A Study of Roxadustat to Treat Anemia in Children and Teenagers With Chronic Kidney Disease

Roxadustat is a licensed medicine to treat anemia in adults with chronic kidney disease (CKD). Anemia is a low level of red blood cells. Current treatment for anemia is to have injections of medicines called erythropoietin stimulating agents (also known as ESAs) to help the bone marrow make more red blood cells. These are often given together with iron. This treatment is also available to children and teenagers with CKD. However, there are some safety concerns with ESAs. Also, as roxadustat is taken orally, this may be another option for treating anemia in children and teenagers with CKD. In this study, children and teenagers with CKD and anemia will take roxadustat for up to 52 weeks to treat their anemia. The main aim of the study is to learn how roxadustat affects anemia in children and teenagers with CKD. This is an open-label study which means the children and teenagers in the study and the clinic staff know they will be taking roxadustat. In this study, the children and teenagers with CKD who need treatment for anemia can take part. Those currently being treated with an ESA will be switched to roxadustat. Those who have not been treated with an ESA can start on roxadustat straight away. All children and teenagers in the study will take roxadustat 3 times a week for up to 52 weeks (1 year). They will start on a fixed dose of roxadustat for 4 weeks. Blood samples will be taken regularly to check hemoglobin levels. The roxadustat dose may be changed if the blood levels of hemoglobin are too high, too low, or change too quickly. After 4 weeks the dose may be changed, if needed, to keep blood levels of hemoglobin in the blood to just below the normal range. Firstly, teenagers will take roxadustat. 10 teenagers will take their fixed dose of roxadustat for 4 weeks. They will give blood samples to help the researchers work out the most suitable dose for the rest of the teenagers in the study. When the rest of the teenagers start taking roxadustat at the most suitable dose for teenagers, 10 children will take roxadustat for 4 weeks. These 10 children will give blood samples to help the researchers work out the most suitable dose for the rest of the children in the study. Then, the rest of the children will take roxadustat at the most suitable dose for children. There will be many clinic visits during the study. Overnight hospital stays are not expected. There will be 1 visit every 2 weeks for the first 4 weeks of taking roxadustat, then every 4 weeks until the end of treatment. Finally there is 1 visit 4 weeks after treatment has finished. During most visits, the children and teenagers will have their vital signs checked (blood pressure, body temperature and heart rate). Fluid status (how much water is in the body) will also be checked for those who need dialysis. The children and teenagers will also have blood tests and the study doctors will check for any medical problems. The children and teenagers will have a medical examination before their first dose of roxadustat and again at about 24-week (6-month) and 52-week (13-month) visits. They will have an electrocardiogram (ECG) before their first dose of roxadustat and again at the 12-week, 24-week, 36-week, and 52-week visit. They will also have urine tests at the 4-week, 24-week and 52-week visits. At the 52-week visit, the children and teenagers will also have blood tests for hemoglobin and iron levels. The study doctors will also check for any medical problems.

Effect of Secukinumab on Cardiorenal Outcomes in Patients With Cardiorenal Metabolic Syndrome and Atherosclerotic Cardiovascular Disease

This is a prospective, randomized, open-label, parallel-controlled clinical trial to evaluate the efficacy and safety of targeted IL-17A inhibition with secukinumab on cardiovascular and renal endpoints in 100 patients with cardiorenal metabolic syndrome and atherosclerotic cardiovascular disease (ASCVD). Eligible subjects will be randomized 1:1 to receive either secukinumab 75 mg subcutaneous injection every 4 weeks for a total of 12 weeks plus standard guideline-directed medical therapy, or standard medical therapy alone. The primary endpoint is the time to first occurrence of 3-point major adverse cardiovascular events (MACE, including cardiovascular death, non-fatal myocardial infarction, or non-fatal stroke) over a 2-year follow-up period. Key indicators include estimated glomerular filtration rate (eGFR) and urine albumin-to-creatinine ratio (UACR) for renal outcome assessment.

Nicotinamide Riboside Supplementation in Chronic Kidney Disease

This study is testing whether a dietary supplement called nicotinamide riboside, (NR), can be used in adults with moderate chronic kidney disease. NR is a form of vitamin B3 that may help support cellular energy metabolism. The main goal of this study is to see whether it is feasible for people with chronic kidney disease to take NR daily, complete study visits, and follow the study procedures. The study will also explore whether NR chloride affects markers of mitochondrial health, small blood vessel function, and physical function. Participants will be randomly assigned to one of two treatment orders. One group will take NR first and placebo second. The other group will take placebo first and NR second. Placebo looks like NR but does not contain active NR. Each treatment period lasts 12 weeks, with an approximately 2-week washout period between treatments. Neither participants nor the study team will know which treatment participants are taking during each period. Study visits will include blood and urine collection, physical function testing, and noninvasive tests of small blood vessel function. The study will enroll up to 36 adults with moderate chronic kidney disease at the University of California, San Diego.

The NTU JO-SMART Study

This study recruits patients with coexisting obesity and knee osteoarthritis (KOA) to implement the NTU-JO Smart Program, an innovative intervention integrating AI-assisted community-based exercise with continuous glucose monitoring (CGM). The primary objective is to investigate whether this intervention can improve glycemic control in this comorbid population. Other outcome measures include the risk of total knee arthroplasty (TKA), body weight changes, pain intensity scores, bone mineral density (BMD), cognitive function, as well as the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Patient-Reported Outcomes Measurement Information System (PROMIS) scores, which reflect the patients' overall functional status. The project also sought to explore the long-term association of the NTU-JO Smart Program with the development of type 2 diabetes (T2D) and major renal events, thereby facilitating patient-centered early treatment.

Effects of Surgical, Percutaneous or Medical Treatments for Coronary Artery Disease on Renal Function: Long-Term Outcome. Cardiorenal-trial.

Background: Coronary artery disease (CAD) is treated with coronary artery bypass grafting (CABG), percutaneous coronary intervention (PCI), or optimized medical therapy (OMT). Their cardiovascular outcomes are well studied, but renal effects remain unclear. Objective: To evaluate long-term renal outcomes of different CAD treatment strategies. Methods: In this retrospective cohort from the MASS registry, patients with stable multivessel CAD and preserved ventricular function underwent OMT, CABG, or PCI. Annual creatinine was measured for ≥5 years, and eGFR calculated using CKD-EPI. The primary endpoint was change in renal function over time. Secondary endpoints included new-onset CKD, progression to advanced CKD, dialysis, and mortality. Analyses will use mixed-effects models and Cox regression. Results: Over 1,700 patients met inclusion criteria. Longitudinal follow-up enables robust comparison of renal trajectories across treatment groups. Conclusions: This trial highlights renal function as a primary outcome in CAD management, aiming to inform integrated strategies for patients with concurrent cardiovascular and renal risk.

Renal Impairment Study for Oral EC5026

The goal of this Phase 1 clinical trial is to assess single dose pharmacokinetics of oral EC5026 in a population with chronic kidney disease. The main questions it aims to answer are: 1. To determine if the PK of a single 8 mg dose of EC5026, administered orally, in adult participants with varying severity of CKD differs from age-matched healthy participants with normal kidney function. 2. To determine if a single 8 mg dose of EC5026, administered orally, in adult participants with varying severity of CKD is safe and well tolerated. Researchers will compare a single 8 mg dose of oral across participants with varying degrees of kidney function impairment (either normal kidney function, or stage 3b chronic kidney disease \[CKD\], or state 4/5 CKD). Participants will be asked to take a single oral dose of EC5026 and will be monitored with PK laboratory assessments and safety assessments (including physical exams, vital signs, electrocardiograms, and others).

A Study to Find Out How EMPAgliflozin is Tolerated and if it Helps Children and Adolescents With Chronic KIDNEY Disease (EMPA-KIDNEY® Kids)

This study is open to children aged 2 to 17 with chronic kidney disease (CKD). The purpose of this study is to find out if a medicine called empagliflozin helps children and adolescents with CKD. Other goals of the study are to find out how empagliflozin is tolerated and handled by the body in children and adolescents with CKD. Participants are put into 2 groups randomly, which means by chance. One group takes empagliflozin and the other group takes placebo. Placebo looks like empagliflozin but does not contain any medicine. Participants are twice as likely to be in the empagliflozin group. Participants take empagliflozin or placebo as tablets once a day for 6 months. After 6 months, participants in both groups take empagliflozin as tablets once a day for 1 year. Participants are in the study for a little over a year and a half. During this time, they visit the study site about 15 times and get at least 5 phone or video calls from the site staff. At the visits, the doctors take blood and urine samples from the participants. The doctors also regularly check participants' health and take note of any unwanted effects.

A Study to Test Whether Vicadrostat in Combination With Empagliflozin Helps People With Chronic Kidney Disease

This study is open to adults with chronic kidney disease (CKD) that is at risk of getting worse. People who have taken a specific type of medication for kidney disease called SGLT2 inhibitor within 1 month before the study or have certain health conditions cannot take part in this study. The purpose of this study is to find out whether a medicine called vicadrostat, used in combination with another medicine called empagliflozin, works in people with chronic kidney disease. In this study, participants are randomly assigned to one of two groups. Participants have an equal chance of being assigned to either group. In one group, participants take the 2 study medicines, vicadrostat and empagliflozin, every day for 3 months. In the other group, participants take placebo and empagliflozin for the first 1.5 months, and then they take vicadrostat and empagliflozin together for the next 1.5 months. The study medicines are taken orally as tablets. Placebo tablets look like vicadrostat tablets but do not contain any medicine. Participants are in the study for about 4.5 months. During this time, they visit the study site multiple times. Doctors regularly test kidney function by measuring specific proteins in the blood and urine. The results are compared between the two groups to see whether there are differences between starting the study medicines at the same time or one after the other. The doctors also regularly check participants' health and take note of any unwanted effects.

Assessing Outcomes of Enhanced Chronic Disease Care Through Patient Education and a Value-based Formulary Study

The purpose of this study is to determine the effect of two novel interventions; (1) a value-based formulary which eliminates copayment for selected high-value medications (proven to prevent heart attacks, stroke, and hospitalizations); and (2) a comprehensive patient education program aimed at lifestyle modification and optimal drug use, combined with relay of information on medication use, on the risk of adverse clinical outcomes (mortality, heart attack, stroke, need for coronary revascularization, and chronic disease related hospitalizations) in low-income seniors with chronic conditions over three years of follow-up or until March 31, 2021 (whichever comes first).

Vibration Massage, Static Stretching Exercise, Intradialytic Muscle Cramps and Stress

Chronic kidney disease (CKD) is characterised by kidney damage that persists for 3 months or longer or an estimated glomerular filtration rate (eGFR) below 60 mL/min/1.73 m² and is assessed in 6 categories. According to this categorisation, when stage 4 CKD progresses, patients are offered several options for renal replacement therapy. In the last stage of CKD, stage 5, renal replacement therapies including dialysis and kidney transplantation are used. Haemodialysis (HD) is a frequently used life-saving treatment method that removes harmful waste substances accumulated in the body, helps to maintain kidney function, provides fluid-electrolyte balance, prolongs life by managing uremic symptoms. Patients with ESRD are exposed to many health problems such as water-salt balance abnormalities, hypertension, hyperkalemia, metabolic acidosis, hyperphosphatemia, anaemia, cardiovascular disease. While the problems experienced are controlled with HD treatment, the treatment process and the continuation of life dependent on a machine cause life-threatening acute (hypotension, nausea, vomiting, muscle cramps, itching, pain, etc.) and chronic complications (pericarditis, hypertension, anaemia, hepatitis infections, etc.). In addition, due to these complications, HD patients may have problems that cannot be ignored such as deterioration in general health perception, sleep disturbance, anxiety, depression, stress, and difficulties in fulfilling responsibilities due to psychosocial problems. Intradialytic muscle cramp, which develops acutely during HD and is experienced at least once by patients, frequently manifests as involuntary muscle contractions in the lower extremities. The aetiology of intradialytic muscle cramp includes hypotension, electrolyte mineral disorders, high ultrafiltration (UF), excess weight gain between two HDs and carnitine deficiency. In the pharmacological treatment of this complication, which should be managed acutely, intravenous saline solution and hypertonic glucose administration are prominent, but high-quality evidence on the effectiveness of these treatments is needed. While the results of interventions such as aromatherapy, reflexology, massage, stretching-relaxation exercises, hot-cold applications etc. in intradialytic muscle cramp have been reached, the lack of evidence for vibration massage is striking. Management of intradialytic muscle cramp is important for the HD adequacy of patients and failure to manage it may lead to fatal complications such as hypertension, hypervolemia, pulmonary oedema and left ventricular failure due to inadequate HD sessions. It has also been reported that sleep and quality of life are adversely affected in cases where intradialytic muscle cramp cannot be managed; shortening of one HD session per week leads to increased mortality rates, depression and anxiety levels and stress. Salivary cortisol is a useful biomarker often used as a marker of psychological stress. Salivary cortisol levels peak approximately 20 minutes after an acute stress event. Massage, which is among independent nursing interventions, is a manipulation that provides physical and psychological relaxation by mechanically stimulating muscle tissues. During massage, nurses can apply euphlorage, petrissage, friction, tapotman and vibration. Vibration massage is applied to improve muscle atrophy and bone density caused by microgravity and immobilisation. Static stretching exercise, another intervention in intradialytic muscle cramp management, reduces muscle stiffness and tension by increasing muscle flexibility and range of motion by stimulating neural activities. These exercises reduce the risk of injury to joints, muscles and tendons by stimulating the formation of chemicals that allow the connective tissue to move easily and are recommended for the prevention of muscle cramps.

A Natural History Study of Metabolic Sizing in Health and Disease

Background: Scientists have long used simple measures (such as height and weight) to estimate how much a person s body uses food (calories) as energy, as commonly called the metabolic rate. But metabolism varies among people with similar body sizes. Scientists now believe the old formulas for estimating metabolic rates may not work well for all people. Researchers want to find more accurate ways to measure a person s metabolism. Objective: This natural history study will examine the relationships between metabolism, body composition, and body surface area in a wide range of people. Eligibility: Healthy children and adults aged 2 years or older. Also, people aged 2 years or older with conditions that may alter metabolism. These may include diabetes, obesity, renal disease, or cancer. Design: Participants will spend 2 days and 1 night in the hospital. They will provide a medical history and answer questions about their activity levels, the foods they eat, and their lifestyle. They will also eat a special diet. Participants will undergo many tests: They will lie in a bed with a clear hood covering their head for 30 to 45 minutes to measure the gases in their breath. They will lie on a padded table for about 15 minutes while their body is scanned. They will stand on a platform while a 3D scanner measures their body. They will have a test to measure how fast an electric signal moves through their body. They will grip an instrument to measure the strength of their hands. They will drink salty water and provide blood and urine samples. Participants may be invited to return for these 2-day visits up to 8 times per year. Return visits must be at least 2 weeks apart.

An Observational Study to Learn More About How Safe Finerenone is and How Well it Works in People With Chronic Kidney Disease and Type 2 Diabetes in Routine Medical Care in the United States

This is an observational study in which data from people with chronic kidney disease (CKD) and Type 2 diabetes mellitus (T2D) are collected and studied. In observational studies, only observations are made without participants receiving any advice or any changes to healthcare. CKD is a long-term condition in which the kidneys' ability to work properly gradually decreases over time. It is common in people with Type 2 diabetes mellitus (T2D), a condition in which glucose levels rise in the blood. People who have T2D and CKD may also develop heart disease over time. The study drug, finerenone, is already approved for doctors to prescribe to people with CKD and T2D in the US. It blocks the activity of a protein involved in worsening kidney function. The participants in this study are allowed to take finerenone as part of their regular care from their doctors. The main purpose of the study is to learn about how safe finerenone is and how well it works in people with CKD and T2D in routine medical care. To do this, researchers will collect information about the time to first occurrence of any of the following heart-related problems for participants in the US who are taking finerenone and those who are not taking it: * Heart attacks * Hospitalization due to heart failure The data will come from the electronic healthcare records of people with CKD and T2D in the US who are allowed to take finerenone after July 2021. Researchers will track participants' data and will follow them until the occurrence of heart-related problems, the participant's data is no longer available, there is a change in the participant's treatment strategy, or the end of the study. In this study, only available data from routine care are collected. No visits or tests are required as part of this study.

Subjects will either be enrolled on a virtual weight management program or continue their usual care.

Development and Validation of a Machine Learning Model for Differentiating Diabetic Kidney Disease and Non-Diabetic Kidney Disease in Type 2 Diabetes

This multicenter retrospective observational study aims to develop and validate an interpretable machine learning model for differentiating diabetic kidney disease (DKD) from non-diabetic kidney disease (NDKD) in patients with type 2 diabetes mellitus. Clinical, laboratory, and pathological data from biopsy-confirmed patients were collected from 14 medical centers in China. Multiple machine learning algorithms were evaluated and externally validated. The final model was implemented as a web-based clinical decision support tool.

An Observational Study, Called FINEXPLORER, to Learn More About How Well Finerenone Works in Adults in Spain With Chronic Kidney Disease (CKD) Linked to Type 2 Diabetes, by Looking at Changes in a CKD Risk Score

This is a prospective observational study in which data from people with chronic kidney disease (CKD) associated with type 2 diabetes (T2D) who will be receiving finerenone are collected and analyzed. Chronic kidney disease (CKD) is common in people with type 2 diabetes. It can get worse over time and may lead to kidney failure and heart problems. Doctors often track kidney health using blood and urine tests, including the estimated glomerular filtration rate (eGFR) and the urine albumin-to-creatinine ratio (UACR). There are also tools that combine routine laboratory test results to estimate a person's risk of their kidney disease getting worse. One of these tools is called the Klinrisk model. The study drug, finerenone, is already approved for doctors to prescribe to patients with CKD associated with T2D and albumin in the urine. Finerenone works by blocking the mineralocorticoid receptor, a protein involved in inflammation and scarring in the kidneys and heart. The study drug, finerenone, is a non-steroidal mineralocorticoid receptor modulator that aims to reduce harmful kidney and heart changes. The main purpose of this study is to determine whether the Klinrisk score improves after 2 years of treatment with finerenone in adults with CKD associated with T2D who are treated in routine care. To achieve this, researchers will collect data on: * Clinical characteristics of participants, including their medical history related to CKD and T2D. * Variables used to assess the CKD progression, such as eGFR, UACR, and Blood Urea Nitrogen (BUN). * Participants' glucose, hemoglobin and potassium levels. The study will also monitor any medical problems (known as adverse events) that participants may experience during the study. All adverse events will be recorded, regardless of whether they are related to the treatment. Data will be collected from April 2026 to April 2029 and will cover a period of up to 24 months per participant. Data collection will occur over 5 visits that coincide with routine clinical care: inclusion, follow-up visits at 6, 12, and 18 months (±1 month), and a final visit at 24 months (±1 month).
