Kidney Disease, Chronic

This study is open to adults with chronic kidney disease at risk of progression. People with and without type 2 diabetes can take part in this study. The study is open to people who take other medicines called angiotensin converting enzyme inhibitors (ACEi) or angiotensin receptor blockers (ARB). People who already take empagliflozin or any other sodium-glucose cotransporter-2 inhibitor (SGLT2i) can also join. The study is also open to people who currently do not take any of these treatments. The purpose of this study is to find out whether a medicine called BI 690517 helps people with chronic kidney disease when taken in combination with a study medicine called empagliflozin. Worsening of kidney function increases the risk for kidney failure, cardiovascular disease, and heart disease. After a run-in period, during which participants are confirmed to be receiving clinically appropriate renin-angiotensin system blockade and are established on empagliflozin, they are randomly assigned (by chance) to 1 of 2 groups. One group receives BI 690517 tablets, and the other group receives placebo tablets. Placebo tablets look like BI 690517 but do not contain any medicine. Participants take 1 study tablet once a day, in addition to empagliflozin, for the duration of the study. The doctors document when participants experience worsening of their kidney disease, go to hospital due to heart failure, or die of cardiovascular problems during the study. The time to these events is compared between the 2 treatment groups to see whether the treatment works. The study continues until the required number of events have occurred which is about 3 to 4 years. During this time, participants visit the study site about 4 times within the first 6 months. Then they visit the study site every 6 months. At the visits, doctors regularly check participants' health, take blood and urine samples, measure blood pressure and weight, check kidney function, and take note of any unwanted effects.

This study aims to determine if GLP1RA is safe and tolerable in maintenance dialysis population, adherence, and feasibility of a larger definitive cardiovascular outcome trial in this population. Participants will be randomized 1:1 to either weekly subcutaneous semaglutide versus usual care and followed for 26 weeks.

The goal of this clinical trial is to learn whether a new regenerative treatment called AdiaVita, made from umbilical cord blood-derived stem cells and exosomes combined with glutathione, is safe and can help improve kidney function in adults with chronic kidney disease (CKD). In this condition, the kidneys gradually lose their ability to filter blood as well as they should. The main questions it aims to answer are whether AdiaVita plus glutathione improves kidney function better than control treatments, as measured by blood tests for estimated glomerular filtration rate (eGFR) and creatinine levels, and whether the treatment is safe with acceptable side effects. Researchers will compare three groups. One group will receive AdiaVita plus glutathione. A second group will receive glutathione plus a placebo for AdiaVita. The third group will receive placebos for both treatments. A placebo looks like the real treatment but contains no active ingredients. This will help determine if the full treatment works better than the controls. Approximately 100 adults aged 18 to 80 with stage 2 to 4 chronic kidney disease may participate. Participants will be randomly assigned to one of the three treatment groups. They will receive monthly intravenous infusions at the clinic for the first three months and apply a skin spray twice daily at home during that period. The study lasts 12 months total for each participant, with regular visits for blood tests, physical exams, and safety monitoring. Certain participants in the control groups may switch to the active AdiaVita treatment after three months if they meet safety criteria. This is a single-blind study, meaning participants will not know which treatment they receive. Participant safety is closely monitored by the research team and an independent board throughout the study.

The goal of this clinical trial is to understand the communication occurring between Black and Caucasian patients and their transplant providers during transplant evaluation consultations and assess relationships between these communicative elements and patient and provider factors, patient-reported outcomes and living donor transplant outcomes - living donor referrals, evaluations, and transplants. We will use these findings to inform the development of a communication skills training for transplant providers and test the impact of the training on providers' communication about live donor kidney transplants with Black and Caucasian patients and living donor transplant outcomes. The main questions it aims to answer are: * How does the use of the use of instrumental, relational and affective communication by patients and providers during the transplant consultation differ by patient and provider factors, patient-reported outcomes and patient ethnicity? * What elements of instrumental, relational and affective communication will be predictive of live donor kidney transplant (LDKT) process outcomes (LD inquiries and evaluations, and actual LDKTs)? Participants will be asked to complete brief surveys before and after the transplant consultation and to give permission for the consultation to be audiorecorded. This data will be used to develop a training to educate providers on the key communication factors predictive of LDKT process outcomes specific to Black and Caucasian patients, and provide guidance on their application during patient consultations. Researchers will then compare communication and patient-reported and LDKT process outcomes between trained and untrained providers to see whether the training has any effect on living donor inquiries and evaluations, and actual LDKTs.

This study in being conducted in men who have low testosterone and chronic kidney disease. The investigators will evaluate the effects of an oral testosterone preparation, JATENZO, on testosterone levels and hemoglobin (red blood cells).

The goal of this observational study is to learn more about how genes impact the risk of kidney disease. Anyone 18 or older living in the US is eligible, and a diagnosis of kidney disease is NOT required. Study participation is online, and it takes about 20 minutes to complete health surveys and request a saliva collection kit sent through US mail. In return, study participants may opt to receive information about their genetic ancestry at no cost.

The goal of this clinical trial is to compare protein supplements in patients with kidney failure on dialysis. The main questions it aims to answer are: * To determine whether the supplementation of egg white protein pudding in a population of individuals with kidney failure on dialysis is feasible. * To determine whether egg white protein pudding supplementation improves serum albumin similar to other standard nutritional supplements. * To determine the effects of the egg white protein pudding on frailty measures, dietary intakes and analytes in the blood. Participants will receive either the egg white pudding (experimental) or control (Ensure plus) at the end of their dialysis treatments 3-days per week for 12 weeks.

The autonomic nervous system (ANS) plays a crucial role in cardiovascular regulation by modulating heart rate in response to endogenous and environmental stimuli. Heart rate variability (HRV) analysis has been widely used as a non-invasive tool to assess autonomic function and the balance between sympathetic and parasympathetic activity. Although the physiological interpretation of some HRV parameters remains debated-particularly the low-frequency (LF) spectral component as an index of sympathetic activation-HRV remains an important method for evaluating autonomic cardiovascular control. Reduced HRV has been associated with adverse outcomes in several pathological conditions and physiologically declines with aging, mainly due to progressive neuronal loss at central and spinal levels. Among conditions characterized by autonomic dysfunction, cardiovascular autonomic neuropathy (CAN) represents a common complication of diabetes mellitus (DM) and metabolic syndrome. CAN, defined as impairment of autonomic control of the cardiovascular system, develops early in the disease course and is associated with increased mortality and a higher risk of cardiovascular and renal complications. Sodium-glucose cotransporter 2 inhibitors (SGLT2i), initially developed as glucose-lowering agents, have demonstrated significant cardiovascular and renal protective effects beyond glycemic control. Growing evidence suggests that these drugs exert sympathoinhibitory effects that may be beneficial not only in diabetic patients but also in conditions characterized by sympathetic overactivity. Preclinical and clinical studies have shown that SGLT2i influence autonomic regulation, including sympathetic control of renal function, with reported improvements in 24-hour blood pressure regulation and HRV parameters. Large randomized trials have further confirmed the cardioprotective effects of SGLT2i therapy. Studies such as EMBODY, EMPEROR-Reduced, and EMPEROR-Preserved have demonstrated improvements in HRV indices and significant reductions in cardiovascular death and hospitalization for heart failure, irrespective of diabetic status. Despite these findings, the mechanisms underlying these benefits remain incompletely understood. While reduced sympathetic activity has been proposed as a key mechanism, emerging evidence suggests that SGLT2i may also enhance vagal modulation. Therefore, the present study aims to investigate, in a larger population, the effects of SGLT2i therapy on sympathovagal balance using both spectral HRV parameters and additional indices, including the parasympathetic nervous system index (PNSi), sympathetic nervous system index (SNSi), and the Baevsky Stress Index.

An observational study capturing real world transplant patients in the post-operative setting aiming to further determine the utility of biomarkers to improve outcomes.

Chronic kidney disease (CKD) complicates many pathologies and the rapid increase in its prevalence constitutes a major public health concern. Whatever the cause of kidney failure, high protein consumption is a factor of progression to end-stage kidney disease. A low-protein (0.6 g/kg/d) or a very low-protein (0.3 g/kg/d) diet associated with supplementation with amino acids and/or keto acid analogues (KA) slows down renal function deterioration and prolongs the time before dialysis start. Difficulties in strict protein restriction implementation limit its use to a minority of CKD patients and are difficult to implement in real life. Recently KDOQI guidelines have recommended a dietary protein intake of 0.55 to 0.6 g/kg/d in CKD 3 to 5 non-diabetic patients "metabolically stable" and 0.6 to 0.8 g/kg/d in diabetic patients. However, the International Society of Renal Nutrition and Metabolism and the French guidelines about management of CKD propose to maintain a protein intake between 0.6 and 0.8 g/kg/d for all patients and as near as possible to 0.6 g/kg/d. This is because for a population, a mean value of 0.66 g/kg/d insures that 95% of patients are above 0.55 g/kg/d (the minimum requirement to avoid a negative nitrogen balance). Experimental studies and few clinical studies suggest a protective effect of KA supplementation on uremic sarcopenia. Interestingly this effect is also observed in patients with a protein intake of 0.6 to 0.8 g/kg/d and with a dose of KA reduced by half compared to the dose used with VLPD. Moreover, in a preliminary study, we found a nephroprotective effect of KA (1 tablet/5kg body weight) in patients with an average dietary protein intake of 0.7 g/kg/d suggesting a specific effect of KA beyond protein restriction. The hypothesis is therefore that KA treatment (1 tablet/10kg), together with a dietary protein intake between 0.6 and 0.8g/kg/d, prevent muscle mass loss in patients with stages 4 and 5 CKD. If these results were confirmed, this could expand the population that could benefit from KA supplementation.

This study will evaluate the effect of intravenous injection of umbilical cord tissue derived mesenchymal stem cells (UMSCs) on the improvement of renal function in patients with chronic kidney disease (CKD) at stage 3 or 4, with the change of estimated glomerular filtration rate (eGFR) as the primary endpoint, and other changes in renal function laboratory indicators, changes in other organ system function laboratory indicators, and adverse reaction events as secondary endpoints. This trial aims to further evaluate the efficacy and safety of UMCSs in CKD patients, and provide new insights into expanding the clinical treatment strategies, delaying the progression and improving the prognosis of CKD patients.

This is a phase IV multicentre adaptive single-blinded randomized clinical trial to evaluate if preemptively genotyping populations at pretransplant chronic kidney disease susceptible of receiving tacrolimus therapy is effective, cost-effective, and feasible within the Spanish National Health System when compared to the current standard of care. This trial is nested within the iPHARMGx master protocol.

The goal of this clinical trial is to predict the progression of chronic kidney disease by diuretic testing in patients with chronic kidney disease. The main questions it aims to answer are: Does a worse result of a diuretic test predict the progression of chronic kidney disease? If there is a comparison group: Researchers will compare the diuretic test in patients with chronic kidney disease to healthy participants to see if the results are different in a healthy kidney. Participants will undergo diuretic testing. This involves the administration of bumetanide and hydrochlorothiazide with subsequent blood and urine collections.

The goal of this clinical trial is to learn whether probiotic supplementation can slow disease progression in patients with moderate to severe chronic kidney disease (CKD). The trial will also assess the safety of probiotics in these patients. The main questions the study aims to answer are: Does probiotic supplementation improve kidney function by reducing serum creatinine levels and protein in urine? Does it reduce inflammation and metabolic imbalances in CKD patients? Does it affect gut microbiota composition and lower harmful toxins in the body? Is probiotic supplementation safe and well-tolerated in CKD patients? Participants will: Be randomly assigned to receive either probiotics or a placebo for 6 months. Have clinic visits every 6 months for checkups, blood tests, and urine tests. Be monitored for any side effects and changes in kidney function. Researchers will compare the probiotic group to the placebo group to determine whether probiotics are effective in slowing CKD progression.

Native Hawaiians (NH) are 9.5 times more likely to be on dialysis or need a kidney transplant compared to Whites. They have the highest end-stage kidney disease (ESKD) incidence rates in the nation, begin dialysis at younger ages (30-50 years), and one of the most under-studied racial/ethnic groups in chronic kidney disease (CKD) research. This project's outcome is to improve kidney disease follow-up among early stage NHs at high risk by aligning health equity with a culturally appropriate care coordination systems model.

The goal of this clinical trial is to learn if an intervention of a hospital pharmacist could help, dialysis patients managed his treatment. In a first time, the health literacy level will be assed. The main questions it aims to answer are: What is the impact of the clinical pharmacist intervention on the understanding level and management level of his treatment by the patient? Does the intervention of the pharmacist has an effect on the biologicals parameters of the patient? Researchers will compare a group with a pharmacist intervention VS a group without pharmacist intervention for dialysis patients.

The goal of this double-blinded, placebo-controlled, randomized, crossover study is to examine the effect of semaglutide, a glucagon-like peptide-1 receptor agonist (GLP-1RA), on renal hemodynamics and function in patients with type 2 diabetes mellitus (T2DM) and moderate chronic kidney disease (CKD). The study will determine the effects of semaglutide on: * Renal arterial blood flow, regional renal perfusion, and oxygenation * Activity of the renin-angiotensin-aldosterone system (RAAS) * The glomerular filtration rate (GFR) * Sodium excretion in urine * Blood pressure and heart rate
