Effect of Dapagliflozine on Systemic and Renal Endothelial Function

July 15, 2015 updated by: Min Kyong Moon, Seoul National University Hospital

Effect of Sodium Glucose Co-transporter 2 (SGLT2) Inhibitor on Systemic and Renal Endothelial Function in Patients With Type 2 Diabetes Mellitus Without History of Coronary Artery Disease (SOCCER Trial)

This is a phase 4, single center, randomized, open-labeled, cross-over design study. The primary objective of the study is to compare effect of dapagliflozine and metformin on endothelial function.

Subjects are randomized to initial metformin or initial dapagliflozin group and maintained initial treatment for 8 weeks. During that period, dose of dapagliflozin is maintained 10mg/day and metformin can be titrated upto 2000 mg/day. After 1 weeks of washout period, 8 weeks' cross-over is followed.
