Brief summary

This multicenter, single-arm study will evaluate the efficacy and safety of atezolizumab (MPDL3280A) in participants with PD-L1-positive locally advanced or metastatic NSCLC. Participants will receive an intravenous (IV) dose of 1200 milligrams (mg) atezolizumab (MPDL3280A) on Day 1 of 21-day cycles until disease progression. Eligible participants will be categorized in to three groups as follows: 1. Participants with no prior chemotherapy for advanced disease; 2. Participants who progress during or following a prior-platinum based chemotherapy regimen for advanced disease (2L+participants); 3. Participants who are 2L+ and previously treated for brain metastases.

Interventions

Modified RECIST was derived from RECIST v1.1 conventions and immune related response criteria. CR was defined as disappearance of all tumor lesions (target lesion \[TL\] and non-target lesion \[non-TL\]) and no new measurable or unmeasurable lesions, all lymph node short axes must be less than 10 millimeters (mm), and PR was defined as at least 30 percent (%) decrease in sum of diameter of TLs and all new measurable lesions since baseline in absence of CR, and both confirmed by consecutive assessment greater than or equal to 4 weeks from date first documented. Participants not meeting these criteria, including participants without at least one post-baseline response assessment were considered as non-responders.

PFS According to Modified RECIST

PFS according to modified RECIST was defined as time from first dose of atezolizumab to first occurrence of documented disease progression or death due to any cause, as determined by investigator for participants who discontinued at first documented radiographic progression. For participants who continued beyond first documented progression and had follow-up tumor assessment or death, PFS was defined as time from first dose of atezolizumab to subsequent radiographic progression or death. For TLs, progressive disease was defined as at least a 20% increase in the sum of diameters of TLs and new measurable lesions, taking as reference the smallest sum recorded since treatment started. In event of no disease progression or documented death, PFS was censored at date of last evaluable tumor assessment.

Time frame: Baseline to the first occurrence of progression or death, whichever occurs earlier (up to 20 months)

Population: Efficacy-evaluable population.

Progression-Free Survival (PFS) According to RECIST v1.1

PFS was defined as time from randomization to first occurrence of documented disease progression (based on RECIST v1.1 criteria) or death due to any cause within 30 days of the last treatment, whichever occurs earlier as determined by investigator. For TLs, progressive disease was defined as at least a 20% increase in the sum of diameter of TLs, taking as reference the smallest sum on study (nadir). For non-TLs, progressive disease was defined as the appearance of 1 or more new lesions and/or unequivocal progression of existing non-TLs. In event of no disease progression or documented death, PFS was censored at date of last evaluable tumor assessment. Participants with no post-baseline tumor assessments were censored at the time of first dose plus 1 day.

Time frame: Baseline to the first occurrence of progression or death, whichever occurs earlier (up to 20 months)

Population: Efficacy-evaluable population.
