Clinical outcomes with canagliflozin according to baseline body mass index: results from post hoc analyses of the CANVAS Program.

ABSTRACT:

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).

Materials and methods

The CANVAS Program randomized 10?142 participants with type 2 diabetes to canagliflozin or placebo. These analyses tested the consistency of canagliflozin treatment effects across BMI levels for cardiovascular, renal, safety and body weight outcomes in three groups defined by baseline BMI: <25, 25-<30 and??30?kg/m² .

Results

In total, 10?128 participants with baseline BMI measurements were included. There were 966 participants with BMI <25?kg/m² , 3153 with BMI 25-<30?kg/m² and 6009 with BMI ?30?kg/m² . Mean percent body weight reduction with canagliflozin compared with placebo was greater at 12?months [-2.77%? (95% confidence interval (CI): -2.95, -2.59)] than at 3?months [-1.72%? (95% CI: -1.83, -1.62)]. The hazard ratios (HRs) for canagliflozin compared with placebo control for the composite outcome of cardiovascular death, non-fatal myocardial infarction or non-fatal stroke were 1.03 (95% CI: 0.66, 1.59) in participants with BMI <25?kg/m² , 0.97 (0.76, 1.23) with BMI 25-<30?kg/m² and 0.79 (0.67, 0.93) with BMI ?30?kg/m² (P for heterogeneity = 0.55). The effects of canagliflozin on each component of the composite were also similar across BMI subgroups, as were effects on heart failure and renal outcomes (P for heterogeneity ?0.19). The effects on safety outcomes were also broadly similar.

Conclusions

Canagliflozin improved cardiovascular and renal outcomes consistently across patients with a broad range of BMI levels.

Project description:AimsThe CANVAS Program identified the effect of canagliflozin on major adverse cardiovascular events (MACE) differed according to whether participants were using diuretics at study commencement. We sought to further evaluate this finding related to baseline differences, treatment effects, safety, and risk factor changes.Methods and resultsThe CANVAS Program enrolled 10 142 participants with type 2 diabetes mellitus and high cardiovascular risk. Participants were randomized to canagliflozin or placebo and followed for a mean of 188 weeks. The primary outcome was major cardiovascular events, a composite of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke. Secondary outcomes included multiple cardiovascular, renal, and safety events. In this post hoc subgroup analysis, participants were categorized according to baseline use of any diuretic. The effect on outcomes was compared using Cox proportional hazards models, while risk factor changes were compared using mixed-effect models. At baseline, 4490 (44.3%) participants were using a diuretic. Compared with those not using a diuretic, participants using a diuretic were more likely to be older (mean age ± standard deviation, 64.3 ± 8.0 vs. 62.5 ± 8.3), be female (38.9% vs. 33.4%), and have heart failure (19.6% vs. 10.3%) (all Pdifference < 0.0001). The effect of canagliflozin on major cardiovascular events was greater for those using diuretic at baseline than for those who were not [adjusted hazard ratio 0.65 (95% confidence interval 0.54-0.78) vs. adjusted hazard ratio 1.13 (95% confidence interval 0.93-1.36), Pheterogeneity < 0.0001]. Changes in most risk factors, including blood pressure, body weight, and urine albumin-to-creatinine ratio, were similar between groups (all Pdifference > 0.11), although the effect of canagliflozin on haemoglobin A1c reduction was slightly weaker in participants using compared with not using diuretics at baseline (-0.52% vs. -0.64%, Pheterogeneity = 0.0007). Overall serious adverse events and key safety outcomes, including adverse renal events, were also similar (all Pheterogeneity > 0.07).ConclusionsParticipants on baseline diuretics derived a greater benefit for major cardiovascular events from canagliflozin, which was not fully explained by differences in participant characteristics nor risk factor changes.

Project description:BACKGROUND:Canagliflozin is a sodium glucose cotransporter 2 inhibitor that significantly reduces the composite of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke in patients with type 2 diabetes mellitus and elevated cardiovascular risk. The comparative effects among participants with and without a history of cardiovascular disease (secondary versus primary prevention) were prespecified for evaluation. METHODS:The CANVAS Program (Canagliflozin Cardiovascular Assessment Study) randomly assigned 10?142 participants with type 2 diabetes mellitus to canagliflozin or placebo. The primary prevention cohort comprised individuals ?50 years of age with ?2 risk factors for cardiovascular events but with no prior cardiovascular event, and the secondary prevention cohort comprised individuals ?30 years of age with a prior cardiovascular event. The primary end point was a composite of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke. Secondary outcomes included heart failure hospitalization and a renal composite (40% reduction in estimated glomerular filtration rate, renal replacement therapy, or renal death). RESULTS:Primary prevention participants (N=3486; 34%) were younger (63 versus 64 years of age), were more often female (45% versus 31%), and had a longer duration of diabetes mellitus (14 versus 13 years) compared with secondary prevention participants (N=6656; 66%). The primary end point event rate was higher in the secondary prevention group compared with the primary prevention group (36.9 versus 15.7/1000 patient-years, P<0.001). In the total cohort, the primary end point was reduced with canagliflozin compared with placebo (26.9 versus 31.5/1000 patient-years; hazard ratio [HR], 0.86; 95% confidence interval [CI], 0.75-0.97; P<0.001 for noninferiority, P=0.02 for superiority) with no statistical evidence of heterogeneity (interaction P value=0.18) between the primary (HR, 0.98; 95% CI, 0.74-1.30) and secondary prevention (HR, 0.82; 95% CI, 0.72-0.95) cohorts. Renal outcomes (HR, 0.59; 95% CI, 0.44-0.79 versus HR, 0.63; 95% CI, 0.39-1.02; interaction P value=0.73) and heart failure hospitalization (HR, 0.68; 95% CI, 0.51-0.90 versus HR, 0.64; 95% CI, 0.35-1.15; interaction P value=0.91) were similarly reduced in the secondary and primary prevention cohorts, respectively. Lower extremity amputations were similarly increased in the secondary and primary prevention cohorts (HR, 2.07; 95% CI, 1.43-3.00 versus HR, 1.52; 95% CI, 0.70-3.29; interaction P value=0.63). CONCLUSIONS:Patients with type 2 diabetes mellitus and prior cardiovascular events had higher rates of cardiovascular outcomes compared with the primary prevention patients. Canagliflozin reduced cardiovascular and renal outcomes with no statistical evidence of heterogeneity of the treatment effect across the primary and secondary prevention groups. Additional studies will provide further insights into the effects of canagliflozin in these patient populations. CLINICAL TRIAL REGISTRATION:URL: https://www.clinicaltrials.gov.

Project description:BACKGROUND:Canagliflozin is approved for glucose lowering in type 2 diabetes and confers cardiovascular and renal benefits. We sought to assess whether it had benefits in people with chronic kidney disease, including those with an estimated glomerular filtration rate (eGFR) between 30 and 45 mL/min/1.73 m2 in whom the drug is not currently approved for use. METHODS:The CANVAS Program randomized 10 142 participants with type 2 diabetes and eGFR >30 mL/min/1.73 m2 to canagliflozin or placebo. The primary outcome was a composite of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke, with other cardiovascular, renal, and safety outcomes. This secondary analysis describes outcomes in participants with and without chronic kidney disease, defined as eGFR <60 and ?60 mL/min/1.73 m2, and according to baseline kidney function (eGFR <45, 45 to <60, 60 to <90, and ?90 mL/min/1.73 m2). RESULTS:At baseline, 2039 (20.1%) participants had an eGFR <60 mL/min/1.73 m2, 71.6% of whom had a history of cardiovascular disease. The effect of canagliflozin on the primary outcome was similar in people with chronic kidney disease (hazard ratio, 0.70; 95% CI, 0.55-0.90) and those with preserved kidney function (hazard ratio, 0.92; 95% CI, 0.79-1.07; P heterogeneity = 0.08). Relative effects on most cardiovascular and renal outcomes were similar across eGFR subgroups, with possible heterogeneity suggested only for the outcome of fatal/nonfatal stroke ( P heterogeneity = 0.01), as were results for almost all safety outcomes. CONCLUSIONS:The effects of canagliflozin on cardiovascular and renal outcomes were not modified by baseline level of kidney function in people with type 2 diabetes and a history or high risk of cardiovascular disease down to eGFR levels of 30 mL/min/1.73 m2. Reassessing current limitations on the use of canagliflozin in chronic kidney disease may allow additional individuals to benefit from this therapy.

Project description:IntroductionLong-acting muscarinic antagonists (LAMAs), long-acting β2-agonists (LABAs), inhaled corticosteroids (ICS), and their combinations, are recommended for the treatment of chronic obstructive pulmonary disease (COPD). This study aimed to determine whether the safety and efficacy of aclidinium bromide differs by baseline maintenance LABA and ICS therapies.MethodsASCENT-COPD was a phase 4, multicenter, double-blind, randomized, placebo-controlled, parallel-group study of patients with moderate-to-very severe COPD and increased cardiovascular risk. Patients were randomized 1:1 to receive aclidinium 400 μg or placebo twice daily, via a multidose dry-powder inhaler for up to 3 years. Outcomes included time to first major adverse cardiovascular events (MACE), all-cause mortality, change from baseline in trough forced expiratory volume in 1 s (FEV1), and COPD assessment test (CAT) total score over 3 years, and annual moderate-to-severe COPD exacerbation rate in patients receiving aclidinium or placebo with maintenance LABA monotherapy, ICS monotherapy, LABA + ICS (fixed/free), or no maintenance therapy (neither LABA nor ICS) at baseline.ResultsA total of 3589 patients were included (LABA, n = 227; ICS, n = 290; LABA + ICS, n = 2058; no maintenance, n = 1130). Aclidinium did not increase the risk of MACE or all-cause mortality versus placebo, regardless of baseline maintenance treatment. Reductions in moderate-to-severe exacerbation rates were observed with aclidinium versus placebo in all subgroups [LABA 43% (P = 0.046); ICS 25% (P = 0.202); LABA + ICS 22% (P = 0.003); no maintenance 18% (P = 0.130)]. Aclidinium improved morning trough FEV1 irrespective of baseline therapy and CAT total scores, except for LABA and ICS subgroups, versus placebo at several time points.ConclusionIn patients with moderate-to-severe COPD and CV risk factors, the addition of aclidinium to maintenance therapy with LABA or LABA + ICS provided further benefit.Trial registrationClinicalTrials.gov identifier NCT01966107.

Project description:Aims/hypothesisAn increased risk of fracture with canagliflozin vs placebo was reported from the CANagliflozin cardioVascular Assessment Study (CANVAS) Program, with heterogeneity of findings identified between the two trials that comprise the CANVAS Program, CANVAS and CANVAS-R. The objective of these analyses was to identify reasons for the possibly different effects on fracture observed between CANVAS and CANVAS-R.MethodsThis study was an analysis of two highly similar trials, CANVAS and CANVAS-R, conducted in 10,142 individuals with type 2 diabetes and history or high risk of cardiovascular disease who received canagliflozin (pooled 100/300 mg once daily) or placebo. Outcomes assessed in this analysis were effects on adjudicated fractures overall and by type, location, association with a fall, dose and follow-up time.ResultsA total of 496 participants recorded ≥1 fracture event during follow-up (15.40 vs 11.93 per 1000 patient-years with canagliflozin vs placebo; HR 1.26 [95% CI 1.04, 1.52]). There was significant heterogeneity in the effects on fracture (p = 0.005) between CANVAS (n = 4330: HR 1.55 [95% CI 1.21, 1.97]) and CANVAS-R (n = 5812: HR 0.86 [95% CI 0.62, 1.19]). The between-study heterogeneity in fracture risk was not clearly explained by differences in baseline characteristics, interactions of randomised treatment with participant characteristics, dose effects, duration of follow-up, metabolic effects, adverse events related to falls or adverse events possibly causing falls.Conclusions/interpretationThere was no evidence to explain clearly the fracture risk observed in the CANVAS Program or the heterogeneity in fracture risk between the two studies. The recently reported null result for fracture in the Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation (CREDENCE) trial suggests that the observed association in CANVAS is likely to be a chance finding, although an unidentified fall-related mechanism remains a possibility.Trial registrationClinicalTrials.gov NCT01032629, NCT01989754.
