Abstract
BACKGROUND Pediatric patients with moderate-to-severe atopic dermatitis (AD) often experience a high disease burden and have a high risk of persistent disease. Standard-of-care immunosuppressive systemic treatments have been used off-label for AD in pediatric patients despite concerns for suboptimal safety with continuous use and risk of relapse upon discontinuation. The biologic agent dupilumab is the first systemic treatment approved for moderate-to-severe AD in children as young as 6 months. Long-term safety and efficacy data in this patient population are needed to inform continuous AD management. OBJECTIVES The purpose of this work was to determine the long-term safety and efficacy of dupilumab treatment up to 1 year in an open-label extension (OLE) study [LIBERTY AD PED-OLE (NCT02612454)] in children aged 6 months to 5 years with moderate-to-severe AD who previously participated in the 16-week, double-blind, phase 3 LIBERTY AD PRESCHOOL trial (NCT03346434 part B; parent study) and were subsequently enrolled in PED-OLE. METHODS In PED-OLE, patients received dupilumab every 4 weeks according to a weight-tiered regimen (body weight ≥ 5 kg to < 15 kg: 200 mg; ≥ 15 kg to < 30 kg: 300 mg). RESULTS Data for 142 patients were analyzed, 60 of whom had completed the 52-week visit at time of database lock. Mean age at baseline was 4.1 y [SD, 1.13; range, 1.0-5.9 years]. A majority (78.2%) of patients reported ≥ 1 treatment-emergent adverse event (TEAE), most of which were mild or moderate and transient. The most frequently reported TEAEs were nasopharyngitis (19.7%), cough (15.5%), and pyrexia (14.1%). One TEAE led to treatment discontinuation (severe urticaria, which resolved in 1 day). By week 52, 36.2% of patients had achieved an Investigator's Global Assessment score of 0/1 (clear/almost clear skin), and 96.6%, 79.3%, and 58.6% had at least 50%, 75%, or 90% improvement, respectively, in Eczema Area and Severity Index scores. CONCLUSIONS Consistent with results seen in adults, adolescents, and older children (aged 6-11 years), treatment with dupilumab for up to 1 year in children aged 6 months to 5 years with inadequately controlled moderate-to-severe AD demonstrated an acceptable long-term safety profile and sustained efficacy. These results support the long-term continuous use of dupilumab in this patient population. TRIAL REGISTRATION ClinicalTrials.gov Identifiers: NCT02612454 and NCT03346434 (part B).

Abstract
BACKGROUND Atopic dermatitis (AD), a highly pruritic, inflammatory skin disease, affects approximately 7% of adolescents globally. A topical formulation of ruxolitinib, a Janus kinase (JAK) 1/JAK2 inhibitor, demonstrated safety and efficacy among adolescents/adults in two phase 3 studies (TRuE-AD1/TRuE-AD2). OBJECTIVE To describe safety and efficacy of 1.5% ruxolitinib cream versus vehicle and long-term disease control of ruxolitinib cream among adolescents aged 12-17 years from pooled phase 3 study data. METHODS Patients [≥ 12 years old with AD for ≥ 2 years, Investigator's Global Assessment score (IGA) 2/3, and 3-20% affected body surface area (BSA) at baseline] were randomized 2:2:1 to ruxolitinib cream (0.75%/1.5%) or vehicle for 8 weeks of continuous use followed by a long-term safety (LTS) period up to 52 weeks with as-needed use. Patients originally applying vehicle were rerandomized 1:1 to 0.75%/1.5% ruxolitinib cream. Efficacy measures at week 8 included IGA treatment success (IGA-TS; i.e., score of 0/1 with ≥ 2 grade improvement from baseline), ≥ 75% improvement in Eczema Area and Severity Index (EASI-75), and ≥ 4-point improvement in itch numerical rating scale (NRS4). Measures of disease control during the LTS period included IGA score of 0 (clear) or 1 (almost clear) and percentage affected BSA. Safety was assessed throughout the study. RESULTS Of 1249 randomized patients, 245 (19.6%) were aged 12-17 years. Of these, 45 patients were randomized to vehicle and 92 patients to 1.5% ruxolitinib cream. A total of 104/137 (75.9%) patients continued on 1.5% ruxolitinib cream in the LTS period [82/92 (89.1%) continued on 1.5% ruxolitinib cream; 22/45 (48.9%) patients on vehicle were reassigned to 1.5% ruxolitinib cream], and 83/104 (79.8%) of these patients completed the LTS period. At week 8, substantially more patients who applied 1.5% ruxolitinib cream versus vehicle achieved IGA-TS (50.6% versus 14.0%), EASI-75 (60.9% versus 34.9%), and NRS4 (52.1% versus 17.4%; P = 0.009). The mean (SD) reduction in itch NRS scores was significantly greater in patients applying 1.5% ruxolitinib cream versus vehicle from day 2 [- 0.9 (1.9) versus -0.2 (1.4); P = 0.03]. During the LTS period, mean (SD) trough steady-state ruxolitinib plasma concentrations at weeks 12/52 were 27.2 (55.7)/15.5 (31.5) nM. The percentage of patients achieving IGA score of 0 or 1 was sustained or further increased with 1.5% ruxolitinib cream; mean affected BSA was generally low (< 3%; i.e., mild disease). Through 52 weeks, application site reactions occurred in 1.8% of adolescent patients applying 1.5% ruxolitinib cream at any time; no patients had serious adverse events. There were no serious infections, malignancies, major adverse cardiovascular events, or thromboembolic events. CONCLUSIONS Meaningful anti-inflammatory and antipruritic effects were demonstrated with 1.5% ruxolitinib cream in the subset of adolescent patients with AD, comparable with those observed in the overall study population; long-term, as-needed use maintained disease control and was well tolerated.

Abstract
BACKGROUND AND OBJECTIVE Current regulatory labeling recommends avoiding live vaccine use in dupilumab-treated patients. Clinical data are not available to support more specific guidance for live or live attenuated vaccines administration in dupilumab-treated patients. METHODS Children (6 months-5 years old) with moderate-to-severe atopic dermatitis (AD) enrolled in a phase 2/3 clinical trial of dupilumab (LIBERTY AD PRESCHOOL Part A/B; NCT03346434) and subsequently participated in the LIBERTY AD PED-OLE (NCT02612454). During these studies, protocol deviations occurred in nine children who received measles, mumps, rubella (MMR) vaccine with or without varicella vaccine; five with a ≤12-week gap between dupilumab administration and vaccination and four with a >12-week gap after discontinuing dupilumab. RESULTS Nine children (1 female; 8 male) had severe AD at baseline (8-56 months old). Of the nine children, five had a ≤12-week gap ranged 1-7 weeks between dupilumab administration and vaccination who received MMR vaccine (n = 2) or MMR and varicella vaccines (n = 3); among these, one resumed dupilumab treatment as early as 2 days and four resumed treatment 18-43 days after vaccination. No treatment-emergent adverse events, including serious adverse events and infections, were reported within the 4-week post-vaccination period in any children. CONCLUSIONS In this case series of dupilumab-treated children with severe AD who received MMR vaccine with or without varicella vaccine, no adverse effects (including vaccine-related infection) were reported within 4 weeks after vaccination. Further studies are warranted to evaluate the safety, tolerability, and immune response to live attenuated vaccines in dupilumab-treated patients.

Abstract
BACKGROUND Patients with atopic dermatitis (AD), particularly infants and young children, are at greater risk of developing skin infections. In this study, we assessed infection rates in AD patients aged 6 months to 5 years treated with dupilumab. METHODS In LIBERTY AD PRESCHOOL, a double-blind, placebo-controlled, phase III clinical trial, children aged 6 months to 5 years with moderate-to-severe AD were randomized 1:1 to subcutaneous dupilumab or placebo, with concomitant low-potency topical corticosteroids, every 4 weeks for 16 weeks. Exposure-adjusted infection rates were used to compare treatment groups. RESULTS The analysis included 162 patients, of whom 83 received dupilumab and 79 received placebo. Total infection rates were not significantly different between the dupilumab and placebo groups (rate ratio [RR] 0.75, 95% CI 0.48-1.19; p = 0.223). Non-herpetic adjudicated skin infections and bacterial infections were significantly less frequent with dupilumab versus placebo (non-herpetic skin infections: RR 0.46, 95% CI 0.21-0.99; p = 0.047; bacterial infections: RR 0.09, 95% CI 0.01-0.67; p = 0.019), and the number of patients using systemic anti-infective medication was significantly lower in the dupilumab group (RR 0.52, 95% CI 0.30-0.89; p = 0.019). There were no significant differences in the number of herpetic infections between the dupilumab and placebo groups (RR 1.17, 95% CI 0.31-4.35; p = 0.817). The number of patients with two or more infection events was significantly higher in the placebo group (RR 0.29, 95% CI 0.12-0.68; p = 0.004), and no severe or serious infections (including eczema herpeticum) were observed among patients receiving dupilumab. CONCLUSIONS These data suggest that dupilumab treatment in infants and children younger than 6 years with AD does not increase overall risk of infections and is associated with a reduced risk of bacterial and non-herpetic skin infections compared with placebo, resulting in a reduced need for anti-infective medication. TRIAL REGISTRATION The trial was registered with ClinicalTrials.gov with ID number NCT03346434 on November 17, 2017. INFOGRAPHIC.

Abstract
BACKGROUND While the majority of patients with atopic dermatitis (AD) achieve disease control with dupilumab treatment, there is variability in which patients achieve clear disease. The predictors of these responses are currently unclear. Integrated models were developed to evaluate the exposure-response (E-R) relationship of dupilumab in children, adolescents, and adults with AD. METHODS Data from six Phase II and III clinical studies were pooled (2,366 adults [> 18 years], 243 adolescents [≥ 12 to < 18 years] and 359 children [≥ 6 to < 12 years]) for model development. Efficacy was assessed using the Eczema Area and Severity Index (EASI) and Investigator's Global Assessment (IGA). Indirect response models were applied to link measures of efficacy and functional serum dupilumab concentrations. The covariates on individual placebo-corrected response were assessed. Clinical trial scenarios were simulated to compare E-R relationships across age groups. Safety was not explored. RESULTS After correcting for differences in placebo response and dupilumab exposure: 1) older age, higher body weight, lower baseline thymus and activation-regulated chemokine, and Asian race were associated with slightly lower EASI response, and no clear covariates were identified on IGA response; 2) clinical trial simulations generally showed slightly higher response at a given dupilumab concentration in children compared to adults and adolescents with severe and moderate AD. CONCLUSIONS The collectively tested covariates explain some of the variability in dupilumab response in patients with AD. Patients in all age groups showed adequate response to dupilumab; however, children showed slightly higher drug effects compared to adults and adolescents at equivalent concentrations.

Abstract
INTRODUCTION Atopic dermatitis (AD) is heterogeneous in distribution pattern and clinical features. This analysis assessed the effect of dupilumab on the extent and severity of AD across various signs (erythema, edema/papulation, excoriation, lichenification) in different anatomical regions (head and neck, trunk, upper extremities, lower extremities) in patients aged 6 months to 5 years. METHODS In LIBERTY AD PRESCHOOL, a double-blind, placebo-controlled, phase III clinical trial, children aged 6 months to 5 years with moderate-to-severe AD were randomized 1:1 to subcutaneous dupilumab or placebo with concomitant low-potency topical corticosteroids (TCS) every 4 weeks for 16 weeks. Changes in AD signs across anatomical regions were assessed using unweighted Eczema Area and Severity Index (EASI) body region scores. RESULTS Overall, 162 patients were randomized to dupilumab (n = 83) or placebo (n = 79). A significant improvement in least squares mean EASI area score was seen by week 2 in all four anatomical regions (P < 0.0001 for dupilumab vs. placebo) and sustained throughout treatment. Least squares mean EASI sign scores in erythema, excoriations, and infiltration/papulation showed significant improvement by week 2 in all regions (P < 0.001), while lichenification showed significant improvement in all regions by week 4 (P < 0.001). CONCLUSION Dupilumab use with concomitant low-potency TCS treatment resulted in rapid and consistent improvement in AD signs in all anatomical regions, in patients aged 6 months to 5 years with moderate-to-severe AD.

Abstract
BACKGROUND Children with severe atopic dermatitis (AD) have a multidimensional disease burden. OBJECTIVE Here we assess the clinically meaningful improvements in AD signs, symptoms, and quality of life (QoL) in children aged 6-11 years with severe AD treated with dupilumab compared with placebo. METHODS R668-AD-1652 LIBERTY AD PEDS was a randomized, double-blinded, placebo-controlled, parallel-group, phase III clinical trial of dupilumab with concomitant topical corticosteroids (TCS) in children aged 6-11 years with severe AD. This post hoc analysis focuses on 304 patients receiving either dupilumab or placebo with TCS and assessed the percentage of patients considered responsive to dupilumab treatment at week 16. RESULTS At week 16, almost all patients receiving dupilumab + TCS (95%) demonstrated clinically meaningful improvements in AD signs, symptoms, or QoL compared with placebo + TCS (61%, p < 0.0001). Significant improvements were seen as early as week 2 and sustained through the end of the study in the full analysis set (FAS) and the subgroup of patients with an Investigator's Global Assessment score greater than 1 at week 16. LIMITATIONS Limitations include the post hoc nature of the analysis and that some outcomes were not prespecified; the small number of patients in some subgroups potentially limits generalizability of findings. CONCLUSION Treatment with dupilumab provides significant and sustained improvements within 2 weeks in AD signs, symptoms, and QoL in almost all children with severe AD, including those who did not achieve clear or almost clear skin by week 16.

Abstract
Methotrexate (MTX) is a readily accessible drug, first used in 1948 and employed for a wide variety of indications since then. However, despite widespread off-label use, FDA labeling does not include approved indications for the use of MTX for many inflammatory skin diseases in pediatric patients, including morphea, psoriasis, atopic dermatitis, and alopecia areata, among others. Without published treatment guidelines, some clinicians may be hesitant to use MTX off-label, or uncomfortable prescribing MTX in this population. To address this unmet need, an expert consensus committee was convened to develop evidence- and consensus-based guidelines for use of MTX to treat pediatric inflammatory skin disease. Clinicians with experience and expertise in clinical research, drug development, and treating inflammatory skin disease in pediatric patients with MTX were recruited. Five committees were created based on major topic areas: (1) indications and contraindications, (2) dosing, (3) interactions with immunizations and medications, (4) adverse effects (potential for and management of), and (5) monitoring needs. Pertinent questions were generated and addressed by the relevant committee. The entire group participated in a modified Delphi process to establish agreement on recommendations for each question. The committee developed 46 evidence- and consensus-based recommendations, each with >70% agreement among members, across all five topics. These are presented in tables and text, along with a discussion of supporting literature, and level of evidence. These evidence- and consensus-based recommendations will support safe and effective use of MTX for the underserved population of pediatric patients who may benefit from this valuable, time-honored medication.

Abstract
Abstract
Patients with atopic dermatitis (AD) have an increased risk of infection, including skin infections. Previous studies in children aged 6–11 years and adolescents showed that dupilumab is not associated with an increased risk of overall infections and is associated with a lower incidence of skin infections compared with a placebo. This post-hoc analysis reports the impact of dupilumab treatment on infections, including skin infections, in children aged 6 months to 5 years with moderate-to-severe AD. In LIBERTY AD PRESCHOOL, a double-blind, placebo-controlled trial (NCT03346434, part B), children aged 6 months to 5 years with moderate-to-severe AD (Investigator’s Global Assessment score ≥3) were randomized 1 : 1 to subcutaneous dupilumab every 4 weeks (200 mg if baseline weight was ≥5 to <15 kg, 300 mg if weight was ≥15 to <30 kg) or placebo with concomitant low-potency topical corticosteroids for 16 weeks. Exposure-adjusted rates (patients with ≥1 event per 100 patient-years [nP/100 PY]) and systemic anti-infective medication use (nP/100PY) were used to compare treatment groups. 162 patients were randomized to dupilumab (n = 83) or placebo (n = 79). During the 16-week treatment period, total infections rates were numerically lower in the dupilumab-treated group (nP/100PY: 185.2) compared with the placebo-treated group (nP/100PY: 245.7). Fewer infections of skin-structure and soft tissues were reported in the dupilumab group (nP/100PY: 24.7) compared with the placebo group (nP/100PY: 40.2). Dupilumab-treated patients had significantly lower rates of non-herpetic skin infections (nP/100PY: 42.7) than placebo-treated patients (nP/100PY: 92.7; P < 0.05 vs. placebo). There was no significant difference in rates of herpetic skin infections between the dupilumab (nP/100PY: 20.0) and placebo groups (nP/100PY: 17.1; P = 0.817 vs. placebo). No helminthic infections were reported in either group. Systemic anti-infective medication use was significantly less frequent in the dupilumab group (nP/100PY: 104.7) compared with placebo (nP/100PY: 203.0; P < 0.05 vs. placebo). The overall safety of dupilumab was consistent with the known safety profile. Dupilumab treatment is associated with lower overall infections and significantly lower non-herpetic skin infections than placebo in children aged 6 months to 5 years with moderate-to-severe AD.

Abstract
Abstract
In patients with atopic dermatitis (AD), it is unknown whether suppression of dysregulated type 2 immune cytokines, interleukin-4 and interleukin-13, with dupilumab impacts the risk of viral infections following live attenuated vaccination. Current medical consensus and regulatory labelling recommend completing age-appropriate non-live vaccinations according to immunization guidelines at least 4 weeks prior to starting dupilumab and to avoid the use of live vaccines in patients treated with dupilumab. Phase 3 dupilumab AD clinical trial protocols prohibited the administration of live attenuated vaccines within 4 weeks before the baseline visit and during treatment. For patients in the LIBERTY AD PED open-label extension (OLE; NCT02612454) who required a live attenuated vaccine, the protocol specified that the study drug be discontinued for 12 weeks prior to planned administration and could be re-initiated 4 weeks after vaccine administration. However, one patient in the 16-week LIBERTY AD PRESCHOOL (NCT03346434, part B) study received a live attenuated vaccine with a ≤ 12 weeks gap between dupilumab administration and vaccination and eight patients in the LIBERTY AD PED-OLE received a live attenuated vaccine, four patients were vaccinated with a ≤ 12 weeks gap and four patients > 12 weeks after discontinuing dupilumab. To describe the clinical course of children with moderate-to-severe AD administered a live attenuated vaccine during the LIBERTY AD PRESCHOOL or LIBERTY AD PED-OLE study. Paediatric patients with moderate-to-severe AD who had previously participated in the phase 2 open-label, multicentre, sequential study LIBERTY AD PRESCHOOL (part A; 3 or 6 mg/kg dupilumab single dose) or the randomized, double-blind placebo-controlled phase 3 study LIBERTY AD PRESCHOOL (part B; 200 mg dupilumab every 4 weeks [q4w] if baseline weight 5 to <15 kg, or 300 mg q4w if 15 to <30 kg) were subsequently enrolled into the LIBERTY AD PED-OLE study (200 mg dupilumab q4w if baseline weight 5 to <15 kg, 300 mg q4w if 15 to <30 kg, or 200 mg q2w if 30 to <60 kg). This case series includes nine patients with severe AD at the parent study baseline (Investigator’s Global Assessment score = 4) and Peak Pruritus Numerical Rating Scale (range: 0–10) scores of 5.2 (n = 1), 8 (n = 2), 9 (n = 4) or 10 (n = 2), who were administered a live attenuated vaccine, with or without pause, during dupilumab treatment in the LIBERTY AD PRESCHOOL (part B; n = 1) or LIBERTY AD PED-OLE study (n = 8). Of the nine patients in this case series, eight were male. All were first diagnosed with AD between 0 and 6 months of age and age at enrolment varied from 8 to 56 months old. Dupilumab treatment duration up to the date of vaccination with live attenuated measles, mumps, rubella (MMR) and varicella vaccines (n = 5) or MMR vaccine only (n = 4) ranged from 85 to 840 days. No adverse events (AEs), including serious AEs, treatment-emergent infections and infestations, or serious infections were observed in the 4-week window post-vaccination. In this limited prospective case series of children with moderate-to-severe AD who also received the live attenuated MMR vaccine, with or without live attenuated varicella vaccine, no serious adverse events were observed within 4 weeks or after 4 weeks post-vaccination. Additional research is needed to assess the safety of live attenuated vaccines in patients on dupilumab treatment and to investigate whether dupilumab treatment impacts vaccine efficacy.

Abstract
Abstract
Many systemic therapies used for moderate-to-severe atopic dermatitis (AD) have immunosuppressive properties and necessitate laboratory screening and monitoring, adding to the treatment burden. Previous dupilumab studies in adults, adolescents and children aged 6–11 years with moderate-to-severe AD showed no clinically meaningful adverse changes in laboratory parameters. Here we evaluate hematology and chemistry laboratory safety data for dupilumab-treated children aged 6 months to 5 years with moderate-to-severe atopic dermatitis. Patients aged 6 months to 5 years with inadequately controlled moderate-to-severe AD were enrolled in LIBERTY AD PRESCHOOL (NCT03346434 part B), a randomized, double-blind placebo-controlled phase 3 study. 162 patients were randomized to either dupilumab 200/300 mg every 4 weeks (q4w; N = 83; baseline weight ≥5 <15 kg: 200 mg; ≥15 to <30 kg: 300 mg) or placebo (N = 79) for 16 weeks. From Day –14, all patients initiated standardized treatment with low-potency topical corticosteroids. Laboratory data was collected at baseline, weeks 4 and 16. At baseline, mean (SD) counts of hematology parameters were similar in both treatment groups: haemoglobin (dupilumab: 129.4 gL−1 [12]; placebo: 127.2 gL−1 [11.4]), lymphocyte (dupilumab: 4.6 × 109 L−1 [1.8]; placebo: 4.5 × 109 L−1 [1.7]), basophil (dupilumab: 0.07 × 109 L−1 [0.03]; placebo: 0.07 × 109 L−1 [0.04]), platelet (dupilumab: 397.7 × 109 L−1 [103.2]; placebo: 385.6 × 109 L−1 [112.9]) and eosinophils (dupilumab: 1.1 × 109 L−1 [0.7]; placebo: 1.1 × 109 L−1 [0.7]). Mean (SD) haemoglobin count in the dupilumab (128.4 × gL−1 [11]) and placebo groups (128.2 × gL−1 [11.2]), lymphocyte count in the dupilumab (4.20 × 109 L−1 [2.06]) and placebo groups (4.29 × 109 L−1 [1.52]) and basophil count in the dupilumab (0.07 × 109 L−1 [0.04]) and placebo groups (0.06 × 109 L−1 [0.03]) remained with the normal reference range for this population at week 16. The mean change (SD) in platelet count at week 16 was −16.3 × 109 L−1 (78.5) in the dupilumab group and +17.4 × 109 L−1 (106.6) in the placebo group. In the dupilumab treatment group, the mean eosinophil count increased at week 4 (mean change from baseline [SD]; + 0.48 × 109 L−1 [1.8]) and trended downward by week 16 (+0.31 × 109 L−1 [1.4]) while minimal changes were noted in the placebo group at week 4 (0.1 × 109 L−1 [0.7]) and week 16 (−0.2 × 109 L−1 [0.7]). The values for creatine kinase, alkaline phosphatase, lactate dehydrogenase, blood urea nitrogen, albumin and protein at week 16 remained within the normal reference range in all treatment groups. Two patients in the dupilumab 200/300 mg q4w arm of this study reported treatment-emergent adverse events of severe and moderate eosinophilia. Neither event was associated with clinical symptoms nor led to the discontinuation of the study treatment. No clinically meaningful changes in hematology and chemistry parameters in children aged 6 months to 5 years with moderate-to-severe AD were seen with 16 weeks of dupilumab treatment. These data demonstrate that, as with adults, adolescents and older children, routine laboratory monitoring is unnecessary in this younger population. Dupilumab was generally well tolerated with an acceptable safety profile.

Abstract
Abstract
Continuous use of several traditional systemic atopic dermatitis (AD) treatments in pediatric patients is not recommended due to safety concerns and lack of long-term efficacy data. Children aged 6 months to 5 years with moderate-to-severe AD who had participated in the 16-week, double-blind, phase 3 LIBERTY AD PRESCHOOL trial (NCT03346434, part B; parent study) were enrolled in an open-label extension (OLE) study (NCT02612454). Patients received subcutaneous dupilumab every 4 weeks (200 mg for children weighing 5 to <15 kg; 300 mg for 15 to <30 kg). Topical AD treatments were allowed. Relative to the parent study baseline, mean percentage changes (± standard error) in Eczema Area and Severity Index score were −41.6 (±4.6) and −54.0 (±3.2) at OLE baseline, −74.5 (±3.7) and −81.7 (±1.8) at week 16, and −85.6 (±3.5) and −86.4 (±2.2) at week 52 in the 200 and 300 mg dupilumab groups, respectively. The number of patients (%) achieving an Investigator’s Global Assessment score of 0/1 increased from OLE baseline (6/61 [9.8%] and 15/116 [12.9%]) to week 16 (22/58 [37.9%] and 35/115 [30.4%]), and at week 52 (16/34 [47.1%] and 18/54 [33.3%]) in the 200 and 300 mg dupilumab groups, respectively. The overall safety of dupilumab treatment administered for up to 1 year was consistent with the known dupilumab safety profile. Dupilumab treatment for 1 year provides sustained improvement in signs of AD in patients aged 6 months to 5 years with moderate-to-severe AD.

Abstract
BACKGROUND AND OBJECTIVE Previous studies of dupilumab for the treatment of moderate-to-severe atopic dermatitis in adults and adolescents, and severe atopic dermatitis in children aged 6 to < 12 years demonstrate no clinically important changes in laboratory parameters. The objective of this study was to assess laboratory outcomes in children aged 6 months to < 6 years with moderate-to-severe atopic dermatitis treated with dupilumab. METHODS In this randomized, placebo-controlled, phase III trial of dupilumab, 161 children aged 6 months to < 6 years with moderate-to-severe atopic dermatitis were enrolled from 31 sites in Europe and North America and randomized 1:1 to receive subcutaneous placebo or dupilumab (5 kg to < 15 kg: 200 mg; 15 kg to < 30 kg: 300 mg) every 4 weeks plus topical corticosteroids for 16 weeks. Hematology, serum chemistry, and urinalysis assessments were analyzed on blood and urine samples collected at screening and weeks 4 and 16; descriptive statistics are provided. RESULTS No clinically meaningful changes in laboratory parameters were observed. While two cases of eosinophilia and one case each of neutropenia and leukocytosis were reported as treatment-emergent adverse events in the dupilumab plus topical corticosteroids group, these events were not associated with clinical symptoms and did not lead to treatment discontinuation or study withdrawal. CONCLUSIONS These results suggest that routine laboratory monitoring of children aged 6 months to < 6 years treated with dupilumab plus topical corticosteroids is not required. Limitations of this study include short study duration, and exclusion of patients with abnormalities in laboratory test results at screening.

Abstract
BACKGROUND Current systemic treatments for children younger than 6 years with moderate-to-severe atopic dermatitis that is uncontrolled with topical therapies might have suboptimal efficacy and safety. Dupilumab is approved for older children and adults with atopic dermatitis and for other type 2 inflammatory conditions. We aimed to evaluate efficacy and safety of dupilumab with concomitant low-potency topical corticosteroids in children aged 6 months to younger than 6 years with moderate-to-severe atopic dermatitis. METHODS This randomised, double-blind, placebo-controlled, parallel-group, phase 3 trial was conducted in 31 hospitals, clinics, and academic institutions in Europe and North America. Eligible patients were aged 6 months to younger than 6 years, with moderate-to-severe atopic dermatitis (Investigator's Global Assessment [IGA] score 3-4) diagnosed according to consensus criteria of the American Academy of Dermatology, and an inadequate response to topical corticosteroids. Patients were randomly assigned (1:1) to subcutaneous placebo or dupilumab (bodyweight ≥5 kg to <15 kg: 200 mg; bodyweight ≥15 kg to <30 kg: 300 mg) every 4 weeks plus low-potency topical corticosteroids (hydrocortisone acetate 1% cream) for 16 weeks. Randomisation was stratified by age, baseline bodyweight, and region. Patient allocation was done via a central interactive web response system, and treatment allocation was masked. The primary endpoint at week 16 was the proportion of patients with IGA score 0-1 (clear or almost clear skin). The key secondary endpoint (coprimary endpoint for the EU and EU reference market) at week 16 was the proportion of patients with at least a 75% improvement from baseline in Eczema Area and Severity Index (EASI-75). Primary analyses were done in the full analysis set (ie, all randomly assigned patients, as randomly assigned) and safety analyses were done in all patients who received any study drug. This study was registered with ClinicalTrials.gov, NCT03346434. FINDINGS Between June 30, 2020, and Feb 12, 2021, 197 patients were screened for eligibility, 162 of whom were randomly assigned to receive dupilumab (n=83) or placebo (n=79) plus topical corticosteroids. At week 16, significantly more patients in the dupilumab group than in the placebo group had IGA 0-1 (23 [28%] vs three [4%], difference 24% [95% CI 13-34]; p<0·0001) and EASI-75 (44 [53%] vs eight [11%], difference 42% [95% CI 29-55]; p<0·0001). Overall prevalence of adverse events was similar in the dupilumab group (53 [64%] of 83 patients) and placebo group (58 [74%] of 78 patients). Conjunctivitis incidence was higher in the dupilumab group (four [5%]) than the placebo group (none). No dupilumab-related adverse events were serious or led to treatment discontinuation. INTERPRETATION Dupilumab significantly improved atopic dermatitis signs and symptoms versus placebo in children younger than 6 years. Dupilumab was well tolerated and showed an acceptable safety profile, similar to results in older children and adults. FUNDING Sanofi and Regeneron Pharmaceuticals.

Abstract
BACKGROUND/OBJECTIVE Patients with moderate-to-severe atopic dermatitis (AD) have increased risk of cutaneous and extracutaneous infections. Dupilumab has previously been associated with reduced risk of serious/severe infections and non-herpetic skin infections in adults with moderate-to-severe AD. This analysis assessed infection rates with dupilumab versus placebo in pediatric patients with moderate-to-severe and severe AD participating in clinical trials. METHODS This is a pooled analysis from two 16-week, randomized, placebo-controlled, phase 3 clinical trials of dupilumab: monotherapy in adolescents aged 12-17 years with moderate-to-severe AD (LIBERTY AD ADOL, NCT03054428) and with concomitant topical corticosteroids in children aged 6-11 years with severe AD (LIBERTY AD PEDS, NCT03345914). Data were pooled according to treatment received: placebo/approved dupilumab doses/other studied dupilumab doses/all dupilumab doses. Exposure-adjusted rates (patients with ≥1 event per 100 patient-years [nP/100 PY]) were used to compare treatment groups. RESULTS Overall, 612 patients were included: 205 received placebo and 407 received dupilumab (261 received approved dupilumab doses and 146 received other studied dupilumab doses). Overall infection rates were numerically lower with dupilumab versus placebo (nP/100 PY: placebo, 227; approved dupilumab, 173; other dupilumab, 206; all dupilumab, 184). Total skin infections were numerically less frequent in all dupilumab-treated groups versus placebo (nP/100 PY: placebo, 67; approved dupilumab, 30; other dupilumab, 46; all dupilumab, 36). CONCLUSIONS These data suggest that dupilumab treatment in children and adolescents with AD does not increase infection risk overall and is associated with lower rates of skin infections compared with placebo.

Abstract
The beginning of the end (BOTE) sign has been proposed to describe well-recognized clinical signs of inflammation (including erythema, induration, and scale) that predict imminent resolution of molluscum contagiosum (MC). This phenomenon has never been prospectively studied. An integrated analysis of two prospective, 12-week, randomized, double-blind clinical trials of topical nitric oxide–releasing SB206 gel evaluated an association between BOTE sign and MC lesion reduction. Of 707 randomized patients, ~80% exhibited BOTE signs regardless of treatment assignment. At week 12, MC lesion counts decreased from baseline by 50.7% for baseline BOTE+ versus 29.1% for BOTE– (P = 0.0015) vehicle-treated patients compared with a 63.3% decrease for baseline BOTE+ versus 51.7% for BOTE– (P = 0.0194) SB206-treated patients. Among vehicle-treated patients, 48 (22.3%) who were never BOTE+ had an 18.5% reduction from baseline in MC lesion counts versus a 34.0% reduction in 165 patients (76.7%) who experienced BOTE at any time, suggesting that the projected duration of lesion clearance for patients with 18–20 MC lesions is 15 months for BOTE– versus 6 months for BOTE+ patients. Patients who were both BOTE+ and treated with SB206 had the greatest reduction in MC lesion count. SB206 may trigger BOTE signs and shorten the duration of MC infection. The two studies whose data are analyzed in this study are registered at ClinicalTrials.gov with the identifiers NCT03927703 and NCT03927716

Abstract
Dupilumab demonstrated efficacy with an acceptable safety profile in two randomized, double-blind, placebo-controlled, parallel-group, phase III trials in adolescents (12-17 years; LIBERTY AD ADOL) and children (6-11 years; LIBERTY AD PEDS) with atopic dermatitis (AD) treated for 16 weeks. Here, we present the pharmacokinetic profiles and exposure-response (E-R) relationships of dupilumab that guided the posology in these populations. A total of 251 adolescent patients with moderate-to-severe AD were randomized to subcutaneous dupilumab monotherapy every 2 weeks (q2w; 200 mg q2w, baseline weight < 60 kg; 300 mg q2w, ≥ 60 kg), dupilumab 300 mg every 4 weeks (q4w; non-weight tiered), or placebo; 367 children with severe AD were randomized to dupilumab q2w (100 mg q2w, baseline weight < 30 kg; 200 mg q2w, ≥ 30 kg), dupilumab 300 mg q4w, or placebo. Children received concomitant topical corticosteroids in addition to dupilumab, and loading doses were administered at the start of therapy. Mean dupilumab trough concentrations at week 16 for weight subcategories in each dosing regimen were compared with adult exposures for the approved dupilumab 300 mg q2w regimen. Positive E-R relationships were demonstrated between dupilumab trough concentrations and AD outcome measures across patient populations and regimens; no relationship was observed with treatment-emergent conjunctivitis. Based on these analyses, a weight-tiered posology was proposed for adolescents (200/300 mg q2w in patients 30-< 60 kg/≥ 60 kg) and children (300 mg q4w in patients 15-< 30 kg, 200 mg q2w in patients 30-< 60 kg) with moderate-to-severe AD.

Abstract
BACKGROUND Patients with atopic dermatitis (AD) are considered at increased risk of developing other type 2 inflammatory diseases. However, real-world evidence based on large US commercially insured pediatric populations is scarce. OBJECTIVE To use a large US claims database (IBM® MarketScan® 2013-2017) to assess prevalence and incidence of type 2 inflammatory diseases in pediatric AD patients. METHODS Pediatric AD patients were matched 1:1 to non-AD patients. Prevalence was assessed for conjunctivitis, rhinitis, urticaria, asthma, eosinophilic esophagitis and chronic rhinosinusitis/nasal polyps, 12 months post-index date (first AD diagnosis date for AD patients; a randomly selected outpatient visit for control patients). Incidence of other type 2 inflammatory diseases post-index was assessed among patients 0-2 years old. RESULTS 244,776 AD and matched non-AD patients were selected. The prevalence and incidence of type 2 inflammatory diseases were higher among AD patients. Overall, the prevalence more than doubled for asthma, eosinophilic esophagitis, urticaria, and rhinitis, and increased with AD severity. LIMITATIONS AD identification based on billing diagnoses; observation period of only 12 months; limited to commercially insured patients CONCLUSION: The burden of type 2 inflammatory diseases in pediatric AD patients is substantial, highlighting the need to optimize management of AD and its numerous associated morbidities.

Abstract
Background Laboratory testing is typically required for patients with atopic dermatitis (AD) treated with systemic immunosuppressants. A previous analysis of laboratory outcomes in randomized, double-blinded, placebo-controlled clinical trials of dupilumab in adults with moderate-to-severe AD found no clinically important changes in hematologic, serum chemistry, and urinalysis parameters, supporting the use of dupilumab without routine laboratory monitoring. Objective The aim was to assess laboratory results in adolescents with moderate-to-severe AD treated with dupilumab in a phase 3, randomized, double-blind, placebo-controlled trial. Methods Adolescents aged ≥ 12 to < 18 years with moderate-to-severe AD were randomized 1:1:1 to subcutaneous dupilumab 200/300 mg every 2 weeks (q2w) (200 mg for patients < 60 kg at baseline; 300 mg for patients ≥ 60 kg at baseline); dupilumab 300 mg every 4 weeks (q4w); or placebo for 16 weeks. Laboratory evaluations included hematology, serum chemistry, and urinalysis parameters. Results Of 251 patients enrolled in the study, 250 received treatment and were included in the analysis. 4.7%, 2.4%, and 4.8% of patients receiving placebo, dupilumab 200/300 mg q2w, and dupilumab 300 mg q4w, respectively, had laboratory abnormalities reported as treatment-emergent adverse events, none of which prompted discontinuation of study treatment or study withdrawal. Mean eosinophil counts were elevated at baseline in all treatment groups. Patients in both dupilumab regimens, but not the placebo group, showed mild transient increases in mean eosinophil counts above baseline that returned to near-baseline values by week 16. Mean levels of lactate dehydrogenase trended towards the upper limit of normal at baseline and decreased with treatment; greater decreases were seen in dupilumab-treated patients than placebo-treated patients. There were no meaningful changes in other laboratory parameters, and none of the laboratory abnormalities were clinically significant. Conclusion No clinically meaningful changes in laboratory parameters were seen in adolescents, similar to that observed in adults. The findings of this study indicate no routine laboratory monitoring is required in this population prior to or during dupilumab treatment. Trial Registration ClinicalTrials.gov: NCT03054428.

Abstract
BACKGROUND Dupilumab has demonstrated efficacy and acceptable safety in adults and children (aged 6-17 years) with moderate-to-severe atopic dermatitis (AD), but effective systemic therapy with a favorable risk-benefit profile in younger children remains a significant unmet need. OBJECTIVES To determine the pharmacokinetics, safety and efficacy of single-dose dupilumab in children with severe AD aged ≥6 months to <6 years. METHODS This open-label, multicenter, phase 2, sequential, two-age cohort, two-dose level study (LIBERTY AD PRE-SCHOOL; NCT03346434) included an initial cohort of older children aged ≥2 to <6 years, followed by a younger cohort aged ≥6 months to <2 years. Pharmacokinetic sampling, safety monitoring and efficacy assessments were performed during the 4-week period after a single subcutaneous injection of dupilumab, in two sequential dosing groups (3 mg/kg, then 6 mg/kg). The use of standardized, low-to-medium potency topical corticosteroids was allowed. RESULTS Forty patients were enrolled (20/age cohort, 10/dose level within a cohort) between December 20, 2017 and July 22, 2019. Within each age cohort, pharmacokinetic exposures after a single injection of dupilumab increased in a greater than dose-proportional manner. At week 3, treatment with 3 and 6 mg/kg dupilumab reduced scores of mean Eczema Area and Severity Index by -44.6% and -49.7% (older cohort) and -42.7% and -38.8% (younger cohort), and mean Peak Pruritus NRS scores by -22.9% and -44.7% (older cohort) and -11.1% and -18.2% (younger cohort), respectively. At week 4, improvements in most efficacy outcomes diminished in both age groups, particularly with the lower dose. The safety profile was comparable to that seen in adults, adolescents and children. CONCLUSIONS Single-dose dupilumab was generally well tolerated and substantially reduced clinical signs/symptoms of AD. Slightly better responses were seen in older than younger children. The pharmacokinetics of dupilumab were non-linear, consistent with previous studies in adults and adolescents.

Abstract
Importance Adolescents 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. Objective To assess the efficacy and safety of dupilumab monotherapy in adolescents with moderate to severe inadequately controlled AD. Design, Setting, and Participants A 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. Interventions Patients 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 Measures Proportion 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. Results A 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 Relevance In 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 Registration ClinicalTrials.gov identifier: NCT03054428.

Abstract
BACKGROUND/OBJECTIVES The COVID-19 pandemic has raised questions about the approach to management of systemic immunosuppressive therapies for dermatologic indications in children. Change to: Given the absence of data to address concerns related to SARS-CoV-2 infection and systemic immunosuppressive therapies in an evidence-based manner, a Pediatric Dermatology COVID-19 Response Task Force (PDCRTF) was assembled to offer time-sensitive guidance for clinicians. METHODS A survey was distributed to an expert panel of 37 pediatric dermatologists on the PDCRTF to assess expert opinion and current practice related to three primary domains of systemic therapy: initiation, continuation, and laboratory monitoring. RESULTS Nearly all respondents (97%) reported that the COVID-19 pandemic had impacted their decision to initiate immunosuppressive medications. The majority of pediatric dermatologists (87%) reported that they were pausing or reducing the frequency of laboratory monitoring for certain immunosuppressive medications. In asymptomatic patients, continuing therapy was the most popular choice across all medications queried. The majority agreed that patients on immunosuppressive medications who have a household exposure to COVID-19 or test positive for new infection should temporarily discontinue systemic and biologic medications, with the exception of systemic steroids, which may require tapering. CONCLUSIONS The ultimate decision regarding initiation, continuation, and laboratory monitoring of immunosuppressive therapy during the pandemic requires careful deliberation, consideration of the little evidence available, and discussion with families. Consideration of an individual's adherence to COVID-19 preventive measures, risk of exposure, and the potential severity if infected must be weighed against the dermatological disease, medication, and risks to the patient of tapering or discontinuing therapies.

Abstract
PHACE syndrome classically presents with a large, segmental facial infantile hemangioma (IH) associated with structural and vascular abnormalities involving the head and neck, heart, and eyes. We evaluated an infant who presented with ptosis caused by a clinically subtle, deep right-sided periorbital IH identified on MRI that also incidentally revealed hypoplasia of the right common carotid and right internal carotid arteries, supporting a diagnosis of PHACE syndrome. She subsequently developed acute-onset, transient right-sided facial erythema without anisocoria, triggered by feeding and emotional stress. We believe this represents a Frey syndrome-like developmental dysautonomia, previously unreported in association with PHACE syndrome, suggesting an associated defect in neurovascular embryogenesis.

Abstract
Background Atopic dermatitis is a chronic inflammatory condition with substantial burden and limited treatment options for adolescents with moderate-to-severe disease. Significantly more patients treated with dupilumab vs. placebo achieved Investigator’s Global Assessment 0/1 at week 16. Objective The objective of this study was to assess the impact of dupilumab treatment vs. placebo on the achievement of clinically meaningful improvements in atopic dermatitis signs, symptoms and quality of life. Methods R668-AD-1526 LIBERTY AD ADOL was a randomized, double-blinded, parallel-group, phase III clinical trial. Two hundred and fifty-one adolescents with moderate-to-severe atopic dermatitis received dupilumab 300 mg every 4 weeks (q4w; n = 84), dupilumab 200 or 300 mg every 2 weeks (q2w; n = 82), or placebo (n = 85). A post-hoc subgroup analysis was performed on 214 patients with Investigator’s Global Assessment > 1 at week 16. Measures of atopic dermatitis signs, symptoms, and quality of life were assessed. Clinically meaningful improvement in one or more of three domains of signs, symptoms, and quality of life was defined as an improvement of ≥ 50% in Eczema Area and Severity Index, ≥ 3 points in Peak Pruritus Numerical Rating Scale, or ≥ 6 points in the Children’s Dermatology Life Quality Index from baseline. Results Of patients receiving dupilumab q2w, 80.5% [66/82] experienced clinically meaningful improvements in atopic dermatitis signs, symptoms, or quality of life at week 16 (vs. placebo, 20/85 [23.5%], difference 57.0% [95% confidence interval 44.5–69.4]; q4w vs. placebo, 53/84 [63.1%], difference 39.6% [95% confidence interval 25.9–53.3]; both p < 0.0001). Results were similar in adolescents with Investigator’s Global Assessment > 1 at week 16 (q2w, 46/62 [74.2%] vs. placebo, 18/83 [21.7%], difference 52.5% [95% confidence interval 38.5–66.6]; q4w, 38/69 [55.1%] vs. placebo, difference 33.4% [95% confidence interval 18.7–48.1]; both p < 0.0001). Conclusions Dupilumab provided clinically meaningful improvements in signs, symptoms, and quality of life in adolescents with moderate-to-severe atopic dermatitis among patients with Investigator’s Global Assessment > 1 at week 16. Treatment responses should be interpreted in the context of such clinically relevant patient-reported outcome measures. Trial Registration ClinicalTrials.gov; NCT03054428.

Abstract
BACKGROUND Although a variety of ablative, topical, and systemic therapies are used for molluscum contagiosum (MC), none has been well studied or approved by the US Food and Drug Administration. OBJECTIVES To compare the efficacy and tolerability of topical SB206 (berdazimer sodium gel coadministered with hydrogel) with vehicle. METHODS A 12-week, phase 2, multicenter, randomized, double-blind, vehicle-controlled clinical trial of topical SB206. RESULTS A total of 256 patients (mean age, approximately 7 years) participated. Of patients who completed 12 weeks of treatment (n = 217), all MC lesions cleared in 20.0% of patients who received vehicle compared with 13.2%, 41.0%, and 35.1% of patients treated with twice daily SB206 4%, 8%, and 12%, respectively, and 41.9% of patients treated with once daily SB206 12%. Application-site erythema occurred in 10.6% of patients treated with SB206. Application-site reactions were the most common adverse events leading to treatment discontinuation, affecting 2 patients (approximately 4%) in each of the SB206 4%, 8%, and 12% twice daily groups and 0 patients in the vehicle or SB206 12% once daily groups. LIMITATIONS A larger study is needed to confirm the efficacy of SB206 12% once daily and provide additional safety assessments. CONCLUSION Of the doses studied, SB206 12% applied once daily provided the best balance between MC lesion clearance and tolerability for evaluation in a larger study.

Abstract
BACKGROUND Real-world evidence on treatment patterns of pediatric patients with atopic dermatitis (AD) is sparse. OBJECTIVE To assess current treatment patterns in pediatric AD patients. METHODS Retrospective observational analysis of commercial insurance and Medicaid administrative claims data (January 2011-December 2016) for pediatric AD patients, stratified by age and provider type. RESULTS The analytic sample comprised 607,258 pediatric AD patients. Median observation period was 30.3 months. Overall, 78.6% were prescribed ≥1 AD medication; 86.7% were prescribed topical corticosteroids, and 5.4% were prescribed a calcineurin inhibitor. Systemic corticosteroids (SCSs) were prescribed for 24.4% of patients, 51.8% of whom did not have asthma or allergic comorbidities. Of the 46.6% prescribed an antihistamine and 16.2% prescribed montelukast, 62.0% and 41.3%, respectively, did not have asthma or allergic comorbidities. Systemic immunosuppressants were rarely prescribed (<0.5%). Higher potency topical corticosteroid and SCS use increased with age. Treatment patterns varied by provider type; specialists were more likely to prescribe higher potency topicals and/or systemics, regardless of patient age. A minority of patients were treated by or referred to a specialist. LIMITATIONS Identification of AD patients relied on billing diagnoses; the disease severity was proxied by the treatment prescribed. CONCLUSION Results indicate that SCSs, despite known risks, and other medications with disproven efficacy in AD are frequently prescribed, suggesting a need for safer and more effective alternatives.

Abstract
Studies have suggested there is a shortage of pediatric dermatologists in the United States, but the workforce has not been well defined. The Society for Pediatric Dermatology (SPD) Workforce Committee sought to characterize the US pediatric dermatology workforce with a nine-question survey, sent to all 484 US SPD members in December 2016. The response rate was 30%. Most pediatric dermatologists were practicing in major metropolitan markets, seeing an average of 80 patients a week with an average 6-week wait time. These findings indicate that geographic maldistribution and long wait times for new patient appointments remain substantial hurdles for adequate access to subspecialty pediatric dermatology care.

Abstract
INTRODUCTION Treatment guidelines endorse a variety of strategies for atopic dermatitis (AD) which may vary from published data and clinical practice patterns. The objective of this review was to quantify the volume of available medical literature supporting pediatric AD treatments and compare these patterns to those recommended by published guidelines and/or clinical practice patterns. METHODS Searches of Embase (2005-2016) and abstracts from selected meetings (2014-2016) related to AD treatment in patients younger than 17 years of age yielded references that were assessed by study design, primary treatment, age groups, and AD severity. RESULTS Published literature partially supports clinical guidelines, with emollients and topical medications being the most investigated. There were disproportionately more publications for topical calcineurin inhibitors (TCI) compared with topical corticosteroids (TCS); however, the search interval may have biased the results toward treatments approved near the beginning of the time frame. In contrast, publications documenting clinical practice patterns reflect greater use of emollients and TCS (over TCI), as well as systemic corticosteroids. Data is relatively limited for long-term and combination treatment, treatment of severe AD, and patients younger than 2 years of age, and completely lacking for systemic corticosteroids. CONCLUSION This scoping review demonstrates that available medical literature largely supports published guidelines for topical therapy; however, clinical practice patterns are less aligned. There is a lack of data for older, more frequently used generic treatments, including oral antihistamines, oral antibiotics, and systemic corticosteroids. Overall, literature is lacking for long-term treatment, treatment for patients younger than 2 years of age, and for systemic treatment for severe disease. FUNDING Regeneron Pharmaceuticals Inc.

Abstract
Atopic dermatitis is the most common chronic skin disease, and it primarily affects children. Although atopic dermatitis (AD) has the highest effect on burden of skin disease, no high-level studies have defined optimal therapy for severe disease. Corticosteroids have been used to treat AD since the 1950s and remain the only systemic medication with Food and Drug Administration approval for this indication in children, despite published guidelines of care that recommend against this option. Several clinical trials with level 1 evidence have supported the use of topical treatments for mild to moderate atopic dermatitis in adults and children, but these trials have had little consistency in protocol design. Consensus recommendations will help standardize clinical development and trial design for children. The Food and Drug Administration issues guidance documents for industry as a source for "the Agency's current thinking on a particular subject." Although they are nonbinding, industry considers these documents to be the standard for clinical development and trial design. Our consensus group is the first to specifically address clinical trial design in this population. We developed a draft guidance document for industry, Developing Drugs for Treatment of Atopic Dermatitis in Children (≥3 months to <18 years of age). This draft guidance has been submitted to the Food and Drug Administration based on a provision in the Federal Register (Good Guidance Practices).

Abstract
New-onset psoriasis in patients receiving tumor necrosis factor inhibitors is well recognized in children and adults. We describe three children who underwent cardiac transplantation and developed an analogous form of paradoxic eczema occurring 2-48 months after starting systemic tacrolimus, a drug widely used topically to treat eczema. Anecdotal reports and our experience suggest that tacrolimus taper with alternative systemic antirejection immunosuppressant may lead to skin clearance. Pending additional insight, treatment should include optimizing skin barrier function, minimizing microbial and allergic triggers, and coordinating care to choose the best-tolerated systemic immunosuppressant regimen at the lowest effective dose.

Abstract
The association between guttate psoriasis and infection with group A Streptococcus (GAS) has been well established in the medical literature. However, responses to treatments aimed at GAS eradication such as systemic antibiotics or tonsillectomy are inconsistent. Further complicating treatment recommendations for a disease with a suspected microbial trigger, the standard therapy for severe psoriasis is with systemic immunosuppressant medications. This case report illustrates the role of GAS as a trigger for acute onset severe psoriasis in a child whose skin disease initially worsened with a trial of methotrexate. An immune evaluation confirmed a co-existing selective antibody deficiency. Subsequent treatment with intravenous immune globulin dramatically improved his underlying immune function and decreased GAS infections. This improvement in overall immune function and decrease in GAS infections cleared his skin disease. An interval change in formulation to subcutaneous immune globulin was not as effective.

Abstract
BACKGROUND Many clinicians have concerns about the safety of atopic dermatitis (AD) treatments, particularly in children requiring long-term daily maintenance therapy. Topical corticosteroids (TCS) have been widely used for >5 decades. Long-term TCS monotherapy has been associated with adverse cutaneous effects including atrophy, rebound flares, and increased percutaneous absorption with potential for adverse systemic effects. Topical calcineurin inhibitors (TCIs), tacrolimus and pimecrolimus, available for 1-2 decades, are not associated with atrophy or increased percutaneous absorption after prolonged use and have much lower potential for systemic effects. However, since 2006 TCIs have carried a controversial Boxed Warning based on a theoretical risk of malignancy (eg, skin and lymphoma) that has limited TCI use for standard-of-care maintenance therapy. METHODS A comparative systematic search of PubMed was done for long-term (≥12 week) clinical trials of TCS or TCI treatment in patients <12 years with AD. Citations were reviewed for inclusion based on MeSH terms, abstracts, and relevant article text. Studies were excluded if they did not encompass subjects <12 years, or were <12 weeks' duration, retrospective, meta-analyses, or limited to anecdotal case reports. RESULTS Of 27 trials meeting criteria, 21 included 5825 pediatric patients treated with TCIs, and 6 included 1999 patients treated with TCS. TCS studies were limited to low- to mid-potency products, and all but one study lacked a vehicle control. Eight TCI studies were vehicle-controlled, and safety data were well reported, with ≤5 % of patients reporting discontinuation due to adverse effects (DAEs). Cutaneous and systemic adverse events (AEs) were similar in TCI and vehicle groups, with no reports of lymphoma. Safety data in TCS trials were less well reported. DAE incidence was addressed in just 2 trials, and systemic and cutaneous AEs were mostly unreported. CONCLUSIONS Data supporting long-term use of TCIs are robust, documenting safety and efficacy, while data supporting long-term TCS use are limited to low- to mid-potency products. Our review identifies a lack of information on the safety of commonly prescribed, long-term monotherapy with mid- to high-potency TCS in pediatric AD, and supports standard-of-care maintenance therapy with TCIs and intermittent use of low- to mid-potency TCS for flares.

Abstract
BACKGROUND Atopic dermatitis (AD) is the most common chronic pediatric skin disease, and it can profoundly affect a family's quality of life. Children with flaring AD often seek treatment in emergency departments (EDs), which leads to expensive care and ineffective long-term disease control. OBJECTIVES The objective of the current study was to determine the effect of a pediatric dermatology service (PDS) on ED use and charges and of disease outcomes for patients diagnosed with AD before and after establishing an intramural PDS. METHODS This retrospective study reviewed electronic medical records of patients presenting to an urban children's hospital ED with diagnoses encompassing the terms AD, eczema, dermatitis and International Classification of Diseases, Ninth Revision (ICD-9) codes 691.8 and 692.9 during the year before (pre-PDS period) and 3 years after establishing a PDS. RESULTS There were 205 ED visits for dermatitis in the pre-PDS period and 130 in the with-PDS period, a 36.6% decrease (p < 0.001). In the pre-PDS period, 53.7% (n = 110/205) of patients presenting to the ED had moderate dermatitis, compared with 26.2% (n = 34/130) in the with-PDS period, a 69.1% decrease (p < 0.001). Total ED charges were $142,885 for the pre-PDS period and $90,610 for the with-PDS period, a $52,275 decrease. CONCLUSIONS This study provides a salient example of achieving the triple aim of health care reform: improving health outcomes (decreased ED visits) improving the patient experience (transitioning care from the ED to the more appropriate ambulatory clinical setting), and decreasing the cost of care (decreased ED charges).

Abstract
Atopic dermatitis (AD) is one of the most common skin diseases affecting infants and children. A smaller subset of adults has persistent or new-onset AD. AD is characterized by pruritus, erythema, induration, and scale, but these features are also typical of several other conditions that can mimic, coexist with, or complicate AD. These include inflammatory skin conditions, infections, infestations, malignancies, genetic disorders, immunodeficiency disorders, nutritional disorders, graft-versus-host disease, and drug eruptions. Familiarity of the spectrum of these diseases and their distinguishing features is critical for correct and timely diagnosis and optimal treatment.

Abstract
Up to 30% percent of pediatric primary care visits include a skin-related problem, and referrals are hampered by appointment wait times among the longest of any pediatric subspecialty. Despite the clear demand for pediatric dermatologists, there has been a long-standing shortage of providers, leaving dermatology as one of the most underserved pediatric subspecialties. Another consequence of the workforce shortage is the limited opportunity for pediatric dermatology training for residents and postgraduate general pediatricians and dermatologists. This review includes the evolution of the subspecialty from conception through the present, along with obstacles to workforce expansion and potential solutions to improve access to care for children with skin diseases.

Abstract
We report a 2-month-old boy with a painful ulcerated hemangioma on the lower mucosal lip extending to the vermillion border that caused feeding difficulty. It was successfully treated with topical brimonidine 0.2% and timolol 0.5%, a combination selective α2 -adrenergic agonist and nonselective β-blocker. After 6 weeks of treatment, the lesion reepithelialized and the patient's symptoms and functional complications resolved. Brimonidine 0.2% timolol 0.5% ophthalmic solution is an emerging alternative treatment for hemangiomas, offering the potential to target hemangioma growth through two synergistic mechanisms (β-inhibition and α2 -agonism) that may be especially effective for ulcerated lesions, the most common complication of infantile hemangiomas.

Abstract
Ankyloblepharon-ectodermal defects-cleft lip/palate (AEC) syndrome is a rare monogenetic disorder that is characterized by severe abnormalities in ectoderm-derived tissues, such as skin and its appendages. A major cause of morbidity among affected infants is severe and chronic skin erosions. Currently, supportive care is the only available treatment option for AEC patients. Mutations in TP63, a gene that encodes key regulators of epidermal development, are the genetic cause of AEC. However, it is currently not clear how mutations in TP63 lead to the various defects seen in the patients' skin. In this review, we will discuss current knowledge of the AEC disease mechanism obtained by studying patient tissue and genetically engineered mouse models designed to mimic aspects of the disorder. We will then focus on new approaches to model AEC, including the use of patient cells and stem cell technology to replicate the disease in a human tissue culture model. The latter approach will advance our understanding of the disease and will allow for the development of new in vitro systems to identify drugs for the treatment of skin erosions in AEC patients. Further, the use of stem cell technology, in particular induced pluripotent stem cells (iPSC), will enable researchers to develop new therapeutic approaches to treat the disease using the patient's own cells (autologous keratinocyte transplantation) after correction of the disease-causing mutations.

Abstract
OBJECTIVES To target pediatric dermatologists directly in order to evaluate their current demographics and the most important motivating factors that influenced their career choice. Pediatric dermatology is one of the pediatric subspecialties with an inadequate supply to meet current patient needs. STUDY DESIGN A survey was designed to evaluate the training pathway, employment status, participation in teaching, and clinical practice characteristics of pediatric dermatologists. The survey was administered to attendants of the 2010 Society for Pediatric Dermatology annual meeting. Any remaining board certified pediatric dermatologists who had not previously responded were queried via Survey Monkey. RESULTS There was a 71% response rate. The majority chose a career in pediatric dermatology early, often prior to starting a dermatology residency. The vast majority of respondents noted mentorship as the most important influence on their decision to pursue a career in pediatric dermatology. The most common obstacles cited by respondents were financial hardship and resistance of some dermatology programs to accept applicants previously trained in pediatrics. CONCLUSIONS Our survey provides evidence to support the importance of early exposure to the field and, most importantly, to committed pediatric dermatologists who can serve as mentors. This information may be helpful in approaching solutions to the workforce shortage in the field of pediatric dermatology.

Abstract
Acne vulgaris in infants and children often triggers extensive laboratory evaluation out of concern about associated endocrinopathy. Clinical parameters to help guide evaluation of these children have not been defined. This was a retrospective chart review of 24 preadolescent patients with acne and a review of related medical literature. Two age-related subsets were identified: 12 patients who developed acne before the age of 15 months, 75% male, with comedonal and inflammatory lesions; and 12 patients who developed acne between the ages of 2 and 7 years, 75% female, with primarily comedonal lesions. Laboratory evaluation in 13 of the patients was unremarkable. Bone age was advanced in 1 of the 11 children imaged. Premature adrenarche was diagnosed in four patients; all four had additional clinical signs of puberty and growth parameters >90th percentile. None required additional treatment. Our cohort of preadolescent children presenting with acne included an equal number of patients in two distinct subsets: infantile and childhood-onset acne. Literature review identified a rare third subset presenting with acne, signs of advanced puberty, and associated endocrinopathy. There was no evidence of endocrinopathy in our patients with infantile acne. Two-thirds of our patients with childhood-onset acne had no additional clinical signs of puberty and no evidence of endocrinopathy. A focused history and physical examination is sufficient to evaluate the majority of infants and children with acne. Hand X-ray for bone age is a useful screening test. Further evaluation and endocrinology referral are warranted in preadolescents with acne and advanced bone age or additional clinical evidence of early puberty.
