DWP16001 is a novel sodium-glucose cotransporter-2 (SGLT2) inhibitor under development for the treatment of type 2 diabetes mellitus. This study was conducted to evaluate the pharmacokinetics (PK), pharmacodynamics (PD), and safety of DWP16001 after single and multiple doses in healthy subjects. A randomized, double-blind, placebo- and active-controlled, single- and multiple-dose study was conducted. Twelve subjects in each dose group received a single dose (0.2, 0.5, 1.0, 2.0, or 5.0 mg) or multiple doses (0.1, 0.3, 0.5, 1.0, or 2.0 mg once daily for 15 consecutive days) of DWP16001, dapagliflozin 10 mg, or placebo, in a ratio of 8:2:2. Serial blood samples and interval urine samples were collected for PK and PD analyses. Safety and tolerability were assessed throughout the study period. A dose-dependent increase in urinary glucose excretion (UGE) was observed after a single dose, and the steady-state UGE was 50–60 g/day after multiple doses in the dose range of 0.3 – 2.0 mg. DWP16001 was rapidly absorbed with the time to peak plasma concentration of 1.0 – 3.0 hours, and eliminated with a mean elimination half-life of 13 - 29 hours. The systemic exposure of DWP16001 increased proportionally with the dose after multiple administrations in the range of 0.1 – 2.0 mg. DWP16001 was well tolerated in all dose groups. DWP16001 caused glucosuria in a dose-dependent manner, and systemic exposure was observed after multiple doses. DWP16001 was well tolerated up to 5.0 mg after a single oral dose and up to 2.0 mg after multiple oral administration |
