Abstract
BACKGROUND AND AIMS There is an unmet need for the treatment of perianal fistulizing Crohn's disease [PFCD]. This study evaluated the efficacy and safety of the Janus kinase 1 preferential inhibitor filgotinib, for the treatment of PFCD. METHODS This phase 2, double-blind, multicentre trial enrolled adults with PFCD and prior treatment failure. Participants were randomized [2:2:1] to receive filgotinib 200 mg, filgotinib 100 mg, or placebo once-daily orally for up to 24 weeks. The primary endpoint was combined fistula response [reduction from baseline of at least one draining external opening determined by physical assessment, and no fluid collections >1 cm on pelvic magnetic resonance imaging (MRI)] at week 24. RESULTS Between April 2017 and July 2020, 106 individuals were screened and 57 were randomized. Discontinuations were lowest in the filgotinib 200 mg group [3/17 (17.6%) versus 13/25 (52.0%) for filgotinib 100 mg and 9/15 (60.0%) for placebo]. The proportion of participants who achieved a combined fistula response at week 24 was 47.1% [8/17; 90% confidence interval (CI) 26.0, 68.9%] in the filgotinib 200 mg group, 29.2% [7/24; 90% CI 14.6, 47.9%] in the filgotinib 100 mg group, and 25.0% [3/12; 90% CI 7.2, 52.7%] in the placebo group. Serious adverse events occurred more frequently with filgotinib 200 mg [5/17 (29.4%)] than with placebo [1/15 (6.7%)]. There were no treatment-related serious adverse events or deaths. CONCLUSIONS Filgotinib 200 mg was associated with numerical reductions in the number of draining perianal fistulas based on combined clinical and MRI findings compared with placebo, and was generally well tolerated.

Abstract
BACKGROUND AND AIMS Maintenance treatment for ulcerative colitis may be discontinued for multiple reasons. This post hoc analysis assessed the efficacy and safety of re-treatment with filgotinib, an oral, once-daily, Janus kinase 1 preferential inhibitor, in the phase 2b/3 SELECTION trial and its long-term extension [LTE] study in ulcerative colitis. METHODS Partial Mayo Clinic Score [pMCS] response and remission were evaluated in patients who received induction with filgotinib 200 mg [FIL200] or 100 mg [FIL100], were randomized to treatment withdrawal [placebo] during maintenance, and following disease worsening, were re-treated with open-label FIL200 in the LTE study. Factors were evaluated for association with pMCS remission at LTE week 12, and safety outcomes were reported. RESULTS Analyses included 86 patients [FIL200: n = 51; FIL100: n = 35]. Median time to disease worsening following treatment withdrawal was 15.1 weeks (95% confidence interval [CI]: 9.1-18.7) for FIL200-induced patients and 9.6 weeks [95% CI: 6.3-12.0] for FIL100-induced patients. Three-quarters [75%] of patients achieved a pMCS response within 4-5 weeks of re-treatment in both groups. At LTE week 48, pMCS remission was achieved by 45.1% and 51.4% of FIL200- and FIL100-induced patients, respectively. Factors independently associated with restoring efficacy included no concomitant use of corticosteroids at induction baseline, and high albumin levels, pMCS remission, and endoscopic score at maintenance baseline. No new safety signals were reported among re-treated patients. CONCLUSIONS In induction responders, re-treatment with FIL200 following temporary withdrawal from therapy restores response and/or remission in the majority of patients within 12 weeks. Re-treatment is well-tolerated. ClinicalTrials.gov identifiers: NCT02914522, NCT02914535.

Abstract
Filgotinib is an oral preferential Janus kinase 1 inhibitor that demonstrated significant reductions in radiographic progression, with an acceptable tolerability and safety profile, vs placebo in patients with rheumatoid arthritis (RA) and an inadequate response to methotrexate (MTX-IR; FINCH 1) and vs MTX in MTX-naïve patients with RA (FINCH 3). International treatment guidelines identify multiple poor prognostic factors (PPFs) associated with worse disease outcomes among patients with RA. However, questions remain both about the clinical utility of considering PPFs and about which PPFs should drive treatment decisions. Additionally, the role of radiographic findings in clinical practice continues to be discussed and to evolve. This review examines radiographic results from post hoc analyses of phase 3 trials of filgotinib that examined subgroups with 4 PPFs or with baseline estimated rapid radiographic progression (e-RRP). In MTX groups, there were trends toward greater progression among patients with 4 PPFs or e-RRP, suggesting these subgroups may comprise a higher-risk population. Results show general consistency for the efficacy of filgotinib 200 mg plus MTX vs placebo plus MTX/MTX monotherapy on radiographic assessments, including change from baseline in modified total Sharp score and proportions without radiographic progression, even among MTX-IR or MTX-naïve patients with 4 PPFs or e-RRP who may be at higher risk of bone damage. Multivariate analysis identified multiple factors associated with baseline e-RRP status. This summary of the current understanding of benefits associated with filgotinib on radiographic progression and the relevance of baseline factors to these benefits may help inform treatment decisions for patients facing high risk of radiographic progression.

Abstract
INTRODUCTION This post hoc analysis of the phase 3 rheumatoid arthritis (RA) filgotinib clinical trial program assessed the effect of filgotinib on body mass index (BMI) in patients with RA and the impact of BMI on the efficacy and safety of filgotinib. METHODS FINCH 1-3 were randomized, double-blind, active- or placebo-controlled phase 3 trials of filgotinib 100 and 200 mg in patients with RA (N = 3452). BMI assessments included the mean change from baseline in BMI and the proportion of patients whose BMI increased by incremental thresholds. Efficacy measures included American College of Rheumatology (ACR) 20/50/70 response and low disease activity/remission according to Disease Activity Score 28 using C-reactive protein. The exposure-adjusted incident rate (EAIR) of adverse events (AEs) was assessed by baseline BMI, using integrated data from the FINCH 1-4 and the phase 2 DARWIN 1-3 studies (total filgotinib exposure = 8085 patient-years). RESULTS Mean change from baseline in BMI over time was similar across treatment arms. In most patients, BMI increased by ≤ 1 or 2 kg/m2 at both weeks 12 and 24, regardless of treatment group or baseline BMI; few patients had increases of ≥ 4 kg/m2. For most efficacy measures, filgotinib 200 mg was more efficacious than filgotinib 100 mg or active comparators or placebo across BMI subgroups. For the higher filgotinib dose, the EAIR of serious treatment-emergent AEs, venous thrombotic and embolic events, and major adverse cardiovascular events increased with increasing BMI. CONCLUSIONS Filgotinib did not lead to substantial changes in BMI, and BMI did not appear to affect the efficacy of filgotinib.

Abstract
This point of view explores the safety concerns of Janus kinase inhibitors (JAK-Is), used in treating rheumatoid arthritis (RA) and other rheumatologic conditions. Increasing evidence shows that JAK-Is may elevate the risk of venous thromboembolism (VTE), especially pulmonary embolism. This fact has prompted the European Medicines Agency to advise cautious use of these drugs in patients over 65, smokers, and those at risk of cardiovascular issues or cancer. The paper analyses the evidence on the association between VTE risk and RA and whether different JAK-Is pose different risks. It also probes the link between VTE, lipids, and JAK inhibition, noting that JAK-Is can alter HDL and LDL levels. On the other hand, some evidence indicates that tighter LDL-cholesterol control could mitigate VTE risk, particularly pulmonary embolism. Moreover, data from trials show little attention to treating this main cardiovascular and VTE risk factor in rheumatological patients. Although the lipid paradox theory emphasizes the U-shaped relationship between LDL cholesterol and cardiovascular risk in patients with RA, uncontrolled levels of clinically relevant LDL cholesterol remain closely linked to cardiovascular and VTE risk. In conclusion, high-potency statins could help to manage the increased cardiovascular and VTE risk concomitant to JAK-Is treatment in rheumatologic patients without depriving them of the best therapeutic choice and, in addition, reducing the inherent risk associated with the disease.

Abstract
BACKGROUND AND AIMS The efficacy of new therapies for ulcerative colitis [UC] is usually influenced by previous biologic use. These post hoc analyses of SELECTION, a placebo-controlled phase 2b/3 trial in patients with moderately to severely active UC, evaluated the efficacy of filgotinib, an oral Janus 1 kinase preferential inhibitor, with respect to prior biologic failure. METHODS The effect of filgotinib 200 mg (FIL200) relative to placebo was compared in biologic-naïve and biologic-failed patient groups, and in further subgroups by number of failed biologics [1 or >1], biologic mechanism of action [MoA] classes [1 or 2] and tumour necrosis factor [TNF] antagonists [1 or >1]. Odds ratios [ORs] for clinical remission at week 10 [induction] and hazard ratios [HRs] for protocol-specific disease worsening [PSDW] from week 11 to week 58 [maintenance] were calculated. RESULTS At week 10, FIL200-treated patients were more likely to achieve clinical remission than placebo-treated patients in the biologic-naïve (OR [95% confidence interval, CI]: 1.98 [1.14-3.44]) and biologic-failed (3.91 [1.33-11.48]) groups. During maintenance, FIL200-treated patients had a reduced risk of PSDW in the biologic-naïve (HR [95% CI]: 0.22 [0.11-0.44]) and biologic-failed (0.22 [0.12-0.40]) groups, and in all biologic-failed subgroups (except >1 TNF antagonist failure). The data suggest that the likelihood of PSDW at week 58 increased with increasing numbers of failed biologics. CONCLUSIONS FIL200 induced and maintained benefits relative to placebo regardless of previous biologic use; however, the estimated therapeutic benefit was greatest in biologic-naïve patients and patients previously treated with one biologic or biologic MoA class.

Abstract
INTRODUCTION Janus kinase (JAK) inhibitors are an emerging class of small-molecule drugs, providing targeted therapy for a variety of diseases, and have made their way into the treatment of armamentarium of ulcerative colitis (UC) in recent years. AREAS COVERED This review focuses on the pharmacokinetics, safety, and efficacy of selective JAK1 inhibitors in the treatment of moderate-to-severe UC. The PubMed database and clinicaltrials.gov were consulted using keywords - further expanded in the methods section. The search was focused on full-text publications in English. No publication date restrictions were imposed. EXPERT OPINION JAK1 inhibitors are small-molecule drugs used in the treatment of ulcerative colitis and other immune mediated inflammatory diseases. They are orally bioavailable and have a rapid mechanism of action and no immunogenicity. JAK inhibitors can be used for the management of both naïve patients and biological-experienced patients.Particular attention should be paid to elderly patients or those with cardiovascular or oncological risk factors, in whom JAK inhibitors should be recommended only if no alternatives are available. In addition, JAK inhibitors have the potential to be combined with other biological drugs or small molecules for the management of difficult-to-treat cases.

Abstract
INTRODUCTION Psoriatic arthritis (PsA) is a chronic inflammatory disease affecting about one-third of subjects with psoriasis. Several treatment modalities targeting Janus Kinase pathways and intracellular inflammatory cascade are now available and under clinical investigation to treat this disease. AREAS COVERED This review describes ongoing and recently completed phase 2 and 3 Randomized Clinical Trials (RCTs) evaluating the efficacy and safety of approved JAK (Tofacitinib and Upadacitinib) and investigational JAK inhibitors (JAK1 inhibitors: Filgotinib and Ivarmacitinib (SHR0302); TYK2 inhibitors: Brepocitinib (PF-06700841) Deucravacitinib (BMS-986165), and NDI-034858) in PsA through February 2023. EXPERT OPINION Current standard of care has significantly improved the quality of life in PsA. Recently approved JAK inhibitors for PsA have addressed many of the unmet needs of PsA, particularly of those with severe phenotypes. Preliminary results from several RCTs have reported good and fast efficacy and an acceptable safety profile of investigational JAK inhibitors in PsA. Additional clinical trials and long-term outcome data on these agents are necessary for increasing available therapeutic options for PsA.

Abstract
BACKGROUND Janus kinase inhibitors (JAKis) is a new therapeutic class in autoimmune and inflammatory diseases. Four molecules are approved in rheumatoid arthritis (RA) in Europe. Recently, questions have raised about adverse events. In this context, a synthesis of the efficacy data of JAKis in RA is of use. METHOD We performed a literature review based on published articles about efficacy of JAKis in RA, including clinical trials, registries, retrospective and prospective cohorts as well as database analysis. RESULTS Based on the phase III clinical trials, JAKis are effective in comparison to placebo, methotrexate and tumour necrosis factor inhibitors. Based on registries, cohorts and post hoc analysis of phase III clinical trials, several parameters might modulate the efficacy of JAKis: the serological status, a short duration of the disease or the presence of poor prognostic factors. Preliminary data suggest that early ultrasonographic evaluation might help to predict the medium-term progression. CONCLUSION Some clinical, biological and imaging parameters seem to influence the response to JAKis and should be evaluated in larger studies. In addition to factors that might influence the efficacy of JAKis, the safety profile and risk factors should be considered before initiating JAKis in a patient.

Abstract
BACKGROUND AND AIMS Corticosteroid-free remission is an important treatment goal for patients with ulcerative colitis [UC]. The corticosteroid-sparing effects of filgotinib, an oral, Janus kinase 1 preferential inhibitor, were assessed in SELECTION, a placebo-controlled, phase 2b/3 trial in moderately to severely active UC. METHODS These post hoc analyses assessed 1-, 3-, 6-, and 8-month rates of corticosteroid-free clinical remission at Week 58 and change in median daily prednisone-equivalent dose over time. A matching-adjusted indirect comparison [MAIC] of maintenance studies assessed corticosteroid-free remission with filgotinib 200 mg, intravenous vedolizumab, subcutaneous vedolizumab, and oral tofacitinib. RESULTS The Maintenance Study full analysis set included 199 patients receiving filgotinib 200 mg and 98 receiving placebo. Among patients receiving corticosteroids at Maintenance Study baseline, at Week 58, 30.4%, 29.3%, 27.2%, and 21.7% receiving filgotinib had been in corticosteroid-free remission for ≥1, ≥3, ≥6, or ≥8 months, respectively, versus 6.4% receiving placebo across thresholds [p <0.05]. Median daily prednisone-equivalent dose decreased from 17.5 mg/day to 10.0 mg/day with filgotinib treatment during the Maintenance Study. Based upon the MAIC, filgotinib was associated with greater likelihood of corticosteroid-free clinical remission versus intravenous vedolizumab (odds ratio [OR], 15.2; 95% confidence interval [CI], 1.6-139.9; p <0.05]) and similar odds to subcutaneous vedolizumab [OR, 3.8; CI, 0.2-63.8; p = 0.36] in biologic-naïve patients, and similar odds to tofacitinib overall [OR, 2.0; 0.4-9.1; p = 0.39]. CONCLUSIONS Filgotinib 200 mg demonstrated corticosteroid-sparing effects and maintained corticosteroid-free clinical remission in patients with UC. MAIC results should be interpreted cautiously given the large CIs and differences in study design and patient populations. [ClinicalTrials.gov: NCT02914522].

Abstract
BACKGROUND Administration of Janus kinase (JAK) inhibitors and biological disease-modifying antirheumatic drugs has dramatically improved even the clinical outcomes in patients with rheumatoid arthritis (RA) and an inadequate response to methotrexate (MTX). Dysregulation of JAK-STAT pathways via overproduction of cytokines, such as interleukin-6, is involved in the pathogenesis of RA. Filgotinib is a selective JAK1 inhibitor pending approval for use in RA. By inhibition of the JAK-STAT pathway, filgotinib is effective in suppressing disease activity and preventing the progression of joint destruction. Similarly, interleukin-6 inhibitors such as tocilizumab also inhibit the JAK-STAT pathways by inhibition of interleukin-6 signaling. We present the protocol for a study that will evaluate whether the effectiveness of filgotinib monotherapy is non-inferior to that of tocilizumab monotherapy in RA patients with an inadequate response to MTX. METHODS This study is an interventional, multicenter, randomized, open-label, parallel-group, and non-inferiority clinical trial with a 52-week follow-up. Study participants will be 400 RA patients with at least moderate disease activity during treatment with MTX. Participants will be randomized in a 1:1 ratio to administer filgotinib monotherapy or subcutaneous tocilizumab monotherapy switched from MTX. We will evaluate disease activity by measuring clinical disease activity indices and by using musculoskeletal ultrasound (MSUS). The primary endpoint is the proportion of patients who achieve an American College of Rheumatology 50 response at week 12. Secondary endpoints are changes from baseline in the MSUS scores. We will also comprehensively analyze serum levels of multiple biomarkers, such as cytokines and chemokines. DISCUSSION The study results are expected to show the non-inferiority of the effectiveness of filgotinib monotherapy to that of tocilizumab monotherapy in RA patients with inadequate response to MTX. The strength of this study is its prospective evaluation of therapeutic efficacy using not only clinical disease activity indices, but also MSUS, which accurately and objectively evaluates disease activity at the joint level among patients drawn from multiple centers with a standardized evaluation by MSUS. We will evaluate the effectiveness of both drugs by integrating multilateral assessments-clinical disease activity indices, MSUS findings, and serum biomarkers.

Abstract
INTRODUCTION Global clinical trials in rheumatoid arthritis (RA) often do not recruit enough patients from diverse racial and ethnic backgrounds to identify any potential differences in treatment outcome across such groups. To overcome this limitation, using data from five previous clinical trials and two ongoing trial extensions, this study aimed to assess the efficacy and safety of filgotinib in patients with RA across geographic regions. METHODS This was a post hoc, exploratory analysis of data from male and female patients with RA meeting the 2010 RA criteria as defined by the American College of Rheumatology (ACR) and European Alliance of Associations for Rheumatology. Data were analyzed from phase 2 (DARWIN 1-2) and phase 3 (FINCH 1-3) clinical trials, as well as two long-term extension studies (DARWIN 3, FINCH 4), of filgotinib. Efficacy endpoints included ACR 20%/50%/70% improvement (ACR20/50/70) responses, disease activity score in 28 joints using C-reactive protein [DAS28(CRP)], Clinical Disease Activity Index scores, Boolean remission, and change from baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI). Safety data were presented as exposure-adjusted incidence rates per 100 patient-years of exposure of treatment-emergent adverse events. RESULTS Compared with placebo, at week 12 a greater proportion of patients receiving filgotinib 200 mg (FIL200) or 100 mg (FIL100) achieved ACR20 (p < 0.01), with similar outcomes in most regions. Overall, the reduction in HAQ-DI with FIL200 or FIL100 was greater than with placebo (p < 0.05) at week 12. Compared with placebo, at week 24 the proportions of patients achieving DAS28(CRP) ≤ 3.2 were greater for both doses of FIL, as seen in most regions (p < 0.01). Safety outcomes did not indicate regional or ethnic differences in the safety profile of filgotinib. CONCLUSION Filgotinib efficacy and safety in patients with RA were generally consistent across geographic regions.

Abstract
INTRODUCTION This exploratory analysis of FINCH 1 (NCT02889796) examined filgotinib (FIL) efficacy and safety in a subgroup of patients with rheumatoid arthritis (RA) and inadequate response to methotrexate (MTX; MTX-IR) who had four poor prognostic factors (PPFs). METHODS Patients with MTX-IR received placebo up to week (W)24 or FIL200 mg, FIL100 mg, or adalimumab up to W52; all received MTX. Efficacy and safety data were stratified by four PPFs versus fewer than four PPFs: seropositivity, high-sensitivity C-reactive protein (CRP) ≥ 6 mg/L, Disease Activity Score in 28 joints with CRP > 5.1, and erosions on X-rays. RESULTS At baseline, 687/1755 patients had four PPFs. At W12, whether with four PPFs or fewer than four PPFs, response rates on all American College of Rheumatology (ACR) measures were significantly greater with FIL200 and FIL100 versus placebo. At W52, FIL200 ACR20/50/70 response rates remained at least numerically higher versus adalimumab in both subgroups. At W52, FIL200 reduced modified total Sharp score (mTSS) change versus adalimumab in patients with four or fewer than four PPFs. CONCLUSIONS In high-risk (four PPFs) patients with MTX-IR RA, FIL200 and FIL100 showed similar reductions in disease activity versus placebo at W12 as in patients with fewer than four PPFs. mTSS in patients receiving FIL200 changed little from W24 to W52, while that in patients receiving FIL100 progressed comparably to patients who received adalimumab. Tolerability was comparable across treatment arms and subgroups.

Abstract
INTRODUCTION We conducted a post hoc analysis of efficacy and safety of filgotinib stratified by estimated radiographic progression rate before baseline (BL) in patients with rheumatoid arthritis (RA) who had inadequate response to methotrexate (MTX; FINCH 1; NCT02889796) or were naïve to it (FINCH 3; NCT02886728). METHODS Radiographic progression rate was BL-Modified Total Sharp Score (mTSS) divided by RA duration (BL mTSS/year); estimated rapid radiographic progression (e-RRP) was BL change in mTSS/year ≥ 5; and estimated nonrapid radiographic progression (e-NRRP) was BL mTSS/year < 5. Efficacy and safety were compared between subgroups. All p-values are nominal. RESULTS In FINCH 1 and FINCH 3, 558/1755 (31.8%) and 787/1249 (63.0%) patients, respectively, had BL e-RRP. BL characteristics were generally similar between subgroups within each trial. At week (W) 24, in FINCH 1, proportions achieving a Disease Activity Score 28 for rheumatoid arthritis with C-reactive protein < 2.6 were significantly greater with filgotinib 200 (FIL200) and 100 mg (FIL100) versus placebo among e-RRP and e-NRRP subgroups. In each study, proportions of FIL-treated patients achieving Clinical Disease Activity Index ≤ 2.8 and Simple Disease Activity Index ≤ 3.3 were similar between subgroups. In FINCH 3, disease activity measures were at least numerically improved among patients receiving FIL versus MTX monotherapy. At W24, mTSS changes from BL (CFB) were greater among patients with e-RRP in FINCH 1 and FINCH 3 versus e-NRRP (0.81 versus 0.19, p = 0.001; 0.67 versus 0.25, p = 0.31, respectively). At W52, in FINCH 1, mTSS CFBs were smaller among e-RRP patients treated with FIL200 (0.40; p < 0.001) and FIL100 (0.77; p = 0.024) versus adalimumab (ADA; 1.46). In FINCH 3 at W52, mTSS CFBs were significantly smaller with FIL200 versus MTX among e-RRP patients. Rates of treatment-emergent adverse events (AEs) were comparable between subgroups and across treatment arms. CONCLUSIONS Patients with previous e-RRP who received standard care tended to progress radiographically. FIL200 demonstrated persistent, consistent benefit for disease activity control among e-RRP and e-NRRP subgroups, and AE profiles were similar between subgroups. Although filgotinib efficacy was somewhat reduced among patients with e-RRP, filgotinib treatment slowed radiographic progression in both subgroups.

Abstract
INTRODUCTION Rheumatoid Arthritis (RA) remains a challenge for rheumatologists and patients despite implementation of intensive treat-to-target strategies in shared decision with patients and an increasing availability of drugs. Janus kinase inhibitors (JAKi) are a new generation of oral targeted drugs. Filgotinib preferentially inhibits JAK1 and is the latest JAKi to be approved for use in RA. AREAS COVERED This narrative review focuses on drug characteristics, efficacy, and safety of filgotinib in patients with RA, summarizing available literature. Trial data are detailed, put into perspective for practice and discussed in regulatory perspective. EXPERT OPINION Preclinical studies demonstrate preferential inhibition of JAK1 and a promising pharmacokinetic profile with few drug-drug interactions. Increase in hemoglobin in line with preferential inhibition of JAK1 over JAK2 is seen in early-phase clinical trials. A phase III program demonstrates efficacy in several disease stages, numerically higher with 200 mg versus 100 mg daily. In the overall RA population such dose-related effect is not observed for safety except for herpes zoster and increases in lipids and creatine phosphokinase. This reassuring safety profile is to be confirmed in future practice. It also needs to be unraveled if JAK1 preferential inhibition plays a key role in this safety profile.

Abstract
OBJECTIVE Characterize safety of the Janus kinase-1 preferential inhibitor filgotinib (FIL) in Japanese patients with moderately to severely active rheumatoid arthritis (RA). METHODS Data from three Phase 3 trials (NCT02889796, NCT02873936, and NCT02886728) and a long-term extension (NCT03025308) through September 2019 were integrated; patients received ≥1 dose of FIL 200 (FIL200) or 100 mg (FIL100) daily, or placebo (PBO). We calculated exposure-adjusted incidence rates (EAIRs) per 100 patient-years FIL exposure (100PYE) for treatment-emergent adverse events (TEAEs) and adverse events of special interest. RESULTS Among 3691 total patients and 6080.7 PYE, 229 Japanese patients received FIL for 311.4 PYE (median 1.5, maximum 2.5 years). During the 12-week PBO-controlled period, serious TEAEs and TEAEs leading to study drug disruption were comparable between FIL and PBO. Serious infection rates were 1.9%, 0%, and 2% for FIL200, FIL100, and PBO during the PBO-controlled period; long-term FIL200 and FIL100 EAIRs were 3.8 and 2.1/100PYE. No herpes zoster (HZ) or major adverse cardiovascular events (MACEs) occurred during the PBO-controlled period; long-term FIL200 and FIL100 EAIRs were 3.0 and 2.1/100PYE (HZ) and 0.6 and 0/100PYE (MACE). CONCLUSION Long-term FIL treatment (median 1.5, maximum 2.5 years exposure) was well tolerated at 100- and 200-mg doses in Japanese patients with RA.

Abstract
BACKGROUND/AIMS The safety and efficacy of filgotinib, a once-daily oral Janus kinase 1 preferential inhibitor, were evaluated in Japanese patients with ulcerative colitis (UC) in the phase 2b/3 SELECTION trial. METHODS SELECTION (NCT02914522) was a randomized, placebo-controlled trial comprising 2 induction studies and a maintenance study. Adults with moderately to severely active UC were randomized in induction study A (biologic-naïve) or B (biologic-experienced) to receive filgotinib 200 mg, 100 mg, or placebo once daily for 11 weeks. Patients in clinical remission or Mayo Clinic score response at week 10 entered the 47-week maintenance study. Efficacy and safety outcomes were assessed in Japanese patients enrolled in Japan. RESULTS Overall, 37 and 72 Japanese patients were enrolled in Japan in induction studies A and B, respectively, and 54 entered the maintenance study. Numerically higher proportions of filgotinib 200 mg-treated than placebo-treated patients achieved clinical remission in induction study A (4/15 [26.7%] vs. 0/6 [0%]) and the maintenance study (5/20 [25.0%] vs. 0/9 [0%]), but not induction study B (1/29 [3.4%] vs. 1/14 [7.1%]). Both doses were well tolerated, and no new safety signals were noted. Herpes zoster was reported in 1 filgotinib 200 mg-treated patient in each of induction study A (2.3%, 1/44) and the maintenance study (5.0%, 1/20). CONCLUSIONS These data, alongside those of the overall SELECTION population, suggest the potential of filgotinib 200 mg as a viable treatment option for Japanese patients with UC. Owing to small patient numbers, data should be interpreted cautiously.

Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory disease whose natural history leads to articular and extra-articular damage. Both cardiovascular risk and malignancy risk results higher in RA patients, compared to general population. Janus kinase inhibitors (JAKis) are oral targeted synthetic disease modifying antirheumatic drugs (tsDMARDs) that disrupt cytokine cascade and exert anti-inflammatory effects by interfering with signaling through the JAK-STAT intracellular pathways. A recent RCT comparing tofacitinib 5 mg twice daily, tofacitinib 10 mg twice daily and anti-TNF in rheumatoid arthritis demonstrated an increased risk of MACE HR 1.33 and cancer HR 1.49 at a follow-up of 4 years. This has led the FDA to class warnings for tofacitinib, baricitinib and upadacitinib. Cumulative RCT data, RCT extension data demonstrated a safety profile for Jak inhibitors. Conflicting data results from real life registries; the different selectivity for JAKs (JAK1, JAK2, JAK3 and Tyk2) probably determines differences in efficacy and safety profiles among the members of this group which should actually be evaluated. In order to better understand the cardiovascular and neoplastic risk linked to these class of drugs, we aim to provide a literature review on existing evidence of the safety of Jak-Inhibitors in rheumatoid arthritis.

Abstract
The validity and relevance of histologic disease activity in Crohn's disease (CD) is unclear, owing to disconnects with endoscopic pathology. Here, we explore relationships between endoscopic, histologic, and molecular activity. This post hoc analysis of the Phase 2 FITZROY trial (NCT02048618) assessed baseline and week 10 (W10) inflammation across matched ileal and colonic segments in CD patients receiving filgotinib 200 mg (n = 42) vs placebo (n = 18). Macroscopic and microscopic disease were assessed by Simple Endoscopic Score for CD ulceration subscore (uSES-CD) and Global Histologic Activity Score activity subscore (aGHAS), respectively. Molecular activity was quantified by phosphorylated signal transducer and activator of transcription (pSTAT)1 and pSTAT3 in epithelium and nonepithelium. Segments were classified as "low" or "high" activity; correlations and concordance were calculated. Logistic regression identified W10 outcome predictors. Overall, 300 segments in 60 patients were assessed. Baseline uSES-CD and aGHAS correlations were 0.72 and 0.53 in colon and ileum, respectively. pSTAT levels had poor-to-moderate concordance with uSES-CD (κ range, 0.11-0.49) but moderate-to-good concordance with aGHAS (0.43-0.77). With filgotinib vs placebo, uSES-CD and aGHAS decreased in significantly more segments with high baseline uSES-CD and aGHAS, and significantly more segments with high baseline pSTAT improved at W10. pSTAT1 was more sensitive to change than uSES-CD and aGHAS. Low baseline pSTAT3 in colon nonepithelium predicted W10 low uSES-CD (P = .044). There was better concordance between histologic and molecular disease activity associated with higher sensitivity to change vs endoscopic severity in ileocolonic CD. Our results suggest histologic activity be included in the assessment of CD inflammatory burden.

Abstract
Introduction The phase 2 MANTA and MANTA-RAy studies were developed in consultation with global regulatory authorities to investigate potential impacts of filgotinib, a Janus kinase 1 preferential inhibitor, on semen parameters in men with active inflammatory diseases. Here we describe the methods and rationale for these studies. Methods and Rationale The MANTA and MANTA-RAy studies included men (aged 21–65 years) with active inflammatory bowel disease (IBD) and rheumatic diseases, respectively. Participants had no history of reproductive health issues, and the following semen parameter values (≥ 5th percentile of World Health Organization reference values) at baseline: semen volume ≥ 1.5 mL, total sperm/ejaculate ≥ 39 million, sperm concentration ≥ 15 million/mL, sperm total motility ≥ 40% and normal sperm morphology ≥ 30%. Each trial included a 13-week, randomized, double-blind, placebo-controlled period (filgotinib 200 mg vs placebo, up to N = 125 per arm), for pooled analysis of the week-13 primary endpoint (proportion of participants with ≥ 50% decrease from baseline in sperm concentration). All semen assessments were based on two samples (≤ 14 days apart) to minimize effects of physiological variation; stringent standardization processes were applied across assessment sites. From week 13, MANTA and MANTA-RAy study designs deviated owing to disease-specific considerations. All subjects with a ≥ 50% decrease in sperm parameters continued the study in the monitoring phase until reversibility, or up to a maximum of 52 weeks, with standard of care as treatment. Overall conclusions from MANTA and MANTA-RAy will be based on the totality of the data, including secondary/exploratory measures (e.g. sperm motility/morphology, sex hormones, reversibility of any effects on semen parameters). Conclusions Despite the complexities, the MANTA and MANTA-RAy studies form a robust trial programme that is the first large-scale, placebo-controlled evaluation of potential impacts of an advanced IBD and rheumatic disease therapy on semen parameters. Trial Registration EudraCT numbers 2017-000402-38 and 2018-003933-14; ClinicalTrials.gov identifiers NCT03201445 and NCT03926195. Supplementary Information The online version contains supplementary material available at 10.1007/s12325-022-02168-4. Filgotinib is a treatment for patients with ulcerative colitis and rheumatoid arthritis, and is being studied in other inflammatory diseases. Filgotinib works by blocking Janus kinase 1, an intracellular protein involved in inflammatory signalling processes. We designed the MANTA and MANTA-RAy trials with global health agencies to find out if filgotinib decreases the quality of semen in men with active inflammatory bowel disease (ulcerative colitis or Crohn’s disease) (MANTA) or rheumatic disease (rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis or non-radiographic axial spondylitis) (MANTA-RAy). This paper describes the design of the two trials. Patients had normal sperm measurements and could not have had previous reproductive health issues. Nearly 250 patients were included in each trial. In both MANTA and MANTA-RAy, half of the patients were treated with 200 mg of filgotinib once a day for 13 weeks, and the other half with placebo. We determined if any patients had a decrease in number of sperm cells per millilitre (sperm concentration) by at least half after 13 weeks of treatment. We then monitored any patients who had such a decrease in sperm concentration for up to 52 weeks (while they received standard of care treatment) or until the decrease was reversed. The conclusions from the trials will be in a different paper and will be based on all the final data, including changes in sex hormones. This is the first large-scale clinical trial programme to measure the effect of a treatment on sperm in men with inflammatory bowel disease or rheumatic diseases.

Abstract
In the treatment of rheumatoid arthritis (RA), Janus kinase inhibitors (jakinibs) represent an emerging class of targeted therapies in addition to biologics. The number of jakinibs has been growing and as of 2020, filgotinib was the latest jakinib to enter the international market for treating RA. Filgotinib has demonstrated preferential inhibition of JAK1-dependent cytokine signaling in in vitro assays. It has been evaluated in the DARWIN (phase 2) and FINCH (phase 3) series of clinical studies for treating patients with moderately-to-severely active RA. Filgotinib received regulatory approval in Japan and Europe in September 2020, while in August 2020 the United States Food and Drug Administration requested additional data from two ongoing clinical studies assessing the potential impact of filgotinib on sperm parameters. This article will review the pharmacological properties, efficacy, and safety of filgotinib as demonstrated in clinical studies. Expert opinion will be provided on jakinibs for RA treatment from the viewpoints of basic research and clinical practice.

Abstract
Background The effects of filgotinib on patient-reported outcomes (PROs) from 3 trials in patients with active rheumatoid arthritis were investigated. Methods Methotrexate (MTX)-naïve patients received filgotinib 200 or 100 mg plus MTX (FIL200+MTX, FIL100+MTX), filgotinib 200 mg monotherapy (FIL200), or MTX monotherapy through 52 weeks (NCT02886728). Patients with inadequate response (IR) to MTX (MTX-IR) received FIL200+MTX, FIL100+MTX, adalimumab 40 mg +MTX (ADA+MTX), or placebo (PBO)+MTX (rerandomized to FIL200+MTX or FIL100+MTX at week 24) through 52 weeks (NCT02889796). Patients with IR to biologic disease-modifying antirheumatic drugs (bDMARD-IR) received FIL200 or FIL100 or PBO with background stable conventional synthetic (cs) DMARDs for up to 24 weeks (NCT02873936). PROs included Health Assessment Questionnaire-Disability Index (HAQ-DI), Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) physical/mental component summary (PCS/MCS), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue), Work Productivity and Activity Impairment Questionnaire-Rheumatoid Arthritis (WPAI-RA), and Patient Global Assessment of Disease Activity (PtGA). Data are reported as least-squares mean changes from baseline with standard error to the timepoint representing each study’s primary endpoint. All statistical comparisons are of filgotinib groups vs their respective control groups. Results At week 24, among MTX-naïve patients, change from baseline (standard deviation) in HAQ-DI was − 1.00 (0.03; P < 0.001) with FIL200+MTX, − 0.94 (0.04; P < 0.01) with FIL100+MTX, and − 0.91 (0.04; P < 0.05) with FIL200 alone compared with − 0.81 (0.03) with MTX alone. At week 12, among MTX-IR patients, change from baseline in HAQ-DI was − 0.69 (0.04; P < 0.001 vs PBO+MTX, P < 0.05 vs ADA) with FIL200+MTX, − 0.57 (0.04; P < 0.001 vs placebo) with FIL100+MTX, and − 0.60 (0.04) with ADA vs − 0.40 (0.04) with PBO+MTX. At week 12, among bDMARD-IR patients, change from baseline in HAQ-DI was − 0.50 (0.06; P < 0.001) with FIL200+csDMARD and − 0.46 (0.05; P < 0.001) with FIL100+csDMARD vs − 0.19 (0.06) with placebo+csDMARD. Changes in SF-36 PCS and MCS, FACIT-Fatigue, WPAI, and PtGA tended to favor filgotinib over PBO, MTX, and ADA. Greater proportions of patients experienced clinically meaningful differences with either dosage of FIL in combination with csDMARDs (including MTX) and with FIL200 monotherapy vs comparators. Conclusions Filgotinib provided improvements in PROs across patient populations. These findings suggest filgotinib can be an effective treatment option for patients with insufficient response to MTX or bDMARDs and patients who are MTX-naïve.

Abstract
INTRODUCTION Rheumatoid arthritis (RA) is a chronic debilitating illness, usually associated with mental health ailments. Literature reports contradictory observations about the association between recent RA pharmacotherapies and mental health. We systematically reviewed RA randomized control trials to synthesize the association between Janus kinases (JAK) inhibitors therapy and mental health. METHODS We systematically searched clinical trials of JAK inhibitor intervention reporting mental health outcomes using short form-36 (SF-36) in PubMed, Embase, and Scopus databases from inception to February 2021. We have selected the studies and extracted the data, adhering to Preferred Reporting Items of Systematic reviews and Meta-Analysis (PRISMA) guidelines. We have pooled the mean change of SF-36 mental component score (MCS) between JAK inhibitors and comparator therapy with a 95% confidence interval. RESULTS Of the 2915 searched studies for systematic review, 19 studies involving 14,323 individuals were included for the meta-analysis. The pooled mean reduction in SF-36 MCS scores (after minus before) with JAK inhibitors was 4.95 (4.41-5.48). The pooled mean difference of incremental mean change in SF-36 MCS score between JAK monotherapy and comparator was 1.53 (0.88-2.18). The improvement in SF-36 MCS scores with JAK inhibitor therapy is greater than the minimum clinically important difference (MCID) value of 2.5. However, on separate analysis with comparator drugs like methotrexate and standard treatment, the MCS scores did not exceeded the MCID value and were also not statistically significant. CONCLUSIONS JAK inhibitors results in clinically meaningful improvement in the mental health scores of the RA patients. PROSPERO REGISTRATION ID 2021 CRD42021234466.

Abstract
In 2017 the first Janus kinase (JAK) inhibitors were approved for the treatment of rheumatoid arthritis in Germany. The mode of action of JAK inhibitors differs from biologicals, as multiple cytokines are inhibited. In comparison with the treatment with biologicals, JAK inhibitors have the advantage of oral application, three of the four currently approved JAK inhibitors were superior to adalimumab in at least some of the endpoints in randomized controlled trials, they have a short half-life and have a particular efficacy in the control of pain. On the other hand, the rate of malignancies and major cardiovascular events was increased in the Oral Surveillance trial in comparison with tofacitinib and tumor necrosis factor (TNF) inhibitors but not in the CorEvitas registry and not in the phase III approval trials. The clarification of these safety discussions and the evaluation of further registry data will decide the position of JAK inhibitors in the therapeutic algorithm for rheumatoid arthritis.

Abstract
BACKGROUND AND AIMS Filgotinib is a small molecule that selectively inhibits Janus kinase [JAK] type 1. It is already approved for the treatment of rheumatoid arthritis and is being evaluated for the management of patients with moderate to severe ulcerative colitis [UC]. The purpose of this review is to provide an overview of the currently available data on filgotinib and to define how to position this new drug in the treatment algorithm of patients with UC. METHODS The Pubmed, Embase and Scopus databases were searched up to June 25, 2021 in order to identify studies reporting efficacy and safety data of filgotinib in patients with UC. RESULTS Data from a phase III study enrolling UC patients with moderate to severe disease show that filgotinib is effective with a reassuring safety profile. Filgotinib treatment is not associated with a greater risk of thrombosis and herpes zoster infections compared to other JAK inhibitors. However, animal studies reported impaired spermatogenesis and histopathological effects on male reproductive organs, making it necessary to deepen this aspect in dedicated human studies. CONCLUSIONS Filgotinib is an effective and safe drug for treatment of both biologic-naive and biologic-experienced patients with moderate to severe UC and may soon be available.

Abstract
OBJECTIVES To evaluate the efficacy and safety of filgotinib for Japanese patients with rheumatoid arthritis (RA) and limited or no prior methotrexate (MTX) exposure. METHODS Data up to 24 weeks were analysed for 71 Japanese patients from a 52-week global Phase 3 study. Patients with RA and limited or no prior MTX exposure were randomised in a 2:1:1:2 ratio to filgotinib 200 mg plus MTX, filgotinib 100 mg plus MTX, filgotinib 200 mg, or MTX. Maximum MTX dose was 15 mg/week. Primary endpoint was proportion achieving 20% improvement in American College of Rheumatology criteria (ACR20) at Week 24. RESULTS Week 24 ACR20 rates in Japanese patients were 82.6%, 90.9%, 83.3%, and 80.0% for filgotinib 200 mg plus MTX, filgotinib 100 mg plus MTX, filgotinib 200 mg, and MTX, respectively. Greater ACR20 rates with filgotinib vs MTX occurred at Week 2. Greater proportions receiving filgotinib vs MTX achieved DAS28-CRP <2.6 at Weeks 12 and 24. Adverse event rates were comparable across treatments and between the Japanese and overall populations. CONCLUSIONS While Week 24 ACR20 rates were similar, filgotinib provided faster responses and higher remission rates vs MTX. In Japanese patients with RA and limited or no prior MTX exposure, filgotinib was generally well tolerated.

Abstract
Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by joint inflammation and progressive disability when inflammation cannot be sufficiently controlled. Despite treatment with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and biological DMARDs (bDMARDs), up to 30% of RA patients do not reach or fail to maintain a good response over time. The recent introduction of Janus kinase inhibitors (JAKis) has widened the rheumatologist's armamentarium. Filgotinib, a selective JAK1 inhibitor, has been approved by the European Medicines Agency (EMA) for treatment of RA. Phase II and III studies highlighted filgotinib safety and efficacy in RA patients naive to DMARDs or with inadequate response to csDMARDs and bDMARDs. Filgotinib is administered orally at 200 mg every day. For patients older than 75 years or with moderate to severe renal impairment, a dose of filgotinib 100 mg every day is recommended.

Abstract
OBJECTIVES Evaluate the efficacy and safety of the Janus kinase-1 inhibitor filgotinib in Japanese patients with rheumatoid arthritis (RA) and inadequate response to methotrexate (MTX). METHODS Data from 147 Japanese patients in FINCH 1, a 52-week global Phase 3 study, were analysed up to 24 weeks. Patients received once-daily filgotinib 200 or 100 mg, biweekly adalimumab, or placebo, all with stable background MTX. RESULTS In the Japanese population, American College of Rheumatology 20% response rates at Week 12 (primary endpoint) were 77.5%, 65.9%, 53.6%, and 36.8% for filgotinib 200 mg, filgotinib 100 mg, adalimumab, and placebo. Proportions of patients achieving Disease Activity Score with 28 joints <2.6 at Week 24: filgotinib 200 mg, 65.0%; filgotinib 100 mg, 51.2%; adalimumab, 42.9%; and placebo, 5.3%. Incidence rates of serious infections: filgotinib 200 mg, 2.5%; filgotinib 100 mg, 0%; adalimumab, 10.7%; and placebo, 5.3%. Treatment-emergent laboratory abnormalities Grade ≥3 occurred in five (12.5%) filgotinib 200 mg, three (7.3%) filgotinib 100 mg, one (3.6%) adalimumab, and no placebo patients. No deaths were reported among Japanese patients. CONCLUSIONS Filgotinib once daily combined with MTX was effective and generally safe and well tolerated up to Week 24 in Japanese patients with RA and inadequate response to MTX.

Abstract
PURPOSE OF REVIEW To discuss the potential role of JAK inhibitors (JAKis) as a new therapeutic class for the treatment of axial spondyloarthritis (axSpA, including ankylosing spondylitis [AS] and non-radiographic axSpA [nr-axSpA]). RECENT FINDINGS A phase III randomized controlled trial of tofacitinib (a "pan JAKi") in patients with active AS was found to be superior to placebo in achieving the ASAS20 primary endpoint at week 16 (56.4% and 29.4%, p < 0.0001, phase II trials of AS). Upadacitinib, a JAK1 inhibitor, has also been evaluated in a phase III trial for its efficacy and safety in AS. The primary endpoint, ASAS40 at week 16, was reached by 52% of the patients randomized to upadacitinib and 26% of the patients receiving placebo (p = 0·0003). All the important secondary endpoints also improved with both agents. No new changes in their safety profile were noted. However, the more frequent occurrence of cardiovascular and cancer adverse events associated with tofacitinib than with TNFi observed in the very recent post-marketing "ORAL surveillance" safety study, the results of which were released on January 27, 2021, may lead to safety concerns swirling around the whole class of JAKis. JAKis seem to be effective in treating signs and symptoms of AS but have not been studied in nr-axSpA. Both tofacitinib and upadacitinib have been pre-registered with the FDA for the treatment of AS. Upadacitinib has just recently received approval for this indication in the European Union..

Abstract
Background Rheumatoid arthritis (RA) is a systemic autoimmune disease. The combination therapy of methotrexate (MTX) and Janus kinase inhibitor (JAKi) is commonly used. Patients with RA are at increased risk of malignancy, however, it remains unclear whether the combination therapy is associated with a higher risk. Objective To assess the malignancy risk among patients with RA receiving combination therapy of JAKi and MTX compared to MTX alone. Methods PubMed, Cochrane and Embase were thoroughly searched for randomized controlled trials (RCTs) in patients with RA receiving JAKi and MTX, from inception to July 2020. Primary endpoints were malignancy events, Non melanomatous skin cancer (NMSC) and malignancy excluding NMSC and secondary endpoints were serious adverse events (SAE), deaths. Risk ratio (RR) and 95% CI were calculated using the Mantel–Haenszel random-effect method. Results 659 publications were screened and 13 RCTs with a total of 6911 patients were included in the analysis. There was no statistically significant difference in malignancy [RR = 1.42; 95% CI (0.59, 3.41)], neither NMSC [RR = 1.44 (0.36, 5.76)] nor malignancies excluding NMSC [RR = 1.12 (0.40, 3.13)]. No statistically significant difference between the two groups for SAE [RR = 1.15 (0.90, 1.47)] and deaths [RR = 1.99 (0.75, 5.27)] was found. Conclusion The adjunction of JAKi to MTX is not associated with an increased risk of malignancy when compared to MTX alone. There is no increased risk of SAE and deaths when compared to MTX alone in patients with RA.

Abstract
PURPOSE To investigate the protective effect of filgotinib in endotoxin-induced uveitis model in rats. MATERIALS AND METHOD This study used 24 Wistar Albino rats. Group I (control group) included the healthy controls; in Group II (sham group), only 300 µg/kg intraperitoneal (ip) lipopolysaccharide (LPS) was administered; and in Group III (treatment group), 3 mg/kg/day filgotinib was administered orally for 10 days followed by 300 µg/kg ip LPS. In all groups, clinical activity scores were evaluated after 24 h. Moreover, histopathological and immunological examinations were performed. RESULTS In Groups I, II, and III, the mean clinical activity and histopathological examination scores were 0.00, 3.25 ± 0.70, and 1.89 ± 0.60 and 0.00, 2.88 ± 1.12, and 1.44 ± 0.52, respectively. The clinical activity and histopathological examination scores were significantly increased in the sham group compared to the control group (p < 0.05); these findings were significantly reduced in the treatment group (p < 0.05). The mean TNF-α and IL-6 ELISA levels in all groups were 50.20 ± 3.24, 59.87 ± 2.98, and 54.34 ± 4.62 and 30.88 ± 1.79, 36.77 ± 1.21, and 33.66 ± 1.86, respectively. The TNF-α and IL-6 ELISA levels were significantly decreased in the treatment group compared to the sham group (p < 0.05); there was no significant difference between the treatment group and the control group (p = 0.105, p = 0.067, respectively) CONCLUSION: Filgotinib may be an alternative treatment option in preventing the development of noninfectious uveitis.

Abstract
INTRODUCTION Rheumatoid arthritis (RA) is a chronic autoimmune disease, whose natural course has been deeply modified thanks to the development of new therapeutic approaches. The Janus kinase inhibitors (Jakinibs) represent the newest class of drugs introduced for treating RA. Among these, Filgotinib (FIL) has been developed as Janus kinase1 (JAK1) selective inhibitor, specifically targeting key pro-inflammatory mediators in RA pathogenesis. AREAS COVERED This narrative review provides an overview on FIL as new therapeutic approach for RA, with focus on its pharmacological properties, clinical efficacy, and safety profile. The following electronic databases were adopted for the study search: PubMed, Google Scholar, ClinicalTrials.gov and Abstract archive from the American College of Rheumatology and the European Alliance of Associations for Rheumatology. EXPERT OPINION The phase II and phase III randomized controlled trials (RCTs) performed so far and their long-term extensions showed a comparable clinical efficacy of FIL to biologic treatments, with an acceptable safety profile. Thanks to these data, FIL was approved in Europe and Japan for the treatment of active RA, increasing the spectrum of therapeutic approaches and improving the possibility of a more tailored therapeutic strategy. Real-life data and head-to-head clinical trials will be needed to confirm its efficacy and safety.

Abstract
OBJECTIVES To evaluate efficacy and safety of filgotinib in Japanese RA patients who have failed or were intolerant to one or more biologic disease-modifying antirheumatic drugs (bDMARD) from the global FINCH 2 study (NCT02873936). METHODS This subgroup analysis was performed using the predefined statistical analyses. The FINCH 2 study is a randomized, double-blind, placebo-controlled, Phase 3 study in adult RA patients with inadequate response to bDMARDs. The randomized patients were treated with once-daily filgotinib 200 mg, filgotinib 100 mg or placebo on a background of csDMARDs for 24 weeks. RESULTS Of 449 patients enrolled in the overall population, 40 patients were enrolled from Japan. In the Japanese population, the American College of Rheumatology 20% response rates at week 12 (primary endpoint) were 83.3% and 53.3% for filgotinib, 200 mg and 100 mg, respectively, vs 30.8% for placebo. Filgotinib was well tolerated, similar to the overall population. CONCLUSIONS Both doses of once-daily filgotinib 200 mg and filgotinib 100 mg were effective, and generally well-tolerated in Japanese patients with active refractory RA.

Abstract
An assessment of the relative efficacy and tolerability of tofacitinib, baricitinib, upadacitinib, and filgotinib compared to those of methotrexate (MTX) was performed in disease-modifying antirheumatic drug (DMARD)-naive patients with rheumatoid arthritis (RA). We performed a Bayesian network meta-analysis to combine direct and indirect evidence from randomized controlled trials (RCTs) so as to examine the efficacy and safety of tofacitinib, baricitinib, upadacitinib, filgotinib, and MTX in DMARD-naïve RA patients. Four RCTs comprising 2185 patients met the inclusion criteria. The ranking probability based on the surface under the cumulative ranking curve (SUCRA) indicated that upadacitinib 15 mg had the highest probability of achieving the American College of Rheumatology 20% (ACR20) response rate, followed by baricitinib 4 mg, tofacitinib 5 mg, filgotinib 200 mg, and MTX. Tofacitinib, baricitinib, upadacitinib, and filgotinib treatments achieved significantly higher ACR50 and ACR70 responses compared to MTX. Tofacitinib 5 mg had the highest probability of achieving the ACR50 and ACR70 response rates, followed by upadacitinib 15 mg, baricitinib 4 mg, filgotinib 200 mg, and MTX. The safety analysis based on serious adverse events, adverse events (AEs), and withdrawals due to AEs revealed no statistically significant differences between the respective intervention groups. In conclusion, tofacitinib, baricitinib, upadacitinib, and filgotinib were effective treatment options for DMARD-naïve RA patients, suggesting a difference in efficacy and safety among the different JAK inhibitors.

Abstract
PURPOSE OF THE REVIEW Three Janus kinase (JAK) inhibitors are approved for rheumatoid arthritis (RA) with a fourth awaiting approval. Multiple clinical trial results with these molecules have recently been reported. These were the first small molecule oral targeted synthetic DMARDs (tsDMARDs) to be approved for RA. RECENT FINDINGS Preclinical studies have suggested differential affinity for JAK isoform inhibition but it is not presently clear that there is any difference in efficacy in the clinic with these therapies. Preliminary data has suggested that filgotinib may have a modestly different safety profile but lacking direct comparisons, this will be difficult to confirm. Long-term safety studies have suggested similar safety signals to biologics although a possible signal for VTE/PE risk has been noted with tofacitinib and baricitinib. Having an oral small molecule such as the JAK inhibitors with similar or better efficacy than biologics has been a major advance in RA treatment.

Abstract
Filgotinib is a selective JAK1 (Janus kinase) inhibitor, showed efficacy in patients suffering from moderate-to-severe rheumatoid arthritis. In this paper, we present the data on the development and validation of a sensitive, selective and high-throughput LC-MS/MS (liquid chromatography with tandem mass spectrometry) method for the quantitation of filgotinib from rat dried blood spot (DBS) cards. To the DBS disc cards, 0.2% formic acid enriched with internal standard (IS) was added and sonicated. Thereafter the extraction of filgotinib and the IS (tofacitinib) was accomplished using ethyl acetate as an extraction solvent. The resolution of filgotinib and the IS was achieved on a Gemini C18 column with an isocratic mobile phase, which is a mixture of 0.2% formic acid:acetonitrile (20:80, v/v) at a flow-rate of 0.9 mL/min. The total run time was 2.90 min and the retention time of filgotinib and the IS was ~1.31 and 0.89 min, respectively. Filgotinib and the IS were analyzed using positive ion scan mode and parent-daughter mass to charge ion (m/z) transition of 426.3→291.3 and m/z 313.2→149.2, respectively, for quantitation. The calibration range was 1.37-1937 ng/mL. No matrix effect and carry over were observed. All the validation parameters met the acceptance criteria. The validated method has been applied to a pharmacokinetic study in rats. A good correlation between DBS and plasma concentrations for filgotinib was observed.

Abstract
Janus kinase (JAK) inhibitors are novel small molecules with a mechanism of action in multiple signaling pathways that allows their application in a broad spectrum of autoimmune and autoinflammatory diseases. As far as the field of dermatology is concerned, chronic plaque psoriasis is currently one of the most studied indications regarding the potential use of JAK inhibitors. The purpose of this review is to provide a summarized overview of the existing information on the efficacy and safety of JAK inhibitors in plaque psoriasis, with a focus on tofacitinib, ruxolitinib, baricitinib, peficitinib and filgotinib. Although the published data on the therapeutic benefit of these agents in the therapy of this chronic condition are promising, further prospective studies and real-life data are necessary in order to sufficiently evaluate their role as an adequate treatment option for psoriatic patients.

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
Background The aim was to assess patient-reported outcomes (PROs) in patients with rheumatoid arthritis (RA) treated with filgotinib during two phase 2b, 24-week, randomized, placebo-controlled studies. Methods Patients with moderate-to-severe active RA and an inadequate response to methotrexate (MTX) were randomized to daily placebo or filgotinib 50 mg, 100 mg, or 200 mg as add-on therapy to MTX (NCT01888874) or as monotherapy (NCT01894516). At week 12, nonresponders receiving filgotinib 50 mg in both studies or placebo in the add-on study, and all patients receiving placebo as monotherapy, were re-assigned to filgotinib 100 mg. PROs were measured using the Health Assessment Questionnaire - Disability Index (HAQ-DI) including Patient Pain assessed by visual analog scale, and the Patient Global Assessment of Disease Activity (Patient Global), the Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue Scale (Version 4), and the 36-Item Short Form Health Survey (SF-36). Results At week 12, improvements in all PROs, apart from the SF-36 mental component in the add-on study, were statistically better with filgotinib than placebo; some improvements were noted as early as the first assessment time point (week 1 or week 4). Filgotinib improved HAQ-DI by 0.58–0.84 points, FACIT-Fatigue by 6.9–11.4 points, Patient Global by 25.2–35.6 mm, and Pain by 24.2–37.9 mm; scores were maintained or improved to week 24. Across all PROs, more patients achieved minimal clinically important differences and normative values with filgotinib 200 mg than placebo. Patients re-assigned to filgotinib 100 mg at week 12 experienced improvements in PROs between weeks 12 to 24. Conclusions Filgotinib as MTX add-on therapy or as monotherapy demonstrated rapid and sustained (to 24 weeks) improvements in health-related quality of life and functional status in patients with active RA. Trial registration MTX add-on study: ClinicalTrials.gov, NCT01888874. Registered on 28 June 2013. Monotherapy study: ClinicalTrials.gov, NCT01894516. Registered on 10 July 2013.

Abstract
There is an ongoing, unmet need for effective therapies for Crohn's disease. Treatments for Crohn's disease continue to evolve from the traditional biologics to novel small molecules, with targeted mechanisms directed toward pathways that are dysregulated in Crohn's disease. There are multiple emerging mechanisms of action, including Janus kinase inhibition, Smad7 inhibition, and sphingosine-1-phosphate receptor modulators, that are administered as oral medications, and small molecules represent the next generation of therapies for Crohn's disease.

Abstract
INTRODUCTION Biologics were the first targeted therapies for rheumatoid arthritis (RA), having in common high clinical efficacy. Being proteins, they are administered parenterally. The first oral targeted small molecules approved for RA are competitive inhibitors of the Janus kinase (JAK) enzyme family which mediate signalling for a cytokine subset important in RA pathogenesis. Areas covered: Several JAK inhibitors have been developed with differing selectivity for the four JAK enzymes with a view to generating oral, multi-cytokine inhibitors. Here we review the pharmacology and clinical trial data for efficacy and safety of filgotinib, an investigational selective JAK1 inhibitor. We contextualise the contemporary approach to RA management and substantial unmet needs that remain. Expert opinion: The selectivity of filgotinib for JAK1 may have theoretical advantages in terms of limiting toxicity. However, establishing whether this is so before larger numbers of patients are exposed in phase III and beyond in the real word setting, will be difficult. Filgotinib clinical trial data to date has been encouraging with rapid, sustained efficacy with promising safety and tolerability. We are likely to see an expanding choice of approved JAK inhibitors in the clinic but it may not be straightforward to distinguish safety and efficacy differences.

Abstract
Pfizer's Xeljanz (tofacitinib citrate) was the first Janus kinase (JAK) inhibitor to reach the market for rheumatoid arthritis (RA) following its U.S. approval in November 2012, and it has since gained approval in more than 45 countries as a second-line therapy for RA after failure of disease-modifying antirheumatic drugs (DMARDs). This emerging category has heralded an attractive new class of oral treatment options in RA, with a notable opportunity in patients who stop responding to DMARDs, but they are facing a challenging market. Despite RA affecting approximately 23.7 million people worldwide, Xeljanz faces a market dominated by the anti-tumor necrosis factor (anti-TNF) biologicals, which have robust long-term safety and efficacy. The availability of biosimilars of these market leaders is also intensifying competition, and a high price and uncertainty over long-term safety is currently tempering the market for the JAK inhibitors.
