简要总结
This randomized phase III trial compares bortezomib, dexamethasone, and lenalidomide with bortezomib and dexamethasone to see how well they work in treating patients with multiple myeloma previously treated with dexamethasone. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Lenalidomide may stimulate the immune system in different ways and stop cancer cells from growing. It is not yet known whether giving bortezomib and dexamethasone is more effective with or without lenalidomide in treating multiple myeloma.
详细描述
PRIMARY OBJECTIVES:
I. To compare the progression-free survival (PFS) for two consolidation regimens: bortezomib, lenalidomide, and dexamethasone (VRD) versus bortezomib and dexamethasone (VD) only.
SECONDARY OBJECTIVES:
I. To determine the incremental ability of VRD versus VD in attaining a complete response or a very good partial response (VGPR) in patients receiving induction therapy with a dexamethasone based induction regimen.
II. To compare the overall survival, measured from the time of study entry.

研究组 & 干预措施
Arm A (VRD)
Patients were given consolidation therapy for 8 cycles (1 cycle = 21 days) with the combination bortezomib, dexamethasone and lenalidomide. Patients received each cycle: the standard dose of bortezomib (1.3 mg/m2) on days 1, 4, 8 and 11; fixed dose of lenalidomide at 15 mg orally on days 1-14; and 3 days of dexamethasone at 40 mg total dose per day given on days 1, 8 and 15. Aspirin 325 mg/day orally on days 1-21 of each cycle was required unless the patient was treated with alternate prophylaxis of either low molecular weight heparin or coumadin.

结局指标
主要结局
Progression-free Survival (PFS)
时间窗: Assessed every 3 months if patient is < 2 years from study entry, every 6 months if patient is 2-5 years from study entry, every 12 months if patient is 6-10 years from study entry, up to 10 years
Progression-free survival was defined as the time from randomization to the earliest documentation of disease progression (PD) or death. If a patient died without evidence of PD, the patient was considered an event if death occurred within 3 months of the last disease assessment. Patients who died outside of the specified interval or patients who were alive without evidence of PD were censored at the date of last disease assessment. The PFS results are based on data as of August 2012, while overall survival (OS) was updated in April 2014. Given the early termination and limited sample size, data management efforts to update PFS were not pursued.
