Comparison of treatment response, remission rate and drug adherence in polyarticular juvenile idiopathic arthritis patients treated with etanercept, adalimumab or tocilizumab

Background Treatment response, remission rates and compliance in patients with polyarticular juvenile idiopathic arthritis (polyJIA) treated with adalimumab, etanercept, or tocilizumab were analyzed in clinical practice. Methods Data collected in the German BIKER registry were analyzed in patients with polyJIA who started treatment with approved biologics, adalimumab, etanercept or tocilizumab, from 2011 to 2015. Baseline patient characteristics, treatment response, safety and drug survival were compared. Results Two hundred thirty- six patient started adalimumab, 419 etanercept and 74 tocilizumab, with differences in baseline patient characteristics. Baseline Juvenile Disease Activity Score (JADAS)10 (mean ± SD) in the adalimumab/etanercept/tocilizumab cohorts was 12.1+/−7.6, 13.8 ± 7.1 and 15.1 ± 7.4, respectively (adalimumab vs etanercept, p = 0.01), and Childhood Health Assessment Questionnaire (CHAQ)-disability index scores was 0.43 ± 0.58, 0.59 ± 0.6 and 0.63 ± 0.55, respectively (adalimumab vs etanercept, p < 0.001). Uveitis history was more frequent in the adalimumab cohort (OR 5.73; p < 0.001). Balanced patients’ samples were obtained by a generalized propensity score to adjust for baseline differences. Pediatric ACR30/50/70/90 criterion improvement after 3 months treatment was achieved by 68%/60%/42%/24% in the etanercept cohort, 67%/59%/43%/27% in the adalimumab cohort and 61%/52%/35%/26% in the tocilizumab cohort. At 24 months, JADAS minimal disease activity was achieved in 52.4%/61.3%/52.4% and JADAS remission in 27.9%/34.8%/27.9% patients in the adalimumab/etanercept/tocilizumab cohorts, respectively. Etanercept was used in 95.5% of patients as a first biologic, adalimumab in 50.8% and tocilizumab in 20.2%. There were no important differences in efficacy between first-line and second-line use of biologics. In total 60.4%/49.4%/31.1% patients discontinued adalimumab/etanercept/tocilizumab, respectively (HR for adalimumab 1.67; p < 0.001; HR for tocilizumab 0.35; p = 0.001). Drug survival rates did not differ significantly in patients on biologic monotherapy compared with combination therapy with methotrexate. Over 4 years observation under etanercept/adalimumab/tocilizumab, 996/386/103 adverse events, and 148/119/26 serious adverse events, respectively, were reported. Conclusions In clinical practice, etanercept is most frequently used as first-line biologic. Adalimumab/etanercept/tocilizumab showed comparable efficacy toward polyJIA. Overall, tolerance was acceptable. Interestingly, compliance was highest with tocilizumab and lowest with adalimumab. This study provides the first indication for the comparison of different biologic agents in polyarticular JIA based on observational study data with all their weaknesses and demonstrates the need for well-controlled head-to-head studies for confirmation

Development of practice and consensus-based strategies including a treat-to-target approach for the management of moderate and severe juvenile dermatomyositis in Germany and Austria

Background: Juvenile dermatomyositis (JDM) is the most common inflammatory myopathy in childhood and a major cause of morbidity among children with pediatric rheumatic diseases. The management of JDM is very heterogeneous. The JDM working group of the Society for Pediatric Rheumatology (GKJR) aims to define consensus- and practice-based strategies in order to harmonize diagnosis, treatment and monitoring of JDM. Methods: The JDM working group was established in 2015 consisting of 23 pediatric rheumatologists, pediatric neurologists and dermatologists with expertise in the management of JDM. Current practice patterns of management in JDM had previously been identified via an online survey among pediatric rheumatologists and neurologists. Using a consensus process consisting of online surveys and a face-to-face consensus conference statements were defined regarding the diagnosis, treatment and monitoring of JDM. During the conference consensus was achieved via nominal group technique. Voting took place using an electronic audience response system, and at least 80% consensus was required for individual statements. Results: Overall 10 individual statements were developed, finally reaching a consensus of 92 to 100% regarding (1) establishing a diagnosis, (2) case definitions for the application of the strategies (moderate and severe JDM), (3) initial diagnostic testing, (4) monitoring and documentation, (5) treatment targets within the context of a treat-totarget strategy, (6) supportive therapies, (7) explicit definition of a treat-to-target strategy, (8) various glucocorticoid regimens, including intermittent intravenous methylprednisolone pulse and high-dose oral glucocorticoid therapies with tapering, (9) initial glucocorticoid-sparing therapy and (10) management of refractory disease. Conclusion: Using a consensus process among JDM experts, statements regarding the management of JDM were defined. These statements and the strategies aid in the management of patients with moderate and severe JDM

Long-term safety and effectiveness of canakinumab in patients with monogenic autoinflammatory diseases: results from the interim analysis of the RELIANCE registry

ObjectiveInterim analysis of the RELIANCE registry, an on-going, non-interventional, open-label, multicentre, prospective study evaluating the long-term safety, dosing regimens and effectiveness of canakinumab in patients with cryopyrin-associated periodic syndromes (CAPS), familial Mediterranean fever (FMF), tumour-necrosis factor receptor-associated periodic syndrome (TRAPS) or mevalonate-kinase deficiency (MKD)/hyperimmunoglobulin-D syndrome (HIDS).MethodsFrom September 2017 for patients with CAPS, and June 2018 for patients with FMF, TRAPS or MKD/HIDS, the registry enrolled paediatric (aged ≥2 years) and adult patients (aged ≥18 years) receiving canakinumab as part of their routine medical care. Safety, canakinumab dose, disease activity and quality of life outcome measures were evaluated at baseline and every 6 months until end of study visit.ResultsAt the analysis cut-off date (December 2020), 168 patients (91 CAPS, 54 FMF, 16 TRAPS and 7 MKD/HIDS) were enrolled. 85 (50.9%) patients were female and 72 (43.1%) were children (&lt;18 years). The median patient age was 20.0 years (range 2.0–79.0 years). In the CAPS cohort, serious infections and serious adverse drug-reactions were more common in patients receiving higher than the recommended starting dose (SD) of canakinumab. A trend to receive &gt;SD of canakinumab was observed in the pooled population. The majority of patients were reported as having either absent or mild/moderate disease activity (physician’s global assessment) from baseline to Month 30, with a stable proportion of patients (~70%) in remission under canakinumab treatment. Patient-reported disease activity (Visual Analogue Scale (VAS), Autoinflammatory Disease Activity Index), fatigue (VAS); markers of inflammation (C-reactive protein, serum amyloid A and erythrocyte sedimentation rate) remained well-controlled throughout.ConclusionData from this analysis confirm the long-term safety and effectiveness of canakinumab for the treatment of CAPS, FMF, TRAPS and MKD/HIDS.Novartis Pharma A

Protocols on classification, monitoring and therapy in children’s rheumatology (PRO-KIND): results of the working group Polyarticular juvenile idiopathic arthritis

Abstract Objective Several effective pharmacologic treatment options for polyarticual juvenile idiopathic arthritis (JIA) have emerged but initial treatment is heterogeneous in Germany. Therefore, the German Society of Pediatric Rheumatolgy has established a commission to develop consensus “Protocols on classification, monitoring and therapy in children's rheumatology (PRO-KIND)” to harmonize diagnostic and treatment approaches for new-onset JIA in Germany. Methods A set of definitions for in- and exclusion, diagnostic workup, parameters for the evaluation of disease activity criteria, therapeutic options, medication dosing, monitoring recommendations, targets, definitions of a therapy failure and four therapeutic algorithms developed by a working group were agreed by web based survey to which all members of the GKJR have been invited. A final protocol with 4 consensus treatment plans (CTP) was agreed in a face-to-face consensus conferences employing modified nominal group technique. Results The initial 17 definitions and recommendations for new-onset polyarticular JIA agreed by the working group reached >80% agreement in a web survey in 68 German paediatric rheumatologist. Four CTPs were developed based on treatment strategies for the first 12 months of therapy, as well as definitions for clinical and laboratory monitoring. The CTPs include a step-up plan (nonbiologic Disease-modifying antirheumatic drug [DMARD] followed by a biologic), a combination plan (combination of nonbiologic and biologic after failure of initial DMARD), an intensive pulse corticosteroid scheme in parallel with a DMARD followed by combination therapy and a multiple corticosteroids joint injections strategy in a treat to target approach. Step up will be guided by a treat to target strategy to reach a JADAS-improvement at month 3, acceptable disease at month 6 or 9 and JADAS remission or at least JADAS minimal disease activity at month 12. Conclusion Standardized baseline work-up, disease activity evaluation and a definition of a treat to target approach will result in better health outcomes for polyarticular JIA patients. Four CTPs were developed for new-onset polyarticular JIA, which coupled with data collection at defined intervals will be evaluated and improved to optimize management of polyarticular JIA. Harmonization of treatment will be the basis for future comparative effectiveness research

Comparative risk of infections among real-world users of biologics for juvenile idiopathic arthritis: data from the German BIKER registry

To examine whether treatment with interleukin (IL)-1-, IL-6-, tumour necrosis factor alpha (TNF alpha)-inhibitors or Abatacept is associated with an increased risk of common infections, infections requiring hospitalization (SAE) or opportunistic infections among real-world juvenile idiopathic arthritis (JIA) patients. Furthermore, the influence of other patient-related covariates on the occurrence of infections was investigated. Patients diagnosed with JIA and treated with biologics were selected from the German BIKER registry. Incidence rates (IR) of infections per 100 person years were calculated and compared between the different cohorts. Using multivariate logistic regression, odds ratios with 95% confidence intervals (CI) were determined for the influence of patient-related covariates (age, diagnosis, laboratory data, concomitant medication, JIA activity, comorbidities, and premedication) on the occurrence of infections. 3258 patients entered the analysis. A total of 3654 treatment episodes were distributed among TNF alpha- (Etanercept, Adalimumab, Golimumab, Infliximab, n = 3044), IL-1- (Anakinra, Canakinumab, n = 105), IL-6- (Tocilizumab, n = 400) and T-cell activation inhibitors (Abatacept, n = 105). 813 (22.2%) patients had at least one infection, 103 (2.8%) patients suffered from an SAE infection. Both common and SAE infections were significantly more frequent in IL-1 (IR 17.3, 95% CI 12.5/24 and IR 4.3, 95% CI 2.3/8.3) and IL-6 cohort (IR 16.7, 95% CI 13.9/20 and IR 2.8, 95% CI 1.8/4.4) compared to TNF alpha-inhibitor cohort (IR 8.7, 95% CI 8.1/9.4 and IR 1, 95% CI 0.8/1.3). When comparing the influencing factors for various infectious diseases, the use of corticosteroids, younger age, cardiac comorbidities and higher JIA-activity are the most striking risk factors. Relative to TNF alpha inhibitors and Abatacept, IL-1 and IL-6 inhibitors were associated with an increased risk of common and SAE infections. The influencing covariates identified may be helpful for the choice of a suitable biologic to treat JIA

Treat-to-target study for improved outcome in polyarticular juvenile idiopathic arthritis

Background Juvenile idiopathic arthritis is one of the most prevalent chronic inflammatory diseases in children. Evidence suggests that early effective treatment minimises the burden of disease during childhood and in further life. We hypothesise that a guided treat-to-target (T2T) approach is superior to routine care in polyarticular juvenile idiopathic arthritis (pJIA) in terms of reaching a clinical remission after 12 months of treatment. Methods Patients with early and active pJIA were enrolled. Targets for treatment were the following: Recognisable Juvenile Arthritis Disease Activity Score (JADAS) improvement after 3 months, acceptable disease at 6 months, minimal disease activity at 9 months and as primary endpoint remission after 12 months. Initially, patients received methotrexate. Failure to meet a defined target required treatment modification at the specified intervals. The choice of biologics was not influenced by the protocol. Finally, T2T patients were compared with a cohort of matched controls of patients with pJIA with unguided therapy documented by BIKER. Results Sixty-three patients were enrolled. Treatment targets after 3/6/9 and 12 months were reached by 73%/75%/77% and 48% of patients. Fifty-four patients completed the protocol. Compared with matched controls, on T2T guidance significantly more patients reached JADAS remission (48% vs 32%; OR 1.96 (1.1-3.7); p=0.033) and JADAS minimal disease activity (JADAS-MDA) (76% vs 59%; OR 2.2 (1.1-4.4); p=0.028). Patients from the T2T cohort received a biologic significantly more frequent (50% vs 9% after 12 months; OR 9.8 (4.6-20.8); p<0.0001). Conclusion The T2T concept was feasible and superior to unguided treatment. High rates of patients reached JADAS-MDA and JADA remission after 12 months. Approximately half of the patients achieved their therapy goals without a biologic

Experience with etanercept, tocilizumab and interleukin-1 inhibitors in systemic onset juvenile idiopathic arthritis patients from the BIKER registry

Abstract Background Treatment of systemic onset juvenile idiopathic arthritis JIA (sJIA), although dramatically improved, remains a challenge. Experience from clinical practice will be presented using data from the German Biologics register (BiKeR) for evaluation of efficacy and safety of treatment with etanercept (ETA), tocilizumab (TOC) and the interleukin-1 inhibitors anakinra and canakinumab (IL-1i) in sJIA. Methods Patients with sJIA documented in the BIKeR register, who were exposed to ETA, TOC or IL-1i were identified. Baseline demographics, clinical characteristics and disease activity parameters have been documented. Efficacy was determined using the JIA-American College of Rheumatology (ACR) response criteria and the Juvenile Disease Activity Score 10 (JADAS10). An intention-to-treat analysis was performed and patients who discontinued due to inefficacy or intolerance were analysed as non-responders. Safety assessments were based on adverse events (AEs) reports. Results Since 2000, 245 sJIA patients (50.3% male) exposed to biologic agents have been identified: 143 patients treated with ETA, 71 with TOC and 60 with IL-1i (anakinra 38, canakinumab 22). All patients received systemic steroids for pre-treatment but less frequently with TOC and IL-1i than with ETA for concomitant treatment. At baseline, the ETA cohort had fewer systemic disease manifestations but more active joints. The JIA-ACR 30/50/70/90 response over a period of 24 months was reached more often in the IL-1i and TOC cohort than with ETA. ETA/TOC/IL1i JADAS-remission (JADAS ≤1) was reached in 20%/37%/52%, minimal disease activity (JADAS ≤3.8 in 35%/61%/68% and ACR inactive disease in 24%/33%/56%). As compared to ETA, rates of AEs were significantly higher in the TOC cohort (risk ratio (RR) 5.3/patient-year; p < 0.0001) and serious AE were observed more frequently with TOC (RR 2.5; p < 0.5) and IL1i (2.9; p < 0.01). Conclusions A large proportion of patients gained significant response to treatment especially with TOC or IL-1is. After 6 months on treatment, JADAS remission was reached by up to half of patients while up to two thirds reached JADAS minimal disease activity. ETA has been used in the past but it is clearly less effective and its use in systemic JIA has markedly decreased in Germany
