Active clinical trials for "Albuminuria"

The purpose of the study is to compare the change from baseline in blood pressures (DBP/SBP) to 16-week regimen between Amtrel® and Co-Diovan®. The secondary objectives were listed as the following. To compare the response rate (defined as SBP < 130 mmHg and DBP < 80 mmHg) at the end of study To evaluate the change from baseline in albumin-to-creatinine ratio with antihypertensive medications in whole group (combined treatment groups) and each treatment group (Amtrel®, Co-Diovan®) at Week 16 The change from baseline in glycosylated hemoglobin (HbA1c) at Week 16 The change from baseline in fasting plasma glucose (FPG) at Week 16 The change from baseline in fasting lipid profiles (triglyceride, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol) at Week 16 The change from baseline in arteriosclerosis marker (brachial-ankle pulse-wave velocity (ba-PWV) and ankle-brachial pressure index (ABI), using Colin-VP1000) at Week 16 The change from baseline on the body mass index (BMI) and waist-hip ratio (WHR) at each specified study time point To ascertain the safety and tolerability of Amtrel® versus Co-Diovan® including AE/SAE, and laboratory examinations

The purpose of this study is assess if treatment with valsartan and a diuretic, hydrochlorothiazide, has beneficial effects in people with high blood pressure, diabetes, and albuminuria (protein in the urine) compared with amlodipine. In particular, the study will assess whether the treatment will decrease the stiffness of the blood vessels.

The study objective was to evaluate the safety of paricalcitol capsules and the efficacy of paricalcitol capsules for albuminuria reduction in patients with Chronic Kidney Disease (CKD) who have Type 2 diabetic nephropathy and are receiving optimal angiotensin converting enzyme (ACE) inhibitor and/or angiotensin II receptor blocker (ARB) therapy.

Vascular endothelial dysfunction increases cardiovascular (CV) risk and contributes to the progression of chronic kidney disease (CKD). Mineralocorticoid receptor (MR) antagonists have been shown to improve endothelial function, as well as decrease CV mortality and proteinuria. The specific biochemical pathways that produce these pharmacological effects for MR antagonists, however, are poorly understood. This study investigates the effect of MR antagonism on endothelial function in patients with moderate (stage III) CKD using a randomized, controlled trial. Three specific aims are proposed: Aim 1: To determine if spironolactone improves endothelial function as compared to amiloride in patients with stage III CKD; Aim 2: To determine if oxidative stress is associated with changes in endothelial function by spironolactone compared to amiloride in patients with stage III CKD; and Aim 3: To determine if endothelial dysfunction contributes to albuminuria in patients with stage III CKD. The clinical relevance is to improve understanding of the mechanisms of kidney function decline in CKD in order to develop interventions to delay or prevent dialysis, which would translate into alleviating patient suffering, caregiver burden, and health care costs.

Patients with Focal Segmental Glomerulosclerosis (FSGS) constitute an increasing proportion of the total glomerulonephritis (GN) patient cohort in North America while FSGS is a risk factor for end stage renal failure. Current non-immunological FSGS therapies include the use of angiotensin converting enzyme inhibitors (ACEi) or angiotensin II receptor blockers (ARB), to reduce intraglomerular hypertension. Unfortunately, these agents lead to incomplete renal protection. The aim of the current study is to determine whether the addition of novel sodium glucose cotransport-2 inhibitors (SGLT2i) to standard of care leads to reduced intraglomerular pressure and suppression of proteinuria. We hypothesize that combination therapy of SGLT2i drugs and conventional RAASi results in additive renal protective effects in FSGS patients. A further goal is to examine mechanisms of SGLT2 inhibition by measuring renal hemodynamic function and sodium handling. Kidney function will be assessed in FSGS patients before and after an 8 week treatment with SGLT2i dapagliflozin.

The purpose of this study is to evaluate the effect of treatment with CCX140-B on urinary albumin excretion in subjects with type 2 diabetes mellitus and albuminuria, as well as to study the safety and efficacy of the medication in this patient population.

The purpose of this study is to determine the safety and effect of green tea (epigallocatechin gallate) in albuminuria in diabetic patients and nephropathy.

The study objective is to investigate the effects of three low doses of atrasentan on urinary albumin/creatinine ratio (UACR) levels in subjects with Type 2 diabetic nephropathy. Patients with Type 2 diabetes with nephropathy must be receiving a renin-angiotensin system inhibitor, such as an Angiotensin converting enzyme inhibitor (ACEi) or an Angiotensin II Receptor Blocker (ARB) for participation in this study. ACEi and ARB treatment are the standard of care for the management of proteinuria in Chronic Kidney Disease (CKD) patients.

Prospective, Randomized, Double-Blind, Placebo-Controlled Multicenter Study. The objective of the study is to evaluate the efficacy and safety of once daily administration of atrasentan tablets (low dose and high dose) compared to placebo in reducing residual albuminuria in Type 2 diabetic patients with nephropathy who are treated with the maximum tolerated labeled dose of a Renin Angiotensin System (RAS) inhibitor. If the patient is already receiving a maximum tolerated labeled daily dose of RAS inhibitor and a diuretic, he/she will complete 4 weeks of the Run-in Period on a dose that has not been adjusted. If the patient is currently not receiving a maximum labeled daily dose of a RAS inhibitor then the dose will be titrated up to the maximum tolerated labeled dose over the course of 4 to 8 weeks during the Run-in Period. It is expected that subjects not receiving a diuretic will have a diuretic added or titrated during this period to maximize RAS inhibition. Following titration to the maximum tolerated labeled dose, the patient will complete an additional 4 weeks of Run-In Period on an unchanged doses of RAS inhibitor and diuretics, unless medically contraindicated. The randomization will be stratified based on country where subjects are enrolled into the study, and the Week -1 Urinary Albumin to Creatinine Ratio (UACR) levels (< or = 1000 mg/g [113 mg/mmol], or > 1000 mg/g [113 mg/mmol]). Within each stratum, subjects will be randomly assigned in a 1:2:2 ratio to one of the following blinded treatment groups: Group A - Placebo once daily (QD) Group B - low dose atrasentan QD Group C - high dose atrasentan QD After the 12 weeks of study drug treatment, subjects will be followed up to 30 days.

Patients with chronic kidney disease (CKD) and albuminuria are at increased risk of developing cardiovascular disease (CVD) which is often associated with hypertension, left ventricular hypertrophy, endothelial dysfunction and increased generation of reactive oxygen species (ROS). These patients also manifest a decrease in nitric oxide (NO) availability which is thought to play an important role in their progressive vascular disease. Tetrahydrobiopterin (BH4), an essential cofactor for endothelial nitric oxide synthase(eNOS), an important regulator of NO and that is a key mediator of endothelial dysfunction. Changes in NO availability are believed to contribute to endothelial dysfunction seen in CKD and common CVD states. 6R-tetrahydrobiopterin (6R-BH4 or sapropterin dihydrochloride) is an investigational oral drug that is being evaluated to determine whether it will restore NO availability, leading to beneficial effects on vascular function and ultimately positive clinical outcomes in patients with CKD. The primary endpoint in this study is the level of albuminuria, an easily measured marker that has served as a predictor of kidney disease progression. If 6R-BH4 reduces albuminuria in patients with kidney disease, it may have implications to slow the disease progression as well as decreased risk of CVD.
