7. Serious intercurrent medical or psychiatric illness, including serious active infection
8. History of class II-IV congestive heart failure or myocardial infarction within 6 months of randomization.
9. History of other primary malignancy in the last 5 years. Subjects with prior breast cancer history are eligible, however the most recently obtained biopsy must demonstrate triple negative disease (source documented). Subjects with prior history of in situ cancer or basal or localized squamous cell skin cancer are eligible.
10. Subjects with a history of interstitial lung disease, history of slowly progressive dyspnea and unproductive cough, sarcoidosis, silicosis, idopathic pulmonary fibrosis, pulmonary hypersensitivity pneumonitis or multiple uncontrolled or unstable allergies which, in the opinion of the investigator, may lead to serious complications.
11. Peripheral neuropathy Grade = 2 by NCI CTCAE v4.0
12. Subjects who have received an investigational product within the previous 4 weeks prior to randomization
13. Subject is currently enrolled, or will enroll in a different clinical study in which investigational therapeutic procedures are performed or investigational therapies are administered while participating in this study
14. Pregnant or nursing women
15. Subjects with prior hypersensitivity to nab-paclitaxel, gemcitabine, carboplatin or any other platin, or nucleoside analogue agents
16. Any significant medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from participating in the study
17. Any condition including the presence of laboratory abnormalities, which places the subject at unacceptable risk if she were to participate in the study
18. Any condition that confounds the ability to interpret data from the study
19. History of seropositive human immunodeficiency virus (HIV)
20. Subjects who are receiving immunosuppressive or myelosuppressive medications that would, in the opinion of the investigator, increase the risk of serious neutropenic complications

Primary Outcome(s)

Primary end point(s): Phase II: Progression-Free Survival (PFS) based on investigator assessment of response using RECIST 1.1 guidelines.

Phase III: Progression-Free Survival (PFS) based on an independent blinded radiologist(s) assessment using RECIST 1.1 guidelines.

Secondary Objective: - Phase 2:
? safety
? investigator-determined progression free survival (PFS)
? investigator-determined overall response rate (ORR)
? Overall survival (OS)

- Phase 3:
? Compare safety and tolerability of each treatment regimen
? Compare Overall Response Rate (ORR), determined by independent blinded radiologist(s)
? Compare Overall Survival (OS)
? Compare Disease Control Rate (CR, PR and SD = 16 weeks)
? Compare Duration of Response

Main Objective: - Phase 2: evaluate the benefit and risk profiles of the two nab-paclitaxel experimental arms and identify the nab-paclitaxel combination that will be used in the Phase 3.

- Phase 3: compare the progression-free survival (PFS) of nab-paclitaxel plus carboplatin to gemcitabine/carboplatin in subjects with TNMBC, as assessed by independent blinded radiologist(s) using RECIST 1.1 guidelines.

Timepoint(s) of evaluation of this end point: - in phase II: when approximately 144 PFS events have ocurred

- in phase III: when 330 PFS events or 217 deaths have ocurred, whichever is later

Secondary Outcome(s)

Secondary end point(s): - phase II:
? Efficacy: Overall Response Rate (ORR), investigator-determined, using RECIST 1.1 guidelines; percentage of subjects who initiated Cycle 6; overall Survival
? Safety: Incidence/Grade of TEAEs, serious adverse events (SAEs), laboratory abnormalities; incidence of subjects experiencing dose modifications (dose interruptions and
reductions); percentage of subjects who discontinued for adverse event

- Phase III:
key secondary endpoints: ORR with a confirmed complete or partial response; OS;
others: efficacy (investigator assessment of PFS; disease control rate; duration of response in subjects with objective CR or PR), safety (incidence of TEAEs, SAEs, laboratory abnormalities)

Timepoint(s) of evaluation of this end point: phase II: efficacy and safety at cut-off date of follow-up period

phase III: efficacy and safety at cut-off date of follow-up period; final analysis of overall survival after approximately 309 deaths
