Barriers to, Facilitators of, and Interventions to Support Treat-to-Target Implementation in Rheumatoid Arthritis: A Systematic Review.

OBJECTIVE: Treat-to-target (T2T) is recommended in the management of rheumatoid arthritis (RA) but its implementation is suboptimal. We aimed to identify interventional strategies targeted at improving T2T implementation in RA by systematically reviewing published evidence on barriers to, facilitators of, and interventions to support T2T implementation. METHODS: Systematic and scoping literature searches in PubMed/MEDLINE®, BIOSIS Previews®, Derwent Drug File, Embase®, EMCare®, International Pharmaceutical Abstracts, and SciSearch® were conducted to identify barriers/facilitators and interventions relating to T2T implementation in RA. The quality of included studies was assessed using Critical Appraisal Skills Programme (CASP) checklists. Data related to barriers/facilitators and interventions were extracted, grouped, and summarized descriptively, and a narrative synthesis was generated. RESULTS: In total, 146 articles were analyzed, of which 123 (84%) included ≥50% of the items assessed by CASP checklists. Of the 146 studies, 76 evaluated T2T barriers and facilitators, from which 329 relevant statements were identified and regrouped into 18 target areas, including: healthcare professionals' (HCPs') or patients' knowledge or perceptions; patient-HCP communication or alignment; and time or resources. Overall, 56 interventions were identified from 70 studies across the 18 target areas; 54% addressed disease activity or patient-reported outcome assessments. Of the 56 interventions identified, 36 improved T2T implementation and/or patient outcomes in RA. CONCLUSION: Despite long-established T2T recommendations, there remain many barriers to its implementation. Interventions to improve T2T should be developed further and assessed, with a particular focus on tailoring them to individual countries, regions, and healthcare settings.

Safety and Efficacy of Upadacitinib in Patients with Rheumatoid Arthritis Refractory to Biologic DMARDs: Results Through Week 216 from the SELECT-CHOICE Study.

INTRODUCTION: The safety and efficacy of upadacitinib 15 mg (UPA15) through week 216 was evaluated in patients with rheumatoid arthritis (RA) from the long-term extension (LTE) of the phase 3 SELECT-CHOICE study. METHODS: Patients with RA refractory to biologic disease-modifying antirheumatic drugs (bDMARDs) were randomized to UPA15 or abatacept (ABA) for 24 weeks. During the open-label LTE, patients on ABA switched to UPA15 at week 24, and those on UPA15 continued treatment. The safety and efficacy of continuous UPA15, and ABA to UPA15, are summarized through week 216. RESULTS: The LTE was comprised of 91.4% (n = 277/303) of patients that initially received UPA15, and 89.6% (n = 277/309) that initially received ABA. Of patients on UPA15 in the LTE (n = 547), 28.3% (n = 155/547) discontinued the study drug by week 216. Relative to other adverse events of special interest, and largely consistent with previous findings at week 24, higher rates of serious infection, COVID-19, herpes zoster, and elevated creatine phosphokinase were reported, while rates of malignancy excluding nonmelanoma skin cancer (NMSC), NMSC, major adverse cardiovascular event (MACE), and venous thromboembolism (VTE) were low. Long-term safety data with UPA through week 216 aligned with previous observations and no new safety risks were identified, including in patients who switched from ABA to UPA15. Proportions of patients achieving 28-joint disease activity score based on C-reactive protein (DAS28[CRP]) < 2.6/ ≤ 3.2, clinical disease activity index (CDAI) and simple disease activity index (SDAI) low disease activity/remission, ≥ 20%/50%/70% improvement in the American College of Rheumatology (ACR20/50/70) response criteria, and Boolean remission were maintained or improved with UPA15 through week 216. Improvements in the Health Assessment Questionnaire-Disability Index (HAQ-DI), patient's assessment of pain, and Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) were also maintained or improved with UPA15 through week 216. Across all efficacy endpoints, similar results were observed in patients who switched from ABA to UPA15 versus continuous UPA15. Patients with an inadequate response to ≥ 1 prior tumor necrosis factor (TNF) inhibitor (UPA15: n = 263/303, 86.8%; ABA to UPA15: n = 273/309, 88.3%) showed similar responses to the total population. CONCLUSIONS: The long-term safety profile of UPA was consistent with previous findings and the broader RA clinical program. Compared to the primary analyses at week 24, efficacy responses were maintained or further improved with UPA15 through week 216 in patients with RA. Trial registration, ClinicalTrials.gov identifier: NCT03086343.

A long-term study looked at a drug named upadacitinib to treat people with rheumatoid arthritis (RA), a disease that causes joint pain and damage. The study included patients whose RA was not improved by other injectable medicines. The study compared upadacitinib with another drug called abatacept. After 24 weeks, patients who were taking abatacept switched to upadacitinib, and patients taking upadacitinib continued on upadacitinib treatment for over 4 years. The researchers looked at how well the treatments worked over the long-term and if there were any side effects. The side effects with upadacitinib treatment in this long-term study were similar to side effects reported in previous studies with upadacitinib. The researchers also found that upadacitinib helped to lessen the symptoms of RA over time and helped patients complete their daily activities and reduced their pain and tiredness. This was true for patients who switched from abatacept to upadacitinib after 24 weeks and for patients who took upadacitinib from the start of the study. Patients who had not responded to other medicines also had similar improvements with upadacitinib. In conclusion, upadacitinib can help people with RA over the long term and no new safety risks were found.

Differential properties of Janus kinase inhibitors in the treatment of immune-mediated inflammatory diseases.

Janus kinases (JAKs) are a family of cytosolic tyrosine kinases that regulate cytokine signal transduction, including cytokines involved in a range of inflammatory diseases, such as RA, psoriasis, atopic dermatitis and IBD. Several small-molecule JAK inhibitors (JAKis) are now approved for the treatment of various immune-mediated inflammatory diseases. There are, however, key differences between these agents that could potentially translate into unique clinical profiles. Each JAKi has a unique chemical structure, resulting in a distinctive mode of binding within the catalytic cleft of the target JAK, and giving rise to distinct pharmacological characteristics. In addition, the available agents have differing selectivity for JAK isoforms, as well as off-target effects against non-JAKs. Other differences include effects on haematological parameters, DNA damage repair, reproductive toxicity and metabolism/elimination. Here we review the pharmacological profiles of the JAKis abrocitinib, baricitinib, filgotinib, peficitinib, tofacitinib and upadacitinib.

The effect of antimalarials on the safety and persistence of treatment with biologic agents or Janus kinase inhibitors in rheumatoid arthritis.

OBJECTIVES: To test the association of use of antimalarials with the overall safety of treatment in RA patients receiving one or multiple courses of biologic (b)DMARDs or a Janus kinase inhibitor (JAKi). METHODS: BiobadaBrasil is a multicentric registry-based cohort study of Brazilian patients with rheumatic diseases starting their first bDMARD or JAKi. The present analysis includes RA patients recruited from January 2009 to October 2019, followed up over one or multiple (up to six) courses of treatment (latest date, 19 November 2019). The primary outcome was the incidence of serious adverse events (SAEs). Total and system-specific adverse events (AEs) and treatment interruption served as secondary outcomes. Negative binomial regression with generalized estimating equations (to estimate multivariate incidence rate ratios, mIRR) and frailty Cox proportional hazards models were used for statistical analyses. RESULTS: The number of patients enrolled was 1316 (2335 treatment courses, 6711 patient-years [PY]; 1254.5 PY on antimalarials). The overall incidence of SAEs was 9.2/100 PY. Antimalarials were associated with reduced risk of SAEs (mIRR: 0.49; 95% CI: 0.36, 0.68; P < 0.001), total AEs (0.68; 95% CI: 0.56, 0.81; P < 0.001), serious infections (0.53; 95% CI: 0.34, 0.84; P = 0.007) and total hepatic AEs (0.21; 95% CI: 0.05, 0.85; P = 0.028). Antimalarials were also related to better survival of treatment course (P = 0.003). There was no significant increase in the risk of cardiovascular AEs. CONCLUSION: Among RA patients on treatment with bDMARDs or JAKi, concomitant use of antimalarials was associated with reduced the incidence of serious and total AEs and with longer treatment course survival.

Funcionality assessed by the core set of the international classification of functionality and health for rheumatoid arthritis: A cohort study.

OBJECTIVE: The aim of this study was to evaluate the function of a cohort of patients with rheumatoid arthritis (RA) from the core set of the International Classification of Functioning and Health (ICF) for RA over 12 months. METHODS: We used prospective longitudinal data to conduct a cohort study among a well-characterized group of RA patients. Ninety RA patients aged between 40 and 70 years were included in the study. Patients were evaluated at baseline and after 12 months. Age, disease duration, current smoking, erosions, disease activity, functional test, disability and physical activity were evaluated. Then, the ICF core set classification for RA was applied. RESULTS: 81 patients completed the assessments, the majority of patients were female (88.9%) and the mean age was 56.5 ± 7.3 years. At baseline, the median disease activity was 3.0. There was a statistically significant (p < 0.02) improvement in "Exercise tolerance functions" over 12 months and also a statistically significant (p < 0.001) decrease in "Muscle strength functions" over 12 months. The activity and participation domain showed a weak correlation with the clinical data of the DAS28-PCR (p<0.02). CONCLUSION: We conclude that relevant aspects of the ICF Core Set for RA were able to adequately express the physical and functional factors of the RA cohort. This tool provides a common language for the interdisciplinary team, which can enhance the use of timely interventions to prevent physical disability in clinical practice.

Urinary metabolomic biomarker candidates for skeletal muscle wasting in patients with rheumatoid arthritis.

BACKGROUND: Rheumatoid arthritis (RA) is an autoimmune disease that affects the joints, leading to chronic synovial inflammation and local tissue destruction. Extra-articular manifestations may also occur, such as changes in body composition. Skeletal muscle wasting is often observed in patients with RA, but methods for assessing loss of muscle mass are expensive and not widely available. Metabolomic analysis has shown great potential for identifying changes in the metabolite profile of patients with autoimmune diseases. In this setting, urine metabolomic profiling in patients with RA may be a useful tool to identify skeletal muscle wasting. METHODS: Patients aged 40-70 years with RA have been recruited according to the 2010 ACR/EULAR classification criteria. Further, the Disease Activity Score in 28 joints using the C-reactive protein level (DAS28-CRP) determined the disease activity. The muscle mass was measured by Dual X-ray absorptiometry (DXA) to generate the appendicular lean mass index (ALMI) by summing the lean mass measurements for both arms and legs and dividing them by height squared (kg/height2 ). Finally, urine metabolomic analysis by 1 H nuclear magnetic resonance (1 H-NMR) spectroscopy was performed and the metabolomics data set analysed using the BAYESIL and MetaboAnalyst software packages. Principal component analysis (PCA) and partial least squares-discriminant analysis (PLS-DA) were applied to the 1 H-NMR data, followed by Spearman's correlation analysis. The combined receiver operating characteristic curve (ROC) was calculated, as well as the logistic regression analyses to establish a diagnostic model. The significance level at P < 0.05 was set for all analyses. RESULTS: The total set of subjects investigated included 90 patients with RA. Most patients were women (86.7%), with a mean age of 56.5 ± 7.3 years old and a median DAS28-CRP of 3.0 (IQR 1.0-3.0). Fifteen metabolites were identified in the urine samples with high variable importance in projection (VIP scores) by MetaboAnalyst. Of these, dimethylglycine (r = 0.205; P = 0.053), oxoisovalerate (r = -0.203; P = 0.055), and isobutyric acid (r = -0.249; P = 0.018) were significantly correlated with ALMI. Based on the low muscle mass (ALMI ≤6.0 kg/m2 for women and ≤8.1 kg/m2 for men) a diagnostic model have been established with dimethylglycine (area under the curve [AUC] = 0.65), oxoisovalerate (AUC = 0.49), and isobutyric acid (AUC = 0.83) with significant sensitivity and specificity. CONCLUSIONS: Isobutyric acid, oxoisovalerate, and dimethylglycine from urine samples were associated with low skeletal muscle mass in patients with RA. These findings suggest that this group of metabolites may be further tested as biomarkers for identification of skeletal muscle wasting.

Efficacy of certolizumab pegol across baseline rheumatoid factor subgroups in patients with rheumatoid arthritis: Post-hoc analysis of clinical trials.

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

Factors associated with poor outcomes in SLE patients with COVID-19: Data from ReumaCoV-Brazil register.

OBJECTIVES: To evaluate factors associated with COVID-19 severity outcomes in patients with systemic lupus erythematosus (SLE). METHODS: This was a cross-sectional analysis of baseline data of a prospective, multi-stage cohort study-"The ReumaCoV Brazil"-designed to monitor patients with immune-mediated rheumatologic disease (IMRD) during the SARS-CoV-2 pandemic. SLE adult patients with COVID-19 were compared with those without COVID-19. SLE activity was evaluated by the patient global assessment (PGA) and SLE Disease Activity Index 2000 (SLEDAI-2K). RESULTS: 604 SLE patients were included, 317 (52.4%) with COVID-19 and 287 (47.6%) in the control group. SLE COVID-19 patients reported a lower frequency of social isolation and worked more frequently as health professionals. There was no difference in the mean SLEDAI-2K score between groups in the post-COVID-19 period (5.8 [8.6] vs. 4.5 [8.0]; p = 0.190). However, infected patients reported increased SLE activity according to the Patient Global Assessment (PGA) during this period (2.9 [2.9] vs. 2.3 [2.6]; p = 0.031. Arterial hypertension (OR 2.48 [CI 95% 1.04-5.91], p = 0.041), cyclophosphamide (OR 14.32 [CI 95% 2.12-96.77], p = 0.006), dyspnea (OR: 7.10 [CI 95% 3.10-16.23], p < 0.001) and discontinuation of SLE treatment medication during infection (5.38 [CI 95% 1.97-15.48], p = 0.002), were independently associated with a higher chance of hospitalization related to COVID-19. Patients who received telemedicine support presented a 67% lower chance of hospitalization (OR 0.33 [CI 95% 0.12-0.88], p = 0.02). CONCLUSION: Hypertension and cyclophosphamide were associated with a severe outcome, and telemedicine can be a useful tool for SLE patients with COVID-19.

COVID-19 was not associated or trigger disease activity in spondylarthritis patients: ReumaCoV-Brasil cross-sectional data.

OBJECTIVES: To evaluate the disease activity before and after COVID-19 and risk factors associated with outcomes, including hospitalization, intensive care unit (ICU) admission, mechanical ventilation (MV) and death in patients with spondylarthritis (SpA). METHODS: ReumaCoV Brazil is a multicenter prospective cohort of immune-mediated rheumatic diseases (IMRD) patients with COVID-19 (case group), compared to a control group of IMRD patients without COVID-19. SpA patients enrolled were grouped as axial SpA (axSpA), psoriatic arthritis (PsA) and enteropathic arthritis, according to usual classification criteria. RESULTS: 353 SpA patients were included, of whom 229 (64.9%) were axSpA, 118 (33.4%) PsA and 6 enteropathic arthritis (1.7%). No significant difference was observed in disease activity before the study inclusion comparing cases and controls, as well no worsening of disease activity after COVID-19. The risk factors associated with hospitalization were age over 60 years (OR = 3.71; 95% CI 1.62-8.47, p = 0.001); one or more comorbidities (OR = 2.28; 95% CI 1.02-5.08, p = 0.001) and leflunomide treatment (OR = 4.46; 95% CI 1.33-24.9, p = 0.008). Not having comorbidities (OR = 0.11; 95% CI 0.02-0.50, p = 0.001) played a protective role for hospitalization. In multivariate analysis, leflunomide treatment (OR = 8.69; CI = 95% 1.41-53.64; p = 0.023) was associated with hospitalization; teleconsultation (OR = 0.14; CI = 95% 0.03-0.71; p = 0.01) and no comorbidities (OR = 0.14; CI = 95% 0.02-0.76; p = 0.02) remained at final model as protective factor. CONCLUSIONS: Our results showed no association between pre-COVID disease activity or that SARS-CoV-2 infection could trigger disease activity in patients with SpA. Teleconsultation and no comorbidities were associated with a lower hospitalization risk. Leflunomide remained significantly associated with higher risk of hospitalization after multiple adjustments.

Characteristics and Outcomes of People With Gout Hospitalized Due to COVID-19: Data From the COVID-19 Global Rheumatology Alliance Physician-Reported Registry.

OBJECTIVE: To describe people with gout who were diagnosed with coronavirus disease 2019 (COVID-19) and hospitalized and to characterize their outcomes. METHODS: Data on patients with gout hospitalized for COVID-19 between March 12, 2020, and October 25, 2021, were extracted from the COVID-19 Global Rheumatology Alliance registry. Descriptive statistics were used to describe the demographics, comorbidities, medication exposures, and COVID-19 outcomes including oxygenation or ventilation support and death. RESULTS: One hundred sixty-three patients with gout who developed COVID-19 and were hospitalized were included. The mean age was 63 years, and 85% were male. The majority of the group lived in the Western Pacific Region (35%) and North America (18%). Nearly half (46%) had two or more comorbidities, with hypertension (56%), cardiovascular disease (28%), diabetes mellitus (26%), chronic kidney disease (25%), and obesity (23%) being the most common. Glucocorticoids and colchicine were used pre-COVID-19 in 11% and 12% of the cohort, respectively. Over two thirds (68%) of the cohort required supplemental oxygen or ventilatory support during hospitalization. COVID-19-related death was reported in 16% of the overall cohort, with 73% of deaths documented in people with two or more comorbidities. CONCLUSION: This cohort of people with gout and COVID-19 who were hospitalized had high frequencies of ventilatory support and death. This suggests that patients with gout who were hospitalized for COVID-19 may be at risk of poor outcomes, perhaps related to known risk factors for poor outcomes, such as age and presence of comorbidity.

The effect of disease-modifying anti-rheumatic drugs on skeletal muscle mass in rheumatoid arthritis patients: a systematic review with meta-analysis.

INTRODUCTION: Rheumatoid arthritis (RA) is an autoimmune disease, characterized by chronic and systemic inflammation. Besides, it is known that RA patients may present several comorbidities, such as sarcopenia, a condition where patients present both muscle mass and muscle quality impairment. RA treatment is mostly pharmacological and consists in controlling systemic inflammation and disease activity. Despite that, the effect of pharmacological treatment on sarcopenia is not well characterized. OBJECTIVE: To summarize the effects of disease-modifying anti-rheumatic drugs (DMARDs) on skeletal muscle tissue in rheumatoid arthritis (RA) patients. METHODS: A systematic review of randomized clinical trials and observational studies was conducted using MEDLINE, Embase, Cochrane Library, and Web of Science. We selected studies with rheumatoid arthritis patients treated with disease-modifying anti-rheumatic drugs (DMARDs) that analyzed muscle mass parameters such as lean mass and appendicular lean mass. Methodological quality was assessed using the Newcastle-Ottawa Quality Assessment Scale. Standardized mean difference (SMD) and 95% confidence intervals (CI) were set. A meta-analysis of observational studies was performed using the R software, and we considered significant statistics when p < 0.05. RESULTS: Nine studies were included in this systematic review. In the meta-analysis, DMARD treatment had no positive difference (p = 0.60) in lean mass. In the same way, in the appendicular lean mass parameter, our results showed that DMARDs did not have changes between baseline and post-treatment analysis (p = 0.93). CONCLUSION: There is no evidence of a significant effect of DMARD therapy, either synthetic or biological, on muscle mass. However, this association should be investigated with more studies.

Incidence and risk factors for moderate/severe COVID-19 in rheumatic diseases patients on hydroxychloroquine: a 24-week prospective cohort.

OBJECTIVES: To evaluate the incidence of COVID-19 and its main outcomes in rheumatic disease (RD) patients on hydroxychloroquine (HCQ) compared to household cohabitants (HC). METHODS: This is a 24-week nationwide prospective multi-centre cohort with a control group without RD and not using HCQ. All participants were monitored through scheduled phone interviews performed by health professionals. Details regarding COVID-19 symptoms, and epidemiological, clinical, and demographic data were recorded on a specific web-based platform. COVID-19 was defined according to the Brazilian Ministry of Health criteria and classified as mild, moderate or severe. RESULTS: A total of 9,585 participants, 5,164 (53.9%) RD patients on HCQ and 4,421 (46.1%) HC were enrolled from March 29th, 2020 to September 30th, 2020, according to the eligibility criteria. COVID-19 confirmed cases were higher in RD patients than in cohabitants [728 (14.1%) vs. 427 (9.7%), p<0.001] in a 24-week follow-up. However, there was no significant difference regarding outcomes related to moderate/ severe COVID-19 (7.1% and 7.3%, respectively, p=0.896). After multiple adjustments, risk factors associated with hospitalisation were age over 65 (HR=4.5; 95%CI 1.35-15.04, p=0.014) and cardiopathy (HR=2.57; 95%CI 1.12-5.91, p=0.026). The final survival analysis demonstrated the probability of dying in 180 days after a COVID-19 diagnosis was significantly higher in patients over 65 years (HR=20.8; 95%CI 4.5-96.1) and with 2 or more comorbidities (HR=10.8; 95%CI 1.1-107.9 and HR=24.8; 95%CI 2.5-249.3, p=0.006, respectively). CONCLUSIONS: Although RD patients have had a higher COVID-19 incidence than individuals from the same epidemiological background, the COVID-19 severity was related to traditional risk factors, particularly multiple comorbidities and age, and not to underlying RD and HCQ.

Metabolomic Biomarker Candidates for Skeletal Muscle Loss in the Collagen-Induced Arthritis (CIA) Model.

There is no consensus for diagnosis or treatment of RA muscle loss. We aimed to investigate metabolites in arthritic mice urine as biomarkers of muscle loss. DBA1/J mice comprised collagen-induced arthritis (CIA) and control (CO) groups. Urine samples were collected at 0, 18, 35, 45, 55, and 65 days of disease and subjected to nuclear magnetic resonance spectroscopy. Metabolites were identified using Chenomx and Birmingham Metabolite libraries. The statistical model used principal component analysis, partial least-squares discriminant analysis, and partial least-squares regression analysis. Linear regression and Fisher's exact test via the MetaboAnalyst website were performed (VIP-score). Nearly 100 identified metabolites had CIA vs. CO and disease time-dependent differences (p < 0.05). Twenty-eight metabolites were muscle-associated: carnosine (VIPs 2.8 × 102) and succinyl acetone (VIPs 1.0 × 10) showed high importance in CIA vs. CO models at day 65; CIA pair analysis showed histidine (VIPs 1.2 × 102) days 55 vs. 65, histamine (VIPs 1.1 × 102) days 55 vs. 65, and L-methionine (VIPs 1.1 × 102) days 0 vs. 18. Carnosine was fatigue- (0.039) related, creatine was food intake- (-0.177) and body weight- (-0.039) related, and both metabolites were clinical score- (0.093; 0.050) and paw edema- (0.125; 0.026) related. Therefore, muscle metabolic alterations were detected in arthritic mice urine, enabling further validation in RA patient's urine, targeting prognosis, diagnosis, and monitoring of RA-mediated muscle loss.

Open-label phase 3 study of intravenous golimumab in patients with polyarticular juvenile idiopathic arthritis.

OBJECTIVES: To assess efficacy, pharmacokinetics (PK) and safety of intravenous (i.v.) golimumab in patients with polyarticular-course JIA (pc-JIA). METHODS: Children aged 2 to <18 years with active pc-JIA despite MTX therapy for ≥2 months received 80 mg/m2 golimumab at weeks 0, 4, then every 8 weeks through week 52 plus MTX weekly through week 28. The primary and major secondary endpoints were PK exposure and model-predicted steady-state area under the curve (AUCss) over an 8-week dosing interval at weeks 28 and 52, respectively. JIA ACR response and safety were also assessed. RESULTS: In total, 127 children were treated with i.v. golimumab. JIA ACR 30, 50, 70, and 90 response rates were 84%, 80%, 70% and 47%, respectively, at week 28 and were maintained through week 52. Golimumab serum concentrations and AUCss were 0.40 µg/ml and 399 µg ⋅ day/ml at week 28. PK exposure was maintained at week 52. Steady-state trough golimumab concentrations and AUCss were consistent across age categories and comparable to i.v. golimumab dosed 2 mg/kg in adults with rheumatoid arthritis. Golimumab antibodies and neutralizing antibodies were detected via a highly sensitive drug-tolerant assay in 31% (39/125) and 19% (24/125) of patients, respectively. Median trough golimumab concentration was lower in antibody-positive vs antibody-negative patients. Serious infections were reported in 6% of patients, including one death due to septic shock. CONCLUSION: Body surface area-based dosing of i.v. golimumab was well tolerated and provided adequate PK exposure for clinical efficacy in paediatric patients with active pc-JIA.ClinicalTrials.gov number NCT02277444.

Efficacy and Safety of Tocilizumab for Polyarticular-Course Juvenile Idiopathic Arthritis in the Open-Label Two-Year Extension of a Phase III Trial.

OBJECTIVE: To report the 2-year efficacy and safety of tocilizumab (TCZ) in patients with polyarticular-course juvenile idiopathic arthritis (JIA). METHODS: Patients ages 2-17 years with active polyarticular-course JIA, in whom treatment with methotrexate was unsuccessful, received 16 weeks of open-label intravenous TCZ in part 1 (once every 4 weeks: 8 mg/kg or 10 mg/kg for body weight [BW] <30 kg; 8 mg/kg for BW ≥30 kg). Assessments were based on the JIA-American College of Rheumatology (ACR) response (defined as percentage of improvement in ≥3 of the 6 JIA core response variables [CRVs]). Patients with at least a JIA-ACR30 response (defined as ≥30% improvement in ≥3 of the 6 JIA CRVs without worsening in >1 of the remaining JIA CRVs by >30%) at week 16 were randomly assigned (1:1) to receive TCZ or placebo in part 2. Patients remained in part 2 until either week 40 or the occurrence of JIA flare. Upon starting part 3, all patients received open-label TCZ. At week 104 of the study, efficacy was assessed using JIA-ACR50/70/90 response rates (defined as 50%, 70%, or 90% improvement, respectively), achievement of inactive disease, and the Juvenile Arthritis Disease Activity Score in 71 joints (JADAS-71). Safety was assessed in the all-exposure population per 100 patient-years of exposure. RESULTS: Overall, 188 patients entered part 1, 166 patients entered part 2, and 160 patients entered part 3. By week 104, among the 188 patients in the modified intent-to-treat group who received TCZ, JIA-ACR50/70/90 response rates were 80.3%/77.1%/59.6%, respectively, the median JADAS-71 score decreased from 3.6 at week 40 to 0.7 at week 104, 51.1% of patients had achieved inactive disease, and 31 of 66 patients who had been receiving glucocorticoids discontinued them. Adverse event (AE) and serious AE rates were 406.5 per 100 patient-years and 11.1 per 100 patient-years, respectively. The infection rate was 151.4 per 100 patient-years, and the serious infection rate was 5.2 per 100 patient-years. CONCLUSION: Patients treated with TCZ for polyarticular-course JIA showed high-level disease control for up to 2 years. The TCZ safety profile was consistent with that previously reported.

High Levels of Polypharmacy in Rheumatoid Arthritis-A Challenge Not Covered by Current Management Recommendations: Data From a Large Real-Life Study.

BACKGROUND: Rheumatoid arthritis (RA) is associated with high frequency of comorbidities and increased risk of polypharmacy. Although there is a great potential for complications, there is a gap in literature on polypharmacy in patients with rheumatic arthritis. OBJECTIVE: To evaluate the prevalence and factors associated with polypharmacy in a population in a real-life setting. METHODS: A cross-sectional multicenter study was conducted in Brazil. Patients underwent clinical evaluation and medical records analysis. Polypharmacy was considered as a dependent variable. To test independent variables, we used Poisson regression. RESULTS: We evaluated 792 patients (89% female, median age 56.6 years). Median duration of disease was 12.7 years, 78.73% had a positive rheumatoid factor. The median of disease activity score-28 was 3.5 (disease with mild activity), median of the clinical disease activity index score was 9, and median of health assessment questionnaire-disability index was 0.875; 47% used corticosteroids, 9.1% used nonsteroidal anti-inflammatory drugs, 90.9% used synthetic disease-modifying antirheumatic drugs, 35.7% used biologic disease-modifying antirheumatic drugs (DMARDs). In total, 537 (67.9%) patients used 5 or more drugs. Polypharmacy showed a relationship with a number of comorbidities and use of specific drugs (corticosteroids, methotrexate, and biological DMARDs). CONCLUSION: We found a high prevalence of polypharmacy (67.9%) in RA. Solutions to management this problem should be stimulated.

Upadacitinib monotherapy versus methotrexate monotherapy in methotrexate-naïve Japanese patients with rheumatoid arthritis: a sub-analysis of the Phase 3 SELECT-EARLY study.

OBJECTIVE: To assess upadacitinib monotherapy versus methotrexate (MTX) in MTX-naïve Japanese patients with rheumatoid arthritis (RA) from the Phase 3 SELECT-EARLY study. METHODS: Japanese patients were randomized 2:1:1:1 to upadacitinib 7.5, 15, or 30 mg daily or MTX 7.5 mg/week (titrated to ≤15 mg/week). Efficacy endpoints included the proportion of patients reporting 20% improvement in American College of Rheumatology criteria (ACR20) at week 12 and change from baseline in modified Total Sharp Score (mTSS) at week 24. Other efficacy outcomes were also assessed at weeks 12 and/or 24. Safety was assessed over 24 weeks. RESULTS: Of 138 Japanese patients enrolled, significantly more patients treated with upadacitinib 7.5 and 15 mg, but not 30 mg, reported ACR20 responses versus MTX at week 12. Significantly smaller changes from baseline in mTSS were observed with upadacitinib 15 and 30 mg, but not 7.5 mg, versus MTX at week 24. Upadacitinib demonstrated an acceptable safety profile; herpes zoster occurred in 3.6%, 7.4%, and 7.1% of patients treated with upadacitinib 7.5, 15, and 30 mg, respectively. CONCLUSION: Similar to the global study population, upadacitinib demonstrated clinical efficacy superior to placebo in the Japanese subpopulation. Among upadacitinib-treated patients, herpes zoster was least common with 7.5 mg.

Trial of Upadacitinib or Abatacept in Rheumatoid Arthritis.

BACKGROUND: Upadacitinib is an oral selective Janus kinase inhibitor to treat rheumatoid arthritis. The efficacy and safety of upadacitinib as compared with abatacept, a T-cell costimulation modulator, in patients with rheumatoid arthritis refractory to biologic disease-modifying antirheumatic drugs (DMARDs) are unclear. METHODS: In this 24-week, phase 3, double-blind, controlled trial, we randomly assigned patients in a 1:1 ratio to receive oral upadacitinib (15 mg once daily) or intravenous abatacept, each in combination with stable synthetic DMARDs. The primary end point was the change from baseline in the composite Disease Activity Score for 28 joints based on the C-reactive protein level (DAS28-CRP; range, 0 to 9.4, with higher scores indicating more disease activity) at week 12, assessed for noninferiority. Key secondary end points at week 12 were the superiority of upadacitinib over abatacept in the change from baseline in the DAS28-CRP and the percentage of patients having clinical remission according to a DAS28-CRP of less than 2.6. RESULTS: A total of 303 patients received upadacitinib, and 309 patients received abatacept. From baseline DAS28-CRP values of 5.70 in the upadacitinib group and 5.88 in the abatacept group, the mean change at week 12 was -2.52 and -2.00, respectively (difference, -0.52 points; 95% confidence interval [CI], -0.69 to -0.35; P<0.001 for noninferiority; P<0.001 for superiority). The percentage of patients having remission was 30.0% with upadacitinib and 13.3% with abatacept (difference, 16.8 percentage points; 95% CI, 10.4 to 23.2; P<0.001 for superiority). During the treatment period, one death, one nonfatal stroke, and two venous thromboembolic events occurred in the upadacitinib group, and more patients in the upadacitinib group than in the abatacept group had elevated hepatic aminotransferase levels. CONCLUSIONS: In patients with rheumatoid arthritis refractory to biologic DMARDs, upadacitinib was superior to abatacept in the change from baseline in the DAS28-CRP and the achievement of remission at week 12 but was associated with more serious adverse events. Longer and larger trials are required in order to determine the effect and safety of upadacitinib in patients with rheumatoid arthritis.
