What was measured

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.

Analysis population: The duration of response (DOR)-evaluable population is defined as participants with an objective response in the the ITT population which included only participants concurrently enrolled in Stage 2 and only those who had been randomized at the time of approval of Protocol WO30070 v6.

Groups in this outcome

Placebo+Gemcitabine+Carboplatin/Cisplatin

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

Atezolizumab Monotherapy

Eligible participants received open-label atezolizumab as monotherapy.
