Overall survival was significantly longer for pembrolizumab 2 mg/kg versus docetaxel (hazard ratio 0.71, 95% CI 0.58-0.88 p=0.0008) and for pembrolizumab 10 mg/kg versus docetaxel (0.61, 0.49-0.75 p<0.0001). In the total population, median overall survival was 10.4 months with pembrolizumab 2 mg/kg, 12.7 months with pembrolizumab 10 mg/kg, and 8.5 months with docetaxel.
010 EDITOR JAPANESE BLOCKS TRIAL
This trial is registered at, number NCT01905657.īetween Aug 28, 2013, and Feb 27, 2015, we enrolled 1034 patients: 345 allocated to pembrolizumab 2 mg/kg, 346 allocated to pembrolizumab 10 mg/kg, and 343 allocated to docetaxel. We used a threshold for significance of p<0.00825 (one-sided) for the analysis of overall survival and a threshold of p<0.001 for progression-free survival. The primary endpoints were overall survival and progression-free survival both in the total population and in patients with PD-L1 expression on at least 50% of tumour cells. Patients with previously treated non-small-cell lung cancer with PD-L1 expression on at least 1% of tumour cells were randomly assigned (1:1:1) in blocks of six per stratum with an interactive voice-response system to receive pembrolizumab 2 mg/kg, pembrolizumab 10 mg/kg, or docetaxel 75 mg/m(2) every 3 weeks. We did this randomised, open-label, phase 2/3 study at 202 academic medical centres in 24 countries. We assessed the efficacy of pembrolizumab for patients with previously treated, PD-L1-positive, advanced non-small-cell lung cancer.
