What was measured

EORTC QLQ-C30=30 questions assessing 5 aspects of participant functioning(physical,emotional,role,cognitive \&social),3 symptom scales,GHS/QoL \& 6 single items.PF scale=5 questions about participants PF \& daily activities(strenuous activities,long walks,short walks,bed/chair rest \& needing help with eating,dressing,washing themselves/using the toilet).PF scale scored on 4-point scale(1=Not at All-4=Very Much).GHS/QoL scored on 7-point scale(1=Very Poor- 7=Excellent).Scores were linearly transformed to a range of 0-100,higher scores=higher response level \& better QoL.TTCD for PF \& GHS/QoL=time from the date of randomization until first confirmed clinically meaningful deterioration,which is decrease from baseline in PF/GHS score that must be held for at least 2 consecutive assessments/initial decrease above baseline followed by death attributable to cancer progression within 6 weeks of the last deteriorated assessment.Score change≥10-point change in subscale score,considered meaningful.

Analysis population: FAS included all participants randomized into the randomized phase, regardless of whether or not the assigned study treatment was received.

Groups in this outcome

Atezolizumab

Participants received atezolizumab, 1200 mg, Q3W as IV infusion on Day 1 of each 21-day cycle until unacceptable toxicity or PD whichever occurred first.

Atezolizumab+ Lurbinectedin

Participants received atezolizumab, 1200 mg, Q3W as IV infusion and lurbinectedin, 3.2 mg/m\^2, Q3W as IV infusion on Day 1 of each 21-day cycle until unacceptable toxicity or PD whichever occurred first.
