英文摘要

Background: Dapagliflozin, a selective, orally active, renal sodium glucose cotransporter 2 (SGLT2) 2 inhibitor, is under investigation as a treatment of type 2 diabetes mellitus (T2DM). Dapagliflozin reduces hyperglycemia by inhibiting renal glucose reabsorption and dose-dependently increasing urinary glucose excretion, independent of insulin secretion or action.

Objectives: These studies assessed the single- and multiple-dose pharmacokinetic and pharmaco dynamic properties of dapagliflozin and its major inactive metabolite, dapagliflozin 3-O-glucuronide (D3OG), in healthy subjects residing in China.

Methods: In 2 identically designed, open-label, single- and multiple-dose studies (n = 14 for both studies), healthy Chinese subjects were administered oral dapagliflozin 5 or 10 mg. In both studies, subjects received a single dose on day 1 (single-dose administration period) followed by 6 once-daily doses on days 5 to 10 (multiple-dose administration period). Pharmacokinetic parameters (plasma and urinary dapagliflozin and D3OG), pharmacodynamic response (urinary glucose excretion), and tolerability were assessed.

Results: Fourteen subjects completed the dapagliflozin 5-mg study, and 13 completed the dapagliflozin 10-mg study. Baseline characteristics were balanced across the two studies: 9 versus 10 men; mean age, 27.1 versus 28.9 years; mean weight, 62.8 versus 62.2 kg; and mean body mass index, 23.0 versus 22.2 kg/m(2) in the dapagliflozin 5- and 10-mg studies, respectively. In both doses, dapagliflozin was rapidly absorbed (T-max, <= 1.5 h), accumulation (defined as the geometric mean ratio of AUC(tau) at day 10 to AUC(tau) at day 1) after multiple dosing was minimal (<1.13 fold), and elimination half-life was 10 to 12 h. D3OG showed a slightly longer median T-max (<= 2 h) but a similar plasma concentration time profile and half-life compared with dapagliflozin. The majority of D3OG (up to 69.7% of the dapagliflozin dose) was excreted in urine, while <= 1.9% of dapagliflozin was excreted unchanged in urine. Over a 24-hour period and at steady state (day 10), urinary glucose excretion values were 28.1 and 41.1 g with dapagliflozin 5 and 10 mg, respectively. Dapagliflozin was generally well tolerated; one dapagliflozin 10 mg treated subject discontinued the study because of a serious adverse event (bronchitis) considered by the investigator as unrelated to dapagliflozin dosing.

Conclusions: Pharmacokinetic and pharmacodynamic characteristics following single- and multiple-dose dapagliflozin 5 and 10 mg oral administration in healthy Chinese subjects were as predicted from previous studies and were similar to findings observed in non-Chinese healthy subjects. Dapagliflozin dosing was well tolerated. The clinically recommended dapagliflozin dose of 10 mg once daily is expected to be appropriate in patients of Chinese ethnicity; results from an efficacy and tolerability study in Chinese patients with T2DM are awaited.
