The aim of the research in this study is to make participants' transplant safer by reducing the risk of developing GVHD and GVHD-related complications by giving participants a dose of the drug tocilizumab in addition to the standard approach for GVHD prevention. Tocilizumab reduces the risk of inflammation by blocking the effect of Interleukin-6, a protein that exists in high levels in the blood when there is inflammation. Participants who receive stem cell transplants have high levels of this protein in their blood early after transplant. Therefore, the goal of this study is to reduce the risk of inflammation after transplant with the addition of Tocilizumab. This could decrease the risk of developing GVHD and GVHD-associated complications.
NCT01758042
The main purpose of this study is to examine the outcome of a combined bone marrow and kidney transplant from a partially matched related (haploidentical or "haplo") donor. This is a pilot study, you are being asked to participate because you have a blood disorder and kidney disease. The aim of the combined transplant is to treat both your underlying blood disorder and kidney disease. We expect to have about 10 people participate in this study. Additionally, because the same person who is donating the kidney will also be donating the bone marrow, there may be a smaller chance of kidney rejection and less need for long-term use of anti-rejection drugs. Traditionally, very strong cancer treatment drugs (chemotherapy) and radiation are used to prepare a subject's body for bone marrow transplant. This is associated with a high risk for serious complications, even in subjects without kidney disease. This therapy can be toxic to the liver, lungs, mucous membranes, and intestines. Additionally, it is believed that standard therapy may be associated with a higher risk of a complication called graft versus host disease (GVHD) where the new donor cells attack the recipient's normal body. Recently, less intense chemotherapy and radiation regimens have been employed (these are called reduced intensity regimens) which cause less injury and GVHD to patients, and thus, have allowed older and less healthy patients to undergo bone marrow transplant. In this study, a reduced intensity regimen of chemotherapy and radiation will be used with the intent of producing fewer toxicities than standard therapy. Typical therapy following a standard kidney transplant includes multiple lifelong medications that aim to prevent the recipient's body from attacking or rejecting the donated kidney. These are called immunosuppressant drugs and they work by "quieting" the recipient's immune system to allow the donated kidney to function properly. One goal in our study is to decrease the duration you will need to be on immunosuppressant drugs following your kidney transplant as the bone marrow transplant will provide you with the donor's immune system which should not attack the donor kidney.

The classic Ph-negative myeloproliferative neoplasms (MPN) are a group of clonal hematopoietic disorders caused by a dysregulated JAK/STAT signal transduction because of acquired somatic mutations of JAK2, CALR or MPL genes. Chronic inflammation may predispose to MPN development. SARS-CoV-2 infection displays extreme interindividual clinical variability, ranging from asymptomatic infection to life-threatening coronavirus disease (COVID-19). Age is a major risk factor for severe disease. Male sex and medical comorbidities have minor impact. It was demonstrated that at least 3.5% of patients with life-threatening COVID-19 have monogenic inborn errors of TLR3- or TLR7-dependent type I interferons (IFN-I) immunity. It has also been described that at least 15% of patients with life-threatening COVID-19 have neutralizing autoantibodies (AAbs) against IFN-I, that precede SARS-CoV-2 infection. As regard MPN, COVID-19 is associated with a mortality as high as 33%. Patients with MF had the highest mortality (48%), while patients with ET had the greatest risk of venous thromboembolism (16.7%). In this prospective study, we want to search for AAbs against IFN-I in a cohort of MPN patients to evaluate their prevalence in the MPN population and to look for clinical correlations, including COVID-19 severity.
NCT07204392
The classic Ph-negative myeloproliferative neoplasms (MPN) are a group of clonal hematopoietic disorders caused by a dysregulated JAK/STAT signal transduction because of acquired somatic mutations of JAK2, CALR or MPL genes. They are sporadic diseases but there are several lines of evidence that support the role of germline factors in the pathogenesis of MPN: the existence of familial clustering, the presence of more than one clone in some patients, the known existence of common polymorphisms that cause predisposition to MPN. In this study, we would like to define the germline predisposition to MPN.
NCT05969821
Ambispective, national, multicenter observational cohort study aimed at characterizing the satellite dysimmune manifestations of clonal hematopoiesis, including Vexas (Vacuoles, E1 enzyme, X-linked, Autoinflammatory and Somatic) syndrome.
NCT06727383
Recent studies demonstrated the safety and efficacy of allogeneic and autologous infusion of NK cells as adoptive immunotherapy in malignant hematological diseases and solid tumors.NK cells are innate immunity effectors with antitumor activity regulated by a wide variety of receptors located on their cell surface, with both activating and inhibiting roles.Receptors with an inhibitory role include receptors of the KIRs family (Killer Immunoglobulin like Receptors) and receptors of the CD94 / NKG2A complex and are capable of recognizing molecules of Human Leukocyte Antigen class I (HLA-I). Receptors of the KIRs family are members of the immunoglobulin superfamily and are encoded by highly polymorphic genes located on chromosome 19q13.4 in a region known as a leukocyte receptor cluster (LCR). The predominant ligand for KIRs receptors is HLA-C, but other studies show that HLA-A and HLA-B are also involved. Receptors with an activating role, on the other hand, such as NCRs (Natural Cytotoxic receptors), are specific to NK cells, while other epitopes such as CD 56 are also present on other populations of T lymphocytes. This receptor condition allows, in patients suffering from haemopathy and undergoing transplantation allogeneic stem cell, an alloreactivity induced by the mismatch between the donor's KIRs and their ligands on recipient target cells and, therefore, the role of NK cells as allogeneic effectors. The engraftment of NK cells has been shown to be correlated with a lower risk of disease recurrence, therefore the therapeutic infusion of NK cells from donors could allow, with benefit, the acquisition of fully functional NK cells in the recipient.
NCT05553873
This study aims to observe inflammatory biomarkers and their trend over the history of the disease in patients suffering from MPN Ph negative; it also wants to identify any correlations between the aforementioned biomarkers and disease outcomes, considering first of all the occurrence of thrombo-haemorrhagic events and the evolution in the accelerated / blast phase of the disease, shedding light on new tools that can potentially guarantee a prompt and better risk stratification
NCT00611351
RATIONALE: Giving chemotherapy before a donor bone marrow transplant or peripheral stem cell transplant helps stop the growth of cancer cells and helps stop the patient's immune system from rejecting the donor's stem cells. When certain stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving tacrolimus and mycophenolate mofetil after the transplant may stop this from happening. PURPOSE: This phase II trial is studying how well giving busulfan together with cyclophosphamide and antithymocyte globulin followed by donor stem cell transplant works in treating patients with hematologic cancer.
NCT05825326
The goal of this observational study is to evaluate the epidemiological and clinical-pathological features of Philadelphia-negative myeloproliferative neoplasms through data from medical records
NCT00075816
The study is designed as a Phase III, randomized, open label, multicenter, prospective, comparative trial of granulocyte colony stimulating factor (G-CSF)-mobilized peripheral blood stem cells (PBSC) versus marrow from unrelated donors for transplantation in patients with hematologic malignancies. Recipients will be stratified by transplant center and disease risk and will be randomized to either the PBSC or marrow arm in a 1:1 ratio.
NCT00054236
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Umbilical cord blood transplantation may be able to replace cells destroyed by chemotherapy. PURPOSE: Phase I trial to study the effectiveness of combination chemotherapy followed by umbilical cord blood transplantation in treating patients who have hematologic cancer or severe aplastic anemia.
NCT00274820
RATIONALE: Drugs used in chemotherapy, such as arsenic trioxide and dexamethasone, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Sometimes when chemotherapy is given, it does not stop the growth of cancer cells. The cancer is said to be resistant to chemotherapy. Giving ascorbic acid may reduce drug resistance and allow the cancer cells to be killed. Thalidomide may stop the growth of cancer cells by blocking blood flow to the cancer. Giving arsenic trioxide together with ascorbic acid, dexamethasone, and thalidomide may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving arsenic trioxide together with ascorbic acid, dexamethasone, and thalidomide works in treating patients with chronic idiopathic myelofibrosis or myelodysplastic or myeloproliferative disorders.
NCT00036790
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Motexafin gadolinium may increase the effectiveness of doxorubicin by making tumor cells more sensitive to the drug. PURPOSE: Phase I trial to study the effectiveness of combining motexafin gadolinium with doxorubicin in treating patients who have recurrent or metastatic cancer.
NCT00044954
RATIONALE: Radiation therapy uses high-energy x-rays to damage cancer cells. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with donor peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combining total-body irradiation with fludarabine and donor peripheral stem cell transplantation in treating patients who have hematologic cancer.
NCT01875237
The goal of this clinical research study is to learn if giving genetically changed immune cells, called T-cells, after chemotherapy will improve the response to a stem cell transplant. The safety of this treatment will also be studied. The process of changing the DNA (the genetic material in cells) of these T-cells is called "gene transfer." Researchers want to learn if these genetically-changed T-cells are effective in attacking cancer cells in patients with leukemia, MDS, lymphoma, Hodgkin disease, or MM, after they have received an allogeneic stem cell transplant. The chemotherapy you will be given on study is fludarabine, melphalan, and alemtuzumab. These drugs are designed to stop the growth 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 stem cells. Researchers also want to learn if giving AP1903 will help the symptoms of graft-versus-host disease (GvHD) that may occur after the T-cell infusion. GvHD occurs when donor cells attack the cells of the person receiving the stem cell transplant.
NCT00530218
RATIONALE: Antiviral drugs, such as ganciclovir, act against viruses. Giving ganciclovir by infusion and then by mouth may be effective treatment for cytomegalovirus that has become active after donor bone marrow transplant. PURPOSE: This phase II trial is studying how well giving ganciclovir by infusion and by mouth works in treating patients with cytomegalovirus after donor bone marrow transplant.
NCT00290628
RATIONALE: Giving chemotherapy and total-body irradiation before a donor umbilical cord blood transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the stem cells from a related or unrelated donor, that do not exactly match the patient's blood, are infused into the patient they may help the patient's bone marrow to make stem cells, red blood cells, white blood cells, and platelets. PURPOSE: This clinical trial is studying how well donor umbilical cord blood transplant works in treating patients with hematologic cancer.
NCT00555048
RATIONALE: Monoclonal antibodies, such as alemtuzumab, can find cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Giving chemotherapy drugs, such as busulfan and cyclophosphamide, before a donor stem cell transplant helps stop the growth of cancer cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving tacrolimus and methotrexate after the transplant may stop this from happening. PURPOSE: This phase I/II trial is studying the best dose of alemtuzumab when given together with busulfan and cyclophosphamide followed by a donor stem cell transplant and to see how well it works in treating patients with hematologic cancer.
NCT00003961
RATIONALE: Colony-stimulating factors, such as sargramostim, may increase the number of immune cells found in bone marrow or peripheral blood. PURPOSE: Phase II trial to study the effectiveness of sargramostim after bone marrow transplantation in treating patients who have myelodysplastic syndrome.
NCT00592046
This study uses a new investigational (not yet approved by the FDA for widespread use) drug called ZIO-101, an organic arsenical. You must be diagnosed to have relapsed/refractory leukemia or lymphoma (blood cancer) and have tried other standard therapies. This study is designed to determine whether ZIO-101 may be given safely. The study will also test whether ZIO-101 helps to treat blood cancer. We anticipate that approximately 22 to 35 patients will take part in this study. Arsenic has been used as a medicinal agent for centuries in many different cultures. Most recently in the United States, an inorganic arsenic compound was approved by the FDA for the treatment of patients with relapsed acute promyelocytic leukemia (APL). However, use of inorganic arsenic is limited by a narrow range of activity and systemic toxicity, most notably of the cardiac system. ZIO-101 is an organic arsenic derivative. In vitro testing in both the National Cancer Institute (NCI) cancer cell panel and in vivo testing in a leukemia animal model demonstrated substantial activity of SGLU against hematologic cancers. In vitro testing of SGLU using the NCI human cancer cell panel also detected activity against lung, colon and brain cancers, melanoma, and ovary and kidney cancers. Moderate activity was seen against breast and prostate cancers cells. Data suggest that organic arsenic generates reactive oxygen species in the cells to induce apoptosis and cell cycle arrest.
