Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Female or male ≥ 18 years of age.
• Newly diagnosed ER-positive, HER2-negative breast cancer. ER-positive is defined as ≥ 1% immunohistochemical (IHC) staining of any intensity. HER2 test result is negative if a single test (or both tests) performed show:
• IHC 1+ or 0
• In situ hybridization negative based on:
• Single-probe average HER2 copy number < 4.0 signals/cell
• Dual-probe HER2/CEP17 ratio < 2 with an average HER2 copy number < 4.0 signals/cell.
• Patients with stage II-III breast cancer are eligible if they are deemed appropriate for neoadjuvant endocrine therapy by the referring or treating medical oncologist. Patients with stage I disease are eligible if they are deemed borderline candidates for breast conservation and the treating surgeon recommends preoperative therapy to increase the chances of breast conservation.
• Eastern Cooperative Oncology Group performance status and/or other performance status of ≤ 1.
• Female patients who:
• Are postmenopausal for at least 1 year before the screening visit, OR
• Are surgically sterile, OR
• If they are of childbearing potential, agree to practice 1 effective method of contraception and 1 additional effective (barrier) method, at the same time, from the time of signing the ICF through 90 days (or longer, as mandated by local labeling [e.g., United Surgical Partners International, summary of product characteristics, etc.] after the last dose of the study drugs, OR
• Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the patient (periodic abstinence [e.g., calendar, ovulation, symptothermal, postovulation methods] and withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception. Female and male condom should not be used together).
• Male patients, even if surgically sterilized (i.e., status post-vasectomy), who:
• Agree to practice highly effective barrier contraception during the entire study treatment period and through 120 days after the last dose of the study drugs, OR
• Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the patient
• Agree not to donate sperm during the course of this study or within 120 days after receiving their last dose of the study drugs.
• Screening clinical laboratory values as specified below:
• Bone marrow reserve consistent with: absolute neutrophil count ≥ 1.5 x 109/L, platelet count ≥ 100 x 109/L, and hemoglobin ≥ 9 g/dL (without transfusion) within 1 week preceding the administration of the study drugs;
• Hepatic status: Serum total bilirubin ≤ 1 x upper limit of normal (ULN; in the case of known Gilbert's syndrome, a higher serum total bilirubin [< 1.5 x ULN] is allowed), aspartate aminotransferase and alanine aminotransferase ≤ 1.5 x ULN, and alkaline phosphatase ≤ 1.5 x ULN;
• Renal status: Creatinine clearance ≥50 mL/min based on Cockcroft-Gault estimate or based on urine collection (12 or 24 hour);
• Metabolic status: HbA1c < 7.0%, fasting serum glucose ≤ 130 mg/dL, and fasting triglycerides ≤ 300 mg/dL.
• Ability to swallow oral medications.
• Voluntary written consent must be given before performance of any study-related procedure not part of standard medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to future medical care.
• Negative serum pregnancy test within 7 days prior to the administration of the study drugs for female patients of childbearing potential.

You may not qualify if…

• Any patient with metastatic disease.
• Other clinically significant comorbidities, such as uncontrolled pulmonary disease, active central nervous system disease, active infection, or any other condition that could compromise the patient's participation in the study.
• Known human immunodeficiency virus infection.
• Known hepatitis B surface antigen-positive or known or suspected active hepatitis C infection.
• Any serious medical or psychiatric illness that could, in the investigator's opinion, potentially interfere with the completion of the protocol-specified treatment.
• Diagnosed or treated for another malignancy within 2 years before administration of the first dose of the study drugs or previously diagnosed with another malignancy and have any evidence of residual disease. Patients with non-melanoma skin cancer or carcinoma in situ of any type are not excluded if they have undergone complete resection.
• Breastfeeding or pregnant.
• Manifestations of malabsorption due to prior gastrointestinal surgery, gastrointestinal disease, or an unknown reason that may alter the absorption of TAK-228. Patients with enteric stomata are also excluded.
• Treatment with any investigational products within 2 weeks before administration of the first dose of the study drugs.
• Poorly controlled diabetes mellitus (defined as HbA1c > 7%). Patients with a history of transient glucose intolerance due to corticosteroid administration may be enrolled in the study if all other inclusion criteria and none of the other exclusion criteria are met.
• History of any of the following within the last 6 months before administration of the first dose of the study drugs:
• Ischemic myocardial event, including angina requiring therapy and artery revascularization procedures
• Ischemic cerebrovascular event, including transient ischemic attack and artery revascularization procedures
• Requirement for inotropic support (excluding digoxin) or serious (uncontrolled) cardiac arrhythmia (including atrial flutter/fibrillation, ventricular fibrillation, and ventricular tachycardia)
• Placement of a pacemaker for control of rhythm
• New York Heart Association Class III or IV heart failure
• Pulmonary embolism
• Significant active cardiovascular or pulmonary disease including:
• Uncontrolled hypertension (i.e., systolic blood pressure > 180 mm Hg, diastolic blood pressure > 95 mm Hg). Use of antihypertensive agents to control hypertension before week 1, day 1 is allowed.
• Pulmonary hypertension
• Uncontrolled asthma or O2 saturation < 90% by arterial blood gas analysis or pulse oximetry on room air
• Significant valvular disease, severe regurgitation, or stenosis by imaging independent of symptom control with medical intervention or history of valve replacement
• Medically significant (symptomatic) bradycardia
• History of arrhythmia requiring an implantable cardiac defibrillator
• Baseline QTc prolongation (e.g., repeated demonstration of QTc interval > 480 milliseconds or history of congenital long QT syndrome or torsades de pointes)
