Filter by:This Phase 1 clinical study is designed to examine the safety and feasibility of using anti-CD3/CD28 activated marrow infiltrating lymphocytes (MILs) as treatment of relapse after allogeneic hematopoietic cell transplantation (alloHCT) for patients with hematologic malignancies with bone marrow involvement of their relapsed disease. These MILs will be derived from the bone marrow of the relapsed patient who had previously received post-transplantation cyclophosphamide (PTCy) as graft-versus-host disease (GVHD) prophylaxis (PTCy-MILs). A bone marrow aspiration will be performed on the patient to collect ~200ml of marrow for ex vivo expansion. During this expansion process, T cells will be activated and expanded by co-stimulation with anti-CD3/anti-CD28 monoclonal antibodies covalently attached to super-paramagnetic microbeads. Patients will be treated with salvage therapy while this ex vivo expansion is ongoing. After the simultaneous salvage therapy and ex vivo expansion, the activated PTCy-MILs will be reinfused. Patients will be monitored with the primary objective being the feasibility of expanding to targeted dose levels activated PTCy-MILs that do not cause grade III-IV acute GVHD within the first 90 days after PTCy-MIL infusion.
The purpose of this study is to evaluate the basiliximab for prevention of graft-versus-host disease in unrelated allo-genetic hematopoietic stem cell transplantation for thalassemia major. The objective was to evaluate the effect and safety of basiliximab for acute graft-versus-host disease.
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.
The stud will evaluate whether infusions of CD45RA-depleted lymphocytes from the donor early post-transplant is a safe way to improve immunity to common infections in recipients of TCR-alpha/beta depleted hematopoietic stem cell grafts.
This pilot clinical trial studies how well vismodegib works in treating patients with chronic graft-versus-host disease that did not respond to previous steroid treatment. Chronic graft-versus-host disease can cause a build-up of scar tissue under the skin and lead to symptoms such as sclerodermatous skin changes, dry mouth, dry eye, narrowing of the esophagus, or vaginal graft-versus-host disease. Vismodegib may work against the build-up of scar tissue and be a better treatment for chronic graft-versus-host disease caused by a hematopoietic stem cell transplant.
Background: - Some allogeneic stem cell transplant recipients get acute graft-versus-host disease (GVHD). They always get steroids as the first treatment, but this may not work. Those people where steroids are not enough may benefit from a treatment called extracorporeal photopheresis (ECP). ECP exposes white blood cells to ultraviolet light outside the body. Researchers want to study how certain markers in the blood predict the severity and outcome of acute GVHD and how ECP treatments work for people with acute GVHD. They will also study how these markers in the blood may help predict who should get ECP and its effects on the immune system. Objectives: - To learn more about treatments for acute GVHD after allogeneic stem cell transplantation. Eligibility: - Adults with acute GVHD enrolled in an National Cancer Institute (NCI) allogeneic transplantation protocol. Design: - Transplant physicians will confirm participant eligibility. - Participants will receive treatment with steroids for their acute GVHD as prescribed by their transplant physician. This will continue while they are enrolled on this study. - If steroids work in treating their acute GVHD, then every 28 days for 6 months, participants will have: - a physical exam. - blood tests. - If steroids do not work, participants will get additional treatments as prescribed by their transplant physician who may choose to use ECP as a part of this additional treatment. For ECP, blood is removed through an intravenous (IV) catheter. A machine separates the white blood cells from the other blood parts. Those cells are treated with methoxsalen and exposed to ultraviolet light. Then they are returned to the participant through their IV. - Participants who get ECP will over at least 6 months have: - veins researched. They may have a catheter placed in a larger vein in the chest or groin. - multiple blood tests. - multiple pregnancy tests (if needed). - multiple ECP procedures. - At the end of ECP treatment and 6 months after ECP, participants will have additional physical exams and blood tests.
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.
This observational study is proposed to observe the effect of high-dose, post-transplantation cyclophosphamide after a T cell-replete, HLA-matched PBSC graft from an HLA-identical or mismatched donor.
Chronic Graft-versus-Host Disease (cGvHD) is a potentially lethal disorder. A variety of second line immunosuppressive agents have been investigated but no optimal treatment has emerged. There is therefore a need for novel treatment strategies. Mesenchymal stromal cells (MSC) exhibit immunomodulatory properties and a recent pilot study suggests a response rate of 70% in steroid- refractory patients. In the present randomized study the efficacy and safety of MSC treatment will be further studied in patients with cGvHD.
