Consolidation Therapy With Bortezomib <= 60 Year Old Patients With Multiple Myeloma

The purpose of this study is determination of the event-free survival with and without Bortezomib consolidation therapy from the day of the first chemotherapeutic, myeloma-specific therapy measure, up to the occurrence of progression/recurrence or up to the occurrence of death.

Approximately 385 patients will be enrolled in this study. Patients will be randomly assigned to treatment or observation group in a ratio of 1:1. The study duration from screening up to the study end is up to 27 weeks. Then the patients will be observed until the last included patient has completed a 30 month post observational phase. The patients in the treatment arm will receive 4 cycles of a therapy. Each cycle lasts for a 35 days. Safety evaluations will include assessment of adverse events, vital signs, physical examination, electrocardiograms, and clinical laboratory tests.
