Abstract

Background: Trastuzumab-deruxtecan (T-DXd) was approved for the treatment of HER2-positive patients with advanced gastric cancer in Japan based on the results of the DESTINY-Gastric01 trial. This study aimed to collect real-world data and evaluate the effectiveness and safety of T-DXd.

Methods: Patients aged ≥ 20 years at the start of T-DXd administration with a histopathologically confirmed diagnosis of HER2-positive unresectable advanced or recurrent gastric or gastroesophageal junction (GEJ) adenocarcinoma that had worsened after chemotherapy were enrolled in this retrospective cohort study. Key outcomes included T-DXd treatment status, overall survival (OS), real-world progression-free survival (rwPFS), time to treatment failure (TTF), objective response rate and frequency of grade ≥ 3 adverse events (AEs).

Results: Of the 312 patients included in the analysis, 75.3% were male, the median (range) age was 70.0 (27.0-89.0) years, 12.2% had an ECOG PS ≥ 2, 43.3% had ascites and the initial T-DXd dose was > 5.4- ≤ 6.4 mg/kg in 78.2% of patients. The median (95% confidence interval) OS, rwPFS and TTF (months) was 8.9 (8.0-11.0), 4.6 (4.0-5.1) and 3.9 (3.4-4.2), respectively. The response rate was 42.9% in patients with a target lesion. In total, 48.4% of patients experienced a grade ≥ 3 AE, 2.6% experienced grade 5 AEs and 60.9% experienced AEs leading to T-DXd dose adjustments (reduction: 36.9%, interruption: 34.0% or discontinuation: 23.7%). No new safety signals were detected.

Conclusions: T-DXd was effective and had a manageable safety profile as a third- or later-line treatment for patients with HER2-positive gastric or GEJ cancer in Japanese clinical practice.

在日本 HER2 阳性晚期胃癌患者中使用曲妥珠单抗-得舒坦的实际有效性和安全性(EN-DEAVOR 研究)。
背景:根据DESTINY-Gastric01试验的结果,日本批准曲妥珠单抗-德鲁司康(Trastuzumab-deruxtecan,T-DXd)用于治疗HER2阳性的晚期胃癌患者。本研究旨在收集真实世界的数据,评估T-DXd的有效性和安全性:这项回顾性队列研究招募了开始服用 T-DXd 时年龄≥ 20 岁、组织病理学确诊为 HER2 阳性不可切除的晚期或复发性胃癌或胃食管交界处(GEJ)腺癌且化疗后病情恶化的患者。主要结果包括T-DXd治疗状态、总生存期(OS)、实际无进展生存期(rwPFS)、治疗失败时间(TTF)、客观反应率和≥3级不良事件(AEs)频率:在纳入分析的312例患者中,75.3%为男性,中位(范围)年龄为70.0(27.0-89.0)岁,12.2%的患者ECOG PS≥2,43.3%的患者有腹水,78.2%的患者初始T-DXd剂量> 5.4-≤ 6.4 mg/kg。OS、rwPFS和TTF的中位数(95%置信区间)分别为8.9(8.0-11.0)、4.6(4.0-5.1)和3.9(3.4-4.2)个月。靶病灶患者的应答率为42.9%。共有48.4%的患者出现了≥3级AE,2.6%出现了5级AE,60.9%出现了导致T-DXd剂量调整的AE(减量:36.9%,中断:34.0%或停药:23.7%)。未发现新的安全信号:结论:在日本临床实践中,T-DXd作为HER2阳性胃癌或胃食管癌患者的三线或后线治疗药物,疗效显著,安全性可控:临床试验注册:UMIN000049032。
