Bone Effect of Bortezomib in Patients With Relapsed/Refractory Multiple Myeloma

Summary

The primary aim of this trial is to determine the effect of a short course (i.e., 3 cycles) of low-dose Bortezomib (Velcade) on bone remodeling and on disease progression. The dose of bortezomib used in this trial of 0.7 mg/m2 is the lowest dose which has shown efficacy in the 3 largest monotherapy trials with bortezomib. 17% of patients in the APEX, 9% patients in CREST and 24% in SUMMIT trials were treated with 0.7 mg/m2 dosages. Bortezomib will be given on days 1, 8, 15, 22 over 42 days to reduce the incidence of possible drug related side effects. OBJECTIVES: Primary Objective The primary objective of this study is to: * To evaluate the effect of Velcade at 0.7 mg/m2 dose on inducing osteoblast activation as measured by ALP and other bone markers in patients with relapsed/refractory myeloma. Secondary Objectives The secondary objectives of this study are to: * To evaluate the association between osteoblastic activation and myeloma response to Velcade. * To identify predictive factors for Velcade-associated osteoblastic activation.
