Active clinical trials for "Graft vs Host Disease"

The study compares two acute graft-versus-host disease (aGVHD) prophylaxis regimens: efprezimod alfa vs placebo with the standard GVHD prophylaxis of tacrolimus / methotrexate. The study compares two acute graft-versus-host disease (aGVHD) prophylaxis regimens: efprezimod alfa/tacrolimus / methotrexate (efprezimod alfa/Tac/MTX) versus placebo/tacrolimus / methotrexate (placebo/Tac/MTX) in the setting of myeloablative conditioning (MAC), matched unrelated donor (MUD) allogeneic hematopoietic stem cell transplantation in participants with acute leukemia (AML/ALL) or myelodysplastic syndrome (MDS). The study agent, efprezimod alfa, will be administered through IV infusion on days -1, 14, and 28 at the dose of 480mg, 240 mg and 240mg, respectively. The placebo will be 100 ml normal saline intravenous (IV) solution.

Finding a donor remains a challenge for patients in need of an urgent hematopoietic stem cell transplantation (HSCT). The ability to obtain half matched stem cells from any family member represents a significant breakthrough in the field. Haploidentical haplo-HSCT is characterized by the nearly uniform and immediate availability of a donor and the availability of the donor for post-transplant cellular immunotherapy. However, haplo-HSCT has a high risk of Graft versus Host Disease (GvHD) and poor immune reconstitution when GvHD is prevented by all existing methods of vigorous ex vivo or in vivo T-cell depletion. Different treatment approaches are currently being explored to mitigate complications such as graft rejection, severe GvHD, and prolonged immune suppression. Novel experimental utilization of T regulatory cells, alloreactive natural killer (NK) cells, and other T cell subsets hold great promise. Cellect Biotherapeutics' platform technology, ApoGraft, is based on the findings that GvHD can be prevented by Fas receptor mediated selective depletion of T cell subsets, ex vivo. The investigators hypothesize that the use of ApoGrafts for haplo-HSCT will be safe, and reduce rates of GVHD without affecting Graft-versus-Leukemia (GvL).

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.

Some eye diseases can be helped by eye drops made from a person's own blood. These eye drops are called autologous serum eye drops, or ASEDs. ASEDs have been studied in only a few people with graft vs. host disease (GVHD) affecting the eye and were found to be helpful with few side effects. The purpose of this study was to determine whether ASEDs are safe and more effective than control (normal saline) and can help with eye symptoms in people with severe chronic eye GVHD. Each participant in this study was to have blood drawn to prepare ASEDs specifically for the participant. Each participant was scheduled to receive ASEDs for 3 months and placebo eye drops (salt water) for 3 months. Participants did not know when they were receiving the ASEDs and when they were receiving placebo eye drops.

This research study is studying the removal of a subset of white blood cells (called alpha/beta T cells) from the donor product using a cell separation device before the product is transplanted into the participant. The device used to remove the α/βT cells in this study is: -CliniMACS® TCR α/β Reagent System

The Balance study will assess the safety, tolerability, and efficacy of an investigational drug called ALPN-101 in adults with steroid-resistant or steroid-refractory acute graft versus host disease (aGVHD).

The purpose of this study is to evaluate itacitinib in combination with corticosteroids as first-line treatment of participants with Grade II to IV acute graft-versus-host disease (aGVHD).

This is an open-label, randomized, Phase 3, multicenter trial, which has been designed to compare the efficacy and safety of T-Guard to ruxolitinib in patients with Grade III or IV Steroid-Refractory acute Graft-Versus-Host Disease (SR-aGVHD). The primary hypothesis is that T-Guard treatment will improve the Day 28 complete response (CR) rate in patients with Grades III and IV SR-aGVHD compared to ruxolitinib.

Alefacept is a drug tht may reduce the number of T cells in circulation. This drug has been used in the treatment of psoriasis, which is a skin disorder also caused by T cells, like chronic GVHD. Information from studies in psoriasis and in other patients with GVHD suggests that this drug may help to treat chronic GVHD. Chronic GVHD is a medical condition that can develop after allogeneic stem cell transplantation. It occurs when the donor immune cells (the "graft") attack and damage organs and tissue (the "host"). It is thought that T cells, a subtype of immune cells, are responsible for the tissue damage in chronic GVHD. In this research study we are looking to see how well Alefacept works in treating chronic GVHD that has not resolved after therapy with corticosteroids.

[Study Objectives] To evaluate the efficacy of azithromycin, N-acetylcystein, and inhaled corticosteroid combination therapy in patients with bronchiolitis obliterans as a complication of allogeneic hematopoietic cell transplantation in terms of response rate at 6 months after treatment initiation based on the improvement of FEV1.
