Abstract
Rheumatoid arthritis is a world leading cause of musculoskeletal disease. With the introduction of biological agents as treatment alternatives the clinical possibilities have grown exponentially. Currently most common Disease-modifying anti-rheumatic drugs (DMARDs) treatment option involves intravenous or subcutaneous injection, and some patients struggle to respond to DMARDs or lose their primary reaction. An oral drug formulation with lowered costs of manufacturing and flexibility for healthcare workers to preferably perform treatment will result in decreased healthcare expenditures and increased medication compliance. The JAK-STAT inhibitors, a new class of small molecules drugs, fulfills these criteria and has recently shown efficacy in rheumatoid arthritis. Here we give a summary of how JAK-STAT inhibitors function and a detailed review of current clinical trials. Convincing clinical results suggest that therapeutic inhibition of the JAK proteins can effectively modulate a complex cytokine-driven inflammation.

Abstract
Patients with autoimmune rheumatic diseases (ARD) have an increased risk for tuberculosis (TB). The use of tumor necrosis factor inhibitors (TNFi) and glucocorticoids in these patients has been associated with an increased prevalence of latent TB reactivation. Over the last few years, several biologic disease-modifying anti-rheumatic drugs (bDMARDs), other than TNFi (e.g. rituximab, abatacept, tocilizumab, secukinumab) and targeted synthetic DMARDs (tsDMARDs) [e.g. apremilast, Janus kinase (JAK) inhibitors] have been used for the treatment of patients with ARD. For many of these drugs, especially the newer ones like JAK inhibitors or antibodies against interleukin (IL)-23, most data stem from randomized clinical trials and few are available from real life clinical experience. We sought to review the current evidence for TB risk in patients with ARD treated with tsDMARDs or bDMARDs, other than TNFi. It seems that some of these drugs are associated with a lower TB risk, indirectly compared with TNFi treatment. In fact, it appears that rituximab, apremilast and inhibitors of IL-17 and IL-23 might be safer, while more data are needed for JAK inhibitors. As seen in TNFi, risk for TB is more pronounced in TB-endemic areas. Screening for latent TB must precede initiation of any tsDMARDs or bDMARDs. The growing use of non-TNFi agents has raised the need for more real-life studies that would compare the risk for TB between TNFi and other treatment modalities for ARD. Knowledge about the TB-safety profile of these drugs could help in the decision of drug choice in patients with confirmed latent TB infection or in TB endemic areas.

Abstract
INTRODUCTION Janus kinases inhibitors (anti-JAKs), including tofacitinib, baricitinib, upadacitinib, and filgotinib, represent a new class of synthetic targeted drugs for the treatment of rheumatoid arthritis (RA). In this review, the risk of active tuberculosis (TB) occurrence in patients receiving anti-JAKs was assessed. The literature on this topic, updated to 29 February 2020 was reviewed. Overall, 40 reports (22 tofacitinib, 10 baricitinib, 5 upadacitinib, 3 filgotinib) were examined. A low frequency, not exceeding 0.25%, of active TB cases in patients were exposed to anti-JAKs. Only 1 of 89 recorded cases in tofactinib and baricitinib exposure occurred in countries at intermediate or high TB risk, and most of the cases probably were due to first mycobacterium tuberculosis (Mtb) exposure. Although no cases were observed in patients receiving upadacitinib and filgotinib, long-term trials and data from real-life are required to more precisely address the TB risk associated with the two drugs. AREAS COVERED Discussion on the TB risk associated with anti-JAKs, and on the need for accurate evaluation of host-related risk factors in high risk countries. EXPERT OPINION Available data on anti-JAKs suggest a negligible risk of active TB occurrence in low endemic areas.

Abstract
BACKGROUND & AIMS We evaluated the efficacy and safety of upadacitinib, an oral selective Janus kinase 1 inhibitor, in a randomized trial of patients with Crohn's disease (CD). METHODS We performed a double-blind, phase 2 trial in adults with moderate to severe CD and inadequate response or intolerance to immunosuppressants or tumor necrosis factor antagonists. Patients were randomly assigned (1:1:1:1:1:1) to groups given placebo; or 3 mg, 6 mg, 12 mg, or 24 mg upadacitinib twice daily; or 24 mg upadacitinib once daily and were evaluated by ileocolonoscopy at weeks 12 or 16 of the induction period. Patients who completed week 16 were re-randomized to a 36-week period of maintenance therapy with upadacitinib. The primary endpoints were clinical remission at week 16 and endoscopic remission at week 12 or 16 using the multiple comparison procedure and modeling and the Cochran-Mantel-Haenszel test, with a 2-sided level of 10%. RESULTS Among the 220 patients in the study, clinical remission was achieved by 13% of patients receiving 3 mg upadacitinib, 27% of patients receiving 6 mg upadacitinib (P < .1 vs placebo), 11% of patients receiving 12 mg upadacitinib, and 22% of patients receiving 24 mg upadacitinib twice daily, and by 14% of patients receiving 24 mg upadacitinib once daily, vs 11% of patients receiving placebo. Endoscopic remission was achieved by 10% (P < .1 vs placebo), 8%, 8% (P < .1 vs placebo), 22% (P < .01 vs placebo), and 14% (P < .05 vs placebo) of patients receiving upadacitinib, respectively, vs none of the patients receiving placebo. Endoscopic but not clinical remission increased with dose during the induction period. Efficacy was maintained for most endpoints through week 52. During the induction period, patients in the upadacitinib groups had higher incidences of infections and serious infections vs placebo. Patients in the twice-daily 12 mg and 24 mg upadacitinib groups had significant increases in total, high-density lipoprotein, and low-density lipoprotein cholesterol levels compared with patients in the placebo group. CONCLUSIONS In a phase 2 trial of patients with CD, upadacitinib induced endoscopic remission in a significant proportion of patients compared with placebo. Upadacitinib's benefit/risk profile supports further development for treatment of CD. (Clinicaltrials.gov, Number: NCT02365649).

Abstract
OBJECTIVES To inform the 2019 update of the European League against Rheumatism (EULAR) recommendations for the management of rheumatoid arthritis (RA). METHODS A systematic literature research (SLR) to investigate the efficacy of any disease-modifying antirheumatic drug (DMARD) (conventional synthetic (cs)DMARD, biological (b) and biosimilar DMARD, targeted synthetic (ts)DMARD) or glucocorticoid (GC) therapy in patients with RA was done by searching MEDLINE, Embase and the Cochrane Library for articles published between 2016 and 8 March 2019. RESULTS 234 abstracts were selected for detailed assessment, with 136 finally included. They comprised the efficacy of bDMARDs versus placebo or other bDMARDs, efficacy of Janus kinase (JAK) inhibitors (JAKi) across different patient populations and head-to-head of different bDMARDs versus JAKi or other bDMARDs. Switching of bDMARDs to other bDMARDs or tsDMARDs, strategic trials and tapering studies of bDMARDs, csDMARDs and JAKi were assessed. The drugs evaluated included abatacept, adalimumab, ABT-122, baricitinib, certolizumab pegol, SBI-087, CNTO6785, decernotinib, etanercept, filgotinib, golimumab, GCs, GS-9876, guselkumab, hydroxychloroquine, infliximab, leflunomide, mavrilimumab, methotrexate, olokizumab, otilimab, peficitinib, rituximab, sarilumab, salazopyrine, secukinumab, sirukumab, tacrolimus, tocilizumab, tofacitinib, tregalizumab, upadacitinib, ustekinumab and vobarilizumab. The efficacy of many bDMARDs and tsDMARDs was shown. Switching to another tumour necrosis factor inhibitor (TNFi) or non-TNFi bDMARDs after TNFi treatment failure is efficacious. Tapering of DMARDs is possible in patients achieving long-standing stringent clinical remission; in patients with residual disease activity (including patients in LDA) the risk of flares is increased during the tapering. Biosimilars are non-inferior to their reference products. CONCLUSION This SLR informed the task force regarding the evidence base of various therapeutic regimen for the development of the update of EULAR's RA management recommendation.

Abstract
BACKGROUND & AIMS We evaluated the efficacy and safety of upadacitinib, an oral selective inhibitor of Janus kinase 1, as induction therapy for ulcerative colitis (UC). METHODS We performed a multicenter, double-blind, phase 2b study of 250 adults with moderately to severely active UC and an inadequate response, loss of response, or intolerance to corticosteroids, immunosuppressive agents, and/or biologic therapies. Patients were randomly assigned to groups that received placebo or induction therapy with upadacitinib (7.5 mg, 15 mg, 30 mg, or 45 mg, extended release), once daily for 8 weeks. The primary endpoint was the proportion of participants who achieve clinical remission according to the adapted Mayo score at week 8. No multiplicity adjustments were applied. RESULTS At week 8, 8.5%, 14.3%, 13.5%, and 19.6% of patients receiving 7.5 mg, 15 mg, 30 mg, or 45 mg upadacitinib, respectively, achieved clinical remission compared with none of the patients receiving placebo (P = .052, P = .013, P = .011, and P = .002 compared with placebo, respectively). Endoscopic improvement at week 8, defined as endoscopic subscore of ≤ 1, was achieved in 14.9%, 30.6%, 26.9%, and 35.7% of patients receiving upadacitinib 7.5 mg, 15 mg, 30 mg, or 45 mg, respectively, compared with 2.2% receiving placebo (P = .033, P < .001, P < .001, and P < .001 compared with placebo, respectively). One event of herpes zoster and 1 participant with pulmonary embolism and deep venous thrombosis (diagnosed 26 days after treatment discontinuation) were reported in the group that received upadacitinib 45 mg once daily. Increases in serum lipid levels and creatine phosphokinase with upadacitinib were observed. CONCLUSION In a phase 2b trial, 8 weeks of treatment with upadacitinib was more effective than placebo for inducing remission in patients with moderately to severely active UC.

Abstract
Uveitis is a spectrum of inflammatory disorders characterized by ocular inflammation and is one of the leading causes of preventable visual loss. The main aim of the treatment of uveitis is to control the inflammation, prevent recurrences of the disease and preserve vision while minimizing the adverse effects associated with the therapeutic agents. Initial management of uveitis relies heavily on the use of corticosteroids. However, monotherapy with high-dose corticosteroids is associated with side effects and cannot be maintained long term. Therefore, steroid-sparing agents are needed to decrease the burden of steroid therapy. Currently, the therapeutic approach for non-infectious uveitis (NIU) consists of a step-ladder strategy with the first-line option being corticosteroids in various formulations followed by the use of first-, second- and third-line agents in cases with suboptimal steroid response. Unfortunately, the agents currently at our disposal have limitations such as having a narrow therapeutic window along with their own individual potential side-effect profiles. Therefore, research has been targeted to identify newer drugs as well as new uses for older drugs that target specific pathways in the inflammatory response. Such efforts are made in order to provide targeted and safer therapy with reduced side effects and greater efficacy. Several specially designed molecular antibodies are currently in various phases of investigations that can potentially halt the inflammation in patients with NIU. In the review, we have provided a comprehensive overview of the current and upcoming therapeutic options for patients with NIU.

Abstract
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.

Abstract
The incidence and prevalence of ulcerative colitis are increasing globally. Although the exact cause and pathogenesis of this disease is unclear, research has led to a better understanding of the condition and to identification of new targets for therapy, which in turn has encouraged the development of new therapies. As well as biologic therapies, which have changed the way inflammatory bowel disease is managed, small molecules have been developed for the treatment of ulcerative colitis. These small molecule treatments are orally administered and are likely to bring a substantial shift in the way this chronic disease is treated. Oral therapies offer many advantages over infusion therapies, such as ease of use, increased acceptability by patients, and reduction of cost. This Review focuses not only on oral therapies that have been approved for use in ulcerative colitis, but also on those that are in development, providing a comprehensive overview for clinicians of available oral therapies and drugs that are likely to become available. We have also reviewed drugs that have shown promise in preclinical studies and could be effective future therapies.

Abstract
INTRODUCTION The Janus kinase (JAK) inhibitor therapeutic class has shown significant clinical benefit in the treatment of rheumatoid arthritis (RA). We sought to gain insight into the mode of action and immunological effects of filgotinib, a JAK1 selective inhibitor, in active RA by analyzing secreted and cell-based biomarkers key to RA pathophysiology in two phase 2b trials of filgotinib in active RA. METHODS Immune cell subsets and 34 serum biomarkers were analyzed longitudinally over 12 weeks using blood samples collected from patients with active RA receiving filgotinib (100 or 200 mg once daily) or placebo (PBO) in the two phase 2b trials (DARWIN 1, on a background of methotrexate, and DARWIN 2, as monotherapy). RESULTS Consistently across both studies, filgotinib treatment decreased multiple immune response biomarkers that have key roles in RA for immune response, and decreased markers that promote matrix degradation, angiogenesis, leukocyte adhesion, and recruitment. Filgotinib did not significantly modulate T and natural killer (NK) lymphoid subsets, but slightly increased B cell numbers after 12 weeks. Multiple correlations were observed for changes in biomarkers with disease activity score 28-CRP. MIP1β showed modest predictivity at baseline for ACR50 response at 12 weeks in the 100 mg filgotinib dose across both studies (AUROC, 0.65 and 0.67, p < 0.05). CONCLUSIONS Filgotinib regulates biomarkers from multiple pathways, indicative of direct and indirect network effects on the immune system and the stromal response. These effects were not associated with reductions of major circulating lymphoid populations. TRIAL REGISTRATION ClinicalTrials.gov, NCT01888874, NCT01894516.

Abstract
Cytokines are key drivers of inflammation in RA, and anti-cytokine therapy has improved the outcome of RA. Janus Kinases (JAK) are intracellular tyrosine kinases linked to intracellular domains of many cytokine receptors. There are four JAK isoforms: JAK1, JAK2, JAK3 and TYK2. Different cytokine receptor families utilize specific JAK isoforms for signal transduction. Phosphorylation of JAK when cytokine binds to its cognate receptor leads to phosphorylation of other intracellular molecules that eventually leads to gene transcription. Oral JAK inhibitors (JAKi) have been developed as anti-cytokine therapy in RA. Two JAKi, tofacitinib and baricitinib, have been approved recently for the treatment of RA, and many JAKi are currently in development. JAKi inhibit JAK isoforms with different selectivity. This review discusses the efficacy and safety of JAKi in RA, in particular the potential clinical significance of JAKi selectivity.

Abstract
Janus kinase (JAK)/signal transducers and activators of transcription (STATs) are a group of molecules associated with one of the major pathways through which many cytokines exert and integrate their function, and as such they are increasingly recognized as playing critical role in the pathogenesis subserving various immune-mediated diseases, including RA, PsA, SpAs, IBD, skin disorders (e.g. alopecia areata, atopic dermatitis), single-gene disorders like interferonopathies, and others. JAKs are the key initiating players of the JAK/STAT pathway. Upon binding of their respective effector molecules (cytokines, IFNs, growth factors and others) to type I and type II receptors, JAKs are activated, and through phosphorylation of themselves and of other molecules (including STATs), they mediate signal transduction to the nucleus. A class of drugs—called JAK inhibitors or JAKinibs—that block one or more JAKs has been developed in the last decade, and now numbers >20 members. Although, so far, JAK inhibitors have been marketed only for RA and PsA, these drugs have been tested in phase 2 and phase 3 clinical trials for other inflammatory conditions and beyond. In this review, we summarize the clinical data, including efficacy and safety, available for JAK inhibitors used in some immune-mediated conditions other than RA.

Abstract
Background To evaluate the effect of upadacitinib on patient-reported outcomes (PROs) in patients with RA who had an inadequate response to csDMARDs. Methods Patients in SELECT-NEXT, a randomised controlled trial, were on a background of csDMARDs and received upadacitinib 15 mg and 30 mg or placebo daily for 12 weeks. PROs included Patient Global Assessment of Disease Activity (PtGA), pain, Health Assessment Questionnaire-Disability Index (HAQ-DI), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), duration and severity of morning (AM) joint stiffness, Short Form 36 Health Survey (SF-36), and Work Instability Scale for RA (RA-WIS). Least squares mean (LSM) changes were based on mixed-effect repeated measure models. Percentages of patients reporting improvements ≥ minimum clinically important differences (MCIDs) and scores ≥ normative values and number needed to treat (NNT) were determined; group comparisons used chi-square tests. Results Data from 661 patients were analysed. Compared with placebo, patients receiving upadacitinib reported statistically significant improvements (both doses, P < 0.05) in PtGA, pain, HAQ-DI, FACIT-F, duration and severity of AM stiffness, SF-36 (PCS and 6/8 domains), and RA-WIS at week 12. Significantly, more upadacitinib-treated patients (both doses, P < 0.05) reported improvements ≥ MCID in PtGA, pain, HAQ-DI, FACIT-F, AM stiffness, SF-36 (PCS and 4 or 7/8 domains), and RA-WIS and scores ≥ normative values in HAQ-DI, FACIT-F, and SF-36 (PCS and 4 or 5/8 domains). For most PROs, the incremental NNT with upadacitinib to report clinically meaningful improvement from baseline ranged from 4 to 8 patients. Conclusions Upadacitinib 15 mg or 30 mg daily for 12 weeks resulted in significant and clinically meaningful improvements in global disease activity, pain, physical function, fatigue, duration and severity of AM stiffness, HRQOL, and work instability among csDMARD-IR patients with RA.

Abstract
Introduction: Rheumatoid arthritis (RA) is a chronic, refractory disorder caused by autoimmunity in the synovial joints. Disease-modifying anti-rheumatic drugs (DMARDs) and biologicals offer remission in only two-thirds of RA patients within 3 months, hence new therapeutic approaches are necessary. Tyrosine kinase inhibitors (TKIs) are newly developed small molecule drugs which have demonstrated encouraging results in this disease.Areas covered: The key findings from phase I and II clinical trials that have investigated the use of novel TKIs in the treatment of RA are discussed. We examined the literature published between January 2014 to January 2019 using electronic databases including PubMed, Web of Science, Medline, Embase, and Google Scholar. Additional information about phase I and II trials on the ClinicalTrial.gov website up to January 2019 was also retrieved.Expert opinion: JAK inhibitors are promising drugs with sound efficacy and acceptable safety and may be beneficial to patients who do not respond to DMARDs and biologicals. The response rates among RA patients to TKIs are diverse; genetic and environmental factors may be involved in the varying responses which are closely related to the pathogenesis of RA. Future studies may reveal the underlying mechanisms of resistance and non-response.

Abstract
BACKGROUND The ACR20 has been validated as the best discriminator of efficacy in placebo-controlled trials, but not in head-to-head trials comparing effective therapies in patients with rheumatoid arthritis (RA). We assessed the most discriminatory ACR response and most discriminatory percent improvement in disease activity measures for Simplified Disease Activity index (SDAI), Clinical Disease Activity index (CDAI), and 28-joint Disease Activity Score based on C-reactive protein (DAS28(CRP)) using different patient populations and trial designs. METHODS Data from two placebo-controlled studies in established RA and two head-to-head studies in early RA were analyzed. The numeric ACR response for each treatment and P value for the difference between treatments were calculated at multiple time points to determine the ACR response associated with the lowest P value. Similarly, values for percent improvement from baseline in SDAI, CDAI, and DAS28(CRP) with the most discrimination between treatments were examined. RESULTS In the head-to-head early RA trials, the minimum P value and greatest treatment difference between the active comparator arms at 6 months was achieved at higher ACR rates and greater percent improvements in other disease activity measures. In established RA, lower responses (minimum P value and maximum treatment difference) and smaller improvements in disease activity scores had better discriminatory ability at 6 months. CONCLUSIONS The most discriminatory ACR response rate and percent improvement in disease activity measures were higher in head-to-head active comparator trials in early RA versus placebo-controlled trials in established RA. This difference should be considered in future clinical trial designs. TRIAL REGISTRATION NCT00195663, NCT00420927, NCT00195702.

Abstract
In the past ten years, the better understanding of the pathophysiological mechanisms underlying inflammatory and autoimmune diseases has led to the emergence of many targeted therapies. Among them, the Janus kinase inhibitors are acting upstream in the inflammatory cascade of several key cytokines in disorders such as rheumatoid arthritis, ulcerative colitis or psoriasis. At the moment, these three diseases represent the only indications validated by the FDA and the EMA of the use of JAK inhibitors apart from hematology. Preclinical data and therapeutic trials indicate their efficacy in other autoimmune or inflammatory conditions, such as lupus, dermatomyositis, ankylosing spondylitis, sarcoidosis and giant cell arteritis. This review provides a summary of current use and advancement of knowledge in the use of JAK inhibitors in pathologies faced by internists.

Abstract
Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease characterized by joint involvement, extra-articular manifestations, comorbidities, and increased mortality. In the last few decades, the management of RA has been dramatically improved by the introduction of a treat-to-target approach aiming to prevent joint damage progression. Moreover, the increasing knowledge about disease pathogenesis allowed the development of a new drug class of biologic agents targeted on immune cells and proinflammatory cytokines involved in RA network. Despite the introduction of several targeted drugs, a significant proportion of RA patients still fail to achieve the clinical target; so, more recently the focus of research has been shifted toward the inhibition of kinases involved in the transduction of the inflammatory signal into immune cells. In particular, two Janus kinase (JAK) inhibitors, baricitinib and tofacitinib, have been licensed for the treatment of RA as a consequence of a very favorable profile observed in randomized controlled trials (RCTs) conducted across different RA subpopulations. Both these new compounds are active on the majority of four JAK family members (JAK1, JAK2, JAK3, and TYK2), whereas the most recent emerging approach is directed toward the development of JAK1 selective inhibitors (upadacitinib and filgotinib) with the aim to improve the safety profile by minimizing the effects on JAK3 and, especially, JAK2. In this narrative review, we discuss the rationale for JAK inhibition in RA, with a special focus on the role of JAK1 selective blockade and a detailed description of available data from the results of clinical trials on upadacitinib and filgotinib.

Abstract
Significant successes in the use of biological agents (BA) have been achieved in the treatment of rheumatoid arthritis (RA); nonetheless, about 36% of patients cannot respond to therapy or achieve the expected effect. A new area in the treatment of RA is the use of Janus kinase (JAK) inhibitors, targeted synthetic disease-modifying anti-rheumatic drugs (chemical molecules with a molecular weight <1 kDa for oral administration) that inhibit the activity of intracellular signaling systems. The authors consider the clinical achievements and prospects, which open the use of JAK inhibitors in the treatment of RA.

Abstract
The two major forms of inflammatory bowel disease (IBD), encompassing Crohn's disease (CD) and ulcerative colitis (UC), are chronic immune-mediated conditions characterised by an increased production of pro-inflammatory cytokines that act as critical drivers of intestinal inflammation. Anti-cytokine therapy has been shown to improve clinical outcomes in IBD. Janus kinases (JAKs) are tyrosine kinases that bind different intracellular cytokine receptors, leading to phosphorylation of signal transducer and activation of transcription molecules implicated on targeted gene transcription. Four isoforms of JAKs have been described: JAK1, JAK2, JAK3 and TYK2. Oral JAK inhibitors (JAKi) have been developed as synergic anti-cytokine therapy in IBD, showing different selectivity towards JAK isoforms. Tofacitinib, a pan-JAK inhibitor, has been recently approved for the treatment of moderate-to-severe UC. With the aim of improving the benefit: risk ratio of this drug class, several second-generation subtype-selective JAKi are under development. However, whether selective inhibition of JAK isoforms is associated with an increased clinical efficacy and/or a better safety profile remains debatable. The aim of this review is to critically review the preclinical and clinical data for the differential selectivity of JAK inhibitors and to summarise the potential clinical implications of the selective JAK inhibitors under development for UC and CD.

Abstract
Cytokines play a central role in the pathophysiology of autoimmune and inflammatory diseases. Several cytokines signal through the JAK-STAT pathway, which is now recognized as a major target to inhibit the effect of a wide array of cytokines. JAK inhibitors are increasingly used in the setting of inflammatory and autoimmune diseases. While the currently approved drugs are panJAK inhibitors, more selective small molecules are being developed and tested in various rheumatic disorders. In this extensive review, we present evidence- or hypothesis-based perspectives for these drugs in various rheumatologic conditions, such as rheumatoid arthritis, systemic lupus erythematosus, giant cell arteritis, and autoinflammatory diseases.

Abstract
The past decade has witnessed an explosion in trial data on JAK inhibitors (JAKi). These small molecules target the Janus kinase - signal transducer and activator of transcription (JAK-STAT) pathway, blocking crucial cytokines across a septum of rheumatic diseases. As a class, JAKi are beginning to demonstrate efficacy on par, if not superior to biologics. Two first generation JAKi are licensed for use in inflammatory arthritis; tofacitinib and baricitinib. Next-generation JAKi have been designed with selective affinity for one JAK enzymes, the aim to reduce unwanted adverse effects without declining clinical efficacy. Emerging data with selective JAK1 inhibitors upadacitinib and filgotinib looks very promising. Despite differences in selectivity between JAKi, an overlap exists in their safety profiles. Across the class, a characteristic safety signal is emerging with viral opportunistic infections, particularly herpes zoster. Post marketing drug surveillance will be essential in evaluating the long-term risk with these agents.

Abstract
:
Rheumatoid Arthritis (RA) is a chronic inflammatory disease characterized by synovial
inflammation and hyperplasia, autoantibody production, cartilage and bone destruction and several
systemic features. Cardiovascular, pulmonary, psychological, and muscle involvement are the
main comorbidities of RA and are responsible for the severity of the disease and long-term prognosis.
:
Pharmacological treatment of rheumatic diseases has evolved remarkably over the past years. In
addition, the widespread adoption of treat to target and tight control strategies has led to a substantial
improvement of outcomes, so that drug-free remission is nowadays a realistic goal in the
treatment of RA. However, despite the availability of multiple therapeutic options, up to 40% of
patients do not respond to current treatments, including biologics. Small-molecule therapies offer
an alternative to biological therapies for the treatment of inflammatory diseases. In the past 5
years, a number of small-molecule compounds targeting Janus Kinases (JAKs) have been developed.
Since JAKs are essential for cell signaling in immune cells, in particular controlling the response
to many cytokines, their inhibitors quickly became a promising class of oral therapeutics
that proved effective in the treatment of RA.
:
ofacitinib is the first Janus Kinase (JAK) inhibitor approved for the treatment of RA, followed
more recently by baricitinib. Several other JAK inhibitors, are currently being tested in phase II
and III trials for the treatment of a different autoimmune diseases. Most of these compounds exhibit
an overall acceptable safety profile similar to that of biologic agents, with infections being the
most frequent adverse event. Apart from tofacitinib, safety data on other JAK inhibitors are still
limited. Long-term follow-up and further research are needed to evaluate the general safety profile
and the global risk of malignancy of these small molecules, although no clear association with malignancy
has been reported to date.
:
Here, we will review the main characteristics of JAK inhibitors, including details on their
molecular targets and on the clinical evidences obtained so far in the treatment of RA.

Abstract
IMPORTANCE Patients with active rheumatoid arthritis (RA) despite treatment with biologic disease-modifying antirheumatic drug (bDMARD) therapy need treatment options. OBJECTIVE To evaluate the effects of filgotinib vs placebo on the signs and symptoms of RA in a treatment-refractory population. DESIGN, SETTING, AND PARTICIPANTS A 24-week, randomized, placebo-controlled, multinational phase 3 trial conducted from July 2016 to June 2018 at 114 sites internationally, randomizing 449 adult patients (and treating 448) with moderately to severely active RA and inadequate response/intolerance to 1 or more prior bDMARDs. INTERVENTIONS Filgotinib, 200 mg (n = 148); filgotinib, 100 mg (n = 153); or placebo (n = 148) once daily; patients continued concomitant stable conventional synthetic DMARDs (csDMARDs). MAIN OUTCOMES AND MEASURES The primary end point was the proportion of patients who achieved 20% improvement in the American College of Rheumatology criteria (ACR20) at week 12. Secondary outcomes included week 12 assessments of low disease activity (disease activity score in 28 joints-C-reactive protein [DAS28-CRP] ≤3.2) and change in Health Assessment Questionnaire-Disability Index, 36-Item Short-Form Health Survey Physical Component, and Functional Assessment of Chronic Illness Therapy-Fatigue scores, as well as week 24 assessment of remission (DAS28-CRP <2.6) and adverse events. RESULTS Among 448 patients who were treated (mean [SD] age, 56 [12] years; 360 women [80.4%]; mean [SD] DAS28-CRP score, 5.9 [0.96]; 105 [23.4%] with ≥3 prior bDMARDs), 381 (85%) completed the study. At week 12, more patients receiving filgotinib, 200 mg (66.0%) or 100 mg (57.5%), achieved ACR20 response (placebo, 31.1%; difference vs placebo: 34.9% [95% CI, 23.5%-46.3%] and 26.4% [95% CI, 15.0%-37.9%], respectively; both P < .001), including among patients with prior exposure to 3 or more bDMARDs (70.3%, 58.8%, and 17.6%, respectively; difference vs placebo: 52.6% [95% CI, 30.3%-75.0%] for filgotinib, 200 mg, and 41.2% [95% CI, 17.3%-65.0%] for filgotinib, 100 mg; both P < .001). The most common adverse events were nasopharyngitis (10.2%) for filgotinib, 200 mg; headache, nasopharyngitis, and upper respiratory infection (5.9% each) for filgotinib, 100 mg; and RA (6.1%) for placebo. Four uncomplicated herpes zoster cases and 1 retinal vein occlusion were reported with filgotinib; there were no opportunistic infections, active tuberculosis, malignancies, gastrointestinal perforations, or deaths. CONCLUSIONS AND RELEVANCE Among patients with active RA who had an inadequate response or intolerance to 1 or more bDMARDs, filgotinib, 100 mg daily or 200 mg daily, compared with placebo resulted in a significantly greater proportion achieving a clinical response at week 12. However, further research is needed to assess longer-term efficacy and safety. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02873936.

J Leukoc Biol 2019; 106:1063-1068.

Abstract
Methotrexate (MTX) is recognized as the anchor drug in the algorithm treating chronic arthritis (RA, psoriatic arthritis), as well as a steroid sparing agent in other inflammatory conditions (polymyalgia rheumatica, vasculitis, scleroderma). Its main mechanism of action has been related to the increase in extracellular adenosine, which leads to the effects of A2A receptor in M1 macrophages that dampens TNFα and IL12 production and increases IL1Ra and TNFRp75. By acting on A2B receptor on M2 macrophages it enhances IL10 synthesis and inhibits NF-kB signaling. MTX has also been shown to exert JAK inhibition of JAK2 and JAK1 when tested in Drosophila melanogaster as a model of kinase activity and in human cell lines (nodular sclerosis Hodgkin's lymphoma and acute myeloid leukemia cell lines). These effects may explain why MTX leads to clinical effects similar to anti-TNFα biologics in monotherapy, but is less effective when compared to anti-IL6R in monotherapy, which acting upstream exerts major effects downstream on the JAK1-STAT3 pathway. The MTX effects on JAK1/JAK2 inhibition also allows to understand why the combination of MTX with Leflunomide, or JAK1/JAK3 inhibitor leads to better clinical outcomes than monotherapy, while the combination with JAK1/JAK2 or JAK1 specific inhibitors does not seem to exert additive clinical benefit.

Abstract
AbstractThe use of cytotoxic chemotherapy in the treatment of malignant and inflammatory disorders is beset by considerable adverse effects related to nonspecific cytotoxicity. Accordingly, a mechanistic approach to therapeutics has evolved in recent times with small molecular inhibitors of intracellular signaling pathways involved in disease pathogenesis being developed for clinical use, some with unparalleled efficacy and tolerability. Nevertheless, there are emerging concerns regarding an association with certain small molecular inhibitors and opportunistic infections, including invasive fungal diseases. This is perhaps unsurprising, given that the molecular targets of such agents play fundamental and multifaceted roles in orchestrating innate and adaptive immune responses. Nevertheless, some small molecular inhibitors appear to possess intrinsic antifungal activity and may therefore represent novel therapeutic options in future. This is particularly important given that antifungal resistance is a significant, emerging concern. This paper is a comprehensive review of the state-of-the-art in the molecular immunology to fungal pathogens as applied to existing and emerging small molecular inhibitors.

Hybrid micelles containing methotrexate-conjugated polymer and co-loaded with microRNA-124 for rheumatoid arthritis therapy. Theranostics 2019; 9:5282-5297.

Abstract
Purpose: Methotrexate (MTX) is a first-line drug for rheumatoid arthritis (RA)therapy. However, MTX monotherapy often results in irreversible joint damage due to its slow onset of action and long duration. microRNA-124 (miR-124) has shown direct bone protection activity against RA. A co-delivery system for MTX and microRNA combination may provide therapeutic synergy. Methods: Methotrexate-conjugated polymer hybrid micelles (M-PHMs) were prepared by self-assembly of two functional amphiphilic polymers (MTX-PEI-LA and mPEG-LA) at an optimized weight ratio. Incorporation of microRNA was achieved through electrostatic interactions between microRNA and cationic polymer MTX-PEI-LA. Cellular uptake, endosome escape, biodistribution, and therapeutic efficacy of M-PHMs/miR-124 complexes were investigated and evaluated in RAW264.7 cells and a rat adjuvant-induced arthritis (AIA) model. Results: M-PHMs/miR-124 complexes exhibited folate receptor-mediated uptake in activated RAW264.7 cells. miR-124 was able to escape from the endosome and down-regulate nuclear factor of activated T cells cytoplasmic1 (NFATc1). M-PHMs/miR-124 complexes accumulated in inflamed joints of AIA rats and showed superior therapeutic efficacy through both anti-inflammatory effect and direct bone protective effect. Combination of miR-124 and MTX in these micelles induced disease remission. Conclusions: M-PHMs/miR-124 was highly effective against RA through therapeutic synergy. Additional studies are warranted to further investigate its therapeutic potential and delineate its mechanisms of action.

Abstract
PURPOSE OF REVIEW Therapies for rheumatoid arthritis (RA) continue to expand rapidly. The purpose of this review is to discuss novel treatment options, including biosimilars, that are available, as well as to highlight promising agents in development. The purpose is also to discuss new emerging safety signals associated with these drugs and to discuss strategies in tapering therapy. RECENT FINDINGS There are several novel RA therapies. These include the interleukin-6 (IL-6) receptor blocker sarilumab, which was approved in 2017. In aggregate, the sarilumab studies show that it is effective in RA, including patients with incomplete responses to methotrexate and anti-tumor necrosis factor inhibitor, and showing superior efficacy when used in higher dose (200 mg every 2 weeks) to standard-dose adalilumab. Other drugs that are currently being studied include the IL-6 cytokine blocker sarikumab, the small targeted molecule filgotinib, and many new biosimilars. Baracitinib failed to achieve approval by the Food and Drug Administration primarily over perceived safety concerns. The two biosimilar drugs currently approved are CT-P13 and SB2, which are based on the reference product infliximab. Although this review summarizes trials examining biologic tapering, additional data are needed to guide clinicians in regards to treatment de-escalation in RA. SUMMARY With the greatly expanded armamentarium of RA treatment options available, it is important for clinicians to understand the data regarding drug efficacy and safety. With remission increasingly attainable, effective drug tapering strategies are needed. Although tapering trials do exist, more studies will be needed to help guide clinical practice.

Abstract
Several Janus kinase (JAK) inhibitors, oral targeted disease-modifying drugs, will be approved for the treatment of rheumatoid arthritis (RA) and other diseases. This review compares and contrasts the efficacy of JAK inhibitors (tofacitinib, baricitinib, upadacitinib, filgotinib, peficitinib and decernotinib) in RA including: early RA methotrexate-naive patients, post methotrexate failure and post biologics. Trials in monotherapy, combination with disease modifying drugs such as methotrexate, and comparing with adalimumab in biologic-naive patients were studied. The efficacy is superior to methotrexate in naive patients and equal or superior to adalimumab depending on the drug and dose. There is a class effect of adverse events. Serious infections occur at a rate similar to other advanced therapies in RA, although more reactivation of herpes zoster occurs.

Abstract
Cytokines, many of which signal through the JAK-STAT (Janus kinase-Signal Transducers and Activators of Transcription) pathway, play a central role in the pathogenesis of inflammatory and autoimmune diseases. Currently three JAK inhibitors have been approved for clinical use in USA and/or Europe: tofacitinib for rheumatoid arthritis, psoriatic arthritis and ulcerative colitis, baricitinib for rheumatoid arthritis, and ruxolitinib for myeloproliferative neoplasms. The clinical JAK inhibitors target multiple JAKs at high potency and current research has focused on more selective JAK inhibitors, almost a dozen of which currently are being evaluated in clinical trials. In this narrative review, we summarize the status of the pan-JAK and selective JAK inhibitors approved or in clinical trials, and discuss the rationale for selective targeting of JAKs in inflammatory and autoimmune diseases.

Abstract
Janus kinase inhibition is promising in the treatment of RA, with already two oral drugs marketed. New compounds are under investigation that are more selective for Janus kinase 1 or Janus kinase 3. Phase II results for filgotinib, upadacitinib, peficitinib and decernotinib are reviewed showing almost consistently a fast dose-dependent clinical improvement similar to already approved drugs tofacitinib and baricitinib. I will reflect on the most frequently reported dose-dependent adverse events and laboratory changes. Some are similar for all drugs of this class, some are more specific for a certain drug, but all may influence future treatment effectiveness in daily practice. This implies the need for a critical evaluation of phase III trials, and eventually trials specifically powered for conclusions on the safety profile and registries once these drugs become marketed. These innovative drugs also need head-to-head trials versus biologics or in-class as well as specific strategy studies to determine their optimal future use.

Abstract
BACKGROUND The Janus kinase 1 (JAK1) pathway has been implicated in the pathogenesis of psoriatic arthritis. We aimed to investigate the efficacy and safety of filgotinib, a selective JAK1 inhibitor, for the treatment of psoriatic arthritis. METHODS The EQUATOR trial was a randomised, double-blind, placebo-controlled phase 2 trial that enrolled adults from 25 sites in seven countries (Belgium, Bulgaria, Czech Republic, Estonia, Poland, Spain, and Ukraine). Patients (aged ≥18 years) had active moderate-to-severe psoriatic arthritis (defined as at least five swollen joints and at least five tender joints) fulfilling Classification for psoriatic arthritis (CASPAR) criteria, active or a documented history of plaque psoriasis, and an insufficient response or intolerance to at least one conventional synthetic disease-modifying anti-rheumatic drug (csDMARD). Patients continued to take csDMARDs during the study if they had received this treatment for at least 12 weeks before screening and were on a stable dose for at least 4 weeks before baseline. Using an interactive web-based system, we randomly allocated patients (1:1) to filgotinib 200 mg or placebo orally once daily for 16 weeks (stratified by current use of csDMARDs and previous use of anti-tumour necrosis factor). Patients, study team, and sponsor were masked to treatment assignment. The primary endpoint was proportion of patients achieving 20% improvement in American College of Rheumatology response criteria (ACR20) at week 16 in the full analysis set (patients who received at least one dose of study drug), which was compared between groups with the Cochran-Mantel-Haenszel test and non-responder imputation method. This trial is registered with ClincalTrials.gov, number NCT03101670. FINDINGS Between March 9, and Sept 27, 2017, 191 patients were screened and 131 were randomly allocated to treatment (65 to filgotinib and 66 to placebo). 60 (92%) patients in the filgotinib group and 64 (97%) patients in the placebo group completed the study; five patients (8%) in the filgotinib group and two patients (3%) in the placebo group discontinued treatment. 52 (80%) of 65 patients in the filgotinib group and 22 (33%) of 66 in the placebo group achieved ACR20 at week 16 (treatment difference 47% [95% CI 30·2-59·6], p<0·0001). 37 (57%) patients who received filgotinib and 39 (59%) patients who received placebo had at least one treatment-emergent adverse event. Six participants had an event that was grade 3 or worse. The most common events were nasopharyngitis and headache, occurring at similar proportions in each group. One serious treatment-emergent adverse event was reported in each group (pneumonia and hip fracture after a fall), one of which (pneumonia) was fatal in the filgotinib group. INTERPRETATION Filgotinib is efficacious for the treatment of active psoriatic arthritis, and no new safety signals were identified. FUNDING Galapagos and Gilead Sciences.

Abstract
BACKGROUND At present, biological disease-modifying anti-rheumatic drugs (DMARDs) are the only treatment recommended for patients with ankylosing spondylitis who have not responded to first-line treatment with non-steroidal anti-inflammatory drugs (NSAIDs). The TORTUGA trial investigated the efficacy and safety of filgotinib, an oral selective Janus kinase 1 (JAK1) inhibitor, for the treatment of patients with active ankylosing spondylitis. METHODS In this completed, randomised, double-blind, placebo-controlled, phase 2 trial, we enrolled adult patients from 30 sites in seven countries (Belgium, Bulgaria, Czech Republic, Estonia, Poland, Spain, and Ukraine). Eligible patients had active ankylosing spondylitis and an inadequate response or intolerance to two or more NSAIDs. Patients were randomly assigned (1:1) with an interactive web-based response system to receive filgotinib 200 mg or placebo orally once daily for 12 weeks. Randomisation was stratified by current use of conventional synthetic DMARDs and previous receipt of anti-tumour necrosis factor therapy. The patients, study team, and study sponsor were masked to treatment assignment. The primary endpoint was the change from baseline in ankylosing spondylitis disease activity score (ASDAS) at week 12, which was assessed in the full analysis set (ie, all randomised patients who received at least one dose of study drug). Safety was assessed according to actual treatment received. This trial is registered with ClinicalTrials.gov, number NCT03117270. FINDINGS Between March 7, 2017, and July 2, 2018, 263 patients were screened and 116 randomly assigned to filgotinib (n=58) or placebo (n=58). 55 (95%) patients in the filgotinib group and 52 (90%) in the placebo group completed the study; three (5%) patients in the filgotinib group and six (10%) in the placebo group discontinued treatment. The mean ASDAS change from baseline to week 12 was -1·47 (SD 1·04) in the filgotinib group and -0·57 (0·82) in the placebo group, with a least squares mean difference between groups of -0·85 (95% CI -1·17 to -0·53; p<0·0001). Treatment-emergent adverse events were reported in 18 patients in each group, the most common being nasopharyngitis (in two patients in the filgotinib group and in four patients in the placebo group). Treatment-emergent adverse events led to permanent treatment discontinuation in two patients (a case of grade 3 pneumonia in the filgotinib group and of high creatine kinase in the placebo group). No deaths were reported during the study. INTERPRETATION Filgotinib is efficacious and safe for the treatment of patients with active ankylosing spondylitis who have not responded to first-line pharmacological therapy with NSAIDs. Further investigation of filgotinib for ankylosing spondylitis is warranted. FUNDING Galapagos and Gilead Sciences.

Abstract
Immune challenge of invading macrophages at sites of infection is associated with release of TNF, which triggers a local cytokine storm as part of the normal inflammatory response. Whereas this response maybe beneficial in fighting off infections, similar responses triggered in autoimmune diseases contribute significantly to the underlying damaging pathology associated with these diseases. Here we show that Takinib, a highly discriminatory inhibitor of transforming growth factor Beta- activated kinase 1 (TAK1), selectively and potently reduces TNF production in pro-inflammatory THP-1 macrophages. A complete survey of 110 cytokines, showed robust loss of proinflammatory cytokine responsiveness to lipopolysaccharide (LPS) and interferon gamma (IFNγ) challenge in response to Takinib. The mechanisms of action of Takinib was recapitulated in TAK1 KO macrophages. TAK1 KO cells showed significant loss of TNF production as well as release of IL-6 in response to LPS challenge. Furthermore, Takinib blocked the ability of exogenously added LPS to promote phosphorylation of, c-Jun, p38 protein kinases as well as downstream transcription factors regulated by nuclear factor κ-light-chain-enhancer of activated B cells (NFκB). In a mouse LPS challenge model, Takinib significantly reduced TNF serum levels. Our findings demonstrate that Takinib has utility in the treatment inflammatory disease by locally suppressing TNF production from invading macrophages.

Abstract
Inflammatory bowel disease (IBD) is a chronic heterogeneous group of diseases that has undergone major advances in the understanding of its etiology and pathogenesis in recent years. The development of biologics had resulted in better overall management of the disease, including lower rates of surgery and better long-term clinical and patient-reported outcomes. Treatment modalities have either been newly developed or extrapolated from their approved use for a different indication. Modes of action and treatment targets have varied as well. Treatments such as vedolizumab and ustekinumab, as well as second-generation corticosteroids have been approved by the US Food and Drug Administration (FDA) for the treatment of IBD. Other agents are currently being developed at various stages of clinical trials including anti-adhesion agents such as etrolizumab and abrilumab, JAK inhibitors such as tofacitinib, and anti-trafficking molecules. Toll-like receptors and phosphatidylcholine are also new promising emerging targets that are being investigated in phase 3 clinical trials. It is projected that many therapies will become available in the coming years if supported by the results of current clinical trials. This will provide IBD patients with a wide array of options and allow physicians to choose the best therapies for each individual patient.

Abstract
OBJECTIVE Baricitinib is an orally administered inhibitor of JAK1 and JAK2 that has been shown to be effective in treating rheumatoid arthritis (RA). This study was undertaken to analyze changes in lymphocyte cell subsets during baricitinib treatment and to correlate these changes with clinical outcomes. METHODS An integrated analysis was conducted by pooling data from 3 completed phase III trials comparing placebo with baricitinib treatment (RA-BEAM, RA-BUILD, and RA-BEACON) and 1 ongoing long-term extension study (RA-BEYOND) in patients with active RA (n = 2,186). RESULTS Baricitinib treatment was associated with an early transient increase in total lymphocyte count at week 4, which returned to baseline by week 12. Transient changes within normal reference ranges in T cells and subsets were observed with baricitinib treatment, up to week 104. B cells and relevant subpopulations increased after 4 weeks of baricitinib treatment, with no further increases noted through 104 weeks of treatment. Natural killer (NK) cells temporarily increased after 4 weeks of baricitinib treatment, before decreasing below baseline levels and then stabilizing over time. With baricitinib treatment, few correlations were observed between changes in lymphocyte subsets and clinical end points, and most correlations were also observed within the placebo group. A modest potential association between low NK cell numbers and treatment-emergent infections was observed in the baricitinib 4 mg/day treatment group, but not for serious infections or herpes zoster. CONCLUSION Overall, these findings demonstrate that changes in lymphocyte subsets were largely within normal reference ranges across the baricitinib phase III RA clinical program and were not associated with increased risk of serious infections.

Abstract
Aims Filgotinib (GS‐6034, formerly GLPG0634) is an oral, selective Janus kinase 1 (JAK1) inhibitor that showed early response and sustained efficacy in patients with rheumatoid arthritis and with Crohn's disease. The aim of the present study was to investigate the impact of age and renal impairment (RI) on the pharmacokinetics (PK) of filgotinib and its main metabolite. Methods The effect of age was assessed in two groups of 10 elderly healthy subjects (65–74 and ≥75 years of age) and a control group of 10 younger healthy subjects (40–50 years of age). The impact of RI was investigated in three groups of subjects with mild (n = 6), moderate (n = 6) and severe (n = 3) RI [estimated glomerular filtration rate (eGFR) 60–89, 30–59 and 15–29 ml min–1 1.73 m–2, respectively] and a control group (n = 9) with normal renal function (eGFR ≥90 ml min–1 1.73 m–2). The PK of filgotinib and its metabolite were evaluated following filgotinib 100 mg once‐daily doses for 10 days. Results At steady state, the exposure [area under the concentration–time curve over the dosing interval (AUC0–24 h)] of filgotinib and its metabolite was moderately higher (1.45‐ and 1.33‐fold, respectively) in the elderly subjects (≥75 years) compared with younger subjects. Renal clearance for filgotinib and its metabolite decreased with the degree of RI, leading to a maximum increase in AUC0–24 h of 1.54‐fold for filgotinib and 2.74‐fold for the metabolite in subjects with severe RI. Filgotinib was generally safe and well tolerated. Conclusions Age and mild to moderate impairment of renal function had limited impact on the PK of filgotinib. In subjects with severe RI, the exposure to the metabolite of filgotinib was elevated, consistent with its renal elimination pathway.

Abstract
IMPORTANCE Rheumatoid arthritis (RA) occurs in about 5 per 1000 people and can lead to severe joint damage and disability. Significant progress has been made over the past 2 decades regarding understanding of disease pathophysiology, optimal outcome measures, and effective treatment strategies, including the recognition of the importance of diagnosing and treating RA early. OBSERVATIONS Early diagnosis and treatment of RA can avert or substantially slow progression of joint damage in up to 90% of patients, thereby preventing irreversible disability. The development of novel instruments to measure disease activity and identify the presence or absence of remission have facilitated new treatment strategies to arrest RA before joints are damaged irreversibly. Outcomes have been improved by recognizing the benefits of early diagnosis and early therapy with disease-modifying antirheumatic drugs (DMARDs). The treatment target is remission or a state of at least low disease activity, which should be attained within 6 months. Methotrexate is first-line therapy and should be prescribed at an optimal dose of 25 mg weekly and in combination with glucocorticoids; 40% to 50% of patients reach remission or at least low disease activity with this regimen. If this treatment fails, sequential application of targeted therapies, such as biologic agents (eg, tumor necrosis factor [TNF] inhibitors) or Janus kinase inhibitors in combination with methotrexate, have allowed up to 75% of these patients to reach the treatment target over time. New therapies have been developed in response to new pathogenetic findings. The costs of some therapies are considerable, but these costs are decreasing with the advent of biosimilar drugs (drugs essentially identical to the original biologic drugs but usually available at lower cost). CONCLUSIONS AND RELEVANCE Scientific advances have improved therapies that prevent progression of irreversible joint damage in up to 90% of patients with RA. Early treatment with methotrexate plus glucocorticoids and subsequently with other DMARDs, such as inhibitors of TNF, IL-6, or Janus kinases, improves outcomes and prevents RA-related disability. A treat-to-target strategy aimed at reducing disease activity by at least 50% within 3 months and achieving remission or low disease activity within 6 months, with sequential drug treatment if needed, can prevent RA-related disability.

Abstract
BACKGROUND Upadacitinib is a selective inhibitor of Janus kinase 1 and was efficacious in phase 2 studies in patients with moderate-to-severe rheumatoid arthritis. We aimed to assess the efficacy of upadacitinib in patients with inadequate response to conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs). METHODS This study is a double-blind, placebo-controlled trial at 150 sites in 35 countries. We enrolled patients aged 18 years or older with active rheumatoid arthritis for 3 months or longer, who had received csDMARDs for at least 3 months with a stable dose for at least 4 weeks before study entry, and had an inadequate response to at least one of the following csDMARDs: methotrexate, sulfasalazine, or leflunomide. Using interactive response technology, we randomly assigned patients receiving stable background csDMARDs (2:2:1:1) to receive a once-daily extended-release formulation of upadacitinib 15 mg or 30 mg, or placebo, for 12 weeks. Patients, investigators, and the funder were masked to allocation. After 12 weeks, patients taking placebo received 15 mg or 30 mg of upadacitinib once daily, according to the prespecified randomisation assignment. The primary endpoints were the proportion of patients at week 12 who achieved 20% improvement in American College of Rheumatology criteria (ACR20), and a 28-joint disease activity score using C-reactive protein (DAS28[CRP]) of 3·2 or less. We did efficacy analyses in the full analysis set of all randomly assigned patients who received at least one dose of study drug, and used non-responder imputation for assessment of the primary outcomes. This study is registered with ClinicalTrials.gov, number NCT02675426. FINDINGS Between Dec 17, 2015, and Dec 22, 2016, 1083 patients were assessed for eligibility, of whom 661 were recruited and randomly assigned to receive upadacitinib 15 mg (n=221), upadacitinib 30 mg (n=219), or placebo (n=221). All patients received at least one dose of study drug, and 618 (93%) completed 12 weeks of treatment. At week 12, ACR20 was achieved by 141 (64%; 95% CI 58-70) of 221 patients receiving upadacitinib 15 mg and 145 (66%; 60-73) of 219 patients receiving upadacitinib 30 mg, compared with 79 (36%; 29-42) of 221 patients receiving placebo (p<0·0001 for each dose vs placebo). DAS28(CRP) of 3·2 or less was met by 107 (48%; 95% CI 42-55) patients receiving upadacitinib 15 mg and 105 (48%; 41-55) patients receiving upadacitinib 30 mg, compared with 38 (17%; 12-22) patients receiving placebo (p<0·0001 for each dose vs placebo). Adverse events were reported in 125 (57%) of 221 patients receiving upadacitinib 15 mg, 118 (54%) of 219 patients receiving upadacitinib 30 mg, and 108 (49%) of 221 patients receiving placebo. The most frequently reported adverse events (≥5% of patients in any group) were nausea (16 [7%] of 221 in the upadacitinib 15 mg group; three [1%] of 219 in the upadacitinib 30 mg group; and seven [3%] of 221 in the placebo group), nasopharyngitis (12 [5%]; 13 [6%]; and nine [4%]), upper respiratory tract infection (12 [5%]; 12 [5%]; and nine [4%]), and headache (nine [4%]; seven [3%]; and 12 [5%]). More infections were reported for upadacitinib (64 [29%] of 221 patients receiving 15 mg and 69 [32%] of 219 patients receiving 30 mg) versus placebo (47 [21%] of 221 patients). There were three herpes zoster infections (one [<1%] in the placebo group, one [<1%] in the upadacitinib 15 mg group, and one [<1%] in the upadacitinib 30 mg group) and one primary varicella zoster virus infection (one [<1%] in the upadacitinib 30 mg group), two malignancies (both in the upadacitinib 30 mg group), one adjudicated major adverse cardiovascular event (in the upadacitinib 30 mg group), and five serious infections (one [<1%] in the placebo group, one [<1%] in the upadacitinib 15 mg group, three [1%] in the upadacitinib 30 mg group). No deaths were reported during the trial. INTERPRETATION Patients with moderately to severely active rheumatoid arthritis who received upadacitinib (15 mg or 30 mg) in combination with csDMARDs showed significant improvements in clinical signs and symptoms.

Abstract
BACKGROUND Phase 2 studies with upadacitinib, a selective Janus kinase 1 (JAK1) inhibitor, have shown safety and efficacy in the treatment of patients with active rheumatoid arthritis. We did this study to further assess the safety and efficacy of upadacitinib in patients with an inadequate response to biologic disease-modifying anti-rheumatic drugs (bDMARDs). METHODS We did this double-blind, randomised controlled phase 3 trial at 153 sites in 26 countries. Patients were aged 18 years or older, had active rheumatoid arthritis and previous inadequate response or intolerance to bDMARDs, and were receiving concomitant background conventional synthetic DMARDS (csDMARDs). We randomly assigned patients (2:2:1:1) by interactive response technology to receive once-daily oral extended-release upadacitinib 15 mg or 30 mg or placebo for 12 weeks, followed by upadacitinib 15 mg or 30 mg from week 12 onwards. The two separate primary endpoints were the proportions of patients achieving a 20% improvement in American College of Rheumatology criteria (ACR20) at week 12 and the proportion of patients achieving a 28-joint disease activity score using C-reactive protein (DAS28[CRP]) of 3·2 or less at week 12. Efficacy and safety analyses were done in the modified intention-to-treat population of all patients who received at least one dose of study drug. Data are presented up to week 24 of this ongoing study. The trial is registered with ClinicalTrials.gov (NCT02706847). FINDINGS Between March 15, 2016, and Jan 10, 2017, 499 patients were randomly assigned (n=165 upadacitinib 15 mg; n=165 upadacitinib 30 mg; n=85 placebo then upadacitinib 15 mg; and n=84 placebo then upadacitinib 30 mg) and one patient was withdrawn from the 15 mg upadacitinib group before the start of study treatment. Mean disease duration was 13·2 years (SD 9·5); 235 (47%) of 498 patients had received one previous bDMARD, 137 (28%) had received two, and 125 (25%) had received at least three; 451 (91%) patients completed treatment up to week 12 and 419 (84%) patients completed treatment up to week 24. At week 12, ACR20 was achieved by 106 (65%; 95% CI 57-72) of 164 patients receiving upadacitinib 15 mg and 93 (56%; 49-64) of 165 patients receiving upadacitinib 30 mg compared with 48 (28%; 22-35) of 169 patients receiving placebo (p<0·0001 for each dose vs placebo). DAS28(CRP) of 3·2 or less was achieved by 71 (43%; 95% CI 36-51) of 164 patients receiving upadacitinib 15 mg and 70 (42%; 35-50) of 165 patients receiving upadacitinib 30 mg versus 24 (14%; 9-20) of 169 patients receiving placebo (p<0·0001 for each dose vs placebo). Up to week 12, overall numbers of patients with adverse events were similar for the placebo group (95 [56%] of 169) and the upadacitinib 15 mg group (91 [55%] of 164), but higher in the upadacitinib 30 mg group (111 [67%] of 165). At week 12, the most common adverse events occurring in at least 5% of patients in any treatment group were upper respiratory tract infection (13 [8%] of 169 in the placebo group; 13 [8%] of 164 in the upadacitinib 15 mg group; ten [6%] of 165 in the upadacitinib 30 mg group), nasopharyngitis (11 [7%]; seven [4%]; nine [5%]), urinary tract infection (ten [6%]; 15 [9%]; nine [5%]), and worsening of rheumatoid arthritis (ten [6%]; four [2%]; six [4%]). The number of patients with serious adverse events was higher in the upadacitinib 30 mg group (12 [7%]) than in the upadacitinib 15 mg group (eight [5%]); no serious adverse events were reported in patients receiving placebo. More patients in the upadacitinib 30 mg group had serious infections, herpes zoster, and adverse events leading to discontinuation than in the upadacitinib 15 mg and placebo groups. During the placebo-controlled phase of the study, one case of pulmonary embolism, three malignancies, one major adverse cardiovascular event, and one death were reported in patients receiving upadacitinib; none were reported in patients receiving placebo. INTERPRETATION Both doses of upadacitinib led to rapid and significant improvements compared with placebo over 12 weeks in patients with refractory rheumatoid arthritis. FUNDING AbbVie Inc.
