Dupilumab with concomitant topical corticosteroid treatment in adults with atopic dermatitis with an inadequate response or intolerance to ciclosporin A or when this treatment is medically inadvisable: a placebo-controlled, randomized phase III clinical t

A systematic review investigating the proportion of clinical images shared in prospective randomized controlled trials involving patients with atopic dermatitis and systemic pharmacotherapy

For individuals with atopic dermatitis (AD), interpreting scientific papers that present clinical outcomes including the Eczema Area and Severity Index (EASI) and Investigators Global Assessment may be difficult. When compared to tabulated data and graphs, images from before and after treatment are often far more meaningful to these patients that ultimately will be candidates for the treatment. This systematic review focused on determining the frequency of clinical image sharing in AD research.

Conducted in accordance with PRISMA guidelines, the review concentrated on randomized controlled trials that investigated predefined and available systemic treatments for AD. The search was performed in the MEDLINE database for studies published from the inception until 21 December 2023.

The review included 60 studies, encompassing 17,799 randomized patients. Across these studies, 16 images representing 6 patients were shared in the manuscripts, leading to a sharing rate of 0.3‰.

The almost missing inclusion of patient images in clinical trial publications hinders patient understanding. Adding images to scientific manuscripts could significantly improve patients' comprehension of potential treatment outcomes. This review highlights the need for authors, the pharmaceutical industry, study sponsors, and publishers to enhance and promote patient information through increased use of visual data.

Drug survival analysis of dupilumab and associated predictors in patients with atopic dermatitis in South Korea: single-center, retrospective study

Dupilumab is a biologic medication that is used for the treatment of moderate-to-severe atopic dermatitis (AD). Long-term data on dupilumab drug survival in Asia patients with AD are limited. A single-center, retrospective study was performed to assess drug survival between March 2019 and March 2023. Drug survival and associated characteristics were analyzed using Kaplan-Meier survival curves and multivariate Cox regression analysis, respectively. A total of 124 patients with AD (Mean age [standard deviation], 26.0 [8.6] years) with a 4 years-overall dupilumab drug survival rate of 87.9%, were included in this study. Characteristics associated with shorter drug survival were the low eczema area and severity index (EASI) scores at baseline (hazard ratio [HR] 0.84; 95% confidence interval [CI] 0.75-0.94, p-value = 0.003) and non-insurance coverage of dupilumab (HR 11.87; 95% CI 3.28-42.99, p-value = 0.001). This retrospective study demonstrated good overall 4-year dupilumab survival (87.6%) in South Korea. Patients with low baseline EASI scores and those who did not have insurance for dupilumab treatment discontinued the therapy frequently. To the best of our knowledge, this is the first long-term dupilumab drug survival study conducted in Asia with predictors.

Real-World Safety Profile of Biologic Drugs for Severe Uncontrolled Asthma: A Descriptive Analysis from the Spanish Pharmacovigilance Database

Background: The present investigation provides a thorough analysis of adverse drug reactions (ADRs) reported in the Database of the Spanish Pharmacovigilance System (FEDRA) for biologic medications primarily indicated for severe refractory asthma, including omalizumab, mepolizumab, reslizumab, benralizumab, dupilumab, and tezepelumab. Our main objective was to identify ADRs not documented in the drugs' Technical Sheets (summary of product characteristics, SmPC), potentially indicating unrecognized risks meriting pharmacovigilance attention. Methods: Data spanning from each drug's market introduction until 22 January 2024, were analyzed, sourced from direct submissions to the Spanish Pharmacovigilance System, industry communications, and literature reviews. We evaluated notifications impartially to ensure a comprehensive review of all the ADRs associated with these medications. Results: This investigation underlines the critical role of post-marketing surveillance in enhancing patient safety. It emphasizes the necessity for healthcare professionals to report ADRs comprehensively to foster a robust pharmacovigilance system. Furthermore, the study highlights gaps between the reported ADRs and the information provided in SmPCs, signaling potential areas for improvement in drug safety monitoring and regulatory oversight. Conclusions: Finally, these findings may contribute to informed decision making in clinical practice and regulatory policy, ultimately advancing patient care and safety in the management of severe uncontrolled asthma.

Cost-Effectiveness of Dupilumab and Oral Janus Kinase Inhibitors for the Treatment of Moderate-to-Severe Atopic Dermatitis in Singapore

BACKGROUND

Atopic dermatitis (AD) affects both adults and children, impacting their quality of life and productivity; however, traditional systemic treatments such as cyclosporine have limitations. Emerging novel systemic interventions, including monoclonal antibodies and Janus kinase (JAK) inhibitors, have been shown to improve patient outcomes.

OBJECTIVE

This study evaluates the cost-effectiveness of novel systemic interventions for moderate-to-severe AD in adults compared with the best supportive care (BSC) in Singapore.

METHODS

The economic evaluation used a hybrid model consisting of a decision tree and Markov model. Treatment responses at 16 weeks were based on a network meta-analysis that was developed specifically for this study. Long-term response, discontinuation rates, episodes of flares and treatment-emergent adverse events were obtained from key dupilumab, abrocitinib, baricitinib and upadacitinib trials. The study had a 5-year time horizon and considered the healthcare payer's perspective. Sensitivity and scenario analyses were performed as well.

RESULTS

Baricitinib 4 mg and 2 mg have the lowest incremental cost-effectiveness ratios, at Singapore dollars (S$) 60,730/quality-adjusted life-year (QALY) and S$66,842/QALY, respectively. Upadacitinib 30 mg offers the highest incremental QALY gain, while baricitinib 2 mg offers the least. The cost of the intervention drugs accounted for the highest proportion of the overall expenses (68-93%) for those in the maintenance state. Other influential factors within the model included (1) the incremental utility derived from intervention response; (2) the probability of achieving Eczema Area and Severity Index 75 (EASI-75) with BSC; and (3) the relative risk of achieving EASI-75 with the interventions. In a scenario where the cost of all drugs is matched to the lowest-priced drug, the top three cost-effectiveness interventions are dupilumab, upadacitinib 30 mg and abrocitinib 200 mg, respectively.

CONCLUSION

The interventions are found to be cost-effective at their existing prices when compared with BSC. Ideally, a composite score of treatment success and quality-of-life scores ought to be included, but such data were unavailable. Future research should consider conditional discontinuation data and long-term outcomes when such data become accessible.

A Comprehensive Review of Biologics in Phase III and IV Clinical Trials for Atopic Dermatitis

Atopic dermatitis (AD) is a skin condition characterized by significant challenges and a substantial deterioration in the life quality for affected patients. The therapeutic landscape for AD has witnessed a transformative shift with the emergence of biologic therapies. Our focus centers on biologics currently undergoing phase III and IV clinical trials, deeming them to hold the highest potential for significant clinical relevance. To identify biologic drugs under development in phase III and IV clinical trials, we searched ClinicalTrials.gov. Additional relevant trials were identified through JapicCTI/ Japan Registry of Clinical Trials (jRCT) with a citation search. A search in MEDLINE and EMBASE was performed. There have been 76 clinical trials identified concerning biologic drugs: dupilumab (34 trials), lebrikizumab (14 trials), tralokinumab (10 trials), rocatinlimab (7 trials), amlitelimab (2 trials), nemolizumab (6 trials), MG-K10 (1 trial), CM310 (1 trial), 611 (1 trial). A search in MEDLINE revealed 132 articles concerning phase III and IV clinical trials for AD treatment. A total of 39 articles concerned biologic drugs covering 23 clinical trials. A search in EMBASE revealed 268 relevant articles, allowing us to identify results of an additional six clinical trials. The safety and efficacy of these biologics are comprehensively addressed in this review. This comprehensive review aims to explore the current landscape of biologic therapies for AD, delving into the latest research findings, clinical trial outcomes, and the diverse mechanisms of action employed by these novel interventions.

Dupilumab Safety and Efficacy up to 1 Year in Children Aged 6 Months to 5 Years with Atopic Dermatitis: Results from a Phase 3 Open-Label Extension Study

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.

Atopic dermatitis: treatment and innovations in immunotherapy

Atopic dermatitis (AD) is a common inflammatory skin disease characterized by itching and skin barrier dysfunction. Moderate to severe AD is often refractory to first-line topical treatments, and systemic immunosuppressants have been shown to be effective but have significant adverse effects. The paucity of basic treatments has contributed to the development of targeted topical and systemic immunotherapies based on the use of small molecules and biologic drugs which can directly interact with AD pathogenetic pathways. They represent a new era of therapeutic innovation. Additional new treatments are desirable since AD is a heterogeneous disease marked by different immunological phenotypes. This manuscript will review the mechanism of action, safety profile, and efficacy of promising new systemic immunological treatments for AD. Since moderate to severe AD can result in poor quality of life, the development of targeted and well-tolerated immunomodulators is a crucial purpose. The introduction of new pharmacological agents may offer new therapeutic options. However, there is the need to evaluate how "narrow-acting" agents, such as individual interleukin inhibitors, will perform under the safety and efficacy profiles compared with "broad-acting" agents, such as JAK inhibitors.

Interleukin antagonists for atopic dermatitis: a new era of therapy

INTRODUCTION

Over the last decade, increasing understanding of the immunopathogenesis of atopic dermatitis (AD) enabled the recognition of multiple therapeutic targets and subsequently the development of novel, highly effective systemic treatments, including interleukin (IL)-antagonists. To date, the IL-4Ra-inhibitor dupilumab and the IL-13 inhibitor tralokinumab have gained regulatory approval in Europe for the treatment of moderate-to-severe AD, while more than 70 new therapeutics are currently in development.

AREAS COVERED

In this review, we address the role of ILs in the pathogenesis of AD and provide an overview of the novel and investigational IL-antagonists, as regards their efficacy and safety on moderate-to-severe AD.

EXPERT OPINION

Current data have established IL-4 and IL-13 inhibitors as effective and safe for the treatment of moderate-to-severe AD, as regards the rapid control of flares as well as the long-term remission of the disease. Data regarding the efficacy and safety of other IL-inhibitors, including those targeting IL-31, IL-22, IL-33, IL-36 and IL-18, are accumulating. There is still an unmet need for real-world-evidence studies and head-to-head studies for both currently available and future agents in AD treatment. Establishing predictive biomarkers of treatment response in a disorder of such considerable heterogenicity might help physicians pursue a patient-tailored therapeutic response.

Dupilumab induced ocular surface disease: A prospective case series

PURPOSE

To identify the incidence, risk factors, demographics, and clinical profile of dupilumab-induced ocular surface disease (DIOSD) in patients with atopic dermatitis (AD), propose a standardised treatment protocol (STP) and evaluate the response.

METHODS

Prospective case series of AD patients treated in the Dermatology Department, Royal Victoria Infirmary, Newcastle upon Tyne, UK developing ocular symptoms after commencing Dupilumab between September 2018 and February 2020. A standard history and examination protocol were used including subjective symptom severity grading and Ocular Surface Disease Index (OSDI) questionnaire on each visit. Standard treatment was prescribed, and response evaluated.

RESULTS

32 of 113 included patients (28.31%) developed DIOSD, of which 20 (62.5%) were referred to the Cornea Service. Median age was 38.0 years (IQR 26.8; range 19-74). Male to female ratio was 1:1. Average time to onset of ocular symptoms from starting dupilumab was 9.2 weeks (IQR 8.8; range 0.1-40). 90% patients had bilateral conjunctival inflammation and blepharitis at presentation. Significant improvement in the subjective severity scale and the median OSDI score (from 34.0 to 10.2) was noted in response to topical eye treatment. Dupilumab was discontinued in none.

CONCLUSIONS

DIOSD is not uncommon although, with timely referral and appropriate topical treatment better clinical outcome and patient satisfaction can be achieved without the need to discontinue Dupilumab. Prior allergic conjunctivitis did not affect the incidence or severity of DIOSD. Further prospective studies with longer follow-up and more focus on possible disease mechanism such as goblet cell related changes and immune response are needed.

Considerations for managing elderly patients with atopic dermatitis

INTRODUCTION

Atopic dermatitis (AD) diagnosis in elderly is challenging, due to its clinical polymorphism and the lack of diagnostic biomarkers. Moreover, the chronicity of the disease and the complex pathogenetic mechanism, make elderly AD management challenging.

AREAS COVERED

A narrative review of the current literature was performed using the PubMed, Medline, Embase, and Cochrane Skin databases, by researching the following terms: 'atopic dermatitis,' 'clinical phenotypes,' 'eczema,' 'elderly patients,' 'elderly type atopic dermatitis,' 'eczema clinical presentation.' The aim was to report the current knowledge on pathogenesis, clinical presentation, and treatment options of elderly AD.

EXPERT OPINION

Elderly type AD has recently been identified as a separate entity, with an increasing prevalence. With aging, both immunosenescence and barrier alterations can cause or modify AD presentation. Moreover, a chronic proinflammatory state (so-called 'inflammaging') is often present in elderly subjects. Older patients with AD may present with peculiar immunophenotypic profile, making AD diagnosis challenging. Similarly, the chronicity of the disease and the complex pathogenetic mechanism, make AD management a challenge. Indeed, systemic therapies for AD are often contraindicated or not tolerated and the management of elderly type AD is often burdened with numerous difficulties, leading to undertreated disease. Even if dupilumab and tralokinumab represent a valuable therapeutic weapon, more data on safety of JAK inhibitors are required.

Interventions for anxiety and depression in patients with atopic dermatitis: a systematic review and meta-analysis

Atopic dermatitis (AD) is a chronic inflammatory skin disease that is associated with anxiety and depression. Few studies have addressed interventions for symptoms of anxiety and depression in this population. To determine the efficacy of interventions for anxiety and depression in patients with AD. PubMed, MEDLINE, EMBASE, and PsycINFO were searched from inception to November 2023. English-language studies published in peer-reviewed journals evaluating the effect of interventions on anxiety and/or depression using validated assessment tools on patients with AD were included. Titles, abstracts, and articles were screened by at least two independent reviewers. Of 1410 references that resulted in the initial search, 17 studies were included. Fourteen of these studies are randomized controlled trials, while the other 3 studies are prospective controlled trials with pre and post-test designs. Data were extracted using a standardized extraction form, and the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines were followed. To accommodate trials with multiple interventions (each compared to a control group), we conducted a mixed-effects meta-analysis with the trial as a random effect. Prespecified outcomes were changes in symptoms of anxiety and depression in patients with AD as evaluated using standardized assessment tools. Of the 17 studies included in this systematic review, 7 pharmacological intervention studies with 4723 participants examining 5 different medications were included in a meta-analysis. Of these studies, only 1 study evaluated medications prescribed to treat anxiety and/or depression; the rest evaluated medications prescribed to treat AD. Meta-analysis of all the pharmacological interventions resulted in significant improvement in anxiety, depression, and combined anxiety-depression scale scores (standardized mean difference [95% CI]: - 0.29 [- 0.49 to - 0.09], - 0.27 [- 0.45 to - 0.08], - 0.27 [- 0.45 to - 0.08]) respectively. The 10 non-pharmacological studies with 2058 participants showed general improvement in anxiety but not depression. A meta-analysis of the non-pharmacological interventions was not conducted due to variable approaches and limited data. Pharmacological interventions designed to improve AD were found to improve anxiety and depression in patients with moderate-severe disease. More comprehensive studies on non-pharmacological and pharmacological interventions that primarily target anxiety and depression are needed.

Ocular surface disease in moderate-to-severe atopic dermatitis patients and the effect of biological therapy

Atopic dermatitis (AD) is a chronic inflammatory skin disease for which new targeted therapies are currently available. Due to the increased rates of ocular surface disease (OSD) reported during treatment with these new targeted treatments, more insight into the occurrence and pathomechanism of OSD in moderate-to-severe AD patients is needed. Therefore, this review's first part highlights that most patients with moderate-to-severe AD already have characteristics of OSD before starting targeted treatment. Remarkably, not all AD patients with OSD report ocular symptoms. OSD in AD is associated with less conjunctival goblet cells (GC) compared to healthy controls. In addition, OSD severity in AD patients is associated with high AD activity, the presence of eyelid and/or facial eczema, and high levels of AD-related severity biomarkers in tear fluid. The second part of this review highlights that pre-existing ocular pathology (e.g. in combination with the use of ophthalmic medication or eyelid eczema) may be associated with the development of dupilumab-associated ocular surface disease (DAOSD). During dupilumab treatment, DAOSD (which can be new-onset OSD or worsening of pre-existing OSD) is observed in approximately one-third of the dupilumab-treated AD patients. Anti-inflammatory ophthalmic treatment improves DAOSD, and dose reduction of dupilumab may also be an effective treatment option. The pathomechanism of DAOSD is still not fully elucidated. In a prospective study low, but stable conjunctival GC numbers were observed in moderate-to-severe AD patients, before and during dupilumab treatment. However, the Mucin 5 AC (MUC5AC) expression of GCs decreased during dupilumab treatment, suggesting an impairment of the GC function by dupilumab treatment. In addition, higher dupilumab tear fluid levels were found in dupilumab-treated AD patients with moderate-to-severe OSD compared to patients with no or mild OSD, whereas the dupilumab serum levels are similar. Clinicians should be aware of the frequent occurrence of OSD in moderate-to-severe AD patients, and a low-threshold referral to an ophthalmologist is recommended.

Treatable Traits in Asthma: The Importance of Extrapulmonary Traits-GERD, CRSwNP, Atopic Dermatitis, and Depression/Anxiety

Treatable traits is a personalized medicine approach to the management of airway disease. Assessing traits within the 3 domains of pulmonary, extrapulmonary, and behavioral/lifestyle/risk factor traits, and applying targeted treatments to effectively manage these traits, enables a holistic and personalized approach to care. Asthma is a heterogeneous and complex airway disease that is frequently complicated by several extrapulmonary traits that impact asthma outcomes and predict future outcomes. We propose that the identification of extrapulmonary and behavioral risk factor traits and the implementation of targeted therapy will lead to improved management of people with asthma. Furthermore, many extrapulmonary traits present as "connected comorbidities"; that is, they coexist with asthma, have an impact on asthma, and effective treatment improves both asthma and the comorbidity or the comorbidities may share a similar mechanism. In this review, we explore this concept and look at atopic dermatitis, chronic rhinosinusitis with nasal polyps, gastroesophageal reflux disease, anxiety, and depression as treatable traits of asthma and how these can be managed using this approach.

Targeted Systemic Therapies for Adults with Atopic Dermatitis: Selecting from Biologics and JAK Inhibitors

Therapeutic options for people with moderate or severe atopic dermatitis refractory to topical therapy have rapidly expanded in recent years. These new targeted immunomodulatory agents-biologics and Janus kinase (JAK) inhibitors-have each demonstrated high levels of efficacy and acceptable safety in mostly placebo-controlled clinical trials for atopic dermatitis, but there is no universally applicable algorithm to help choose between them for a given patient. Hence, patients and physicians should utilize shared decision making, discussing efficacy, safety, mode of delivery, monitoring, costs, speed of onset, and other factors to reach individualized treatment decisions. In this review, we try to aid shared decision making by summarizing the efficacy, safety, and monitoring of biologics and oral JAK inhibitors for adults with atopic dermatitis. Network meta-analyses suggest that higher doses of abrocitinib and upadacitinib are more effective than biologics. They also show that, among biologics, dupilumab is likely more effective than tralokinumab and lebrikizumab. Biologics are generally considered safer than JAK inhibitors, although concerns about JAK inhibitors are mainly extrapolated from older generation JAK inhibitors used in higher-risk populations. We also outline evidence and considerations for choosing and using systemic immunomodulatory treatments for special populations including pregnant individuals, those with human immunodeficiency virus (HIV), hepatitis B and C, end stage kidney disease, and older adults.

A Bispecific, Tetravalent Antibody Targeting Inflammatory and Pruritogenic Pathways in Atopic Dermatitis

Inhibition of IL-4/IL-13 signaling has dramatically improved the treatment of atopic dermatitis (AD). However, in many patients, clinical responses are slow to develop and remain modest. Indeed, some symptoms of AD are dependent on IL-31, which is only partially reduced by IL-4/IL-13 inhibition. Thus, there is an unmet need for AD treatments that concomitantly block IL-4/IL-13 and IL-31 pathways. We engineered NM26-2198, a bispecific tetravalent antibody designed to accomplish this task. In reporter cell lines, NM26-2198 concomitantly inhibited IL-4/IL-13 and IL-31 signaling with a potency comparable with that of the combination of an anti-IL-4Rα antibody (dupilumab) and an anti-IL-31 antibody (BMS-981164). In human PBMCs, NM26-2198 inhibited IL-4-induced upregulation of CD23, demonstrating functional binding to FcγRII (CD32). NM26-2198 also inhibited the secretion of the AD biomarker thymus and activation-regulated chemokine (TARC) in blood samples from healthy human donors. In male cynomolgus monkeys, NM26-2198 exhibited favorable pharmacokinetics and significantly inhibited IL-31-induced scratching at a dose of 30 mg/kg. In a repeat-dose, good laboratory practice toxicology study in cynomolgus monkeys, no adverse effects of NM26-2198 were observed at a weekly dose of 125 mg/kg. Together, these results justify the clinical investigation of NM26-2198 as a treatment for moderate-to-severe AD.

Unraveling Atopic Dermatitis: Insights into Pathophysiology, Therapeutic Advances, and Future Perspectives

Atopic dermatitis (AD) is an inflammatory skin condition that frequently develops before the onset of allergic rhinitis or asthma. More than 10% of children are affected by this serious skin condition, which is painful for the sufferers. Recent research has connected the environment, genetics, the skin barrier, drugs, psychological factors, and the immune system to the onset and severity of AD. The causes and consequences of AD and its cellular and molecular origins are reviewed in this paper. The exploration of interleukins and their influence on the immunological pathway in AD has been facilitated by using relevant biomarkers in clinical trials. This approach enables the identification of novel therapeutic modalities, fostering the potential for targeted translational research within the realm of personalized medicine. This review focuses on AD's pathophysiology and the ever-changing therapeutic landscape. Beyond the plethora of biologic medications in various stages of approval or development, a range of non-biologic targeted therapies, specifically small molecules, have emerged. These include Janus kinase (JAK) inhibitors like Baricitinib, Upadacitinib, and Abrocitinib, thus expanding the spectrum of therapeutic options. This review also addresses the latest clinical efficacy data and elucidates the scientific rationale behind each targeted treatment for atopic dermatitis.

Clinically Meaningful Responses to Dupilumab Among Children Aged 6 Months to 5 Years with Moderate-to-severe Atopic Dermatitis who did Not Achieve Clear or Almost Clear Skin According to the Investigator's Global Assessment: A Post Hoc Analysis of a Phase 3 Trial

In young children, atopic dermatitis (AD) imposes a multidimensional burden on many aspects of their quality of life (QoL) and that of their families. LIBERTY AD PRESCHOOL part B was a randomized, double- blinded, placebo-controlled phase 3 trial in 162 children (aged 6 months to 5 years) with moderate-to- severe AD receiving dupilumab or placebo, plus low-potency topical corticosteroids. Post hoc analyses were performed on the full analysis set (FAS) and a subset of patients with Investigator's Global Assessment score > 1 at week 16. The primary outcome was the proportion of patients at week 16 achieving a composite endpoint encompassing clinically meaningful changes in AD signs, symptoms and QoL: ≥ 50% improvement in Eczema Area and Severity Index; and/or ≥ 4-point reduction in worst scratch/itch numerical rating scale; and/or ≥ 6-point reduction in Children's Dermatology Life Quality Index/Infants' Dermatitis Quality of Life Index. Significantly more patients receiving dupilumab vs placebo achieved the composite endpoint in both the FAS (77.7% vs 24.6%, p < 0.0001) and subgroup (68.9% vs 21.5%, p < 0.0001). Dupilumab provided rapid and significant, clinically meaningful improvements in AD signs, symptoms, and QoL in the overall group and subgroup of patients who did not achieve clear or almost clear skin at week 16.

Dupilumab Treatment in Pediatric Patients Aged 6-11 Years with Severe Atopic Dermatitis Whose Disease Is Not Adequately Controlled: A Review

Atopic dermatitis (AD) is the most common inflammatory skin disease in children. Children with severe AD have a multidimensional disease burden characterized by skin lesions, itching, frequent infections, sleep deprivation, and a high rate of comorbidities. These impact the mental health and overall quality of life of not only the children but also of their parents and caregivers. There are few effective available treatment options for young children with severe AD that are suitable for long-term use. Due to their adverse effects, practice guidelines consider systemic agents inappropriate for this age group, although they are still used off-label in extreme cases. The biologic dupilumab has recently been approved for children aged 6-11 years with severe (EU) and moderate-to-severe (USA) AD, offering hope to this population of patients with a high unmet clinical need. The purpose of this review is to describe the unmet needs of AD patients aged 6-11 years prior to dupilumab approval and to summarize existing clinical data supporting dupilumab's safety and efficacy in these children.

Efficacy and Safety of Dupilumab for the Treatment of Severe Atopic Dermatitis in Clinical Practice: A Single Center Experience

BACKGROUND

Dupilumab is a new targeted therapy for severe atopic dermatitis (AD) with limited real-world evidence.

OBJECTIVE

Explore our experience with dupilumab for AD in clinical practice at a tertiary care center.

MATERIAL AND METHOD

Unicentric observational retrospective study including adult and pediatric patients with severe AD receiving dupilumab between December 2017 and December 2021. The Eczema Area and Severity Index (EASI) score, Pruritus Numerical Rating Scale (P-NRS) and Sleep disturbance Numerical Rating Scale (S-NRS) were recovered to assess severity and response.

RESULTS

Fifty-nine patients received dupilumab: 52, 48, 26 and 13 patients reached 6, 12, 24 and 36 months of treatment, respectively. The EASI-75 response rates were 94.2%, 95.8%, 92.3% and 100% at months 6, 12, 24 and 36. The EASI-90 response rates were 63.5%, 72.9%, 84.6% and 92.3% at months 6, 12, 24 and 36. The EASI <7 response rates were 92.3%, 91.7%, 88.5% and 100% at months 6, 12, 24 and 36. The P-NRS ≥4 reduction rates were 86%, 87.5%, 92.3% and 100% at months 6, 12, 24 and 36. The S-NRS ≥4 reduction rates were 82.7%, 85.4%, 100% and 100% at months 6, 12, 24 and 36. Adverse events were mild and occurred in 20.3% of patients, all of them adults.

CONCLUSION

Our findings support dupilumab's favorable efficacy and tolerability profile in clinical practice. Dupilumab offers a rapid and sustained response, regardless of combined therapy. Longer follow-ups are still required to adequately assess its performance.

Impact of 1-year treatment with dupilumab on work productivity in Japanese patients with atopic dermatitis

Atopic dermatitis (AD) places a burden on work productivity. Recently, dupilumab was approved for AD, but its impact on work productivity in Japanese patients has not been reported. Furthermore, data on the effect of long-term treatment with dupilumab on work productivity are limited. We investigated the work productivity and activity in Japanese patients with moderate-to-severe AD, utilizing the Japanese version of the Work Productivity and Activity Impairment (WPAI-AD-Japan) questionnaire. Furthermore, we examined the impact of dupilumab on work productivity. Adult moderate-to-severe AD patients treated with dupilumab for more than 12 months from March 2020 to June 2022 who filled out the WPAI-AD-Japan questionnaire were included. Twenty-eight adult AD patients were analysed. Absenteeism was low (mean: 5.3%), but presenteeism, work productivity loss and activity impairment were high (36.8%, 39.7%, 48.9%, respectively). Significant positive correlations were observed between work productivity loss and visual analogue scale (VAS) score of pruritus and between activity impairment and dermatology life quality index (DLQI). Dupilumab treatment significantly reduced presenteeism, work productivity loss and activity impairment at both 6 and 12 months. The extent of their amelioration was numerically higher at 12 months than at 6 months. The reduction rates in presenteeism, work productivity loss and activity impairment were positively correlated with the reduction rates in DLQI and VAS score of pruritus at 12 months. Dupilumab improved work productivity in Japanese AD patients. Long-term remission of pruritus and improved quality of life are important for comprehensive improvement of work productivity.

Guidelines of care for the management of atopic dermatitis in adults with phototherapy and systemic therapies

BACKGROUND

For people with atopic dermatitis (AD) refractory to topical therapies, treatment with phototherapy and systemic therapies can be considered. Multiple biologic therapies and Janus kinase (JAK)inhibitors have been approved since 2014 to treat AD. These guidelines update the 2014 recommendations for management of AD with phototherapy and systemic therapies.

OBJECTIVE

To provide evidence-based recommendations on the use of phototherapy and systemic therapies for AD in adults.

METHODS

A multidisciplinary workgroup conducted a systematic review and applied the GRADE approach for assessing the certainty of evidence and formulating and grading recommendations.

RESULTS

The workgroup developed 11 recommendations on the management of AD in adults with phototherapy and systemic agents, including biologics, oral JAK inhibitors, and other immunomodulatory medications.

LIMITATIONS

Most randomized controlled trials of phototherapy and systemic therapies for AD are of short duration with subsequent extension studies, limiting comparative long-term efficacy and safety conclusions.

CONCLUSIONS

We make strong recommendations for the use of dupilumab, tralokinumab, abrocitinib, baricitinib, and upadacitinib. We make conditional recommendations in favor of using phototherapy, azathioprine, cyclosporine, methotrexate, and mycophenolate, and against the use of systemic corticosteroids.

Safety and efficacy of dupilumab in adult atopic dermatitis in Singapore

INTRODUCTION

Dupilumab, a biologic approved for treatment of moderate-to-severe atopic dermatitis (AD), has been reported to be largely effective with minimal adverse effects. However, being a targeted therapy, its effectiveness and side effects are expected to be varied in a heterogeneous ethnic population. Currently, the majority of studies on dupilumab are based on Western populations.

METHODS

A retrospective cohort of 51 patients with moderate-to-severe AD treated with dupilumab at a tertiary skin institute from January 2018 to February 2020 was included. Outcome measures such as Scoring Atopic Dermatitis (SCORAD), Eczema Area and Severity Index (EASI) and Dermatology Quality of Life Index (DLQI) were analysed at baseline and after 16 weeks of treatment. Laboratory tests at the respective time points were also measured.

RESULTS

Patients treated with dupilumab showed consistent reduction in body surface area (BSA) involved, SCORAD, EASI and DLQI scores. Concurrently, serum immunoglobulin E (IgE) and absolute eosinophil count showed a downward trend at 4 months of treatment. There was a transient increase in mean serum IgE at 1 month of dupilumab treatment. Also, 42.0% and 35.3% of patients developed eye symptoms, and head and neck dermatitis, respectively, but there were no major adverse events reported. Childhood-onset AD was more likely to have improved BSA scores compared to adult-onset AD.

CONCLUSIONS

Our study confirms the efficacy of dupilumab with real-world data in an adult Asian population. Higher proportions of eye symptoms, and head and neck dermatitis were observed in our cohort compared to other Asian clinical cohort studies. Further studies are needed to evaluate these differences.

Persistent Neutrophil Infiltration and Unique Ocular Surface Microbiome Typify Dupilumab-Associated Conjunctivitis in Patients with Atopic Dermatitis

Objective

To elucidate the pathogenesis of dupilumab (Dupixent®)-associated ocular surface disease (DAOSD).

Design

Prospective single-center cohort study.

Subjects

Twenty patients with moderate-to-severe atopic dermatitis (AD) who received dupilumab and 10 age- and sex-matched healthy controls were enrolled in the study.

Methods

The study cohort underwent a thorough slit-lamp and entire-body dermatologic examination. Conjunctival swabs and smears were collected at baseline, 4 and 16 weeks after treatment initiation, and during the conjunctivitis episode. To analyse the ocular surface microbiome, 16S ribosomal RNA sequencing was performed, smears were hematoxylin and eosin stained, and serum cytokines were measured by using a multiplex immunobead assay.

Main Outcome Measures

Composition of ocular surface microbiome and cellular component as well as serum cytokine levels.

Results

Six of the 20 patients with AD developed DAOSD after dupilumab initiation; these patients responded after a delay to treatment as quantified by Eczema Area and Severity Index and Investigator's Global Assessment score. Conjunctival smears showed massive neutrophilic infiltration and serum analysis revealed increased systemic levels of neutrophil-priming proinflammatory cytokines, in particular interleukin-1β and tumor necrosis factor α, in patients with DAOSD compared with those without it. The ocular surface microbiome of patients with DAOSD was characterized by a diverse and persistent microbial colonization, particularly by Acetobacter aceti. In contrast, microbial diversity decreased in patients with AD without DAOSD after the initiation of dupilumab treatment, especially the abundance of Staphylococcus aureus. In vitro experiments substantiated the potential role of the microbiome, showing increased growth of A. aceti and decreased growth of S. aureus in presence of dupilumab.

Conclusions

Persistent neutrophilic infiltration and a unique microbial landscape on the ocular surface associated with elevated levels of systemic proinflammatory cytokines typify DAOSD.

Real-World Effectiveness of Dupilumab in Adult and Adolescent Patients with Atopic Dermatitis: 2-Year Interim Data from the PROSE Registry

INTRODUCTION

There is a scarcity of data beyond 1 year for the use of dupilumab to treat atopic dermatitis (AD) in a real-world setting. This study aimed to evaluate the 2-year effectiveness of dupilumab among adult and pediatric patients with moderate-to-severe AD included in a real-world, longitudinal database study.

METHODS

PROSE is an ongoing, prospective, observational, multi-center registry in the USA and Canada, designed to collect real-world data from patients aged ≥ 12 years with moderate-to-severe AD who initiate dupilumab in accordance with country-specific prescribing information. Assessments include body surface area affected by AD (BSA), Eczema Area and Severity Index (EASI), Dermatology Life Quality Index (DLQI), Pruritus Numerical Rating Scale (P-NRS), Patient-Oriented Eczema Measure (POEM), Patient Global Assessment of Disease (PGAD) questionnaire score, and occurrence of adverse events (AEs).

RESULTS

Of 764 patients who enrolled in PROSE, 632 (83%) remained in the study at the time of this interim analysis. Improvements were observed at the first post-baseline clinic visit (approximately 3 months) in the clinician-assessed measures (mean BSA and EASI scores); improvements were sustained throughout the 2-year period covered in the present study. Consistent and sustained improvements were also observed over the 2-year period in the patient-reported measures of P-NRS, POEM, and DLQI, and in the proportion of patients reporting "very good/excellent" in answer to the question in the PGAD questionnaire: "Considering all the ways in which your eczema affects you, indicate how well you are doing". Dupilumab treatment was well tolerated, with safety findings consistent with those previously reported in studies of dupilumab for the treatment of AD.

CONCLUSIONS

In the real-world PROSE registry, patients with moderate-to-severe AD experienced sustained improvement in disease control, symptoms, and quality of life up to 2 years after initiating dupilumab treatment. Safety data were consistent with the known safety profile of dupilumab.

GB12-09, a bispecific antibody targeting IL4Rα and IL31Rα for atopic dermatitis therapy

Atopic dermatitis (AD) is a chronic inflammatory skin condition characterized by dysregulated immune responses. The key mediators of AD pathogenesis are T helper 2 (TH2) cells and TH2 cytokines. Targeting interleukin 4 (IL4), IL13 or IL31 has become a pivotal focus in both research and clinical treatments for AD. However, the need remains pressing for the development of a more effective and safer therapy, as the current approaches often yield low response rates and adverse effects. In response to this challenge, we have engineered a immunoglobulin G-single-chain fragment variable (scFv) format bispecific antibody (Ab) designed to concurrently target IL4R and IL31R. Our innovative design involved sequence optimization of VL-VH and the introduction of disulfide bond (VH44-VL100) within the IL31Rα Ab scFv region to stabilize the scFv structure. Our bispecific Ab efficiently inhibited the IL4/IL13/IL31 signaling pathways in vitro and reduced serum immunoglobulin E and IL31 levels in vivo. Consequently, this intervention led to improved inflammation profiles and notable amelioration of AD symptoms. This research highlighted a novel approach to AD therapy by employing bispecific Ab targeting IL4Rα and IL31Rα with potent efficacy.

Mental health interventions for atopic dermatitis: knowledge gaps, pilot programmes and future directions

Atopic dermatitis (AD) is associated with high levels of psychosocial burden, often resulting in poor mental health outcomes. Despite this association, few studies have evaluated the efficacy of mental health interventions within this population. Utilization of multidisciplinary and peer-led support, in addition to equipping patients with psychological tools, may be beneficial in improving mental health outcomes. Future research is needed to determine which interventions and formats are desired by, effective in and accessible to patients and caregivers with AD.

Canalicular obstruction associated with dupilumab

PURPOSE

Dupilumab is a novel treatment for severe atopic dermatitis and is associated with a range of ocular complications such as blepharoconjunctivitis, keratitis, cicatricial ectropion and punctal stenosis.

METHODS

We report 4 patients with canalicular obstruction in association with dupilumab therapy, and we describe their treatment and outcomes in each case.

RESULTS

Canalicular obstruction was diagnosed by an oculoplastic consultant between 3 years and 3 months and 4 years and 9 months after the commencement of dupilumab therapy. Case 1 underwent nasolacrimal intubation, case 2 was treated conservatively, and case 4 underwent endonasal dacryocystorhinostomy and these patients' symptoms resolved. Unfortunately, in case 3 despite endonasal dacryocystorhinostomy with stenting they remained symptomatic.

CONCLUSION

This case series adds to the growing number of ocular complications associated with dupilumab therapy, and there is yet an optimal treatment strategy to mitigate these complications. It is possible that simple conservative measures such as discontinuation of dupilumab and topical treatments with steroids can eventually lead to some form of recovery and recanalisation of the canalicular system. Early referral to an ophthalmologist prior to the development of canalicular obstruction to control the inflammatory ocular surface could reduce the risks of cicatricial sequelae from dupilumab, and temporary stenting of the canalicular system could be attempted as a method to keep the canalicular system patent, whilst the patient remained on treatment.

Systemic treatments for atopic dermatitis (eczema): Systematic review and network meta-analysis of randomized trials

BACKGROUND

Atopic dermatitis (AD) is an inflammatory skin condition with multiple systemic treatments and uncertainty regarding their comparative impact on AD outcomes.

OBJECTIVE

We sought to systematically synthesize the benefits and harms of AD systemic treatments.

METHODS

For the 2023 American Academy of Allergy, Asthma & Immunology and American College of Allergy, Asthma, and Immunology Joint Task Force on Practice Parameters AD guidelines, we searched MEDLINE, EMBASE, CENTRAL, Web of Science, and GREAT databases from inception to November 29, 2022, for randomized trials addressing systemic treatments and phototherapy for AD. Paired reviewers independently screened records, extracted data, and assessed risk of bias. Random-effects network meta-analyses addressed AD severity, itch, sleep, AD-related quality of life, flares, and harms. The Grading of Recommendations Assessment, Development and Evaluation approach informed certainty of evidence ratings. This review is registered in the Open Science Framework (https://osf.io/e5sna).

RESULTS

The 149 included trials (28,686 patients with moderate-to-severe AD) evaluated 75 interventions. With high-certainty evidence, high-dose upadacitinib was among the most effective for 5 of 6 patient-important outcomes; high-dose abrocitinib and low-dose upadacitinib were among the most effective for 2 outcomes. These Janus kinase inhibitors were among the most harmful in increasing adverse events. With high-certainty evidence, dupilumab, lebrikizumab, and tralokinumab were of intermediate effectiveness and among the safest, modestly increasing conjunctivitis. Low-dose baricitinib was among the least effective. Efficacy and safety of azathioprine, oral corticosteroids, cyclosporine, methotrexate, mycophenolate, phototherapy, and many novel agents are less certain.

CONCLUSIONS

Among individuals with moderate-to-severe AD, high-certainty evidence demonstrates that high-dose upadacitinib is among the most effective in addressing multiple patient-important outcomes, but also is among the most harmful. High-dose abrocitinib and low-dose upadacitinib are effective, but also among the most harmful. Dupilumab, lebrikizumab, and tralokinumab are of intermediate effectiveness and have favorable safety.

Baseline Demographics, Comorbidities, Treatment Patterns and Burden of Atopic Dermatitis in Adults and Adolescents from the GLOBOSTAD Long-Term Observational Study

INTRODUCTION

Insights into real-world treatment of atopic dermatitis (AD) are relevant to clinical decision making. The aim of this analysis was to characterize patients who receive dupilumab for AD in a real-world setting.

METHODS

The GLOBOSTAD registry is an ongoing, longitudinal, prospective, observational study of patients with AD who receive dupilumab according to country-specific prescribing information. We report baseline characteristics, comorbidities and treatment patterns for patients enrolled from July 11, 2019 to March 31, 2022. Analyses are descriptive; no formal statistical comparisons were performed.

RESULTS

Nine hundred fifty-two adults and adolescents were enrolled in GLOBOSTAD. Patients had a high disease burden before starting dupilumab: (mean [standard deviation]) percent body surface area affected (44.8 [24.42]), Eczema Area and Severity Index total score (24.8 [12.95]), SCORing Atopic Dermatitis total score (60.5 [16.34]), Patient-Oriented Eczema Measure total score (19.7 [6.37]) and Dermatology Life Quality Index total score (13.7 [7.02]). Overall, 741 (77.8%) patients reported ≥ 1 type 2 inflammatory comorbidities, most frequently allergic rhinitis (492 [51.7%]), asthma (323 [33.9%]), food allergy (294 [30.9%]) or another allergy (274 [28.8%]). In the previous 12 months, 310 (32.6%) patients had received systemic non-steroidal immunosuppressants and 169 (17.8%) systemic corticosteroids; 449 (47.2%) had received topical corticosteroids, most commonly potent topical corticosteroids; 141 (14.8%) had received topical calcineurin inhibitors and 32 (3.4%) ultraviolet therapy. Most (713 [74.9%]) patients started dupilumab because of prior treatment failure.

CONCLUSION

Patients enrolled in GLOBOSTAD demonstrated considerable multidimensional burden of disease across AD signs, symptoms and quality of life despite previous use of systemic and non-systemic AD treatments.

A Mini Review of the Impact of Baseline Disease Severity on Clinical Outcomes: Should We Compare Atopic Dermatitis Clinical Trials?

Based on clinical trials of systemic treatments in adults with moderate-to-severe atopic dermatitis (AD) reported between 2014 and 2023, we used linear regression to investigate relationships between baseline Eczema Area and Severity Index (EASI) scores and (1) study start date, (2) EASI response, and (3) rescue medication rates. Analysis 1 was conducted with all patients from monotherapy and combination therapy trials; analyses 2 and 3 used monotherapy trial placebo arms. Across 32 trials with a baseline inclusion criterion of EASI ≥ 16, baseline mean EASI scores decreased with study start date. The lowest and highest baseline mean EASI scores were 25.1 and 33.6 (median 21.1 and 30.5), reported for the WW001 Phase 2 trial of rademikibart (formerly CBP-201; start date, July 2020) and the SOLO1 Phase 3 trial of dupilumab (start date, December 2014), respectively. In placebo arms, lower baseline EASI scores tended to be associated with greater percent reductions in EASI scores at Week 16 and less rescue medication usage. The WW001 trial placebo arm had the lowest baseline EASI score (mean 25.2; median 22.1), lowest rescue medication rate (14.3%), and a large reduction in least squares mean EASI scores (- 39.7%) at Week 16. In summary, baseline mean EASI scores have decreased across clinical trials conducted during the last decade. Less severe AD at baseline tended to be associated with greater placebo response and less use of rescue medications in placebo arms. Intertrial differences in variables, such as baseline AD severity, limit the validity of indirectly comparing clinical trials.

Dupilumab Treatment Efficacy and Impact on Clinical Scores, Serum Biomarkers, and Itch in Adult Patients with Atopic Dermatitis: A Retrospective Analysis

Purpose

Dupilumab, a fully human monoclonal antibody that inhibits the signaling pathways of interleukin (IL)-4 and IL-13, has demonstrated remarkable efficacy in the treatment of atopic dermatitis (AD). Dupilumab has been reported to attenuate itch and reduce several serum markers, including blood lactate dehydrogenase (LDH), blood eosinophil count, and serum total immunoglobulin E (IgE).

Patients and Methods

The present study investigated retrospectively changes in clinical scores and serum biomarker from 175 adults with moderate-to-severe AD treated with dupilumab. Clinical manifestations were assessed using eczema area and severity index (EASI) and visual analogue scale (VAS) for itch at baseline and subsequently at 16-week intervals up to a duration of 48 weeks. Total IgE, LDH and blood eosinophil count were also collected.

Results

The dupilumab treatment significantly improved EASI and VAS scores and decreased serum levels of IgE, LDH, and total eosinophil count. The EASI scores were positively correlated with VAS for itch at all recorded time points, whereas serum biomarkers did not exhibit a strong correlation with EASI scores.

Conclusion

These findings highlight the close relationship between the extent and severity of eczema and the intensity of itch experienced by patients and suggest that factors beyond the measured serum biomarkers play a significant role in the clinical manifestations of AD, emphasizing the complex nature of the disease.

Short-term efficacy and safety of biologics and Janus kinase inhibitors for patients with atopic dermatitis: A systematic review and meta-analysis

Background

In recent years, biologics targeting key cytokines and Janus kinase (JAK) inhibitors have demonstrated favorable efficacy and safety outcomes for atopic dermatitis (AD) therapy. To evaluate the short-term efficacy and safety of AD therapy involving biologics, JAK inhibitors, and their combination with topical corticosteroids (TCS) for patients with AD, we conducted this systematic review and meta-analysis. Using eligible randomized clinical trials (RCTs) of 12 or 16 weeks of treatment with systemic medications and 4 weeks of topical treatment for AD.

Methods

PubMed, Web of Science, ScienceDirect, and the Cochrane Library were searched from inception up to October 25, 2023. English-language randomized clinical trials (RCTs) of 12 or 16 weeks of treatment with systemic medications and 4 weeks of topical treatment for AD were included. Titles, abstracts, and articles were screened in duplicate. Of 7261 citations, 37 studies were included. The data were analyzed using Review Manager 5.4 and the outcomes were measured by the Eczema Area and Severity Index (EASI), Investigator Global Assessment (IGA), the pruritus Numerical Rating Scale (NRS), as well as instances of adverse events (AE), and serious AE (SAE), which were presented as risk ratio (RR) with a 95 % confidence interval (CI). The efficacy of the biological therapies was analyzed with the percentage of patients who have achieved EASI 75, EASI 90, IGA 0/1 and pruritus NRS4, while the safety of treatments was evaluated in terms of the number of patients who had ≥1 AE and who had at least one SAE.

Results

A total of 37 studies with 43 cohorts that examined 9 medications and placebo and involved 18172 participants were included. Compared with the placebo, all biologics and JAK inhibitors were associated with a higher response rate in efficacy outcomes, while systematic administration was presented by dupilumab 200 mg subcutaneously every 2 weeks with superior improvement in EASI 90 (RR 9.50, 95 % CI 2.31-39.03) and IGA0/1 (RR 17.00, 95 % CI 2.33-123.78), upadacitinib 30 mg once daily in EASI 75 (RR 5.14, 95 % CI 4.20-6.31) and Pruritus NRS4 (RR 5.73, 95 % CI 4.44-7.39), and external use was presented by ruxolitinib 1.5 % twice daily orally in EASI 75 (RR 4.14, 95 % CI 3.06-5.61) and Pruritus NRS4 (RR 4.08, 95 % CI 2.86-5.81), and most of doses led to a better safety profile. Most doses of baricitinib, dupilumab, tralokinumab, and upadacitinib in combination with TCS demonstrated good efficacy as compared with the control groups (placebo + TCS). However, patients receiving baricitinib at a dosage of 2 mg daily (RR 1.23, 95 % CI 1.02-1.49) and 4 mg daily (RR 1.39, 95 % CI 1.22-1.58) in combination with TCS, exhibited a higher incidence of one or more SAE as compared with those taking placebo + TCS.

Conclusion

Our research has revealed that ruxolitinib and dupilumab are effective and safe treatments for mild to moderate AD and moderate to severe AD, respectively. Additionally, the combination of dupilumab and TCS demonstrates greater efficacy and safety compared to baricitinib, tralokinumab, and upadacitinib with TCS as a background treatment for moderate to severe AD. We suggest that the use of topical JAK inhibitors could be a potential alternative to TCS when used in combination with systemic medications, as a novel approach to treat AD. Insufficient different data sources caused by partial interventions were only mentioned in a few articles and low event rates in safety analyses may lead to the results being biased. Further studies directly comparing existing and novel treatments are needed and will be included in forthcoming updates of this review. Our findings could form a useful foundation for developing a new generation of treatment guidelines for AD.

Tuberculous Lymphadenitis in a Patient Treated with Dupilumab: A Case Report

Tuberculous lymphadenitis is among the most frequent presentations of extrapulmonary tuberculosis; the most common presentation is isolated chronic non-tender lymphadenopathy in young adults without systemic symptoms. Dupilumab is a fully human monoclonal antibody directed against interleukin-4 receptor-α that blocks the synergistic effects of interleukin-4 and interleukin-13 on allergic inflammation. Its well-known adverse events are allergic conjunctivitis, injection site reaction, and dupilumab facial redness. A 32-year-old female with severe atopic dermatitis was treated with dupilumab for 2 months at our clinic. She complained of multiple enlarged palpable lymph nodes on the right side of the neck and inguinal area for 2 months. Laboratory tests showed an increased total eosinophil count and immunoglobulin E level, as well as positive interferon-γ release assays. Radiological examination showed multiple low echoic and heterogeneous well-enhancing lymph nodes in level II, III, IV, and V of the neck. Histological examination revealed caseous necrosis and tuberculoid granuloma. The lymph node enlargements were completely relieved after antituberculosis treatment. The mechanism for the development of tuberculous lymphadenitis in a patient receiving dupilumab is not fully understood yet. In some previous studies, treatment with dupilumab suppressed the expression of genes related not only to T helper 2 and eosinophil response but also to proinflammatory responses. It could not inhibit the intracellular growth of Mycobacterium tuberculosis in macrophages, predisposing them to the development of tuberculous infection. To the best of our knowledge, this is the first report on the development of tuberculosis lymphadenitis in a patient treated with dupilumab.

Long-term Effectiveness and Safety of Upadacitinib for Atopic Dermatitis in a Real-world Setting: An Interim Analysis Through 48 Weeks of Observation

BACKGROUND

Janus kinase (JAK) inhibitors, including upadacitinib, have been recently approved for the treatment of moderate-severe atopic dermatitis (AD) and real-world data on upadacitinib effectiveness and safety are limited. This interim analysis aimed to assess effectiveness and safety of upadacitinib throughout 48 weeks of observation in a real-world adult AD population.

METHODS

This prospective study collected data on adult patients affected by moderate-to-severe AD and treated with upadacitinib at the dosage of either 15 mg or 30 mg daily based on the physician decision. Upadacitinib was prescribed in the context of a national compassionate use programme. In this interim analysis, within patient comparisons of continuous scores of different scales (namely Eczema Area and Severity Index [EASI], body surface area [BSA], Dermatology Life Quality Index [DLQI], Patient Oriented Eczema Measure [POEM], Numeric Rating Scale [NRS] subtests) were performed. The percentage of patients achieving EASI 75, EASI 90 and EASI 100 at Week 16, 32 and 48 was also evaluated.

RESULTS

One hundred and forty-six patients were included in the analysis. Upadacitinib 15 mg or 30 mg daily was prescribed as monotherapy in most cases (127/146, 87.0%). Upadacitinib was initially prescribed at the dosage of 30 mg daily in 118 of 146 (80.8%) patients and 15 mg daily in 28/146 (19.2%) patients. A significant improvement in the clinical signs and symptoms of AD was detected by Week 16 and throughout the study period. EASI 75, EASI 90 and EASI 100 responses were achieved by 87.6%, 69.1% and 44.3% at Week 48, associated with a sustained reduction in the mean values of all physician-reported (EASI and BSA) and patient-reported (Itch- Sleep- and Pain-NRS, DLQI, and POEM) disease severity outcomes, up to 48 weeks of treatment. Treatment response observed in 15 mg upadacitinib-treated patients was comparable with that detected in 30 mg upadacitinib-treated patients, revealing no statistical difference between the two patient sub-cohorts. Through the observation period, dose reduction or escalation was observed in 38/146 (26%) of treated cases. Overall, 26 of 146 (17.8%) patients experienced at least one adverse event (AE) during the treatment period. In total, 29 AEs were recorded and most of them were evaluated as mild to moderate, while in 4 cases the occurrence of AE led to drug discontinuation, for a total of 7/146 (4.8%) dropouts.

CONCLUSION

This study provides strong evidence of a sustained response obtained by upadacitinib in AD patients, who had failed to respond to conventional or biological systemic agents, through 48 weeks of observation. Upadacitinib was also demonstrated to be advantageous in terms of flexibility in dose reduction or escalation as upadacitinib dose was shaped on clinical needs that, in a real-world setting, might frequently change.

Consensus on the therapeutic management of atopic dermatitis ‒ Brazilian Society of Dermatology: an update on phototherapy and systemic therapy using e-Delphi technique

This publication is an update of the "Consensus on the therapeutic management of atopic dermatitis - Brazilian Society of Dermatology" published in 2019, considering the novel, targeted-oriented systemic therapies for atopic dermatitis. The initial recommendations of the current consensus for systemic treatment of patients with atopic dermatitis were based on a recent review of scientific published data and a consensus was reached after voting. The Brazilian Society of Dermatology invited 31 experts from all regions of Brazil and 2 international experts on atopic dermatitis who fully contributed to the process. The methods included an e-Delphi study to avoid bias, a literature search and a final consensus meeting. The authors added novel approved drugs in Brazil and the indication for phototherapy and systemic therapy for AD. The therapeutical response to systemic treatment is hereby reported in a suitable form for clinical practice and is also part of this updated manuscript.

Dupilumab Safety and Efficacy in a Phase III Open-Label Extension Trial in Children 6-11 Years of Age with Severe Atopic Dermatitis

BACKGROUND

For children aged 6-11 years with uncontrolled severe atopic dermatitis (AD), 16 weeks of treatment with dupilumab resulted in substantial clinical benefit compared with placebo with an acceptable safety profile. However, longer-term safety and efficacy data are important to inform longitudinal AD management.

OBJECTIVES

This analysis of data from an open-label extension study (LIBERTY AD PED-OLE, NCT02612454) reports the long-term safety, efficacy, and pharmacokinetics of dupilumab in children with severe AD who had participated in the pivotal dupilumab LIBERTY AD PEDS study (NCT03345914).

METHODS

Enrolled patients initially received subcutaneous dupilumab 300 mg every 4 weeks (q4w). The q4w regimen could be uptitrated to dupilumab dose regimens of 200 or 300 mg every 2 weeks (q2w; for body weight < 60 or ≥ 60 kg, respectively) for patients who did not achieve an Investigator's Global Assessment (IGA) score of 0/1 (clear/almost clear skin) at week 16, or prior to week 16 as rescue treatment. Additional patients were uptitrated to a weight-tiered q2w regimen following a protocol amendment. Patients who maintained an IGA score of 0/1 continuously for a 12-week period after week 40 discontinued dupilumab. They were monitored for relapse and were reinitiated on dupilumab if required.

RESULTS

Data for 321 patients (mean age 8.6 years) were analyzed, 254 (79%) of whom had completed the scheduled 52-week visit at the database lock. Most treatment-emergent adverse events were mild/moderate. By week 52, 41% of patients achieved an IGA score of 0/1, and 97%, 82%, and 50%, respectively, had at least a 50%, 75%, and 90% improvement from the parent study baseline in Eczema Area and Severity Index (EASI). By week 52, 29% of patients in the overall population had clear/almost clear skin sustained for 12 weeks and had stopped medication; of these, 40% relapsed and were subsequently reinitiated on treatment, with a mean time to reinitiation of 13.5 (standard deviation 5.2) weeks. Following reinitiation of dupilumab, 41% of the patients with evaluable data at the time of database lock had regained an IGA 0/1 clinical response.

CONCLUSIONS

Consistent with results seen in adults and adolescents, long-term treatment with dupilumab in children aged 6-11 years with severe AD showed an acceptable safety profile and incremental clinical benefit. A substantial proportion of children who stopped dupilumab treatment after achieving clear/almost clear skin subsequently experienced disease recurrence, and required reinitiation of dupilumab, suggesting that continuous treatment may be necessary for maintenance of clinical benefit.

Predictive Factors of Early Response to Dupilumab in Patients with Moderate-to-Severe Atopic Dermatitis

Efforts have been made to identify factors influencing clinical response in patients with atopic dermatitis (AD) treated with dupilumab. A retrospective single-center observational study was carried out by analyzing data from 492 patients aged 12 years and older with moderate-to-severe AD. The study aimed to identify baseline demographic and clinical factors that could predict the achievement of a mild level of disease, i.e., an Eczema Area and Severity Index (EASI) ≤ 7, within 4 weeks from dupilumab initiation. Classic, generalized lichenoid and inflammatory phenotypes compared with a nummular eczema phenotype (OR = 6.9, 95% CI 2.04-23.48 and OR = 4.22, 95% CI 1.22-14.66, respectively) and a baseline EASI ≤ 24 and between 24-29, compared with a baseline EASI ≥ 29 (OR = 3.1, 95% CI 1.81-5.41 and OR = 1.8, 95% CI 1.05-3.07, respectively), were found to be predictive factors of early response to dupilumab, highlighting the importance of early biological treatment of AD.

Current and Emerging Therapies for Atopic Dermatitis in the Elderly

Atopic dermatitis (AD) in the elderly has recently emerged as a distinct subgroup of AD, garnering widespread concern due to its increasing global incidence rate. Epidermal barrier dysfunction, inflammatory response, and chronic pruritus interact with each other, contributing to the pathogenesis and pathophysiology of AD in the elderly. Although fundamental medications are essential for managing AD in the elderly, older adults often struggle with regular usage of moisturizing emollients, topical medications, and avoidance of environmental triggers, leading to recurrent or even exacerbated disease progression. Therefore, a systematic medication approach is necessary to control pruritus and skin lesions. Traditional systemic treatments may not adequately meet the treatment needs of moderate and severe AD in the elderly and may even pose certain safety risks. Biologics and Janus kinase (JAK) inhibitors, exhibiting excellent clinical efficacy, have made significant breakthroughs in AD treatment. Existing evidence suggests that dupilumab, a human monoclonal IgG4 antibody, has been confirmed as an effective and safe first-line systematic treatment for moderate to severe AD in the elderly, with no notable differences between adults and the elderly. However, the limited inclusion of elderly patients in related clinical studies hinders the generalizability of these findings. As older patients face a higher risk of adverse events with JAK inhibitors, JAK inhibitors are recommended when no other suitable treatment options are available. Obtaining population-specific data is crucial for making evidence-based treatment choices when managing AD in older adults with JAK inhibitors.

[Efficacy of dupilumab in real practice in the treatment of severe forms of asthma and atopic dermatitis (comparative retrospective study)]

BACKGROUND

Dupilumab, a fully human monoclonal antibody directed against the common α-subunit of interleukin (IL)-4 receptors and blocking signaling from both IL-4 and IL-13, may be recommended for the treatment of moderate to severe atopic dermatitis (AD) and bronchial asthma (BA).

AIM

To perform a comparative assessment of the effectiveness of maintenance therapy with dupilumab in patients with severe BA as the main indication for genetically engineered biological drugs and in patients with severe asthma with concomitant severe AD as the indication for targeted therapy.

MATERIALS AND METHODS

A 6-month retrospective comparative study was performed at the specialized reference center for allergology and immunology. The study included 115 adult patients of both sexes treated with dupilumab for uncontrolled severe asthma as the main indication for targeted therapy (BA group; n=65) or for a combination of severe uncontrolled asthma and severe AD (BAAD; n=50). Dupilumab was administered subcutaneously for 6 months. The first dose was 600 mg once and then 300 mg Q2W. Evaluation of the effectiveness of dupilumab therapy at 6 months of treatment in both groups included achieving asthma control (ACT, ACQ5), improving pulmonary function test, reducing the risk of exacerbations and the need for systemic glucocorticosteroids (SGCS), improving quality of life (AQLQ), change of biomarkers (FeNO, eosinophil count) and the course of comorbid diseases, including improvement in the AD (SCORAD, EASI) and rhinosinusitis polyposa (SNOT-22).

RESULTS AND CONCLUSION

During dupilumab therapy, in a significant proportion of patients, regardless of the presence or absence of other T2-associated diseases (e.g., AD or rhinosinusitis polyposa), an improvement in asthma was demonstrated as early as in the first 6 months of treatment with dupilumab in all recommended domains for assessing the response to targeted therapy: improving asthma control and respiratory function, reducing the frequency of moderate and severe exacerbations associated with the use of SGCS and/or hospitalization, a positive effect on the quality of life and the comorbid diseases, as well as a cumulative reduction in the need for SGCS.

Analyses of Dupilumab-Related Ocular Adverse Drug Reactions Using the WHO's VigiBase

INTRODUCTION

Dupilumab is a drug that inhibits the action of interleukin (IL)-4 and IL-13 and is a potent therapeutic drug for allergic diseases such as atopic dermatitis. Although its use has been associated with significant ocular adverse drug reactions (ADRs), the IL-4 and IL-13 inhibition may also have favorable therapeutic effects. The aim of this study was to determine the disease spectrum in which the use of dupilumab may have been associated with an increase or decrease of ocular ADRs.

METHODS

We searched the World Health Organization's VigiBase for ADRs associated with the use of dupilumab for data up to 12 June 2022. The number of all ADRs that were retrieved was compared with the number of ocular ADRs associated with the use of dupilumab. Disproportionate reporting was assessed by calculating the information component (IC) values and odds ratios.

RESULTS

Since the introduction of dupilumab, 100,267 ADRs have been reported. Of all the ADRs associated with dupilumab, 28,522 ADRs were ocular complications, and it ranked fourth in the ocular complications by organ level. By assessments of the IC for age ≤ 44 years, the most significantly associated ADRs were dry eye followed by blepharitis including eyelid crusting and dryness and conjunctivitis. Crusting and dryness of the eyelids were the most significant ADRs for all age groups. Other ocular ADRs reported include meibomian gland dysfunction, keratitis, glaucoma, and retinal disorders. In contrast, periorbital edema, neuro-ophthalmic disorders, optic neuritis, and macular edema were significantly reduced by the use of dupilumab.

CONCLUSIONS

Dupilumab-related ADRs included an increase or decrease of various ocular disorders. The results indicate that dupilumab also has potential therapeutic effects.

Dupilumab-associated ocular adverse events are predicted by low tear break-up time and correlate with high IL-33 tear concentrations in patients with atopic dermatitis

Dupilumab, blocking IL-4 and IL-13 signals, improves atopic dermatitis and Quality of Life but might be also associated with the occurrence of ocular adverse events (OAEs). The main objective of our prospective study was to characterize the cytokine and chemokine profile in the tear fluid of dupilumab-treated patients with moderate-to- severe atopic dermatitis and to identify biomarkers predicting the occurrence of ocular adverse events. Patients with moderate-to-severe AD underwent dermatological and ophthalmological evaluation at the baseline (T0) and week 16 or at the time of an eventual ocular adverse events (T1). A multiplex immunoassay measuring multiple cytokines and chemokines in the tear fluid extracted during ocular examination at both T0 and T1 was performed. Thirty-nine patients with moderate-to-severe AD and treated with dupilumab were included in the study. Baseline tear fluid levels revealed a significantly higher concentration of type 2 cytokines and chemokines in AD patients than healthy controls. The occurrence of ocular adverse events during dupilumab therapy was associated with a significant increase of IL-33 tear fluid levels and a significantly lower tear break-up time, this latter also identified as predictive factor. Our findings suggest that the ophthalmological examination should be considered a valid support to identify patients at risk of developing OAEs and to provide their appropriate management.

Anti-inflammatory and biologic drugs for atopic dermatitis: a therapeutic approach in children and adolescents

Atopic dermatitis (AD) is a chronic inflammatory disease with a heterogeneous pathogenesis correlated with dysregulation of the immune system and a prevalence of the T2-mediated immune pathway. Recent understanding of the pathogenesis of AD has allowed the development of new drugs targeting different mechanisms and cytokines that have changed the treatment approach. The aim of this review is to update knowledge on the standard of care and recent advancements in the control of skin inflammation. In light of recent guidelines, we report on the clinical efficacy of novel treatments, with special attention to situations where biologics and small molecules are involved.

Comparison of Efficacy of Baricitinib and Dupilumab in the Treatment of Chinese Moderate-To-Severe Atopic Dermatitis: A Retrospective Study

INTRODUCTION

The treatment of atopic dermatitis (AD) patients with insufficient response or intolerance to topical medication remains clinical challenges, and there is a paucity of head-to-head trials comparing the efficacy of novel biological agents such as JAK inhibitor and antibody.

METHODS

To compare the efficacy of selective JAK1/JAK2 inhibitor baricitinib and interleukin-4 monoclonal antibody dupilumab in the treatment of patients with moderate-to-severe AD, a retrospective cohort study method was adopted. Clinical data from June 2020 to April 2022 were systematically reviewed. Eligible patients who received baricitinib or dupilumab were screened according to the following inclusion criteria: (1) age ≥ 18 years; (2) moderate-to-severe AD: baseline investigator global assessment (IGA) score ≥ 3, baseline eczema area and severity index (EASI) score ≥ 16; (3) poor response or intolerance to at least one topical drug in the past 6 months; (4) no topical glucocorticoids were used in the past 2 weeks and no systematic treatment was given in the past 4 weeks. Patients of the baricitinib group were treated with oral baricitinib in doses of 2 mg per day for 16 weeks, and patients of the dupilumab group were treated with standardized use of dupilumab for 16 weeks, with the initial 600 mg subcutaneous injection and the following 300 mg subcutaneous injection every 2 weeks. The clinical efficacy score indexes including the IGA score, EASI score, and Itch Numeric Rating Scale (NRS) score. These scores at 0, 2, 4, 8, 12, and 16 weeks after the start of treatment were collected.

RESULTS

A total of 54/45 patients treated with baricitinib/dupilumab were included. There was no significant difference in the decrease of all scores between the two groups at the 4th week (p > 0.05). There was no difference in the EASI score and Itch NRS score (p > 0.05), but the IGA score of the baricitinib group was lower at the 16th week (Z = 4.284, p < 0.001). Within the first 4 weeks, the Itch NRS score of the baricitinib group decreased rapidly, but with the prolongation of treatment time, there was no significant difference between the two groups at the 16th week (Z = 1.721, p = 0.085).

CONCLUSIONS

The efficacy of baricitinib at a dose of 2 mg daily was similar to dupilumab, and the improvement in pruritus was significantly faster in the early stage of treatment (the first 4 weeks) than that of dupilumab.

Biologic Versus Small Molecule Therapy for Treating Moderate to Severe Atopic Dermatitis: Clinical Considerations

The U.S. Food and Drug Administration approval of dupilumab for moderate-to-severe atopic dermatitis shifted the paradigm from use of broad, systemic immunosuppressants to a safer, targeted treatment and led to the emergence of newer interleukin (IL)-4/IL-13 directed biologics and small molecule therapies, namely Janus kinase (JAK) inhibitors (JAKi). Tralokinumab and emerging (not yet approved) lebrikizumab, which both target IL-13, are alternative biologics to dupilumab. The emerging anti-IL-31 receptor nemolizumab is likely to be used second-line to other biologics, primarily for pruritus. Three JAKi are currently in use for treating atopic dermatitis, 2 of which, abrocitinib and upadacitinib, are U.S. Food and Drug Administration-approved. This review provides an in-depth, practical discussion on use of these biologics and JAKi that are approved or have completed phase 3 clinical trials in pediatric patients and adults, comparing the groups of medications based on available efficacy and safety data.

Effectiveness and safety of dupilumab in adults with moderate and severe atopic dermatitis in Colombia: Real-life experience

Background

Dupilumab is a treatment approved for uncontrolled moderate-to-severe atopic dermatitis (AD). Tropical and developing countries such as Colombia have characteristics that may impact the natural history of AD and access to medical treatments. In that sense, we aimed to describe the effectiveness and safety of dupilumab in adults with moderate to severe AD in a Colombian multicenter cohort.

Methods

Multicenter descriptive study that included patients who started treatment between March 2018 and May 2020 in 6 centers. Disease severity was assessed using the following: Scoring Atopic Dermatitis (SCORAD), Eczema Area and Severity Index (EASI), Patient Oriented Eczema Measure (POEM), and Dermatology Life Quality Index (DLQI). These measurements were collected according to availability at baseline, 3-5 months, 6-12 months, and more than 12 months. Days of sick leave, hospitalizations, and AD flares before and after dupilumab treatment were reported. Adverse events (AEs) were recorded during follow-up.

Results

Ninety-three patients were included, with a median age of 32 years (IQR: 24.0; 40.0) and a disease evolution time of 21 years (IQR: 16.0; 29.5). 88.2% had at least 1 allergic disease other than AD. An improvement greater than or equal to 75% EASI was observed in 41.7% of patients at 3-5 months, in 73.7% of patients at 6-12 months, and in 75.0% of patients after 12 months. For those reporting SCORAD and POEM, the median percent change ([IQR], n) from baseline in SCORAD was -67.1 ([-79.2; -54.2], n = 16), -70.5 ([-85.8; -47.9], n = 36) and -66.7 ([-77.3; -51.0], n = 13); and POEM, -58.6 ([-66.4; -55.5], n = 4), -73.0 ([-86.5; -66.7], n = 16) and -87.3 ([-93.4; -69.6], n = 8), respectively. Before initiation of dupilumab treatment, 82 (88.2%) patients reported at least 1 flare of AD in the past 12 months. During the follow-up period, 30 (32.3%) patients reported at least 1 exacerbation or flare. Twelve patients (12.9%) presented an AE and 3 (3.2%) patients discontinued dupilumab for this cause.

Conclusions

Dupilumab was effective and safe for the treatment of moderate to severe AD in point-of-care settings, with results similar to randomized controlled and other real-life studies. These positive results are still maintained even though a high number of patients had short interruptions in the use of dupilumab due to administrative problems.

Dupilumab-Induced, Tralokinumab-Induced, and Belantamab Mafodotin-Induced Adverse Ocular Events-Incidence, Etiology, and Management

ABSTRACT

Emerging monoclonal antibody therapies are assuming greater importance in the management of severe and refractory forms of immunity-driven and oncological disorders. However, some have been found to induce adverse ocular events (AOEs) leading to discontinuation of treatment or additional multidisciplinary management. We present the current knowledge concerning AOEs associated with 3 monoclonal antibody therapies: dupilumab, tralokinumab, and belantamab mafodotin. We examine the manifestations of their AOEs, proposed pathophysiological mechanisms, and current treatment recommendations. We identified and reviewed all studies for dupilumab, tralokinumab, and belantamab mafodotin using the keywords "dupilumab," "tralokinumab," "belantamab mafodotin," "conjunctivitis," and "keratopathy" from January 2016 to November 2021. Conjunctivitis was the most frequently reported AOE in patients with atopic dermatitis receiving dupilumab or tralokinumab. Mild cases were managed with warm compresses for associated meibomian gland dysfunction, artificial tears, and antihistamine/mast cell stabilizer eye drops. In more severe cases, additional anti-inflammatory therapy, with corticosteroid eye drops or ointments, or topical calcineurin inhibitors-such as tacrolimus or ciclosporin-were required. Patients with resistant or refractory multiple myeloma treated with belantamab mafodotin often developed keratopathy, which could necessitate contact lens fitting, or for cycles of belantamab mafodotin to be delayed.

A real-world observational study of dupilumab treatment in adult patients with prurigo nodularis

BACKGROUND

Prurigo nodularis (PN) is a chronic inflammatory skin condition that has a significant unmet needs for effective treatment options.

OBJECTIVE

To assess the efficacy and safety of dupilumab in adult patients with PN refractory to traditional therapies.

METHODS

This ongoing, real-life study examined dupilumab treatment in 8 adult patients diagnosed with PN for at least 6 months. The included patients were prescribed 300 mg dupilumab biweekly for at least 16 weeks. Efficacy was the primary outcome by means of multiple standardized scale measurements while safety was also reported.

RESULTS

PN patients treated with dupilumab showed notable clinical improvement. After 16 weeks of dupilumab treatment, the mean Investigator Global Assessment (IGA) score reduced from 3.75 to 1.50. Patients mean Numerical Rating Scale Itch Intensity (NRSI), Dermatology Life Quality Index (DLQI), and Hospital Anxiety and Depression Scale (HADS) ratings reduced from 8.625, 15.13, and 14.50 to 1.563, 4.625, and 1.000 respectively. The majority of the patients (87.5%) reported dupilumab as effective while no adverse events have been reported.

STUDY LIMITATIONS

This study was limited to a small cohort of adult PN patients and a short-time observation period.

CONCLUSIONS

Dupilumab is effective and tolerable in adult PN patients with significant improvement in skin lesions, itching, and quality of life.
