Filter by:Despite significant progress in overall survival and event-free survival in Pediatric Hematopoietic Stem Cell Transplant (HSCT), therapeutic options for graft-versus-host disease control remain limited, particularly in steroid-refractory patients. Several strategies have been proposed in the last 20 years but so far, the results have been inconclusive, complicated by the small population afflicted, inconsistent treatment schedules, different disease classifications and diagnosis methods. The number of studies concerning pediatric patients are even smaller. First line therapy for acute graft-versus-host disease (aGVHD) is steroid treatment that achieve partial or complete remission of the disease in a variable percentage of cases (40-60%), depending mainly to severity of GVHD and number of organ involvement, with hepatic and gastrointestinal GVHD particularly refractory to steroid treatment. For second line therapy there is no a standardized strategy with a great variety of immunosuppressive treatment without a real superiority of a drug in comparison to another. Steroid refractory acute GVHD is therefore one of the most important challenges in HSCT field. One of the more promising routes, based on published data and clinical experience, is the off-label use of Infliximab, an anti-Tumor Necrosis Factor α drug (already approved for many rheumatologic and autoimmune diseases) administered as a second line treatment in patients with steroid-refractory aGVHD at the standardized dosage of 10 mg/kg, although limited evidence has been published to validate this subscription. Biological pattern that could explain susceptibly of GVHD to infliximab treatment could lie in physiopathology of acute gastrointestinal GVHD that may resemble ulcerative rectocolitis. In this case, relation to Therapeutic Drug Monitoring (TDM) and Tumor Necrosis Factor α (TNFα) levels could be critical in monitoring the efficacy of the drug and need of further doses. Limited published data and clinical experience show that Infliximab may be able to further control symptoms and inflammatory response in a promising percentage of treated patients, although some have no benefit from the treatment. The aim of this study is to analyze the role of TNFα concentration in aGVHD, its levels fluctuation and clinical response of GVHD to Infliximab treatment in steroid-refractory pediatric patients.
While hematopoietic stem cell transplant (HSCT) is an effective therapy, graft versus host disease (GVHD) is the most significant complication after HSCT. Both acute GVHD and chronic GVHD are leading causes of non-relapse morbidity and mortality. Patients with solid organ transplants may participate in this study as well because these patients occasionally develop acute GVHD, which is biologically similar to acute GVHD after an HSCT. Acute graft versus host disease usually occurs within the first 100 days of transplant and can involve the skin, gut, or liver. Chronic graft versus host disease usually occurs after the first 100 days of transplant and can involve skin, eyes, mouth, joints, liver, intestines commonly. These two diseases are different, but both happen due to the imbalance of the donor immune system in the host. The purpose of this research is to learn more about ruxolitinib as a treatment for both acute and chronic GVHD. Specifically, the investigators would like to learn more about the pharmacokinetics (PK - the process of absorption, distribution, metabolism, and elimination from the body - meaning how the drug moves through the body) and the pharmacodynamics (PD - the body's biological response to the drug) of ruxolitinib.
This is a Phase Ib, open-label, multicenter, dose-escalation study to evaluate the safety, tolerability, and pharmacokinetics of Efmarodocokin Alfa and to make a preliminary assessment of activity of Efmarodocokin Alfa in combination with standard-of-care (SOC) in the prevention of acute graft-versus-host disease (aGVHD) in participants undergoing allogeneic hematopoietic stem cell transplantation (HSCT).
This Phase II open label study will evaluate the safety and efficacy of repeat doses of RGI-2001 in combination with standard of care treatment for the prevention of acute graft-vs-host-disease (aGvHD) in subjects following Allogeneic Hematopoietic Stem Cell Transplantation (alloHSCT). These subjects will be compared to contemporary controls.
This is a multi-center study to evaluate the safety, tolerability, PK, PD, and clinical activity of EQ001 in subjects with Acute Graft Versus Host Disease (aGVHD).
The purpose of this study is to assess the safety and tolerability of itacitinib in combination with corticosteroids in Japanese subjects with Grades II to IV acute graft-versus-host disease (aGVHD).
The study is an open-label, single-arm, Phase I/II multi-center study to investigate the PK, activity and safety of ruxolitinib added to the patient's immunosuppressive regimen in infants, children, and adolescents ages ≥28 days to <18 years old with either grade II-IV aGvHD or grade II-IV SR-aGvHD. The trial design includes four age groups: Group 1 includes patients ≥12y to <18y, Group 2 includes patients ≥6y to <12y, Group 3 includes patients ≥2y to <6y, and Group 4 includes patients ≥28days to <2y.
This is a study comparing the defibrotide prophylaxis arm vs standard of care arm for the prevention of aGvHD.
This study evaluates the the pharmacokinetics of posaconazole (new solid oral and IV) given as prophylaxis to patients who are at risk for developing fungal infections after receiving conditioning therapy (except strictly non-myeloablative (NMA)) for allogeneic Stem Cell Transplant (SCT), remission induction chemotherapy for acute myeloid leukemia (AML) or myelo dysplastic syndrome (MDS) or being treated for severe graft versus host disease (GvHD) and determines the impact of mucositis on the pharmacokinetics of posaconazole new solid oral.
This study is a Phase 1, non-randomized, open-label/Phase 2 randomized, blinded study of ProTmune (ex vivo programmed mobilized peripheral blood cells) versus non-programmed mobilized peripheral blood cells for allogeneic hematopoietic cell transplantation (HCT) in adult subjects aged 18 years and older with hematologic malignancies. A total of 88 study subjects were treated in the trial at approximately 15 centers in the US.
