This randomized phase III trial is studying bortezomib, dexamethasone, and lenalidomide to see how well they work compared with bortezomib and dexamethasone 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 together with dexamethasone is more effective with or without lenalidomide in treating multiple myeloma
Further Study Information
I. To compare the progression-free survival (PFS) of patients with previously treated symptomatic multiple myeloma treated with consolidation therapy comprising bortezomib and dexamethasone with vs without lenalidomide.
I. To determine the incremental ability of these regimens in attaining a complete response or a very good partial response (VGPR) in these patients.
II. To compare the overall survival of patients treated with these regimens. III. To compare the toxicity of these regimens in these patients. IV. To compare the quality of life of these patients. V. To examine the impact of differential treatment response, if observed, on quality of life of these patients.
VI. To obtain prospective data on multiple myeloma specific quality of life attributes.
OUTLINE: Patients are stratified according to prior induction therapy with lenalidomide and dexamethasone (yes vs no) and whether or not they are in complete response after induction therapy at study registration (yes vs no). Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive bortezomib IV on days 1, 4, 8, and 11, oral lenalidomide once a day on days 1-14, and oral dexamethasone once a day on days 1-4. Treatment repeats every 21 days for 8 courses in the absence of disease progression or unacceptable toxicity.
ARM II: Patients receive bortezomib IV on days 1, 4, 8, and 11 and oral dexamethasone once a day on days 1-4. Treatment repeats every 21 days for 8 courses in the absence of disease progression or unacceptable toxicity.
Quality of life is assessed periodically. After completion of study treatment, patients are followed every 3 months for 2 years, every 6 months for 3 years, and then every 12 months for 5 years.
- Diagnosis of symptomatic multiple myeloma
- Must meet the following criteria at one point in the course of the disease for the original diagnosis of myeloma:
- Bone marrow plasmacytosis with > 10% plasma cells or sheets of plasma cells or biopsy proven plasmacytoma
- Must have symptomatic disease that prompted the initiation of therapy (e.g., anemia, hypercalcemia, bone disease, or renal dysfunction)
- Must have completed a minimum of 1 and a maximum of 6 courses of a dexamethasone-based regimen within the past 8 weeks, including any of the following:
- Dexamethasone alone
- Vincristine, doxorubicin, and dexamethasone
