A Trial of Tandem Autologous Stem Cell Transplants +/- Post Second Autologous Transplant Maintenance Therapy vs Single Autologous Stem Cell Transplant Followed by Matched Sibling Non-myeloablative Allogeneic Stem Cell Transplant for Patients With Multiple Myeloma (BMT CTN #0102)
In Brief
A Phase 3 clinical trial evaluating One Autologous Transplant, Non-Myeloablative Allogeneic Transplant, and 4 other interventions for Multiple Myeloma. Completed, enrolled 710 participants across 36 sites.
Detailed Summary
The study is designed as a Phase III, multi-center trial of tandem autologous transplants versus the strategy of autologous followed by Human Leukocyte Antigen (HLA)-matched sibling non-myeloablative allogeneic transplant. Study subjects will be biologically assigned to the appropriate arm depending on the availability of an HLA-matched sibling. There is a nested randomized phase III trial of observation versus maintenance therapy following the second autologous transplant for patients on the tandem autologous transplant arm.

Interventions
Melphalan will be administered at a dose of 200 mg/m2. Melphalan will be given in one dose infused on Day -2. Melphalan dose is based on ideal body weight (IBW) for patients who weigh 100-120% of their IBW. All patients will receive an autologous graft with a minimum cell dose of 2.0 x 106 CD34+ cells/kg patient weight. Patients will receive \~5 ug/kg/day of Granulocyte-Colony Stimulating Factor (G-CSF) subcutaneously from Day 5 post-transplant until absolute neutrophil count (ANC) \> 500/mm3 for two days.
Upon recovery and at least Day 60 post-autograft, patients with an available 6/6 HLA matched sibling will receive an allograft after non-myeloablative conditioning. Day 0 patients will receive Total Body Irradiation (TBI) 2.0 Gy from a linear accelerator ≤ 20 cGy/min, followed by allogeneic peripheral blood stem cell (PBSC) infusion. Commence cyclosporine (CSA) on Day -3 at 5 mg/kg bid PO for a daily dose of 10 mg/kg/day through Day +84 based on actual body weight. Starting on Day 84, patients in partial or complete response with the absence of graph versus host disease (GVHD) will have CSA tapered so the patient will be off CSA by Day 180. Oral administration of Mycophenolate Mofetil will be at a daily dose of 30 mg/kg/day from the evening of Day 0 until Day 27 post-transplant.
Upon recovery from the first autograft, but at least 60 days (preferably between 60-120 days) after the first autograft, patients without an HLA-matched sibling donor will receive a second autograft, also conditioned with melphalan 200 mg/m2.
Patients will be initiated on a starting dose of 50 mg/day. The dose will be increased weekly by 50 mg as tolerated to achieve a target dose of 200 mg/day. Patients will be treated for 12 months with thalidomide.
Patients will receive dexamethasone at a dose of 40 mg per day during Days 1-4 of each month for 12 months. The first dose of dexamethasone to be given the same day the patient starts thalidomide.
One year of observation post-transplants.
