Meta-Analysis
BACKGROUND
Janus kinase (JAK) inhibitors and secukinumab have been demonstrated to be effective treatments for ankylosing spondylitis (AS). However, there have been no head-to-head trials comparing the effectiveness and safety characteristics of JAK inhibitors with secukinumab. This study aimed to evaluate the relative effectiveness and safety of JAK inhibitors and secukinumab in patients with active AS.
SUMMARY
A Bayesian network meta-analysis was conducted using direct and indirect data from randomized controlled trials (RCTs) that examined the efficacy and safety of tofacitinib 5 mg, upadacitinib 15 mg, filgotinib 200 mg, and secukinumab 150 mg in patients with active AS who had a poor response or intolerance to nonsteroidal anti-inflammatory drugs (NSAIDs) and were tumor necrosis factor (TNF) inhibitor-naïve. Data from six RCTs comprising 937 patients were analyzed. The Assessment of SpondyloArthritis International Society 20 (ASAS20) response rates were significantly higher in the JAK inhibitors and secukinumab groups than in the placebo group. The surface under the cumulative ranking curve (SUCRA)-based ranking probability based on the ASAS20 response rate suggested that tofacitinib 5 mg had the highest likelihood of being the best treatment for achieving the ASAS20 response rate, followed by filgotinib 200 mg, upadacitinib 15 mg, secukinumab 150 mg, and placebo. The SUCRA-based ranking probability based on the ASAS20 response rate suggested that tofacitinib 5 mg had the highest likelihood of being the best treatment for achieving the ASAS40 response rate, followed by upadacitinib 15 mg, secukinumab 150 mg, filgotinib 200 mg, and placebo.
KEY MESSAGES
Tofacitinib 5 mg was the most effective treatment for AS, whereas JAK inhibitors and secukinumab 150 mg were effective treatments in patients with active AS who had a poor response or intolerance to NSAIDs and were TNF inhibitor-naïve.

Review
BACKGROUND
Systemic sclerosis (SSc) is a systemic autoimmune disease with heterogeneous clinical presentation and prognosis. JAK inhibitors reduced cutaneous and pulmonary fibrosis in mice models of SSc. Clinical data regarding the efficacy and safety of JAK inhibitors in SSc patients are scarce.
METHODS
We performed a systematic literature review of patients with SSc defined by the 2013 ACR/EULAR criteria and treated with JAK inhibitors, searching in Medline, Cochrane library and Embase databases.
RESULTS
Fifty-nine patients (mean age 47 ± 15 years) were included. Median treatment duration was 12 [6-12] months. JAK inhibitors (tofacitinib in 47 patients and baricitinib in 12 patients) were prescribed as first line therapy in 35 patients (59%). A significant cutaneous response (decrease in the mRSS - modified Rodnan skin score - of >5 points and ≥ 25% from baseline) was reported in 52 patients (88%). Among patients with interstitial lung disease (ILD) (n = 31), 28/29 patients had no ILD progression during follow-up time (missing data in 2 patients). Only 2 patients had a disease progression during treatment (including one patient with progressive skin fibrosis). Cutaneous response was more frequently observed in treatment naïve SSc patients. Decrease of the mRSS after treatment initiation was more significant in treatment naïve SSc patients. Eighteen non-serious side-effects were noted in 12 patients (20%), without treatment interruption: 6 infections, 6 gastrointestinal disorders, 4 hepatitis and 3 dyslipidemias.
CONCLUSION
JAK inhibitors could represent a safe and effective treatment option for skin fibrosis and ILD in systemic sclerosis.

Due to the lack of comprehensive evidence based on prospective studies, the efficacy and safety of Janus Kinase (JAK) inhibitors (including tofacitinib, ruxolitinib, baricitinib, ritlecitinib and brepocitinib) for alopecia areata (AA) are yet to be proved. The systematic review and meta-analysis was performed pursuant to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guideline and registered on PROSPERO (CRD42022303007). Fourteen prospective studies (5 RCTs and 9 non-RCTs), enrolling a total of 1845 patients with AA, were included for quantitative analysis. In RCTs, oral JAK inhibitors resulted in higher good response rate compared with control (RR: 6.86, 95% CI: 2.91-16.16); topical JAK inhibitors did not show any difference compared with control (RR: 1.00, 95% CI: 0.31-3.18). In non-RCTs, the pooled rate of good response to oral, topical and sublingual JAK inhibitors were 63% (95% CI: 44%-80%), 28% (95% CI: 1%-72%) and 11% (95% CI: 1%-29%), respectively. The pooled recurrence rate in patients treated with JAK inhibitors was 54% (95% CI: 39%-69%), mainly due to the withdrawal of JAK inhibitors. In RCTs, no difference was found in the risk of experiencing most kind of adverse events; in non-RCTs, the reported adverse events with high incidence rate were mostly mild and manageable. JAK inhibitors are efficacious and generally well-tolerated in treating AA with oral administration, whereas topical or sublingual administration lacks efficacy. Subgroup analyses indicate that baricitinib, ritlecitinib and brepocitinib seem to have equal efficacy for AA in RCTs; ruxolitinib (vs. tofacitinib) and AA (vs. AT/AU) are associated with better efficacy outcomes in non-RCT. Due to the high recurrence rate after withdrawal of JAK inhibitors, continuous treatment should be considered to maintain efficacy. PROSPERO: CRD 42022303007.

Meta-Analysis
Comparative efficacy and safety of JAK inhibitors as monotherapy and in combination with methotrexate in patients with active rheumatoid arthritis: A systematic review and meta-analysis.
BACKGROUND
We aim to evaluate the efficacy and tolerability of Janus kinase inhibitors (JAKi) as monotherapy and in combination with methotrexate (MTX) in active rheumatoid arthritis (RA).
METHODS
Medline, EMBASE, and Cochrane Library were systematically searched to identify relevant randomized controlled trials (RCTs). Pooled analysis was conducted using random-effects model, along with the risk difference (RD) and 95% confidence intervals (CIs).
RESULTS
Three RCTs, including 2,290 patients, were included. JAKi (tofacitinib, baricitinib, and filgotinib) plus MTX displayed a higher proportion of patients meeting the American College of Rheumatology (ACR) criteria than JAKi alone at week 52 (ACR20 RD 0.032; 95% CI -0.027 to 0.091; ACR50 RD 0.050; 95% CI 0.003 to 0.097; ACR70 RD 0.056; 95% CI 0.012 to 0.100). Similar results were observed for ACR20/50/70 at week 24. No significant difference was found between two regimens for the proportion of patients achieving Health Assessment Questionnaire disability index (HAQ-DI) improvement ≥ 0.22 at weeks 24 and 52. Regarding low disease activity and remission achievement, JAKi in combination with MTX, contributed higher response rates than JAKi alone at weeks 24 and 52. Compared with JAKi monotherapy, combination therapy had a higher risks of treatment-emergent adverse events (TEAEs) and adverse events (AEs) leading to study discontinuation.
CONCLUSION
JAKi combined with MTX demonstrated superiority to JAKi monotherapy in terms of ACR responses, low disease activity and remission achievement. The two regimens presented comparable physical functioning measured by HAQ-DI improvement and similar tolerability, except for high risks of TEAEs and AEs leading to study discontinuation in combination therapy.

Meta-Analysis
INTRODUCTION
Rapidity of symptom resolution informs treatment choice in patients with moderate-severe ulcerative colitis (UC). We conducted a systematic review and network meta-analysis comparing early symptomatic remission with approved therapies.
METHODS
Through a systematic literature review to December 31, 2022, we identified randomized trials in adult outpatients with moderate-severe UC treated with approved therapies (tumor necrosis factor α antagonists, vedolizumab, ustekinumab, janus kinase inhibitors, or ozanimod), compared with each other or placebo, reporting rates of symptomatic remission (based on partial Mayo score, with resolution of rectal bleeding and near-normalization of stool frequency) at weeks 2, 4, and/or 6. We performed random-effects network meta-analysis using a frequentist approach and estimated relative risk (RR) and 95% confidence interval values.
RESULTS
On network meta-analysis, upadacitinib was more effective than all agents in achieving symptomatic remission at weeks 2 (range of RR, 2.85-6.27), 4 (range of RR, 1.78-2.37), and 6 (range of RR, 1.84-2.79). Tumor necrosis factor α antagonists and filgotinib, but not ustekinumab and vedolizumab, were more effective than ozanimod in achieving symptomatic remission at week 2, but not at weeks 4 and 6. With approximately 10% placebo-treated patients achieving symptomatic remission at 2 weeks, we estimated 68%, 22%, 23.7%, 23.9%, 22.2%, 18.4%, 15.7%, and 10.9% of upadacitinib-, filgotinib-, infliximab-, adalimumab-, golimumab-, ustekinumab-, vedolizumab-, and ozanimod-treated patients would achieve early symptomatic remission, ustekinumab and vedolizumab achieving rapid remission only in biologic-naïve patients.
DISCUSSION
In a systematic review and network meta-analysis, upadacitinib was most effective in achieving early symptomatic remission, whereas ozanimod was relatively slower acting.

Review
Management options for moderate-to-severe alopecia areata (AA) are limited owing to a lack of safe and effective treatments suitable for long-term use. However, newer agents have the potential to induce and maintain hair regrowth in patients with a better side-effects profile compared to systemic steroids or conventional systemic agents. In this article, we conducted a systematic review of newer agents, including Janus kinase (JAK) inhibitors, biologics and phosphodiesterase-4 (PDE-4) inhibitors, for the treatment of AA in adult patients evaluated in randomized controlled trials (RCTs) using the Severity of Alopecia Tool score. A literature search was performed on PubMed and ClinicalTrials.gov, which identified 106 items with 12 RCTs eligible for review. Information regarding the treatment regimen, duration, endpoints, efficacy and adverse events were extracted; product monograph information was also summarized for approved agents with or without indications for AA. Overall, current data suggest the oral JAK inhibitors (baricitinib, ritlecitinib, deuruxolitinib, brepocitinib) as a promising new class of agents that can induce significant hair regrowth, with mild to moderate adverse effects. Baricitinib recently received US FDA approval for the treatment of severe AA, while ritlecitinib and deuruxolitinib have received the breakthrough therapy designation for AA. In contrast, PDE-4 inhibitors (apremilast) and the biologics (dupilumab, secukinumab and aldesleukin) appear to have limited efficacy thus far. Results from ongoing and future long-term studies could shed light on the utility of the newer agents in altering the progression of AA.

Meta-Analysis
BACKGROUND & AIMS
Inhibitors of Janus kinases (JAKs) are being developed for treatment of inflammatory bowel diseases and other immune-mediated diseases. Tofacitinib is effective in treatment of ulcerative colitis, but there are safety concerns. We performed a systematic review and meta-analysis to investigate the safety profile of tofacitinib, upadacitinib, filgotinib, and baricitinib in patients with rheumatoid arthritis, inflammatory bowel diseases, psoriasis, or ankylosing spondylitis.
METHODS
We searched the MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials from January 1, 1990, through July 1, 2019. We performed a manual review of conference databases from 2012 through 2018. The primary outcome was incidence rates of adverse events (AEs) and serious AEs. We also estimated incidence rates of serious infections, herpes zoster infection, non-melanoma skin cancer, other malignancies, major cardiovascular events, venous thromboembolism, and mortality. We performed a meta-analysis, which included controlled studies, to assess the relative risk of these events.
RESULTS
We identified 973 studies; of these, 82 were included in the final analysis, comprising 66,159 patients with immune-mediated diseases who were exposed to a JAK inhibitor. Two-thirds of the included studies were randomized controlled trials. The incidence rate of AEs was 42.65 per 100 person-years and of serious AEs was 9.88 per 100 person-years. Incidence rates of serious infections, herpes zoster infection, malignancy, and major cardiovascular events were 2.81 per 100 person-years, 2.67 per 100 person-years, 0.89 per 100 person-years, and 0.48 per 100 person-years, respectively. Mortality was not increased in patients treated with JAK inhibitors compared with patients given placebo or active comparator (relative risk 0.72; 95% confidence interval 0.40-1.28). The meta-analysis showed a significant increase in risk of herpes zoster infection among patients who received JAK inhibitors (relative risk 1.57; 95% confidence interval 1.04-2.37).
CONCLUSIONS
In a systematic review and meta-analysis, we found an increased risk of herpes zoster infection among patients with immune-mediated diseases treated with JAK inhibitors. All other AEs were not increased among patients treated with JAK inhibitors.

Comparative Study
OBJECTIVE
To compare the effects of treatments for coronavirus disease 2019 (covid-19).
DESIGN
Living systematic review and network meta-analysis.
DATA SOURCES
WHO covid-19 database, a comprehensive multilingual source of global covid-19 literature, up to 3 December 2021 and six additional Chinese databases up to 20 February 2021. Studies identified as of 1 December 2021 were included in the analysis.
STUDY SELECTION
Randomised clinical trials in which people with suspected, probable, or confirmed covid-19 were randomised to drug treatment or to standard care or placebo. Pairs of reviewers independently screened potentially eligible articles.
METHODS
After duplicate data abstraction, a bayesian network meta-analysis was conducted. Risk of bias of the included studies was assessed using a modification of the Cochrane risk of bias 2.0 tool, and the certainty of the evidence using the grading of recommendations assessment, development, and evaluation (GRADE) approach. For each outcome, interventions were classified in groups from the most to the least beneficial or harmful following GRADE guidance.
RESULTS
463 trials enrolling 166 581 patients were included; 267 (57.7%) trials and 89 814 (53.9%) patients are new from the previous iteration; 265 (57.2%) trials evaluating treatments with at least 100 patients or 20 events met the threshold for inclusion in the analyses. Compared with standard care, three drugs reduced mortality in patients with mostly severe disease with at least moderate certainty: systemic corticosteroids (risk difference 23 fewer per 1000 patients, 95% credible interval 40 fewer to 7 fewer, moderate certainty), interleukin-6 receptor antagonists when given with corticosteroids (23 fewer per 1000, 36 fewer to 7 fewer, moderate certainty), and Janus kinase inhibitors (44 fewer per 1000, 64 fewer to 20 fewer, high certainty). Compared with standard care, two drugs probably reduce hospital admission in patients with non-severe disease: nirmatrelvir/ritonavir (36 fewer per 1000, 41 fewer to 26 fewer, moderate certainty) and molnupiravir (19 fewer per 1000, 29 fewer to 5 fewer, moderate certainty). Remdesivir may reduce hospital admission (29 fewer per 1000, 40 fewer to 6 fewer, low certainty). Only molnupiravir had at least moderate quality evidence of a reduction in time to symptom resolution (3.3 days fewer, 4.8 fewer to 1.6 fewer, moderate certainty); several others showed a possible benefit. Several drugs may increase the risk of adverse effects leading to drug discontinuation; hydroxychloroquine probably increases the risk of mechanical ventilation (moderate certainty).
CONCLUSION
Corticosteroids, interleukin-6 receptor antagonists, and Janus kinase inhibitors probably reduce mortality and confer other important benefits in patients with severe covid-19. Molnupiravir and nirmatrelvir/ritonavir probably reduce admission to hospital in patients with non-severe covid-19.

Journal of Drugs in Dermatology : JDD Jul 2023This article describes the clinical trial, safety, and efficacy of ruxolitinib 1.5% cream or repigmentation in patients with vitiligo.
BACKGROUND
This article describes the clinical trial, safety, and efficacy of ruxolitinib 1.5% cream or repigmentation in patients with vitiligo.
DATA SOURCES
A systematic review was done using ruxolitinib or Opzelura in MEDLINE (PubMed) and EMBASE.
CLINICALTRIALS
gov was used to identify ongoing or unpublished studies.
STUDY SELECTION AND DATA EXTRACTION
Studies included were written in English and relevant to pharmacology, clinical trials, safety, and efficacy.
DATA SYNTHESIS
In two 52-week phase 3 trials, 52.0% of subjects had at least 75% improvement in their Facial Vitiligo Area Scoring Index (F-VASI).
RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE
Ruxolitinib is a topical Janus kinase (JAK) inhibitor newly approved by the US Food and Drug Administration for repigmentation in patients with vitiligo.
CONCLUSION
Topical ruxolitinib is the first medication approved for repigmentation in patients with vitiligo. It is a safe and effective treatment; however, cost may be a barrier to some patients when prescribing this medication. Trials to compare the efficacy and side effect profile of topical ruxolitinib with other topical treatments are still needed. Grossmann MC, Haidari W, Feldman SR.

Meta-Analysis
BACKGROUND
On the basis of safety data for patients with inflammatory rheumatism or inflammatory bowel disease, treatment with Janus kinase (JAK) inhibitors (JAKi) has been linked to the occurrence of major adverse cardiovascular events (MACE). However, these inflammatory diseases are proatherogenic; in contrast, patients with atopic dermatitis (AD) do not usually have a high cardiovascular (CV) comorbidity burden.
OBJECTIVES
To perform a systematic review and meta-analysis of MACE in patients with AD treated with JAKi.
METHODS
We systematically searched PubMed, Embase, Cochrane Library and Google Scholar from their inception to 2 September 2022. Cohort studies, randomized controlled trials and pooled safety analyses providing CV safety data on patients taking JAKi for AD were selected. We included patients aged ≥ 12 years. We built a 'controlled-period' cohort (n = 9309; 6000 exposed to JAKi and 3309 exposed to comparators) and an 'all-JAKi' cohort (n = 9118 patients exposed to a JAKi in any of the included studies). The primary outcome was a composite of acute coronary syndrome (ACS), ischaemic stroke and CV death. The broader secondary MACE outcome encompassed ACS, stroke (whether ischaemic or haemorrhagic), transient ischaemic attack and CV death. The frequency of primary and secondary MACE was assessed in both cohorts. A fixed-effects meta-analysis using the Peto method was used to calculate the odds ratio (OR) for MACE in the 'controlled-period' cohort. Evaluation of the risk of bias was done using the Cochrane risk-of-bias tool (version 2). Certainty of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.
RESULTS
Eight per cent of the records identified initially met the selection criteria, corresponding to 23 records included in the 'all-JAKi' cohort. Patients had been exposed to baricitinib, upadacitinib, abrocitinib, ivarmacitinib, placebo or dupilumab. Four primary events (three with JAKi and one with placebo) and five secondary events (four with JAKi and one with placebo) occurred among 9309 patients in the 'controlled-period' cohort (MACE frequency 0.04% and 0.05%, respectively). Eight primary events and 13 secondary events occurred among 9118 patients in the 'all-JAKi' cohort (MACE frequency 0.08% and 0.14%, respectively). The OR for primary MACE in patients with AD treated with JAKi vs. placebo or dupilumab was 1.35 (95% confidence interval 0.15-12.21; I2 = 12%, very low certainty of evidence).
CONCLUSIONS
Our review highlights rare cases of MACE among JAKi users for AD. JAKi may have little-to-no effect on the occurrence of MACE in patients with AD vs. comparators, but the evidence is uncertain. Real-life long-term population-level safety studies are needed.
