Brief summary
This is a single center non-blinded randomized multi-cohort non-comparative phase II trial with a Simon's two-stage design.
Detailed description
In the first stage, 13 evaluable patients will be accrued per cohort. Evaluable is defined as: at least one administration of nivolumab and availability of paired biopsies for immunohistochemistry (for induction treatment cohorts pre-induction and pre-nivolumab biopsies). If there are 1 or no responses observed in these 13 patients, the cohort will be stopped. Otherwise, 21 additional patients will be accrued for a total of 34.
Interventions
240 mg flat-dose, every 2 weeks. From 20 weeks onwards, nivolumab will be administered every 4 weeks with a flat-dose of 480 mg starting from week 20 onwards
40mg/m2, weekly for two weeks
15mg flat dose, weekly for 8 weeks

Eligibility
Inclusion criteria
* Metastatic or incurable locally advanced triple negative breast cancer (ER \< 10%, HER2 IHC 0,1+ or 2+ with no amplification) * Metastatic lesion accessible for histological biopsy * 18 years or older * Maximum of three lines of chemotherapy for metastatic disease and with evidence of progression of disease. Treatment with low-dose doxorubicin in the palliative setting is not allowed. * WHO performance status of 0 or 1 * Measurable or evaluable disease according to RECIST 1.1 * Disease Free Interval (defined as time between first diagnosis or locoregional recurrence and first metastasis) longer than 1 year * Subjects with brain metastases are eligible if these are not symptomatic and free of progression of at least 4 weeks * A maximum dosage of 360 mg/m2 of anthracyclines and no previous anthracycline-related cardiac toxicity. In case of radiation in the cardiac area, hypertension, diabetes mellitus or hypercholesterolemia, the left ventricular ejection fraction must be 50% or higher. * Adequate bone marrow, kidney and liver function
Exclusion criteria
* uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris * known history of leptomeningeal disease localization * history of having received other anticancer therapies within 2 weeks of start of the study drug * history of immunodeficiency, autoimmune disease, conditions requiring immunosuppression (\>10 mgl daily prednisone equivalents) or chronic infections. * prior treatment with immune checkpoint inhibitors. * active other cancer * history of uncontrolled serious medical or psychiatric illness * current pregnancy or breastfeeding
