Treatment Outcomes Associated With Dupilumab Use in Patients With Atopic Dermatitis: 1-Year Results From the RELIEVE-AD Study

Practical Management of the JAK1 Inhibitor Abrocitinib for Atopic Dermatitis in Clinical Practice: Special Safety Considerations

Abrocitinib, an oral, once-daily, Janus kinase (JAK) 1-selective inhibitor, is approved for the treatment of adults and adolescents with moderate-to-severe atopic dermatitis (AD). Abrocitinib has shown rapid and sustained efficacy in phase 3 trials and a consistent, manageable safety profile in long-term studies. Rapid itch relief and skin clearance are more likely to be achieved with a 200-mg daily dose of abrocitinib than with dupilumab. All oral JAK inhibitors are associated with adverse events of special interest and laboratory changes, and initial risk assessment and follow-up monitoring are important. Appropriate selection of patients and adequate monitoring are key for the safe use of JAK inhibitors. Here, we review the practical use of abrocitinib and discuss characteristics of patients who are candidates for abrocitinib therapy. In general, abrocitinib may be used in all appropriate patients with moderate-to-severe AD in need of systemic therapy, provided there are no contraindications, e.g., in patients with active serious systemic infections and those with severe hepatic impairment, as well as pregnant or breastfeeding women. For patients aged ≥ 65 years, current long-time or past long-time smokers, and those with risk factors for venous thromboembolism, major adverse cardiovascular events, or malignancies, a meticulous benefit-risk assessment is recommended, and it is advised to start with the 100-mg dose, when abrocitinib is the selected treatment option.

Dupilumab provides sustained effectiveness on patient-reported outcomes and favorable safety in patients with moderate-to-severe atopic dermatitis: Up to 5-year results from the daily practice BioDay registry

BACKGROUND

Long-term daily practice data on patient-reported benefits of dupilumab for atopic dermatitis (AD) remains limited.

OBJECTIVE

To evaluate patient-reported outcome measures (PROMs) and the safety of dupilumab in patients with moderate-to-severe AD over a follow-up period of up to 5 years.

METHODS

Data were extracted from the prospective, multicenter BioDay registry (October 2017-2022) of patients with moderate-to-severe AD treated with dupilumab in daily practice.

RESULTS

In total 1223 patients, 1108 adults and 115 pediatric patients were included. After ≥1 year of treatment, mean Patient-Oriented Eczema Measure (POEM), Dermatology Life Quality Index (DLQI), Numeric rating scale (NRS)-pruritus ranged between 7.8 and 8.7, 3.5 and 4.2, and 2.9 and 3.1 in adults, respectively, whilst these patient-reported outcome measures (PROMs) ranged between 8.9 and 10.9, 4.4 and 6.4, and 3.0 and 3.7 in pediatric patients, respectively. At follow-up, overall work impairment decreased from 40.1% to 16.3% to 13.3% in adults. Furthermore, class I obesity and itch-dominant patients generally had less favorable treatment response. Of all patients, 66.8% reported ≥1 adverse event, with conjunctivitis being the most common (33.7%).

LIMITATIONS

The overall percentage of missing values for selected PROMs was 26% in adults and 46% in pediatric patients.

CONCLUSION

In addition to favorable safety, dupilumab has demonstrated sustained effectiveness across various PROMs, underscoring the treatment benefits from patients' perspectives.

Early and Sustained Improvements in Symptoms and Quality of Life with Upadacitinib in Adults and Adolescents with Moderate-to-Severe Atopic Dermatitis: 52-Week Results from Two Phase III Randomized Clinical Trials (Measure Up 1 and Measure Up 2)

BACKGROUND

Atopic dermatitis is a chronic inflammatory disease characterized by increased itch, skin pain, poor sleep quality, and other symptoms that negatively affect patient quality of life. Upadacitinib, an oral selective Janus kinase (JAK) inhibitor with greater inhibitory potency for JAK1 than JAK2, JAK3, or tyrosine kinase 2, is approved to treat moderate-to-severe atopic dermatitis.

OBJECTIVE

We aimed to evaluate the effect of upadacitinib on patient-reported outcomes over 52 weeks in adults and adolescents with moderate-to-severe atopic dermatitis.

METHODS

Data from two phase III monotherapy trials of upadacitinib (Measure Up 1, NCT03569293; Measure Up 2, NCT03607422) were integrated. Changes in pruritus, pain, other skin symptoms, sleep, quality of life, mental health, and patient impression were evaluated. Patient-reported outcome assessments included the Worst Pruritus Numerical Rating Scale, Patient-Oriented Eczema Measure, Dermatology Life Quality Index, Atopic Dermatitis Symptom Scale, Atopic Dermatitis Impact Scale, Hospital Anxiety and Depression Scale, SCORing Atopic Dermatitis index, Patient Global Impression of Severity, Patient Global Impression of Change, and Patient Global Impression of Treatment. Minimal clinically important differences, achievement of scores representing minimal disease burden, and the change from baseline were evaluated in patients who received upadacitinib through week 52 and in patients who received placebo through week 16.

RESULTS

This analysis included 1609 patients (upadacitinib 15 mg, N = 557; upadacitinib 30 mg, N = 567; placebo, N = 485). Baseline demographics and disease characteristics were generally similar across all arms. The proportion of patients treated with upadacitinib reporting improvements in itch increased rapidly by week 1, increased steadily through week 8, and was sustained through week 52. Patients receiving upadacitinib also experienced improvements in pain and other skin symptoms by week 1, which continued through week 16; improvements were maintained through week 52. Patient reports of improved sleep increased rapidly from baseline to week 1, increased steadily through week 32, and were sustained through week 52. Patients experienced quality-of-life improvements through week 8, which were maintained through week 52. By week 1, patients in both upadacitinib groups experienced rapid improvements in emotional state, and by week 12, patients also achieved meaningful improvements in anxiety and depression. Improvements in mental health continued steadily through week 32 and were maintained through week 52. Patients treated with upadacitinib 30 mg generally experienced improvements in patient-reported outcomes earlier than those treated with upadacitinib 15 mg. Through week 16, patients receiving upadacitinib experienced greater improvements versus those receiving placebo in all assessed patient-reported outcomes.

CONCLUSIONS

Adults and adolescents with moderate-to-severe atopic dermatitis treated with once-daily upadacitinib 15 or 30 mg experienced early improvements in itch, pain, other skin symptoms, sleep, quality of life, and mental health that were sustained through week 52.

How to use the Harmonising Outcome Measures for Eczema Core Outcome Set for atopic dermatitis trials: a users' guide

BACKGROUND

The Harmonising Outcome Measures for Eczema (HOME) initiative has agreed upon the Core Outcome Set (COS) for use in atopic dermatitis (AD) clinical trials, but additional guidance is needed to maximize its uptake.

OBJECTIVES

To provide answers to some of the commonly asked questions about using the HOME COS; to provide data to help with the interpretation of trial results; and to support sample size calculations for future trials.

METHODS AND RESULTS

We provide practical guidance on the use of the HOME COS for investigators planning clinical trials in patients with AD. It answers some of the common questions about using the HOME COS, how to access the outcome measurement instruments, what training/resources are needed to use them appropriately and clarifies when the COS is applicable. We also provide exemplar data to inform sample size calculations for eczema trials and encourage standardized data collection and reporting of the COS.

CONCLUSIONS

By encouraging adoption of the COS and facilitating consistent reporting of outcome data, it is hoped that the results of eczema trials will be more comprehensive and readily combined in meta-analyses and that patient care will subsequently be improved.

Long-Term Effectiveness of Dupilumab in Patients with Atopic Dermatitis: Results up to 3 Years from the RELIEVE-AD Study

INTRODUCTION

Atopic dermatitis (AD) can require long-term therapy. Few real-world studies have evaluated long-term effectiveness from the patients' perspective. The aim of this study was to evaluate patient-reported outcomes (PROs) during long-term dupilumab treatment.

METHODS

Adults with moderate-to-severe AD who initiated dupilumab through the US manufacturer patient support program and participated in RELIEVE-AD (a prospective patient survey study with a 12-month follow-up) were recontacted 30-36 months post-initiation regardless of current dupilumab use. The online questionnaire consisted of PROs, including the Atopic Dermatitis Control Tool (ADCT), use of concomitant AD therapies, satisfaction with current therapy, global change in itch relative to before dupilumab initiation, non-itch skin symptoms (skin pain/soreness, hot/burning feeling, and sensitivity to touch), flares, Dermatology Life Quality Index, sleep problems, and the AD-specific Work Productivity and Activity Impairment Questionnaire.

RESULTS

Of 698 patients who initiated dupilumab (baseline) and were recontacted, 425 completed the 30-36-month survey. Significant reductions from baseline were reported in concomitant AD therapy use (P < 0.05); 54.4% reported not using other AD medications vs. 12.8% at baseline. At 30-36 months, all results (non-itch skin symptoms, flares, sleep problems, health-related quality of life work/activity impairment, disease control, and treatment satisfaction) were similar to or incrementally better than the 12-month timepoint, with significant improvements vs. baseline (P < 0.001). Global change in itch was reported as "very much better" by 75.3% of respondents. Adequate disease control (score < 7 on ADCT) was reported by 80.7% of respondents, and 86.8% were satisfied with the treatment.

CONCLUSIONS

In clinical practice settings, patient-reported benefits of dupilumab were maintained in survey respondents during long-term treatment up to 36 months while the use of concomitant AD therapies reduced.

Dupilumab Demonstrates Rapid Onset of Action in Improving Signs, Symptoms and Quality of Life in Adults with Atopic Dermatitis

INTRODUCTION

Dupilumab has significantly improved the signs, symptoms and quality of life (QoL) of patients with moderate-to-severe atopic dermatitis (AD) in randomised, controlled clinical trials. However, there is a need to assess the effectiveness and safety of dupilumab in real-world clinical practice. The PROLEAD study was designed to examine the effectiveness and safety of dupilumab in moderate-to-severe AD in a real-world setting in Germany. Here, we present 12-week effectiveness and safety results with dupilumab from PROLEAD.

METHODS

PROLEAD is a multicentre, prospective, non-interventional study being conducted at 126 routine care sites across Germany. Adults with moderate-to-severe AD who require systemic therapy were treated with dupilumab as indicated by the Summary of Product Characteristics. Data collected included physician assessments (EASI, BSA, SCORAD, and IGA) and patient-reported outcomes (PROs [POEM, DLQI, EQ-5D-5L, Peak Pruritus NRS and MOS Sleep Scale]).

RESULTS

Of 839 patients assessed for eligibility, 828 were included. The full analysis and safety analysis sets comprised 775 and 818 patients, respectively. The number of patients receiving concomitant therapy decreased from baseline to Week 12. Mean (standard deviation [SD]) percentage change in EASI score from baseline to Week 12 was -67.5% (48.4%) and was comparable across the four body regions. The proportion of patients achieving EASI-75 was 59.4% at Week 12. Mean (SD) Peak Pruritus NRS decreased from 7.4 (2.3) at baseline to 3.4 (2.6) at Week 12. Improvements from baseline to Week 12 were reported in all PROs assessed. No new safety signals were observed.

DISCUSSION

Improvements in efficacy outcomes and adverse event rates in a real-world setting were more favourable than in phase 3 clinical trials.

CONCLUSIONS

The 12-week findings of PROLEAD demonstrate that treatment with dupilumab is effective and well tolerated, with rapid onset of action in signs, symptoms and QoL in patients with moderate-to-severe AD in the real world.

Experiences from daily practice of upadacitinib treatment on atopic dermatitis with a focus on hand eczema: Results from the BioDay registry

BACKGROUND

Real-world data on the effectiveness of upadacitinib on atopic dermatitis (AD), hand eczema (HE) and HE in the context of AD are limited.

OBJECTIVES

To evaluate the effectiveness and safety of upadacitinib on AD and on HE in patients with AD.

METHODS

This prospective observational cohort study includes clinical outcomes: Eczema Area and Severity Index (EASI), Investigator's Global Assessment (IGA), Hand Eczema Severity Index (HECSI), Photographic guide; and PROMs: average pruritus and pain Numeric Rating Scale (NRS) score of the past week, Patient-Oriented Eczema Measure (POEM), Patient-Oriented Eczema, Dermatology Life Quality Index (DLQI), Atopic Dermatitis Control Tool (ADCT), Patient Global Assessment of Disease (PGAD), Quality Of Life Hand Eczema Questionnaire (QOLHEQ) at baseline, Week 4, and Week 16 of upadacitinib-treated patients. Adverse events were monitored during each visit.

RESULTS

Thirty-eight patients were included, of which 32 patients had HE. At Week 16, EASI-75 was achieved by 50.0%. Absolute cutoff score NRS-pruritus ≤4 was reached by 62.5%, POEM ≤7 by 37.5%, DLQI ≤5 by 59.4%, ADCT <7 by 68.8%, and PGAD rating of at least 'good' by 53.1%. HECSI-75 was achieved by 59.3% and (almost) clear on the Photographic guide by 74.1%. The minimally important change in QOLHEQ was achieved by 57.9%. Sub-analysis in patients with concomitant irritant contact dermatitis showed no differences. Safety analysis showed no new findings compared to clinical trials.

CONCLUSIONS

Upadacitinib can be an effective treatment for patients with AD and concomitant HE in daily practice. Future studies should focus on the effectiveness of upadacitinib on chronic HE, especially on the different etiological subtypes of HE, including HE in non-atopic individuals.

Insights into atopic dermatitis pathogenesis lead to newly approved systemic therapies

Atopic dermatitis (AD) is a common inflammatory skin disease characterized by scaly, oozing skin and itch. In moderate-to-severe AD, treatment options have been historically very limited and off-label use has been a common method for disease management. For decades, ciclosporin A was the only systemic immunosuppressive drug approved in most European countries to address this major unmet medical need. However, increased understanding of the pathophysiology of AD has led to a revolution in the treatment of this potentially debilitating disease. Following the approval of the first biological therapy for AD in 2017, there has been a rapid expansion of compounds under development and four additional systemic therapies have been approved in Europe and the USA within the past 3 years alone. In this review, we underscore how key breakthroughs have transformed the therapeutic landscape of AD, leading to a major expansion of type 2 immunity-targeted biological therapies, exploration of neuroimmune modulatory agents, and interest in Janus kinase inhibition.

The clinical significance of dupilumab-induced blood eosinophil elevation in Japanese patients with atopic dermatitis

This study aims to clarify the clinical significance of dupilumab-induced elevation of blood eosinophil in Japanese patients with atopic dermatitis (AD). Eosinophil elevation was defined as ≥ 5% increase of eosinophil percentage within one year after dupilumab initiation. Seven patients (15.7%) were shown to have eosinophil elevation, six of whom developed dupilumab-associated conjunctivitis (DAC) and were accompanied with DAC more frequently than those without eosinophil elevation, with statistically significant difference. Eosinophil percentage resolved spontaneously in all seven patients, including the one without DAC, despite the continuation of dupilumab treatment. None of the patients with eosinophil elevation had cardiac or pulmonary complications attributable to the hypereosinophilia. The patients with eosinophil elevation were all male. Furthermore, none of four patients in whom efficacy of dupilumab was < 25% showed eosinophil elevation. Childhood onset tended to be more common in patients with the elevation of eosinophil. This study suggests that most eosinophil elevation is associated with DAC, and that the eosinophil ratio is a biomarker for DAC.
