摘要

简介在JAVELIN Bladder 100研究中，阿维列单抗一线维持治疗（1LM）与最佳支持治疗相比，提高了局部晚期/转移性尿路上皮癌（la/mUC）患者的总生存期（OS）和无进展生存期（PFS）。PATRIOT-II描述了阿维列单抗1LM的实际疗效：这项在美国社区/学术中心进行的阿维列单抗1LM观察性、回顾性研究使用了从阿维列单抗开始治疗≥12个月时收集的病历数据，以评估生存率、安全性和医疗资源利用率；分析为描述性分析：研究纳入了来自 37 个中心的 160 名患者（中位年龄 70 岁；77% 为男性）。阿维列单抗 1LM 在 PBC 结束后中位 4 周（IQR 3-6）时启动。阿维列单抗1LM的中位随访时间为16个月（IQR为11-21）。研究结束时，19.4%的患者继续使用阿维单抗；73.7%的患者因病情进展、不良事件（AE）或表现状态恶化而停药。从开始使用阿维鲁单抗起，中位PFS和OS分别为5.4个月（95% CI，3.8-6.9）和24.4个月（95% CI，20.4-28.4）。15名患者（9.4%）出现了≥3级治疗相关AEs（TRAEs）；35名患者（21.9%）出现了任何级别的免疫相关AEs，23名患者（14.3%）因AEs接受了大剂量全身皮质类固醇治疗。44名患者（27.5%）在阿维鲁单抗治疗期间住院，其中13名患者（8.1%）因TRAE住院。本研究的局限性包括样本量较小、潜在的选择偏倚以及数据缺失/未知：这些结果与JAVELIN Bladder 100临床试验及其他实际研究结果一致，支持阿维列单抗1LM用于1L PBC后无进展的la/mUC患者。

Avelumab First-Line Maintenance for Locally Advanced or Metastatic Urothelial Carcinoma: Results From the Real-World US PATRIOT-II Study

Introduction

In JAVELIN Bladder 100, avelumab first-line maintenance (1LM) improved overall survival (OS) and progression-free survival (PFS) in patients with locally advanced/metastatic urothelial carcinoma (la/mUC) without progression following 1L platinum-based chemotherapy (PBC) versus best supportive care. PATRIOT-II describes real-world outcomes with avelumab 1LM.

Patients and Methods

This observational, retrospective study of avelumab 1LM in US community/academic centers used medical record data collected from avelumab initiation for ≥12 months to assess survival, safety, and healthcare resource utilization; analyses are descriptive.

Results

The study included 160 patients from 37 centers (median age, 70 years; 77% male). Avelumab 1LM was initiated at a median of 4 weeks (IQR 3-6) after PBC completion. Median follow-up from avelumab 1LM was 16 months (IQR 11-21). At study end, 19.4% of patients continued avelumab; 73.7% had discontinued due to progression, adverse events (AEs), or performance status deterioration. Median PFS and OS from avelumab initiation were 5.4 months (95% CI, 3.8-6.9) and 24.4 months (95% CI, 20.4-28.4), respectively. Grade ≥3 treatment-related AEs (TRAEs) occurred in 15 patients (9.4%); 35 (21.9%) had any-grade immune-related AEs, and 23 (14.3%) received high-dose systemic corticosteroids for AEs. Forty-four patients (27.5%) were hospitalized during the avelumab treatment period, of whom 13 (8.1%) were hospitalized due to TRAEs. Limitations of this study include a small sample size, potential selection bias, and missing/unknown data.

Conclusion

These results align with the JAVELIN Bladder 100 clinical trial and other real-world studies, supporting avelumab 1LM use in patients with la/mUC without progression following 1L PBC.
