Safety Study of the Proteasome Inhibitor PR-171 (Carfilzomib for Injection) in Patients With Hematological Malignancies
A Phase I Study of the Safety and Pharmacokinetics of Escalating Intravenous Doses of the Proteasome Inhibitor PR-171 in Patients With Hematological Malignancies
The purpose of this study is to test the safety and tolerability of carfilzomib at different dose levels on hematological cancers such as multiple myeloma, non-Hodgkin's lymphoma, Hodgkin's disease, or Waldenstrom's macroglobulinemia. Carfilzomib is a proteasome inhibitor, an enzyme responsible for degrading a wide variety of cellular proteins.

Total white blood cell (WBC) count ≥ 2,000/mm³, absolute neutrophil count (ANC) ≥ 1000/mm³, hemoglobin ≥ 8.0 g/dL, and platelet count ≥ 50,000/mm³ - Screening ANC should be independent of granulocyte colony stimulating factor (G-CSF) or granulocyte-macrophage colony-stimulating factor (GM-CSF) support for ≥ 1 week and of pegylated G-CSF for ≥ 2 weeks) - Subjects receiving supportive care including erythropoietin, darbepoetin and/or bisphosphonates can continue to do so, but must be transfusion independent; subjects receiving erythropoietic support must remain on the same dose for the first 28 days of study participation 9. An estimated creatinine clearance of ≥ 30 mL/min, calculated using the formula of Cockroft and Gault 10. Serum creatinine ≤ 2.0 mg/dL 11. Uric acid, if elevated, must be corrected to within laboratory normal range prior to dosing 12. Female subjects of child-bearing potential must agree to use dual methods of contraception and have a negative serum pregnancy test. Male subjects must use an effective barrier method of contraception throughout the study and for three months following the last dose if sexually active with a female of child-bearing potential. Exclusion Criteria: 1. Female subjects who are pregnant or lactating 2. Subjects who are transfusion dependent 3. Subjects with NHL or HL who have received steroid therapy in the previous seven days 4. Subjects with MM or Waldenström's Macroglobulinemia who have received steroid therapy in the previous three weeks, except for MM subjects in the Carfilzomib + DEX Expansion Cohort, where previous treatment with dexamethasone will be allowed. The dose and schedule of administration of dexamethasone will be adjusted to that used in the protocol 5. Radiation, chemotherapy, or immunotherapy in the previous four weeks, or subjects who, in the judgment of the Investigator, have not recovered from the effects of previous therapy 6. For the Dose Escalation period, subjects who have received prior radioimmunotherapy with anti-cluster of differentiation (CD)20 monoclonal antibodies such as Bexxar® or Zevalin®; subjects treated with these products will be allowed in the Dose Expansion period 7. Subjects who have received allogeneic stem cell transplant therapy 8. Subjects with NHL or HL who have received autologous stem cell transplant therapy and have relapsed within 100 days of therapy 9. Rituxan therapy within three months before Day 1 unless there is evidence of disease progression 10. Major surgery within three weeks before Day 1 11. Congestive heart failure (CHF) (New York Heart Association class III to IV) 12.
