Treat Autosomal Dominant Polycystic Kidney Disease With Oral Ketone Ester?

ADKETONE
Start date: November 2023
Phase: Phase 2
Study type: Interventional

The investigators are running a study to see if a special drink, called a "ketone ester", can help people with a type of kidney disease named "Autosomal Dominant Polycystic Kidney Disease" or ADPKD for short. The investigators want to find out: If it's easy for patients to take this drink every day for about 2 months. If it's safe and doesn't cause any problems. If it makes a difference in the size and function of the kidneys. Who can join? People between 16 to 70 years old who have ADPKD. Those with a certain amount of kidney size and function. People who haven't been on specific diets or lost a lot of weight recently. Women who are not breastfeeding and are using birth control. People with a body weight that is not too low or too high. Who cannot join? People who've been on a high-fat diet or skipped meals for a while recently. Those with other health conditions like diabetes or certain metabolic issues. Anyone who has a problem with getting an MRI scan. If participants are in another medical study right now. The study will happen in two Belgian hospitals and is supported by the UZ Brussel's nephrology department. The investigators hope to include 20 people and start in November 2023.

Genetic Testing in Autosomal Dominant Polycystic Kidney Disease

Start date: June 1, 2023
Phase:
Study type: Observational

Individuals with a diagnosis of autosomal dominant polycystic kidney disease (ADPKD) often have a family history of the condition although up to 10-15% of cases are sporadic mutations. The investigators recently conducted an analysis of the investigators clinic population to determine percentages of individuals who have undergone kidney imaging and genetic testing and determined total numbers of patients eligible for tolvaptan and those currently active on tolvaptan. The study team found large racial discrepancies in usage of tolvaptan and found that more patients are eligible for tolvaptan than are currently taking the medication. Reasons for this are often due to patient perception about the medication rather than treatment failure. There is a strong medical need to understand reasons for underuse of this critical medication in this population. Among those with genetic testing, the study team found large disparities in ethnic background between individuals offered genetic testing who accept versus decline testing. The study team also found that those who choose to pursue genetic testing are more likely to have no family history of the condition, presumably because the diagnosis is more "surprising" to them and thus desire for verification by genetic testing, if possible, is greater. However, it is known that genetic testing can be an important component of understanding of disease biology in all patients with ADPKD, while also providing important clinical information in some cases as individuals prepare for living donor transplantation or family planning. The investigators seek to understand barriers to use of tolvaptan and genetic testing among individuals in the clinic population and their relatives across a wide range of racial and ethnic backgrounds. The investigators hypothesize that anxiety about genetic conditions in particular is a barrier to accepting testing. The investigators seek to understand the mental health aspects of the diagnosis of ADPKD. They will also evaluate changes in symptoms compared to pre-treatment after initiation of tolvaptan in eligible individuals using qualitative techniques. In so doing, the study team hope to improve care for current patients and also to expand the pool of the clinic population to include newly diagnosed family members ideally at early stages of disease.

HYDROchlorothiazide to PROTECT Polycystic Kidney Disease Patients and Improve Their Quality of Life

HYDRO-PROTECT
Start date: March 2024
Phase: Phase 3
Study type: Interventional

Autosomal dominant polycystic kidney disease (ADPKD) is characterized by progressive formation of renal cysts which ultimately lead to a loss of renal function. Tolvaptan (a V2R antagonist) is currently the only effective treatment for preserving renal function in ADPKD. However, side-effects such as polyuria limit its tolerability and thereby the therapeutic potential. This study will test whether co-administration with hydochlorothiazide can improve V2RA efficacy (slowing kidney function decline) and tolerability (quality of life) in ADPKD. Approximately 300 patients will be enrolled.

NCT ID: NCT05014178 Recruiting - Clinical trials for Chronic Kidney Disease

Kidney Sodium Functional Imaging

Start date: September 16, 2021
Phase:
Study type: Observational

The corticomedullary gradient is largely responsible for developing the gradients that are needed to concentrate urine (more solutes and less water). The ability of the kidneys to produce concentrated urine is a major determinant of the ability to survive the warm weather. When temperatures are high, we lose water through sweat, and so the kidneys retain water to maintain fluidity in the blood. The maintenance of a sodium (salt) gradient is required for urine concentration because increased medullary sodium concentration increases the reabsorption of water into the kidney, to be redistributed in the blood. The purpose of this study is to know if the corticomedullary gradient is altered in patients across a wide spectrum of kidney disease using sodium Magnetic Resonance Imaging (MRI), a machine that takes pictures and measures the salt content in the kidneys. 23Na kidney MRI, will provide functional MR of the kidney as a non-invasive tool to describe medullary function to improve management of chronic and kidney disease.

Ketogenic Dietary Interventions in Autosomal Dominant Polycystic Kidney Disease (ADPKD)

Keto-ADPKD
Start date: January 10, 2021
Phase: N/A
Study type: Interventional

A mild reduction in food intake significantly inhibits renal cyst growth in mouse models of ADPKD. The underlying mechanism was unknown at the time. Recently published data show that the beneficial effect is not due to caloric restriction per se but due to the induction of the state of ketosis. Dietary interventions leading to ketosis profoundly inhibited renal cyst growth in rodent models of PKD. In addition, acute fasting led to rapid regression of renal cystic burden in mouse, rat and feline models of PKD. Due to these compelling effects in a multitude of PKD animal models, and due to the fact that well-established dietary interventions have a tremendous translational potential, KETO-ADPKD will test such interventions regimens in ADPKD patients. Two well-established ketogenic dietary regimens will be tested in comparison to a control group to address the following four questions: 1. Feasibility: Are ketogenic dietary interventions acceptable to ADPKD patients in everyday life? 2. Safety: Are there adverse events of ketogenic dietary interventions in ADPKD patients? 3. Efficacy: Do the dietary interventions reach the metabolic endpoints? Do they have a short-term impact on kidney volume? 4. Which of the two diets is the optimal approach? These questions will be addressed in an exploratory, randomized, open, single center, three-arm dietary intervention study using the following interventions in 21 ADPKD patients per treatment arm: A) Ketogenic diet B) 3-day water fasting C) Control: ad libitum food intake (no diet)

NCT ID: NCT04472624 Completed - ADPKD Clinical Trials

Short Term Induction of Ketosis in PKD

RESET-PKD
Start date: July 1, 2020
Phase: N/A
Study type: Interventional

Recently, it has been shown that ketose-inducing dietary interventions slow disease progression in animal models of polycystic kidney disease (PKD), even when the state of ketosis is only induced for a short period of time. The present study aims to investigate the effects of short term ketosis on total kidney volume (TKV) (and other parameters) in 10 ADPKD-patients with rapidly progressive disease.

Autosomal Dominant Polycystic Kidney Disease (ADPKD) Study

ADPKD
Start date: October 10, 2019
Phase:
Study type: Observational

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.

Wishing to Decrease Aquaresis in ADPKD Patients Treated With a V2Ra; the Effect of Regulating Protein and Salt

WATER
Start date: September 7, 2020
Phase: N/A
Study type: Interventional

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.
