Brief Summary:
This multicenter, randomized, double-blind study will evaluate 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.

Condition or disease Intervention/treatment Phase
