Bortezomib, Lenalidomide and Dexamethasone Combination Therapy in Patients With Newly Diagnosed Multiple Myeloma

An Open-Label Phase I/II Study of the Safety and Efficacy of Bortezomib, Lenalidomide and Dexamethasone Combination Therapy for Patients With Newly Diagnosed Multiple Myeloma

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.
