Sodium-glucose cotransporter 2 inhibitors compared with other glucose-lowering drugs in Japan: Subanalyses of the CVD-REAL 2 Study.

ABSTRACT: There are limited data on cardiovascular efficacy and safety of type 2 diabetes therapies in Japan, where treatments are characterized by lower metformin use and higher dipeptidyl peptidase-4 inhibitor (DPP4i) use versus other countries. We investigated the cardiovascular outcomes in Japanese patients with type 2 diabetes initiating sodium-glucose cotransporter 2 inhibitors (SGLT2i) matched 1:1 to patients initiating other glucose-lowering drugs (33,890 patients/group) or DPP4i (9,876 patients/group). SGLT2i initiation was associated with lower risks (hazard ratio of in-hospital death [death] 0.56, 95% confidence interval [CI] 0.47-0.67; hospitalization for heart failure 0.75, 95% CI 0.64-0.89; composite of hospitalization for heart failure or death 0.65, 95% CI 0.58-0.74 and stroke 0.66, 95% CI 0.52-0.84 versus other glucose-lowering drugs and lower risks of death 0.52, 95% CI 0.36-0.73) and composite of hospitalization for heart failure or death (0.65, 95% CI 0.51-0.83) versus DPP4i. In conclusion, SGLT2i initiators had lower risks of cardiovascular events versus other glucose-lowering drug initiators and, uniquely, versus DPP4i initiators in Japanese real-world practice.

Project description:BACKGROUND:Reduction in cardiovascular death and hospitalization for heart failure (HHF) was recently reported with the sodium-glucose cotransporter-2 inhibitor (SGLT-2i) empagliflozin in patients with type 2 diabetes mellitus who have atherosclerotic cardiovascular disease. We compared HHF and death in patients newly initiated on any SGLT-2i versus other glucose-lowering drugs in 6 countries to determine if these benefits are seen in real-world practice and across SGLT-2i class. METHODS:Data were collected via medical claims, primary care/hospital records, and national registries from the United States, Norway, Denmark, Sweden, Germany, and the United Kingdom. Propensity score for SGLT-2i initiation was used to match treatment groups. Hazard ratios for HHF, death, and their combination were estimated by country and pooled to determine weighted effect size. Death data were not available for Germany. RESULTS:After propensity matching, there were 309?056 patients newly initiated on either SGLT-2i or other glucose-lowering drugs (154?528 patients in each treatment group). Canagliflozin, dapagliflozin, and empagliflozin accounted for 53%, 42%, and 5% of the total exposure time in the SGLT-2i class, respectively. Baseline characteristics were balanced between the 2 groups. There were 961 HHF cases during 190?164 person-years follow-up (incidence rate, 0.51/100 person-years). Of 215?622 patients in the United States, Norway, Denmark, Sweden, and the United Kingdom, death occurred in 1334 (incidence rate, 0.87/100 person-years), and HHF or death in 1983 (incidence rate, 1.38/100 person-years). Use of SGLT-2i, versus other glucose-lowering drugs, was associated with lower rates of HHF (hazard ratio, 0.61; 95% confidence interval, 0.51-0.73; P<0.001); death (hazard ratio, 0.49; 95% confidence interval, 0.41-0.57; P<0.001); and HHF or death (hazard ratio, 0.54; 95% confidence interval, 0.48-0.60; P<0.001) with no significant heterogeneity by country. CONCLUSIONS:In this large multinational study, treatment with SGLT-2i versus other glucose-lowering drugs was associated with a lower risk of HHF and death, suggesting that the benefits seen with empagliflozin in a randomized trial may be a class effect applicable to a broad population of patients with type 2 diabetes mellitus in real-world practice.
