Tumor response was assessed by the investigator according to modified RECIST. CR was defined as disappearance of all target and non-target lesions and no new measurable or unmeasurable lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \\<10 mm. PR was defined as ≥30% decrease in sum of LD of target lesions in reference to Baseline sum LD. Disease progression or PD was defined as ≥20% increase in sum LD in reference to the smallest on-study sum LD. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. Response was to be confirmed ≥4 weeks after the initial assessment of CR or PR.","dispersionType":"Full Range","groups":[{"description":"Participants who had disease progression during or following treatment with at least one platinum-containing chemotherapy regimen in the metastatic setting received atezolizumab 1200 mg via IV infusion on Day 1 of 21-day cycles until loss of clinical benefit or unmanageable toxicity.","id":"OG000","title":"Cohort 2: Participants With Second-line or Beyond Treatments"}],"paramType":"MEDIAN","populationDescription":"Cohort 2 objective response-evaluable population.
