Janus kinase (JAK) inhibitors are promising treatments for atopic dermatitis (AD). The aim of this study was to assess the efficacy and safety of JAK inhibitors for AD treatment via the "Grading of Recommendations Assessment, Development, and Evaluation" approach. We identified 15 randomized controlled trials comparing oral or topical JAK inhibitors against placebo to treat AD. A random-effects meta-analysis was performed, and the numbers-needed-to-treat (NNTs)/numbers-needed-to-harm (NNHs) were ...[more]

Project description:BackgroundClinicians and healthcare policymakers have been drenched with a deluge of overlapping meta-analyses (MAs), and the necessity for comprehensive and clearly defined evidence of Janus kinase inhibitors (JKIs) in atopic dermatitis (AD) is urgent.MethodsSix databases were searched for MAs published until October 2023. Qualitative description of MAs was mainly used, and Investigator's Global Assessment response (IGA response), the 75% improvement in Eczema Area and Severity Index (the EASI75), peak pruritus Numerical rating score (PP-NRS), and adverse effects were cited to describe the efficacy and safety of JKIs. The methodological quality of the included MAs was assessed by A Measurement Tool to Assess Systematic Reviews II (AMSTAR II), and the quality of evidence was evaluated by the grading of recommendations, assessment, development, and evaluation (GRADE).ResultsSixteen MAs were pooled in this review, of which five studies appraised JKIs, five appraised systemic JKIs, five papers assessed abrocitinib only, and one assessed baricitinib. Two studies were of "high" methodological quality and 14 MAs were of "moderate" quality. Eleven MAs integrated the results of JKIs and reported that JKIs provide faster onset of IGA response (RR=2.83, 95% CI [2.25, 3.56], high-quality evidence). Similarly, 10 MAs showed that JAK inhibitors were more effective in improving the EASI75 (RR=2.84, 95% CI [2.2, 3.67], high-quality evidence). Results from 12 MAs showed JKIs were active in reducing the PP-NRS (SMD=-0.49, 95% CI [-0.67, -0.32]). All MAs affirmed JKIs added no adverse effects leading to discontinuation and serious adverse events (P<0.05). However, 200mg of abrocitinib had a higher risk of acne (RR=4.34, 95% CI [1.61, 11.71), herpes zoster (RR=1.64, 95% CI [0.42, 6.39]), headache (RR=1.76, 95% CI [1.03, 3]), and nausea (RR=7.81, 95% CI [3.84, 15.87]). Upadacitinib was known to increase acne (RR=6.23, 95% CI [4.08, 9.49]), nasopharyngitis (RR=1.36, 95% CI [1.03, 1.8]) and blood creatine phosphokinase (blood CPK) (RR=2.41, 95% CI [1.47, 3.95]). Baricitinib at 2mg was associated with increased blood CPK (RR=2.25, 95% CI [1.1, 2.97]).ConclusionCompared to placebo or dupilumab, the administration of JKIs can ameliorate IGA response more effectively, improve the EASI75, and relieve pruritus without severe adverse effect, while accompanied by more acne, nasopharyngitis, headache, and digestive disturbances. The curative effect of 200 mg of abrocitinib is significant and more caution should be given in patients with gastrointestinal dysfunction, herpes zoster, and those who are acne-prone. Baricitinib and upadacitinib should be avoided in populations at high risk for cardiovascular events.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?RecordID=369369, PROSPERO (CRD42022369369).

Project description:BackgroundTopical Janus kinase (JAK) inhibitors are being developed for the treatment of mild to moderate atopic dermatitis. However, comparative evidence on their safety profiles is still limited.AimThis study aimed to compare the relative safety of topic JAK inhibitors in patients with atopic dermatitis.MethodPhase 2 and 3 clinical trials (RCTs) evaluating the efficacy and safety of topical JAK inhibitors in atopic dermatitis were searched on Medline, EMBASE and clinicaltrials.gov. The following outcomes were considered: any adverse event (AE), serious AEs, AEs leading to treatment discontinuation, any infection, any application site reaction.ResultsTen RCTs were included in this network meta-analysis. Tofacitinib was associated with a reduced risk of any AE when compared with ruxolitinib (OR 0.18, 95% CrI 0.03-0.92). The analyses for the remaining outcomes did not identify other statistically significant risk differences between the topical JAK inhibitors.ConclusionAlthough tofacitinib seems to present a reduced risk of any adverse event compared with ruxolitinib, this was the only statistically significant result found between JAK inhibitors. Therefore, such findings should be interpreted with caution considering the scarce data available and the heterogeneity between the studies, and there is no robust evidence allowing pointing out clinically important differences between the safety profiles of the existing topical JAK inhibitors. Further pharmacovigilance activities are needed to confirm the safety profile of these drugs.

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:BackgroundIn recent years, biologics targeting key cytokines and Janus kinase (JAK) inhibitors have demonstrated favorable efficacy and safety outcomes for atopic dermatitis (AD) therapy. To evaluate the short-term efficacy and safety of AD therapy involving biologics, JAK inhibitors, and their combination with topical corticosteroids (TCS) for patients with AD, we conducted this systematic review and meta-analysis. Using eligible randomized clinical trials (RCTs) of 12 or 16 weeks of treatment with systemic medications and 4 weeks of topical treatment for AD.MethodsPubMed, Web of Science, ScienceDirect, and the Cochrane Library were searched from inception up to October 25, 2023. English-language randomized clinical trials (RCTs) of 12 or 16 weeks of treatment with systemic medications and 4 weeks of topical treatment for AD were included. Titles, abstracts, and articles were screened in duplicate. Of 7261 citations, 37 studies were included. The data were analyzed using Review Manager 5.4 and the outcomes were measured by the Eczema Area and Severity Index (EASI), Investigator Global Assessment (IGA), the pruritus Numerical Rating Scale (NRS), as well as instances of adverse events (AE), and serious AE (SAE), which were presented as risk ratio (RR) with a 95 % confidence interval (CI). The efficacy of the biological therapies was analyzed with the percentage of patients who have achieved EASI 75, EASI 90, IGA 0/1 and pruritus NRS4, while the safety of treatments was evaluated in terms of the number of patients who had ≥1 AE and who had at least one SAE.ResultsA total of 37 studies with 43 cohorts that examined 9 medications and placebo and involved 18172 participants were included. Compared with the placebo, all biologics and JAK inhibitors were associated with a higher response rate in efficacy outcomes, while systematic administration was presented by dupilumab 200 mg subcutaneously every 2 weeks with superior improvement in EASI 90 (RR 9.50, 95 % CI 2.31-39.03) and IGA0/1 (RR 17.00, 95 % CI 2.33-123.78), upadacitinib 30 mg once daily in EASI 75 (RR 5.14, 95 % CI 4.20-6.31) and Pruritus NRS4 (RR 5.73, 95 % CI 4.44-7.39), and external use was presented by ruxolitinib 1.5 % twice daily orally in EASI 75 (RR 4.14, 95 % CI 3.06-5.61) and Pruritus NRS4 (RR 4.08, 95 % CI 2.86-5.81), and most of doses led to a better safety profile. Most doses of baricitinib, dupilumab, tralokinumab, and upadacitinib in combination with TCS demonstrated good efficacy as compared with the control groups (placebo + TCS). However, patients receiving baricitinib at a dosage of 2 mg daily (RR 1.23, 95 % CI 1.02-1.49) and 4 mg daily (RR 1.39, 95 % CI 1.22-1.58) in combination with TCS, exhibited a higher incidence of one or more SAE as compared with those taking placebo + TCS.ConclusionOur research has revealed that ruxolitinib and dupilumab are effective and safe treatments for mild to moderate AD and moderate to severe AD, respectively. Additionally, the combination of dupilumab and TCS demonstrates greater efficacy and safety compared to baricitinib, tralokinumab, and upadacitinib with TCS as a background treatment for moderate to severe AD. We suggest that the use of topical JAK inhibitors could be a potential alternative to TCS when used in combination with systemic medications, as a novel approach to treat AD. Insufficient different data sources caused by partial interventions were only mentioned in a few articles and low event rates in safety analyses may lead to the results being biased. Further studies directly comparing existing and novel treatments are needed and will be included in forthcoming updates of this review. Our findings could form a useful foundation for developing a new generation of treatment guidelines for AD.

Project description:ImportanceThe risk of venous thromboembolism (VTE) among patients with atopic dermatitis (AD), especially when receiving treatment with Janus kinase (JAK) inhibitors, is unclear.ObjectiveTo determine the association of AD with incident VTE and evaluate the risk of incident VTE among patients with AD who were receiving treatment with JAK inhibitors.Data sourcesThe MEDLINE, Embase, Cochrane Library, and Web of Science databases were searched with no restrictions on language nor geographic locations from their respective inception to February 5, 2022.Study selectionCohort studies examining the association of AD with incident VTE and randomized clinical trials (RCTs) reporting VTE events in participants with AD receiving JAK inhibitors were included. Around 0.7% of initially identified articles met the selection criteria.Data extraction and synthesisThe Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed. The risk of bias of included cohort studies and RCTs was assessed by the Newcastle-Ottawa Scale and the Cochrane Risk of Bias Tool 2, respectively. A random-effects model meta-analysis was conducted to calculate the pooled hazard ratio (HR) and risk difference for incident VTE.Main outcomes and measuresThe HRs for incident VTE associated with AD and risk difference for incident VTE between participants with AD who were receiving treatment with JAK inhibitors and controls receiving placebo or dupilumab.ResultsTwo cohort studies and 15 RCTs with a total of 466 993 participants were included. The meta-analysis found no significant association of AD with incident VTE (HR, 0.95; 95% CI 0.62-1.45; incidence rate of VTE, 0.23 events/100 patient-years). Overall, 3 of 5722 patients with AD (0.05%) who were receiving treatment with JAK inhibitors experienced VTE compared with 1 of 3065 patients with AD (0.03%) receiving placebo or dupilumab (Mantel-Haenszel risk difference, 0; 95% CI, 0-0). The incidence rate of VTE was 0.15 and 0.12 events per 100 patient-years in participants with AD receiving JAK inhibitors and placebo, respectively. The findings were similar in 4 unique JAK inhibitors (abrocitinib, baricitinib, upadacitinib, and SHR0302).Conclusions and relevanceThe results of this systematic review and meta-analysis suggest that the currently available evidence does not detect an increased risk of VTE associated with AD or treatment with JAK inhibitors. These findings may provide a reference for clinicians in prescribing JAK inhibitors for patients with AD.

Project description: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:IntroductionAtopic dermatitis (AD) is a chronic inflammatory skin disease with multifactorial pathophysiology. Biologic therapies, including dupilumab (IL-4/IL-13 inhibitor) and tralokinumab (IL-13 inhibitor), as well as selective Janus kinase-1 (JAK-1) inhibitors such as upadacitinib and abrocitinib, have been approved for the treatment of moderate to severe AD. However, their association with the incidence of malignancy in AD patients remains uncertain.AimWe conducted a systematic review and network meta-analysis (NMA) to investigate and compare the indidence and risk of malignancy in individuals with moderate-to-severe AD treated with abrocitinib, upadacitinib, tralokinumab, or dupilumab.Material and methodsSystematic searches were conducted in Ovid MEDLINE and EMBASE that included AD, malignancy, biologic and advanced therapies. The primary outcome was incidence of malignancy in AD patients receiving placebo or at least one of the following advanced therapies: dupilumab, tralokinumab, abrocitinib or upadacitinib. A random-effects NMA was conducted with odds ratios and a frequentist model.ResultsOur search identified 11 trials comprising 10097 patients. The NMA did not show any statistically significant association between dupilumab or selective JAK-1 inhibitors and the incidence of malignancy up to an average of 41 weeks of treatment.ConclusionsOur analysis revealed no statistically significant increased risk of malignancy and no significant difference in the incidence of malignancy between selective JAK-1 inhibitors and dupilumab for the treatment of AD up to an average follow-up of 41 weeks. Nevertheless, further prospective studies with longer follow-up periods are warranted to confirm the safety of these therapies and their impact on the risk of malignancy.

Project description: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.

Project description:ObjectivesThis study investigated the clinical efficacy and safety of oral Janus kinase inhibitors (JAKis) in the treatment of hospitalized patients with COVID-19.MethodsThe PubMed, Embase, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov databases were searched for relevant articles written before January 29, 2022. Only randomized controlled trials (RCTs) that assessed the clinical efficacy and safety of oral JAKis in patients with COVID-19 were included.ResultsIn the pooled analysis of the 7 RCTs, the all-cause 28-day mortality rate in the study group receiving JAKis was significantly lower than that in the control group (9.4% [183/1941] vs. 10.9% [184/1687], risk ratio [RR] = 0.69, 95% confidence interval [CI], 0.58-0.81, I2 = 0%). In addition, the risk of 14-day mortality was in the study group was lower than that in the control group (RR = 0.65, 95% CI, 0.46-0.92, I2 = 0%). Finally, the study group and the control group exhibited similar risks of any adverse events (RR = 0.96, 95% CI, 0.89-1.04, I2 = 0%).ConclusionsOral JAKis can significantly reduce the risk of death among patients with COVID-19. In addition, JAKis are tolerable for hospitalized patients with COVID-19.

Project description:Importance:Topical medication is the central treatment for patients with atopic dermatitis (AD), but the options are limited. Phosphodiesterase 4 (PDE4) inhibitors are a new candidate for AD therapy. Objective:To evaluate the efficacy and safety of topical PDE4 inhibitors in mild to moderate AD. Data Sources:Clinical trials were identified from MEDLINE, Embase, Cochrane Controlled Register of Trials, Chinese medical databases (Wanfang, Chinese National Knowledge Infrastructure, Chinese Biomedical Literature Database, and China Science and Technology Journal Database), ClinicalTrials.gov, and other trial registries from inception to August 15, 2018. No restrictions on languages were placed. Study Selection:Only double-blind randomized clinical trials with topical PDE4 inhibitors vs topical vehicle treatment for patients with mild to moderate AD were included. Data Extraction and Synthesis:Two reviewers independently extracted study features, intervention details, and outcomes. A meta-analysis was performed using the random-effects model. The Cochrane Collaboration's risk of bias assessment tool was used to assess the risk of bias. Funnel plots and Egger tests were used to assess the publication bias. Main Outcomes and Measures:Changes from baseline in target lesion score were expressed in terms of standardized mean differences (SMDs) with 95% CIs. Outcomes of investigators' assessment and safety were expressed in terms of relative risk with 95% CIs. Results:Seven studies were identified, which included 1869 patients with mild to moderate AD. Overall, compared with the topical vehicle control, topical application of PDE4 inhibitors was associated with a significant decrease in target lesion score (SMD -0.40; 95% CI, -0.61 to -0.18; P < .001) and a higher response rate in investigators' assessment of clear or almost clear skin (relative risk, 1.50; 95% CI, 1.33-1.70; P < .001). There was no difference in treatment-related adverse events or in adverse events that required discontinuation of therapy. Subgroup analyses indicated that after 14 and 28 days of therapy with PDE4 inhibitors, target lesion score was significantly decreased. However, these beneficial effects were displayed only for the PDE4 inhibitors crisaborole and AN2898 (crisaborole at day 14: SMD, -0.59; 95% CI, -1.15 to -0.02; P = .04; AN2898 at day 14: SMD, -0.76; 95% CI, -1.38 to -0.13; P = .02; crisaborole at day 28: SMD, -0.86; 95% CI, -1.44 to -0.28; P = .004; AN2898 at day 28: SMD, -0.68; 95% CI, -1.30 to -0.05; P = .03). Heterogeneity was not significant across studies. Conclusions and Relevance:This meta-analysis suggests that topical PDE4 inhibitors are a safe and effective treatment for mild to moderate AD. Current evidence supports the use of crisaborole or AN2898 as the choice of maintenance or sequential therapy for mild to moderate AD.
