Item Effect of Canagliflozin on Total Cardiovascular Burden in Patients With Diabetes and Chronic Kidney Disease: A Post Hoc Analysis From the CREDENCE Trial(American Heart Association, 2022) Li, Jing-Wei; Arnott, Clare; Heerspink, Hiddo J.L.; Li, Qiang; Cannon, Christopher P.; Wheeler, David C.; Charytan, David M.; Barraclough, Jennifer; Figtree, Gemma A.; Agarwal, Rajiv; Bakris, George; de Zeeuw, Dick; Greene, Tom; Levin, Adeera; Pollock, Carol; Zhang, Hong; Zinman, Bernard; Mahaffey, Kenneth W.; Perkovic, Vlado; Neal, Bruce; Jardine, Meg J.; Medicine, School of MedicineBackground: 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.Item Effects of Canagliflozin in Patients with Baseline eGFR <30 ml/min per 1.73 m2: Subgroup Analysis of the Randomized CREDENCE Trial(Wolters Kluwer, 2020-12-07) Bakris, George; Oshima, Megumi; Mahaffey, Kenneth W.; Agarwal, Rajiv; Cannon, Christopher P.; Capuano, George; Charytan, David M.; de Zeeuw, Dick; Edwards, Robert; Greene, Tom; Heerspink, Hiddo J.L.; Levin, Adeera; Neal, Bruce; Oh, Richard; Pollock, Carol; Rosenthal, Norman; Wheeler, David C.; Zhang, Hong; Zinman, Bernard; Jardine, Meg J.; Perkovic, Vlado; Medicine, School of MedicineBackground and objectives: The Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial demonstrated that the sodium glucose cotransporter 2 (SGLT2) inhibitor canagliflozin reduced the risk of kidney failure and cardiovascular events in participants with type 2 diabetes mellitus and CKD. Little is known about the use of SGLT2 inhibitors in patients with eGFR <30 ml/min per 1.73 m2. The participants in the CREDENCE study had type 2 diabetes mellitus, a urinary albumin-creatinine ratio >300-5000 mg/g, and an eGFR of 30 to <90 ml/min per 1.73 m2 at screening. This post hoc analysis evaluated participants with eGFR <30 ml/min per 1.73 m2 at randomization. Design, setting, participants, & measurements: Effects of eGFR slope through week 130 were analyzed using a piecewise, linear, mixed-effects model. Efficacy was analyzed in the intention-to-treat population, on the basis of Cox proportional hazard models, and safety was analyzed in the on-treatment population. At randomization (an average of 29 days after screening), 174 of 4401 (4%) participants had an eGFR <30 ml/min per 1.73 m2 (mean [SD] eGFR, 26 [3] ml/min per 1.73 m2). Results: From weeks 3 to 130, there was a 66% difference in the mean rate of eGFR decline with canagliflozin versus placebo (mean slopes, -1.30 versus -3.83 ml/min per 1.73 m2 per year; difference, -2.54 ml/min per 1.73 m2 per year; 95% confidence interval [CI], 0.90 to 4.17). Effects of canagliflozin on kidney, cardiovascular, and mortality outcomes were consistent for those with eGFR <30 and ≥30 ml/min per 1.73 m2 (all P interaction >0.20). The estimate for kidney failure in participants with eGFR <30 ml/min per 1.73 m2 (hazard ratio, 0.67; 95% CI, 0.35 to 1.27) was similar to those with eGFR ≥30 ml/min per 1.73 m2 (hazard ratio, 0.70; 95% CI, 0.54 to 0.91; P interaction=0.80). There was no imbalance in the rate of kidney-related adverse events or AKI associated with canagliflozin between participants with eGFR <30 and ≥30 ml/min per 1.73 m2 (all P interaction >0.12). Conclusions: This post hoc analysis suggests canagliflozin slowed progression of kidney disease, without increasing AKI, even in participants with eGFR <30 ml/min per 1.73 m2.Item Renal, Cardiovascular, and Safety Outcomes of Canagliflozin by Baseline Kidney Function: A Secondary Analysis of the CREDENCE Randomized Trial(American Society of Nephrology, 2020-05) Jardine, Meg J.; Zhou, Zien; Mahaffey, Kenneth W.; Oshima, Megumi; Agarwal, Rajiv; Bakris, George; Bajaj, Harpreet S.; Bull, Scott; Cannon, Christopher P.; Charytan, David M.; de Zeeuw, Dick; Di Tanna, Gian Luca; Greene, Tom; Heerspink, Hiddo J.L.; Levin, Adeera; Neal, Bruce; Pollock, Carol; Qiu, Rose; Sun, Tao; Wheeler, David C.; Zhang, Hong; Zinman, Bernard; Rosenthal, Norman; Perkovic, Vlado; Medicine, School of MedicineBackground: Canagliflozin reduced renal and cardiovascular events in people with type 2 diabetes in the CREDENCE trial. We assessed efficacy and safety of canagliflozin by initial estimated glomerular filtration rate (eGFR). Methods: CREDENCE randomly assigned 4401 participants with an eGFR of 30 to <90 ml/min per 1.73 m2 and substantial albuminuria to canagliflozin 100 mg or placebo. We used Cox proportional hazards regression to analyze effects on renal and cardiovascular efficacy and safety outcomes within screening eGFR subgroups (30 to <45, 45 to <60, and 60 to <90 ml/min per 1.73 m2) and linear mixed effects models to analyze the effects on eGFR slope. Results: At screening, 1313 (30%), 1279 (29%), and 1809 (41%) participants had an eGFR of 30 to <45, 45 to <60, and 60 to <90 ml/min per 1.73 m2, respectively. The relative benefits of canagliflozin for renal and cardiovascular outcomes appeared consistent among eGFR subgroups (all P interaction >0.11). Subgroups with lower eGFRs, who were at greater risk, exhibited larger absolute benefits for renal outcomes. Canagliflozin's lack of effect on serious adverse events, amputations, and fractures appeared consistent among eGFR subgroups. In all subgroups, canagliflozin use led to an acute eGFR drop followed by relative stabilization of eGFR loss. Among those with an eGFR of 30 to <45 ml/min per 1.73 m2, canagliflozin led to an initial drop of 2.03 ml/min per 1.73 m2. Thereafter, decline in eGFR was slower in the canagliflozin versus placebo group (-1.72 versus -4.33 ml/min per 1.73 m2; between-group difference 2.61 ml/min per 1.73 m2). Conclusions: Canagliflozin safely reduced the risk of renal and cardiovascular events, with consistent results across eGFR subgroups, including the subgroup initiating treatment with an eGFR of 30 to <45 ml/min per 1.73 m2. Absolute benefits for renal outcomes were greatest in subgroups with lower eGFR.Item Risk Factors for Fracture in Patients with Coexisting Chronic Kidney Disease and Type 2 Diabetes: An Observational Analysis from the CREDENCE Trial(Hindawi, 2022-05-27) Young, Tamara K.; Toussaint, Nigel D.; Di Tanna, Gian Luca; Arnott, Clare; Hockham, Carinna; Kang, Amy; Schutte, Aletta E.; Perkovic, Vlado; Mahaffey, Kenneth W.; Agarwal, Rajiv; Bakris, George L.; Charytan, David M.; Heerspink, Hiddo J.L.; Levin, Adeera; Pollock, Carol; Wheeler, David C.; Zhang, Hong; Jardine, Meg J.; Medicine, School of MedicineBackground: The fracture pathophysiology associated with type 2 diabetes and chronic kidney disease (CKD) is incompletely understood. We examined individual fracture predictors and prediction sets based on different pathophysiological hypotheses, testing whether any of the sets improved prediction beyond that based on traditional osteoporotic risk factors. Methods: Within the CREDENCE cohort with adjudicated fracture outcomes, we assessed the association of individual factors with fracture using Cox regression models. We used the Akaike information criteria (AIC) and Schwartz Bayes Criterion (SBC) to assess six separate variable sets based on hypothesized associations with fracture, namely, traditional osteoporosis, exploratory general population findings, cardiovascular risk, CKD-mineral and bone disorder, diabetic osteodystrophy, and an all-inclusive set containing all variables. Results: Fracture occurred in 135 (3.1%) participants over a median 2.35 [1.88-2.93] years. Independent fracture predictors were older age (hazard ratio [HR] 1.04, confidence interval [CI] 1.01-1.06), female sex (HR 2.49, CI 1.70-3.65), previous fracture (HR 2.30, CI 1.58-3.34), Asian race (HR 1.74, CI 1.09-2.78), vitamin D therapy requirement (HR 2.05, CI 1.31-3.21), HbA1c (HR 1.14, CI 1.00-1.32), prior cardiovascular event (HR 1.60, CI 1.10-2.33), and serum albumin (HR 0.41, CI 0.23-0.74) (lower albumin associated with greater risk). The goodness of fit of the various hypothesis sets was similar (AIC range 1870.92-1849.51, SBC range 1875.60-1948.04). Conclusion: Independent predictors of fracture were identified in the CREDENCE participants with type 2 diabetes and CKD. Fracture prediction was not improved by models built on alternative pathophysiology hypotheses compared with traditional osteoporosis predictors.Item The impact of canagliflozin on the risk of neuropathy events: A post-hoc exploratory analysis of the CREDENCE trial(Elsevier, 2022) Liao, Jinlan; Kang, Amy; Xia, Chao; Young, Tamara; Di Tanna, Gian Luca; Arnott, Clare; Pollock, Carol; Krishnan, Arun V.; Agarwal, Rajiv; Bakris, George; Charytan, David M.; de Zeeuw, Dick; Heerspink, Hiddo J.L.; Levin, Adeera; Neal , Bruce; Wheeler, David C.; Zhang, Hong; Zinman, Bernard; Mahaffey, Kenneth W.; Perkovic, Vlado; Jardine, Meg J.; Smyth , Brendan; Medicine, School of MedicineAim: Canagliflozin reduces the risk, and progression, of diabetic kidney disease. We hypothesized that it may improve the microvascular complication of neuropathy. Methods: The CREDENCE trial randomized participants with type 2 diabetes and kidney disease to canagliflozin 100 mg daily or placebo. Neuropathy events were defined post-hoc as any reported adverse event consistent with a peripheral or autonomic neuropathy event. The effect of canagliflozin and predictors of neuropathy events were estimated using Cox regression analysis. In sensitivity analyses the endpoint was restricted to sensorimotor polyneuropathy, diabetic neuropathy, and non-autonomic neuropathy events. Results: Almost half (48.8%) of the 4401 participants had a diagnosis of neuropathy at baseline. Over a median of 2.45 years of follow up, 657 people experienced a neuropathy event (63.2 per 1000 patient-years). Independent factors associated with higher risk of experiencing neuropathy events were non-white race, younger age, higher glycated haemoglobin and lower estimated glomerular filtration rate. The incidence of neuropathy events was similar in people randomized to canagliflozin and placebo (334/2202 vs. 323/2199; HR 1.04, 95% CI 0.89 to 1.21, P = 0.66). Canagliflozin had no impact on sensorimotor polyneuropathy (HR 0.93, 95% CI 0.69 to 1.25, P = 0.63), diabetic neuropathy (HR 0.91, 95% CI 0.68 to 1.22, P = 0.52), or non-autonomic neuropathy (HR 1.03, 95% CI 0.87 to 1.21, P = 0.77). The lack of effect on neuropathy events was consistent in subgroup analyses. Conclusion: Canagliflozin did not affect the risk of neuropathy events in the CREDENCE trial. Future large randomized studies with prespecified neuropathy endpoints are required to determine the impact of sodium glucose cotransporter 2 inhibitors on diabetic neuropathy.
