Phase 2 Study of Autologous Followed by Nonmyeloablative Allogeneic Transplantation Using TLI & ATG

September 19, 2017 updated by: Wen-Kai Weng, Stanford University

A Phase 2 Study of Autologous Followed by Nonmyeloablative Allogeneic Transplantation Using Total Lymphoid Irradiation (TLI) and Antithymocyte Globulin (ATG) in Multiple Myeloma Patients

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

Study Overview

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Autologous-Allogeneic Peripheral Blood Stem Cell Transplant
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.

Auto-PBSC ≥ 2 to 3 x 10e6 CD34+ cells/kg are intravenously (IV) infused as part of the combination stem cell therapy.

and allogeneic stem cells are administered intravenous (IV) infusion to reestablish hematopoietic function in patients whose bone marrow or immune system is damaged or defective
