Pharmacokinetics and Pharmacodynamics of Luseogliflozin, a Selective SGLT2 Inhibitor, in Japanese Patients With Type 2 Diabetes With Mild to Severe Renal Impairment.

ABSTRACT: This open-label, parallel-group, multicenter study aimed to assess the effects of renal impairment on the pharmacokinetics, pharmacodynamics, and safety of luseogliflozin. A single 5-mg dose of luseogliflozin was administered to Japanese patients with type 2 diabetes mellitus in the following groups: G1, normal renal function; G2, mild renal impairment; G3a, mild to moderate impairment; G3b, moderate to severe impairment; G4, severe impairment, based on estimated glomerular filtration rate (eGFR; ?90, 60-89, 45-59, 30-44, 15-29 mL/min/1.73 m2 , respectively). While luseogliflozin pharmacokinetics were similar for patients across all renal function groups, the increase in plasma concentration was slightly slower and maximum concentration was slightly reduced in the lower eGFR groups compared with the other groups. However, luseogliflozin pharmacodynamics were affected by the severity of renal impairment. Urinary glucose excretion (UGE) increased in all groups relative to baseline levels, but the degree of UGE increase was smaller in the lower eGFR groups. Moreover, plasma glucose AUC changes from baseline tended to be smaller in the lower eGFR groups. No clear trends were observed between eGFR and incidence, type, or severity of adverse events. Thus, luseogliflozin administration should be carefully considered, as patients with renal impairment may show an insufficient response to treatment.

Project description:IntroductionLuseogliflozin, a potent, selective sodium glucose cotransporter 2 inhibitor, promotes urinary glucose excretion (UGE) and reduces plasma glucose concentrations. Luseogliflozin was approved for use in Japan after favorable pharmacokinetic, pharmacodynamic, and safety profiles were reported in healthy Japanese subjects and patients with type 2 diabetes mellitus (T2DM) in clinical development studies. We aimed to investigate the pharmacokinetics, pharmacodynamics, and safety of multiple doses of luseogliflozin administered once daily for 7 days in Japanese patients with T2DM.MethodsWe conducted a randomized, placebo-controlled, single-blind, parallel-group, clinical pharmacology study at the P-One Clinic, Keikokai Medical Corporation (Tokyo, Japan) between August 2009 and November 2009. Forty Japanese patients with T2DM were randomly assigned to receive once-daily 0.5, 1, 2.5 or 5 mg luseogliflozin or placebo for 7 days. We assessed the pharmacokinetics, pharmacodynamics (including changes in UGE and plasma glucose concentrations), and safety of luseogliflozin.ResultsThe plasma concentrations of luseogliflozin and its active metabolite, M2, were dose proportional, without accumulation. 24-h UGE was greater in all luseogliflozin groups versus placebo. Least-squares mean differences in 24-h UGE on Day 7 increased dose dependently in the luseogliflozin groups, with values of 49.2, 66.5, 89.4, and 101 g/day at 0.5, 1, 2.5, and 5 mg, respectively. On Day 7, the areas under the concentration-time curves for post-meal plasma glucose and the mean plasma glucose for 0-16 h were significantly lower in all luseogliflozin groups versus placebo. Seven patients had mild adverse events (AEs); all were resolved. No AEs led to study discontinuation.ConclusionOnce-daily administration of luseogliflozin for 7 days increased 24-h UGE in a dose-dependent manner, reduced plasma glucose concentrations, and was well tolerated in Japanese patients with T2DM. The pharmacokinetic and pharmacodynamic profile of luseogliflozin observed in this study supports its once-daily dosing regimen.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.
