16 Clinical Trials for Various Conditions
This study aims to evaluate the safety and feasibility of administering AZA in conjunction with steroids as first line therapy for GI GVHD. A risk for patients who have received a transplant from another donor is graft versus host disease (GVHD). This happens because of differences between the donated cells (graft) and the patient body's cells (host). The new cells from the donor might see the patients body's cells as different and attack them. GVHD can be very serious and cause death. The standard first treatment for GVHD is corticosteroids but not all patients respond and they then have to receive other treatments. In addition, when GHVD involves the gut it can damage stem cells and can cause long term gut problems such as abdominal pain bowel disturbance. In laboratory studies giving a medicine called 5 -azacytidine (AZA) has been able to protect the gut stem cells and help them recover. In this trial the investigators would like to see if AZA can do the same thing when given with steroids in patients with GVHD. Right now, doctors and researchers don't know the best treatment for GVHD. Acute GVHD is usually treated using high-dose corticosteroids, but these don't always work well. Even if the GVHD gets better when it involves the gut there can be long term damage to gut stem cells. In the laboratory 5 azacytidine (AZA) has been able to protect gut stem cells and help them recover and the investigators would like to learn if this happens in people too. AZA has been approved by the U.S. Food and Drug Administration (FDA) for the treatment of patients with leukemias. It has also been used post transplant to try and risk the chance of leukemia coming back and to try and treat GVHD but AZA has not been approved by the FDA for the treatment of acute GVHD.
The objectives of this trial were to evaluate the safety, tolerability, pharmacokinetics/pharmacodynamics (PK/PD) and efficacy of intravenous (IV) ALXN1007 in participants with acute graft-versus-host disease (GVHD) of the lower gastrointestinal (GI) tract.
Background: The gastrointestinal (GI) tract is commonly affected by acute graft-versus-host disease (aGVHD) and chronic GVHD (cGVHD) in patients who have undergone blood or marrow stem cell transplantation (BMT). Initially, patients are treated with systemic corticosteroids, which produce complete response rates in 35 percent. Although short courses of steroids are preferred to minimize adverse effects, many patients require systemic treatment chronically since GI GVHD can negatively impact quality of life and nutrition status. One option to minimize systemic steroid exposure is by nonabsorbable corticosteroids that act locally on the GI tract. Budesonide (Entocort EC, AstraZeneca, Wilmington, DE) is an FDA-approved oral topical corticosteroid for the treatment of mild to moderate active Crohn s disease involving the ileum and/or the ascending colon, and for maintenance of clinical remission of mild to moderate Crohn s disease involving the ileum and/or the ascending colon for up to 3 months. It has a high ratio of topical-to-systemic activity with minimally active metabolites, and undergoes extensive first-pass metabolism. Since both intestinal GVHD and Crohn s disease seem to share a similar pathogenic background, budesonide has been used in the BMT setting for GI GVHD, usually in combination with systemic corticosteroids (e.g. methylprednisolone) to improve clinical response and allow for more rapid tapering of systemic corticosteroid doses. First-pass metabolism is mediated mostly by the cytochrome P450 (CYP450) enzyme system. The liver is the major site of CYP450-mediated metabolism but the enterocytes of the intestinal epithelium are also an important site for drug metabolism. Budesonide undergoes significant metabolism by CYP enzymes with substantial first-pass metabolism. The potential for greater systemic availability of orally administered budesonide exists when it is given concurrently with triazole antifungals, which are commonly prescribed for prophylaxis or treatment of fungal infections after transplantation. Fluconazole and voriconazole are moderate and strong inhibitors of CYP3A4, respectively, and budesonide is a CYP3A4 substrate. Inhibition of CYP3A4 may impair the metabolism of budesonide, resulting in systemic concentrations of budesonide and subsequently, adverse effects such as hyperglycemia. If the presence of fluconazole or voriconazole does impair budesonide s metabolism, then dose adjustments to budesonide may be warranted. There are no prospective studies evaluating the effects of fluconazole or voriconazole on budesonide s pharmacokinetics in patients who have undergone BMT. The primary objective of the proposed study is to determine the effects of fluconazole and voriconazole on the trough (Cmin) and peak (Cmax) of budesonide in patients who have undergone BMT and who have GI GVHD. The primary endpoints are the Cmin and Cmax of budesonide. Secondary endpoints include the Cmin of voriconazole. Objectives: The proposed study seeks to determine the effects of fluconazole and voriconazole on the Cminand Cmax of budesonide. Eligibility: Adult and pediatric subjects (greater than or equal to 13 years of age and greater than or equal to 49 kg) who are registered to an NCI or NHLBI protocol who have undergone a bone marrow, cord, haplo-cord or peripheral blood stem cell transplantation who have GI GVHD as determined by the medical team and who require treatment with budesonide and are candidates for antifungal therapy are eligible for this study. Design: Each subject will serve as his or her own control to minimize the variation in absorption, distribution, metabolism and elimination of oral budesonide that can occur from subject to subject, due to genetic, anatomic or other unidentified differences. For example, genetic polymorphisms of CYP2C19, which is significantly involved in voriconazole s metabolism, could otherwise affect the results of the study (i.e. CYP2C19 poor metabolizers may experience higher voriconazole serum concentrations, which could results in greater CYP3A4 inhibition and higher budesonide exposure). In addition, the longitudinal cohort design of this study will be able to answer the research questions posed with fewer research subjects. Research subjects will be accrued into one of three cohorts depending on the antifungal prophylaxis (or lack thereof) the subject is receiving at study entry and the preference of the medical team for continued antifungal coverage after the initiation of budesonide and systemic corticosteroids. Subjects who are not currently receiving antifungal prophylaxis or who are on fluconazole at baseline are eligible for enrollment in Cohort 1. Subjects in Cohorts 2 and 3 are receiving voriconazole and fluconazole at study entry, respectively. In Cohort 1, if applicable, subjects will stop fluconazole on day -1...
Determine how much voriconazole is absorbed when the product is given by mouth to children with extensive graft versus host disease after a stem cell transplantation and determine the correct dosing of voriconazole in this population. Hypothesis: Children with gastrointestinal graft versus host disease will have decreased absorption of oral voriconazole and require higher doses of voriconazole in order to prevent or treat fungal infections.
Patients with gastrointestinal graft-vs.-host disease are randomized to oral beclomethasone dipropionate (BDP) 8 mg/day or identical placebo tablets for 50 days, along with a 10-day induction course of prednisone. At study day 10, patients whose symptoms of GVHD are under control undergo a rapid prednisone taper over 7 days, while study drug is continued to study day 50. After discontinuation of study drug at study day 50, patients are followed for 30 additional days, to study day 80. The primary endpoint is treatment failure by day 50, that is, a flare of the symptoms of GVHD that requires immunosuppressive therapy. Secondary endpoints are treatment failure by day 80, treatment-emergent adverse events, and survival at transplant day 200. The hypothesis to be tested is that a topically-active corticosteroid (beclomethasone dipropionate, BDP), taken orally, would allow rapid tapering of prednisone while maintaining control of intestinal GVHD.
This phase I trial studies the side effects and how well high dose vitamin A works in preventing gastrointestinal graft versus host disease (GVHD) in participants undergoing donor stem cell transplant. Vitamin A deficiency is associated with increased risk of gastrointestinal GVHD. Vitamin A regulates growth and differentiation of intestinal cells and may reduce risk of gastrointestinal GVHD.
The aim of this trial is to assess safety and efficacy of apraglutide in subjects with steroid refractory gastrointestinal acute graft versus host disease (aGVHD).
Phase II efficacy evaluation, phase I/II efficacy and toxicity trial of recombinant human keratinocyte growth factor for the treatment of steroid refractory gastrointestinal graft versus host disease.
Gastro-Intestinal Acute Graft Versus Host Disease (GI-aGVHD) is a complication of allogeneic stem cell transplant which is usually treated with steroids. You are being asked to take part in this study because you have recently been diagnosed with GI-GVHD. The standard of care for GI-aGVHD is steroids. When aGVHD does not respond to steroids it is described as steroid-refractory aGVHD. There is no standard therapy for steroid-refractory GI-aGVHD. This study is a Phase II study. The main goal of a Phase II study is to see the efficacy and what side effects are seen with FMT as a treatment for GVHD. Fecal Microbiota Transplantation (FMT) is the transfer of fecal material from a healthy donor to a patient in order to restore the diversity of the intestinal microbiota. FMT is currently indicated for the treatment of recurrent Clostridium Difficile infection. FMT is considered experimental in this study, meaning it is not approved by the FDA for the treatment of GVHD.
This phase I trial studies the side effects of using an investigational procedure (fecal microbiota transplantation \[FMT\]) in treating patients with severe acute gut graft-versus-host-disease. The purpose of a fecal microbiota transplantation is to use feces from a healthy human donor to replace the abnormal gut bacteria in the recipient. One of the side effects of a stem cell transplant is the development of graft-versus-host disease (GvHD) in several organs including gut. GvHD is caused by the donated bone marrow or peripheral blood cells recognizing the recipient's body as foreign and attacking it. Acute gut GvHD is one of the leading causes of death after transplant. Recently, studies have shown that patients with reduced intestinal bacterial diversity in their stool during acute gut GvHD have higher overall mortality rates. The information learned from this study may offer FMT as a promising therapy for the treatment of severe acute gut graft-versus-host-disease.
This phase II trial studies how well methylprednisolone sodium succinate works in treating patients with graft-versus-host disease (GVHD) of the gastrointestinal tract that has begun within 100 days of transplant (acute GVHD). Corticosteroids are a type of drug that reduces inflammation. Giving corticosteroid drugs, such as methylprednisolone sodium succinate, directly into the arteries of the gastrointestinal tract may help treat inflammation caused by GVHD. Giving methylprednisolone sodium succinate in addition to standard treatments may be more effective in treating GVHD.
RATIONALE: Beclomethasone may be effective in treating patients who have graft-versus-host disease of the gastrointestinal tract. PURPOSE: Compassionate use of beclomethasone in treating patients who have graft-versus-host disease of the gastrointestinal tract that has not responded to previous therapy.
Use of an oral topically-active glucocorticoid with limited side effects may control the gastrointestinal inflammatory process of GVHD and minimize glucocorticoid exposure.
Use of an oral topically-active glucocorticoid with limited side effects will control the gastrointestinal inflammatory process of GVHD and minimize glucocorticoid exposure.
RATIONALE: Lithium carbonate may be an effective treatment for intestinal graft-versus-host disease caused by a donor stem cell transplant. PURPOSE: This clinical trial is studying lithium carbonate in treating patients with acute intestinal graft-versus-host-disease after donor stem cell transplant.
The goal of the Precision Diagnosis in Inflammatory Bowel Disease, Cellular Therapies, and Transplantation (PREDICT) trial is to apply a systems-biology approach to enable precision diagnostics for the key immunologic outcomes for patients with Inflammatory Bowel Disease, Cellular Therapeutics and Transplantation. This approach will deepen the understanding of the molecular mechanisms driving auto- and allo-immune diseases and serve as a critical platform upon which to design evidence-based treatment paradigms for these patients. This research study will examine the immunology of auto- and allo-immune gastrointestinal disturbances such as Inflammatory Bowel Disease (IBD), Graft-versus-Host Disease (GVHD), and Functional Gastrointestinal Disorder (FGID), as well as the immune manifestations after CAR-T and other cellular therapeutics. The Investigators seek to use blood and tissue samples in order to better understand the mechanisms driving these diseases and their therapies. The Investigators further hypothesize that longitudinal systems-based immunologic analysis will enable the patient-specific determination of the molecular evolution of IBD, GVHD and the response to cellular therapeutics, as well post-transplant defects in protective immunity, and determine which pathways, when perturbed, can cause clinical disease. The discovery of these pathways will lead to improved diagnostic, prognostic and treatment approaches, and to personalized therapeutic decision-making for these patients.
