Prevention of Radiographic Progression in Higher-Risk Patients with Rheumatoid Arthritis Using Filgotinib in Phase III Studies: Narrative Review of Post Hoc Analyses. Rheumatol Ther 2023; 10:1399-1415. [PMID: 37668865 PMCID: PMC10654325 DOI: 10.1007/s40744-023-00590-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Accepted: 08/01/2023] [Indexed: 09/06/2023] Open
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.

Generation-Dependent Retention Rates and Reasons for Discontinuation of Molecular Targeted Therapies in Patients with Rheumatoid Arthritis: From FIRST Registry. Rheumatol Ther 2023; 10:1705-1723. [PMID: 37856034 PMCID: PMC10654306 DOI: 10.1007/s40744-023-00603-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Accepted: 09/22/2023] [Indexed: 10/20/2023] Open
Abstract
INTRODUCTION The study aimed to optimize medical care for elderly patients with rheumatoid arthritis (RA) by examining the 3-year continuation rate of different molecular targeted therapies across age groups in Japan, which has a significant elderly population. METHODS The study included patients with RA who started molecular targeted therapies between 2013 and 2019 and divided them into three age groups. The primary outcome was to assess the 3-year continuation rate of each drug and analyze reasons for treatment discontinuation using inverse probability of treatment weighting. RESULTS Among 2292 patients analyzed, tumor necrosis factor (TNF) inhibitors were most commonly used in those younger than 65 years of age (43.5%), while Janus kinase (JAK) inhibitors were also utilized (17.1%). In contrast, JAK inhibitors were less frequently used in patients aged 75 years and older (7.8%), with cytotoxic T lymphocyte antigen 4 immunoglobulin fusion proteins (CTLA4-Ig) being the most common (39.2%). JAK inhibitors and anti-interleukin-6 receptor (IL-6R) antibodies had higher continuation rates than other drugs in patients under 65 years (p < 0.001). For those aged 65-74 years, JAK inhibitors and CTLA4-Ig had higher continuation rates (p < 0.001), while among those aged 75 years and older, CTLA4-Ig and IL-6R antibodies had higher continuation rates (p < 0.001). Inadequate efficacy was the main reason for discontinuation in all age groups, while infection leading to discontinuation increased with age. CONCLUSIONS The study highlights the need to consider different age groups separately in elderly RA care. Among patients aged 75 years and older, abatacept and anti-IL-6R antibodies showed the highest continuation rates, suggesting their potential suitability and efficacy for this specific age cohort.

Abstract
OBJECTIVE Recent advances in single-cell RNA sequencing technology have improved our understanding of the immunological landscape of rheumatoid arthritis (RA). We aimed to stratify the synovium from East Asian patients with RA by immune cell compositions and gain insight into the inflammatory drivers of each synovial phenotype. METHODS Synovial tissues were obtained from East Asian patients in Japan with RA (n = 41) undergoing articular surgery. The cellular composition was quantified by a deconvolution approach using a public single-cell-based reference. Inflammatory pathway activity was calculated by gene set variation analysis, and chromatin accessibility was evaluated using assay of transposase accessible chromatin-sequencing. RESULTS We stratified RA synovium into three distinct subtypes based on the hierarchical clustering of cellular composition data. One subtype was characterized by abundant HLA-DRAhigh synovial fibroblasts, autoimmune-associated B cells, GZMK+ GZMB+ CD8+ T cells, interleukin (IL)1-β+ monocytes, and plasmablasts. In addition, tumor necrosis factor (TNF)-α, interferons (IFNs), and IL-6 signaling were highly activated in this subtype, and the expression of various chemokines was significantly enhanced. Moreover, we found an open chromatin region overlapping with RA risk locus rs9405192 near the IRF4 gene, suggesting the genetic background influences the development of this inflammatory synovial state. The other two subtypes were characterized by increased IFNs and IL-6 signaling, and expression of molecules associated with degeneration, respectively. CONCLUSION This study adds insights into the synovial heterogeneity in East Asian patients and shows a promising link with predominant inflammatory signals. Evaluating the site of inflammation has the potential to lead to appropriate drug selection that matches the individual pathology.

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
INTRODUCTION Immunoglobulin G4-related disease (IgG4-RD) is a debilitating multiorgan disease characterized by recurring flares leading to organ dysfunction, decreased quality of life, and mortality. Glucocorticoids, the standard of care for IgG4-RD, are associated with substantial treatment-related toxicity. Inebilizumab, an antibody directed against CD19, mediates the rapid and durable depletion of CD19+ B cells thought to be involved in IgG4-RD pathogenesis. We describe the first international, prospective, double-blind, placebo-controlled trial to evaluate the safety and efficacy of B-cell depletion for flare prevention in IgG4-RD (MITIGATE). METHODS The study was designed by an international panel of physicians with expertise in IgG4-RD. Critical trial design decisions included the selection of participants, definition of clinically meaningful primary and secondary endpoints, accommodation of standard of care, and development of flare diagnostic criteria. The study is approved for conduct in 22 countries. PLANNED OUTCOMES The primary efficacy endpoint is time from randomization to the occurrence of the first centrally adjudicated and investigator-treated disease flare during the 1-year randomized controlled period. A set of novel, organ-specific flare diagnostic criteria were developed specifically for this trial, incorporating symptoms and signs, laboratory findings, imaging study results, and pathology data. MITIGATE aims to accrue 39 flares for the primary endpoint, which provides sufficient power to detect a relative risk reduction of 65% in the inebilizumab group. It is anticipated that enrollment of 160 participants will achieve this goal. Additional endpoints include safety, annualized flare rate, flare-free complete remission, quality-of-life measures, and cumulative glucocorticoid use. MITIGATE represents the first randomized, double-blind, placebo-controlled trial of any treatment strategy conducted in IgG4-RD. Data from this study will provide insights into the natural history and pathophysiology of IgG4-RD and the efficacy and safety of B-cell depletion as a therapeutic avenue. TRIAL REGISTRATION NCT04540497.

Abstract
BACKGROUND Data on belimumab efficacy in patients with lupus nephritis (LN) according to diagnosis duration or induction therapy are limited. Post hoc analyses of the phase 3, randomized, double-blind BLISS-LN study (GSK BEL114054; NCT01639339) were performed to assess belimumab efficacy on kidney-related outcomes in newly diagnosed and relapsed LN subgroups and according to the use of glucocorticoid (GC) pulses at induction. METHODS BLISS-LN randomized 448 patients with active LN to monthly intravenous belimumab 10 mg/kg or placebo plus standard therapy. Post hoc analyses assessed primary efficacy renal response (PERR) and complete renal response (CRR) at week 104, time to kidney-related event or death and time to first LN flare from week 24 in newly diagnosed and relapsed patients and patients with/without GC pulses at induction. RESULTS A greater proportion of patients achieved a PERR with belimumab versus placebo in the newly diagnosed {69/148 [46.6%] versus 55/148 [37.2%]; odds ratio [OR] 1.36 [95% confidence interval (CI) 0.85-2.20]} and relapsed [27/75 (36.0%) versus 17/75 (22.7%); OR 2.31 (95% CI 1.07-5.01)] subgroups. Similarly for CRR [newly diagnosed: 50/148 (33.8%) versus 36/148 (24.3%); OR 1.49 (95% CI 0.88-2.51) and relapsed: 17/75 (22.7%) versus 8/75 (10.7%); OR 3.11 (95% CI 1.16-8.31)]. The probability of kidney-related event or death, or LN flare was lower with belimumab versus placebo in both subgroups. Belimumab was associated with improved kidney outcomes versus placebo with or without GC pulses at induction. CONCLUSION Data suggest consistent benefits of belimumab on kidney outcomes for newly diagnosed and relapsed patients, and irrespective of GC pulses at induction.

Abstract
OBJECTIVES To determine the safety and efficacy of anifrolumab in patients with systemic lupus erythematosus (SLE) classified based on the Lupus Low Disease Activity State (LLDAS) in real-world clinical practice. METHODS This retrospective observational study involved SLE patients who started anifrolumab therapy. The primary end point was the retention rate over 26 weeks after initiating anifrolumab therapy; 45 patients followed up for 12 weeks or longer were analyzed in the following groups to determine the safety and efficacy up to week 12 after treatment initiation: 1) non-LLDAS achievement group and 2) minor flare group. Safety and efficacy were compared between the minor flare group and the standard of care (SoC) group (treated by adding glucocorticoids (GCs) or immunosuppressants) after adjustment with inverse probability of treatment weighting using propensity score (PS-IPTW). RESULTS The retention rate of anifrolumab was 89.7% at week 26.The LLDAS achievement rates at week 12 were 42.9% and 66.7% in the non-LLDAS achievement and minor flare groups, respectively. In both groups, GC doses and SELENA-SLEDAI score significantly decreased. When the anifrolumab group with minor flare was compared with the SoC group or the GC dose increase group, the GC dose and SLEDAI score were significantly lower in the anifrolumab group than in both groups; there was no significant difference in LLDAS achievement. CONCLUSIONS At week 26 after initiating anifrolumab therapy, ∼90% patients remained on therapy. Anifrolumab might lower disease activity without initiating GCs and reduce GC doses, especially in patients who experience minor flares after LLDAS achievement.

Abstract
OBJECTIVE To elucidate the differential effects of biological/target synthesized DMARDs (b/tsDMARDs) on bone metabolism in patients with rheumatoid arthritis (RA) in a real-world cohort. METHODS This was a multicentre prospective observational study of RA patients enrolled at the time of 1st b/tsDMARDs administration. Bone mineral density (BMD) and bone turnover markers (BTMs) were measured during the 52-week observation. The study was designed to enrol all eligible RA patients. The end-points were differences in changes in BMD according to b/tsDMARD type, and the correlation between BMD and BTMs. RESULTS A total of 1,164 patients were enrolled in this study. b/tsDMARDs improved RA disease activity from mean CDAI 25.5 at baseline to 4.5 at week 26. Patients not receiving anti-osteoporotic agents (anti-OP) at baseline with no history of fracture experienced a significant decrease in both femoral neck (F: mean 0.666-0.655 g/cm3) and radial (R: 0.518-0.514) BMD at week 26. Despite maintaining low CDAI levels during weeks 26-52 (5.3-4.4), there was a continued decline in BMD (F: 0.653, R: 0.509. Weeks 52). None of b/tsDMARDs type preserved BMD. Conversely, patients receiving anti-OP at baseline maintained stable BMD throughout the study (Weeks 0/26/52. F: 0.551/0.551/0.555, R: 0.415/0.416/0.415). Although BTMs were changed by b/tsDMARDs, the changes were unrelated to those in BMD. CONCLUSION Our study suggested the progression of osteoporosis in RA patients during b/tsDMARDs treatment without anti-OP. BTMs may not reflect BMD change. Regular monitoring of BMD in RA should be considered for early management of osteoporosis.

Abstract
OBJECTIVES We aimed to identify associations between patterns of large-vessel lesions of large-vessel giant cell arteritis (LV-GCA) and treatment outcomes. METHODS We extracted data on 68 newly diagnosed patients with LV-GCA from a retrospective, multi-centric, nationwide registry of GCA patients treated with glucocorticoids between 2007 and 2014. Patients with aortic lesions were identified based on the findings from contrast-enhanced computed tomography, magnetic resonance imaging, or positron emission tomography-computed tomography (Group 2, n = 49). Patients without aortic lesions were subdivided into LV-GCA with or without subclavian lesions defined as Group 1 (n = 9) or Group 3 (n = 10), respectively. The primary outcome evaluation was failure to achieve clinical remission by Week 24 and/or relapse within 104 weeks. RESULTS The mean age and proportion of patients with cranial lesions and polymyalgia rheumatica in Group 2 were numerically lower than in the other two groups. Large-vessel lesions in Group 3 included carotid, pulmonary, renal, hepatic, or mesenteric lesions. The cumulative rate of poor treatment outcomes >2 years was 11.1%, 55.3%, and 88.0% in Groups 1, 2, and 3, respectively (by Kaplan-Meier analysis). The mean time to poor outcome was significantly different between the groups. CONCLUSIONS Classification by subclavian and aortic lesions may be useful to determine treatment strategy.

Abstract
OBJECTIVES Bimekizumab (BKZ) is a monoclonal IgG1 antibody that selectively inhibits interleukin (IL)-17F in addition to IL-17A. BKZ treatment has demonstrated superior efficacy versus placebo (PBO) at Week 16 in biologic disease-modifying antirheumatic drug (DMARD)-naïve patients with active psoriatic arthritis (PsA). Here, we report long-term efficacy and safety to Week 52. METHODS BE OPTIMAL comprised a 16-week, double-blind, PBO-controlled period, then 36 weeks treatment-blind. Patients were randomised 3:2:1 to subcutaneous BKZ 160 mg every 4 weeks, PBO with switch to BKZ at Week 16, or reference arm (adalimumab (ADA) 40 mg every 2 weeks). Efficacy outcomes included the American College of Rheumatology (ACR) response criteria 20/50/70, Psoriasis Area and Severity Index (PASI) 75/90/100 in patients with baseline psoriasis affecting ≥3% body surface area and minimal disease activity (MDA); non-responder imputation. RESULTS ACR20/50/70, PASI75/90/100 and MDA responses were sustained with BKZ to Week 52, consistent with results observed at Week 16. Patients who switched to BKZ at Week 16 demonstrated improvements in efficacy with similar results to BKZ-randomised patients by Week 52.To Week 52, 555/702 (79.1%) patients had ≥1 treatment-emergent adverse event (TEAE) during BKZ treatment; 113/140 (80.7%) on ADA. On BKZ, 46 (6.6%) patients had serious TEAEs. 54 (7.7%) Candida infections occurred during BKZ treatment and 1 (0.7%) during ADA; all cases were localised and non-serious. One death occurred in a BKZ-treated patient, unrelated to treatment. CONCLUSIONS The efficacy of BKZ in bDMARD-naïve patients with PsA was sustained from Week 16 to Week 52. BKZ was well tolerated with no new safety signals observed. TRIAL REGISTRATION NUMBER NCT03895203.

Effect of extended dosing interval of anti-TNF-alpha NANOBODY® compound ozoralizumab in patients with low disease activity rheumatoid arthritis. Mod Rheumatol 2023:road097. [PMID: 37804232 DOI: 10.1093/mr/road097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 09/16/2023] [Accepted: 09/29/2023] [Indexed: 10/09/2023]
Abstract
OBJECTIVE To evaluate the effect of extended dosing interval on the efficacy and safety of ozoralizumab in patients with rheumatoid arthritis (RA). METHODS In a long-term extension study (HOSHIZORA trial) for patients who had completed a phase II/III study with methotrexate (MTX) or a phase III study without MTX, the dosing interval of ozoralizumab was allowed to extend from every 4 weeks (Q4W) to every 8 weeks (Q8W), at the physician's discretion, for patients who had maintained DAS28-ESR <3.2 at the last two time points. The continuation rate, efficacy and safety were examined in patients who had completed 24 weeks after the change in the dosing interval by the data cut-off point. RESULTS Of the 32 patients who maintained DAS28-ESR <3.2 and changed the interval from Q4W to Q8W, 28 (87.5%) remained on Q8W for 24 weeks. At week 24, the percentages of patients who remained on Q8W and achieved DAS28-ESR <2.6 and <3.2 were 71.9% and 84.4%, respectively. No safety concerns were observed for 24 weeks in the Q8W group. CONCLUSIONS In patients with RA and maintained DAS28-ESR <3.2 with ozoralizumab, efficacy was sustained and well tolerated after the dosing interval was extended from Q4W to Q8W.

Abstract
Filgotinib is an orally administered, preferential Janus kinase (JAK) inhibitor indicated for the treatment of moderate-to-severe rheumatoid arthritis (RA). The short-term safety, efficacy, and patient-reported outcomes (PROs) with filgotinib from Phase 2b/3 clinical trials (DARWIN 1 and 2; FINCH 1, 2, and 3) are described in patients who inadequately responded to methotrexate (MTX) and biologic disease-modifying antirheumatic drugs or who were naïve to MTX. This article reviews the safety and efficacy from the long-term extension (LTE) trials, DARWIN 3 (N=739) and FINCH 4 (N=2731), and PROs across the filgotinib development program in RA. Overall, in the DARWIN clinical trials (conducted from 2013-2023), patients received their LTE treatment for ≤8 years, while in the FINCH trials (ongoing from 2016-2025), patients received filgotinib treatment for ≤6 years in the LTE. The longer-term safety profile and consistent, sustained efficacy (American College of Rheumatology 20/50/70, Clinical Disease Activity Index, and Disease Activity Scale in 28 joints with C-reactive protein response rates) of filgotinib were largely similar to those observed in the shorter-term parent trials ≤52 weeks. PRO results from the parent trials showed improvements in patients' quality of life with filgotinib treatment, which compared to or exceeded improvements seen with placebo and active comparators (adalimumab, MTX). Filgotinib has a higher specificity for JAK1 compared with other therapeutic treatments, leading to reduced inhibition of JAK2/3-dependent pathways, potentially providing a distinct safety profile. Filgotinib is approved in Europe and Japan for treatment of people with moderate-to-severe RA, though it has not been approved by the US Food and Drug Administration, due to concerns around the benefit/risk profile of the filgotinib 200-mg dosage and the potential impact on semen parameters.

Computed tomography for malignancy screening in patients with rheumatoid arthritis before initiation of disease modifying antirheumatic drug. Rheumatology (Oxford) 2023; 62:3339-3349. [PMID: 36782362 DOI: 10.1093/rheumatology/kead075] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Revised: 01/14/2023] [Accepted: 02/01/2023] [Indexed: 02/15/2023] Open
Abstract
OBJECTIVES This study aimed to clarify the usefulness of screening for malignancies using CT before the initiation of biologic and targeted synthetic DMARDs (b/tsDMARDs) in patients with active RA. METHODS We examined 2192 patients with RA who underwent plain CT scans prior to the initiation of b/tsDMARDs. The sensitivity for detecting malignancy was measured and compared with that of regular screening (physical examination and X-ray). We then evaluated the clinical characteristics, prognosis and treatment of patients with RA with concomitant malignancies. Additionally, we determined the incidence rate of malignancy in patients with RA who were initiated on b/tsDMARDs after CT screening. RESULTS Of the 2192 patients, 33 (1.5%) were diagnosed with malignancy after CT screening. Whereas regular screening detected only seven malignancies, CT screening further detected 26 (including 19 at the early stage). On the other hand, 86% of the malignancies detectable by regular screening were at an advanced stage. Patients diagnosed with early-stage malignancies received RA treatments that included b/tsDMARDs after curative resection; 80% of these patients achieved low disease activity after 1 year. This rate was comparable to the patients without malignancy detection after screening (70%). The 5 year incidence of malignancy after the initiation of b/tsDMARDs after CT screening was lower than that of the RA cohort without CT screening (standardized incidence ratio: 0.35). CONCLUSION Screening in patients with RA using CT before the initiation of b/tsDMARDs allows for the early detection and treatment of malignancy, resulting in safer and more stable b/tsDMARD treatments.

Abstract
OBJECTIVE This study aimed to seek a new method of evaluation and surrogate markers for diffuse neuropsychiatric SLE (NPSLE). METHODS We enrolled 44 patients with SLE between 2017 and 2020 who fulfilled at least one of three specific inclusion criteria: high disease activity, abnormal findings (cerebrospinal fluid [CSF] examination, brain MRI, or electroencephalography), or history of neuropsychiatric illness. Psychiatric symptom rating scales (PSYRATS) were evaluated retrospectively. The primary end point was the PSYRATS positivity rate in SLE patients who had not been diagnosed with diffuse NPSLE. RESULTS Based on the 1999 ACR classifications, 7 out of the 44 patients evaluated using PSYRATS had been diagnosed with diffuse NPSLE. PSYRATS positivity was seen in 13 out of 37 SLE patients (35.1%) who had not been diagnosed with diffuse NPSLE, and all these patients were positive for Montgomery-Åsberg Depression Rating Scale (MADRS), an indicator of depression state in PSYRATS. Additionally, in the 20 SLE patients exhibiting depression symptoms who were MADRS-positive, CSF concentrations of the neuroinflammatory markers homovanillic acid (HVA; P = 0.0400), stromal cell-derived factor-1α (SDF-1α; P = 0.0431) and stem cell growth factor-β (SCGF-1β; P = 0.0061) were significantly reduced compared with the 24 MADRS-negative SLE patients, and the levels of HVA, SDF-1α and SCGF-1β correlated with one another (P < 0.05). CONCLUSION Many patients with active SLE have subclinical depression, and MADRS evaluation of neuropsychiatric symptoms is useful for detecting them. Additionally, the decrease in CSF levels of HVA, SDF-1 α and SCGF-1β reflects the same pathology, and these may serve as surrogate markers.

Abstract
BACKGROUND To validate Japanese claims-based disease-identifying algorithms for herpes zoster (HZ), Mycobacterium tuberculosis (MTB), nontuberculous mycobacteria infections (NTM), and Pneumocystis jirovecii pneumonia (PJP). METHODS VALIDATE-J, a multicenter, cross-sectional, retrospective study, reviewed the administrative claims data and medical records from two Japanese hospitals. Claims-based algorithms were developed by experts to identify HZ, MTB, NTM, and PJP cases among patients treated 2012-2016. Diagnosis was confirmed with three gold standard definitions; positive predictive values (PPVs) were calculated for prevalent (regardless of baseline disease-free period) and incident (preceded by a 12-month disease-free period for the target conditions) cases. RESULTS Of patients identified using claims-based algorithms, a random sample of 377 cases was included: HZ (n = 95 [55 incident cases]); MTB (n = 100 [58]); NTM (n = 82 [50]); and PJP (n = 100 [84]). PPVs ranged from 67.4-70.5% (HZ), 67.0-90.0% (MTB), 18.3-63.4% (NTM), and 20.0-45.0% (PJP) for prevalent cases, and 69.1-70.9% (HZ), 58.6-87.9% (MTB), 10.0-56.0% (NTM), and 22.6-51.2% (PJP) for incident cases, across definitions. Adding treatment to the algorithms increased PPVs for HZ, with a small increase observed for prevalent cases of NTM. CONCLUSIONS VALIDATE-J demonstrated moderate to high PPVs for disease-identifying algorithms for HZ and MTB using Japanese claims data.

Abstract
Objective Currently, the most frequently prescribed once weekly glucagon-like peptide-1 receptor agonists (GLP-1RA) in Japan are dulaglutide (DG) and semaglutide (SG). However, little is known about the differences between these two compounds in clinical practice in Japan. This study compared the efficacy and safety of DG and SG using professional CGM in 12 patients attending our outpatient with poorly controlled type 2 diabetes mellitus (T2DM) while using GLP-1RA. Methods The study subjects were 12 T2DM patients with HbA1c ≥ 7.0% on treatment with 0.75 mg/week DG for at least 24 weeks. All patients wore the professional CGM twice, once while receiving DG and once when the SG dose was increased to 0.5 mg/week. Results Time in range was significantly better with SG than with DG, which was the main outcome measure. Regarding the secondary outcome measures, standard deviation of glucose, average sensor glucose, time above range, maximum sensor glucose, interquartile range, SD of glucose during the nocturnal period (0000-0559), and average nocturnal sensor glucose (0000-0559) were significantly better with SG than DG. In contrast, SG had no effect on the time below range and minimum sensor glucose compared to DG. Conclusions Switching from 0.75 mg DG to 0.5 mg SG in patients with T2DM improved glycemic variability, mean glycemic index, and daily variability without increasing the hypoglycemic index. The results suggest that switching to SG may be a useful option in patients experiencing inadequate glycemic control with DG.

Abstract
INTRODUCTION Our aim was to evaluate protein biomarker changes related to the administration of filgotinib, a Janus kinase (JAK) 1 preferential inhibitor, in patients with moderately to severely active rheumatoid arthritis (RA) with inadequate response to methotrexate. METHODS Plasma and serum samples were collected from patients enrolled in FINCH 1 (NCT02889796), a Phase 3 trial. Patients with stable backgrounds of methotrexate were randomly assigned once-daily oral filgotinib 200 or 100 mg, subcutaneous adalimumab 40 mg every 2 weeks (W), or placebo. Up to 35 biomarkers were analyzed at baseline, W4, and W12 with enzyme-linked immunosorbent assays and chemiluminescence and electrochemiluminescence assays. RESULTS At baseline, four distinct biomarker clusters were identified. The strongest intragroup correlations were in bone-cartilage resorption/inflammation and JAK/signal transducer and activator of transcription (STAT) signaling activity. At baseline, significant positive correlations were identified for cytokines with patient-reported pain and with patient measures of fatigue. Filgotinib reduced levels of cytokines associated with inflammation and cell migration as early as W4 and through W12. Compared to adalimumab, filgotinib induced significant reductions in bone-related turnover biomarkers, N-telopeptide of type 1 collagen and C-telopeptide 1, as well as biomarkers associated with baseline disease activity. No baseline predictors of therapeutic response to filgotinib were identified. CONCLUSIONS Filgotinib reduced peripheral protein biomarkers associated with JAK/STAT signaling, inflammatory signaling, immune cell migration, and bone resorption as soon as W4 in FINCH 1. Effects were dose-dependent and consistent with the clinical efficacy of filgotinib observed in FINCH 1. The changes in peripheral biomarkers associated with filgotinib treatment in methotrexate-experienced patients are consistent with changes observed in both methotrexate-naïve and biologic disease-modifying antirheumatic drug-experienced RA populations. These data demonstrate dose-dependent effects of preferential JAK1 inhibition by filgotinib on peripheral blood protein biomarkers in methotrexate-experienced patients with RA.

Treatment pattern and changes in oral glucocorticoid dose after tocilizumab treatment in patients with adult Still's disease: An analysis of a Japanese claims database. Int J Rheum Dis 2023; 26:1967-1978.

Abstract
AIM Intravenous tocilizumab (TCZ-IV) was approved for the treatment of adult Still's disease (ASD) in Japan in May 2019 based on its efficacy and safety in a phase III randomized controlled trial. This study determined treatment patterns in patients with ASD and assessed oral glucocorticoid (GC) dose changes after TCZ-IV administration in Japanese clinical practice. METHODS Patients in the Medical Data Vision database aged 16 years or older with one or more of International Classification of Diseases, 10th revision codes M061 (ASD) or M082 (systemic juvenile idiopathic arthritis) during January 2017-March 2021 (cohort 1) and those initiating TCZ-IV during May 2019-March 2021 (cohort 2) were included. RESULTS In cohort 1, the proportion of patients who were prescribed interleukin-6 inhibitors (mainly TCZ-IV) increased from 10.8% (January-April 2019 [before TCZ-IV approval]; n = 2002) to 18.3% (January-March 2021 [after TCZ-IV approval]; n = 2008). In cohort 2 (n = 193), 84.5% of patients were on oral GCs (≤5 mg/day: 23.8%) at index date (initial TCZ-IV prescription date); 46/70 (65.7%) were on oral GC at 5 mg/day or higher 12 months after TCZ-IV treatment (primary outcome). After 12 months of treatment, the TCZ-IV retention rate was 73.6% and the TCZ-IV administration interval was every 4 weeks and every 2 weeks in 31.9% and 27.7% of patients, respectively. CONCLUSION The use of interleukin-6 inhibitors increased by 7.5% points in Japanese patients with ASD ~2 years after TCZ-IV approval, suggesting that an unmet medical need existed. This study suggests the potential GC-sparing effect of TCZ-IV in patients with ASD in clinical practice.

Abstract
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
BACKGROUND Targets of treatment for systemic lupus erythematosus (SLE) include the Lupus Low Disease Activity State (LLDAS), remission, and complete remission. Whether treatment can be tapered after attaining these targets and whether tapering is safer in patients in complete remission compared with LLDAS are unknown. We aimed to assess the odds of disease flares after treatment tapering in stable disease, versus continuing the same therapy. We also aimed to examine whether tapering in complete remission resulted in fewer flares or longer time to flare compared with tapering in LLDAS or remission. METHODS This multinational cohort study was conducted at 25 sites across 13 Asia-Pacific countries. We included adult patients aged 18 years or older with stable SLE who were receiving routine clinical care, had two or more visits and had attained stable disease at one or more visits. We categorised stable disease into: LLDAS (Systemic Lupus Erythematosus Disease Activity Index 2000 [SLEDAI-2K] score ≤4, Physician Global Assessment [PGA] ≤1, and prednisolone ≤7·5 mg/day); Definitions of Remission in SLE (DORIS) remission (clinical SLEDAI-2K score 0, PGA <0·5, and prednisolone ≤5 mg/day); or complete remission on therapy (SLEDAI-2K score 0, PGA <0·5, and prednisolone ≤5 mg/day). Stable disease categories were mutually exclusive. Tapering was defined as any decrease in dose of corticosteroids or immunosuppressive therapy (mycophenolate mofetil, calcineurin inhibitors, azathioprine, leflunomide, or methotrexate). Using multivariable generalised estimating equations, we compared flares (SELENA-SLEDAI Flare Index) at the subsequent visit after drug tapering. We used generalised estimating equations and Cox proportional hazard models to compare tapering attempts that had begun in LLDAS, remission, and complete remission. FINDINGS Between May 1, 2013, and Dec 31, 2020, 4106 patients were recruited to the cohort, 3002 (73·1%) of whom were included in our analysis. 2769 (92·2%) participants were female, 233 (7·8%) were male, and 2636 (88·1%) of 2993 with ethnicity data available were Asian. The median age was 39·5 years (IQR 29·0-50·0). There were 14 808 patient visits for patients in LLDAS, or remission or complete remission, of which 13 140 (88·7%) entered the final multivariable model after excluding missing data. Among the 9863 visits at which patients continued the same therapy, 1121 (11·4%) flared at the next visit, of which 221 (19·7%) were severe flares. Of the 3277 visits at which a patient received a tapering of therapy, 557 (17·0%) flared at the next visit, of which 120 (21·5%) were severe flares. Tapering was associated with higher odds of flare compared with continuing the same therapy (odds ratio [OR] 1·24 [95% CI 1·10-1·39]; p=0·0005). Of 2095 continuous tapering attempts, 860 (41·1%) were initiated in LLDAS, 596 (28·4%) in remission, and 639 (30·5%) in complete remission. Tapering initiated in LLDAS (OR 1·37 [95% CI 1·03-1·81]; p=0·029) or remission (1·45 [1·08-1·94]; p=0·013) had higher odds of flare in 1 year compared with complete remission. Tapering in LLDAS (hazard ratio 1·24 [95% CI 1·04-1·48]; p=0·016) or remission (1·30 [1·08-1·56]; p=0·0054) had a significantly shorter time to first flare than tapering initiated in complete remission. Attaining sustained LLDAS, remission, or complete remission for at least 6 months just before the time of taper was associated with lower odds of flare at next visit, flares in 1 year, and longer time to flare. INTERPRETATION Tapering of corticosteroids or immunosuppressive therapy in patients with stable SLE was associated with excess flares. Our findings suggest that drug tapering should be carefully considered, weighing the risks and benefits, and is best exercised in complete (clinical and serological) remission and after maintaining stable disease for at least 6 months.

[PMID: 37706527 DOI: 10.1093/mr/road092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 08/29/2023] [Accepted: 09/11/2023] [Indexed: 09/15/2023]
Abstract
OBJECTIVES Evaluate the long-term safety and tolerability of anifrolumab 300 mg, alongside standard therapy, in patients from Japan with systemic lupus erythematosus (SLE) in the TULIP-LTE trial (NCT02794285). METHODS TULIP-LTE was a 3-year, randomized, double-blind, placebo-controlled long-term extension (LTE) of the TULIP trials. The primary safety outcome included serious adverse events (SAEs) and AEs of special interest (AESIs) during the LTE period. Exploratory efficacy outcomes included SLE Disease Activity Index 2000 (SLEDAI-2K) scores and glucocorticoid use. We performed a post hoc subgroup analysis of patients who enrolled in Japan. RESULTS Exposure-adjusted incidence rates of SAEs during the LTE and follow-up for patients receiving anifrolumab 300 mg (n=21) were 8.7 per 100 patient-years; AESIs included influenza (6.9) and herpes zoster (3.5). One of three patients receiving placebo had an SAE (13.9). One patient per group discontinued due to an AE. There were no deaths. During the TULIP+LTE period, patients receiving anifrolumab 300 mg (n=24) had sustained reduction from baseline in mean SLEDAI-2K scores and cumulative glucocorticoid dosage. CONCLUSIONS Anifrolumab 300 mg showed a favourable benefit-risk profile for the long-term treatment of adult patients with moderate to severe SLE from Japan, with safety, tolerability, and efficacy profiles consistent with the overall population.

Abstract
INTRODUCTION The molecular targeted therapies available for rheumatoid arthritis include 10 types of biological disease-modifying antirheumatic drugs (bDMARDs) and five types of Janus kinase (JAK) inhibitors. This article reviews the differential and proper use of bDMARDs and JAK inhibitors, focusing on their efficacy and safety, based mainly on phase III clinical trials. AREA COVERED The JAK inhibitors approved for treating rheumatoid arthritis are compared with bDMARDs based on the evidence derived from global phase III trials. EXPERT OPINION In patients with inadequate responses to bDMARDs and JAK inhibitors, switching between these drugs is comparable in efficacy in both directions. Head-to-head comparison demonstrated that baricitinib and upadacitinib are more efficacious than tumor necrosis factor (TNF) inhibitors. However, the ORAL Surveillance study demonstrated that JAK inhibitors are associated with higher incidences of death, major adverse cardiovascular events, malignancies and thrombosis than TNF inhibitors in at-risk patients. The need for risk assessment by pre-treatment screening, regular monitoring during treatment, and appropriate systemic management in adverse events should be recognized. Meanwhile, some JAK-inhibitors were efficacious even for difficult-to-treat disease. These results suggest the need for establishing therapeutic strategies considering the balance between safety and efficacy in individual patients.

Abstract
Systemic lupus erythematosus (SLE) is a disease of high unmet therapeutic need. The challenge of accurately measuring clinically meaningful responses to treatment has hindered progress towards positive outcomes in SLE trials, impeding the approval of potential new therapies. Current primary end points used in SLE trials are based on legacy disease activity measures that were neither specifically designed for the clinical trial context, nor developed according to contemporary recommendations for clinical outcome assessments (COAs), such as that substantial patient input should be incorporated into their design. The Treatment Response Measure for SLE (TRM-SLE) Taskforce is a global collaboration of SLE clinician-academics, patients and patient representatives, industry partners and regulatory experts, established to realize the goal of developing a new COA for SLE clinical trials. The aim of this project is a novel COA designed specifically to measure treatment effects that are clinically meaningful to patients and clinicians, and intended for implementation in a trial end point that supports regulatory approval of novel therapeutic agents in SLE. This Consensus Statement reports the first outcomes of the TRM-SLE project, including a structured process for TRM-SLE development.

Abstract
OBJECTIVES The aim is to assess the efficacy and safety of a 52-week subcutaneous ozoralizumab treatment at 30 and 80 mg without methotrexate (MTX) in active rheumatoid arthritis. METHODS This randomised, open-label, multicentre phase III trial randomly allocated 140 patients in 2:1 ratio as subcutaneous ozoralizumab at 30 or 80 mg every 4 weeks for 52 weeks without MTX. RESULTS Both groups administered ozoralizumab at 30 and 80 mg showed good clinical improvement. The American College of Rheumatology response rates were high at Week 24 and maintained through 52 weeks. The ozoralizumab groups also showed good improvement in other end points, and improvements observed from Week 1 were maintained through 52 weeks. Improvements in many efficacy assessments were similar between doses. No deaths were reported, and serious adverse events occurred in a total of 20 patients in the ozoralizumab groups. Increased antidrug antibodies were observed in approximately 40% of patients in the ozoralizumab groups, and 27.7% of the patients in the 30 mg group were neutralising antibody-positive. CONCLUSIONS Ozoralizumab, at 30 and 80 mg, demonstrated significant therapeutic effects without MTX, and the efficacy was maintained for 52 weeks with active rheumatoid arthritis. Ozoralizumab showed an acceptable tolerability profile over 52 weeks.

Abstract
OBJECTIVE To assess the efficacy and safety through a 52-week treatment with subcutaneous ozoralizumab at 30 or 80 mg in patients with active rheumatoid arthritis despite methotrexate therapy. METHODS This multicentre, randomized, placebo-controlled, double-blind, parallel-group confirmatory trial included a 24-week double-blind treatment period followed by a 28-week open-label treatment period. The double-blind treatment period randomized 381 (2:2:1) patients to placebo and ozoralizumab at 30 or 80 mg, and patients receiving placebo were re-randomized (1:1) to ozoralizumab at 30 or 80 mg in the open-label period. RESULTS The ozoralizumab groups showed good clinical improvement, with high American College of Rheumatology response rates at 52 weeks, as well as good improvements in other endpoints, which were observed from Day 3 and maintained through Week 52. Furthermore, the ozoralizumab groups showed a high remission rate in clinical and functional remission at Week 52. Serious adverse events occurred in a total of 23 patients in the ozoralizumab groups, without differences in incidence between doses. CONCLUSIONS Ozoralizumab demonstrated significant therapeutic effects and efficacy, which was maintained for 52 weeks. The safety profile was consistent with the evaluated results in interim analysis at Week 24, and ozoralizumab was well-tolerated up to Week 52.

Abstract
Type I interferons (IFNs) have recently received a lot of attention with the elucidation of the pathogenesis of systemic lupus erythematosus (SLE). Type I IFNs are associated with many SLE symptoms and play a role in the pathogenesis of autoimmune diseases that may occur concurrently with SLE, such as Sjögren's syndrome, antiphospholipid syndrome, myositis, scleroderma, and interferonopathy. Type I IFNs could be the link between these diseases. However, direct measurement of type I IFN levels and the IFN gene signature is currently unavailable in clinical practice. This review discusses type I IFN signalling in SLE, investigates the role of type I IFN in the clinical manifestations and symptoms associated with SLE and other IFN-related diseases, and discusses the clinical tests that can be used to diagnose SLE and measure disease activity. In addition, the role of type I IFN-blocking therapies as potential treatments for SLE is discussed.

Abstract
OBJECTIVE The aim of this study is to investigate the effects of sarilumab on unacceptable pain [UP; visual analogue scale (VAS) >40 mm] and inflammation in patients with moderately-to-severely active rheumatoid arthritis. METHODS In this post hoc analysis of the KAKEHASI study, 243 patients received methotrexate with sarilumab 150 or 200 mg or placebo every other week, over 52 weeks. The proportion of patients with UP and correlations of changes in pain VAS from baseline with uncontrolled inflammation (C-reactive protein ≥1 mg/dl) and disease activity indices were assessed. RESULTS Almost 80% of patients (192/243) had UP at baseline, including ∼60% of patients with uncontrolled inflammation. Among patients receiving sarilumab, inflammation decreased rapidly, with 90% of patients achieving controlled inflammation by Week 2, while 63.1% continued to have UP. The proportion of patients with UP further decreased by Week 16 (28.5%, sarilumab vs. 64.0%, placebo). By Week 52, only ∼10% of patients had UP. Changes in pain VAS correlated with most disease activity indices and patient-reported outcomes. However, marked correlations between changes in pain VAS and C-reactive protein were observed only at Week 16. CONCLUSION Sarilumab treatment reduced UP and inflammation in Japanese patients with rheumatoid arthritis.

Abstract
OBJECTIVE To examine the efficacy and safety of TAS5315, an irreversible covalent Bruton's tyrosine kinase inhibitor, in Japanese patients with rheumatoid arthritis (RA) refractory to methotrexate. METHODS In part A of this phase IIa double-blind study, patients were randomised to TAS5315 4 or 2 mg or placebo once daily for 12 weeks; in part B, all patients received TAS5315 for another 24 weeks. The proportion of patients meeting American College of Rheumatology criteria for 20% improvement (ACR20) at week 12 was assessed (primary endpoint). RESULTS Ninety-one patients were randomised in part A, and 84 entered part B. At week 12, 78.9% of patients achieved ACR20 in the TAS5315 combined group vs 60.0% with placebo (p=0.053), 33.3% vs 13.3% achieved ACR50 (p=0.072) and 7.0% vs 0.0% achieved ACR70 (p=0.294), respectively. More patients receiving TAS5315 than placebo had low disease activity or remission at week 12. Clinical and biomarker improvements were maintained during part B. Adverse event (AE) incidence in TAS5315 was similar to placebo in part A; common AEs with TAS5315 were nasopharyngitis (10.3%), pruritus (6.9%) and cystitis (5.2%). Over 36 weeks, nine patients experienced bleeding events of whom four and two patients recovered with drug continuation and interruption, respectively. Three patients recovered after TAS5315 discontinuation. CONCLUSIONS The primary endpoint was not achieved. TAS5315 appears to have some bleeding risks, but nevertheless demonstrated numerical differences, compared with placebo, in the improvement rates of all measures of RA disease activity. Future analysis of the risk-benefit of TAS5315 should be considered. TRIAL REGISTRATION NUMBERS NCT03605251, JapicCTI-184020, jRCT2080223962.

Abstract
Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease characterised by unpredictable flares. Many patients with SLE are unable to achieve the recommended treatment goal of remission or the intermediate, yet still clinically beneficial, goal of Lupus Low Disease Activity State (LLDAS) with standard of care (SoC) treatments. LLDAS is an emerging treat-to-target goal in SLE with the aim of reducing organ damage and mortality. A high unmet need remains in SLE and mainstay glucocorticoid treatment is associated with unacceptable toxicity. The recently approved type I interferon receptor antagonist anifrolumab is a new treatment option for this historically underserved patient population. In phase 3 trials, a higher percentage of patients on anifrolumab achieved remission, as defined by the Definition Of Remission In SLE (DORIS), and LLDAS compared with placebo. Real-world clinical experience with anifrolumab use is still limited. Until real-world study results and updated treatment guidelines are available, personal expert clinical experience supported by data may inform clinical decision-making. This viewpoint article discusses four example patient types that could be considered for anifrolumab treatment based on (1) high-risk features early in the disease course, (2) inability to achieve and (3) maintain at least LLDAS, or (4) a desire to reduce or stop SoC. These patients with high unmet need may benefit from the addition of anifrolumab to SoC to achieve or maintain the therapeutic goals of LLDAS or DORIS remission.

Abstract
OBJECTIVES To assess the safety of the oral Janus kinase inhibitor baricitinib in adult patients with systemic lupus erythematosus (SLE) receiving stable background therapy. Topics of special interest included infections and cardiovascular and thromboembolic events. METHODS This analysis included integrated safety data from three randomised, placebo-controlled studies (one phase 2 and two phase 3) and one long-term extension study. Data are reported in three data sets: placebo-controlled, extended exposure and all-baricitinib. Outcomes include treatment-emergent adverse events (AEs), AEs of special interest and abnormal laboratory changes. Proportions of patients with events and incidence rates (IRs) were calculated. RESULTS A total of 1655 patients received baricitinib for up to 3.5 years (median duration 473 days). With baricitinib 4 mg, baricitinib 2 mg and placebo, respectively, 50.8%, 50.7% and 49.0% of patients reported at least one infection and 4.4%, 3.4% and 1.9% of patients had a serious infection. The most common treatment-emergent infections included urinary tract infection, COVID-19, upper respiratory tract infection and nasopharyngitis. Herpes zoster was more common with baricitinib 4 mg (4.7%) vs baricitinib 2 mg (2.7%) and placebo (2.8%). Among baricitinib-4 mg, 2 mg and placebo-treated patients, respectively, 4 (IR=0.9), 1 (IR=0.2) and 0 experienced at least one positively adjudicated major adverse cardiovascular event, and 0, 3 (IR=0.6) and 2 (IR=0.4) reported at least one positively adjudicated venous thromboembolism. CONCLUSIONS The results of this integrated safety analysis in patients with SLE are not substantially different to the established safety profile of baricitinib. No increased venous thromboembolism was found.

Abstract
INTRODUCTION Ozoralizumab (Nanozora), a novel TNF inhibitor, was first approved in Japan in September 2022 as a next-generation antibody for the treatment of rheumatoid arthritis (RA). Ozoralizumab potently inhibits TNF action through two human TNFα-binding domains, and a human serum albumin-binding domain that prolongs its plasma half-life enabling 4-week administration intervals. Its molecular weight is 38 kDa, which is one-fourth that of the conventional immunoglobulin G. AREAS COVERED Structural characteristics of ozoralizumab, preclinical findings, clinical data, and its recommended positioning in current RA treatments have been summarized. EXPERT OPINION Studies using mouse models have shown the rapid distribution of ozoralizumab in inflamed joint tissues, presumably because of its small molecular size and albumin-binding action. In clinical studies, remarkable improvements in clinical symptoms and patient-reported outcomes were observed 2 days after subcutaneous administration of 30 mg ozoralizumab with concurrent methotrexate therapy. Moreover, the efficacy and tolerability of the drug for up to 52 weeks, with or without methotrexate, were confirmed. Ozoralizumab is expected to be a highly practical option for patients with RA as a new type of TNF inhibitor with early symptom improvement despite subcutaneous administration.

Abstract
Baricitinib, an oral selective Janus kinase (JAK)1/JAK2 inhibitor, is approved as monotherapy or in combination with methotrexate for treating adults with moderate-to-severe active rheumatoid arthritis (RA) and provides improvements in clinical signs, symptoms and patient-reported outcomes. Currently, baricitinib is approved for treating RA in more than 75 countries. In several pivotal Phase II and III RA trials (RA-BALANCE, RA-BEGIN, RA-BEAM, RA-BUILD, RA-BEACON, RA-BEYOND), up to seven years of baricitinib treatment was well tolerated and provided rapid and sustained efficacy, which was confirmed in real-world settings. Safety signals for another JAK inhibitor, tofacitinib, have emerged, as observed in the post-marketing Phase IIIb/IV trial Oral Rheumatoid Arthritis Trial (ORAL) Surveillance; safety signals were subsequently highlighted in a retrospective study of baricitinib and consequently new recommendations and warnings and precautions for all JAK inhibitors have been issued. Ongoing studies to further characterise and clarify the benefit:risk of JAK inhibitors include registries and controlled trials. This capstone review summarises clinical and real-world data outlining the benefit:risk profile of baricitinib, confirming that the improved disease activity and physical function of patients with RA treated with this JAK inhibitor observed in clinical trials is translated into effectiveness in clinical practice, with a low rate of discontinuations.

Abstract
Although it is known that psoriasis is strongly associated with obesity, the mechanistic connection between diet and skin lesions is not well established. Herein, we showed that only dietary fat, not carbohydrates or proteins, exacerbates psoriatic disease. Enhanced psoriatic skin inflammation was associated with changes in the intestinal mucus layer and microbiota composition by high-fat diet (HFD). Change of intestinal microbiota by vancomycin treatment effectively blocked activation of psoriatic skin inflammation by HFD, inhibited the systemic interleukin-17 (IL-17) response, and led to increased mucophilic bacterial species such as Akkermansia muciniphila. By using IL-17 reporter mice, we could show that HFD facilitates IL-17-mediated γδ T cell response in the spleen. Notably, oral gavage with live or heat-killed A. muciniphila effectively inhibited HFD-induced enhancement of psoriatic disease. In conclusion, HFD exacerbates psoriatic skin inflammation through changing the mucus barrier and the intestine microbial composition, which leads to an enhanced systemic IL-17 response.

OBJECTIVES T peripheral helper (Tph) cells have major roles in pathological processes in SLE. We sought to clarify the mechanisms of Tph cell differentiation and their relevance to clinical features in patients with SLE. METHOD Phenotypes and functions of Tph cell-related markers in human CD4+ T cells purified from volunteers or patients were analysed using flow cytometry and quantitative PCR. Renal biopsy specimens from patients with LN were probed by multicolour immunofluorescence staining. RESULTS Among multiple cytokines, transforming growth factor (TGF)-β3 characteristically induced programmed cell death protein 1 (PD-1)hi musculoaponeurotic fibrosarcoma (MAF)+, IL-21+IL-10+ Tph-like cells with a marked upregulation of related genes including PDCD-1, MAF, SOX4 and CXCL13. The induction of Tph-like cells by TGF-β3 was suppressed by the neutralization of TGF-β type II receptor (TGF-βR2). TGF-β3-induced Tph-like cells efficiently promoted the differentiation of class-switch memory B cells into plasmocytes, resulting in enhanced antibody production. The proportion of Tph cells in the peripheral blood was significantly increased in patients with SLE than in healthy volunteers in concordance with disease activity and severity of organ manifestations such as LN. TGF-β3 was strongly expressed on macrophages, which was associated with the accumulation of CD4+ C-X-C chemokine receptor (CXCR5)-PD-1+ Tph cells, in the renal tissue of patients with active LN. CONCLUSION The induction of Tph-like cells by TGF-β3 mainly produced from tissue macrophages plays a pivotal role in the pathological processes of active LN by enhancing B-cell differentiation in patients with SLE.

Abstract
INTRODUCTION Rheumatoid arthritis (RA) is an autoimmune disorder necessitating immunosuppressive therapy. Remarkable progress has been made in the treatment of RA over recent decades, particularly with the development of biological disease-modifying antirheumatic drugs (bDMARDs) and Janus kinase inhibitors (JAKi). Nonetheless, the development of new drugs has been accompanied by concerns regarding the association between these novel therapies and the risk of malignancy. AREAS COVERED This narrative review aims to discuss the understanding of RA, conventional synthetic (cs) DMARDs, bDMARDs, JAKi, and their association with malignancy. Furthermore, the review discusses the management of malignancy in patients receiving b/tsDMARDs. EXPERT OPINION Although recent studies suggest that the potential risk of malignancy of methotrexate and a JAKi tofacitinib, it is essential to avoid indiscriminate withholding of treatment by those agents, as this may lead functional impairment and increased mortality. Therefore, the adoption of a Treat-to-Target (T2T) approach considering individual patient characteristics, becomes of utmost importance. Rheumatologists should maintain a vigilant stance regarding malignancy in this context, recognizing the importance of early detection and management. Implementing a screening program for malignancies is indispensable, and the use of computed tomography screening may enhance the effectiveness of management strategies.

Differential expression of IFN-α, IL-12 and BAFF on renal immune cells and its relevance to disease activity and treatment responsiveness in patients with proliferative lupus nephritis. Lupus Sci Med 2023; 10:e000962. [PMID: 37460249 PMCID: PMC10357699 DOI: 10.1136/lupus-2023-000962] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Accepted: 06/13/2023] [Indexed: 07/20/2023]
Abstract
OBJECTIVE Since molecularly targeted therapies are emerging for treating lupus nephritis (LN), this study aimed to assess the immunohistochemical findings of the cytokines in renal tissue and their pathological and clinical relevance in LN. METHODS Fifty patients with proliferative LN formed the case group; 5 with LN class II, IgA nephropathy and 10 with idiopathic haematuria were enrolled as controls. Immunohistochemical analysis for CD3, CD20, interferon (IFN)-α, interleukin (IL)-12/p40 and B-cell activating factor (BAFF) was performed by scoring the number of positive cells/area of the cortex. All immunohistochemical investigations were performed on formalin-fixed paraffin-embedded renal tissue. Proliferative LN cases were grouped by the dominant expression of IFN-α, IL-12/p40 and BAFF, and subsequently, clinicopathological features were compared. RESULTS Clinical data of patients with proliferative LN included urine protein creatinine ratio, 2.2 g/gCre; anti-double-stranded DNA antibody, 200.9 IU/mL; total complement activity (CH50), 21.9 U/mL and SLE Disease Activity Index, 19.8 points. Proliferative LN cases, including class III (n=18) and IV (n=32), were classified into three subgroups according to the immunohistochemical score based on the dominancy of IFN-α (n=17), IL-12 (n=16) and BAFF group (n=17) proteins. Hypocomplementaemia and glomerular endocapillary hypercellularity were significantly increased in the IFN-α group, whereas chronic lesions were significantly higher in the IL-12 group (p<0.05). The IFN-α group had a poorer renal prognosis in treatment response after 52 weeks. CONCLUSIONS The immunohistochemistry (IHC) of IFN-α, IL-12 and BAFF for proliferative LN enabled grouping. Especially, the IFN-α and IL-12 groups showed different clinicopathological features and renal prognoses. The results indicated the possibility of stratifying cases according to the IHC of target molecules, which might lead to precision medicine.

Abstract
INTRODUCTION Glucocorticoids and immunosuppressants are used to treat systemic lupus erythematosus (SLE). However, patients with SLE have poor long-term prognoses. This can be attributed to organ damage caused by flare-ups and drug toxicity due to the administration of nonspecific treatment. Therefore, SLE should be treated using therapeutic agents specific to its pathology. Janus kinase (JAK) inhibitors exert multitargeted effects by blocking the signaling of multiple cytokines. The use of JAK inhibitors has been approved to treat several inflammatory autoimmune diseases. Several clinical trials of JAK inhibitors for SLE treatment are ongoing. AREA COVERED This review summarizes the basic and clinical significance of JAK inhibitors for treating SLE and the current status of the development of JAK inhibitors based on recent reports. EXPERT OPINION SLE is a clinically and immunologically heterogeneous disease. Therefore, drugs targeting a single molecule require precision medicine to exert maximal therapeutic efficacy. JAK inhibitors can probably fine-tune the immune network via various mechanisms and broadly regulate complex immune-mediated pathologies in SLE. However, evidence is required to address some safety concerns associated with the use of JAK inhibitors in patients with SLE, including infections (particularly herpes zoster) and thromboembolism (particularly in the presence of concomitant antiphospholipid syndrome).

Abstract
The treatment of rheumatoid arthritis was revolutionized with the use of molecular-targeted drugs that target immunoregulatory molecules. The success of treatment with these drugs prompted the development of molecular-targeted drugs for systemic lupus erythematosus. However, systemic lupus erythematosus is a disease with high heterogeneous immune abnormalities, and diverse cells or molecules can be treatment targets. Thus, the identification of subpopulations based on immune abnormalities is essential for the development of effective treatment. One analytical method used to identify subpopulations is the immunophenotyping of peripheral blood samples of patients. This analysis evaluates the validity of target molecules for peripheral blood immune cell subsets, which are expected to be developed as biomarkers for precision medicine in which appropriate treatment targets are set for each subpopulation.

Abstract
We extend gigahertz time-domain imaging to a wideband investigation of the eigenstates of a phononic crystal cavity. Using omnidirectionally excited phonon wave vectors, we implement an ultrafast technique to experimentally probe the two-dimensional acoustic field inside and outside a hexagonal cavity in a honeycomb-lattice phononic crystal formed in a microscopic crystalline silicon slab, thereby revealing the confinement and mode volumes of phonon eigenstates-some of which are clearly hexapole in character-lying both inside and outside the phononic-crystal band gap. This allows us to obtain a quantitative measure of the spatial acoustic energy storage characteristics of a phononic crystal cavity. We also introduce a numerical approach involving toneburst excitation and the monitoring of the acoustic energy decay together with the integral of the Poynting vector to calculate the Q factor of the principal in-gap eigenmode, showing it to be limited by ultrasonic attenuation rather than by phonon leakage to the surrounding region.

Abstract
AIM Certolizumab pegol (CZP), an Fc-free, PEGylated tumor necrosis factor inhibitor (TNFi), has shown rapid and sustained reduction in signs and symptoms of rheumatoid arthritis (RA). Elevated rheumatoid factor (RF) level has been associated with RA disease progression and poorer TNFi response. We assessed the efficacy of CZP in patients with early and established RA across baseline RF levels. METHODS This post-hoc analysis included data from 6 trials: C-OPERA (NCT01451203), pooled RAPID trials (RAPID-1 [NCT00152386], RAPID-2 [NCT00160602], J-RAPID [NCT00791999], RAPID-C [NCT02151851]), and EXXELERATE (NCT01500278). Patients who received CZP or placebo/comparator with methotrexate (MTX) were categorized by baseline RF quartiles. Efficacy was assessed with Disease Activity Score-28 erythrocyte sedimentation rate (DAS28-ESR). RESULTS Overall, 316, 1537, and 908 patients were included in C-OPERA, pooled RAPID trials, and EXXELERATE, respectively. Patient demographics and baseline disease characteristics were similar between treatment groups and across RF quartiles. DAS28-ESR low disease activity (LDA) and remission (REM) rates were numerically higher in the CZP + MTX group than PBO + MTX group at weeks 12 and 24, across RF quartiles. LDA and REM rates in the CZP + MTX groups were comparable across RF quartiles at weeks 12 and 24. Mean DAS28-ESR decreased from week 0 to week 24 in the CZP + MTX groups, across RF quartiles. CONCLUSION CZP showed steady efficacy across baseline RF quartiles in patients with early and established RA, over 24 weeks. CZP treatment may be considered in patients with RA irrespective of baseline RF levels and time from diagnosis.

Abstract
Systemic lupus erythematosus (SLE) is an inflammatory autoimmune disease involving multiple organs in which B cells perform important functions such as antibody and cytokine production and antigen presentation. B cells are activated and differentiated by the primary B cell receptor, co-stimulatory molecule signals-such as CD40/CD40L-, the Toll-like receptors 7,9, and various cytokine signals. The importance of immunometabolism in the activation, differentiation, and exerting functions of B cells and other immune cells has been widely reported in recent years. However, the regulatory mechanism of immunometabolism in B cells and its involvement in SLE pathogenesis remain elusive. Similarly, the importance of the PI3K-Akt-mTOR signaling pathway, glycolytic system, and oxidative phosphorylation has been demonstrated in the mechanisms of B cell immunometabolic activation, mainly in mouse studies. However, the activation of the mTOR pathway in B cells in patients with SLE, the induction of plasmablast differentiation through metabolic and transcription factor regulation by mTOR, and the involvement of this phenomenon in SLE pathogenesis are unclear. In our studies using activated B cells derived from healthy donors and from patients with SLE, we observed that methionine, an essential amino acid, is important for mTORC1 activation. Further, we observed that splenic tyrosine kinase and mTORC1 activation synergistically induce EZH2 expression and plasmablasts by suppressing BACH2 expression through epigenomic modification. Additionally, we identified another mechanism by which the glutaminolysis-induced enhancement of mitochondrial function promotes plasmablast differentiation in SLE. In this review, we focused on the SLE exacerbation mechanisms related to the activation of immune cells-especially B cells-and immunometabolism and reported the latest findings in the field.

The trajectory of clinical responses in patients with early rheumatoid arthritis who achieve sustained remission in response to abatacept: subanalysis of AVERT-2, a randomized phase IIIb study. Arthritis Res Ther 2023; 25:67. [PMID: 37087459 PMCID: PMC10122306 DOI: 10.1186/s13075-023-03038-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Accepted: 03/27/2023] [Indexed: 04/24/2023] Open
Abstract
BACKGROUND AVERT-2 (a phase IIIb, two-stage study) evaluated abatacept + methotrexate versus methotrexate alone, in methotrexate-naive, anti-citrullinated protein antibody-positive patients with early (≤ 6 months), active RA. This subanalysis investigated whether individual patients who achieved the week 24 Simplified Disease Activity Index (SDAI) remission primary endpoint could sustain remission to 1 year and then maintain it following changes in therapy. METHODS During the 56-week induction period (IP), patients were randomized to weekly subcutaneous abatacept 125 mg + methotrexate or abatacept placebo + methotrexate. Patients completing the IP who achieved SDAI remission (≤ 3.3) at weeks 40 and 52 entered a 48-week de-escalation (DE) period. Patients treated with abatacept + methotrexate were re-randomized to continue weekly abatacept + methotrexate, or de-escalate and then withdraw abatacept (after 24 weeks), or receive abatacept monotherapy. Proportions of patients achieving sustained SDAI and Boolean remission, and Disease Activity Score in 28 joints using C-reactive protein (DAS28 [CRP]) < 2.6, were assessed. For patients achieving early sustained SDAI remission at weeks 24/40/52, flow between disease activity categories and individual trajectories was evaluated; flow was also evaluated for later remitters (weeks 40/52 but not week 24). RESULTS Among patients treated with abatacept + methotrexate (n/N = 451/752) at IP week 24, 22% achieved SDAI remission, 17% achieved Boolean remission, and 42% achieved DAS28 (CRP) < 2.6; of these, 56%, 58%, and 74%, respectively, sustained a response throughout IP weeks 40/52. Among patients with a sustained response at IP weeks 24/40/52, 82% (14/17) on weekly abatacept + methotrexate, 81% (13/16) on abatacept monotherapy, 63% (12/19) who de-escalated/withdrew abatacept, and 65% (11/17) on abatacept placebo + methotrexate were in SDAI remission at end of the DE period; rates were higher than for later remitters in all arms except abatacept placebo + methotrexate. CONCLUSIONS A high proportion of individual patients achieving clinical endpoints at IP week 24 with abatacept + methotrexate sustained their responses through week 52. Of patients achieving early and sustained SDAI remission through 52 weeks, numerically more maintained remission during the DE period if weekly abatacept treatment continued.

Abstract
INTRODUCTION Ozoralizumab (OZR), a tumor necrosis factor alpha (TNFα) inhibitor, is a NANOBODY® compound that binds to TNFα and human serum albumin. The main objective of this study was to analyze the pharmacokinetics (PK) of the drug and its correlation with clinical efficacy in patients with rheumatoid arthritis (RA). METHODS Efficacy data were analyzed from the OHZORA trial, in which OZR 30 or 80 mg was administered to Japanese patients with RA at 4-week intervals for 52 weeks in combination with methotrexate (MTX; n = 381), and the NATSUZORA trial, in which OZR 30 or 80 mg was administered without concomitant MTX (n = 140). Effects of patient baseline characteristics and anti-drug antibodies (ADAs) on the PK and efficacy of OZR were investigated, and a post hoc analysis of PK effects on drug efficacy was performed. RESULTS The maximum plasma concentration (Cmax) was reached in 6 days in both the 30 and 80 mg groups, with an elimination half-life of 18 days. The Cmax and area under the plasma concentration-time curve increased in a dose-dependent manner, and the trough concentration reached steady state by week 16. The exposure of OZR correlated negatively with patient body weight and was not affected by other patient baseline characteristics. Effects of ADAs on the exposure and efficacy of OZR were limited in both trials. However, antibodies that neutralize the binding to TNFα had some effect on the exposure and efficacy of OZR in the NATSUZORA trial. The receiver operating characteristic analysis of the effect of trough concentration on the American College of Rheumatology 20% and 50% improvement rates was retrospectively performed, and a cutoff trough concentration of approximately 1 μg/mL at week 16 was obtained in both trials. The efficacy indicators in the subgroup with trough concentration ≥ 1 μg/mL were higher than those in the < 1 μg/mL subgroup at week 16, while no clear cutoff was obtained at week 52 in both trials. CONCLUSIONS OZR showed a long half-life and favorable PK properties. A post hoc analysis suggested sustained efficacy independent of trough concentration by subcutaneous administration of OZR 30 mg at 4-week intervals for 52 weeks. TRIAL REGISTRATION JapicCTI, OHZORA trial: JapicCTI-184029, registration date July 9, 2018; NATSUZORA trial: JapicCTI-184031, registration date July 9, 2018.

Abstract
INTRODUCTION The introduction of biologic therapies and a treat-to-target approach has transformed the management of rheumatoid arthritis (RA), which has led to improved outcomes for women with RA who wish to become pregnant. However, guidelines for the management of reproductive health in female patients with RA are still lacking. AREAS COVERED A task force (Women of Childbearing Age [WoCBA]-Rheumatoid Arthritis in Japan) comprising 10 experts in the fields of rheumatology, obstetrics and orthopedic surgery developed 10 clinical questions (CQ) related to the management of WoCBA with RA. For each CQ, a systematic literature review was conducted to identify relevant evidence. Based on this evidence, a set of recommendations for each CQ were drafted and evaluated using the modified Delphi method. This article describes the agreed recommendations along with the supporting evidence. EXPERT OPINION There are many ongoing challenges associated with the provision of reproductive healthcare in WoCBA with RA. It is hoped that the consensus-based recommendations provided here can be implemented in clinical practice in order to increase collaboration between rheumatologists and obstetricians/gynecologists and to improve reproductive health outcomes for WoCBA with RA.
