Objective. To report 5-year efficacy and safety of upadacitinib (UPA) in rheumatoid arthritis (RA) from the phase III long-term extension (LTE) of SELECT-NEXT. Methods. Patients on stable conventional synthetic disease-modifying antirheumatic drugs were randomized to UPA 15 mg once daily (QD), UPA 30 mg QD, or placebo for 12 weeks. Following this, placebo-randomized patients were switched to UPA 15 mg QD or UPA 30 mg QD in the LTE; UPA-randomized patients continued their original dose. Blinding remained until dose switching from UPA 30 mg QD to UPA 15 mg QD because of approval of UPA 15 mg QD; the earliest switch occurred at week 168. Efficacy (as observed) and treatment-emergent adverse events (TEAEs) are reported through 5 years. Results. Overall, 611 (92%) randomized patients entered the LTE; 271 (44%) discontinued the study drug by 5 years, primarily because of adverse events (16%). Clinical outcomes improved or were maintained at 5 years; 51% and 43% of patients achieved Clinical Disease Activity Index remission and 75% and 66% achieved Disease Activity Score in 28 joints based on C-reactive protein < 2.6 among those initially randomized to UPA 15 mg QD and UPA 30 mg QD, respectively. Proportions of patients achieving ≥ 20%/50%/70% improvement in American College of Rheumatology criteria responses increased from week 60 through 5 years. Results were similar regardless of initial randomization to UPA or placebo. TEAEs, including TEAEs of special interest, were consistent with earlier analyses and other SELECT studies. Malignancies (excluding nonmelanoma skin cancer), major adverse cardiovascular events, and venous thromboembolic events were reported infrequently. No new safety signals were observed. Conclusion. The 5-year benefit-risk profile for UPA in RA remains favorable. (SELECT-NEXT; ClinicalTrials.gov: NCT02675426) [ABSTRACT FROM AUTHOR]

Introduction: This integrated analysis of the phase 2/3 and phase 3 SELECT trials describes the safety profile of upadacitinib, an oral Janus kinase inhibitor, for up to 5 years of exposure across psoriatic arthritis (PsA), ankylosing spondylitis (AS), and non-radiographic axial spondyloarthritis (nr-axSpA) (including pooled axial spondyloarthritis [axSpA]). Methods: Safety data from five trials of upadacitinib in PsA (2 trials), AS (2 trials), and nr-axSpA (1 trial) were analyzed up to a data cut-off of August 15, 2022. One PsA study included adalimumab as an active comparator. Treatment-emergent adverse events (TEAEs) were summarized for PsA (pooled upadacitinib 15 mg once daily and adalimumab 40 mg biweekly), AS (pooled upadacitinib 15 mg), nr-axSpA (upadacitinib 15 mg), and pooled axSpA (pooled upadacitinib 15 mg from axSpA trials). TEAEs were reported as exposure-adjusted event rates per 100 patient-years (E/100 PY). Results: A total of 1789 patients (PsA, n = 907; AS, n = 596; nr-axSpA, n = 286) received ≥ 1 dose of upadacitinib 15 mg for 3689 PY of exposure or adalimumab (n = 429) for 1147 PY of exposure. Overall TEAEs and serious TEAEs were highest in PsA and numerically higher with upadacitinib versus adalimumab; rates were similar between AS and nr-axSpA. In PsA, higher rates of serious infection, herpes zoster (HZ), lymphopenia, and nonmelanoma skin cancer (NMSC) were observed with upadacitinib versus adalimumab. Rates of malignancy excluding NMSC, adjudicated major adverse cardiovascular events, and adjudicated venous thromboembolic events were comparable between upadacitinib and adalimumab in PsA and were similar across diseases. Conclusion: Higher rates of serious infection, HZ, lymphopenia, and NMSC were observed with upadacitinib versus adalimumab in PsA; slightly elevated rates for most of these TEAEs were seen with upadacitinib in PsA versus axSpA. Upadacitinib 15 mg demonstrated a generally consistent safety profile across disease states with no new safety signals identified. Trial Registration: SELECT-AXIS 1: NCT03178487; SELECT-AXIS 2: NCT04169373; SELECT-PsA 1: NCT03104400; SELECT-PsA 2: NCT03104374. Plain Language Summary: Psoriatic arthritis, ankylosing spondylitis, and non-radiographic axial spondyloarthritis are a group of diseases that cause pain and inflammation of the joints and/or spine. Safety data were combined from five studies: two in psoriatic arthritis, two in ankylosing spondylitis, and one in non-radiographic axial spondyloarthritis. Patients were treated with upadacitinib or adalimumab for up to 5 years. Adalimumab was only used for patients participating in one of the two psoriatic arthritis studies. Side effects from treatment were more common in patients with psoriatic arthritis than those with ankylosing spondylitis and non-radiographic axial spondyloarthritis; more patients with psoriatic arthritis had side effects with upadacitinib than adalimumab. A similar number of patients across treatment groups and diseases had side effects that made them stop treatment. The number of cancer cases (except cancer of the upper layer of the skin), cardiovascular issues, and blood clots were similar between the upadacitinib and adalimumab groups in psoriatic arthritis and across diseases. Serious infections, painful rashes that cause blisters (herpes zoster, also commonly referred to as shingles), low levels of white blood cells, and cancer of the upper layer of the skin were more common with upadacitinib than adalimumab in patients with psoriatic arthritis; overall, these events occurred more often with upadacitinib in patients with psoriatic arthritis than with ankylosing spondylitis and non-radiographic axial spondyloarthritis. Our results showed that the safety of upadacitinib was generally similar across diseases, and patients could tolerate it well for up to 5 years. No new safety risks were found with upadacitinib treatment. [ABSTRACT FROM AUTHOR]

Introduction: Upadacitinib (UPA) is a Janus kinase inhibitor that has demonstrated efficacy in moderate-to-severe rheumatoid arthritis (RA) with an acceptable safety profile. We investigated laboratory parameter changes in UPA RA clinical trials. Methods: Pooled data from six randomized trials in the SELECT phase 3 program were included. Key laboratory parameters and safety data were measured for UPA 15 and 30 mg once daily (QD), adalimumab (ADA) 40 mg every other week + methotrexate (MTX), and MTX monotherapy. Exposure-adjusted event rates (EAERs) of adverse events were calculated. Results: A total of 3209 patients receiving UPA 15 mg QD (10 782.7 patient-years [PY]), 1204 patients receiving UPA 30 mg QD (3162.5 PY), 579 patients receiving ADA + MTX (1573.2 PY), and 314 patients receiving MTX monotherapy (865.1 PY) were included, representing up to 6.5 years of total exposure. Decreases in mean levels of hemoglobin, neutrophils, and lymphocytes, and increases in mean levels of liver enzymes and creatinine phosphokinase were observed with UPA, with grade 3 or 4 changes observed in some patients. Mean low- and high-density lipoprotein cholesterol ratios remained stable for patients receiving UPA 15 mg QD. EAERs of anemia and neutropenia occurred at generally consistent rates between UPA and active comparators (3.1–4.3 and 1.7–5.0 events [E]/100 PY across treatment groups, respectively). Rates of hepatic disorder were higher with MTX monotherapy, UPA 15 mg and UPA 30 mg (10.8, 9.7, and 11.0 E/100 PY, respectively) versus ADA + MTX (6.4 E/100 PY). Rates of lymphopenia were highest with MTX monotherapy (3.2 E/100 PY). Treatment discontinuations due to laboratory-related events were rare, occurring in 1.1% and 2.2% of patients treated with UPA 15 and 30 mg QD, respectively. Conclusions: The results of this integrated long-term analysis of laboratory parameters continue to support an acceptable safety profile of UPA 15 mg QD for moderate-to-severe RA.

Introduction: Immune-mediated inflammatory diseases including rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), non-radiographic axial spondylarthritis (nr-axSpA), atopic dermatitis (AD), ulcerative colitis (UC), and Crohn's disease (CD) pose a substantial burden on patients and their quality of life. Upadacitinib is an orally administered, selective, and reversible Janus kinase inhibitor indicated for seven conditions, but data on its safety versus other active treatments are limited. A systematic literature review of indirect and direct treatment comparisons of randomized controlled trials (RCTs) was conducted to assess the safety profile of upadacitinib. Methods: MEDLINE, Embase, and Cochrane Library databases were searched for indirect and direct treatment comparisons of RCTs that (1) included licensed upadacitinib dosages; (2) studied any of the seven conditions; (3) reported any adverse events (AEs), serious AEs (SAEs), AEs leading to discontinuation, major adverse cardiovascular event, venous thromboembolism, malignancies, infections or serious infections, and death; and (4) were published between January 2018 and August 2022. Results: A total of 25 studies were eligible for inclusion. SAEs, AEs leading to discontinuation, and any AEs were commonly studied. RA was the most studied condition, followed by AD and UC. Most studies (16/25, 64%) reported no statistically significant difference in the studied safety outcomes between upadacitinib and other active treatments (e.g., tumor necrosis factor blockers, interleukin receptor antagonists, integrin receptor antagonists, T cell co-stimulation modulator), or placebo (placebo ± methotrexate or topical corticosteroids). Other studies (9/25, 36%) reported mixed results of no statistically significant difference and either statistically higher (8/25, 32%) or lower rates (1/25, 4%) on upadacitinib. Conclusion: Most studies suggested that upadacitinib has no statistically significant difference in the studied safety outcomes compared to active treatments or placebo in patients with RA, PsA, AS, AD, UC, and CD. A few studies reported higher rates, but findings were inconsistent with limited interpretation. [ABSTRACT FROM AUTHOR]

The use of different pathways in the treatment of rheumatoid arthritis has led to a significant decrease in the number of treatment-resistant patients. In this context, interleukin (IL)-6 inhibition has filled an important gap in rheumatoid arthritis treatment with its effectiveness and safety in both monotherapy and combinations. The process of IL-6 inhibition initiated with IL-6 receptor blockers has prompted questions regarding the potential impact and safety of different inhibitions of this pathway, such as the direct blockade of IL-6. Following the termination of the development of sirukumab because of mortality data in early studies, the investigation of olokizumab, which targets a different region of the IL-6 cytokine, has renewed the hope in this area and the safety concerns have been largely alleviated by the open-label extension data. In addition, the efficacy and safety of tocilizumab and sarilumab have led to a rapid investigation of biosimilars and new potent IL-6 receptor blockers. A comprehensive understanding of mechanisms of this pathway with further long-term clinical data and basic research may provide a decisive impact on selecting the appropriate mechanism as the first choice in personalized treatments.

Introduction: RA-BE-REAL is a 3-year, multinational, prospective, observational study of adult patients with rheumatoid arthritis (RA) evaluating time to discontinuation of initial RA treatment along with patient baseline characteristics. This study's primary objective was to assess the time to discontinuation of initial baricitinib, any other targeted synthetic disease-modifying anti-rheumatic drug (tsDMARD), or any biologic disease-modifying anti-rheumatic drug (bDMARD) treatment for all causes (excluding sustained clinical response) over 24 months in a European population. Methods: Patients initiated treatment with baricitinib (cohort A) or any bDMARD or tsDMARD (cohort B) for the first time. This study's primary objective was to assess the time to discontinuation of initial baricitinib, any other targeted synthetic disease-modifying anti-rheumatic drug (tsDMARD), or any biologic disease-modifying anti-rheumatic drug (bDMARD) treatment for all causes (excluding sustained clinical response) over 24 months in a European population. Comparative effectiveness analyses, over 24 months, included time to treatment discontinuation for all causes (excluding sustained clinical response), percentage of patients achieving Clinical Disease Activity Index (CDAI) remission or low disease activity (LDA), as well as mean changes from baseline for CDAI, pain visual analogue scale, and the Health Assessment Questionnaire-Disability Index (HAQ-DI). For this European subpopulation, comparative analyses were performed using a frequentist model averaging (FMA) framework based on a data-driven machine learning causal inference approach to compare time to discontinuation, effectiveness, rates of remission or LDA, and patient-reported outcomes over 24 months comparing baricitinib with TNFi, as well as non-TNFi and tsDMARD grouped as other mechanism of action (OMA) drugs. Results: In the European sample of RA-BE-REAL, patients with RA treated with baricitinib experienced fewer discontinuations in comparison to those treated with tumour necrosis factor inhibitors or OMA. Overall, patients naïve to b/tsDMARDs achieved a higher rate of LDA and remission compared with experienced patients. A significantly greater proportion of patients treated with baricitinib achieved LDA compared with b/tsDMARDs. Conclusion: This real-world data can better inform clinicians about baricitinib effectiveness and drug survival when prescribing treatment for patients with RA across different subpopulations.

Introduction: The safety of tofacitinib in psoriatic arthritis (PsA) and rheumatoid arthritis (RA) has been demonstrated in clinical studies of ≤ 4 and 9.5 years, respectively. Post-marketing surveillance (PMS) data for tofacitinib from spontaneous and voluntary adverse event (AE) reports have been published for RA, but not PsA. To inform the real-world safety profile of tofacitinib in PsA, we evaluated AE reports submitted to the Pfizer safety database (including RA data for context). Methods: Endpoints included AEs, serious AEs (SAEs), AEs of special interest (AESIs; serious infections, herpes zoster, cardiovascular events, malignancies, venous thromboembolism), and fatal cases. Exposure was estimated using IQVIA global commercial sales data. Number, frequency, and reporting rates (RRs; number of events/100 patient-years' [PY] exposure) were summarized by indication and formulation (immediate release [IR] 5 or 10 mg twice daily], modified release [MR] 11 mg once daily, or all tofacitinib). The data-collection period differed by indication (PsA: 14 December 2017 [US approval, IR/MR] to 6 November 2021; RA: 6 November 2012 [US approval, IR] to 6 November 2021; MR approval, 24 February 2016). Results: A total of 73,525 case reports were reviewed (PsA = 5394/RA = 68,131), with 20,706/439,370 PY (PsA/RA) of exposure. More AEs were reported for IR versus MR (IR/MR: PsA = 8349/7602; RA = 137,476/82,153). RRs for AEs (IR/MR: PsA = 59.6/113.4; RA = 44.0/64.8) and SAEs (PsA = 8.1/13.6; RA = 8.0/9.5) were higher with MR versus IR. AE RRs (RA) in the first 4 years after IR approval were 95.9 (IR; 49,439 PY) and 147.0 (MR; 2000 PY). Frequency of SAEs, AESIs, and fatal cases was mostly similar across formulations and indications. The most frequently-reported AE Preferred Terms (PsA/RA) included drug ineffective (20.0%/17.8%), pain (9.7%/10.6%), condition aggravated (9.9%/10.5%), headache (8.8%/7.9%) and, for PsA, off-label use (10.5%/3.4%). Conclusions: Tofacitinib PMS safety data from submitted AE reports were consistent between PsA and RA, and aligned with its known safety profile. Exposure data (lower MR versus IR; estimation from commercial sales data), reporting bias, reporter identity, and regional differences in formulation use limit interpretation. [ABSTRACT FROM AUTHOR]

Objective To evaluate the long-term safety and efficacy of sarilumab with/without conventional synthetic (cs)DMARDs in RA. Methods The analyses evaluated two open-label extensions (OLEs): EXTEND and MONARCH OLE, which included patients from six randomized trials. Patients received sarilumab 200 mg once every 2 weeks (q2w) for at least 264 weeks up to 516 weeks (EXTEND: Sarilumab Monotherapy and Sarilumab + csDMARD groups) or for 276 weeks (MONARCH OLE: Continuation and Switch groups). Primary endpoints included safety, immunogenicity and changes in laboratory parameters. Secondary endpoints included clinical signs and symptoms along with health-related quality-of-life (HRQOL) questionnaires. Results The Sarilumab Monotherapy (n  =   111), Continuation (n  =   165) and Switch (n  =   155) groups received sarilumab monotherapy, while the Sarilumab + csDMARD group (n  =   1910) received sarilumab in combination with csDMARDs. Incidence of one or more treatment-emergent adverse events was 126 (Sarilumab Monotherapy group), 169 (Sarilumab + csDMARD group), 159 (Continuation group) and 159 (Switch group) events/100 patient-years. Neutropenia was the most common adverse event. Neutropenia was not associated with an increased incidence of infections. Most neutropenia cases normalized on-treatment. Adverse events of special interests, such as malignancies, major adverse cardiovascular events, venous thromboembolism and gastrointestinal perforations, were rare. Immunogenicity was low and not associated with hypersensitivity reactions or discontinuations due to lack or loss of efficacy. Improvements in clinical signs and symptoms and HRQOL, observed during the initial blinded trials, were maintained throughout the OLE assessment period. Conclusions Long-term sarilumab treatment with/without csDMARDs in patients with RA revealed no new safety findings. Efficacy and HRQOL were maintained or further increased over the open-label assessment period. Trial registration EXTEND, ClinicalTrials.gov, https://www.clinicaltrials.gov/ct2/show/NCT01146652 , NCT01146652; MONARCH OLE, ClinicalTrials.gov, https://clinicaltrials.gov/ct2/show/NCT02332590 , NCT02332590 [ABSTRACT FROM AUTHOR]

Objectives: Some patients with rheumatoid arthritis develop interstitial lung disease (RA-ILD) that develops into progressive pulmonary fibrosis. We assessed the efficacy and safety of nintedanib versus placebo in patients with progressive RA-ILD in the INBUILD trial. Methods: The INBUILD trial enrolled patients with fibrosing ILD (reticular abnormality with traction bronchiectasis, with or without honeycombing) on high-resolution computed tomography of >10% extent. Patients had shown progression of pulmonary fibrosis within the prior 24 months, despite management in clinical practice. Subjects were randomised to receive nintedanib or placebo. Results: In the subgroup of 89 patients with RA-ILD, the rate of decline in FVC over 52 weeks was −82.6 mL/year in the nintedanib group versus −199.3 mL/year in the placebo group (difference 116.7 mL/year [95% CI 7.4, 226.1]; nominal p = 0.037). The most frequent adverse event was diarrhoea, which was reported in 61.9% and 27.7% of patients in the nintedanib and placebo groups, respectively, over the whole trial (median exposure: 17.4 months). Adverse events led to permanent discontinuation of trial drug in 23.8% and 17.0% of subjects in the nintedanib and placebo groups, respectively. Conclusions: In the INBUILD trial, nintedanib slowed the decline in FVC in patients with progressive fibrosing RA-ILD, with adverse events that were largely manageable. The efficacy and safety of nintedanib in these patients were consistent with the overall trial population. A graphical abstract is available at: https://www.globalmedcomms.com/respiratory/INBUILD%5fRA-ILD. Key Points • In patients with rheumatoid arthritis and progressive pulmonary fibrosis, nintedanib reduced the rate of decline in forced vital capacity (mL/year) over 52 weeks by 59% compared with placebo. • The adverse event profile of nintedanib was consistent with that previously observed in patients with pulmonary fibrosis, characterised mainly by diarrhoea. • The effect of nintedanib on slowing decline in forced vital capacity, and its safety profile, appeared to be consistent between patients who were taking DMARDs and/or glucocorticoids at baseline and the overall population of patients with rheumatoid arthritis and progressive pulmonary fibrosis.

Rheumatoid arthritis (RA) synovitis is dominated by monocytes/macrophages with inflammatory patterns resembling microbial stimulation. In search of triggers, we reduced the intestinal microbiome in 20 RA patients (open label study DRKS00014097) by bowel cleansing and 7-day fasting (≤250 kcal/day) and performed immune monitoring and microbiome sequencing. Patients with metabolic syndrome (n = 10) served as a non-inflammatory control group. Scores of disease activity (DAS28/SDAI) declined within a few days and were improved in 19 of 20 RA patients after breaking the fast (median ∆DAS28 = −1.23; ∆SDAI = −43%) or even achieved remission (DAS28 < 2.6/n = 6; SDAI < 3.3/n = 3). Cytometric profiling with 46 different surface markers revealed the most pronounced phenomenon in RA to be an initially increased monocyte turnover, which improved within a few days after microbiota reduction and fasting. Serum levels of IL-6 and zonulin, an indicator of mucosal barrier disruption, decreased significantly. Endogenous cortisol levels increased during fasting but were insufficient to explain the marked improvement. Sequencing of the intestinal microbiota indicated that fasting reduced potentially arthritogenic bacteria and changed the microbial composition to species with broader metabolic capabilities. More eukaryotic, predominantly fungal colonizers were observed in RA, suggesting possible involvement. This study demonstrates a direct link between the intestinal microbiota and RA-specific inflammation that could be etiologically relevant and would support targeted nutritional interventions against gut dysbiosis as a causal therapeutic approach.

Objectives: To evaluate the long-term safety and efficacy of filgotinib (FIL) for Japanese patients with rheumatoid arthritis (RA) and limited/no prior methotrexate (MTX) exposure. We present a Japanese population subanalysis of a global randomised-controlled trial at Week 52 and interim long-term extension (LTE) to Week 48 through June 2020. Methods: Patients were randomised to FIL 200 mg plus MTX, FIL 100 mg plus MTX, FIL 200 mg, or MTX for 52 weeks. At completion, eligible patients could enrol in the LTE. Those receiving FIL continued; those receiving MTX were rerandomised (blinded) to FIL 200 or 100 mg upon discontinuation of MTX. After a 4-week washout period, MTX could be re-added. Results: Adverse event rates at Week 52 and in the LTE to Week 48 were comparable across treatment groups. Week 52 American College of Rheumatology 20% improvement (ACR20) rates were 83% (19/23), 82% (9/11), 75% (9/12), and 76% (19/25) for FIL 200 mg plus MTX, FIL 100 mg plus MTX, FIL 200 mg, and MTX, respectively. Through LTE Week 48, ACR20 rates were maintained. Conclusions: In the 56 Japanese patients treated with FIL, efficacy was maintained through Week 52 and beyond, with no increases in the incidence of adverse events. [ABSTRACT FROM AUTHOR]

Introduction: RA-BE-REAL has the overall aim of defining a profile of patients with rheumatoid arthritis (RA) starting baricitinib or any other targeted synthetic (ts) or any biologic (b) disease-modifying antirheumatic drug (DMARD) for the first time, and the primary objective of estimating time until discontinuation from any cause (excluding sustained response) of the initial treatment. Methods: RA-BE-REAL is an ongoing, prospective, observational, 36-month study in patients with RA initiating treatment with baricitinib (cohort A) or any other tsDMARD or any bDMARD (cohort B) for the first time. The primary objective is to assess the time until treatment discontinuation from any cause (excluding sustained response) at 24 months, (i.e., the rate of discontinuation of initial baricitinib or ts/bDMARD). Patient profiles of each cohort are described and compared. Post-baseline data are descriptively analyzed. This manuscript presents baseline and interim (6-month) outcomes for European patients with RA participating in the global RA-BE-REAL study. Results: Data from 1074 patients (cohort A: 509; cohort B: 565) were analyzed. For cohorts A and B, respectively, the 6-month cumulative incidence (95% confidence interval) of treatment discontinuation was 16.5 (12.9–21.1) and 23.3 (19.1–28.2), and the proportions of patients achieving remission were 25.6% and 18.5%. At baseline, mean patient age was 59.1 and 57.0 years (p = 0.010) and mean disease duration was 10.0 and 8.9 years (p = 0.047), respectively. The proportions of patients exposed to ts/bDMARDs at any time before study entry were 51.9% and 39.1%, and the proportions of patients initiated on monotherapy were 50.9% and 31.2%, respectively. Conclusion: In real-world settings, patients with RA initiating treatment with baricitinib were older and had longer disease duration than those initiating treatment with any other tsDMARD or any bDMARD. Initial descriptive data regarding treatment discontinuation (including reasons for discontinuation), effectiveness, and treatment patterns will be enriched as the study progresses.

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 FROM AUTHOR]

Objectives: To provide an update of the EULAR rheumatoid arthritis (RA) management recommendations addressing the most recent developments in the field.Methods: An international task force was formed and solicited three systematic literature research activities on safety and efficacy of disease-modifying antirheumatic drugs (DMARDs) and glucocorticoids (GCs). The new evidence was discussed in light of the last update from 2019. A predefined voting process was applied to each overarching principle and recommendation. Levels of evidence and strengths of recommendation were assigned to and participants finally voted on the level of agreement with each item.Results: The task force agreed on 5 overarching principles and 11 recommendations concerning use of conventional synthetic (cs) DMARDs (methotrexate (MTX), leflunomide, sulfasalazine); GCs; biological (b) DMARDs (tumour necrosis factor inhibitors (adalimumab, certolizumab pegol, etanercept, golimumab, infliximab including biosimilars), abatacept, rituximab, tocilizumab, sarilumab and targeted synthetic (ts) DMARDs, namely the Janus kinase inhibitors tofacitinib, baricitinib, filgotinib, upadacitinib. Guidance on monotherapy, combination therapy, treatment strategies (treat-to-target) and tapering in sustained clinical remission is provided. Safety aspects, including risk of major cardiovascular events (MACEs) and malignancies, costs and sequencing of b/tsDMARDs were all considered. Initially, MTX plus GCs is recommended and on insufficient response to this therapy within 3-6 months, treatment should be based on stratification according to risk factors; With poor prognostic factors (presence of autoantibodies, high disease activity, early erosions or failure of two csDMARDs), any bDMARD should be added to the csDMARD; after careful consideration of risks of MACEs, malignancies and/or thromboembolic events tsDMARDs may also be considered in this phase. If the first bDMARD (or tsDMARD) fails, any other bDMARD (from another or the same class) or tsDMARD (considering risks) is recommended. With sustained remission, DMARDs may be tapered but should not be stopped. Levels of evidence and levels of agreement were high for most recommendations.Conclusions: These updated EULAR recommendations provide consensus on RA management including safety, effectiveness and cost.

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 FROM AUTHOR]

Background: The optimal dose of rituximab in combination with leflunomide in patients with rheumatoid arthritis (RA) is not known. Methods: In Part 1 (previously reported) of the investigator-initiated AMARA study (EudraCT 2009-015950-39; ClinicalTrials.gov NCT01244958), improvements at week (W)24 were observed in patients randomized to rituximab + leflunomide compared with placebo + leflunomide. In the study reported here (Part 2), Part 1 responders received rituximab 500 or 1000 mg at W24/26 plus ongoing leflunomide. Patients were randomized at baseline to their eventual W24 treatment group. The Part 2 primary outcome was the mean Disease Activity Score-28 joints (DAS28) at W52, based on the last observation carried forward (LOCF) analyses and a two-sided analysis of variance. Patient-reported outcomes (PROs) and adverse events were evaluated. Results: Eighty-three patients received rituximab at W24/26 (31 rituximab→rituximab 1000 mg; 29 rituximab→rituximab 500 mg; 10 placebo→rituximab 1000 mg; 13 placebo→rituximab 500 mg). At W52, there were no significant differences in DAS28 between rituximab doses in patients originally treated with rituximab or those originally treated with placebo. In the Part 1 placebo group, the higher rituximab dose was associated with greater improvements in ACR response rates and some PROs. Adverse events were similar regardless of rituximab dose. Conclusions: Retreatment with rituximab 500 mg and 1000 mg showed comparable efficacy, whereas an initial dose of rituximab 500 mg was associated with lower response rates versus 1000 mg. Reduced treatment response with the lower dose in patients initially treated with placebo may have been influenced by small numbers and baseline disease activity. [ABSTRACT FROM AUTHOR]

Objectives: The Simplified Disease Activity Index (SDAI) is a recommended composite score for assessing the remission status in patients with rheumatoid arthritis (RA). However, determination of C-reactive protein (CRP) levels takes several hours and sometimes days and limits the use of the SDAI in the clinical setting. The aim of this study was to validate the SDAI using a quick quantitative C-reactive protein (qCRP) assay (as SDAI-Q) in RA patients. Design: This is a multicenter, prospective, cross-sectional pilot study in RA patients. Methods: Adult patients (⩾18 years) with a clinical diagnosis of RA were recruited between January 2020 and September 2020 from five rheumatologic centers located in Berlin, Germany. SDAI, SDAI-Q, Clinical Disease Activity Index (CDAI), and DAS28 scores comprising CRP, qCRP, or erythrocyte sedimentation rate (ESR) were calculated. The agreement of disease activity categories was analyzed using cross tabulations and weighted Cohen's kappa. The agreement of numerical values was analyzed with Bland–Altman plots and intraclass correlation coefficients (ICCs). Results: Overall, 100 RA patients were included in the statistical analysis. The mean value of qCRP (7.89 ± 16.98 mg/l) was slightly higher than that of routine laboratory CRP (6.97 ± 15.02 mg/l). Comparing SDAI and SDAI-Q, all patients were assigned to identical disease activity categories. Agreement of disease activity categories by CDAI and SDAI/SDAI-Q was observed in 93% with a weighted Cohen's kappa of 0.929 (95% confidence interval (CI) = 0.878; 0.981). Conclusion: The SDAI-Q showed an absolute agreement regarding the assignment of disease activity categories in comparison with the conventional SDAI. Therefore, the SDAI-Q may facilitate the application of a treat-to-target concept in clinical trials and clinical routine as a quickly available disease activity score incorporating CRP as an objective parameter.

SSc is a chronic autoimmune rheumatic disease that involves numerous organs and presents major management challenges. The histopathologic hallmarks of SSc include vasculopathy, fibrosis and autoimmune phenomena involving both innate and adaptive immune systems. Purinergic signalling is a pathway that may be implicated in the pathophysiology of several of these disease manifestations. Extracellular purines are potent signalling mediators, which have been shown to be dysregulated in SSc. As examples, purines can exacerbate vasculopathy and provoke platelet dysfunction; as well as contributing to immune dysregulation. Elements of purinergic signalling further promote organ and tissue fibrosis in several disease models. Here, we provide an overview of extracellular purine metabolism in purinergic signalling and link disorders of these to the molecular pathology of SSc. We also discuss targeting the purinergic signalling and explore the translational applications for new therapeutic options in SSc. [ABSTRACT FROM AUTHOR]

Introduction: Inflammation is a major pathological feature of pulmonary arterial hypertension (PAH), particularly in the context of inflammatory conditions such as systemic sclerosis (SSc). The endothelin system and anti-endothelin A receptor (ETA) autoantibodies have been implicated in the pathogenesis of PAH, and endothelin receptor antagonists are routinely used treatments for PAH. However, immunological functions of the endothelin B receptor (ETB) remain obscure. Methods: Serum levels of anti-ETB receptor autoantibodies were quantified in healthy donors and SSc patients with or without PAH. Age-dependent effects of overexpression of prepro-endothelin-1 or ETB deficiency on pulmonary inflammation and the cardiovascular system were studied in mice. Rescued ETB-deficient mice (ETB-/-) were used to prevent congenital Hirschsprung disease. The effects of pulmonary T-helper type 2 (Th2) inflammation on PAH-associated pathologies were analyzed in ETB-/- mice. Pulmonary vascular hemodynamics were investigated in isolated perfused mouse lungs. Hearts were assessed for right ventricular hypertrophy. Pulmonary inflammation and collagen deposition were assessed via lung microscopy and bronchoalveolar lavage fluid analyses. Results: Anti-ETB autoantibody levels were elevated in patients with PAH secondary to SSc. Both overexpression of prepro-endothelin-1 and rescued ETB deficiency led to pulmonary hypertension, pulmonary vascular hyperresponsiveness, and right ventricular hypertrophy with accompanying lymphocytic alveolitis. Marked perivascular lymphocytic infiltrates were exclusively found in ETB-/- mice. Following induction of pulmonary Th2 inflammation, PAH-associated pathologies and perivascular collagen deposition were aggravated in ETB-/- mice. Conclusion: This study provides evidence for an anti-inflammatory role of ETB. ETB seems to have protective effects on Th2-evoked pathologies of the cardiovascular system. Anti-ETB autoantibodies may modulate ETB-mediated immune homeostasis. [ABSTRACT FROM AUTHOR]

Objective: Patients with autoimmune inflammatory rheumatic diseases receiving rituximab (RTX) therapy are at higher risk of poor COVID‐19 outcomes and show substantially impaired humoral immune response to anti–SARS–CoV‐2 vaccine. However, the complex relationship between antigen‐specific B cells and T cells and the level of B cell repopulation necessary to achieve anti‐vaccine responses remain largely unknown. Methods: Antibody responses to SARS–CoV‐2 vaccines and induction of antigen‐specific B and CD4/CD8 T cell subsets were studied in 19 patients with rheumatoid arthritis (RA) or antineutrophil cytoplasmic antibody–associated vasculitis receiving RTX, 12 patients with RA receiving other therapies, and 30 healthy controls after SARS–CoV‐2 vaccination with either messenger RNA or vector‐based vaccines. Results: A minimum of 10 B cells per microliter (0.4% of lymphocytes) in the peripheral circulation appeared to be required for RTX‐treated patients to mount seroconversion to anti‐S1 IgG upon SARS–CoV‐2 vaccination. RTX‐treated patients who lacked IgG seroconversion showed reduced receptor‐binding domain–positive B cells (P = 0.0005), a lower frequency of Tfh‐like cells (P = 0.0481), as well as fewer activated CD4 (P = 0.0036) and CD8 T cells (P = 0.0308) compared to RTX‐treated patients who achieved IgG seroconversion. Functionally relevant B cell depletion resulted in impaired interferon‐γ secretion by spike‐specific CD4 T cells (P = 0.0112, r = 0.5342). In contrast, antigen‐specific CD8 T cells were reduced in both RA patients and RTX‐treated patients, independently of IgG formation. Conclusion: In RTX‐treated patients, a minimum of 10 B cells per microliter in the peripheral circulation is a candidate biomarker for a high likelihood of an appropriate cellular and humoral response after SARS–CoV‐2 vaccination. Mechanistically, the data emphasize the crucial role of costimulatory B cell functions for the proper induction of CD4 responses propagating vaccine‐specific B cell and plasma cell differentiation.

Objective Sarilumab, as monotherapy or in combination with conventional synthetic DMARDs, such as MTX, has demonstrated improvement in clinical outcomes in patients with RA. The primary objective of this post hoc analysis was to compare the efficacy of sarilumab (200 mg every 2 weeks) monotherapy (MONARCH study) with that of sarilumab and MTX combination therapy (MOBILITY study) at week 24. Methods The endpoints assessed were mean change from baseline in the Clinical Disease Activity Index (CDAI), 28-joint Disease Activity using CRP (DAS28-CRP), CRP, haemoglobin (Hb), pain visual analogue scale (VAS) and Functional Assessment of Chronic Illness Therapy (FACIT)–Fatigue. Least square (LS) mean change from baseline (95% CI) at week 24 for all endpoints was compared between the treatment arms for adjusted comparisons. Results This analysis included 184 patients on sarilumab monotherapy and 399 patients on sarilumab plus MTX. Differences (P  < 0.05) were observed in ethnicity, region, body mass index group, rheumatoid factor, anti-cyclic citrullinated peptide antibodies, swollen joint count, CRP, CDAI and oral glucocorticoid use between these treatment groups. After adjusting for these differences in a mixed-effect model repeated measure, LS mean change from baseline for all assessments was similar between the treatment groups with overlapping CIs: CDAI, −28.79 vs −26.21; DAS28-CRP, −2.95 vs −2.81; CRP, −18.31 vs −16.46; Hb, 6.59 vs 8.09; Pain VAS, −33.62 vs −31.66; FACIT-Fatigue, 9.90 vs 10.24. Conclusion This analysis demonstrated that the efficacy of sarilumab monotherapy was similar to that of sarilumab and MTX combination therapy. [ABSTRACT FROM AUTHOR]

Introduction: This integrated analysis describes the safety profile of upadacitinib, an oral Janus kinase inhibitor, at 15 and 30 mg once daily for up to 3 years of exposure in patients with active psoriatic arthritis (PsA) who had a prior inadequate response or intolerance to ≥ 1 non-biologic or biologic disease-modifying antirheumatic drug. Methods: Safety data were pooled and analyzed from two randomized, placebo-controlled phase 3 trials. Both trials evaluated upadacitinib 15 mg and 30 mg once daily, and one trial also evaluated adalimumab 40 mg every other week. Treatment-emergent adverse events (TEAEs) and laboratory data were summarized for four groups: pooled placebo, pooled upadacitinib 15 mg, pooled upadacitinib 30 mg, and adalimumab. TEAEs were reported as exposure-adjusted event rates (events per 100 patient-years [E/100 PY]) up to a data cut-off of June 29, 2020. Results: A total of 2257 patients received ≥ 1 dose of upadacitinib 15 mg (N = 907) or 30 mg (N = 921) for 2504.6 PY of exposure or adalimumab (N = 429) for 549.7 PY of exposure. Upper respiratory tract infection, nasopharyngitis, and increased creatine phosphokinase (CPK) were the most common TEAEs with upadacitinib. Rates of malignancies, adjudicated major adverse cardiovascular events (MACEs) and venous thromboembolic events (VTEs), and deaths were similar across treatment groups. Rates of herpes zoster (HZ) and opportunistic infections (OI; excluding tuberculosis, HZ, and oral candidiasis) were higher with upadacitinib versus adalimumab. Serious infection, anemia, and CPK elevations were most frequent with upadacitinib 30 mg. Potentially clinically significant laboratory abnormalities were uncommon. Conclusions: Upadacitinib 15 mg and adalimumab had similar safety profiles with the exception of HZ and OIs, consistent with what was observed in rheumatoid arthritis. Rates of malignancies, MACEs, VTEs, and deaths were comparable among patients receiving upadacitinib and adalimumab. No new safety risks emerged with longer-term exposure to upadacitinib. Trial Registration Numbers: SELECT-PsA 1: NCT03104400; SELECT-PsA 2: NCT03104374. Plain Language Summary: Psoriatic arthritis is a disease that causes inflammation of the skin and joints. Upadacitinib and adalimumab are medicines that can be used to treat this condition. This analysis combined safety data from two studies of adults with psoriatic arthritis who took upadacitinib, adalimumab, or placebo (no medicine) for up to 3 years. The most common side effects of treatment with upadacitinib were infection and inflammation of the nose and throat and higher amounts of a protein in the blood called creatinine phosphokinase. The total number of cancer cases, heart (cardiovascular) problems, blood clots (embolisms), and deaths were similar across treatment groups, including the placebo (no medicine) group. However, more patients who took upadacitinib than adalimumab or placebo (no medicine) had a painful rash that causes blisters known as herpes zoster (shingles) and infections usually seen in people with a weakened immune system. Most patients had normal blood test results and continued their treatment. Overall, upadacitinib was well tolerated for up to 3 years in patients with psoriatic arthritis. These results agree with what has been found in studies of upadacitinib in patients with rheumatoid arthritis. Safety data of upadacitinib use over a longer time will be reported later.

Objective: To report long-term safety from the completed extension trial of baricitinib, an oral selective Janus kinase inhibitor, in patients with active rheumatoid arthritis (RA).Methods: Treatment-emergent adverse events are summarised from an integrated database (9 phase III/II/Ib and 1 long-term extension) of patients who received any baricitinib dose (All-bari-RA). Standardised incidence ratio (SIR) for malignancy (excluding non-melanoma skin cancer (NMSC)) and standardised mortality ratio (SMR) were estimated. Additional analysis was done in a subset of patients who had ever taken 2 mg or 4 mg baricitinib.Results: 3770 patients received baricitinib (14 744 patient-years of exposure (PYE)). All-bari-RA incidence rates (IRs) per 100 patient-years at risk were 2.6, 3.0 and 0.5 for serious infections, herpes zoster and major adverse cardiovascular events (MACE), respectively. In patients aged ≥50 with ≥1 cardiovascular risk factor, the IR for MACE was 0.77 (95% CI 0.56 to 1.04). The IR for malignancy (excluding NMSC) during the first 48 weeks was 0.6 and remained stable thereafter (IR 1.0). The SIR for malignancies excluding NMSC was 1.07 (95% CI 0.90 to 1.26) and the SMR was 0.74 (95% CI 0.59 to 0.92). All-bari-RA IRs for deep vein thrombosis (DVT)/pulmonary embolism (PE), DVT and PE were 0.5 (95% CI 0.38 to 0.61), 0.4 (95% CI 0.26 to 0.45) and 0.3 (95% CI 0.18 to 0.35), respectively. No clear dose differences were noted for exposure-adjusted IRs (per 100 PYE) for deaths, serious infections, DVT/PE and MACE.Conclusions: In this integrated analysis including long-term data of baricitinib from 3770 patients (median 4.6 years, up to 9.3 years) with active RA, baricitinib maintained a similar safety profile to earlier analyses. No new safety signals were identified.Trial Registration Number: NCT01185353, NCT00902486, NCT01469013, NCT01710358, NCT02265705, NCT01721044, NCT01721057, NCT01711359 and NCT01885078.

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 24weeks 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 15mg/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 AC R20 rates with filgoti nib 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 FROM AUTHOR]

Despite all improvements in rheumatoid arthritis, we are still not able to prevent or cure the disease. Diagnostic delays due to lack of access to a specialist and costly therapies are still a major obstacle for many patients. Even in first-world countries, the treat-to-target principle and the goal of disease remission are often missed. Thus, rheumatoid arthritis (RA) is still the reason for disability and reduced quality of life for many patients. So, is it time to move the goalpost even further? Where are we heading next? And will we finally be able to cure the disease? These questions are addressed in our review article. [ABSTRACT FROM AUTHOR]

Objective: To characterise safety of the Janus kinase-1 preferential inhibitor filgotinib in patients with moderately to severely active rheumatoid arthritis.Methods: Data were integrated from seven trials (NCT01668641, NCT01894516, NCT02889796, NCT02873936, NCT02886728, NCT02065700, NCT03025308). Results are from placebo (PBO)-controlled (through week (W)12) and long-term, as-treated (all available data for patients receiving ≥1 dose filgotinib 200 (FIL200) or 100 mg (FIL100) daily) datasets. We calculated exposure-adjusted incidence rates (EAIRs)/100 patient-years filgotinib exposure (100PYE) for treatment-emergent adverse events (TEAEs).Results: 3691 patients received filgotinib for 6080.7 PYE (median 1.6, maximum 5.6 years). During the PBO-controlled period, TEAEs, including those of grade ≥3, occurred at comparable rates with filgotinib or PBO; long-term EAIRs of TEAEs grade ≥3 were 6.4 and 7.6/100PYE for FIL200 and FIL100. EAIRs for deaths were 0.6/100PYE for FIL200, FIL100 and PBO; long-term EAIRs were 0.5 and 0.3/100PYE for FIL200 and FIL100. EAIRs for serious infection were 3.9, 3.3 and 2.4/100PYE for FIL200, FIL100 and PBO; long-term EAIRs were 1.6 and 3.1/100PYE for FIL200 and FIL100. EAIRs for herpes zoster were 0.6, 1.1, and 1.1/100PYE for FIL200, FIL100 and PBO; long-term EAIRs were 1.8 and 1.1/100PYE for FIL200 and FIL100. EAIRs for major adverse cardiovascular events were 0, 1.7 and 1.1/100PYE for FIL200, FIL100 and PBO; long-term EAIRs were 0.4 and 0.6/100PYE for FIL200 and FIL100. No venous thromboembolism occurred during the PBO-controlled period; long-term EAIRs were 0.2 and 0/100PYE for FIL200 and FIL100.Conclusions: Over a median of 1.6 and maximum of 5.6 years of exposure, safety/tolerability of FIL200 and FIL100 were similar, with a lower incidence of infections with FIL200 among the long-term, as-treated dataset.

Introduction: Risk of herpes zoster (HZ) is increased with Janus kinase inhibitor use. We evaluated clinical study data relating to HZ management in patients with rheumatoid arthritis (RA) or psoriatic arthritis (PsA) receiving tofacitinib. Methods: This post hoc analysis included data from 21 RA and 3 PsA clinical studies; data were pooled for tofacitinib doses. Outcomes of HZ events (serious and non-serious) and tofacitinib treatment changes were evaluated in response to first and second HZ events. Median time to resolution was stratified by dermatomal involvement, history of HZ prior to tofacitinib, changes to tofacitinib treatment, anti-viral and corticosteroid use, and tofacitinib dose. Results: Seven hundred eighty-three (11.1%, N = 7061) patients with RA experienced ≥ 1 HZ event, 63 (8.0%) of whom had ≥ 2 HZ events. In patients with PsA, 36 (4.6%, N = 783) experienced ≥ 1 HZ event, 1 (2.8%) of whom had ≥ 2 HZ events. For most HZ events, tofacitinib treatment was unchanged or temporarily discontinued. The majority of patients received anti-viral treatment, most within 3 days of onset. Post-herpetic neuralgia developed in 6.9% and 3.2% of patients with RA with first and second events, respectively, and in 2.8% of patients with PsA with a first event. Most first and second events resolved (RA: 97.6% and 96.8%, respectively; PsA: 94.4% and 100%, respectively). Median time to resolution was 22.0 days for first and 15.0 days for second events for RA and 20.5 days for first and 11.0 days for second events (n = 1) for PsA. Time to resolution of first events for RA and PsA was generally numerically shorter for patients with single dermatomal HZ, history of HZ, or anti-viral use versus those without. Conclusion: Among patients receiving tofacitinib, recurrent events were more common in patients with RA versus PsA; HZ duration was shorter for repeat events. Trial Registration: NCT01262118, NCT01484561, NCT00147498, NCT00413660, NCT00550446, NCT00603512, NCT00687193, NCT01164579, NCT00976599, NCT01059864, NCT01359150, NCT02147587, NCT00960440, NCT00847613, NCT00814307, NCT00856544, NCT00853385, NCT01039688, NCT02187055, NCT00413699, NCT00661661, NCT01877668, NCT01882439, NCT01976364. Plain Language Summary: Patients with rheumatoid arthritis (RA) or psoriatic arthritis (PsA) have weakened immune responses and are more likely to get herpes zoster (HZ; also known as shingles) infections compared with the general population. Patients who receive treatments for RA or PsA that have an effect on their immune system are more likely to get HZ. Here, we assessed how common HZ was in patients with RA or PsA who were given tofacitinib during clinical trials, the management of these infections, and how this affected the course of the infection. Approximately 1 in 10 patients with RA and 1 in 20 patients with PsA had HZ. Of those patients who had HZ, 1 in 12 with RA and 1 in 36 with PsA were infected again at a later point. A small number of patients also had long-lasting pain after HZ infection. When patients had a HZ infection, most either continued treatment with tofacitinib or paused treatment for a period of time. Pausing or continuing treatment did not appear to affect how long the infection lasted or whether patients had another infection. Most patients received treatment for HZ infection, and patients who were treated had shorter infections. In most patients, infections cleared up and were more likely to clear up more quickly when patients had HZ previously. [ABSTRACT FROM AUTHOR]

Objective The objective of this study was to evaluate the long-term safety and efficacy of sarilumab over 5 years in patients with RA refractory to TNF inhibitors (TNFis). Methods Patients in the 24-week randomized controlled trial (RCT) TARGET (NCT01709578) who received double-blind placebo or sarilumab 150 or 200 mg every 2 weeks (q2w), plus conventional synthetic DMARDs (csDMARDs), were eligible to receive open-label sarilumab 200 mg q2w plus csDMARDs in the open-label extension (OLE), EXTEND (NCT01146652). OLE dose reduction to 150 mg q2w was permitted per investigators' judgement or protocol-mandated safety concerns. Safety and efficacy were assessed through treatment-emergent adverse events (AEs), laboratory abnormalities and clinical DASs. All statistics are descriptive. Results Of 546 patients, 454 (83%) were treated with sarilumab in the OLE. The cumulative observation period was 1654.8 patient-years (PY; n  =   521); 268 patients (51%) had ≥4 years' exposure. Incidence rates per 100 PY of AEs, and AEs leading to discontinuation, infection and serious infection were 160.4, 8.1, 57.8 and 3.9, respectively. Neutropenia was the most common AE (15.3 per 100 PY). An absolute neutrophil count of <1000 cells/mm3 (Grade 3/4 neutropenia) was observed in 74 patients (14.2%) and normalized on treatment in 48. Clinical efficacy was sustained through 5 years' follow-up. Efficacy was similar for patients with 1 and >1 TNFi failure, and similar for patients who either remained on 200 mg or reduced to 150 mg. Conclusion In patients with RA refractory to TNFi, sarilumab's long-term term safety profile was consistent with previous clinical studies and post-marketing reports. Efficacy was sustained over 5 years.

Objective To investigate the efficacy and safety of rituximab + LEF in patients with RA. Methods In this investigator-initiated, randomized, double-blind, placebo-controlled phase 3 trial, patients with an inadequate response to LEF who had failed one or more DMARD were randomly assigned 2:1 to i.v. rituximab 1000 mg or placebo on day 1 and 15 plus ongoing oral LEF. The primary efficacy outcome was the difference between ≥50% improvement in ACR criteria (ACR50 response) rates at week 24 (P  ≤ 0.025). Secondary endpoints included ACR20/70 responses, ACR50 responses at earlier timepoints and adverse event (AE) rates. The planned sample size was not achieved due to events beyond the investigators' control. Results Between 13 August 2010 and 28 January 2015, 140 patients received rituximab (n  = 93) or placebo (n  = 47) plus ongoing LEF. Rituximab + LEF resulted in an increase in the ACR50 response rate that was significant at week 16 (32 vs 15%; P  = 0.020), but not week 24 (27 vs 15%; P  = 0.081), the primary endpoint. Significant differences favouring the rituximab + LEF arm were observed in some secondary endpoints, including ACR20 rates from weeks 12 to 24. The rituximab and placebo arms had similar AE rates (71 vs 70%), but the rituximab arm had a higher rate of serious AEs (SAEs 20 vs 2%), primarily infections and musculoskeletal disorders. Conclusion The primary endpoint was not reached, but rituximab + LEF demonstrated clinical benefits vs LEF in secondary endpoints. Although generally well tolerated, the combination was associated with additional SAEs and requires monitoring. Trial registration EudraCT: 2009-015950-39; ClinicalTrials.gov: NCT01244958.
