7 Clinical Trials for Various Conditions
This single-institution, phase II study is designed to test the ability to achieve donor hematopoietic engraftment while maintaining low rates of transplant-related mortality (TRM) using busulfan- and fludarabine-based conditioning regimens with busulfan therapeutic drug monitoring (TDM) for patients with various inherited metabolic disorders (IMD) and severe osteopetrosis (OP).
The purpose of this research is to explore what we believe may be a safer and more effective means of performing stem cell transplantation in patients with Osteopetrosis, using chemotherapy and radiation designed to bring about engraftment and lessen transplant mortality. Prior multi-institutional data in past studies found that approximately 30% of Osteopetrosis patients do not engraft. Therefore, in this study, we utilize a reduced intensity design of pre-transplant drugs to try to make transplants safer for this disease, as well as to provide a second infusion of stem cells in patients with matched related or unrelated donors.
The purpose of this study is to establish a registry of all children with severe, malignant osteopetrosis who are treated with Actimmune (IFN-g 1b or Interferon gamma-1b) to monitor the effects of IFN-g 1b on preventing progression of this disease and to follow the safety of patients receiving it on a long-term basis. In addition, evaluation of the possible effect of Actimmune therapy on the humoral response to normal childhood vaccinations in this same patient population will be examined.Interferon gamma is a substance that the body makes naturally.
This protocol provides expanded access to bone marrow transplants for children who lack a histocompatible (tissue matched) stem cell or bone marrow donor when an alternative donor (unrelated donor or half-matched related donor) is available to donate. In this procedure, some of the blood forming cells (the stem cells) are collected from the blood of a partially human leukocyte antigen (HLA) matched (haploidentical) donor and are transplanted into the patient (the recipient) after administration of a "conditioning regimen". A conditioning regimen consists of chemotherapy and sometimes radiation to the entire body (total body irradiation, or TBI), which is meant to destroy the cancer cells and suppress the recipient's immune system to allow the transplanted cells to take (grow). A major problem after a transplant from an alternative donor is increased risk of Graft-versus-Host Disease (GVHD), which occurs when donor T cells (white blood cells that are involved with the body's immune response) attack other tissues or organs like the skin, liver and intestines of the transplant recipient. In this study, stem cells that are obtained from a partially-matched donor will be highly purified using the investigational CliniMACS® stem cell selection device in an effort to achieve specific T cell target values. The primary aim of the study is to help improve overall survival with haploidentical stem cell transplant in a high risk patient population by limiting the complication of GVHD.
This study proposes the use of a reduced intensity chemotherapy/radiation therapy regimen followed by stem cell transplantation, as compared to standard ablative chemotherapy regimens associated with stem cell transplantation, in a population of patients with non-malignant diseases (non-cancer). Eligible patients will have a non-malignant disease in one of the following four strata: bone marrow failure syndromes, immunodeficiencies, inborn errors of metabolism, or histiocytoses. Patients will be assigned to therapy according to diagnosis. Patients will be stratified by disease into one of four strata and treatment regimens will be based on specific disease criteria and conditions. Although these diseases are non-malignant in name, they are often malignant by nature of the disease progression, treatment and associated complications.
This is a data collection study that will examine the general diagnostic and treatment data associated with the reduced-intensity chemotherapy-based regimen paired with simple alemtuzumab dosing strata designed to prevented graft failure and to aid in immune reconstitution following hematopoietic stem cell transplantation.
The objective of this study is to evaluate the efficacy of using a reduced-intensity condition (RIC) regimen with umbilical cord blood transplant (UCBT), double cord UCBT, matched unrelated donor (MUD) bone marrow transplant (BMT) or peripheral blood stem cell transplant (PBSCT) in patients with non-malignant disorders that are amenable to treatment with hematopoietic stem cell transplant (HSCT). After transplant, subjects will be followed for late effects and for ongoing graft success.
