Filter by:Bone marrow stem cell transplants (otherwise called bone marrow transplants) from healthy donors are sometimes the only means of curing hematological malignant diseases such as acute and chronic leukemias, myelodysplastic syndrome, myeloproliferative diseases and lymphomas. Before transplant the patient receives chemotherapy and radiation treatment to reduce the malignancy to low levels and to prevent rejection of the transplant. The transplant restores the blood counts to normal and replaces the patients immunity with that of the donor. The donors immune cells increase the effect of the transplant by attacking remaining malignant cells. Donor immune cells (especially those called T lymphocytes) also attack healthy non-cancerous cells and tissues of the recipient causing "graft-versus-host-disease" (GVHD). Strong GVHD reactions occurring within weeks after the transplant can be life-threatening . In this study we remove most of the T lymphocytes from the transplant to minimize the risk of GVHD. However to improve immunity against residual malignant cells and boost immunity to infections, donor T cells (stored frozen at time of transplant) are given back around 90 days after the transplant when they have a reduced risk of causing serious GVHD. Any patient between 10 and 75 years of age with acute or chronic leukemia, myelodysplastic syndrome, myeloproliferative syndromes or lymphoma, who have a family member who is a suitable stem cell donor may be eligible for this study. Candidates are screened with a medical history and various tests and examinations.
Patients with advanced chronic lymphocytic leukemia (CLL) have a poor long-term prognosis. Allogeneic stem cell transplantation (SCT) in patients with CLL has only rarely been performed in the past because the clinical outcome after myeloablative conditioning was poor, mainly due to the high treatment-related mortality. However long-term disease-free survival after allogeneic SCT has been reported. Recently it has been demonstrated by our group and others that non-relapse mortality can be reduced significantly with the use of reduced-intensity conditioning regimens. Yet, graft versus host disease (GVHD) remains an important problem in this setting. Alemtuzumab is an effective drug for the treatment of patients with advanced CLL and has been successfully applied for GVHD-prophylaxis in the setting of myeloablative and reduced-intensity conditioning regimens. The goal of the present study is to evaluate the role of alemtuzumab as part of a fludarabine-based reduced intensity conditioning regimen for allogeneic SCT in patients with advanced CLL.
The purpose of this study is to determine whether the combination of alemtuzumab and rituximab is safe and effective in treating patients with relapsed Chronic Lymphocytic Leukemia (CLL) and to determine whether alemtuzumab can be given as a single weekly subcutaneous dose, together with rituximab.
The purpose of the study is to evaluate the effects of increasing doses of CNF1010 on pharmacodynamic markers and hematological response.
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer-killing substances to them. Giving more than one drug (combination chemotherapy) together with rituximab may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving combination chemotherapy together with rituximab works in treating patients with chronic lymphocytic leukemia (CLL) that has not responded to fludarabine (closed to entry as of 10/2006), CLL with autoimmune hemolytic anemia, or Richter transformation.
RATIONALE: Giving chemotherapy drugs, such as fludarabine and cyclophosphamide, and total-body irradiation before a donor umbilical cord blood stem cell transplant helps stop the growth of cancer cells and prepares the patient's bone marrow for the stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil may stop this from happening. PURPOSE: This phase II trial is studying how well giving fludarabine and cyclophosphamide together with total-body irradiation works in treating patients who are undergoing an umbilical cord blood transplant for hematologic cancer.
The primary purpose of this study is to evaluate the safety, toxicities, dosage and response rate for an investigational drug, motexafin gadolinium, administered to patients with chronic lymphocytic leukemia or small lymphocytic lymphoma. The secondary purpose of this study is to evaluate the clinical benefit rate, the time it takes for a patient's chronic lymphocytic leukemia or small lymphocytic lymphoma to worsen, the duration of response and the time during which patients survive without chronic lymphocytic leukemia or small lymphocytic lymphoma worsening. Additionally, the patient's response to motexafin gadolinium will be compared to the response of the patient's cells in a laboratory to motexafin gadolinium.
This is an open-label Phase 2 study to evaluate the safety and efficay of AT-101 in combination with rituximab in patients with relapsed or refractory chronic lymphocytic leukemia.
The purpose of this study is to determine whether SPC2996 is effective and safe in the treatment of Chronic Lymphocytic Leukaemia (CLL)
RATIONALE: Giving chemotherapy before a donor bone marrow transplant helps stop the growth of cancer cells. It also helps stop the patient's immune system from rejecting the donor's stem cells. Also, monoclonal antibodies, such as alemtuzumab, can find cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving methotrexate, cyclosporine and mycophenolate mofetil after the transplant may stop this from happening. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer cells as not belonging in the patient's body and destroy them (called graft-versus-tumor effect). Giving an infusion of the donor's white blood cells (donor lymphocyte infusion) may boost this effect. PURPOSE: This phase I/II trial is studying the side effects of giving fludarabine together with cyclophosphamide and to see how well they work in treating patients who are undergoing donor stem cell transplant for B-cell chronic lymphocytic leukemia or Waldenström's macroglobulinemia.
