49 Clinical Trials for Various Conditions
The main purpose of this trial is to demonstrate the safety, tolerability and pharmacokinetics (PK) of CXA-10, at potentially therapeutic doses, in the target patient population comprised of subjects with Stage 3 and 4 chronic kidney injury (CKI). In addition, associated pharmacodynamic (PD) effects of CXA-10 will be investigated.
Patients with Stage 3B, 4,or 5 Chronic Kidney Disease who are to undergo an angiography procedure with contrast agent will be asked if they are willing to join the trial. If so they will be screened and randomized to receive either sodium bicarbonate or saline before, during and after the contrast media is given. They will be asked for serum samples 1 to 3 days, 7, 30, 90 and 180 days after the procedure to evaluate whether the sodium bicarbonate has reduced the incidence of contrast induced chronic kidney disease by measuring their serum creatinine, as well as whether they have required renal dialysis or other renal replacement therapy.
This will be the first-in-human (FIH) study with the oral formulation of CXA-10. The main purpose of this trial is to demonstrate the safety, tolerability and pharmacokinetics (PK) of CXA-10 and its metabolite(s) administered as single ascending oral doses to healthy volunteers (Part A). The effects of food on the PK of CXA-10 will also be investigated (Part B).
To understand the long-term epidemiology, develop effective risk-prediction and stratification tools, and understand the pathobiology of kidney disease in COVID-19 survivors.
This study is designed to assess the effectiveness of eculizumab in recipients of kidney transplantation with donor-specific antibodies (DSA) and worsening kidney function and to assess if eculizumab improves endothelial cell injury in the kidney. The investigators hypothesize that complement inhibition with eculizumab will reduce allograft injury, resulting from less complement-mediated injury of endothelial cells and less endothelial cell activation.
Obstructive sleep apnea (OSA) is a common and undertreated condition in patients with chronic kidney disease (CKD). Both physiologic and empiric data suggest that renal hypoxia due to OSA is associated with worsening kidney function. Hospitalized patients are often exposed to multiple nephrotoxins such as antibiotics, contrast agents, and diuretics, which place them at risk for acute worsening of kidney function. This study aims to determine whether immediate diagnosis and treatment of OSA in CKD patients will decrease the incidence of acute kidney injury during hospitalization. The investigators will evaluate the extent to which this effect can be attributed to a decrease in nocturnal hypoxia and improved blood pressure control. Secondary endpoints include hospital length of stay, and a composite outcome comprised of hemodialysis initiation, major cardiovascular events, and mortality.
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.
Chronic kidney disease CKD is estimated to affect nearly over 800 million people globally today (with roughly 125,000 people ending up annually on dialysis in the United States alone. CKD is a contributor to illness and is associated with a diminished quality of life and reduced life expectancy . In this study we are using a novel drug to target improved function of the kidneys.
There is a growing focus on short- and long-term kidney health in neonates, including those with acute kidney injury (AKI). AKI occurs commonly in the Neonatal Intensive Care Unit (NICU) and is associated with adverse outcomes. In addition to poor outcomes during the hospitalization, infants discharged from the NICU may have an increased burden of kidney disease during childhood. Studies of long-term kidney function in children born prematurely show a fourfold increase in chronic kidney disease (CKD) by adolescence and into adulthood. Despite the landmark findings of the Assessment of Worldwide Acute Kidney Injury Epidemiology in Neonates (AWAKEN) study, the limitations of this study are notable. First, the AWAKEN study enrolled infants admitted in 2014, making the data now over 10 years old. Much has changed in neonatal practice (e.g. increased AKI awareness, treatment strategies). Secondly, the findings of the AWAKEN study were geographically limited. While the AWAKEN study was multi-national and multi-center, it represented only 24 centers (22 from North America, 1 from India and 1 from Australia). Finally, information collected from AWAKEN ended at hospital discharge. The investigators seek to leverage the strength of the Neonatal Kidney Collaborative along with other organizations and collaboratives interested in neonatal kidney health to address these gaps. Therefore, the investigators are conducting a second, modified iteration of this study entitled "AWAKEN 2.0". AWAKEN 2.0 will be a multi-center multi-national retrospective analysis utilizing similar methodology to the AWAKEN study.
Immediate release (IR) tacrolimus peaks in the first two hours after administration. These peak levels are influenced by CYP3A5 expression with expressors requiring higher total daily doses with higher peak levels compared to non-expressors. Tacrolimus XR (Envarsus) is a once daily formulation with delayed absorption and lower peak levels while maintaining similar trough levels as seen with IR tacrolimus. A randomized trial of conversion from IR tacrolimus to tacrolimus XR in kidney transplant recipients have shown similar efficacy and adverse events between the two groups but no improvement in estimated GFR. However, urinary biomarkers of acute kidney injury associated with changes in tacrolimus dosing may be more sensitive then serum creatinine. The objective of this study is to assess renal tubular injury in heart transplant recipients who are converted from immediate release to tacrolimus XR. The hypothesis is that the delayed absorption and lower peak levels of tacrolimus XR will lead to less tubular injury and improved renal function without increased risk to the heart allograft.
Multi-center randomized trial to assess the safety and performance of low-frequency therapeutic ultrasound for maintaining renal function after contrast exposure.
This is a Phase 1b, single-center, dose-escalating study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamic effect of RBT-1 in healthy volunteers and in subjects with Stage 3-4 CKD.
Acute kidney injury (AKI), or worsening kidney function, is a common complication after liver transplantation (20-90% in published studies). Patients who experience AKI after liver transplantation have higher mortality, increased graft loss, longer hospital and intensive care unit stays, and more progression to chronic kidney disease compared with those who do not. In this study, half of the participants will have their body temperature cooled to slightly lower than normal (mild hypothermia) for a portion of the liver transplant operation, while the other half will have their body temperature maintained at normal. The study will evaluate if mild hypothermia protects from AKI during liver transplantation.
In pediatric kidney transplant patients, rejection, medication toxicity and ischemia cause early and chronic renal allograft injury, which reduces graft lifespan and patient survival. Early detection of injury would facilitate prevention and treatment. The gold standard surveillance biopsy has limitations including delayed discovery of injury. No noninvasive test identifies graft injury before it is clinically apparent. This project's goal is to develop a novel early marker of subclinical graft injury to facilitate prompt recognition and treatment.
This parallel-group, randomized, placebo-controlled study will examine the incidence and severity of acute kidney injury (AKI) in patients with chronic kidney disease (CKD) stage III/IV following an i.v. injection of iso-osmolar iodinated contrast material iodixanol (Visipaque™ Injection 320 mgI/mL), as compared with patients who received saline and underwent a non-enhanced CT (NECT) and duplex ultrasound (US) during their scheduled post-EVAR surveillance imaging.
Patients with sickle cell disease may be at risk for acute kidney injury (AKI)during sickle cell crisis (pain or acute chest syndrome). This study will evaluate the role of hemolysis during SCD crisis on the development of AKI and the role for monitoring urine biomarkers during an admission for crisis and during well clinic follow-up.
The investigators will conduct a randomized controlled trial that aims to compare the incidence of contrast-induced nephropathy between transradial- and transfemoral-access cardiac catheterization.
In the last decade, transcatheter aortic valve replacement (TAVR) has become an increasingly utilized alternative procedure for replacing a stenotic aortic valve. This study collects clinical information, DNA, blood and urine samples (throughout procedural hospitalization) in order to investigate the incidence of acute kidney injury (AKI) in patients undergoing TAVR and to identify key clinical and procedural predictors of AKI. This study seeks to identify blood and urine biomarkers that can be used for early detection of AKI around the time of the procedure. The study seeks to assess for novel genetic variants associated with development of AKI after TAVR. Finally the study seeks to assess for novel genetic variants and biomarkers that are associated with adverse cardiovascular events after TAVR and to further explore how these events may inter-relate with acute kidney injury.
The objective of this protocol is to investigate the impact of prematurity, with or without associated acute kidney injury (AKI), on the future risk of chronic kidney disease (CKD) by establishing a patient registry and biorepository. Serum and urine samples will be collected serially from premature infants admitted to the neonatal intensive care unit (NICU) at Albert Einstein College of Medicine/Weiler Hospital and subsequently followed in the NICU follow-up and pediatric nephrology ambulatory subspecialty clinics. The biorepository will be linked to a comprehensive clinical database.
Current treatments for ARAS based on restoring blood flow alone have been unsuccessful at recovering kidney function. For this reason we are studying a stem cell product called "mesenchymal stem cells" or MSC. Mesenchymal stem cells (MSC) are grown from a person's own fat tissue (obtained as a fat biopsy) and infused back into the patient's own kidney. This study is also being done to determine if the MSC infusion prior to percutaneous transluminal renal angioplasty with stenting (PTRA) further enhances changes in single kidney blood flow and restoration of kidney function, as well as to assess the relationship between MSC dose and measures of kidney function.
The risk for postoperative acute kidney injury (pAKI), as for any other postoperative complications (PC), comes from a number of interactions between a patient's health before surgery, strength to tolerate surgery and influences on the operating room environment. At this time doctors do not have good tools to predict which patients may be at risk of having this complication. The purpose of this research study is to develop a urine test that can be used to predict the risk for having problems with kidney function after major surgery.
The purpose of this clinical trial is to demonstrate the efficacy and safety of the Osprey Medical CINCOR™ Contrast Removal System.
The purpose of this study is to compare the outcomes of Percutaneous Coronary Intervention (PCI) in patients with chronic kidney disease (CKD) using smaller doses of contrast dye that are validated as being at low risk of causing injury to the kidneys, with the larger doses that are traditionally used contemporary practice.
Black and Hispanic people face higher risks of chronic kidney disease (CKD) but have unequal access to the highest-quality kidney care. Black adults with CKD face 1.5 times higher hospitalization risks than non-Black adults with CKD. Once reaching end stage kidney disease (ESKD), Black patients are half as likely to receive a transplant and are often excluded from home dialysis. Structural racism creates complex barriers to optimal CKD care, providing an explanation for these findings. The Penn Medicine IMPaCT Community Health Worker (CHW) program is a rigorously tested approach to employ people from local communities to dismantle structural racism within health care systems and improve outcomes for marginalized patients. This trial will innovate by training CHWs to focus specifically on CKD care for minoritized people. The investigators will also train primary care clinicians caring for CKD patients on how to provide trauma-informed care (TIC). The first aim is to determine the feasibility, acceptability, and reach of a clinic-level TIC training to address the needs and concerns of Black and other minoritized patients. The second aim will be to conduct a three arm trial comparing individuals in usual care to individuals randomized to either our tailored CHW intervention in conjunction with clinic-level TIC training or to clinic-level TIC intervention only. The investigators will examine whether patients in the intervention arms have greater improvements in quality of life (primary). The investigators will also explore the impact of the interventions on patient activation, hospitalizations, and ESKD treatment preferences.
Long-term graft failure rates continue to be unacceptably high despite the development of immunosuppressive drugs, underscoring the unmet need for robust prognostic biomarkers of allograft injury and failure. While rates of acute rejection (AR) continue to decrease, it remains the strongest predictor of long-term allograft survival, and so having a better understanding of factors predicting AR may contribute to more individualized patient care. Selecting optimum immunosuppressive dosage is another factor in personalizing kidney care. This project will study two areas of individualized kidney care: 1) assessing rejection by surveillance testing utilizing AlloSure, 2) developing an algorithm to select optimum immunosuppressive medication dosage.
To date, little knowledge exists related to the use of hemodialysis (HD) in infants and has been limited to mainly single center studies. The CARPEDIEM (CArdio-Renal PEdiatric Dialysis Emergency Machine) device, which can be used to provide hemodialysis in infants, has been launched in the United States. This study/registry is designed to obtain data on critically ill infants who require HD using the CARPEDIEM device to understand the indications for initiation, best practice in prescribing and performing treatment, expected treatment course, and outcomes of a dedicated infant continuous renal replacement therapy (CRRT) machine.
To assess the performance of the Nova Max Creatinine and eGFR assay in the hands of CLIA-Waived Point-of-Care users in at least three (3) distinct Point-of-Care clinical settings on venous, and capillary blood and compare the performance characteristics to a traceable laboratory reference method (the Siemens EXL creatinine determination). To assess the Ease of Use of the Nova Max Creatinine and eGFR Meter System in the hands of the intended CLIA-Waived Point-of-Care users.
The purpose of this study is to assess the ability of education and outpatient kidney care follow-up in order to improve patient knowledge about acute kidney injury (AKI).
This study evaluates the safety of iodinated contrast medium administered to liver transplant candidates with decreased renal function undergoing coronary CT angiography. Incidence of post-contrast acute kidney injury in liver transplant candidates with decreased renal function and normal renal function will be compared.
This study focuses on the prevalence and identification of kidney disease among participants of the WTC Health Program and the study team are planning to assess kidney disease in a multi-factorial manner. The first aim of this study is to correlate kidney dysfunction with 9/11 exposure, and the study team predicts that exposure to 9/11 is an independent risk factor in kidney disease among the WTC Health Program participants. Secondly, the study team proposes that a well-established WTC-related condition, obstructive sleep apnea (OSA), is independently associated with kidney disease. In addition, the study team believe there is a temporal causative relationship between evidence of kidney disease and the severity of OSA. Finally, the last aim is to further identify and explore potential mechanisms and phenotypes of kidney disease in participants of the WTC Health Programs. Regardless of whether the analyses support or reject these hypotheses, the findings will be of equally great public health importance. Successful completion of the proposed research would address a critical knowledge gap regarding the risk of kidney damage among this group of patients, and would inform future mechanistic studies with the potential to impact prevention.
