Project description:Atopic dermatitis (AD) is a chronic, relapsing, inflammatory skin disease characterized by itch and clinical heterogeneity regarding the age of onset, morphology, distribution, and severity of lesions. Severe AD has a significant impact on the quality of life of affected children and their caregivers. Children with moderate-severe AD inadequately controlled with topical therapy have limited treatment options, such as systemic corticosteroids or phototherapy, often prescribed as off-label treatments, often with unfavorable benefit-to-risk ratio adverse events. Dupilumab is a fully human monoclonal antibody with proven effectiveness and a relatively safe adverse effect profile in patients with type 2 inflammatory diseases, including AD. We report three pediatric cases of severe AD successfully treated with dupilumab.

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

Project description:BackgroundTwo phase III trials, ECZTRA 1 and 2, confirmed the efficacy and safety of tralokinumab versus placebo in adults with moderate-to-severe atopic dermatitis (AD). To further explore the long-term efficacy of tralokinumab for AD, a pooled analysis of these trials was conducted.MethodsECZTRA 1 and 2 patients (n = 1596 total) were randomized to tralokinumab 300 mg or placebo every 2 weeks (q2w) over 16 weeks. Patients achieving Investigator's Global Assessment of clear/almost clear skin (IGA 0/1) and/or 75% improvement in the Eczema Area and Severity Index (EASI-75) at Week 16, were re-randomized to tralokinumab q2w, every 4 weeks (q4w), or placebo (tralokinumab withdrawal) for another 36 weeks. Patients not achieving the response criteria at Week 16 received open-label tralokinumab q2w plus optional topical corticosteroids (TCS). A pooled, prespecified analysis assessed the proportions of Week 16 responders that maintained IGA 0/1 and/or EASI-75 at Week 52. Pooled data from all patients initiated with tralokinumab, regardless of the response at Week 16 or dosing regimen received thereafter, were analyzed post hoc.ResultsIn patients who achieved the primary endpoints at Week 16, IGA 0/1 responses were maintained at Week 52 without rescue treatment (including TCS) by 55.9%, 42.4%, and 34.0% of patients re-randomized to tralokinumab q2w, q4w, or placebo (tralokinumab withdrawal), respectively, while EASI-75 responses were maintained by 57.3%, 50.4%, and 26.4%, respectively (prespecified analysis). In a post hoc analysis of all patients initiated with tralokinumab, response rates improved over time with continued tralokinumab treatment beyond Week 16 to Week 52 for EASI-50 (63.1-82.7%), EASI-75 (37.6-61.8%), EASI-90 (20.4-37.3%), and IGA 0/1 (23.0-36.2%).ConclusionsTralokinumab treatment provides progressive and sustained improvement over 1 year in the extent and severity of AD in patients with moderate-to-severe AD.Clinical trial registrationNCT03131648 (ECZTRA 1); study start date: 30 May 2017; primary completion date: 7 August 2018; study completion date: 10 October 2019.

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:BackgroundThe patho-mechanism of ocular surface disease (OSD) in dupilumab-treated atopic dermatitis (AD) patients remains unclear. The aim of this study is to measure dupilumab levels in tear fluid and serum, and relate these findings to the severity of OSD during dupilumab treatment in AD patients.MethodsThis prospective study included dupilumab-treated moderate-to-severe AD patients who were seen by a dermatologist and an ophthalmologist before the start of dupilumab (baseline), and after 4 and 28 weeks of dupilumab treatment. Dupilumab levels in tear fluid and serum were measured by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). Additionally, a pilot study was conducted to measure dupilumab on conjunctival epithelial cells using flow cytometry and LC-MS/MS.ResultsAt baseline, 89.6% (n = 43/48) of the patients had OSD, with 50.0% having moderate-to-severe OSD. After 28 weeks of dupilumab treatment, the median dupilumab tear fluid levels were 0.55 mg/L (IQR 0.35-1.31) and 0.29 mg/L (IQR 0.16-0.60) in patients with moderate-to-severe OSD and patients with no or mild OSD, respectively (p = 0.02). Dupilumab levels could be detected on conjunctival epithelial cells of 5 AD patients treated with dupilumab for 4 weeks.ConclusionPatients with moderate-to-severe OSD had higher dupilumab tear fluid levels compared to patients with no or mild OSD, indicating that dupilumab reaches the ocular surface. Dupilumab was also detected in conjunctival cell suspensions and was found to directly bind CD45-conjunctival epithelial cells. This suggests that AD-induced changes of the conjunctival epithelium may play a role in the development of OSD as well as increased local drug availability.

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.
