NCT05579639
Bloodstream infections (BSI) caused by bacteria translocating across injured oral mucosa are a significant cause of morbidity and mortality in patients undergoing stem cell transplantation (SCT). Unfortunately, there are currently no known strategies to prevent these BSI in this vulnerable population. The investigators will conduct a randomized, double-blind, placebo-controlled trial at three institutions to evaluate the effectiveness of twice daily intraoral xylitol-wipe application on reducing BSI in pediatric SCT patients.
NCT03286530
This research study is studying a drug that may help decrease the chances of relapse after Allogeneic Stem Cell transplantation for Acute Myeloid Leukemia. The name of the study drug involved in this study is: • Ruxolitinib
NCT06297629
To learn if ASTX727 given alone or in combination with donor lymphocyte infusion (DLI) can help to control certain types of hematological neoplasms (blood-based cancers) after a stem cell transplant.
NCT06453460
This is a phase 2, prospective cohort clinical trial evaluating the utilization of CMV T Cell Immunity Panel (CMV-TCIP) assay to guide the duration of primary CMV prophylaxis in CMV-seropositive recipients of allogeneic stem cell transplant or recipients receiving a stem cell graft from a CMV serology positive donor.
NCT05447663
The purpose of this study was to confirm a safe dose and schedule as well as the preliminary efficacy of siremadlin alone, and in combination with donor lymphocyte infusion (DLI), in adult participants with Acute Myeloid Leukemia (AML) who were in remission following allogeneic stem cell transplantation (allo-SCT) but were at high risk for relapse based on the presence of pre-transplant risk factors.
NCT03982992
This phase 2 study is designed to evaluate the safety, tolerability and efficacy of allogeneic donor lymphocyte infusions (DLI) combined with the bispecific T cell engager blinatumomab in B-precursor ALL patients who have mixed chimerism (MC) or are MRD-positive after allogeneic SCT and are refractory to at least one MRD- or MC-targeted therapy (i.e. blinatumomab, DLI, tyrosine kinase inhibitors or other agents).
NCT03882203
For patients with refractory acute leukemia, allogeneic stem cell transplantation is the only curative therapy. Only 20% of patients may achieve long-term survival mostly due to relapse or nor-relapse mortality (NRM). In previous study, we demonstrated that intensive leukemia debulking chemotherapy FLAG-IDA sequential with Flu-BU conditioning is feasible with \~40% long-term survival. In the study, we further modified the chemotherapy with cladribine replacing fludarabine aiming a more potent anti-leukemia effect. Meanwhile, we reduce the dose of busulfan for patients with poor performance status and age over 45 aim to reduce the NRM. All patients will also receive post-transplantation maintenance therapy with low-dose decitabine to prevent relapse.
NCT04920474
The primary purpose of the Research Sample Repository is to make blood samples available for research studies related to histocompatibility and hematopoietic cell transplantation (HCT) or other cellular therapy. Representatives of participating centers and investigators or research groups may request access to research samples contained in the Research Sample Repository for the purpose of conducting research including: * investigating molecular explanations for histocompatibility or clinical outcomes through analysis of genomic, epigenetic, or other biomolecular data * evaluating the factors that affect transplant or cellular therapy outcome * studying the distribution of HLA tissue types in different populations * studying the success of transplantation, cellular therapies or supportive care in the management of marrow toxic injuries * performing de-linked (anonymous) research
NCT03233659
Graft versus Host disease ( GVHD) is one of the major complications of Allogeneic Stem Cell Transplantation. Acute GVHD develops early ( within 2to 3 months) after transplantation and is the leading cause of death of transplanted patients. The pathogenesis of Chronic GVHD is still little known. Chronic GVHD is caused by donor T lymphocytes, but we have no precise knowledge on the participation of specific subsets of immune system cells to chronic GVHD. In general, chronic GVHD is associated with an increase in the number of T effector lymphocytes, both helper type 2 and cytotoxic. Recently, also antigen presenting cells (APCs) have been implicated in pathogenesis of chronic GVHD in studies performed on animal models. T lymphocyte responses that characterize chronic GVHD require that recipient antigens are submitted by APCs which originate from the donor's HSC ( Hematopoietic Stem Cells) APCs are heterogeneous population that includes dendritic cells (DCs) ,monocytes, activated B lymphocytes and CD34+ cell subpopulations. These cells can be identified by cytometry. The data about APCs role in chronic GVHD are preliminary and often discordant. Seemingly, there isn't correlation between circulating APCs number and risk of cGVHD. However, recent data of our group show that patients with cGVHD could have higher number of monocytes in bone marrow than transplanted patients without cGVHD. The aim of study is to measure the number of circulating immune cells in the PB (peripherical blood) before and after Allogeneic Hematopoietic Stem Cell Transplantation by flow cytometry.
NCT02227641
In patients after allogeneic stem cell transplantation reactivation of latent herpesviruses such as Cytomegalovirus (CMV) and Epstein Barr Virus (EBV) is a frequent and life threatening complication requiring antiviral treatment. The underlying problem is a severe suppression of the donors immune system after transplantation into the patient. Herpesviruses such as CMV and EBV persist after primary infection life long in the host and therefore require constant immunological control. This control is largely provided by the T-cell compartment of the immune system. After allogeneic stem cell transplantation the T-cell compartment requires a long time for its reconstitution since only a small fraction of the donor T-cells are transplanted. During this time Herpesviruses can reoccur due to the lack of effective T-cell control. This study therefore aims at reconstituting the T-cell compartment with CMV and EBV specific T-cells at an early time point after allogeneic stem cell transplantation. It is mainly a phase I study to demonstrate that these in vitro generated T-cells can be applied safely in this patient population. The study also aims at demonstrating the efficacy of CMV/EBV specific T-cells by monitoring viral reactivation and use of antiviral drugs. The hypothesis is, that CMV/EBV specific T-cell can be applied safely and do not result in graft versus host disease and that they successfully prevent reactivation of CMV and EBV after adoptive transfer in patients after allogeneic stem cell transplantation.
NCT01326273
The investigators will assess whether the infusion of autologous CMV-specific T-cells at the time of CMV reactivation posttransplant will prevent worsening of CMV virus reactivation posttransplant to a level that warrants therapy with antiviral drugs (objectively assessed by looking at CMV virus copy number).
NCT00737113
The primary objective of this study is to define the safety and efficacy of recombinant human growth hormone (rh-GH, Genotropin) in a patients undergoing allogeneic transplantation.
NCT02069639
Relapsed and refractory Hodgkin's lymphoma (HL) patients may experience long-term survival after allogeneic transplant (alloSCT), but disease recurrence represents the main cause of treatment failure. PET (positron-emission tomography) -positive patients after alloSCT have a dismal outcome. Serum TARC (thymus and activation-regulated chemokine) is produced by Reed-Sternberg cells and may be a marker of disease. Our study was aimed at assessing whether TARC levels after alloSCT were correlated to disease status and whether TARC monitoring could increase the ability to predict relapse.

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.

The purpose of this study is to determine whether inhaled Budesonide/formoterol is effective in the treatment of bronchiolitis obliterans after allogeneic stem cell transplantation.
