Active clinical trials for "Diabetic Nephropathies"

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.

This study will build a population management system Simultaneous risk factor control using Telehealth to slOw Progression of Diabetic Kidney Disease STOP-DKD Application STOP-DKD APP and conduct a 6-month controlled trial to compare reduction of blood pressure. In addition, the study will evaluate the feasibility of future large-scale intervention to slow diabetic kidney disease (DKD) DKD progression. Aim 1: Identify patients with moderate DKD and uncontrolled hypertension (HTN) using existing electronic health record data in an integrated data warehouse (Southeastern Diabetes Initiative- SEDI) to screen all patients within SEDI. Aim 2: Implement an intervention designed to slow progression of DKD and treat associated conditions in a high-risk population with moderate DKD and uncontrolled HTN using the STOP-DKD APP Primary Outcome: Test the hypothesis that patients who receive the intervention will have greater improvements in blood pressure as compared to a control group after 6 months Secondary Outcomes: Exploratory analyses to determine whether patients who receive the intervention will have less progression (defined as a smaller decrease in kidney function), and improved behaviors that affect HTN control and cardiovascular risk (medication adherence, diet, physical activity, and weight control) as compared to a control group after 6 months Aim 3: Evaluate the STOP-DKD APP Study to guide large-scale implementation & dissemination Impact Evaluation: Assess the potential population impact of our intervention using the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework Economic Evaluation: Conduct an economic evaluation using the Archimedes Model by estimating projected costs and quality-adjusted life-years

Background: Diabetic kidney disease (DKD) is chronic and often progresses to kidney failure,heart disease and premature death. Unfortunately, the best medical therapies available for DKD today are ultimately unable to prevent its progression, especially in obese patients.Surgical rerouting of food within the gut with a gastric bypass operation (RYGB), improves diabetes and some of its complications. The investigators propose to investigate whether RYGB in combination with best medical therapy in patients with DKD and obesity prevent further deterioration of kidney function over a 3 years follow up period. Study design: This is an international collaboration with leading centres in Sweden and Switzerland in which100 obese type 2 diabetic patients with established DKD will volunteer to be randomly assigned to receive best medical therapy with RYGB or best medical therapy without surgery. Participants will be 18-65 years with type 2 diabetes and impaired kidney function. Yearly measurements of kidney function will then be done over a period of 3 years as a primary outcome to determine whether differences in DKD can be detectable. The study will also examine and compare a) safety of the interventions, b) the health economic impact on direct healthcare costs and Quality of Life in patients as well as c) the value of a new marker of DKD in determining which patients are most likely to benefit from surgery. Overall the study will strengthen the evidence base guiding clinical decisions about the usefulness of RYGB as an add on therapy to best medical therapy in stopping progressive DKD in patients with obesity and diabetes.

Despite improvements during the past 20 years in blood glucose and blood pressure control, diabetic kidney disease remains one of the most important causes of health problems in patients with diabetes. Novel treatments to complement blood glucose and blood pressure control are urgently needed. The goal of this study is to see whether a medication called allopurinol may help prevent loss of kidney function among people with type 1 diabetes. Allopurinol has been used for many years to decrease high blood uric acid and treat gout - a disease characterized by arthritis, especially of the foot joints. There is evidence suggesting that allopurinol might also be useful in people with diabetes who have normal or moderately impaired kidney function to decrease the risk of developing advanced kidney disease in the future. To prove this beneficial effect of allopurinol, we will be conducting an international clinical trial at eight diabetes centers, enrolling approximately 480 patients with type 1 diabetes who are at increased risk of developing kidney disease. Participants will be randomly assigned to take allopurinol or placebo (inactive pill) for three years, during which they will be followed through periodical visits. To prevent any possible bias, neither the participants nor the clinical staff knows who is taking allopurinol and who is taking the placebo. Kidney function will be measured at the beginning and at the end of the treatment period to see whether patients taking allopurinol experience a slower loss of kidney function over time as compared to those taking the inactive pill. If this trial is successful, the reduction in health problems resulting from the prevention or delay of kidney function loss due to the use of allopurinol would have a major impact on the lives of type 1 diabetic patients as well as on society at large, significantly reducing the human and financial costs associated with diabetic kidney disease. Because of the emphasis on early intervention, the proposed trial, if successful, will establish a new paradigm in treatments to slow or prevent progression towards end stage kidney disease in type 1 diabetes far beyond anything achieved to date.

The purpose of the study is to assess the accuracy of the Dexcom G6 CGM system and the Abbott FreeStyle Libre flash system compared to the reference standard YSI (Yellow Spring Instruments) glucose in people with diabetes undergoing haemodialysis. The Dexcom G6 is a continuous glucose monitoring system that gives blood glucose values in real-time and includes alarms if the glucose is very low or high. The Abbott FreeStyle ibre flash system is an intermittent glucose monitor that shows the blood glucose values when it is waved near the sensor and does not include alarms. The YSI glucose analysis will take place as a normal part of haemodialysis, by testing blood glucose levels during the haemodialysis session. The study will last 28 days per participant

Background: Worldwide, diabetic nephropathy or Diabetic Kidney Disease (DKD), is the most common cause of chronic and end-stage kidney disease. With the increasing rates of obesity and type 2 diabetes (T2DM), many more patients with DKD may be expected in the coming years. Large-sized prospective randomized clinical trials suggest that intensified glucose and blood pressure control, may halt the progression of DKD, both in type 1 diabetes and T2DM. However, despite the wide use of angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, a considerable amount of patients develop DKD during the course of diabetes, indicating an unmet need for renoprotective therapies. Sodium-glucose linked transporters (SGLT-2) inhibitors are novel glucose-lowering drugs for the treatment of T2DM. These agents seem to exert pleiotropic actions 'beyond glucose control', including reduction of blood pressure and body weight. In addition, SGLT-2 inhibitors decrease proximal sodium reabsorption and decrease glomerular pressure and albuminuria in rodents and type 1 diabetes patients. In rodents, SGLT-2 inhibitors also improved histopathological abnormalities associated with DKD. To date, the potential renoprotective effects and mechanisms of these agents have not been sufficiently detailed in human type 2 diabetes. The current study aims to explore the clinical effects and mechanistics of SGLT-2 inhibitors on renal physiology and biomarkers in metformin-treated T2DM patients with normal kidney function. Study Design: Randomized, double-blind, comparator-controlled, intervention trial Study Endpoints: Renal hemodynamics, i.e. measured glomerular filtration rate (GFR, ml/min) and effective renal plasma flow (ERPF, ml/min); 24-hour urinary solute excretion; markers of renal damage ; blood pressure; body anthropometrics; systemic hemodynamic variables (including stroke volume, cardiac output and total peripheral resistance); arterial stiffness will be assessed by applanation tonometry, (SphygmoCor®); insulin sensitivity and beta-cell function. Expected results: Treatment with the SGLT-2 inhibitor dapagliflozin, as compared to the sulfonylurea (SU) derivative gliclazide, may confer renoprotection by improving renal hemodynamics, and decreasing blood pressure and body weight in type 2 diabetes.

Current study will render insight in to the role of renal hypoxia in the diabetic kidney and is able to associate its finding with measurements of renal perfusion and glomerular filtration rate. Moreover, this research will focus on the effects of sodium-glucose cotransporter 2 inhibition on renal tissue oxygenation and oxygen consumption as well as a change in intrarenal hemodynamics and perfusion, and a shift of fuel metabolites. Elucidation the mechanisms underlying the effects of SGLT2 inhibition will advance our knowledge and contribute to their optimal clinical utilization in the treatment of chronic kidney disease in diabetes and possibly beyond.

The primary objective of this clinical study is to evaluate the effectiveness and safety of PH3 for patients with diabetic nephropathy. The secondary objectives are to identify the optimal dosage for subsequent studies and to provide basis for the next confirmatory study in study design, endpoints, and study methodologies.

Over 1.25 million Americans have type 1 diabetes (T1D), increasing risk for early death from cardiorenal disease. The strongest risk factor for cardiovascular disease (CVD) and mortality in T1D is diabetic kidney disease (DKD). Current treatments, such as control of hyperglycemia and hypertension, are beneficial, but only partially protect against DKD. Hyperfiltration is common in youth with T1D, and predicts progressive DKD. Hyperfiltration is also associated with early changes in intrarenal hemodynamic function, including increased renal plasma flow (RPF) and glomerular pressure. Intrarenal hemodynamic function is strongly influenced by the renin-angiotensin-aldosterone system (RAAS), which is also considered a key player in the pathogenesis of DKD. Preliminary data demonstrate differences in intrarenal hemodynamic function and RAAS activation in early and advanced DKD in T1D. However, the pathophysiology contributing to the differences observed in RAAS activation and intrarenal hemodynamic function in T1D are poorly defined Animal research demonstrates that arginine vasopressin (AVP) acts directly to modify intrarenal hemodynamic function, but also indirectly by activating RAAS. Preliminary data suggest that elevated copeptin, a marker of AVP, which predicts DKD in T1D adults, independently of other risk factors. However, no human studies to date have examined how copeptin relates to intrarenal hemodynamic function in early DKD in T1D. A better understanding of this relationship is critical to inform development of new therapies targeting the AVP system in T1D. Accordingly, in this study, the investigators propose to define the relationship between copeptin and intrarenal hemodynamics in early stages of DKD, by studying copeptin levels, renal plasma flow, and glomerular filtration in youth (n=50) aged 12-21 y with T1D duration < 10 y.

In people with type 2 diabetes (T2D), the body makes insulin, but cannot use it well. This results in high blood sugar levels causing damage to the blood vessels inside the kidneys. High blood pressure is a common condition that can cause damage to the blood vessels and heart if it is untreated. High blood pressure is also known as hypertension. Patients with type 2 diabetes (T2D) or high blood pressure are at a higher risk of having chronic kidney disease (CKD). In people with CKD, the kidneys become damaged and do not work as they should. Over time, the function of the kidney declines more, and this can lead to the requirement for dialysis or kidney transplantation. Most people with CKD are also at risk of heart conditions, such as heart attack or stroke. In this trial, the researchers want to learn if BAY2327949 reduces the amount of protein in the participants' urine. Protein in the urine is one of the signs of CKD. The researchers will compare the effects of BAY2327949 to a placebo. A placebo looks like the study drug but does not have any medicine in it. BAY2327949 is assumed to increase the blood flow through the kidneys, which may slow down the worsening of the disease. The researchers will use a placebo to learn if the changes seen in the participants are due to BAY2327949 or if the results could be due to chance. This trial will include about 120 men and women over the age of 45 who have CKD. The participants will have T2D or high blood pressure, and a further disease of the heart or blood vessels. During the trial, the participants will take either BAY2327949 or a placebo once a day for 28 days. The participants will visit their trial site about 9 times during the trial, and need to provide urine samples to check the participants' CKD symptoms. At the visits, the doctors will ask them if they have any health problems. They will also take blood samples to perform laboratory assessments.
