Kołkowski K, Trzeciak M, Sokołowska-Wojdyło M. Safety and Danger Considerations of Novel Treatments for Atopic Dermatitis in Context of Primary Cutaneous Lymphomas. Int J Mol Sci 2021; 22:13388. [PMID: 34948183 PMCID: PMC8703592 DOI: 10.3390/ijms222413388] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2021] [Revised: 12/05/2021] [Accepted: 12/06/2021] [Indexed: 12/24/2022] Open
Abstract
The impact of new and emerging therapies on the microenvironment of primary cutaneous lymphomas (PCLs) has been recently raised in the literature. Concomitantly, novel treatments are already used or registered (dupilumab, upadacitinib) and others seem to be added to the armamentarium against atopic dermatitis. Our aim was to review the literature on interleukins 4, 13, 22, and 31, and JAK/STAT pathways in PCLs to elucidate the safety of using biologics (dupilumab, tralokinumab, fezakinumab, nemolizumab) and small molecule inhibitors (upadacitinib, baricitinib, abrocitinib, ruxolitinib, tofacitinib) in the treatment of atopic dermatitis. We summarized the current state of knowledge on this topic based on the search of the PubMed database and related references published before 21 October 2021. Our analysis suggests that some of the mentioned agents (dupilumab, ruxolitinib) and others may have a direct impact on the progression of cutaneous lymphomas. This issue requires further study and meticulous monitoring of patients receiving these drugs to ensure their safety, especially in light of the FDA warning on tofacitinib. In conclusion, in the case of the rapid progression of atopic dermatitis/eczema, especially in patients older than 40 years old, there is a necessity to perform a biopsy followed by a very careful pathological examination.

Abstract
The discovery of cytokines and their role in immune and inflammatory disease led to the development of a plethora of targeted biologic therapies. Later, efforts to understand mechanisms of cytokine signal transduction led to the discovery of JAKs, which themselves were quickly identified as therapeutic targets. It has been a decade since the first JAK inhibitors (jakinibs) were approved, and there are now 9 jakinibs approved for the treatment of rheumatic, dermatologic, hematologic, and gastrointestinal indications, along with emergency authorization for COVID-19. In this review, we will summarize relevant discoveries that led to first-generation jakinibs and review their efficacy and safety as demonstrated in pivotal clinical studies. We will discuss the next generation of more selective jakinibs, along with agents that target kinase families beyond JAKs. Finally, we will reflect on both the opportunities and challenges ahead as we enter the second decade of the clinical use of jakinibs.

Abstract
Introduction Pruritus is a common symptom across various dermatologic conditions, with a negative impact on quality of life. Devices to quantify itch objectively primarily use scratch as a proxy. This review compares and evaluates the performance of technologies aimed at objectively measuring scratch behavior. Methods Articles identified from literature searches performed in October 2020 were reviewed and those that did not report a primary statistical performance measure (eg, sensitivity, specificity) were excluded. The articles were independently reviewed by 2 authors. Results The literature search resulted in 6231 articles, of which 24 met eligibility criteria. Studies were categorized by technology, with actigraphy being the most studied (n = 21). Wrist actigraphy's performance is poorer in pruritic patients and inherently limited in finger-dominant scratch detection. It has moderate correlations with objective measures (Eczema and Area Severity Index/Investigator's Global Assessment: rs(ρ) = 0.70-0.76), but correlations with subjective measures are poor (r2 = 0.06, rs(ρ) = 0.18-0.40 for itch measured using a visual analog scale). This may be due to varied subjective perception of itch or actigraphy's underestimation of scratch. Conclusion Actigraphy's large variability in performance and limited understanding of its specificity for scratch merits larger studies looking at validation of data analysis algorithms and device performance, particularly within target patient populations.

Abstract
Abrocitinib (Cibinqo®) is an oral small-molecule inhibitor of Janus kinase 1 (JAK1) being developed by Pfizer for the treatment of moderate-to-severe atopic dermatitis (AD). In September 2021, abrocitinib was approved in the UK and Japan for the treatment of moderate-to-severe AD in adults and adolescents 12 years and older who are candidates for systemic therapy. Abrocitinib has also received a positive CHMP opinion in the EU for the treatment of moderate-to-severe atopic dermatitis in adults who are candidates for systemic therapy. Regulatory applications for the drug have also been submitted for review to several other countries, including the USA and Australia. This article summarizes the milestones in the development of abrocitinib leading to this first approval for the treatment of moderate-to-severe AD.

Abstract
Pruritus is a common dermatological condition and negatively impacts QOL. Persistent pruritus and excessive scratching behavior can lead to the itch-scratch cycle that exacerbates inflammatory skin diseases. Conventional antipruritic drugs, such as antihistamines, corticosteroids, or anticonvulsants, are sometimes insufficient. Recently, however, molecularly targeted drugs, such as IL-31 or IL-4 receptor-targeting antibodies, have become available or are under clinical trials, dramatically changing the clinical situation. In fact, some of these drugs can improve pruritus without the need for topical steroids. Taken together, these observations point to the importance of cytokine-mediated pruritus, further understanding of which may guide improved therapies.

Abstract
BACKGROUND In JADE COMPARE, abrocitinib improved severity of atopic dermatitis (AD) and demonstrated rapid itch relief. OBJECTIVES We examined clinically meaningful improvements in selected patient-reported outcomes (PROs). METHODS JADE COMPARE was a multicentre, phase 3 randomized, double-blind, placebo-controlled trial. Adults with moderate-to-severe AD were randomized 2:2:2:1 to receive 16 weeks of oral abrocitinib 200 or 100 mg once daily, dupilumab 300 mg subcutaneous injection every 2 weeks, or placebo, with background topical therapy. PROs included Dermatology Life Quality Index (DLQI), Patient-Oriented Eczema Measure (POEM), Night Time Itch Scale (NTIS), Pruritus and Symptoms Assessment for Atopic Dermatitis, Patient Global Assessment, SCORing Atopic Dermatitis, and Hospital Anxiety and Depression Scale. RESULTS At week 16, the proportion of patients achieving POEM scores <3 was 21.3% and 11.7% for 200 and 100 mg abrocitinib, 12.4% for dupilumab, and 4.8% for placebo (vs. abrocitinib, P < 0.0001 and P = 0.04). Proportion achieving ≥4-point improvement from baseline in NTIS severity was 64.3% and 52.4% for 200 and 100 mg abrocitinib, 54.0% for dupilumab, and 34.4% for placebo (vs. abrocitinib, P < 0.0001 and P = 0.007). Proportion achieving ≥4-point improvement from baseline in DLQI was 85.0% and 74.4% for 200 and 100 mg abrocitinib, 83.4% for dupilumab, and 59.7% for placebo (vs. abrocitinib, P < 0.0001 and P = 0.005). CONCLUSION Significant improvements in PROs were demonstrated with both abrocitinib doses vs. placebo, and abrocitinib 200 mg provided numerically greater effects compared with dupilumab in patients with moderate-to-severe AD.

Abstract
Accumulated evidence on type 2 inflammation-associated itch in atopic dermatitis has recently been reported. Crosstalk between the immune and nervous systems (neuroimmune interactions) is prominent in atopic dermatitis research, particularly regarding itch and inflammation. A comprehensive understanding of bidirectional neuroimmune interactions will provide insights into the pathogenesis of itch and its treatment. There is currently no agreed cure for itch in atopic dermatitis; however, increasing numbers of novel and targeted biologic agents have potential for its management and are in the advanced stages of clinical trials. In this review, we summarize and discuss advances in our understanding of type 2 inflammation-associated itch and implications for its management and treatment in patients with atopic dermatitis.

Abstract
INTRODUCTION While topical medications are the first line of treatment for mild-to-moderate atopic dermatitis, they are ineffective in individuals with diffuse disease and moderate-to-severe atopic itch. For these individuals, as well as those who do not respond to topical treatments, systemic medicines are typically essential and helpful. AREAS COVERED We conducted a review of the literature to identify established systemic therapies, novel biologic agents, and recent advances in the pathophysiology of atopic dermatitis. The review discusses these data, which show that the majority of atopic itch medications now in development target the type 2 immune axis and brain sensitization, two main etiologies of atopic itch. We emphasize the evidence, efficacy, and side effect profiles of currently available systemic medications for atopic itch, as well as future potential for tailored therapy. EXPERT OPINION We give our professional opinion on the current state of knowledge about atopic eczema pathogenesis and the innovative targets and therapies for atopic itch that include MRGPRX2, periostin, gabaergic medicines, and JAK/STAT inhibitors. Additionally, we discuss patient populations that stand to benefit the most from targeting these molecules or utilizing these drugs, as well as those who may face a disproportionate weight of adverse effects.

Abstract
Background A significant improvement in clinical signs was demonstrated with abrocitinib relative to placebo in adolescents with moderate‐to‐severe atopic dermatitis (AD) in three phase 3, randomized, double‐blinded, placebo‐controlled studies (JADE TEEN [ClinicalTrials.gov, NCT03796676], JADE MONO‐1 [NCT03349060] and JADE MONO‐2 [NCT03575871]). Objectives To evaluate the impact of abrocitinib on patient‐reported signs/symptoms, including sleep loss and quality of life among adolescents with moderate‐to‐severe AD. Methods JADE TEEN, JADE MONO‐1 and JADE MONO‐2 were conducted in the Asia‐Pacific region, Europe and North America and included patients aged 12–17 years with moderate‐to‐severe AD and inadequate response to ≥ 4 consecutive weeks of topical medication or treatment with systemic therapy for AD. Patients were randomly assigned (1 : 1 : 1, JADE TEEN; 2 : 2 : 1, JADE MONO‐1/‐2) to receive once‐daily oral abrocitinib (200 or 100 mg) or placebo for 12 weeks in combination with topical therapy (JADE TEEN) or as monotherapy (JADE MONO‐1/‐2). Data from adolescent patients in JADE MONO‐1/‐2 were pooled for these analyses. Results At week 12, more adolescents treated with abrocitinib (200 or 100 mg) vs. placebo achieved a ≥ 4‐point improvement from baseline in the Patient‐Oriented Eczema Measure in JADE TEEN (83.9% and 77.0% vs. 60.2%) and JADE MONO‐1/‐2 (83.0% and 69.4% vs. 43.5%) and a ≥ 6‐point improvement from baseline in the Children’s Dermatology Life Quality Index in JADE TEEN (73.8% and 67.5% vs. 56.5%) and JADE MONO‐1/‐2 (70.0% and 57.1% vs. 19.0%). Significant improvements in SCORing Atopic Dermatitis Visual Analog Scale for sleep loss scores were demonstrated with abrocitinib vs. placebo at weeks 2‐12 in JADE TEEN and JADE MONO‐1/‐2. Conclusions Patient‐reported signs/symptoms, including reduction of sleep loss and quality of life, were substantially improved with abrocitinib monotherapy or combination therapy relative to placebo in adolescents with moderate‐to‐severe AD.

Abstract
BACKGROUND Atopic dermatitis is a chronic, inflammatory condition causing a substantial burden to patients and caregivers. SHR0302 is an oral, highly selective, Janus kinase 1 inhibitor under investigation for inflammatory skin diseases. OBJECTIVE The aim of this study was to investigate the efficacy and safety of SHR0302 in Chinese patients with moderate to severe atopic dermatitis. DESIGN AND SETTING A randomized, double-blind, placebo-controlled, multicenter, phase II trial was conducted in China between October 2019 and August 2020. PARTICIPANTS Patients (n = 105) aged 18-75 years with moderate to severe dermatitis and nonresponsive or intolerant to topical or conventional systemic treatments were included. INTERVENTIONS Patients were randomly assigned in a ratio of 1:1:1 to receive SHR0302 4 mg once daily, SHR0302 8 mg once daily, or placebo for 12 weeks. MAIN OUTCOME MEASURES The primary efficacy endpoint was the proportion of patients achieving Investigator's Global Assessment (IGA) response (IGA of 0 [clear] or 1 [almost clear] with improvement of ≥2 grades) at week 12. Secondary efficacy assessments included Eczema Area and Severity Index (EASI) and pruritus Numerical Rating Scale (NRS) scores. RESULTS At week 12, IGA response was achieved in nine patients (25.7%; 90% confidence interval [CI] 13.6-37.9%; p = 0.022) in the SHR0302 4 mg group, 19 patients (54.3%; 90% CI 40.4-68.1%; p < 0.001) in the SHR0302 8 mg group, and two patients (5.7%; 90% CI 0.0-12.2%) in the placebo group. EASI75 was achieved in 51.4% (p = 0.013), 74.3% (p < 0.001), and 22.9% of patients in the SHR0302 4 mg, SHR0302 8 mg, and placebo groups, respectively, while an NRS ≥3-point improvement occurred in 65.7% (p < 0.001), 74.3% (p < 0.001), and 22.9% of patients, respectively. Treatment-emergent adverse events were reported in 60.0%, 68.6%, and 51.4% of patients in the SHR0302 4 mg, SHR0302 8 mg, and placebo groups, respectively. The adverse events were mild in most cases. Three serious adverse events were reported, all being worsening of atopic dermatitis. No serious infection was reported. CONCLUSIONS AND RELEVANCE Oral SHR0302 was effective and well tolerated in Chinese adult patients with moderate to severe atopic dermatitis.

Abstract
Abrocitinib, an oral once‐daily Janus kinase 1 selective inhibitor, is under development for the treatment of atopic dermatitis. This phase 1, nonrandomized, open‐label, single‐dose study (NCT03660241) investigated the effect of renal impairment on the pharmacokinetics, safety, and tolerability of abrocitinib and its metabolites following a 200‐mg oral dose. Twenty‐three subjects with varying degrees of renal function (normal, moderate, and severe impairment) were enrolled. Active moiety exposures were calculated as the sum of unbound exposures for abrocitinib and its active metabolites. For abrocitinib, the adjusted geometric mean ratios (GMRs; %) for area under the concentration‐time curve from time 0 extrapolated to infinite time and maximum plasma concentration were 182.91 (90% confidence interval [CI], 117.09‐285.71) and 138.49 (90% CI, 93.74‐204.61), respectively, for subjects with moderate renal impairment vs normal renal function; corresponding GMRs were 121.32 (90% CI, 68.32‐215.41) and 99.11 (90% CI, 57.30‐171.43) for subjects with severe impairment vs normal renal function. Metabolite exposures generally increased in subjects with renal impairment. The GMRs of unbound area under the concentration‐time curve from time 0 extrapolated to infinite time and maximum plasma concentration of active moiety were 210.20 (90% CI, 154.60‐285.80) and 133.87 (90% CI, 102.45‐174.92), respectively, for subjects with moderate renal impairment vs normal renal function. Corresponding values were 290.68 (90% CI, 217.39‐388.69) and 129.49 (90% CI, 92.86‐180.57) for subjects with severe renal impairment vs normal renal function. Abrocitinib was generally safe and well tolerated. Both moderate and severe renal impairment led to higher exposure to abrocitinib active moiety, suggesting that abrocitinib dose should be reduced by half for patients with moderate or severe renal impairment.

Abstract
BACKGROUND As new targeted therapies continue to emerge for atopic dermatitis (AD), comparisons between agents are necessary to inform clinical decision-making. OBJECTIVES Assess the efficacy of biologics and oral small molecules on the clinical signs, symptoms, and quality of life in AD. METHODS A systematic literature review identified phase II and III randomized clinical trials of biologics and oral small molecules in AD. Clinical benefit was assessed for three outcome measures: Eczema Area and Severity Index (EASI), Dermatology Life Quality Index (DLQI), and Peak Pruritus Numerical Rating Scale (PP-NRS) by performing a meta-analysis using the inverse variance heterogeneity model ((IVhet)). RESULTS The highest achievement of 75% reduction in EASI was seen with the higher dose of upadacitinib (30 mg) followed by abrocitinib and lebrikizumab, which outperformed dupilumab. Similarly, the highest proportion achieving at least a 4-point reduction of PP-NRS was seen with lebrikizumab followed by upadacitinib and abrocitinib which had greater reduction of itch than dupilumab. Abrocitinib had the greatest improvement in DLQI. CONCLUSIONS Upadacitinib, abrocitinib, and lebrikizumab had greater improvement of clinical signs, symptoms, and quality of life in AD compared to dupilumab and other targeted therapies.

Abstract
Aims: A chiral HPLC-MS/MS method for quantitation of an active metabolite (M2) of abrocitinib was validated in human plasma. Methods: Protein precipitation extraction and normal phase LC with baseline separation of five analytes (abrocitinib; isomeric metabolites M1, M2, M3 and M4) were achieved followed by mass spectrometric quantitation of M2 using positive-mode APCI. Results: With a 5-5000 ng/ml assay range using 100 μl K2EDTA aliquot, the assay provided short (17-min) runtime and robust separation up to approximately 330 injections on one column. Interday and intraday accuracy ranged from -6.80% to 13.4%; between-day and within-day precision was ≤10.4%. Conclusion: The method was used in multiple clinical studies, with excellent run passing rate and incurred sample reproducibility.

Abstract
Atopic dermatitis (AD) is a clinically heterogenous, inflammatory skin condition with a high impact on patients' daily activities that remains difficult to treat. The knowledge acquired over the last decade on AD pathophysiology and disease burden led to the development of new targeted therapeutic options that enable clinicians to better manage AD patients. The JAK/STAT signaling pathway modulates several immune pathways (T helper (Th)1, Th2, Th17, and Th22 cells) that have been found to be involved in AD pathogenesis. For this reason, JAK inhibitors emerged as a possible therapy for AD. Baricitinib, upadacitinib, and abrocitinib are the three oral JAK inhibitors already approved or in advanced clinical development for this purpose. The results showed that this drug class is highly effective achieving symptomatic relief (itch control) in the short term, as well as improving disease severity in the short and medium term. However, their efficacy should be balanced with possible side effects, that have been reported in clinical trials. More data on the long-term efficacy and safety, as well as from head-to-head comparisons and from real-world setting will be crucial to position oral JAK inhibitors in the AD therapeutic armamentarium.

Abstract
Question What is the short-term efficacy and safety of oral abrocitinib in adolescents with moderate-to-severe atopic dermatitis? Findings In the randomized clinical trial JADE TEEN, a phase 3 study of abrocitinib in combination with topical therapy that included 285 adolescents with moderate-to-severe atopic dermatitis, significantly more adolescents who were treated with abrocitinib compared with placebo achieved an Investigator’s Global Assessment response or clear or almost clear, at least 75% improvement in Eczema Area and Severity Index response, and/or at least 4-point improvement in Peak Pruritus Numerical Rating Scale response. Serious adverse events were reported for fewer than 3% of patients. Meaning Oral abrocitinib in combination with topical therapy was effective and well-tolerated in adolescents with moderate-to-severe atopic dermatitis. Importance Dupilumab subcutaneous injection is approved for treating moderate-to-severe atopic dermatitis (AD) in adolescents, but there has been too little research on an efficacious systemic oral treatment with a favorable benefit-risk profile for adolescents with moderate-to-severe AD. Objective To investigate the efficacy and safety of oral abrocitinib plus topical therapy in adolescents with moderate-to-severe AD. Design, Setting, and Participants The phase 3, randomized, double-blind, placebo-controlled study JADE TEEN was conducted in countries of the Asia–Pacific region, Europe, and North America in patients aged 12 to 17 years with moderate-to-severe AD and an inadequate response to 4 consecutive weeks or longer of topical medication or a need for systemic therapy for AD. The study was conducted between February 18, 2019, and April 8, 2020. The data were analyzed after study completion. Interventions Patients were randomly assigned 1:1:1 to receive once-daily oral abrocitinib, 200 mg or 100 mg, or placebo for 12 weeks in combination with topical therapy. Main Outcomes and Measures Coprimary end points were achievement of an Investigator’s Global Assessment (IGA) response of clear (0) or almost clear (1) with improvement of 2 or more grades from baseline (IGA 0/1) and 75% or greater improvement from baseline in Eczema Area and Severity Index (EASI-75) response at week 12. Key secondary end points included 4-point or greater improvement in Peak Pruritus Numerical Rating Scale (PP-NRS4) at week 12. Adverse events (AEs) were monitored. Results This study included 285 adolescents with moderate-to-severe AD (145 boys [50.9%] and 140 girls [49.1%]), of whom 160 (56.1%) were White and 94 (33.0%) were Asian; the median age was 15 years (interquartile range 13-17 years). Substantially more patients treated with abrocitinib (200 mg or 100 mg) vs placebo achieved an IGA response of 0/1 (46.2%; 41.6% vs 24.5%; P < .05 for both), EASI-75 (72.0%; 68.5% vs 41.5%; P < .05 for both), and PP-NRS4 (55.4%; 52.6% vs 29.8%; P < .01 for 200 mg vs placebo) at week 12. Adverse events were reported for 59 (62.8%), 54 (56.8%), and 50 (52.1%) patients in the 200 mg, 100 mg, and placebo groups, respectively; nausea was more common with abrocitinib, 200 mg (17 [18.1%]) and 100 mg (7 [7.4%]). Herpes-related AEs were infrequent; 1 (1.1%), 0, and 2 (2.1%) patients had serious AEs. Conclusions and Relevance This randomized clinical trial found that oral abrocitinib combined with topical therapy was significantly more effective than placebo with topical therapy in adolescents with moderate-to-severe AD, with an acceptable safety profile.

Abstract
The JAK-STAT pathway is involved in the signaling of multiple cytokines driving cutaneous inflammation in atopic dermatitis (AD). Janus kinase (JAK) inhibitors target individual receptor-associated kinases, thereby preventing the mediation of inflammatory signals. Several JAK inhibitors with varying mechanism of action, potency, and safety represent potential therapeutic options for AD in both topical and systemic application. The JAK1/2 selective JAK inhibitor baricitinib was the first substance from this class of drugs approved by the EMA for the systemic oral treatment of AD. The clinical development program of the JAK1 selective inhibitors upadacitinib and abrocitinib is finalized with positive results for AD. The PAN-JAK inhibitor delgocitinib was the first substance being approved for the treatment of AD (in Japan). This review article covers the rising data on investigational and approved JAK inhibitors in the context of the treatment of AD.

Short-Term Effectiveness and Safety of Biologics and Small Molecule Drugs for Moderate to Severe Atopic Dermatitis: A Systematic Review and Network Meta-Analysis. Life (Basel) 2021; 11:life11090927. [PMID: 34575076 PMCID: PMC8470048 DOI: 10.3390/life11090927] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2021] [Revised: 08/26/2021] [Accepted: 09/04/2021] [Indexed: 11/16/2022] Open
Abstract
Background: Some Network Meta-analysis (NMA) has been published regarding atopic dermatitis (AD). These studies have considered drugs under investigation both in monotheraphy or in combination with topical corticosteroids, as well as systemic immunosuppressant therapies. The objective of this study is to evaluate the efficacy and safety of biological agents and small molecules in AD. Methods: A systematic review and NMA of biologics agents and small molecules in AD was performed. A literature search was performed using MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials for clinical trials and systematic reviews between January 2000 and 19 December 2020. Only randomized clinical trials (RCTs) were included. It was limited to English language and adult human subjects. Two networks were evaluated: monotherapy and combination with TCS. The two primary outcomes were Eczema Area and Severity Index (EASI) 75 and EASI 90 change from baseline to week 12–16, depending on source study cut-off. The Cochrane’s Risk of Bias tool 2011 update was used to analyze the risk of bias, focused on the primary objectives. Results: 30 RCTs (included in 26 publications) were included in the systematic review. Finally, 23 RCTs were included in the quantitative analysis (14 RCTs including 3582 patients in monotherapy; and 9 RCTs including 3686 patients with TCS). In monotherapy, a higher percentage of patients achieving EASI-75 was obtained with Upadacitinib 30 mg [OR: 18.90 (13.94; 25.62)] followed by Abrocitinib 200 mg [OR = 11.26 (7.02; 18.05)] and Upadacitinib 15 mg [OR: 10.89 (8.13; 14.59)]. These results were also observed in studies where the use of topical corticosteroid (TCS) was allowed (OR Upadacitinib 30 mg = 9.43; OR Abrocitinib 200 mg = 6.12; OR Upadacitinib 15 mg = 5.20). Regarding IGA, the percentage of patients achieving IGA0/1 was higher with both doses of Upadacitinib 30 mg [OR: 19.13 (13.14; 27.85)] and 15 mg [OR = 10.95 (7.52; 15.94). In studies where the use of TCS were allowed, however, the dose of Abrocitinib 200 mg [OR = 6.10 (3.94; 9.44)] showed higher efficacy than Upadacitinib 15 mg [OR = 5.47 (3.57; 8.41)]. Regarding safety, the drugs with the highest probability of presenting adverse effects were the Janus kinases (JAK) inhibitors, Upadacitinib and Abrocitinib in monotherapy and Baricitinib in combination with TCS. Discussion: Some risks of bias have been found, which must be taken into account when interpreting the results. The funnel plot shows a possible publication bias that may underestimate the efficacy of drugs. Upadacitinib and Abrocitinib are the drugs with the highest efficacy, both in monotherapy and in association with TCS. However, they were also those associated with the highest risk of adverse effects, showing monoclonal antibodies better safety profile. Limitations: We have included molecules still in the development phase as well studies completed and presented at conferences and with data available in Trialsgov® but not published yet. Several molecules’ development had included a small number of patients from 12 to 17 years of age, without being able to differentiate the results from the adult population. Other: Founding: None. PROSPERO database registration number CRD42021225793.

Abstract
IMPORTANCE Atopic dermatitis (AD) is a chronic, recurrent, inflammatory skin disease with an unmet need for treatments that provide rapid and high levels of skin clearance and itch improvement. OBJECTIVE To assess the safety and efficacy of upadacitinib vs dupilumab in adults with moderate-to-severe AD. DESIGN, SETTING, AND PARTICIPANTS Heads Up was a 24-week, head-to-head, phase 3b, multicenter, randomized, double-blinded, double-dummy, active-controlled clinical trial comparing the safety and efficacy of upadacitinib with dupilumab among 692 adults with moderate-to-severe AD who were candidates for systemic therapy. The study was conducted from February 21, 2019, to December 9, 2020, at 129 centers located in 22 countries across Europe, North and South America, Oceania, and the Asia-Pacific region. Efficacy analyses were conducted in the intent-to-treat population. INTERVENTIONS Patients were randomized 1:1 and treated with oral upadacitinib, 30 mg once daily, or subcutaneous dupilumab, 300 mg every other week. MAIN OUTCOMES AND MEASURES The primary end point was achievement of 75% improvement in the Eczema Area and Severity Index (EASI75) at week 16. Secondary end points were percentage change from baseline in the Worst Pruritus Numerical Rating Scale (NRS) (weekly average), proportion of patients achieving EASI100 and EASI90 at week 16, percentage change from baseline in Worst Pruritus NRS at week 4, proportion of patients achieving EASI75 at week 2, percentage change from baseline in Worst Pruritus NRS (weekly average) at week 1, and Worst Pruritus NRS (weekly average) improvement of 4 points or more at week 16. End points at week 24 included EASI75, EASI90, EASI100, and improvement of 4 points or more in Worst Pruritus NRS from baseline (weekly average). Safety was assessed as treatment-emergent adverse events in all patients receiving 1 or more dose of either drug. RESULTS Of 924 patients screened, 348 (183 men [52.6%]; mean [SD] age, 36.6 [14.6] years) were randomized to receive upadacitinib and 344 were randomized to receive dupilumab (194 men [56.4%]; mean [SD] age, 36.9 [14.1] years); demographic and disease characteristics were balanced among treatment groups. At week 16, 247 patients receiving upadacitinib (71.0%) and 210 patients receiving dupilumab (61.1%) achieved EASI75 (P = .006). All ranked secondary end points also demonstrated the superiority of upadacitinib vs dupilumab, including improvement in Worst Pruritus NRS as early as week 1 (mean [SE], 31.4% [1.7%] vs 8.8% [1.8%]; P < .001), achievement of EASI75 as early as week 2 (152 [43.7%] vs 60 [17.4%]; P < .001), and achievement of EASI100 at week 16 (97 [27.9%] vs 26 [7.6%]; P < .001). Rates of serious infection, eczema herpeticum, herpes zoster, and laboratory-related adverse events were higher for patients who received upadacitinib, whereas rates of conjunctivitis and injection-site reactions were higher for patients who received dupilumab. CONCLUSIONS AND RELEVANCE During 16 weeks of treatment, upadacitinib demonstrated superior efficacy vs dupilumab in patients with moderate-to-severe AD, with no new safety signals.

Abstract
Janus kinase (JAK) inhibitors are emerging treatments for atopic dermatitis (AD). Due to this novel role as a therapeutic option for patients with AD, we aimed to review current evidence on the pathophysiology and the safety and adverse effects (AEs) of oral JAK inhibitors for the treatment of AD utilizing the key terms atopic dermatitis, JAK inhibitors, and adverse effect or event. Our study indicated that oral JAK inhibitors have a moderate safety profile for use in AD in several reviews and phase II or III clinical trials. Headaches, nausea, and nasopharyngitis are the most commonly reported systemic AEs. Furthermore, acne, herpes simplex, herpes zoster, and eczema herpeticum are the most commonly recorded dermatological AEs. Current evidence indicates JAK inhibitors may also have less association with some of the serious AEs, although there is potential for increased risk of asthma, acute pancreatitis, neutropenia, and thrombocytopenia. Whereas data remain limited for the long-term safety of JAK inhibitor use in patients with AD, many ongoing clinical trials have promising preliminary results.

Abstract
Background: Atopic dermatitis is a chronic, relapsing and remitting disease that can be difficult to treat despite a recently approved biologic therapy targeting IL-4/IL-13 receptor. Oral janus kinase inhibitors (JAKi) represent a novel therapeutic class of targeted therapy to treat moderate-to-severe atopic dermatitis (AD). Objective: To review the efficacy, safety, and pharmacokinetic characteristics of oral JAKi in the treatment of AD. Methods: A PRISMA systematic review was conducted using MEDLINE, EMBASE (Ovid), and PubMed databases for studies assessing the efficacy, safety, and/or pharmacokinetic properties of oral forms of JAKi in the treatment of AD in pediatric or adult populations from inception to June 2021. Results: 496 papers were reviewed. Of 28 articles that underwent full text screening, 11 met our inclusion criteria for final qualitative review. Four studies examined abrocitinib; three studies examined baricitinib; three examined upadacitinib and one examined gusacitinib (ASN002). Significant clinical efficacy and a reassuring safety profile was reported for all JAKi agents reviewed. Rapid symptom control was reported for abrocitinib, baricitinib and upadacitinib. Limitations: Given the relatively limited evidence for each JAKi and the differences in patient eligibility criteria between studies, the data was not deemed suitable for a meta-analysis at this time. Conclusion: Given their ability to achieve rapid symptom control with a reassuring safety profile, we recommend considering the use of JAKi as a reliable systemic treatment option for adult patients with moderate-to-severe AD, who are unresponsive to topical or skin directed treatments.

Abstract
Background Pivotal phase III studies demonstrated that abrocitinib, an oral, once-daily, JAK1-selective inhibitor, is effective treatment for moderate-to-severe atopic dermatitis (AD) as monotherapy and in combination with topical therapy. Objective The aim of this study was to evaluate the long-term safety of abrocitinib 200 mg and 100 mg in an integrated analysis of a phase IIb study, four phase III studies, and one long-term extension study. Methods Two cohorts were analyzed: a placebo-controlled cohort from 12- to 16-week studies and an all-abrocitinib cohort including patients who received one or more abrocitinib doses. Adverse events (AEs) of interest and laboratory data are reported. Results Total exposure in the all-abrocitinib cohort (n = 2856) was 1614 patient-years (PY); exposure was ≥ 24 weeks in 1248 patients and ≥ 48 weeks in 606 (maximum 108 weeks). In the placebo-controlled cohort (n = 1540), dose-related AEs (200 mg, 100 mg, placebo) were nausea (14.6%, 6.1%, 2.0%), headache (7.8%, 5.9%, 3.5%), and acne (4.7%, 1.6%, 0%). Platelet count was reduced transiently in a dose-dependent manner; 2/2718 patients (200-mg group) had confirmed platelet counts of < 50 × 103/mm3 at week 4. Incidence rates (IRs) were 2.33/100PY and 2.65/100 PY for serious infection, 4.34/100PY and 2.04/100PY for herpes zoster, and 11.83/100PY and 8.73/100PY for herpes simplex in the 200-mg and 100-mg groups, respectively. IRs for nonmelanoma skin cancer, other malignancies, and major adverse cardiovascular events were < 0.5/100PY for both doses. Five venous thromboembolism events occurred (IR 0.30/100PY), all in the 200-mg group. There were three deaths due to gastric carcinoma (diagnosed at day 43), sudden death, and COVID-19. Conclusion Abrocitinib, with proper patient and dose selection, has a manageable tolerability and longer-term safety profile appropriate for long-term use in patients with moderate-to-severe AD.

Abstract
Background Current therapeutic options for atopic dermatitis (AD) are limited. Janus kinase (JAK) inhibitors may be viable alternatives. Objectives To assess the efficacy and safety of JAK inhibitors for AD treatment. Methods We searched PubMed, Embase, the Cochrane Controlled Register of Trials, Web of Science, Global Resource of Eczema Trials database, and ClinicalTrials.gov from inception to September 1, 2020. Randomized clinical trials (RCTs) comparing JAK inhibitors with placebo/vehicle treatment for AD patients were included. The primary study outcomes included (1) the change (%) from the Eczema Area and Severity Index (EASI) baseline expressed as weighted mean difference (WMD) and 95% confidence interval (95% CI), and (2) the Investigator's Global Assessment (IGA) response and safety outcomes expressed as relative risk (RR) and 95% CI. Results We included 14 RCTs published in 13 studies (3,822 patients). Treatment with JAK inhibitors significantly improved IGA response (RR 2.83, 95% CI 2.25–3.56, p < 0.001) and EASI score (WMD −28.82, 95% CI −34.48 to −23.16, p < 0.001). JAK inhibitor treatment achieved the largest improvement in both IGA response (RR 3.59, 95% CI 2.66–4.84, p < 0.001) and EASI score (WMD −42.00, 95% CI −48.64 to −35.36, p < 0.001) by week 4 of treatment. Topical JAK inhibitors were significantly more efficacious than oral inhibitors. Upadacitinib treatment for 4 weeks was most effective in reducing EASI score (WMD −53.92, 95% CI −69.26 to −38.58, p < 0.001), while abrocitinib for 4 weeks led to the most effective IGA response (RR 5.47, 95% CI 2.74–10.93, p < 0.001). There was no difference in the frequency of adverse events (AEs) leading to discontinuation; however, JAK inhibitors use, especially abrocitinib, led to a higher incidence of treatment-emergent AEs (RR 1.25, 95% CI 1.10–1.42, p = 0.001). Conclusion Our results imply that JAK inhibitors are an effective and safe AD treatment. Nevertheless, further trials with longer duration and head-to-head comparisons of different JAK inhibitors are needed.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory skin disorder associated with heterogenous presentation and often immense patient burden. Safe, targeted treatment options are currently limited. This focused review of the published literature, including clinical trial results, case reports, and abstracts, as well as presentations from scientific meetings and data from industry press releases, describes the use of topical and systemic Janus kinase (JAK) inhibitors in the treatment of AD. New topical JAK inhibitors include ruxolitinib (JAK1/2) and delgocitinib (pan-JAK). Ruxolitinib cream met all primary and secondary endpoints in phase 3 clinical trials for mild-to-moderate AD with minimal treatment-emergent adverse events. Delgocitinib ointment was recently approved in Japan for pediatric and adult AD. Oral JAK inhibitors include baricitinib (JAK1/2), abrocitinib (JAK1-selective), and upadacitinib (JAK1-selective). All 3 met primary and secondary endpoints across numerous trials for moderate-to-severe AD. Treatment-emergent adverse events were mainly mild to moderate and included acne, nausea, headache, upper respiratory tract infection, and to a lesser degree, herpes infection and selected laboratory abnormalities. JAK inhibitors hold great promise as the next generation of targeted AD therapy. While their outstanding efficacy is balanced by a favorable safety profile in clinical trials, real-world data are needed to better understand long-term safety, durability, and treatment success.

Abstract
Atopic dermatitis (AD) is a chronic heterogeneous condition characterized by erythematous, pruritic, and inflamed skin. Janus kinase (JAK) inhibitors are a new class of drugs that target proteins in the Janus kinase-signal transducer and activator of transcription (JAK-STAT) pathway. These drugs can be administered orally or topically to inhibit signaling of the JAK-STAT pathway and minimize the production of proinflammatory cytokines. The efficacy and safety of JAK inhibitors have been investigated in phase 2 and 3 clinical trials for AD. The safety of new medications, which are immunosuppressive by nature, is of utmost concern for the prescriber and patient alike. Herein we summarize the safety results of clinical trials using oral abrocitinib, upadacitinib, and baricitinib, as well as topical ruxolitinib and delgocitinib for the treatment of AD. The most prevalent (2-5% occurrence rate) treatment-emergent adverse events from oral JAK inhibitor use in AD were nausea, upper respiratory tract infection, headache, herpes zoster, herpes simplex, acne, increased blood creatine phosphokinase levels, and decreased platelet counts. Topical JAK inhibitors were not associated with systemic effects. All studies reported that JAK inhibitors were well tolerated in patients with AD in comparison with the control group. While the use of JAK inhibitors in patients suffering from AD is very promising, trials reported to date are of short duration (maximum 16 weeks), and more information on the long-term safety of these novel agents is required.

Abrocitinib induction, randomized withdrawal, and retreatment in patients with moderate-to-severe atopic dermatitis: Results from the JAK1 Atopic Dermatitis Efficacy and Safety (JADE) REGIMEN phase 3 trial. J Am Acad Dermatol 2021; 86:104-112. [PMID: 34416294 DOI: 10.1016/j.jaad.2021.05.075] [Citation(s) in RCA: 61] [Impact Index Per Article: 20.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Revised: 05/20/2021] [Accepted: 05/23/2021] [Indexed: 12/30/2022]
Abstract
BACKGROUND The heterogeneous course of moderate-to-severe atopic dermatitis necessitates treatment flexibility. OBJECTIVE We evaluated the maintenance of abrocitinib-induced response with continuous abrocitinib treatment, dose reduction or withdrawal, and response to treatment reintroduction following flare (JAK1 Atopic Dermatitis Efficacy and Safety [JADE] REGIMEN: National Clinical Trial 03627767). METHODS Patients with moderate-to-severe atopic dermatitis responding to open-label abrocitinib 200 mg monotherapy for 12 weeks were randomly assigned in a 1:1:1 ratio to blinded abrocitinib (200 or 100 mg) or placebo for 40 weeks. Patients experiencing flare received rescue treatment (abrocitinib 200 mg plus topical therapy). RESULTS Of 1233 patients, 798 responders to induction (64.7%) were randomly assigned. The flare probability during maintenance was 18.9%, 42.6%, and 80.9% with abrocitinib 200 mg, abrocitinib 100 mg, and placebo, respectively. Among patients with flare in the abrocitinib 200 mg, abrocitinib 100 mg, and placebo groups, 36.6%, 58.8%, and 81.6% regained investigator global assessment 0/1 response, respectively, and 55.0%, 74.5%, and 91.8% regained eczema area and severity index response, respectively, with rescue treatment. During maintenance, 63.2% and 54.0% of patients receiving abrocitinib 200 and 100 mg, respectively, experienced adverse events. LIMITATIONS The definition of protocol-defined flare was not established, limiting the generalizability of findings. CONCLUSION Induction treatment with abrocitinib was effective; most responders continuing abrocitinib did not flare. Rescue treatment with abrocitinib plus topical therapy effectively recaptured response.

Abstract
BACKGROUND Atopic dermatitis (AD) is a chronic relapsing inflammatory skin disorder. Though corticosteroids are the cornerstone of therapy, the Janus kinase inhibitor abrocitinib has shown promise in recent clinical trials for the treatment of AD. OBJECTIVE To assess the overall efficacy and safety of abrocitinib in moderate to severe AD. METHODS All randomized controlled trials (RCTs) evaluating the efficacy and safety of abrocitinib in moderate to severe AD were included in the meta-analysis. RESULTS The pooled analysis revealed a significant proportion of patients achieving Investigator's Global Assessment (IGA) response (RR = 3.52, 95% CI; 2.78-4.46, p < .00001), Eczema Area and Severity Index (EASI) response (RR = 3.35, 95% CI; 2.54-4.41, p < .00001), and Peak Pruritus Numerical Rating Score (PP-NRS) response (RR = 2.54,95% CI; 1.95-3.30, p < .00001) in abrocitinib arm compared to the placebo arm. Moreover, the pooled analysis also suggested that treatment-emergent adverse events (TAEs) were relatively higher with abrocitinib than placebo (R.R. = 1.17; 95% CI; 1.06-1.29, p = .002). CONCLUSIONS This meta-analysis showed that abrocitinib had a significant beneficial effect and tolerable adverse effect profile in patients of AD. Dose regimens of 200 and 100 mg seemed to have similar benefits. However, long-term trials are needed for corroboration.Key pointsAbrocitinib is emerging as a potential treatment option for moderate to severe atopic dermatitis.The pooled analysis from 4 RCTs demonstrated significant effectiveness of abrocitinib in both physician and patient-reported outcomes like IGA, EASI, and PP-NRS. The drug was also well-tolerated across the trials.The number needed to treat (NNT) for all efficacy outcomes was low suggesting clinically desirable benefits with the use of abrocitinib.

Abstract
Pruritus is the most burdensome and prevalent symptom in patients suffering from atopic dermatitis. Treating atopic itch has historically been a challenge due to multiple underlying mechanisms within its pathogenesis and an incomplete understanding of them. In recent years, our understanding of these mechanisms have increased tremendously and subsequently, new treatments have reached the market that target the pathophysiology of atopic itch from different angles. In addition, there are several promising new treatments currently in development and trials. In the current article, we discuss these currently available treatment options, their available evidence and efficacy, and highlight some of the more recent advancements in the field.

Abstract
Atopic dermatitis (AD) is a common inflammatory skin disorder characterized by recurrent eczematous lesions and intense itch. Although it most often starts in infancy and affects children, it is also highly prevalent in adults. In this article, the main aspects of AD have been updated, with a focus on the pathogenetic and therapeutic aspects. The pathogenesis of AD is complex, and it is evident that a strong genetic predisposition, epidermal dysfunction, skin microbiome abnormalities, immune dysregulation, and the neuroimmune system are critical in AD development. Mutations in the genes associated with disrupted epidermal barrier, exaggerated pathological inflammation and inadequate antimicrobial peptides can promote enhanced Th2 inflammation and mediate pruritus. Current understanding of etiology highlights gut microbial diversity, NK cell deficiency, and different immunological phenotype with age and race. For topical anti-inflammatory treatment for mild-to-severe AD, phosphodiesterase 4 inhibitors (PDE-4), JAK inhibitors, and microbiome transplantation with Roseomonas mucosa provided more management selections. The treatment of moderate-to-severe AD has been limited to merely symptomatic and relatively nonspecific immunosuppressive approaches. In-depth understanding of the pathogenesis of AD has led to the development of innovative and targeted therapies, such as biologic agents targeting interleukin (IL)-4, IL-13 and JAK/STAT inhibitors. Other potential therapeutic agents for AD include agents targeting the T helper (Th) 22 and Th17/IL23 pathway. Antipruritic therapy and complementary probiotics therapy have also been reviewed.

Abstract
PURPOSE OF REVIEW To provide a cutting-edge overview of recent developments in topical and systemic therapeutic approaches for the treatment of atopic dermatitis (AD). RECENT FINDINGS Growing knowledge about key pathways in AD and stratification of patient's subgroups have set the basis for a new era of targeted topical and systemic therapy in AD.Different aspects have to be considered in the decision process for topical versus systemic therapy. Further on, co-factors from the patient's side as well as the side of the substances determine the choice of a particular drug/drug type.Tailored medicine in AD treatment comprises drugs of the group of small molecules such as topical Janus kinases-signal transducer and activator of transcription (JAK-STAT) inhibitors or phosphodiesterase 4 inhibitors, and JAK-STAT inhibitors for oral use, as well as monoclonal antibodies for subcutaneous use, which target key cytokines or cytokine receptors in AD pathogenesis. SUMMARY The current stepwise treatment approaches, which are settled on basic therapy and structured patient education and gradually expanded depending on the severity of the disease by stronger topical or even systemic measures, will have to be adapted to the rapid development in the therapeutic field, mirrored by an impressive high number of ongoing clinical studies as well as novel drugs at late stages of clinical trials with so far quite promising results.

Abstract
BACKGROUND Atopic dermatitis (AD) is one of the serious global problems. There were wide concerns about whether Janus kinase (JAK) inhibitor was an alternative treatment for AD. METHOD Eight databases were searched from the earliest publication date available to January 2, 2021. We included randomized controlled trials comparing JAK inhibitors with control treatment for AD. Data were pooled using Stata.14 software and performed as mean differences (MD) and risk ratios (RR) with 95% CIs. We did subgroup analysis based on specific outcomes. RESULTS A total of studies, ten randomized controlled trials, with 2583 patients were included in the final synthesis. This meta-analysis showed JAK inhibitor resulted in significant improvement on EASI total score (MD = -0.31; 95%CI, -0.46 to -0.17; p = .000; I2 = 90.0%, p = .000) and pruritus numerical rating scale (NRS) score (MD = -1.15; 95%CI, -1.48 to -0.83; p = .000; I2 = 95.9%, p = .000), without the higher risk of total adverse effects (RR = 1.02; 95%CI, 0.90-1.16; p = .745; I2 =27.9%, p = .206). CONCLUSIONS JAK inhibitor was a promising option for atopic dermatitis. More data and surveillance will be needed to identify efficacy, safety, and the risk of adverse effects.

Abstract
Introduction: Atopic dermatitis (AD) is the most common inflammatory skin disease. It has a complex pathophysiology, with a combination of immune dysregulation and intrinsic barrier defects driving cutaneous inflammation and allergic symptomatology. The IL-4, IL-13 and IL-31 inflammatory pathways have been identified as hallmark features in the pathogenesis of the disease, contributing uniquely and synergistically to immune and barrier abnormalities as well as the key symptoms, such as pruritis. Novel therapeutics that target these pathways have been under development to find treatments for AD.Areas covered: This review discusses the IL-4, IL-13 and IL-31 pathways in AD. We will also detail novel targeted therapeutics that have recently been or are currently in clinical trials for AD. A literature search was conducted by querying Scopus, Google Scholar, PubMed, and Clinicaltrials.gov up to January 2021 using combinations of the search terms 'IL-4' 'IL-13' 'IL-31' 'atopic dermatitis' 'immune pathway' 'biologics' 'novel therapeutics' 'JAK/STAT inhibitors.'Expert opinion: The complex pathophysiology of AD advocates for innovation. Novel minimally invasive sampling modalities such as tape stripping will allow for a broader characterization of the immunomechanisms behind AD pathophysiology. This will allow for the continued development of a personalized medicine approach to treat AD.

Janus kinase inhibitors in dermatology: Part I. A comprehensive review. J Am Acad Dermatol 2021; 86:406-413. [PMID: 34246698 DOI: 10.1016/j.jaad.2021.07.002] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2021] [Revised: 06/29/2021] [Accepted: 07/01/2021] [Indexed: 01/12/2023]
Abstract
The Janus kinase-signal transducer and activator of transcription (JAK-STAT) intracellular signaling pathway is utilized by many proinflammatory molecules to mediate downstream effects and activate gene transcription. Activation of the JAK-STAT pathway contributes to a number of inflammatory dermatoses. Clinical trials and smaller studies have demonstrated the efficacy of JAK inhibitors in the treatment of a variety of dermatologic conditions. Here, we review the use of JAK inhibitors for the treatment of a wide range of dermatologic diseases in a two-part review series.

Impact of Oral Abrocitinib Monotherapy on Patient-Reported Symptoms and Quality of Life in Adolescents and Adults with Moderate-to-Severe Atopic Dermatitis: A Pooled Analysis of Patient-Reported Outcomes. Am J Clin Dermatol 2021; 22:541-554. [PMID: 33954933 PMCID: PMC8200343 DOI: 10.1007/s40257-021-00604-9] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/30/2021] [Indexed: 12/28/2022]
Abstract
BACKGROUND Atopic dermatitis imparts a substantial patient burden, including itch, sleep disturbance, and decreased health-related quality of life. OBJECTIVE This analysis evaluated changes in patient-reported outcomes of disease-specific signs/symptoms and health-related quality of life in adult and adolescent patients with moderate-to-severe atopic dermatitis treated with once-daily oral abrocitinib 200-mg or 100-mg monotherapy. METHODS Pooled data from one phase IIb (NCT02780167) and two phase III (NCT03349060, JADE MONO-1; NCT03575871, JADE MONO-2) monotherapy trials in adult and adolescent patients with moderate-to-severe atopic dermatitis were analyzed. Patient-reported outcome assessments included: global severity, itch, and multi-item measures that assess other signs and symptoms of atopic dermatitis. Additional patient-reported outcome assessments measured depression, anxiety, fatigue, disease-specific and general health-related quality of life, and work and general productivity among employed patients. RESULTS Overall, 942 patients were included in this analysis. Improvements were observed from the first post-baseline assessment to week 12 across all patient-reported outcomes, including Patient Global Assessment (PtGA) score of 0/1 (35.5%, 19.8%, and 5.9% for 200 mg, 100 mg, and placebo, respectively), ≥ 4-point improvement in Night Time Itch Scale (NTIS; 57.0%, 42.7%, and 12.7%), change from baseline in Patient-Oriented Eczema Measure (POEM) score (- 11.4, - 8.2, and - 3.4), 1-point improvement in Pruritus and Symptoms Assessment for Atopic Dermatitis (PSAAD; 75.2%, 65.1%, and 33.5%), Hospital Anxiety and Depression Scales (HADS) anxiety (- 2.0, - 1.7, and - 1.0) and depression (- 1.7, - 1.3, and - 0.1). CONCLUSIONS Abrocitinib monotherapy improved disease-specific signs/symptoms and health-related quality of life across multiple domains as reported by adult and adolescent patients with moderate-to-severe atopic dermatitis, complementing clinician-reported efficacy and safety outcomes. CLINICAL TRIAL REGISTRATION NCT02780167 (registered 23 May, 2016), NCT03349060 (registered 21 November, 2017), NCT03575871 (registered 3 July, 2018).

Effectiveness and Safety of Abrocitinib in Patients with Moderate-to-Severe Atopic Dermatitis: A Systematic Review and Meta-Analysis of Randomized Clinical Trials. Dermatol Res Pract 2021; 2021:8382761. [PMID: 34257642 PMCID: PMC8245258 DOI: 10.1155/2021/8382761] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2021] [Revised: 06/06/2021] [Accepted: 06/11/2021] [Indexed: 11/18/2022] Open
Abstract
Background Atopic dermatitis (AD) is a complex, chronic, inflammatory skin disease characterized by pruritic, intense itching, and eczematous lesions affecting about 25% of children and 2% to 3% of adults worldwide. Abrocitinib is a selective inhibitor of Janus kinase-1 (JAK1) enzyme inhibiting the inflammatory process. Therefore, we aimed to assess the efficacy and safety of abrocitinib for moderate-to-severe AD. Methods We systematically searched PubMed, Cochrane, Web of Science, Scopus, and EczemATrials till Feb 1, 2021, for reliable trials. The analysis was conducted using an inverse-variance method. The results were pooled as mean difference/event rate and 95% confidence interval. Results Abrocitinib 100 mg and 200 mg were associated with higher IGA response, EASI-50% responders, EASI-75% responders, EASI-90% responders, number of participants with at least 4-point improvements in NRS, and quality of life measured by DLQI and CDLQI than placebo. Also, 100 mg and 200 mg were associated with lower SCORAD index, %BSA, PSAAD index, and POEM index than placebo. Abrocitinib 100 mg and 200 mg were not associated with adverse events such as upper respiratory tract infection, nasopharyngitis, dermatitis, atopic, any serious adverse events, and death. Conclusion Abrocitinib in dose 100 mg or 200 mg is an effective, well-tolerated, and promising drug in treating patients with moderate-to-severe atopic dermatitis. However, the analysis favored the efficacy of abrocitinib 200 mg over 100 mg, but side effects such as nausea and headache are likely to occur more with 200 mg.

Comparative efficacy and safety of systemic therapies used in moderate-to-severe atopic dermatitis: a systematic literature review and network meta-analysis. J Eur Acad Dermatol Venereol 2021; 35:1797-1810.

Abstract
Given the lack of head-to-head studies of systemic therapies in moderate-to-severe atopic dermatitis (AD), network meta-analyses (NMAs) can provide comparative efficacy and safety data to inform clinical decision-making. In this NMA, eligible randomized controlled trials (RCTs) published before 24 October 2019 were identified by a systematic literature review. Short-term (12-16 weeks) efficacy (Investigator's Global Assessment [IGA] and Eczema Area and Severity Index [EASI] responses), patient-reported outcomes (PROs) and safety data from each trial were abstracted and analysed separately for monotherapy and combination therapy (systemic plus topical anti-inflammatory therapy). RCTs were analysed in fixed-effects and random-effects Bayesian NMA models. Overall, 19 phase 2 and phase 3 RCTs of abrocitinib, baricitinib, dupilumab, lebrikizumab, nemolizumab, tralokinumab and upadacitinib were included. In monotherapy RCTs, upadacitinib 30 mg once daily (QD) had the numerically highest efficacy (83.6% achieved ≥50% improvement in EASI [EASI-50 response]), followed by abrocitinib 200 mg QD (74.6%), upadacitinib 15 mg QD (70.5%), dupilumab 300 mg every 2 weeks (Q2W) (63.4%) and abrocitinib 100 mg QD (56.7%). Similar trends in EASI-75 and EASI-90 response were observed. In combination therapy RCTs, abrocitinib 200 mg QD had the highest EASI-50 (86.6%), followed by dupilumab 300 mg Q2W (82.4%) and abrocitinib 100 mg QD (79.7%). Similar findings were observed for IGA response and PROs. In monotherapy and combination therapy RCTs, the probability of treatment-emergent adverse events (TEAEs) was higher among all active treatments than with placebo (except for dupilumab 300 mg Q2W [odds ratio (OR), 0.96; 95% credible interval (CrI), 0.45-2.18] and abrocitinib 100 mg QD [OR, 0.95; 95% CrI, 0.35-2.66] in combination therapy RCTs), although active treatments did not significantly differ from one another. Abrocitinib, dupilumab and upadacitinib were consistently the most effective systemic therapies in adult and adolescent patients with AD, with no significant TEAE differences in short-term RCTs.

Lancet 2021; 397:2169-2181. [PMID: 34023009 DOI: 10.1016/s0140-6736(21)00589-4] [Citation(s) in RCA: 182] [Impact Index Per Article: 60.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2020] [Revised: 02/12/2021] [Accepted: 03/02/2021] [Indexed: 12/25/2022]
Abstract
BACKGROUND Systemic therapies are typically combined with topical corticosteroids for the management of moderate-to-severe atopic dermatitis. Upadacitinib is an oral Janus kinase (JAK) inhibitor with greater inhibitory potency for JAK1 than JAK2, JAK3, or tyrosine kinase 2 that is being tested for atopic dermatitis. We aimed to assess the efficacy and safety of upadacitinib plus topical corticosteroids compared with placebo for the treatment of moderate-to-severe atopic dermatitis. METHODS In this randomised, double-blind, placebo-controlled, phase 3 trial (AD Up) adults (aged 18-75 years) and adolescents (aged 12-17 years) with chronic atopic dermatitis that was moderate to severe (≥10% of body surface area affected, Eczema Area and Severity Index [EASI] score of ≥16, validated Investigator's Global Assessment for atopic dermatitis [vIGA-AD] score of ≥3, and weekly average Worst Pruritus Numerical Rating Scale score of ≥4 at baseline) were enrolled at 171 clinical centres across 22 countries in the Asia-Pacific region, Europe, the Middle East, North America, and Oceania. Patients were randomly assigned (1:1:1) to receive upadacitinib 15 mg, upadacitinib 30 mg, or placebo once daily, all in combination with topical corticosteroids for 16 weeks. Randomisation was done using an interactive response technology system, stratified by baseline disease severity, geographical region, and age. Study investigators, study site personnel, and patients were masked to study treatment. The coprimary endpoints were the proportion of patients who had achieved at least a 75% reduction in EASI score from baseline (EASI-75) and the proportion of patients who had achieved a vIGA-AD response (defined as a vIGA-AD score of 0 [clear] or 1 [almost clear] with ≥2 grades of improvement from baseline) at week 16. Efficacy was analysed in the intention-to-treat population and safety was analysed in all patients who received at least one dose of study drug. This study is registered with ClinicalTrials.gov, NCT03568318, and is active, but not recruiting. FINDINGS Between Aug 9, 2018, and Dec 20, 2019, 901 patients were randomly assigned to receive upadacitinib 15 mg plus topical corticosteroids (n=300), upadacitinib 30 mg plus topical corticosteroids (n=297), or placebo plus topical corticosteroids (n=304). At week 16, the proportion of patients who had achieved EASI-75 was significantly higher in the upadacitinib 15 mg plus topical corticosteroid group (194 [65%] of 300 patients) and the upadacitinib 30 mg plus topical corticosteroids group (229 [77%] of 297 patients) than the placebo group (80 [26%] of 304 patients; adjusted difference in EASI-75 response rate vs placebo, 38·1% [95% CI 30·8-45·4] for the upadacitinib 15 mg group and 50·6% [43·8-57·4] for the upadacitinib 30 mg group; p<0·0001 for both doses). The proportion of patients who had achieved a vIGA-AD response at week 16 was significantly higher in the upadacitinib 15 mg plus topical corticosteroid group (119 [40%] patients) and upadacitinib 30 mg plus topical corticosteroid group (174 [59%] patients) than the placebo group (33 [11%] patients; adjusted difference in vIGA-AD response vs placebo, 28·5% [22·1-34·9] for the upadacitinib 15 mg group and 47·6% [41·1-54·0] for the upadacitinib 30 mg group; p<0·0001 for both doses). During the double-blind period, upadacitinib 15 and 30 mg were well tolerated in combination with topical corticosteroids. The most frequently reported treatment-emergent adverse events (≥5% in any treatment group) were acne, nasopharyngitis, upper respiratory tract infection, oral herpes, elevation of blood creatine phosphokinase levels, headache, and atopic dermatitis. The incidence of acne was higher in the upadacitinib 15 mg (30 [10%] of 300 patients) and upadacitinib 30 mg (41 [14%] of 297 patients) groups than the placebo group (six [2%] of 304 patients). The incidence of adverse events leading to discontinuation of study drug (four [1%] patients in the upadacitinib 15 mg plus topical corticosteroids group, four [1%] patients in the upadacitinib 30 mg plus topical corticosteroids group, and seven [2%] patients in the placebo plus topical corticosteroids group) and serious adverse events (seven [2%] patients, four [1%] patients, and nine [3%] patients) were similar among treatment groups. No deaths were reported in any treatment group. INTERPRETATION Upadacitinib plus topical corticosteroids was well tolerated and superior to placebo plus topical corticosteroids. Upadacitinib as combination therapy had a positive benefit-risk profile in adults and adolescents with moderate-to-severe atopic dermatitis. FUNDING AbbVie.

Abstract
Atopic dermatitis (AD) is one of the most common chronic, inflammatory skin disorders with a complex etiology and a broad spectrum of clinical phenotypes. Despite its high prevalence and effect on the quality of life, safe and effective systemic therapies approved for long-term management of AD are limited. A better understanding of the pathogenesis of atopic dermatitis in recent years has contributed to the development of new therapeutic approaches that target specific pathophysiological pathways. Skin barrier dysfunction and immunological abnormalities are critical in the pathogenesis of AD. Recently, the importance of the downregulation of epidermal differentiation complex (EDC) molecules caused by external and internal stimuli has been extensively emphasized. The purpose of this review is to discuss the innovations in the therapy of atopic dermatitis, including biologics, small molecule therapies, and other drugs by highlighting regulatory mechanisms of skin barrier-related molecules, such as filaggrin (FLG) as a crucial pathway implicated in AD pathogenesis.

Abstract
BACKGROUND Upadacitinib is an oral Janus kinase (JAK) inhibitor with greater inhibitory potency for JAK1 than JAK2, JAK3, and tyrosine kinase 2. We aimed to assess the efficacy and safety of upadacitinib compared with placebo for the treatment of moderate-to-severe atopic dermatitis. METHODS Measure Up 1 and Measure Up 2 were replicate multicentre, randomised, double-blind, placebo-controlled, phase 3 trials; Measure Up 1 was done at 151 clinical centres in 24 countries across Europe, North and South America, Oceania, and the Asia-Pacific region; and Measure Up 2 was done at 154 clinical centres in 23 countries across Europe, North America, Oceania, and the Asia-Pacific region. Eligible patients were adolescents (aged 12-17 years) and adults (aged 18-75 years) with moderate-to-severe atopic dermatitis (≥10% of body surface area affected by atopic dermatitis, Eczema Area and Severity Index [EASI] score of ≥16, validated Investigator's Global Assessment for Atopic Dermatitis [vIGA-AD] score of ≥3, and Worst Pruritus Numerical Rating Scale score of ≥4). Patients were randomly assigned (1:1:1) using an interactive response technology system to receive upadacitinib 15 mg, upadacitinib 30 mg, or placebo once daily for 16 weeks, stratified by baseline disease severity, geographical region, and age. Coprimary endpoints were the proportion of patients who had achieved at least a 75% improvement in EASI score from baseline (EASI-75) and the proportion of patients who had achieved a vIGA-AD response (defined as a vIGA-AD score of 0 [clear] or 1 [almost clear] with ≥2 grades of reduction from baseline) at week 16. Efficacy was analysed in the intention-to-treat population and safety was analysed in all randomly assigned patients who received at least one dose of study drug. These trials are registered with ClinicalTrials.gov, NCT03569293 (Measure Up 1) and NCT03607422 (Measure Up 2), and are both active but not recruiting. FINDINGS Between Aug 13, 2018, and Dec 23, 2019, 847 patients were randomly assigned to upadacitinib 15 mg (n=281), upadacitinib 30 mg (n=285), or placebo (n=281) in the Measure Up 1 study. Between July 27, 2018, and Jan 17, 2020, 836 patients were randomly assigned to upadacitinib 15 mg (n=276), upadacitinib 30 mg (n=282), or placebo (n=278) in the Measure Up 2 study. At week 16, the coprimary endpoints were met in both studies (all p<0·0001). The proportion of patients who had achieved EASI-75 at week 16 was significantly higher in the upadacitinib 15 mg (196 [70%] of 281 patients) and upadacitinib 30 mg (227 [80%] of 285 patients) groups than the placebo group (46 [16%] of 281 patients) in Measure Up 1 (adjusted difference in EASI-75 response rate vs placebo, 53·3% [95% CI 46·4-60·2] for the upadacitinib 15 mg group; 63·4% [57·1-69·8] for the upadacitinib 30 mg group) and Measure Up 2 (166 [60%] of 276 patients in the upadacitinib 15 mg group and 206 [73%] of 282 patients in the upadacitinib 30 mg group vs 37 [13%] of 278 patients in the placebo group; adjusted difference in EASI-75 response rate vs placebo, 46·9% [39·9-53·9] for the upadacitinib 15 mg group; 59·6% [53·1-66·2] for the upadacitinib 30 mg group). The proportion of patients who achieved a vIGA-AD response at week 16 was significantly higher in the upadacitinib 15 mg (135 [48%] patients) and upadacitinib 30 mg (177 [62%] patients) groups than the placebo group (24 [8%] patients) in Measure Up 1 (adjusted difference in vIGA-AD response rate vs placebo, 39·8% [33·2-46·4] for the upadacitinib 15 mg group; 53·6% [47·2-60·0] for the upadacitinib 30 mg group) and Measure Up 2 (107 [39%] patients in the upadacitinib 15 mg group and 147 [52%] patients in the upadacitinib 30 mg group vs 13 [5%] patients in the placebo group; adjusted difference in vIGA-AD response rate vs placebo, 34·0% [27·8-40·2] for the upadacitinib 15 mg group; 47·4% [41·0-53·7] for the upadacitinib 30 mg group). Both upadacitinib doses were well tolerated. The incidence of serious adverse events and adverse events leading to study drug discontinuation were similar among groups. The most frequently reported treatment-emergent adverse events were acne (19 [7%] of 281 patients in the upadacitinib 15 mg group, 49 [17%] of 285 patients in the upadacitinib 30 mg group, and six [2%] of 281 patients in the placebo group in Measure Up 1; 35 [13%] of 276 patients in the upadacitinib 15 mg group, 41 [15%] of 282 patients in the upadacitinib 30 mg group, and six [2%] of 278 patients in the placebo group in Measure Up 2), upper respiratory tract infection (25 [9%] patients, 38 [13%] patients, and 20 [7%] patients; 19 [7%] patients, 17 [16%] patients, and 12 [4%] patients), nasopharyngitis (22 [8%] patients, 33 [12%] patients, and 16 [6%] patients; 16 [6%] patients, 18 [6%] patients, and 13 [5%] patients), headache (14 [5%] patients, 19 [7%] patients, and 12 [4%] patients; 18 [7%] patients, 20 [7%] patients, and 11 [4%] patients), elevation in creatine phosphokinase levels (16 [6%] patients, 16 [6%] patients, and seven [3%] patients; nine [3%] patients, 12 [4%] patients, and five [2%] patients), and atopic dermatitis (nine [3%] patients, four [1%] patients, and 26 [9%] patients; eight [3%] patients, four [1%] patients, and 26 [9%] patients).

Abstract
Atopic dermatitis (AD) is a common disease of childhood, and some patients experience a prolonged clinical course into adolescence and adulthood. Systemic management is required when AD is not adequately controlled with topical medications. Our aim is to provide a comprehensive review of commonly used systemic immunomodulating agents in childhood and adult AD, including cyclosporine A (CsA), azathioprine (AZA), methotrexate (MTX) and mycophenolate mofetil (MMF), which are prescribed off-label in the United States, as well as dupilumab, an FDA-approved biologic. We will also provide a brief overview of emerging systemic therapies currently under investigation.

Abstract
The European Journal of Immunology was launched 50 years ago, coinciding with the discovery of many cytokines and growth factors and the emergence of an entirely new field of research. Ultimately, our knowledge about the biological activity of these factors allowed us to better understand how the immune system functions in the context of inflammatory and autoimmune diseases leading to the development of targeted biologic therapies. The study of cytokine signal transduction led to the discovery of Janus kinases (JAK), and the consideration of therapeutically targeting JAKs to treat immune and inflammatory diseases. This year also marks the tenth anniversary of the approval of the first JAK inhibitor (jakinib) and now there are a total of nine approved jakinibs for treatment of rheumatologic, dermatologic, gastrointestinal, and neoplastic indications and most recently COVID-19. Here, we summarized the discoveries that led to development of first-generation jakinibs, discussed some of the newer, possibly more selective jakinibs, as well as jakinibs that also target other kinases. We also illustrated the rationale behind the application of these drugs in the treatment of COVID-19 cytokine storm. In this review, we will discuss the clinical success of jakinibs, the gaps in our understanding of their biological activities as well as challenges in regard to their clinical application.

Abstract
The evolving discoveries in atopic dermatitis (AD) broaden our understanding of the pathogenesis of the disease and, above all, enable better management for patients. Dupilumab was the first biologic for AD, and since its approval, many new treatments have emerged in both late- and early-stage clinical trials. These trials have led to a further understanding of the pathogenesis of AD and to the identification of additional potential therapeutic targets. This review will highlight the emerging therapies and provide approaches on how to choose the right treatment for your patients.

Abstract
Atopic dermatitis is a common, chronic inflammatory skin disorder, present in about 12% of children worldwide. Optimizing management of severe atopic dermatitis in pediatric patients is critical to reduce signs of inflammation, alleviate pruritus and sleep disturbance, minimize the development and/or impact of comorbidities, and improve the patient and caregiver's quality of life. Evaluating the longitudinal severity of pediatric atopic dermatitis is an important component of measuring therapeutic response and long-term management, and is different in clinical practice versus clinical trials. This article describes when and how to use different treatments for pediatric patients with severe atopic dermatitis, including topical medications, phototherapy, and systemic medical therapies (traditional immunosuppressants, biologics, and small molecule inhibitors). It also provides recommendations useful in clinical practice for nonpharmacologic interventions for pediatric patients with severe atopic dermatitis.

Abstract
Dermatologists' interest in the Janus-associated kinase (JAK)/signal transducers and activators of transcription (STAT) pathway has been growing as evidence builds to support its key role in the pathogenesis of inflammatory skin diseases. Because certain proinflammatory cytokines use the JAK/STAT pathway for signal transduction, it has become a promising therapeutic target in diseases where selective modulation of the immune system can be useful. We aim to review current knowledge of the JAK/STAT signaling pathway and its role in immune-mediated skin diseases. In the second part of the review we cover the efficacy and safety of oral and topical JAK inhibitors in the treatment of psoriasis, atopic dermatitis, and other skin diseases.

Abstract
Atopic dermatitis (AD) is among the most frequent inflammatory skin diseases in humans, affecting up to 20% of children and 10% of adults in higher income countries. Chronic pruritus is a disease-defining symptom of AD, representing the most burdensome symptom for patients. Severe chronic pruritus causes significant sleep disturbances and impaired quality of life, as well as increased anxiety, depression and suicidal behavior. Until recently, skin care, topical corticosteroids, and calcineurin-inhibitors were primarily used to treat mild to moderate AD, while phototherapy and immunosuppressive agents such as corticosteroids, cyclosporine, and methotrexate were used to treat patients with moderate to severe AD. The potential short- and long-term adverse events associated with these treatments or their insufficient therapeutic efficacy limited their use in controlling pruritus and eczema in AD patients over longer periods of time. As our understanding of AD pathophysiology has improved and new systemic and topical treatments have appeared on the market, targeting specific cytokines, receptors, or their intracellular signaling, a new era in atopic dermatitis and pruritus therapy has begun. This review highlights new developments in AD treatment, placing a specific focus on their anti-pruritic effects.

Abstract
Atopic dermatitis (AD) is a common inflammatory skin disease characterised by itch and is responsible for significant reduction in quality of life. While AD primarily arises in those under the age of 2 years, it is frequently persistent into adulthood. Recognition of AD is important for the general physician, especially to distinguish causes of acute flares that may present in any medical setting, such as eczema herpeticum and associated allergic reactions. While, to date, treatments have largely focused on broad spectrum immunomodulation with corticosteroids or systemic therapies (such as ciclosporin and methotrexate), increased knowledge in the pathophysiology of the disease has recently led to the expansion of treatment options available for those suffering with AD, and the new drugs on the horizon promise a previously unimagined potential for effective and safe treatment.
