NCT06902558
Autosomal Dominant Polycystic Kidney Disease (ADPKD) is the most common genetic cause of kidney disease that causes fluid-filled cysts to develop in the kidneys. The purpose of this study is to assess the safety and efficacy of ABBV-CLS-628 for the treatment of ADPKD in adult participants. ABBV-CLS-628 is an investigational drug being developed for the treatment of ADPKD. Participants are placed in 1 of 4 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 4 chance that participants will be assigned to placebo. Around 240 adult participants with ADPKD will be enrolled at approximately 100 sites worldwide. Participants will receive IntraVenous ABBV-CLS-628 or placebo every 4 weeks for 92 weeks. Participants will be followed for up to 15 weeks. There may be higher treatment burden for participants in this trial compared to their standard of care . Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
NCT05190744
The purpose of this research is to study the effectiveness and safety of the medication PB in slowing the frequent urination related to tolvaptan as long-term treatment of Autosomal Dominant Polycystic Kidney Disease (ADPKD), or frequent urination related to inherited nephrogenic diabetes insipidus as an inherited condition or as an acquired condition from prior treatment with lithium.
NCT03901521
This study will analyze the germline and somatic mutations underlying the development of ADPKD in order to better understand the genetic mechanism responsible for the cystic transformation. Once identified, these mutations could help us understand better the mechanism leading to the development of this disease and may explain at least in part the phenotypic variability.
NCT07282821
Autosomal dominant polycystic kidney disease (ADPKD), the most commonly inherited kidney disease, is characterized by the development of cysts in the kidney that impair function. Of those affected, half will progress to end-stage kidney disease by age 60, requiring dialysis or kidney transplant. To date, no effective and safe therapies exist for this deadly disease. Tolvaptan (Tol), the only FDA-approved drug for treatment of ADPKD, has some benefit in slowing kidney disease progression, but Tol causes frequent urination and thirst and also injures the liver in a small number of patients. The investigators' goal, therefore, is to develop new strategies to treat ADPKD that are safe and tolerable. The development of cysts in ADPKD patients results from two main cellular processes. The first is cell growth with an increase in the number of kidney cells that make up the outer surface of the cyst. The second is an increase in fluid secretion into the cysts that develop. The investigators have shown that an enzyme, AMP-activated protein kinase (AMPK), when activated can inhibit both of those processes. Moreover, genetic mutations that cause ADPKD may alter the energy metabolism of the cell, which in turn inhibits AMPK activity. Bempedoic acid (BA), a medication that is FDA-approved for the treatment of individuals with high cholesterol and has a good safety record, activates AMPK. In addition to activating AMPK, BA inhibits a second enzyme called ATP-citrate lyase (ACLY), which is involved in cholesterol synthesis. ACLY has received growing attention as a novel target for cancer treatment. ACLY inhibition blocks increases of cell numbers by inhibiting the lipid synthesis that is required for creation of new cell membranes. This study will test whether targeting these pathways through treatment with BA will help reverse dysfunctional metabolism in individuals with ADPKD and slow disease progression. The investigators will test this using a phase 2 clinical trial in which 120 individuals with rapidly progressive ADPKD and an estimated glomerular filtration rate of 35 or greater will be treated with either BA or placebo (inactive look-alike pill) for two years. Participants on or off a stable dose of Tol will be included in the study. Participants will be recruited from the U. of Vermont, U. of Maryland, and Tufts University, which have active PKD clinics and are recognized by the PKD Foundation as Centers of Excellence. Through follow-up visits and lab work, the investigators will assess the safety and tolerability of BA in the participants as the primary outcomes. The secondary goals are to assess preliminary efficacy and effects of BA on quality of life in study participants. The growth of cysts results in increased volume or size of the kidneys and liver. Total and cyst volumes of the kidney and liver and visceral abdominal fat content via magnetic resonance imaging (MRI) will be measured to gauge the effectiveness of this drug. The investigators also predict that proteins and small molecules involved in regulating cell energy metabolism, inflammation, and injury, as well as proteins directly involved in AMPK and ACLY function, will be altered in ADPKD patients. Levels of these proteins and small molecules may then subsequently change with BA therapy. Exploratory, mechanistic goals of this study are to identify prognostic and predictive urinary biomarkers in study participants. Successful completion of this study would have a significant impact on individuals with ADPKD by laying the groundwork for a new treatment strategy as well as by providing a new way to help guide treatment decisions. In summary, the goals of this phase 2 randomized, double-blind, placebo-controlled clinical trial are to test the safety, tolerability and preliminary efficacy of the drug bempedoic acid, FDA-approved to lower cholesterol, when used in ADPKD patients.
NCT07260071
The goal of this project is to measure the prevalence of Autosomal Dominant Polycystic Kidney Disease (ADPKD) and hypertension in the general population of children and young people at risk of ADPKD, using magnetic resonance imaging (MRI) for rapid diagnosis alongside genetic testing. The main question it aims to answer is: What is the prevalence of hypertension in a population sample of adolescents with ADPKD? Participants will have the following measurements performed: * Height and weight. * Blood pressure. * Non-invasive measurement of arterial stiffness. * Cardiac and renal MRI. * Blood sample. * Genetic testing.

NCT03970018
Autosomal dominant polycystic kidney disease (ADPKD) is first genetic kidney disease and fourth etiology of end stage renal disease in the world. Peritoneal dialysis is underuse in this population. Indeed in this pathology, behind big kidneys and big liver, a hyper pressure is feared with technical failure. The lack of abdominal space could generate increase of peritoneal pressure. Hyper pressure is already known to be a risk factor of technical failure and over mortality in peritoneal dialysis patients (all nephropathies included). It depends on body mass index and body surface modulating injected volume for each patient. Anticipate peritoneal pressure in this population ADPKD could be an important information for distinguish those who can use peritoneal dialysis without fear and those at risk of technical failure. The primary objective is to create and validate prediction score for intra-peritoneal pressure, in peritoneal dialysis for ADPKD patients thanks to clinical and radiological values. The secondary objectives are to study the association between intra-peritoneal pressure and patient's outcome (global survival and technical survival). Retrospective, multicentric, national, cohort study will be performed. For the first step (score creation): ADPKD patients starting peritoneal dialysis for end stage renal failure between 01/01/2010 and 31/12/2015 with tomodensitometry between one year before beginning and one year after were included. For the second step (score validation): ADPKD patients starting peritoneal dialysis for end stage renal failure between 01/01/2016 and 31/12/2017 with tomodensitometry between one year before beginning and one year after were included.
