Negative change from Baseline values in the GHS/QoL change from baseline analysis indicated deterioration in HRQoL and positive values indicated improvement. |

| Cohort A: Ipatasertib + Paclitaxel | Cohort B: PFS | 9.3 months |
Cohort C: PFS
PFS for Cohort C was defined as the time from enrollment to the first occurrence of disease progression, as determined locally by the investigator through the use of RECIST v.1.1, or death from any cause, whichever occurred first, assessed up to 31 months for this outcome measure. PD was defined as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study, including baseline, in addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. The appearance of one or more new lesions was also considered progression.
Time frame: From enrollment up to 31 months
Population: ITT population included of all enrolled participants in Cohort C.

Cohort A and B: Change From Baseline in Global Health Status (GHS)/Health-Related Quality of Life (HRQoL) Score Measured by GHS/HRQoL Scale (Questions 29 and 30) of the EORTC QLQ-C30
European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) is a cancer-specific instrument with 30 questions covering symptoms, functioning, and health-related quality of life (HRQoL). The participant's assessment of overall HRQoL is assessed by using the last 2 questions (29 and 30) of the instrument, with each of these items based on a 7-point scale (1=very poor to 7=excellent), which are then combined into the GHS/QoL multi-item scale. The scores obtained for each question were averaged into a raw score for the scale, and this raw score for the scale was then subsequently linearly transformed to a scale score of 0 to 100, with a high score indicating better GHS/QoL. Negative change from Baseline values in the GHS/QoL change from baseline analysis indicated deterioration in HRQoL and positive values indicated improvement.
Time frame: Baseline, Day 1 of Cycles 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23 and 24 (cycle length=28 days)
Population: Patient-reported outcome (PRO)-evaluable Population included all randomized (Cohorts A and B) participants who had a baseline and at least 1 postbaseline PRO assessment.Overall number analyzed is the number of participants with data available for analyses. Number analyzed is the number of participants with data available for analysis at the specified time point.

Cohort C: Change From Baseline in GHS/HRQoL Score Measured by GHS/HRQoL Scale (Questions 29 and 30) of the EORTC QLQ-C30
EORTC QLQ-C30 is a cancer-specific instrument with 30 questions covering symptoms, functioning, and health-related quality of life (HRQoL). The participant's assessment of overall HRQoL is assessed by using the last 2 questions (29 and 30) of the instrument, with each of these items based on a 7-point scale (1=very poor to 7=excellent), which are then combined into the GHS/QoL multi-item scale. The scores obtained for each question were averaged into a raw score for the scale, and this raw score for the scale was then subsequently linearly transformed to a scale score of 0 to 100, with a high score indicating better GHS/QoL. Negative change from Baseline values in the GHS/QoL change from baseline analysis indicated deterioration in HRQoL and positive values indicated improvement.
Time frame: Baseline, Day 1 of Cycles 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, and 44 (cycle length=28 days)

| Cohort A: Placebo + Paclitaxel | Cohort C: Number of Participants With Anti-Drug Antibodies (ADAs) to Atezolizumab | 18 Participants |
Cohort C: ORR
ORR was defined as percentage of participants with PR or CR on 2 consecutive occasions ≥4 weeks apart as determined by the investigator using RECIST v.1.1, assessed up to 31 months for this outcome measure. CR was defined as the disappearance of all target lesions or any pathological lymph nodes (whether target or non-target) having a reduction in short axis to \<10 mm. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters. Percentages are rounded off to the nearest decimal point.
Time frame: From enrollment up to 31 months
Population: ITT population consisted of all enrolled participants in Cohort C.

Number of Participants With Adverse Events (AEs)
An AE is any untoward medical occurrence in a participant administered a pharmaceutical product, regardless of causal attribution. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. AEs were reported based on the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), Version 4.0.
Time frame: Up to 58.9 months for Cohort A, up to 59.9 months for Cohort B and up to 45.5 months for Cohort C
Population: Safety Evaluable Population included all participants who received any amount of study treatment.

Number of Participants With at Least One Adverse Events of Special Interest (AESI)
An AE is any untoward medical occurrence in a participant administered a pharmaceutical product, regardless of causal attribution. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events. AEs were reported based on the NCI CTCAE, Version 4.0. AESI include cases of potential drug-induced liver injury that include an elevated alanine aminotransferase (ALT) or aspartate aminotransferase (AST) in combination with either an elevated bilirubin or clinical jaundice, as defined by Hy's Law. Suspected transmission of an infectious agent by the study drug, Grade \>= 3 fasting hyperglycemia, hepatotoxicity, diarrhea, rash, ALT/AST elevations. Grade \>= 2 colitis/enterocolitis.
