QUIREDEX: Revlimid (Lenalidomide) and Dexamethasone (ReDex) Treatment Versus Observation in Patients With Smoldering Multiple Myeloma With High Risk of Progression (QUIREDEX)

The primary objective is to evaluate when Revlimid and Dexamethasone treatment extend the time to progression to symptomatic MM in patients with smoldering MM. The second one is to evaluate the efficacy of the treatment in response rate terms. Otherwise this study wants to evaluate the safety and tolerability of the treatment
