Filter by:The purpose of this study is to determine the safety and activity of SGN-40 in a weekly dosage schedule as a single agent.
This phase II trial is studying how well temsirolimus works in treating patients with relapsed or refractory multiple myeloma. Drugs used in chemotherapy such as temsirolimus work in different ways to stop cancer cells from dividing so they stop growing or die.
This trial is a phase II, randomized study of patients with multiple myeloma. All patients will receive Xcellerated T Cells, with or without prior fludarabine therapy. 15 patients in each study arm will be followed for 6 months.
This phase II trial studies how well bortezomib works in treating patients with newly diagnosed multiple myeloma. Bortezomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
The study is designed as a Phase III, multi-center trial of tandem autologous transplants versus the strategy of autologous followed by Human Leukocyte Antigen (HLA)-matched sibling non-myeloablative allogeneic transplant. Study subjects will be biologically assigned to the appropriate arm depending on the availability of an HLA-matched sibling. There is a nested randomized phase III trial of observation versus maintenance therapy following the second autologous transplant for patients on the tandem autologous transplant arm.
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of plasma cells, either by killing the cells or by stopping them from dividing. Having a stem cell transplant to replace the blood-forming cells destroyed by chemotherapy, allows higher doses of chemotherapy to be given so that more plasma cells are killed. By reducing the number of plasma cells, the disease may progress more slowly. PURPOSE: This phase II trial is studying how well autologous stem cell transplant works in treating patients with persistent or recurrent primary systemic (AL) amyloidosis.
This randomized phase III trial is studying total-body irradiation (TBI) and fludarabine phosphate to see how it works compared with TBI alone followed by donor stem cell transplant in treating patients with hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, and radiation therapy before a donor stem cell transplant helps stop the growth of cancer cells. It also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune system cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after transplant may stop this from happening. It is not yet known whether TBI followed by donor stem cell transplant is more effective with or without fludarabine phosphate in treating hematologic cancer.
RATIONALE: Darbepoetin alfa and epoetin alfa may stimulate red blood cell production and treat anemia in patients who are receiving chemotherapy. It is not yet known whether darbepoetin alfa is more effective than epoetin alfa in treating patients with anemia. PURPOSE: Randomized phase III trial to compare the effectiveness of darbepoetin alfa with that of epoetin alfa in treating anemia in patients who are receiving chemotherapy for cancer.
RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy. Sometimes the transplanted cells from a donor are rejected by the body's normal cells. Ultraviolet-B light therapy given before and after allogeneic stem cell transplantation may help prevent this from happening. PURPOSE: Clinical trial to study the effectiveness of combining ultraviolet-B light therapy with allogeneic stem cell transplantation in treating patients who have hematologic malignancies.
In recent years PBPC have replaced bone marrow as the source of hematopoietic stem cells for autologous transplantation. One of the cited advantages of this procedure is the avoidance of bone marrow harvest, which frequently requires general anesthesia. Other advantages include faster neutrophil and platelet engraftment times, faster immune recovery, decrease in the amount of tumor contamination and technical ability to obtain stem cells from patients previously considered unharvestable because of marrow fibrosis or because of prior radiotherapy to the pelvis. Filgrastim has emerged as the preferred cytokine for stem cell mobilization based on its safety profile and the positive experience in granulocyte donors however, the number of circulating CD34+ cells does not occur until the third day after starting filgrastim injections. Pegfilgrastim stimulates the production and maturation of neutrophil precursors and enhances the functions of mature neutrophils in the same manner as filgrastim. Data form normal volunteers and in studies of patients with cancer have shown prolonged serum levels of the cytokine, with "self-regulation" of pegfilgrastim levels as a function of the neutrophil count. This confers a therapeutic advantage in clinical settings by allowing a less frequent dosing.
