What was measured

For determining post-baseline incidence, participants were considered to be ADA-positive if they were ADA-negative or had missing data at baseline but developed at least one positive post-baseline ADA result during the randomized phase, or if they were ADA-positive at baseline and the titer of 1 or more post-baseline samples was at least 0.60 titer units (t.u.) greater than the baseline titer result.

Analysis population: ADA-evaluable population was defined as participants with at least one post-dose evaluable ADA sample (collected in the randomized phase).

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.
