Dose-Reduced Allogeneic Stem Cell Transplantation After Autologous High-Dose Chemotherapy in Patients With Multiple Myeloma
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
To evaluate the feasibility and efficacy of a autologous stem cell transplantation followed by a Melphalan/ Fludarabine based dose-reduced allograft from HLA-identical and HLA-compatible unrelated donor in patients with Multiple Myeloma. In those with non complete remission DLI and/ or new agents such as Bortezomib, Thalidomid or Lenalidomide can be used to upgrade remission.
Safety and efficacy of a conditioning regimen with Fludarabine, Melphalan and ATG prior allogeneic SCT after high dose chemotheraoie and autologous SCT. Evaluation of underlying disease and donor-recipient-chimerism.
Secondary Outcome Measures
Evaluation of engraftment of leucocytes and platelets
