2. POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes)

3. Plasma cell leukemia

4. Chemotherapy with approved or investigative anticancer therapeutics, including steroid therapy dose as defined above, within 14 days prior to first dose of study drug or antibody therapy within 6 weeks prior to first dose of study drug

5. Radiation therapy or immunotherapy within 3 weeks prior to first dose; localized radiation therapy within 1 week prior to first dose

7. Prior carfilzomib treatment

8. Pregnant or lactating females

9. Major surgery within 3 weeks prior to first dose of study drug

10. Congestive heart failure (New York Heart Association Class III to IV), symptomatic ischemia, conduction abnormalities or myocardial infarction in the three months prior to first dose of study drug

11. Uncontrolled hypertension

15. Other malignancy within the past 3 years except a) adequately treated basal cell or squamous cell skin cancer, b) carcinoma in situ of the cervix, or c) prostate cancer < Gleason Grade 7 with stable prostate specific antigen (PSA) levels

16. Any clinically significant medical or psychiatric disease or condition that, in the Investigator's opinion, may interfere with protocol adherence or a subject's ability to give informed consent

17. Significant neuropathy (Grade 3, Grade 4, or Grade 2 with pain) at the time of the first dose and/or within 14 days prior to enrollment

18. Subjects in whom the required program of oral hydration and intravenous fluid hydration is contraindicated, e.g., due to preexisting pulmonary or cardiac impairment

19. Subjects with pleural effusions requiring routine thoracentesis or ascites requiring routine paracentesis

20. Subjects with a known contraindication to receiving dexamethasone or allopurinol

21. Receipt of granulocyte- and granulocyte/ macrophage- colony stimulating factor (G-CSF and GM-CSF) within 1 week prior to first dose of study drug
