Active clinical trials for "Diabetic Nephropathies"

The MEDiaN study aims to examine the state of fuel metabolism in participants with diabetic nephropathy (DN) before and after the use of the sodium-glucose transport protein 2 inhibitor (SGLT-2i) empagliflozin. The goals of the MEDiaN study are to better understand the contribution of fuel metabolism to the development of DN, and to determine if changes to fuel metabolism can have a positive impact on this disease. The MEDiaN study is a single-center single-arm open-label intervention study to examine the effects of empagliflozin 10mg daily taken for 30 days on fuel oxidation patterns in participants with type 2 diabetes and DN.

PF-03882845 is a compound proposed for treatment of type 2 diabetic nephropathy. The primary purpose of this trial is to evaluate the safety and tolerability, pharmacokinetics and pharmacodynamics of multiple doses of PF-03882845 in this population.

The purpose of this study is to characterize the effects of 85 days treatment with MLN1202 on urinary albumin-to-creatinine ratio (UACR) in participants with type 2 diabetes, advanced kidney disease/diabetic nephropathy (DN) and macro-albuminuria (UACR>300 mg/g) based on average of 3 consecutive first morning voids sample collection.

To explore the efficacy of Ivabradine for the treatment of microalbuminuria in patients with type 2 diabetes and coronary heart disease.

This project is an intervention study where type 2 diabetic patients will rotate through 4 different albuminuria lowering drugs with the aim to 1) quantify the individual relationship between drug exposure and albumin lowering response of different albuminuria lowering drugs in type 1 and type 2 diabetics; and 2) to investigate the effect of the same drug intervention on the glycocalyx layer in blood vessels. The overall purpose of this study is to allow for future personalized treatment of diabetics with regards to treating kidney disease more effectively than current standardized strategies.

The primary aim is to evaluate the anti proteinuric effect of increasing doses of the ACE inhibitor, lisinopril: 20, 40 and 60 mg daily in type 1 diabetic patients with hypertension and diabetic nephropathy. The secondary aim is to evaluate the effect on blood pressure (24 hour ambulatory blood pressure) and kidney function (glomerular filtration rate (GFR)). The tertiary aim is to evaluate differences in response to treatment according to ACE/insertion/deletion (ID)-genotypes and other genetic variants in the genes of the renin angiotensin system.

Background: Diabetes is common among American Indian people and diabetic kidney disease is a common complication. Kidney disease caused by diabetes can lead to the need for kidney replacement, by dialysis or kidney transplant, and is also associated with higher risk of early death. A new diabetes medicine called empagliflozin may slow kidney disease from type 2 diabetes. Researchers want to learn if it protects the kidneys when used in very early stages of diabetic kidney disease. Objectives: To see if empaglifozin delays kidney disease development. Eligibility: Adults 18-64 years old who are at least half American Indian and have had type 2 diabetes at least 5 years Design: Participants will be screened with health questions, blood pressure, and blood and urine tests. Participants will have: Medical history Physical exam Blood, urine, and stool samples taken Scan of the kidneys and liver. Participants will lie on a table that slides into an MRI machine. They will hold their breath for up to 20 seconds and the MRI machine will take images of their kidneys and liver. They will then repeat this with a small device that vibrates on their side. Kidney tests. A needle will be placed in a vein in each arm for 4 hours. Blood pressure will be taken. Participants will drink several quarts of water and urinate every 20 minutes. Urine and blood samples will be collected. Two liquids will be injected into their veins to measure kidney function. Photos of the back of the eyes Kidney biopsy. Participants will have a scan and get drugs to make them sleepy. Up to four very small pieces of kidney will be removed by needle. After the biopsy participants will be monitored for at least 4 hours. Nerve tests Participants will take the study drug or placebo pill once a day. Participants will attend for tests every twelve weeks and have more extensive kidney function tests once a year. After 3 years, participants will have another kidney biopsy and then stop taking the study drug. They will have a final kidney function test 2 months later.

Background: SGLT2 inhibitors are the first antiglycaemic drugs with a direct renal action. A part from reducing blood glucose, systemic blood pressure and albuminuria are decreased, while natriuresis is increased. Previous research into urinary peptide patterns (proteomics) has revealed that patients in risk of progressive renal disease display a "risk peptide pattern" in their urine, ahead of decline in renal function. Furthermore a urinary proteome pattern is related to CVD risk. The long-term impact of dapagliflozin (dapa) treatment on renal parameters is unknown, but long term randomized trials are ongoing. By investigating the impact of dapa treatment on this peptide pattern, it will be determined whether this intervention can improve the urinary proteomic peptide pattern. In addition new knowledge regarding renal processes that the treatment influences is sought. The impact of treatment of urinary and tubular markers of oxidative stress and function (metabolomics) will be assessed. These markers are thought to represent one of several deleterious pathways involved in the pathology of diabetic renal disease, and here the impact dapa treatment will be investigated. Improvement of these markers of oxidative stress may indicate long-term benefit. Objective: The primary objective is to assess the impact of three months of treatment with dapa 10 mg once daily or placebo on renal proteomics pattern and other risk markers of diabetic comorbidity. Design: Double blinded, randomized, placebo-controlled crossover, single center study. Treatment period: 2 x 12 weeks. Patient population: 40 patients with type 2 diabetes recruited from Steno Diabetes Center in accordance with the study in- and exclusion criteria. Intervention: Dapa 10 mg daily vs. placebo. Endpoints: Primary outcome: To evaluate the effect of dapa treatment on urinary proteomic patterns in patients with type 2 diabetes, microalbuminuria and eGFR equal to or above 45 ml/min/1.73m2. Secondary endpoints are the effect of the intervention on other markers for tubular function, inflammation, endothelial dysfunction, microcirculation, kidney function, albuminuria, vasoactive hormones in plasma, and effect on global longitudinal strain as measured by echocardiography. Timeframe: Randomisation planned from June 2015, inclusion over the following 9 months. Last patient is expected to be completed October 2016. Data analysis completed December 2016, presentation autumn 2017 and publication early 2018.

This is a prospective, multicenter, randomized, double blind, placebo-controlled and a prospective observational study. This study will be conducted at 15 study centers in various European countries. 1777 participant between 18 to 75 years old with Type 2 diabetes mellitus and normoalbuminuria participate in the study. The study period is 2 - 4.5 years (excluding the 6 week screening period). Depending on the risk score of the urinary protein pattern, participants have been stratified into an observational group or an interventional group. Participants with the low risk pattern (observational group) attend visits annually after screening and baseline. Participants with the high risk pattern (interventional group) attend study visits every 13 weeks after screening and baseline. The interventional group has been allocated into one treatment group either receiving spironolactone or placebo. A placebo is a medicine without a pharmaceutical substance. The allocation to one of the two treatment groups has been done by a random distribution procedure established before the study start. The results of the urine sample from the Screening visit has been analysed and the urine proteomic pattern is determined to be either low- or high risk pattern and will determine the further study program. Participants with a low-risk pattern (observational group): During the study period, participants attend an annual project visit, were regular diabetes care is performed and three urine samples are analysed for albuminuria. Participants with a high-risk pattern (intervention group): Participants with a high-risk pattern have been randomized to either spironolactone treatment or placebo. The treatment is one tablet for oral use to be taken once a day for the entire study period. Four times each year (every 13th week) a study visit is conducted including examination of three urine samples for albuminuria. This study aims to: Confirm in a prospective multicenter study of normoalbuminuric type 2 DM patients that the urinary proteome test identifies patients with a high risk for development of microalbuminuria. Demonstrate the clinical utility of the test by showing that aldosterone blockade in high-risk patients can reduce progression to microalbuminuria in comparison to placebo, on the top of standard treatment in a randomized double-blind, placebo-controlled multicenter study.

The primary objective of this study is to evaluate the efficacy of two different doses of Pyridorin (150 mg and 300 mg)compared to placebo in retarding the progression of diabetic nephropathy. This will be assessed by measuring the change in serum creatinine and other biomarkers of kidney disease during the course of the 1-year study.
