Canagliflozin Cardiovascular Assessment Study - CANVAS
Contribution To Literature:
The CANVAS trial showed that canagliflozin was superior at preventing cardiovascular events.
The goal of the trial was to evaluate the sodium-glucose cotransporter 2 inhibitor canagliflozin compared with placebo among patients with type 2 diabetes.
Patients with type 2 diabetes were randomized to canagliflozin (n = 5,795) versus placebo (n = 4,347). Patients in the canagliflozin arm received 300 mg daily or 100 mg daily.
- Patients with type 2 diabetes and high cardiovascular risk
- ≥30 years of age and history of symptomatic atherosclerotic cardiovascular disease, or
- ≥50 years of age and 2+ of the following: diabetes duration >10 years, systolic blood pressure >140 mm Hg on antihypertensive therapy, current smoking, albuminuria, or high-density lipoprotein cholesterol <38.7 mg/dl
- Total number of enrollees: 10,142
- Duration of follow-up: 188 weeks
- Mean patient age: 63 years
- Percentage female: 36%
- Percentage with diabetes: 100%
Other salient features/characteristics:
- Mean duration of diabetes: 13.5 years
- 65.6% of participants had history of cardiovascular disease
The primary outcome, incidence of cardiovascular death, myocardial infarction, or stroke, occurred in 26.9 participants per 1,000 patient-years of the canagliflozin group versus 31.5 participants per 1,000 patient-years of the placebo group (p = 0.02 for superiority, p < 0.001 for noninferiority).
- Amputation: 6.3 participants per 1,000 patient-years versus 3.4 participants per 1,000 patient-years (p < 0.05)
- Progression of albuminuria: 89.4 participants per 1,000 patient-years versus 128.7 participants per 1,000 patient-years (p < 0.05)
Among patients with type 2 diabetes, canagliflozin was beneficial. Canagliflozin compared with placebo was associated with a lower frequency of adverse cardiovascular events. Canagliflozin was also associated with a lower rate of progression of albuminuria; however, amputation occurred more frequently.
