Tocilizumab was efficacious in severe, persistent systemic JIA. Adverse events were common and included infection, neutropenia, and increased aminotransferase levels. (Funded by Hoffmann-La Roche; ClinicalTrials.gov number, NCT00642460.).
These two phase 3 studies show the efficacy of canakinumab in systemic JIA with active systemic features. (Funded by Novartis Pharma; ClinicalTrials.gov numbers, NCT00889863 and NCT00886769.).
ObjectiveTo evaluate the interleukin-6 receptor inhibitor tocilizumab for the treatment of patients with polyarticular-course juvenile idiopathic arthritis (pcJIA).MethodsThis three-part, randomised, placebo-controlled, double-blind withdrawal study (NCT00988221) included patients who had active pcJIA for ≥6 months and inadequate responses to methotrexate. During part 1, patients received open-label tocilizumab every 4 weeks (8 or 10 mg/kg for body weight (BW) <30 kg; 8 mg/kg for BW ≥30 kg). At week 16, patients with ≥JIA-American College of Rheumatology (ACR) 30 improvement entered the 24-week, double-blind part 2 after randomisation 1:1 to placebo or tocilizumab (stratified by methotrexate and steroid background therapy) for evaluation of the primary end point: JIA flare, compared with week 16. Patients flaring or completing part 2 received open-label tocilizumab.ResultsIn part 1, 188 patients received tocilizumab (<30 kg: 10 mg/kg (n=35) or 8 mg/kg (n=34); ≥30 kg: n=119). In part 2, 163 patients received tocilizumab (n=82) or placebo (n=81). JIA flare occurred in 48.1% of patients on placebo versus 25.6% continuing tocilizumab (difference in means adjusted for stratification: −0.21; 95% CI −0.35 to −0.08; p=0.0024). At the end of part 2, 64.6% and 45.1% of patients receiving tocilizumab had JIA-ACR70 and JIA-ACR90 responses, respectively. Rates/100 patient-years (PY) of adverse events (AEs) and serious AEs (SAEs) were 480 and 12.5, respectively; infections were the most common SAE (4.9/100 PY).ConclusionsTocilizumab treatment results in significant improvement, maintained over time, of pcJIA signs and symptoms and has a safety profile consistent with that for adults with rheumatoid arthritis.Trial registration number:NCT00988221.
Uveitis associated with juvenile idiopathic arthritis (JIA) typically involves the anterior chamber segment, follows an indolent chronic course, and presents a high rate of uveitic complications and a worse outcome as compared to other aetiologies of uveitis. Disease assessment, treatment, and outcome measures have not been standardized. Collaboration between pediatric rheumatologists and ophthalmologists is critical for effective management and prevention of morbidity, impaired vision, and irreparable visual loss. Although the Standardization of Uveitis Nomenclature Working Group recommendations have been a great advance to help clinicians to improve consistency in grading and reporting data, difficulties arise at the time of deciding the best treatment approach in the individual patient in routine daily practice. For this reason, recommendations for a systematized control and treatment strategies according to clinical characteristics and disease severity in children with JIA-related uveitis were developed by a panel of experts with special interest in uveitis associated with JIA. A clinical management algorithm organized in a stepwise regimen is here presented.
Cystoid macular edema (CME) is a leading cause of blindness. In this study we assessed the efficacy and safety of Tocilizumab (TCZ) in refractory CME. DESIGN: Retrospective case series. METHODS: Patients with CME secondary to non-infectious uveitis who had inadequate response to corticosteroids and at least one conventional immunosuppressive drug, and in most cases to other biological agents were studied. CME was defined as central retinal thickness greater than 300 µm. The primary outcome measure was macular thickness. Intraocular inflammation, best corrected visual acuity (BCVA), and corticosteroid-sparing effect were also analyzed. RESULTS: A total of 25 patients (mean± SD age 33.6±18.9 years; 17 women) with CME were assessed. Underlying diseases associated with uveitis-related CME are juvenile idiopathic arthritis (n=9), Behçet's disease (n=7), birdshot retinochoroidopathy (n=4), idiopathic (n=4), and sarcoidosis (n=1). The ocular patterns were panuveitis (n=9), anterior uveitis (n=7), posterior uveitis (n=5) and intermediate uveitis (n=4). Most patients had CME in both eyes (n=24). TCZ was used in monotherapy (n=11) or combined with conventional immunosuppressive drugs. Regardless of the underlying disease, compared to baseline, a statistically significant improvement in macular thickness (415.7±177.2 vs 259.1±499.5 microns; p=0.00009) and BCVA (0.39±0.31 vs 0.54±0.33; p =0.0002) was obtained, allowing us to reduce the daily dose of prednisone (15.9±13.6 mg/day vs 3.1±2.3 p=0.002) after 12 months of therapy. Remission was achieved in 14 patients. Only minor side effects were observed after a mean follow up of 12.7±8.34 months. CONCLUSION: Macular thickness is reduced following administration of TCZ in refractory uveitis-related CME.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
