   - Patients are unwilling, or who are determined to be medically unfit for or resistant
   to standard intensive induction chemotherapy; patients who are medically unfit will be

   - Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 3 x ULN

   - Calculated creatinine clearance ≥ 30 mL/min

Exclusion Criteria:

   - Female patient who are lactating or have a positive serum pregnancy test during the
   screening period

   - Major surgery within 14 days before enrollment

   - Radiotherapy within 14 days before enrollment; if the involved field is small, 7 days
   will be considered a sufficient interval between treatment and administration of

   - Have other severe concurrent disease or serious organ dysfunction involving the heart,
   kidney, liver or other organ system that may place the patient at undue risk to

   arrhythmias, symptomatic congestive heart failure, unstable angina, or myocardial
   infarction within the past 6 months

   - Systemic treatment, within 14 days before the first dose of MLN9708, with strong
   inhibitors of cytochrome P450, family 1, subfamily A, polypeptide 2 (CYP1A2)
   (fluvoxamine, enoxacin, ciprofloxacin), strong inhibitors of cytochrome P450, family
   3, subfamily A (CYP3A) (clarithromycin, telithromycin, itraconazole, voriconazole,
   ketoconazole, nefazodone, posaconazole) or strong CYP3A inducers (rifampin,

   disease; patients with nonmelanoma skin cancer or carcinoma in situ of any type are
   not excluded if they have undergone complete resection; this does not preclude
   previous diagnosis of acute myeloid leukemia or myelodysplastic syndrome

   - Patient has ≥ grade 3 peripheral neuropathy, or grade 2 with pain on clinical
