    (American Heart Association, 2021) Ye, Nan; Jardine, Meg J.; Oshima, Megumi; Hockham, Carinna; Heerspink, Hiddo J. L.; Agarwal, Rajiv; Bakris, George; Schutte, Aletta E.; Arnott, Clare; Chang, Tara I.; Górriz, Jose L.; Cannon, Christopher P.; Charytan, David M.; de Zeeuw, Dick; Levin, Adeera; Mahaffey, Kenneth W.; Neal, Bruce; Pollock, Carol; Wheeler, David C.; Di Tanna, Gian Luca; Cheng, Hong; Perkovic, Vlado; Neuen, Brendon L.; Medicine, School of Medicine
    Background: People with type 2 diabetes and chronic kidney disease experience a high burden of hypertension, but the magnitude and consistency of blood pressure (BP) lowering with canagliflozin in this population are uncertain. Whether the effects of canagliflozin on kidney and cardiovascular outcomes vary by baseline BP or BP-lowering therapy is also unknown. Methods: The CREDENCE trial (Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation) randomized people with type 2 diabetes and chronic kidney disease to canagliflozin or placebo. In a post hoc analysis, we investigated the effect of canagliflozin on systolic BP across subgroups defined by baseline systolic BP, number of BP-lowering drug classes, and history of apparent treatment-resistant hypertension (BP ≥130/80 mm Hg while receiving ≥3 classes of BP-lowering drugs, including a diuretic). We also assessed whether effects on clinical outcomes differed across these subgroups. Results: The trial included 4401 participants, of whom 3361 (76.4%) had baseline systolic BP ≥130 mm Hg, and 1371 (31.2%) had resistant hypertension. By week 3, canagliflozin reduced systolic BP by 3.50 mm Hg (95% CI, -4.27 to -2.72), an effect maintained over the duration of the trial, with similar reductions across BP and BP-lowering therapy subgroups (all P interaction ≥0.05). Canagliflozin also reduced the need for initiation of additional BP-lowering agents during the trial (hazard ratio, 0.68 [95% CI, 0.61-0.75]). The effect of canagliflozin on kidney failure, doubling of serum creatinine, or death caused by kidney or cardiovascular disease (hazard ratio, 0.70 [95% CI, 0.59-0.82]) was consistent across BP and BP-lowering therapy subgroups (all P interaction ≥0.35), as were effects on other key kidney, cardiovascular, and safety outcomes. Conclusions: In people with type 2 diabetes and chronic kidney disease, canagliflozin lowers systolic BP across all BP-defined subgroups and reduces the need for additional BP-lowering agents. These findings support use of canagliflozin for end-organ protection and as an adjunct BP-lowering therapy in people with chronic kidney disease.

    Canagliflozin and Renal Outcomes in Type 2 Diabetes and Nephropathy
    (Massachusetts Medical Society, 2019-06) Perkovic, Vlado; Jardine, Meg J.; Neal, Bruce; Bompoint, Severine; Heerspink, Hiddo J. L.; Charytan, David M.; Edwards, Robert; Agarwal, Rajiv; Bakris, George; Bull, Scott; Cannon, Christopher P.; Capuano, George; Medicine, School of Medicine
    BACKGROUND Type 2 diabetes mellitus is the leading cause of kidney failure worldwide, but few effective long-term treatments are available. In cardiovascular trials of inhibitors of sodium–glucose cotransporter 2 (SGLT2), exploratory results have suggested that such drugs may improve renal outcomes in patients with type 2 diabetes. METHODS In this double-blind, randomized trial, we assigned patients with type 2 diabetes and albuminuric chronic kidney disease to receive canagliflozin, an oral SGLT2 inhibitor, at a dose of 100 mg daily or placebo. All the patients had an estimated glomerular filtration rate (GFR) of 30 to <90 ml per minute per 1.73 m2 of body-surface area and albuminuria (ratio of albumin [mg] to creatinine [g], >300 to 5000) and were treated with renin–angiotensin system blockade. The primary outcome was a composite of end-stage kidney disease (dialysis, transplantation, or a sustained estimated GFR of <15 ml per minute per 1.73 m2), a doubling of the serum creatinine level, or death from renal or cardiovascular causes. Prespecified secondary outcomes were tested hierarchically. RESULTS The trial was stopped early after a planned interim analysis on the recommendation of the data and safety monitoring committee. At that time, 4401 patients had undergone randomization, with a median follow-up of 2.62 years. The relative risk of the primary outcome was 30% lower in the canagliflozin group than in the placebo group, with event rates of 43.2 and 61.2 per 1000 patient-years, respectively (hazard ratio, 0.70; 95% confidence interval [CI], 0.59 to 0.82; P=0.00001). The relative risk of the renal-specific composite of end-stage kidney disease, a doubling of the creatinine level, or death from renal causes was lower by 34% (hazard ratio, 0.66; 95% CI, 0.53 to 0.81; P<0.001), and the relative risk of end-stage kidney disease was lower by 32% (hazard ratio, 0.68; 95% CI, 0.54 to 0.86; P=0.002). The canagliflozin group also had a lower risk of cardiovascular death, myocardial infarction, or stroke (hazard ratio, 0.80; 95% CI, 0.67 to 0.95; P=0.01) and hospitalization for heart failure (hazard ratio, 0.61; 95% CI, 0.47 to 0.80; P<0.001). There were no significant differences in rates of amputation or fracture. CONCLUSIONS In patients with type 2 diabetes and kidney disease, the risk of kidney failure and cardiovascular events was lower in the canagliflozin group than in the placebo group at a median follow-up of 2.62 years.

    Canagliflozin, Blood Pressure Variability, and Risk of Cardiovascular, Kidney, and Mortality Outcomes: Pooled Individual Participant Data From the CANVAS and CREDENCE Trials
    (American Heart Association, 2023) Fletcher, Robert A.; Arnott, Clare; Rockenschaub, Patrick; Schutte, Aletta E.; Carpenter, Lewis; Vaduganathan, Muthiah; Agarwal, Rajiv; Bakris, George; Chang, Tara I.; Heerspink, Hiddo J. L.; Jardine, Meg J.; Mahaffey, Kenneth W.; Neal, Bruce; Pollock, Carol; Jun, Min; Rodgers, Anthony; Perkovic, Vlado; Neuen, Brendon L.; Medicine, School of Medicine
    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.

    Effects of canagliflozin on cardiovascular, renal, and safety outcomes in participants with type 2 diabetes and chronic kidney disease according to history of heart failure: Results from the CREDENCE trial
    (Elsevier, 2021) Sarraju, Ashish; Li, JingWei; Cannon, Christopher P.; Chang, Tara I.; Agarwal, Rajiv; Bakris, George; Charytan, David M.; de Zeeuw, Dick; Greene, Tom; Heerspink, Hiddo J. L.; Levin, Adeera; Neal, Bruce; Pollock, Carol; Wheeler, David C.; Yavin, Yshai; Zhang, Hong; Zinman, Bernard; Perkovic, Vlado; Jardine, Meg; Mahaffey, Kenneth W.; Medicine, School of Medicine
    We aimed to assess the efficacy and safety of canagliflozin in patients with type 2 diabetes and nephropathy according to prior history of heart failure in the Canagliflozin and Renal Events in Diabetes With Established Nephropathy Clinical Evaluation (CREDENCE) trial. We found that participants with a prior history of heart failure at baseline (15%) were more likely to be older, female, white, have a history of atherosclerotic cardiovascular disease, and use diuretics and beta blockers (all P < .001), and that, compared with placebo, canagliflozin safely reduced renal and cardiovascular events with consistent effects in patients with and without a prior history of heart failure (all efficacy P interaction >.150). These results support the efficacy and safety of canagliflozin in patients with type 2 diabetes and nephropathy regardless of prior history of heart failure.

    Insights from CREDENCE trial indicate an acute drop in estimated glomerular filtration rate during treatment with canagliflozin with implications for clinical practice
    (Elsevier, 2021) Oshima, Megumi; Jardine, Meg J.; Agarwal, Rajiv; Bakris, George; Cannon, Christopher P.; Charytan, David M.; de Zeeuw, Dick; Edwards, Robert; Greene, Tom; Levin, Adeera; Lim, Soo Kun; Mahaffey, Kenneth W.; Neal, Bruce; Pollock, Carol; Rosenthal, Norman; Wheeler, David C.; Zhang, Hong; Zinman, Bernard; Perkovic, Vlado; Heerspink, Hiddo J. L.; Medicine, School of Medicine
    Canagliflozin slows the progression of chronic kidney disease in patients with type 2 diabetes and induces a reversible acute drop in estimated glomerular filtration rate (eGFR), believed to be a hemodynamic effect. Predictors of the initial drop and its association with long-term eGFR trajectories and safety outcomes are unknown. To assess this, we performed a post-hoc analysis of 4289 participants in the CREDENCE trial with type 2 diabetes and chronic kidney disease equally split into treatment and placebo groups who had eGFR measured at both baseline and week three. The eGFR was categorized at week three as greater than a 10% decline; between 0 and 10% decline; and no decline. Long-term eGFR trajectories and safety outcomes were estimated in each category of acute eGFR change by linear mixed effects models and Cox regression after adjustment for baseline characteristics and medications use. Significantly more participants in the canagliflozin (45%) compared to the placebo (21%) group experienced an acute drop in eGFR over 10%. An over 30% drop occurred infrequently (4% of participants with canagliflozin and 2% with placebo). The odds ratio for a drop in eGFR over 10% with canagliflozin compared to placebo was significant at 3.03 (95% confidence interval 2.65, 3.47). Following the initial drop in eGFR, multivariable adjusted long-term eGFR trajectories, as well as overall and kidney safety profiles, in those treated with canagliflozin were similar across eGFR decline categories. Thus, although acute drops in eGFR over 10% occurred in nearly half of all participants following initiation of canagliflozin, the clinical benefit of canagliflozin was observed regardless. Additionally, safety outcomes were similar among subgroups of acute eGFR drop.
