Fifty‐two week follow‐up safety and effectiveness results of dupilumab treatment of moderate‐to‐severe atopic dermatitis from a retrospective, multicentric series

Real-World Experience of 3-Year Treatment With Dupilumab: Significant Decrease in Circulating Neutrophils and Eosinophils in Japanese Patients With Atopic Dermatitis

Dupilumab, an anti-interleukin (IL)-4 receptor α-antibody, was approved in 2018 for the treatment of moderate-to-severe atopic dermatitis (AD) in Japan. Although real-world data have accumulated on the effectiveness and safety of dupilumab in patients with AD in the short term, real-world data on its long-term use are limited. In this study, we retrospectively investigated its effectiveness, safety and laboratory data in patients with AD who received dupilumab for 3 years. All adult patients with moderate-to-severe AD who were administered dupilumab between June 2018 and December 2020 and were treated with dupilumab for more than 3 years were included in this study. Sixty Japanese patients with AD (male, 48; female, 12) were included in this study. Their mean age was 36.6 ± 11.0 (standard deviation) years. The mean Eczema Area and Severity Index (EASI) was 29.9 ± 9.2. The clinical severity scales, including Investigator's Global Assessment (IGA), EASI and affected body surface area (BSA), and patient-reported outcomes, such as Dermatology Quality Life Index (DLQI), Patient-Oriented Eczema Measure (POEM) and visual analogue scale (VAS) of pruritus, significantly improved at 3 months, and at 1, 2 and 3 years after initiating dupilumab. The total EASI score significantly decreased by a mean of 66.8% at 3 months, 81.0% at 1 year, 85.3% at 2 years and 90.0% at 3 years after initiating dupilumab. The serum levels of thymus and activation-regulated chemokine (TARC), immunoglobulin E (IgE) and lactate dehydrogenase (LDH) significantly decreased at 1, 2 and 3 years. A slight decrease in circulating neutrophils was observed in patients with AD treated with dupilumab over periods from 3 months to 3 years. The number of circulating eosinophils significantly decreased at 2 and 3 years after initiating dupilumab. The most common adverse event was ocular disorders observed in 23 patients (38.3%). Our study shows the sustained effectiveness and tolerable safety of 3-year usage of dupilumab in Japanese patients with atopic dermatitis. Furthermore, dupilumab decreased neutrophil values at 3 months and later, and reduced the number of circulating eosinophils after long-term use (≧ 2 years).

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.

Assessment of potential predictive factors of dupilumab response in patients with moderate-to-severe atopic dermatitis

BACKGROUND

Dupilumab has shown to be an effective and safe treatment for patients with moderate-to-severe atopic dermatitis (AD).

OBJECTIVE

To evaluate the predictive factors of response (PRF) in patients with moderate-to-severe AD treated with dupilumab.

METHODS

Observational, retrospective and multicentre study conducted on adult patients diagnosed with moderate-to-severe AD treated with dupilumab, with a post-treatment follow-up of at least 16 weeks. The primary endpoints were EASI-75 and the IGA scale at week 52.

RESULTS

A total of 198 patients were included in the analysis. Mean age was 38 ± 15.1 years and 116 (58.6%) were men. The most prevalent AD-predominant phenotypes were flexural eczema (45.3%), head-and-neck eczema (18.2%) and erythroderma (17.7%). At week 52, 140 (86.4%) patients achieved EASI-75 and 119 (93.0%) achieved an improvement in ≥2 points from baseline in IGA score. Women were 3.6 times more likely to achieve EASI-75 response than men (Odds ratio: 3.58; p = 0.020). While increased body mass index significantly reduced the probability of obtaining an improvement of ≥2 points in the IGA scale at week 52 (odds ratio: 0.88; p = 0.049).

CONCLUSIONS

Dupilumab was an effective treatment in patients with moderate-to-severe AD. Additionally, sex and body mass index were significantly associated with achieving EASI-75 and an improvement of ≥2 points in the IGA scale, respectively, at week 52.

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.

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.

Efficacy of hydrotherapy, spa therapy, and balneotherapy for psoriasis and atopic dermatitis: a systematic review

BACKGROUND

Atopic dermatitis (AD) and psoriasis are chronic inflammatory diseases that have significant skin complications.

OBJECTIVE

The purpose of this systematic study was to evaluate the evidence obtained from human studies on the effects of hydrotherapy, spa therapy, and balneotherapy in psoriasis and atopic dermatitis.

METHODS

The present systematic review was conducted according to the guidelines of the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statements. Also, for this study databases such as Embase, PubMed, Scopus ProQuest, and sciences direct database were searched from the beginning to April 2021.

RESULTS

All human studies that examined the effect of balneotherapy, spa therapy, and hydrotherapy on psoriasis and atopic dermatitis were published in the form of a full article in English. In the end, only 22 of the 424 articles met the criteria for analysis. Most studies have shown that balneotherapy, spa therapy, and hydrotherapy may reduce the effects of the disease by reducing inflammation and improving living conditions. In addition, the results of the Downs and Black score show that seven studies received very good scores, three studies received good scores, nine studies received fair scores, and three studies received poor scores.

CONCLUSIONS

The results of studies also showed that hydrotherapy leads to an improvement in the PASI score index. Nevertheless, more clinical trials are needed to determine the mechanism of action of hydrotherapy on these diseases.

Effectiveness and Safety of Upadacitinib in the Treatment of Moderate-Severe Atopic Dermatitis: A Multicentric, Prospective, Real-World, Cohort Study

Background

The efficacy and safety of upadacitinib in atopic dermatitis (AD) have been defined in clinical trials, but no real-world data are currently available. We aimed to assess the safety and effectiveness of upadacitinib in a real-world AD patient cohort that mostly included patients who failed the available systemic therapies, including dupilumab.

Methods

Prospective cohort study collecting data on upadacitinib-treated AD adult patients completing at least 16 weeks of therapy.

Results

Forty-three patients showed rapid and marked response to upadacitinib with significant reduction of all disease severity scores since the first follow-up visit. At week 16, Eczema Area and Severity Index (EASI) 75, EASI 90, and EASI 100 response was observed in 97.5%, 82.1%, and 69.2% of patients, respectively. EASI 90 response reflected the achievement of a clear or almost clear condition (POEM 0-2), self-evaluated by 79.5% of patients. Patients’ quality of life improved as suggested by the achievement of DLQI 0/1 by 38.5% of patients at week 4, and by 76.9% at week 16.

Conclusion

Elevated effectiveness and favorable safety of upadacitinib were confirmed in patients unresponsive to dupilumab, who were not included in upadacitinib trials.

Long-term real-world experience of the side effects of dupilumab in 128 patients with atopic dermatitis and related conditions aged 6 years and above: retrospective chart analysis from a single tertiary care center

BACKGROUND

Dupilumab is a monoclonal antibody against interleukins 4 and 13 currently FDA approved for the treatment of moderate to severe atopic dermatitis (AD) in adults and adolescents and severe AD in children aged 6-11 years. It is reported to be safe with the most common side effects described from clinical trials being conjunctivitis, nasopharyngitis, and injection site reactions. Outside the clinical trial settings, there is insufficient data on the side effects of dupilumab in adults with AD, and much less among children and adolescents. The aim of this study was to analyze the spectrum of side effects in all patients receiving dupilumab for the treatment of AD and related conditions in a real-world setting at a single tertiary referral center, and corelate any risk factors for the development of these side effects.

METHODOLOGY

A retrospective review of electronic medical records was conducted for all patients who had received dupilumab for a minimum of 2 months for the treatment of AD and related conditions in the department of dermatology at Rashid hospital, Dubai from February 2018 to November 2021.

RESULTS

We analyzed the medical records of 128 patients who received dupilumab according to standard age-related dosing. This included 78 adults (age range 18-81 years) and 50 children and adolescents (aged 6-17 years). There were 73 males and 55 females. The mean duration of dupilumab treatment was 14.9 months. The most common side effects encountered during dupilumab therapy were head and neck dermatitis in 25 (19.5%), conjunctivitis in 20 (15.6%), erythema, pruritus and peeling of skin in 14 (10.9%) and dryness of eyes in 10 (7.8%) patients, respectively.

CONCLUSION

Overall, dupilumab was well-tolerated in our patient population. Most of the side effects were mild and did not require discontinuation of dupilumab. These findings would enable dermatologists understand the side effects of dupilumab better resulting in improved treatment plan decisions in clinical practice.

Dupilumab-associated ocular manifestations: A review of clinical presentations and management

Dupilumab is a first-in-class biologic approved by the European Medicines Agency (EMA) and the US Food and Drug Administration (US FDA) for the treatment of multiple atopic diseases, including atopic dermatitis, asthma, and chronic rhinosinusitis with nasal polyposis. Since gaining traction as an effective treatment modality, multiple reports have highlighted the many ocular side effects associated with dupilumab usage. These range from mild diseases such as conjunctivitis, dry eyes, and blepharitis, to more severe manifestations such as intraocular inflammation and cicatrising conjunctivitis. The pathogenesis behind these manifestations remains controversial but are likely multi-factorial. We review the current evidence surrounding ocular manifestations of dupilumab-associated disease and proposed treatments to provide an overview of this unique disease entity. With increasing usage of dupilumab, formal recommendations regarding the treatment of dupilumab-associated ocular disease are warranted to provide standardised clinical guidance. Furthermore, it is important for healthcare practitioners to remain abreast with existing literature to adequately counsel and empower patients with the knowledge surrounding contemporary treatments for atopic diseases and their associated side-effects.

Dupilumab ocular side effects in patients with atopic dermatitis: a systematic review

Atopic dermatitis (AD) is a chronic, inflammatory skin disorder that most frequently occurs in children, but it can also affect adults. Even though most AD cases can be managed with topical treatments, moderate-to-severe forms require systemic therapies. Dupilumab is the first human monoclonal antibody approved for the treatment of AD. Its action is through IL-4 receptor alpha subunit inhibition, thus blocking IL-4 and IL-13 signaling pathways. It has been shown to be an effective, well tolerated therapy for AD, as well as for asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP) and eosinophilic esophagitis (EoE). However, an increasing incidence of Dupilumab-induced ocular surface disease (DIOSD) has been reported in patients treated with Dupilumab, as compared to placebo. The aim of this study was to summarize scientific data regarding DIOSD in AD patients treated with Dupilumab. A search of PubMed and clinicaltrials.gov databases was performed. There was no limit to study design. All AD cases were moderate-to-severe. DIOSD was either dermatologist-, allergist-, or ophtalmologist-assessed. Evidence shows that DIOSD occurs most frequently in patients with atopic dermatitis and not in other skin conditions, neither in patients with asthma, CRSwNP, nor EoE who are on Dupilumab treatment. Further studies are warranted in order to establish a causal relationship between Dupilumab and ocular surface disease. Nevertheless, ophtalmological evaluations prior to Dupilumab initiation can benefit AD patients with previous ocular pathology or current ocular symptomatology. Also, patch testing for ocular allergic contact dermatitis might be advantageous in patients with a history of allergic conjunctivitis. Furthermore, TARC, IgE and circulating eosinophils levels might be important biomarkers for a baseline assessment of future candidates to Dupilumab treatment. However, TARC measurements should be resumed for research purposes only.

A 52 weeks dupilumab treatment for moderate to severe atopic dermatitis in Korea: long-term efficacy and safety in real world

Previously, we have reported short term effectiveness and safety of dupilumab in Korea. In this study, we are trying to report the long-term effectiveness and safety of dupilumab in Korea. Ninety-nine patients with moderate to severe AD were analyzed. They were evaluated using Eczema Area and Severity Index (EASI), Numerical Rating Scale (NRS), Patient Oriented Eczema Measure (POEM), and Dermatology Quality of Life Index (DLQI) at baseline, week 16, 32 and 52. Efficacy outcomes showed higher improvement at 52 weeks compared with 16 weeks; high percentual reductions in EASI (88.1%), peak pruritus NRS (65.6%), POEM (67.2%), and DLQI (69.0%) compared to baseline. Proportion of patients achieving EASI 75 and 90 were 90.2% and 53.7%. POEM and DLQI had high correlation with clinical measured outcomes. In the analysis for the factors affecting achievement of EASI 90, female gender (OR 2.5), eosinophilia (OR 0.2) and elevated LDH (OR 0.07) were significantly associated. Most frequent adverse events included facial erythema (19.2%) and conjunctivitis (17.2%), which were mild/moderate and resolved during treatment. In conclusion, dupilumab treatment for 52 weeks in Korean patients with moderate-to-severe AD confirmed long term effectiveness and safety.

Effectiveness and Safety of Long-Term Dupilumab Treatment in Elderly Patients with Atopic Dermatitis: A Multicenter Real-Life Observational Study

OBJECTIVE

The objective of this study was to assess the effectiveness and safety of dupilumab in treating elderly patients with atopic dermatitis from baseline to 52 weeks.

METHODS

A retrospective observational real-life study was conducted in a group of elderly patients with severe atopic dermatitis treated with dupilumab for 52 weeks. Inclusion criteria were: age ≥ 65 years; diagnosis of atopic dermatitis made by an expert dermatologist; Eczema Area and Severity Index ≥ 24; and a contraindication, side effects, or failure to respond to cyclosporine. The primary outcome was the mean percentage reduction in the Eczema Area and Severity Index score from baseline to week 52. Secondary measures included the mean percentage reduction in the Pruritus and Sleep Numerical Rating Scales and the Dermatology Life Quality Index, and the types and rates of adverse events from baseline to week 52.

RESULTS

One hundred and five patients were eligible for the study. Flexural dermatitis was the most frequent clinical phenotype (63.8%). The coexistence of more than one clinical phenotype was found in 70/105 (66.6%) patients. We observed a reduction in all disease severity scores from baseline to week 52 (p < 0.001). Adverse events were recorded in 30/105 (28.6%) patients, with conjunctivitis and injection-site reaction the most frequent.

CONCLUSIONS

In this study, dupilumab is an effective and safe treatment for the long-term management of atopic dermatitis in patients aged over 65 years.

Therapeutic New Era for Atopic Dermatitis: Part 1. Biologics

Atopic dermatitis (AD) is a chronic, inflammatory cutaneous disease driven by immune dysregulation and skin barrier dysfunction. We are currently experiencing a new era of understanding of the pathogenesis of AD and, as a consequence, a new era of innovation in therapeutics, including small molecules and biologic therapy. Recently, advances in translational research have challenged the traditional AD pathogenesis paradigm of AD being solely a Th2-dominant disease. Other immune pathways seem to play a role in the complex AD pathophysiology, although the clinical relevance of these additional immune pathway abnormalities is unclear. Type 1, type 22, and type 17 pathway activation (with related cytokines/chemokines) have been demonstrated in the skin and blood of AD patients. Type 2 (interleukin [IL]-4, IL-13), IL-31, and type 22 (IL-22) pathway cytokines are increased in AD acute lesions. IL-22 induces both an epidermal hyperplasia at the onset of acute AD and a marked increase in the terminal differentiation S100 genes. This understanding of pathogenesis corresponds to a historic increase in therapeutic development in AD. The extreme clinical heterogeneity and the chronic progression of AD establish the need for newer, safer, and more effective treatments, control the disease, and improve the quality of life of affected patients.

Real-World Experience and Laboratory Monitoring of Dupilumab in Patients with Moderate to Severe Atopic Dermatitis in a Tertiary Centre

INTRODUCTION

Dupilumab is a biologic therapy approved for treatment of moderate to severe atopic dermatitis (AD). Our objective was to assess the real-world effectiveness, safety and laboratory monitoring practices for dupilumab in a tertiary centre.

METHODS

A retrospective review of medical records of all patients receiving dupilumab between September 2017 and October 2019 was undertaken. Eczema Area and Severity Index (EASI) and Dermatology Life Quality Index (DLQI) were collected at weeks 0, 12-16 and 26-30. Data on laboratory tests undertaken for dupilumab screening and monitoring were also collected.

RESULTS

At 12-16 weeks, 58.9% and 37.3% of patients achieved ≥ EASI 75 and ≥ EASI 90, respectively (n = 156). Ninety-four patients underwent further analysis at weeks 26-30 with those achieving ≥ EASI 75 increasing from 61.7% (12-16 weeks) to 75.31%, and EASI 90 increasing from 35.8% (12-16 weeks) to 49.8%. The most common side effects were eye symptoms occurring in 43.1% of patients, with 16.3% developing conjunctivitis. The mean treatment duration was 255 days, during which an average of three sets of blood tests were performed (n = 149). Of all laboratory abnormalities recorded, 24% started after initiation of dupilumab, and 93% were classified as 'mild'. Dupilumab was not documented as causative in any of the cases, nor was treatment stopped on account of laboratory abnormalities.

CONCLUSION

Dupilumab provides an effective and safe treatment option for patients with AD. Clinical response continued to improve past 16 weeks in this real-world population. No laboratory abnormalities were felt to be secondary to dupilumab; screening and monitoring tests did not influence dupilumab prescribing.

Efficacy of dupilumab in atopic comorbidities associated with moderate-to-severe adult atopic dermatitis

BACKGROUND

Dupilumab is an anti-IL-4Rα antibody used in the treatment of patients with moderate-to-severe atopic dermatitis (msAD). This study explored the potential benefit of dupilumab in perennial allergic rhinoconjunctivitis (PAR) and perennial allergic asthma (PAA) caused by indoor allergens in adults with msAD.

METHODS

This multicentric, prospective, observational, real-life study included adult patients with msAD who had been treated with dupilumab in 16 Italian care centres. Efficacy outcomes regarding AD, PAR and PAA were collected at baseline and 16 weeks. Safety was also assessed.

RESULTS

We enrolled 123 patients with msAD. Between baseline and 16 weeks of treatment, the following measurements decreased statistically significantly: Eczema Area and Severity Index, SCOring AD, Patient-Oriented Eczema Measure, pruritus score, sleep score, Dermatology Life Quality Index and IgE. Dupilumab treatment in patients with comorbid PAR (n = 41) was associated with significant improvements in PAR disease control (measured using a Rhinitis Control Scoring System) and in PAR Quality of life (QoL) (measured using the Rhinoconjunctivitis QoL Questionnaire scores). In 32 patients with comorbid PAA, dupilumab significantly improved PAA control (measured using the Asthma Control Test and five-item Asthma Control Questionnaire scores) and disease-related QoL (measured using the Asthma QoL Questionnaire scores). Thirty-five patients (28.5%) developed conjunctivitis during the study period.

CONCLUSION

These results support the benefits of dupilumab for adult patients with PAR and/or PAA associated with msAD.

Real-world evidence of dupilumab efficacy and risk of adverse events: A systematic review and meta-analysis

BACKGROUND

Dupilumab, the first biological drug to be approved for the treatment of moderate to severe atopic dermatitis in adolescents and adults, has shown good efficacy and safety in clinical trials.

OBJECTIVE

To evaluate real-world data on the efficacy and safety of dupilumab in atopic dermatitis.

METHODS

PubMed and EMBASE were searched for observational studies with data on efficacy, drug survival, and safety of dupilumab for the treatment of atopic dermatitis. Primary outcomes were mean percentage change in Eczema Area and Severity Index (EASI) score and proportion of atopic dermatitis patients achieving 50%, 75%, and 90% improvement in EASI score after dupilumab therapy.

RESULTS

Twenty-two unique studies encompassing 3303 atopic dermatitis patients were included. After 16 weeks of dupilumab therapy, the pooled proportion of patients achieving 50%, 75%, and 90% EASI score improvement was 85.1%, 59.8%, and 26.8%, respectively, and the weighted mean reduction in EASI score was 69.6%. Conjunctivitis was the most common adverse event, reported in a pooled proportion of 26.1%.

LIMITATIONS

Limited data in terms of size and follow-up time were available.

CONCLUSION

Real-world data show that dupilumab is a successful and well-tolerated therapy for atopic dermatitis, but ocular adverse events commonly occur. Registries are needed to monitor for adverse events.

Clinical Response and Quality of Life in Patients with Severe Atopic Dermatitis Treated with Dupilumab: A Single-Center Real-Life Experience

Dupilumab is an anti-interleukin-4 receptor monoclonal antibody that was recently approved for the treatment of atopic dermatitis (AD). In this single-center retrospective study, clinical baseline data of 117 severe AD patients treated with dupilumab were collected. At baseline and at weeks 4 and 16, disease severity was assessed through the Eczema Area and Severity Index (EASI) and quality of life through the Dermatology Life Quality Index (DLQI) questionnaire, Patient-Oriented Eczema Measure (POEM), Hospital Anxiety and Depression Scale (HADS), Peak Pruritus Numerical Rating Scale (NRS-itch), and VAS-sleep. Response to dupilumab was defined as an improvement of ≥75% in EASI from baseline (EASI75). At multivariate analysis, AD onset before 18 years [OR, 2.9; 95% CI, 1.2–7.2; p = 0.0207] and absence of hypereosinophilia [OR, 2.24; 95% CI, 1.03–4.86; p = 0.0412] were identified as significant predictive parameters for response to dupilumab in terms of EASI75 at week 4 but not at week 16. Significant reductions in EASI, DLQI, POEM, HADS, NRS-itch, and VAS-sleep were found between week 4 versus baseline (p < 0.0001 for all) and week 16 versus baseline (p < 0.0001 for all). Early AD onset and absence of hypereosinophilia may be suggested as predictive markers of early response to dupilumab. We confirmed the efficacy and safety of this agent along with the improvement of life quality in severe AD patients.

Effectiveness of dupilumab treatment in 95 patients with atopic dermatitis: daily practice data

BACKGROUND

Dupilumab is the first biologic registered for the treatment of moderate-to-severe atopic dermatitis (AD), and efficacy was shown in phase III clinical trials (primary outcome at week 16 was reached in 38% of patients). Currently, there are limited daily practice data available for dupilumab, especially when it is combined with systemic immunosuppressants.

OBJECTIVES

To evaluate dupilumab treatment in daily practice in patients with AD.

METHODS

In this observational cohort study, we prospectively included all adult patients with AD who had been treated with dupilumab in two university hospitals in the Netherlands. Concomitant systemic immunosuppressive treatment was monitored. Physician-reported outcome measures and patient-reported outcome measures (PROMs) after ≥ 12 weeks of follow-up were analysed. We used a linear mixed-effects model to determine changes in scores during follow-up.

RESULTS

Ninety-five patients were included. Of these, 62 patients were using systemic immunosuppressants at baseline; the use of systemic immunosuppressants was continued during dupilumab treatment in 43 patients. From baseline to 16 weeks of treatment, the estimated mean Eczema Area and Severity Index score (0-72) decreased from 18·6 [95% confidence interval (CI) 16·0-21·4)] to 7·3 (95% CI 5·4-10·0), and the estimated mean PROMs showed a decrease of 41-66%. Investigator's Global Assessment 0 or 1 (clear/almost clear) was reached in 38% of the patients. Five patients discontinued dupilumab treatment due to side-effects or ineffectiveness. Eye symptoms and orofacial (nonocular) herpes simplex virus (HSV) reactivation were reported in 62% and 8% of the patients, respectively.

CONCLUSIONS

Dupilumab treatment in daily practice shows a clinically relevant improvement of physician-reported outcome measures and PROMs, which is in line with efficacy data from clinical trials. Besides frequently reported eye symptoms and orofacial (nonocular) HSV reactivation, there were no apparent safety concerns. What's already known about this topic? Dupilumab has been shown to be an efficacious treatment for atopic dermatitis in several clinical trials. However, it is known that there may be considerable differences in patient characteristics and treatment responses between clinical trials and daily practice. What does this study add? This study presents the first experience with dupilumab treatment in 95 patients with atopic dermatitis in daily practice in two Dutch university hospitals. Less stringent inclusion and exclusion criteria and follow-up schedules, in contrast to those used in clinical trials, might better represent daily practice. Dupilumab treatment shows a clinically relevant improvement of physician- and patient-reported outcome measures; besides patient-reported eye symptoms (in 59 of 95 patients; 62%) and an apparent increase in orofacial (nonocular) herpes simplex virus reactivation (eight of 95 patients; 8%), there were no other safety concerns during follow-up up to 16 weeks of dupilumab treatment.
