Safety, tolerability, pharmacokinetics, and pharmacodynamics of multiple rising doses of empagliflozin in patients with type 2 diabetes mellitus.

ABSTRACT: INTRODUCTION:This study examined the safety, tolerability, pharmacokinetics, and pharmacodynamics of empagliflozin, a potent and highly selective sodium glucose cotransporter 2 (SGLT2) inhibitor, in patients with type 2 diabetes mellitus (T2DM). METHODS:A total of 48 patients with T2DM were randomized to receive one of four doses of empagliflozin (2.5, 10, 25, or 100 mg qd) or placebo over 8 days. In every dose group, nine patients received active drug and three received placebo. The primary endpoint was safety and tolerability. Pharmacokinetic and pharmacodynamic parameters were measured as secondary endpoints. RESULTS:Empagliflozin was rapidly absorbed, reaching peak levels 1.5-3.0 h after dosing and showed a biphasic decline. The mean terminal elimination half-life ranged from 10 to 19 h. Increases in exposure (area under the plasma concentration-time curve [AUC] and maximum concentration of analyte in plasma [C max]) were approximately proportional with dose. Empagliflozin increased the rate and total amount of glucose excreted in urine compared to placebo. After administration of a single dose of empagliflozin, cumulative amounts of glucose excreted in urine over 24 h ranged from 46.3 to 89.8 g, compared with 5.84 g with placebo. Similar results were seen after multiple doses. Fasting plasma glucose levels decreased by 17.2-25.8% with empagliflozin and by 12.7% with placebo. The frequency of adverse events was 33.3-66.7% with empagliflozin and 41.7% with placebo. There were no changes in urine volume or micturition frequency under the controlled study conditions. CONCLUSION:Overall, pharmacokinetic assessments demonstrated a dose-proportional increase in drug exposure and support once-daily dosing. Elevated urinary glucose excretion was observed with all doses. Multiple once-daily oral doses of empagliflozin (2.5-100 mg) reduced plasma glucose and were well tolerated in patients with T2DM.

Project description:IntroductionThe aim of this analysis was to characterize the safety and tolerability of empagliflozin in patients with type 2 diabetes mellitus (T2DM) who were randomized to empagliflozin (10/25 mg) or placebo in clinical trials.MethodsPooled data from 20 trials were analyzed for patients with T2DM treated with empagliflozin 10 mg (n = 4858), empagliflozin 25 mg (n = 5057), or placebo (n = 4904). The dataset comprised 15 randomized phase I-III trials, an extension trial and dose escalation studies. Adverse events (AEs) were assessed descriptively in participants who took ≥ 1 dose of study drug. AE incidence rates per 100 patient-years were calculated to adjust for differences in drug exposure between trials.ResultsTotal exposure was 16,480 and 7857 patient-years in the pooled empagliflozin 10/25 mg and placebo groups, respectively. The incidence of any AEs, AEs leading to treatment discontinuation, severe AEs, and serious AEs was similar across groups. The frequency of serious AEs requiring hospitalization was 18.6% for the empagliflozin 10/25 mg group and 21.3% for the placebo group. The empagliflozin 10/25 mg group was not associated with a higher rate of confirmed hypoglycemia versus placebo, except in patients co-administered insulin and/or a sulfonylurea (31.5% vs. 30.2%, respectively). The incidence of events consistent with urinary tract infections (UTI) was also similar for the empagliflozin 10/25 mg group versus placebo (9.27 vs. 9.70/100 patient-years, respectively). History of UTI was identified as a risk factor for UTI during treatment. Events consistent with genital infections occurred more frequently with empagliflozin 10/25 mg than placebo (3.54 vs. 0.95/100 patient-years, respectively). The frequency of AEs consistent with volume depletion was similar across groups, but higher with empagliflozin 10/25 mg than placebo in patients aged 75 to < 85 years and those on loop diuretics at baseline.ConclusionThis comprehensive analysis confirms that both empagliflozin 10 mg and 25 mg are well tolerated in patients with T2DM, reinforcing the established clinical safety profile of empagliflozin.

Project description:IntroductionCanagliflozin is a sodium glucose co-transporter 2 inhibitor approved worldwide for the treatment of patients with type 2 diabetes mellitus (T2DM). The present study evaluated pharmacokinetics, pharmacodynamics, and safety of canagliflozin in Japanese patients with T2DM.MethodsCanagliflozin, at doses of 25, 100, 200, or 400 mg, was administered as a single dose and, after a washout of 1 day, in repeated doses for 14 consecutive days to 61 subjects in a randomized, double-blind, placebo-controlled study. Plasma concentrations of canagliflozin and urinary glucose excretion (UGE) were measured, and renal threshold for glucose excretion (RTG) was calculated. Safety was evaluated on the basis of adverse event (AE) reports, blood and urine laboratory parameters, and vital signs.ResultsPlasma canagliflozin maximum concentration and area under the concentration-time curve (AUC) values increased in a dose-dependent manner with the time to maximum concentration (t max) of 1.0 h and elimination half-life (t 1/2) of 10.22-13.26 h on Day 1. No significant changes in t max and t 1/2 were observed after multiple-dose administration. The linearity factors, as calculated from the ratios of AUC0-24h on Day 16 to AUC0-∞ on Day 1, were close to 1 in all canagliflozin groups. Canagliflozin increased UGE0-24h (80-110 g/day with canagliflozin ≥100 mg) and decreased RTG from the first day of treatment; these effects were sustained during the entire period of multiple administration. No significant AEs were noted. Urine volume was slightly increased on Day 1, but subsequent changes after repeated doses for 14 days were small. Urinary sodium tended to be higher in the early treatment period, whereas no particular change was observed in serum osmolality and hematocrit.ConclusionCanagliflozin increased UGE, decreased RTG, and was well tolerated throughout the entire period of multiple administrations in Japanese patients with T2DM.FundingMitsubishi Tanabe Pharma Corporation.Trial registrationClinicalTrials.gov#NCT00707954.
