Filter by:To observe the effect of stem cell infusion on the development of acute graft-versus-host disease (aGVHD) in patients with malignant hematologic diseases after allogeneic peripheral blood hematopoietic stem cell transplantation (allo-PBSCT)
Allogeneic Hematopoietic Stem Cell Transplantation (alloHSCT) represents the only curative option for many patients diagnosed with various hematologic neoplasms. Procedure-related morbidity and mortality pose challenges to long-term outcomes and quality of life, especially among patients who develop chronic graft-versus-host disease (cGVHD). There is a gap in healthcare that comprehensively addresses the specific needs of these patients. Physical therapy as an adjuvant treatment, through therapeutic exercise involving muscle strength and cardiorespiratory endurance, has shown positive influences on health markers and serves as a strong medical ally in similar profiles. Although these strategies could be reproducible and potentially beneficial for cGVHD patients, research has been limited to date, with the role of physical therapy possibly underutilized in this field. Justification: Unaddressed medical gap with no rigorously scientific responses specific to cGVHD. Objectives: This project aims to conduct the first randomized clinical trial from a physical therapy perspective as an adjuvant treatment for patients undergoing alloHSCT diagnosed with cGVHD.
This phase II trial tests how well ibrutinib works in preventing chronic graft-versus-host disease (GVHD) in patients undergoing donor (allogeneic) hematopoietic cell transplantation (HCT). An allogeneic hematopoietic cell transplantation (allo-HCT) is a treatment in which a person receives blood-forming stem cells (cells from which all blood cells develop) from a genetically similar, but not identical donor. When healthy stem cells from a donor are infused into a patient, they may help the patient's bone marrow make more healthy cells and platelets. However, sometimes the transplanted cells from a donor can attack the body's normal cells (called GVHD). Giving ibrutinib after the transplant may stop that from happening. Ibrutinib is in a class of medications called kinase inhibitors. It works by blocking a protein in the blood called Bruton's tyrosine kinase (BTK). By blocking BTK, ibrutinib inhibits certain immune cells that play a role in cGVHD. Giving ibrutinib after an allo-HCT may prevent the development of chronic GVHD.
This study will be conducted to determine the clinical efficacy of axatilimab in Japanese participants with chronic graft-versus-host disease (cGVHD).
Graft-versus-host disease (GVHD) is a major complication of allogeneic hematopoietic stem cell transplantation (allo-CSH). Recently, in the context of semi-identical (=haploidentical) HLA donors, but also of compatible HLA donors, the use of cyclophosphamide (CY) administered in high doses at early post-transplant (PT) (=PTCY) (Days +3 and +4 or +5) has shown excellent control of acute and chronic GVH, even enabling the discontinuation of other immunosuppressive drugs administered after allo-CSH (ciclosporin, mycophenolate mofetyl (MMF) or Cellcept). This step has already been taken in the context of allo-CSH with myeloablative conditioning (MAC), which is a minoritary conditioning in adults. However, in the context of allo-CSH with reduced-intensity conditioning (RIC), which predominates in adults, this strategy seems insufficient to prevent the risk of GVHD. The idea of reducing the use of immunosuppressants in the context of RIC/HLA-compatible transplants seems, however, still relevant, in order to reduce their adverse effects, improve patients' quality of life and enhance the reconstitution of the post-transplant immune system.
The goal of this clinical trial is to test the assess the diagnostic effectiveness of endocytoscopy in patients with underlying UGI aGvHD. The main question it aims to answer is: the effectiveness of ECS for diagnosing UGI aGvHD. Participants will undergo endoscopy, endocytoscopic evaluation and biopsy simultaneously. If there is a comparison group: Researchers will compare endoscopic, endocytoscopic and pathologic findings of these patients.
Graft versus Host Disease (GVHD) is frequent after allogeneic stem cell transplantation (alloSCT). GVHD occurs following 2 patterns : acute GVHD (aGVHD) or chronic GVHD (cGVHD). The latter occurs in nearly 50% of patients and its pathogenesis remains poorly understood. Previous translational studies have delineated biological immune dysregulation involved in cGVHD and facilitated the development of new drug and therapeutic strategies. New aspects of T and B cells collaboration in the context of cGVHD using blood description of a key player called TFH, classicaly involved in germinal center reaction, were previously uncovered (Forcade et al, Blood 2016). Previous studies in the context of auto-immune inflammation (lupus nephritis) or organ transplant rejection, suggested that target tissue could contain accessory lymphoid structures (TLS). The description of such structures in cGVHD target tissue would give the opportunity to directly analyze immune key player involved the pathogenesis of cGVHD.
The aim of this study is to evaluate the efficacy and safety of anti-thymocyte globulin combined with PTCy (post-HSCT cyclophosphamide, PTCy) in preventing graft-versus-host disease (GVHD) in allo-HSCT patients after anti-PD-1(anti-programmed cell death protein 1) antibody treatment. In this study, patients with hematological malignancies who needed to receive allo-HSCT after PD-1 antibody treatment were selected as the research subjects. Fludarabine and Busulfan was used as the conditioning regimen, and the dose of ATG (anti-thymocyte globulin, ATG) combined with PTCy was used as the GVHD prevention regimen. The aim of this study is to reduce the incidence of Regimen-Related Toxicity and GVHD without affecting engraftment and relapse, thereby reducing non-relapse mortality and further improving the survival of patients.
This is an open-label phase I study of fostamatinib in combination with ruxolitinib for the treatment of chronic GvHD with a suboptimal response to corticosteroids. The primary objective is to identify a minimum safe and biologically effective dose of fostamatinib when combined with standard of care ruxolitinib for the treatment of steroid refractory and steroid dependent cGVHD. The secondary objective is to estimate the efficacy of the combination of ruxolitinib and fostamatinib for the treatment of steroid refractory and steroid dependent cGVHD. The target enrollment is 24-30 subjects. The study will begin with an initial dose escalation cohort employing a modified 3+3 design to investigate up to three doses of fostamatinib. Using safety, efficacy, pharmacodynamic (PD), and pharmacokinetic data (PK), an interim assessment will be performed to determine two candidate doses of the biologically optimal dose to investigate further. A safety expansion cohort will be opened to backfill these two candidate doses up to a total 12 patients per dose, including those in the dose escalation cohort who received the candidate doses. Patients will then be randomized to one of these two candidate doses in te expansion. A final analysis of safety, efficacy, and PK/PD data in patients who received the two candidate doses will be conducted to determine a minimum safety and biologically effective dose, which will be the recommended phase II dose (RP2D). The primary hypothesis is that Fostamatinib combined with ruxolitinib is a safe therapy for and has synergistic activity in cGvHD. The recommended phase II dose will be determined by the study investigators in collaboration with the sponsors. The decision to select the recommended phase II dose will occur only after all patients in the part 1 have completed at least 28 days of therapy. The decision will be based on the valuation of all relevant, available data, and not solely on dose-limiting toxicities.
The investigators aimed to reveal the relationship between serum markers of pyroptosis, GVHD biomarkers and endothelial damage markers in patients who were planned for allogeneic stem cell transplantation for AML and developed GVHD during follow-up. Secondary outcomes of the study were to demonstrate the role of pyroptosis in the pathophysiology of GVHD and transplantation-associated endothelial injury using serum plasma samples; the efficacy of GVHD biomarkers used to demonstrate organ-specific involvement; and the efficacy of GVHD biomarkers and endothelial injury markers in predicting the development of GVHD, transplantation-associated endothelial injury and non-relapse mortality.
