Introduction: Tocilizumab (TCZ) is a humanized anti-interleukin-6 (IL-6) receptor monoclonal antibody that is widely used to treat rheumatic arthritis (RA). When initially introduced, TCZ was administered by intravenous infusion. Since 2013, subcutaneous administration of TCZ has also been offered. Currently, we can choose the TCZ administration route according to patient preference. Areas covered: We summarize TCZ therapy and review recent advances of TCZ-SC therapy. Initially, three pre-clinical phase III randomized controlled trials – MUSASHI, SUMMACTA, and BREVACTA – demonstrated the similar effectiveness and safety between subcutaneous TCZ (TCZ-SC) and intravenous TCZ (TCZ-IV). Several real-world TCZ-SC studies further confirmed these findings. These studies also focused on the influence of body weight. Since TCZ-SC is a fixed dose therapy, the efficacy of TCZ-SC 162 mg q2w was sometimes inadequate in high body weight patients. By contrast, TCZ-SC 162 mg qw therapy achieved a higher trough serum concentration of TCZ than TCZ-IV 8 mg/kg q4w. No additional safety concerns were noted. Finally, possible differences between the IL-6 inhibitor and IL-6 receptor inhibitor are discussed. Expert opinion: There are no appreciable differences between TCZ-SC and TCZ-IV in clinical practice. Thus, TCZ-SC is an attractive option for RA patients. 相似文献

目的研究类风湿关节炎(rheumatoidarthritis,RA)患者外周血中Th1、Th2和Th17细胞亚群表达比例变化,分析RA免疫学发病机制。方法运用流式细胞术检测RA患者及对照组外周血单个核细胞(PBMCs)中Th1、Th2、Th17细胞表达比例。并用酶联免疫吸附法检测RA患者及对照组血清中IFN-γ、IL-4、IL-17的浓度。结果RA患者CD4+T细胞明显高于健康对照组(P〈0.05);活动期RA患者Th1、Th17及其分泌的细胞因子含量明显高于健康对照组(P〈0.05);非活动期RA患者Th17也明显高于健康对照组(P〈0.05)。结论类风湿关节炎Th1、Th2、Th17平衡改变与其疾病的活动度有关,处于活动期Th1、Th17反应增强,非活动期Th1、Th2、Th17趋于平衡。通过调节Th1、Th2、Th17平衡,有可能为RA的治疗提供一条新思路。 相似文献

Background: Some patients with rheumatoid arthritis and systemic-onset juvenile idiopathic arthritis are resistant to inhibitors of interleukin-1 and tumour necrosis factor. Raised levels of interleukin-6 are associated with both these conditions. Tocilizumab is a humanised monoclonal antibody that binds to both forms of interleukin-6 receptor that has recently been used in Phase III trials in rheumatoid arthritis and systemic-onset juvenile idiopathic arthritis. Methods: The study conducted an evaluation of Phase III trials with tocilizumab. Results: In the Tocilizumab Pivotal Trial in Methotrexate Inadequate Responders the primary efficacy end-point was the proportion of subjects with a 20% improvement in their rheumatoid arthritis signs and symptoms according to the American College of Rheumatology criteria and, at 24 weeks, this value was 26% with placebo and was increased to 48 and 59% with tocilizumab at 4 and 8 mg respectively. In the trial of tocilizumab in systemic-onset juvenile idiopathic arthritis, the primary end-point in the open-label lead-in was the proportion of subjects achieving an American College of Rheumatology Pediatric 30 response and 91% of subjects had achieved this at 6 weeks. This response was maintained by the majority of subjects being treated with tocilizumab during a 12-week double-blind trial and 48 weeks of open trial follow-up. Small numbers of subjects developed infections in both studies. Conclusions: Provided long-term safety can be established, tocilizumab will probably become part of the treatment for rheumatoid arthritis and may become a major breakthrough for the treatment of systemic-onset juvenile idiopathic arthritis. 相似文献

Introduction: Tocilizumab (TCZ), a humanized anti-IL-6 receptor (IL-6R) monoclonal antibody, has demonstrated efficacy and tolerability in several large randomized, controlled trials for the treatment of rheumatoid arthritis (RA). Areas covered: This article compares the safety profile of the newer, subcutaneous (SC) formulation of TCZ with the original intravenous (IV) formulation, in combination with traditional disease-modifying antirheumatic drugs (DMARDs) in patients with RA. Several pivotal clinical trials are included, highlighting data from: i) trials of TCZ-IV; ii) trials of TCZ-SC; and iii) trials comparing IV to SC TCZ. TCZ use in pediatric populations is beyond the scope of this review. Expert opinion: The efficacy and safety of TCZ-IV in the treatment of RA has been demonstrated in multiple clinical trials, both as monotherapy and in combination with traditional DMARDs. The data for TCZ-SC is similar, albeit with a higher frequency of injection site reactions (ISRs). With careful patient selection, the benefit: risk ratio is favorable, offering patients a rapid and sustained reduction in disease activity, improved function and reduced structural damage. Given that most patients prefer SC to IV medication, TCZ-SC will likely become a mainstay, along with other biologic agents, for the treatment of RA patients who have failed traditional non-biologic DMARDs. 相似文献

Tocilizumab is a humanized anti-IL-6 receptor (IL-6R) monoclonal antibody for the treatment of rheumatoid arthritis (RA). A dose of 8 mg/kg produces adequate blockade of IL-6 receptors throughout a dosing interval, as confirmed by sustained high levels of tocilizumab-bound soluble IL6-R complex and normalization of C-reactive protein levels. Studies have confirmed 8 mg/kg every 4 weeks as the optimal dose and 4 mg/kg as the starting dose for the treatment of RA, with favorable efficacy and acceptable safety profiles. After 8 mg/kg, steady-state peak and trough concentrations were 183 ± 86 and 9.7 ± 11 µg/ml, respectively. Tocilizumab serum exposures increased more than proportionally to the dose increase from 2–10 mg/kg. Total clearance is concentration dependent, with non-linear receptor-mediated clearance dominant at low concentrations (<25 µg/ml). Tocilizumab exposures are not affected by common concomitant medications in RA patients, but decreased IL-6 activity resulted in increased CYP3A4 activity and hence decreased exposures of CYP3A4 substrates. 相似文献

目的:检测类风湿关节炎(RA)患者血清中的Dickkopf-1(DKK-1)水平,并探讨其与RA疾病活动的关系。方法:选择2017年10月—2019年12月在山西省汾阳医院风湿免疫科门诊及住院治疗的RA患者44例。详细记录患者治疗前后的临床特点及实验室检测结果。基于28个关节的肿痛情况进行疾病活动性评价(即DAS28评分)。采用酶联免疫吸附法(ELISA)检测治疗前后血清中DKK-1水平。结果:RA患者血清中DKK-1与压痛关节数(TJC)、肿胀关节数(SJC)、DAS28呈正相关(分别为r=0.309,P=0.049;r=0.320,P=0.042;r=0.311,P=0.048),与红细胞沉降率(ESR)、C反应蛋白(CRP)、类风湿因子(RF)、年龄无相关性;治疗前DKK-1在RA患者血清中的表达为(6.62±2.29)μg/L,治疗后为(3.79±1.26)μg/L,两者比较差异有统计学意义(t=7.16,P<0.001)。治疗后TJC,SJC,ESR,CRP,RF,DAS28均较治疗前下降(分别为t=53.14,P<0.001;t=47.78,P<0.001;t=71.83,P=0.022;t=75.59,P=0.049;t=77.60,P=0.032;t=79.29,P<0.001)。结论:DKK-1与RA疾病活动性呈正相关,可视为RA疾病活动的生物标志物。 相似文献

Background: Rheumatoid arthritis (RA) is the most common inflammatory joint disease in adults leading to pain and disability. New drugs, called biologicals, have opened up new possibilities in the treatment of RA. Objective: Targeting pro-inflammatory cytokines such as tumour necrosis factor-α (TNF-α) or interleukin-1 (IL-1) is well established in clinical care of RA patients. However, lack or loss of clinical response occurs in up to 25% of the patients. New strategies beyond these targets, namely blocking T cells by abatacept or B cells by rituximab (RTX), have been introduced recently. Methods: All relevant clinical trials published in peer-reviewed journals are discussed in this article. Data from abstracts presented at congresses have not been included. Conclusion: TNF blocking agents have significantly improved therapy of and outcome in RA patients and, therefore, are still the first choice biologicals for the treatment of RA. Alternatively, abatacept or RTX offer new options in case of inefficacy of or contraindications against anti-TNF therapy. Forthcoming drugs, such as tocilizumab, will extend our armamentarium to treat RA effectively. 相似文献
