The pre-treatment period includes the screening visit in which participants provide informed consent in writing in order to take part in the study. The patient is then assessed to determine his/her eligibility. The selection process will begin 21 days before the first dose of medication is administered (days -21 to 0). During the treatment period, eligible patients will be included in the study and given six cycles of induction treatment with bortezomib/ lenalidomide / dexamethasone (VRD-GEM). Each cycle will last 28 days, during which SC bortezomib will be administered on days 1, 4, 8 and 11, oral lenalidomide on days 1-21 of each cycle, and oral dexamethasone on days 1-4 and 9-12 of the cycle.
