Background: Treatments after anti-PD-1 therapy for patients with recurrent, metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) are limited. Blocking phosphatidylinositol 3-kinase (PI3K) signaling may lead to tumor immunomodulation and enhanced taxane sensitivity. This phase 2 trial evaluated dual, selective PI3Kδ/γ inhibition with docetaxel in patients with anti-PD-1 refractory R/M HNSCC. Design: Patients received duvelisib (25 mg orally twice daily) with docetaxel (75 mg/m2 IV) every 21-days. The primary endpoint was overall response rate (ORR) (RECISTv1.1), employing a Simon two-stage design. Secondary endpoints: safety, progression-free survival (PFS), overall survival (OS); exploratory endpoints: correlating immunologic and genomic parameters with outcomes. Results: From 11/1/21 to 10/10/23, 26 patients enrolled (median age: 64, 96% men, 54% with HPV+ disease; primary site: 12 oropharynx, 11 oral cavity, 3 larynx/hypopharynx. Best ORR was 19% (5/26) (95%CI: 6.8-40.7%), all were partial responses (median duration: 5.1 months [0.7-15.5]); 46% (12/26) exhibited stable disease and 32% (8/26) progression (1 unevaluable). Two patients remain on-treatment at data cutoff; 25% (6/24) came off for toxicity. Grade 3+ treatment-related adverse events were observed in 50% (13/26), most often elevated liver function tests (6, 23%). No deaths were treatment related. At median follow-up of 6.5 months (0.7-26), median PFS: 2.8 months (95%CI: 1.9-7.0); 17/26 patients had died. Median OS: 10.2 months (95%CI: 6.7-15.9), favoring HPV-negative patients. Greater tumor CD3+/CD8+ T cell infiltration trended with improved outcomes. Conclusion(s): We report a favorable response rate when combining a selective PI3K pathway inhibitor and taxane in patients with anti-PD-1 refractory HNSCC. ClinicalTrials.gov: NCT05057247

Duvelisib 联合多西他赛治疗抗 PD-1 难治性、复发性或转移性头颈部鳞状细胞癌患者
背景: 复发性、转移性 (R/M) 头颈部鳞状细胞癌 (HNSCC) 患者抗 PD-1 治疗后的治疗是有限的。阻断磷脂酰肌醇 3-激酶 (PI3K) 信号传导可能导致肿瘤免疫调节和紫杉烷敏感性增强。该 2 期试验评估了多西他赛对抗 PD-1 难治性 R/M HNSCC 患者的双重选择性 PI3Kδ/γ 抑制。设计: 患者每 21 天接受 duvelisib (25 mg 口服,每天两次) 和多西他赛 (75 mg/m2 IV)。主要终点是总缓解率 (ORR) (RECISTv1.1),采用 Simon 两阶段设计。次要终点:安全性、无进展生存期 (PFS)、总生存期 (OS);探索性终点:将免疫学和基因组参数与结果相关联。结果:从 21 年 11 月 1 日至 23 年 10 月 10 日,入组了 26 名患者(中位年龄:64 岁,96% 男性,54% 患有 HPV+ 疾病;主要部位:12 个口咽,11 个口腔,3 个喉/下咽。最佳 ORR 为 19% (5/26) (95% CI: 6.8-40.7%),均为部分缓解 (中位持续时间: 5.1 个月 [0.7-15.5]);46% (12/26) 表现出疾病稳定,32% (8/26) 进展 (1 例无法评估)。两名患者在数据截止时仍在接受治疗;25% (6/24) 因毒性而脱落。在 50% (13/26) 中观察到 3+ 级治疗相关不良事件,最常见的是肝功能检查升高 (6, 23%)。没有死亡与治疗相关。中位随访 6.5 个月 (0.7-26),中位 PFS:2.8 个月 (95% CI:1.9-7.0);17/26 名患者死亡。中位 OS:10.2 个月 (95% CI: 6.7-15.9),有利于 HPV 阴性患者。更大的肿瘤 CD3 + / CD8 + T 细胞浸润呈改善趋势,结果改善。 结论: 我们报告了在抗 PD-1 难治性 HNSCC 患者中联合选择性 PI3K 通路抑制剂和紫杉烷时具有良好的反应率。临床试验。政府: NCT05057247
