- Adequate hepatic function, with bilirubin ≤ 1.5 times the upper limit of normal (ULN) in the absence of Gilbert's disease or hemolysis, and alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 3 times ULN.
- Absolute neutrophil count (ANC) ≥ 1000/mm3. Screening ANC must be independent of myeloid growth factor support for at least 1 week, or pegylated growth factors for 2 weeks.
- Hemoglobin > 7g/dL. Patients may receive red blood cell (RBC) transfusions or erythropoietin or darbepoetin in accordance with institutional guidelines up to 1 week before screening.
- Platelet count > 30,000 mm3. Patients will not have received platelet transfusions for at least 1 week before screening.
- Uric acid, if elevated, must be lowered to less than the ULN.
- Calculated or measured creatinine clearance (CrCl) ≥ 30 mL/min calculated using the formula of Cockcroft and Gault [(140 - age) × mass (kg) / (72 × serum creatinine mg/dL)]. Multiply result by 0.85 if female.
Key
- Recovered (i.e., ≤ Grade 1 toxicity or patient's baseline status) from the reversible nonhematologic effects of prior anticancer therapy, excluding alopecia.
- Systemic chemotherapy with approved or investigational anticancer therapeutics, including steroid therapy intended to treat underlying malignancy, within 3 weeks before the first oprozomib dose; for antibody therapy, a minimum of 3 half-lives must elapse before the first oprozomib dose.
- Radiation therapy within 3 weeks before first oprozomib dose. Radioimmunotherapy within 8 weeks before first oprozomib dose.
- Autologous stem cell transplant (ASCT) within 8 weeks and allogeneic SCT within 16 weeks prior to initiation of study treatment. Patients with prior allogeneic SCT must not have evidence of moderate-to-severe graft-versus-host disease (as defined in Filipovich 2005).
- Unresolved toxicity (NCI-CTCAE version 4.03) ≥ Grade 2 from previous anticancer therapy, except alopecia.
- Major surgery within 3 weeks before first oprozomib dose.
- Congestive heart failure (New York Heart Association Class III to IV)
- Symptomatic cardiac ischemia.
- Conduction abnormalities uncontrolled by conventional intervention, including but not limited to persistent or permanent atrial fibrillation.
- History of ventricular fibrillation or ventricular tachycardia.
- History of torsade de pointe.
- Myocardial infarction within 6 months before first dose.
- Abnormal measurements on 12-lead ECG.
- Uncontrolled diabetes mellitus or hypertension
- Dysphagia or inability to swallow tablets.
- Insufficiency of the exocrine pancreas, steatorrhea, or other disorders of the digestive system that impair absorption.
- Resection of any portion of the stomach or intestines, with the exception of appendectomy.
- History of bariatric surgery, except in cases where no bowel was resected and all devices have been removed.
- Active infection requiring systemic antibiotics, antivirals, or antifungals within 2 weeks before first dose, unless cultures or polymerase chain reaction (PCR) have been negative for 14 days.
- Known human immunodeficiency virus (HIV) positive, hepatitis B surface antigen-positive, or suspected hepatitis C infection.
- Primary malignancy of the central nervous system.
- Patient has symptomatic brain metastasis. Patients with brain metastases must have stable neurologic status following surgery or radiation for at least 2 weeks after completion of the definitive therapy, AND be without neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.
- Significant peripheral neuropathy (Grade 2 with pain or ≥ Grade 3).
- Systemic treatment with strong inhibitors of P-glycoprotein ([P-gp]; i.e., itraconazole, ketoconazole) within 14 days before the first dose of oprozomib.
- Patients must not have used any potent CYP3A4 inhibitors (i.e., ketoconazole) within 7 days prior to enrollment, or any potent CYP3A4 inducers (i.e., rifampin) within 14 days prior to enrollment.

- Arm && Interventions
- Group - Intervention - Description - Part II: Drug-Drug Interaction (DDI) - Midazolam - * Period 1: Midazolam 2 mg single oral dose on one day between Day -7 and -4 * Period 2: Midazolam 2 mg single oral dose 1 hour following oprozomib dose on Day 1 of Cycle 1 and Day 2 of Cycle 2. Oprozomib 300 mg dose on Days 1, 2, 8 and 9 of Cycles 1 and Cycle 2 - Part I: Food Effect/QTc - Oprozomib - Subjects will receive a single dose of oprozomib 270 mg in 1 of 3 fasting/fed conditions: * Diet A: Fasted conditions * Diet B: A low-fat breakfast. A low-fat breakfast is defined as having a total caloric value of less than 400 calories, with less than 20% from fat * Diet C: A high-fat breakfast. A high-fat breakfast is defined as having a total caloric value of 800 to 1000 calories, with approximately 50% from fat - Part II: Drug-Drug Interaction (DDI) - Oprozomib - * Period 1: Midazolam 2 mg single oral dose on one day between Day -7 and -4 * Period 2: Midazolam 2 mg single oral dose 1 hour following oprozomib dose on Day 1 of Cycle 1 and Day 2 of Cycle 2. Oprozomib 300 mg dose on Days 1, 2, 8 and 9 of Cycles 1 and Cycle 2 - Extension - Oprozomib - After subjects complete the Food Effect/QTc or DDI part, subjects may participate in the extension part of the study, where oprozomib treatment will be continued on Days 1, 2, 8, and 9 of each 14-day cycle. During this part of the study, it is recommended that oprozomib be taken with food.

 * Twelve (12)-lead ECGs will be serially recorded digitally and read centrally
 * The RR, PR and QT intervals and QRS duration will be analyzed
 * QTc will be calculated using Bazett's and Fridericia's formulas- Drug-Drug Interaction (DDI) - Cmax - Approximately 1 month - Pharmacokinetics (PK) parameter Cmax (maximum plasma concentration) of midazolam, in the presence and absence of oprozomib. - Drug-Drug Interaction (DDI) - AUC - Approximately 1 month - Pharmacokinetics (PK) parameter AUC (area under the concentration-time curve from time zero to the last measurable time point \[AUC0-t\], area under the concentration-time curve from time zero to infinity \[AUC0-inf\]) of midazolam, in the presence and absence of oprozomib.
