What was measured

Median time to deterioration in physical function as measured by the QLQ-C30 in the Placebo+Gemcitabine+Carboplatin/Cisplatin Arm versus Atezolizumab Monotherapy Arm.

Analysis population: Evaluable population defined as patients in ITT for comparisons of Placebo+Chemo vs. Atezo Mono who have a baseline and at least one post-baseline assessment. ITT for comparison of Atezo Mono vs. Placebo+Chemo consisted of 360 patients enrolled in Atezo Mono in Stage 2. Although a total of 400 patients were randomized to Placebo+Chemo throughout study, only 359 patients who were concurrently enrolled into this arm in Stage 2 and prior to Protocol v6 were included in Placebo+Chemo of this ITT.

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.
