Active clinical trials for "Graft vs Host Disease"

The purpose of this study is to evaluate the utility of treating patients experiencing refractory chronic graft-versus-host disease with ex-vivo-expanded BM-drived mesenchymal stem cells from third-party donors. The objective was to evaluate the effect and safety of such treatment on refractory chronic graft-versus-host disease.

The primary purpose of the study is to evaluate the safety and efficacy of mesenchymal stem cells (MSC) for the treatment of patients who have developed an extensive chronic graft versus host disease (with skin and/or liver damage) after HSCs transplantation and do not respond to first-line therapy. The secondary purpose of the study is to evaluate the effect of mesenchymal stem cells (MSC) on one-year survival rate, long-term survival rate, life quality and recurrence of patients who have developed an extensive chronic graft versus host disease (with skin and/or liver damage) after HSCs transplantation and do not respond to hormone treatment.

The purpose of this study is to see if bortezomib (Velcade) is effective in the treatment of refractory cGVHD.

RATIONALE: Studying a diagnostic biomarker test in blood samples from patients who have undergone a donor stem cell transplant for cancer may help doctors plan treatment. PURPOSE: This clinical trial is studying an immunologic diagnostic blood test to see how well it works in predicting side-effects in patients with hematologic cancer or other disorders who have undergone a donor stem cell transplant.

Graft-versus-host disease (GVHD) contributes substantially to transplant-related morbidity and mortality. Steroids remains first line therapy for acute GVHD but there is currently no consensus on second line therapy for those in whom steroids have been ineffective. Basiliximab has been shown to be a safe and effective immunosuppresant in the prevention and treatment of rejection after renal transplantation and its role in acute GVHD prophylaxis and treatment has been described favourably. This is a randomized control trial to investigate its efficacy and safety in the management of acute GVHD post allogeneic stem cell transplantation (SCT).

Clinical trial based on the use of a new therapeutic strategy (MSC infusion) for the treatment of patients who have developed a GVHD refractory to the usual therapeutic measures after undergoing an allogenic hematopoietic stem cell transplant.

RATIONALE: Studying samples of tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to chronic graft-versus-host disease in patients who have undergone donor stem cell transplant. PURPOSE: This phase I trial is studying chronic graft-versus-host disease in patients who have undergone donor stem cell transplant.

OBJECTIVES: I. Determine the efficacy of unrelated donor hematopoietic stem cell transplantation in the treatment of patients with life threatening hemophagocytic disorders. II. Determine the rate of disease free survival, incidence of graft failure, and incidence of graft versus host disease in these patients after undergoing this treatment regimen.

The study aims to evaluate the safety and efficacy of fecal microbiota transplantation (FMT) for the treatment of steroid resistant graft-versus-host-disease (GVHD) of the gut. This strategy might offer a safe and effective therapeutic approach for these patients with a poor prognosis and limited therapeutic options.

Background: Graft-versus-host disease (GVHD) is a devastating complication following allogeneic hematopoietic stem cell transplantation (HSCT) mediated by stimulation of antigen presenting cells (APCs) which leads to donor T-lymphocytes activation and target tissue destruction, particularly affecting the skin, gastrointestinal tract, and liver in acute setting. In recent years, researchers have discovered that the application of mesenchymal stromal cells (MSCs) as salvage treatment among steroid refractory GVHD patients improves outcomes without long-term risk association. On the other hand, the use of MSCs concurrently with steroids as front-line treatment for acute GVHD has yet to be researched on. The investigators hypothesize that this approach, as the MSCs will be administered at earlier stage of the disease, will increase survival rate and reduce mortality among aGVHD patients. Objective: In this study, the investigators aim to determine the efficacy and safety of allogeneic infusion of Cytopeutics® umbilical cord-derived mesenchymal stromal cells (Cyto-MSC) in combination of standard corticosteroid therapy as front-line approach for treatment of grade II-IV acute GVHD patients. Study design: This is a phase I/II clinical study involving patients who underwent an allogeneic HSCT for malignant or non malignant haematological disorders and developed grade II-IV acute GVHD. A total of 40 eligible patients will be recruited in this study. For Phase I open labelled study, 5 eligible patients will be recruited to receive Cyto-MSC (5 million UC-MSCs per kg bodyweight) and standard treatment. Meanwhile, for Phase II double blinded placebo controlled study, another 35 eligible patients will be recruited and randomized into 2 study groups where 15 patients will be assigned into Group A to receive Cyto-MSC (5 million UCMSCs per kg bodyweight) and standard treatment, meanwhile another 20 patients will be assigned into Group B to receive Placebo and standard treatment. Cyto-MSC or Placebo will be administered at Day 1 and Day 4. Another infusion of Cyto-MSC or Placebo will be given at Day 7 if the patient shows no or partial response based on GvHD grading criteria. All patients will be assessed up until 6 months follow-up which include medical history, clinical and physical evaluations, pathology investigations, biomarkers and immune cell subsets analysis, as well as quality of life questionnaires.
