Brief Summary: To evaluate the toxicity and tolerability of this tandem autologous/allogeneic transplant approach for patients with advanced stage multiple myeloma.

Detailed Description: Development of cell-based immunotherapy from allogeneic hematopoietic cell transplantation (HCT) is dependent upon stable T-cell engraftment and the success of this therapeutic approach is likely to be greatest when directed against a minimal rather than gross tumor burden. To this end, tandem transplants with high dose therapy and autologous hematopoietic cell transplantation (AHCT) for tumor cytoreduction followed by non-myeloablative allotransplant have been conducted. In myeloma, this tandem approach results in greater efficacy compared to conventional AHCT.

Group	Intervention	Description
Autologous-Allogeneic Peripheral Blood Stem Cell Transplant	Mycophenolate Mofetil 250mg	Study treatment is a high-dose sequential chemotherapy approach to hematopoietic stem cell (HSC) transplant that uses an autologous peripheral blood stem cell (auto-PBSC) transplant followed by allogeneic peripheral blood stem cell (allo-PBSC) transplant to evaluate improved graft vs host disease (GvHD) control. Participant auto-PBSC are mobilized with cyclophosphamide (also to provide cytoreduction) and filgrastim, followed by melphalan as an auto-PBSC conditioning agent, then auto-PBSC infusion. For the allo-PBSC transplant, donors are mobilized with filgrastim, and participants receive a regimen of total lymphoid irradiation and anti-thymocyte globulin (TLI/ATG), followed by infusion of donor allo-PBSC. Solumedrol, diphenhydramine, acetaminophen, and hydrocortisone are administered as premedications, and rabbit anti-thymocyte globulin (ATG) plus mycophenolate mofetil (MMF) are administered for post-allo-PBSC immunosuppression.
