Purpose: Treatment options for advanced head and neck squamous cell carcinoma (HNSCC) previously treated with platinum-based chemotherapy and a programmed death-1 (PD-1) inhibitor are limited. Trophoblast cell-surface antigen 2 (Trop-2) is highly expressed in HNSCC. Sacituzumab govitecan (SG) is a Trop-2–directed antibody–drug conjugate approved for patients with certain previously treated solid tumors. Methods: TROPiCS-03 (NCT03964727) is an open-label, multicohort, phase 2 study evaluating SG in advanced solid tumors, including HNSCC. Adults with locally advanced or metastatic HNSCC that progressed following platinum-based chemotherapy and anti–PD-(ligand)1 therapy (given sequentially [either order] or in combination) were administered SG 10 mg/kg on days 1 and 8 of a 21-day cycle. The primary endpoint was investigator-assessed objective response rate (ORR). Secondary endpoints included duration of response (DoR), clinical benefit rate (CBR), progression-free survival (PFS), overall survival (OS), and safety. Results: Patients (N=43) received a median of 3 (range, 2–9) prior anticancer regimens. ORR was 16% (95% confidence interval [CI], 7–31%), with 7 confirmed partial responses. CBR was 28% (95% CI, 15–44%). Median (95% CI) DoR, PFS, and OS were 4.2 (2.6–not reached), 4.1 (2.6–5.8), and 9.0 (7.1–10.5) months, respectively. The most common treatment-emergent adverse events (TEAEs) were diarrhea (47%), nausea (47%), and neutropenia (47%). Grade ≥3 TEAEs occurred in 58% of patients. Three patients died owing to TEAEs, with one event (septic shock) considered related to SG. Conclusions: These data demonstrate the clinical potential of Trop-2–directed therapy in managing heavily pretreated patients with advanced HNSCC.

Sacituzumab Govitecan 治疗复发/难治性晚期头颈部鳞状细胞癌患者:2 期 TROPiCS-03 篮子研究的结果
目的:先前接受铂类化疗和程序性死亡 1 (PD-1) 抑制剂治疗的晚期头颈部鳞状细胞癌 (HNSCC) 的治疗选择有限。滋养层细胞表面抗原 2 (Trop-2) 在 HNSCC 中高表达。Sacituzumab govitecan (SG) 是一种 Trop-2 定向抗体-药物偶联物,已获批用于某些既往接受过治疗的实体瘤患者。方法: TROPiCS-03 (NCT03964727) 是一项开放标签、多队列、2 期研究,评估 SG 在晚期实体瘤(包括 HNSCC)中的疗效。对于在铂类化疗和抗 PD-(配体)1 治疗 (序贯 [顺序] 或联合给药) 后进展的局部晚期或转移性 HNSCC 成人患者,在 21 天周期的第 1 天和第 8 天给予 SG 10 mg/kg。主要终点是研究者评估的客观缓解率 (ORR)。次要终点包括缓解持续时间 (DoR) 、临床获益率 (CBR) 、无进展生存期 (PFS) 、总生存期 (OS) 和安全性。结果:患者 (N=43) 既往接受抗癌方案的中位数为 3 (范围,2-9)。ORR 为 16% (95% 置信区间 [CI],7-31%),其中 7 例确认了部分反应。CBR 为 28% (95% CI, 15–44%)。中位 (95% CI) DoR、PFS 和 OS 分别为 4.2 (2.6-未达到)、4.1 (2.6-5.8) 和 9.0 (7.1-10.5) 个月。最常见的治疗中出现的不良事件 (TEAE) 是腹泻 (47%) 、恶心 (47%) 和中性粒细胞减少症 (47%)。58% 的患者发生 ≥3 级 TEAE。3 例患者死于 TEAEs,其中 1 例事件 (感染性休克) 被认为与 SG 有关。结论: 这些数据证明了 Trop-2 定向疗法在管理既往接受过大量治疗的晚期 HNSCC 患者中的临床潜力。
