Active clinical trials for "Renal Insufficiency, Chronic"

An open-label, phase IB, multi-center study evaluating DM199 in subjects with Type 1 Diabetes or Type 2 Diabetes and Stage 3 or 4 Chronic Kidney Disease. The primary objectives of this study are to evaluate safety, tolerability, and PK profile of DM199 in these subjects.

This is a Phase 2, randomized, double-blind, placebo-controlled, dose-finding study to assess the efficacy, safety, tolerability, pharmacokinetic (PK), and pharmacodynamic (PD) of orally administered vadadustat in Japanese participants with anemia secondary to Dialysis-dependent Chronic Kidney Disease (DD-CKD).

To evaluate in patients with chronic kidney disease the impact of two dosages of per os vitamin D3 supplementation (cholecalciferol) on large arterial stiffness (evaluated non invasively by pulse wave velocity and high-resolution echotracking system). We will also study arterial calcification (lateral abdominal radiography and echocardiogram), arterial remodeling (high-resolution echotracking system), endothelial function (evaluated by a non-invasive finger biosensor device), and bone remodeling (evaluated by serum biomarkers and bone mineral density).

The most common co-morbidity accompanying Chronic Kidney Disease (CKD) is hypertension, which appears in approximately 80% of all patients with renal dysfunction, whereas its prevalence in general population is remarkably lower appearing in approximately 30% of adults.Defining hypertension in ESRD patients under maintenance dialysis is a challenging procedure. Ambulatory blood pressure monitoring (ABPM) is considered the "gold standard" for the diagnosis of hypertension in hemodialysis patients over the last years. The major pathophysiologic mechanism underlying hypertension development in patients with ESRD under hemodialysis is water and sodium overload. Identifying an accurate and objective method of dry weight evaluation has been a matter of intensive nephrology research for more than two decades. Assessment of the water balance in hemodialysis patients on the basis of common clinical criteria (e.g. leg or face swelling or signs of lung congestion) is a subjective method with limited reliability, despite its widespread use. Recently, a novel technique has been developed to quantify water excess by conducting an ultrasound lung scan. Pilot studies have shown significant changes in lung water in hemodialysis patients according to body weight changes during interdialytic days and dialysis sessions. Moreover, results from previous studies indicate significant benefits from dry weight probing with regards to blood pressure (BP). The clinical application of a lung-ultrasound-based volume control strategy in hemodialysis patients is currently being tested by the randomized study entitled "Lung water by ultrasound guided treatment to prevent death and cardiovascular complications in high risk end stage renal disease patients with cardiomyopathy (The LUST Study)". This clinical trial aims at evaluating whether the use of the number of US-B lines could be used as a biomarker to guide a per-protocol intensification of ultrafiltration (UF) in order to reduce volume overload, improve cardiac function and prolong survival. Cardiovascular disease in patients with CKD is attributed to a spectrum of structural and functional alterations of the large and the small branches of the arterial tree. The most important process in patients with advanced CKD is that of arteriosclerosis, which is developed in parallel to atherosclerosis and is typically associated with impaired cushioning function of the aorta and the large conduit arteries. Accelerated arterial stiffening is involved in the development of isolated systolic hypertension, left ventricular hypertrophy (LVH) and congestive heart failure (CHF), which predispose to arrhythmias and sudden cardiac death. In the context of the phenomenon of "aortic-to-brachial BP amplification", systolic BP (SBP) and pulse pressure (PP) conventionally measured at the level of brachial artery are higher than the relevant pressures in the ascending aorta. Due to extreme elevation of arterial stiffness, BP amplification is disturbed in patients with ESRD. Prospective cohort studies have demonstrated that elevated central PP, wave reflections and arterial stiffness, as well as, reduced PP amplification represent strong and independent predictors of all-cause and cardiovascular mortality in hemodialysis patients. On this basis, estimation of central BP indices appears as an important tool towards optimisation of cardiovascular risk stratification in ESRD as well as in other diseased populations. Until recently, available devices for ABPM evaluated BP levels only at the level of brachial artery. The newly developed Mobil-O-Graph NG (IEM, Stolberg, Germany) provides the ability to monitor central aortic pressure and indices of vascular resistance, such as wave reflections (augmentation index, AIx) and arterial stiffness (pulse wave velocity, PWV).This device has recently been validated in hemodialysis patients and showed comparable performance with the widely used tonometric SphygmoCor device (ArtCor, Sydney, Australia). Accumulated evidence over central BP and PWV in hemodialysis patients derives mostly from studies that included only static pre-dialysis and post-dialysis measurements. However, variations of BP levels during intra- and interdialytic intervals combined with the superiority of aortic BP measurements, as analysed above, indicate that ambulatory monitoring of central BP is the best available method. This study aims for the first time to evaluate the outcome of a treatment strategy for dry weight probing, based on volume overload quantification with lung ultrasound, on 48-hour peripheral systolic BP, aortic BP and arterial stiffness in hemodialysis hypertensive patients. This is a Lust Sub-Study. Additional information can be found at: NCT02310061.

The objectives of this study are to assess the long-term efficacy and safety of different dose regimens of KRX-0502 in the treatment of iron deficiency anemia (IDA) in adult subjects with non-dialysis dependent chronic kidney disease (CKD).

The study will evaluate the within-subject variability of 20mg ER torsemide as compared to 20mg IR torsemide (Demadex) in fully replicate double-crossover trial in healthy volunteers, who are consuming a high-salt diet (300 mmol/day). The study will also evaluate the effects of ER torsemide and IR torsemide on 24h sodium excretion and total urinary excretion.

This study aims to verify the effects of low level laser therapy (LLLT) on functional capacity, DNA damage, lower limbs muscle strength, quadriceps muscle architecture, muscle pain and perception of lower limb fatigue, inflammatory profile, oxidative stress and quality of life of patients with chronic kidney failure on hemodialysis. Patients will be randomized into two groups: the control group and the LLLT group. The control group will only be evaluated and reassessed. The LLLT group in addition to the evaluations will receive LLLT three times a week for eight weeks during HD. The evaluations will be performed pre-intervention, after 4 and 8 weeks of therapy. However, the muscle architecture evaluation will be performed only at pre intervention and after 8 weeks. The evaluations carried out are: six-minute walk test for functional capacity; alkaline comet assay for DNA damage; sit-and-lift test, and load cell dynamometry for evaluation of lower limbs muscle strength; quadriceps ultrasonography for muscle architecture and echogenicity; visual analogue scale for pain; subjective perception of effort by Borg scale for fatigue; measurement of interleukins 6 and 10, tumor necrosis factor, reative C protein and muscle damage markers (lactate, creatine kinase) for the inflammatory profile; protein carbonylation, superoxide dismutase, catalase, total sulfuric acid and dichlorofluorescein diacetate for oxidative stress and application of the Kidney Disease and Quality-of-Life-Short-Form and EQ-5D questionnaires for quality of life.

The primary objectives of this study are to evaluate the safety, tolerability, and efficacy of tenofovir alafenamide (TAF) versus tenofovir disoproxil fumarate (TDF)-containing regimens at Week 24 in participants with chronic hepatitis B virus (HBV) infection and Stage 2 or greater chronic kidney disease who have received a liver transplant.

A pilot, single-center, prospective, interventional study. The objective is to demonstrate that catheter-based renal denervation using carbon dioxide renal angiography in patients with moderate to severe chronic kidney disease can be performed for treatment of uncontrolled hypertension.

This study evaluates the effect of oral sodium bicarbonate treatment on the intrarenal renin-angiotensin-system in adult patients with a metabolic acidosis and chronic kidney disease. This treatment is compared to sodium chloride treatment, which serves as control for increased sodium-intake and no treatment, which serves as time-control.
