Filter by:Phase III randomized double-blinded trial designed to compare the efficacy of the addition of MTX to current standard acute GVHD first-line treatment with corticosteroids. The protocol will use a novel endpoint for benchmarking interventions based on a composite primary endpoint of GVHD-free and corticosteroids-free survival. The primary endpoint of the trial will be the assessment of a composite endpoint of graft-versus-host disease-free and corticosteroids-free survival at 12 months after randomization
Allogeneic hematopoietic stem cell transplantation (HTC) is the only curative option for many patients with hematologic malignancies but >50% of this patients will develop extensive chronic graft-versus-host disease (cGVHD), which remains the most important complication after HTC. Classically, the most effective strategies to prevent GVHD have not improved survival; therefore, the new strategies are being sought. This study is designed in two phases: the main objective for phase I study is the more suitable dose for ixazomib search. Phase II study is designed to evaluate the efficacy of ixazomib at the doses stablished in phase I.
This phase Ib/2 trial studies how well chemotherapy, total body irradiation, and post-transplant cyclophosphamide work in reducing rates of graft versus host disease in patients with hematologic malignancies undergoing a donor stem cell transplant. Drugs used in the chemotherapy, such as fludarabine phosphate and melphalan hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving chemotherapy and total-body irradiation before a donor stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and 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 (called graft versus host disease). Giving cyclophosphamide after the transplant may stop this from happening.
This randomized phase III trial studies how well Lactobacillus plantarum works in preventing acute graft versus host disease in children undergoing donor stem cell transplant. Lactobacillus plantarum may help prevent the development of gastrointestinal graft versus host disease in children, adolescents, and young adults undergoing donor stem cell transplant.
This research study is studying a drug called obinutuzumab as a means of preventing chronic Graft vs. Host Disease (cGVHD).
Background: Chronic graft versus host disease (cGVHD) can affect people who had a hematopoietic stem cell transplant using donor cells. It is often fatal. It is usually treated with high doses of steroids. But that helps only about half the people in the long term. Researchers want to see if a drug called baricitinib can help people with cGVHD that has not responded to therapy. The drug inhibits the proteins involved in communication in the immune system. These proteins may play a role in cGVHD and other inflammatory diseases. Objectives: To test the safety and effectiveness of baricitinib in people with cGVHD that has not responded to therapy. Eligibility: Adults 18 and older with cGVHD that has not responded to therapy. Design: Participants will be screened with a medical history, physical exam, and blood and urine tests. They will have lung and heart tests and chest scans. Baseline visit: Participants will have: Medical history Physical exam Blood tests Tests for infectious diseases Skin, eye, and teeth evaluations Rehabilitation and occupational medicine evaluations Photos of any lesions Gynecology evaluation (females) The study will occur in 28-day cycles. Participants will take the study drug by mouth every day for 3 cycles. Some will take it for 3 or 6 more cycles. Participants will have a few visits during each cycle. They will repeat some previous tests. They may also have scans and questionnaires. Participants will have a visit when they stop taking the drug and another 3 months later. They will repeat a few study tests. They will have follow-up calls for 2 years.
This research study is evaluating a combination of a therapy called Extra-corporeal Photopheresis (ECP) with a drug called Interleukin-2 (IL-2) as a possible treatment for chronic graft-versus-host-disease (GVHD) following allogeneic stem cell transplant.
Graft-versus-Host Disease (GVHD), is the most frequent and severe complication of allogeneic hematopoietic stem cell transplantation (HSCT). Much of our knowledge on the pathophysiology of GVHD has been gained from experimental models but far less from the study of the disease in humans. Recent developments in basic biology open new avenues to the development of biomarker sets that could predict GVHD severity and prognosis that could be tested and validated through well-designed multicenter clinical trials. The main goal of this project is to further our understanding of the pathogenic mechanisms of human GVHD on one hand, and of functional immune tolerance on the other. Furthermore, this study aims at setting up a clinically relevant biomarker set in human GVHD and immune tolerance in a discovery cohort. The objectives of this project are: 1. To define phenotypic, functional and molecular correlates of acute GVHD early after HSCT/at its onset 2. To study thymic reconstitution and the T-cell repertoire after HSCT during period 2 3. To identify functional and molecular correlates of immune tolerance in long-term survivors of HSCT 4. Preparing for biomarker validation into a clinical trial We propose a prospective analysis of a cohort of 680 patients transplanted from an HLA-identical sibling donor at Saint Louis hospital. Analyses will be performed during 3 critical, clinically relevant, periods. 1. Period 1: Analysis at the onset of GVHD, or at the time of engraftment 30 days after HSCT in patients not developing GVHD. An additional blood sample will also be analyzed 90 days after HSCT. 2. Period 2: Thymic function analysis using measurements of T-cell receptor excision circles (TREC) will be performed at 6 and 12 months post-transplant for all patients. T-cell receptor analysis on sorted T-cell populations will be performed by NGS. 3. Period 3: In "tolerant" patients (patients more than 2 years after HSCT not requiring immunosuppressive treatment), or in patients still requiring immunosuppressive therapy after 2 years. We will also analyze the corresponding immune parameters for each donor. The longitudinal design of this study will allow us to provide an integrated view of GVHD pathophysiology and mechanisms of immune tolerance in human. Prospectively identified phenotypic, molecular or functional biomarkers will then be tested, in a subsequent study, from biological materials prospectively collected within the French wide CryoStem cohort. Thus, as the final task of this project, we will perform statistical analyses taking into account confounding clinical variables influencing the outcome (i.e. GVHD-related death or tolerance). Preparing for a clinical trial will need moving from classical Bioinformatics analyses into clinically relevant statistical analyses that include sequential biological measurement in the discovery set cohort. Main points that will be taken into accounts for this task are the followings; 1. Transplant-related mortality (TRM) can be estimated in the range of 20%; 2year post-allogeneic HSCT 2. TRM is mostly (even if totally) due to GVHD and its associated immune deficiency 3. GVHD cumulative incidence can be estimated in the range of 40% 4. 80 patients will be prospectively studied and 30 patients will be analyzed (cross sectional study) for part 3 only. 5. Since GVHD-related mortality and tolerance are mutually exclusive situation the optimal calculation for the validation cohort can be expected 6. This calculation will be the basis for the proposal of an interventional clinical trial.
Chronic graft-versus-host disease (cGVHD) can be hard to diagnose, difficult to manage and contributes significantly to morbidity and mortality in hematopoietic stem cell transplantation patients. The research will look into identifying and validating cGVHD biological indicators (=bio-markers) which will be evaluated whether they can predict a future development of the disease. The study hypothesis is that a number of previously reported cGVHD bio-markers, known to be present at the time of cGVHD diagnosis, will also be present at earlier time points, before cGVHD develops. Following validation, the bio-markers will be beneficial for finding those patients who are in higher risk to develop cGVHD. By identifying the higher-risk group, which is more likely to develop cGVHD, a pre-emptive therapy might be applied in order to prevent or reduce the prevalence of the disease.
This research study is a Phase I clinical trial, which tests the safety of an investigational combination of IL-2 plus donor anti-inflammatory Treg cells and also tries to define the appropriate dose of the investigational combination of IL-2 plus donor anti-inflammatory Treg cells to use for further studies. IL-2 is involved with cell signaling and regulation of white blood cells (WBCs). WBCs are part of the immune system. Treg cells are also part of the immune system; they are involved with anti-inflammatory responses. "Investigational" means that the combination of IL-2 and anti-inflammatory Treg cell infusion is being studied. It also means that the FDA (U.S. Food and Drug Administration) has not approved the combination of IL-2 and anti-inflammatory Treg cell infusion for use in people with cGVHD. Chronic GVHD is a medical condition that may occur after you have received your bone marrow, stem cell or cord blood transplant from a donor. The donor's immune system may recognize your body (the host) as foreign and attempt to 'reject' it. This process is known as graft-versus-host disease. Traditional standard therapy to treat cGVHD is prednisone (steroids). Participants on this trial have not responded to steroid therapy. The investigators are looking to assess the safety and optimal dose for the combination of IL-2 plus donor anti-inflammatory Treg cells, that may help control cGVHD by stopping the donor's immune system from 'rejecting' your body.
