Active clinical trials for "Polycystic Kidney, Autosomal Dominant"

DRINK is an open-label randomised controlled feasibility trial of high versus ad libitum water intake in ADPKD.

To evaluate the safety and therapeutic effectiveness of tolvaptan when administered to slow the progression of cyst development and renal function insufficiency in adult Korean patients diagnosed with rapidly progressive ADPKD who have chronic kidney disease (CKD) stages 1-3 at initiation of treatment.

The investigators multicenter randomized open-labelled study will investigate the efficacy of an everolimus based immunosuppression in reducing total native kidney volume in kidney recipients with autosomal dominant polycystic kidney disease compared to a calcineurin inhibitor-based immunosuppression.

Rationale: Polycystic liver disease (PLD) is a rare disorder characterized by >20 fluid-filled hepatic cysts. Polycystic livers are present in the combination with renal cysts as a manifestation of autosomal dominant polycystic kidney disease (ADPKD), or isolated in the absence of renal cysts as autosomal dominant polycystic liver disease (ADPLD or PCLD). PLD patients are confronted with symptoms caused by the mass effect of their polycystic liver every day for the rest of their life. There is no standard therapeutic option for symptomatic PLD patients. Current options are fairly invasive or their efficacy is only moderate. Preliminary data in our research lab have shown that ursodeoxycholic acid (UDCA) inhibited the proliferation of polycystic human cholangiocytes in vitro through the normalization of the intracellular calcium levels in cystic cholangiocytes. The investigators also found that daily oral administration of UDCA for 5 months to polycystic kidney disease (PCK) rats, an animal model of ARPKD that spontaneously develops hepato-renal cystogenesis, resulted in inhibition of hepatic cystogenesis. The investigators hypothesize that UDCA is an effective therapeutic tool in reducing liver volume in PLD. Objective: First, to demonstrate whether UDCA-therapy is effective in reducing total liver volume in PLD patients. Second, the investigators want to assess if UDCA modifies quality of life. Finally, the investigators want to assess safety and tolerability. Study design: International, multicenter, randomized, controlled trial Study population: 34 subjects (18 ≤age ≤ 80 years) suffering from symptomatic polycystic liver disease with underlying diagnosis of (PCLD or ADPKD), defined as ≥ 20 liver cysts on CT-scan and liver volume of ≥ 2500. Symptomatic is defined as Eastern Cooperative Oncology Group- Performance Score (ECOG-PS) ≥ 1 and having at least three out of ten PLD symptoms. Intervention: The patients will be randomized (1:1) into two groups. One group of patients will receive 15-20mg/kg/day UDCA for 24 weeks. The other group will receive standard care. Main study endpoint: Proportional change of total liver volume in UDCA treated patients versus non treated patients, as assessed by CT at baseline and 6 months.

The proposed research will determine the effectiveness of blocking aldosterone for improving the health and function of arteries in patients with autosomal dominant polycystic kidney disease (ADPKD). The study also will provide insight into how blocking aldosterone improves artery health by determining the physiological mechanisms (biological reasons) involved. Overall, the proposed research will provide important new scientific evidence upon which physicians can base recommendations to patients with ADPKD to decrease risk of developing cardiovascular diseases.

This purpose of this study is to determine if bosutinib reduces the rate of kidney enlargement in subjects with autosomal dominant polycystic kidney disease (ADPKD) entering the study with a total kidney volume greater than or equal to 750 cc and eGFR greater than or equal to 60 mL/min/1.73m2.

We will enroll 20 patients to evaluate the effectiveness of a new operation known as videothoracoscopic splanchnicectomy (VSPL) for management of chronic kidney pain. This study is being done to test if this procedure is effective in controlling chronic kidney pain.

This study's purpose is to evaluate the long-term safety and efficacy of tolvaptan versus placebo in patients with 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

Patients affected by Autosomal Dominant Polycystic Kidney Disease (ADPKD) need a safe and effective long-term treatment regimen. Unfortunately, there are still no disease-specific treatment for ADPKD approved in the US. A rational step towards identifying such agents is to test therapies that have a proven safety profile with mechanisms of action that can counter the disease progression. The purpose of this study is to investigate whether drinking increased amounts of water (water loading) might slow down polycystic kidney growth or kidney function decline. Water loading can cause the suppression of a pathway that causes fluid buildup and cyst growth. High water intake has been safely used in the clinical setting, such as in the case of kidney stone therapy. New York State tap water is widely available and safe, making it highly cost-effective as well.
