Filter by:This is an exploratory, randomized, double-blind, placebo-controlled, parallel group, multicenter, proof of concept study (Phase 2a), evaluating orally administered GLPG2737 for a double-blind (DB) treatment period of 52 weeks and 4 weeks of follow up as well as an open-label extension (OLE) treatment period of 52 weeks and 4 weeks of follow-up, in subjects with rapidly progressing ADPKD.
Primary Objective • To assess the dose response relationship between RGLS4326 and ADPKD biomarkers Secondary Objectives - To characterize the pharmacokinetic (PK) properties of RGLS4326 in plasma and urine - To assess the safety and tolerability of RGLS4326
The proposed research will determine the feasibility of a time restricted feeding intervention,a fasting regimen that restricts eating to a feeding window (8 hrs/day) for 1 year in adults with autosomal dominant polycystic kidney disease (ADPKD) who are overweight or obese. The study will provide valuable information on the intervention in terms of safety, adherence, acceptability, and tolerability. Last, this pilot trial will provide initial insight into biological changes including abdominal adiposity, changes in kidney growth and function, and markers of biological pathways related to the intervention.
Autosomal dominant polycystic kidney disease (ADPKD) is the most common monogenic cause of end-stage kidney disease (ESKD). The disorder is characterized by development and continued growth of multiple cysts requiring renal replacement therapy in 50% of patients by age 60 years. However, ADPKD is also a complex metabolic disorder defined by insulin resistance (IR) and mitochondrial dysfunction which may be causally related to cyst expansion, kidney function decline and contribute to reduced life expectancy. Renal hypoxia, stemming from a potential metabolic mismatch between increased renal energy expenditure and impaired substrate utilization, is proposed as a novel unifying early pathway in the development and expansion of renal cysts in ADPKD. By examining the interplay between renal O2 consumption and energy utilization in young adults with and without ADPKD, the investigators hope to identify novel therapeutic targets to impede development of cyst expansion in future trials. The investigators propose to address the specific aims in a cross-sectional study with 20 adults with ADPKD (50% female, ages 18-40 years). Comparative data will be provided from healthy adults from an ongoing study with similar study design and methods (CROCODILE Study: Control of Renal Oxygen Consumption, Mitochondrial Dysfunction, and Insulin Resistance). For this protocol, participants will complete a one day study visit at Children's Hospital Colorado. Patients will undergo a dual energy x-ray absorptiometry (DXA) to assess body composition, and a 11C-acetate positron emission tomography (PET/CT) scan to quantify renal O2 consumption. After the PET/CT, participants will undergo a hyperinsulinemic-euglycemic clamp while fasting to quantify insulin sensitivity. Glomerular Filtration Rate (GFR) and Effective Renal Plasma Flow (ERPF) will be measured by iohexol and PAH clearances during the hyperinsulinemic-euglycemic clamp.
The ability to concentrate and dilute urine is primarily regulated via vasopressin (AVP) dependent Aquaporin-2 water channels (AQP2 channels) in the kidney's collecting duct. Autosomal dominant polycystic kidney disease (ADPKD) is a common genetic disorder, characterized by the formation of cyst in the kidneys, causing gradual renal function-loss. Previous studies indicate that ADPKD patients have decreased urine concentration, higher plasma osmolality, and plasma AVP levels compared to healthy controls. Previous studies also indicate that ADPKD patients' dysregulated AVP is an important factor for the pathogenesis and progression of the disease. It is unclear whether ADPKD patients' ability to concentrate and dilute urine are different from those of other cause of chronic renal disease to the same degree. It is also unclear, what mechanisms cause the decreased ability to concentrate and dilute urine in chronic renal disease patients. The purpose of this trial is to investigate the difference in renal function during concentration and dilution test in a case-control, randomized, cross-examination study with ADKPD patients or other cause of chronic renal disease compared to healthy volunteers.
The purpose of this study is to characterize oxidative stress and the Nrf2 antioxidant response in early stages of Autosomal Dominant Polycystic Kidney Disease (ADPKD), while identifying candidate biomarkers.
Autosomal Dominant Polycystic Kidney Disease (ADPKD) is the most common genetic cause of renal failure. For several decades, ADPKD was regarded as an adult-onset disease. In the last decade, it has become more widely appreciated that the disease course begins in childhood. However, evidence-based guidelines on how to manage and approach children diagnosed with or at-risk for of ADPKD are lacking. Overall, there is insufficient data on the clinical course during childhood. The study intends to get more information on Autosomal Dominant Polycystic Kidney Disease (ADPKD) and other hepato/renal fibrocystic diseases. Additionally, the study intends to expand web-based resources so anyone can learn about ADPKD or other hepato/renal fibrocystic diseases. Individuals diagnosed with the dominant form of a hepato/renal fibrocystic condition are invited to be in the study.
This study evaluates the effect of regulating salt and protein intake on urinevolume in patients with ADPKD treated with a vasopressine V2 receptor antagonist (V2RA). The investigators hypothesize that changing sodium and protein intake will reduce V2RA-induced polyuria.
This is an one-year open-label study to determine treatment efficacy and feasibility of a trial that uses open-label interventions in ADPKD patients.
This is a Phase 3, open-label, repeat-dose study designed to assess liver safety, non-liver safety, and efficacy of lixivaptan in participants who previously experienced liver chemistry test abnormalities while treated with tolvaptan and were permanently discontinued from the drug for that reason. Up to 50 eligible participants will be enrolled and treated with lixivaptan for 52 weeks following titration to an optimal dose.
