Active clinical trials for "Kidney Diseases"

This is a pilot, randomized, double-blinded, placebo-controlled, 12-month trial of 50 patients with CKD stage 3b-4 with metabolic acidosis to examine the effect of sodium bicarbonate therapy on cognitive and cerebrovascular function.

The primary aim is to determine the effect of participant and provider knowledge of a positive APOL1 status and accompanying guideline based clinical decision support (CDS) on blood pressure management on change in systolic blood pressure (SBP) from baseline to 3 months after randomization among the APOL1 positive participants. Secondary aims are to: Determine the effect of participant and provider knowledge of a positive APOL1 status on the probability of appropriate CKD diagnosis. Determine the effect of participant and provider knowledge of a positive APOL1 status on the probability of receiving a urine microalbumin/creatinine testing and ACE-I/ARB prescription based on results of the urine microalbumin level. Explore cost effectiveness, mediators, moderators, psychobehavioral impact of results disclosure on participants, and effects of participant and provider knowledge of APOL1 status on provider treatment recommendations. PGX Substudy In addition, GUARDD-US will include a substudy to determine the effect of knowledge of genetic test results that predict efficacy of various antihypertensive medications on change in SBP from baseline to 3 months in APOL1 negative individuals. Approximately 6,650 participants of African ancestry age 18-70 with hypertension that either: 1) do not have diabetes and do not have CKD, or 2) have CKD. Participants with diabetes may be included as long as they also have CKD. Population for Main Study: Participants from Randomized Population (above) who test positive for APOL1 Population for PGx Substudy: Participants from Randomized Population (above) randomized to Intervention and who test negative for APOL1 Main Study Analyses: To determine the effect of participant and provider knowledge of a positive APOL1 status on SBP, we will compare the change in SBP from baseline to 3 months of the Intervention - APOL1 positive group to the change in SBP from baseline to 3 months of the Control - APOL1 positive group using a two sided t-test, as appropriate, with a two-sided type I error of 0.05. The effect of knowledge of a positive APOL1 status on all secondary endpoints will be compared between Intervention - APOL1 positives to Control - APOL1 positives with the proportion difference test. Additional analyses will include analysis of time trends in SBP, subset analyses, and exploratory analyses of cost effectiveness, mediators, moderators, psychobehavioral impact of results disclosure on participants, and effects of knowledge of APOL1 status on provider treatment recommendations. Substudy Analyses: All primary and secondary endpoint analyses conducted for the APOL1 main study will be repeated for the PGx substudy focusing on differences in outcomes between APOL1 negative individuals with immediate PGx ROR (PGx Intervention) and APOL1 negative individuals with delayed PGx ROR (PGx Control).

To determine the nephroprotective potential of treatment with sparsentan in patients newly-diagnosed with immunoglobulin A nephropathy (IgAN) (ie, incident patients) who have not received prior angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) therapy.

Evidence-Based Nutrition Practice Guidelines (EBNPGs) inform registered dietitian nutritionist (RDN) care for patients with chronic kidney disease grade 5 treated by dialysis (CKD G5D); however, there has been little evaluation of best practices for implementing EBNPGs. In this effectiveness-implementation hybrid study with a quasi-experimental design, United States RDNs in hemodialysis clinics will document initial and follow-up nutrition care for patients with CKD G5D using the Academy of Nutrition and Dietetics Health Informatics Infrastructure (ANDHII) before and after being randomly assigned to a training model: 1) EBNPG knowledge training, or 2) EBNPG knowledge training plus an implementation toolkit. Aims of the study include examining congruence of RDN documentation of nutrition care with the EBNPG; describing common RDN-reported EBNPG acceptability, adoption and adaptation issues; and determining the feasibility of estimating the impact of RDN care on nutrition-related patient outcomes. The AUGmeNt study can inform effective development and implementation of future EBNPGs.

Randomized, placebo-controlled, multi-center, double-blind, proof of concept phase IIa trial and dose evaluation trial of felzartamab in IgAN

Hyperuricemia is a common condition in patients with chronic kidney disease (CKD) in the glomerular filtration rate. Recently, it has been suggested that uric acid is related to a mineral and bone disease of CKD (CKD-MBD) since the high concentration of uric acid is associated with the harmful effect of vitamin D. The proof of concept of the association between acid uric acid and CKD-MBD is based on a prospective study (sample size 6) that observed, after 1 week of use of allopurinol, an increase in the concentration of 1,25(2D, a result independent of the concentration of calcium, phosphorus, 25(OH)D and PTH. An experimental study found that hyperuricemia could modify the expression of the 1α-hydroxylase enzyme, consequently reducing 1,25(OH). The current study aims to evaluate the action of allopurinol on CKD-MBD biomarkers (25(OH)-vitamin D, 1,25(OH)2D, FGF-23, PTH, calcium and phosphorus). We hypothesize that allopurinol can improve serum levels of 1,25(OH) 2D and PTH. This is a controlled, randomized, double-blind study, defined as a filtration rate < 60ml/1.73 m², according to the CKD-EPI equation. Inclusion criteria: patients with stages III, IV and V CKD who are not on dialysis with a serum level of 25(OH)-vitamin D >20 ng/ml. Exclusion criteria: Patients diagnosed with gout, undergoing treatment with allopurinol, patients already in use and drugs with sensitivity to the drug. Based on a previous study, we calculated a sample for 2 groups (placebo and drug) with pre and post-measurements (a total of 4). Considering a standard deviation of 4 and a difference of 7 in the treated group, 3 in the placebo group, and an alpha error of 5%, we calculated a sample of 25 patients in each arm.

The objective of this study is to investigate and compare the safety and efficacy of selective (PDE5) enzyme inhibitor; tadalafil and non selective (PDE) inhibitor; pentoxifylline in diabetic nephropathy to improve glucose metabolism, lipid profile and decrease albuminuria.

Investigator-initiated, interventional, prospective study to assess the clinical and operational effectiveness of daprodustat in adult patients receiving in center hemodialysis or peritoneal home dialysis who are transitioning from Mircera to daprodustat.

This is a single-center, prospective, single-arm clinical study to evaluate the feasibility, safety, and performance of VenoStent's SelfWrap® Bioabsorbable Perivascular Wrap on arteriovenous fistulas (AVFs). All participants are chronic kidney disease (CKD) patients already receiving hemodialysis treatments that are referred for creation of a new arteriovenous fistula (AVF).

The aim of this study is to evaluate the effect of administration of folic acid and /or pentoxifylline on patients with chronic kidney disease (CKD).
