Effects of luseogliflozin, a sodium-glucose co-transporter 2 inhibitor, on 24-h glucose variability assessed by continuous glucose monitoring in Japanese patients with type 2 diabetes mellitus: a randomized, double-blind, placebo-controlled, crossover study.

ABSTRACT: The aim of the present study was to determine the effects of luseogliflozin on 24-h glucose levels, assessed by continuous glucose monitoring, and on pharmacodynamic variables measured throughout the day. In this double-blind, placebo-controlled, crossover study, 37 patients with type 2 diabetes mellitus inadequately controlled with diet and exercise were randomized into two groups. Patients in each group first received luseogliflozin then placebo for 7 days each, or vice versa. After 7 days of treatment, the mean 24-h glucose level was significantly lower with luseogliflozin than with placebo [mean (95% confidence interval) 145.9 (134.4-157.5) mg/dl vs 168.5 (156.9-180.0) mg/dl; p < 0.001]. The proportion of time spent with glucose levels ≥70 to ≤180 mg/dl was significantly greater with luseogliflozin than with placebo [median (interquartile range) 83.2 (67.7-96.5)% vs 71.9 (46.9-83.3)%; p < 0.001] without inducing hypoglycaemia. The decrease in glucose levels was accompanied by reductions in serum insulin levels throughout the day.

Project description:IntroductionWe investigated the possibilities of drug-drug interactions between luseogliflozin, a sodium-glucose co-transporter-2 inhibitor, and oral antidiabetic drugs (OADs) in healthy Japanese males.MethodsWe conducted six independent studies to investigate potential drug-drug interactions between 5 mg luseogliflozin and the following OADs usually used in Japan: 1 mg glimepiride, 250 mg metformin, 30 mg pioglitazone, 50 mg sitagliptin, 50 mg miglitol, or 0.6 mg voglibose (0.2 mg before each meal). Twelve subjects were enrolled in each study. The glimepiride, metformin, sitagliptin, and miglitol studies were randomized, open-label, single-dose, three-way crossover studies. The pioglitazone and voglibose studies were open-label studies, where a single dose of luseogliflozin was added to multiple doses of pioglitazone or voglibose. The endpoints were the area under the curve from 0 to 24 h (AUC0-24 h) or to infinity (AUCinf) and the maximum concentration (Cmax) of each drug administered alone or in combination.ResultsThe 90% confidence intervals (CIs) of the geometric mean ratio (GMR) for Cmax of luseogliflozin in the pioglitazone and miglitol studies were beyond the reference range for bioequivalence (0.80-1.25) (miglitol: 0.851 [0.761, 0.952]; pioglitazone: 1.16 [1.04, 1.30]). However, the 90% CIs for AUC0-24 h were within the reference range. The 90% CIs of the GMRs for Cmax and AUC0-24 h of pioglitazone were beyond the reference range (Cmax 0.884 [0.746, 1.05]; AUC0-24 h 0.896 [0.774, 1.04]), but the 90% CIs for the active metabolites of pioglitazone were within the reference range. For the other combinations tested, the 90% CIs and GMRs for luseogliflozin and the individual OADs were within the reference range.ConclusionNo clinically meaningful interactions were observed between luseogliflozin and six commonly used OADs in Japan, although there were some changes in the pharmacokinetics of pioglitazone co-administered with luseogliflozin and for luseogliflozin co-administered with miglitol or pioglitazone.FundingTaisho Pharmaceutical Co., Ltd.

Project description:IntroductionWe investigated the impact of reduced renal function on 24-h glucose variability in Japanese patients with type 2 diabetes mellitus (T2DM) treated with luseogliflozin.MethodsIn this double-blind, placebo-controlled, crossover study, 37 Japanese patients with T2DM [glycated hemoglobin (HbA1c) 7.0-10.0%] and estimated glomerular filtration rate (eGFR) ≥45 mL/min/1.73 m(2) were randomized into two groups in which patients first received luseogliflozin then placebo, or vice versa, for 7 days each. Twenty-four-hour glucose variability was measured on day 7 in each period and was compared among patients divided into three groups according to their baseline eGFR (mL/min/1.73 m(2)): normal (≥90; n = 13; normal group), normal-to-mildly reduced renal function (≥75 to <90; n = 12; normal-mild group), and mild-to-moderately reduced renal function (<75; n = 9; mild-moderate group).ResultsThe mean [95% confidence interval (CI)] placebo-subtracted 24-h cumulative urinary glucose excretion (g) was 82.1 (72.7, 91.5), 82.5 (73.4, 91.5), and 62.2 (51.2, 73.3); the placebo-subtracted 24-h mean glucose concentration (mg/dL) was -24.39 (-32.53, -16.26), -28.28 (-39.35, -17.22), and -11.53 (-23.93, 0.86); and the placebo-subtracted peak postprandial glucose (mg/dL) was -26.9 (-46.9, -6.9), -38.1 (-59.6, -16.6), and 1.5 (-25.5, 28.4) in the normal, normal-mild, and mild-moderate groups, respectively. The mean lowest glucose concentrations (placebo vs. luseogliflozin, mg/dL) decreased to similar levels in the normal (115.4 vs. 93.4), normal-mild (121.0 vs. 97.9), and mild-moderate (104.0 vs. 91.1) groups.ConclusionThis post hoc subanalysis revealed that although mild-to-moderately reduced renal function attenuated the glucose-lowering effects of luseogliflozin on peak postprandial glucose, it did not attenuate the effects of luseogliflozin on fasting glucose. These findings may explain the smaller increase in urinary glucose excretion in these patients relative to patients with normal renal function or normal-to-moderately reduced renal function. Further studies may be needed to examine these findings in large populations of patients with T2DM and reduced renal function.Trial registrationJapicCTI-142548.FundingTaisho Pharmaceutical Co., Ltd.
