Filter by:Fludarabine is a chemotherapy drug used extensively in bone marrow transplantation. The goal of this study is to determine what causes some children to have different drug concentrations of fludarabine in their bodies and if drug levels are related to whether or not a child experiences severe side-effects during their bone marrow transplant. The hypothesis is that clinical and genetic factors cause changes in fludarabine drug levels in pediatric bone marrow transplant patients and that high levels may cause severe side-effects.
This is a multi-center, phase 1, open-label first-in-human study of AMG 319 in subjects with relapsed or refractory lymphoid malignancies. This study consists of two parts. The dose exploration in part 1, studies cohorts of 3 subjects with relapsed or refractory lymphoid malignancies and uses a practical continuous reassessment model [CRM] to guide dose escalation and to define the MTD. The dose expansion in part 2 will enroll 20 subjects with CLL at a dose no higher than the MTD and further explore the safety, PK, and clinical activity of AMG 319 in this patient population.
The purpose of this study is to examine the safety and tolerability of CA-18C3 in subjects with hematologic malignancies, as well as look at the preliminary efficacy of IL-1alpha blockade.
Transfusion of red blood cells (RBCs) is important for the care of patients undergoing stem cell transplantation. Stem cell transplants are used to treat blood cancers and bone marrow disorders. This involves the use of high doses of chemotherapy and/or radiation to kill cancer cells; but this damages the marrow and blood system. Blood stem cells are transplanted by infusing into the recipient and blood counts recover over 2-3 weeks. Before bone marrow recovery, RBCs are needed to support the patient. Higher hemoglobin in these high risk patients may have benefits such as better energy and organ function. However, research in other areas of medicine suggests that a higher red cell count may be dangerous. Taken together, it is unclear whether having a lower or higher red cell count is better for patients having a blood stem cell transplant. The investigators plan to study this by randomly assigning patients having a transplant to be transfused with RBCs either at a higher or lower hemoglobin level. In this way, the investigators will be able to accurately find out if there are any benefits or harms in having a lower or higher red cell count during the recovery period after blood stem cell transplantation.
The purpose of the Phase IIA study are to: 1. define the safety profile 2. evaluate the efficacy of a sequential infusion of unmanipulated Donor Lymphocyte Infusions (DLI) and Cytokine Induced Killer (CIK) cells for the treatment of molecular, cytogenetic or hematologic relapse after hematopoietic stem cell transplantation and The progression free survival and the overall survival after the sequential infusion of Donor Lymphocyte Infusions (DLI) and Cytokine Induced Killer(CIK) cells.
To exploit the curative potential of allografting, the ultimate clinical goal is to separate GVL from GVHD. In murine preclinical models, recipients of allogeneic hematopoietic cell transplants after a preparative regimen of total lymphoid irradiation (TLI) and antithymocyte globulin (ATG) did not develop GVHD. The murine TLI/ATG study was turned into a clinical phase I protocol for patients with hematological malignancies, and a reduction of acute GVHD to < 3% was observed (Lowsky R et al, N Engl J Med). This suggests that specific immune mechanisms control GVHD and preserve GVL. The study will include patients with lympho and myeloproliferative diseases. The conditioning regimen will consist of TLI [ten 80 cGy fractions on day -11 through day -7 and on day -4 through day -1; the radiation field (four fields-two anterior and two posterior) involves all major lymphoid organs including the thymus, spleen and lymph nodes] and ATG (five i.v. doses at 1.5 mg/kg/day from day -11 through day -7). G-CSF mobilised hematopoietic cells, collected on days -1 and 0, from HLA-identical siblings or unrelated donors will be infused on day 0. Post-transplant immunosuppression will consist of oral cyclosporine (at 6.25 mg/kg/d) from day -3 and micophenolate mophetile (at 15 mg/Kg bid) from day +1. The clinical primary objective is to reduce the incidence of GVHD to < 5%, with better survival and quality of life.
The goal of this clinical research study is to learn about the safety of giving a stem cell transplant from a tissue-mismatched donor, followed by cyclophosphamide, to patients with certain types of blood disorders or blood cancers. Melphalan, thiotepa, and fludarabine will also be given before the transplant. Researchers will study the health status of these patients at 3 months after the transplant.
The purpose of this study is to determine the maximum tolerated dose and evaluate the safety of the administration of donor lymphocytes depleted of alloreactive T-cells following a stem cell transplant from a related, haploidentical donor, in patients with severe hematologic malignancies.
This study examines the effect of a small molecule inhibitor to the Sonic Hedgehog pathway on select hematologic malignancies.
The purpose of this research study is to determine the safety and efficacy of a reduced intensity conditioning regimen during a double umbilical cord blood unit transplant with one of the cord blood units modulated with ProHema.
