pembrolizumab plus SoC (n=410) vs. placebo plus SoC (n=206)
randomized controlled trial
pembrolizumab plus pemetrexed plus platine
200 mg of pembrolizumab every 3 weeks for up to 35 cycles with four cycles of ICC : cisplatin (75 mg per square meter of bodysurface area) or carboplatin (area under the concentration–time curve, 5 mg per milliliter per minute) plus pemetrexed (500 mg per square meter), all administered intravenously every 3 weeks, followed by pemetrexed (500 mg per square meter) every 3 weeks
placebo plus pemetrexed plus platine
four cycles of ICC : cisplatin (75 mg per square meter of bodysurface area) or carboplatin (area under the concentration–time curve, 5 mg per milliliter per minute) plus pemetrexed (500 mg per square meter), all administered intravenously every 3 weeks, followed by pemetrexed (500 mg per square meter) every 3 weeks
placebo-combination group were eligible to cross over to receive pembrolizumab monotherapy.
non squamous - mNSCLC - L1 - Wild Type (WT)
patients with sensitizing EGFR or ALK mutations were excluded
double-blind
126 sites in 16 countries
P3/ one sided and two interim analysis. Repartition, reallocation between coprimary endpoint and hirarchy with secondary endpoint ORR
AI1 stopped/ addition of pembrolizumab to SOC chemotherapy resulted in significantly longer OS and PFS than chemotherapy alone. ORR was also significantly higher in pembrolizumab group.
