Abstract Introduction The treatment landscape for moderate-to-severe atopic dermatitis (AD) continues to expand. This network meta-analysis (NMA) updates a previously conducted NMA to include data from the most recent phase 3 trials to assess the comparative efficacy of targeted systemic therapies without the addition of topical corticosteroids (TCS) and/or topical calcineurin inhibitors (TCI) in adults with moderate-to-severe AD. Methods Data from recent phase 3 monotherapy trials of lebrikizumab, ADvocate1 (NCT04146363) and ADvocate2 (NCT04178967), were included in the analyses, along with other eligible phase 3/4 randomized placebo-controlled trials for abrocitinib, baricitinib, dupilumab, tralokinumab, and upadacitinib identified through a systemic literature review in Silverberg et al. (Dermatol Ther (Heidelb) 12(5):1181–1196, 2022). The proportion of patients achieving Eczema Area and Severity Index (EASI) improvement ≥ 90% from baseline (EASI-90), EASI improvement ≥ 75% from baseline (EASI-75), ≥ 4-point improvement on Pruritus Numerical Rating Scale from baseline (ΔNRS ≥ 4), and Investigator Global Assessment (IGA) score of 0 or 1 (clear or almost clear) and reduction of ≥ 2 points from baseline (IGA 0/1) were evaluated using a Bayesian network meta-analysis. Results The updated NMA analyzed 13 unique placebo-controlled trials involving 7105 patients in 32 arms across 6 targeted therapies. Upadacitinib 30 mg was the most efficacious therapy across all endpoints at the primary timepoint (week 12 or 16) and at earlier timepoints, generally followed by abrocitinib 200 mg, upadacitinib 15 mg, dupilumab 300 mg, and lebrikizumab 250 mg or abrocitinib 100 mg. Baricitinib 2 mg and tralokinumab were generally ranked lower across outcomes. Conclusions Many factors need to be considered for treatment selection for AD, especially as new treatments continue to emerge. After incorporating recent placebo-controlled phase 3 data of lebrikizumab, upadacitinib 30 mg, upadacitinib 15 mg, and abrocitinib 200 mg remain the most efficacious targeted systemic therapies over 12–16 weeks of therapy in AD. These updated findings can help healthcare providers when creating a patient’s personalized treatment plan.

Background: Systemic atopic dermatitis treatments that have acceptable safety are needed. Objective: To evaluate the safety of the oral Janus kinase inhibitor upadacitinib in combination with topical corticosteroids (TCSs) for the treatment of atopic dermatitis. Methods: In this phase 3, double-blind study (Rising Up), Japanese patients (12-75 years) with moderate-to-severe atopic dermatitis were randomized in a 1:1:1 ratio to receive 15 mg of upadacitinib + TCS, 30 mg of upadacitinib + TCS, or a placebo + TCS (rerandomized in a 1:1 ratio to receive either 15 or 30 mg of upadacitinib + TCS at week 16). Adverse events and laboratory data were assessed for safety. Results: In 272 treated patients, the serious adverse event rates were similar for 15- and 30-mg upadacitinib + TCS at week 24 (15 mg, 56%; 30 mg, 64%) but greater than those for placebo + TCS (42%). Acne (all mild or moderate; none leading to discontinuation) occurred more frequently with upadacitinib + TCS (15 mg, 13.2%; 30 mg, 19.8%) than with placebo + TCS (5.6%). Furthermore, herpes zoster infection (4.4% vs 0%), anemia (1.1% vs 0%), neutropenia (4.4% vs 1.1%), and creatine phosphokinase elevations (2.2% vs 1.1%) occurred more frequently with 30-mg upadacitinib + TCS than with 15-mg upadacitinib + TCS; none of these events were reported with placebo + TCS. No thromboembolic events, malignancies, gastrointestinal perforations, active tuberculosis, or deaths occurred. Limitations: The limitations included a small sample size and short observation period as well as nongeneralizability of the results beyond Japanese populations. Conclusions: The results were generally consistent with those of previous reports; no new safety risks were detected.

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. Clinical Trial Registration: ClinicalTrials.gov identifiers NCT03569293 (13 August 2018) and NCT03607422 (27 July 2018). Plain Language Summary: Atopic dermatitis, or eczema, is a condition that causes painful itchy dry skin, which is burdensome for patients and has a negative impact on quality of life. These symptoms frequently lead to disruption of daily activities such as school and work, decreased self-confidence, social isolation, anxiety, depression, and sleep disturbance. Symptoms of atopic dermatitis, such as itch and sleep disturbance, can only be assessed by patients. Therefore, it is important to consider patients' perceptions of their symptoms and the related impact on their quality of life, especially when evaluating treatment benefits. Upadacitinib is an orally administered drug approved to treat moderate-to-severe atopic dermatitis. In two clinical trials (Measure Up 1 and Measure Up 2), we investigated how treatment with upadacitinib (15-mg or 30-mg dose) given once daily to adults and adolescents with moderate-to-severe atopic dermatitis would impact their symptoms and quality of life over a 1-year period. We measured changes over time in patients' assessments of itch, pain, other skin-related symptoms, sleep, daily activities, emotional state, mental health, and overall quality of life. Patients treated with upadacitinib experienced improvements in symptoms of atopic dermatitis and quality of life within the first 1–2 weeks of treatment. These improvements continued to steadily increase in the following weeks and lasted through 1 year of treatment. In conclusion, once-daily treatment with upadacitinib 15 or 30 mg led to early and lasting improvements in the well-being of patients with atopic dermatitis. [ABSTRACT FROM AUTHOR]

Background: Atopic dermatitis (AD), a relapsing, inflammatory skin disease, is associated with pruritus that can negatively affect patients' quality of life. Understanding the burden of AD is critical for informing and tailoring treatment and disease management to improve patient outcomes. This study characterized global treatment patterns and the clinical, psychosocial and economic burden of moderate‐to‐severe AD. Methods: MEASURE‐AD was a cross‐sectional 28‐country study in patients with physician‐confirmed moderate‐to‐severe AD who were either receiving or eligible for systemic therapy for AD. Patients ≥12 years were enrolled between December 2019 and December 2020 while attending routine office or clinic visit. Primary outcomes included Worst Pruritus Numeric Rating Scale (WP‐NRS; range: 0–10) and Dermatology Life Quality Index (DLQI; range: 0–30) and Children's DLQI (CDLQI; range: 0–30). Secondary outcomes included physician‐ and patient‐reported clinical, psychosocial and economic burden. Results: Of the 1591 patients enrolled, 1558 (1434 adults and 124 adolescents) fulfilled all patient selection criteria and were included in this analysis. Almost all patients (98.4%) in the total population were using AD medications and more than half (56%) were receiving systemic medication (15% systemic monotherapy). The most used systemic therapies were dupilumab (56.3%), systemic glucocorticoids (18.1%) and methotrexate (16.2%). Mean WP‐NRS was 5.3 in the total population, and most patients (≥55%) reported moderate‐to‐severe pruritus (WP‐NRS ≥4). Mean DLQI was 10.8 and mean CDLQI was 9.6. Secondary endpoints demonstrated substantial clinical, psychosocial, and economic burden of disease. Subgroup analysis demonstrated that patients receiving systemic therapy had lower disease burden than those not taking systemic medications. Conclusions: While systemic therapy lowers overall disease burden, patients with moderate‐to‐severe AD continue to have substantial multidimensional disease burden and uncontrolled disease. Overall, there is a need for effective disease management, including effective treatments that improve patients' psychosocial outcomes and reduce the economic burden of AD. [ABSTRACT FROM AUTHOR]

Background: Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by pruritic eczematous lesions. The effect of treatment withdrawal after response to upadacitinib oral treatment is not fully characterized. Objectives: Assess the effect of upadacitinib withdrawal on skin clearance and itch improvement in adult patients with moderate‐to‐severe AD and evaluate the kinetics of recovery on rescue treatment. Methods: Data from a phase 2b randomized, placebo‐controlled trial (NCT02925117) of upadacitinib in patients with moderate‐to‐severe AD were analysed. Patients were randomized 1:1:1:1 to receive upadacitinib 7.5 mg, 15 mg, 30 mg or placebo, and then at Week 16, patients were re‐randomized 1:1 to receive the same dose of upadacitinib (upadacitinib 30 mg for patients initialized to placebo) or placebo. From Week 20, those who experienced loss of response defined as Eczema Area and Severity Index <50% improvement from baseline (EASI 50) received rescue treatment with upadacitinib 30 mg. Results: Patients who withdrew from upadacitinib experienced a rapid loss of skin clearance response, while those who switched from placebo to upadacitinib gained response. Loss of skin clearance response occurred within 4 weeks and worsening of itch occurred within 5 days. In patients who originally received placebo or a lower dose of upadacitinib leading to a loss of EASI response, rescue treatment with upadacitinib 30 mg resulted in rapid recovery or improvement of both skin and itch responses; most patients who were re‐randomized to placebo achieved EASI 75 and IGA 0/1 by 8 weeks of rescue treatment. No new safety risks were observed. Conclusions: Continuous treatment with upadacitinib is suggested to maintain skin clearance and antipruritic effects. [ABSTRACT FROM AUTHOR]

Aims: First, population pharmacokinetic analyses were used to characterize upadacitinib pharmacokinetics in adolescent and adult participants with atopic dermatitis (AD) and to identify patient covariates that may impact upadacitinib pharmacokinetics. Second, the exposure‐response relationship for upadacitinib with efficacy and safety endpoints, and the effect of age and concomitant use of topical corticosteroids (TCS) on the exposure‐response relationship and dose selection for patients with AD were evaluated. Methods: A two‐compartment model with combined first‐ and zero‐order absorption adequately characterized the upadacitinib concentration‐time profiles in 911 healthy volunteer adolescent and adult participants with AD who received upadacitinib 15 or 30 mg orally once daily (QD) as monotherapy or in combination with TCS for 16 weeks. Logistic regression models were developed to characterize the exposure‐efficacy and safety relationships, and simulations were performed based on final exposure‐response models to predict efficacy responses in participants with AD who received placebo or upadacitinib as monotherapy or in combination with TCS. Results: Upadacitinib exposures were comparable between adolescents and adults. Mild or moderate renal impairment was predicted to increase the upadacitinib area under the plasma concentration‐time curve from time zero to 24 h after dosing (AUC24) approximately 12% and 25%, respectively, compared to participants with normal renal function. Female participants were predicted to have 20% higher AUC24 compared to male participants. Participants with AD were predicted to have 18% higher AUC24 compared to healthy participants. Simulated clinical efficacy responses showed added clinical efficacy benefit for all endpoints evaluated (8‐14%) with the upadacitinib 30 mg once‐daily regimen compared to 15 mg once‐daily in both age groups. In participants receiving upadacitinib in combination with TCS, significant exposure‐dependent increases in upadacitinib efficacy endpoints were observed. No significant effects of age or weight were identified in any of the exposure‐response models. Conclusion: The results of these analyses support the dose justification for upadacitinib in adult and adolescent patients with moderate to severe AD. [ABSTRACT FROM AUTHOR]

Characterization of upadacitinib use and switching from dupilumab to upadacitinib among patients with moderate-to-severe atopic dermatitis (AD) is needed. To evaluate the long-term safety and efficacy of continuous upadacitinib 30 mg and switching to upadacitinib after 24 weeks of dupilumab. Adults who completed the phase 3b clinical trial of oral upadacitinib 30 mg vs injectable dupilumab 300 mg (Heads Up) and entered a 52-week open-label extension (OLE) (NCT04195698) were included. All patients received 30-mg upadacitinib during the open-label period. We report results of a prespecified interim OLE 16-week analysis. Patients (n = 239) continuing upadacitinib maintained high levels of skin and itch response. Patients (n = 245) switching from dupilumab experienced additional incremental improvements in clinical responses within 4 weeks of starting upadacitinib. Most patients who did not achieve adequate clinical responses with dupilumab did so with upadacitinib. The safety profile of upadacitinib up to 40 weeks (week 16 of OLE) was consistent with previous phase 3 AD studies, with no new safety risks observed. Open-label study design. Clinical responses are maintained with continuous upadacitinib through 40 weeks and patients regardless of prior dupilumab response experienced improved outcomes when switched to upadacitinib. No new safety risks were observed. [ABSTRACT FROM AUTHOR]

Atopic dermatitis (AD) is a chronic, inflammatory skin disease characterized by intense itch and eczematous skin lesions that can impact individuals at any age across any area of the body. There is a need for safe treatments for AD that provide rapid itch relief and skin clearance and that are suitable for long-term use. Upadacitinib is a selective, reversible oral Janus kinase 1 (JAK1) inhibitor, which is approved in multiple countries for the treatment of adolescents and adults with moderate-to-severe AD. The current analysis assessed the long-term safety for up to 4 years of upadacitinib 15 and 30 mg in adolescents and adults with moderate-to-severe AD, using integrated data from three ongoing global pivotal phase 3 studies. The Measure Up 1, Measure Up 2, and AD Up studies are ongoing pivotal phase 3, randomized, placebo-controlled, multicenter studies evaluating the safety and efficacy of upadacitinib 15 mg and upadacitinib 30 mg in adolescents and adults with moderate-to-severe AD. Patients were randomized 1 : 1 : 1 to receive oral upadacitinib 15 mg, upadacitinib 30 mg or placebo once daily alone (Measure Up 1 and Measure Up 2) or with concomitant topical corticosteroids (AD Up). At Week 16, patients receiving upadacitinib 15 or 30 mg during the double-blinded period continued their assigned treatment in the blinded extension (BE) period, whereas patients receiving placebo were re-randomized 1 : 1 to receive either upadacitinib 15 or 30 mg in the BE period (upadacitinib treatment for up to 260 weeks). A total of 2693 adults and adolescents (upadacitinib 15 mg, 1340; upadacitinib 30 mg, 1353) who received at least one dose of upadacitinib were included in the integrated analysis. Treatment-emergent adverse events of special interest (AESI) were analysed as exposure-adjusted rates per 100 patient-years (PY) for the entire treatment period to adjust for potentially different durations of follow-up. Upadacitinib was well tolerated by both adults and adolescents. For all patients, rates of AESIs were similar at the 1-year analysis and up to 4-year analysis for upadacitinib (15 mg/30 mg) for: serious infections, 2.3 and 2.2/2.8 and 2.8; opportunistic infections, 1.6 and 1.8/1.9 and 2.4; active tuberculosis, <0.1/<0.1 at both time points; herpes zoster, 3.5 and 3.1/5.2 and 5.8; nonmelanoma skin cancer (NMSC), 0.3 and 0.4/0.4 and 0.3; malignancy excluding NMSC, 0.1 and 0.4/0.5 and 0.3; and adverse events leading to death, 0 and 0/<0.1 and <0.1. Rates of adjudicated major adverse cardiovascular events (MACE) were 0.1 and <0.1/<0.1 and <0.1, and for venous thromboembolic events (VTE) were <0.1 for both doses at the 1-year analysis and up to 4-year analysis. Rates of gastrointestinal perforations were 0 for both doses at both timepoint analyses. Rates of serious infections remain low (<3.0 E/100 PY). Based on the integrated analysis of long-term safety data for up to 4 years, rates of AESIs remained low throughout a longer duration of treatment with upadacitinib 15 or 30 mg among adults and adolescents with moderate-to-severe AD. No new safety risks were observed. Findings of the current safety analysis continue to support a favorable benefit-risk profile of upadacitinib in the treatment of adults and adolescents with moderate-to-severe AD for up to 4 years of treatment.

Background: Acne is the most frequent adverse event associated with upadacitinib treatment in patients with moderate-to-severe atopic dermatitis.Objective: To characterize the adverse event of acne associated with upadacitinib.Methods: This was a post hoc integrated analysis of 3 phase 3 randomized, double-blind, placebo-controlled trials of upadacitinib, alone (NCT03569293 and NCT03607422) or in combination with topical corticosteroids (NCT03568318). Data included were from the 16-week placebo-controlled period.Results: Over 16 weeks, 84 of 857 (9.8%), 131 of 864 (15.2%), and 19 of 862 (2.2%) patients randomized to receive upadacitinib 15 mg, upadacitinib 30 mg, and placebo, respectively, experienced acne. All cases of acne, except 1, were mild/moderate in severity; 2 patients discontinued treatment due to moderate acne. Acne occurred at higher rates among younger, female, and non-White patients. Acne required no intervention in 40.5% and 46.6% of patients receiving upadacitinib 15 and 30 mg, respectively; most remaining cases were managed with topical antibiotics, benzoyl peroxide, and/or retinoids. Acne also had no impact on patient-reported outcomes.Limitations: This study was relatively short in duration and had a small patient population.Conclusions: Acne associated with upadacitinib for atopic dermatitis treatment is usually mild/moderate in severity and managed with topical therapies or no intervention.

Introduction Network meta-analysis (NMA) provides useful information for medical decision makers via comprehensive indirect comparisons across therapies. As the targeted systemic therapy options for moderate-to-severe atopic dermatitis (AD) continue to grow, it is critical to update NMAs as well. Objectives: To assess the comparative efficacy of targeted systemic therapies with concomitant topical corticosteroids (TCS) in moderate-to-severe AD by including the latest Phase 3 combination therapy data for abrocitinib, lebrikizumab, and dupilumab in the NMA presented in Thyssen et al, 2021. Methods: Data from the Phase 3 combination therapy trial for lebrikizumab in moderate-to-severe AD (ADhere [NCT04250337]) as well as an additional abrocitinib-dupilumab head-to-head Phase 3 trial (JADE DARE [NCT04345367]) were included in the analyses along with other eligible trials for abrocitinib, baricitinib, dupilumab, tralokinumab, and upadacitinib identified through a systematic literature review in Thyssen et al., 2021. Outcomes included ≥90% and ≥75% improvement in Eczema Area and Severity Index (EASI 90, EASI 75) from baseline, ≥4-point improvement in Pruritus Numerical Rating Scale from baseline (ΔNRS ≥4), and Investigator Global Assessment (IGA) score of 0 or 1 (clear or almost clear) with a ≥2-point reduction from baseline (IGA 0/1), at the week 16 timepoint of each study. Bayesian NMA was performed with fixed and random effects models, with and without baseline risk-adjustment; fit statistics were assessed. Inconsistency was assessed via unrelated mean relative effects models. Odds ratio (OR), number needed to treat (NNT), placebo-unadjusted absolute response rate (ARR), and Surface Under the Cumulative RAnking curve (SUCRA) scores were estimated. Statistical significance was assessed by OR 95% credible intervals excluding 1. Results: The updated NMA analyzed 8 unique placebo-controlled trials and 1 active-controlled trial involving 4391 patients in 23 arms across 6 targeted therapies. Fit statistics supported fixed effects models across outcomes. All therapies were statistically more efficacious than placebo across all outcomes except baricitinib 2 mg for EASI-90. For EASI-90, upadacitinib 30 mg had the most favorable response estimates (ARR=63.2%, OR=11.3, NNT=2.0, SUCRA=98.3%), followed by abrocitinib 200 mg (ARR=55.8%, OR=8.3, NNT=2.4, SUCRA=90.0%), dupilumab 300 mg (ARR=44.8%, OR=5.3, NNT=3.2, SUCRA=68.3%), abrocitinib 100 mg (ARR=44.0%, OR=5.2, NNT=3.3, SUCRA=65.8%), upadacitinib 15 mg (ARR=42.9%, OR=4.9, NNT=3.4, SUCRA=64.3%), and the newly added lebrikizumab 250 mg (ARR=28.9%, OR=2.7, NNT=6.6, SUCRA=39.9%). The rank order for EASI-75 was similar (upadacitinib 30 mg [ARR=78.3%, OR=9.5, NNT=2.0, SUCRA=98.5%], abrocitinib 200 mg [ARR=73.0%, OR=7.1, NNT=2.3, SUCRA=89.1%], upadacitinib 15 mg [ARR=66.1%, OR=5.1, NNT=2.7, SUCRA=71.0%], dupilumab 300 mg [ARR=65.3%, OR=5.0, NNT=2.7, SUCRA=69.2%], abrocitinib 100 mg [ARR=60.3%, OR=4.0, NNT=3.2, SUCRA=54.0%], and lebrikizumab 250 mg [ARR=54.5%, OR=3.1, NNT=3.8, SUCRA=41.2%]). For ΔNRS ≥4, upadacitinib 30 mg had the most favorable response (ARR=68.9%, OR=10.0, NNT=2.1, SUCRA=99.9%), followed by upadacitinib 15 mg (ARR=56.6%, OR=5.9, NNT=2.7, SUCRA=84.0%), abrocitinib 200 mg (ARR=51.6%, OR=4.8, NNT=3.1, SUCRA=75.6%), dupilumab 300 mg (ARR=49.3%, OR=4.4, NNT=3.3, SUCRA=67.0%), baricitinib 4 mg (ARR=44.4%, OR=3.6, NNT=4.0, SUCRA=57.7%), and abrocitinib 100 mg (ARR=35.9%, OR=2.5, NNT=5.9, SUCRA=36.1%); lebrikizumab 250 mg ranked eighth (ARR=33.4%, OR=2.3, NNT=7.0, SUCRA=31.3%). For IGA 0/1, upadacitinib 30 mg (ARR=66.5%, OR=11.7, NNT=2.0, SUCRA=99.6%) had the most favorable estimates, followed by abrocitinib 200 mg (ARR=53.5%, OR=6.8, NNT=2.6, SUCRA=86.6%), upadacitinib 15 mg (ARR=48.0%, OR=5.4, NNT=3.0, SUCRA=76.2%), dupilumab 300 mg (ARR=42.1%, OR=4.3, NNT=3.7, SUCRA=64.7%), abrocitinib 100 mg (ARR=39.1%, OR=3.8, NNT=4.1, SUCRA=56.1%), and baricitinib 4 mg (ARR=30.6%, OR=2.6, NNT=6.4, SUCRA=39.9%); lebrikizumab 250 mg ranked seventh (ARR=29.2%, OR=2.4, NNT=7.0, SUCRA=35.8%). Baricitinib 2 mg and tralokinumab 300 mg were generally ranked lower across outcomes. Conclusions: Among targeted therapies for moderate-to-severe AD used with concomitant TCS for 16 weeks, upadacitinib 30 mg remained the most efficacious therapy in this NMA, generally followed by abrocitinib 200 mg, upadacitinib 15 mg or dupilumab 300 mg, abrocitinib 100 mg, and baricitinib 4 mg or lebrikizumab 250 mg.

Background: Systemic therapies are typically combined with topical corticosteroids for the management of moderate-to-severe atopic dermatitis. Upadacitinib is an oral Janus kinase (JAK) inhibitor with greater inhibitory potency for JAK1 than JAK2, JAK3, or tyrosine kinase 2 that is being tested for atopic dermatitis. We aimed to assess the efficacy and safety of upadacitinib plus topical corticosteroids compared with placebo for the treatment of moderate-to-severe atopic dermatitis.Methods: In this randomised, double-blind, placebo-controlled, phase 3 trial (AD Up) adults (aged 18-75 years) and adolescents (aged 12-17 years) with chronic atopic dermatitis that was moderate to severe (≥10% of body surface area affected, Eczema Area and Severity Index [EASI] score of ≥16, validated Investigator's Global Assessment for atopic dermatitis [vIGA-AD] score of ≥3, and weekly average Worst Pruritus Numerical Rating Scale score of ≥4 at baseline) were enrolled at 171 clinical centres across 22 countries in the Asia-Pacific region, Europe, the Middle East, North America, and Oceania. Patients were randomly assigned (1:1:1) to receive upadacitinib 15 mg, upadacitinib 30 mg, or placebo once daily, all in combination with topical corticosteroids for 16 weeks. Randomisation was done using an interactive response technology system, stratified by baseline disease severity, geographical region, and age. Study investigators, study site personnel, and patients were masked to study treatment. The coprimary endpoints were the proportion of patients who had achieved at least a 75% reduction 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 improvement from baseline) at week 16. Efficacy was analysed in the intention-to-treat population and safety was analysed in all patients who received at least one dose of study drug. This study is registered with ClinicalTrials.gov, NCT03568318, and is active, but not recruiting.Findings: Between Aug 9, 2018, and Dec 20, 2019, 901 patients were randomly assigned to receive upadacitinib 15 mg plus topical corticosteroids (n=300), upadacitinib 30 mg plus topical corticosteroids (n=297), or placebo plus topical corticosteroids (n=304). At week 16, the proportion of patients who had achieved EASI-75 was significantly higher in the upadacitinib 15 mg plus topical corticosteroid group (194 [65%] of 300 patients) and the upadacitinib 30 mg plus topical corticosteroids group (229 [77%] of 297 patients) than the placebo group (80 [26%] of 304 patients; adjusted difference in EASI-75 response rate vs placebo, 38·1% [95% CI 30·8-45·4] for the upadacitinib 15 mg group and 50·6% [43·8-57·4] for the upadacitinib 30 mg group; p<0·0001 for both doses). The proportion of patients who had achieved a vIGA-AD response at week 16 was significantly higher in the upadacitinib 15 mg plus topical corticosteroid group (119 [40%] patients) and upadacitinib 30 mg plus topical corticosteroid group (174 [59%] patients) than the placebo group (33 [11%] patients; adjusted difference in vIGA-AD response vs placebo, 28·5% [22·1-34·9] for the upadacitinib 15 mg group and 47·6% [41·1-54·0] for the upadacitinib 30 mg group; p<0·0001 for both doses). During the double-blind period, upadacitinib 15 and 30 mg were well tolerated in combination with topical corticosteroids. The most frequently reported treatment-emergent adverse events (≥5% in any treatment group) were acne, nasopharyngitis, upper respiratory tract infection, oral herpes, elevation of blood creatine phosphokinase levels, headache, and atopic dermatitis. The incidence of acne was higher in the upadacitinib 15 mg (30 [10%] of 300 patients) and upadacitinib 30 mg (41 [14%] of 297 patients) groups than the placebo group (six [2%] of 304 patients). The incidence of adverse events leading to discontinuation of study drug (four [1%] patients in the upadacitinib 15 mg plus topical corticosteroids group, four [1%] patients in the upadacitinib 30 mg plus topical corticosteroids group, and seven [2%] patients in the placebo plus topical corticosteroids group) and serious adverse events (seven [2%] patients, four [1%] patients, and nine [3%] patients) were similar among treatment groups. No deaths were reported in any treatment group.Interpretation: Upadacitinib plus topical corticosteroids was well tolerated and superior to placebo plus topical corticosteroids. Upadacitinib as combination therapy had a positive benefit-risk profile in adults and adolescents with moderate-to-severe atopic dermatitis.Funding: AbbVie. [ABSTRACT FROM AUTHOR]

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.

Upadacitinib is a selective Janus kinase 1 inhibitor that was recently approved for treatment of rheumatoid arthritis and is currently being evaluated for treatment of several other autoimmune diseases, including atopic dermatitis (AD). The relationships between upadacitinib plasma exposure and efficacy (assessed as Eczema Area Severity Index [EASI]‐75, EASI‐90, and Investigator Global Assessment [IGA] 0/1) in subjects with moderate to severe atopic dermatitis were characterized using the data from 167 subjects who were enrolled in a phase 2b dose‐ranging study. Subjects were randomized to receive once daily doses of monotherapy treatment with upadacitinib extended‐release 7.5, 15, or 30 mg or placebo for 16 weeks. Logistic regression models were developed and utilized to simulate efficacy for upadacitinib with an approximate phase 3 sample size. Based on exposure‐response models, 15 mg once daily is predicted to achieve EASI‐75, EASI‐90, and IGA 0/1 responses in 48%, 26%, and 29% of subjects, respectively, compared with placebo responses of 9%, 2%, and 2%, respectively, whereas 30 mg once daily is predicted to provide an additional approximately 20% greater efficacy for these end points relative to 15 mg once daily. These analyses supported the selection of upadacitinib doses that are being evaluated in ongoing global phase 3 studies in atopic dermatitis. [ABSTRACT FROM AUTHOR]

Atopic dermatitis is a chronic inflammatory skin disease characterized by pruritic skin lesions. We sought to evaluate the safety and efficacy of multiple doses of the selective Janus kinase 1 inhibitor upadacitinib in patients with moderate to severe atopic dermatitis. In the 16-week, double-blind, placebo-controlled, parallel-group, dose-ranging portion of this 88-week trial in 8 countries (ClinicalTrials.gov , NCT02925117 ; ongoing, not recruiting), adults with moderate to severe disease and inadequate control by topical treatment were randomized 1:1:1:1, using an interactive response system and stratified geographically, to once-daily upadacitinib oral monotherapy 7.5, 15, or 30 mg or placebo. The primary end point was percentage improvement in Eczema Area and Severity Index from baseline at week 16. Efficacy was analyzed by intention-to-treat in all randomized patients. Safety was analyzed in all randomized patients who received study medication, based on actual treatment. Patients (N = 167) enrolled from November 21, 2016, to April 20, 2017. All were randomized and analyzed for efficacy (each upadacitinib group, n = 42; placebo, n = 41); 166 were analyzed for safety (each upadacitinib group, n = 42; placebo, n = 40). The mean (SE) primary efficacy end point was 39% (6.2%), 62% (6.1%), and 74% (6.1%) for the upadacitinib 7.5-, 15-, and 30-mg groups, respectively, versus 23% (6.4%) for placebo (P =.03, <.001, and <.001). Serious adverse events occurred in 4.8% (2 of 42), 2.4% (1 of 42), and 0% (0 of 42) of upadacitinib groups (vs 2.5% [1 of 40] for placebo). A dose-response relationship was observed for upadacitinib efficacy; the 30-mg once-daily dose showed the greatest clinical benefit. Dose-limiting toxicity was not observed. [ABSTRACT FROM AUTHOR]

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.

Atopic dermatitis (AD) is characterized by intense itch and symptoms that adversely impact quality of life (QoL). Upadacitinib is a selective Janus kinase-1 inhibitor approved for moderate-to-severe AD. We assessed the effect of once daily oral upadacitinib (15 or 30 mg), with or without concurrent topical corticosteroid treatment, on patient-reported outcomes for adults and adolescents with moderate-to-severe atopic dermatitis during the double-blind, placebo-controlled phase 3 clinical trials, Measure Up 1 (NCT03569293), Measure Up 2 (NCT03607422) and AD Up (NCT03568318). Assessments included itch (Worst Pruritus Numerical Rating Scale), skin pain and symptom severity (AD Symptom Scale), symptom frequency (Patient Oriented Eczema Measure) and sleep, daily activities and emotional state (AD Impact Scale). Post hoc analysis of 2240 adults and 344 adolescents randomized patients was performed. By Week 2, more patients receiving upadacitinib achieved a clinically relevant response in itch, skin pain, symptom severity, symptom frequency, sleep, daily activities and emotional state vs. placebo across studies among adults (upadacitinib 15 mg: 30.8–87.3%; upadacitinib 30 mg: 38.0–89.9%; placebo: 2.1–43.1%; nominal P < 0.001 for all comparisons) and adolescents (upadacitinib 15 mg: 19.4–82.9%; upadacitinib 30 mg: 35.3–97.6%; placebo: 0–41.0%; nominal P < 0.05 for 37/42 comparisons). These trends continued through week 16 where response rates for all outcomes improved with upadacitinib vs. placebo in adults (upadacitinib 15 mg: 42.9–80.4%; upadacitinib 30 mg: 60.9–84.6%; placebo: 10.1–38.1%; nominal P < 0.001 for all comparisons) and adolescents (upadacitinib 15 mg: 33.3–78.0%; upadacitinib 30 mg: 50.0–85.7%; placebo: 2.8–43.6%; nominal P < 0.05 for 41/42 comparisons). These findings highlight the rapid, sustained efficacy of once daily oral upadacitinib in improving symptom burden and QoL in adults and adolescents with moderate-to-severe AD.

The landscape of targeted systemic treatments for moderate-to-severe atopic dermatitis (AD) continues to expand. With limited head-to-head randomized controlled trials conducted in AD, a network meta-analysis (NMA) helps inform treatment decisions by providing indirect comparisons across therapies. This study aims to update an NMA presented in Silverberg et al. (2022), assessing the comparative efficacy of targeted systemic treatments without concomitant topical corticosteroids in moderate-to-severe AD by including the latest Phase 3 monotherapy data for lebrikizumab. Data from the two most recently published Phase 3 monotherapy trials for lebrikizumab in moderate-to-severe AD [ADvocate1 (NCT04146363); ADvocate2 (NCT04178967)] were included in the analyses along with other eligible Phase 3 or 4 randomized placebo-controlled trials for abrocitinib, baricitinib, dupilumab, tralokinumab and upadacitinib identified through a systemic literature review in Silverberg et al. (2022). Prespecified efficacy outcomes included ≥90% and ≥75% improvement in Eczema Area and Severity Index (EASI 90, EASI 75) from baseline, ≥4-point improvement in Pruritus Numerical Rating Scale from baseline (ΔNRS ≥4) and Investigator Global Assessment (IGA) score of 0 or 1 (clear or almost clear) with a ≥2-point reduction from baseline (IGA 0/1), at the primary endpoint timepoint for each study (Week 12 for abrocitinib, Week 16 for all other therapies). Bayesian NMA was performed with fixed-effect, random-effect and baseline risk-adjusted models; fit statistics and diagnostics were assessed. The odds ratio (OR), number needed to treat (NNT), placebo-unadjusted absolute response rate (ARR) and Surface Under the Cumulative RAnking curve (SUCRA) scores were estimated. Statistical significance was assessed by OR 95% credible intervals excluding 1. The updated NMA analysed 13 unique placebo-controlled trials involving 7105 patients in 32 arms across six targeted therapies. Fit statistics and diagnostics supported fixed-effect models for all outcomes analysed. All targeted therapies had significantly greater response rates compared with placebo across all outcomes. For EASI 90, upadacitinib 30 mg had the most favorable response estimates (ARR = 58.3%, OR = 23.1, NNT = 1.9, SUCRA = 98.5%), followed by abrocitinib 200 mg (ARR = 45.2%, OR = 13.5, NNT = 2.5, SUCRA = 84.3%), upadacitinib 15 mg (ARR = 43.7%, OR = 12.8, NNT = 2.6, SUCRA = 82.0%), dupilumab 300 mg (ARR = 27.3%, OR = 6.2, NNT = 4.7, SUCRA = 52.8%), abrocitinib 100 mg (ARR = 26.8%, OR = 6.0, NNT = 4.8, SUCRA = 48.4%), baricitinib 4 mg (ARR = 25.0%, OR = 5.5, NNT = 5.2, SUCRA = 45.5%) and lebrikizumab 250 mg (ARR = 23.6%, OR = 5.1, NNT = 5.6, SUCRA = 40.0%). A similar rank order was observed for EASI 75 [upadacitinib 30 mg (ARR = 72.3%, OR = 19.1, NNT = 1.7, SUCRA = 98.5%), abrocitinib 200 mg (ARR = 64.6%, OR = 13.3, NNT = 1.9, SUCRA = 87.3%), upadacitinib 15 mg (ARR = 59.8%, OR = 10.9, NNT = 2.1, SUCRA = 80.2%), dupilumab 300 mg (ARR = 45.3%, OR = 6.0, NNT = 3.0, SUCRA = 55.4%), abrocitinib 100 mg (ARR = 44.9%, OR = 5.9, NNT = 3.1, SUCRA = 53.5%) and lebrikizumab 250 mg (ARR = 44.7%, OR = 5.9, NNT = 3.1, SUCRA = 53.9%)]. For ΔNRS ≥4, upadacitinib 30 mg also had the most favorable response (ARR = 56.1%, OR = 12.9, NNT = 2.1, SUCRA = 99.0%), followed by abrocitinib 200 mg (ARR = 45.4%, OR = 8.3, NNT = 2.8, SUCRA = 83.6%), upadacitinib 15 mg (ARR = 42.9%, OR = 7.6, NNT = 3.0, SUCRA = 79.2%), dupilumab 300 mg (ARR = 33.9%, OR = 5.2, NNT = 4.0, SUCRA = 54.2%), lebrikizumab 250 mg (ARR = 33.9%, OR = 5.1, NNT = 4.1, SUCRA = 54.1%) and abrocitinib 100 mg (ARR = 31.5%, OR = 4.6, NNT = 4.5, SUCRA = 46.1%). For IGA 0/1, upadacitinib 30 mg (ARR = 61.8%, OR = 19.4, NNT = 1.9, SUCRA = 99.9%) and upadacitinib 15 mg (ARR = 48.1%, OR = 11.1, NNT = 2.5, SUCRA = 86.9%) had the most favorable estimates, followed by abrocitinib 200 mg (ARR = 39.3%, OR = 7.7, NNT = 3.2, SUCRA = 75.5%), dupilumab 300 mg (ARR = 32.4%, OR = 5.7, NNT = 4.1, SUCRA = 62.1%) and lebrikizumab 250 mg (ARR = 28.0%, OR = 4.7, NNT = 5.0, SUCRA = 49.1%). Baricitinib 2 mg and tralokinumab 300 mg were generally ranked lower across outcomes. Among targeted treatments for moderate-to-severe AD used without concomitant topical corticosteroids for 12–16 weeks, upadacitinib 30 mg remains the most efficacious therapy in this NMA, generally followed by abrocitinib 200 mg, upadacitinib 15 mg, dupilumab 300 mg and lebrikizumab 250 mg or abrocitinib 100 mg.

Objectives: Atopic dermatitis (AD) is a chronic, relapsing skin condition, with signs and symptoms that impact patients' lives and are best measured from the patient perspective. Therefore, there is a need for AD-specific questionnaires that are consistent with Food and Drug Administration guidance and best measurement practices, assessing sign and symptom severity and associated impacts, to support treatment efficacy in regulated trials. The objectives were to develop patient-reported outcome (PRO) questionnaires assessing sign and symptom severity, as well as impacts of moderate-to-severe adult AD. Methods: A targeted literature review and meetings with clinical experts (dermatologists) were conducted to identify AD-related sign, symptom, and impact concepts. Results were harmonized and used to construct two draft PRO questionnaires: the Atopic Dermatitis Symptom Scale (ADerm-SS; 11 items) and the Atopic Dermatitis Impact Scale (ADerm-IS; 10 items). The content validity and questionnaire content were evaluated via qualitative concept elicitation/cognitive debriefing interviews with adult patients with moderate-to-severe AD. Results: From the literature (n = 13 articles), 13 sign and symptom and 43 impact concepts were identified, while 21 sign and symptom and 48 impacts were elicited from experts (n = 3). During the patient interviews (n = 15), 19 sign and symptom and 41 impact concepts were reported, the majority of which were evaluated by the ADerm-SS and ADerm-IS, thus substantiating the content of both questionnaires. Additionally, patients interpreted both questionnaires as intended by the developers. Conclusions: The ADerm-SS and ADerm-IS can be regarded as content-valid PRO questionnaires for moderate-to-severe AD. [ABSTRACT FROM AUTHOR]
