Filter by:A study to assess the safety and efficacy of eculizumab in Japanese patients with hemolytic PNH.
Unrelated matched donor (cord blood, bone marrow or peripheral blood) allogeneic stem cell transplantation (UDAlloSCT) with either myeloablative or reduced intensity conditioning will be well tolerated and result in a high degree of engraftment in patients with selected malignant and non malignant disorders.
Paroxysmal nocturnal haemaoglobinuria (PNH) is a rare disease which results in breakdown of the red blood cells and bone marrow failure. It is associated with an increased risk of blood clots. Until recently, treatment has been with blood transfusions and in patients with a blood clot, blood thinners. A new treatment called eculizumab is now standard for patients who require regular blood transfusions. It works in the majority of patients by preventing the breakdown of red blood cells. This can eliminate the need for blood transfusion and reduce the risk of blood clots. It is not well understood why patients with PNH are at high risk of blood clots. The investigators plan to use specialised blood tests to assess the stickiness of the blood before starting eculizumab treatment and monthly after starting treatment. The investigators will compare these tests with standard tests of clotting.
The purpose of this study is to look at whether the combination of lower-dose chemotherapy with two chemotherapy (anti-cancer) drugs, called busulfan and melphalan, and an antibody medication called alemtuzumab (Campath®), can prevent rejection of donor blood stem cells so that those cells take hold and build a healthy new blood cell factory after transplant. The study will also look at the safety of the combination of drugs and of the transplant of peripheral blood stem cells from a healthy relative or an unrelated donor.
The purpose of this study is to compare the effects (good and bad) of the medication basiliximab in combination with cyclosporine (investigational therapy) for the prevention of a complication of bone marrow transplantation known as graft-versus-host disease (GVHD). GVHD is a complication in which the cells of the transplanted bone marrow react against organs and tissues.
To determine the time to and rate of hematologic engraftment following unrelated umbilical cord blood transplantation in adults with one or two cord blood units using total body irradiation and fludarabine as the transplant conditioning regimen and cyclosporine/MMF as graft-versus-host disease prophylaxis.
The primary objective of this study was to evaluate the pharmacokinetic (PK) and pharmacodynamic (PD) parameter estimates of eculizumab to confirm the dose regimens for pediatric and adolescent participants with PNH.
This clinical trial is studying how well giving fludarabine phosphate and melphalan together with total-body irradiation followed by donor stem cell transplant works in treating patients with hematologic cancer or bone marrow failure disorders. Giving low doses of chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells or abnormal cells. It may also 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 or abnormal cells (graft-versus-tumor effect)
Randomized comparison of cyclophosphamide versus reduced-dose cyclophosphamide plus fludarabine in addition to anti-thymocyte globulin for the conditioning therapy in allogeneic hematopoietic cell transplantation for bone marrow failure syndrome.
RATIONALE: Giving low doses of chemotherapy and antithymocyte globulin before a donor stem cell transplant helps stop the growth of abnormal cells. It may also 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 abnormal cells (graft-versus-tumor effect). PURPOSE: This phase II trial is studying how well a donor stem cell transplant works after busulfan, fludarabine, methylprednisolone, and antithymocyte globulin in treating patients with bone marrow failure syndrome.
