Healthy volunteers: no

Brief summary:
The study is designed as a Phase III, multicenter trial of tandem autologous transplants plus maintenance therapy versus the strategy of single autologous transplant plus consolidation therapy with lenalidomide, bortezomib and dexamethasone (RVD) followed by maintenance therapy or single autologous transplant plus maintenance therapy as part of upfront treatment of multiple myeloma (MM). Lenalidomide will be used as maintenance therapy for three years in all arms.

Detailed description:
The primary objective of the randomized trial is to compare three-year progression-free survival (PFS) between the three treatment arms as a pairwise comparison. Mobilization therapy will not be specified for the study. Randomization to three treatment arms will be done prior to the first transplants. All patients will undergo a first autologous peripheral blood stem cell (PBSC) transplant with high-dose melphalan (200 mg/m\^2 IV) given on Day -2. Upon recovery from the first transplant patients will receive either a second autologous PBSC transplant with the same conditioning regimen as the first transplant or consolidation therapy with RVD (lenalidomide 15 mg/day on Days 1-14, dexamethasone 40 mg on Days 1, 8 and 15, and bortezomib 1.3mg/m\^2 on Days 1, 4, 8 and 11 of every 21 day cycle, patients will receive four cycles) or maintenance with lenalidomide (15 mg daily). All patients will also receive maintenance lenalidomide which will start after the second transplant, after the first autologous transplant or after consolidation therapy depending on the treatment arm. Maintenance therapy with lenalidomide will start at 10 mg daily for three months and increase to 15 mg daily. The duration of maintenance will be three years in all treatment arms.

Arms:
arm 1: Initial autologous transplant followed by a second autologous transplant and lenalidomide maintenance arm 2: Initial autologous transplant followed by lenalidomide, bortezomib and dexamethasone (RVD) consolidation and lenalidomide maintenance arm 3: Initial autologous transplant followed by lenalidomide maintenance

Interventions: intervention 1: Lenalidomide intervention 2: lenalidomide, bortezomib and dexamethasone intervention 3: Lenalidomide
Intervention descriptions: intervention 1: All patients will undergo a first autologous peripheral blood stem cell (PBSC) transplant with high-dose melphalan (200 mg/m\^2 IV) given on Day -2. Upon recovery from the first transplant patients will receive a second autologous PBSC transplant with the same conditioning regimen as the first transplant. All patients will also receive maintenance lenalidomide which will start after the second transplant. Maintenance therapy with lenalidomide will start at 10 mg daily for 3 months and increase to 15 mg daily. The duration of maintenance will be three years in all treatment arms. intervention 2: All patients will undergo a first autologous peripheral blood stem cell (PBSC) transplant with high-dose melphalan (200 mg/m\^2 IV) given on Day -2. Upon recovery from the first transplant patients will receive consolidation therapy with RVD (lenalidomide 15 mg/day on Days 1-14, dexamethasone 40mg on Days 1, 8 and 15, and bortezomib 1.3mg/m2 on Days 1, 4, 8 and 11 of every 21 day cycle, patients will receive four cycles). All patients will also receive maintenance lenalidomide which will start after consolidation therapy. Maintenance therapy with lenalidomide will start at 10 mg daily for 3 months and increase to 15 mg daily. The duration of maintenance will be three years in all treatment arms. intervention 3: All patients will undergo a first autologous peripheral blood stem cell (PBSC) transplant with high-dose melphalan (200 mg/m\^2 IV) given on Day -2. Upon recovery from the first transplant patients will receive maintenance with lenalidomide (15 mg daily). Maintenance lenalidomide will start after the first autologous transplant. Maintenance therapy with lenalidomide will start at 10 mg daily for 3 months and increase to 15 mg daily. The duration of maintenance will be three years in all treatment arms.
