    Note: Ovarian radiation or treatment with a luteinizing hormone-releasing hormone agonist (goserelin acetate or leuprolide acetate) is not permitted for induction of ovarian suppression.

  4. Patients who have a history of brain metastasis are eligible for the study provided that all the following criteria are met:

    • Brain metastases which have been treated
    • No evidence of disease progression for ≥ 3 months or hemorrhage after treatment
    • Off-treatment with dexamethasone for 4 weeks before administration of the first dose of MLN0128
    • No ongoing requirement for dexamethasone or anti-epileptic drugs
  5. Eastern Cooperative Oncology Group (ECOG) performance status 0 to 2.
  6. Clinical laboratory values as specified below within 4 weeks before the first dose of MLN0128:

    • Total bilirubin ≤ 1.5 x the upper limit of the normal range (ULN), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 2.5 x ULN (≤ 5 x ULN if liver metastases are present)
    • Creatinine clearance ≥ 50 mL/min based either on Cockcroft-Gault estimate or based on a 12- or 24-hour urine collection

  7. Left ventricular ejection fraction (LVEF) within 5 absolute percentage points of institutional standard of normal as measured by echocardiogram (ECHO) or multiple gated acquisition scan (MUGA) within 4 weeks before the first dose of MLN0128 (ie, if the institutional standard of normal is 50%, LVEF may be as low as 45% to be eligible for the study).
  8. Able to provide paraffin blocks or a minimum of 10 unstained slides of available archival tumor tissues (paraffin blocks are preferred). If archival tumor tissue is not available, a tumor biopsy may be performed before the patient begins treatment with MLN0128.
