This is a randomized, open label, multicenter clinical trial to compare the efficacy and safety of Velcade (bortezomib) and dexamethasone versus Velcade, thalidomide, and dexamethasone versus Velcade, melphalan, and prednisone in patients with previously untreated multiple myeloma not considered candidates for high-dose chemotherapy and autologous stem cell transplantation.

Detailed description:

Arms:
arm 1: Participants received bortezomib (Velcade) 1.3 mg/m\^2 administered as a bolus intravenous (IV) injection on Days 1, 4, 8, and 11, and dexamethasone 20 mg orally on Days 1, 2, 4, 5, 8, 9, 11 and 12 for eight 21-day treatment cycles (Induction).
