Abstract

AIMS:

To compare the sodium-glucose-cotransporter-2 (SGLT-2) inhibitor dapagliflozin with dipeptidyl peptidase-4 (DPP-4) inhibitors with regard to risk associations with major adverse cardiovascular (CV) events (MACE; non-fatal myocardial infarction, non-fatal stroke or cardiovascular mortality), hospitalization for heart failure (HHF), atrial fibrillation and severe hypoglycaemia in patients with type 2 diabetes (T2D) in a real-world setting.

METHODS:

All patients with T2D prescribed glucose-lowering drugs (GLDs) during 2012 to 2015 were identified in nationwide registries in Denmark, Norway and Sweden. Patients were divided into two groups: new users of dapagliflozin and new users of DPP-4 inhibitors, matched 1:3 by propensity score, calculated by patient characteristics, comorbidities and drug treatment. Cox survival models were used to estimate hazard ratio (HR) per country separately, and a weighted average was calculated.

RESULTS:

After matching, a total of 40 908 patients with T2D were identified as new users of dapagliflozin (n = 10 227) or a DPP-4 inhibitor (n = 30 681). The groups were well balanced at baseline; their mean age was 61 years and 23% had CV disease. The mean follow-up time was 0.95 years, with a total of 38 760 patient-years. Dapagliflozin was associated with a lower risk of MACE, HHF and all-cause mortality compared with DPP-4 inhibitors: HRs 0.79 (95% confidence interval [CI] 0.67-0.94), 0.62 (95% CI 0.50-0.77), and 0.59 (95% CI 0.49-0.72), respectively. Numerically lower, but non-significant HRs were observed for myocardial infarction (0.91 [95% CI 0.72-1.16]), stroke (0.79 [95% CI 0.61-1.03]) and CV mortality (0.76 [95% CI 0.53-1.08]) Neutral associations with atrial fibrillation and severe hypoglycaemia were observed.

CONCLUSIONS:

Dapagliflozin was associated with lower risks of CV events and all-cause mortality compared with DPP-4 inhibitors in a real-world clinical setting and a broad T2D population.
