Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Carfilzomib

Arm Description

Carfilzomib 20 mg/m2 on day 1, 2 then 56 mg/m2 days 8, 9 and 15, 16 over 30 minutes every 28 days. Dexamethasone 4 mg (8 mg if > 45 mg/m2) orally each day of carfilzomib therapy. If less than a partial remission (PR) after 4 cycles, add rituximab 375 mg/m2 on day 16 of each cycle. Patients who meet the criteria for progression prior to 4 cycles of therapy will have rituximab added to their treatment. For patients receiving rituximab, the carfilzomib dose will be decreased to 27 mg/m2. Patients will be treated to maximal response plus 2 additional cycles to a maximum of 12 cycles.

Outcomes

Primary Outcome Measures

Overall Response Rate (ORR) of Carfilzomib in Bortezomib naïve and Bortezomib-exposed Relapsed WM

The overall response rate (ORR) (rate of patients attaining a Partial Response or a Complete Response). Responses will be based on both serum paraprotein levels by SPEP and bidimensional disease measurements on CT scan for patients with adenopathy/organomegaly/lymphadenopathy. Criteria as per the Recommended Response Criteria for Waldenstrom Macroglobulinemia Complete Response: Absence of serum monoclonal IgM protein by immunofixation Normal serum IgM level Complete resolution of extramedullary disease, i.e., lymphadenopathy and splenomegaly if present at baseline Morphologically normal bone marrow aspirate and trephine biopsy Partial response (PR) Monoclonal IgM protein is detectable -≥50% but<90% reduction in serum IgM level from baseline Reduction in extramedullary disease, i.e., lymphadenopathy/splenomegaly if present at baseline No new signs or symptoms of active disease

5. Study Description

Brief Summary

The purpose of this study is to evaluate the safety and effectiveness of an investigational study drug called carfilzomib. The investigators want to find out what effects, good and/or bad, it has on patients and their cancer if treatment continues beyond previous carfilzomib treatment study. Carfilzomib (KyprolisTM) 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. It has not been approved to be used for any other disease or condition. In this study, carfilzomib is referred to as an investigational study drug because it is not approved for use in all patients with multiple myeloma in the United States, and it is not approved by some regulatory authorities (the agencies that are responsible for approving the use of a medicine in a country such as Health Canada). Carfilzomib is a type of drug called a proteasome inhibitor. A proteasome is a protein found within cells that has the important role of identifying and marking damaged proteins that are needed to be destroyed by the cell for survival. The inhibition of the proteasome allows for damaged protein to accumulate within cells. This accumulation of damaged protein causes the cell to die.

Detailed Description

Waldenström's macroglobulinemia (WM) is a rare low-grade B-cell lymphoplasmacytic lymphoma. Overall reported incidences approximately 3 cases per million persons per year with about 1500 and cases diagnosed annually in United States. There is a higher incidence in males compared to females (3.4 vs 1.7 cases per 1 million person-years at risk) and WM is nearly twice as common among whites compared to blacks.[1] A familial form of the disease is also recognized. WM is an indolent disease with an overall median survival of 5 years although more recent data suggest a disease-specific median survival of 11.2 years, given the frequently older age (median 63 years) and accompanying co-morbidities at diagnosis(1). WM is characterized by infiltration of lymphoplasmacytic cells and bone marrow and by serum immunoglobulin M (IgM) monoclonal gammopathy. B-cell origin and some clinical cellular and epidemiological features are shared among WM arises from intermediately mature B cells (somatically mutated post germinal center the lymphocytes that have not yet undergone isotype switching), as opposed to immature B cells from which chronic lymphocytic leukemia arises in the fully mature, somatically mutated, from which cells multiple myeloma arises. There is no standard of care for WM (2). Therefore, involving the patient's in clinical trials is strongly recommended whenever possible.
