Inclusion Criteria
  1. Histologically confirmed invasive breast cancer by core needle or incisional biopsy (excisional biopsy is not allowed). Clinical stage T2-3 N0-2 or T1 N1-2 by physical exam or radiologic studies.
  2. Documented Breast Cancer Gene (BRCA) germline mutation testing.
  3. Estrogen Receptor (ER)-, Progesterone Receptor (PR)-, and Human Epidermal Growth Factor Receptor (HER)2-negative (triple-negative) cancer of the breast.
  4. ECOG Performance status of 0 to 1.
  5. Women must be determined to be not of childbearing potential (surgically sterile, or postmenopausal defined as amenorrheic for at least 12 months) by the Investigator OR they must have a negative serum pregnancy test prior to randomization.
Exclusion Criteria
  1. Previous anti-cancer treatment (cytotoxic chemotherapy, immunotherapy, biologic therapy radiotherapy or investigational agents) with therapeutic intent for current breast cancer.
  2. Previous treatment with carboplatin, paclitaxel, doxorubicin, cyclophosphamide and a Poly-(ADP-ribose)-Polymerase (PARP) inhibitor.
  3. Concurrent treatment with an ovarian hormonal replacement therapy or with hormonal agents such as raloxifene, tamoxifen or other selective estrogen receptor modulator (SERM). Subjects must have discontinued use of such agents prior to beginning study treatment.

Primary Outcome Measures
NameTimeMethod
Pathological Complete Response (pCR).At the time of definitive surgery (approximately 24-36 weeks from first dose of study drug).

Pathological complete response (pCR) in the breast tissue and the lymph node tissue will be assessed upon completion of pre-operative systemic therapy and definitive surgery.

Secondary Outcome Measures
NameTimeMethod
Event Free Survival (EFS)Up to 4 years from the date of definitive surgery.

EFS will be defined as the time from random assignment to documentation of the first of the following events: discontinuation of study therapy due to protocol-defined progression prior to surgery; local, regional, or distant recurrence of breast cancer following curative surgery; a new breast cancer; another new onset malignancy; or death as a result of any cause.

Overall Survival (OS)Up to 4 years from the date of definitive surgery.

OS will be defined as the number of days from the day the subject is randomized to the date of the subject's death.

Rate of eligibility for breast conservation after therapy (BCR).At the time of definitive surgery (approximately 24-36 weeks from first dose of study drug).

Whether a subject is eligible for breast conserving surgery for whom mastectomy was planned at diagnosis will be determined by the subject's surgeon prior to chemotherapy and after completion of chemotherapy.
