated clinician-reported measurement used to assess the extent and intensity of atopic dermatitis (AD). Multiple severity threshold bands have been published to translate the SCORAD's numeric scoring index into clinically meaningful categories, most of which were developed using small patient numbers in clinical practice. Further analyses using larger patient numbers from other clinical settings may provide additional insights into AD severity and outcomes. Objective To report an analysis of SCORAD severity bands using a large, pooled dataset of global, randomized, placebo-controlled clinical trials of dupilumab in adults with moderate-to-severe AD. Methods Data were collected during 2013–2016 from 5 double-blind, randomized, placebo-controlled trials of dupilumab in adults with moderate-to-severe AD (NCT01859988, NCT02277743, NCT02277769, NCT02260986, NCT02755649). Total SCORAD (range 0–103) data from all patients receiving dupilumab and placebo were pooled from all visits, excluding first visit. SCORAD values were anchored to the Investigator's Global Assessment (IGA) and designated into 5 severity categories: Clear, Almost Clear, Mild, Moderate, and Severe. Spearman's rank correlations were calculated between total SCORAD and IGA values. For each integer value of SCORAD, the following were calculated to determine potential threshold bands: means analyzed with spline regression (which accounts for potential non-linear relationships between anchor and outcome, and provides a broader range of potential thresholds); medians and modes; frequencies (where the threshold of the first severity band was set to 0 and each successive severity band was set at the value of the outcome measure where the maximum anchor frequency changes category); and results of previous analyses by Chopra et al. (Br J Dermatol. 2017;177:1316-21) and Kunz et al. (Dermatology. 1997;195:10-19), modified to incorporate 5 severity categories. Thresholds for body surface area (BSA, 0–100) and total SCORAD subscales (observed SCORAD [oSCORAD, 0–83], Pruritus Visual Analog [VAS, 0–10], and Sleep Loss VAS [0–10]) by medians were also evaluated. Goodness-of-fit and concordance between bands and anchors were assessed using R2 and quadratic weighted kappa (κ)-coefficients. Results Data from 31,367 visits from 2,822 adults with moderate-to-severe AD were used. The following banding thresholds were identified using the frequencies, medians, and modes: 0–4.9 (Clear), 5–17.9 (Almost Clear), 18–36.9 (Mild), 37–68.9 (Moderate), and 69–103 (Severe; R2: 0.997; κ: 0.831). Bands identified using the means were similar: 0–5.9 (Clear), 6–17.9 (Almost Clear), 18–36.9 (Mild), 37–77.9 (Moderate), 78–103 (Severe; R2: 0.999; κ: 0.815). Severity thresholds evaluated using modified results from Chopra et al. and Kunz et al. produced the following bands, respectively: 0–5.9 (Clear), 6–24.9 (Almost Clear), 25–49.9 (Mild), 50–77.9 (Moderate), and 78–103 (Severe; R2: 0.998; κ: 0.742); and 0–9.9 (Clear), 10–28.9 (Almost Clear), 29–39.9 (Mild), 40–77.9 (Moderate), and 78–103 (Severe; R2: 0.998; κ: 0.769). Analysis of BSA and SCORAD subscales by medians produced the following bands: BSA – 0–0.09 (Clear), 1–4.9 (Almost Clear), 5–22.9 (Mild), 23–79.9 (Moderate), and 80–100 (Severe); oSCORAD - 0–4.9 (Clear), 5–15.9 (Almost Clear), 16–31.9 (Mild), 32–58.9 (Moderate), and 59–83 (Severe); Pruritus VAS - 0–1.9 (None), 2–4.9 (Mild), 5–8.9 (Moderate/Severe), and 9–10 (Very Severe); and Sleep Loss VAS - 0–0.9 (None), 1–3.9 (Mild), 4–8.9 (Moderate), and 9–10 (Severe/Very Severe). Conclusions The SCORAD threshold bands developed in this anchor-based analysis utilized a large, global, diverse data set of adult patients with AD from clinical trials and used spline regressions as a novel methodology. These potential severity bands may enhance the understanding of AD severity and disease stratification. [ABSTRACT FROM AUTHOR]

Despite the need for improved eczema therapies and a rapid increase in available eczema clinical trials, participation remains low. The aim of this study was to identify factors associated with clinical trial awareness, interest, and barriers to enrolment and participation. An online survey, administered 1 May to 6 June 2020 to adults (≥18 years) with eczema in the USA, was analysed. Among 800 patients included, mean age was 49.4 years, most respondents were female (78.1%), White (75.4%), non-Hispanic (91.4%), and geographically living in an urban/suburban area (Rural-Urban Continuum Codes (RUCC) 1–3, 90.8%). Only 9.7% of respondents reported previous participation in clinical trials, while 57.1% had considered participation and 33.2% never considered participation. Higher satisfaction with current eczema therapy, clinical trial literacy, and confidence in finding eczema trial information were all associated with clinical trial awareness, interest, and successful participation. Younger age and having atopic dermatitis were associated with increased awareness, while female gender was a barrier to interest and successful participation. [ABSTRACT FROM AUTHOR]

To address the need for long‐term efficacy and patient‐reported outcomes (PROs) data for patients with atopic dermatitis (AD) treated with baricitinib 2 mg, a study was conducted to evaluate the efficacy of baricitinib 2 mg in adult patients with moderate‐to‐severe AD. Data presented here provided efficacy and outcomes data for patients treated for 52 weeks. Patients who participated in the originating study, BREEZE‐AD5 (NCT03435081), and met additional eligibility criteria could enroll in the multicenter, open‐label, Phase 3, long‐term extension study BREEZE‐AD6 (NCT03559270). Patients received baricitinib 2 mg for the duration of BREEZE‐AD6. In BREEZE‐AD6, the proportion of patients who achieved a 75% improvement in the Eczema Area and Severity Index (EASI75) and validated Investigator Global Assessment for AD (vIGA‐AD™) of 0 (clear) or 1 (almost clear) were assessed through 52 weeks, in addition to several PROs. At week 52, the proportion of patients treated with baricitinib 2 mg daily achieving EASI75 was 48.6% (70/144), and 31.3% (45/144) of patients achieved a vIGA‐AD score of 0 or 1 (clear or almost clear). Improvements in PROs such as SCORing Atopic Dermatitis (SCORAD, itch and sleep) scores, Dermatology Life Quality Index (DLQI) total score, and DLQI ≤5 response were observed, and these responses were sustained through 52 weeks. Long‐term efficacy of baricitinib in patients with AD was demonstrated by both clinician and patient‐reported outcome measures. [ABSTRACT FROM AUTHOR]

The pharmacokinetics (PKs) and exposure–efficacy of dupilumab have not been fully described for adults with atopic dermatitis (AD). Our objectives were to analyze the PKs and exposure–efficacy of dupilumab in adults with AD and compare the results of Japanese and overall populations. Adults with moderate‐to‐severe AD were randomly assigned to dupilumab (300 mg weekly [qw] or every 2 weeks [q2w], 200 mg q2w, 300 mg every 4 weeks [q4w], or 100 mg q4w) or placebo for 16 weeks in a randomized, double‐blind, placebo‐controlled, dose‐ranging phase IIb trial (NCT01859988). This analysis included 379 patients (58 Japanese). Functional dupilumab concentrations increased in a dose‐dependent manner; at lower concentrations, increases were greater than dose‐proportional because of nonlinear, target‐mediated clearance. Dupilumab pharmacokinetics were comparable in Japanese and non‐Japanese patients with similar body weights. Week 16 efficacy parameters, including Investigator's Global Assessment score 0/1, greater than or equal to 75% reduction from baseline in the Eczema Area and Severity Index (EASI), and percentage change from baseline in EASI and pruritus Numerical Rating Scale, generally increased with week 16 trough concentration; the plateau of these exposure–efficacy relationships occurred for most patients at exposures associated with the 300 mg q2w and 300 mg qw regimens. Japanese ethnicity did not remain in the population PK model as covariate with or without accounting for body weight differences. In Japanese and non‐Japanese patients, efficacy responses increased with week 16 dupilumab trough concentrations in a similar manner. Dupilumab 300 mg qw and q2w regimens were recommended for further evaluation in larger phase III studies. [ABSTRACT FROM AUTHOR]

Introduction: Previous drug survival studies of dupilumab in atopic dermatitis (AD) show that many patients continue treatment through 1 year, suggesting that patients experience clinically relevant benefits with long-term treatment. Methods: This post hoc analysis included data through week 100 from 391 adult patients from the dupilumab open-label extension (OLE) study who had not achieved the endpoints of at least 75% improvement from baseline in the Eczema Area and Severity Index (EASI-75) or an Investigator's Global Assessment (IGA) score of 0 or 1 with short-term (16 weeks, 300 mg qw or q2w) dupilumab treatment in the parent SOLO 1 or 2 studies. All patients received dupilumab 300 mg qw in the OLE study, irrespective of whether they received qw or 2qw dosing in the parent study. Results: Among those who had not achieved EASI-75 or IGA 0/1 during the 16-week parent study, the proportion of patients achieving EASI-75 by week 100 was 91%. The proportion achieving IGA 0 or 1 at week 100 was 45% for patients initially on q2w week dosing and 49% for those on initial qw dosing. Conclusion: Long-term dupilumab treatment may be associated with improvement in AD in patients with suboptimal responses during the initial 16 weeks of treatment.

Introduction: In a 52-week, phase 3 clinical trial (LIBERTY AD CHRONOS) in adult patients with moderate-to-severe atopic dermatitis (AD), dupilumab in combination with topical corticosteroids (TCS) resulted in a significant improvement in overall Eczema Area and Severity Index (EASI) compared with placebo plus TCS. In a post hoc analysis, dupilumab significantly improved the overall extent and severity of AD across four anatomic regions (head and neck, trunk, upper extremities, lower extremities) over 16 weeks. However, as AD severity and presentation may vary by body region, this analysis sought to determine whether there are regional variations in dupilumab efficacy. Methods: Using data from the LIBERTY AD CHRONOS study, we performed a post hoc analysis of the mean percentage change in individual EASI signs (erythema, infiltration/papulation, excoriation, lichenification) from baseline through week 52 across four anatomic regions (head and neck, trunk, upper extremities, lower extremities). Results: Dupilumab plus TCS, compared with placebo plus TCS, significantly improved the severity of all individual AD signs to a similar extent across the four anatomic regions. Significant improvements in each sign were seen early, within the first 2–4 weeks of treatment, and were sustained through week 52 across all regions. Conclusions: In adult patients with moderate-to-severe AD, treatment with dupilumab resulted in rapid and sustained improvement in the signs of AD across all anatomic regions. Trial registration: LIBERTY AD CHRONOS (NCT02260986). [ABSTRACT FROM AUTHOR]

Optimal management of atopic dermatitis requires a comprehensive assessment of response to treatment in order to inform therapeutic decisions. In a realworld setting, successful response to atopic dermatitis treatment is measured by sustained improvements in signs, symptoms, and quality of life. Post-hoc analyses of a 1-year, randomized, double-blinded, placebocontrolled trial (NCT02260986) of dupilumab with concomitant topical corticosteroids in 421 adults with moderate-to-severe atopic dermatitis (of whom 315/106 received placebo/dupilumab (of whom 315 received placebo and 106 received dupilumab) was performed to assess the proportion of responders to dupilumab through a multidimensional composite endpoint. At 6-months, 80.2% of dupilumab-treated vs 40.0% placebo patients (p < 0.0001) achieved improvement in signs (Eczema Area and Severity Index ≤ 7), symptoms (worst itch score ≤ 4), or quality of life (Dermatology Life Quality Index ≤5), representative of minimal/clear atopic dermatitis. All 3 endpoints, indicative of no/minimal atopic dermatitis, were achieved by 44.3% of dupilumab-treated vs 10.2% placebo patients (p < 0.0001) and sustained through 1 year. Dupilumab treatment provided sustained clinically meaningful improvement in signs, symptoms, and quality of life in adults with moderate-to-severe atopic dermatitis. [ABSTRACT FROM AUTHOR]

Dupilumab demonstrated efficacy with an acceptable safety profile in two randomized, double‐blind, placebo‐controlled, parallel‐group, phase III trials in adolescents (12–17 years; LIBERTY AD ADOL) and children (6–11 years; LIBERTY AD PEDS) with atopic dermatitis (AD) treated for 16 weeks. Here, we present the pharmacokinetic profiles and exposure‐response (E‐R) relationships of dupilumab that guided the posology in these populations. A total of 251 adolescent patients with moderate‐to‐severe AD were randomized to subcutaneous dupilumab monotherapy every 2 weeks (q2w; 200 mg q2w, baseline weight < 60 kg; 300 mg q2w, ≥ 60 kg), dupilumab 300 mg every 4 weeks (q4w; non‐weight tiered), or placebo; 367 children with severe AD were randomized to dupilumab q2w (100 mg q2w, baseline weight < 30 kg; 200 mg q2w, ≥ 30 kg), dupilumab 300 mg q4w, or placebo. Children received concomitant topical corticosteroids in addition to dupilumab, and loading doses were administered at the start of therapy. Mean dupilumab trough concentrations at week 16 for weight subcategories in each dosing regimen were compared with adult exposures for the approved dupilumab 300 mg q2w regimen. Positive E‐R relationships were demonstrated between dupilumab trough concentrations and AD outcome measures across patient populations and regimens; no relationship was observed with treatment‐emergent conjunctivitis. Based on these analyses, a weight‐tiered posology was proposed for adolescents (200/300 mg q2w in patients 30–< 60 kg/≥ 60 kg) and children (300 mg q4w in patients 15–< 30 kg, 200 mg q2w in patients 30–< 60 kg) with moderate‐to‐severe AD.

Atopic dermatitis (AD) is a heterogeneous systemic inflammatory skin disease associated with dysregulated immune responses, barrier dysfunction and activated sensory nerves. To characterize circulating inflammatory profiles and underlying systemic disease heterogeneity within AD patients, blood samples from adult patients (N = 123) with moderate‐to‐severe AD in a phase 2 study of baricitinib (JAHG) were analysed. Baseline levels of 131 markers were evaluated using high‐throughput and ultrasensitive proteomic platforms, patient clusters were generated based on these peripheral markers. We implemented a novel cluster reproducibility method to validate cluster outcomes within our study and used publicly available AD biomarker data set (73 markers, N = 58 patients) to validate our findings. Cluster reproducibility analysis demonstrated best consistency for 2 clusters by k‐means, reproducibility of this clustering outcome was validated in an independent patient cohort. These unique JAHG patient subgroups either possessed elevated pro‐inflammatory mediators, notably TNFβ, MCP‐3 and IL‐13, among a variety of immune responses (high inflammatory) or lower levels of inflammatory biomarkers (low inflammatory). The high inflammatory subgroup was associated with greater baseline disease severity, demonstrated by greater EASI, SCORAD Index, Itch NRS and DLQI scores, compared with low inflammatory subgroup. African‐American patients were predominantly associated with the high inflammatory subgroup and increased baseline disease severity. In patients with moderate‐to‐severe AD, heterogeneity was identified by the detection of 2 disease subgroups, differential clustering amongst ethnic groups and elevated pro‐inflammatory mediators extending beyond traditional polarized immune responses. Therapeutic strategies targeting multiple pro‐inflammatory cytokines may be needed to address this heterogeneity. [ABSTRACT FROM AUTHOR]

Background: Baricitinib, an oral selective Janus kinase 1/Janus kinase 2 inhibitor, is being studied for moderate-to-severe atopic dermatitis (AD) in adults.Objective: To evaluate the efficacy and safety of baricitinib monotherapy in a North American phase 3 trial (BREEZE-AD5/NCT03435081) of adults with moderate-to-severe AD who responded inadequately or were intolerant to topical therapy.Methods: Patients (N = 440) were randomized 1:1:1 to once-daily placebo or baricitinib (1 mg or 2 mg). The primary endpoint was the proportion of patients achieving ≥75% reduction in the Eczema Area and Severity Index at week 16. A key secondary endpoint was the proportion of patients achieving a validated Investigator Global Assessment for AD score of 0 (clear)/1(almost clear) with ≥2-point improvement.Results: At week 16, the proportion of patients achieving Eczema Area and Severity Index was 8%, 13%, and 30% (P < .001, 2 mg vs placebo) and those with a validated Investigator Global Assessment for AD score of 0/1 were 5%, 13%, and 24% (P < .001, 2 mg vs placebo) for placebo, baricitinib 1 mg, and baricitinib 2 mg, respectively. Safety findings were similar to those of other baricitinib AD studies.Limitations: Short-term clinical trial results may not be generalizable to real-world settings.Conclusion: Baricitinib was efficacious for patients with moderate-to-severe AD with no new safety findings over 16 weeks.

Background: Atopic dermatitis imparts a substantial patient burden, including itch, sleep disturbance, and decreased health-related quality of life. Objective: This analysis evaluated changes in patient-reported outcomes of disease-specific signs/symptoms and health-related quality of life in adult and adolescent patients with moderate-to-severe atopic dermatitis treated with once-daily oral abrocitinib 200-mg or 100-mg monotherapy. Methods: Pooled data from one phase IIb (NCT02780167) and two phase III (NCT03349060, JADE MONO-1; NCT03575871, JADE MONO-2) monotherapy trials in adult and adolescent patients with moderate-to-severe atopic dermatitis were analyzed. Patient-reported outcome assessments included: global severity, itch, and multi-item measures that assess other signs and symptoms of atopic dermatitis. Additional patient-reported outcome assessments measured depression, anxiety, fatigue, disease-specific and general health-related quality of life, and work and general productivity among employed patients. Results: Overall, 942 patients were included in this analysis. Improvements were observed from the first post-baseline assessment to week 12 across all patient-reported outcomes, including Patient Global Assessment (PtGA) score of 0/1 (35.5%, 19.8%, and 5.9% for 200 mg, 100 mg, and placebo, respectively), ≥ 4-point improvement in Night Time Itch Scale (NTIS; 57.0%, 42.7%, and 12.7%), change from baseline in Patient-Oriented Eczema Measure (POEM) score (− 11.4, − 8.2, and − 3.4), 1-point improvement in Pruritus and Symptoms Assessment for Atopic Dermatitis (PSAAD; 75.2%, 65.1%, and 33.5%), Hospital Anxiety and Depression Scales (HADS) anxiety (− 2.0, − 1.7, and − 1.0) and depression (− 1.7, − 1.3, and − 0.1). Conclusions: Abrocitinib monotherapy improved disease-specific signs/symptoms and health-related quality of life across multiple domains as reported by adult and adolescent patients with moderate-to-severe atopic dermatitis, complementing clinician-reported efficacy and safety outcomes.

Introduction & Objectives: Upadacitinib (UPA) is an oral Janus kinase 1 (JAK1) inhibitor approved in multiple countries for the treatment of adolescents and adults with moderate-to-severe atopic dermatitis (AD). Here, we present the efficacy and safety of UPA administered over 140 weeks in an ongoing randomized, double-blinded, multicenter phase 3 study (Measure Up 1, NCT03569293). Materials & Methods: Patients (12-75 years) with moderate-to-severe AD were randomized 1:1:1 to receive UPA 15 mg (UPA15), UPA 30 mg (UPA30), or placebo (PBO) once daily at baseline. At week 16, PBO-treated patients were re-randomized 1:1 to receive UPA15 (PBO/UPA15) or UPA30 (PBO/UPA30) once daily. Co-primary endpoints were the proportion of patients achieving ≥75% reduction in EASI (EASI 75) from baseline and vIGA-AD of clear (0) or almost clear (1) with ≥2 grades of reduction from baseline (vIGA-AD 0/1) at week 16. A meaningful improvement in itch, defined as a ≥4-point reduction in Worst Pruritus Numeric Rating Scale (ΔWP-NRS≥4), was assessed among patients with baseline WP-NRS≥4. All efficacy endpoints were summarized using the Observed Cases (OC) approach, and no missing data imputation was applied. Safety was assessed by monitoring of serious adverse events (SAEs), treatment-emergent adverse events (TEAEs), and treatment-emergent adverse events of special interest (AESI), which were analysed as exposure-adjusted rates per 100 patient-years (PY). Results: Efficacy results were sustained up to week 140 since week 16. Proportions of patients in the UPA15 (205), UPA30 (206), PBO/UPA15 (91), and PBO/UPA30 (94) groups achieving EASI 75 at week 140 were 88.8% (182), 90.3% (186), 83.5% (76), and 89.4% (84), respectively, and for vIGA-AD 0/1 was 63.4% (130), 65.5% (135), 60.4% (55), and 75.5% (71), respectively. Proportions of patients achieving an improvement (reduction) in WP-NRS≥4 from baseline at week 140 were 68.0% (136), 70.5% (146), 71.3% (62), and 81.3% (74) respectively. Overall, the rates of AESIs were similar across treatment groups, which aligned with prior reports at earlier time points. Both UPA15 and UPA30 were well-tolerated in all patients, and no new safety signals were observed compared to the known safety profile of UPA. Data from two additional pivotal studies will be available at the time of presentation. Conclusion: In this interim analysis, sustained skin clearance and itch and a consistent safety profile were observed with UPA 15 mg and UPA 30 mg across 140 weeks in adolescent and adult patients with moderate-to-severe AD.

Background: Pruritus (itch) is a cardinal symptom in atopic dermatitis (AD).Objective: To evaluate the timing and effect of dupilumab on itch.Methods: Analysis of data from 1505 patients with moderate to severe AD included in 4 randomized controlled studies, treated for up to 52 weeks. Adults received dupilumab 300 mg every 2 weeks or placebo monotherapy (SOLO 1: NCT02277743; SOLO 2: NCT02277769), with concomitant topical corticosteroids (CHRONOS: NCT02260986); adolescents (≥12 to <18 y) were treated with dupilumab monotherapy every 2 weeks (200 mg for baseline weight of <60 kg; 300 mg for baseline weight of ≥60 kg) or placebo (AD ADOL: NCT03054428).Results: Dupilumab showed significant rapid improvements from baseline in daily Peak Pruritus Numerical Rating Scale scores versus placebo, by day 2 in adults and day 5 in adolescents. At treatment end, dupilumab vs placebo/control had greater least-squares mean percent change from baseline in the weekly average of Peak Pruritus Numerical Rating Scale scores: SOLO -47.5% vs -20.5%; AD-ADOL -47.9% vs -19.0%; CHRONOS -57.3% vs -30.9% (P < .0001 for all).Limitations: Short duration of monotherapy trials (16 weeks).Conclusion: Across 4 randomized trials, dupilumab treatment showed rapid and sustained improvements in the magnitude of itch, starting with first dose; responses progressively increased and were sustained through to the end of treatment, up to 1 year.

• In this pooled analysis dupilumab significantly improved signs and symptoms of AD. • Dupilumab treatment alleviated pain/discomfort on the EuroQoL-5D. • Patient distribution within responder categories improved over time with dupilumab. • No new safety signals were observed with dupilumab. • Dupilumab had an overall favorable benefit-risk profile. Two phase 3 trials with identical design, LIBERTY AD SOLO 1 (NCT02277743) and LIBERTY AD SOLO 2 (NCT02277769), confirmed dupilumab efficacy and safety versus placebo in adults with moderate-to-severe atopic dermatitis (AD). To report a pooled analysis of these trials to further explore dupilumab's effects on AD clinical parameters, patient-reported outcomes (PROs), symptoms of anxiety/depression, health-related quality of life (HRQoL), and safety. A pooled analysis of two 16-week phase 3 studies in adults with moderate-to-severe AD (N = 1379) inadequately controlled with/inadvisable for topical medications, randomized to dupilumab 300 mg once weekly (qw), every 2 weeks (q2w), or placebo. Dupilumab significantly improved all pre-specified efficacy endpoints versus placebo (P < 0.0001), including clinical severity outcomes and PROs, symptoms of anxiety/depression, and HRQoL, consistent with previously published results. In post-hoc analyses, among patients reporting at least some baseline pain/discomfort on the EuroQoL-5D, no pain/discomfort at Week 16 was reported by 43%/46%/14% of dupilumab qw/q2w/placebo-treated patients (P < 0.0001). The distribution of dupilumab-treated patients within pre-defined score categories on the Investigator's Global Assessment (0–1/2/3/4) and Eczema Area and Severity Index (≥90%/≥75–<90%/≥50–<75%/<50%) steadily and consistently improved over time versus marginal changes with placebo. Dupilumab significantly improved pruritus within 1–3 days of treatment initiation. No new safety signals were observed. Injection-site reactions and conjunctivitis were more common with dupilumab; AD exacerbation and non-herpetic skin infections more frequent with placebo. Dupilumab versus placebo significantly improved objective AD signs, subjective PROs, symptoms of anxiety/depression, and HRQoL, with a favorable benefit-risk profile in adults with moderate-to-severe AD.

Background and purpose: There is a need for new treatment options for moderate-to-severe atopic dermatitis (AD) in adults. Dupilumab, a fully human anti-interleukin-4 receptor a monoclonal antibody, has recently been approved for this indication. Methods: A pooled analysis of a phase 2a (NCT01548404) and a phase 2b (NCT01859988) study and a subanalysis of the 2b study evaluated the efficacy and safety of subcutaneous dupilumab 300 mg once weekly (qw) and every 2 weeks (q2w) in adults with moderate-to-severe AD. Results: Dupilumab significantly improved clinical outcomes in both analyses at week 12. Itch was significantly improved in the pooled analysis as measured by peak pruritus Numerical Rating Scale, 5-dimension pruritus scale, and SCORing Atopic Dermatitis (SCORAD) Visual Analog Scale (VAS) pruritus scores (all p < .0001 vs. placebo at week 12). Sleep loss was significantly improved (SCORAD VAS sleep loss score; p < .0001 vs. placebo at week 12); similar results were shown for the q2w dose. Dupilumab had an acceptable safety profile. Conclusions: Consistent with previous studies, dupilumab qw and q2w significantly improved signs and symptoms of AD at week 12, including improvements in itch and sleep loss. Implications for practice: Subcutaneous dupilumab is an effective new treatment option for adults with moderateto- severe AD. [ABSTRACT FROM AUTHOR]

Background: Moderate to severe atopic dermatitis (AD) is associated with substantial patient burden despite current therapies.Objective: We sought to evaluate dupilumab treatment on patient-reported outcomes in adults with moderate to severe AD.Methods: Adults (N = 380) with moderate to severe AD inadequately controlled by topical medications were randomized to 16 weeks of double-blind, subcutaneous treatment with dupilumab 100 mg every 4 weeks, 200 mg every 2 weeks, 300 mg every 2 weeks, 300 mg once weekly, or placebo. Patient-reported outcomes included pruritus numeric rating scale; patient-reported sleep item on Scoring AD scale; Patient-Oriented Eczema Measure; Hospital Anxiety and Depression Scale; Dermatology Life Quality Index; and 5-dimension 3-level EuroQol.Results: Dupilumab reduced peak itch at 16 weeks relative to placebo by 1.1 to 3.2 points on numeric rating scale (P < .0001 all doses, except 100 mg every 4 weeks P < .05); improved sleep and health-related quality of life on Dermatology Life Quality Index and 5-dimension 3-level EuroQol (P < .05 all doses, except 100 mg every 4 weeks); and reduced anxiety and depression symptoms (P < .05 all doses). Dupilumab's effects appeared early and achieved clinically relevant improvements without significant safety concerns.Limitations: There are potential cultural differences affecting patient-reported outcome responses. Outcomes were secondary or exploratory end points.Conclusion: Dupilumab produced early and sustained patient-reported and clinically relevant improvements in sleep, mental health, and health-related quality of life; the two 300-mg dose regimens resulted in greatest benefits.

Background: The adult burden of atopic dermatitis (AD) is poorly characterized.Objective: We sought to characterize AD burden in adults with moderate to severe disease from the patient's perspective.Methods: Patient-reported outcomes collected at screening in a phase 2b clinical trial of dupilumab included pruritus numeric rating scale, 5-Dimension Pruritus Scale, subjective components of SCORing AD, Patient-Oriented Eczema Measure, Hospital Anxiety and Depression Scale, Dermatology Life Quality Index, and 5-Dimension EuroQol.Results: Most of the 380 patients had been living with AD for nearly all their lives, whereas approximately 40% were given a diagnosis as adults; 40.3% had asthma and 60.5% had other allergic conditions. Despite 48.2% of patients using systemic therapies in the past year, patients reported problems with itch frequency (85% of patients), duration (41.5% reported itching ≥18 h/d), and severity (6.5 of 10 on numeric rating scale); 55% reported AD-related sleep disturbances 5 d/wk or more. Hospital Anxiety and Depression Scale scores suggesting clinically relevant anxiety or depression were reported by 21.8% of patients. Quality of life was impaired on Dermatology Life Quality Index and 5-dimension EuroQol.Limitations: This study had limited generalizability; conclusions may not reflect those with mild AD or not participating in a clinical trial.Conclusions: Adults with moderate to severe AD report multidimensional burden including disease activity, patient-reported symptoms, comorbidities, and quality-of-life impact.

Accordingly, the specific references to these instruments should be deleted, and the sentence should read as follows:Furthermore, PSAAD was developed to meet regulatory guidance and to be included in product-labelling claims in the USA and Europe. However, these instruments, including the Peak Pruritus Numerical Rating Scale, have either accumulated sufficient evidence to meet regulatory guidance related to product-labelling claims and/or have since been recommended for use in clinical trials. The Discussion section of the original publication previously said:Furthermore, PSAAD was developed to meet regulatory guidance and - unlike POEM, Itch Numeric Rating Scale (v2.0), Skin Pain Numeric Rating Scale (v2.0b), and Peak Pruritus Numerical Rating Scale - to be included in product-labelling claims in the USA and Europe.

A correction to the article "Impact of Oral Abrocitinib Monotherapy on Patient-Reported Symptoms and Quality of Life in Adolescents and Adult with Moderate-to-Severe Atopic Dermatitis: A Pooled Analysis of Patient-Reported Outcomes" in an issue is presented.

Background: Upadacitinib is an oral Janus kinase (JAK) inhibitor with greater inhibitory potency for JAK1 than JAK2, JAK3, and tyrosine kinase 2. We aimed to assess the efficacy and safety of upadacitinib compared with placebo for the treatment of moderate-to-severe atopic dermatitis.Methods: Measure Up 1 and Measure Up 2 were replicate multicentre, randomised, double-blind, placebo-controlled, phase 3 trials; Measure Up 1 was done at 151 clinical centres in 24 countries across Europe, North and South America, Oceania, and the Asia-Pacific region; and Measure Up 2 was done at 154 clinical centres in 23 countries across Europe, North America, Oceania, and the Asia-Pacific region. Eligible patients were adolescents (aged 12-17 years) and adults (aged 18-75 years) with moderate-to-severe atopic dermatitis (≥10% of body surface area affected by atopic dermatitis, Eczema Area and Severity Index [EASI] score of ≥16, validated Investigator's Global Assessment for Atopic Dermatitis [vIGA-AD] score of ≥3, and Worst Pruritus Numerical Rating Scale score of ≥4). Patients were randomly assigned (1:1:1) using an interactive response technology system to receive upadacitinib 15 mg, upadacitinib 30 mg, or placebo once daily for 16 weeks, stratified by baseline disease severity, geographical region, and age. Coprimary endpoints were the proportion of patients who had achieved at least a 75% improvement in EASI score from baseline (EASI-75) and the proportion of patients who had achieved a vIGA-AD response (defined as a vIGA-AD score of 0 [clear] or 1 [almost clear] with ≥2 grades of reduction from baseline) at week 16. Efficacy was analysed in the intention-to-treat population and safety was analysed in all randomly assigned patients who received at least one dose of study drug. These trials are registered with ClinicalTrials.gov, NCT03569293 (Measure Up 1) and NCT03607422 (Measure Up 2), and are both active but not recruiting.Findings: Between Aug 13, 2018, and Dec 23, 2019, 847 patients were randomly assigned to upadacitinib 15 mg (n=281), upadacitinib 30 mg (n=285), or placebo (n=281) in the Measure Up 1 study. Between July 27, 2018, and Jan 17, 2020, 836 patients were randomly assigned to upadacitinib 15 mg (n=276), upadacitinib 30 mg (n=282), or placebo (n=278) in the Measure Up 2 study. At week 16, the coprimary endpoints were met in both studies (all p<0·0001). The proportion of patients who had achieved EASI-75 at week 16 was significantly higher in the upadacitinib 15 mg (196 [70%] of 281 patients) and upadacitinib 30 mg (227 [80%] of 285 patients) groups than the placebo group (46 [16%] of 281 patients) in Measure Up 1 (adjusted difference in EASI-75 response rate vs placebo, 53·3% [95% CI 46·4-60·2] for the upadacitinib 15 mg group; 63·4% [57·1-69·8] for the upadacitinib 30 mg group) and Measure Up 2 (166 [60%] of 276 patients in the upadacitinib 15 mg group and 206 [73%] of 282 patients in the upadacitinib 30 mg group vs 37 [13%] of 278 patients in the placebo group; adjusted difference in EASI-75 response rate vs placebo, 46·9% [39·9-53·9] for the upadacitinib 15 mg group; 59·6% [53·1-66·2] for the upadacitinib 30 mg group). The proportion of patients who achieved a vIGA-AD response at week 16 was significantly higher in the upadacitinib 15 mg (135 [48%] patients) and upadacitinib 30 mg (177 [62%] patients) groups than the placebo group (24 [8%] patients) in Measure Up 1 (adjusted difference in vIGA-AD response rate vs placebo, 39·8% [33·2-46·4] for the upadacitinib 15 mg group; 53·6% [47·2-60·0] for the upadacitinib 30 mg group) and Measure Up 2 (107 [39%] patients in the upadacitinib 15 mg group and 147 [52%] patients in the upadacitinib 30 mg group vs 13 [5%] patients in the placebo group; adjusted difference in vIGA-AD response rate vs placebo, 34·0% [27·8-40·2] for the upadacitinib 15 mg group; 47·4% [41·0-53·7] for the upadacitinib 30 mg group). Both upadacitinib doses were well tolerated. The incidence of serious adverse events and adverse events leading to study drug discontinuation were similar among groups. The most frequently reported treatment-emergent adverse events were acne (19 [7%] of 281 patients in the upadacitinib 15 mg group, 49 [17%] of 285 patients in the upadacitinib 30 mg group, and six [2%] of 281 patients in the placebo group in Measure Up 1; 35 [13%] of 276 patients in the upadacitinib 15 mg group, 41 [15%] of 282 patients in the upadacitinib 30 mg group, and six [2%] of 278 patients in the placebo group in Measure Up 2), upper respiratory tract infection (25 [9%] patients, 38 [13%] patients, and 20 [7%] patients; 19 [7%] patients, 17 [16%] patients, and 12 [4%] patients), nasopharyngitis (22 [8%] patients, 33 [12%] patients, and 16 [6%] patients; 16 [6%] patients, 18 [6%] patients, and 13 [5%] patients), headache (14 [5%] patients, 19 [7%] patients, and 12 [4%] patients; 18 [7%] patients, 20 [7%] patients, and 11 [4%] patients), elevation in creatine phosphokinase levels (16 [6%] patients, 16 [6%] patients, and seven [3%] patients; nine [3%] patients, 12 [4%] patients, and five [2%] patients), and atopic dermatitis (nine [3%] patients, four [1%] patients, and 26 [9%] patients; eight [3%] patients, four [1%] patients, and 26 [9%] patients).Interpretation: Monotherapy with upadacitinib might be an effective treatment option and had a positive benefit-risk profile in adolescents and adults with moderate-to-severe atopic dermatitis.Funding: AbbVie.
