NEW YORK – Bristol Myers Squibb said on Wednesday that the three-year follow-up data from the Phase III CheckMate-227 trial showed that non-small cell lung cancer patients with PD-L1 expression levels greater than 1 percent who received the combination of its PD-1 inhibitor nivolumab (Opdivo) and CTLA-4 inhibitor ipilimumab (Yervoy) experienced better outcomes than those who received chemotherapy.
