13 Clinical Trials for Various Conditions
The purpose of this study is to determine if budesonide prophylaxis starting day 5 after transplant reduces engraftment fever in autologous and allogeneic stem cell transplant recipients.
Engraftment Syndrome after Autologous Stem Cell Transplant: Retrospective Review in Patients with Multiple Myeloma
Background: Low-dose chemotherapy is easier for the body to tolerate than typical high-dose chemotherapy and involves a shorter period of complete immune suppression. Donor immune cells called lymphocytes, or T cells, fight residual tumor cells that might have remained in the recipients body after stem cell transplant, in what is called a graft-versus-tumor (GVT) effect. The immune-suppressing drug sirolimus appears to help prevent graft-versus-host disease (GVHD), a side effect of stem cell transplant in which donated T cells sometimes attack healthy tissues, damaging organs such as the liver, intestines and skin. Th2 cells are cells collected from the transplant donor and grown in a high concentration of sirolimus. Objectives: To determine whether stem cell transplantation using low-dose chemotherapy and sirolimus-generated Th2 cells can cause a remission of advanced kidney cancer. Eligibility: Patients between 18 and 75 years of age who have kidney cancer that has spread beyond the kidney and who have a tissue-matched sibling stem cell donor. Design: Patients undergo stem cell transplantation as follows: * Low-intensity chemotherapy with pentostatin and cyclophosphamide over a 21-day period to reduce the level of the immune system to prepare for the transplant. Pentostatin is given through a vein (intravenous (IV)) on days 1, 8 and 15; cyclophosphamide tablets are taken by mouth for 21 consecutive days. * Sirolimus tablets, taken by mouth, starting 2 days before the transplant and continuing until 60 days after the transplant. * IV infusions of stem cells and Th2 cells. Following the transplant, patients have the following procedures: * Additional Th2 cell infusions on days 14 and 45 after the transplant. * Follow-up visits at the National Institutes of Health (NIH) Clinical Center twice a week for the first 6 months after the transplant and then less frequently for at least 5 years to evaluate response to treatment and treatment side effects. Evaluations include a bone marrow aspirate and biopsy 1 month after transplant and periodic blood tests and imaging procedures (e.g., computed tomography (CT) or magnetic resonance imaging (MRI) scans).
The UCB transplant is a type of stem cell transplant used to treat cancer of the blood or lymph glands. The UCB transplant has advantages over other types of transplants such as ease of obtaining the umbilical cord blood, absence of donor risks, reduced risks of contagious infections, and the availability for immediate use. The UCB transplant is also associated with a lower incidence of graft versus host disease, or GvHD (in GvHD, the transplanted graft attacks the recipient organs).
Background: Severe aplastic anemia (SAA) and myelodysplastic syndrome (MDS) are bone marrow diseases. People with these diseases usually need a bone marrow transplant. Researchers are testing ways to make stem cell transplant safer and more effective. Objective: To test if treating people with SAA or MDS with a co-infusion of blood stem cells from a family member and cord blood stem cells from an unrelated donor is safe and effective. Eligibility: Recipients ages 4-60 with SAA or MDS Donors ages 4-75 Design: Recipients will be screened with: * Blood, lung, and heart tests * Bone marrow biopsy * CT scan Recipients will have an IV line placed into a vein in the neck. Starting 11 days before the transplant they will have several chemotherapy infusions and 1 30-minute radiation dose. Recipients will get the donor cells through the IV line. They will stay in the hospital 3-4 weeks. After discharge, they will have visits: * First 3-4 months: 1-2 times weekly * Then every 6 months for 5 years Donors will be screened with: * Physical exam * Medical history * Blood tests Donors veins will be checked for suitability for stem cell collection. They may need an IV line to be placed in a thigh vein. Donors will get Filgrastim or biosimilar (G-CSF) injections daily for 5-7 days. On the last day, they will have apheresis: Blood drawn from one arm or leg runs through a machine and into the other arm or leg. This may be repeated 2 days or 2-4 weeks later.
This is a randomized pilot study to characterize engraftment of a donor's microflora onto patients with Irritable Bowel Syndrome with diarrhea following fecal microbiota transplantation.
By doing this study, researchers hope to learn the following: * If providing hyperbaric oxygen (HBO) therapy prior to an umbilical cord blood (UBC) transplant will help to improve the homing process * The safety of HBO administration in the setting of the UBC transplant * The effects of HBO therapy on the engraftment process
The goal of this clinical research study is to learn if combining busulfan with clofarabine and fludarabine can help control the disease better than the previous standard method (using busulfan and fludarabine alone) in patients with AML or MDS. The safety of this combination therapy will also be studied.
The goal of this clinical research study is to learn if it is safe and feasible to transplant changed cord blood for patients with leukemia or lymphoma. Researchers also want to learn if this can help to control the disease. The cord blood will be changed to make use of sugar that is found in small amounts in blood cells. It plays a role in signaling where in the body the transplanted cells should go to. Adding more sugars to the cord blood cells in the laboratory is designed to help the cord blood cells find their way faster to the bone marrow. This may help your blood counts to recover faster. This process is called fucosylation. Anti-thymocyte globulin (ATG) is a protein that removes immune cells that cause damage to the body. Clofarabine is designed to interfere with the growth and development of cancer cells. Fludarabine is designed to interfere with the DNA (genetic material) of cancer cells, which may cause the cancer cells to die. This chemotherapy is also designed to block your body's ability to reject the donor's bone marrow cells. Melphalan and busulfan are designed to bind to the DNA of cells, which may cause cancer cells to die. Mycophenolate mofetil (MMF) and tacrolimus are designed to block the donor cells from growing and spreading in a way that could cause graft versus host disease (GVHD -- a condition in which transplanted tissue attacks the recipient's body). This may help to prevent GVHD. Rituximab is designed to attach to cancer cells, which may cause them to die.
The purpose of this study is to evaluate the effect of TXA127 on neutrophil and platelet counts in adult patients who have undergone a double cord blood transplant. The study will also evaluate the effect of TXA127 on chemotherapy-induced mucositis, an inflammation of the mucous membranes in the digestive tract (mouth to anus) and immune reconstitution which helps patients fight infections. For patients undergoing CBT, both neutrophil and platelet normalization and immune reconstitution can be delayed. TXA127 has shown to be well tolerated by patients and appears to induce a rapid production of neutrophils and platelets in the bloodstream as well as increase the immune system components. It has also been shown to reduce the severity of chemotherapy-induced mucositis.
The are a variety of cancerous diseases of the blood and bone marrow that can be potentially cured by bone marrow transplantation (BMT). Diseases like leukemia, lymphoma, and multiple myeloma are among the conditions that can be treated with BMT. Some patients with these diseases can be treated with medical chemotherapy alone. However, patients who relapse following chemotherapy are usually not curable with additional chemotherapy treatments. The only option known to provide a potential cure if this occurs is BMT. Allogenic transplants are cells collected from relatives of the patient. The transplant requires additional high intensity chemotherapy and radiation in order to destroy cancerous cells. In the process, many normal bone marrow cells are also destroyed. This is the reason for transplanting stem cells. The stem cells help to build new functioning bone marrow, red cells, white cells, and platelets. In addition, the immune cells from the donor are implanted into the recipient s body and help to fight off infection and kill remaining cancerous cells. Unfortunately, the powerful doses of chemotherapy and radiation therapy associated with allogenic BMT have toxic side effects and often make BMTs too dangerous to attempt in many patients. In order to reduce the complications of BMT, and make it a safer available option for patients with cancers of the blood and bone marrow, researchers have developed a new approach to the BMT. In this study researchers plan to use stem cells collected from the blood stream of patient s relatives rather than from the bone marrow (blood progenitor/stem cell transplant). In addition, researchers plan to use low doses of chemotherapy and no radiation therapy to reduce side effects. The majority of the cancer killing effect will be the responsibility of the stem cell transplant rather than the chemotherapy.
Diseases such as leukemia, lymphoma, and multiple myeloma fall into the category of blood cancers. Some of these conditions can now be cured by bone marrow transplantation (BMT). The ability of BMT to cure these conditions has been credited to the use of high doses of chemotherapy, radiation therapy, and the antileukemia effect of the transplant. Because the effectiveness of BMT relies on the use of high doses of chemotherapy and total body irradiation (TBI), it is a therapy associated with toxic side effects. These side effects are often deadly and have limited BMT for use in patients under the age of 55. In this study researchers plan to treat older patients between the ages of 55 to 75 years with blood cell transplants taken from donors who are genetically matched relatives of the patient. In order to decrease the toxic side effects associated with the transplant, researchers will not use chemoradiotherapy. Instead they plan to use intensive immunosuppressive therapy and allow the transplanted cells to take effect.
A comparative trial where all patients will receive daily doses of tacrolimus (TAC) until day +60 when tapering will begin, in the absence of graft-versus-host disease (GVHD), and discontinued by day +180. In addition patients will be randomized to methotrexate (MTX) or mycophenolate mofetil (MMF) and again, in the absence of GVHD, a tapering schedule will begin on day +240 and be completed on day +360. Doses will be adjusted to maintain blood levels.
