Brief summary
The purpose of this study is to evaluate the safety and effectiveness of bortezomib in combination with a standard regimen of cyclophosphamide and dexamethasone.
Detailed description
This is open-label (both the participant and the investigator know what treatment participants will receive), prospective (participants are identified and then followed forward in time for the outcome of the study), multi-centre, and non-randomized (participants are assigned to different treatment groups by the investigator) study. The study will be conducted into 2 parts (Part 1 and Part 2). Approximately 400 participants will be enrolled (30 in Part 1 and 370 in Part 2). In Part 1 the optimum dose of cyclophosphamide will be evaluated and in Part 2 the selected dose of cyclophosphamide from Part 1 will be administered. Part 2 will include a screening period of a maximum of 14 days followed by chemotherapy (bortezomib, cyclophosphamide, and dexamethasone) of a maximum of three 21-day cycles. Safety will be evaluated by the assessment of adverse events, vital signs, physical examination, electrocardiogram, and clinical laboratory tests which will be monitored throughout the study.
Interventions
In Part 1, cyclophosphamide with dose ranging from 900 to 1500 mg will be administered intravenously on Day 1 of each 21 day cycle for 3 cycles to determine optimal dose. In Part 2, optimal dose determined in Part 1 will be administered on Day 1 of each 21 day cycle for 3 cycles.
Bortezomib 1.3 mg/m2 will be administered intravenously on Days 1,4,8, and 11 of each 21 day cycle for 3 cycles in both parts (Part 1 and Part 2).
Participants will receive dexamethasone 40 mg orally or intravenously on Days 1, 2, 4, 5, 8, 9, 11, and 12 of each 21 day cycle for 3 cycles in both parts (Part 1 and Part 2).
