|Condition or disease||Intervention/treatment||Phase|
|Multiple Myeloma||Drug: Carfilzomib Drug: Cyclophosphamide Drug: Dexamethasone||Phase 2|
Multiple Myeloma is a cancer that affects the bone marrow where the cells in our blood system are formed. This includes the white cells, red cells, platelets and lymphoid cells. In multiple myeloma the plasma cell (one of the lymphoid cells) starts to reproduce out of control. This results in crowding of the bone marrow with abnormal production of all the cells and a malfunction of the plasma cells. They can also cause damage to the normal bone resulting in pain, fractures and other complications.
The standard or usual treatments for your disease are lenalidomide (an immunomodulatory drug) or bortezomib (a proteasome inhibitor) based treatments.
Carfilzomib is a new type of proteasome inhibitor that is approved for the treatment of relapsed multiple myeloma in the United States.

|Official Title:||A Single Arm Phase II Study of High-Dose Weekly Carfilzomib Plus Cyclophosphamide and Dexamethasone in the Treatment of Relapsed Multiple Myeloma After 1-3 Prior Therapies|
|Actual Study Start Date :||March 29, 2016|
|Actual Primary Completion Date :||June 19, 2019|
|Estimated Study Completion Date :||December 31, 2022|
Experimental: Carfilzomib plus cyclophosphamide plus dexamethasone
20 mg/m2 day 1 of first cycle then escalated to 70 mg/m2 for all subsequent doses) given on days 1, 8, and 15 of a 28 day cycle plus weekly oral dexamethasone (< 70 years, 40 mg; ≥ 70 years 20mg) and cyclophosphamide 300 mg/m2 capped at 500 mg
- Overall Response Rate After 4 Cycles [ Time Frame: 4 months ]
Response rate to protocol treatment after 4 cycles is define by stringent complete response, complete response, partial response, very good partial response, minimal response.
Complete response: Negative immunofixation on the serum and urine and Disappearance of any soft tissue plasmacytomas and < 5% plasma cells in bone marrow biopsy Stringent complete response: Complete response plus Absence of clonal cells in bone marrow d by immunohistochemistry or immunofluorescence Very good partial response: Serum and urine M-protein detectable by immunofixation but not on electrophoresis or ≥90% reduction in serum M-protein with urine M-protein level <100 mg/24 hours.
Partial response: ≥50% reduction in serum M-protein and reduction in 24-hour urinary M-protein by ≥90% or to <200 mg/24 hours Minimal response: 25-49% reduction in serum M-protein, and 50-89% reduction in 24-hour urinary M-protein, if ≥ 200 mg/24 hours at baseline
- Progression-free Survival [ Time Frame: 3 years ]
Median time to progression or death assessed by biochemistry, radiology and immunology tests will be reported. Progression is evaluated in this study using the International Myeloma Working Group Uniform Response Criteria (IMWG-URC) with any one or more of the following:
- Increase of ≥ 25% from lowest response value in: Serum M-component and/or Urine M-component and/or Only in patients without measurable serum and urine M-protein levels; the difference between involved and uninvolved FLC levels or Bone marrow plasma cell percentages.
- Definite development of new bone lesions or soft tissue plasmacytomas or definite increase in the size of existing bone lesions or soft tissue plasmacytomas
- Development of hypercalcemia (corrected serum calcium > 11.5 mg/dL (0.115 g/L) or 2.65 mmol/L) that can be attributed solely to the plasma cell proliferative disorder.
- Overall Survival [ Time Frame: 3 years ]Median time to death in months will be reported
