       2017年11月30日,百時美施貴寶便公布了獨立數(shù)據(jù)監(jiān)測委員會關(guān)于CheckMate-078的分析結(jié)果,臨床試驗達到總生存期主要終點,提前完成試驗。

       CheckMate-078是一項主要在中國人群開展的臨床3期、隨機、多中心的臨床試驗,評估Nivolumab對比多西他賽治療既往接受過治療的晚期或轉(zhuǎn)移性非小細胞安全性和有效性。對應(yīng)的臨床受理號為JXSL1300032。

       CheckMate-078表明,相比多西他賽,Opdivo能夠使中國經(jīng)治非小細胞肺癌患者總生存期顯著獲益(HR 0.68,p=0.0006),并能夠降低疾病進展風(fēng)險,獲得具有統(tǒng)計學(xué)意義的臨床收益,這與CheckMate-017和CheckMate-057總生存期數(shù)據(jù)保持一致。

       Abstract

       Introduction: Lung cancer incidence in China has increased and it remains the leading cause of cancer death, highlighting a need for new treatments. We report results from CheckMate 078, the first phase 3 study of an anti-programmed death (ligand) 1 (PD-[L]1) agent in predominantly Chinese patients with NSCLC and disease progression after platinum (Pt)-based chemotherapy.

       Methods: Patients who had disease progression during or after Pt-based doublet chemotherapy were randomized 2:1 to receive nivolumab (3 mg/kg Q2W) or docetaxel (75 mg/m2 Q3W). Patients were included regardless of tumor histology or PD-L1 expression, and randomization was stratified according to both of these factors (≥1% vs <1%/unevaluable tumor PD-L1; squamous vs non-squamous histology). Patients with epidermal growth factor receptor mutation-positive tumors were excluded. The primary endpoint was overall survival (OS); other endpoints included progression-free survival (PFS) and objective response rate (ORR).

       Results: 639 patients were enrolled from December 2015 to December 2016; 504 were randomized. Of all randomized patients, ~90% were from China, 60% had non-squamous tumor histology; tumor PD-L1 expression was <1% in 41% of patients and ≥1% in 50% of patients (9% unevaluable). Minimum follow-up was 8.8 months. OS was significantly improved with nivolumab (n=338) vs docetaxel (n=166); median OS was 12.0 vs 9.6 months, respectively (hazard ratio [HR; 97.7% CI]: 0.68 [0.52, 0.90]; P<0.001). The HR (95% CI) for OS was 0.61 (0.42, 0.89) in patients with squamous NSCLC and 0.76 (0.56, 1.04) in patients with non-squamous NSCLC. In patients with tumor PD-L1 expression <1% and ≥1%, the HR (95% CI) was 0.75 (0.52, 1.09) and 0.62 (0.45, 0.87), respectively. Median PFS was 2.8 months in both treatment arms; PFS curves began to separate at 3 months, resulting in a PFS advantage with nivolumab (HR [95% CI]: 0.77 [0.62, 0.95]; P=0.0147). ORR was 17% with nivolumab vs 4% with docetaxel; median duration of response was not reached with nivolumab (95% CI: 11.1 months, not available [NA]) and 5.3 (95% CI: 3.58, NA) months with docetaxel. Rates of grade ≥3 treatment-related adverse events were lower among patients treated with nivolumab (10%) vs docetaxel (48%).

       Conclusions: In this population of patients with advanced NSCLC previously treated with Pt-based chemotherapy, nivolumab demonstrated superior OS, PFS, and ORR compared with docetaxel. Efficacy and safety of nivolumab in this first randomized controlled trial of nivolumab in NSCLC in a predominantly Chinese patient population were consistent with the results of the pivotal global CheckMate 017/057 studies.
