Weekly 70 mg/m2 Carfilzomib for Multiple Myeloma Patients Refractory to 27 mg/m2 Carfilzomib

Overview

The purpose of this Phase II study is to evaluate the safety and effectiveness (good and bad effects) of carfilzomib given as a 30-minute infusion and at a dose of 70 mg/m2 to treat patients with multiple myeloma (MM), who are currently showing progressive disease (worsening) and had progressed (did not respond to treatment) within 8 weeks of receiving treatment with 27mg/m2 of carfilzomib.

Carfilzomib is approved by the U.S. Food and Drug Administration (FDA) to be used only in certain U.S. patients with relapsed and refractory multiple myeloma that have tried and failed other therapies. Carfilzomib is considered an investigational drug for this study because the dose and regimen included in this study are different from the FDA approved carfilzomib regimen. Carfilzomib is a type of drug called a proteasome inhibitor. Carfilzomib is thought to work by preventing breakdown of abnormal proteins in cells, causing the cells to die. Cancer cells are more sensitive to these effects than normal cells. Carfilzomib has been previously given to more than 1800 people in clinical trials.

Am I Eligible?

The following criteria is a partial list of reasons why patients may or may not be eligible to participate in this clinical trial. Further evaluation with a medical professional will be required to determine full eligibility.

The following criteria is provided for health care professionals.

Inclusion Criteria:

  1. Has a diagnosis of MM based on standard criteria1 as follows:

    Major criteria:

    • Plasmacytomas on tissue biopsy.
    • Bone marrow plasmacytosis (greater than 30% plasma cells).
    • Monoclonal immunoglobulin (Ig) spike on serum electrophoresis IgG greater than 3.5 g/dL or IgA greater than 2.0 g/dL; kappa or lambda light chain excretion greater than 1 g/day on 24-hour urine protein electrophoresis.

    Minor criteria:

    • bone marrow plasmacytosis (10% to 30% plasma cells)
    • monoclonal immunoglobulin present but of lesser magnitude than given under major criteria
    • lytic bone lesions
    • normal IgM less than 50 mg/dL, IgA less than 100 mg/dL, or IgG less than 600 mg/dL

    Any of the following sets of criteria will confirm the diagnosis of multiple myeloma:

    • any 2 of the major criteria
    • major criterion 1 plus minor criterion 2, 3, or 4
    • major criterion 3 plus minor criterion 1 or 3
    • minor criteria 1, 2, and 3, or 1, 2, and 4
  2. Currently has progressive MM that has progressed while receiving or within 8 weeks of receiving carfilzomib 27mg/m2 alone or as part of their last carfilzomib-containing combination regimens.
  3. Patient must have received at least one full cycle of carfilzomib at a dose of 27mg/m2 prior to showing evidence of PD from their last carfilzomib-containing regimen.
  4. Patient must have previously received treatment with an immunomodulatory agent to be eligible for the study.
  5. There is no limit to the number of prior lines of therapy that a patient may have received.
  6. Measurable disease, as defined by one or more of the following (assessed within 14 days prior to first dose):
    • Serum M-protein ≥ 0.5 g/dL, or
    • Urine M-protein ≥ 200 mg/24 hours, or
    • Only in patients who do not meet a or b, then use serum free light chain (SFLC) > 100 mg/L (involved light chain) and an abnormal κ/λ ratio
  7. Age ≥ 18 years.
  8. Life expectancy ≥ 6 months.
  9. Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2.
  10. Adequate hepatic function within 14 days prior to first dose, with bilirubin < 1.5 × the upper limit of normal (ULN), and aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < 3 × ULN.
  11. LVEF ≥ 40%. 2-D transthoracic echocardiogram (ECHO) is the preferred method of evaluation. Multigated Acquisition Scan (MUGA) is acceptable if ECHO is not available.
  12. Absolute neutrophil count (ANC) ≥ 1000/mm3 within 14 days prior to first dose. Screening ANC is to be independent of granulocyte colony stimulating factor support for ≥ 1 week and pegylated granulocyte colony stimulating factor for ≥ 2 weeks.
  13. Hemoglobin ≥ 8.0 g/dL within 14 days prior to enrollment. Use of erythropoietic stimulating factors and red blood cell (RBC) transfusions per institutional guidelines is allowed; however, most recent RBC transfusion must have been at least 7 days prior to obtaining screening hemoglobin.
  14. Platelet count ≥ 75,000/mm3 (≥ 50,000/mm3 if myeloma involvement in the bone marrow is > 50%) within 14 days prior to first dose. Patients must not have received platelet transfusions for at least 7 days prior to obtaining the screening platelet count.
  15. Calculated or measured creatinine clearance (CrCl) of ≥ 30 mL/min within 14 days prior to first dose. Calculations are based on a standard formula, such as the Cockcroft and Gault: [(140 - Age) × Mass (kg) / (72 × Creatinine mg/ dL)]; multiply result by 0.85 if female.
  16. Written informed consent in accordance with federal, local, and institutional guidelines.
  17. Women of childbearing potential (WOCBP) must have a negative serum pregnancy test within the 7 days prior to study drug administration and a negative urine pregnancy test within the 3 days prior to the first study drug administration
  18. WOCBP and male subjects who are sexually active with WOCBP must agree to use 2 highly effective methods of contraception during the study and for 30 days following the last dose of study treatment including a male condom.
