Filter by:The trial will evaluate the effects of aerobic exercise in patients undergoing chemotherapy for the treatment of a hematological neoplastic disease.
The study evaluates the effects of a supervised exercise program on the physical performance, the mood and the complications of therapy in patients undergoing a high-dose chemotherapy followed by an autologous peripheral blood stem cell transplantation.
In stem cell transplantation as treatment for malignant diseases, calcineurin inhibitors like cyclosporine A are commonly used to prevent tissue destruction (GvHD) by activated donor immune cells. The hypothesis for this study is, that replacing calcineurin inhibitors by everolimus and mycophenolate as GvHD prophylaxis not only reduces toxicity of the treatment but also improves tolerance induction of the donor T cells toward the host, eventually increasing the safety of stem cell transplantation.
Compared to other stemcell sources cord blood (CB) is easier and safer to procure, has no donor attrition, a limitless supply, reduced viral transmission, less acute & chronic GVHD, is rich in hematopoietic progenitor cells, and immaturity of T-cell-mediated immunity. CB has delayed neutrophil and platelet engraftment, a prolonged immune reconstitution, uncertain graft-vs-tumor activity, and cell doses from single CB units (U) are a limiting factor for larger recipients Using the intravenous route (IV), a close match between the patient (pts) and the donor or CBU can improve a pts outcome after transplant. Even though a closely matched CBU is preferred, the studies suggest the match may not have to be as close as is needed for marrow or peripheral blood transplants If one has an uncommon tissue type, the doctor may not find a closely matched adult donor and a CBU may be an option, are stored and ready to use. GVHD is a complication after an allogeneic transplant. Studies founded that after a CBtransplant, fewer pts get GVHD than after marrow or peripheral blood transplants. Pts in the studies who did get GVHD after CBtransplant tended to get less severe cases We hypothesized that direct intrabone transplant of CBcells could improve haematologic recovery due to a better stem cell homing, based on the following observations: stem cells recirculate in animals irradiated with limb shielding; a limited fraction (10-15%) of cells injected iv to the haematopoietic sites, possibly because the large majority is lost in other organs; in a mousemodel, HSC directly injected ib repopulated the marrow of lethally irradiated mice 10times more efficiently than HSC cells injected iv; delayed engraftment after CB transplant is possibly not caused by insufficient stem cell numbers; indeed, children grafted with CB cells have superior stem cell reservoir 1year posttransplant when compared to marrow transplant recipients Based on these data, we set-up a phase I-II study to evaluate whether ib injection could be safely performed and whether this procedure could ensure engraftment and shorten the time of complete hematopoietic recovery in adults with high risk haematopoietic malignancies compared to the published data. Neutrophil recovery >80% at day60 and Platelets recovery >80% at days100 were defined as success. 1° endpoint was the probability of neutrophils and platelets recovery after ib CB transplant, 2° included incidence of acute GVHD, relapse, overall survival
The purpose of this study is to maintain a comprehensive registry of patients with the rare inherited bone marrow failure syndrome Diamond Blackfan anemia (DBA).
