Abstract
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.

Abstract
BACKGROUND Pain is a frequent symptom of atopic dermatitis (AD). OBJECTIVES The aims of the study were to evaluate the effects of dupilumab on pain/discomfort in AD and to determine whether pain correlates with other outcomes. METHODS This was a post hoc analysis of 5 randomized, placebo-controlled clinical trials in which adults with chronic AD received placebo or dupilumab 300 mg every 2 weeks or once weekly with and without topical corticosteroids. Proportions of patients with no pain/discomfort on this dimension of the 5-dimension EuroQoL (EQ-5D) at week 16 (all trials) and week 52 (CHRONOS) were compared between placebo and dupilumab. Correlations were evaluated between pain/discomfort and signs and symptoms of AD. RESULTS Among 2632 evaluated patients, 72.9% to 83.1% reported at least moderate pain/discomfort at baseline. Higher proportions treated with dupilumab reported no pain/discomfort at week 16 relative to placebo; risk differences ranged from 22.3% (95% confidence interval = 11.5%-33.1%) to 42.2% (95% confidence interval = 26.6%-57.8%, all P ≤ 0.0001), with similar effects observed at week 52. Correlations at baseline of pain/discomfort with signs and symptoms of AD were low to moderate. CONCLUSIONS Pain/discomfort, present in a substantial proportion of patients with moderate-to-severe AD, was significantly reduced by dupilumab treatment. Given the low-to-moderate correlations with other AD symptoms at baseline, pain likely represents a distinct AD symptom.Trial Registration: ClinicalTrials.gov identifiers NCT01859988, NCT02277743, NCT02277769, NCT02260986, and NCT02755649.

Abstract
BACKGROUND Pivotal phase III studies demonstrated that abrocitinib, an oral, once-daily, JAK1-selective inhibitor, is effective treatment for moderate-to-severe atopic dermatitis (AD) as monotherapy and in combination with topical therapy. OBJECTIVE The aim of this study was to evaluate the long-term safety of abrocitinib 200 mg and 100 mg in an integrated analysis of a phase IIb study, four phase III studies, and one long-term extension study. METHODS Two cohorts were analyzed: a placebo-controlled cohort from 12- to 16-week studies and an all-abrocitinib cohort including patients who received one or more abrocitinib doses. Adverse events (AEs) of interest and laboratory data are reported. RESULTS Total exposure in the all-abrocitinib cohort (n = 2856) was 1614 patient-years (PY); exposure was ≥ 24 weeks in 1248 patients and ≥ 48 weeks in 606 (maximum 108 weeks). In the placebo-controlled cohort (n = 1540), dose-related AEs (200 mg, 100 mg, placebo) were nausea (14.6%, 6.1%, 2.0%), headache (7.8%, 5.9%, 3.5%), and acne (4.7%, 1.6%, 0%). Platelet count was reduced transiently in a dose-dependent manner; 2/2718 patients (200-mg group) had confirmed platelet counts of < 50 × 103/mm3 at week 4. Incidence rates (IRs) were 2.33/100PY and 2.65/100 PY for serious infection, 4.34/100PY and 2.04/100PY for herpes zoster, and 11.83/100PY and 8.73/100PY for herpes simplex in the 200-mg and 100-mg groups, respectively. IRs for nonmelanoma skin cancer, other malignancies, and major adverse cardiovascular events were < 0.5/100PY for both doses. Five venous thromboembolism events occurred (IR 0.30/100PY), all in the 200-mg group. There were three deaths due to gastric carcinoma (diagnosed at day 43), sudden death, and COVID-19. CONCLUSION Abrocitinib, with proper patient and dose selection, has a manageable tolerability and longer-term safety profile appropriate for long-term use in patients with moderate-to-severe AD.

Abstract
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.

Abstract
Psoriasis, a chronic immune-mediated disease, is associated with an increased risk of cardiovascular events and mortality. Secukinumab selectively neutralizes IL-17A and has reported high efficacy with a favorable safety profile in various psoriatic disease manifestations. Subsequent to the 12-week randomized, placebo-controlled, double-blind treatment period, patients with moderate-to-severe psoriasis received secukinumab for 40 weeks. Vascular inflammation using 18F-2-fluorodeoxyglucose-positron emission tomography/computed tomography imaging and blood-based cardiometabolic was assessed at week 0, 12, and 52. The difference in change in aortic inflammation from baseline to week 12 for secukinumab (n = 46) versus placebo (n = 45) was -0.053 (95% confidence interval = -0.169 to 0.064; P= 0.37). Small increases in total cholesterol, low-density lipoprotein, and low-density lipoprotein particles, but no changes in markers of inflammation, adiposity, insulin resistance, or predictors of diabetes, were observed with secukinumab treatment compared with placebo. At week 52, reductions in TNF-α (P= 0.0063) and ferritin (P= 0.0354), and an increase in fetuin-A (P= 0.0024), were observed with secukinumab treatment compared with baseline. No significant changes in aortic inflammation or markers of advanced lipoprotein characterization, adiposity, or insulin resistance were observed with secukinumab treatment compared with baseline. Secukinumab exhibited a neutral impact on aortic vascular inflammation and biomarkers of cardiometabolic disease after 52 weeks of treatment.

Abstract
BACKGROUND Skin barrier dysfunction may precede infantile development of clinical atopic dermatitis (AD). Early-life emollient therapy to enhance barrier function may prevent or modify AD development in high-risk infants. OBJECTIVES (a) To determine whether daily full-body application of an emollient with ceramide and amino acids (study emollient) can reduce the cumulative AD incidence compared to standard skin care at 1 year of age. (b) To evaluate the study emollient's effect on skin barrier function, natural moisturizing factor and the microbiome using non-invasive biophysical and biochemical techniques. METHODS We performed a single-centre, investigator-blinded, randomized controlled trial enrolling infants at high risk for AD development determined by family history. The intervention was full-body once-daily application of the study emollient. The control arm was asked to not apply full-body emollient regularly and only use an emollient of their choice for dry skin. The primary outcome was the cumulative incidence of AD diagnosed at 12 months by a blinded investigator. RESULTS Less than half the target sample size was enrolled (n = 100, goal sample was 208) with 28% lost to follow-up. Across all clinical end points, a numerical trend was observed in favour of the intervention, although not statistically significant likely due to lack of power from under-enrolment. AD was diagnosed in 13.2% vs. 25.0% at 12 months (P = 0.204) and 19.4% vs. 31.0% at 2 years (P = 0.296) in intervention vs. control groups, respectively. There were no significant differences between groups in skin barrier or microbiome assessments. While there were no serious adverse events, there were more cases of reported contact dermatitis in the intervention vs. control arms, 9.3% vs. 4.3%, respectively; however, these events were not related to the study emollient and most mild in severity. CONCLUSION The observed trends suggest a protective effect of daily study emollient therapy compared to control.

Plain language summary
Atopic dermatitis (AD) is a type of eczema common in babies and young children. Poor function of the skin barrier is thought to lead to changes in the composition of bacteria found on the skin. This small study investigated the effects of daily use of an emollient, Cetaphil Moisturising Cream, on the barrier function and bacterial communities on the skin of infants at risk of developing AD. After 6 months, the emollient group had a lower skin pH than the control group. The group using the emollient had more diverse skin bacterial communities than the control group. The proportion of Streptococcus salivarius was higher in the emollient versus control groups. The authors concluded that lower skin pH and increased skin bacterial diversity after long-term emollient use may reduce inflammation and lower the risk of infants developing AD.
Abstract
BACKGROUND Emollients are a mainstay of treatment in atopic dermatitis (AD), a disease distinguished by skin bacterial dysbiosis. However, changes in skin microbiota when emollients are used as a potential AD preventative measure in infants remain incompletely characterized. RESULTS We compared skin barrier parameters, AD development, and bacterial 16S ribosomal RNA gene sequences of cheek, dorsal and volar forearm samples from 6-month-old infants with a family history of atopy randomized to receive emollients (n = 11) or no emollients (controls, n = 12). The emollient group had a lower skin pH than the control group. The number of bacterial taxa in the emollient group was higher than in the control group at all sites. The Streptococcus salivarius proportion was higher in the emollient versus control groups at all sites. S. salivarius proportion appeared higher in infants without AD compared to infants with AD. A decrease in S. salivarius abundance was further identified in a separate larger population of older children demonstrating an inverse correlation between AD severity at sampling sites and S. salivarius proportions. CONCLUSIONS The decreased skin pH and the increased proportion of S. salivarius after long-term emollient use in infants at risk for developing AD may contribute to the preventative effects of emollients in high-risk infants.

Abstract
Patients with atopic dermatitis (AD) are commonly colonized with Staphylococcus aureus (AD S. aureus+), but what differentiates this group from noncolonized AD patients (AD S. aureus-) has not been well studied. To evaluate whether these two groups have unique phenotypic or endotypic features, we performed a multicenter, cross-sectional study enrolling AD S. aureus+ (n = 51) and AD S. aureus- (n = 45) participants defined by the presence or absence of S. aureus by routine culture techniques and nonatopic, noncolonized control individuals (NA S. aureus-) (n = 46). Filaggrin (FLG) genotypes were determined, and disease severity (Eczema Area and Severity Index, Rajka-Langeland Severity Score, Investigator's Global Assessment score, Numerical Rating Scale, and Dermatology Life Quality Index) was captured. Skin physiology was assessed (transepidermal water loss [TEWL], stratum corneum integrity, hydration, and pH), and serum biomarkers were also measured. We found that AD S. aureus+ patients had more severe disease based on all scoring systems except itch (Numerical Rating Scale), and they had higher levels of type 2 biomarkers (eosinophil count, tIgE, CCL17, and periostin). Additionally, AD S. aureus+ patients had significantly greater allergen sensitization (Phadiatop and tIgE), barrier dysfunction (TEWL and stratum corneum integrity), and serum lactate dehydrogenase (LDH) than both the AD S. aureus- and NA S. aureus- groups. FLG mutations did not associate with S. aureus+ colonization. In conclusion, adult patients with AD who are colonized on their skin with S. aureus have more severe disease, greater type 2 immune deviation, allergen sensitization, barrier disruption, and LDH level elevation than noncolonized patients with AD.

Abstract
BACKGROUND Eczema prevention is now an active area of dermatologic and allergy research. Defining an incident case is therefore a prerequisite for such a study. OBJECTIVE We sought to examine how an incident case of atopic dermatitis was defined in previous atopic dermatitis prevention studies in order to make recommendations on a standard definition of new atopic dermatitis cases for use in future prevention trials. METHODS We conducted a systematic review of controlled interventional atopic dermatitis prevention studies by using searches of MEDLINE and Cochrane databases for studies published from 1980 to the end of January 2011. Studies that included atopic dermatitis as a secondary outcome, such as asthma prevention trials, were included. RESULTS One hundred two studies were included in the final analysis, of which 27 (26.5%) did not describe any criteria for defining an incident case of atopic dermatitis. Of the remaining 75 studies with reported disease criteria, the Hanifin-Rajka criteria were the most commonly used (28 studies). A disease definition unique to that particular study (21 studies) was the second most commonly used disease definition, although the sources for such novel definitions were not cited. CONCLUSIONS The results from this systematic review highlight the need for improved reporting and standardization of the definition used for an incident case in atopic dermatitis prevention studies. Most prevention studies have used disease definitions such as the Hanifin-Rajka criteria that include disease chronicity. While acceptable for cumulative incidence outcomes, inclusion of disease chronicity precludes the precise measurement of disease onset. We propose a definition based on existing scientific studies that could be used in future prospective studies.
