Systematic Review on the Efficacy and Safety of Oral Janus Kinase Inhibitors for the Treatment of Atopic Dermatitis.

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.

Project description:BackgroundCurrent therapeutic options for atopic dermatitis (AD) are limited. Janus kinase (JAK) inhibitors may be viable alternatives.ObjectivesTo assess the efficacy and safety of JAK inhibitors for AD treatment.MethodsWe 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.ResultsWe 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).ConclusionOur 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.

Project description:ImportanceAtopic dermatitis is associated with substantial patient and caregiver burden. Currently available treatments for atopic dermatitis are inadequate or contraindicated for some patients. Abrocitinib (PF-04965842) is an oral Janus kinase 1 selective inhibitor under investigation for the treatment of atopic dermatitis.ObjectiveTo investigate the efficacy and safety of abrocitinib for patients with moderate to severe atopic dermatitis.Design, setting, and participantsA phase 2b, randomized, double-blinded, placebo-controlled, parallel-group trial was conducted from April 15, 2016, to April 4, 2017, at 58 centers in Australia, Canada, Germany, Hungary, and the United States among 267 patients 18 to 75 years of age with a clinical diagnosis of moderate to severe atopic dermatitis for 1 year or more and inadequate response or contraindication to topical medications for 4 weeks or more within 12 months. Efficacy was assessed in the full analysis set, which was a modified intention-to-treat population that included all patients who received 1 dose or more of the study drug except for 4 patients from 1 site.InterventionsParticipants were randomly assigned 1:1:1:1:1 to receive abrocitinib (200 mg, 100 mg, 30 mg, or 10 mg) or placebo once daily for 12 weeks.Main outcomes and measuresThe primary outcome was the proportion of patients achieving an Investigator's Global Assessment of clear (0) or almost clear (1) with an improvement from baseline of 2 grades or more at week 12. The secondary outcome was the percentage change from baseline in the Eczema Area and Severity Index at week 12.ResultsOf the 267 participants, 144 were women (mean [SD] age, 40.8 [16.1] years). At week 12, 21 of 48 patients receiving 200 mg of abrocitinib (43.8%; P < .001, 2-sided), 16 of 54 patients receiving 100 mg of abrocitinib (29.6%; P < .001), and 3 of 52 patients receiving placebo (5.8%) achieved grades of clear or almost clear on the Investigator's Global Assessment scale with improvement of 2 grades or more; these rates correspond to maximum effect model-based estimates of 44.5% (95% CI, 26.7%-62.3%) for those receiving 200 mg of abrocitinib, 27.8% (95% CI, 14.8%-40.9%) for those receiving 100 mg of abrocitinib, and 6.3% (95% CI, -0.2% to 12.9%) for those receiving placebo. Reductions in the Eczema Area and Severity Index were 82.6% (90% CI, 72.4%-92.8%; P < .001) for those receiving 200 mg of abrocitinib, 59.0% (90% CI, 48.8%-69.3%; P = .009) for those receiving 100 mg of abrocitinib, and 35.2% (90% CI, 24.4%-46.1%) for those receiving placebo. Adverse events were observed in 184 of 267 patients (68.9%); the most frequently reported adverse events (in ≥3 patients in any group) were dermatitis atopic, upper respiratory tract infection, headache, nausea, and diarrhea. Dose-dependent decreases in platelet count were observed but trended upward toward baseline levels after week 4.Conclusions and relevanceOnce-daily oral abrocitinib was effective and well tolerated for short-term use in adults with moderate to severe atopic dermatitis. Additional trials are necessary to evaluate long-term efficacy and safety.Trial registrationClinicalTrials.gov identifier: NCT02780167.

Project description:BackgroundAtopic 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.ObjectiveThe aim of this study was to investigate the efficacy and safety of SHR0302 in Chinese patients with moderate to severe atopic dermatitis.Design and settingA randomized, double-blind, placebo-controlled, multicenter, phase II trial was conducted in China between October 2019 and August 2020.ParticipantsPatients (n = 105) aged 18-75 years with moderate to severe dermatitis and nonresponsive or intolerant to topical or conventional systemic treatments were included.InterventionsPatients 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 measuresThe 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.ResultsAt 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 relevanceOral SHR0302 was effective and well tolerated in Chinese adult patients with moderate to severe atopic dermatitis.Trial registrationClinicalTrials.gov identifier: NCT04162899; URL: https://clinicaltrials.gov/ .
