A Phase II Study of Carfilzomib in Relapsed Waldenström's Macroglobulinemia (WM) IST-CAR-531
In Brief
A Phase 2 clinical trial evaluating Carfilzomib, Rituximab, and 1 other intervention for Waldenstrom Macroglobulinemia. Completed, enrolled 7 participants across 1 site.
Detailed 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.

Timeline
Interventions
If you decide to participate in the study, you will receive carfilzomib on Days 1, 2, 8, 9, 15, and 16 every 28 days for a minimum of 2 cycles (approximately 2 months). You may receive additional cycles for as long as your disease remains stable or improved or until your study doctor determines that you should stop receiving the study drug or you decide to stop participating in the study.
If you decide to participate in the study, in addition to the carfilzomib and possible dexamethasone administration, If less than a partial remission (PR) after 4 cycles is achieved, rituximab 375 mg/m2 on day 16 of each subsequent cycle will be added to the treatment. Subjects who meet the criteria for progression prior to 4 cycles of therapy will have rituximab 375 mg/m2 weekly for 4 consecutive weeks every 3 cycles added to the treatment. Subjects will be treated to maximal response plus 2 additional cycles to a maximum of 12 cycles. At the beginning of every cycle, your study doctor will see if your general health is satisfactory. You will be asked to report any side effects or problems you have had since the start of the last treatment cycle as well as any medication change(s).
