ObjectiveTo describe recent trends in DMARD use for children with juvenile idiopathic arthritis (JIA) in the US.MethodsWe used commercial claims data (2000‐2022) to perform a serial cross‐sectional utilization study of children ages 1‐18 diagnosed with JIA. Initiations of conventional synthetic (cs), biologic (b), or targeted synthetic (ts) DMARDs were identified after a ≥12‐month baseline and expressed as percentage of all new DMARD initiations per year, by category, class, and individual agent. Trends were evaluated using linear regression. Secondarily, we examined first b/tsDMARDs initiated after csDMARD monotherapy.ResultsWe identified 20,258 new DMARD use episodes among 13,696 individuals (median age 14 years, 67.5% female). csDMARDs, while most commonly used overall, declined from 89.5% of new use episodes to 43.2% (2001‐2022, p<0.001 for trend). In contrast, bDMARD use increased (10.5‐50.0%, p<0.001). For tumor necrosis factor inhibitors (TNFi), etanercept peaked at 28.3% (2006) and declined to 4.2% (2022) (p=0.002). Meanwhile, adalimumab use doubled (7.0‐14.0%, 2007‐2008) after JIA approval, increasing further following a less painful formulation release (20.5%, 2022, p<0.001). However, overall TNFi use has declined with increasing use of other b/tsDMARDs, particularly ustekinumab, secukinumab, and tofacitinib. By 2022, adalimumab was the most common b/tsDMARD initiated first after csDMARDs (77.8%).ConclusionAmong commercially insured children with JIA in the US, new b/tsDMARD use is rising while new csDMARD use declines. For b/tsDMARDs, adalimumab is most used and the predominant b/tsDMARD initiated first after csDMARDs. Patterns in DMARD use for JIA have evolved relative to multiple factors, including regulatory approvals and tolerability.

2001-2022 年美国商业保险儿童幼年特发性关节炎中改善病情的抗风湿药的新应用趋势



目的描述美国幼年特发性关节炎 (JIA) 患儿 DMARD 使用的最新趋势。方法我们使用商业索赔数据 (2000-2022) 对 1-18 岁被诊断患有 JIA 的儿童进行了系列横断面利用研究。在 ≥12 个月基线后确定常规合成 (cs) 、生物 (b) 或靶向合成 (ts) DMARD 的启动,并表示为每年所有新 DMARD 启动的百分比,按类别、类别和单个药物。使用线性回归评估趋势。其次,我们首先检查了 csDMARD 单药治疗后开始的 b/tsDMARDs。结果我们在 13,696 人中确定了 20,258 例新的 DMARD 使用事件 (中位年龄 14 岁,67.5% 为女性)。csDMARD 虽然总体上最常用,但从新使用次数的 89.5% 下降到 43.2%(2001-2022 年,趋势 p<0.001)。相比之下,bDMARD 的使用增加 (10.5-50.0%,p<0.001)。对于肿瘤坏死因子抑制剂 (TNFi),依那西普达到 28.3% 的峰值(2006 年),并下降至 4.2%(2022 年)(p = 0.002)。同时,在 JIA 批准后,阿达木单抗的使用量翻了一番(7.0-14.0%,2007-2008 年),在减轻痛苦的制剂发布后进一步增加(20.5%,2022 年,p<0.001)。然而,随着其他 b/tsDMARD 使用的增加,尤其是乌司奴单抗、苏金单抗和托法替布,TNFi 的总体使用量有所下降。到 2022 年,阿达木单抗是最常见的 b/tsDMARD 药物,仅次于 csDMARD (77.8%)。结论在美国商业保险的 JIA 患儿中,新发 b/tsDMARD 使用量上升,而新发 csDMARD 使用量下降。对于 b/tsDMARDs,阿达木单抗使用最常用,并且主要的 b/tsDMARD 在 csDMARD 之后首先开始使用。DMARD 治疗 JIA 的模式相对于多种因素发生了变化,包括监管批准和耐受性。
