The REnal Patients COVID-19 VACcination Immune Response (RECOVAC IR) Study

Rationale: COVID-19 is associated with severely increased morbidity and mortality in patients with severely impaired kidney function, on dialysis or alive with a kidney transplant. Therefore, effective SARS-CoV-2 vaccination would be of great clinical importance in these patients. However, SARS-CoV-2 vaccination studies have excluded patients with chronic kidney disease (CKD) so-far. Objective: To assess the efficacy and safety of SARS-CoV-2 vaccination in patients with CKD stages 4/5, on dialysis or alive with a kidney transplant as compared to controls. Study design: prospective, controlled multicenter study Study population: 175 patients with CKD stages 4/5 (eGFR < 30 ml/min/1.73m2), 175 on dialysis , 300 alive with a kidney transplant and 200 controls (partners or sibblings of patients) Intervention: SARS-CoV-2 vaccination according to standard of care. Blood will be drawn at 4 different time points (baseline and at day 28, month 6 and year 1 after vaccination). Main study parameters/endpoints: The primary endpoint is the antibody based immune response on day 28 after the second vaccination. Participants will be classified as responders or non-responders. The definition of response will be based on the latest available data from the pivotal studies and will be defined prior to data analyses and the first database lock. The percentage of responders of each patient cohort will be compared with the percentage responders in the control group. Safety is a secondary endpoint which will be reported in terms of percentage of solicited local and systemic adverse events (AEs)graded according to severity. Other secondary endpoints include longevity of the immune response at 6 and 12 months and levels of SARS-CoV-2 specific T and B cell responses.

Carriage Clearance of Emerging Highly Resistant Bacteria in Chronic Dialysis Patients

The propias, and more recently the update of the recommendations relating to the control of the spread of bacteria highly resistant to emerging antibiotics issued by the High Council of Public Health (December 2019), recommend the implementation of measures to maintain the rate of Carbapenemase-producing Enterobacteriaceae (EPC) such as Klebsiella pneumoniae (K. pneumoniae) isolated from bacteremia in healthcare establishments in France at less than 1%, and that of Vancomycin Resistant Enterococcus (VRE) belonging to Enterococci Resistant to Glycopeptides (ERG) such as Enterococcus faecium isolated from bacteremia in health establishments in France at less than 1% also. At the same time, the prevalence of colonized patients is increasing. One of the recommended measures concerns the fight against cross transmission. Due to the high technicality of the treatments, the risks of cross-transmission are very high and present at each stage of the dialysis procedure. Screening and isolation of patients colonized with emerging Highly Resistant Bacteria (BHRe) is essential to avoid their spread and the risk of infection with these germs. Screening is done using rectal swabs. If the patient is found to be a carrier of BHRe, he should be isolated. Isolation is made more difficult in the hemodialysis room due to their architectural configuration, the organization of care and the chronicity of the patients. Patients have a monthly sample. The isolation is allowed after obtaining six consecutive negative rectal swabs, the number of which has been arbitrarily defined. Indeed, the negativation of the samples does not confirm the disappearance of the carriage (that is to say the presence of BHRe), hence the need to repeat them. Persistence of colonization at a rate below the detection limit is possible. With for corollaries: Isolation which could be lifted more quickly in the event of real disappearance of the strain since the investigators know that a prolonged period of isolation can lead to a loss of opportunity for the patient and the investigators know its impact for the patient, on the operation of the service and its cost, with in particular the increase in withdrawals. Isolation lifted too early in the event of persistent carriage with risk of secondary transmission. The interest of this study is to determine the clearance of the carriage of BHRe, i.e. their disappearance, in the chronic dialysis patient and to define, secondly, the factors associated with the prolonged carriage corresponding to the presence of bacteria for more than 3 months. , and elements of answer concerning the early disappearance of the EPC in the event of co-colonization by ERG and EPC. The follow-up of this carriage for 1 year will make it possible to evaluate the relapse corresponding to the reappearance of the bacteria previously identified, the recolonization corresponding to the acquisition of a new BHR, or the reinfection corresponding to an infection with a new highly resistant bacterium.

A Trial of Bardoxolone Methyl in Patients With CKD at Risk of Rapid Progression (MERLIN)

This multi-center, randomized, double-blind, placebo-controlled, Phase 2 trial will study the safety, tolerability, and efficacy of bardoxolone methyl in qualified patients with CKD due to multiple etiologies at risk of rapid disease progression. Approximately 70 patients will be enrolled and randomized 1:1 to either bardoxolone methyl or placebo. Patients with CKD secondary to varying etiologies will be enrolled from age 18-70 years with eGFR ? 20 to < 60 mL/min/1.73 m2, and other risk factors for rapid progression of kidney disease. The maximum target dose will be determined by baseline proteinuria status. Patients with baseline urine albumin to creatinine ratio (UACR) ? 300 mg/g will be titrated to a maximum dose of 20 mg, and patients with baseline UACR > 300 mg/g will be titrated to a maximum dose of 30 mg. Qualified patients will be randomized 1:1 to receive either bardoxolone methyl or placebo once daily (preferably in the morning) throughout a 12-week dosing period. Patients in the study will follow the same visit and assessment schedule. Patients will be assessed during treatment at Day 1, Weeks 1, 2, 4, 6, 8, and 12 and by telephone contact on Days 3, 10, 21, 31, 35, and 45. Date of last dose and the end-of-treatment assessments mark the end of the treatment period. Patients will not receive study drug during a 5-week off-treatment period between Weeks 12 and 17. The off-treatment (OT) period includes 5 visits requiring various assessments to characterize eGFR from the time of study drug discontinuation through Day 35 off-treatment.

Dapagliflozin in Non-diabetic Stage IV CKD

As chronic kidney disease (CKD) continues to increase worldwide, along with the demand for related life-saving therapies, the financial burden of CKD will place an increasing drain on health care systems. Experimental studies showed that glomerular capillary hypertension and impaired sieving function with consequent protein overload play a pathogenic role in the progression of CKD. Consistently, human studies show that proteinuria is an independent predictor of progression and that its reduction is renoprotective. At comparable BP control, inhibitors of the renin-angiotensin system (RAS), including angiotensin converting enzyme (ACE) inhibitors and angiotensin II receptor blockers (ARBs), more effectively than non-RAS inhibitor therapy reduce proteinuria, slow progression to ESRD, and even improve the kidney function achieving disease regression in some cases. In participants with diabetes, RAS inhibitors delay the onset of microalbuminuria and its progression to macroalbuminuria, and ACE inhibitors may reduce the excess cardiovascular mortality associated with diabetic renal disease. In addition to RAS inhibitors, however, multimodal approaches including lifestyle modifications and multidrug therapy will be required in most cases to optimize control of the several risk factors for CKD and related cardiovascular morbidity. Novel medications, including proximal tubular sodium - glucose co-transporter -2 (SGLT2 inhibitors - that ameliorate glomerular hyperfiltration and proteinuria and slow renal disease progression in type 2 diabetes by mechanisms apparently independent of improved metabolic control - might help further improve the cost-effectiveness of renoprotective interventions even in non-diabetic CKD. This phase 2, prospective, randomized, cross over, placebo-controlled trial will primarily aim to assess whether the SGLT2 inhibitor dapagliflozin ameliorates hyperfiltration and reduces proteinuria as compared to placebo in patients with non-diabetic CKD, with particular focus on those at highest risk of progression to end stage kidney disease (ESKD) because of severe renal insufficiency (Stage IV CKD) and proteinuria (>0.5 g/24 hours).
