In the dual group, patients with PD-L1 TPS 0-20% had significantly longer PFS (10.5 months (5.0-NA) vs. 4.1 months (0.23-NA), p=0.017) and OS (NA months (18.6-NA) vs. 9.0 months (0.23-NA), p=0.0014) than those with PD-L1 TPS 21-49%....The results suggest that nivolumab and ipilimumab-based therapy may be a better treatment option, especially for patients with negative and lower PD-L1 TPS (<20%).
