Filter by:This study is a prospective randomized placebo-controlled phase 2 study to compare CYP-001 plus corticosteroids (CS) to placebo plus CS in allogeneic hematologic stem cell transplant recipients with HR-aGvHD. Severity of GvHD will be assessed at screening and throughout the study using Mount Sinai Acute GvHD International Consortium (MAGIC) guidelines. Eligible subjects will be randomized to receive either CYP-001 IV infusion on Days 0 and 4 or placebo on the same days. All subjects will receive ongoing CS therapy as appropriate per institutional guidelines. Subjects will have study visits up to Day 100 during the Primary Evaluation Period. During the Follow-Up Period, subjects will have study visits up to 24 months.
In children receiving a hematopoietic stem cell transplant (HSCT), blood levels of TNFalpha (an inflammatory cytokine) at the onset of the acute GVHD (graft-versus-host disease) could be correlated with the severity of the disease. The hypothesis is that the highest infliximab (a biologic drug against TNFalpha) could be associated with a significant reduction in TNFa levels and, subsequently, with a faster remission of the symptoms and prevention of disease progression. Moreover, a rapid drop of infliximab serum concentration, documented by therapeutic drug monitoring (TDM), could be related to the active phase of GVHD and higher production of TNFalpha. Therefore, the study is aimed at investigating whether the drop in infliximab plasma concentrations could be associated with clinical response and production of TNFalpha. HSCT children receiving infliximab to control GVHD are enrolled. Blood samples will be collected during treatment and they serve to measure drug and TNFalpha concentrations. Drug levels are analyzed by a population pharmacokinetic modeling and results are compared with plasma concentrations of TNFalfa and clinical response.
To evaluation the efficacy and safety of autologous fecal bacteria transplantation in preventing acute graft versus host disease after haploidentical hematopoietic stem cell transplantation. Bone marrow transplant patients were recruited.
We believe that CEC, besides coming from cells shedding from patient vasculature, could partly belong to donor, originating from the cellular graft.
The investigators hypothesize that perturbations in the intestinal microbiota following allogeneic hematopoietic stem cell transplantation (HSCT) are essential for the development and propagation of acute graft-versus-host disease. Therefore, modification of HSCT recipients' gut microbiota using fecal transplantation from a healthy donor could be used to treat gut acute GVHD. The study evaluates safety and feasibility of fecal microbiota transplantation with frozen capsules from healthy donors for the treatment of steroid resistant or steroid dependent acute graft-versus-host disease of the gut.
