Active clinical trials for "Polycystic Kidney, Autosomal Dominant"

Multicenter trial on the effect of the GnRH analogue leuprorelin on the growth of total liver volume in pre-menopausal women with very severe polycystic liver disease who, despite available therapy, experience growth and are heading for liver transplantation.

This clinical trial will determine whether a daily-caloric restriction-based weight loss intervention can slow kidney growth in adults with autosomal dominant polycystic kidney disease who are overweight or obese. The study will also evaluate changes in abdominal fat by magnetic resonance imaging. Blood and fat samples will provide insight into biological changes that may contribute to any observed benefits of the intervention.

Patients with large hepatic cysts (> 5cm) may develop symptoms. These can be captured with the polycystic liver disease questionnaire (PLD-Q). Treatment of large hepatic cysts consists of aspiration sclerotherapy or laparoscopic fenestration. The safety and efficacy of both procedures has been explored in two recent systematic reviews yet no evident conclusion regarding superiority of either procedure could be drawn. The main objective of the ATLAS trial is to compare laparoscopic fenestration and aspiration sclerotherapy in patients with large symptomatic hepatic cysts on patient-reported outcomes.

RDN-ADPKD is a prospective, randomized (1:1, central randomization), single-center, hypothesis-generating, feasibility study. The purpose of the RDN-ADPKD study is to demonstrate efficacy and document safety of renal denervation (RDN) with the Paradise System in hypertensive patients with ADPKD.

Primary Objectives To assess the safety and tolerability of RGLS8429 To assess the impact of RGLS8429 on ADPKD biomarkers Secondary Objectives To assess the impact of RGLS8429 on height-adjusted total kidney volume (htTKV) To characterize the pharmacokinetic (PK) properties of RGLS8429 To assess the impact of RGLS8429 on renal function

Autosomal dominant polycystic kidney disease (ADPKD) is the most common inherited kidney disease characterized by cystic kidneys and caused by mutations in the polycystic kidney disease and other rare genes. It is associated with salt-sensitive hypertension, which accounts for the majority of morbidity and mortality. About 70% of patients with ADPKD develop hypertension, prior to the onset of kidney function decline. Early onset hypertension, despite its treatment, is independently associated with rapid kidney function decline. The investigators hypothesize that a high-sodium diet in patients with ADPKD is required for the development of vascular stiffness, which precedes hypertension, and that treatment with amiloride reverses this phenomenon.

This study will investigate if a medication (metformin) widely used in the treatment of diabetes could be re-purposed for the treatment of patients with a diagnosis of early stage ADPKD to slow the rate of kidney function decline, reducing morbidity and mortality and improving the quality of life for ADPKD patients.

The investigator proposes a pilot randomized clinical trial to determine the safety and tolerability of empagliflozin in ADPKD patients. To achieve this, the investigator will conduct a 12-month parallel-group, randomized, double-blind, placebo-controlled trial in 50 ADPKD patients with an eGFR 30-90 mL/min/1.73m2.

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.

Polycystic Kidney Disease (PKD) is the most common genetic disease leading to End Stage Kidney Disease (ESKD), affecting between 1 in 500-1000 individuals from every ethnic group. The autosomal dominant (ADPKD) form arises from a two-hit downregulation of proteins encoded by either PKD1 or PKD2. Although many potential therapies have been studied to slow progression of ADPKD, none to date have been proven to be both safe and effective in slowing disease progression. Cholesterol-lowering agents called statins have shown promise in the treatment of younger ADPKD patients, reducing inflammation and progression as assessed by kidney growth, but their utility appears to be limited in older populations and those with more advanced chronic kidney disease (CKD). Recent evidence suggests that acidosis, as often seen in patients with worsening CKD and which may enhance CKD progression, limits the effectiveness of statins and enhances their potential toxicity. The investigators thus hypothesize that correction of acidosis along with statin treatment will be a safe and effective therapeutic regimen to slow CKD progression in the adult ADPKD population and improve overall quality of life in these patients. To test this hypothesis, the investigators will conduct a pilot open-label randomized clinical trial in ADPKD patients with estimated GFR >45 min (Stage 1-3a CKD) comparing three treatment groups: control, atorvastatin (20 mg po qd), and atorvastatin plus sodium bicarbonate tablets (upto 1800mg po total daily dose) over one year. At the beginning of the study, the investigators will determine the genotype of the trial participants. During the study period, through study visits along with serial blood draws and urinary measurements, the investigators will evaluate safety and tolerability of these treatment regimens, follow renal function and investigate the role of these treatments on acidosis, inflammatory and metabolic biomarkers in patients enrolled at an outpatient facility. Serial follow-up imaging study will also be done in selected patients. This study will establish the framework for larger clinical trials in ADPKD. Moreover, if the results of this study suggest safety/tolerability or potential benefits of statins and alkali therapy in this ADPKD population, the investigators will seek extramural funding for a larger clinical trial to test this therapeutic strategy in ADPKD.
