Life expectancy \> 3 months 5. Eastern Cooperative Oncology Group (ECOG) performance status 0-2 6. Adequate hepatic function, with bilirubin \< 1.5 x the ULN, and AST (Aspartate Aminotransferase) and ALT (Alanine Transaminase) \< 2.5 x ULN 7.

Written informed consent in accordance with federal, local, and institutional guidelines. 10. Subjects must agree to adhere to all study requirements, including birth control measures and pregnancy testing, visit schedule, outpatient treatment, required concomitant medications, and laboratory monitoring. 11. Must be able to take either 81 mg or 325 mg aspirin daily as prophylactic anticoagulation. Exclusion Criteria 1. Non-secretory or hyposecretory multiple myeloma, defined as \<0.5 g/dL M-protein in serum, \<200 mg/24 hr urine M-protein, or disease only measured by serum free light chain 2.

Radiotherapy to multiple sites or immunotherapy within 2 weeks before start of protocol treatment (localized radiotherapy to a single site at least 1 week before start is permissible) 6. Patient must not have been previously treated with any prior systemic therapy for the treatment of multiple myeloma * Prior treatment of hypercalcemia or spinal cord compression or aggressively progressing myeloma with corticosteroids does not disqualify the patient (the dose should not exceed the equivalent of 160 mg of dexamethasone in a 2 week period) * Bisphosphonates are permitted 7. Participation in an investigational therapeutic study within 3 weeks or within 5 drug halflives (t1/2) prior to first dose, whichever time is greater 8. Pregnant or lactating females 9. History of allergy to mannitol 10. Major surgery within 3 weeks prior to first dose 11.
