The purpose of this study is to determine the safety and efficacy of the bortezomib, lenalidomide and dexamethasone combination in patients with newly diagnosed multiple myeloma. We are looking for the highest dose of the combination that can be given safely and see how well it works as a combination in newly diagnosed patients.
* The safe dose of dexamethasone is already known. The dose of bortezomib and lenalidomide will be increased during the study until the best and safest amount (or dose) is identified. The participant's dose of the study drugs will depend on when they enter the study. * In this study each cycle will be 21 days and participants will begin the study medication in the clinic on Cycle 1 Day 1. Lenalidomide (capsules) will be taken daily for the first 2 weeks only (Day 1-14). Dexamethasone (tablets) will be taken on Day 1, 2, 4, 5, 8, 9, 11 and 12. Bortezomib will be given intravenously in the outpatient treatment clinic on Day 1, 4, 8 and 11. The third week is a rest period and no study medication will be given. * During the course of the study treatment, tests and procedures will be performed at designated time periods. This includes; medical history updates, physical/neurological examinations, skeletal survey (x-rays or scan), blood samples, optional bone marrow aspiration/tissue biopsy, urine samples, 12-lead ECG, and MRI/CT scan (if needed). * It is expected that study participants will receive study treatment for 8 cycles (168 days). If the participant completes the first 8 cycles of the study, has stable or responding disease and has not experienced bad side effects, they will be allowed to continue treatment on a maintenance schedule, detailed in the protocol, at the study doctor's discretion.

Objective Response Rate of the Drug Combination in This Patient Populations.
Overall Response (OR) was defined as partial response (PR) or better. Response was assessed according to European Group for Blood and Marrow Transplant criteria, modified to include nCR and VGPR, from the International Uniform Response Criteria.
Time frame: Full response assessment was conducted at the end of cycle 8 (average of168 days) and after cycle 4 (84 days) for patients proceeding to transplant.
Estimated 18-month Progression Free Survival (PFS) Rate
PD from European Bone Marrow Transplant (EBMT) Response Criteria Required one or more: \>25% increased in the level of serum monoclonal paraprotein, which must also be an absolute increase of at least 5 g/L and confirmed on a repeat investigation, or \>25% increased in 24-hour urinary light chain excretion (must also be an absolute increase of at least 200 mg/24 h and confirmed on a repeat investigation), or \>25% increased in plasma cells in a bone marrow aspirate or biopsy (must also be an absolute increase of at least 10%) Definite increase in the size of existing lytic bone lesions or soft tissue plasmacytomas. Development of new bone lesions or soft tissue plasmacytomas (not including compression fracture). Development of hypercalcemia (corrected serum calcium \>11.5 mg/dL or 2.8 mmol/L not attributable to any other cause). PFS was measured from treatment initiation to progression or death, censored at the date patients were last known to be alive and disease free
Time frame: PFS rate at 18 months
Percentage of Patients Who Remained in Response for More Than 18 Months
Duration of response was measured from first response to progression or death, censored at the date patients were last known to be alive and disease free for patients who had not progressed or died.
Time frame: Response rate at 18 months
Estimated 18-month Overall Survival Rate
Overall survival was measured from treatment initiation to death, censored at the date patients were last known to be alive for those who had not died.
