Active clinical trials for "Renal Insufficiency"

This study used a single-dose, open design to compare the pharmacokinetics of subjects with mild, moderate and severe renal insufficiency and end-stage renal disease and subjects with normal renal function.

A prospective, randomised, open-labelled, multi-center study. The aim of the Steno 1 study is to test multifactorial intervention in individuals with type 1 diabetes at high risk of CVD with ambitious treatment targets. We will include 2000 participants. Follow-up is 5 years.

RBC transfusion (RBCT) after kidney transplantation(KT) is about 50%. Anemia is common after kidney transplant surgery due to intraoperative blood loss, delayed graft function, and side effects of immunosuppressive drugs. However, due to exposure to non-self human leukocyte antigens (HLA) from blood transfusion, there is a risk of sensitization to HLA through the production of anti-HLA antibodies. In renal transplant patients, exposure to non-self HLA antigens due to RBCT can lead to the generation of donor-specific antibodies (DSA) against renal allograft donors. Patients who have undergone KT are frequently exposed to RBCT, and immunologic damage resulting from this can be an important cause of loss of graft kidney function. Therefore, there should be a more careful review of the risk associated with RBCT on KT recipients. Of the 16,191 Koreans who underwent KT between 2008 and 2017, 59.7% received transplant-related blood transfusions. As a result of analyzing 13,871 Koreans who underwent KT between 2007 and 2015, the overall graft failure rate was 15.5%, and the hazard ratio of survival rate according to RBCT before and after KT increased as the amount of transfusion increased. RBCT before and after KT was independently associated with graft failure and death. Therefore, research on treatment methods that can effectively reduce blood transfusion in transplant patients is absolutely necessary. About 30-60% of patients undergoing major surgery show preoperative anemia, which causes blood transfusions, complications during hospitalization, prolonged hospitalization, and delayed recovery. The most common cause of anemia is iron deficiency. In particular, an increase in hepcidin, a major regulator of iron metabolism, reduces intestinal iron absorption and promotes iron sequestering by macrophages, resulting in a state of functional iron deficiency. Therefore, oral iron intake as a treatment for anemia in surgical patients is not effective. Although the safety and clinical superiority of high-dose intravenous iron therapy have been demonstrated in patients with chronic renal failure, the effect of this drug on blood transfusion of pre- and post-kidney transplant surgery has not been studied. Therefore, this study aims to verify the effectiveness and stability of the combined administration of intravenous(IV) iron and erythropoiesis-stimulating agents(ESA) before and after KT for patients who perform KT for end-stage kidney disease(ESKD). The investigators will analyze hemoglobin, transferrin saturation, ferritin changes, and transfusion requirements according to the combined administration of IV iron and ESA before and after surgery of kidney transplant patients. Also, the investigators evaluate whether a treatment combining IV iron and ESA will be possible as an alternative blood transfusion treatment and its effect on the clinical prognosis of KT recipients. In particular, the effect on the function of the graft kidney, immunological outcomes-DSA, antibody-mediated rejection, and survival rate will be analyzed. Also, the investigators will analyze the change in expression of hepcidin and oxidative stress markers before and after kidney transplantation and the mechanism of expression according to the combined administration of IV iron and ESA. This study is a multicenter(including 3 centers), open-label, prospective, and randomized clinical trial. 302 patients undergoing living-donor KT for ESKD are randomly assigned in a 1:1 ratio to an experimental group actively using IV iron and ESA, and a control group receiving conventional anemia treatment for 42 months from the time of IRB approval. Participants selected for the experimental group will be given a total of 1000 mg of IV Monofer(iron isomaltoside); each 200 mg dose on 28, 21, and 7 days before kidney transplantation, on the day of surgery, and 7 days after surgery. In the case of ESA, it is freely used according to the criteria up to 7 days before transplantation and subcutaneously injected with 120 mcg of Mircera(methoxy polyethylene glycol-epoetin beta) between 7 days before surgery and a day before surgery. In the control group, IV Monofer is administered only 28 days before surgery according to the set criteria. Mircera is also freely used in the control group according to the criteria up to 7 days before KT but not used between 7 days before surgery and a day before surgery.

The purpose of this study is to assess how fast IBI362 gets into the blood stream and how long it takes the body to remove it in participants with impaired kidney function compared to healthy participants.

The purpose of this study is to find substances in the blood and urine that indicate that a person has kidney damage. It will identify proteins found only in patients with acute kidney failure but not in normal healthy people or in patients with volume depletion. Adults and children who are at least 3 years old who fall into one of the following four categories may be eligible for this study: Are healthy and have normal kidney function Have volume depletion (this condition differs from acute kidney failure in that it is easily treated with fluids) Are at high risk of kidney failure Have acute kidney failure (kidney shutdown) All study participants will have a history and physical examination. Up to four blood samples of 3 tablespoons each will be taken for laboratory analysis. Urine will be collected for analysis and to measure urine output. The participants length of stay in the study varies. People with normal kidney function will be in the study for 1 day and patients with volume depletion will be studied 3 days. The length of hospitalization of patients at high risk of kidney failure or in acute kidney failure will depend on the patient s condition and medication requirements. The results of this study may lead to the development of earlier and more accurate methods for diagnosing acute kidney failure. With earlier detection, treatment could be started earlier, possibly preventing further damage and helping recovery of injury that has already occurred.

This is a multicenter, nonrandomized, open-label, parallel controlled Phase I clinical study to evaluate the Pharmacokinetics, Safety and Tolerability of SIM0417 combined with ritonavir after a single dose in subjects with mild and moderate renal impairment, moderate hepatic impairment, normal renal function, and normal hepatic function. It is divided into Part A (subjects with mild/moderate renal impairment and subjects with normal renal function) and Part B (subjects with moderate hepatic impairment and subjects with normal hepatic function).

Chronic kidney disease (CKD) consists of kidney damage and progressive and irreversible loss of kidney function. The aim of this study is to evaluate the acute effect of different doses of photobiomodulation therapy on quadriceps isometric muscle strength, pain and muscle fatigue of lower limbs and to establish the ideal dose for patients with CKD on hemodialysis. Patients will be submitted to application of photobiomodulation therapy in the quadriceps muscle. Immediately after, the maximum isometric strength test of the quadriceps will be performed.

The mismatch between organ supply and demand results in the deaths of thousands of Americans each year. Our research group aims to solve this unmitigated health care crisis by translating advances in xenotransplantation to humans and expanding organ supply in a sustainable fashion using genetically modified pigs as a source of organs. We propose here a phase I clinical trial of porcine kidney xenotransplantation into 20 people with end-stage kidney disease. Source donor animals are pigs with 10 gene edits (10-GE) which attenuate immunologic harm to the kidney xenograft. 10-GE pigs are housed in a designated pathogen-free facility within 30 minutes of the transplantation center. Xenotransplantation procedures follow conventional practices currently employed in allotransplantation and comply with multiple regulatory standards to ensure ethical treatment of research subjects and source animals. Recruitment and xenotransplantation will occur over 5 years with study follow-up extending 1 year after xenotransplantation. Primary outcome variables surround patient safety, such as patient survival and the rate of zoonotic disease transmission. Secondary outcome variables include commonly used metrics of graft survival and function.

This research study is for people who have been waiting for a kidney transplant for at least one year, and who have a cPRA of 99.5% or higher. Having a cPRA of 99.5% or higher means that your immune system would reject 99.5% of kidneys available for transplant. The study will test whether new products called Chimeric Antigen Receptor T Cells (CAR T Cells), when given with chemotherapy, is safe and will reduce cPRA. The main study will last up to 2 years: Participants will have up to 30 clinic or hospital visits over a one-year period. If a transplant takes place, there will be 9 more visits after transplant. Long term follow up is required by the Food and Drug Administration (FDA) for 15 years after receiving CAR T cell. The primary objective is to evaluate the safety and feasibility of administering CART BCMA + huCART-19 following lymphodepletion, including determination of optimal tolerated regimen (OTR) and/or recommended phase 2 regimen, according to the incidence of dose limiting toxicity (DLT) in highly sensitized patients awaiting kidney transplant.

The primary aim of the present study was to examine the haemodynamic changes in primary hypertension and secondary hypertension (renal diseases, endocrine diseases, obesity-associated hypertension) with a non-invasive haemodynamic measurement protocol utilizing radial pulse wave analysis and whole-body impedance cardiography in both supine position and during head-up tilt. For comparison, haemodynamics of subjects with chronic fatigue syndrome will also be recorded.
