Targeted Combined Endpoint Improvement in Patient and Disease Domains in Atopic Dermatitis: A Treat-to-Target Analysis of Adults with Moderate-to-Severe Atopic Dermatitis Treated with Upadacitinib.

A treat-to-target approach was recently developed to guide systemic treatment for adults with atopic dermatitis (AD). Recommendations outlined criteria for a 3-month initial acceptable treatment target and a 6-month optimal target, evaluated using global assessment of patient-reported disease severity, as well as Eczema Area and Severity Index, itch assessed on an 11-point numerical rating scale, Dermatology Life Quality Index, or Patient-Oriented Eczema Measure. Achievement of these targets with once-daily upadacitinib (15 mg and 30 mg) monotherapy was evaluated using integrated adult data from the Measure Up 1 and 2 phase 3 studies. Among the 852 patients treated with upadacitinib 15 mg or 30 mg, the 3-month initial acceptable target was achieved by >80%, >78%, and ≥87% of patients, and the 6-month optimal target was achieved by ≥53%, >61%, and >73% of patients at weeks 2, 16, and 52, respectively. Achievement of all 6 individual criteria for each of the target goals also increased over time. These findings suggest that upadacitinib 15 mg and 30 mg may help improve standards of care in patients with moderate-to-severe AD by achieving 6-month target goals at 16 weeks and as early as 2 weeks for most patients.

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. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov identifiers NCT03569293 (13 August 2018) and NCT03607422 (27 July 2018).

Atopic dermatitis, or eczema, is a condition that causes painful itchy dry skin, which is burdensome for patients and has a negative impact on quality of life. These symptoms frequently lead to disruption of daily activities such as school and work, decreased self-confidence, social isolation, anxiety, depression, and sleep disturbance. Symptoms of atopic dermatitis, such as itch and sleep disturbance, can only be assessed by patients. Therefore, it is important to consider patients' perceptions of their symptoms and the related impact on their quality of life, especially when evaluating treatment benefits. Upadacitinib is an orally administered drug approved to treat moderate-to-severe atopic dermatitis. In two clinical trials (Measure Up 1 and Measure Up 2), we investigated how treatment with upadacitinib (15-mg or 30-mg dose) given once daily to adults and adolescents with moderate-to-severe atopic dermatitis would impact their symptoms and quality of life over a 1-year period. We measured changes over time in patients' assessments of itch, pain, other skin-related symptoms, sleep, daily activities, emotional state, mental health, and overall quality of life. Patients treated with upadacitinib experienced improvements in symptoms of atopic dermatitis and quality of life within the first 1­2 weeks of treatment. These improvements continued to steadily increase in the following weeks and lasted through 1 year of treatment. In conclusion, once-daily treatment with upadacitinib 15 or 30 mg led to early and lasting improvements in the well-being of patients with atopic dermatitis.

Immunosuppressive and immunomodulating therapy for atopic dermatitis in pregnancy: an appraisal of the literature.

Atopic dermatitis (AD) is the most common dermatological diagnosis during pregnancy. Treatment of AD during pregnancy can be challenging, due to the unpredictable course and the fact that the therapy needs to be safe for both the mother and the fetus. Here we present an up-to-date appraisal of the literature on the treatment options available for AD in patients planning pregnancy, during pregnancy, and during breastfeeding. All patients with AD are recommended to supplement any medical treatment with daily applications of emollients. The first step in the medical treatment for AD during pregnancy are topical corticosteroids, and/or topical tacrolimus. If required, UV-light therapy can also be considered. Treatment with systemic therapy during pregnancy should always rely on a careful risk-benefit assessment and be based on shared-decision making between the treating physician and patient. The first-line systemic treatment option is cyclosporine A, whereas azathioprine may be considered in patients already receiving this treatment prior to pregnancy. Systemic glucocorticoids may also be used. Treatment with systemic JAK inhibitors is not recommended, whereas treatment with mycophenolate mofetil and methotrexate is contraindicated. Targeted therapy with dupilumab is not generally recommended, due to lack of experience in human pregnancies, yet some case-reports on their use are emerging. These recommendations are based on the authors appraisal of existing literature and the current recommendation from the European Task Force on Atopic Dermatitis. It is always the responsibility of the treating physician to stay updated on the newest guidelines and literature when treating patients with AD during pregnancy.

Treat-to-Target in Atopic Dermatitis.

Atopic dermatitis is one of the most common inflammatory skin diseases among children and adults. Over the last 5 years, the armamentarium for the treatment of this disease, with both topical and systemic drugs, has increased. Treat-to-target is basically the concept where a treatment goal and a time frame for that goal is set at initiation of a new treatment, and if the goals are not achieved in time, treatment will be adjusted. In clinical trials, treatment targets are based on scoring systems for disease severity as recommended by the Harmonizing Outcome Measure for Eczema (HOME) initiative, with the primary endpoint being a reduction of at least 75% of the baseline Eczema Area and Severity Index (EASI) score (EASI-75). The question, however, is if these are useful targets in real-world settings and how this should be implemented in everyday clinical practice. In rheumatology, setting a measurable target and a time frame for an instigated therapy has been shown to lead to more efficient and successful treatment. For atopic dermatitis, the instruments recommended by HOME form the core outcome measures for the treat-to-target frameworks published to date, which are based on expert consensus and Delphi processes. Although atopic dermatitis patients have a high risk of co-morbidities, including physical, psychological and socioeconomic, instruments to measure the severity of co-morbidities have not been included in these existing frameworks. In order to apply a treat-to-target strategy that is meaningful for both the patient and the doctor, validated tools for the measurement of treatment effect on co-morbidities exist and should be included in a shared decision-making process with the individual patient when choosing which targets to aim for and what should be considered treatment success. An obvious limitation for the implementation of a treat-to-target strategy in the clinical setting with atopic dermatitis is that retrieving the data needed is very time consuming. This could to some degree be mitigated by the use of electronic applications in which patients could report their outcomes.

Interpreting the Relationship Among Itch, Sleep, and Work Productivity in Patients with Moderate-to-Severe Atopic Dermatitis: A Post Hoc Analysis of JADE MONO-2.

BACKGROUND: Abrocitinib, an oral, once-daily Janus kinase 1-selective inhibitor, improved itch severity, sleep, and work productivity versus placebo in patients with moderate-to-severe atopic dermatitis. OBJECTIVE: The aim of this study was to investigate relationships among itch, sleep, and work productivity in the phase III JADE MONO-2 clinical trial. METHODS: A repeated-measures longitudinal model was used to examine relationships between itch (using the Peak Pruritus Numerical Rating Scale [PP-NRS] or Nighttime Itch Scale [NTIS]) and sleep disturbance/loss (using the Patient-Oriented Eczema Measure sleep item and SCORing AD Sleep Loss Visual Analog Scale) and, separately, between itch and work productivity (using the Work Productivity and Activity Impairment-Atopic Dermatitis Version 2.0 questionnaire). Mediation modelling was used to investigate the effect of treatment (abrocitinib vs placebo) on work impairment via improvements in itch and sleep. RESULTS: The relationships between itch/sleep and itch/work productivity were approximately linear. PP-NRS scores of 0, 4-6, and 10 were associated with 0 days, 3-4 days, and 7 days per week of disturbed sleep, respectively. PP-NRS or NTIS scores of 0-1, 4-5, and 10 were associated with 0-10%, 20-30%, and >50% overall work impairment, respectively. Seventy-five percent of the effect of abrocitinib on reducing work impairment was indirectly mediated by improvement in itch, followed by sleep. CONCLUSION: These results quantitatively demonstrate that reducing itch severity is associated with improvements in sleep and work productivity. Empirical evidence for the mechanism of action of abrocitinib showed that itch severity is improved, which reduces sleep loss/sleep disruption and, in turn, improves work productivity. CLINICAL TRIAL REGISTRATION: NCT03575871.

Atopic dermatitis (AD), also called atopic eczema, is a common skin disease that is associated with itch and reduced quality of life. Abrocitinib, a recently approved medicine for AD, was shown in clinical trials to improve itch, which is considered the most bothersome symptom to people with AD. Abrocitinib also improved sleep outcomes and work productivity in people with moderate or severe AD. It is unknown if improvement in itch can lead to improvement in sleep and work productivity. We analyzed data from the JADE MONO-2 study, which included 391 people who received treatment with abrocitinib or placebo for 12 weeks. We used mathematical modelling to study relationships between itch and sleep or work productivity. We also wanted to study if the improvements in itch and sleep with abrocitinib treatment had an impact on work productivity. We found that a relationship existed between itch, sleep disturbance, and work impairment; as itch improved, so too did sleep disturbance and work impairment. When people were treated with abrocitinib, they experienced relief from itch, which improved sleep, which in turn reduced work productivity loss. Larger and longer studies are needed to confirm these results. This analysis further informs the expectations of patients with moderate or severe AD as it relates to progression of symptom relief after treatment with abrocitinib.

A concept for integrated care pathways for atopic dermatitis-A GA2 LEN ADCARE initiative.

INTRODUCTION: The integrated care pathways for atopic dermatitis (AD-ICPs) aim to bridge the gap between existing AD treatment evidence-based guidelines and expert opinion based on daily practice by offering a structured multidisciplinary plan for patient management of AD. ICPs have the potential to enhance guideline recommendations by combining interventions and aspects from different guidelines, integrating quality assurance, and describing co-ordination of care. Most importantly, patients can enter the ICPs at any level depending on AD severity, resources available in their country, and economic factors such as differences in insurance reimbursement systems. METHODS: The GA2 LEN ADCARE network and partners as well as all stakeholders, abbreviated as the AD-ICPs working group, were involved in the discussion and preparation of the AD ICPs during a series of subgroup workshops and meetings in years 2020 and 2021, after which the document was circulated within all GAL2 EN ADCARE centres. RESULTS: The AD-ICPs outline the diagnostic procedures, possible co-morbidities, different available treatment options including differential approaches for the pediatric population, and the role of the pharmacists and other stakeholders, as well as remaining unmet needs in the management of AD. CONCLUSION: The AD-ICPs provide a multidisciplinary plan for improved diagnosis, treatment, and patient feedback in AD management, as well as addressing critical unmet needs, including improved access to care, training specialists, implementation of educational programs, assessment on the impact of climate change, and fostering a personalised treatment approach. By focusing on these key areas, the initiative aims to pave the way for a brighter future in the management of AD.

Abrocitinib efficacy and safety in patients with moderate-to-severe atopic dermatitis: Results from phase 3 studies, including the long-term extension JADE EXTEND study.

BACKGROUND: Abrocitinib improved signs and symptoms of moderate-to-severe atopic dermatitis (AD) at 12 or 16 weeks in phase 3 studies with a manageable safety profile. Further understanding of the abrocitinib long-term efficacy and safety profile is important for its appropriate use in treating chronic AD. OBJECTIVE: To evaluate the abrocitinib efficacy up to 48 weeks and long-term safety in patients with moderate-to-severe AD. METHODS: JADE EXTEND (NCT03422822) is an ongoing, phase 3, long-term extension study that enrolled patients from previous abrocitinib AD trials. This analysis focusses on patients from the phase 3 JADE MONO-1 (NCT03349060), JADE MONO-2 (NCT03575871) and JADE COMPARE (NCT03720470) studies who completed the full treatment period of placebo or abrocitinib (200 mg or 100 mg once daily) and subsequently entered JADE EXTEND. Efficacy endpoints included the proportion of patients achieving skin clearance (Investigator's Global Assessment [IGA] 0/1 [clear/almost clear]; ≥75% improvement in Eczema Area and Severity Index [EASI-75]) and itch response (Peak Pruritus Numerical Rating Scale [PP-NRS] severity ≥4-point improvement). Safety endpoints included treatment-emergent adverse events (TEAEs), serious TEAEs and TEAEs leading to discontinuation. Data cut-off: April 22, 2020. RESULTS: As of the data cut-off, ~70% and ~45% of patients received abrocitinib for ≥36 and ≥48 weeks, respectively. Nasopharyngitis, atopic dermatitis, nausea and upper respiratory tract infections were the most frequent TEAEs. Serious TEAEs occurred in 7% and 5% and TEAEs leading to study discontinuation occurred in 9% and 7% of patients receiving abrocitinib 200 mg and 100 mg, respectively. Week 48 efficacy responses with abrocitinib 200 mg and 100 mg were as follows: IGA 0/1 52% and 39%; EASI-75 82% and 67%, and PP-NRS severity ≥4-point improvement 68% and 51%. CONCLUSIONS: In patients with moderate-to-severe AD, long-term abrocitinib treatment resulted in clinically meaningful skin and pruritus improvement. The long-term safety profile was manageable and consistent with previous reports.

The Treat-to-Target Project in Atopic Dermatitis: One Year On.

Atopic dermatitis is a chronic skin condition for which a range of systemic treatments have recently been approved. A treat-to-target strategy has been developed previously alongside an algorithm to guide the management of patients with atopic dermatitis. Here, we review the strategy and algorithm in the context of the evolving therapeutic landscape, and identify areas for further refinement and development.

A nationwide 104 weeks real-world study of dupilumab in adults with atopic dermatitis: Ineffectiveness in head-and-neck dermatitis.

BACKGROUND: Evaluation of effectiveness and safety of new systemic treatments for atopic dermatitis (AD) after approval is important. There are few published data exceeding 52-week therapy with dupilumab. OBJECTIVES: To examine the safety, effectiveness and drug survival of dupilumab in a Danish nationwide cohort with moderate-to-severe AD up to 104 weeks exposure. METHODS: We included 347 adult patients with AD who were treated with dupilumab and registered in the SCRATCH registry during 2017-2022. RESULTS: At all visits, we observed improvement in AD severity measured by Eczema Area and Severity Index (EASI) [median (IQR)]. EASI score at baseline was 18.0 (10.6-25.2), at week 4: 6.5 (3.5-11.6), at week 16: 3.7 (1.2-6.2), at week 52: 2.0 (0.8-3.6), at week 104: 1.7 (0.8-3.8). While drug survival was high (week 52: 90%; week 104: 86%), AD in the head-and-neck area remained present in most patients at high levels; proportion with head-and-neck AD at baseline was 76% and 68% at week 104. 35% of patients reported any AE. Conjunctivitis was the most frequent (25% of all patients) and median time to first registration of conjunctivitis was 201 days. CONCLUSIONS: While 2-year drug survival was 86%, dupilumab was unable to effectively treat AD in the head-and-neck area, and conjunctivitis was found in 25% of patients.

The impact of home treatment and self-administration of omalizumab on chronic urticaria.

Background: Patients suffering from Chronic Spontaneous Urticaria (CSU) may be recalcitrant to treatment with high dose second-generation antihistamines. These patients are, according to international guidelines, eligible to treatment with omalizumab. Treatment with omalizumab has proven to be very effective for this group of patients. Until 2018, when the self-administration of omalizumab was approved, patients have had to visit an outpatient clinic to receive the treatment. Methods: In this study we performed a survey among 75 CSU patients who had changed their treatment from administration at an outpatient clinic to self-administration at home. Results: None of the patients experienced decreased effect of the treatment with omalizumab, whereas 41.4% reported improved effect of the treatment during self-administration.The most common reported benefits for the patients were decreased travel time and the ability to choose dosing time at the day of treatment, whereas the most reported concern was fear of performing the injection. Conclusions: Patients are very content with self-administration of omalizumab. There has been no decreased effect of the treatment, and as discussed in this paper, there might be other societal benefits from self-administration. Thus, self-administration at home of omalizumab should be standard of care when using this treatment.

T-cell immunoglobulin and mucin domain 3 is upregulated in rheumatoid arthritis, but insufficient in controlling inflammation.

OBJECTIVES: Rheumatoid arthritis (RA) is a chronic autoimmune disease, that involves both pro- and anti-inflammatory mechanisms. The purpose of the present study is to investigate T-cell immunoglobulin and mucin domain 3 (Tim-3) in RA. METHODS: Plasma levels of soluble (s) Tim-3 in early RA (n=98), were followed, to evaluate association with treatment and disease activity, acquired from a prospective collected biobank (clinicaltrials.gov (NCT00660647)). We also investigate the influence of Tim-3 on spontaneous cytokine production in synovial fluid mononuclear cells (SFMC) from RA patients after addition of neutralizing anti-Tim-3's antibodies, either alone or in combination with neutralizing anti-Programmed Cell death protein 1 (PD-1) antibodies. RESULTS: Long-time stimulated CD4 T-cells expressed high levels of Tim-3, but tended to decrease their PD-1 expression. Tim-3 expression was exclusively seen co-expressed with PD-1 by CD3, CD4, CD45RO positive cells in the inflamed RA joint. Addition of neutralizing Tim-3 antibodies increased the secretion of IFNγ and MCP-1, in SFMC cultures from RA. Whereas neutralizing anti-PD-1 antibodies showed a broader impact on cytokine production. Finally, we observed that soluble Tim-3 is increased in plasma and is associated with disease activity in early RA. CONCLUSION: Taken together, our findings indicate disease-suppressive functions of Tim-3 in RA.

Severe and ChRonic Atopic dermatitis Treatment CoHort (SCRATCH): A Danish Real-world Evidence Atopic Dermatitis Treatment Registry.

Data from real-world use of new systemic treatments in atopic dermatitis (AD) is important for assessing safety and efficacy. The aim of this study is to describe the baseline characteristics of adult patients with moderate-to-severe AD enrolled in the Danish nationwide Severe and ChRonic Atopic dermatitis Treatment CoHort (SCRATCH) database, between October 2017 and August 2021. A total of 282 adult patients were included. Most (62%) were men, the median age at baseline was 43 years (interquartile range (IQR) 29-54 years), and median age at onset of AD was 1 year (IQR 0-6 years). The median Eczema Area and Severity Index at treatment initiation was 19.1 (IQR 11.9-25.7); median Patient Oriented Eczema Measure 21.0 (IQR 16.0-25.0); median Dermatology Life Quality Index 13.0 (IQR 7.0-19.0); and median itch and sleep numerical rating scale scores 8.0 (IQR 6.0-9.0) and 6.0 (IQR 4.0-8.0). Differences were found between the sexes. This registry will provide a source for future efficacy and safety studies.

Dupilumab Provides Acceptable Safety and Sustained Efficacy for up to 4 Years in an Open-Label Study of Adults with Moderate-to-Severe Atopic Dermatitis.

BACKGROUND: Moderate-to-severe atopic dermatitis (AD) often requires long-term management with systemic therapies. OBJECTIVE: Our objective was to report the safety and efficacy of dupilumab treatment up to 4 years in adults with moderate-to-severe AD and efficacy in a subgroup of patients who transitioned from dupilumab once-weekly (qw) to administration every other week (q2w). METHODS: This interim analysis of the open-label extension study (NCT01949311) evaluated dupilumab 300 mg qw or q2w in adults previously enrolled in dupilumab trials for moderate-to-severe AD. Patients switched from qw to q2w following protocol amendment. The primary outcome was safety; efficacy was also assessed. RESULTS: Of 2677 patients enrolled and treated, 352 (13.1%) completed week 204 (end of efficacy assessments) and 202 (7.5%) completed safety follow-up through week 244. Self-reported compliance was 98.1%. Dupilumab's safety profile was consistent with previous reports. Common treatment-emergent adverse events (≥5%) included nasopharyngitis, AD, upper respiratory tract infection, oral herpes, conjunctivitis, injection-site reaction, and headache. At week 204, mean ± standard deviation (SD) Eczema Area and Severity Index was 2.46 ± 3.98, and mean percent change from parent study baseline (PSBL) was -91.07%; mean ± SD Pruritus Numerical Rating Scale score was 2.10 ± 1.83, and mean percent change from PSBL was -68.74%. Efficacy was maintained in patients (n = 226) who transitioned from qw to q2w dosing. Limitations of this study included its open-label design, the lack of control arm, and smaller subsets of patients at later timepoints and receiving the approved q2w regimen. CONCLUSION: These results support dupilumab as continuous long-term treatment for adults with moderate-to-severe AD; efficacy was sustained following transition from qw to q2w dosing. TRIAL REGISTRATION CLINICALTRIALS.GOV: NCT01949311.

Atopic dermatitis is a chronic skin disease associated with inflamed skin and intense itching. People with moderate-to-severe atopic dermatitis often need long-term treatment, but many available treatments do not have demonstrated long-term safety data. In multiple clinical trials, dupilumab treatment resulted in significant improvements in signs and symptoms of atopic dermatitis. This study examined the safety and efficacy of up to 4 years of dupilumab treatment in adults with moderate-to-severe atopic dermatitis, and whether dupilumab continued to be effective in patients who switched from receiving treatment each week to treatment every other week. To address these questions, we collected data from adults who received 300 milligrams of dupilumab every week or every other week. In this study, safety findings were consistent with the known dupilumab safety profile. Patients' signs and symptoms were evaluated before and during treatment with evaluation tools including the Eczema Area and Severity Index (EASI), which indicates the extent and severity of disease, and the Pruritus Numerical Rating Scale (NRS), which indicates the intensity of itching. Reductions of 91% in EASI scores and 69% in Pruritus NRS scores showed that the improvement in signs and symptoms persisted for 204 weeks (almost 4 years) of treatment, and these effects were sustained following the switch from weekly treatment to the approved every other week treatment with dupilumab. The safety and efficacy data presented here support the use of dupilumab as a continuous, long-term treatment for up to 4 years for adults with moderate-to-severe atopic dermatitis.

Phase 3 efficacy and safety of abrocitinib in adults with moderate-to-severe atopic dermatitis after switching from dupilumab (JADE EXTEND).

BACKGROUND: Abrocitinib efficacy by prior dupilumab response status in patients with moderate-to-severe atopic dermatitis has not previously been assessed in phase 3 studies. OBJECTIVE: Examine efficacy and safety of abrocitinib among patients who received prior dupilumab. METHODS: Patients with moderate-to-severe atopic dermatitis received abrocitinib 200 mg or 100 mg once daily in JADE EXTEND (phase 3 extension) after dupilumab in double-blind, placebo-controlled phase 3 JADE COMPARE. RESULTS: Among prior dupilumab responders, ≥75% improvement in Eczema Area and Severity Index was achieved in 93.5% and 90.2% of patients who received 12 weeks of abrocitinib 200 mg and 100 mg, respectively; ≥4-point improvement in Peak Pruritus Numerical Rating Scale was achieved in 89.7% and 81.6%, respectively. Among prior dupilumab nonresponders, ≥75% improvement in Eczema Area and Severity Index was achieved with abrocitinib 200 mg and 100 mg in 80.0% and 67.7% and ≥4-point improvement in Peak Pruritus Numerical Rating Scale in 77.3% and 37.8%, respectively. Most common adverse events among abrocitinib-treated patients were nasopharyngitis, nausea, acne, and headache. Conjunctivitis occurred less frequently with abrocitinib in comparison to prior dupilumab. LIMITATIONS: Short-term, 12-week analysis; no placebo arm. CONCLUSION: Efficacy and safety profile of abrocitinib in JADE EXTEND supports the role of abrocitinib as a treatment for patients with moderate-to-severe atopic dermatitis, regardless of prior dupilumab response status.

Non-Atopic Chronic Nodular Prurigo (Prurigo Nodularis Hyde): A Systematic Review of Best-Evidenced Treatment Options.

BACKGROUND: Chronic nodular prurigo (CNPG) is a chronic, inflammatory skin disease, characterized by intense and debilitating pruritus. The pathophysiology is not fully understood, and the condition is difficult to treat with no targeted therapies. The aim of this systematic review was to review the evidence of therapies for non-atopic CNPG and conduct a meta-analysis of the results. SUMMARY: We conducted a systematic review of the literature concerning effect of treatment for non-atopic CNPG. Due to few randomized controlled trials (RCTs) and case series, the literature was unfortunately too sparse to conduct a meta-analysis of the results. Instead, we thoroughly report important data from the three existing RCTs and 6 case studies with more than 15 patients. Evaluated therapies include nemolizumab, aprepitant, topical therapy with hydrocortisone and pimecrolimus, thalidomide, UVA phototherapy, pregabalin, and naltrexone. Included RCTs and case studies all had a heterogeneous methodology making direct comparison almost impossible. KEY MESSAGES: There is sparse evidence for the currently used therapies for non-atopic CNPG. Several RCTs on new therapies are running or in the pipeline, hopefully providing new, effective, and targeted treatment possibilities for CNPG patients both with and without an atopic predisposition.
