Filter by:This is a 2-phase study during which patients with relapsed or refractory multiple myeloma (MM) or plasma cell leukemia (PCL), who have already received at least two previous treatments, will receive investigational study drug ARRY-520. The study has 3 parts. In the first part of the study, Phase 1, patients will receive increasing doses of study drug, with or without granulocyte-colony stimulating factor (G-CSF) support, in order to achieve the highest dose possible that will not cause unacceptable side effects. Approximately 30 patients from the US will be enrolled in Part 1 (Active, not recruiting). In the second part of the study, Phase 2, patients will receive the best dose of study drug determined from the first part of the study and will be followed to evaluate what side effects the study drug causes and what effectiveness it has, if any, in treating the cancer. Approximately 30 patients from the US will be enrolled in Part 2 (Active, not recruiting). In the third part of the study, Phase 2 with Dexamethasone, patients will receive the best dose of the study drug determined from the first part of the study, in combination with dexamethasone, and will be followed to evaluate what side effects the combination causes and what effectiveness the combination has, if any, in treating the cancer. Approximately 50 patients from the US will be enrolled in Part 3 (Active, not recruiting).
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.
