Patients with High Baseline Neutrophil-to-Lymphocyte Ratio Exhibit Better Response to Filgotinib as Treatment for Rheumatoid Arthritis.

High baseline neutrophil-to-lymphocyte ratio (NLR) in rheumatoid arthritis (RA) has been associated with positive responses to biologic tumor necrosis factor inhibition and negative responses to conventional synthetic disease-modifying antirheumatic drug (csDMARD) triple therapy. Datasets from three randomized clinical trials in patients with RA were used to test the hypothesis that baseline NLR is associated with improved clinical response to filgotinib in methotrexate (MTX)-naïve or MTX-experienced RA populations. Patients from FINCH 1 (inadequate response to MTX, MTX-IR; NCT02889796), FINCH 2 (inadequate response to biologic DMARDs; NCT02873936), and FINCH 3 (MTX-naïve; NCT02886728) were classified as baseline NLR-High or baseline NLR-Low based on a previously published cut point of 2.7. In total, 3365 patients were included across the three studies. Differences in clinical outcomes and patient-reported outcomes (PROs) were determined using linear-regression models. Control-arm patients (placebo + MTX/placebo + csDMARD) classified as NLR-High exhibited worse continuous clinical and PRO responses at week 12 across clinical trials compared to NLR-Low patients. In contrast, NLR-High patients who received FIL 200mg + MTX/csDMARD exhibited consistently better responses after 12weeks compared to NLR-Low patients across clinical trials, clinical endpoints, and PROs. These trends were most prominent among the MTX-IR population. The 2.7 baseline NLR cut point could be used to enrich for patients most likely to benefit from the addition of filgotinib to background MTX/csDMARD. Use of baseline NLR as part of therapeutic decision-making would not require additional diagnostics and could contribute to improved outcomes for patients with RA.

Vaccination Rates and Influencing Factors in Patients with Axial Spondyloarthritis and Immunosuppressive Treatment-A Survey-Based Cross-Sectional Study.

Patients with axial spondyloarthritis (axSpA) who receive immunosuppressive therapy are at risk of infection due to impaired immune function and immunosuppressive medication. Vaccination plays a crucial role in preventing infections in this population. However, vaccination rates and factors influencing vaccination uptake in axSpA patients still need to be adequately studied. This study was designed to determine the vaccination rates of vaccines covered by health insurance in this particular group in Turkey and attitudes towards vaccines and infections. This survey included 199 patients with axSpA who visited our outpatient clinic in June, July, and August 2023 and received biologic and targeted synthetic disease-modifying antirheumatic drugs. The mean age of the participants was 43.7 ± 0.7 years, and the majority were male (66.3%). The majority of the patients were vaccinated against COVID-19 (85.4%), followed by hepatitis B (41.2%), influenza (20.1%), and pneumococcal pneumonia (10.5%). While awareness of COVID-19 vaccination was widespread (100%), knowledge of other vaccines was lower (hepatitis B 80.9%, influenza 70.3%, pneumococcal 60.3%, respectively). Educational interventions targeting patients and healthcare professionals are needed to improve vaccination rates in this population. Our findings emphasize the need for strategies to increase vaccination rates in axSpA patients receiving immunosuppressive therapy. Removing barriers to vaccination and raising awareness of the importance of vaccination are critical to optimizing vaccination practices in this vulnerable population.

A Canadian Retrospective Chart Review Evaluating Concomitant Methotrexate De-escalation Patterns in Patients with Rheumatoid Arthritis Treated with Biologic or Targeted Synthetic DMARDs.

Rheumatoid arthritis (RA) guidelines recommend methotrexate (MTX)-anchored therapy with biologic or targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs); however, tolerability issues often lead to non-adherence. Canadian data on MTX tapering and/or withdrawal following b/tsDMARD initiation are minimal. This chart review assessed frequency of MTX tapering or withdrawal following b/tsDMARD initiation and the impact on disease status in Canadian adults with RA. Eligible patients had received MTX for ≥ 3months before b/tsDMARD initiation. The b/tsDMARD was prescribed continuously for ≥ 18months. Patients taking > 10mg/day oral prednisone or equivalent were excluded. Eight hundred eighty-nine patients (mean baseline MTX dose 19.0mg/week) prescribed b/tsDMARDs (tumor necrosis factor inhibitor 52.1%, Janus kinase inhibitor 18.3%, interleukin-6 inhibitor [IL-6i] 11.9%, other 17.7%) were evaluated at 22 Canadian centers. Within 2years of b/tsDMARD initiation, MTX was tapered in 123 (13.8%) patients and discontinued in 147 (16.5%), most commonly due to planned tapering (36.6%) and patient decision (27.2%), respectively, and most commonly with IL-6i use (34.9%). The MTX dose was unchanged for 582 (65.5%) patients and increased for 37 (4.2%). Missing data limit interpretations of MTX dose effects on some secondary endpoints and challenge the assertion that a disease activity measure-based treat-to-target approach is routinely used in Canadian rheumatology practice. Methotrexate tapering or withdrawal occurred in 30.4% of Canadians with RA within 2years following b/tsDMARD initiation. Baseline disease activity measures were missing from many medical records. However, for patients with baseline assessments, MTX tapering or discontinuation did not worsen disease activity.

Gender Differences in Perceptions of Psoriatic Arthritis Disease Impact, Management, and Physician Interactions: Results from a Global Patient Survey.

We evaluated the impact of gender on disease severity, health-related quality of life (HRQoL), treatment management, and patient-healthcare professional (HCP) interactions from the perspectives of patients with psoriatic arthritis (PsA). Data were collected from a global online patient survey conducted by The Harris Poll (November 2, 2017 to March 12, 2018). Eligible patients were aged ≥ 18years, with a self-reported diagnosis of PsA for > 1year, had visited a rheumatologist/dermatologist in the past 12months, and had reported previously using ≥ 1 conventional synthetic or biologic disease-modifying antirheumatic drug. Data were stratified by gender and analyzed descriptively, inferentially by binomial (chi-square) tests, and by multivariate logistic regression models. Data from 1286 patients who participated were included: 52% were female, 48% were male. Varying perceptions of disease severity between males and females were indicated by differences in symptoms leading to a diagnosis of PsA, and in symptoms reported despite treatment; more females than males reported joint tenderness, skin patches/plaques, and enthesitis. More females than males reported a major/moderate impact of PsA on their physical activity and emotional/mental well-being. Reasons for switching medication differed between genders, with more females switching because they perceived their medication to not be effective enough related to their joint symptoms. More females than males were very satisfied with their communication with their rheumatologist and were more likely to discuss the impact of PsA on their daily lives, their treatment satisfaction, and treatment goals with their rheumatologist. Patients' perceptions of the impact of PsA on HRQoL, treatment management, and interactions with HCPs varied between males and females. More females than males reported major/moderate physical and emotional impacts of PsA. When treating patients, it is important for HCPs to consider the potential impact of gender on patients' experience of PsA and its symptoms.

Retention Rate of Ixekizumab in Psoriatic Arthritis: A Real-World Study.

We aimed to examine the drug retention rate (DRR) of the interleukin-17 inhibitor ixekizumab in a real-world monocentric cohort of psoriatic arthritis (PsA) patients and to assess the predictors of drug discontinuation. Consecutive PsA patients who underwent treatment with ixekizumab from October 2019 to February 2023 were enrolled in this observational, retrospective, monocentric study. Clinical records were assessed at baseline and throughout the follow-up period. We collected sociodemographic data, smoking habits, body mass index, the presence of Human Leukocyte Antigen B27, comorbidities, disease involvement and duration, previous therapy, discontinuation of ixekizumab, reasons for discontinuation, and adverse events (AEs). DRR was evaluated as time to drug discontinuation and assessed through Kaplan-Meier curves. Baseline factors predicting drug discontinuation were investigated through logistic regression models. Eighty PsA patients were included in this study. Ixekizumab was administered at a dose of 160 mg by subcutaneous injection at baseline, followed by 80 mg every four weeks thereafter. Ixekizumab had a 38-month-cumulative DRR of 43.8%, accounting for both inefficacy and AEs. When considering only inefficacy, the DRR was 62.6%. Comorbidities (p = 0.665), obesity (p = 0.665), smoking (p = 0.884), disease duration ≤ 2 years (p = 0.071), axial (p = 0.131) and skin involvement (p = 0.460), and previous therapies, including conventional synthetic (p = 0.504) and biological (p = 0.474) Disease-Modifying Antirheumatic Drugs (bDMARDs), as well as the number of previous bDMARDs or targeted synthetic Disease-Modifying Antirheumatic Drugs (tsDMARDs), did not significantly affect the DRR (p = 0.349). Multivariate analysis found no independent predictors of drug discontinuation. The most frequent AEs leading to discontinuation were skin reactions; no severe infections were observed. In our real-world study, comorbidities, disease duration, and previous therapies did not affect the DRR of ixekizumab. Ixekizumab had a favorable safety profile, with no severe AEs observed.

Effects of IL-6, JAK, TNF inhibitors, and CTLA4-Ig on knee symptoms in patients with rheumatoid arthritis

This study aims to identify factors influencing the alleviation of knee joint symptoms in patients with rheumatoid arthritis treated with biologic or target synthetic disease-modifying antirheumatic drugs (b/tsDMARDs). Among 2321 patients who started b/tsDMARDs between 2010 and 2023, we focused on 295 patients who had knee swelling or tenderness at the initiation of b/tsDMARDs and continued b/tsDMARDs at least 3 months, with recorded knee symptoms 6 months later. Symptom relief after 6 months was 78.2% for interleukin 6 (IL-6) inhibitors, 68.6% for Janus kinase (JAK) inhibitors, 65.8% for tumor necrosis factor (TNF) inhibitors, and 57.6% for cytotoxic T lymphocyte-associated antigen-4-Ig (CTLA4-Ig). The initial use of b/tsDMARDs and the use of IL-6 inhibitors in comparison to CTLA4-Ig emerged as a significant factor associated with the improvement of knee joint symptoms. Among 141 patients who underwent knee radiography at baseline and two years later, the deterioration in knee joint radiographs was 7.7% for IL-6 inhibitors, 6.3% for JAK inhibitors, 21.9% for TNF inhibitors, and 25.9% for CTLA4-Ig. The use of IL-6 inhibitors was a significant factor associated with the improvement of knee joint symptoms and the inhibition of joint destruction compared to CTLA4-Ig.

Pharmacokinetics of Anti-rheumatic Drugs Methotrexate and Tofacitinib with its Metabolite M9 in Rats by UPLC-MS/MS.

Tofacitinib is an oral JAK inhibitor for the treatment of rheumatoid arthritis (RA). The clinical efficacy and safety of an administered tofacitinib, either monotherapy or in combination with conventional synthetic disease-modifying anti-rheumatic drugs, mainly methotrexate (MTX), have been evaluated. The high plasma concentration with delayed medicine clearance may affect the liver and/or kidney functions. In this study, an ultra-performance liquid chromatography-tandem mass spectrometry (UPLC- MS/MS) method for the quantitative analysis of methotrexate, tofacitinib, and metabolite M9 in plasma of Sprague Dawley (SD) rats was developed, and its effectiveness was validated as well. Methotrexate, tofacitinib, M9 and fedratinib (internal standard, IS) were separated by gradient elution. The chromatography was performed on an Acquity BEH C18 (2.1 mm × 50 mm, 1.7 μm) column with the mobile phases of acetonitrile and 0.1% formic acid aqueous solution with different proportions at the flow rate of 0.30 mL/min. In the positive ionization mode, the analyzes were detected using a Xevo TQ-S triple quadrupole tandem mass spectrometer, with the following mass transition pairs: m/z 313.12 → 148.97 for tofacitinib, m/z 329.10 → 165.00 for M9 and m/z 455.12 → 308.05 for methotrexate. The obtained results manifested good calibration linearity over the ranges of tofacitinib at 0.1-100 ng/mL, M9 at 0.05-100 ng/mL, and methotrexate at 0.05-100 ng/mL. The lower limit of quantifications (LLOQs) of methotrexate, tofacitinib and M9 were 0.05 ng/mL, 0.1 ng/mL and 0.05 ng/mL, respectively. Intra-day and inter-day accuracy values were confirmed with a range of -6.3% to 12.7%, while intra-day and inter-- day precision values were ≤14.4%. Additionally, recoveries were greater than 86.5% for each compound without significant matrix effects. The currently established analytical method exhibited great potential for the evaluation of plasma concentrations of methotrexate, tofacitinib and M9 simultaneously, greatly reducing the detection time, which would serve as a supplementary role in formulating dose decisions to achieve personalized treatment, identify drugs that cause adverse reactions and finally, to assess drug-drug interactions on clinical studies.

Cost-Utility Analysis of TNF-α Inhibitors, B Cell Inhibitors, and JAK Inhibitors Versus csDMARDs for Rheumatoid Arthritis Treatment.

Rheumatoid arthritis (RA) is a progressive and debilitating disease, causing persistent joint pain that limits daily activities requiring long-term treatment. Newer targeted therapies expand RA treatment options, but their high cost necessitates a focus on cost effectiveness. To address this, we aim to conduct a cost-utility analysis of these newer RA pharmacotherapies to support evidence-based policy decision-making. We analyzed the cost-utility of sequential treatment with TNF-α, B cell and JAK-inhibitors compared with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) for RA treatment in methotrexate (MTX) nonresponders. We used a Markov model with lifetime horizon and 6-month cycles from an Indian health system perspective. Costs (INR 2022) and quality-adjusted life years (QALYs) were used to determine the incremental cost-effectiveness ratios (ICERs) at a cost-effectiveness threshold of India's gross domestic product (GDP) per capita (2022). We assessed uncertainty using univariate, probabilistic sensitivity, and scenario analyses. Despite additional QALYs, TNF-α, B cell, and JAK inhibitors were not cost-effective for treating moderate-to-severe patients with RA unresponsive to csDMARDs (including MTX) in India, as increased costs outweighed their clinical benefits. ICERs ranged from 10,46,206 to 31,09,207Indian Rupees in the base case analysis, exceeding three times India's GDP per-capita [approximately USD $13,287 to $39,487 and GBP £10,776 to £32,025]. Sensitivity analyses confirmed the results' robustness. Scenario analysis suggested that a cost reduction of over 75% in drug prices could make most of the interventions cost effective compared with csDMARDs. TNF-α, B cell, and JAK-inhibitors are not cost-effective compared with csDMARDs for patients with RA who have not responded to MTX in India at the current prices. Cost-effectiveness estimates were highly influenced by drug pricing variations. Therefore, reducing the prices of these interventions could enhance affordability, potentially leading to their inclusion in publicly funded health programs.

Cost-Effectiveness of Biosimilars vs Leflunomide in Patients With Rheumatoid Arthritis

Among patients with rheumatoid arthritis (RA) who had an inadequate response to methotrexate, a treatment sequence initiated with biosimilar disease-modifying antirheumatic drugs (DMARDs) provides better clinical efficacy compared with conventional synthetic DMARDs recommended by current treatment guidelines; but its cost-effectiveness evidence remains unclear. To evaluate the cost-effectiveness of the treatment sequence initiated with biosimilar DMARDs after failure with methotrexate vs leflunomide and inform formulary listing decisions. This economic evaluation's cost-effectiveness analysis was performed at a Hong Kong public institution using the Markov disease transition model to simulate the lifetime disease progression and cost for patients with RA, using monetary value in 2022. Scenario and sensitivity analyses were performed to test the internal validity of the modeling conclusion. Participants included patients diagnosed with RA from 2000 to 2021 who were retrieved retrospectively from local electronic medical records to generate model input parameters. Statistical analysis was performed from January 2023 to March 2024. The model assesses 3 competing treatment sequences initiated with biosimilar infliximab (CT-P13), biosimilar adalimumab (ABP-501), and leflunomide; all used in combination with methotrexate. Lifetime health care cost and quality-adjusted life-years (QALYs) of the simulated cohort. In total, 25 099 patients with RA were identified (mean [SD] age, 56 [17] years; 19 469 [72.7%] women). In the base-case analysis, the lifetime health care cost and QALYs for the treatment sequence initiated with leflunomide were US $154 632 and 14.82 QALYs, respectively; for biosimilar infliximab, they were US $152 326 and 15.35 QALYs, respectively; and for biosimilar adalimumab, they were US $145 419 and 15.55 QALYs, respectively. Both biosimilar sequences presented lower costs and greater QALYs than the leflunomide sequence. In the deterministic sensitivity analysis, the incremental cost-effectiveness ratio (US$/QALY) comparing biosimilar infliximab sequence vs leflunomide sequence and biosimilar adalimumab sequence vs leflunomide sequence ranged from -15 797 to -8615 and -9088 to 10 238, respectively, all below the predefined willingness-to-pay threshold (US $48 555/QALY gain). In the probabilistic sensitivity analysis, the probability of treatment sequence initiated with leflunomide, biosimilar infliximab, and biosmilar adalimumab being cost-effective out of 10 000 iterations was 0%, 9%, and 91%, respectively. In this economic evaluation study, the treatment sequences initiated with biosimilar DMARDs were cost-effective compared with the treatment sequence initiated with leflunomide in managing patients with RA who experienced failure with the initial methotrexate treatment. These results suggest the need to update clinical treatment guidelines for initiating biosimilars immediately after the failure of methotrexate for patients with RA.

Elevated Serum Levels of YKL-40, YKL-39, and SI-CLP in Patients with Treatment Failure to DMARDs in Patients with Rheumatoid Arthritis.

Around 30-60% of patients with rheumatoid arthritis (RA) present treatment failure to conventional synthetic disease-modifying antirheumatic drugs (csDMARDs). Chitinase-like proteins (CLPs) (YKL-40, YKL-39, SI-CLP) might play a role, as they are associated with the inflammatory process. This study aimed to evaluate CLP utility as a biomarker in the treatment failure of csDMARDs. A case-control study included 175 RA patients classified into two groups based on therapeutic response according to DAS28-ESR: responders (DAS28 < 3.2); non-responders (DAS28 ≥ 3.2). CLP serum levels were determined by ELISA. Multivariable logistic regression and receiver operating characteristic (ROC) curves were used to evaluate CLPs' utility as biomarkers of treatment failure. Non-responders presented higher levels of YKL-40, YKL-39, and SI-CLP compared with responders (all: p < 0.001). YKL-40 correlated positively with YKL-39 (rho = 0.39, p < 0.001) and SI-CLP (rho = 0.23, p = 0.011) and YKL-39 with SI-CLP (rho = 0.34, p < 0.001). The addition of CLPs to the regression models improves diagnostic accuracy (AUC 0.918) compared to models including only clinical classical variables (AUC 0.806) p < 0.001. Non-responders were positive for all CLPs in 35.86%. Conclusions: CLPs could be considered as a useful biomarker to assess treatment failure, due to their association with clinical variables and improvement to the performance of regression models.

Some features of osteogenesis in ankylosing spondylitis and the possibilities of treatment with bisphosphonates

Despite the high efficacy of currently available targeted synthetic disease-modifying antirheumatic drugs (tsDMARDs) and biologic DMARDs (bDMARDs), approximately 40 % of patients with ankylosing spondylitis (AS) fail to achieve treatment goals according to clinical, laboratory and imaging tests. In addition, comorbidities in AS, which require an integrated approach involving different specialists, may limit the use of such therapy. In view of the above, as well as the peculiarities of bone metabolism in AS, new therapeutic approaches for this disease have recently been sought, one of which is the use of bisphosphonates. This article discusses some aspects of bone metabolism and unconventional therapeutic options – the use of bisphosphonates in AS complicated by severe comorbidities, in patients with insufficient efficacy of bDMARDs and/or DMARDs.

Secondary fibromyalgia in children with immune-inflammatory rheumatic diseases

Patients with immune-inflammatory rheumatic diseases (IIRDs) often present with non-inflammatory musculoskeletal pain associated with nociceptive dysfunction, central sensitization, and secondary fibromyalgia (FM). In recent years, an increasing number of publications have appeared dealing with FM in rheumatoid arthritis and systemic connective tissue diseases in adult patients, while this problem is little discussed in pediatric rheumatology, partly due to the differences between the existing diagnostic criteria in children and adults, which complicate the diagnosis of juvenile secondary FM. The consequence of this is often the unfounded prescription or switching of synthetic disease-modifying antirheumatic drugs (DMARDs) or biologic DMARDs in patients who do not require intensified antirheumatic therapy, but rather psychotherapy and psychopharmacotherapy, as well as the wider use of physical and rehabilitation medicine methods. In a brief narrative review, we tried to trace the investigation of FM in a rheumatological clinic, including children with IIRD, from a historical perspective, to summarize current literature data on this problem and to point out possible solutions.

Results of a 24-week open-label, non-interventional study on the efficacy and safety of olokizumab therapy in patients with rheumatoid arthritis after switching from anti-B-cell therapy during the SARS-CoV-2 pandemic

In the context of the new coronavirus infection (NCI) COVID-19 pandemic, the rheumatological community is facing new challenges in the treatment of immune-inflammatory rheumatic diseases (IIRDs). It has been shown that rheumatological patients have an increased risk of infections and a severe course of NCI and that IIRD therapy also influences the disease outcomes. In particular, the use of the anti-B-cell medication rituximab (RTM) is associated with a higher risk of severe NCI and increased mortality. The COVID-19 pandemic has highlighted the need to find alternative and safe treatment options for these patients. This work is the continuation of a 12-week study on the efficacy and safety of olok-izumab (OKZ) therapy in patients with rheumatoid arthritis (RA) after switching from anti-B-cell therapy during the SARS-CoV-2 pandemic. Objective: to evaluate the efficacy and safety of OKZ (Artlegia®; solution for subcutaneous administration, 160 mg/ml – 0.4 ml) for the treatment of patients with RA in real-life clinical practice after switching from RTM during the COVID-19 pandemic. Material and methods. The study included 19 patients with a confirmed diagnosis of RA who had received RTM at a dose of 500–1000 mg twice every 14 days at least 6 months ago. As disease activity increased, RTM was replaced with OKZ while therapy with synthetic disease-modifying anti-rheumatic drugs (DMARDs) was continued. At weeks 0, 4, 8, 12 and 24 after switching the biologic DMARD, the number of tender (TJN) and swollen (SJN) joints out of 28, pain intensity on a visual analogue scale, ESR, CRP level, disease activity indices CDAI, DAS28-ESR, DAS28-CRP, HAQ index and the safety profile of the therapy were assessed at each visit. Results and discussion. After 4, 8, 12 and 24 weeks of OKZ administration, there was a statistically significant decrease in mean TJN (from 10 to 6.0, 3.0, 5.0 and 4.0, respectively; p &lt; 0.05) and SJN (from 7.0 to 3.0 by week 4 and to 2.0 by weeks 8, 12 and 24; p &lt; 0.05). At the same time, a decrease in CRP and ESR values was also observed: median CRP decreased from 18 to 0.6 mg/l by week 4 and to 0.5 mg/l by weeks 8, 12 and 24 (p &lt; 0.05), ESR from 30 to 5 mm/h in each study period (p &lt; 0.05). CRP levels normalized by week 4, regardless of baseline values. All RA activity indices showed a positive dynamic compared to baseline values from week 4 onwards in each assessment period. After weeks 4, 8, 12 and 24, the median DAS28-ESR decreased from 5.50 to 3.57; 3.30; 3.08 and 3.01 (p &lt; 0.05); DAS28-CRP – from 5.30 to 3.46; 3.23; 3.26 and 3.12 (p &lt; 0.05); CDAI – from 27.0 to 17.0; 12.0; 15.0 and 12.0 (p &lt; 0.05), respectively. All patients showed a decrease in pain by the 4th week of observation. A statistically significant improvement in functional status was observed after the 4th week of therapy and was maintained until week 24. The median HAQ index decreased from 1.62 to 1.50 at weeks 4, 8 and 12 and to 1.12 at week 24 (p &lt; 0.05). Conclusion. The study showed that the non-medical switch from RTM to OKZ during the COVID-19 pandemic was effective and safe.

Comparative Efficacy of Advanced Therapies in the Treatment of Radiographic Axial Spondyloarthritis or Ankylosing Spondylitis as Evaluated by the ASDAS Low Disease Activity Criteria.

With an increasing number of biologic/targeted synthetic disease-modifying antirheumatic drug options available for the treatment of active ankylosing spondylitis (AS), also known as radiographic axial spondyloarthritis, it is of clinical interest to determine the comparative efficacy of these advanced therapies among populations with differing prior advanced therapy exposure. This study aimed to assess the comparative efficacy of approved advanced therapies for AS in tumor necrosis factor inhibitor (TNFi)-naïve and, separately, in TNFi inadequate responder/intolerant (-IR) populations. A systematic literature review was conducted to identify randomized clinical trials for TNFis, interleukin-17A inhibitors, and Janus kinase inhibitors used as advanced therapies for active AS. Clinical efficacy was considered by the Ankylosing Spondylitis Disease Activity Score low disease activity (ASDAS LDA) criteria, defined as ASDAS score less than 2.1, among approved therapies. Comparative efficacy in the TNFi-naïve population was assessed utilizing network meta-analysis, while comparative efficacy in the TNFi-IR population was assessed utilizing matching-adjusted indirect comparison. Odds ratios were calculated, from which absolute rates and numbers needed to treat were calculated. Safety in the form of trial-reported and placebo-adjusted rates of discontinuation due to adverse events (AEs) was reviewed. Among the TNFi-naïve population, the estimated ASDAS LDA rate between week12 and 16 was highest for patients treated with upadacitinib (52.8%) and lowest for patients treated with placebo (11.6%). Among the TNFi-IR population, the estimated ASDAS LDA rate was 41.3% for patients treated with upadacitinib and 17.5% for patients treated with ixekizumab. The trial-reported and placebo-adjusted rates of discontinuation due to AEs were generally low across included advanced therapies. Relative to other assessed therapies, upadacitinib demonstrated greater clinical efficacy per ASDAS LDA in the treatment of active AS in both TNFi-naïve and TNFi-IR populations. Head-to-head and real-world data comparisons are warranted to both validate these findings and aid medical decision makers.

The prescription and monitoring of conventional synthetic disease-modifying anti-rheumatic drugs: British Society for Rheumatology guideline scope.

This guideline will provide up-to-date, evidence-based recommendations on the safe use of non-biologic DMARDs, also called conventional synthetic DMARDs (csDMARD), across the full spectrum of autoimmune rheumatic diseases. The guideline will update the guideline published in 2017 and will be expanded to include people of all ages. Updated information on the monitoring of DMARDs and vaccinations will be included. The guideline will be developed using the methods and processes described in the British Society for Rheumatology's 'Creating clinical guidelines: our protocol', updated 2023.

Bimekizumab (Bimzelx)

CADTH recommends that Bimzelx be reimbursed by public drug plans for the treatment of active psoriatic arthritis (PsA) if certain conditions are met. Bimzelx should only be covered to treat adult patients with active PsA according to the reimbursement criteria used for other biologic disease-modifying antirheumatic drugs (bDMARDs) that are currently reimbursed by public drug plans. Bimzelx should only be reimbursed if it is prescribed by a rheumatologist or a clinician who has experience treating adult patients with active PsA and if it does not cost more than the least expensive bDMARD reimbursed for the treatment of active PsA. Bimzelx should not be reimbursed when used together with other biologic or targeted synthetic disease-modifying antirheumatic drugs (tsDMARDs) for active PsA.
