Filter by:This phase II trial is studying the side effects and best dose of alemtuzumab when given together with fludarabine phosphate and total-body irradiation followed by cyclosporine and mycophenolate mofetil in treating patients who are undergoing a donor stem cell transplant for hematologic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, a monoclonal antibody, such as alemtuzumab, and radiation therapy before a donor stem cell transplant helps stop the growth of cancer cells. Giving chemotherapy or radiation therapy before or after transplant also stops the patient's immune system from rejecting the donor's bone marrow stem cells. The donated stem cells may replace the patient's immune 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 the transplant may stop this from happening.
This clinical trial studies the side effects and best dose of giving fludarabine and total-body irradiation (TBI) together followed by a donor stem cell transplant and cyclosporine and mycophenolate mofetil in treating human immunodeficiency virus (HIV)-positive patients with or without cancer. Giving low doses of chemotherapy, such as fludarabine, and TBI before a donor bone marrow or peripheral blood stem cell transplant helps stop the growth of cancer or abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune 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 (CSP) and mycophenolate mofetil (MMF) after the transplant may stop this from happening.
This phase I/II trial studies whether stopping cyclosporine before mycophenolate mofetil is better at reducing the risk of life-threatening graft-versus-host disease (GVHD) than the previous approach where mycophenolate mofetil was stopped before cyclosporine. The other reason this study is being done because at the present time there are no curative therapies known outside of stem cell transplantation for these types of cancer. Because of age or underlying health status, patients may have a higher likelihood of experiencing harm from a conventional blood stem cell transplant. This study tests whether this new blood stem cell transplant method can be made safer by changing the order and length of time that immune suppressing drugs are given after transplant.
Giving chemotherapy drugs, such as R115777, isotretinoin, cytarabine, and fludarabine, before a donor bone marrow transplant or an umbilical cord transplant helps stop the growth of cancer cells. It also helps stop the patient's immune system from rejecting the donor's 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. This phase II trial is studying how well giving combination chemotherapy together with donor bone marrow or umbilical cord blood transplant works in treating children with newly diagnosed juvenile myelomonocytic leukemia
This clinical trial studies fludarabine phosphate and total-body radiation followed by donor peripheral blood stem cell transplant and immunosuppression in treating patients with hematologic malignancies. Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's 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 total-body irradiation together with fludarabine phosphate, cyclosporine, and mycophenolate mofetil before transplant may stop this from happening.
This clinical trial studies fludarabine phosphate, low-dose total-body irradiation, and donor stem cell transplant followed by cyclosporine, mycophenolate mofetil, and donor lymphocyte infusion in treating patients with hematopoietic cancer. Giving low doses of chemotherapy, such as fludarabine phosphate, and total body irradiation (TBI) before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also keep the patient's immune response from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Giving an infusion of the donor's T cells (donor lymphocyte infusion) after the transplant may help increase this 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 the transplant may stop this from happening.
