The purpose of the study in Phase I is to select the recommended dose of bortezomib in combination with melphalan and prednisolone in Japanese participants. In Phase II, to assess the effectiveness and safety of the recommended dose of bortezomib (selected in the phase I portion).
This is an open-label (both physician and participant know the intervention), non-randomized (participants are not assigned by chance), multi-center study in untreated multiple myeloma participants who were not candidates for hematopoietic stem cell transplant. This study consists of two parts: Phase I and Phase II. In Phase I, a total of 18 participants will be enrolled ie, 6 patients per dose level (0.7, 1.0 and 1.3 mg/m2) to determine the recommended dose of bortezomib. In Phase II, additional 83 participants will be enrolled. Safety evaluations will include assessment of adverse events, clinical laboratory test, specifically hematological toxicities.

Number of Participants With Dose Limiting Toxicity During the Phase I (Cycle 1)
Dose limiting toxicity defined as an adverse event or adverse drug reaction experienced by the participants during 6 weeks of treatment Cycle 1
Time frame: 6 weeks
Number of Participants With Overall Response (Complete Response [CR] + Partial Response [PR]) - Phase I and II
Response is evaluated as per the criteria for evaluating disease response and progression in patients with multiple myeloma treated by high-dose therapy and haemopoietic stem cell transplantation (Blade et al. 1998). CR: disappearance of the original monoclonal protein from the blood and urine and \<5% plasma cells in the bone marrow on at least 2 determinations for a minimum of 6 weeks; no increase in the size or number of lytic bone lesions; disappearance of soft tissue plasmacytomas for at least 6 weeks. PR: ≥50% reduction in the level of serum monoclonal protein for at least 2 determinations 6 weeks apart; If present, reduction in 24-hour urinary light chain excretion by either ≥90% or to \<200 mg for at least 2 determinations 6 weeks apart; ≥50% reduction in the size of soft tissue plasmacytomas for at least 6 weeks; no increase in size or number of lytic bone lesions
Time frame: 54 weeks
