Written informed consent prior to beginning specific protocol procedures, including expected cooperation of the patients for the treatment and followup, and documented according to the local regulatory requirements., The patient must be accessible for scheduled visits, treatment, and follow-up., Normal cardiac function must be confirmed according to local guidelines., Laboratory requirements: Hematology • Absolute neutrophil count (ANC) =1.5 x 109 / L • Platelets =100 x 109 / L • Hemoglobin =10 g/dL (=6.2 mmol/L) Hepatic function • Total bilirubin <1.25x ULN • AST and ALT <=1.5x ULN • Alkaline phosphatase <=2.5x ULN Glucose Metabolism • HbA1c <8.0% (63.9 mmol/mol) Renal Function • Creatinine <1.25x ULN or creatinine clearance =50 ml/min (if creatinine is above ULN according to Cockroft-Gault), Complete staging work-up prior to the initiation of neoadjuvant therapy as per standard recommendations., Postmenopausal women with age at diagnosis = 18 years. Postmenopausal status is defined as: • Age = 60 years • Age <60 years and amenorrhea for at least 12 continuous months with no identified cause other than menopause • Bilateral oophorectomy Negative pregnancy test (urine or serum) within 14 days prior to randomization for all postmenopausal women 50 years of age or younger without bilateral oophorectomy, Unilateral or bilateral primary untreated lobular invasive carcinoma of the breast. In case of bilateral breast cancer, both sides must be lobular; the lead tumor has to be defined by the investigator based on the inclusion criteria for the respective subtype and the risk status. Lobular histology has to be centrally confirmed., Willingness and ability to provide archived formalin fixed paraffin embedded (FFPE) tissue block from core biopsy before the start of neoadjuvant therapy., Centrally confirmed HER2-negative (IHC score 0-1+ or ISH negative according to ASCO/CAP guideline) and HR-positive (=10% positive stained cells) disease, assessed on the core of diagnostic biopsy. Ki67% >10% is required. In case of bilateral breast cancer, HER2-negative, HR-positive and lobular histology status has to be confirmed for both sides., Patients with invasive lobular breast cancer at high risk for recurrence defined as cT1c and clinical nodal involvement (cN+) or = cT2 disease (irrespective of nodal involvement)., No clinical evidence of distant metastases., Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1., Estimated life expectancy of at least 5 years irrespective of the diagnosis of breast cancer.
Female patients of childbearing potential., Patients with definitive clinical or radiologic evidence of stage IV cancer (metastatic disease) are not eligible., Patients with a history of any malignancy are ineligible with the following exceptions: • Patient has been disease-free for at least 5 years and is at low risk for recurrence of that malignancy except for breast cancer. • CIS of the cervix, basal cell and squamous cell carcinomas of the skin., History of type I or type II diabetes mellitus requiring insulin., Severe and relevant co-morbidity that would interact with the application of study drugs or the participation in the study, including cerebrovascular incident including transient ischemic attack, or symptomatic pulmonary embolism, active infection requiring intravenous anti -microbial treatment (antibiotics, anti-fungal, and anti-viral drugs) within 1 week of enrolment. Patients with confirmed Gilbert’s syndrome may be included in the study., Known medically history of HIV infection, tuberculosis, or hepatitis B., History of and/or active cardiac disease that would preclude the use of study treatments. This includes but is not confined to any of the following cardiac criteria: • Clinically significant cardiac dysfunction including heart failure (NYHA II-IV), active ventricular arrhythmias requiring medication or arrhythmias requiring a pacemaker, and history of a myocardial infarction within 6 months prior to randomization, angina pectoris, atrial fibrillation of any grade, coronary/peripheral artery bypass graft, angioplasty, or vascular stent. • Mean resting QT interval corrected by Fridericia’s formula (QTcF) >470 msec obtained from 3 consecutive ECGs. • Increased risk of QTc prolongation or risk of arrhythmic events such as heart failure, uncontrolled electrolyte disorders (e.g., hypocalcemia, hypokalemia, or hypomagnesemia), potential for torsades de pointes, congenital long QT syndrome, family history of long QT syndrome or unexplained sudden death under 40 years of age, or any concomitant medication known to prolong the QT interval., Receipt of live attenuated vaccination within 30 days prior to study entry or within 30 days of receiving therapy., History of significant neurological or psychiatric disorders including psychotic disorders, dementia, or seizures that would prohibit the understanding and giving of informed consent., Any condition that, in the opinion of the investigator, would interfere with evaluation of study treatment or interpretation of patient safety or study results (such as severe or uncontrolled systemic diseases, including uncontrolled hypertension or hypotension (BP <50mmHg), significant aneurysm, renal transplant and active bleeding diseases)., Major surgical procedure (excluding placement of vascular access) or significant traumatic injury within 4 weeks of the first dose of study intervention or an anticipated need for major surgery during the study., Excisional biopsy or lumpectomy performed prior to study entry., Participation in another clinical study with a study intervention or investigational medicinal device administered in the 4 weeks prior to first dose of study intervention or concurrent enrolment in another clinical study unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study., Surgical axillary staging procedure including sentinel lymph node biopsy prior to randomization. Exceptions: FNA or core biopsy of an axi
