Age of ≥ 18 years
Provision of an archived FFPE diagnostic biopsy or surgical primary tumour sample (or at least 20 unstained slides, freshly cut for the purposes of the study). In case of neoadjuvant treatment (before surgery), the diagnostic biopsy is preferable.
At least 6 months elapsed between the completion of surgical and/or systemic treatment with curative intent (e.g., the date of primary breast tumour surgery or the date of last adjuvant chemotherapy administration (radiotherapy is not included), whichever occurred last) and first documented local or distant disease recurrence (NOTE: not applicable for de-novo metastatic disease)
At least one measurable disease based on RECIST v1.1. Tumour lesions in a previously irradiated area are considered measurable, if progression has been demonstrated in such lesions
Adequate organ function: a) Absolute neutrophil count (ANC) ≥ 1500/µl (without the addition of growth factors) b) Platelets [PLT] ≥ 100000/µl (without the addition of growth factors/prior transfusions) c) Hemoglobin (Hb) ≥ 10 g/dl (without the addition of growth factors/prior transfusions) d) Creatinine ≤ 1.5 x upper limit of normal (ULN) OR estimated glomerular filtration rate (eGFR) ≥ 60 ml/min as calculated using the method standard for the institution. If eGFR is lower than 60 ml/min, a 24-hour urine creatinine clearance can be performed to rule out an underestimation of the eGFR. e) Total serum bilirubin (TBL) ≤ 1.5 x ULN unless the subject has documented Gilbert syndrome in which case up to 3 x ULN is acceptable f) Aspartate and alanine aminotransferase (AST/ALT) ≤ 2.5 x ULN unless liver metastases are present, in which case it must be ≤ 5 x ULN. g) International Normalized Ratio (INR) ≤ 1.5 x ULN unless subject is receiving anticoagulant therapy as long as INR and activated partial thromboplastin time (aPTT) is within therapeutic range of intended use of anticoagulants
Performance status (PS) of 0 or 1 on the ECOG Performance scale
Female subjects of childbearing potential (FSCP) must be willing to use one highly effective method of contraception (detailed at protocol section 6.6.) for the course of the study through 6 months after the last study drug administration. FSCP must have a negative serum pregnancy test done within the 28 days before treatment start. FSCP are those who have not been surgically sterilized or have not been free of menses for at least 1 year.
Absence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial
Absence of any concurrent illness that would preclude the evaluation of safety
Agreement to provide tissue and blood samples for research purposes
Written informed consent must be given according to ICH/GCP, and national/local regulations before patient enrolment
Female
Inclusion criterion applicable to FRANCE only: Affiliated to the French Social Security System. Note: patients eligible for the Synergy trial are also eligible for the AURORA program (NCT02102165) or any other similar molecular screening program, aiming to understand the molecular aberrations in metastatic BC. Patients can be included in both trials in centres recruiting patients for AURORA or for any similar molecular screening program as long as tumour tissue and blood samples can be collected for both studies. If tissue and blood samples cannot be collected for both, it is the investigator choice (and patient) to decide in which trial the patient will enter.
Life expectancy of a least 12 weeks
Body weight above 35kg
The locally recurrent or metastatic relapse must be histologically confirmed TNBC in patients not previously treated with systemic treatment and which cannot be treated with curative intent. Newly diagnosed patients with de-novo metastatic disease are eligible
Estrogen receptor (ER) and progesterone receptor (PR) negativity (<1% positive staining cells in the invasive tumour determined locally using IHC per ASCO/CAP criteria)
Human epidermal growth factor receptor 2 (HER2) negativity (negative IHC staining [score 0 or 1] or negative fluorescence in situ hybridization [FISH] based on the ASCO/CAP guidelines and recommendations from 2013) and determined locally. Note: patients initially diagnosed with hormone receptor–positive and/or HER2-positive breast cancer OR de novo metastatic patients with a primary tumour hormone receptor-positive (weak positivity or ER negativity and PR positivity) considered as non-clinically relevant are eligible if the tumour biopsy obtained from a local recurrence or distant metastasis site confirms the TNBC disease.
Confirmed tumour PD-L1 and CD73 IHC assessment as documented through central testing of a representative tumour tissue specimen for stratification purposes (only for phase II)
Provision of recurrence/metastatic tissue samples from resections, core-needle biopsies or excisional, incisional, punch, or forceps biopsies: - at least 1 FFPE [Formalin-Fixed paraffin-embedded] tumour tissue and 1 frozen core as a priority, if feasible 2 additional fresh tumour tissue cores should be collected too. - Fine-needle aspiration (FNA) (defined as samples that do not preserve tissue architecture and yield cell suspension and/or smears), brushing, and cell pellets from cytology samples are not acceptable. Note 1: If the subject has just performed a metastatic lesion biopsy, she is eligible only if a FFPE tissue sample (or at least 20 unstained slides, freshly cut for the purposes of the study) of the metastatic/recurrent lesion is available. In this situation only, frozen cores are not mandatory. Note 2: In case of a de-novo metastatic disease, if the biopsy of a metastatic lesion is not feasible, the subject is eligible if primary tumour lesion samples (FFPE + frozen core) are available.
Active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease [e.g., colitis or Crohn's disease], diverticulitis [with the exception of diverticulosis], systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome [granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc]). The following are exceptions to this criterion: a) Patients with vitiligo or alopecia b) Patients with hypothyroidism (e.g., following Hashimoto syndrome) stable on hormone replacement c) Any chronic skin condition that does not require systemic therapy d) Patients without active disease in the last 5 years may be included but only after consultation with the sponsor e) Patients with celiac disease controlled by diet alone
Untreated central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases with local treatment (stereotactic radiosurgery or whole brain radiation therapy) may participate provided they have stable brain metastases on a recent brain MRI (performed during the 2 weeks prior inclusion) and have measurable disease outside the CNS. Note: Known brain metastases are considered active (and not eligible for trial), if any of the following criteria are applicable: a) Recent brain imaging demonstrates progression of existing and/or appearance of new lesions b) Neurological symptoms attributed to brain metastases have not returned to baseline c) Steroids were used for management of symptoms related to brain metastases within 14 days of enrolment d) Completion of local therapy for brain metastases within 28 days of enrolment
