5,369 Clinical Trials for Various Conditions
The overarching goal of this project is to refine and adapt previous work on the NAVIGATE-Kidney project for Latinx with CKD. The investigators hypothesize that the multilevel NAVIGATE-Kidney program intervention will reduce the rate of central venous catheter use at KRT start (primary outcome), increase the rate of optimal KRT starts (secondary outcome), increase patient activation, and reduce decisional conflict (patient-centered outcomes) for Latinx with advanced CKD. The project will have four (4) aims.
During partial nephrectomy surgery, efforts at minimizing ischemia while maximizing renal parenchymal volume are desirable to preserve renal function1,2. Not only clamping of the hilum but the renorrhaphy portion of the procedure also can have a significant negative impact on renal function3-5. It is possible to perform this procedure without clamping the hilum and also without formal renorrhaphy. However robust prospective formal evaluation of safety, risks, and potential benefits and whether or not the technique can be employed in a generalized fashion has not been studied. Demonstration of safety and generalizability may open a whole new avenue of approaching nephron sparing and renal function sparing kidney surgery and decrease potential risks for long term kidney disease in patients with renal masses. This study will investigate the safety, efficacy, and generalizability of the use of clampless, sutureless partial nephrectomy in the treatment of renal cell carcinoma.
The central hypothesis of this research study is that perioperative administration of the proton pump inhibitor (PPI) pantoprazole could reduce the development of acute kidney injury (AKI) following cardiac surgery by activation molecular pathways for kidney protection. The investigators propose a single-center, randomized, controlled, single-blinded trial to determine whether perioperative intravenous administration of pantoprazole will reduce the incidence of AKI, some molecules that can be detected the urine, and major adverse kidney events (MAKE) at day 30 postoperatively, compared to famotidine after cardiac surgery. The specific aims of the study will be achieved by randomizing a group of 400 patients to receive pantoprazole (study) or famotidine (control) for 3 days perioperatively. Our study population will include any adult patients (aged over 18 years) scheduled for cardiac surgery requiring a cardiopulmonary bypass machine.
To evaluate progression of metastatic renal cell carcinoma from the initiation of PULSAR radiotherapy in combination with IMSA101 injectable onward.
This phase II trial compares the safety and effectiveness of 89Zr-DFO-GmAb positron emission tomography (PET)/computed tomography (CT) compared to contrast-enhanced CT after surgery in detecting clear cell renal cell cancer that has come back (recurrent). For some patients, the risk of recurrence after surgery remains high. Conventional CT methods, such as contrast-enhanced CT, may not detect small volume or micrometastatic disease. PET/CT with radiotracers, such as 89Zr-DFO-GmAb, may improve detection of tumor cells. Girentuximab (GmAb), a monoclonal antibody, is tagged with zirconium-89, a radioactive atom (which is also known as an isotope). The zirconium-89 (89Zr) isotope is attached to girentuximab with desferrioxamine (DFO) and this combined product is called 89Zr-DFO-girentuximab. 89Zr-DFO-girentuximab attaches itself to a protein on the surface of clear cell renal cell tumor cells called CAIX. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of tracer, in the case of this research, 89Zr-DFO-GmAb. Because some cancers, including clear cell renal cell cancer, take up 89Zr-DFO-GmAb it can be seen with PET. CT utilizes x-rays that traverse body from the outside. CT images provide an exact outline of organs and potential inflammatory tissue where it occurs in patient's body. Using contrast agents with CT scan to enhance the images (contrast-enhanced CT) is standard of care imaging. 89Zr-DFO-GmAb PET/CT may be safe and effective compared to contrast-enhanced CT in detecting recurrent clear cell renal cell cancer after surgery.
This is a study to collect information to assess if transporting hard-to-place (HTP) donor kidneys to a central preservation and assessment facility with dedicated organ assessment capabilities increases allocation success to transplant hospitals.
This study will evaluate the safety and efficacy of AT-1501 compared with tacrolimus in patients undergoing kidney transplantation.
This is a human subject research study conducted in patients undergoing dialysis treatment with darbepoetin alfa at Intermountain Utah Dialysis and Intermountain Medical Center Dialysis Services. The purpose is to test a dose recommendation algorithm that may reduce hemoglobin variability and drug cost.
The goal of this study is to assess the physician and patient experience of radio frequency (RF) track cautery in patients undergoing needle biopsy of the liver, kidney, or spleen who have one or more risk factors for biopsy-related bleeding. RF track cautery involves inserting a bipolar electrode through the same introducer needle used for the biopsy, and heating the tissues along the path of the biopsy needle to prevent bleeding. This study primarily aims to assess the operator and patient experience during the use of track cautery. Secondary aims are to assess the technical success rate and procedure adverse events. Participants who enroll in the study will undergo track cautery as part of their clinically indicated liver, kidney, or spleen biopsy. After the procedure, they will fill out a brief survey asking about their experience during the procedure. Physician operators who perform track cautery as part of the study will also fill out a survey after each procedure asking about their experience using this technique.
The goal of this study is to better understand the effects of a sodium-glucose transport protein 2 inhibitor, dapagliflozin, added on to standard of care on heart and lung function and circulating metabolites (substances created when our bodies break down food, drugs, or its own tissues) in patients with chronic kidney disease.
The purpose of the study is to determine how much a persons kidney function recovers after receiving a simultaneous liver kidney transplant. The investigators will be contacting patients with kidney dysfunction with estimated GFR between 25 and 40 (not on dialysis treatment) who are listed to receive a simultaneous liver kidney (SLK) transplant to look at this function recovery. The investigators hope to develop a criteria based on GFR measurement, kidney function calculations from native kidneys vs transplanted kidney and compare the contributions, and correlate with estimated GFR on basic metabolic panel (BMP: a blood test) to predict higher chances of recovery of native kidney function.
The objective of the proposed study it to perform a pilot clinical trial both to establish feasibility of applying a computational, augmented intelligence based approach, Phenotypic Precision Medicine (PPM), to optimizing combination drug therapy and to gather preliminary data to support a larger fully powered multi-center clinical trial. The key rationale for this clinical selection is that we have the technical, biological, and medical expertise in this disease, a wealth of experience in the use of PPM in both in vitro and the clinical setting, and a robust and integrated transplant program with a well-functioning clinical trial infrastructure.
This is a randomized, double-blind, placebo-controlled trial in de novo kidney transplant patients to determine if the addition of fingolimod (brand name Gilenya®, candidate name- FTY720) on the background of standard immunosuppression will prevent expansion of the interstitial compartment of the transplanted kidney. Interstitial expansion is the precursor of interstitial fibrosis and graft loss. The study will test the hypothesis that abgrogating the fibrogenic effects of both the RhoA and mTOR pathways with fingolimod will reduce structural damage in transplanted kidneys and possible subsequent transplant failure.
Despite the reduction in acute rejection episodes in renal transplant patients due to modern immunosuppression, proportionate improvements in long-term allograft survival have not been achieved. Virtually any disease or injury affecting renal allografts can culminate in irreversible injury of tubular epithelial cells and the development of interstitial fibrosis and tubular atrophy (IFTA). Renal allograft fibrosis drives chronic kidney disease (CKD) progression, predicts allograft failure and is associated with increased patient mortality. Other prognostic and/or actionable diagnoses described by the pathologic Banff scheme, such as inflammation, often co-exist and contribute to IFTA. Immune cell infiltration within allografts and within areas of IFTA (i-IFTA) can drive progressive kidney injury, fibrosis and worsened outcome. Pathology is the reference standard for IFTA; however, allograft biopsy has many well-known limitations and is not an ideal method for monitoring patients during trials of new therapies aimed at improving allograft survival. There is an urgent and unmet need for non-invasive assessment of renal allograft IFTA. Multiparametric MRI (mpMRI), including relaxometry \[the spin-lock relaxation time T1ρ, a marker of interaction of water with macromolecules in tissues; the spin-lattice relaxation time T1, a marker of interstitial edema and collagen volume fraction)\] and advanced diffusion \[intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI), a marker of diffusion and perfusion\] provides insight into renal structure and function. Validation of advanced MRI methods as markers of renal allograft IFTA would be of major clinical significance to enable early detection, assess the efficacy of novel anti-fibrotic agents, and provide longitudinal disease monitoring. The study team has established proof-of-concept in renal allografts with stable function and IFTA without confounding rejection or infection that mpMRI techniques are feasible for measuring fibrosis, especially using the combination of T1 and DWI. The study has established that urinary biomarkers for renal allograft fibrosis are also promising and have been validated against pathology in initial studies. In this proposal, the researchers will develop a short, non-contrast multiparametric MRI (mpMRI) protocol, consisting of advanced relaxometry (T1 mapping and T1ρ) and advanced diffusion weighted imaging (IVIM-DWI) to accurately detect and stage allograft fibrosis, taking into account confounding Banff variables of inflammation and tested against biopsy. The researchers will also assess the added value of urinary biomarkers of IFTA and if successful, this study will benefit a large population of patients with renal allograft fibrosis in the United States, enabling early diagnosis, optimized treatment planning, prognostication and longitudinal disease monitoring.
This study will evaluate the safety, PK, and efficacy of AT 1501 in patients undergoing kidney transplantation.
This is first in human study of DFF332, a small molecule that targets a protein called HIF2α. By acting on HIF2α, DFF332 may be able to stop the growth of certain types of cancer. DFF332 will be tested at different doses as single agent and in combination with Everolimus (RAD001, an mTOR inhibitor), and also in combination with Spartalizumab (PDR001, an anti-PD1) plus Taminadenant (NIR178, an adenosine A2A receptor antagonist), in patients with advanced clear cell renal cell carcinoma and other malignancies with HIF stabilizing mutations.
The purpose of this study is to assess the safety and tolerability of allogeneic mesenchymal stem / stromal cell therapy in individuals with chronic kidney disease.
To support advances in the understanding of pathophysiology and therapies of kidney diseases by creating a BioBank of kidney tissue, DNA, plasma, and urine from patients with kidney diseases.
Medication non-adherence is a major problem in kidney transplant recipients; young people 12-24 years of age are at particularly high risk for non-adherence and graft failure compared to young children and adults. Given that poor medication contributes greatly to graft failure, clinically feasible and effective interventions are urgently needed to improve adherence, survival, and quality of life in this population. The broad aim of this prospective, 3-stage, sequential study is to improve medication adherence in adolescent kidney transplant recipients by: 1) adapting the successful Teen Adherence in Kidney transplant Effectiveness of Intervention Trial (TAKE-IT) intervention for use in 'real world' clinical care, 2) designing and testing a new portable electronic pillbox and companion tracking website interface, and 3) preliminary testing of the adapted intervention.
The goals of this study are to improve the ability of pediatric patients and their caregivers to select surgical treatment options for kidney stones and to enable urologists to use techniques that result in the best outcomes for these surgeries.
This is a multicenter, randomized, double-blinded, controlled Phase 3 trial of cabozantinib in combination with nivolumab and ipilimumab versus nivolumab and ipilimumab in combination with matched placebo. Approximately 840 eligible subjects with intermediate- or poor-risk advanced or metastatic RCC by IMDC criteria will be randomized in a 1:1 ratio at approximately 180 sites.
The primary purpose of this study is to evaluate the pulse wave velocity and vascular compliance measurements at the beginning and the end of the study while the participants are taking either extended release tacrolimus tablets (known by brand name Envarsus XR®, and also referred to as LCPT in this study) given once-daily each morning after transplantation or immediate release tacrolimus capsules (also known by brand name Prograf® or abbreviation IR-TAC in this study) that are administered twice-daily 12 hours apart after kidney transplantation. Pulse wave velocity and vascular compliance measurements are two non-invasive tests that are used to evaluate how well the blood vessels adapt to each heartbeat. The secondary purpose is to look at the effectiveness and safety of LCPT given once-daily compared to IR-TAC given twice-daily 12 hours apart after kidney transplantation.
This is an open-label Phase 2 study which will evaluate the efficacy and safety of belzutifan in combination with cabozantinib in participants with advanced ccRCC. Belzutifan and cabozantinib will be administered orally once daily.
Kidney disease patients have a variety of bone disorders that result in bone loss and fractures. The mechanisms of these bone disorders are not clear but may be related to abnormal modification of a bone protein known as collagen. Therefore, the investigators are conducting this research study to identify underlying mechanisms that are responsible for the disruption of bone collagen and determining whether the abnormal bone collagen impairs bone strength. The investigators intend to identify these mechanisms through studying relationships between kidney disease and bone strength via bone imaging, bone biopsy and non-invasive measures from blood and skin.
The primary objective is to compare the effect of treatment with an immediate-release tacrolimus to an extended-release tacrolimus (i.e., Envarsus® XR) immunosuppressive regimen on cognitive and motor function in kidney transplant recipients
In this study, Investigators will conduct a prospective cohort study of dialysis patients by collecting research-quality information on patient characteristics, comorbid diseases and laboratory markers used in routine practice, as well as novel biochemical markers and genetic data. Investigators will utilize data from the cohort to test the independent relationship between biochemical and genetic markers and Fabry disease and other rare diseases.
This study will enroll individuals who have end stage renal disease and who are undergoing a solitary kidney transplant. This study is investigating/evaluating the safety and effectiveness of collecting, expanding and infusing a specific certain type of immune cell known as Regulatory T cells (Treg cells) to renal transplant recipients who are using Zortress (Everolimus) as immunosuppressive therapy. Treg cells, once they have been expanded in the laboratory to help prevent kidney rejection. Treg cells are collected from a participant's blood through a procedure called apheresis. Treg cells are a type of white blood cells that are able to suppress the activity of other immune cells responsible for organ rejection. The investigator plans to enroll 12 participants at the University of Kentucky.
