Niraparib, an inhibitor of poly(adenosine diphosphate [ADP]-ribose) polymerase (PARP), has been associated with significantly increased progression-free survival among patients with recurrent ovarian cancer after platinum-based chemotherapy, regardless of the presence or absence of mutations. The efficacy of niraparib in patients with newly diagnosed advanced ovarian cancer after a response to first-line platinum-based chemotherapy is unknown.
In this randomized, double-blind, phase 3 trial, we randomly assigned patients with newly diagnosed advanced ovarian cancer in a 2:1 ratio to receive niraparib or placebo once daily after a response to platinum-based chemotherapy. The primary end point was progression-free survival in patients who had tumors with homologous-recombination deficiency and in those in the overall population, as determined on hierarchical testing. A prespecified interim analysis for overall survival was conducted at the time of the primary analysis of progression-free survival.
Of the 733 patients who underwent randomization, 373 (50.9%) had tumors with homologous-recombination deficiency. Among the patients in this category, the median progression-free survival was significantly longer in the niraparib group than in the placebo group (21.9 months vs. 10.4 months; hazard ratio for disease progression or death, 0.43; 95% confidence interval [CI], 0.31 to 0.59; P<0.001). In the overall population, the corresponding progression-free survival was 13.8 months and 8.2 months (hazard ratio, 0.62; 95% CI, 0.50 to 0.76; P<0.001). At the 24-month interim analysis, the rate of overall survival was 84% in the niraparib group and 77% in the placebo group (hazard ratio, 0.70; 95% CI, 0.44 to 1.11). The most common adverse events of grade 3 or higher were anemia (in 31.0% of the patients), thrombocytopenia (in 28.7%), and neutropenia (in 12.8%). No treatment-related deaths occurred.
Among patients with newly diagnosed advanced ovarian cancer who had a response to platinum-based chemotherapy, those who received niraparib had significantly longer progression-free survival than those who received placebo, regardless of the presence or absence of homologous-recombination deficiency.

尼拉帕利是一种聚(二腺苷二磷酸核糖)聚合酶(PARP)抑制剂,与铂类化疗后复发性卵巢癌患者的无进展生存期显著增加相关,无论是否存在突变。在一线铂类化疗后有反应的新诊断晚期卵巢癌患者中,尼拉帕利的疗效尚不清楚。
在这项随机、双盲、3 期临床试验中,我们以 2:1 的比例随机分配新诊断的晚期卵巢癌患者,在铂类化疗后有反应的情况下,每天接受尼拉帕利或安慰剂治疗。主要终点是同源重组缺陷患者和总体人群的无进展生存期,这是在分层检验中确定的。在无进展生存的主要分析时,进行了总体生存的预先指定的中期分析。
在 733 名接受随机分组的患者中,有 373 名(50.9%)肿瘤存在同源重组缺陷。在这一类别中,尼拉帕利组的中位无进展生存期明显长于安慰剂组(21.9 个月 vs. 10.4 个月;疾病进展或死亡的风险比为 0.43;95%置信区间 [CI],0.31 至 0.59;P<0.001)。在总体人群中,相应的无进展生存期为 13.8 个月和 8.2 个月(风险比为 0.62;95%CI,0.50 至 0.76;P<0.001)。在 24 个月的中期分析中,尼拉帕利组的总生存率为 84%,安慰剂组为 77%(风险比为 0.70;95%CI,0.44 至 1.11)。最常见的 3 级或以上不良事件为贫血(31.0%的患者)、血小板减少(28.7%)和中性粒细胞减少(12.8%)。没有与治疗相关的死亡事件发生。
在铂类化疗后有反应的新诊断晚期卵巢癌患者中,与安慰剂相比,接受尼拉帕利治疗的患者无进展生存期显著延长,无论是否存在同源重组缺陷。(由葛兰素史克公司资助;PRIMA/ENGOT-OV26/GOG-3012 临床试验.gov 编号,NCT02655016。)
