Filter by:This is a study to collect the outcomes of stem cell transplantation for patients with hematologic diseases other than cancer.
This study will evaluate pediatric patients with malignant or non-malignant blood cell disorders who are having a blood stem cell transplant depleted of T cell receptor (TCR) alfa and beta cells that comes from a partially matched family donor. The study will assess whether immune cells, called T cells, from the family donor, that are specially grown in the laboratory and given back to the patient along with the stem cell transplant can help the immune system recover faster after transplant. As a safety measure these T cells have been programmed with a self-destruct switch so that they can be destroyed if they start to react against tissues (Graft versus host disease).
This study's goal is to determine the frequency and severity of acute graft versus host disease, to evaluate incidence of primary and secondary graft rejection, to assess event free survival and overall survival, to determine the time to neutrophil and platelet engraftment, to determine the time to immune reconstitution (including normalization of T, B and natural killer (NK) cell repertoire and Immunoglobulin G production), and to establish the incidence of infectious complications including bacterial, viral, fungal and atypical mycobacterial and other infections following CD34+ selection in children, adolescents and young adults receiving an allogeneic peripheral blood stem cell transplant from a family member or unrelated adult donor for a non-malignant disease.
This is a single arm, phase I study to assess the tolerability of abatacept when combined with cyclosporine and mycophenolate mofetil as graft versus host disease prophylaxis in children undergoing unrelated hematopoietic stem cell transplant for serious non-malignant diseases as well as to assess the immunological effects of abatacept. Participants will be followed for 2 years.
The purpose of this study is to demonstrate that a sufficient number of iron-overloaded thalassemia (THAL), Sickle Cell Disease (SCD)and Diamond Blackfan Anemia (DBA) populations with similar duration of chronic transfusion, and age at start of transfusions would be available for a confirmatory study. The study will examine the hypothesis that a chronic inflammatory state in SCD leads to hepcidin- and cytokine-mediated iron withholding within the RES (reticuloendothelial system), lower plasma NTBI (non-transferrin bound iron) levels, less distribution of iron to the heart in SCD.
The main purpose of this study is to examine the outcome of a combined bone marrow and kidney transplant from a partially matched related (haploidentical or "haplo") donor. This is a pilot study, you are being asked to participate because you have a blood disorder and kidney disease. The aim of the combined transplant is to treat both your underlying blood disorder and kidney disease. We expect to have about 10 people participate in this study. Additionally, because the same person who is donating the kidney will also be donating the bone marrow, there may be a smaller chance of kidney rejection and less need for long-term use of anti-rejection drugs. Traditionally, very strong cancer treatment drugs (chemotherapy) and radiation are used to prepare a subject's body for bone marrow transplant. This is associated with a high risk for serious complications, even in subjects without kidney disease. This therapy can be toxic to the liver, lungs, mucous membranes, and intestines. Additionally, it is believed that standard therapy may be associated with a higher risk of a complication called graft versus host disease (GVHD) where the new donor cells attack the recipient's normal body. Recently, less intense chemotherapy and radiation regimens have been employed (these are called reduced intensity regimens) which cause less injury and GVHD to patients, and thus, have allowed older and less healthy patients to undergo bone marrow transplant. In this study, a reduced intensity regimen of chemotherapy and radiation will be used with the intent of producing fewer toxicities than standard therapy. Typical therapy following a standard kidney transplant includes multiple lifelong medications that aim to prevent the recipient's body from attacking or rejecting the donated kidney. These are called immunosuppressant drugs and they work by "quieting" the recipient's immune system to allow the donated kidney to function properly. One goal in our study is to decrease the duration you will need to be on immunosuppressant drugs following your kidney transplant as the bone marrow transplant will provide you with the donor's immune system which should not attack the donor kidney.
The purpose of this clinical trial is to investigate the safety of human placental-derived stem cells (HPDSC) given in conjunction with umbilical cord blood (UCB) stem cells in patients with various malignant or nonmalignant disorders who require a stem cell transplant. Patients will get either full dose (high-intensity) or lower dose (low intensity) chemo- and immunotherapy followed by a stem cell transplantation with UCB and HPDSC.
This phase II trial studies how well giving fludarabine phosphate, melphalan, and low-dose total-body irradiation (TBI) followed by donor peripheral blood stem cell transplant (PBSCT) works in treating patients with hematologic malignancies. Giving chemotherapy drugs such as fludarabine phosphate and melphalan, and low-dose TBI before a donor PBSCT helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from the 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 cell from a donor can make an immune response against the body's normal cells. Giving tacrolimus, mycophenolate mofetil (MMF), and methotrexate after transplant may stop this from happening
The purpose of this study is to determine the safety and dosing of drug Sotatercept, as a subcutaneous injection, to stimulate production of red blood cell production. To be given every 28 days for up to four doses.
The goal of this research study is to establish chimerism and avoid graft-versus-host disease in patients with hemoglobinopathies.
