Who may be able to join
- Participants must have histologically or cytologically confirmed invasive breast cancer, with unresectable locally advanced or metastatic disease. Participants without pathologic or cytologic confirmation of metastatic disease should have unequivocal evidence of metastasis from physical examination or radiologic evaluation.
- Estrogen-receptor and progesterone-receptor expression both ≤ 1% by immunohistochemistry (IHC), and HER2-negative status as determined by the current ASCO/CAP guidelines. If a patient has more than one histological result, the most recent sample will be considered for inclusion.
- Participants must have PD-L1 status available at the time of registration. Standard local testing with any PD-L1 antibody that has been validated in a CLIA-certified environment will be acceptable for including patients on trial.. Primary or metastatic samples may be tested for PD-L1 status.
- Participants must have measurable or evaluable disease by RECIST version 1.1.
- Participants must agree to undergo a research biopsy, if tumor is safely accessible, at baseline. Previously collected archival tissue will also be obtained on all participants. For participants for whom newly-obtained samples cannot be provided (e.g. inaccessible or participant safety concern) the archival tissue alone will be acceptable. Tissue needs to be located and availability confirmed at time of registration (See Section 9 for more details). Participants must agree to a mandatory repeat biopsy 3-6 weeks after starting treatment, if tumor is safely accessible. For patients randomized to carboplatin alone who decide to crossover to nivolumab and nab-paclitaxel at time of progression, a mandatory biopsy will be required if tumor is safely accessible prior to initiating crossover treatment; participants must also agree to undergo this biopsy, if applicable.
- Prior chemotherapy: Participants must have received 0 prior chemotherapeutic regimens for metastatic breast cancer. Prior platinum in the neo/adjuvant setting is permissible, if at least 6 months elapsed since the end of adjuvant systemic therapy to the development of metastatic disease. All toxicities related to prior chemotherapy must have resolved to CTCAE v4.0 grade 1 or lower, unless otherwise specified.

- Prior biologic therapy: Prior poly-ADP ribose polymerase (PARP) inhibitors are not allowed in the metastatic setting. Prior PARP inhibitors in the neo/adjuvant setting are permissible, if at least 6 months elapsed since the end of adjuvant systemic therapy to the development of metastatic disease. All toxicities related to prior biologic therapy must have resolved to CTCAE v4.0 grade 1 or lower, unless otherwise specified.
- Prior radiation therapy: Patients may have received prior radiation therapy. Radiation therapy must be completed at least 14 days prior to registration, and all toxicities related to prior radiation therapy must have resolved to CTCAE v4.0 grade 1 or lower, unless otherwise specified in 3.1.10. Patients may not have had >25% of their bone marrow radiated.

- Women of childbearing potential (WOCBP) must agree to use an adequate method of contraception. Contraception is required starting with the first dose of study medication through 150 days (5 months) after the last dose of study medication. Examples of contraceptive methods with a failure rate of < 1% per year include bilateral tubal ligation, male sterilization, established and proper use of hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception.
- Males who are sexually active with WOCBP must agree to follow instructions for method(s) of contraception for the duration of study treatment with nivolumab and 7 months after the last dose of study treatment (i.e., 90 days (duration of sperm turnover) plus the time required for the investigational drug to undergo approximately five half-lives.)
- Participants on bisphosphonates or RANK ligand inhibitors may continue receiving therapy during study treatment.

Treated brain metastases are defined as those without ongoing requirement for corticosteroids, as ascertained by clinical examination and brain imaging (magnetic resonance imaging or CT scan) completed during screening. Any corticosteroid use for brain metastases must have been discontinued without the subsequent appearance of symptoms for ≥7 days prior to registration. Treatment for brain metastases may include whole brain radiotherapy, radiosurgery, surgery or a combination as deemed appropriate by the treating physician. Radiation therapy must be completed at least 7 days prior to registration
- Major surgery within 2 weeks prior to registration. Patients must have recovered from any effects of any major surgery.
- Uncontrolled, significant intercurrent or recent illness including, but not limited to, ongoing or active infection, uncontrolled non-malignant systemic disease, uncontrolled seizures, or psychiatric illness/social situation that would limit compliance with study requirements in the opinion of the treating investigator.

- Participant has a medical condition that requires chronic systemic steroid therapy (> 10 mg of prednisone daily or equivalent) or any other form of immunosuppressive medication (including disease modifying agents) and has required such therapy in the last 2 years. Replacement therapy (eg., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic therapy.
- Participant has documented history of autoimmune disease or syndrome that currently requires systemic steroids or immunosuppressive agents.

About this study
Official title: A Randomized Phase II Trial of Carboplatin With or Without Nivolumab in First-line Metastatic Triple-negative Breast Cancer
This research study is studying a drug called Carboplatin with or without another study drug, Nivolumab as a possible treatment for triple-negative breast cancer that has spread to other parts of the body.
The interventions involved in this study are:
- Carboplatin
- Nivolumab
Read the detailed description
This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational intervention to learn whether the intervention works in treating a specific disease. "Investigational" means that the intervention is being studied.
The FDA (the U.S. Food and Drug Administration) has not approved nivolumab for your specific disease but it has been approved for other uses. The FDA has approved carboplatin as a treatment option for your disease.
The purpose of this research study is to determine how well carboplatin, by itself, or together with nivolumab, works in treating breast cancer that has spread to other parts of the body. Nivolumab is a recently discovered human monoclonal antibody. An antibody is a type of protein that your immune system (the system that defends your body against potentially harmful particles) uses to find and destroy foreign molecules (particles not typically found in your body, such as bacteria and viruses). Scientists can now make antibodies in the laboratory and produce them for the treatment of many different diseases.
Nivolumab works by attaching to and blocking a molecule called PD-1. PD-1 is a different molecule that can turn off the immune system by interacting with PD-L1 on the cancer cell. Nivolumab has been shown in research studies to prevent PD-1 from shutting down the immune system, thus allowing it to recognize and help your body destroy the cancer cells. You are being asked to participate in this study because triple-negative breast cancer has shown elevated rates of PD-L1 expression.
Nivolumab has been used in other research studies and information from those research studies suggests that nivolumab may help shrink or stabilize your triple negative breast cancer in this study
