Summary
This is a Phase III, global, multicenter, open-label, randomized study to compare the
efficacy and safety of 16 cycles (1 cycle duration=21 days) of atezolizumab (MPDL3280A)
treatment compared with best supportive care (BSC) in participants with Stage IB-Stage IIIA
non-small cell lung cancer (NSCLC) following resection and adjuvant chemotherapy, as measured
by disease-free survival (DFS) as assessed by the investigator and overall survival (OS).
Participants, after completing up to 4 cycles of adjuvant cisplatin-based chemotherapy, will
be randomized in a 1:1 ratio to receive atezolizumab for 16 cycles or BSC.
