Exclusion Criteria:
- Any previous therapy, including chemotherapy or hormonal or targeted therapy, for inoperable locally advanced or metastatic triple-negative adenocarcinoma of the breast. Participants may have received prior neoadjuvant or adjuvant chemotherapy and/or radiation treatment for locally advanced triple negative adenocarcinoma, provided all treatments were completed greater than or equal to (>/=) 6 months prior to Cycle 1 Day 1. Locally recurrent disease must not be amenable to resection with curative intent
