Project description:ImportanceAdolescents with atopic dermatitis (AD) have high disease burden negatively affecting quality of life, with limited treatment options. The efficacy and safety of dupilumab, a monoclonal antibody, approved for treatment in adolescent patients with inadequately controlled AD, remain unknown in this patient population.ObjectiveTo assess the efficacy and safety of dupilumab monotherapy in adolescents with moderate to severe inadequately controlled AD.Design, setting, and participantsA randomized, double-blind, parallel-group, phase 3 clinical trial was conducted at 45 US and Canadian centers between March 21, 2017, and June 5, 2018. A total of 251 adolescents with moderate to severe AD inadequately controlled by topical medications or for whom topical therapy was inadvisable were included.InterventionsPatients were randomized (1:1:1; interactive-response system; stratified by severity and body weight) to 16-week treatment with dupilumab, 200 mg (n = 43; baseline weight <60 kg), or dupilumab, 300 mg (n = 39; baseline weight ≥60 kg), every 2 weeks; dupilumab, 300 mg, every 4 weeks (n = 84); or placebo (n = 85).Main outcomes and measuresProportion of patients with 75% or more improvement from baseline in Eczema Area and Severity Index (EASI-75) (scores range from 0 to 72, with higher scores indicating greater severity) and Investigator's Global Assessment (IGA) 0 or 1 on a 5-point scale (scores range from 0 to 4, with higher scores indicating greater severity) at week 16.ResultsA total of 251 patients were randomized (mean [SD] age, 14.5 [1.7] years; 148 [59.0%] male). Of 250 patients with data available on concurrent allergic conditions, most had comorbid type 2 diseases (asthma, 134 [53.6%]; food allergies, 60.8%; allergic rhinitis, 65.6%). A total of 240 patients (95.6%) completed the study. Dupilumab achieved both coprimary end points at week 16. The proportion of patients with EASI-75 improvement from baseline increased (every 2 weeks, 41.5%; every 4 weeks, 38.1%; placebo, 8.2%) with differences vs placebo of 33.2% (95% CI, 21.1%-45.4%) for every 2 weeks and 29.9% (95% CI, 17.9%-41.8%) for every 4 weeks (P < .001). Efficacy of the every-2-week regimen was generally superior to the every-4-week regimen. Patients in the dupilumab arms had higher percentage values of conjunctivitis (every 2 weeks, 9.8%; every 4 weeks, 10.8%; placebo, 4.7%) and injection-site reactions (every 2 weeks, 8.5%; every 4 weeks, 6.0%; placebo, 3.5%), and lower nonherpetic skin infections (every 2 weeks, 9.8%; every 4 weeks, 9.6%; placebo, 18.8%).Conclusions and relevanceIn this study, dupilumab significantly improved AD signs, symptoms, and quality of life in adolescents with moderate to severe AD, with an acceptable safety profile. Placebo-corrected efficacy and safety of dupilumab were similar in adolescents and adults.Trial registrationClinicalTrials.gov identifier: NCT03054428.

Project description:ImportanceAtopic dermatitis (AD) is a chronic, recurrent, inflammatory skin disease with an unmet need for treatments that provide rapid and high levels of skin clearance and itch improvement.ObjectiveTo assess the safety and efficacy of upadacitinib vs dupilumab in adults with moderate-to-severe AD.Design, setting, and participantsHeads Up was a 24-week, head-to-head, phase 3b, multicenter, randomized, double-blinded, double-dummy, active-controlled clinical trial comparing the safety and efficacy of upadacitinib with dupilumab among 692 adults with moderate-to-severe AD who were candidates for systemic therapy. The study was conducted from February 21, 2019, to December 9, 2020, at 129 centers located in 22 countries across Europe, North and South America, Oceania, and the Asia-Pacific region. Efficacy analyses were conducted in the intent-to-treat population.InterventionsPatients were randomized 1:1 and treated with oral upadacitinib, 30 mg once daily, or subcutaneous dupilumab, 300 mg every other week.Main outcomes and measuresThe primary end point was achievement of 75% improvement in the Eczema Area and Severity Index (EASI75) at week 16. Secondary end points were percentage change from baseline in the Worst Pruritus Numerical Rating Scale (NRS) (weekly average), proportion of patients achieving EASI100 and EASI90 at week 16, percentage change from baseline in Worst Pruritus NRS at week 4, proportion of patients achieving EASI75 at week 2, percentage change from baseline in Worst Pruritus NRS (weekly average) at week 1, and Worst Pruritus NRS (weekly average) improvement of 4 points or more at week 16. End points at week 24 included EASI75, EASI90, EASI100, and improvement of 4 points or more in Worst Pruritus NRS from baseline (weekly average). Safety was assessed as treatment-emergent adverse events in all patients receiving 1 or more dose of either drug.ResultsOf 924 patients screened, 348 (183 men [52.6%]; mean [SD] age, 36.6 [14.6] years) were randomized to receive upadacitinib and 344 were randomized to receive dupilumab (194 men [56.4%]; mean [SD] age, 36.9 [14.1] years); demographic and disease characteristics were balanced among treatment groups. At week 16, 247 patients receiving upadacitinib (71.0%) and 210 patients receiving dupilumab (61.1%) achieved EASI75 (P = .006). All ranked secondary end points also demonstrated the superiority of upadacitinib vs dupilumab, including improvement in Worst Pruritus NRS as early as week 1 (mean [SE], 31.4% [1.7%] vs 8.8% [1.8%]; P < .001), achievement of EASI75 as early as week 2 (152 [43.7%] vs 60 [17.4%]; P < .001), and achievement of EASI100 at week 16 (97 [27.9%] vs 26 [7.6%]; P < .001). Rates of serious infection, eczema herpeticum, herpes zoster, and laboratory-related adverse events were higher for patients who received upadacitinib, whereas rates of conjunctivitis and injection-site reactions were higher for patients who received dupilumab.Conclusions and relevanceDuring 16 weeks of treatment, upadacitinib demonstrated superior efficacy vs dupilumab in patients with moderate-to-severe AD, with no new safety signals.Trial registrationClinicalTrials.gov Identifier: NCT03738397.

Project description:BackgroundDupilumab, a human monoclonal antibody, blocks the shared receptor unit for interleukin-4 and interleukin-13. International phase II and III studies have evaluated the efficacy and safety of dupilumab in adults with moderate-to-severe atopic dermatitis (AD), but the effects of dupilumab in Japanese patients have not been reported.ObjectivesTo evaluate the efficacy and safety of dupilumab in Japanese patients with moderate-to-severe AD.MethodsWe analysed the efficacy and safety of dupilumab in the Japanese cohorts of a 16-week, phase IIb dose-finding trial (AD-1021; NCT01859988); a 16-week, phase III, placebo-controlled monotherapy trial (LIBERTY AD SOLO 1; NCT02277743) and a 52-week, phase III, placebo-controlled study of dupilumab with topical corticosteroids (LIBERTY AD CHRONOS; NCT02260986).ResultsTwenty-seven, 106 and 117 Japanese patients were enrolled in AD-1021, SOLO 1 and CHRONOS, respectively. Baseline disease severity was numerically higher in the Japanese cohort than in the overall study population. Generally, dupilumab significantly improved signs and symptoms of AD, including pruritus and patient quality of life, compared with placebo in the Japanese cohort, consistent with the overall study population. The combined safety profile of dupilumab in the Japanese cohort was similar to that in the total study populations; dupilumab was associated with an increased incidence of injection-site reactions and conjunctivitis compared with placebo. Dupilumab was associated with rapid reduction in thymus and activation-regulated chemokine and gradual IgE reductions.ConclusionsDupilumab alone or with topical corticosteroids improved signs and symptoms of AD, had an acceptable safety profile, and suppressed biomarkers of type 2 inflammation compared with placebo in Japanese adult patients with moderate-to-severe AD. What's already known about this topic? Differences in atopic dermatitis (AD) pathology have been reported between Asian and Western populations, in which distinct helper T-cell activation profiles have been observed. International clinical studies in adults with moderate-to-severe AD have evaluated the efficacy and safety of dupilumab, which blocks interleukin-4 and interleukin-13, key molecules in type 2 inflammation. The effects of dupilumab in Japanese patients specifically have not yet been reported. What does this study add? Dupilumab alone or with topical corticosteroids improved signs and symptoms of AD and had an acceptable safety profile compared with placebo in Japanese patients with moderate-to-severe AD. The effects were comparable with those observed in the overall study population. Reported immunological differences in AD pathology in Asian patients may be secondary to type 2 immune activation.

Project description:BackgroundModerate-to-severe atopic dermatitis (AD) in the adolescence is a high burden disease, and its treatment can be very challenging due to paucity of approved systemic drugs for this age and their side-effects. Dupilumab was recently approved for treatment of adolescent AD.ObjectivesA multicentre, prospective, real-world study on the effectiveness and safety of dupilumab in adolescents (aged from ≥12 to <18 years) with moderate-to-severe AD was conducted. The main AD clinical phenotypes were also examined.MethodsData of adolescents with moderate-to-severe AD treated with dupilumab at label dosage for 16 weeks were collected. Treatment outcome was assessed by EASI, NRS itch, NRS sleep loss and CDLQI scores at baseline and after 16 weeks of treatment. The clinical scores were also evaluated according to clinical phenotypes.ResultsOne hundred and thirty-nine adolescents were enrolled in the study. Flexural eczema and head and neck eczema were the most frequent clinical phenotypes, followed by hand eczema and portrait-like dermatitis. Coexistence of more than 1 phenotype was documented in 126/139 (88.5%) adolescents. Three patients (2.1%) contracted asymptomatic SARS-CoV-2 infection and 1 of the discontinued dupilumab treatment before the target treatment period. A significant improvement in EASI, NRS itch, NRS sleep loss and CDLQI was observed after 16 weeks of treatment with dupilumab. This outcome was better than that observed in clinical trials. Dupilumab resulted effective in all AD phenotypes, especially in diffuse eczema. Twenty-eight (20.1%) patients reported adverse events, conjunctivitis and flushing being the most frequent. None of patients discontinued dupilumab due to adverse event.ConclusionsDupilumab in adolescent AD showed excellent effectiveness at week 16 with consistent improvement of all clinical scores. Moreover, dupilumab showed a good safety profile also in this COVID-19 pandemic era.

Project description:We report 10 cases of conjunctivitis in atopic dermatitis (AD) patients treated with dupilumab from November 2017 to November 2018 in our institution, who were referred to the ophthalmology department for diagnosis and management of conjunctivitis. We also describe ocular surface findings in these patients before the first injection of dupilumab. During the first 6 months post initiation of dupilumab, incidence of conjunctivitis was 27% (5/18) in patients treated from November 2017 to April 2018 who had not had ocular examination previously. This rate dropped to 12% (3/25) after systematic ophthalmological referral before initiation of dupilumab. Patients who developed conjunctivitis had mean SCORAD score (Scoring Atopic Dermatitis) of 60.4 ± 20 (35-88) and mean EASI score (Eczema Area and Severity Index) of 37 ± 17 (14.6-56). Mean age was 36 years (20-51). Most patients had a long history of AD (> 10 years). Mean delay of ocular surface inflammation was 3.5 months, ranging from 1 to 8 months. One patient had to discontinue dupilumab because of severe follicular conjunctivitis. We observed two clinical patterns of ocular surface diseases: a mild non-specific conjunctivitis with dry eyes, which improved with warm compresses and artificial tears without any recurrence; and a severe dupilumab-induced follicular conjunctivitis without keratitis, which required specific ophthalmological management.

Project description:IntroductionPatients with atopic dermatitis (AD) have high disease burden negatively affecting quality of life.AimTo assess the efficacy and safety of dupilumab in patients with moderate-to-severe AD.Material and methodsA systematic literature search was performed using the main-stream databases of PubMed, Web of Science, and Embase. Standard mean difference (SMD) or risk ratios (RR) with 95% confidence interval (95% CI) were calculated using a fixed-effects or random-effects model.ResultsA total of 11 studies with 4094 patients met the inclusion criteria and were included in this meta-analysis. Pooled estimate showed that dupilumab significantly improved the mean change in the Eczema Area and Severity Index (EASI) score (SMD = -10.90, 95% CI: -12.13, -9.68; p < 0.001), percentage of body surface area (BSA) affected (SMD = -10.87, 95% CI: -13.04, -8.70; p < 0.001), pruritus numeric rating scale (NRS) scores (SMD = -9.29, 95% CI: -10.34, -8.25; p < 0.001), and Dermatology Life Quality Index (DLQI) scores (SMD = -9.66, 95% CI: -11.50, -7.82; p < 0.001). In addition, dupilumab was associated with a significantly higher Investigator's Global Assessment (IGA) response (RR = 3.57, 95% CI: 2.53, 5.03; p < 0.001). The overall incidence of adverse events was comparable between dupilumab and other treatments (RR = 1.00, 95% CI: 0.96, 1.03; p = 0.832). However, the injection-site reaction, headache and conjunctivitis were more frequently seen in patients treated with dupilumab.ConclusionsDupilumab is well tolerated, and could improve signs and symptoms of AD. However, the results should be interpreted cautiously since there was significant heterogeneity among the studies.

Project description:IntroductionTreatment options for children younger than 6 years with severe atopic dermatitis (AD) are limited, as systemic immunosuppressants may present safety concerns in this young age group. Dupilumab is the first systemic treatment option approved for infants and young children with severe AD in the European Union. This study reports the efficacy and safety of dupilumab with concomitant low-potency corticosteroids in children aged 6 months to 5 years with severe AD.MethodsThis was a pre-specified subgroup analysis of data for patients aged 6 months to 5 years with severe AD at baseline (Investigator's Global Assessment [IGA] = 4) from a randomised, double-blind, placebo-controlled, phase III trial of dupilumab. Patients were randomised to either subcutaneously administered dupilumab (200/300 mg) or matched placebo every 4 weeks, plus low-potency topical corticosteroids for 16 weeks. Co-primary endpoints at week 16 were the proportion of patients with IGA ≤ 1 (clear or almost clear skin) and the proportion of patients with ≥ 75% improvement from baseline in Eczema Area and Severity Index (EASI-75). Secondary endpoints at week 16 included mean changes in EASI, pruritus, skin pain, sleep loss and quality of life.ResultsThe analysis included 125 patients (63 receiving dupilumab vs. 62 placebo). At week 16, significantly more patients receiving dupilumab vs. placebo had achieved IGA ≤ 1 (14.3% vs. 1.6%; P = 0.0085) and EASI-75 (46.0% vs. 6.6%; P < 0.0001). Significant improvements with dupilumab were observed in all secondary endpoints, including a least squares mean 48.9% reduction in pruritus. The overall incidence of adverse events (AEs) was similar between the dupilumab and placebo groups (66.7% vs. 73.8%). No dupilumab-related AEs were serious or led to treatment discontinuation.ConclusionDupilumab significantly improved AD signs, symptoms and quality of life in children aged 6 months to 5 years with severe AD with acceptable safety.Trial registrationThe trial was registered with ClinicalTrials.gov with ID number NCT03346434, part B.

Project description:BackgroundDupilumab is an antibody against interleukin-4 receptor α, used in the treatment of atopic dermatitis (AD).ObjectivesTo evaluate the efficacy and safety of dupilumab in adult Chinese patients with moderate-to-severe AD.MethodsIn this randomized, double-blind, placebo-controlled, parallel-group, phase III study, conducted between December 2018 and February 2020, patients with AD received dupilumab (300 mg) or placebo once every 2 weeks for 16 weeks, and were followed up for 12 weeks. The primary efficacy endpoint was the proportion of patients with both an Investigator's Global Assessment score of 0-1 and a reduction from baseline of ≥ 2 points at week 16.ResultsOverall, 165 patients (mean age 30·6 years; 71·5% male patients) were randomized; 82 patients were randomized to dupilumab and 83 patients were randomized to placebo. At week 16, 26·8% of patients in the dupilumab group and 4·8% of patients in the placebo group achieved the primary endpoint [difference 22·0%, 95% confidence interval (CI) 11·37-32·65; P < 0·001]. Compared with placebo, higher proportions of patients in the dupilumab group achieved ≥ 75% reduction in the Eczema Area and Severity Index score (57·3% vs. 14·5%; difference 42·9%, 95% CI 29·75-55·97; P < 0·001) and had ≥ 3-point (52·4% vs. 9·6%; difference 42·8%, 95% CI 30·26-55·34; P < 0·001) and ≥ 4-point (39·0% vs. 4·8%; difference 34·2%, 95% CI 22·69-45·72; P < 0·001) reductions in weekly average daily peak daily pruritus numerical rating scale scores. The incidence of treatment-emergent adverse events during the treatment period was similar in the two groups. The incidence of conjunctivitis, allergic conjunctivitis and injection site reaction was higher in the dupilumab group than in the placebo group.ConclusionsIn adult Chinese patients, dupilumab was effective in improving the signs and symptoms of AD and demonstrated a favourable safety profile.
