Filter by:Background: - Stem cells are immature blood cells that grow in the bone marrow and produce all of the cells needed for normal blood and immunity. Stem cells can be taken from one person (donor) and given to another person (recipient) through allogeneic stem cell transplantation. Donor stem cells can then replace the recipients stem cells in the bone marrow, restoring normal blood production and immunity. Most allogeneic transplants now use stem cells collected from the donors blood in a process called peripheral blood stem cell transplantation. - Monocytopenia and mycobacterial infection (MonoMAC) is an immunodeficiency disease that is characterized by a lack of monocytes, a type of white blood cell, and an increased risk of developing mycobacteria infections that may cause tuberculosis. - Allogeneic stem cell transplantation has been used successfully to treat many kinds of immune diseases and cancers that develop in blood or immune system cells. Researchers have been studying a particular kind of stem cell transplantation that uses lower than usual doses of chemotherapy and particular combinations of drugs to improve the results of the procedure for patients with blood-related cancers and pre-cancerous conditions. Objectives: - To determine the safety and efficacy of reduced-intensity hematopoietic stem cell transplants (a particular stem cell transplantation procedure) for treating MonoMAC. Eligibility: - Patients 18-60 years of age who have MonoMAC and who have been matched with a suitable stem cell donor. Design: - Donors and recipients will undergo separate procedures as part of this protocol. - Donors: - National Institutes of Health researchers will take the donor s medical history, perform a physical exam, take blood samples, and explain the procedure. Tests will be performed to check the donors heart, lung, kidney, and liver function. - Donors will receive injections of a drug called filgrastim (G-CSF), which causes stem cells to travel from bone marrow into blood. The G-CSF shots will be given for 5 to 7 days before the collection procedure. - Donors will undergo apheresis to collect white blood cells and stem cells directly from the blood, which can be done as an outpatient procedure. Researchers may consider the alternative of directly collecting bone marrow from the donor, which will require an overnight hospital stay. - Recipients: - Recipients will receive 3 days of pre-transplant chemotherapy and radiation therapy to prepare for the transplant. For 4 days before the transplant, recipients will receive the chemotherapy drug fludarabine, followed by a single dose of radiation therapy, and will also receive the drugs tacrolimus and sirolimus to prevent the donor cells from attacking the recipient s normal tissues. - Recipients will then receive the transplant of donor stem cells and will continue to receive tacrolimus and sirolimus for 3 months after the transplant to prevent the donor cells from attacking the recipient s normal tissues. Recipients will be discharged from the hospital once their condition is stable. - Recipients will visit the NCI clinic regularly for the first 5 months after the transplant, and then less often for at least 5 years. Recipients may receive additional donor immune cells (donor lymphocyte infusion) after the transplant if the study doctors believe they are needed.
This protocol will enroll subjects with advanced hematologic malignancies who do not have a suitable related or unrelated donor to undergo a Stem Cell Transplant. In this study, subjects will undergo a Stem Cell Transplant using Cord Blood. Part of the cord blood will be used for the Stem Cell Transplant and part of the cord blood will be sent to a laboratory in order to grow the T cells (from the cord blood) and increase the activity of the cord blood T cells. The purpose of this part of the study is to see if it is safe to give study subjects activated T cells made from a small portion of their donor UCB unit immediately after the UCB transplant. Activated T cells have been used safely in stem cell transplantation studies in the past, but they have never been studied UCB transplantation.
The goal of this clinical research study is to learn if Vidaza (azacitidine) will help to control the disease in patients with AML, CMML, or MDS after an allogeneic (donor) stem cell transplant. The safety of this drug will also be studied.
Clofarabine is known to have a stronger anti-tumor effect than Fludarabine and has shown its efficacy in treating aggressive acute leukemias. In addition, evidence is that it is well-tolerated with manageable side effects especially in elderly patients. Thus, replacing Fludarabine with Clofarabine in a reduced intensity transplant regimen may provide a regimen with increased anti-tumor activity without adding significant risks of toxicity.The purpose of this study is to evaluate the efficacy and the safety of clofarabine in combination with IV busulfan and ATG as the backbone of a reduced intensity conditioning regimen for allogeneic stem cell transplantation for the treatment of patients with high-risk MDS/AML or ALL not eligible to conventional or standard myeloablative allo-SCT.
The purpose of this study is to characterize the safety and efficacy of STA-9090 (ganetespib) in subjects with hematologic malignancies.
The purpose of this study is to evaluate the OS, RFS, and TRM after HCT with low-dose total body irradiation, fludarabine, and busulfan conditioning.
The primary objectives will be to measure the safety and efficacy of allogeneic stem cell transplantation using a peripheral blood stem cell graft that has been depleted of CD45RA+ Naive T-cells. The secondary objectives will be to measure the pace of immune recovery.
The purpose of this study is to see if giving high dose chemotherapy and total body irradiation before and repeating high dose chemotherapy after a bone marrow transplant could reduce the incidence of graft rejection and disease for patients with blood cancers
The aim of this study is to investigate the efficacy of lenalidomide in high risk MDS or AML with chromosome 5 aberrations.
Revlimid® (Lenalidomide) is indicated for a type of blood cancer, myelodysplastic syndrome (MDS), at 10mg for a specific type of myelodysplastic syndrome with a genetic abnormality called "deletion 5q" in Low and Intermediate-1 (INT-1) patients (staging system according to International Prognostic Scoring System (IPSS)). The purpose of this Phase I/II study is to determine the optimal dose of Revlimid® (Lenalidomide) in MDS Low and MDS INT-1 patients without deletion 5q by slowly increasing the dose while monitoring blood counts for safety evaluation as well as observe other adverse events. Efficacy will also be observed for the phase II portion of the study.
