Active clinical trials for "Kidney Diseases"

INTRODUCTION Psychological distress and reduced quality of life are prevalent in patients with chronic heart failure (CHF) and advanced chronic kidney disease (CKD). In addition, persons with CHF or CKD live with increased risk of primary or secondary complications associated with COVID-19, including mortality. International task force committees report that medical therapy combined with counselling for CHF and CKD self-care optimizes clinical outcomes. Digital health initiatives present an effective solution in light of the recent issue of declining patient attendance in essential outpatient appointments due to the increased risk of COVID-19 exposure. HYPOTHESES At study completion (up to 16 months), it is hypothesized that there will be a significant increase from baseline in the proportion of participants with clinically improved or sustained positive mental health. Additionally, greater engagement with the ODYSSEE-vCHAT program is expected to be linked with improved self-reported health- and wellbeing-related outcomes at months 4 and 8 and study completion (up to 16 months). RECRUITMENT Patients with CHF or CKD who are at least 18 years old were recruited from the University Health Network (UHN), Sunnybrook Hospital, Mount Sinai Hospital, The Ottawa Hospital, and the community. Accrual of the sample (N = 215) occurred over a 14-month period. DESIGN This is a single group, open label, pre-post study with assessments at baseline, months 4 and 8, and study completion (up to 16 months). ODYSSEE-vCHAT contacted subjects each week inviting them to participate or partake in digital counselling resources, chatrooms, and presentations with group discussions. Participation in supplemental mental health programs was monitored by self-report. ANALYSES A binomial logistic regression will evaluate if there is a greater proportion of participants with positive mental health at study completion. This analysis will assess if the proportion of participants with positive mental health at study completion (up to 16 months) is independently associated with ODYSSEE-vCHAT engagement (login minutes). General linear models will test secondary outcomes, adjusting for baseline assessments and potential covariates. Significance in all tests will be p < 0.05, 2-sided. Any unplanned analyses will be adjusted for using the Bonferroni procedure.

Background and importance: Hypertension is highly prevalent among Canadians with non-dialysis dependent chronic kidney disease (CKD). It is a modifiable risk factor for both cardiovascular (CV) events and CKD progression. Exercise is an effective strategy for blood pressure (BP) reduction in the general population but in people with CKD, hypertension is mediated by different causes (i.e. vascular stiffness, volume expansion) and it is unclear whether exercise will reduce BP in this population. Consequently, exercise resources are not offered in the routine multidisciplinary care of people with CKD and the prevalence of sedentary behaviour remains double that of the general population. The role of exercise in CKD management is also an important question for patients. From CIHR-supported workshops with patients, the role of lifestyle, such as exercise in CKD was a top research priority. Research aims: i.To determine the effect of exercise on mean ambulatory systolic blood pressure (SBP) in people with CKD compared to usual care. The investigators hypothesize that exercise training will significantly reduce BP compared to control. ii.To inform the design of a larger, multi-center trial evaluating the effect of exercise on the risk of CKD progression. Methods: A 160 participant, single center randomized trial of adults from Alberta Kidney Care North CKD clinics, Edmonton, Albert, Canada. Participants with an estimated glomerular filtration rate (eGFR) of 15-44 ml/min per 1.73m2 and SBP >130 mmHg will be randomized, stratified by eGFR (<30 versus ≥ 30) to an exercise intervention or usual care. The main outcome is the difference in 24-hour ambulatory SBP after eight weeks of exercise training between groups. Secondary outcomes include: BPs at eight and 24 weeks, dose of anti-hypertensives, aortic stiffness, CV-risk markers, CV fitness, 7-day accelerometry, quality of life, safety, and in an exploratory analysis, eGFR and proteinuria. The intervention is thrice weekly moderate intensity aerobic exercise supplemented with isometric resistance exercise, targeting 150 minutes per week and delivered over 24-weeks. Phase 1: one supervised weekly sessions and home-based sessions (eight weeks). Phase 2: home-based sessions (16 weeks). To detect a clinically important BP reduction of 5 mmHg between groups requires 128 patients (two sample t-test, alpha 0.05, beta 0.2, common standard deviation of 10 mmHg). Assuming 20% dropout requires 160 patients. For the primary outcome, the investigators will use a mixed linear regression model in which BP is regressed on group, baseline SBP and eGFR, and time point. Expected outcomes: The findings from this study will address a significant knowledge gap in hypertension management in CKD, inform care-delivery and the design of a larger study on CKD progression. This proposal aligns with priorities for both patients and decision makers: to identify the role of exercise in CKD management and to reshape the delivery of renal care so that it is more consistent with patient values and preferences.

Subjects who received tesevatinib in Study KD019-101 and completed 24 months of treatment will continue on the dose of tesevatinib they were receiving at 24 months on the KD019-101 study.

This is a prospective, randomized, multicenter, parallel, placebo-controlled, phase III study for evaluation of clinical efficacy and immunogenicity of drug Eritromax® - (rHuEPO Blau Farmacêutica S/A.) compared to Eprex® (Janssen-Cilag rHuEPO) for the treatment of patients with secondary anemia to chronic kidney disease (CKD), throughout the correction phase by assessing the change in hemoglobin levels.

Hypothesis: Routine clinical tests with feedback control based Epogen(Epo)/Venofer(Iron) protocol will improve Hemoglobin (Hgb) stability and increase the time that patients remain in target Objectives: Decreased variability of Hgb Increase the % of patients in target range c Increase in time that Hgb remains target range

Patient with liver failure waiting for liver transplantation are often hospitalized and commonly supported in an intensive care unit prior to surgery. These patients are sick, and in addition to the complications of a failing liver, other organs such as the kidneys often fail as well. As a consequence, these patients are at an increased risk for complications related to their kidney failure during their liver transplantation procedure. One potential method to diminish the risk of these complications is to provide dialysis support to these patients during their liver transplantation in the operating theater in the form of continuous renal replacement therapy (CRRT). While this is increasingly being performed and is theoretically appealing, there is very little information to support this practice. In addition, the use of CRRT during surgery is not entirely without risk. The investigators have performed two preliminary studies on the use of CRRT during liver transplantation and our data would strongly support the need to conduct further higher-quality studies to better evaluate its feasibility, safety and usefulness. Our proposed study is for a randomized trial comparing the use of CRRT during surgery with standard supportive care in sick patients with liver failure scheduled to receive a liver transplantation.

A Phase 2 glomerular filtration rate (GFR) measuring study of RTA 402 in Chronic kidney disease (CKD) patients with type 2 diabetes mellitus.

The study is designed to investigate the efficacy of renal nerve denervation in treating drug-resistant hypertension in patients with end stage renal disease.

Daprodustat has demonstrated an ability to effectively raise hemoglobin concentrations with lower erythropoietin (EPO) levels than those observed after administration of recombinant human erythropoietin (rhEPOs). Therefore, daprodustat has the potential to treat anemia of chronic kidney disease (CKD) with a lower cardiovascular (CV) risk than is observed with the rhEPOs. While the effect of rhEPOs on endothelial function has been assessed, to date the effect of daprodustat or other prolyl hydroxylase inhibitor (PHI) compounds on endothelial function has not. Therefore, the purpose of this study is to compare the effect of daprodustat to darbepoetin alfa on endothelial function by assessing FBF in participants with anemia of CKD by using venous occlusion plethysmography as a means to estimate the potential for daprodustat to have a lower risk of CV events as compared to rhEPO. This study will use a randomized, repeat dose, open label, parallel group design, in adult, not on-dialysis, male and female participants with anemia of CKD that are currently not treated with rhEPOs. The study will comprise of three study periods: a screening period starting up to 30 days prior to Day 1, a 42 day (6 week) treatment period, and a follow-up visit up to 14 days later. The total duration of participants involvement is up to 14 weeks (including screening and follow up visit). Approximately 50 participants will be randomized to either daprodustat or darbepoetin alfa.

The purpose of this study is to evaluate the effect of TRC101 on the progression of chronic kidney disease (CKD) and to evaluate the safety profile of TRC101 in CKD patients with metabolic acidosis.
