Inclusion criteria
Inclusion criteria: 1. Be willing and able to provide written informed consent for the trial. The subject may also provide consent for Future Biomedical Research. However, the subject may participate in the main trial without participating in Future Biomedical Research. 2.Be a male or female subject >18 years of age on day of signing informed consent. 3.Have centrally confirmed TNBC, as defined by the most recent ASCO/CAP guidelines. 4.Have previously untreated locally advanced non-metastatic (M0) TNBC defined as the following combined primary tumor (T) and regional lymph node (N) staging per AJCC for breast cancer staging criteria version 7 as assessed by the investigator based on radiological and/or clinical assessment: T1c, N1-N2, T2, N0-N2, T3, N0-N2,T4a-d, N0-N2 5.Provide a core needle biopsy consisting of at least 2 separate tumor cores from the primary tumor at screening to the central laboratory. 6.Have Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 performed within 10 days of treatment initiation. 7.Demonstrate adequate organ function as defined in the protocol. All screening labs should be performed within 10 days of treatment initiation. 8.Have left ventricular ejection fraction (LVEF) of =50% or = institution lower limit of normal (LLN) as assessed by echocardiogram (ECHO) or multigated acquisition (MUGA) scan performed at screening. 9.Males and female subjects of childbearing potential must be willing to use an adequate method of contraception. Contraception, for the course of the study through 12 months after the last dose of study medication for subjects who have received cyclophosphamide, and 6 months after the last dose of study medication for subjects who did not. 10.(Female subject of childbearing potential) Have a negative urine or serum p regnancy test within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or borderline a serum pregnancy test will be required. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 1075 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 75
Exclusion criteria
Exclusion criteria: 1.Has a history of invasive malignancy =5 years prior to signing informed consent except for adequately treated basal cell or squamous cell skin cancer or in situ cervical cancer. 2. Has received prior chemotherapy, targeted therapy, and radiation therapy within the past 12 months. 3. Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent or with an agent directed to another co-inhibitory T-cell receptor (e.g., CTLA-4, OX-40, CD137) or has previously participated in MK-3475 clinical trials. 4. Is currently participating in or has participated in an interventional clinical trial with an investigational compound or device within 4 weeks of the first dose of treatment in this current trial. 5.Has received a live vaccine within 30 days of the first dose of study treatment. 6.Has an active autoimmune disease that has required systemic treatment in past 2 years (i.e., with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment. 7. Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy (ie, dosing exceeding 10 mg daily of prednisone or equivalent) within 7 days prior to the first dose of trial treatment. 8. Has a known history of Human Immunodeficiency Virus (HIV) (HIV 1/2 antibodies). 9. Has known active Hepatitis B (e.g., HBsAg reactive) or Hepatitis C (e.g., HCV RNA [qualitative] is detected). 10. Has a history of (non-infectious) pneumonitis that required steroids or current pneumonitis. 11. Has an active infection requiring systemic therapy. 12.Has significant cardiovascular disease, such as: a) History of myocardial infarction, acute coronary syndrome or coronary angioplasty/stenting/bypass grafting within the last 6 months b) Congestive heart failure (CHF) New York Heart Association (NYHA) Class II-IV or history of CHF NYHA class III or IV 13. Has a history or current evidence of any condition, therapy, lab abnormality or other circumstance that might expose the subject to risk by participating in the trial, confound the results of the trial, or interfere with the subject’s participation for the full duration of the trial. 14. Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial. 15. Is pregnant or breastfeeding, or expecting to conceive children within the projected duration of the trial, starting with the screening visit through 12 months after the last dose of trial treatment for subjects who have received cyclophosphamide, and for 6 months after the last dose of study medication for subjects who have not. 16. Has a known hypersensitivity to the components of the study therapy or its analogs. 17. Has a known history of active TB (Bacillus Tuberculosis)

| Measure | Time frame |

| Main Objective: 1. To evaluate the rate of pCR using the definition of ypT0/Tis ypN0 (i.e., no invasive residual in breast or nodes; noninvasive breast residuals allowed) as assessed by the local pathologist at the time of definitive surgery in subjects with locally advanced TNBC 2.To evaluate the event-free survival (EFS) as assessed by Investigator in subjects with locally advanced TNBC.;Secondary Objective: 1. To evaluate overall survival (OS) in subjects with locally advanced TNBC tumors. 2. To evaluate the rate of pCR using an alternative definition, ypT0 ypN0 (i.e., no invasive or noninvasive residual in breast or nodes) as assessed by the local pathologist at the time of definitive surgery in subjects with locally advanced TNBC and in individuals with programmed death ligand1 (PD-L1) positive (+) tumors (combined positive score [CPS] =1). 3. To evaluate the rate of pCR using the definition of (ypT0/Tis ypN0) (i.e., no invasive residual in breast or nodes; noninvasive breast residuals allowed) as assessed by the local pathologist at the time of definitive surgery in individuals with PD-L1 (+) tumors (CPS =1). 4. To evaluate the EFS as assessed by Investigator in individuals withPDL1 (+) tumors (CPS =1). For a complete list of all secondary objectives, please refer to the protocol. ;Primary end point(s): 1.Pathological complete response rate (ypT0/Tis ypN0) in subjects with locally advanced TNBC. 2. Event-free survival (EFS) in subjects with locally advanced TNBC.;Timepoint(s) of evaluation of this end point: After Definitive Surgery and at any point PD/Recurrance occurs | — |
