Background: This study aimed to investigate the preventive effects of tofogliflozin, a selective sodium-glucose cotransporter 2 (SGLT2) inhibitor, on atherosclerosis progression in type 2 diabetes (T2DM) patients without apparent cardiovascular disease (CVD) by monitoring carotid intima-media thickness (IMT).

Methods: This prospective, randomized, open-label, blinded-endpoint, multicenter, parallel-group, comparative study included 340 subjects with T2DM but no history of apparent CVD recruited at 24 clinical units. Subjects were randomly allocated to either the tofogliflozin treatment group (n=169) or conventional treatment group using drugs other than SGLT2 inhibitors (n=171). Primary outcomes were changes in mean and maximum common carotid IMT measured by echography during a 104-week treatment period.

Findings: Although the mean IMT of the common carotid artery (mean-IMT-CCA), along with the right and left maximum IMT of the CCA (max-IMT-CCA), statistically significantly declined in both the tofogliflozin (-0.132 mm, SE 0.007; -0.163 mm, SE 0.013; -0.170 mm, SE 0.020; respectively) and the control group (-0·140 mm, SE 0·006; -0·190 mm, SE 0·012; -0·190 mm, SE 0·020; respectively), no significant difference was observed between the two groups. Relative to the control treatment effects, tofogliflozin statistically significantly reduced the HbA1c, blood glucose level, body weight/body mass index, abdominal circumference, and systolic blood pressure, and statistically significantly increased the HDL-C.

Interpretation: A tofogliflozin treatment regimen of 104 weeks was not associated with improved inhibition of carotid wall thickening in T2DM patients without apparent CVD, as compared to the effect of the control treatment.
