Exclusion criteria

The subject must be excluded from participating in the trial if the subject has/is:

  1. Malignancies other than breast cancer within 5 years prior to randomization, with the exception of those with a negligible risk of metastasis or death and treated with expected curative outcome (such as adequately treated carcinoma in situ of the cervix or basal or squamous cell skin cancer)
  2. Spinal cord compression not definitively treated with surgery and/or radiation, or previously diagnosed and treated spinal cord compression without evidence that disease has been clinically stable for > 8 weeks prior to randomization
  3. Known CNS disease, except for treated asymptomatic CNS metastases, provided all of the following criteria are met:
    1. Measurable disease outside the CNS
    2. Asymptomatic for CNS disease > 4 months.
    3. Only supratentorial metastases allowed
    4. No evidence of progression after completion of CNS-directed therapy
    5. No ongoing requirement for dexamethasone as therapy for CNS disease
    6. No radiation of brain lesions within 4 months prior to randomization

  4. Known BRCA mutation, unless the patient has already received carboplatin or for other reasons should not receive carboplatin treatment, according to own preferences or reccommendations by the treating physician.
  5. Uncontrolled pleural effusion, pericardial effusion, or ascites. Patients with indwelling catheters (e.g., PleurX®) are allowed
  6. Uncontrolled tumor-related pain. Patients requiring narcotic pain medication must be on a stable regimen at study entry. Symptomatic lesions (e.g., bone metastases or metastases causing nerve impingement) amenable to palliative radiotherapy should be treated prior to randomization. Asymptomatic metastatic lesions whose further growth would likely cause functional deficits or intractable pain (e.g., epidural metastasis that is not presently associated with spinal cord compression) should be considered for loco-regional therapy if appropriate prior to randomization
  7. Ionized calcium > 1.2 x UNL. The use of bisphosphonates is allowed
  8. Pregnant or breastfeeding
  9. Evidence of significant uncontrolled concomitant disease that could affect compliance with the protocol or interpretation of results, including significant liver disease (such as cirrhosis, uncontrolled major seizure disorder, or superior vena cava syndrome)
  10. Significant cardiovascular disease, such as New York Heart Association (NYHA) cardiac disease (Class II or greater), myocardial infarction within 3 months prior to randomization, unstable arrhythmias, or unstable angina Patients with a known left ventricular ejection fraction (LVEF) < 40% will be excluded. Patients with known coronary artery disease, congestive heart failure not meeting the above criteria, or LVEF < 50% must be on a stable medical regimen that is optimized in the opinion of the treating physician, in consultation with a cardiologist if appropriate
  11. Severe infection within 21 days prior to randomization, requiring hospitalization
  12. Received oral or IV antibiotics within 1 week prior to Cycle 1, Day 1. Patients receiving routine antibiotic prophylaxis (e.g., to prevent chronic obstructive pulmonary disease exacerbation or for dental extraction) are eligible
  13. Major surgical procedure within 21 days prior to randomization or anticipation of the
need for a major surgical procedure during the course of the study other than for diagnosis. Placement of central venous access catheter(s) is not considered a major surgical procedure and is therefore permitted
  14. A history of severe allergic, anaphylactic, or other hypersensitivity reactions to chimeric or humanized antibodies or fusion proteins
  15. Known hypersensitivity to any of the components of the investigational products
  16. A history of autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (e.g., thyroxin, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
Patients with eczema, psoriasis, lichen simplex chronicus or vitiligo with dermatologic manifestations only (e.g., no psoriatic arthritis) are permitted provided that they meet all of the following conditions:
    1. Rash must cover less than 10% of body surface area.

Patients with past hepatitis B virus (HBV) infection or resolved HBV infection (defined as having a negative HBsAg test and a positive antibody to hepatitis B core antigen [anti-HBc] antibody test) are eligible. Patients positive for hepatitis C virus (HCV) antibody are eligible only if polymerase chain reaction (PCR) is negative for HCV RNA
  21. Active tuberculosis
  22. Currently receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of treatment
  23. Received treatment with immune checkpoint modulators, including anti−CTLA-4, anti−PD-1, or anti−PD-L1 therapeutic antibodies

  27. A history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject’s participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating Investigator
  28. Known psychiatric or substance abuse disorders that would interfere with cooperation and the requirements of the trial
  29. Received a live vaccine within 30 days of planned start of study therapy, or is expected to receive such a vaccine while on therapy
