Filter by:The purpose of this study is to determine the recommended phase 2 dose of the drug Vorinostat in children, adolescents and young adults following allogeneic blood or marrow transplant (BMT) and determine whether the addition of Vorinostat to the standard graft versus host disease (GVHD) prophylaxis will reduce the incidence of GVHD.
This is a prospective study that aimed to observe the therapeutic effects of minor salivary gland transplantation for cicatrizing conjunctivitis patients.
RATIONALE: Following stem cell transplantation, a major risk is graft-versus-host disease (GVHD). This occurs when donor immune cells that have been infused recognise the host's cells as 'foreign' and attack these cells. Prevention of GVHD relies upon depletion of donor immune T cells or drugs that block T cell function. However, these methods also increase the risk of life threatening infection. There is an important unmet need for better means of accelerating immune recovery following stem cell transplantation while avoiding GVHD. Pre-clinical studies have shown that infusion of donor CD62L- effector memory T cells (Tem) into the host improve immune recovery after allo-Stem Cell Transplant but do not cause GVHD. PURPOSE: This phase I dose escalation trial aims to determine the feasibility and safety of transfer of donor Tem following allogeneic stem cell transplantation.
Acute graft-versus-host-disease (aGvHD) is a typical complication after allogeneic hematopoetic stem cell transplantation (ASCT). About 30-60% of patients after ASCT are affected by aGvHD, which constitutes a relevant burden of morbidity and mortality in these patients. Fecal microbiota transplantation (FMT) is a therapeutic concept to treat intestinal dysbiosis of various origin by infusion of the stool microbiota of a healthy donor into the gastrointestinal tract (GI) of a patient. FMT can be performed endoscopically by colonoscopic deployment of the donor microbiota into the patient´s caecum and terminal ileum. Patients with gastrointestinal aGvHD (GI-aGvHD) are known to comprise a significant dysbiotic colonic microbiota that can be attenuated by FMT.
This study aims to evaluate the clinical efficacy of cyclophosphamide in patients receiving a bone marrow graft from a matched unrelated donor in overall survival, progression free survival and cumulative incidence of acute and chronic GvHD. Thirty patients will receive cyclophosphamide while twenty patients will receive antihuman T-lymphocyte immune globulin (ATG).
This study is a Phase 2/3 prospective, double-blind, randomized, multi-center, placebo-controlled study for prevention of acute GVHD (aGVHD) in subjects undergoing an allogeneic hematopoietic cell transplant (HCT).
This phase II trial studies how well naive T-cell depletion works in preventing chronic graft-versus-host disease in children and young adults with blood cancers undergoing donor stem cell transplant. Sometimes the transplanted white blood cells from a donor attack the body's normal tissues (called graft versus host disease). Removing a particular type of T cell (naive T cells) from the donor cells before the transplant may stop this from happening.
This is a Single arm clinical study evaluating the safety and efficacy of hAECs in preventing aGVHD after HSCT.
Dry eye disease, ocular graft-versus-host disease (GVHD), and superior limbic keratoconjunctivitis (SLK) are all ocular surface disorders which mostly involve the outer surface of the eye. Many of the ocular surface disorders may result from or be aggravated by the mechanical stress from eyelid blinking. Specifically, SLK is an inflammatory ocular surface disorder characterizing by redundant superior bulbar conjunctiva. Since redundant superior bulbar conjunctiva can cause a significant mechanical force during eyelid blinking, we found that conjunctival resection with Tenon's capsule excision is helpful in relieving the symptoms of SLK patients. Therapeutic contact lens, protecting the ocular surface from the microtrauma between eyelid and ocular surface, is also an effective treatment for severe dry eye disease, ocular GVHD, and SLK. Although shearing force/mechanical stress has been studied in many different tissues and disease entities, the impact of shearing force over ocular surface is still unclear. While the importance of mechanical stress in ocular surface disorder has been reported, the specific molecule involving the pathogenesis is still unknown. Diadenosine polyphosphates are a family of dinucleotides. They can enhance tear secretion and increase corneal wound healing rate from previous reports. Shear-stress stimuli was also noted to be able to induce diadenosine polyphosphates releasing from human corneal epithelium. In addition, mucin, one of the three components of tear film, has been greatly emphasized in the pathogenesis of dry eye disease. There are also some reports about the shearing force compensating the mucin contents in the inflammatory lung/bowel diseases. If diadenosine polyphosphates or mucin indeed play a role in mechanical stress-related ocular surface disorders, it will be a promising therapeutic targeting in the future.
The granulocyte colony-stimulating factor (G-CSF)+antithymocyte globulin (ATG)-based protocols and posttransplantation cyclophosphamide (PTCy) protocols have been widely used for graft-versus-host disease (GVHD) prophylaxis in haploidentical related donor transplantation (haplo-HSCT). Nevertheless, severe acute GVHD remains an obstacle for haplo-HSCT. This study is aim to evaluate the efficacy of a modified protocol that includes PTCY and ATG in recipients of haplo-HSCT.
