Active clinical trials for "Polycystic Kidney Diseases"

To assess the efficacy of lanreotide in controling total liver volume in patients with polycystic livers this study will be performed. A minimum of 38 patients will be recruited and randomized (1:1) to receive either verum or placebo. Lanreotide is already used in other disease states and found to be safe and non-toxic.

The purpose of this study is to determine whether the medication pravastatin will ameliorate renal and cardiovascular disease over a 3-year period in children and young adults with autosomal dominant polycystic kidney disease (ADPKD).

Autosomal-Dominant Polycystic Kidney Disease (ADPKD) is the most common hereditary renal disease, characterized by the progressive development of fluid-filled cysts in the kidney leading to progressive loss of renal function and eventually to renal failure. It is responsible for 8% to 10% of the cases of end stage renal disease (ESRD) in Western countries. ADPKD progression is largely dependent on the development and growth of the cysts and secondary disruption of the normal tissue. Renoprotective interventions in ADPKD - in addition to achieve maximal reduction of arterial blood pressure and proteinuria and to limit the effects of additional potential promoters of disease progression such as dyslipidemia, chronic hyperglycemia or smoking - should also be specifically aimed to correct the dysregulation of epithelial cell growth, secretion, and matrix interactions characteristic of the disease. Genetically in the ADPKD three different genes are implicated (PKD1 85% of the cases, PKD2 15% and probably PDK3 not yet identified). PKD1 gene encodes a protein named polycystin-1 (PC1). Defect in PC1 lead to aberrant activation of the enzyme mTOR in the epithelial cells of the renal tubules which eventually leads to abnormal proliferation of these cells and cysts generation. Sirolimus (Rapamycin) is an immunosuppressant mostly used for the management of kidney transplant recipients. This drug by very specifically and effectively inhibiting mTOR, exerts antiproliferative and growth inhibiting effects and could be extremely important for the inhibition of cyst progression in ADPKD. Animal models of ADPKD have shown that short-term treatment with sirolimus resulted in dramatic reduction of kidney size, prevented the loss of kidney function, and lowered cyst volume density. Similarly, retrospective observations from kidney transplant recipients have documented that sirolimus treatment reduced kidney volumes by 25%, whereas there was no effect in patients not given the drug. Overall, these findings provide the basis for designing a prospective study in ADPKD patients aimed to document the efficacy of sirolimus treatment in preventing further increase or even reducing the total kidney volume and the renal volume taken up by small cysts, eventually halting kidney disease progression. It is a 6 month treatment with sirolimus compared to conventional therapy in adult patients with ADPKD and normal renal function or mild to moderate renal insufficiency.

The general aim of the trial is to assess the efficacy of one year treatment with long-acting somatostatin analogue (Octreotide LAR) compared with placebo in slowing kidney and liver growth rate in patients with ADPKD and moderate/severe renal insufficiency and to assess whether and to which extent this translates into slower renal function decline over 3-year follow-up.

LIPS study (Lanreotide In Polycystic kidney disease Study) is a prospective randomized double blind placebo controlled study. The main objective is to prove that lanreotide, a somatostatin analog, is able to reduce the glomerular filtration rate decline over 3 years by at least 30%. Cardiovascular outcomes, blood pressure, quality of life and safety are among the secondary outcomes. The study, which will include 180 ADPKD patients, is scheduled to start in early 2014. An equal number of patients with chronic kidney disease stage 2 (90 patients with GFR 89 to 60 ml/mn/1.73 m2) and chronic kidney disease stage 3 (90 patients with GFR 59 to 30 ml/mn/1.73 m2) will be included. The primary endpoint (GFR decline) will be assessed by repeated measures, in the overall population as well as in the two GFR stratus.

Autosomal dominant polycystic kidney disease (ADPKD) is associated with the development of a variety of extrarenal manifestations of which polycystic liver disease is most common. The investigators aimed to assess the changes over time of liver volume in ADPKD patients and whether it is affected by the treatment with the somatostatin analogue, octreotide. 35 ADPKD patients (14 males) aged 34±8 years were randomly assigned to 36 month treatment with placebo (n=18) or octreotide (n=17). Clinical and liver parameters at magnetic resonance (RM) were evaluated at baseline, study end and after 24 months of drug withdrawal.

This study was designed to provide confirmation of safety of mesenchymal stem cells (MSCs) therapy in chronic renal failure due to autosomal dominant polycystic kidney disease (ADPKD).

This study is being done to determine if treatment with metformin, a drug widely used for the treatment of diabetes type 2, is safe and well tolerated by individuals with Autosomal Dominant Polycystic Kidney Disease (ADPKD) who are not diabetic and who have slightly decreased kidney function. The study will also evaluate the effects of metformin on kidney growth and kidney function.

The proposed research will determine the effectiveness of curcumin for improving the health and function of arteries in children and young adults with autosomal dominant polycystic kidney disease (ADPKD). The study also will provide insight into how curcumin improves artery health by determining the physiological mechanisms (biological reasons) involved and offer exploratory evidence if curcumin can slow kidney growth. This will be done by comparing these measurements in children and young adults who are randomized to receive either curcumin or placebo for 1 year.

Autosomal dominant polycystic kidney disease (ADPKD) is the most common single gene disorder that is potentially fatal. ADPKD is caused by mutations in either of two genes (PKD1, PKD2). Cysts begin to develop primarily in renal collecting tubules in utero and continue to form and expand throughout the patient's life. One of the goals of the study is to formulate a water prescription for use in clinical trials to determine the effect of sustained water diuresis on the progression of ADPKD.
