Pharmacokinetic and Pharmacodynamic Drug-Drug Interactions between Evogliptin and Empagliflozin or Dapagliflozin in Healthy Male Volunteers.

Evogliptin is a novel dipeptidyl peptidase-4 inhibitor (DPP4i) for glycemic control in patients with type 2 diabetes mellitus(T2DM). This study evaluated the pharmacokinetic (PK) and pharmacodynamic (PD) interactions between evogliptin and sodium glucose cotransporter-2 inhibitors (SGLT2i) in healthy volunteers since combination therapy of DPP4i and SGLT2i has been considered as effective option for T2DM treatment. A randomized, open-label, multiple-dose, two-arm, three-period, three treatments, two-sequence crossover study was conducted in healthy Korean volunteers. In arm 1, subjects were administered 5 mg of evogliptin once daily for 7 days (EV), 25 mg of empagliflozin once daily for 5 days (EP), and the combination once daily for 5 days (EV+EP). In arm 2, subjects were administered 5 mg of evogliptin once daily for 7 days (EV), 10 mg of dapagliflozin once daily for 5 days (DP), and the combination once daily for 5 days (EV+DP). Serial blood samples were collected for PK analysis, and oral glucose tolerance tests were conducted for PD analysis. In each arm, a total of 18 subjects completed the study. All adverse events were mild with no serious adverse events. The geometric mean ratio and confidence interval of the main PK parameters (C and AUC ) between EV and either EP or DP alone were not significantly altered by co-administration. Administration of EV+EP or EV+DP did not result in significant PD changes, as determined by the glucose-lowering effect. Administration of EV+EP or EV+DP had no significant effects on the PK profiles of each drug. All treatments were well-tolerated.
