  PFS was defined as the time from randomization to the occurrence of disease progression, as determined by investigators from tumor assessments per RECIST v1.1, or death from any cause, whichever occurred first.
• PFS According to RECIST v1.1 in Participants With Detectable Programmed Death-Ligand 1 (PD-L1) [ Time Frame: Baseline up to approximately 34 months ]
  PFS was defined as the time from randomization to the occurrence of disease progression, as determined by investigators from tumor assessments per RECIST v1.1, or death from any cause, whichever occurred first.
• Overall Survival (OS) in All Randomized Participants [ Time Frame: Baseline until death due to any cause (up to approximately 58 months) ]
  OS was defined as the time from the date of randomization to the date of death from any cause.
• OS in Participants With Detectable PD-L1 [ Time Frame: Baseline until death due to any cause (up to approximately 58 months) ]
  OS was defined as the time from the date of randomization to the date of death from any cause.

  An objective response was defined for participants with measurable disease at baseline as either a partial response (PR) or a complete response (CR) using RECIST v1.1.
• Duration of Response (DOR) According to RECIST v1.1 in All Randomized Participants [ Time Frame: Baseline up to approximately 34 months ]
  DOR was defined for participants who had an objective response as the time from the first occurrence of a documented unconfirmed response (CR or PR) to the date of disease progression per RECIST v1.1 or death from any cause, whichever occurred first.
• DOR Acccording to RECIST v1.1 in Participants With Detectable PD-L1 [ Time Frame: Baseline up to approximately 34 months ]
  DOR was defined for participants who had an objective response as the time from the first occurrence of a documented unconfirmed response (CR or PR) to the date of disease progression per RECIST v1.1 or death from any cause, whichever occurred first.

  Deterioration in GHS/HRQoL (Items 29, 30 of the EORTC QLQ C30) was defined by the following two criteria: 1. The time from randomization to the first time the participant's GHS/HRQoL scale score showed a >=10-point decrease from the baseline scale score. A 10-point change was defined as the minimally important difference (MID). 2. The score decrease of >= 10-points from baseline was held for at least two consecutive cycles, or an initial score decrease of >= 10-points was followed by death or treatment discontinuation within 3 weeks from the last assessment.
• TTD in Global Health Status/Health Related Quality of Life According to EORTC QLQ-C30 v3.0 in Participants With Detectable PD-L1 [ Time Frame: Baseline up to approximately 58 months ]
  Deterioration in GHS/HRQoL (Items 29, 30 of the EORTC QLQ C30) was defined by the following two criteria: 1.

Descriptive Information

• Brief Title: A Study of Atezolizumab in Combination With Nab-Paclitaxel Compared With Placebo With Nab-Paclitaxel for Participants With Previously Untreated Metastatic Triple-Negative Breast Cancer (IMpassion130)
• Official Title: A Phase III, Multicenter, Randomized, Placebo-Controlled Study of Atezolizumab (Anti-PD-L1 Antibody) in Combination With Nab-Paclitaxel Compared With Placebo With Nab-Paclitaxel for Patients With Previously Untreated Metastatic Triple-Negative Breast Cancer
• Brief Summary: This multicenter, randomized, double-blind study evaluated the efficacy, safety, and pharmacokinetics of atezolizumab (MPDL3280A) administered with nab-paclitaxel compared with placebo in combination with nab-paclitaxel in participants with locally advanced or metastatic triple-negative breast cancer (TNBC) who have not received prior systemic therapy for metastatic breast cancer (mBC). The safety of single-agent nab-paclitaxel has been determined in previous studies of participants with mBC and the safety data to date suggest that atezolizumab can be safely combined with standard chemotherapy agents.
