How can trial designs better serve the needs of children and young people with juvenile idiopathic arthritis? THE LANCET. RHEUMATOLOGY 2024; 6:e648-e652. [PMID: 38552652 DOI: 10.1016/s2665-9913(24)00026-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 01/23/2024] [Accepted: 01/24/2024] [Indexed: 08/23/2024]
Abstract
In juvenile idiopathic arthritis we have seen remarkable progress in the number of available licensed biological and small molecule treatments in the past two decades, leading to improved outcomes for patients. Designing clinical trials for these therapeutics is fraught with ethical, legislative, and practical challenges. However, many aspects of current clinical trial design in juvenile idiopathic arthritis do not meet the needs of patients and clinicians. Commonly used withdrawal trial designs raise substantial ethical concerns for patients and families who believe that they do not enable evidence-based and patient-centred decisions around medication choices. In this Viewpoint, we present the personal views of a patient and parent network that is of the opinion that current trial design in juvenile idiopathic arthritis is failing children and young people with juvenile idiopathic arthritis and set out the need for change informed by lived experience.

Safety and efficacy of tofacitinib for the treatment of patients with juvenile idiopathic arthritis: preliminary results of an open-label, long-term extension study. Ann Rheum Dis 2024:ard-2023-225094. [PMID: 38849152 DOI: 10.1136/ard-2023-225094] [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: 10/03/2023] [Accepted: 05/22/2024] [Indexed: 06/09/2024]
Abstract
OBJECTIVES We report the safety, tolerability and efficacy of tofacitinib in patients with juvenile idiopathic arthritis (JIA) in an ongoing long-term extension (LTE) study. METHODS Patients (2-<18 years) with JIA who completed phase 1/3 index studies or discontinued for reasons excluding treatment-related serious adverse events (AEs) entered the LTE study and received tofacitinib 5 mg two times per day or equivalent weight-based doses. Safety outcomes included AEs, serious AEs and AEs of special interest. Efficacy outcomes included improvement since tofacitinib initiation per the JIA-American College of Rheumatology (ACR)70/90 criteria, JIA flare rate and disease activity measured by Juvenile Arthritis Disease Activity Score (JADAS)27, with inactive disease corresponding to JADAS ≤1.0. RESULTS Of 225 patients with JIA (median (range) duration of treatment, 41.6 (1-103) months), 201 (89.3%) had AEs; 34 (15.1%) had serious AEs. 10 patients developed serious infections; three had herpes zoster. Two patients newly developed uveitis. Among patients with polyarticular course JIA, JIA-ACR70/90 response rates were 60.0% (78 of 130) and 33.6% (47 of 140), respectively, at month 1, and generally improved over time. JIA flare events generally occurred in <5% of patients through to month 48. Observed mean (SE) JADAS27 was 22.0 (0.6) at baseline, 6.2 (0.7) at month 1 and 2.8 (0.5) at month 48, with inactive disease in 28.8% (36 of 125) of patients at month 1 and 46.8% (29 of 82) at month 48. CONCLUSIONS In this interim analysis of LTE study data in patients with JIA, safety findings were consistent with the known profile of tofacitinib, and efficacy was maintained up to month 48. TRIAL REGISTRATION NUMBER NCT01500551.

Abstract
PURPOSE OF REVIEW This review summarizes latest developments in treatment of juvenile spondyloarthritis (JSpA), specifically enthesitis-related arthritis (ERA) and juvenile psoriatic arthritis (JPsA). RECENT FINDINGS There has been addition of biologic disease modifying antirheumatic drugs (bDMARDs) beyond tumor necrosis factor inhibitors (TNFi) for JSpA such as IL-17 blockers, IL-23 blockers, and janus activating kinase inhibitors with favorable safety profile. Conducting robust clinical trials for this subpopulation of JIA remains a challenge; extrapolation studies are being used to obtain approval from regulatory agencies. SUMMARY Newer drug therapies have expanded the scope of treatment for patients with JSpA. bDMARDs such as adalimumab, etanercept, infliximab, and secukinumab have demonstrated clinically significant treatment efficacy in ERA and JPsA. Based on extrapolation studies, intravenous golimumab, etanercept, abatacept, and ustekinumab have gained Food and Drug Administration (FDA) approval for JPsA. Long-term follow-up studies continue to demonstrate acceptable safety profiles. There is need for more real-world data on drug efficacy from Registry studies and research on effective de-escalation strategies.

Rheumatology (Oxford) 2024; 63:594-607.

Abstract
Biologic and targeted synthetic DMARDs (b/tsDMARDs) have revolutionized the management of multiple rheumatic inflammatory conditions. Among these, polyarticular JIA (pJIA) and RA display similarities in terms of disease pathophysiology and response pattern to b/tsDMARDs. Indeed, the therapeutic efficacy of novel targeted drugs is variable among individual patients, in both RA and pJIA. The mechanisms and determinants of this heterogeneous response are diverse and complex, such that the development of true 'precision'-medicine strategies has proven highly challenging. In this review, we will discuss pathophysiological, patient-specific, drug-specific and environmental factors contributing to individual therapeutic response in pJIA in comparison with what is known in RA. Although some biomarkers have been identified that stratify with respect to the likelihood of either therapeutic response or non-response, few have proved useful in clinical practice so far, likely due to the complexity of treatment-response mechanisms. Consequently, we propose a pragmatic, patient-centred and clinically based approach, i.e. personalized instead of biomarker-based precision medicine in JIA.

Abstract
INTRODUCTION The management of refractory juvenile idiopathic associated uveitis (JIAU) or childhood-onset chronic anterior uveitis (CAU) is a challenge. There is no clear consensus or evidence base for to suggest the most appropriate therapy after primary or secondary failure of biweekly adalimumab. In this scenario, most clinicians advocate switching to another anti-tumor necrosis factor alpha inhibitor; however, there are a variety of other disease modifying agents to choose from albeit with a differing levels of evidence. AREAS COVERED We discuss how to define nonresponse and potential treatment options for patients with JIAU and CAU refractory to biweekly adalimumab. EXPERT OPINION Uncontrolled CAU and JIAU remain one of the most challenging diseases to manage and can lead to irreversible loss of vision in a third of those affected. Amongst the possible choices, weekly adalimumab, infliximab, tocilizumab and abatacept have more evidence to support their use. JAK inhibitors seem to be a promising option. Golimumab and Rituximab has also been thought to be partially effective in some refractory cases, whereas IL-17, IL-23, and IL-12 inhibition along with apremilast seem not to be a therapeutic option currently. The route of administration should also be considered as there can be significant pros and cons for different children.

Efficacy and safety of golimumab in patients with non-radiographic axial spondyloarthritis: a withdrawal and retreatment study (GO-BACK). Rheumatology (Oxford) 2023; 62:3601-3609. [PMID: 36919768 PMCID: PMC10629786 DOI: 10.1093/rheumatology/kead112] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 02/23/2023] [Accepted: 03/01/2023] [Indexed: 03/16/2023] Open
Abstract
OBJECTIVES The GO-BACK study was designed to evaluate the efficacy and safety of golimumab (GLM) treatment withdrawal in adults with non-radiographic axial spondyloarthritis (nr-axSpA) who demonstrate inactive disease during a 10-month open-label (OL) GLM run-in. METHODS Eligible participants received OL GLM in period 1. In period 2, participants who achieved inactive disease were randomized 1:1:1 to receive double-blind (DB) treatment with monthly placebo (PBO, treatment withdrawal) or continued GLM treatment given monthly (GLM QMT) or every 2 months (GLM Q2MT). Participants who did not have a disease flare continued DB treatment for ∼12 months. Participants with a disease flare discontinued DB treatment and resumed monthly OL GLM. Primary endpoint compared the proportion of participants without a disease flare in the continued GLM treatment groups (QMT or Q2MT) vs PBO in a multiplicity-controlled, step-down fashion. Safety follow-up continued for ∼3 months after last treatment. RESULTS A total of 188 patients, out of the 323 enrolled, were eligible for participation in period 2. Both GLM QMT and GLM Q2MT were superior to treatment withdrawal (PBO) in preventing disease flare (P < 0.001), with a treatment-difference vs PBO of 50.4% and 34.4% for the GLM QMT and GLM Q2MT groups, respectively. The time-to-first flare was significantly longer (log-rank P < 0.0001) with GLM treatment compared with PBO. Of 53 participants (in Q2MT or PBO) who had a confirmed disease flare, 51 (96.2%) attained a clinical response within 3 months of restarting OL GLM. Adverse events were consistent with the known GLM safety profile. CONCLUSION Among participants with active nr-axSpA who attained inactive disease after 10 months of GLM treatment, continued GLM treatment is well tolerated and provides superior protection against disease flares compared with GLM withdrawal.

Abstract
Enthesitis-related arthritis (ERA) represents 5-30% of all cases of juvenile idiopathic arthritis (JIA) and belongs to the spectrum of the disorders included in the group of juvenile spondyloarthritis. In the last decade, there have been considerable advances in the classification, diagnosis, monitoring, and treatment of ERA. New provisional criteria for ERA have been recently proposed by the Paediatric Rheumatology INternational Trials Organisation, as part of a wider revision of the International League of Associations for Rheumatology criteria for JIA. The increased use of magnetic resonance imaging has shown that a high proportion of patients with ERA present a subclinical axial disease. Diverse instruments can be used to assess the disease activity of ERA. The therapeutic recommendations for ERA are comparable to those applied to other non-systemic JIA categories, unless axial disease and/or enthesitis are present. In such cases, the early use of a TNF-alpha inhibitor is recommended. Novel treatment agents are promising, including IL-17/IL-23 or JAK/STAT pathways blockers.

Abstract
OBJECTIVE Stakeholders met to address persistent challenges facing the development of therapeutics for polyarticular juvenile idiopathic arthritis (pJIA), which result in fewer approved therapies for children with pJIA than adults with rheumatoid arthritis (RA) and long lag times from adult RA approval to pediatric labeling. Ensuring that new medications are authorized in a timely manner to meet the needs of JIA patients worldwide is critically important to multiple stakeholders. METHODS The Food and Drug Administration in collaboration with the University of Maryland Center for Regulatory Science and Innovation held a public workshop entitled "Accelerating Drug Development for pJIA" on October 2, 2019, to address challenges surrounding access to new medications for children and adolescents with pJIA. Regulatory, academic, and industry stakeholders, as well as patient representatives, participated in the workshop, which consisted of 4 sessions, including panel discussions. RESULTS The workshop facilitated broad public discussion of challenges facing the development of pJIA therapeutics, highlighting areas of need and outlining opportunities to expedite development, while underscoring the necessity of close collaboration between all stakeholders, including patients and families. CONCLUSION This report summarizes key aspects of the workshop, including the appropriate application of innovative approaches to the development of pJIA therapeutics, including extrapolation, to address current challenges and provide timely access to newer safe and effective treatments. Long-term safety assessment is of pressing concern to stakeholders and cannot be fully extrapolated from adult studies but requires consistent postmarketing long-term follow-up.

Baricitinib in juvenile idiopathic arthritis: an international, phase 3, randomised, double-blind, placebo-controlled, withdrawal, efficacy, and safety trial. Lancet 2023; 402:555-570.

Abstract
BACKGROUND Juvenile idiopathic arthritis can be refractory to some or all treatment regimens, therefore new medications are needed to treat this population. This trial assessed the efficacy and safety of baricitinib, an oral Janus kinase 1/2-selective inhibitor, versus placebo in patients with juvenile idiopathic arthritis. METHODS This phase 3, randomised, double-blind, placebo-controlled, withdrawal, efficacy, and safety trial was conducted in 75 centres in 20 countries. We enrolled patients (aged 2 to <18 years) with polyarticular juvenile idiopathic arthritis (positive or negative for rheumatoid factor), extended oligoarticular juvenile idiopathic arthritis, enthesitis-related arthritis, or juvenile psoriatic arthritis, and an inadequate response (after ≥12 weeks of treatment) or intolerance to one or more conventional synthetic or biologic disease-modifying antirheumatic drugs (DMARDs). The trial consisted of a 2-week safety and pharmacokinetic period, a 12-week open-label lead-in period (10 weeks for the safety and pharmacokinetic subcohort), and an up to 32-week placebo-controlled double-blind withdrawal period. After age-based dosing was established in the safety and pharmacokinetic period, patients received a once-daily 4 mg adult-equivalent dose of baricitinib (tablets or suspension) in the open-label lead-in period. Patients meeting Juvenile Idiopathic Arthritis-American College of Rheumatology (JIA-ACR) 30 criteria (JIA-ACR30 responders) at the end of the open-label lead-in (week 12) were eligible for random assignment (1:1) to receive placebo or continue receiving baricitinib, and remained in the double-blind withdrawal period until disease flare or up to the end of the double-blind withdrawal period (week 44). Patients and any personnel interacting directly with patients or sites were masked to group assignment. The primary endpoint was time to disease flare during the double-blind withdrawal period and was assessed in the intention-to-treat population of all randomly assigned patients. Safety was assessed in all patients who received at least one dose of baricitinib throughout the three trial periods. For adverse events in the double-blind withdrawal period, exposure-adjusted incidence rates were calculated. The trial was registered on ClinicalTrials.gov, NCT03773978, and is completed. FINDINGS Between Dec 17, 2018 and March 3, 2021, 220 patients were enrolled and received at least one dose of baricitinib (152 [69%] girls and 68 [31%] boys; median age 14·0 years [IQR 12·0-16·0]). 219 patients received baricitinib in the open-label lead-in period, of whom 163 (74%) had at least a JIA-ACR30 response at week 12 and were randomly assigned to placebo (n=81) or baricitinib (n=82) in the double-blind withdrawal period. Time to disease flare was significantly shorter with placebo versus baricitinib (hazard ratio 0·241 [95% CI 0·128-0·453], p<0·0001). Median time to flare was 27·14 weeks (95% CI 15·29-not estimable) in the placebo group, and not evaluable for patients in the baricitinib group (<50% had a flare event). Six (3%) of 220 patients had serious adverse events during the safety and pharmacokinetic period or open-label lead-in period. In the double-blind withdrawal period, serious adverse events were reported in four (5%) of 82 patients (incidence rate [IR] 9·7 [95% CI 2·7-24·9] per 100 patient-years at risk) in the baricitinib group and three (4%) of 81 (IR 10·2 [2·1-29·7]) in the placebo group. Treatment-emergent infections were reported during the safety and pharmacokinetic or open-label lead-in period in 55 (25%) of 220 patients, and during the double-blind withdrawal period in 31 (38%) of 82 (IR 102·1 [95% CI 69·3-144·9]) in the baricitinib group and 15 (19%) of 81 (IR 59·0 [33·0-97·3]) in the placebo group. Pulmonary embolism was reported as a serious adverse event in one patient (1%; IR 2·4 [95% CI 0·1-13·3]) in the baricitinib group in the double-blind withdrawal period, which was judged to be related to study treatment. INTERPRETATION Baricitinib was efficacious with an acceptable safety profile in the treatment of polyarticular juvenile idiopathic arthritis, extended oligoarticular juvenile idiopathic arthritis, enthesitis-related arthritis, and juvenile psoriatic arthritis, after inadequate response or intolerance to standard therapy.

Golimumab for Polyarticular Juvenile Idiopathic Arthritis and Psoriatic Arthritis: Pharmacologic and Clinical Considerations. Life (Basel) 2023; 13:1601. [PMID: 37511975 PMCID: PMC10381137 DOI: 10.3390/life13071601] [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: 06/05/2023] [Revised: 07/20/2023] [Accepted: 07/20/2023] [Indexed: 07/30/2023] Open
Abstract
Psoriatic arthritis is a chronic debilitating autoimmune condition, and when diagnosed in patients before the age of eighteen, it is considered pediatric polyarticular juvenile idiopathic arthritis. Monoarticular or polyarticular psoriatic arthritis can be distinguished from other arthropathies by its unique cutaneous manifestations. With numerous treatments already in clinical practice, there are numerous options for treatment. The current literature indicates an elevated level of tumor necrosis factor is present in the epidermis of patients with psoriatic arthritis when compared with the general population. For this reason, anti-tumor necrosis factor therapies have become a hallmark option for psoriatic arthritis patients. Golimumab, a human monoclonal antibody tumor necrosis factor-alpha (TNF-a) receptor antagonist, was chosen as the focus therapy for this investigation. The mechanism of action behind anti-tumor necrosis factor-alpha blockers involves the binding of human TNF-a soluble and transmembrane proteins to competitively inhibit TNF-a from binding to its cellular receptors. The present investigation evaluated current treatment options available for both juvenile- and adult-onset psoriatic arthritis and compared them with the efficacy seen with golimumab use. Pediatric patients included children ages 2-17, while adult populations included adults 18-83 years old. The Food and Drug Administration has approved golimumab for the treatment of rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, ulcerative colitis, and polyarticular juvenile idiopathic arthritis. The results of four different studies reporting on the therapeutic effects and adverse events of golimumab use in psoriatic arthritis, juvenile psoriatic arthritis, juvenile idiopathic arthritis, and juvenile polyarticular arthritis were used for comparison. The meta-analysis referenced studies including children ages 2-17 with no reference mentioning children less than age 2. Based on the results of each study, it can be concluded that golimumab, a human monoclonal antibody that prevents the activation of cellular inflammatory reactions when it binds to the TNF-a receptor, is an effective option for patients with active psoriatic arthritis and psoriatic juvenile idiopathic arthritis and for patients who are no longer responding to their current treatment with adalimumab. Each study also reported minimal adverse events associated with golimumab use, and the drug can be safely used in the pediatric population.

Abstract
INTRODUCTION Juvenile idiopathic arthritis is the most common chronic rheumatologic disease in children. Uveitis is the most common extra-articular manifestation of JIA, and it can be a sight-threatening condition. AREAS COVERED In this review article, we discussed epidemiology, risk factors, clinical presentation, supportive laboratory tests, treatment options, and complications of Juvenile idiopathic arthritis and Juvenile idiopathic arthritis associated uveitis. We covered conventional immunomodulatory therapy and biologic response modifiers agents for different types of Juvenile idiopathic arthritis and their associated uveitis. Finally, we discussed the course of disease, functional outcome, and the quality of life of Juvenile idiopathic arthritis and Juvenile idiopathic arthritis-associated uveitis. EXPERT OPINION Although clinical outcomes of Juvenile idiopathic arthritis and its associated uveitis have been improved over the past three decades by biologic response modifier agents, a significant proportion of patients require active treatment into adult life therefore screening and monitoring of these patients is required during the patient's entire life. The limited number of food and drug administration approved biologic response modifier agents for the treatment of Juvenile idiopathic arthritis associated uveitis justify more randomized clinical trials with new medications in this field.

Abstract
OBJECTIVE A systematic literature review was conducted to summarize efficacy and safety data from studies that evaluated tumor necrosis factor inhibitors in patients with juvenile idiopathic arthritis (JIA). METHODS Relevant publications were identified via online searches (cutoff: March 16, 2021). After screening search results, outcome data were extracted if the treatment arm included ≥ 30 patients. Outcomes were described narratively, with efficacy assessed by JIA-American College of Rheumatology (ACR) response criteria and safety assessed by the incidence of serious adverse events (SAEs) per 100 patient-years (100PY). RESULTS Among 87 relevant publications included in the qualitative synthesis, 19 publications described 13 clinical trials. Across the 13 trials, the percentages of patients who achieved JIA-ACR30/50/70/90 responses at Week 12 with adalimumab ranged 71-94%, 68-90%, 55-61%, and 39-42%, respectively; with etanercept (Week 12), 73-94%, 53-78%, 36-59%, and 28%; with golimumab (Week 16), 89%, 79%, 66%, and 36%; and with infliximab (Week 14), 64%, 50%, and 22% (JIA-ACR90 not reported). SAE incidence across all time points ranged 0-13.7 SAE/100PY for adalimumab, 0-20.0 SAE/100PY for etanercept, and 10.4-24.3 SAE/100PY for golimumab (1 study). SAE incidence could not be estimated from the 2 infliximab publications. CONCLUSION Tumor necrosis factor inhibitors are effective and well tolerated in the treatment of JIA, but additional evidence from head-to-head studies and over longer periods of time, especially in the context of the transition from pediatric to adult care, would be useful.

Biologic Disease-Modifying and Other Anti-Rheumatic Drugs Use in Patients with Moderate-to-Severe Juvenile Idiopathic Arthritis Based on a Japanese Nationwide Claims Database. Ther Clin Risk Manag 2022; 18:843-853. [PMID: 36046102 PMCID: PMC9422327 DOI: 10.2147/tcrm.s375890] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Accepted: 08/08/2022] [Indexed: 11/25/2022] Open
Abstract
Purpose Biologic disease-modifying anti-rheumatic drugs (bDMARDs) are highly effective and safe against juvenile idiopathic arthritis (JIA), which is classified into systemic JIA (sJIA) and the other JIA categories (non-sJIA) according to differences in clinical symptoms and pathophysiology. The purpose of the current study was to investigate trends in patterns of prescribing bDMARDs for moderate-to-severe JIA using a relatively large sample size in Japan. Patients and Methods A descriptive epidemiological study based on a nationwide claims database in Japan was conducted from 2012 to 2018 using the “JMDC Claims Database” to explain annual changes based on the number of patients prescribed bDMARDs. Study drugs were identified based on the Anatomical Therapeutic Chemical codes, such as methotrexate, glucocorticoids, non-steroidal anti-inflammatory drugs, and bDMARDs. Results From a database of 6,862,244 patients, the following exclusion criteria were applied: aged ≥16 years, without “M08” in their ICD-10 code as disease, and missing the information of prescription date in the database during the study period, resulting in a final number of 111 JIA patients. We found an increasing trend for adalimumab and tocilizumab and a decreasing trend for methotrexate. Differences in medication use between sJIA and non-sJIA patients were also evident, being consistent with national and international guidelines. Conclusion Although the introduction of bDMARDs has markedly improved the efficacy of JIA therapy, there are still many short- and long-term safety issues to be examined, including the risk of infection and potential risk of associated malignancy. Future studies are needed to clarify these issues.

Abstract
Juvenile idiopathic arthritis (JIA) is an umbrella term for arthritis of unknown origin, lasting for >6 weeks with onset before 16 years of age. JIA is the most common chronic inflammatory rheumatic condition of childhood. According to the International League Against Rheumatism (ILAR) classification, seven mutually exclusive categories of JIA exist based on disease manifestations during the first 6 months of disease. Although the ILAR classification has been useful to foster research, it has been criticized mainly as it does not distinguish those forms of chronic arthritis observed in adults and in children from those that may be unique to childhood. Hence, efforts to provide a new evidence-based classification are ongoing. Similar to arthritis observed in adults, pathogenesis involves autoimmune and autoinflammatory mechanisms. The field has witnessed a remarkable improvement in therapeutic possibilities of JIA owing to the availability of new potent drugs and the possibility to perform controlled trials with support from legislative interventions and large networks availability. The goal of drug therapy in JIA is to rapidly reduce disease activity to inactive disease or clinical remission, minimize drug side effects and achieve a quality of life comparable to that of healthy peers. As JIA can influence all aspects of a child's and their family's life, researchers increasingly recognize improvement of health-related quality of life as a key treatment goal.

Abstract
OBJECTIVES To describe the extrapolation approaches used to support intravenous (IV) golimumab for polyarticular juvenile idiopathic arthritis (pJIA) and juvenile psoriatic arthritis (jPsA) and subcutaneous (SC) ustekinumab for jPsA. METHODS Pharmacokinetic, clinical response, and safety data from trials of IV golimumab and SC ustekinumab in polyarticular-course JIA (pc-JIA) (GO-VIVA) or pediatric psoriasis (PsO) (CADMUS and CADMUS Jr) and data from pivotal, phase 3 trials of these agents in adults with similar diseases were used to support extrapolation in pJIA and jPsA. In the phase 3 GO-VIVA trial, patients with pc-JIA aged 2 to < 18 years received IV golimumab 80 mg/m2 at weeks 0, 4, then every 8 weeks (Q8W). In the phase 3, randomized, placebo-controlled CADMUS trial, patients with PsO aged ≥ 12 to < 18 years received ustekinumab at weeks 0, 4, then Q12W. In the phase 3 CADMUS Jr trial, patients with PsO aged ≥ 6 to < 12 years received ustekinumab at weeks 0, 4, then Q12W. The ustekinumab analyses used data only from patients who received the standard ustekinumab dosing regimen (≤ 60 kg: 0.75 mg/kg; > 60 to ≤ 100 kg: 45 mg; > 100 kg: 90 mg). RESULTS In the 127 patients with pc-JIA treated with IV golimumab (GO-VIVA), pharmacokinetic and exposure-response results were similar to those in adults with rheumatoid arthritis treated with IV golimumab. Additionally, pharmacokinetic and clinical response data from five patients with jPsA in GO-VIVA were comparable to those in adults with PsA treated with IV golimumab. No new safety signals were observed in GO-VIVA. Pharmacokinetic and clinical response data observed in the four pediatric patients with PsO and jPsA treated with ustekinumab in CADMUS and CADMUS Jr were similar to those in the 91 pediatric patients with PsO without jPsA in these trials and to those in adults with PsA treated with ustekinumab. Safety was extrapolated from CADMUS or CADMUS Jr; no new signals were observed. CONCLUSIONS These three sets of analyses corroborate similar exposure and efficacy of IV golimumab in pediatric patients with pc-JIA or jPsA and SC ustekinumab in patients with jPsA to support extrapolation of established adult efficacy. The overall safety profiles of IV golimumab in pediatric patients with pc-JIA or jPsA and SC ustekinumab in pediatric patients with PsO with or without jPsA were consistent with the safety profiles of these agents in the context of their clinical programs and cumulative use. Based on these analyses, the US Food and Drug Administration approved IV golimumab for polyarticular JIA and active PsA in patients 2 years and older and SC ustekinumab for pediatric PsA in patients 6 years and older, highlighting how use of an extrapolation approach can help streamline drug development for pediatric patient populations in whom larger clinical trials are not feasible. CLINICAL TRIAL REGISTRATION GO-VIVA (NCT02277444) was registered at clinicaltrials.gov on 29 October 2014; CADMUS (NCT01090427) was registered on 22 March 2010; and CADMUS Jr (NCT02698475) was registered on 3 March 2016.

Abstract
PURPOSE OF REVIEW Biologics and novel targeted therapeutics have transformed the management of pediatric rheumatic diseases over the past two decades; however, questions about short-term and long-term safety remain. Safety data gathered from recent clinical trials, long-term extensions of prior trials, registries, and other real-world evidence are summarized here for biologics and novel therapeutics commonly prescribed for pediatric rheumatic diseases. RECENT FINDINGS With nearly 20 years of therapeutic experience, tumor necrosis inhibitors (TNFi) are generally well tolerated, although infections, malignancy, and development of new autoimmunity remain a concern. Risk of infections may be higher in IL-1 and IL-6 inhibitors, and lower in abatacept, compared with TNFi. Safety data for B-cell-targeted therapeutics and janus kinase inhibitors are emerging, but remain limited, especially in children. SUMMARY Biologic and novel targeted therapeutics offer a promising future for children with pediatric rheumatic disease. However, long-term safety data in children remain limited for several agents. With any therapeutic option, both short-term and long-term safety concerns must be weighed against individual clinical needs when choosing the optimal treatment for each child.

Abstract
Monocytes (Mos) and macrophages (Mφs) are key players in the innate immune system and are critical in coordinating the initiation, expansion, and regression of many autoimmune diseases. In addition, they display immunoregulatory effects that impact inflammation and are essential in tissue repair and regeneration. Juvenile idiopathic arthritis (JIA) is an umbrella term describing inflammatory joint diseases in children. Accumulated evidence suggests a link between Mo and Mφ activation and JIA pathogenesis. Accordingly, topics regarding the signals and mechanisms regulating Mo and Mφ activation leading to pathologies in patients with JIA are of great interest. In this review, we critically summarize recent advances in the understanding of how Mo and Mφ activation is involved in JIA pathogenesis and focus on the signaling pathways and mechanisms participating in the related cell activation processes.
