Introduction/Background Targeting and binding OX40 ligand (OX40L) expressed on antigen-presenting cells may inhibit the persistent immune response that drives atopic dermatitis (AD) pathophysiology. Amlitelimab (SAR445229; KY1005) is a potential first-in-class, fully human, non-depleting anti-OX40L monoclonal antibody that blocks OX40L-OX40 interactions and has shown efficacy and an acceptable safety profile in a Phase 2a trial in adults with moderate-to-severe AD. Here, we present 24-week efficacy and safety results (Part 1) from an ongoing dose-ranging Phase 2b trial. The study remains blinded to individual patient data (Part 2 ongoing). Objectives: To evaluate the efficacy and safety of amlitelimab in adults with moderate-to-severe AD. Methods: STREAM-AD (NCT05131477) is a 52-week, randomised, double-blinded, placebo-controlled Phase 2b monotherapy trial. This study is designed with 2 parts (double-blind throughout): a 24-week treatment period (Part 1, completed and presented here) and a 36-week maintenance/withdrawal period (Part 2, ongoing). Adults (18 to <75 years; n=390) with moderate-to-severe AD were randomised 1:1:1:1:1 to receive subcutaneous amlitelimab Q4W (250 mg with 500 mg loading dose [LD], n=77; 250 mg without LD, n=78; 125 mg without LD, n=77; or 62.5 mg without LD, n=79) or placebo Q4W (n=79). The primary endpoint was percentage change in Eczema Area and Severity Index (EASI) from baseline at Week 16. Key secondary endpoints included percentage change in EASI at Week 24 and percentage of patients with at least 75% reduction from baseline in EASI (EASI-75), percentage of patients with Investigator Global Assessment response of 0 (clear) or 1 (almost clear) and a reduction from baseline of ≥2 points (IGA 0/1), and proportion of patients with a weekly average reduction of Peak Pruritus Numerical Rating Scale (PP-NRS) ≥4 points from baseline. The primary efficacy analysis included all randomised patients who completed Week 24 or discontinued treatment or study prior to Week 24 visit (n=390), whereas the safety analysis included all treated patients (n=388). Results: Treatment with amlitelimab resulted in statistically significant improvements in percentage change in EASI from baseline to Week 16 compared to placebo for all four doses studied. The 250 mg with LD group had the numerically highest response versus placebo at Week 16, with a least-squares mean change from baseline of -32.1% (95% CI: -43.9, -20.3; P<0.0001); the remaining groups without LD had the following responses versus placebo: 250 mg, -27.3 (95% CI: -39.1, -15.6; P<0.0001); 125 mg, -22.2 (95% CI: -34.0, -10.4; P=0.0002); and 62.5 mg, -30.2 (95% CI: -41.9, -18.5; P<0.0001). There were also clinically meaningful improvements in all key secondary efficacy outcome measures, with all amlitelimab dose groups demonstrating nominally significant (P<0.05) efficacy versus placebo for EASI-75, IGA 0/1, and PP-NRS =4, except 250 mg (no LD) in IGA 0/1 at Week 16 (P=0.0562). Continued improvements were generally observed through Week 24 in primary and key secondary efficacy outcomes. Amlitelimab was well tolerated across all dose groups, with no safety concerns identified. Conclusions: In this dose-ranging Phase 2b trial of amlitelimab in adults with moderate-to-severe AD, amlitelimab demonstrated clinically meaningful efficacy over 24 weeks with an acceptable safety profile across all four dose groups.

Background Amlitelimab is a fully-human, non-depleting, anti-OX40 ligand (OX40L) monoclonal antibody that binds to OX40L on antigen-presenting cells. Amlitelimab blocks the interaction of OX40L with OX40 on activated T-cells, inhibiting T-cell dependent inflammation without depleting T-cells. Objective To evaluate the efficacy and safety of amlitelimab (Part 1), and explore the maintenance of clinical response over a 28-Week period (Part 2) in patients with moderate-to-severe AD. Methods STREAM-AD (NCT05131477), was a randomized, double-blind, placebo-controlled Phase 2b trial, that included a 24-Week, double-blind, treatment period (Part 1), a 28-Week maintenance/withdrawal period (Part 2), and a 16-Week safety follow-up. In Part 1, adult participants were randomized 1:1:1:1:1 to subcutaneous amlitelimab Q4W (250mg with 500mg loading dose [+ LD], n=77; 250mg, n=78; 125mg, n=77; 62.5mg, n=79) or placebo Q4W (n=79). In Part 2, Clinical responders (defined as those achieving EASI-75 and/or IGA 0/1 at Week-24) in Part 1, were rerandomized 3:1 to withdraw or continue pre-Week 24 Q4W dose (250mg + LD, n=34 [withdrawal]/n=13 [continuing]; 250mg, n=28/n=12; 125mg, n=33/n=12; 62.5mg, n=35/n=7; placebo responders continuing placebo, n=16), and were followed to Week-52 to evaluate maintenance of clinical response. Primary efficacy endpoint was percent change in EASI from baseline at Week-16. Key secondary endpoints were proportion of patients achieving IGA 0/1, EASI-75, PP-RNS≥4. The statistical analysis was performed using two methods: 1) imputing the endpoint as nonresponder after rescue medication use (NRI); and 2) including all measurements regardless of rescue use (treatment policy). Results Out of 390 participants enrolled in Part 1, 190 entered Part 2. In Part 1, all four doses of amlitelimab demonstrated statistically significant improvements in percent change in EASI from baseline to Week-16 vs placebo; the highest response was seen with 250mg + LD group. Clinically meaningful improvements in key secondary endpoints were observed at Week-16, with continued improvements through Week-24. In Part 2, maintenance of EASI-75 and/or IGA 0/1 response at Week-52 was observed in 59%, 63%, 55%, and 66% of clinical responders withdrawn from 250mg + LD, 250mg, 125mg, and 62.5mg, respectively (NRI). Using treatment policy, 77%, 82%, 67%, and 74% maintained response off-drug, respectively. Those continuing amlitelimab treatment had numerically higher maintenance response rates. AD-related biomarkers were reduced during Part 1 and remained decreased over Part 2. Amlitelimab was well tolerated across all dose groups, with no new safety concerns identified during the 52-Weeks. Conclusion Clinically meaningful efficacy with amlitelimab was demonstrated over 52-Weeks, with an acceptable safety profile. Clinical responses were maintained in most patients 28-Weeks after treatment discontinuation. [ABSTRACT FROM AUTHOR]

Introduction Atopic dermatitis (AD) is a chronic inflammatory skin disease affecting 2–7% of adults globally, with 30% experiencing moderate-to-severe disease. Although several treatments for moderate-to-severe AD are available, the efficacy of many treatments has not been compared in head-to-head trials. Objectives Using a network meta-analysis (NMA), we evaluated the relative efficacy between lebrikizumab, an emerging biologic, and approved targeted systemic treatments for AD. Methods Double-blind, randomized, placebo-controlled clinical trials (systemic monotherapy-only) for moderate-to-severe AD in adults (≥18 years) and adolescents (≥12 years to ≤18 years) published before April 2023 were identified in a systematic literature review. Data were extracted for short-term (12–16 weeks) efficacy outcomes (Investigator's Global Assessment [IGA] 0/1 with ≥2-point improvement from baseline and the Eczema Area and Severity Index [EASI]) and patient-reported outcomes (Pruritus Numeric Rating Scale [NRS] with ≥4-point improvement from baseline). Bayesian NMAs were performed using random-effects models, with baseline-risk adjustment. Key estimates from the NMAs included pairwise differences between all treatments and absolute response rates for each treatment. Results Twenty-two clinical trials were included. For % achieving IGA 0/1, at 12–16 weeks, the estimated response rates (posterior median and 95% credible interval) for each of the treatments were: upadacitinib 30 mg 55.8% (43.7–64.2%), upadacitinib 15 mg 41.3% (30.1–50.0%), abrocitinib 200 mg 39.0% (29.8–47.8%), dupilumab 300 mg 31.8% (23.1–38.7%), lebrikizumab 250 mg 31.4% (24.1–39.2%), abrocitinib 100 mg 24.5% (17.5–32.0%), tralokinumab 300 mg 17.3% (12.8–22.2%), baricitinib 4 mg 16.7% (9.8–25.5%), baricitinib 2 mg 15.5% (9.6–22.0%), and placebo 6.0% (4.3–7.3%). Similar trends were observed for the EASI and pruritus NRS responses at 12–16 weeks. Conclusions This 16-week NMA shows that lebrikizumab had a similar response rate to dupilumab, the most widely used targeted systemic therapy for AD, and may represent a valuable treatment option for moderate-to-severe AD.

Introduction Atopic dermatitis (AD) is a common, chronic inflammatory disease requiring long-term, continuous therapy, yet in real life, patients may need to temporarily interrupt therapy. Objectives To indirectly compare long-term outcomes with lebrikizumab, tralokinumab, and dupilumab, we present an exploratory efficacy index, which accounts for on-drug and off-drug combined outcomes at Week 52. Methods The data set consisted of patients who, after 16 weeks, responded to treatment, defined as achieving either an IGA 0,1 or EASI 75 score, and who were randomized to receive maintenance dosages of lebrikizumab 250 mg Q4W (ADvocate1; ADvocate2), tralokinumab 300 mg Q2W (ECZTRA1; ECZTRA 2), and dupilumab 300 mg QW, Q2W (SOLO-CONTINUE) or were randomized to withdraw these treatments up to Week 52. The efficacy index is based on a weighted combination of response rates at Week 52, using non-responder imputation results, for IGA 0,1 or EASI 75, for patients who were either in the treatment continuation or the withdrawal arm. Here, we report the efficacy index, in which the weight places equal emphasis on continuing or stopping treatment, and we compare the efficacy index of tralokinumab and dupilumab with lebrikizumab. Results The efficacy index (95% CI) for lebrikizumab, tralokinumab, and dupilumab, respectively, was 53% (45%-61%), 45% (37%-53%), and 34% (28%-40%) with IGA 0,1; 63% (55%-71%), 42% (35%-49%), and 51% (45%-57%) with EASI 75. With IGA 0,1, lebrikizumab was statistically different from dupilumab; with EASI 75, lebrikizumab was statistically different from dupilumab and tralokinumab. Conclusions This novel efficacy index, which accounts for the importance of continuing or stopping therapy after Week 16, may be a useful tool to indirectly compare long-term treatment outcomes. Lebrikizumab's higher efficacy index may translate to improved long-term management of AD. [ABSTRACT FROM AUTHOR]

Atopic dermatitis is a chronic skin condition for which a range of systemic treatments have recently been approved. A treat-to-target strategy has been developed previously alongside an algorithm to guide the management of patients with atopic dermatitis. Here, we review the strategy and algorithm in the context of the evolving therapeutic landscape, and identify areas for further refinement and development. [ABSTRACT FROM AUTHOR]

Background/Objectives: Dupilumab‐associated ocular surface disease (DAOSD) is of particular relevance in patients with atopic dermatitis (AD). Guidance on DAOSD assessment and management in the Australian setting is needed to reduce its impact and minimise disruption to treatment. Methods: A systematic review of the literature was undertaken to identify data pertaining to the incidence, pathophysiology, risk factors and management of DAOSD. A critical review of this literature was used to inform a decision framework for dupilumab‐prescribers and develop a graded severity scoring tool to guide appropriate management options. Results: DAOSD typically emerges within 4 months of commencing dupilumab and the occurrence of new events diminishes over time. The reported incidence varies widely depending on the nature and source of the data: 8.6–22.1% (clinical trials programme), 0.5–70% (real‐world data; differences in study size, duration of follow‐up, ophthalmologist intervention, use of prophylaxis). Occurrence increases with AD severity and in patients with prior history of ocular disease; pathophysiology is still to be fully characterised. Management options have evolved over time and include lubricants/artificial tears, corticosteroids, calcineurin inhibitors, antihistamines, anti‐inflammatory agents and antimicrobial agents. Current therapies aim to resolve symptoms or reduce severity to levels sufficiently tolerable to enable continuation of dupilumab therapy. Conclusions: Recommendations for DAOSD assessment and management include identification of high‐risk patients, vigilance for red flags (keratoconus, herpetic and bacterial keratitis), regular assessment of symptom severity (before and during dupilumab therapy), conservative management of mild DAOSD by the prescribing physician and ophthalmologist referral for collaborative care of moderate–severe DAOSD and high‐risk patients.

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]

Ciclosporin (CsA) is a systemic immunosuppressive agent indicated for use in the treatment of patients with recalcitrant atopic dermatitis (AD). Studies demonstrate reasonable evidence of benefit compared with placebo. However as biologic agents are under development for use in AD, an assessment of the use, attitude to and safety of CsA is essential in understanding unmet needs in severe AD. We present the results of a survey asking questions relating to initial dose, duration of prescription, precautions and monitoring undertaken during treatment, adverse events seen, and hierarchy of use for systemic agents. This survey was distributed at the annual meeting of the Australasian College of Dermatologists. Twenty-two percent of respondents never prescribe CsA, and 50% prescribe it only 1–2 times per month. When prescribed, the most frequently recommended duration was 6–12 months (24%). Of prescribers, 56% start with a low dose of <3.5 mg/kg daily, and when stratified according to years of experience, a higher proportion of more junior dermatologists commenced with lower doses (p=.028). Regarding side effects, 95% of respondents expressed concern about nephrotoxicity, 37% about hypertension, and 17% infection. The results suggest that although most dermatologists consider CsA to be effective, there are concerns regarding the safety profile. [ABSTRACT FROM AUTHOR]

Background: Significant unmet need exists for long-term treatment of moderate to severe atopic dermatitis (AD).Objective: To assess the long-term safety and efficacy of dupilumab in patients with AD.Methods: This ongoing, multicenter, open-label extension study (NCT01949311) evaluated long-term dupilumab treatment in adults who had previously participated in phase 1 through 3 clinical trials of dupilumab for AD. This analysis examined patients given 300 mg dupilumab weekly for up to 76 weeks at data cutoff (April 2016). Safety was the primary outcome; efficacy was also evaluated.Results: Of 1491 enrolled patients (1042.9 patient-years), 92.9% were receiving treatment at cutoff. The safety profile was consistent with previously reported trials (420.4 adverse events/100 patient-years and 8.5 serious adverse events/100 patient-years), with no new safety signals; common adverse events included nasopharyngitis, conjunctivitis, and injection-site reactions. Sustained improvement was seen up to 76 weeks in all efficacy outcomes, including measures of skin inflammation, pruritus, and quality of life.Limitations: Lack of control arm, limited number of patients with 76 weeks or longer of treatment (median follow-up, 24 weeks), and patients not receiving the approved dose regimen of 300 mg every 2 weeks.Conclusion: The safety and efficacy profile from this study supports the role of dupilumab as continuous long-term treatment for patients with moderate to severe AD.

With the rapid development of new, targeted therapies for the treatment of moderate/severe atopic dermatitis, it is opportune to review the available conventional systemic agents. We assess the published evidence for systemic therapies for atopic dermatitis and amalgamate this with real‐world experience. Discussions are centred on when systemic therapy should be considered, which drug(s), what dose, how to sequence or combine these therapies, how long they should be continued for and what is considered success.

Background/Objectives: Atopic dermatitis (AD) has significant negative impact on health‐related quality of life, mood, sleep, work productivity and everyday activities. Research into the use of new drugs in the management of AD continues to develop, and international updates and recommendations have been published. However, questions remain in the Australian setting. This consensus aims to provide evidence‐based insights and practical advice on the management of adult AD in Australia. Methods: A panel (five dermatologists and one clinical immunologist) met to review the literature, critically examine clinical questions of relevance to Australian healthcare practitioners and develop a series of recommendation statements. A consensus panel, comprising the initial panel plus nine additional members, used a 2‐round Delphi voting process to determine a set of final guidance statements. Consensus: ≥75% agreement in the range 7–9. Results: Round 1 voting comprised 66 guidance statements. Of these, consensus was reached on 26, which were retained, and five were removed. The remainder (35) were modified and one new guidance statement was added for inclusion in round 2 voting. After round 2, consensus was reached on 35, which were retained, and one was removed (considered redundant). The 61 guidance statements upon which consensus was reached were then used to support a series of core consensus recommendations and a management flow chart. Conclusions: Expert consensus recommendations providing practical guidance of clinical relevance to specialists and primary care physicians in Australia have been developed. Dissemination of this guidance and evaluation of its impact on patient outcomes remain to be undertaken. [ABSTRACT FROM AUTHOR]

The aim of this article is to provide education to clinicians about certain barriers restricting the use of advanced targeted treatments in Australian health care. For illustrative purposes, the article focuses on dermatological conditions, but the content is relevant to all specialties that treat inflammatory and chronic diseases. Barriers to care discussed result in a lower than necessary standard of care for patients in Australia despite important advancements in medicine. [ABSTRACT FROM AUTHOR]

Sleep disturbance is considered one of the most prevalent symptoms of atopic dermatitis (AD), and is associated with daytime sleepiness, anxiety and depression. In previous phase 3 trials, dupilumab treatment demonstrated signif - icant improvement in objective AD signs and severity of symptoms, including sleep disturbance and mental health symptoms. To investigate the effect of dupilumab for up to 24 weeks on sleep quality, daytime sleepiness, anxiety and depression, using data from the DUPISTAD (NCT04033367) study. The randomized, phase 4 DUPISTAD study, was divided into two 12-week periods: an initial double-blind pla - cebo-controlled period, and a subsequent 12-week open-la - bel extension (OLE) period. The 24-week study enrolled adult patients with moderate-to-severe AD (Eczema Area and Severity Index score ≥12, Peak Pruritus Numeric Rating Scale [NRS] score ≥3, Sleep Disturbance NRS average score ≥5) who showed an inadequate response to topical treat - ments. These patients were randomized 2 :1 to dupilumab 300 mg every 2 weeks (q2w) for both the double-blind and OLE periods or placebo for the initial double-blind period, followed by dupilumab 300 mg q2w for the OLE period. The use of concomitant topical corticosteroids was permitted as needed by both groups throughout the study. Endpoints included mean change from baseline to week 24 for Patient-Reported Outcome Measures Information System (PROMIS) Sleep T-score (standardized score ranging from 30 [best] to 80 [worst], with a mean of 50), Epworth Sleepiness Scale (ESS; scored 0–24; higher values indicate increased daytime sleepiness), and Hospital Anxiety and Depression Scale (HADS; scored 0–21; higher values indicate a worse outcome). Throughout the study, patients also completed a Sleep Diary, recording the NRS of restfulness upon waking up (scored 0–10; lower values indicate a worse outcome). Statistical comparisons were not performed on the data collected during the OLE observation period. A total of 188 patients were enrolled in the study: 127 received continuous dupilumab (dupilumab–dupilumab group) and 61 received placebo to week 12 and then dupilumab to week 24 (placebo–dupilumab group). Baseline demographics and disease characteristics were well balanced. Improvement from baseline in sleep quality, daytime sleepiness, anxiety and depression was observed at week 24 in both groups, as illustrated by the mean change from baseline in PROMIS Sleep T-scores (−12.5 in the dupilumab–dupilumab group and −11.7 in the placebo–dupilumab group), ESS scores (−4.6 in the dupilumab–dupilumab group and −3.7 in the placebo–dupilumab group), HADS anxiety scores (−3.8 in the dupilumab– dupilumab group and −4.4 in the placebo–dupilumab group), HADS depression scores (−4.4 in the dupilumab–dupilumab group and −3.4 in the placebo–dupilumab group), and the NRS of restfulness upon a waking-up item of the Sleep Diary (+3.3 in the dupilumab–dupilumab group and +3.4 in the placebo–dupilumab group). The improvement achieved by the placebo–dupilumab group converged with that of the dupilumab–dupilumab group during the OLE period, as shown by the mean change from week 12 to week 24 in PROMIS Sleep T-score (−3.8), ESS score (−1.9), HADS anxiety score (−1.6), HADS depression score (−0.9) and NRS of restfulness upon a waking-up item of the Sleep Diary (+1.5). The safety profile of dupilumab was consistent with the known safety profile. Dupilumab provided sustained improvement through 24 weeks in patient-reported measures of sleep, daytime sleepiness, anxiety, and depression in adult patients with moderate-to-severe AD. Patients who were switched from placebo to dupilumab at week 12 showed rapid improvement in these parameters after the switch, eventually matching the improvement achieved by patients who received dupilumab from baseline through week 24.

Atopic dermatitis (AD) is a chronic disease characterized by sleep disturbance, associated with night-time itching and scratching, along with skin pain, resulting in daytime drowsiness, diminished daytime productivity and overall reduced quality of life (QoL) in patients with AD. To report the effect of up to 24 weeks of dupilumab treatment on the QoL of adult patients with moderate-to-severe AD, using data from the DUPISTAD (NCT04033367) study. Phase 4, a randomized DUPISTAD study, comprised two 12-week periods: an initial placebo-controlled double-blind period, and a subsequent 12-week open-label extension (OLE) period. Adult patients with moderate-to-severe AD (Eczema Area and Severity Index score ≥12, Peak Pruritus Numeric Rating Scale [NRS] score ≥3, Sleep Disturbance NRS average score ≥5), showing an inadequate response to topical treatments, were randomized 2:1 to dupilumab 300 mg every 2 weeks (q2w) for both the double-blind and OLE periods or placebo for the initial double-blind period, followed by dupilumab 300 mg q2w for the OLE period. The use of concomitant topical corticosteroids was permitted during the entire course of the study. Endpoints, including Patient-Oriented Eczema Measure (POEM; scored 0–28, with higher values indicating a worse outcome), Dermatology Life Quality Index (DLQI; scored 0–30, with higher values indicating a poorer QoL), Skin Pain and Sensitivity NRS (scored 0–10, where 0=no pain/normal sensitivity and 10=worst possible pain/ extremely sensitive) were assessed from baseline to week 24. The enrolled patients also completed a Work Productivity and Activity Impairment Questionnaire (WPAI-AD), including an NRS rating of the AD-Affected Ability to do Regular Daily Activities other than a Job (scored 0–10, where 0=‘no effect’ and 10=‘prevented me from doing my daily activities’). Formal statistical comparisons were not performed on the data resulting from the OLE period. The DUPISTAD study enrolled a total of 188 patients: 127 patients received dupilumab throughout (dupilumab–dupilumab group), and 61 patients received a placebo and then switched to dupilumab (placebo–dupilumab group). Baseline demographics and disease characteristics were well balanced. Improvement from baseline in AD-related patient-reported QoL indicators and AD symptoms was observed at week 24 in both groups, as illustrated by the mean change from baseline in POEM total scores (−14.6 in the dupilumab–dupilumab group and −15.9 in the placebo–dupilumab group), DLQI scores (−12.6 in the dupilumab–dupilumab group and −13.4 in the placebo–dupilumab group), Skin Pain NRS scores (−4.7 in the dupilumab–dupilumab group and −5.0 in the placebo–dupilumab group), Skin Sensitivity NRS scores (−4.6 in the dupilumab–dupilumab group and −5.0 in the placebo–dupilumab group), and the WPAI-AD NRS of Ability to do Regular Daily Activities scores (−4.2 in the dupilumab–dupilumab group and −3.8 in the placebo–dupilumab group). The placebo– dupilumab group experienced most of this improvement during the OLE period, as illustrated by the mean change from week 12 to week 24 in POEM total score (−11.5), DLQI score (−5.5), Skin Pain NRS score (−3.0), Skin Sensitivity NRS score (−3.0) and the WPAI-AD NRS of Ability to do Regular Daily Activities score (−2.0). The safety profile of dupilumab was consistent with the known safety profile. Dupilumab provided sustained improvements through 24 weeks in AD-related patient-reported measures of QoL and AD symptoms in adults with moderate-to-severe AD. Patients who were switched from placebo to dupilumab at week 12 showed rapid improvement in these parameters after the switch, eventually matching the improvement achieved by patients who received dupilumab from baseline through week 24.

SUMMARY The differences between topical corticosteroids are based mainly on their potency, safety and patient acceptability. The aim of this study was to evaluate a mild- to mid-potent topical corticosteroid, desonide 0.05%, on these three parameters in an Australian cohort of patients with facial seborrhoeic or atopic dermatitis. Eighty-one adult patients were randomized to receive desonide 0.05% lotion or its vehicle, applied twice daily for 3 weeks under double-blind conditions. In the active treatment group, 88% of patients had their skin condition cleared or almost cleared and only two patients experienced cutaneous adverse events (rash and pruritus). The acceptability of the lotion was high; 95% of patients stated they would use this topical corticosteroid again. These data support the short-term use of desonide 0.05% lotion as a suitable agent for the short-term treatment of facial dermatitis. [ABSTRACT FROM AUTHOR]

Objective: To determine the prevalence and severity of atopic dermatitis in a stratified cross-section of preschool-age children examined throughout Victoria, Australia. Design: A cross-sectional skin survey using a selected cluster sample of the various centers throughout Victoria. Setting: The study population included Victorian children attending child-care centers, preschools, and Maternal and Child Health Centres, with the reference population being Australian children aged 5 years and younger. Participants: Of 1634 potential participants, 1116 children (68.3%) were examined. Intervention: A dermatologist performed a total skin examination, including head and neck, limbs, and trunk, on all children. The diaper area was examined in children younger than 12 months. Main Outcome Measure: All parents were administered a questionnaire to elicit demographic information, history of skin conditions, and family history of skin problems or related diseases. The examiner recorded the presence, site, and severity of atopic dermatitis for calculation of age- and sex-specific prevalence rates. Results: The age- and sex-adjusted point prevalence was 30.8% (95% confidence interval [CI], 28.0%-33.5%). Most children (63.7%) were classified as having minimal or mild disease. Only 5.8% of children with atopic dermatitis did not have face or flexural involvement. Of the 237 children with atopic dermatitis and information available, 209 used 1 or more products to treat their condition. Conclusions: Atopic dermatitis is common, decreasing in prevalence after the first 3 years of life. Most children have mild disease requiring little if any treatment, and much could be prevented with simple measures. Educational programs directed at those caring for preschoolage children that provide information on simple preventive measures, where practical, and sources of advice for treatment, if necessary, could substantially reduce the morbidity of this condition in predisposed children.

Background: Dupilumab (an anti-interleukin-4-receptor-α monoclonal antibody) blocks signalling of interleukin 4 and interleukin 13, type 2/Th2 cytokines implicated in numerous allergic diseases ranging from asthma to atopic dermatitis. Previous 16-week monotherapy studies showed that dupilumab substantially improved signs and symptoms of moderate-to-severe atopic dermatitis with acceptable safety, validating the crucial role of interleukin 4 and interleukin 13 in atopic dermatitis pathogenesis. We aimed to evaluate the long-term efficacy and safety of dupilumab with medium-potency topical corticosteroids versus placebo with topical corticosteroids in adults with moderate-to-severe atopic dermatitis.Methods: In this 1-year, randomised, double-blinded, placebo-controlled, phase 3 study (LIBERTY AD CHRONOS), adults with moderate-to-severe atopic dermatitis and inadequate response to topical corticosteroids were enrolled at 161 hospitals, clinics, and academic institutions in 14 countries in Europe, Asia-Pacific, and North America. Patients were randomly assigned (3:1:3) to subcutaneous dupilumab 300 mg once weekly (qw), dupilumab 300 mg every 2 weeks (q2w), or placebo via a central interactive voice/web response system, stratified by severity and global region. All three groups were given concomitant topical corticosteroids with or without topical calcineurin inhibitors where inadvisable for topical corticosteroids. Topical corticosteroids could be tapered, stopped, or restarted on the basis of disease activity. Coprimary endpoints were patients (%) achieving Investigator's Global Assessment (IGA) 0/1 and 2-point or higher improvement from baseline, and Eczema Area and Severity Index 75% improvement from baseline (EASI-75) at week 16. Week 16 efficacy and week 52 safety analyses included all randomised patients; week 52 efficacy included patients who completed treatment by US regulatory submission cutoff. This study is registered with ClinicalTrials.gov, NCT02260986.Findings: Between Oct 3, 2014, and July 31, 2015, 740 patients were enrolled: 319 were randomly assigned to dupilumab qw plus topical corticosteroids, 106 to dupilumab q2w plus topical corticosteroids, and 315 to placebo plus topical corticosteroids. 623 (270, 89, and 264, respectively) were evaluable for week 52 efficacy. At week 16, more patients who received dupilumab plus topical corticosteroids achieved the coprimary endpoints of IGA 0/1 (39% [125 patients] who received dupilumab plus topical corticosteroids qw and 39% [41 patients] who received dupilumab q2w plus topical corticosteroids vs 12% [39 patients] who received placebo plus topical corticosteroids; p<0·0001) and EASI-75 (64% [204] and 69% [73] vs 23% [73]; p<0·0001). Week 52 results were similar. Adverse events were reported in 261 (83%) patients who received dupilumab qw plus topical corticosteroids, 97 (88%) patients who received dupilumab q2w, and 266 (84%) patients who received placebo, and serious adverse events in nine (3%), four (4%), and 16 (5%) patients, respectively. No significant dupilumab-induced laboratory abnormalities were noted. Injection-site reactions and conjunctivitis were more common in patients treated with dupilumab plus topical corticosteroids-treated patients than in patients treated with placebo plus topical corticosteroids.Interpretation: Dupilumab added to standard topical corticosteroid treatment for 1 year improved atopic dermatitis signs and symptoms, with acceptable safety.Funding: Sanofi and Regeneron Pharmaceuticals Inc.
