Filter by:In this clinical trial study, 60 patients with GvHD referred to Shahid Qazi Hospital in Tabriz, were randomly divided into 2 intervention and control groups (n= 30 in each) that received secretome and distilled water by injection, respectively. The method of blinding was triple-blinded and all the names and personal information of the patients were coded at the time of data collection and remained completely confidential.
The purpose of this Phase 1, first in human open-label study is to assess the safety and tolerability of TRX-103 in patients with hematological malignancies undergoing HLA-mismatched related or unrelated hematopoietic stem cell transplantation (HSCT). It is anticipated that up to 36 Subjects will be enrolled during a 18-24 month enrollment period. TRX-103 will be infused one time post HSCT.
This is a randomized, single-center phase 1/2a clinical trial without blinding. Regulatory T cells (Tregs) have shown potential in treating various immune-related diseases, including autoimmune disorders, transplant rejection, and inflammatory diseases. The investigators plan to recruit participants for a clinical trial to evaluate the efficacy and safety of autologous Tregs in the treatment of GVHD.
The risk of Graft-versus-host Disease(GVHD) is significantly associated with the mortality rate of patients undergoing allogeneic hematopoietic stem cell transplantation. The occurrence of GVHD increases the hospitalization rate and economic burden of patients. In order to explore better methods for controlling GVHD, we designed a clinical trial using CD25 monoclonal antibody for GVHD prevention. Our previous studies have shown that reduced-dose anti-thymocyte globulin(ATG) in the conditioning regimen can achieve the same effect as full-dose ATG. Here, we try to explore the preventive effect of CD25 antibody on acute and chronic GHVD under low-dose ATG pretreatment condition.
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) remains the only curative therapy in acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). Most of the patients requiring an allo-HSCT are above 50 years of age and are transplanted with a reduced intensity conditioning (RIC) regimen. The optimal RIC and Graft Versus Host Disease (GVHD) prophylaxis regimen allowing a good control of the disease while preventing GVHD remains to be determined for elderly patients. A phase III trial comparing the conventional RIC fludarabine-busulfan 2 days to fludarabine-treosulfan demonstrated an advantage for the flu-treosulfan arm in terms of event free survival (EFS), that should therefore be considered as the new standard of RIC regimen for AML and MDS. GVHD prevention has a crucial role in post-transplant outcomes by potentially interfering with the graft-versus-leukemia (GVL) effect and immune reconstitution. Anti-thymocyte globulins (ATG) are recommended to reduce the risk of acute and chronic GVHD in transplants performed with matched unrelated donors. However, the optimal type of ATG between the 2 approved brands (ATG-thymoglobulin and ATLG-grafalon) displaying distinct characteristics and the optimal dose of ATG are still unknown. In a retrospective study of patients transplanted mainly with RIC with matched related and unrelated donors for haematological malignancies, we observed that Anti-T lymphocyte globulin (ATLG) was associated with a reduction of grade II-IV acute GVHD in comparison to ATG without increasing the incidence of relapse. In this phase III randomised study, we propose to compare GVHD prevention with ATG versus ATLG in AML and MDS patients above 50 years of age transplanted with a matched unrelated donor following a fludarabine-treosulfan RIC, with the hypothesis that ATLG would better control GVHD in this population of patients thus limiting the risk of morbidity and mortality of the procedure.
The goal of this observation study is to test in patients undergoing allogeneic hemopoietic stem-cell transplantation (allo-HSCT). The main question it aims to answer is: • Effect of MAGIC algorithm probability guided preemption of aGVHD with ruxolitinib on prevention of severe aGVHD. Participants will take ruxolitinib with the dose of 5mg bid for 28 days. If no signs of aGvHD, the dose of ruxolitinib is gradually tapered within the following 16 days. Researchers will compare patients who don't receive preemption of aGVHD with ruxolitinib to see if there is an improvement in severe aGVHD.
Post-transplantation cyclophosphamide (PTCY) is considered as major graft versus host disease (GVHD) prophylaxis. In our previous study, the investigators demonstrated that the standard dose PTCY of 50mg/kg with tacrolimus and post-engrafted low-dose anti-thymoglobulin (ATG) achieved low incidence of acute GVHD. More recently, it has been shown that reduced dose of PTCY of 40mg/kg is considered with similar efficacy as GVHD prophylaxis, In this study, a multi-center randomized comparison is planned to evaluate the clinical outcome of GVHD prophylaxis of PTCy 40 versus 50.
The purpose of this study is to find out whether photobiomodulation/PBM therapy using the Thor LX2.3 therapy system is a safe and effective treatment for oral Graft-Versus-Host Disease/GVHD.
Interleukin 2 (IL-2) is a critical cytokine for the survival and function of regulatory T cells (LTreg). This cytokine has a dual role in the immune system. IL-2 stimulates immune responses by acting on the intermediate affinity IL-2R receptor, IL-2Rβγ, expressed by conventional T cells (LTconv) during activation, but also contributes to the inhibition of immune responses via LTreg that express the high affinity receptor IL-2Rαβγ. This difference in IL-2 receptor affinity for IL-2 has led to the development of low-dose IL-2 therapy to stimulate LTreg and improve control of excessive inflammation in autoimmune (AID), inflammatory or alloimmune diseases Low-dose IL-2 therapy is being studied in several of these diseases such as systemic lupus erythematosus, type 1 diabetes, alopecia, HCV (hepatitis C virus)-induced vasculitis, atopic dermatitis and chronic allo-transplantation-related graft-versus-host disease (GVHD). Some of these studies have shown an increase in LTreg numbers and an improvement in certain clinical signs. To improve LTreg targeting in autoimmune diseases, inflammatory diseases or GVHD, mutated IL-2s (muteins) have been developed with selective LTreg agonist properties. These IL-2 muteins are linked to an Fc fragment to increase their half-life. Two IL-2 variants (IL-2Vs)-Fc preferentially stimulate STAT5 phosphorylation in LTregs compared to conventional FoxP3- (LTconv) CD4+ or CD8+ T cells
The aim of this trial is to assess safety and efficacy of apraglutide in subjects with steroid refractory gastrointestinal acute graft versus host disease (aGVHD).
