Glucagon-like peptide-1 receptor agonists modestly reduced blood pressure among patients with and without diabetes mellitus: A meta-analysis and meta-regression. Diabetes Obes Metab 2024; 26:2209-2228. [PMID: 38505997 DOI: 10.1111/dom.15529] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2024] [Revised: 02/12/2024] [Accepted: 02/13/2024] [Indexed: 03/21/2024]
Abstract
AIM The cardiovascular benefits provided by glucagon-like peptide-1 receptor agonists (GLP-1RAs) extend beyond weight reduction and glycaemic control. One possible mechanism may relate to blood pressure (BP) reduction. We aim to quantify the BP-lowering effects of GLP1-RAs. METHODS A comprehensive database search for placebo-controlled randomized controlled trials on GLP-1RA treatment was conducted until December 2023. Data extraction and quality assessment were carried out, employing a robust statistical analysis using a random effects model to determine outcomes with a mean difference (MD) in mmHg and 95% confidence intervals (CIs). The primary endpoint was the mean difference in systolic BP (SBP) and diastolic BP. Subgroup analyses and meta-regressions were done to account for covariates. RESULTS Compared with placebo, GLP-1RAs modestly reduced SBP [semaglutide: MD -3.40 (95% CI -4.22 to -2.59, p < .001); liraglutide: MD -2.61 (95% CI -3.48 to -1.74, p < .001); dulaglutide: MD -1.46 (95% CI -2.20 to -0.72, p < .001); and exenatide: MD -3.36 (95% CI -3.63 to -3.10, p < .001)]. This benefit consistently increased with longer treatment durations. Diastolic BP reduction was only significant in the exenatide group [MD -0.94 (95% CI -1.78 to -0.1), p = .03]. Among semaglutide cohorts, mean changes in glycated haemoglobin and mean changes in body mass index were directly associated with SBP reduction. CONCLUSION Patients on GLP-1RA experienced modest SBP lowering compared with placebo. This observed effect was associated with weight/body mass index reduction and better glycaemic control, which suggests that BP-lowering is an indirect effect of GLP-1RA and unlikely to be responsible for the benefits.

Abstract
BACKGROUND Patients with type 2 diabetes and chronic kidney disease are at high risk for kidney failure, cardiovascular events, and death. Whether treatment with semaglutide would mitigate these risks is unknown. METHODS We randomly assigned patients with type 2 diabetes and chronic kidney disease (defined by an estimated glomerular filtration rate [eGFR] of 50 to 75 ml per minute per 1.73 m2 of body-surface area and a urinary albumin-to-creatinine ratio [with albumin measured in milligrams and creatinine measured in grams] of >300 and <5000 or an eGFR of 25 to <50 ml per minute per 1.73 m2 and a urinary albumin-to-creatinine ratio of >100 and <5000) to receive subcutaneous semaglutide at a dose of 1.0 mg weekly or placebo. The primary outcome was major kidney disease events, a composite of the onset of kidney failure (dialysis, transplantation, or an eGFR of <15 ml per minute per 1.73 m2), at least a 50% reduction in the eGFR from baseline, or death from kidney-related or cardiovascular causes. Prespecified confirmatory secondary outcomes were tested hierarchically. RESULTS Among the 3533 participants who underwent randomization (1767 in the semaglutide group and 1766 in the placebo group), median follow-up was 3.4 years, after early trial cessation was recommended at a prespecified interim analysis. The risk of a primary-outcome event was 24% lower in the semaglutide group than in the placebo group (331 vs. 410 first events; hazard ratio, 0.76; 95% confidence interval [CI], 0.66 to 0.88; P = 0.0003). Results were similar for a composite of the kidney-specific components of the primary outcome (hazard ratio, 0.79; 95% CI, 0.66 to 0.94) and for death from cardiovascular causes (hazard ratio, 0.71; 95% CI, 0.56 to 0.89). The results for all confirmatory secondary outcomes favored semaglutide: the mean annual eGFR slope was less steep (indicating a slower decrease) by 1.16 ml per minute per 1.73 m2 in the semaglutide group (P<0.001), the risk of major cardiovascular events 18% lower (hazard ratio, 0.82; 95% CI, 0.68 to 0.98; P = 0.029), and the risk of death from any cause 20% lower (hazard ratio, 0.80; 95% CI, 0.67 to 0.95, P = 0.01). Serious adverse events were reported in a lower percentage of participants in the semaglutide group than in the placebo group (49.6% vs. 53.8%). CONCLUSIONS Semaglutide reduced the risk of clinically important kidney outcomes and death from cardiovascular causes in patients with type 2 diabetes and chronic kidney disease.

Real-World Impact of Blood Pressure Control in Patients With Apparent Treatment-Resistant or Difficult-to-Control Hypertension and Stages 3 and 4 Chronic Kidney Disease. Am J Hypertens 2024; 37:438-446. [PMID: 38436491 PMCID: PMC11094384 DOI: 10.1093/ajh/hpae020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 02/02/2024] [Accepted: 02/26/2024] [Indexed: 03/05/2024] Open
Abstract
BACKGROUND Chronic kidney disease (CKD) is a common comorbidity in patients with apparent treatment-resistant hypertension (aTRH). We assessed clinical outcomes, healthcare resource utilization events, and costs in patients with aTRH or difficult-to-control hypertension and stage 3-4 CKD with uncontrolled vs. controlled BP. METHODS This retrospective cohort study used linked IQVIA Ambulatory EMR-US and IQVIA PharMetrics Plus claims databases. Adult patients had claims for ≥3 antihypertensive medication classes within 30 days between 01/01/2015 and 06/30/2021, 2 office BP measures recorded 1-90 days apart, ≥1 claim with ICD-9/10-CM diagnosis codes for CKD 3/4, and ≥1 year of continuous enrollment. Baseline BP was defined as uncontrolled (≥130/80 mm Hg) or controlled (<130/80 mm Hg) BP. Outcomes included risk of major adverse cardiovascular events plus (MACE+; stroke, myocardial infarction, heart failure hospitalization), end-stage renal disease (ESRD), healthcare resource utilization events, and costs during follow-up. RESULTS Of 3,966 patients with stage 3-4 CKD using ≥3 antihypertensive medications, 2,479 had uncontrolled BP and 1,487 had controlled BP. After adjusting for baseline differences, patients with uncontrolled vs. controlled BP had a higher risk of MACE+ (HR [95% CI]: 1.18 [1.03-1.36]), ESRD (1.85 [1.44-2.39]), inpatient hospitalization (rate ratio [95% CI]: 1.35 [1.28-1.43]), and outpatient visits (1.12 [1.11-1.12]) and incurred higher total medical and pharmacy costs (mean difference [95% CI]: $10,055 [$6,741-$13,646] per patient per year). CONCLUSIONS Patients with aTRH and stage 3-4 CKD and uncontrolled BP despite treatment with ≥3 antihypertensive classes had an increased risk of MACE+ and ESRD and incurred greater healthcare resource utilization and medical expenditures compared with patients taking ≥3 antihypertensive classes with controlled BP.

Identification and outcomes of KDIGO-defined chronic kidney disease in 1.4 million U.S. Veterans with heart failure. Eur J Heart Fail 2024. [PMID: 38700246 DOI: 10.1002/ejhf.3210] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Revised: 02/09/2024] [Accepted: 03/10/2024] [Indexed: 05/05/2024] Open
Abstract
AIMS According to the Kidney Disease: Improving Global Outcomes (KDIGO) guideline, the definition of chronic kidney disease (CKD) requires the presence of abnormal kidney structure or function for >3 months with implications for health. CKD in patients with heart failure (HF) has not been defined using this definition, and less is known about the true health implications of CKD in these patients. The objective of the current study was to identify patients with HF who met KDIGO criteria for CKD and examine their outcomes. METHODS AND RESULTS Of the 1 419 729 Veterans with HF not receiving kidney replacement therapy, 828 744 had data on ≥2 ambulatory serum creatinine >90 days apart. CKD was defined as estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m2 (n = 185 821) or urinary albumin-to-creatinine ratio (uACR) >30 mg/g (n = 32 730) present twice >3 months apart. Normal kidney function (NKF) was defined as eGFR ≥60 ml/min/1.73 m2, present for >3 months, without any uACR >30 mg/g (n = 365 963). Patients with eGFR <60 ml/min/1.73 m2 were categorized into four stages: 45-59 (n = 72 606), 30-44 (n = 74 812), 15-29 (n = 32 077), and <15 (n = 6326) ml/min/1.73 m2. Five-year all-cause mortality occurred in 40.4%, 57.8%, 65.6%, 73.3%, 69.7%, and 47.5% of patients with NKF, four eGFR stages, and uACR >30mg/g (albuminuria), respectively. Compared with NKF, hazard ratios (HR) (95% confidence intervals [CI]) for all-cause mortality associated with the four eGFR stages and albuminuria were 1.63 (1.62-1.65), 2.00 (1.98-2.02), 2.49 (2.45-2.52), 2.28 (2.21-2.35), and 1.22 (1.20-1.24), respectively. Respective age-adjusted HRs (95% CIs) were 1.13 (1.12-1.14), 1.36 (1.34-1.37), 1.87 (1.84-1.89), 2.24 (2.18-2.31) and 1.19 (1.17-1.21), and multivariable-adjusted HRs (95% CIs) were 1.11 (1.10-1.12), 1.24 (1.22-1.25), 1.46 (1.43-1.48), 1.42 (1.38-1.47), and 1.13 (1.11-1.16). Similar patterns were observed for associations with hospitalizations. CONCLUSION Data needed to define CKD using KDIGO criteria were available in six out of ten patients, and CKD could be defined in seven out of ten patients with data. HF patients with KDIGO-defined CKD had higher risks for poor outcomes, most of which was not explained by abnormal kidney structure or function. Future studies need to examine whether CKD defined using a single eGFR is characteristically and prognostically different from CKD defined using KDIGO criteria.

Prediction of cardiovascular and renal risk among patients with apparent treatment-resistant hypertension in the United States using machine learning methods. J Clin Hypertens (Greenwich) 2024; 26:500-513. [PMID: 38523465 PMCID: PMC11088433 DOI: 10.1111/jch.14791] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Revised: 02/08/2024] [Accepted: 02/11/2024] [Indexed: 03/26/2024]
Abstract
Apparent treatment-resistant hypertension (aTRH), defined as blood pressure (BP) that remains uncontrolled despite unconfirmed concurrent treatment with three antihypertensives, is associated with an increased risk of developing cardiovascular and renal complications compared with controlled hypertension. We aimed to identify the characteristics of aTRH patients with an elevated risk of major adverse cardiovascular events plus (MACE+; defined as stroke, myocardial infarction, or heart failure hospitalization) and end stage renal disease (ESRD). This retrospective cohort study included aTRH patients (BP ≥140/90 mmHg and taking ≥3 antihypertensives) from the United States-based Optum® de-identified Electronic Health Record dataset and used machine learning models to identify risk factors of MACE+ or ESRD. Patients had claims for ≥3 antihypertensive classes within 30 days between January 1, 2015 and June 30, 2021, and two office BP measures recorded 1-90 days apart within 30 days to 11 months after the index regimen date. Of a total 18 797 070 patients identified with any hypertension, 71 100 patients had aTRH. During the study period (mean 25.5 months), 4944 (7.0%) patients had a MACE+ and 2403 (3.4%) developed ESRD. In total, 22 risk factors were included in the MACE+ model and 16 in the ESRD model, and most were significantly associated with study outcomes. The risk factors with the largest impact on MACE+ risk were congestive heart failure, stages 4 and 5 chronic kidney disease (CKD), age ≥80 years, and living in the Southern region of the United States. The risk factors with the largest impact on ESRD risk, other than pre-existing CKD, were anemia, congestive heart failure, and type 2 diabetes. The overall study cohort had a 5-year predicted MACE+ risk of 13.4%; this risk was increased in those in the top 50% and 25% high-risk groups (21.2% and 29.5%, respectively). The overall study cohort had a predicted 5-year risk of ESRD of 6.8%, which was increased in the top 50% and 25% high-risk groups (10.9% and 17.1%, respectively). We conclude that risk models developed in our study can reliably identify patients with aTRH at risk of MACE+ and ESRD based on information available in electronic health records; such models may be used to identify aTRH patients at high risk of adverse outcomes who may benefit from novel treatment interventions.

Rilparencel (Renal Autologous Cell Therapy-REACT®) for Chronic Kidney Disease and Type 1 and 2 Diabetes: Phase 2 Trial Design Evaluating Bilateral Kidney Dosing and Re-Dosing Triggers. Am J Nephrol 2024:000537942. [PMID: 38423000 DOI: 10.1159/000537942] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Accepted: 02/08/2024] [Indexed: 03/02/2024]
Abstract
INTRODUCTION Autologous cell-based therapies (CBT) to treat Chronic Kidney Disease (CKD) with diabetes are novel and can potentially preserve renal function and decelerate disease progression. CBT dosing schedules are in early development and may benefit from individual bilateral organ dosing and kidney-dependent function to improve efficacy and durability. The objective of this open-label, phase 2 randomized controlled trial (RCT) is to evaluate participants' response to rilparencel (Renal Autologous Cell Therapy-REACT®) following bilateral percutaneous kidney injections into the kidney cortex with a prescribed dosing schedule versus re-dosing based on biomarker triggers. METHODS Eligible participants with type 1 or 2 diabetes and CKD, eGFR 20-50 ml/min/1.73 m2, UACR 30-5000 mg/g, Hemoglobin > 10 g/dL and glycated hemoglobin A1c < 10% were enrolled. After a percutaneous kidney biopsy and bioprocessing ex vivo expansion of Selected Renal Cells, participants were randomized 1:1 into two cohorts determined by the dosing scheme. Cohort 1 receives two cell injections, one in each kidney three months apart, and Cohort 2 receives one injection and the second dose only if there is a sustained eGFR decline of ≥20 ml/min/1.73 m2 and/or UACR increase of ≥ 30% confirmed by re-testing. CONCLUSION This multicenter phase 2 RCT is designed to investigate the efficacy and safety of rilparencel with bilateral kidney dosing and comparing two injection schedules with the potential of preserving or improving kidney function and delaying kidney disease progression among patients with Stages 3a-4 CKD with diabetes.

Estimated Lifetime Cardiovascular, Kidney, and Mortality Benefits of Combination Treatment With SGLT2 Inhibitors, GLP-1 Receptor Agonists, and Nonsteroidal MRA Compared With Conventional Care in Patients With Type 2 Diabetes and Albuminuria. Circulation 2024; 149:450-462. [PMID: 37952217 DOI: 10.1161/circulationaha.123.067584] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/12/2023] [Accepted: 11/07/2023] [Indexed: 11/14/2023]
Abstract
BACKGROUND Sodium glucose cotransporter 2 inhibitors (SGLT2i), glucagon-like peptide-1 receptor agonists (GLP-1 RA), and the nonsteroidal mineralocorticoid receptor antagonist (ns-MRA) finerenone all individually reduce cardiovascular, kidney, and mortality outcomes in patients with type 2 diabetes and albuminuria. However, the lifetime benefits of combination therapy with these medicines are not known. METHODS We used data from 2 SGLT2i trials (CANVAS [Canagliflozin Cardiovascular Assessment] and CREDENCE [Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation]), 2 ns-MRA trials (FIDELIO-DKD [Finerenone in Reducing Kidney Failure and Disease Progression in Diabetic Kidney Disease] and FIGARO-DKD [Efficacy and Safety of Finerenone in Subjects With Type 2 Diabetes Mellitus and the Clinical Diagnosis of Diabetic Kidney Disease]), and 8 GLP-1 RA trials to estimate the relative effects of combination therapy versus conventional care (renin-angiotensin system blockade and traditional risk factor control) on cardiovascular, kidney, and mortality outcomes. Using actuarial methods, we then estimated absolute risk reductions with combination SGLT2i, GLP-1 RA, and ns-MRA in patients with type 2 diabetes and at least moderately increased albuminuria (urinary albumin:creatinine ratio ≥30 mg/g) by applying estimated combination treatment effects to participants receiving conventional care in CANVAS and CREDENCE. RESULTS Compared with conventional care, the combination of SGLT2i, GLP-1 RA, and ns-MRA was associated with a hazard ratio of 0.65 (95% CI, 0.55-0.76) for major adverse cardiovascular events (nonfatal myocardial infarction, nonfatal stroke, or cardiovascular death). The corresponding estimated absolute risk reduction over 3 years was 4.4% (95% CI, 3.0-5.7), with a number needed to treat of 23 (95% CI, 18-33). For a 50-year-old patient commencing combination therapy, estimated major adverse cardiovascular event-free survival was 21.1 years compared with 17.9 years for conventional care (3.2 years gained [95% CI, 2.1-4.3]). There were also projected gains in survival free from hospitalized heart failure (3.2 years [95% CI, 2.4-4.0]), chronic kidney disease progression (5.5 years [95% CI, 4.0-6.7]), cardiovascular death (2.2 years [95% CI, 1.2-3.0]), and all-cause death (2.4 years [95% CI, 1.4-3.4]). Attenuated but clinically relevant gains in event-free survival were observed in analyses assuming 50% additive effects of combination therapy, including for major adverse cardiovascular events (2.4 years [95% CI, 1.1-3.5]), chronic kidney disease progression (4.5 years [95% CI, 2.8-5.9]), and all-cause death (1.8 years [95% CI, 0.7-2.8]). CONCLUSIONS In patients with type 2 diabetes and at least moderately increased albuminuria, combination treatment of SGLT2i, GLP-1 RA, and ns-MRA has the potential to afford relevant gains in cardiovascular and kidney event-free and overall survival.

Abstract
More than one-third of people with diabetes develop diabetic kidney disease (DKD), which substantially increases risks of kidney failure, cardiovascular disease (CVD), hypoglycemia, death, and other adverse health outcomes. A multifaceted approach incorporating self-management education, lifestyle optimization, pharmacological intervention, CVD prevention, and psychosocial support is crucial to mitigate the onset and progression of DKD. The American Diabetes Association convened an expert panel to develop the DKD Prevention Model presented herein. This model addresses prevention and treatment, including screening guidelines, diagnostic tools, and management approaches; comprehensive, holistic interventions; well-defined roles for interdisciplinary health care professionals; community engagement; and future directions for research and policy.

Development and Validation of a New Hierarchical Composite End Point for Clinical Trials of Kidney Disease Progression. J Am Soc Nephrol 2023; 34:2025-2038. [PMID: 37872654 PMCID: PMC10703083 DOI: 10.1681/asn.0000000000000243] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Accepted: 09/20/2023] [Indexed: 10/25/2023] Open
Abstract
SIGNIFICANCE STATEMENT The established composite kidney end point in clinical trials combines clinical events with sustained large changes in GFR but does not weigh the relative clinical importance of the end point components. By contrast, a hierarchical composite end point (HCE) accounts for the clinical importance of the end point components. The authors developed and validated a kidney HCE that combines clinical kidney outcomes with longitudinal GFR changes (GFR slope). They demonstrate that in seven major placebo-controlled kidney outcome trials with different medications, treatment effect estimates on the HCE were consistently in similar directions and of similar magnitudes compared with treatment effects on the established kidney end point. The HCE's prioritization of clinical outcomes and ability to combine dichotomous outcomes with GFR slope make it an attractive alternative to the established kidney end point. BACKGROUND The established composite kidney end point in clinical trials combines clinical events with sustained large changes in GFR. However, the statistical method does not weigh the relative clinical importance of the end point components. A HCE accounts for the clinical importance of the end point components and enables combining dichotomous outcomes with continuous measures. METHODS We developed and validated a new HCE for kidney disease progression, performing post hoc analyses of seven major Phase 3 placebo-controlled trials that assessed the effects of canagliflozin, dapagliflozin, finerenone, atrasentan, losartan, irbesartan, and aliskiren in patients with CKD. We calculated the win odds (WOs) for treatment effects on a kidney HCE, defined as a hierarchical composite of all-cause mortality; kidney failure; sustained 57%, 50%, and 40% GFR declines from baseline; and GFR slope. The WO describes the odds of a more favorable outcome for receiving the active compared with the control. We compared the WO with the hazard ratio (HR) of the primary kidney outcome of the original trials. RESULTS In all trials, treatment effects calculated with the WO reflected a similar direction and magnitude of the treatment effect compared with the HR. Clinical trials incorporating the HCE would achieve increased statistical power compared with the established composite end point at equivalent sample sizes. CONCLUSIONS In seven major kidney clinical trials, the WO and HR provided similar direction of treatment effect estimates with smaller HRs associated with larger WOs. The prioritization of clinical outcomes and inclusion of broader composite end points makes the HCE an attractive alternative to the established kidney end point.

Managing Phosphate Burden in Patients Receiving Dialysis: Beyond Phosphate Binders and Diet. KIDNEY360 2023; 4:1650-1656. [PMID: 37870525 PMCID: PMC10695651 DOI: 10.34067/kid.0000000000000262] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Accepted: 09/07/2023] [Indexed: 10/24/2023]
Abstract
Most patients receiving dialysis rely on dietary restriction and phosphate binders to minimize the risk of hyperphosphatemia, which is associated with increased mortality. However, dietary restriction is difficult because of hidden phosphate additives in processed foods and medications. Restriction of dietary phosphate sources such as protein may increase the risk of malnutrition. Phosphate binders, the only pharmacologic option for phosphate management since aluminum salts were introduced several decades ago, are often insufficient for binding the 1400-2500 mg of phosphate potentially consumed daily. Over the last decade, serum phosphate levels in the United States have risen, and >69% of patients receiving dialysis exhibited a most recent phosphate level >4.5 mg/dl (above the normal range), indicating an urgent need for new, more effective therapies to manage phosphate burden. Novel, nonbinder therapies such as transcellular and paracellular phosphate absorption inhibitors may be used for phosphate management, and future studies should examine whether they allow fewer dietary restrictions for patients receiving dialysis, potentially improving patient quality of life and nutritional status. It is imperative that we collaborate to move beyond the restrictive approaches available today and provide patients and clinicians with an array of strategies so that they may choose the most appropriate patient-centered therapy.

Estimated lifetime benefit of novel pharmacological therapies in patients with type 2 diabetes and chronic kidney disease: A joint analysis of randomized controlled clinical trials. Diabetes Obes Metab 2023; 25:3327-3336. [PMID: 37580309 DOI: 10.1111/dom.15232] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/11/2023] [Revised: 07/07/2023] [Accepted: 07/19/2023] [Indexed: 08/16/2023]
Abstract
AIM To estimate the lifetime benefit of a combination treatment of sodium-glucose co-transporter 2 (SGLT2) inhibitors and mineralocorticoid-receptor antagonists (MRA) in patients with type 2 diabetes and chronic kidney disease (CKD). MATERIALS AND METHODS The cumulative effect of combination treatment was derived from trial-level estimates of the effect of an SGLT2 inhibitor (canagliflozin) and MRA (finerenone) from the CREDENCE (N = 4401) and FIDELIO (N = 5734) trials, respectively. The cumulative effect was applied to the control group of patients with type 2 diabetes in the DAPA-CKD trial (N = 1451) to estimate long-term gains in event-free and overall survival. The analysis was repeated in an observational study. The primary outcome was a composite endpoint of doubling of serum creatinine, end-stage kidney disease or death because of kidney failure. RESULTS The hazard ratio of combination treatment for the primary outcome was 0.50 [95% confidence interval (CI): 0.44, 0.57]. At age 50 years, the estimated event-free survival from the primary outcome was 16.7 years (95% CI: 18.1, 21.0) with combination treatment versus 10.0 years (95% CI: 6.8, 12.3) with angiotensin-converting enzyme inhibitors/angiotensin receptor blockers resulting in an incremental gain of 6.7 years (95% CI: 5.5, 7.9). In an observational study, the estimated gain in event-free survival regarding primary outcome was 6.3 years (95% CI: 5.2, 7.3). In a conservative scenario, assuming low adherence (70% of the observed adherence) and less pronounced efficacy (70% of the observed efficacy with 2% yearly decline) of combination therapy, gain in event-free survival regarding primary outcome was 2.5 years (95% CI: 2.0, 2.9). CONCLUSIONS Combined disease-modifying treatment with an SGLT2 inhibitor and MRA in patients with type 2 diabetes and CKD may substantially increase the number of years free from kidney failure and mortality.

Abstract
BACKGROUND Chronic kidney disease (CKD) is a common complication of type 2 diabetes (T2D). Glucagon-like peptide-1 receptor agonists (GLP-1RAs) improve glycaemic control and lower body weight in people with T2D, and some reduce the risk of cardiovascular (CV) events in those with high CV risk. GLP-1RAs might also have kidney-protective effects. We report the design and baseline data for FLOW (NCT03819153), a trial investigating the effects of semaglutide, a once-weekly (OW) GLP-1RA, on kidney outcomes in participants with CKD and T2D. METHODS FLOW is a randomised, double-blind, parallel-group, multinational, phase 3b trial. Participants with T2D, estimated glomerular filtration rate (eGFR) ≥50‒≤75 ml/min/1.73 m2 and urine albumin:creatinine ratio (UACR) >300‒<5000 mg/g or eGFR ≥25‒<50 ml/min/1.73 m2 and UACR >100‒<5000 mg/g were randomised 1:1 to OW semaglutide 1.0 mg or matched placebo, with renin-angiotensin-aldosterone system blockade (unless not tolerated/contraindicated). The composite primary endpoint is time to first kidney failure (persistent eGFR <15 ml/min/1.73 m2 or initiation of chronic kidney replacement therapy), persistent ≥50% reduction in eGFR or death from kidney or CV causes. RESULTS Enrolled participants (N = 3534) had a baseline mean age of 66.6 years [standard deviation (SD) 9.0], haemoglobin A1c of 7.8% (SD 1.3), diabetes duration of 17.4 years (SD 9.3), eGFR of 47.0 ml/min/1.73 m2 (SD 15.2) and median UACR of 568 mg/g (range 2‒11 852). According to Kidney Disease: Improving Global Outcomes guidelines categorisation, 68.2% were at very high risk for CKD progression. CONCLUSION FLOW will evaluate the effect of semaglutide on kidney outcomes in participants with CKD and T2D, and is expected to be completed in late 2024.

Association of uncontrolled blood pressure in apparent treatment-resistant hypertension with increased risk of major adverse cardiovascular events plus. J Clin Hypertens (Greenwich) 2023; 25:737-747. [PMID: 37461262 PMCID: PMC10423765 DOI: 10.1111/jch.14701] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2023] [Revised: 06/30/2023] [Accepted: 07/04/2023] [Indexed: 08/15/2023]
Abstract
Patients with apparent treatment-resistant hypertension (aTRH) are at increased risk of end-organ damage and cardiovascular events. Little is known about the effects of blood pressure (BP) control in this population. Using a national claims database integrated with electronic medical records, the authors evaluated the relationships between uncontrolled BP (UBP; ≥130/80 mmHg) or controlled BP (CBP; <130/80 mmHg) and risk of major adverse cardiovascular events plus (MACE+; stroke, myocardial infarction, heart failure requiring hospitalization) and end-stage renal disease (ESRD) in adult patients with aTRH (taking ≥3 antihypertensive medication classes concurrently within 30 days between January 1, 2015 and June 30, 2021). MACE+ components were also evaluated separately. Multivariable regression models were used to adjust for baseline differences in demographic and clinical characteristics, and sensitivity analyses using CBP <140/90 mmHg were conducted. Patients with UBP (n = 22 333) were younger and had fewer comorbidities at baseline than those with CBP (n = 11 427). In the primary analysis, which adjusted for these baseline differences, UBP versus CBP patients were at an 8% increased risk of MACE+ (driven by a 31% increased risk of stroke) and a 53% increased risk of ESRD after 2.7 years of follow-up. Greater MACE+ (22%) and ESRD (98%) risk increases with UBP versus CBP were seen in the sensitivity analysis. These real-world data showed an association between suboptimal BP control in patients with aTRH and higher incidence of MACE+ and ESRD linked with UBP despite the use of multidrug regimens. Thus, there remains a need for improved aTRH management.

Kidney and Cardiovascular Effects of Canagliflozin According to Age and Sex: A Post Hoc Analysis of the CREDENCE Randomized Clinical Trial. Am J Kidney Dis 2023; 82:84-96.e1. [PMID: 36889425 DOI: 10.1053/j.ajkd.2022.12.015] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Accepted: 12/21/2022] [Indexed: 03/08/2023]
Abstract
RATIONALE & OBJECTIVE It is unclear whether the effect of canagliflozin on adverse kidney and cardiovascular events in those with diabetic kidney disease varies by age and sex. We assessed the effects of canagliflozin among age group categories and between sexes in the Canagliflozin and Renal Endpoints in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) study. STUDY DESIGN Secondary analysis of a randomized controlled trial. SETTING & PARTICIPANTS Participants in the CREDENCE trial. INTERVENTION Participants were randomly assigned to receive canagliflozin 100mg/d or placebo. OUTCOMES Primary composite outcome of kidney failure, doubling of serum creatinine concentration, or death due to kidney or cardiovascular disease. Prespecified secondary and safety outcomes were also analyzed. Outcomes were evaluated by age at baseline (<60, 60-69, and≥70 years) and sex in the intention-to-treat population using Cox regression models. RESULTS The mean age of the cohort was 63.0±9.2 years, and 34% were female. Older age and female sex were independently associated with a lower risk of the composite of adverse kidney outcomes. There was no evidence that the effect of canagliflozin on the primary outcome (a composite of kidney failure, a doubling of serum creatinine concentration, or death from kidney or cardiovascular causes) differed between age groups (HRs, 0.67 [95% CI, 0.52-0.87], 0.63 [0.48-0.82], and 0.89 [0.61-1.29] for ages<60, 60-69, and≥70 years, respectively; P=0.3for interaction) or sexes (HRs, 0.71 [95% CI, 0.54-0.95] and 0.69 [0.56-0.84] in women and men, respectively; P=0.8for interaction). No differences in safety outcomes by age group or sex were observed. LIMITATIONS This was a post hoc analysis with multiple comparisons. CONCLUSIONS Canagliflozin consistently reduced the relative risk of kidney events in people with diabetic kidney disease in both sexes and across age subgroups. As a result of greater background risk, the absolute reduction in adverse kidney outcomes was greater in younger participants. FUNDING This post hoc analysis of the CREDENCE trial was not funded. The CREDENCE study was sponsored by Janssen Research and Development and was conducted collaboratively by the sponsor, an academic-led steering committee, and an academic research organization, George Clinical. TRIAL REGISTRATION The original CREDENCE trial was registered at ClinicalTrials.gov with study number NCT02065791.

Effects of newer kidney protective agents on kidney endpoints provide implications for future clinical trials. Kidney Int 2023; 104:181-188. [PMID: 37119876 DOI: 10.1016/j.kint.2023.03.037] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2023] [Revised: 03/02/2023] [Accepted: 03/24/2023] [Indexed: 05/01/2023]
Abstract
Doubling of serum creatinine (equivalent to a 57% decline in the estimated glomerular filtration rate (eGFR)) is an accepted component of a composite kidney endpoint in clinical trials. Smaller declines in eGFR (40%, 50%) have been applied in several recently conducted clinical trials. Here, we assessed the effects of newer kidney protective agents on endpoints including smaller proportional declines in eGFR to compare relative event rates and the magnitude of observed treatment effects. We performed a post hoc analysis of 4401 patients in the CREDENCE, 4304 in the DAPA-CKD, 5734 in the FIDELIO-DKD, and 3668 in the SONAR trials, which assessed the effects of canagliflozin, dapagliflozin, finerenone and atrasentan in patients with chronic kidney disease. Effects of active therapies versus placebo on alternative composite kidney endpoints incorporating different eGFR decline thresholds (40%, 50%, or 57% eGFR reductions from baseline) with kidney failure or death due to kidney failure were compared. Cox-proportional hazards regression models were used to assess and compare treatment effects. During follow-up, event rates were higher for endpoints incorporating smaller versus larger eGFR decline thresholds. Compared to the treatment effects on kidney failure or death due to kidney failure, the magnitude of relative treatment effects was generally similar when considering composite endpoints incorporating smaller declines in eGFR. Hazard ratios for the four interventions ranged from 0.63 to 0.82 for the endpoint incorporating 40% eGFR decline and 0.59 to 0.76 for the endpoint incorporating 57% eGFR decline. Clinical trials incorporating a 40% eGFR decline in a composite endpoint would require approximately half the number of participants compared to a 57% eGFR decline with equivalent statistical power. Thus, in populations at high risk of CKD progression, the relative effects of newer kidney protective therapies appear generally similar across endpoints based on varying eGFR decline thresholds.

Canagliflozin, Blood Pressure Variability, and Risk of Cardiovascular, Kidney, and Mortality Outcomes: Pooled Individual Participant Data From the CANVAS and CREDENCE Trials.

Abstract
Background Sodium glucose cotransporter-2 inhibitors reduce systolic blood pressure (SBP), but whether they affect SBP variability is unknown. There also remains uncertainty regarding the prognostic value of SBP variability for different clinical outcomes. Methods and Results Using individual participant data from the CANVAS (Canagliflozin Cardiovascular Assessment Study) Program and CREDENCE (Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation) trial, we assessed the effect of canagliflozin on SBP variability in people with type 2 diabetes across 4 study visits over 1.5 years as measured by standard deviation, coefficient of variation, and variability independent of the mean. We used multivariable Cox regression models to estimate associations of SBP variability with cardiovascular, kidney, and mortality outcomes. In 11 551 trial participants, canagliflozin modestly lowered the standard deviation of SBP variability (-0.25 mm Hg [95% CI, -0.44 to -0.06]), but there was no effect on coefficient of variation (0.02% [95% CI, -0.12 to 0.16]) or variability independent of the mean (0.08 U [95% CI, -0.11 to 0.26]) when adjusting for correlation with mean SBP. Each 1 standard deviation increase in standard deviation of SBP variability was independently associated with higher risk of hospitalization for heart failure (hazard ratio [HR], 1.19 [95% CI, 1.02-1.38]) and all-cause mortality (HR, 1.12 [95% CI, 1.01-1.25]), with consistent results observed for coefficient of variation and variability independent of the mean. Increases in SBP variability were not associated with kidney outcomes. Conclusions In people with type 2 diabetes at high cardiovascular risk or with chronic kidney disease, higher visit-to-visit SBP variability is independently associated with risks of hospitalization for heart failure and all-cause mortality. Canagliflozin has little to no effect on SBP variability, independent of its established SBP-lowering effect.

The sodium-glucose cotransporter-2 inhibitor canagliflozin does not increase risk of non-genital skin and soft tissue infections in people with type 2 diabetes mellitus: A pooled post hoc analysis from the CANVAS Program and CREDENCE randomized double-blind trials. Diabetes Obes Metab 2023. [PMID: 37161691 DOI: 10.1111/dom.15091] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2022] [Revised: 04/01/2023] [Accepted: 04/09/2023] [Indexed: 05/11/2023]
Abstract
AIMS To assess whether the sodium-glucose cotransporter-2 (SGLT2) inhibitor canagliflozin affects risk of non-genital skin and soft tissue infections (SSTIs). MATERIALS AND METHODS We performed a post hoc pooled individual participant analysis of the CANVAS Program and CREDENCE trials that randomized people with type 2 diabetes at high cardiovascular risk and/or with chronic kidney disease to either canagliflozin or placebo. Investigator-reported adverse events were assessed by two blinded authors following predetermined criteria for non-genital SSTIs. Risks of non-genital SSTIs, overall and within prespecified subgroups, and risk of non-genital fungal SSTIs, were analysed using Cox regression models. Factors associated with non-genital SSTIs were assessed using multivariable Cox regression models. RESULTS Overall, 903 of 14 531 participants (6%) experienced non-genital SSTIs over a median follow-up of 26 months. No difference was observed in non-genital SSTI rates between canagliflozin and placebo (24.0 events/1000 person-years vs. 23.9 events/1000 person-years, respectively; hazard ratio [HR] 0.97, 95% confidence interval [CI] 0.85-1.11; P = 0.70), with consistent results across subgroups (all P interaction > 0.05). The risk of recurrent events and non-genital fungal infection also did not differ significantly between canagliflozin and placebo (HR 1.06, 95% CI 0.94-1.19 [P = 0.32] and HR 1.18, 95% CI 0.88-1.60 [P = 0.27], respectively). Baseline factors independently associated with non-genital SSTIs were younger age, male sex, higher body mass index, higher glycated haemoglobin, lower estimated glomerular filtration rate (eGFR), established peripheral vascular disease, and history of neuropathy. CONCLUSIONS Canagliflozin did not affect risk of non-genital SSTIs or non-genital fungal SSTIs compared with placebo. These findings suggest that any SGLT2 inhibitor-mediated change in skin microenvironment is unlikely to have meaningful clinical consequences.

Abstract
Nearly 500 000 individuals are treated with maintenance hemodialysis for kidney failure in the United States, and roughly half will die of cardiovascular causes. Hypertension, an important and modifiable risk factor for cardiovascular disease, is observed in >80% of patients treated with maintenance hemodialysis. The pathophysiology of hypertension in patients treated with maintenance hemodialysis is multifactorial and differs from that seen in other patient populations. Factors that contribute to hypertension in patients treated with hemodialysis include volume overload, arterial stiffness, enhanced activity of the sympathetic nervous and renin-angiotensin-aldosterone systems, endothelial dysfunction, and use of erythropoietin-stimulating agents. This scientific statement reviews the current evidence on defining, diagnosing, and treating hypertension in patients treated with maintenance hemodialysis and highlights opportunities for future investigation, including studies on blood pressure targets and treatment strategies.

Abstract
Nonsteroidal mineralocorticoid receptor antagonists (MRAs) are a new class of drugs developed to address the medical need for effective and safer treatment to protect the kidney and the heart in patients with diabetic kidney disease (DKD). There are several drugs within this class at varying stages of clinical development. Finerenone is the first nonsteroidal MRA approved in the US for treating patients with chronic kidney disease (CKD) associated with type 2 diabetes (T2D). In clinical studies, finerenone slowed CKD progression without inducing marked antihypertensive effects. Esaxerenone is a nonsteroidal MRA with proven blood pressure-lowering efficacy that is currently licensed in Japan for treating hypertension. There are also three other nonsteroidal MRAs in mid-to-late stages of clinical development. Here we overview evidence addressing pharmacological and clinical differences between the nonsteroidal MRAs and the steroidal MRAs spironolactone and eplerenone. First, we describe a framework that highlights the role of aldosterone-mediated pathological overactivation of the mineralocorticoid receptor and inflammation as important drivers of CKD progression. Second, we discuss the benefits and adverse events profile of steroidal MRAs, the latter of which are often a limiting factor to their use in routine clinical practice. Finally, we show that nonsteroidal MRAs differ from steroidal MRAs based on pharmacology and clinical effects, giving the potential to expand the therapeutic options for patients with DKD. In the recently completed DKD outcome program comprising two randomized clinical trials - FIDELIO-DKD and FIGARO-DKD - and the FIDELITY analysis of both trials evaluating more than 13,000 patients, the nonsteroidal MRA finerenone demonstrated beneficial effects on the kidney and the heart across a broad spectrum of patients with CKD and T2D. The long-term efficacy of finerenone on cardiac and renal morbidity and mortality endpoints, along with the anti-hypertensive efficacy of esaxerenone, widens the scope of available therapies for patients with DKD.

Abstract
Background Patients with stage 4 chronic kidney disease (CKD) and type 2 diabetes have limited treatment options to reduce their persistent cardiovascular and kidney risk. In FIDELITY, a prespecified pooled analysis of FIDELIO-DKD and FIGARO-DKD, finerenone improved heart-kidney outcomes in participants with CKD and type 2 diabetes. Methods This FIDELITY subgroup analysis investigated the effects of finerenone in participants with stage 4 CKD (estimated glomerular filtration rate [eGFR] <30 ml/min/1.73 m2). Efficacy outcomes included a cardiovascular composite (cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure) and a kidney composite (kidney failure, sustained ≥57% decrease in eGFR from baseline, or kidney disease death). Results Of 13,023 participants, 890 (7%) had stage 4 CKD. The hazard ratio for risk of cardiovascular composite outcome with finerenone versus placebo was 0.78 (95% confidence interval 0.57-1.07). The kidney composite outcome proportional hazards assumption was not met for the overall study period, with a protective effect only shown up to 2 years, after which the direction of association was inconsistent and an observed loss of precision over time incurred on finerenone versus placebo risk differences. Nonetheless, albuminuria and rate of eGFR decline were consistently reduced with finerenone versus placebo. Adverse events were balanced between treatment arms. Hyperkalemia was the most common AE reported (stage 4 CKD: 26% and 13% for finerenone versus placebo, respectively) however, the incidence of hyperkalemia leading to permanent discontinuation was low (stage 4 CKD: 3% and 2% for finerenone versus placebo, respectively). Conclusions The cardiovascular benefits and safety profile of finerenone in participants with stage 4 CKD were consistent with the overall FIDELITY population; this was also the case for albuminuria and the rate of eGFR decline. The effects on the composite kidney outcome were not consistent over time.

Abstract
AIMS Finerenone reduces the risk of cardiovascular events in patients with chronic kidney disease (CKD) and type 2 diabetes (T2D). We investigated the causes of mortality in the FIDELITY population. METHODS AND RESULTS The FIDELITY prespecified pooled data analysis from FIDELIO-DKD and FIGARO-DKD excluded patients with heart failure and reduced ejection fraction. Outcomes included intention-to-treat and prespecified on-treatment analyses of the risk of all-cause and cardiovascular mortality. Of 13 026 patients [mean age, 64.8 years; mean estimated glomerular filtration rate (eGFR), 57.6 mL/min/1.73 m2], 99.8% were on renin-angiotensin system inhibitors. Finerenone reduced the incidence of all-cause and cardiovascular mortality vs. placebo (8.5% vs. 9.4% and 4.9% vs. 5.6%, respectively) and demonstrated significant on-treatment reductions [hazard ratio (HR), 0.82; 95% confidence interval (CI), 0.70-0.96; P = 0.014 and HR, 0.82; 95% CI, 0.67-0.99; P = 0.040, respectively]. Cardiovascular-related mortality was most common, and finerenone lowered the incidence of sudden cardiac death vs. placebo [1.3% (incidence rate 0.44/100 patient-years) vs. 1.8% (0.58/100 patient-years), respectively; HR, 0.75; 95% CI, 0.57-0.996; P = 0.046]. The effects of finerenone on mortality were similar across all Kidney Disease: Improving Global Outcomes risk groups. Event probability with finerenone at 4 years was consistent irrespective of baseline urine albumin-to-creatinine ratio, but seemingly more pronounced in patients with higher baseline eGFR. CONCLUSION In FIDELITY, finerenone significantly reduced the risk of all-cause and cardiovascular mortality vs. placebo in patients with T2D across a broad spectrum of CKD stages while on treatment, as well as sudden cardiac death in the intention-to-treat population. CLINICAL TRIALS REGISTRATION FIDELIO-DKD and FIGARO-DKD are registered with ClinicalTrials.gov, numbers NCT02540993 and NCT02545049, respectively (funded by Bayer AG).

Abstract
People with diabetes and chronic kidney disease (CKD) are at high risk for kidney failure, atherosclerotic cardiovascular disease, heart failure, and premature mortality. Recent clinical trials support new approaches to treat diabetes and CKD. The 2022 American Diabetes Association (ADA) Standards of Medical Care in Diabetes and the Kidney Disease: Improving Global Outcomes (KDIGO) 2022 Clinical Practice Guideline for Diabetes Management in Chronic Kidney Disease each provide evidence-based recommendations for management. A joint group of ADA and KDIGO representatives reviewed and developed a series of consensus statements to guide clinical care from the ADA and KDIGO guidelines. The published guidelines are aligned in the areas of CKD screening and diagnosis, glycemia monitoring, lifestyle therapies, treatment goals, and pharmacologic management. Recommendations include comprehensive care in which pharmacotherapy that is proven to improve kidney and cardiovascular outcomes is layered on a foundation of healthy lifestyle. Consensus statements provide specific guidance on use of renin-angiotensin system inhibitors, metformin, sodium-glucose cotransporter 2 inhibitors, glucagon-like peptide 1 receptor agonists, and a nonsteroidal mineralocorticoid receptor antagonist. These areas of consensus provide clear direction for implementation of care to improve clinical outcomes of people with diabetes and CKD.

Consensus statements provide specific guidance on use of renin-angiotensin system inhibitors, metformin, sodium-glucose cotransporter-2 inhibitors, glucagon-like peptide 1 receptor agonists, and a nonsteroidal mineralocorticoid receptor antagonist. These areas of consensus provide clear direction for implementation of care to improve clinical outcomes of people with diabetes and CKD.

Abstract
Abstract
Background
Patients with chronic kidney disease and type 2 diabetes (T2D) have a high risk of progression to kidney failure as well as cardiovascular (CV) events. It is established that glucagon-like peptide-1 receptor agonists (GLP-1RAs) improve glycaemic control and reduce body weight. Some CV outcomes trials have shown that GLP-1RAs reduce CV risk in people with T2D at high CV risk; for example, the SUSTAIN 6 trial demonstrated that the GLP-1RA semaglutide significantly lowered the rate of major CV events (CV death, non-fatal myocardial infarction and non-fatal stroke) versus placebo. Some trials have also indicated that GLP-1RAs reduce albuminuria and estimated glomerular filtration rate (eGFR) decline. Based on these previous results indicating potential kidney-protective effects, the FLOW trial (NCT03819153) is evaluating once-weekly, subcutaneous semaglutide 1.0 mg versus placebo on kidney- and CV-related outcomes in participants with T2D. We describe the baseline characteristics and the calculated CV risk of this patient population using the atherosclerotic CV disease (ASCVD) and second manifestations of arterial disease (SMART) risk calculators.
Methods
FLOW is an ongoing, multicentre, randomised, double-blind, parallel-group, event-driven, phase 3b trial, with participants randomised 1:1 to semaglutide or placebo, each in addition to standard of care. Recruitment is complete and 3,535 participants with T2D, an eGFR ≥25–≤75 mL/min/1.73 m2, and urine albumin-to-creatinine ratio ≥100–≤5,000 mg/g have been enrolled. The primary endpoint is time to first occurrence of a kidney composite that includes ≥50% persistent eGFR reduction, kidney failure (persistent eGFR <15 mL/min/1.73 m2 or initiation of chronic dialysis or kidney transplantation), and kidney-related death, or CV death. Key secondary outcomes include time to first occurrence of CV death, myocardial infarction or stroke.
Results
The baseline clinical characteristics and demographics are shown (Table 1). Median age was 68 years, 30% were female, mean diabetes duration was 17 years, and 98% had a history of hypertension. Overall, 52% of participants had a previous CV event. The calculated 10-year risk for ASCVD events in those without prior ASCVD was 31% in males and 18% in females, and in those with previous CV events was 37–56% in males and 35–53% in females depending on the type of CV disease reported in the calculator (Table 2).
Conclusions
The FLOW trial has completed enrolment. Based on the ASCVD and SMART risk calculators, the enrolled population has a substantial risk for adverse CV outcomes. Event ascertainment is ongoing, and the FLOW trial will provide evidence for the potential of semaglutide to improve kidney and CV outcomes in the T2D population.

Abstract
Abstract
Background/Introduction
Chronic kidney disease (CKD) in patients with type 2 diabetes (T2D) is associated with an increased risk of cardiovascular (CV) events. The modifiability of CKD-associated CV risk in patients with T2D across a spectrum of CKD stages remains unknown.
Purpose
To test whether CKD, as defined jointly by estimated glomerular filtration rate (eGFR) and albuminuria (urine albumin-to-creatinine ratio [UACR]), is a modifiable CV risk factor in patients with T2D. Furthermore, to estimate the population-wide reduction in first CV events in the US if all eligible patients were treated with finerenone.
Methods
We estimated the incidence rates of CV events (composite of CV death, non-fatal stroke, non-fatal myocardial infarction, or hospitalisation for heart failure) over a median follow-up of 3.0 years in 13,026 patients with CKD and T2D, treated with finerenone or placebo, in a joint analysis by eGFR and UACR categories. Patients were from FIDELITY, a prespecified pooled analysis of two phase III trials, and had an eGFR ≥25 ml/min/1.73 m2 and UACR 30–5000 mg/g at screening.The potential impact of finerenone treatment on the US population was evaluated by simulating the number of first CV events that could be prevented per year with finerenone, using incidence rates from FIDELITY and prevalence rates of CKD in patients with T2D from the National Health and Nutrition Examination Survey (NHANES).
Results
Lower eGFR and higher UACR categories were associated with higher incidences of CV events in finerenone and placebo recipients (Figure). Finerenone reduced CV risk versus placebo (hazard ratio 0.86; 95% CI 0.78–0.95; p=0.0018) without evidence of moderation of risk reduction by combined eGFR and UACR categories (p interaction = 0.66; Figure 1). Using NHANES, a total of 6.4 million treatment-eligible individuals with CKD and T2D were identified; 75% had CKD with an eGFR ≥60 ml/min/1.73 m2 and 25% had CKD with an eGFR <60 ml/min/1.73 m2. Simulations using this NHANES population projected that 1 year of finerenone treatment could prevent 38,359 CV events in US patients with CKD and T2D, with 66% of events prevented in patients with eGFR ≥60 ml/min/1.73 m2.
Conclusions
Higher albuminuria and lower eGFR are associated with increased CV risk in patients with T2D. Across a range of eGFR and albuminuria categories, CV risk is modifiable. Therefore, CKD is a modifiable CV risk factor in part mediated by mineralocorticoid receptor overactivation. UACR screening to identify patients with T2D and albuminuria with an eGFR ≥60 ml/min/1.73 m2 is likely to provide a significant opportunity for population benefits.

Abstract
Background The sodium‐glucose cotransporter 2 inhibitor canagliflozin reduced the risk of first cardiovascular composite events in the CREDENCE (Canagliflozin and Renal Events in Diabetes With Established Nephropathy Clinical Evaluation) trial. In this post hoc analysis, we evaluated the effect of canagliflozin on total (first and recurrent) cardiovascular events. Methods and Results The CREDENCE trial compared canagliflozin or matching placebo in 4401 patients with type 2 diabetes, albuminuria, and estimated glomerular filtration rate of 30 to <90 mL/min per 1.73 m2, over a median of 2.6 years. The primary outcome was analyzed as a composite of any cardiovascular event including myocardial infarction, stroke, hospitalization for heart failure, hospitalization for unstable angina, and cardiovascular death. Negative binomial regression models were used to assess the effect of canagliflozin on the net burden of cardiovascular events. During the trial, 634 patients had 883 cardiovascular events, of whom 472 (74%) had just 1 cardiovascular event and 162 (26%) had multiple cardiovascular events. Canagliflozin reduced first cardiovascular events by 26% (hazard ratio, 0.74 [95% CI, 0.63–0.86]; P<0.001) and total cardiovascular events by 29% (incidence rate ratio, 0.71 [95% CI, 0.59–0.86]; P<0.001). The absolute risk difference per 1000 patients treated over 2.5 years was −44 (95% CI, −67 to −21) first cardiovascular events and −73 (95% CI, −114 to −33) total events. Conclusions Canagliflozin reduced cardiovascular events, with a larger absolute benefit for total cardiovascular than first cardiovascular events. These findings provide further support for the benefit of continuing canagliflozin therapy after an initial event to prevent recurrent cardiovascular events.

Abstract
OBJECTIVES Recent trials of glucose-lowering drugs (GLDs) have drawn attention to renal outcomes. Our goal was to understand how patients with diabetic kidney disease (DKD) are treated in general practices in the United States. STUDY DESIGN Retrospective cohort study using a national-level claims data set and electronic health records. METHODS Patients (≥ 18 years) with type 2 diabetes, whose estimated glomerular filtration rates (eGFRs) were between 15 and 89 mL/min/1.73 m2 between 2016 and 2018, were selected. Use of different GLDs during a 12-month period was examined across all eGFR levels. RESULTS Of the 25,486 sample patients, 69.2%, 18.9%, 9.6%, and 2.3% had an eGFR in the ranges of 60 to 89, 45 to 59, 30 to 44, and 15 to 29 mL/min/1.73 m2, respectively. Metformin was used by nearly 33% of patients with an eGFR of 30 to 44 mL/min/1.73 m2 and by 10% of patients with an eGFR less than 30 mL/min/1.73 m2. Less than 10% (across all eGFR levels) of patients used glucagon-like peptide-1 receptor agonists and sodium-glucose cotransporter-2 inhibitors. Use of insulin was more frequent among patients with a lower eGFR (P < .05). The findings were similar in subgroups with different hemoglobin A1c levels (< 7% and ≥ 7%). CONCLUSIONS Real-world treatment of DKD in the United States is suboptimal. Inappropriate use of some GLD classes, especially in advanced DKD stages, was found along with lower than expected use of modern agents that are considered safe and effective to treat glycemic outcomes. Efforts may be needed to improve understanding of safety, glycemic efficacy, and overall clinical value of GLDs across DKD stages.

Abstract
Chronic kidney disease (CKD) remains underrecognized by patients and clinicians in the primary care setting, largely due to its asymptomatic presentation in early stages. Sodium-glucose cotransporter-2 (SGLT-2) inhibitors have demonstrated kidney-protective effects in clinical trials-including in patients with and without type 2 diabetes (T2D)-and there are several proposed mechanisms for these benefits. Dapagliflozin and canagliflozin are SGLT2 inhibitors with indications for CKD, and only dapagliflozin is indicated for CKD in patients without T2D. Clinically relevant adverse events associated with SGLT-2 inhibitors include volume depletion, diabetic ketoacidosis, and genital mycotic infections.

Abstract
BACKGROUND Despite available interventions, people with type 2 diabetes (T2D) remain at risk of chronic kidney disease (CKD). Finerenone, a potent and selective nonsteroidal mineralocorticoid receptor antagonist, and sodium-glucose co-transporter 2 inhibitors (SGLT2is) can reduce both kidney and cardiovascular risks in people with CKD and T2D. Here we outline the design of a study to investigate whether dual therapy with finerenone and a SGLT2i is superior to either agent alone. METHODS CONFIDENCE (NCT05254002) is a randomized, controlled, double-blind, double-dummy, international, multicentre, three-armed, parallel-group, 7.5-8.5-month, Phase 2 study in approximately 807 adults with T2D, stage 2-3 CKD and a urine albumin-to-creatinine ratio (UACR) from ≥ 300-<5000 mg/g. The primary objective is to demonstrate that 6 months' dual therapy comprising finerenone and the SGLT2i empagliflozin is superior for reducing albuminuria versus either agent alone. Interventions will be once-daily finerenone 10 mg or 20 mg (target dose) plus empagliflozin 10 mg, or empagliflozin 10 mg alone, or finerenone 10 mg or 20 mg (target dose) alone. RESULTS The primary outcome is relative change from baseline in UACR among the three groups. Secondary outcomes will further characterize efficacy and safety, including change in eGFR and incident hyperkalaemia. CONCLUSIONS CONFIDENCE is evaluating the safety, tolerability and efficacy of dual use of finerenone and a SGLT2i in adults with CKD and T2D. Should an additive effect be shown, early and efficient intervention with dual finerenone and SGLT2i therapy could slow disease progression and provide long-term benefits for people with CKD and T2D.

Abstract
Abstract
BACKGROUND AND AIMS
Chronic kidney disease (CKD) in type 2 diabetes (T2D) is the most common cause of kidney failure. Despite treatment advances, there is still a large unmet need to prevent CKD progression, which can increase the risk for cardiovascular (CV) disease and kidney failure. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have beneficial effects on glycaemic control and body weight. Some agents have also shown CV benefit and can be used in people with T2D regardless of CKD status (except in end-stage renal disease). CV outcomes trials have suggested that GLP-1RAs may have kidney-protective effects, reducing albuminuria and preserving estimated glomerular filtration rate (eGFR). FLOW (NCT03819153) is a dedicated kidney outcomes trial designed to evaluate the effect of the once-weekly (OW) GLP-1RA semaglutide on major kidney outcomes in subjects with T2D and CKD; we report the blinded baseline characteristics of the FLOW trial population.
METHOD
FLOW is an ongoing randomized, double-blinded, multinational, phase 3b trial in which 3535 subjects with T2D with an eGFR ≥25–≤75 mL/min/1.73 m², and urine albumin-to-creatinine ratio (UACR) >100 to <5000 mg/g were randomly assigned 1:1 to OW semaglutide 1.0 mg or placebo, as add-on to standard-of-care (including maximum labelled/tolerated renin–angiotensin–aldosterone system inhibitors). The primary endpoint is the time to first occurrence of kidney failure (as measured by persistent eGFR <15 mL/min/1.73 m² or initiation of chronic dialysis or kidney transplantation); ≥50% persistent eGFR reduction compared with baseline; and kidney or CV death.
RESULTS
Baseline characteristics from FLOW are shown in the Table 1. Overall, mean eGFR at baseline was 47.0 mL/min/1.73 m2 with 79.6% of subjects having an eGFR of <60 mL/min/1.73 m2. Median UACR at baseline was 567 mg/g, and 68.5% of subjects had macroalbuminuria (≥300 mg/g). According to Kidney Disease: Improving Global Outcomes categories, 24.8% of subjects were classified as high risk and 68.2% of subjects were classified as very high risk for CKD progression (Figure 1).
CONCLUSION
The FLOW trial will evaluate the efficacy and safety of semaglutide on kidney outcomes in subjects with T2D and high risk of kidney disease progression, a group for which additional therapies are urgently required.

Abstract
Abstract
BACKGROUND AND AIMS
Patients with stage 4 chronic kidney disease (CKD) and type 2 diabetes (T2D) have a high residual risk of cardiovascular (CV) and kidney disease progression, and effective treatment options to reduce the risk are limited. The non-steroidal selective mineralocorticoid receptor antagonist finerenone has previously demonstrated significant cardiorenal benefits versus placebo in patients with stage 1–4 CKD [1–3]. This FIDELITY subgroup analysis investigated the effects of finerenone in patients with stage 4 CKD [estimated glomerular filtration rate (eGFR) <30 mL/min/1.73 m2) versus those with stage 1–3 CKD (eGFR ≥ 30 mL/min/1.73 m2).
METHOD
FIDELIO-DKD and FIGARO-DKD were phase III trials of patients with CKD and T2D randomised 1:1 to finerenone or placebo. FIDELITY was an individual patient-level prespecified pooled efficacy and safety analysis of these studies. Efficacy outcomes included change in urine albumin-to-creatinine ratio (UACR) between baseline and month 4, change in eGFR over time, a kidney composite outcome (kidney failure, a sustained ≥57% decrease in eGFR from baseline over ≥ 4 weeks or renal death) and a CV composite outcome [CV death, non-fatal myocardial infarction, non-fatal stroke or hospitalization for heart failure (HHF)], as well as the individual components of these composite outcomes.
RESULTS
Of 13 023 patients included in the analysis, 890 patients (6.8%) had stage 4 CKD; key baseline characteristics are listed in Table 1. In patients with stage 4 CKD, finerenone reduced UACR by 31% vs placebo between baseline and month 4 [ratio of least-squares (LS) mean change 0.69; 95% confidence interval (CI) 0.63–0.77), an effect maintained for the duration of the study. Total eGFR slope (LS mean change in eGFR from randomisation to end of treatment) in patients with stage 4 CKD was –0.7 mL/min/1.73 m2/year with finerenone versus –1.6 mL/min/1.73 m2/year with placebo; the chronic eGFR slope (LS mean change in eGFR from month 4 to end of treatment) was –1.8 mL/min/1.73 m2/year with finerenone vs –3.2 mL/min/1.73 m2/year with placebo. The hazard ratio (HR) for risk of the kidney composite in stage 4 CKD was 1.01 (95% CI 0.75–1.37; Figure 1) for finerenone versus placebo. Reduction in risk of sustained ≥ 57% decrease in eGFR with finerenone (stage 4 CKD: HR 0.69, 95% CI 0.43–1.11) was similar between CKD subgroups (pinteraction = 0.71). Reduction in risk of the composite CV outcome (stage 4 CKD: HR 0.78, 95% CI 0.57–1.07) and HHF (stage 4 CKD: HR 0.99, 95% CI 0.62–1.58) was also consistent between CKD subgroups (pinteraction = 0.67 and 0.31, respectively). Overall, incidences of adverse events were balanced between treatment arms in patients with stage 4 CKD and stage 1–3 CKD. The incidence of hyperkalaemia leading to permanent discontinuation was low in patients with stage 4 CKD (3.2% versus 2.2% for finerenone versus placebo).
CONCLUSION
The cardiorenal benefits and safety profile of finerenone in FIDELITY were also observed in the subgroup of patients with stage 4 CKD.

Abstract
BACKGROUND AND OBJECTIVES The effect of including race in the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation on screening, recruitment, and outcomes of clinical trials is unclear. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS The inclusion and outcomes of participants in the Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial, which randomized individuals with type 2 diabetes and CKD to canagliflozin or placebo, were evaluated after calculating eGFR using the 2009 CKD-EPI creatinine equation with and without a race-specific coefficient or the 2021 CKD-EPI creatinine equation. Treatment effects were estimated using proportional hazards models and piecewise linear mixed effects models for eGFR slope. RESULTS Of 4401 randomized participants, 2931 (67%) were White participants, 224 (5%) were Black participants, 877 (20%) were Asian participants, and 369 (8%) participants were other race. Among randomized participants, recalculation of screening eGFR using the 2009 equation without a race-specific coefficient had no effect on the likelihood of non-Black participants meeting inclusion criteria but would have excluded 22 (10%) randomized Black participants for eGFR<30 ml/min per 1.73 m2. Recalculation with the 2021 equation would have excluded eight (4%) Black participants for low eGFR and one (0.4%) Black participant for eGFR≥90 ml/min per 1.73 m2, whereas 30 (0.7%) and 300 (7%) non-Black participants would have been excluded for low and high eGFR, respectively. A high proportion (eight of 22; 36%) of end points in Black participants occurred in individuals who would have been excluded following recalculation using the race-free 2009 equation but not when recalculated with the 2021 equation (one of eight; 13%). Cardiovascular and kidney treatment effects remained consistent across eGFR categories following recalculation with either equation. Changes in estimated treatment effects on eGFR slope were modest but were qualitatively larger following recalculation using the 2021 equation. However, the effect of canagliflozin on chronic change in eGFR was attenuated by 7% among Black participants and increased 6% in non-Black participants. CONCLUSIONS In the CREDENCE trial, eGFR recalculation without the race-specific coefficient had small but potentially important effects on event rates and the relative proportion of Black participants without substantially changing efficacy estimates.

Abstract
BACKGROUND Cell therapies explore unmet clinical needs of patients with chronic kidney disease with the potential to alter the pathway toward end-stage kidney disease. We describe the design and baseline patient characteristics of a phase II multicenter clinical trial utilizing the novel renal autologous cell therapy (REACT), by direct kidney parenchymal injection via the percutaneous approach in adults with type 2 diabetic kidney disease (T2DKD), to delay or potentially avoid renal replacement therapy. DESIGN The study conducted a prospective, multicenter, randomized control, open-label, phase II clinical trial between an active treatment group (ATG) receiving REACT from the beginning of the trial and a contemporaneous deferred treatment group (DTG) receiving standard of care for 12 months before crossing over to receive REACT. OBJECTIVES The objective of this study was to establish the safety and efficacy of 2 REACT injections with computed tomography guidance, into the renal cortex of patients with T2DKD administered 6 months apart, and to compare the longitudinal change in renal function between the ATG and the DTG. SETTING This was a multicenter study conducted in major US hospitals. PATIENTS We enrolled eighty-three adult patients with T2DKD, who have estimated glomerular filtration rates (eGFRs) between 20 and 50 mL/min/1.73 m2. METHODS All patients undergo an image-guided percutaneous kidney biopsy to obtain epithelial phenotype selective renal cells isolated from the kidney tissue that is then expanded ex vivo over 4-6 weeks, resulting in the REACT biologic product. Patients are randomized 1:1 into the ATG or the DTG. Primary efficacy endpoints for both study groups include eGFR measurements at baseline and at 3-month intervals, through 24 months after the last REACT injection. Safety analyses include biopsy-related complications, REACT injection, and cellular-related adverse events. The study utilizes Good Clinical and Manufacturing Practices and a Data and Safety Monitoring Board. The sample size confers a statistical power of 80% to detect an eGFR change in the ATG compared to the DTG at 24 months with an α = 0.05. LIMITATIONS Blinding cannot occur due to the intent to treat procedure, biopsy in both groups, and open trial design. CONCLUSION This multicenter phase II randomized clinical trial is designed to determine the efficacy and safety of REACT in improving or stabilizing renal function among patients with T2DKD stages 3a-4.

Abstract
INTRODUCTION Worsening kidney function (WKF) is frequent among patients with type 2 diabetes (T2D) and a recent acute coronary syndrome (ACS) and is associated with a poor prognosis. An accurate prediction of WKF is clinically important. AIMS Using data from the Cardiovascular Outcomes Study of Alogliptin in Patients with Type 2 Diabetes and Acute Coronary Syndrome trial including patients with T2D and a recent ACS, and a large biomarker panel incorporating proteins measured both in blood and urine, we aim to determine those with best performance for WKF prediction. METHODS WKF was defined as a ≥40% estimated glomerular filtration rate (eGFR) drop from baseline, eGFR <15 mL/min, or dialysis. Mixed-effects and time-updated Cox models were used. RESULTS 5,131 patients were included from whom 222 (4.3%) developed at least one WKF episode over a median follow-up of 18 months. Patients who developed WKF were more frequently women, had longer diabetes duration, a more frequent heart failure history, higher anemia prevalence, and impaired kidney function. In multivariable models including all variables (clinical and biomarkers) independently associated with WKF with a p value ≤0.0001, blood kidney injury molecule 1 (KIM-1) was (by far) the variable with strongest WKF association, followed by anemia. KIM-1 alone provided good discrimination for WKF prediction (area under the curve = 0.73). Patients in the high KIM-1-derived risk tertile had a 6.7-fold higher risk of any WKF than patients classified as low risk. In time-updated Cox models, the occurrence of WKF was independently associated with a higher risk of death: adjusted hazard ratio = 4.93 (3.06-7.96), p value <0.0001. CONCLUSION Blood KIM-1 was the biomarker with the strongest association with WKF. The occurrence of WKF was independently associated with a higher risk of subsequent cardiovascular events and mortality.

Abstract
Background Studies of the association of hypertension with incident colorectal cancer (CRC) may have been confounded by including individuals taking antihypertensive medication, at high risk for CRC (ie, colorectal polyps and inflammatory bowel disease), or with shared risk factors (eg, obesity and diabetes). We assessed whether adults with untreated hypertension are at higher risk for incident CRC compared with those with normal blood pressure (BP), and whether any association is evident among individuals without obesity or metabolic abnormalities. Methods and Results Analyses were conducted using a nationwide health claims database collected in the JMDC Claims Database between 2005 and 2018 (n=2 220 112; mean age, 44.1±11.0 years; 58.4% men). Participants who were taking antihypertensive medications or had a history of CRC, colorectal polyps, or inflammatory bowel disease were excluded. Each participant was categorized as having normal BP (systolic BP [SBP]<120 mm Hg and diastolic BP [DBP] <80 mm Hg, n=1 164 807), elevated BP (SBP 120–129 mm Hg and DBP <80 mm Hg, n=341 273), stage 1 hypertension (SBP 130–139 mm Hg or DBP 80–89 mm Hg, n=466 298), or stage 2 hypertension (SBP ≥140 mm Hg or DBP ≥90 mm Hg, n=247 734). Over a mean follow‐up of 1112±854 days, 6899 incident CRC diagnoses occurred. After multivariable adjustment, compared with normal BP, hazard ratios for incident CRC were 0.93 (95% CI, 0.85–1.01) for elevated BP, 1.07 (95% CI, 0.99–1.15) for stage 1 hypertension, and 1.17 (95% CI, 1.08–1.28) for stage 2 hypertension. The hazard ratios for incident CRC for each 10‐mm Hg‐higher SBP or DBP were 1.04 (95% CI, 1.02–1.06) and 1.06 (95% CI, 1.03–1.09), respectively. These associations were present among adults who did not have obesity, high waist circumference, diabetes, or dyslipidemia. Conclusions Higher SBP and DBP, and stage 2 hypertension are associated with a higher risk for incident CRC, even among those without shared risk factors for CRC. BP measurement could identify individuals at increased risk for subsequent CRC.

Early Response in Albuminuria and Long-Term Kidney Protection during Treatment with an Endothelin Receptor Antagonist: A Prespecified Analysis from the SONAR Trial. J Am Soc Nephrol 2021; 32:2900-2911.

Abstract
BACKGROUND Whether early reduction in albuminuria with atrasentan treatment predicts its long-term kidney-protective effect is unknown. METHODS To assess the long-term effects on kidney outcomes of atrasentan versus placebo in the SONAR trial, we enrolled patients who had type 2 diabetes and CKD (stage 2-4) and a urinary albumin creatinine ratio (UACR) of 300-5000 mg/g; participants were receiving maximum tolerated renin-angiotensin system inhibition. After 6 weeks exposure to 0.75 mg/day atrasentan (enrichment period), participants were randomized (stratified by UACR response during enrichment, ranging from ≤60% to >0%) to continue atrasentan or transition to placebo. Primary kidney outcome was a composite of sustained serum creatinine doubling or ESKD. RESULTS UACR response to atrasentan during enrichment persisted throughout the double-blind treatment phase and predicted the primary kidney outcome, whereas UACR levels with placebo remained below pre-enrichment values in the two highest UACR response strata, and exceeded pre-enrichment values in the two lowest strata. As a result, early UACR response to atrasentan during enrichment was also associated with the primary kidney outcome during placebo. Accordingly, the predictive effect of early albuminuria changes during atrasentan was eliminated after placebo correction, leading to a consistent relative risk reduction for the primary kidney outcome with atrasentan compared with placebo, irrespective of the initial UACR response. The difference between atrasentan and placebo in UACR during double-blind treatment was also consistent across UACR response strata. CONCLUSIONS Our findings do not support UACR response as a causal predictor of atrasentan's treatment effect. However, the variable trajectory in UACR with placebo, aspects of the trial design, day-to-day variability in albuminuria, and potential long-lasting effects of atrasentan may have contributed.

Abstract
Abstract
Background
Hyperkalaemia is a common complication of type 2 diabetes mellitus (T2DM) and limits the optimal use of agents that block the renin-angiotensin aldosterone system (RAAS), particularly in patients with chronic kidney disease (CKD). In patients with CKD, sodium glucose cotransporter 2 (SGLT2) inhibitors provide cardiorenal protection, but whether they affect the risk of hyperkalaemia remains uncertain.
Purpose
We sought to assess the effect of canagliflozin on hyperkalaemia and other potassium-related outcomes in people with T2DM and CKD by conducting a post-hoc analysis of the CREDENCE trial.
Methods
The CREDENCE trial randomized 4401 participants with T2DM and CKD to the SGLT2 inhibitor canagliflozin or matching placebo. In this post-hoc analysis using an intention-to-treat approach, we assessed the effect of canagliflozin on a composite outcome of time to either investigator-reported hyperkalaemia or the initiation of potassium binders. We also analysed effects on central laboratory-determined hyper- and hypokalaemia (serum potassium ≥6.0 and <3.5 mmol/L, respectively) and change in serum potassium.
Results
At baseline the mean serum potassium in canagliflozin and placebo arms was 4.5 mmol/L; 4395 (99.9%) participants were receiving renin angiotensin system blockade. Canagliflozin reduced the risk of investigator-reported hyperkalaemia or initiation of potassium binders (HR 0.78, 95% CI 0.64–0.95, p=0.014; Figure 1). The incidence of laboratory-determined hyperkalaemia was similarly reduced (HR 0.77, 95% CI 0.61–0.98, p=0.031; Figure 2); the risk of hypokalaemia (HR 0.92, 95% CI 0.71–1.20, p=0.53) was not increased. Mean serum potassium over time with canagliflozin was similar to that of placebo.
Conclusion
Among patients treated with RAAS inhibitors, SGLT2 inhibition with canagliflozin may reduce the risk of hyperkalaemia in people with T2DM and CKD without increasing the risk of hypokalaemia.

Abstract
INTRODUCTION Resistant hypertension (RH) is more prevalent in the advanced stages of chronic kidney disease (CKD) and contributes to a greater likelihood of poor cardiovascular and renal outcomes. However, RH often goes untreated in this population as the currently available recommended add-on therapy, steroidal mineralocorticoid receptor antagonists (MRAs) such as spironolactone and eplerenone, may lead to unacceptable side effects, mainly hyperkalemia in a cohort with reduced kidney function. KBP-5074 is a novel non-steroidal MRA that addresses the unmet need of treating RH in the CKD population without hyperkalemia. AREAS COVERED We provide an overview of the current state of RH treatment in stage 3B/4 CKD as it relates to available steroidal MRAs and the current limitations of this treatment. We then explore the emerging data on nonsteroidal MRAs, particularly the novel agent KBP-5074 and its applicability to treatment in this context. EXPERT OPINION In a randomized, double-blind, placebo-controlled phase 2b trial, the novel nonsteroidal MRA KBP-5074 demonstrated clinical efficacy and safety in treating RH in stage 3B/4 CKD and offers a potential new treatment option in this population at high risk for cardiovascular disease (CVD) and CKD progression.

Abstract
BACKGROUND Patients with type 2 diabetes (T2D) may experience frequent body weight changes over time. The prognostic impact of these weight changes (gains or losses) requires further study. AIMS To study the associations between changes in body weight (intentional or unintentional) with subsequent outcomes. METHODS The EXAMINE trial included 5380 patients with T2D and a recent acute coronary syndrome, who were randomized to alogliptin or placebo. Time-updated Cox models and mixed effects models were used to test the associations between changes in body weight and subsequent outcomes over a median follow-up of 1.6 (1.0-2.1) years. RESULTS During the post-randomization follow-up period, 1044 patients (19.4%) experienced a weight loss ≥ 5% of baseline weight, 2677 (49.8%) had a stable weight, and 1659 (30.8%) had a ≥ 5 % weight gain. Patients with weight loss were more frequently women and had more co-morbid conditions. In contrast, patients who gained ≥ 5% weight were more frequently men with less co-morbid conditions. A weight loss ≥ 5% was independently associated with a higher risk of subsequent adverse outcomes, including all-cause mortality: adjusted HR (95% CI) = 1.79 (1.33-2.42), P < 0.001. Similar associations were found for cardiovascular mortality, the composite of cardiovascular mortality or heart failure hospitalization, and the primary outcome. A weight gain ≥ 5% was independently associated with an increase in the risk of subsequent cardiovascular mortality or heart failure hospitalization only: adjusted HR (95% CI) = 1.34 (1.02-1.76), P = 0.033. CONCLUSIONS In patients with T2D who had a recent ACS/MI, a ≥ 5% loss of body weight was associated with a higher risk of subsequent cardiovascular events and mortality.

The effects of canagliflozin on heart failure and cardiovascular death by baseline participant characteristics: Analysis of the CREDENCE trial. Diabetes Obes Metab 2021; 23:1652-1659.

Abstract
Heart failure is prevalent in those with type 2 diabetes and chronic kidney disease, and is associated with significant mortality and morbidity. In the CREDENCE trial, canagliflozin reduced the risk of hospitalization for heart failure (HHF) or cardiovascular (CV) death by 31%. In the current analysis we sought to determine whether the effect of canagliflozin on HHF/CV death differed in subgroups defined by key baseline participant characteristics. Cox regression models were used to estimate hazard ratios and 95% confidence intervals. Canagliflozin was associated with a reduction in the relative risk of HHF/CV death regardless of age, sex, history of heart failure or CV disease, and the use of loop diuretics or glucagon-like peptide-1 receptor agonists (all pinteraction > .114). The absolute benefit of canagliflozin was greater in those at highest baseline risk, such as those with CV disease (50 fewer events/1000 patients treated over 2.5 years vs. 20 fewer events in those without CV disease) or advanced kidney disease (estimated glomerular filtration rate [eGFR] 30-45 mL/min/1.73m2 : 61 events prevented/1000 patients treated over 2.5 years vs. 23 events in eGFR 60-90 mL/min/1.73m2 ). Canagliflozin consistently reduces the proportional risk of HHF/CV death across a broad range of subgroups with greater absolute benefits in those at highest baseline risk.

Abstract
AIM To determine the clinical correlates of increased red blood cell distribution width (RDW), its potential mechanistic association with multiple circulating biomarkers, and its prognostic value in patients with type 2 diabetes (T2D) who had a recent acute coronary syndrome. METHODS We used time-updated Cox models applied to patients enrolled in the Examination of Cardiovascular Outcomes with Alogliptin versus Standard of Care (EXAMINE) trial. RESULTS A total of 5380 patients were included, the median age was 61 years and 32% were women. Patients with higher RDW were older, more frequently women, with a longer diabetes duration and increased co-morbidities. An RDW of more than 16.1% (both baseline and time-updated) was independently associated with the study primary composite outcome of non-fatal myocardial infarction, non-fatal stroke or cardiovascular death (time-updated adjusted HR = 1.36, 95% CI = 1.16-1.61, p < .001), all-cause death (time-updated adjusted HR = 2.01, 95% CI = 1.60-2.53, p < .001), as well as mortality from non-cardiovascular causes (time-updated adjusted HR = 2.67, 95% CI = 1.72-4.15, p < .001). RDW had a weak-to-moderate correlation with haemoglobin and circulating markers that reflected inflammation, apoptosis, fibrosis and congestion. Alogliptin did not alter RDW values. CONCLUSIONS RDW is a marker of disease severity associated with a multitude of poor outcomes, including both cardiovascular and non-cardiovascular death. RDW correlated modestly with inflammatory, pro-apoptotic, pro-fibrotic and congestion markers, and its levels were not affected by alogliptin during the course of the trial.
