Phase 3, open label, multicentre, randomised trial.
Four hospitals located in China between September 2019 and August 2022.
Adults (≥18 years) with recurrent or metastatic nasopharyngeal carcinoma.
Patients were randomised in a 1:1 ratio to treatment with either nab-paclitaxel (200 g/m2 on day 1), cisplatin (60 mg/m2 on day 1), and capecitabine (1000 mg/m2 twice on days 1-14) or gemcitabine (1 g/m2 on days 1 and 8) and cisplatin (80 mg/m2 on day 1).
Progression-free survival was evaluated by the independent review committee as the primary endpoint in the intention-to-treat population.
The median follow-up was 15.8 months in the prespecified interim analysis (31 October 2022). As assessed by the independent review committee, the median progression-free survival was 11.3 (95% confidence interval 9.7 to 12.9) months in the nab-TPC cohort compared with 7.7 (6.5 to 9.0) months in the gemcitabine and cisplatin cohort. The hazard ratio was 0.43 (95% confidence interval 0.25 to 0.73; P=0.002). The objective response rate in the nab-TPC cohort was 83% (34/41) versus 63% (25/40) in the gemcitabine and cisplatin cohort (P=0.05), and the duration of response was 10.8 months in the nab-TPC cohort compared with 6.9 months in the gemcitabine and cisplatin cohort (P=0.009). Treatment related grade 3 or 4 adverse events, including leukopenia (4/41 (10%) v 13/40 (33%); P=0.02), neutropenia (6/41 (15%) v 16/40 (40%); P=0.01), and anaemia (1/41 (2%) v 8/40 (20%); P=0.01), were higher in the gemcitabine and cisplatin cohort than in the nab-TPC cohort. No deaths related to treatment occurred in either treatment group. Survival and long term toxicity are still being evaluated with longer follow-up.
The nab-TPC regimen showed a superior antitumoural efficacy and favourable safety profile compared with gemcitabine and cisplatin for recurrent or metastatic nasopharyngeal carcinoma. Nab-TPC should be considered the standard first line treatment for recurrent or metastatic nasopharyngeal carcinoma. Longer follow-up is needed to confirm the benefits for overall survival.

方法:阶段3,开放标签,多中心,随机试验。
方法:2019年9月至2022年8月,中国有四家医院。
方法:患有复发性或转移性鼻咽癌的成人(≥18岁)。
方法:患者以1:1的比例随机分配给nab-紫杉醇(第1天200g/m2),顺铂(第1天60mg/m2),和卡培他滨(第1-14天两次1000mg/m2)或吉西他滨(第1天和第8天1g/m2)和顺铂(第1天80mg/m2)。
方法:由独立审查委员会评估无进展生存期作为意向治疗人群的主要终点。
结果:在预设的中期分析中,中位随访时间为15.8个月(2022年10月31日)。根据独立审查委员会的评估,nab-TPC队列的中位无进展生存期为11.3个月(95%置信区间9.7~12.9个月),而吉西他滨和顺铂队列的中位无进展生存期为7.7个月(6.5~9.0个月).风险比为0.43(95%置信区间为0.25至0.73;P=0.002)。nab-TPC组的客观缓解率为83%(34/41),而吉西他滨和顺铂组的客观缓解率为63%(25/40)(P=0.05),nab-TPC队列的缓解持续时间为10.8个月,而吉西他滨和顺铂队列的缓解持续时间为6.9个月(P=0.009).治疗相关的3级或4级不良事件,包括白细胞减少症(4/41(10%)v13/40(33%);P=0.02),中性粒细胞减少症(6/41(15%)v16/40(40%);P=0.01),贫血(1/41(2%)v8/40(20%);P=0.01),吉西他滨和顺铂队列高于nab-TPC队列。在任一治疗组中均未发生与治疗相关的死亡。生存和长期毒性仍在进行长期随访评估。
结论:与吉西他滨和顺铂相比,nab-TPC方案对复发或转移性鼻咽癌具有更高的抗肿瘤疗效和良好的安全性。Nab-TPC应被视为复发性或转移性鼻咽癌的标准一线治疗方法。需要更长时间的随访以确认总体生存的益处。
