Abstract

Background

ReFLECT was a French, prospective, multicenter, observational cohort study evaluating the effectiveness and safety of the infliximab (IFX) biosimilar CT-P13 in a real-world setting. Here, we describe the results for adults with inflammatory bowel disease (IBD).

Methods

Eligible patients with IBD were recruited and received intravenous CT-P13 induction and/or maintenance therapy; patients were either naive to IFX (IFX-naive) or previously treated with IFX originator or another IFX biosimilar (IFX-switched). The primary objective was CT-P13 persistence, which was measured as a time-dependent variable during a two-year follow-up period with four prespecified visits. Safety was assessed.

Results

The adult IBD population comprised 530 patients with Crohn's disease (CD), including 327 categorized as IFX-naive, 188 as IFX-switched, 11 as other (i.e., previously received IFX but received another treatment before switching to CT-P13), and 4 with missing data; and 221 patients with ulcerative colitis (UC), including 152 categorized as IFX-naive, 59 as IFX-switched, 8 as other, and 2 with missing data. After two years of follow-up, the rates of CT-P13 persistence were 71.7 % (95 % CI: 66.7, 77.0) and 63.7 % (55.3, 73.3) in patients with CD and UC, respectively. CT-P13 persistence was greater for IFX-switched patients than for IFX-naive patients (CD: 83.7 % [95 % CI: 78.0, 89.9] vs 65.7 % [58.6, 73.7]; UC: 91.2 % [81.7, 100.0] vs 53.4 % [43.0, 66.2]). The main reason for CT-P13 discontinuation was loss of response (CD/UC) in both IFX-naive (14.7 %/21.7 %) and IFX-switched (7.4 %/5.1 %) groups. Among patients (CD and UC, respectively), 51.3 % and 45.2 % reported ≥1 adverse event (AE), and 13.2 % and 12.7 % reported serious AEs, respectively.

Conclusion

After two years of follow-up, the effectiveness of intravenous CT-P13 was maintained in >80 % of IFX-switched patients. CT-P13 induced effective therapeutic maintenance in IFX-naive patients. CT-P13 had an acceptable safety profile.

英夫利昔单抗生物类似物 CT-P13 治疗炎症性肠病的实际有效性和安全性：一项前瞻性全国观察队列研究（ReFLECT 研究）。

研究背景ReFLECT 是一项法国前瞻性多中心观察性队列研究，评估了英夫利昔单抗 (IFX) 生物仿制药 CT-P13 在真实世界中的有效性和安全性。在此，我们将介绍针对成人炎症性肠病（IBD）患者的研究结果：我们招募了符合条件的 IBD 患者，他们接受了 CT-P13 的静脉诱导和/或维持治疗；患者要么对 IFX 不敏感（IFX-naive），要么曾接受过 IFX 原研药或另一种 IFX 生物仿制药的治疗（IFX-switched）。主要目标是CT-P13的持续性，在为期两年的随访期间，以时间变量的形式测量CT-P13的持续性。此外还评估了安全性：成年 IBD 患者包括 530 名克罗恩病 (CD) 患者，其中 327 名为 IFX-naive，188 名为 IFX-switched，11 名为其他（即之前接受过 IFX 但在转用 CT-P13 之前接受过其他治疗），4 名数据缺失；溃疡性结肠炎 (UC) 患者 221 名，其中 152 名为 IFX-naive，59 名为 IFX-switched，8 名为其他，2 名数据缺失。随访两年后，CD 和 UC 患者的 CT-P13 持续率分别为 71.7% (95% CI: 66.7, 77.0) 和 63.7% (55.3, 73.3)。IFX转换患者的CT-P13持续率高于IFX免疫患者（CD：83.7% [95% CI：78.0, 89.9] vs 65.7% [58.6, 73.7]；UC：91.2% [81.7, 89.9] vs 65.7% [58.6, 73.7]）：91.2%[81.7，100.0] vs 53.4% [43.0，66.2]）。IFX-naive组（14.7%/21.7%）和IFX-switched组（7.4%/5.1%）停用CT-P13的主要原因是反应消失（CD/UC）。在患者（CD组和UC组）中，分别有51.3%和45.2%的患者报告了≥1次不良事件（AE），分别有13.2%和12.7%的患者报告了严重不良事件：经过两年的随访，超过80%的IFX转换患者维持了静脉注射CT-P13的疗效。CT-P13能有效维持IFX-naive患者的疗效。CT-P13的安全性可接受：试验注册：ClinicalTrials.gov identifier：NCT02925338。
