Background: The prognosis of individuals with and without an established heart failure (HF) diagnosis and similarly elevated N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels is not well-known.
Methods And Results: CANVAS (Canagliflozin Cardiovascular Assessment Study) trial participants were stratified according to baseline NT-proBNP quartiles and history of HF at baseline. Adjusted event rates per 1000 patient-years of follow-up for hospitalizations for HF, cardiovascular mortality, and kidney events were assessed, and hazard ratios (HR) were calculated using Cox proportional hazard models.
Objective: To examine whether the circulating substrate mix may be related to the incidence of heart failure (HF) and cardiovascular (CV) mortality and how it is altered by canagliflozin treatment.
Research Design And Methods: We measured fasting glucose, free fatty acids (FFA), glycerol, β-hydroxybutyrate, acetoacetate, lactate, and pyruvate concentrations in 3,581 samples from the CANagliflozin cardioVascular Assessment Study (CANVAS) trial at baseline and at 1 and 2 years after randomization. Results were analyzed by univariate and multivariate Cox proportional hazards models.
Background: Circulating biomarkers reflecting different mechanistic pathways may identify at-risk individuals with diabetes who may benefit from sodium-glucose cotransporter-2 (SGLT2) inhibitors.
Objectives: The purpose of this study was to determine if high-sensitivity cardiac troponin T (hs-cTnT), soluble suppression of tumorigenesis-2 (sST2), and insulin-like growth factor binding protein 7 (IGFBP7) levels, either alone or in combination, may modify the treatment benefits of canagliflozin.
Methods: In the CANVAS (CANagliflozin cardioVascular Assessment Study) biomarker substudy, we evaluated the prognostic significance of baseline biomarker measurements, the long-term trajectory of each, and response to canagliflozin on key cardiovascular and kidney outcomes.
Background Studies have suggested that sodium glucose co-transporter 2 inhibitors exert anti-inflammatory effects. We examined the association of baseline growth differentiation factor-15 (GDF-15), a marker of inflammation and cellular injury, with cardiovascular events, hospitalization for heart failure (HF), and kidney outcomes in patients with type 2 diabetes in the CANVAS (Canagliflozin Cardiovascular Assessment Study) and determined the effect of the sodium glucose co-transporter 2 inhibitor canagliflozin on circulating GDF-15. Methods and Results The CANVAS trial randomized 4330 people with type 2 diabetes at high cardiovascular risk to canagliflozin or placebo.

Methods And Results: Individuals with type 2 diabetes and history or high risk of cardiovascular disease (CANVAS Programme) or type 2 diabetes and chronic kidney disease (CREDENCE) were included. The intervention was canagliflozin 100 or 300 mg (combined in the analysis) or placebo.
Objective: To analyze the association between concentrations of plasma insulin-like growth factor binding protein 7 (IGFBP7) with renal and cardiac outcomes among participants with type 2 diabetes and high cardiovascular risk.
Research Design And Methods: Associations between IGFBP7 levels and clinical outcomes were assessed among participants in the Canagliflozin Cardiovascular Assessment Study (CANVAS) with type 2 diabetes and high cardiovascular risk.
Results: Among CANVAS participants, 3,577 and 2,898 had IGFBP7 measured at baseline and 1 year, respectively.
Background: Canagliflozin reduces cardiovascular events including hospitalization for heart failure (HHF) in patients with type 2 diabetes and cardiovascular risk. Elevated amino-terminal pro-B-type natriuretic peptide (NT-proBNP) concentrations are associated with HF diagnosis and predict cardiovascular risk.
Objectives: The purpose of this study was to measure NT-proBNP in CANVAS (Canagliflozin Cardiovascular Assessment Study) participants.
Background: Sodium glucose co-transporter 2 (SGLT2) inhibitors and glucagon-like peptide-1 receptor agonists (GLP1-RA) reduce cardiovascular events, and improve intermediate markers of cardiometabolic health, in those with type 2 diabetes. We investigated these effects in the CANVAS Program.
Methods And Results: The CANVAS Program comprised 2 double-blind, randomized, placebo-controlled trials (CANVAS and CANVAS-R) done in patients with type 2 diabetes and elevated cardiovascular risk.
Aims: Sodium glucose co-transporter 2 (SGLT2) inhibitors reduce several cardiovascular risk factors, including plasma glucose, blood pressure, albuminuria and body weight. Long-term treatment lowers risks of cardiovascular and renal events. The objective of this post hoc analysis was to determine the effects of canagliflozin treatment versus placebo on clinical outcomes in relation to body mass index (BMI).

View Article and Find Full Text PDFTwo large cardiovascular outcome trials of canagliflozin, comprising the CANVAS Program, will complete in early 2017: the CANagliflozin cardioVascular Assessment Study (CANVAS) and the CANagliflozin cardioVascular Assessment Study-Renal (CANVAS-R). Accruing data for the sodium glucose co-transporter 2 (SGLT2) inhibitor class has identified questions and opportunities that were not apparent when the trials were designed. Accordingly, a series of modifications have been made to the planned analyses.
View Article and Find Full Text PDFAims: The primary aim of the CANagliflozin cardioVascular Assessment Study-Renal (CANVAS-R) is to determine whether the favourable effects of inhibition of the sodium glucose co-transporter 2 (SGLT2) on blood glucose, blood pressure and body weight are accompanied by protection against adverse renal outcomes.
Materials And Methods: CANVAS-R is a prospective, randomized, double-blind, placebo-controlled trial in patients with type 2 diabetes with a history or high risk of cardiovascular events. Patients were randomly assigned to once-daily placebo or canagliflozin 100 mg (with optional uptitration to 300 mg) for a planned average of 2.
Objective: Reduced efficacy has been reported in the elderly; it may be a consequence of an age-dependent decline in estimated glomerular filtration rate (eGFR) rather than ageing per se. We sought to determine the impact of these 2 parameters, as well as sex and baseline body mass index (BMI), on the efficacy and safety of canagliflozin, a sodium glucose co-transporter 2 inhibitor, in people with type 2 diabetes.
Methods: Data were pooled from 6 randomized, double-blind, placebo-controlled studies (18 or 26 weeks; N=4053).
Objectives: To compare the efficacy and safety of canagliflozin, a sodium glucose co-transporter 2 inhibitor developed to treat type 2 diabetes mellitus (T2DM), in individuals younger than 75 and those aged 75 and older.
Design: Randomized Phase 3 studies.
Setting: International study centers.
The sodium glucose co-transporter 2 (SGLT2) inhibitor canagliflozin is a novel treatment option for adults with type 2 diabetes mellitus (T2DM). In patients with hyperglycemia, SGLT2 inhibition lowers plasma glucose levels by reducing the renal threshold for glucose (RTG ) and increasing urinary glucose excretion (UGE). Increased UGE is also associated with a mild osmotic diuresis and net caloric loss, which can lead to reductions in body weight and blood pressure (BP).

Methods: The CANagliflozin cardioVascular Assessment Study (CANVAS) is a double-blind, placebo-controlled cardiovascular outcomes study that randomized participants to placebo or canagliflozin 100 or 300 mg once daily in addition to routine therapy. Participants in the CANVAS trial are men and women aged ≥30 years with T2DM and a history or high risk of cardiovascular disease, and inadequate glycemic control (glycated hemoglobin [HbA1c] ≥7.
Objective: There are limited data about the effects of sodium-glucose cotransporter 2 inhibitors when used with insulin. We report the efficacy and safety of canagliflozin in patients with type 2 diabetes using insulin.
Research Design And Methods: The CANagliflozin CardioVascular Assessment Study is a double-blind, placebo-controlled study that randomized participants to placebo, canagliflozin 100 mg, or canagliflozin 300 mg once daily, added to a range of therapies.
Background: Canagliflozin is a sodium glucose co-transporter 2 inhibitor developed for the treatment of patients with type 2 diabetes mellitus (T2DM). The efficacy and safety of canagliflozin were evaluated in patients with T2DM <65 and ≥65 years of age.
Methods: Pooled data from 4 randomised, placebo-controlled, 26-week, Phase 3 studies (N = 2,313) evaluating canagliflozin 100 and 300 mg were analysed by age: <65 years (n = 1,868; mean age, 52.
Sodium glucose co-transporter 2 inhibition is a novel mode of treatment for type 2 diabetes mellitus (T2DM). The sodium glucose co-transporter 2 inhibitor canagliflozin lowered blood glucose, blood pressure, and body weight, with increased risk of urogenital infections in Phase 2 studies. Effects on macrovascular complications of diabetes remain to be determined.
