25 Clinical Trials for Various Conditions
This study aims to evaluate the efficacy and safety of crovalimab in pediatric participants with aHUS.
The purpose of this Phase 3 study is to determine whether iptacopan (LNP023) is efficacious and safe for the treatment of aHUS in adult patients who are treatment naive to complement inhibitor therapy.
This study aims to evaluate the efficacy and safety of crovalimab in adult and adolescent participants with aHUS.
Hematopoietic stem cell transplantation (HCT)-associated thrombotic microangiopathy (TMA) is an understudied complication of HCT that significantly affects transplant related morbidity and mortality. The investigators hypothesize that early intervention with complement blocker eculizumab will double survival in HCT recipients with high risk TMA, as compared to historical untreated controls. An optimal eculizumab dosing schedule can be determined for this population through eculizumab pharmacokinetic/pharmacodynamic (PK/PD) testing.
The purpose of this study is to evaluate the platelet count change from baseline and safety of OMS721 in adults and adolescents with atypical hemolytic uremic syndrome (aHUS). The study will also evaluate pharmacokinetics (PK), pharmacodynamics (PD), and anti-drug antibody response (ADA).
The purpose of the study is to assess the efficacy of ravulizumab to control disease activity in children and adolescents with aHUS who have not previously used a complement inhibitor (complement inhibitor treatment-naïve), as well as in complement inhibitor-experienced (eculizumab-experienced) adolescent participants.
The purpose of the study is to assess the safety and efficacy of ravulizumab to control disease activity in adolescent and adult participants with aHUS who had not previously used a complement inhibitor.
This was a prospective, open-label study with no participant randomization. Treatment for aHUS was observational and at the discretion of the treating physician. The purpose of this study was to assess disease manifestations of complement-mediated thrombotic microangiopathy (TMA) and evaluate potential clinical predictors of disease manifestations and progression in participants with aHUS with or without eculizumab treatment in the clinical setting.
The objective of this retrospective trial is to assess safety and efficacy of eculizumab in aHUS patients treated outside of an Alexion-sponsored controlled clinical trial.
Post-marketing safety data on patients treated and untreated with eculizumab or ravulizumab.
The record Primary purpose is to assess the efficacy of eculizumab in adult patients with Atypical Hemolytic- Uremic Syndrome (aHUS) to control Thrombotic Microangiopathy (TMA) as characterized by thrombocytopenia, hemolysis and renal impairment.
The primary purpose is to assess the efficacy and safety of eculizumab in pediatric patients with aHUS to control TMA as characterized by thrombocytopenia, hemolysis and renal impairment.
OBJECTIVES: I. Determine the effect of SYNSORB Pk therapy on mortality and frequency of severe extrarenal complications observed in children with acute stage E. coli-associated hemolytic uremic syndrome. II. Determine the effect of SYNSORB Pk therapy on the need for the duration of dialysis in these patients. III. Determine the effect of SYNSORB Pk therapy on the recovery of renal function and resolution of urinary abnormalities in these patients.
The investigators propose to characterize MPs in aHUS and TTP both at the onset and throughout treatment. The investigators believe that the number, size, and cell origin of MPs will differ between these two diseases. The hypothesis is that endothelial derived MPs will be higher in number and comprise a larger portion of the MP population in aHUS and that platelet MPs will comprise a larger number and greater proportion of MPs in TTP. The investigators believe that MP identity and number can be used to reliably differentiate between aHUS and TTP at disease onset.
There is growing but limited information on the long term clinical status of aHUS patients who have previously received or are continuing to receive treatment with eculizumab. This study is designed to collect clinical data that will provide insight into the long-term outcomes of patients with aHUS.
The purpose of this study is to determine whether eculizumab is safe and effective in the treatment of adolescent patients with plasma therapy-resistant Atypical Hemolytic-Uremic Syndrome (aHUS).
The purpose of this study is to determine whether eculizumab is safe and effective in the treatment of adult patients with plasma therapy-resistant Atypical Hemolytic-Uremic Syndrome (aHUS).
The primary objective of this study is to describe the frequency and characteristics of pregnancy outcomes and maternal complications among participants exposed to Ultomiris and to describe the frequency and characteristics of selected fetal/neonatal/infant outcomes in utero, at birth, and through 1 year of age after exposure in utero or via breastmilk.
The objective of this study is to determine if early high volume intravenous fluid administration (hyperhydration) may be effective in mitigating or preventing complications of shiga toxin-producing E. coli (STEC) infection in children and adolescents when compared with traditional approaches (conservative fluid management).
This registry will collect clinical data and store biosamples (seru, plasma, urine, and DNA) annually from pediatric patients with thrombotic mcroangiopathy
To understand how AKI (Acute Kidney Injury) leads to chronic kidney disease so therapies can be found to alter the progression of events thereby significantly impacting the long-term outcomes of children who develop AKI.
The primary objective of this study will be to evaluate the drug-drug interaction potential of CCX168 with concomitant medications, as either a perpetrator or a victim, following oral administration of CCX168 to healthy participants.
This study is being conducted to satisfy a post-marketing requirement (PMR) to provide evidence characterizing 1) the safety of moxetumomab pasudotox-tdfk in patients who are 65 years of age and older and/or 2) the safety of moxetumomab pasudotox-tdfk in patients who have moderate renal impairment defined as an estimated GFR of 30-59 ml/min
Background: - Researchers who are studying hairy cell leukemia, and how the disease compares with other disorders, are interested in obtaining additional samples from leukemia patients and healthy volunteers. The investigators are particularly interested in samples from individuals who have diseases that can be treated with a new type of drug called immunotoxin, in which an antibody carrying a toxin binds to a cancer cell and allows the toxin to kill the cell. Objectives: - To collect a variety of clinical samples, including blood, urine, lymph samples, and other tissues, in order to study the samples and develop new treatments for leukemia. Eligibility: - Individuals 18 years of age and older who have been diagnosed with leukemia or other kinds of blood and lymphatic system cancers, or who are healthy volunteers. Design: * Individuals who have leukemia will be asked to provide blood, bone marrow, urine, and tumor tissue samples as requested by the researchers. Healthy volunteers will provide only blood and urine samples. * No treatment will be given as part of this protocol.
A comparative trial where all patients will receive daily doses of tacrolimus (TAC) until day +60 when tapering will begin, in the absence of graft-versus-host disease (GVHD), and discontinued by day +180. In addition patients will be randomized to methotrexate (MTX) or mycophenolate mofetil (MMF) and again, in the absence of GVHD, a tapering schedule will begin on day +240 and be completed on day +360. Doses will be adjusted to maintain blood levels.
