Abstract

Background

The purpose of this study was to report an updated, final analysis with longer follow-up for the open-label phase III RATIONALE-304 study of first-line tislelizumab plus chemotherapy versus chemotherapy alone for advanced nonsquamous non-small-cell lung cancer (nsq-NSCLC).

Materials and methods

Patients with histologically confirmed stage IIIB/IV nsq-NSCLC were randomized (2 : 1) to 4-6 cycles of tislelizumab plus platinum-based chemotherapy and pemetrexed every 3 weeks, followed by maintenance tislelizumab and pemetrexed, or platinum-based chemotherapy and pemetrexed alone every 3 weeks followed by maintenance pemetrexed. The primary endpoint was independent review committee (IRC)-assessed progression-free survival (PFS_IRC). Overall survival (OS), safety, and tolerability were secondary endpoints.

Results

Overall, 334 patients were randomized (tislelizumab plus chemotherapy: n = 223; chemotherapy: n = 111). At final analysis (median follow-up 16.1 months), safety/tolerability profiles in both arms were consistent with the interim analysis. Tislelizumab plus chemotherapy continued to demonstrate prolongation of PFS_IRC versus chemotherapy alone {stratified hazard ratio (HR) 0.63 [95% confidence interval (CI) 0.47-0.86]; median PFS_IRC 9.8 months (95% CI 8.9-11.7 months) versus 7.6 months (95% CI 5.6-8.0 months), respectively}. OS stratified HR for tislelizumab plus chemotherapy versus chemotherapy was 0.90 (95% CI 0.63-1.28), with median OS of 21.4 months (95% CI 17.7 months-not estimable) versus 21.3 months (95% CI 15.6 months-not estimable), respectively. At a subsequent ad hoc analysis (median follow-up 19.3 months), OS HR between arms was 0.85 (95% CI 0.63-1.14); when adjusted for crossover using the two-stage method, the OS HR was 0.68 (95% CI 0.48-0.96).

Conclusions

After longer follow-up, first-line tislelizumab plus chemotherapy continued to demonstrate a manageable safety profile and a favorable PFS benefit over chemotherapy alone in patients with advanced/metastatic nsq-NSCLC.

Tislelizumab 联合化疗作为局部晚期或转移性非鳞状非小细胞肺癌的一线治疗（RATIONALE-304：随机 III 期试验的最终分析）。

研究背景本研究的目的是报告开放标签III期RATIONALE-304研究的最新最终分析结果和更长的随访时间，该研究的目的是对晚期非鳞状非小细胞肺癌（nsq-NSCLC）一线替舒瑞单抗联合化疗与单独化疗进行对比：组织学确诊的IIIB/IV期nsq-NSCLC患者被随机分配（2:1）至4-6个周期的替舒利珠单抗+铂类化疗和培美曲塞，每3周1次，然后维持替舒利珠单抗和培美曲塞；或铂类化疗和培美曲塞，每3周1次，然后维持培美曲塞。主要终点是独立审查委员会（IRC）评估的无进展生存期（PFSIRC）。总生存期（OS）、安全性和耐受性是次要终点：共有 334 名患者接受了随机治疗（替莱珠单抗加化疗：223 人；化疗：111 人）。在最终分析中（中位随访16.1个月），两组患者的安全性/耐受性情况与中期分析结果一致。Tislelizumab联合化疗与单独化疗相比，PFSIRC继续延长{分层危险比（HR）0.63[95%置信区间（CI）0.47-0.86]；中位PFSIRC分别为9.8个月（95% CI 8.9-11.7个月）与7.6个月（95% CI 5.6-8.0个月）}。tislelizumab联合化疗与化疗的OS分层HR为0.90（95% CI 0.63-1.28），中位OS分别为21.4个月（95% CI 17.7个月，无法估计）与21.3个月（95% CI 15.6个月，无法估计）。在随后的临时分析中（中位随访19.3个月），两组间的OS HR为0.85（95% CI 0.63-1.14）；如果使用两阶段法对交叉进行调整，OS HR为0.68（95% CI 0.48-0.96）：结论：经过更长时间的随访，一线替赛珠单抗联合化疗在晚期/转移性nsq-NSCLC患者中继续显示出可控的安全性，并且与单用化疗相比，PFS获益更多。
