Brief summary

This multicenter, single-arm study will evaluate the efficacy and safety of Atezolizumab in participants with PD-L1-positive locally advanced or metastatic non-small cell lung cancer (NSCLC). Participants will receive Atezolizumab 1200 milligrams (mg) intravenously every 3 weeks as long as participants are experiencing clinical benefit as assessed by the investigator, that is , in the absence of unacceptable toxicity or symptomatic deterioration attributed to disease progression.

DOR as Assessed by INV Per Modified RECIST

DOR is the interval between the date of the first occurrence of a CR or PR that is subsequently confirmed (whichever status is recorded first) and the first date that PD or death is documented, whichever occurs first as measured by modified RECIST. CR: disappearance of all target lesions. Any pathological lymph nodes (target or non-target) must have reduction in short axis to \<10mm; PR: at least a 30% decrease in the sum of the diameters of all target and all new measurable lesions, taking as reference the baseline sum of diameters, in the absence of CR; PD: one or more of the following: at least 20% increase from nadir in the sum of diameters of existing and/or new target lesions (with an absolute increase of at least 5mm). DOR was assessed by Kaplan-Meier estimates. Results were reported by line of therapy (reporting arms) and PD-L1 Expression Subgroup (TC3 or IC3, TC3 or IC2/3, TC2/3 or IC2/3).

Time frame: Screening, Every 6 weeks (± 3 days) for 12 months following Cycle 1, Day 1 and every 9 weeks (± 1 week) thereafter until disease progression, intolerable toxicity or death until data cut-off on 28 May 2015 (Up to 16 months)

DOR as Assessed by INV Per RECIST v1.1

DOR is interval between date of the first occurrence of a CR or PR that is subsequently confirmed (whichever status is recorded first) and first date that PD or death is documented, whichever occurs first as measured by RECIST v1.1. CR: disappearance of all target and non-target lesions. Any pathological lymph nodes (target or non-target) must have reduction in short axis to \<10mm; PR: \> or = 30 % decrease from baseline in sum of diameters of target lesions, non-PD non-target lesions and no new lesions; PD: one or more of the following: at least 20% increase from nadir in sum of diameters of target lesions (with an absolute increase of at least 5mm), appearance of new lesions, and/or unequivocal progression of non-target lesions. DOR was assessed by Kaplan-Meier estimates. Results were reported by line of therapy (reporting arms) and PD-L1 Expression Subgroup (TC3 or IC3, TC3 or IC2/3, TC2/3 or IC2/3).

Time frame: Screening, Every 6 weeks (± 3 days) for 12 months following Cycle 1, Day 1 and every 9 weeks (± 1 week) thereafter until disease progression, intolerable toxicity or death until data cut-off on 28 May 2015 (Up to 16 months)

Population: Efficacy evaluable population; n = number of participants analyzed within the specified group. Number of participants analyzed = overall number of participants who were evaluable for this outcome.

Percentage of Participants With Positive Anti-Therapeutic Antibody (Anti-Atezolizumab Antibody) Status

Anti-therapeutic antibodies is a measurement to explore the potential relationship of immunogenicity response with pharmacokinetics, safety and efficacy.

Time frame: Baseline, post-baseline (up to 16 months)

Population: Efficacy evaluable population; n = number of participants analyzed at the specified time point. Number of participants analyzed = number participants who were evaluable for this outcome.

PFS as Assessed by INV Per Modified RECIST

PFS is the interval between the first dose of atezolizumab and date of disease progression or death due to any cause, whichever occurred first as measured by modified RECIST. PD: at least 20% increase from nadir in the sum of diameters of new and/or existing target lesions (with an absolute increase of at least 5mm). PFS was assessed by Kaplan-Meier estimates.

Time frame: Screening, Every 6 weeks (± 3 days) for 12 months following Cycle 1, Day 1 and every 9 weeks (± 1 week) thereafter until disease progression, intolerable toxicity or death until data cut-off on 28 May 2015 (Up to 16 months)

Population: Efficacy evaluable population; n = number of participants analyzed within the specified group.

Time in Response (TIR) as Assessed by INV Per RECIST v1.1

TIR is interval between date of first occurrence of a CR or PR that is subsequently confirmed (whichever status is recorded first) and first date that PD or death is documented, whichever occurs first as measured by RECIST v1.1. For responders, TIR was the same as DOR; for non-responders, TIR was considered as an event and defined as the date of first treatment plus one day. TIR was assessed by Kaplan-Meier estimates.
