- Background: Canagliflozin is a sodium glucose cotransporter 2 inhibitor that reduces the risk of cardiovascular events. We report the effects on heart failure (HF) and cardiovascular death overall, in those with and without a baseline history of HF, and in other participant subgroups. Methods: The CANVAS Program (Canagliflozin Cardiovascular Assessment Study) enrolled 10142 participants with type 2 diabetes mellitus and high cardiovascular risk. Participants were randomly assigned to canagliflozin or placebo and followed for a mean of 188 weeks. The primary end point for these analyses was adjudicated cardiovascular death or hospitalized HF. Results: Participants with a history of HF at baseline (14.4%) were more frequently women, white, and hypertensive and had a history of prior cardiovascular disease (all Pamp;lt;0.001). Greater proportions of these patients were using therapies such as blockers of the renin angiotensin aldosterone system, diuretics, and -blockers at baseline (all Pamp;lt;0.001). Overall, cardiovascular death or hospitalized HF was reduced in those treated with canagliflozin compared with placebo (16.3 versus 20.8 per 1000 patient-years; hazard ratio [HR], 0.78; 95% confidence interval [CI], 0.67-0.91), as was fatal or hospitalized HF (HR, 0.70; 95% CI, 0.55-0.89) and hospitalized HF alone (HR, 0.67; 95% CI, 0.52-0.87). The benefit on cardiovascular death or hospitalized HF may be greater in patients with a prior history of HF (HR, 0.61; 95% CI, 0.46-0.80) compared with those without HF at baseline (HR, 0.87; 95% CI, 0.72-1.06; P interaction =0.021). The effects of canagliflozin compared with placebo on other cardiovascular outcomes and key safety outcomes were similar in participants with and without HF at baseline (all interaction P values amp;gt;0.130), except for a possibly reduced absolute rate of events attributable to osmotic diuresis among those with a prior history of HF (P=0.03). Conclusions: In patients with type 2 diabetes mellitus and an elevated risk of cardiovascular disease, canagliflozin reduced the risk of cardiovascular death or hospitalized HF across a broad range of different patient subgroups. Benefits may be greater in those with a history of HF at baseline. Clinical Trial Registration: URL: https://www.clinicaltrials.gov. Unique identifiers: NCT01032629 and NCT01989754.

- Aim: Sodium glucose co-transporter 2 (SGLT2) inhibitors appear to protect against increased risks of cardiovascular and kidney disease in patients with type 2 diabetes but also cause some harms. Whether effects are comparable across drug class or specific to individual compounds is unclear. This meta-analysis assessed the class and individual compound effects of SGLT2 inhibition versus control on cardiovascular events, death, kidney disease and safety outcomes in patients with type 2 diabetes. Methods: MEDLINE, EMBASE, the Cochrane Library and regulatory databases were systematically searched for data from randomized clinical trials that included reporting of cardiovascular events, deaths or safety outcomes. We used fixed effects models and inverse variance weighting to calculate relative risks with the 95% confidence intervals. Results: The analyses included data from 82 trials, four overviews and six regulatory reports and there were 1,968 major cardiovascular events identified for analysis. Patients randomly assigned to SGLT2 had lower risks of major cardiovascular events (RR 0.85, 95% CI 0.77-0.93), heart failure (RR 0.67, 95% CI 0.55-0.80), all-cause death (RR 0.79, 95% CI 0.70-0.88) and serious decline in kidney function (RR 0.59, 0.49-0.71). Significant adverse effects were observed for genital infections (RR 3.06, 95% CI 2.73-4.43), volume depletion events (RR 1.24, 95% CI 1.07-1.43) and amputation (RR 1.44 95% CI 1.13-1.83). There was a high likelihood of differences in the associations of the individual compounds with cardiovascular death, hypoglycaemia and amputation (all I-2 amp;gt; 80%) and a moderate likelihood of differences in the associations with non-fatal stroke, all-cause death, urinary tract infection and fracture (all I-2 amp;gt; 30%). Conclusion: There are strong overall associations of SGLT2 inhibition with protection against major cardiovascular events, heart failure, serious decline in kidney function and all-cause death. SGLT2 inhibitors were also associated with infections, volume depletion effects and amputation. Some associations appear to differ between compounds. (C) 2018 Elsevier B.V. All rights reserved.

- BackgroundWe aimed to investigate whether the benefits of blood pressure-lowering drugs are proportional to baseline cardiovascular risk, to establish whether absolute risk could be used to inform treatment decisions for blood pressure-lowering therapy, as is recommended for lipid-lowering therapy. MethodsThis meta-analysis included individual participant data from trials that randomly assigned patients to either blood pressure-lowering drugs or placebo, or to more intensive or less intensive blood pressure-lowering regimens. The primary outcome was total major cardiovascular events, consisting of stroke, heart attack, heart failure, or cardiovascular death. Participants were separated into four categories of baseline 5-year major cardiovascular risk using a risk prediction equation developed from the placebo groups of the included trials (<11%, 11-15%, 15-21%, >21%).Findings11 trials and 26 randomised groups met the inclusion criteria, and included 67 475 individuals, of whom 51 917 had available data for the calculation of the risk equations. 4167 (8%) had a cardiovascular event during a median of 4.0 years (IQR 3.4-4.4) of follow-up. The mean estimated baseline levels of 5-year cardiovascular risk for each of the four risk groups were 6 0% (SD 2.0), 12.1% (1.5), 17.7% (1.7), and 26.8% (5.4). In each consecutive higher risk group, blood pressure-lowering treatment reduced the risk of cardiovascular events relatively by 18% (95% CI 7-27), 15% (4-25), 13% (2-22), and 15% (5-24), respectively (p=0.30 for trend). However, in absolute terms, treating 1000 patients in each group with blood pressure-lowering treatment for 5 years would prevent 14 (95% CI 8-21), 20 (8-31), 24 (8-40), and 38 (16-61) cardiovascular events, respectively (p=0.04 for trend). Interpretation Lowering blood pressure provides similar relative protection at all levels of baseline cardiovascular risk, but progressively greater absolute risk reductions as baseline risk increases. These results support the use of predicted baseline cardiovascular disease risk equations to inform blood pressure-lowering treatment decisions.

- Background Sodium glucose co-transporter-2 (SGLT2) inhibitors reduce the risk of kidney and heart failure events independent of glycemic effects. We assessed whether initiation of the SGLT2 inhibitor canagliflozin guided by multivariable predicted risk based on clinical characteristics and novel biomarkers is more efficient to prevent clinical outcomes compared to a strategy guided by HbA1c or urinary-albumin-creatinine ratio (UACR) alone. Methods We performed a post-hoc analysis of the CANVAS trial including 3713 patients with available biomarker measurements. We compared the number of composite kidney (defined as a sustained 40% decline in eGFR, chronic dialysis, kidney transplantation, or kidney death) and composite heart failure outcomes (defined as heart failure hospitalization or cardiovascular (CV) death) prevented per 1000 patients treated for 5 years when canagliflozin was initiated in patients according to HbA1c >= 7.5%, UACR, or multivariable risk models consisting of: (1) clinical characteristics, or (2) clinical characteristics and novel biomarkers. Differences in the rates of events prevented between strategies were tested by Chi(2)-statistic. Results After a median follow-up of 6.1 years, 144 kidney events were recorded. The final clinical model included age, previous history of CV disease, systolic blood pressure, UACR, hemoglobin, body weight, albumin, estimated glomerular filtration rate, and randomized treatment assignment. The combined biomarkers model included all clinical characteristics, tumor necrosis factor receptor-1, kidney injury molecule-1, matrix metallopeptidase-7 and interleukin-6. Treating all patients with HbA1c >= 7.5% (n = 2809) would prevent 33.0 (95% CI 18.8 to 43.3 ) kidney events at a rate of 9.6 (95% CI 5.5 to 12.6) events prevented per 1000 patients treated for 5 years. The corresponding rates were 5.8 (95% CI 3.4 to 7.9), 16.6 (95% CI 9.5 to 22.0) (P < 0.001 versus HbA1c or UACR approach), and 17.5 (95% CI 10.0 to 23.0) (P < 0.001 versus HbA1c or UACR approach; P = 0.54 versus clinical model). Findings were similar for the heart failure outcome. Conclusion Initiation of canagliflozin based on an estimated risk-based approach prevented more kidney and heart failure outcomes compared to a strategy based on HbA1c or UACR alone. There was no apparent gain from adding novel biomarkers to the clinical risk model. These findings support the use of risk-based assessment using clinical markers to guide initiation of SGLT2 inhibitors in patients with type 2 diabetes.

- Background In patients with type 2 diabetes, sodium-glucose cotransporter-2 (SGLT2) inhibitors are known to reduce glucose concentrations, blood pressure, and weight, but to increase LDL cholesterol and the incidence of urogenital infections. Protection against cardiovascular events has also been reported, as have possible increased risks of adverse outcomes such as ketoacidosis and bone fracture. We aimed to establish the effects of SGLT2 inhibitors on cardiovascular events, death, and safety outcomes in adults with type 2 diabetes, both overall and separately for individual drugs. Methods In this systematic review and meta-analysis, we searched MEDLINE, Embase, the Cochrane Library, and websites of US, European, and Japanese regulatory authorities from Jan 1, 1950, to Sept 30, 2015, for data from prospective randomised controlled trials assessing the effects of SGLT2 treatment compared with controls. We excluded duplicate reports, trials of compound drugs, trials that lasted 7 days or fewer, trials that did not report on outcomes of interest, and articles that presented pooled trial data for which the individual trials could not be identified. We extracted data in duplicate using a standardised approach. The primary outcome was major adverse cardiovascular events. Secondary outcomes were cardiovascular death, non-fatal myocardial infarction, non-fatal stroke, admission to hospital for unstable angina, heart failure, and all-cause mortality. We estimated summary relative risks with fixed-effects meta-analysis, with the I-2 statistic used to estimate heterogeneity of results beyond chance. Findings The analyses included data from six regulatory submissions (37 525 participants) and 57 published trials (33 385 participants), which provided data for seven different SGLT2 inhibitors. SGLT2 inhibitors protected against the risk of major adverse cardiovascular events (relative risk 0.84 [95% CI 0.75-0.95]; p=0.006), cardiovascular death (0.63 [0.51-0.77]; p<0.0001), heart failure (0.65 [0.50-0.85]; p=0.002), and death from any cause (0.71 [0.61-0.83]; p<0.0001). No clear effect was apparent for non-fatal myocardial infarction (0.88 [0.72-1.07]; p=0.18) or angina (0.95 [0.73-1.23]; p=0.70), but we noted an adverse effect for non-fatal stroke (1.30 [1.00-1.68]; p=0.049). We noted no clear evidence that the individual drugs had different effects on cardiovascular outcomes or death (all I I-2 < 43%). Safety analyses showed consistent increased risks of genital infections (regulatory submissions 4.75 [4.00-5.63]; scientific reports 2.88 [2.48-3.34]), but findings for some safety outcomes varied depending on whether anlayses were based on data extracted from regulatory submissions or trials reported in the scientific literature. Interpretation These data suggest net protection of SGLT2 inhibitors against cardiovascular outcomes and death. The efficacy results were driven by findings for empagliflozin (the only SGLT2 inhibitor for which data from a dedicated long-term cardiovascular safety trial have been reported), although results for the other drugs in the class were not clearly different. Adverse events were more difficult to quantify than was efficacy, with the effects of individual drugs in the class seeming to differ for some safety outcomes. Results from ongoing studies will be crucial to substantiate these findings across the drug class, but the available data provide a strong rationale to expect benefit from use of SGLT2 inhibitors in patients with type 2 diabetes at high risk of cardiovascular events.

- Background and Purpose-This study reports the detailed effects of canagliflozin on stroke, stroke subtypes, and vascular outcomes in participants with and without cerebrovascular disease (stroke or transient ischemic attack) at baseline from the CANVAS (Canagliflozin Cardiovascular Assessment Study) Program. Methods-The CANVAS Program, comprising 2 similarly designed and conducted clinical trials, randomly assigned 10 142 participants with type 2 diabetes mellitus and high cardiovascular risk to canagliflozin or placebo. Its primary outcome was a composite of major adverse cardiovascular events. The main outcome of interest for this report was fatal or nonfatal stroke. Additional exploratory outcomes were stroke subtypes and other vascular outcomes defined according to standard criteria. Results-There were 1 958 (19%) participants with prior stroke or transient ischemic attack at baseline. These individuals were older, more frequently women, and had higher rates of heart failure, atrial fibrillation, and microvascular disease (all Pamp;lt;0.001) compared with those without such a history. There were 309 participants with stroke events during followup (123 had prior stroke or transient ischemic attack at baseline and 186 did not), at a rate of 7.93/1000 patient-years among those assigned canagliflozin and 9.62/1000 patient-years among placebo (hazard ratio, 0.87; 95% CI, 0.691.09). Analysis of stroke subtypes found no effect on ischemic stroke (n=253, hazard ratio, 0.95; 95% CI, 0.74-1.22), a significant reduction for hemorrhagic stroke (n=30, hazard ratio, 0.43; 95% CI, 0.20-0.89) and no effect on undetermined stroke (n=29, hazard ratio, 1.04; 95% CI, 0.48-2.22). Effects on other cardiovascular outcomes were comparable among participants with and without stroke or transient ischemic attack at baseline. Conclusions-There were too few events in the CANVAS Program to separately define the effects of canagliflozin on stroke, but benefit is more likely than harm. The observed possible protective effect for hemorrhagic stroke was based on small numbers but warrants further investigation.
