An Open-Labeled, Randomized Study to Assess Two Different Strategies of Combining Dexamethasone and VELCADE in Patients With Relapsed Multiple Myeloma Who Have Failed Four or More Lines of Therapy
- Plasmacytomas on tissue biopsy
- Bone marrow plasmacytosis (> 30% plasma cells)
- Monoclonal IgG is > 3.5 g/dL or IgA is > 2.0 g/dL; kappa or lambda light chain
excretion is > 1 g/day on a 24 hour urine sample.
- Bone marrow plasmacytosis (10 to 30%)
- Monoclonal immunoglobulin present but of lesser magnitude than given under major
- Lytic bone lesions
