Filter by:This study is to establish the safety, determine if there is an improvement in steroid refractory acute graft-vs-host disease (aGvHD) compared to historical cohorts, and determine the changes of aGvHD-associated T-cell clones in patients with steroid-refractory aGVHD following allogeneic hematopoietic cell transplantation administered AbGn-168H once weekly for 4 weeks.
This phase II trial studies how well methylprednisolone sodium succinate works in treating patients with graft-versus-host disease (GVHD) of the gastrointestinal tract that has begun within 100 days of transplant (acute GVHD). Corticosteroids are a type of drug that reduces inflammation. Giving corticosteroid drugs, such as methylprednisolone sodium succinate, directly into the arteries of the gastrointestinal tract may help treat inflammation caused by GVHD. Giving methylprednisolone sodium succinate in addition to standard treatments may be more effective in treating GVHD.
Graft-versus-host-disease (GVHD) is a major obstacle to successful allogeneic hematopoietic cell transplantation (alloHCT). Cannabidiol (CBD), a non-psychotropic ingredient of Cannabis sativa possesses potent anti-inflammatory and immunosuppressive properties. In a recent phase 2 study, CBD has been shown to be safe and reduced significantly the incidence of acute GVHD compared to control patients with a hazard ratio of 0.3. Based on these results the investigators propose a phase 2 study to explore the efficacy of oral CBD in the treatment of severe (grades III/IV) acute GVHD, a pathology with a dismal prognosis.
Subjects in this study have had an allogeneic (blood or marrow cells from another person) blood or marrow transplant to treat leukemia, lymphoma or other cancer of the blood, and have now developed Graft Versus Host Disease (GVHD) that is not responding to standard treatment. GVHD is when the graft (transplanted bone marrow or blood) attacks the recipient's body. GVHD occurs early after transplant (acute) and/or sometimes months after transplant (chronic). Both forms can be life threatening; chronic GVHD can be a lifelong disabling condition. Mesenchymal stromal cells (MSCs) exist in tissues throughout the body. One place they are found is in the bone marrow and from here they can be obtained by needle aspiration, the same way bone marrow samples are obtained to test for leukemia. This study uses autologous MSCs obtained from the recipient with acute and/or chronic GVHD, which have a lower chance of being rejected. These MSCs may promote tolerance, helping the donor immune cells accept the recipient's body. This trial is being conducted as a step toward testing the long-term hypothesis that freshly cultured autologous MSC grown in platelet lysate-containing medium will modulate donor T-cell immune responses and reduce GVHD in allo-HSCT recipients. As a phase I dose escalation trial of autologous MSC in patients with acute and chronic GVHD, the main aim is to evaluate the safety of this therapy and its effects on GVHD biomarkers and T-cell phenotype
The objectives of this trial were to evaluate the safety, tolerability, pharmacokinetics/pharmacodynamics (PK/PD) and efficacy of intravenous (IV) ALXN1007 in participants with acute graft-versus-host disease (GVHD) of the lower gastrointestinal (GI) tract.
The purpose of this study is to compare the efficacy of CD25 monoclonal antibody and calcineurin inhibitors with or without mesenchymal stem cells (MSCs) in treating patients with steroid-resistant acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation.
The specific objectives of this study are: Primary: 1)To determine the relationship between cyclosporine AUC achieved prior to engraftment and severe aGVHD (grade III and IV) Secondary: 1. To determine the relationship between individual concentration-time points achieved prior to engraftment and severe aGVHD (grade III and IV) 2. To validate the previously developed LSS to determine cyclosporine AUC after IV administration at steady state and 3. To describe the relationship between cyclosporine AUC and individual concentration-time points achieved prior to engraftment and other HSCT outcomes (clinically significant aGVHD (grade II to IV), hypertension, engraftment failure, relapse
This research trial is designed to study the safety and effectiveness of combining the study drug, Natalizumab (Tysabri®) with the standard treatment, the use of steroids, as a new treatment for acute graft versus host disease (acute GVHD). GVHD is the most common serious complication, after bone marrow transplant. GVHD occurs when the donor cells (the graft), treat the recipient's body as "foreign" and attack the cells in the recipient's body. During this immune system response, donor cells damage body tissues, such as the skin, liver, stomach, and/or intestines. Acute GVHD can be severe and if severe, potentially fatal to the transplant recipient. Acute GVHD usually happens within the first several months after transplant. The goal of this research is to develop a safer and more effective treatment for acute GVHD, and particularly for acute GVHD that affects the gastrointestinal (or GI) tract, with the ultimate goal being safer and more effective transplant therapies for blood cancers such as leukemia, lymphoma, and multiple myeloma.
Acute Graft-versus-host disease(aGVDH) after allogeneic hematopoietic stem cell transplantation is one of the meaningful issues in aspect of patient's recovery and survival. in recent years, the understanding of the pathology of GVHD is much important to prevent or treat aGVHD. additionally, (oral) mucositis is one of the problems in patients with high dose chemotherapy, and mucositis by high-dose chemotherapy is related to HMGB-1 as proinflamtory cytokines. HMGB1 is a nuclear protein acts as a transcription factor, but, if it was released to the outside of cells by damaged cell or necrotic tissues, it works as cytokines for promoter of inflammation and cancers. at this point, there are no reported articles about correlation of HMGB1 and aGVHD in human. recently, we have seen excessive secretion of serum HMGB1 in mouse model, then base on this results, we will check correlation of HMGB1 and aGVHD/ oral mucositis in human.
The immune system has offensive and defensive capacities. In bone marrow transplantation, offensive cells in the donor grafts may attack host's organs, leading to a complication known as Graft versus Host Disease (GVDH). At present, patients receive steroid treatment to combat this tricky situation. Nevertheless, some patients do not respond to this therapy. Recently, it has been shown that immune system cells having defensive capacities can help in preventing the occurrence of a GVDH. This study aims to evaluate if these protective cells together with a non-standard immunosuppressor can improve the clinical condition and suppress the activity of the offensive cells in the graft.
