Filter by:For patients with hematologic malignancies undergoing allogeneic myeloablative (MA) HCT with a T cell depleted graft, the infusion of naturally occurring regulatory T cells with conventional T cells (T cell add back) in pre-defined doses and ratios will reduce the incidence of acute graft vs host disease while augmenting the graft vs leukemia effect and improving immune reconstitution.
This is a phase I single center dose escalation study with an extension at the best available dose to determine the tolerability of inducible regulatory T cells (iTregs) when given to adult patients undergoing non-myeloablative HLA-identical sibling donor peripheral blood stem cell (PBSC) transplantation for the treatment of a high risk malignancy. Up to 5 dose cohorts will be tested. Once the tolerable dose is determined for iTregs, enrollment will continue with an additional 10 patients using sirolimus/Mycophenolate mofetil (MMF) graft-versus-host disease (GVHD) prophylaxis to gain further safety information and to provide pilot data in this treatment setting.
This research study is for subjects that are receiving a bone marrow transplant. As part of the transplant subjects will receive stem cells from a donor who has agreed to donate stem cells for them. Unfortunately, it takes a long time for the immune system to recover after a bone marrow transplant. This makes it more likely for patients to develop serious infections. This study is being done to better understand how the immune system will recover after transplant. The immune system includes the cells that help fight infection. This study will help investigators understand which patients are at risk for developing infections after transplant. All children and adults receive standard vaccines (shots) during their lifetime to provide protection from many different infections. One such infection is tetanus, a bacteria that can cause life-threatening problems. After transplant patients no longer have protection from infections such as tetanus. Therefore, most patients need to receive all their vaccine (shots) again after transplant. This is usually done 1-2 years after transplant, since it may take that long for patients to have a normal immune system. However, the investigators believe that the time it will take for the patient to develop normal protection against tetanus can be shortened if both the patient and the patient's stem cell donor receive a tetanus vaccine. The goal of this study is to determine if giving a tetanus vaccine to the donor and the patient will provide the patient with enough protection (immunity) to prevent infection following bone marrow transplant.
Background: - People who have some kinds of cancer can benefit from donated bone marrow stem cells. These stem cells help produce healthy bone marrow and slow or stop the spread of abnormal cells. However, stem cells transplants do not always work. Also, they may have serious side effects that can cause illness or death. The Bone Marrow Stem Cell Transplant Program is studying methods to make stem cell transplant procedures safer and more effective. Objectives: - To test a new procedure that may improve the success and decrease the side effects of stem cell transplants. Eligibility: - Individuals 10 to 75 years of age who have a life-threatening illness that may require a stem cell transplant. - Healthy siblings who are able to provide stem cells for transplant. Design: - Participants will be screened with a medical history, physical exam, and blood and urine tests. - Donor procedures: - Stem cell donors will start by having apheresis to donate white blood cells. - Donors will receive filgrastim shots for 5 days to help move stem cells into the blood for collection. - Donors will have another round of apheresis to donate the stem cells for transplant. - Recipient procedures: - Before the transplant, recipients will have radiation twice a day for 3 days and chemotherapy for 7 days. - After the radiation and chemotherapy, recipients will receive the stem cells provided by the donor. - After the transplant, recipients will receive the white blood cells provided by the donor. - Recipients will be monitored closely for 4 months to study the success of the transplant. They will have more followup visits at least yearly thereafter. - Recipients will have a research apheresis prior to transplant and at 3 months.
CLAG-M is an active, well tolerated regimen in acute myelogenous leukemia. Each of the agents is active in Acute Lymphoblastic Leukemia (ALL) as well. The current trial will determine the efficacy of the regimen in patients with relapsed ALL.
The purpose of this study is to evaluate the multi-lineage hematopoietic chimerism for unrelated umbilical cord blood (UCB) grafts pooled from two to three cord blood units. Also to evaluate the toxicity, and antitumor responses of pooled unrelated UCB transplants.
New conditioning regimens are still needed to maximize efficacy and limit treatment-related deaths of allogeneic transplantation for advanced hematologic malignancies. Over the past several years, the investigators have evaluated several new conditioning regimens that incorporate fludarabine, a novel immunosuppressant that has limited toxicity and that has synergistic activity with alkylating agents. Recent data have suggested that fludarabine may be used in combination with standard doses of oral or IV busulfan, thus reducing the toxicity previously observed with cyclophosphamide/ busulfan regimens.
Patients will be receiving a stem cell transplant as treatment for their disease. As part of the stem cell transplant, patients will be given very strong doses of chemotherapy, which will kill all their existing stem cells. A close relative of the patient will be identified, whose stem cells are not a perfect match for the patient's, but can be used. This type of transplant is called "allogeneic", meaning that the cells are from a donor. With this type of donor who is not a perfect match, there is typically an increased risk of developing GvHD, and a longer delay in the recovery of the immune system. GvHD is a serious and sometimes fatal side-effect of stem cell transplant. GvHD occurs when the new donor cells (graft) recognize that the body tissues of the patient (host) are different from those of the donor. In this study, investigators are trying to see whether they can make special T cells in the laboratory that can be given to the patient to help their immune system recover faster. As a safety measure, we want to "program" the T cells so that if, after they have been given to the patient, they start to cause GvHD, we can destroy them ("suicide gene"). Investigators will obtain T cells from a donor, culture them in the laboratory, and then introduce the "suicide gene" which makes the cells sensitive to a specific drug called AP1903. If the specially modified T cells begin to cause GvHD, the investigators can kill the cells by administering AP1903 to the patient. We have had encouraging results in a previous study regarding the effective elimination of T cells causing GvHD, while sparing a sufficient number of T cells to fight infection and potentially cancer. More specifically, T cells made to carry a gene called iCasp9 can be killed when they encounter the drug AP1903. To get the iCasp9 gene into T cells, we insert it using a virus called a retrovirus that has been made for this study. The AP1903 that will be used to "activate" the iCasp9 is an experimental drug that has been tested in a study in normal donors with no bad side-effects. We hope we can use this drug to kill the T cells. The major purpose of this study is to find a safe and effective dose of "iCasp9" T cells that can be given to patients who receive an allogeneic stem cell transplant. Another important purpose of this study is to find out whether these special T cells can help the patient's immune system recover faster after the transplant than they would have otherwise.
This randomized pilot clinical trial studies how well giving prolonged infusion compared to standard infusion of cefepime hydrochloride works in treating patients with febrile neutropenia. Giving cefepime hydrochloride over a longer period of time may be more effective than giving cefepime hydrochloride over the standard time.
This study evaluated the safety and tolerability of using HSC835 in patients with hematological malignancies.
