INTRODUCTION The Seneca Valley Virus (NTX-010) is an oncolytic picornavirus with tropism for small cell lung cancer (SCLC). This phase II double-blind, placebo controlled trial evaluated NTX-010 in patients with extensive stage (ES) SCLC after completion of first line chemotherapy. METHODS ES-SCLC patients who did not progress after ≥4 cycles of platinum-based chemotherapy were randomized 1:1 to a single dose of NTX-010 or placebo within 12 weeks of chemotherapy. Primary end point was progression free survival (PFS). A prespecified interim analysis for futility was performed after 40 events. Viral clearance and the development of neutralizing antibodies were followed. RESULTS From January 15, 2010 to January 10, 2013, 50 patients were randomized and received therapy on study (26 NTX-010, 24 placebo). At the specified interim analysis, median PFS was 1.7 months (95% confidence interval (CI) 1.4-3.1 months) for the NTX-010 group versus 1.7 months (95% CI 1.4-4.3 months) for placebo (hazard ratio (HR): 1.03, p = 0.92), and the trial was terminated due to futility. In the NTX-010 group, PFS was shorter in patients with detectable virus at days 7 and 14 versus not detected after treatment (1.0 month (95% CI 0.4-1.5 months) vs 1.8 months (95% CI 1.3-5.5 months; p=0.008); and 0.9 months (95% CI 0.4-2.6 months) vs 1.3 months (95% CI 1.0-5.3 months), p=0.04) respectively. CONCLUSIONS Patients with ES-SCLC did not benefit from NTX-010 treatment after chemotherapy with a platinum doublet. Persistence of NTX-010 in the blood 1 or 2 weeks after treatment was associated with a shorter PFS.

一项关于 Seneca Valley Virus (NTX-010) 与安慰剂的随机双盲 II 期研究,用于治疗至少 4 个周期的铂类化疗后稳定或有反应的广泛期 SCLC (ES-SCLC) 患者:NCCTG (Alliance ) N0923 研究

简介 Seneca Valley 病毒 (NTX-010) 是一种溶瘤性微小核糖核酸病毒,对小细胞肺癌 (SCLC) 具有嗜性。这项 II 期双盲、安慰剂对照试验评估了 NTX-010 在完成一线化疗后的广泛期 (ES) SCLC 患者中的作用。方法 ≥ 4 个周期的铂类化疗后未进展的 ES-SCLC 患者在化疗 12 周内按 1:1 随机分配至单剂量 NTX-010 或安慰剂组。主要终点是无进展生存期(PFS)。在 40 次事件后进行了预先指定的无效期中期分析。跟踪病毒清除和中和抗体的产生。结果 从 2010 年 1 月 15 日到 2013 年 1 月 10 日,50 名患者被随机分组​​并接受治疗(26 NTX-010,24 安慰剂)。在指定的中期分析中,NTX-010 组的中位 PFS 为 1.7 个月(95% CI 1.4-3.1 个月),而安慰剂组为 1.7 个月(95% CI 1.4-4.3 个月)(风险比(HR):1.03,p = 0.92 ),审判因无效而终止。在 NTX-010 组中,与治疗后未检测到病毒相比,在第 7 天和第 14 天检测到病毒的患者的 PFS 更短(1.0 个月(95% CI 0.4-1.5 个月)与 1.8 个月(95% CI 1.3-5.5 个月;p) =0.008);和 0.9 个月(95% CI 0.4-2.6 个月)与 1.3 个月(95% CI 1.0-5.3 个月),p=0.04)。结论 ES-SCLC 患者在铂类双药化疗后未从 NTX-010 治疗中获益。治疗后 1 或 2 周血液中 NTX-010 的持续存在与较短的 PFS 相关。安慰剂组 7 个月(95% CI 1.4-4.3 个月)(风险比 (HR):1.03,p = 0.92),试验因无效而终止。在 NTX-010 组中,与治疗后未检测到病毒相比,在第 7 天和第 14 天检测到病毒的患者的 PFS 更短(1.0 个月(95% CI 0.4-1.5 个月)与 1.8 个月(95% CI 1.3-5.5 个月;p) =0.008);和 0.9 个月(95% CI 0.4-2.6 个月)与 1.3 个月(95% CI 1.0-5.3 个月),p=0.04)。结论 ES-SCLC 患者在铂类双药化疗后未从 NTX-010 治疗中获益。治疗后 1 或 2 周血液中 NTX-010 的持续存在与较短的 PFS 相关。安慰剂组 7 个月(95% CI 1.4-4.3 个月)(风险比 (HR):1.03,p = 0.92),试验因无效而终止。在 NTX-010 组中,与治疗后未检测到病毒相比,在第 7 天和第 14 天检测到病毒的患者的 PFS 更短(1.0 个月(95% CI 0.4-1.5 个月)与 1.8 个月(95% CI 1.3-5.5 个月;p) =0.008);和 0.9 个月(95% CI 0.4-2.6 个月)与 1.3 个月(95% CI 1.0-5.3 个月),p=0.04)。结论 ES-SCLC 患者在铂类双药化疗后未从 NTX-010 治疗中获益。治疗后 1 或 2 周血液中 NTX-010 的持续存在与较短的 PFS 相关。与治疗后未检测到病毒相比,第 7 天和第 14 天检测到病毒的患者的 PFS 更短(1.0 个月(95% CI 0.4-1.5 个月)与 1.8 个月(95% CI 1.3-5.5 个月;p=0.008)和 0.9 个月(95% CI 0.4-2.6 个月)与 1.3 个月(95% CI 1.0-5.3 个月),p=0.04)。结论 ES-SCLC 患者在铂类双药化疗后未从 NTX-010 治疗中获益。治疗后 1 或 2 周血液中 NTX-010 的持续存在与较短的 PFS 相关。与治疗后未检测到病毒相比,第 7 天和第 14 天检测到病毒的患者的 PFS 更短(1.0 个月(95% CI 0.4-1.5 个月)与 1.8 个月(95% CI 1.3-5.5 个月;p=0.008)和 0.9 个月(95% CI 0.4-2.6 个月)与 1.3 个月(95% CI 1.0-5.3 个月),p=0.04)。结论 ES-SCLC 患者在铂类双药化疗后未从 NTX-010 治疗中获益。治疗后 1 或 2 周血液中 NTX-010 的持续存在与较短的 PFS 相关。
