Inclusion Criteria

1. Signed ICF prior to participation in any study-related activities
2. Male or female patients=18 years at the time of signing ICF
3. Ability to comply with the study protocol, in the investigator's judgment
4. Histologically confirmed TNBC –regardless of PD-L1 status– per ASCO/CAP criteria based on local testing on the most recent analyzed biopsy. Triple-negative is defined as <1% expression for ER and PgR as determined by IHC,and negative for HER2 (0–1+ by immunohistochemistry [IHC] or 2+ and negative by ISH test)
5. Unresectable locally advanced or metastatic disease documented by CT scan or MRI that is not amenable to resection with curative intent
6. No prior chemotherapy and/or targeted therapy and/or immunotherapy and/or antiangiogenic agent for MBC. Patients who have received (neo)adjuvant taxane-based chemotherapy and/or immunotherapy and/or an antiangiogenic agent are required to have a DFI of at least 12months after completion of each of these treatments. For (neo)adjuvant non-taxane-based chemotherapy, a DFI of at least 6months is required
7. Resolution of all acute toxic effects of prior anti-cancer therapy to grade = 1 as determined by the NCI-CTCAE v.5.0
8. Evidence of measurable disease or non-measurable disease as per RECIST v.1.1. Patients with only bone lesions are also eligible
9. Willingness and ability to provide the most recent tumor biopsy since last progression from either metastatic or primary tissues at the time of the inclusion to perform exploratory studies. If not feasible, patient eligibility should be evaluated by a Sponsor's qualified designee. An additional tumor biopsy from either metastatic or primary (only if metastatic biopsies cannot be obtained for inaccessible lesion or subject safety concern) tissues would be collected at disease progression or study termination whenever it is feasible
10. ECOG Performance Status of 0 or 1
11. Life expectancy of =12 weeks
12. Adequate hematologic and organ function within 14 days before the first study treatment on C1D1, defined by the following parameters:a.Hematological:i.WBC count >3.0x109/L; ii. ANC>1.5 X 109/L; iii. Lymphocyte count 0.5x109/L (500L); iv. Platelet count 75.0x109/L; v. Hemoglobin > 9.0g/dL b. Hepatic: Bilirubin =1.5 times ×ULN (=3xULN in the case of Gilbert's disease); AST and ALT= 2.5×ULN (in the case of liver metastases =5×ULN);ALP=2.5×ULN(=5×ULN in the case of liver and/or bone metastases). c. Serum albumin=2.5g/dL d. Renal: Serum creatinine<1.5×ULN or creatinine clearance=50 mL/min based on Cockcroft-Gault glomerular filtration rate estimation. No proteinuria by dipstick urinalysis (trace proteinuria is allowed). In cases of proteinuria at least 1+ by urinalysis, proteinuria should be less than 500mg by 24-h urine collection. e. Coagulation:For patients not receiving therapeutic anticoagulation: PTT or aPTT and INR=1.5×ULN.For patients receiving therapeutic anticoagulation: stable anticoagulant regimen.
13. Negative HIV test at screening. Patients with a positive HIV test at screening are eligible provided they are stable on anti-retroviral therapy, have a CD4 count ¿ 200/¿L, and have an undetectable viral load.
14. Negative HBsAg test and negative total HBcAb tests at screening, or positive total HBcAb test followed by a negative HBV DNA test at screening. Current treatment with anti-viral therapy for HBV is not allowed.
15. Negative HCV antibody test at screening, or positive HCV antibody test followed by a negative HCV RNA test at s
