PFS is defined as the time from randomization to the first documented disease progression as determined by the investigator with the use of RECIST v1.1, or death from any cause, whichever occurs first.

OS is defined as the time from randomization to death due to any cause.

Objective response rate (ORR) is defined as the proportion of participants with a confirmed objective response, either complete response (CR) or partial response (PR), observed on two assessments \>= 28 days apart per RECIST v1.1, based on investigator assessment. The analysis population for ORR will be all randomized participants with measurable disease at baseline.

Duration of response (DOR) is defined for participants with an objective response as the time from the first documented objective response to documented disease progression per RECIST v1.1, based on investigator assessment, or death due to any cause, whichever occurs first.

Independent review facility PFS (IRF-PFS) is defined as the time from randomization to the first documented disease progression as determined by blinded independent central review with use of RECIST v1.1, or death due to any cause, whichever occurs first.

Serious \& other adverse events reported based on safety population, which included patients who received any amount of any component of study treatment. There were 6 patients randomized to Atezo monotherapy after approval of Protocol version 6 who received open-label Atezo and chemo, and were pooled with patients in Atezo+chemo for safety analyses. All-cause mortality reported for deaths that occurred during study based on ITT, which included all randomized patients.

Participants received blinded placebo matched to atezolizumab in combination with open-label platinum-based chemotherapy (gemcitabine with either cisplatin or carboplatin).
