Abstract
Subcutaneous (SC) injections can be associated with local pain and discomfort that is subjective and may affect treatment adherence and overall patient experience. With innovations increasingly focused on finding ways to deliver higher doses and volumes (≥2 mL), there is a need to better understand the multiple intertwined factors that influence pain upon SC injection. As a priority for the SC Drug Development & Delivery Consortium, this manuscript provides a comprehensive review of known attributes from published literature that contribute to pain/discomfort upon SC injection from three perspectives: (1) device and delivery factors that cause physical pain, (2) formulation factors that trigger pain responses, and (3) human factors impacting pain perception. Leveraging the Consortium's collective expertise, we provide an assessment of the comparative and interdependent factors likely to impact SC injection pain. In addition, we offer expert insights and future perspectives to fill identified gaps in knowledge to help advance the development of patient-centric and well tolerated high-dose/high-volume SC drug delivery solutions.

Safety and effectiveness of certolizumab pegol in Japanese patients with rheumatoid arthritis: Up to 3-year results from a postmarketing surveillance study. Mod Rheumatol 2024:roae019. [PMID: 38619380 DOI: 10.1093/mr/roae019] [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: 08/28/2023] [Accepted: 02/22/2024] [Indexed: 04/16/2024]
Abstract
OBJECTIVES To report up to 3-year safety and effectiveness of certolizumab pegol (CZP) in Japanese patients with rheumatoid arthritis from a postmarketing surveillance study. METHODS Patients enrolled previously completed 24 weeks of CZP in the 24-week postmarketing surveillance study. Adverse drug reactions (ADRs) were recorded for patients who received ≥1 CZP dose. Effectiveness outcomes were 28-joint Disease Activity Score with erythrocyte sedimentation rate and European Alliance of Associations for Rheumatology response. Week 24-156 safety and Week 0-52 effectiveness data are reported here. RESULTS A total of 781 patients were enrolled, with 735 and 376 patients evaluated for safety and effectiveness, respectively. Within the safety set, 17.8% (131/735) of patients reported ADRs; 9.4% (69/735) reported serious ADRs. Among patients with history of respiratory, thoracic, and mediastinal disorders, 38.4% (28/73) reported ADRs. The most frequent ADRs were infections and infestations (11.8%; 87/735); skin and subcutaneous tissue disorders (1.9%; 14/735); respiratory, thoracic, and mediastinal disorders (1.6%; 12/735). Mean 28-joint Disease Activity Score with erythrocyte sedimentation rate reduced from 4.6 (Week 0) to 2.8 (Week 52). At Week 52, 51.8% (161/311) of patients achieved European Alliance of Associations for Rheumatology Good response. CONCLUSIONS The long-term safety and effectiveness of CZP in the real-world setting in Japan were consistent with previously reported data; no new safety signals were identified.

Remission definitions guiding immunosuppressive therapy in rheumatoid arthritis: which is best fitted for the purpose? RMD Open 2024; 10:e003972. [PMID: 38443090 DOI: 10.1136/rmdopen-2023-003972] [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: 12/04/2023] [Accepted: 02/16/2024] [Indexed: 03/07/2024] Open
Abstract
OBJECTIVE To assess which definition of remission best predicts good radiographic outcome (GRO) and good functional outcome (GFO) in rheumatoid arthritis, focusing the updated American College of Rheumatology/European Alliance of Associations for Rheumatology criteria. MATERIAL AND METHODS Meta-analyses of individual patient data (IPD) from randomised controlled trials (RCTs). Six definitions of remission were considered: (1) Boolean with Patient Global Assessment (PGA)≤1 (Boolean); (2) Simplified Disease Activity Index (SDAI)≤3.3; (3) Clinical Disease Activity Index (CDAI)≤2.8; (4) Boolean with PGA≤2 (Updated-Boolean); (5) Boolean with Physician Global Assessment (PhGA≤1) replacing PGA (Boolean-PhGA) and (6) Boolean excluding PGA (3VBoolean). GRO was defined as a worsening ≤0.5 units in radiographic score and GFO as a no worsening in Health Assessment Questionnaire (HAQ), that is, ∆HAQ-DI≤0.0 units. Relationships between each remission definition at 6 and/or 12 months and GRO and GFO during the second year were analysed. Pooled probabilities for each outcome for each definition and their predictive accuracy were estimated. RESULTS IPD from eight RCTs (n=4423) were analysed. Boolean, SDAI, CDAI, Updated-Boolean, Boolean-PhGA and 3VBoolean were achieved by 24%, 27%, 28%, 32%, 33% and 43% of all patients, respectively. GRO among patients achieving remission ranged from 82.4% (3VBoolean) to 83.9% (SDAI). 3VBoolean showed the highest predictive accuracy for GRO: 51.1% versus 38.8% (Boolean) and 44.1% (Updated-Boolean). The relative risk of GFO ranged from 1.16 (Boolean) to 1.05 (3VBoolean). However, the proportion of GFO correctly predicted was highest for the 3VBoolean (50.3%) and lowest for the Boolean (43.8%). CONCLUSION 3VBoolean definition provided the most accurate prediction of GRO and GFO, avoiding the risk of overtreatment in a substantial proportion of patients without increment in radiographic damage progression, supporting the proposal that 3VBoolean remission is preferable to guide immunosuppressive treatment. The patient's perspective, which must remain central, is best served by an additional patient-oriented target: a dual-target approach.

Abstract
We report a case of a woman in her 30s with a history of cholecystectomy, hypertension, type 2 diabetes and rheumatoid arthritis on methotrexate and certolizumab who presented with epigastric pain radiating to the right upper quadrant. Laboratory findings revealed significantly elevated liver enzymes consistent with hepatocellular liver injury. The hepatocellular pattern of liver injury, negative autoimmune serologies and improvement on cessation of certolizumab were consistent with drug-induced hepatotoxicity. We used Roussel Uclaf Causality Assessment Method to assess the likelihood of drug-induced liver injury that showed a score of 7, this was in line with a probable causality grading. Although the patient had a history of methotrexate use, the onset of symptoms and transaminitis coincided with the recent initiation of certolizumab, which was the trigger of hepatocellular injury. Liver enzymes also remained normal after the reinitiation of methotrexate on follow-up.

Abstract
OBJECTIVES This study evaluated the prevalence of fibromyalgia (FM), anxiety and depression in patients with rheumatoid arthritis (RA) and their effects on the clinical parameters of RA during the COVID-19 pandemic. DESIGN Cross-sectional, outpatient clinic, observational, non-interventional. SETTING Single-centre, tertiary care, multispecialty, service and research hospital, north-central India. PARTICIPANTS Adult patients with RA, controls. RESULTS This cross-sectional study included 200 patients with RA diagnosed with the American College of Rheumatology/European League Against Rheumatism 2010 (ACR) criteria and 200 controls. FM was diagnosed using the revised 2016 ACR FM Criteria. Disease activity, quality of life and functional disability in patients with RA were assessed using multiple Disease Activity Scores. The presence of depression and anxiety was determined using the Hospital Anxiety and Depression Scale. FM was present in 31% of patients with RA compared with 4% of controls in our study. Patients with RA with FM were older, predominantly females with longer disease duration, and more likely to be on steroids. Patients with RA with FM had a higher disease activity, and none of our RA with FM patients were in remission. The multivariable analysis found FM to be an independent predictor of the Simplified Disease Activity Index for RA. Patients with RA with FM had worse functional ability and poorer quality of life. The prevalence of anxiety and depression was 12.5% and 30%, significantly higher in RA with FM patients. CONCLUSION During the COVID-19 pandemic, around one-third of our study patients had FM and depression, significantly higher than pre-COVID-19 times. Thus, mental health assessment should be incorporated into the routine management of patients with RA.

Abstract
OBJECTIVES We aimed to demonstrate that the proportion of rheumatoid arthritis patients achieving 20%/50%/70% improvement in American College of Rheumatology (ACR20/50/70) responses to Food and Drug Administration-approved biologic disease-modifying antirheumatic drugs (bDMARDs) after an inadequate response to methotrexate (MTX) and after failure of the first bDMARDs followed a consistent pattern. METHODS This systematic review and meta-analysis was performed in accordance with MECIR (Methodological Expectations for Cochrane Intervention Reviews) standards. Two separate groups of randomized controlled trials were included: the first group included studies with biologic-naive patients who added bDMARD to MTX as intervention arm compared with the placebo plus MTX group. The second group included biologic-irresponsive (IR) patients who used a second bDMARD plus MTX after the first bDMARD failure compared with placebo plus MTX group. Primary outcome was defined as the proportion of rheumatoid arthritis patients achieving ACR20/50/70 responses at 24 ± 6 weeks. RESULTS Twenty-one studies initiated between 1999 and 2017 were included: 15 studies for the biologic-naive group and 6 studies for the biologic-IR group. For the biologic-naive group, the proportions of patients achieving ACR20/50/70 were 61.4% (95% confidence interval [CI], 58.7%-64.1%), 37.8% (95% CI, 34.8%-40.8%), and 18.8% (95% CI, 16.1%-21.4%), respectively. For the biologic-IR group, proportions of patients achieving ACR20/50/70 were 48.5% (95% CI, 42.2%-54.8%), 27.3% (95% CI, 21.6%-33.0%), and 12.9% (95% CI, 11.3%-14.8%), respectively. CONCLUSION We were able to systematically demonstrate that ACR20/50/70 responses to biologic-naive follow a consistent pattern of 60%, 40%, and 20%, respectively. We also demonstrated that the ACR20/50/70 responses to a biologic IR follow a certain pattern of 50%, 25%, and 12.5%, respectively.

Abstract
INTRODUCTION There is a paucity of data on how patient characteristics may affect the long-term durability of certolizumab pegol (CZP) in patients with rheumatoid arthritis (RA). This study therefore aimed to investigate CZP durability and reasons for discontinuation over 5 years between different subgroups of patients with RA. METHODS Data were pooled from 27 clinical trials in RA patients. Durability was defined as the percentage of patients randomized to CZP at baseline who were still on CZP treatment at a given timepoint. Post hoc analyses of clinical trial data on CZP durability and reasons for discontinuation among different patient subgroups were conducted using Kaplan-Meier curves and Cox proportional hazards modeling. Patient subgroups included: age (18- < 45/45- < 65/ ≥ 65 years), gender (male/female), prior tumor necrosis factor inhibitor (TNFi) use (yes/no), and disease duration (< 1/1- < 5/5- < 10/ ≥ 10 years). RESULTS Among 6927 patients, the durability of CZP was 39.7% at 5 years. Patients aged ≥ 65 years had a 33% greater risk of CZP discontinuation than patients 18- < 45 years (hazard ratio [95% confidence interval]: 1.33 [1.19-1.49]) and patients with prior TNFi use had a 24% greater risk of discontinuing CZP than patients without (1.24 [1.12-1.37]). Conversely, greater durability was observed among patients who had a baseline disease duration of ≥ 1 year. Durability did not differ in the gender subgroup. Of the 6927 patients, the most common reason for discontinuation was inadequate levels of efficacy (13.5%); followed by adverse events (11.9%); consent withdrawn (6.7%); lost to follow-up (1.8%); protocol violation (1.7%); other reasons (9.3%). CONCLUSIONS CZP durability was comparable with durability data on other bDMARDs in RA patients. Patient characteristics that were associated with greater durability included younger age, TNFi-naïvety, and disease duration ≥ 1 year. Findings may be helpful in informing clinicians on a patient's likelihood of discontinuing CZP, based on their baseline characteristics.

Abstract
Tumor necrosis factor (TNF)-α is a potent trimeric cytokine which plays a fundamental role in the host immuno-inflammatory response, as well as in homeostasis and development. Although critical for canonical immune function, TNF-α has great destructive potential and is implicated in the development of multiple immune-mediated disorders. Within the context of rheumatoid arthritis (RA), TNF-α acts as a primary pathogenic driver by precipitating a pro-inflammatory cytokine cascade and coordinating the attraction and activation of immune cells, all of which culminate in damage to the synovium. The discovery of the paramount role of TNF-α in the pathophysiology of RA motivated studies to understand the effects of TNF blockade in vitro and in vivo. Promising preclinical results provided the impetus for clinical trials, spearheaded in the 1980s and 90s by Marc Feldmann, which revealed significant improvements across RA symptom scores and finally led to FDA approval in 1998. As of 2021, five TNF-α blocking agents have been widely applied clinically, including infliximab (IFX), etanercept (ETN), adalimumab (ADA), golimumab (GLM) and certolizumab pegol (CZP). All of them successfully ameliorated symptoms of RA and the associated tissue damage, especially in patients not responding to traditional treatment methods. Anti-TNFs are most often administered in combination with methotrexate (MTX) as part of Phase II treatment (i.e., second line). Although the general availability of anti-TNFs has dramatically improved patient outcomes, sustained remission is rare and the mechanism of RA remains incompletely understood. Thus, additional basic and translational research is warranted, towards the aim of developing novel RA treatments.

Abstract
BACKGROUND AND AIMS Extra-intestinal manifestations are frequently reported in inflammatory bowel diseases. However, data comparing the effect of vedolizumab and ustekinumab on articular extra-intestinal manifestations are limited. The aim here was to evaluate differences in new-onset and the evolution of pre-existing joint extra-intestinal manifestations during both treatments. METHODS An international multicentre retrospective study was performed on inflammatory bowel disease patients who started vedolizumab or ustekinumab between May 2010 and December 2020. Extra-intestinal manifestations were assessed at baseline and joint extra-intestinal manifestations were evaluated throughout the 2-year follow-up. Arthropathy was defined by joint inflammation [arthritis/sacroiliitis], diagnosed by a rheumatologist, and arthralgia as articular pain without confirmed inflammation. Additionally, skin, ocular and hepatic extra-intestinal manifestations were assessed at baseline. Uni- and multivariate analyses were performed. RESULTS In total, 911 patients [vedolizumab: 584; ustekinumab: 327] were included. Deterioration of pre-existing arthropathy and rate of new-onset arthropathy were not significantly associated with vedolizumab over ustekinumab. Arthropathy was used as reason to stop treatment in six vedolizumab and two ustekinumab patients. The odds of developing new arthralgia within 6 months was higher in patients who took vedolizumab compared to ustekinumab (adjusted odds ratio [aOR]: 2.28 [1.01-5.15], p = 0.047). However, this effect was not sustained during the 2-year follow-up (aOR: 1.35 [0.80-2.29], p = 0.259). Deterioration of pre-existing arthralgia was comparable between ustekinumab and vedolizumab-treated patients. In two vedolizumab-treated patients arthralgia was given as the reason to stop treatment. CONCLUSIONS Vedolizumab and ustekinumab can be used safely in patients with articular extra-intestinal manifestations. Only a temporary increased risk for developing arthralgia has been observed under vedolizumab.

Abstract
Biologic drugs have greatly improved treatment outcomes of inflammatory joint diseases, but a substantial proportion of patients either do not respond to treatment or lose response over time. Drug immunogenicity, manifested as the formation of anti-drug antibodies (ADAb), constitute a significant clinical problem. Anti-drug antibodies influence the pharmacokinetics of the drug, are associated with reduced clinical efficacy, and an increased risk of adverse events such as infusion reactions. The prevalence of ADAb differs among drugs and diseases, and the detection of ADAb also depends on the assay format. Most data exist for the tumor necrosis factor-alpha inhibitors infliximab and adalimumab, with a frequency of ADAb that ranges from 10 to 60% across studies. Measurement of ADAb and serum drug concentrations, therapeutic drug monitoring, has been suggested as a strategy to optimize therapy with biologic drugs. Although the recent randomized clinical Norwegian Drug Monitoring (NOR-DRUM) trials show promise towards a personalized medicine prescribing approach by therapeutic drug monitoring, several challenges remain. A plethora of assay formats, with widely differing properties, is currently used for measuring ADAb. Comparing results between different assays and laboratories is difficult, which complicates the development of cut-offs necessary for guidelines and the implementation of ADAb measurements in clinical practice. With the possible exception of infliximab, limited data on clinical relevance and cost effectiveness exist to support therapeutic drug monitoring as a routine clinical strategy to monitor biologic drugs in inflammatory joint diseases. The aim of this review is to provide an overview of the characteristics and prevalence of ADAb, predisposing factors to ADAb formation, commonly used assessment methods, clinical consequences of ADAb, and the potential implications of ADAb assessments for everyday treatment of inflammatory joint diseases.

Abstract
BACKGROUND The aim of this study was to perform a meta-analysis to compare the risk of all-cause mortality between biological/targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) and non-b/tsDMARDs involving patients with rheumatoid arthritis (RA). METHODS We performed a systematic review of articles published up to August 2021 using electronic databases. We included studies that reported all-cause mortality in RA patients and compared b/tsDMARDs and non-b/tsDMARDs. RESULTS We included a total of 77 studies involving 64,428 patients. These comprised 44,227 patients treated with b/tsDMARDs and 20,201 treated with non-b/tsDMARDs. The occurrence of all-cause mortality was the primary outcome. The risk of all-cause mortality between the 2 treatments was not significantly different (relative risk = 1.08; 95% confidence interval = 0.98-1.19). However, subgroup analyses showed significant increase in risks of mortality in anti-TNFs users with RA compared with non-b/tsDMARDs (relative risk = 1.47, 95% confidence interval = 1.02-2.12). No significant differences were found after subgroup analyses based on other molecules involved and study duration. CONCLUSION In comparison with non-b/tsDMARDs, our results suggest that antitumor necrosis factor therapy is associated with observed increased risks of mortality and further investigation is needed.

Abstract
OBJECTIVES To report 24-week safety and effectiveness data of certolizumab pegol (CZP) in Japanese patients with rheumatoid arthritis (RA) from a post-marketing surveillance study. METHODS Enrolled patients were newly receiving CZP. All adverse events (AEs) and adverse drug reactions (ADRs) were recorded for patients who received ≥1 CZP dose. Effectiveness outcomes included: 28-joint Disease Activity Score with erythrocyte sedimentation rate (DAS28-ESR) and EULAR response. Missing data were imputed using last observation carried forward. RESULTS 3,727 patients were enrolled; safety and effectiveness were evaluated in 3,586 and 1,794 patients, respectively. 24.9% of patients reported AEs (n=893/3,586) and 14.7% reported ADRs (528/3,586). Serious AEs and serious ADRs were reported in 8.3% (298/3,586) and 5.3% (190/3,586), respectively. Selected serious ADRs of interest included infections (n=110; 3.1%), tuberculosis (6; 0.2%), interstitial pneumonia (15; 0.4%), malignancy (8; 0.2%) and hepatic function disorder (7; 0.2%). No allergic reactions, autoimmune disease, cardiac failure, demyelinating diseases or pancytopenia were reported. Mean DAS28-ESR reduced from 4.8 (baseline) to 3.4 (final evaluation). At final evaluation, 34.7% of patients achieved EULAR good response. CONCLUSIONS These real-world safety and effectiveness results were consistent with previously reported data, with no new safety signals identified. Long-term, real-world CZP safety and effectiveness data are needed.

Bayesian network meta-analysis methods for combining individual participant data and aggregate data from single arm trials and randomised controlled trials. BMC Med Res Methodol 2022; 22:186.

Abstract
BACKGROUND Increasingly in network meta-analysis (NMA), there is a need to incorporate non-randomised evidence to estimate relative treatment effects, and in particular in cases with limited randomised evidence, sometimes resulting in disconnected networks of treatments. When combining different sources of data, complex NMA methods are required to address issues associated with participant selection bias, incorporating single-arm trials (SATs), and synthesising a mixture of individual participant data (IPD) and aggregate data (AD). We develop NMA methods which synthesise data from SATs and randomised controlled trials (RCTs), using a mixture of IPD and AD, for a dichotomous outcome. METHODS We propose methods under both contrast-based (CB) and arm-based (AB) parametrisations, and extend the methods to allow for both within- and across-trial adjustments for covariate effects. To illustrate the methods, we use an applied example investigating the effectiveness of biologic disease-modifying anti-rheumatic drugs for rheumatoid arthritis (RA). We applied the methods to a dataset obtained from a literature review consisting of 14 RCTs and an artificial dataset consisting of IPD from two SATs and AD from 12 RCTs, where the artificial dataset was created by removing the control arms from the only two trials assessing tocilizumab in the original dataset. RESULTS Without adjustment for covariates, the CB method with independent baseline response parameters (CBunadjInd) underestimated the effectiveness of tocilizumab when applied to the artificial dataset compared to the original dataset, albeit with significant overlap in posterior distributions for treatment effect parameters. The CB method with exchangeable baseline response parameters produced effectiveness estimates in agreement with CBunadjInd, when the predicted baseline response estimates were similar to the observed baseline response. After adjustment for RA duration, there was a reduction in across-trial heterogeneity in baseline response but little change in treatment effect estimates. CONCLUSIONS Our findings suggest incorporating SATs in NMA may be useful in some situations where a treatment is disconnected from a network of comparator treatments, due to a lack of comparative evidence, to estimate relative treatment effects. The reliability of effect estimates based on data from SATs may depend on adjustment for covariate effects, although further research is required to understand this in more detail.

Abstract
Objectives To evaluate the safety of each anti-TNF therapy for patients with rheumatoid arthritis (RA) and then make the best choice in clinical practice. Methods We searched PUBMED, EMBASE, and the Cochrane Library. The deadline for retrieval is August 2021. The ORs, Confidence Intervals (CIs), and p values were calculated by STATA.16.0 software for assessment. Result 72 RCTs involving 28332 subjects were included. AEs were more common with adalimumab combined disease-modifying anti-rheumatic drugs (DMARDs) compared with placebo (OR = 1.60, 95% CI: 1.06, 2.42), DMARDs (1.28, 95% CI: 1.08, 1.52), etanercept combined DMARDs (1.32, 95% CI: 1.03, 1.67); certolizumab combined DMARDs compared with placebo (1.63, 95% CI: 1.07, 2.46), DMARDs (1.30, 95% CI: 1.10, 1.54), etanercept combined DMARDs (1.34, 95% CI: 1.05, 1.70). In SAEs, comparisons between treatments showed adalimumab (0.20, 95% CI: 0.07, 0.59), etanercept combined DMARDs (0.39, 95% CI: 0.15, 0.96), golimumab (0.19, 95% CI: 0.05, 0.77), infliximab (0.15, 95% CI: 0.03,0.71) decreased the risk of SAEs compared with golimumab combined DMARDs. In infections, comparisons between treatments showed adalimumab combined DMARDs (0.59, 95% CI: 0.37, 0.95), etanercept (0.49, 95% CI: 0.28, 0.88), etanercept combined DMARDs (0.56, 95% CI: 0.35, 0.91), golimumab combined DMARDs (0.51, 95% CI: 0.31, 0.83) decreased the risk of infections compared with infliximab combined DMARDs. No evidence indicated that the use of TNF-α inhibitors influenced the risk of serious infections, malignant tumors. Conclusion In conclusion, we regard etanercept monotherapy as the optimal choice for RA patients in clinical practice when the efficacy is similar. Conversely, certolizumab + DMARDs therapy is not recommended. Systematic Review Registration identifier PROSPERO CRD42021276176.

Abstract
Rheumatoid arthritis is a common chronic inflammatory disease with substantial economic, social, and personal costs. Its pathogenesis is multifactorial and complex. The ultimate goal of rheumatoid arthritis treatment is stopping or slowing down the disease progression. In the past two decades, invention of new medicines, especially biologic agents, revolutionized the management of this disease. These agents have been associated with an improved prognosis and clinical remission, especially in patients who did not respond to traditional disease-modifying anti-rheumatic drugs (DMARDs). Improvement in the understanding of the rheumatoid arthritis pathogenesis leads to the development of novel biologic therapeutic approaches. In the present paper, we summarized the current therapeutics, especially biologic agents, available for the treatment of rheumatoid arthritis.

Abstract
The realization of short-term load forecasting is the basis of system planning and decision-making, and it is an important index to evaluate the safety and economy of power grid.In order to accurately predict the power load under the influence of many factors, a new short-term power load prediction method based on fuzzy support vector machine and similar daily linear extrapolation is proposed, which combinesthe method of fuzzy support vector machine and linear extrapolation of similar days. The method first selects similar days according to the effect of integrated weather and time on load. Then the fuzzy membership of the training sample is obtained by the normalization processing, and the daily maximum and minimum load is predicted by the fuzzy support vector machine. Finally, the load prediction value is obtained by combining the load trend curve obtained by the similar daily linear extrapolation method. and this method is feasible and effective for short-term forecasting of power load.

Abstract
BACKGROUND The hand is an excellent work tool that provides the functional ability to mechanical work. The hand is affected in rheumatoid arthritis (RA) patients, it is a significant problem in the functional sphere as a result of deformities, the grasping function limitation and muscle strength. OBJECTIVES The aim of the study was the assessment of grip strength, endurance and manipulation abilities of rheumatoid hands with or without deformities treated with methotrexate (MTX) or MTX plus biologics (MTX+BIO). MATERIAL AND METHODS The study involved 80 RA women, (40 received MTX+BIO, 40 MTX), treated at the Rheumatology Department of the Central Clinical Hospital of Interior Affairs in Warsaw. VAS-pain, DAS28, SDAI, HAQ, HAQ hands, estimation of hand grip strength, endurance, manipulation ability were analyzed. RESULTS In group MTX+BIO values of DAS28 (3.7±1.3 vs 4.3±1.2, p=0.019), HAQ (0.72 ± 0.57 vs 1.08± 0.87, p=0.011) and HAQ-hand (0.85±0.65 vs. 1.19±0.68, p=0.024) were statistically lower than in MTX group. Hand deformations recorded in 35 (43.7%) cases, 16 (40%) in MTX group, 19 (47.5%) in MTX+BIO. Comparison of grip strength, endurance, manipulation ability showed better results in MTX+BIO group with deformities (significance level from 0.013 to 0.046) than in MTX group. Relative differences in hand function in MTX + BIO group ranged from 10.8% (maximal power grip strength) to 127.6% (minimal hand endurance), after disease duration adjustment - from 28.2% (maximal power grip strength) to 148.4% (minimal hand endurance). CONCLUSION Measuring grip strength, hand endurance, manipulation abilities are useful in RA patients with hand deformities.

Abstract
Objective Tofacitinib (TOFA) is an oral, small molecule drug used for rheumatoid arthritis (RA) treatment and is one of several alternative treatments to tumor necrosis factor inhibitors (TNFi). We evaluated physician and patient- reported effectiveness of TNFi compared to TOFA, using real-world data from the Ontario Best Practices Research Initiative (OBRI). Methods Patients enrolled in the OBRI initiating TOFA or TNFi between 2014 and 2019 were included. Patients were required to have physician and patient-reported effectiveness outcomes data available at treatment initiation and 6 months later (± 2 months), which included clinical disease activity index (CDAI) and rheumatoid arthritis disease activity index (RADAI). To deal with confounding by indication, we estimated propensity scores (PS) for covariates. Results 419 patients were included. Of those, 226 initiated a TNFi and 193 TOFA, and had a mean (SD) disease duration of 8.0 (8.7) and 12.6 (9.6) years, respectively. In addition, the TNFi group was less likely to have prior biologic use (21.7%) compared to the TOFA group (67.9%). The proportion of patients in CDAI low disease activity (LDA)/remission at 6 months was 36.7% and 33.2% in the TNFi and TOFA groups, respectively. The generalized linear mixed models (GLMM) adjusting for PS quantile showed that there was no significant difference in CDAI LDA/remission (ORs: 0.85, 95% CI: 0.51, 1.43) and RADAI coefficient (0.48, 95% CI: -0.18, 1.14) between the two groups (Ref: TOFA). Conclusion In patients with RA, physician and patient-reported effectiveness are similar in TNFi and TOFA groups 6 months after treatment.

Abstract
Pegylation of biopharmaceuticals is the most common strategy to increase their half-life in the blood and is associated with a reduced immunogenicity. As antigen presentation is a primary event in the activation of CD4 T-cells and initiation of Anti-Drug Antibody (ADA) response, we investigated the role of the PEG molecule on the T-cell reactivity of certolizumab pegol (CZP), a pegylated anti-TNFα Fab. We generated T-cell lines raised against CZP and its non-pegylated form (CZNP) and demonstrated CZP primed few T-cells in comparison to CZNP. CZP-primed lines from 3 donors responded to a total of 5 epitopes, while CZNP-primed lines from 3 donors responded to a total of 7 epitopes, 4 epitopes were recognized by both CZP- and CZNP-primed lines. In line with this difference of T-cell reactivity, CZP is less internalized by the dendritic cells than CZNP. In vitro digestion assay of CZP by Cathepsin B showed a rapid removal of the PEG moiety, suggesting a limited influence of PEG on CZP proteolysis. We therefore demonstrate that pegylation diminishes antigen capture by dendritic cells, peptide presentation to T-cells and T-cell priming. This mechanism might reduce immunogenicity and contribute to the long half-life of CZP and possibly of other pegylated molecules.

Abstract
Immunosuppressive therapies are currently indicated for a wide range of diseases. As new agents emerge and indications evolve the landscape grows increasingly complex. Therapies can target pathologic immune system over-activation in rheumatologic or autoimmune disease, or conditioning and graft versus host disease (GVHD) prophylactic regimens may eliminate or inhibit host immune function to improve graft survival and risk of complication in solid organ transplantation (SOT) or hematopoietic stem cell transplantation (HSCT). With immunosuppressive therapy, infections occur. Complex disease states, host factors, and concomitant therapies contribute to a "net state" of immunosuppression that must be considered and may confound perceived increased infection risks in patients receiving treatment.

Abstract
Biologics are protein-based pharmaceuticals derived from living organisms or their proteins. We discuss the mechanism of action for currently approved biologics and a give summary of the studies on immune suppression from biologics. Most of these studies have been conducted with rheumatology patients, and many in adults. Their relevance for children is explored and existing gaps in data for children are highlighted.

Abstract
Background
Rheumatoid arthritis is a major inflammatory disorder and causes substantial disability. Treatment goals span minimising disease activity, achieving remission and decreasing disability. In active rheumatoid arthritis, intensive management achieves these goals. As many patients with established rheumatoid arthritis have moderate disease activity, the TITRATE (Treatment Intensities and Targets in Rheumatoid Arthritis ThErapy) programme assessed the benefits of intensive management.

To (1) define how to deliver intensive therapy in moderate established rheumatoid arthritis; (2) establish its clinical effectiveness and cost-effectiveness in a trial; and (3) evaluate evidence supporting intensive management in observational studies and completed trials.
Design
Observational studies, secondary analyses of completed trials and systematic reviews assessed existing evidence about intensive management. Qualitative research, patient workshops and systematic reviews defined how to deliver it. The trial assessed its clinical effectiveness and cost-effectiveness in moderate established rheumatoid arthritis.
Setting
Observational studies (in three London centres) involved 3167 patients. These were supplemented by secondary analyses of three previously completed trials (in centres across all English regions), involving 668 patients. Qualitative studies assessed expectations (nine patients in four London centres) and experiences of intensive management (15 patients in 10 centres across England). The main clinical trial enrolled 335 patients with diverse socioeconomic deprivation and ethnicity (in 39 centres across all English regions).
Participants
Patients with established moderately active rheumatoid arthritis receiving conventional disease-modifying drugs.
Interventions
Intensive management used combinations of conventional disease-modifying drugs, biologics (particularly tumour necrosis factor inhibitors) and depot steroid injections; nurses saw patients monthly, adjusted treatment and provided supportive person-centred psychoeducation. Control patients received standard care.
Main outcome measures
Disease Activity Score for 28 joints based on the erythrocyte sedimentation rate (DAS28-ESR)-categorised patients (active to remission). Remission (DAS28-ESR < 2.60) was the treatment target. Other outcomes included fatigue (measured on a 100-mm visual analogue scale), disability (as measured on the Health Assessment Questionnaire), harms and resource use for economic assessments.
Results
Evaluation of existing evidence for intensive rheumatoid arthritis management showed the following. First, in observational studies, DAS28-ESR scores decreased over 10–20 years, whereas remissions and treatment intensities increased. Second, in systematic reviews of published trials, all intensive management strategies increased remissions. Finally, patients with high disability scores had fewer remissions. Qualitative studies of rheumatoid arthritis patients, workshops and systematic reviews helped develop an intensive management pathway. A 2-day training session for rheumatology practitioners explained its use, including motivational interviewing techniques and patient handbooks. The trial screened 459 patients and randomised 335 patients (168 patients received intensive management and 167 patients received standard care). A total of 303 patients provided 12-month outcome data. Intention-to-treat analysis showed intensive management increased DAS28-ESR 12-month remissions, compared with standard care (32% vs. 18%, odds ratio 2.17, 95% confidence interval 1.28 to 3.68; p = 0.004), and reduced fatigue [mean difference –18, 95% confidence interval –24 to –11 (scale 0–100); p < 0.001]. Disability (as measured on the Health Assessment Questionnaire) decreased when intensive management patients achieved remission (difference –0.40, 95% confidence interval –0.57 to –0.22) and these differences were considered clinically relevant. However, in all intensive management patients reductions in the Health Assessment Questionnaire scores were less marked (difference –0.1, 95% confidence interval –0.2 to 0.0). The numbers of serious adverse events (intensive management n = 15 vs. standard care n = 11) and other adverse events (intensive management n = 114 vs. standard care n = 151) were similar. Economic analysis showed that the base-case incremental cost-effectiveness ratio was £43,972 from NHS and Personal Social Services cost perspectives. The probability of meeting a willingness-to-pay threshold of £30,000 was 17%. The incremental cost-effectiveness ratio decreased to £29,363 after including patients’ personal costs and lost working time, corresponding to a 50% probability that intensive management is cost-effective at English willingness-to-pay thresholds. Analysing trial baseline predictors showed that remission predictors comprised baseline DAS28-ESR, disability scores and body mass index. A 6-month extension study (involving 95 intensive management patients) showed fewer remissions by 18 months, although more sustained remissions were more likley to persist. Qualitative research in trial completers showed that intensive management was acceptable and treatment support from specialist nurses was beneficial.
Limitations
The main limitations comprised (1) using single time point remissions rather than sustained responses, (2) uncertainty about benefits of different aspects of intensive management and differences in its delivery across centres, (3) doubts about optimal treatment of patients unresponsive to intensive management and (4) the lack of formal international definitions of ‘intensive management’.
Conclusion
The benefits of intensive management need to be set against its additional costs. These were relatively high. Not all patients benefited. Patients with high pretreatment physical disability or who were substantially overweight usually did not achieve remission.
Future work
Further research should (1) identify the most effective components of the intervention, (2) consider its most cost-effective delivery and (3) identify alternative strategies for patients not responding to intensive management.

Abstract
Objectives To summarise radiographic data in randomised controlled trials (RCTs) as part of the radiographic inhibition claim of disease-modifying antirheumatic drugs (DMARDs) approved for patients with rheumatoid arthritis (RA). Methods A systemic literature review was performed using the Medline database from 1994 to February 2020. The results were grouped based on the scoring methods (Sharp, Genant modification, van der Heijde modification) and RA patient populations. Results One hundred sixty-eight publications were selected. After detailed assessment, 52 RCTs (7 methotrexate (MTX)-naive, 23 MTX inadequate response (IR), 9 DMARDs IR and 3 tumour necrosis factor-alpha inhibitors (TNFi) IR studies) were finally included. Information on patient population, scoring method used, reader reliability, statistical analyses and detailed radiographic data on baseline and change scores over multiple follow-up periods are presented. Conclusion The data gathered in this review serve as a repository for the design of future trials with radiographic damage as an outcome.

Abstract
OBJECTIVES To report the efficacy, safety and patient-reported outcome measures (PROs) of tofacitinib modified-release 11 mg once daily plus methotrexate in patients with rheumatoid arthritis (RA) from the open-label phase of Oral Rheumatoid Arthritis Trial (ORAL) Shift. METHODS ORAL Shift was a global, 48-week, phase 3b/4 withdrawal study in patients with moderate to severe RA and an inadequate response to methotrexate. Patients received open-label tofacitinib modified-release 11 mg once daily plus methotrexate; those who achieved low disease activity (LDA; Clinical Disease Activity Index (CDAI)≤10) at week 24 were randomised to receive blinded tofacitinib 11 mg once daily plus placebo (ie, blinded methotrexate withdrawal) or continue with blinded tofacitinib 11 mg once daily plus methotrexate for another 24 weeks. Efficacy, PROs and safety from the open-label phase are reported descriptively. RESULTS Following screening, 694 patients were enrolled and received tofacitinib plus methotrexate in the open-label phase. At week 24, 527 (84.5%) patients achieved CDAI-defined LDA. Improvements from baseline to weeks 12 and 24 were generally observed for all efficacy outcomes (including measures of disease activity, and response, LDA and remission rates) and PROs. Adverse events (AEs), serious AEs and discontinuations due to AEs were reported by 362 (52.2%), 20 (2.9%) and 41 (5.9%) patients, respectively. No deaths were reported. CONCLUSIONS Tofacitinib modified-release 11 mg once daily plus methotrexate conferred improvements in disease activity measures, functional outcomes and PROs, with most (84.5%) patients achieving CDAI-defined LDA after 24 weeks of open-label treatment; the safety profile was generally consistent with the historic safety profile of tofacitinib.Funded by Pfizer Inc; NCT02831855.

Rheumatol Ther 2021; 8:693-710. [PMID: 34037968 PMCID: PMC8217484 DOI: 10.1007/s40744-021-00322-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2021] [Accepted: 05/12/2021] [Indexed: 10/28/2022] Open
Abstract
INTRODUCTION The objective of this study was to evaluate the relative efficacy of targeted immune modulators (TIMs) in TIM-naïve/mixed populations (≤ 20% TIM-experienced) and TIM-experienced (> 20% TIM-experienced) adults with moderate-to-severe rheumatoid arthritis with an inadequate response to or intolerance of conventional disease-modifying antirheumatic drugs (cDMARDs). METHODS A fixed-effects Bayesian network meta-analysis (NMA) was performed using published study-level data from 41 randomized controlled trials (RCTs) identified from two recent systematic literature reviews conducted by the Institute for Clinical and Economic Review, and two additional phase III trials for filgotinib (FINCH-1, FINCH-2). RCTs that compared TIMs with each other, cDMARD therapy, or placebo were included. Treatments included Janus kinase (JAK) inhibitors, tumor necrosis factor α inhibitors (TNFi), and other non-TNFi therapies. Efficacy was defined as achieving remission with a DAS28 score < 2.6 at 12 and 24 weeks. RESULTS In the 12-week analysis for the TIM-naïve/mixed population, all TIMs combined with cDMARD therapy were significantly more likely to achieve remission compared with a cDMARD alone, with intravenous tocilizumab showing a substantially greater magnitude of effect (odds ratio 19.36; 95% credible interval 11.01-38.16). Similarly, in the 24-week analysis, intravenous and subcutaneous tocilizumab showed the highest odds ratio of achieving DAS28 remission compared with cDMARD therapy. Similar trends were observed for the analyses on monotherapy or TIM-experienced population. CONCLUSIONS This NMA demonstrated that tocilizumab is associated with a greater likelihood of remission (DAS28 < 2.6) at 12 and 24 weeks compared with most other TIMs, including new JAK inhibitors, when used in combination with a cDMARD or as monotherapy among TIM-naïve/mixed or TIM-experienced populations.

Real-World Methotrexate Dose on Clinical Effectiveness and Structural Damage of Certolizumab Pegol With Rheumatoid Arthritis. Front Med (Lausanne) 2021; 8:643459.

Abstract
Objective: Rheumatoid arthritis (RA) treatments have markedly advanced with the introduction of biological agents, e. g., tumor necrosis factor (TNF) inhibitors. TNF inhibitors are demonstrated to be quite effective in combination with methotrexate (MTX), and sufficient doses of both agents are important to control RA's disease activity. However, not all RA patients can be treated with high-dose MTX due to contraindications related to the antimetabolite action of MTX or to tolerability concerns. In daily practice, this has resulted in reduced effectiveness of TNF inhibitors. We sought to determine whether the concomitant use of dose of MTX affected the clinical effectiveness, retention rate, and side effects of certolizumab pegol (CZP) for treating RA in a real-world setting. CZP is a pegylated-conjugated Fab' fragment of a humanized anti-TNF antibody that has high affinity to TNF. Patients and Methods: We divided Japanese RA patients treated with CZP (n = 95, 25-83 years old) into groups based on those with (n = 65) and without (n = 30) concomitant MTX and those treated with a high dose (≥8 mg, n = 41) or low dose (1- <8 mg, n = 24) of MTX. We retrospectively analyzed the concomitant MTX doses' effects and side effects and the patient retention rate. Results: There were no significant differences among the CZP groups with and without MTX or the groups receiving the high vs. low MTX doses in the retention rate, the low disease activity rate, or the inhibitory effect in radiographic joint damage. Conclusion: CZP has the potential to be a useful biological agent to control RA's disease activity and the bone destruction in patients who cannot tolerate a sufficient MTX dose.

Abstract
The ongoing opioid crisis highlighted the need for non-steroidal anti-inflammatory drugs (NSAIDs), nonaddictive analgesics against pain, fever, and inflammation. However, NSAIDs may cause gastrointestinal and cardiovascular adverse effects. To avoid systemic toxicity and deliver drugs to diseased tissues, nanotechnology methods of NSAID encapsulation have been reported and some have reached clinical development. Currently, 57 micro- and nanodrugs are approved by the US FDA. Already approved nanoanalgesics have revealed superior efficacy or reduced toxicity compared with placebo or lower doses of systemically administered active comparators. In this review, the evidence for approval of the marketed nanodrugs will be discussed, with a focus on therapies for pain and inflammation. Nanomedicine remains an attractive field for the development of targeted analgesics.

Abstract
Extraintestinal manifestations (EIMs) are frequently observed in IBDs and contribute considerably to morbidity and mortality. They have long been considered a difficult to treat entity due to limited therapy options, but the increasing use of anti-tumour necrosis factors has dramatically changed the therapeutic approach to EIM in recent years. Newly emerging therapies such as JAK inhibitors and anti-interleukin 12/23 will further shape the available armamentarium. Clinicians dealing with EIMs in everyday IBD practice may be puzzled by the numerous available biological agents and small molecules, their efficacy for EIMs and their potential off-label indications. Current guidelines on EIMs in IBD do not include treatment algorithms to help practitioners in the treatment decision-making process. Herein, we summarise knowledge on emerging biological treatment options and small molecules for EIMs, highlight current research gaps, provide therapeutic algorithms for EIM management and shed light on future strategies in the context of IBD-related EIMs.

Abstract
Anti-drug antibodies (ADAs) may develop against originator biologic and biosimilar therapies used for the treatment of psoriasis and may be the cause of initial therapeutic non-response or diminished therapeutic response over time. Comparing immunogenicity between therapeutic agents is challenging owing to the variation in assays used for detection, among other reasons. Using the results of a PubMed search for psoriasis clinical trials disclosing the rates of ADAs for originator biologic and biosimilar therapies approved for the treatment of psoriasis within the last 5 years, this review discusses the rates and potential clinical impact of ADA formation in patients with psoriasis managed with originator biologic and biosimilar therapies, along with novel methods of ADA testing. Anti-drug antibodies are detectable in all biologic and biosimilar therapies approved for the treatment of psoriasis in the last 5 years, and the effect of ADAs on clinical response varies by agent. Novel immunoassays used for the detection of ADAs may have increased sensitivity compared with traditional assays, although the increased rate of detection may not correlate with decreased clinical response and the decision to test for the presence of ADAs may vary from patient to patient. Though ADA formation seems ubiquitous with the use of biologic agents for the treatment of psoriasis, the increased rates of ADAs detected by novel immunoassays may not necessarily correlate with decreased treatment efficacy.

Abstract
INTRODUCTION The PrismRA® test identifies rheumatoid arthritis (RA) patients who are unlikely to respond to anti-tumor necrosis factor (anti-TNF) therapies. This study evaluated the clinical and financial outcomes of incorporating PrismRA into routine clinical care of RA patients. METHODS A decision-analytic model was created to evaluate clinical and economic outcomes in the 12-month period following first biologic treatment. Two treatment strategies were compared: (1) observed clinical decision-making based on a 175-patient cohort receiving an anti-TNF therapy as their first biologic after failure of conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and (2) modeled clinical decision-making of the same population using PrismRA results to inform first-line biologic treatment choice. Modeled costs include biologic drug pharmacy, non-biologic pharmacy, and total medical costs. The odds of inadequate response to anti-TNF therapies and various components of patient care were calculated based on PrismRA results. RESULTS Identifying predicted inadequate responders to anti-TNF therapies resulted in a modeled 38% increase in ACR50 response to first-line biologic therapies. The fraction of patients who achieved an ACR50 response to any therapy (TNFi and others) within the 12-month period was 33% higher in the PrismRA-stratified population than in the unstratified population (59 vs. 44%, respectively). When therapy prescriptions were modeled according to PrismRA results, cost savings were modeled for all financial variables: overall costs (4% decreased total, 19% decreased on ineffective treatments), total biologic drug pharmacy (4% total, 23% ineffective), non-biologic pharmacy (2% total, 19% ineffective), and medical costs (6% total, 19% ineffective). Female sex was the clinical metric that showed the greatest association with inadequate response to anti-TNF therapies (odds ratio 2.42, 95% confidence interval 1.20, 4.88). CONCLUSIONS If PrismRA is implemented into routine clinical care as modeled, predicting which RA patients will have an inadequate response to anti-TNF therapies could save > $7 million in overall ineffective healthcare costs per 1000 patients tested and increase targeted DMARD response rates in RA.

Abstract
CONTEXT AND OBJECTIVE Risk-sharing agreements(RSA) allow decision-makers to manage the uncertainty associated with effectiveness and costs of treatments. Our objective was to estimate the economic impact of RSA implementation on treatment of patients diagnosed with rheumatoid arthritis(RA) with certolizumab pegol(CZP) and assess the potential impact of alternative RSA. METHODS Under original RSA, treatment with CZP was reimbursed when the response was optimal (DAS28 score <3.2) or satisfactory (DAS28 score ≥3.2 and reduction from baseline ≥1.2) at 12 weeks. Alternative RSA would additionally include a 50 % reimbursement for moderate responders(DAS28 score >3.2 and ≤5.1, and reduction from baseline between 0.6 and 1.2). We estimated average savings per patient for hospital's pharmacy service(HPS) at 12 weeks, taking into account the pharmacological cost of CZP. Uncertainty associated with effectiveness of CZP was assessed through 1000 Monte Carlo simulations. RESULTS After 12 weeks of treatment, 57.8 % (n = 52) and 22.2 %(n = 20) of patients had optimal and satisfactory responses, respectively, and average disease activity improved by 1.77 points. Average savings for HPS amounted to 876.9€ and 706.4€ per patient under original and alternative RSA, respectively. Savings in simulated cohort reached 846.2€ and 681.8€ per patient, respectively, leading to estimated net savings for HPS of 846,209€ and 681,790€, respectively. CONCLUSIONS RSA implementation on patients with RA treated with CZP has generated savings and improved efficiency within HPS.

Abstract
INTRODUCTION Opioids are used for severe forms of acute and cancer pain. Over the last years, their potential use in patients with noncancer pain such as those with rheumatoid arthritis (RA) has been postulated. A recent population-based comparative study showed that chronic opioid use was 12% vs. 4% among RA and non-RA patients, respectively. Another study showed an increase from 7.4% to 16.9% (2002 to 2015). In general, there has been an increasing tendency to use opioids in recent years. AREAS COVERED The authors have performed an extensive literature search using PubMed for articles including noncancer pain and the use of the mu opioid receptor (MOR) agonists in patients with RA. EXPERT OPINION Data is not sufficient to support opioid use for the treatment of chronic pain in patients with RA. Data is scarce and inconclusive. Rheumatologists should think and ponder the question: Why is this patient in pain? Differential diagnosis should include a disease flare, degenerative changes of the musculoskeletal system, and fibromyalgia. And while there are new strategies for opioid administration currently being researched, unfortunately, they are far from being applied to human subjects in the everyday clinical setting, and are still being evaluated at an experimental level.

Abstract
Healthcare systems worldwide are struggling to find ways to fund the cost of innovative treatments such as gene therapies, regenerative medicine, and monoclonal antibodies (mAbs). As the world's best known mAbs are close to facing patent expirations, the biosimilars market is poised to grow with the hope of bringing prices down for cancer treatment and autoimmune disorders, however, this has yet to be realized. The development costs of biosimilars are significantly higher than their generic equivalents due to therapeutic equivalence trials and higher manufacturing costs. It is imperative that academics and relevant companies understand the costs and stages associated with biologics processing. This article brings these costs to the forefront with a focus on biosimilars being developed for Rheumatoid Arthritis (RA). mAbs have remarkably changed the treatment landscape, establishing their superior efficacy over traditional small chemicals. Five blockbuster TNFα mAbs, considered as first line biologics against RA, are either at the end of their patent life or have already expired and manufacturers are seeking to capture a significant portion of that market. Although in principle, market-share should be available, withstanding that the challenges regarding the compliance and regulations are being resolved, particularly with regards to variation in the glycosylation patterns and challenges associated with manufacturing. Glycan variants can significantly affect the quality attributes requiring characterization throughout production. Successful penetration of biologics can drive down prices and this will be a welcome change for patients and the healthcare providers. Herein we review the biologic TNFα inhibitors, which are on the market, in development, and the challenges being faced by biosimilar manufacturers.

An open-label randomized controlled trial of DMARD withdrawal in RA patients achieving therapeutic response with certolizumab pegol combined with DMARDs. Rheumatology (Oxford) 2020; 59:1522-1528. [PMID: 31628486 DOI: 10.1093/rheumatology/kez470] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2019] [Revised: 09/09/2019] [Indexed: 02/05/2023] Open
Abstract
OBJECTIVES The objective of this trial was to compare effectiveness of certolizumab pegol added to conventional synthetic DMARDs (csDMARDs) in RA patients, followed by continuing vs discontinuing background csDMARDs after treatment response. METHODS Patients with active RA who had certolizumab pegol added to their existing csDMARD regimen due to inadequate response were eligible. At 3 or 6 months, patients who achieved a change (Δ) in DAS28 of ⩾1.2 were randomized to continue combination therapy (COMBO) or withdraw csDMARD therapy (MONO) (unblinded). The primary outcome was non-inferiority of stopping vs continuing csDMARD(s) in terms of maintaining ΔDAS28 ⩾ 1.2 or achieving DAS28 low disease activity at 18 months (non-inferiority margin: 15 percentile units). RESULTS A total of 125 patients were enrolled, 88 randomized to COMBO (n = 43) or MONO (n = 45). No significant differences were observed between groups in baseline age, gender, race, RF status or prior biologics (16% vs 11%). Although the rate of ΔDAS28 ⩾ 1.2 and/or DAS28 low disease activity achievement at 18 months was clinically comparable between the two groups (72% vs 69%), non-inferiority assumptions were not met [absolute risk difference (upper limit of 90% CI): 2.6% (19.1%)]. Similar baseline-adjusted improvements were seen in DAS28 (COMBO vs MONO: -2.3 vs -2.1; P = 0.49) and all endpoints were not statistically different including 59% vs 56% achieved DAS28 low disease activity, 69% vs 59% ΔDAS28 ⩾ 1.2, and 41% each remission. CONCLUSION Among RA patients achieving a therapeutic response on combination therapy with certolizumab pegol and csDMARDs, withdrawing csDMARDs was not non-inferior to maintaining csDMARDs but improvements were sustained in both groups at 18 months.

Abstract
INTRODUCTION In the last 20 years, biologic and targeted synthetic disease-modifying antirheumatic drugs (DMARDs) have become available for treating rheumatoid arthritis (RA), and a treat-to-target strategy has been introduced. We hypothesise that these advances should have resulted in changes to the characteristics of patients with RA participating in clinical trials of the newest therapies. This study determined whether the baseline characteristics of patients with RA enrolled in clinical trials have changed in the past decade versus patients participating in earlier RA studies. METHODS This secondary analysis was based on randomised controlled trials (RCTs) identified in a systematic literature review. Baseline characteristics of patients with RA with inadequate response to conventional synthetic DMARDs were compared between RCTs published in 1999-2009 and those published in 2010-2017 using random-effects meta-analyses. RESULTS Forty RCTs were analysed: 22 from 1999-2009 and 18 from 2010-2017. No significant difference between the two timeframes and no obvious trend over time were observed for age, gender, disease duration, rheumatoid factor status, tender and swollen joint counts, physician and patient global assessments of disease activity, and pain scores. Variability between RCTs was high. Similar results were observed for Disease Activity Scores and Health Assessment Questionnaire-Disability Index scores, but with low variability between RCTs. CONCLUSION The baseline characteristics of patients with RA participating in RCTs do not appear to have changed in the last decade despite the availability of new treatments and a different treatment approach. Further research should determine the impact of baseline patient characteristics on patients' response to RA treatments.

Abstract
Importance Large placebo responses in randomized clinical trials may keep effective medication from reaching the market. Primary outcome measures of clinical trials have shifted from patient-reported to objective outcomes, partly because response to randomized placebo treatment is thought to be greater in subjective compared with objective outcomes. However, a direct comparison of placebo response in subjective and objective outcomes in the same patient population is missing. Objective To assess whether subjective patient-reported (pain severity) and objective inflammation (C-reactive protein [CRP] level and erythrocyte sedimentation rate [ESR]) outcomes differ in placebo response. Design, Setting, and Participants The placebo arms of 5 double-blind, randomized, placebo-controlled clinical trials were included in this cross-sectional study. These trials were conducted internationally for 24 weeks or longer between 2005 and 2009. All patients with rheumatoid arthritis randomized to placebo (N = 788) were included. Analysis of data from these trials was conducted from March 27 to December 31, 2019. Intervention Placebo injection. Main Outcomes and Measures The difference (with 95% CIs) from baseline at week 12 and week 24 on a 0- to 100-mm visual analog scale to evaluate the severity of pain, CRP level, and ESR. Results Of the 788 patients included in the analysis, 644 were women (82%); mean (SD) age was 51 (13) years. There was a statistically significant decrease in patient-reported pain intensity (week 12: -14 mm; 95% CI, -12 to -16 mm and week 24: -20 mm; 95% CI, -16 to -22 mm). Similarly, significant decreases were noted in the CRP level (week 12: -0.51 mg/dL; 95% CI, -0.47 to -0.56 mg/dL and week 24: -1.16 mg/dL; 95% CI, -1.03 to -1.30 mg/dL) and ESR (week 12: -11 mm/h; 95% CI, -10 to 12 mm/h and week 24: -25 mm/h; 95% CI, -12 to -26 mm/h) (all P < .001). Conclusions and Relevance The findings of this study suggest that improvements in clinical outcomes among participants randomized to placebo were not limited to subjective outcomes. Even if these findings could largely demonstrate a regression to the mean, they should be considered for future trial design, as unexpected favorable placebo responses may result in a well-designed trial becoming underpowered to detect the treatment difference needed in clinical drug development.

Abstract
Introduction/objectives To evaluate the incidence rate (IR) of tuberculosis (TB) and viral hepatitis B and C (HBV/HCV) during certolizumab pegol (CZP) treatment, worldwide and in Asia-Pacific countries, across clinical trials and post-marketing reports (non-interventional studies and real-world practice). Method CZP safety data were pooled across 49 clinical trials from 1998 to June 2017. Post-marketing reports were from initial commercialization until March 2015 (TB)/February 2017 (HBV/HCV). All suspected TB and HBV/HCV cases underwent centralized retrospective review by external experts. Incidence rates (IRs) were calculated per 100 patient-years (PY) of CZP exposure. Results Among 11,317 clinical trial patients (21,695 PY), 62 TB cases were confirmed (IR 0.29/100 PY) including 2 in Japan (0.10/100 PY) and 3 in other Asia-Pacific countries (0.58/100 PY). From > 238,000 PY estimated post-marketing CZP exposure, there were 31 confirmed TB cases (0.01/100 PY): 5 in Japan (0.05/100 PY), 1 in other Asia-Pacific countries (0.03/100 PY). Reported regional TB IRs were highest in eastern Europe (0.17/100 PY), central Europe (0.09/100 PY), and Mexico (0.16/100 PY). Across clinical trials, there was 1 confirmed HBV reactivation and no HCV cases. From > 420,000 PY estimated post-marketing CZP exposure, 5 HBV/HCV cases were confirmed (0.001/100 PY): 2 HCV reactivations; 1 new HCV; plus 2 HBV reactivations in Japan (0.008/100 PY). Conclusions CZP TB risk is aligned with nationwide TB rates, being slightly higher in Asia-Pacific countries excluding Japan. Overall, TB and HBV/HCV risk with CZP treatment is currently relatively low, as risk can be minimized with patient/physician education, screening, and vigilant treatment, according to international guidelines.Key Points: • TB rates were highest in eastern/central Europe, Mexico, and Asia-Pacific regions. • With the implementation of stricter TB screening and risk evaluations in 2007, especially in high TB incidence countries, there was a notable reduction TB occurrence. • Safety profile of biologics in real-world settings complements controlled studies. • TB and hepatitis (HBV/HCV) risk with certolizumab pegol (CZP) treatment is low. |

Abstract
Anti-tumor necrosis factor (anti-TNF) drugs are often prescribed for the treatment of rheumatoid arthritis (RA) and other immune-mediated inflammatory diseases. Although this treatment has been shown to be effective in many patients, up to 40% of patients do not achieve disease control. Drug concentration in plasma may be a factor affecting the observed variability in therapeutic response. In this study, we aimed to identify the plasma concentrations of the anti-TNF certolizumab pegol (CZP), associated with improvement in disease activity in patients with RA. Data were pooled from three randomized, controlled clinical trials with a combined total of 1,935 patients analyzed. Clinical outcomes of low disease activity (LDA) and remission were defined as Disease Activity Score in 28 joints with C-reactive protein (DAS28(CRP)) ≤ 2.7 and < 2.3, respectively. Quartile analysis results indicated that there may be an exposure-response relationship between CZP concentration and LDA/remission outcomes at weeks 12 and 24; the association was strongest for LDA (P < 0.05). Receiver operating characteristic (ROC) analysis showed that CZP concentrations ≥ 28.0 μg/ml at week 12, and ≥ 17.6 μg/ml at week 24, were associated with a greater likelihood of achieving LDA/remission outcomes. Although confirmatory studies are warranted to define the optimal CZP therapeutic range at weeks 12 and 24, these data indicate that CZP concentrations may be associated with improvement of disease activity.

Abstract
Abstract
Objectives
Small molecule tyrosine kinase inhibitors [smTKI, comprising mostly of Janus kinase (JAK) and to a lesser extent, spleen tyrosine kinase (SyK) inhibitors] modulate the cytokine receptor-mediated intracellular signal cascade, and are an effective treatment for autoimmune diseases and malignancies. As smTKI are novel, long-term safety is uncertain. Due to increasing use, characterization of their true adverse event profile is critical.
Methods
We performed a systematic review and meta-analysis of all published trial data on the pulmonary and serious adverse effects of smTKIs in autoimmune disease. EMBASE, MEDLINE, CENTRAL and Pneumotox databases were searched up to April 2019 for randomized controlled trials, observational studies and post marketing surveillance, comparing any smTKI with placebo or another therapy, or as monotherapy at different doses. Primary outcomes comprised of any respiratory complications including upper and lower respiratory tract infections (URTI, LRTI), influenza, pneumonia, opportunistic respiratory infections, drug-induced interstitial lung disease, pulmonary embolism and lung neoplasm.
Results
We identified 4667 citations for screening, and selected 319 studies for full text review. Seventy-nine studies were analysed, including 47 randomized controlled trials, 25 observational studies and seven post-marketing surveillance studies, comprising 159 652 participants. There were significantly increased risks of URTI [risk difference (RD) 0.03; 95% CI: 0.01, 0.05; P = 0.00; 36 studies, 14 724 participants], LRTI (RD 0.01; 95% CI: 0.00, 0.02; P = 0.02; 24 studies, 12 302 participants), influenza (RD 0.01; 95% CI: 0.00, 0.01; P = 0.04; 22 studies, 10 684 participants), and pneumonia (RD 0.00; 95% CI: 0.00, 0.01; P = 0.02; 33 studies, 15 511 participants). No increased risk was found for other respiratory complications, including pulmonary embolism.
Conclusion
SmTKI increases the risk of non-opportunistic respiratory infections compared with placebo. The risk of any serious pulmonary adverse events is low.

Abstract
BACKGROUND/OBJECTIVES This article compares the effectiveness of baricitinib (BARI) 4 mg (oral, Janus kinase [JAK] 1/2 inhibitor) versus other targeted synthetic/biologic disease-modifying antirheumatic drugs, in combination with methotrexate (MTX), in moderate-to-severe rheumatoid arthritis patients with inadequate response (IR) to MTX. METHODS A systematic literature review was conducted to identify randomized controlled trials (RCTs) of the interventions of interest. Bayesian network meta-analyses (NMA) were used to compare American College of Rheumatology (ACR) responses at 24 weeks. A series of prespecified sensitivity analyses addressed the potential impact of, among others, baseline risk, treatment effect modifiers, and trial design on treatment response. RESULTS Nineteen RCTs were included in the NMA (primary analysis). For ACR20, BARI 4 mg + MTX was found to be more effective than adalimumab (ADA) 40 mg + MTX (Odds Ratio [OR] 1.33), abatacept (ABA) 10 mg + MTX (IV/4 weeks) (OR 1.45), infliximab (IFX) 3 mg + MTX (IV/8 wks) (OR 1.63), and rituximab (RTX) 1000 mg + MTX (OR 1.63). No differences were found on ACR50. For ACR70, BARI 4 mg + MTX was more effective than ADA 40 mg + MTX (OR 1.37), ABA 10 mg + MTX (OR 1.86), and RTX 1000 mg + MTX (OR 2.26). Sensitivity analysis including 10 additional RCTs with up to 20% of patients with prior biologic use showed BARI 4 mg + MTX to be more effective than tocilizumab (TCZ) 8 mg + MTX on ACR20 (OR 1.44). Results for all sensitivity analyses were consistent with the direction and magnitude of the primary results. Key limitations include the time span in which trials were conducted (1999-2017), during which patient characteristics and treatment approaches might have changed. CONCLUSION This NMA suggests that BARI 4 mg + MTX is an efficacious treatment option in the MTX-IR population as evidenced by the robustness of results.

Experience of a Performance-Based Risk-Sharing Arrangement for the Treatment of Rheumatoid Arthritis With Certolizumab Pegol. Value Health Reg Issues 2020; 21:201-204. [PMID: 32199257 DOI: 10.1016/j.vhri.2020.01.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2019] [Revised: 10/15/2019] [Accepted: 01/06/2020] [Indexed: 10/24/2022]
Abstract
OBJECTIVES To describe the process and results of the implementation of a performance-based risk-sharing arrangement for the use of certolizumab pegol (Cimzia) in patients with rheumatoid arthritis (RA), based on rational pharmacotherapy. METHODS In 2014, the area of Management of Drugs and Supplies of the health maintenance organization of the Hospital Italiano de Buenos Aires signed a performance-based risk-sharing arrangement with Montpellier Laboratory for the use of certolizumab pegol in patients with RA. The laboratory would reimburse the hospital the cost of the first 10 doses of the drug if an optimal clinical response was not achieved (difference greater than or equal to 1.2 in the Disease Activity Score 28 with erythrocyte sedimentation [Δ DAS28 ESR] measured at the beginning and at the end), or if the patient presented with an adverse drug reaction, during the first 12 weeks of treatment. RESULTS Forty patients with RA were included between September 2014 and January 2018. Thirty-six patients completed 12 weeks of treatment, of which 25 (69.4 %) had an optimal clinical response (Δ DAS28 ESR ≥ 1.2). The laboratory reimbursed the hospital 116 doses of certolizumab pegol, corresponding to 12 patients (12 of 40, 30%). Eleven of them did not reach the optimal clinical response, and 1 presented with an adverse drug reaction. CONCLUSIONS The performance-based risk-sharing arrangement proved to be a useful tool to optimize the resources of the healthcare payer and contributed to the collection of scientific evidence in real-life patients.

Abstract
Biological disease-modifying antirheumatic drugs (bDMARDs) are highly effective agents for the treatment of inf lammatory arthritis; however, they also possess a potential risk for serious infection. Recently, with the rapid expansion of the bDMARDs market in Korea, reports of serious adverse events related to the agents have also increased, necessitating guidance for the use of bDMARDs. Current work entitled, "Expert consensus for the use of bDMARDs drugs for inflammatory arthritis in Korea," is the first to describe the appropriate use of bDMARDs in the management of inflammatory arthritis in Korea, with an aim to provide guidance for the local medical community to improve the quality of clinical care. Twelve consensus statements regarding the use of bDMARDs for the management of rheumatoid arthritis and ankylosing spondylitis were generated. In this review, we provide detailed guidance on bDMARDs use based on expert consensus, including who should prescribe, the role of education, indications for use, and monitoring strategies for safety.

Associations between certolizumab pegol serum levels, anti-drug antibodies and treatment response in patients with inflammatory joint diseases: data from the NOR-DMARD study. Arthritis Res Ther 2019; 21:256. [PMID: 31783773 PMCID: PMC6883678 DOI: 10.1186/s13075-019-2009-5] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2019] [Accepted: 09/23/2019] [Indexed: 12/14/2022] Open
Abstract
OBJECTIVES To identify a therapeutic target interval for certolizumab pegol drug levels and examine the influence of anti-drug antibodies in patients with inflammatory joint diseases. METHODS Certolizumab pegol and anti-drug antibody levels were measured in serum samples collected after 3 months of certolizumab pegol treatment in 268 patients with inflammatory joint diseases (116 axial spondyloarthritis, 91 rheumatoid arthritis and 61 psoriatic arthritis) in the NOR-DMARD study. Treatment response was defined by Ankylosing Spondylitis Disease Activity Score Clinically important improvement in axial spondyloarthritis, European League Against Rheumatism good/moderate response in rheumatoid arthritis, and improvement in 28-joint Disease Activity Score of ≥ 0.6 in PsA. Serum drug levels and anti-drug antibodies were analysed using automated in-house assays. RESULTS Certolizumab pegol serum levels varied considerably between individuals (median (IQR) 32.9 (17.3-43.9) mg/L). Certolizumab pegol level ≥ 20 mg/L was associated with treatment response for the total inflammatory joint disease population, with odds ratio (OR) 2.3 (95% CI 1.2-4.5, P = 0.01) and OR 1.9 (95% CI 1.0-3.5, P = 0.05) after 3 and 6 months of treatment, respectively. For individual diagnoses, this association was most consistent for axial spondyloarthritis, with OR 3.4 (95% CI 1.0-11.1, P < 0.05) and OR 3.3 (95% CI 1.0-10.8, P < 0.05), respectively. Certolizumab pegol level > 40 mg/L was not associated with any additional benefit for any of the diagnoses. Anti-drug antibodies were detected in 6.1% (19/310) of samples and were associated with low certolizumab pegol levels (P < 0.01). CONCLUSIONS Serum certolizumab pegol levels 20-40 mg/L were associated with treatment response in inflammatory joint diseases. Our study is the first to show this association in axial spondyloarthritis and psoriatic arthritis patients. The results suggest a possible benefit of therapeutic drug monitoring in patients with inflammatory joint disease on certolizumab pegol treatment. TRIAL REGISTRATION NCT01581294, April 2012.

Abstract
Quantitative systems pharmacology (QSP) approaches have been increasingly applied in the pharmaceutical since the landmark white paper published in 2011 by a National Institutes of Health working group brought attention to the discipline. In this perspective, we discuss QSP in the context of other modeling approaches and highlight the impact of QSP across various stages of drug development and therapeutic areas. We discuss challenges to the field as well as future opportunities.

Abstract
Objectives: To report changes in productivity and social participation - alongside clinical and patient-reported outcomes (PROs) - in patients with rheumatoid arthritis (RA) receiving certolizumab pegol (CZP) during routine clinical practice in Belgium. Methods: This was a prospective, non-interventional study, in which patients were prescribed CZP at their physicians' discretion and followed during routine clinical visits. The primary outcomes were household productivity and social participation at the last visit (~52 weeks), measured through responses to the Work Productivity Survey. Secondary outcomes included workplace productivity and achievement of DAS28(ESR) clinical response, low disease activity and remission at the last visit. Baseline demographics and adverse events (AEs) were recorded for all patients who received ≥1 dose CZP. Results: A total of 141 patients were enrolled in the study, of whom 119 (84.4%) formed the full analysis set (received ≥1 dose CZP and had ≥1 post-baseline measurement for ≥1 primary outcome). At Visit 1 (baseline), patients reported an average of 11.0 paid work days, 16.8 household work days and 5.5 days of social participation affected by their disease over the previous month. Rapid improvements in household productivity and social participation were evident from Visit 2 (2-8 weeks). By the final visit, mean improvements were observed for all aspects of productivity, participation and clinical/PROs. A total of 24 AEs were reported. Conclusion: CZP has a positive impact on productivity and social participation in patients with RA in the Belgian daily practice setting, with safety and efficacy profiles that mirror those observed in the trial setting.

Effectiveness, Tolerability, and Safety of Tofacitinib in Rheumatoid Arthritis: A Retrospective Analysis of Real-World Data from the St. Gallen and Aarau Cohorts. J Clin Med 2019; 8:jcm8101548. [PMID: 31561582 PMCID: PMC6832556 DOI: 10.3390/jcm8101548] [Citation(s) in RCA: 30] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2019] [Revised: 09/22/2019] [Accepted: 09/24/2019] [Indexed: 12/20/2022] Open
Abstract
: Introduction: Tofacitinib is an oral JAK inhibitor indicated for the treatment of rheumatoid arthritis (RA). The efficacy and safety of tofacitinib have been shown in several randomized clinical trials. The study presented here aimed to assess the clinical tolerability and effectiveness of tofacitinib among RA patients in real life. Methods: Consecutive patients between January 2015 and April 2017 with RA who fulfilled the American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) 2010 criteria were included in a prospectively designed analysis of retrospective data. Patients were initiated on tofacitinib 5 mg bid. The primary objective was to analyze the safety of tofacitinib in a real-life cohort. Safety was assessed by the reasons to stop tofacitinib during follow up and changes of liver enzymes, hemoglobin, and creatinine. The secondary outcome was to analyze the frequency of and time to achieve low disease activity (LDA) and remission as defined by 28 joint count disease activity score (DAS28). Results: A total of 144 patients were treated with tofacitinib. A total of 84.9% of patients were pre-exposed to at least one biological agent. The average DAS28 at the initiation of tofacitinib was 4.43. A total of 50.0% of patients were positive for rheumatoid factor and 49.0% for ACPA. The mean follow up was 1.22 years (range 10d-3.7a) after initiation of tofacitinib treatment. A total of 94 (64.4%) patients remained on tofacitinib during follow-up. The average time to stop tofacitinib was 190.0 days. Reasons to stop tofacitinib were: insufficient response (n = 23), gastrointestinal symptoms (n = 18), infection (n = 5), myalgia (n = 2), remission (n = 2), headache (n = 2), cough, blue finger syndrome, intolerance, heartburn, psoriasis, and increased liver enzymes (all n = 1). Increased alanine amino transferase (ALAT) or aspartate amino transferase (ASAT) > 2× upper limit of normal (ULN) were detected in 3.3% and 4.4% of patients, respectively. Hemoglobin decrease of >10% was detected in 15.1% of the patients and decreased lymphocytes <500/μL in 3.4%. An increase of creatinine >20% was detected in 9.4% of patients. A total of 62.9% and 50.0% of the patients achieved low disease activity (LDA) or remission after a median of 319 and 645 days, respectively. These rates were significantly higher in patients naïve to biologic agents as compared to patients pre-exposed to biologics (LDA: naïve 100% 92 d, pre-exposed 57.0% 434 d, p ≤ 0.001; remission: naïve 86.7% 132 d, pre-exposed 44.1%, 692 d, p = 0.001). Conclusions: Tofacitinib is a safe and effective treatment option for patients with RA. Tofacitinib may induce high rates of LDA and remission in patients with active disease, even after the use of one or more biologics, though the rate appeared higher in patients naïve to biologics. Tofacitinib may be a valuable option in a treat-to-target approach. Our data demonstrate that Janus kinase (JAK) inhibitors are safe and efficacious in real life patients.

Different Original and Biosimilar TNF Inhibitors Similarly Reduce Joint Destruction in Rheumatoid Arthritis-A Network Meta-Analysis of 36 Randomized Controlled Trials. Int J Mol Sci 2019; 20:ijms20184350. [PMID: 31491879 PMCID: PMC6770755 DOI: 10.3390/ijms20184350] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2019] [Revised: 08/24/2019] [Accepted: 08/29/2019] [Indexed: 11/17/2022] Open
Abstract
The effect of five approved tumour necrosis factor inhibitors (TNFi: infliximab, etanercept, adalimumab, certolizumab, and golimumab) on joint destruction in rheumatoid arthritis (RA) have been compared versus methotrexate (MTX) in randomized controlled trials (RCTs) but have not been compared directly to each other or to an otherwise untreated placebo control. The present analysis compares effects of standard doses, high doses, and low doses of TNFis on radiographic joint destruction in RA and relate these effects to MTX and placebo by means of a Bayesian network meta-analysis. We identified 31 RCTs of the effect of TNFis on joint destruction and 5 RCTs with controls, which indirectly could link otherwise untreated placebo controls to the TNFi treatments in the network. The previously untested comparison with placebo was performed to estimate not only the effect relative to another drug, but also the absolute attainable effect. Compared to placebo there was a highly significant inhibitory effect on joint destruction of infliximab, etanercept, adalimumab, certolizumab, and golimumab, which was about 0.9% per year as monotherapy and about 1.2% per year when combined with MTX. Although significantly better than MTX and placebo, golimumab seemed inferior to the remaining TNFis. There was no difference between original reference drugs (Remicade, Enbrel) and the almost identical copy drugs (biosimilars).
