Filter by:The primary objectives of this study are to: - To determine the maximum tolerated dose (MTD) of bortezomib in combination with high-dose melphalan as a conditioning regimen. - To determine the safety, tolerability, and response rates of bortezomib given in combination with high-dose melphalan, as a conditioning regimen, for tandem transplants in patients with primary refractory multiple myeloma or plasma cell leukemia. The secondary objectives of this study are to: - To determine gene expression profiles (pharmacogenomics) and perform RTPCR for Fanconi anemia pathway genes, prior to and after treatment with bortezomib, in patients with primary refractory multiple myeloma and plasma cell leukemia and correlate profiles with responses to treatment. - To determine the time to disease progression and overall survival in patients with primary refractory multiple myeloma and plasma cell leukemia treated with bortezomib followed by tandem autologous transplantation - To determine the response rates of 2 cycles of bortezomib in patients with primary refractory multiple myeloma or plasma cell leukemia
This phase I/II trial studies whether a new kind of blood stem cell (bone marrow) transplant, that may be less toxic, is able to treat underlying blood cancer. Stem cells are "seed cells" necessary to make blood cells. Researchers want to see if using less radiation and less chemotherapy with new immune suppressing drugs will enable a stem cell transplant to work. Researchers are hoping to see a mixture of recipient and donor stem cells after transplant. This mixture of donor and recipient stem cells is called "mixed-chimerism". Researchers hope to see these donor cells eliminate tumor cells. This is called a "graft-versus-leukemia" response.
