Objective
Linagliptin, a dipeptidyl peptidase-4 inhibitor, demonstrated cardiovascular and renal safety in type 2 diabetes mellitus (T2DM) patients with established cardiovascular disease (CVD) with albuminuria and/or kidney disease in the multinational CARMELINA® trial. We investigated the effects of linagliptin in Asian patients in CARMELINA®.
Methods
T2DM patients with HbA1c 6.5–10.0% and established CVD with urinary albumin-to-creatinine ratio (UACR) > 30 mg/g, and/or prevalent kidney disease (estimated glomerular filtration rate [eGFR] 15–< 45 ml/min/1.73 m2 or ≥ 45–75 with UACR > 200 mg/g), were randomized to linagliptin or placebo added to usual care. The primary endpoint was time to first occurrence of cardiovascular death, non-fatal myocardial infarction, or non-fatal stroke (3-point MACE).
Results
Of the 6979 patients, 555 (8.0%) were Asians living in Asia. During a median follow-up of 2.2 years, 3-point MACE occurred in 29/272 (10.7%) and 33/283 (11.7%) of linagliptin and placebo patients, respectively (hazard ratio [HR] 0.90; 95% confidence interval [CI] 0.55–1.48), consistent with the overall population (HR 1.02; 95% CI 0.89–1.17; P value for treatment-by-region interaction: 0.3349). Similar neutrality in Asian patients was seen for other cardiorenal events including the secondary kidney endpoint of death from renal failure, progression to end-stage kidney disease, or ≥ 40% eGFR decrease (HR 0.96; 95% CI 0.58–1.59). Linagliptin was associated with a nominal decrease in the risk of hospitalization for heart failure (HR 0.47; 95% CI 0.24–0.95). Overall in Asian patients, linagliptin had an adverse event rate similar to placebo, consistent with the overall population.
Conclusions
Linagliptin showed cardiovascular and renal safety in Asian patients with T2DM and established CVD with albuminuria and/or kidney disease.
