Project description:This randomized, double-blind, placebo-controlled, crossover study was the first to determine the effects of luseogliflozin in combination with a low-carbohydrate diet (LCD) on 24-h glucose variability, assessed by continuous glucose monitoring (CGM). A total of 18 Japanese patients with type 2 diabetes were randomized into two groups, in which patients first received luseogliflozin 2.5?mg once daily then placebo for 8?days each, or vice versa. Patients took luseogliflozin or placebo with a normal-carbohydrate diet (NCD) on day 7 and with the LCD on day 8. CGM was performed on both days. Luseogliflozin significantly reduced glucose exposure in terms of the area under the curve over the course of 24?h when administered with the NCD (difference vs placebo: -555.6?mg/dl·h [1?mg/dl?=?0.0556?mmol/l]; p?<?0.001) or with the LCD (-660.7?mg/dl·h; p?<?0.001). No hypoglycaemia was observed over 24?h with either diet. Although glucose levels were lower with the LCD than with the NCD in the placebo treatment period, luseogliflozin with the LCD improved glycaemic control throughout the day to nearly the same extent as luseogliflozin with the NCD, without inducing hypoglycaemia.

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.

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:INTRODUCTION:Sodium glucose co-transporter-2 inhibitors (SGLT2i) have been on the market for 5 years in Japan. We explored the real-world effectiveness of SGLT2i in Japan. METHODS:We retrospectively analyzed two large Japanese administrative databases from JMDC Inc.: insurance-dataset (I-dataset) and Medical Data Vision Co. Ltd. [hospital-dataset (H-dataset)]. Patients who newly started SGLT2i or other oral antidiabetic drugs (OADs) between 1 April 2014 and 31 March 2016 were selected for this analysis and followed for 1 year from the index date. Changes in glycated hemoglobin (HbA1c), body mass index (BMI), and estimated glomerular filtration rate (eGFR) were evaluated during the 1-year period. RESULTS:A total of 127,961 patients in the H-dataset and 26,436 in the I-dataset were included in this analysis. Baseline HbA1c, BMI, and eGFR levels tended to be higher in SGLT2i users than in other OAD cohorts. After 1 year, 44.3% (I-dataset) and 53.3% (H-dataset) of SGLT2i users and 33.0-44.2% (I-dataset) and 47.0-58.1% (H-dataset) of other users were still on their medications. The mean HbA1c level decreased by - 0.7 to - 0.9% in SGLT2i users versus - 0.4 to - 1.5% in the other cohorts. The mean BMI decreased by - 0.8 kg/m2 in SGLT2i users whereas the change in other cohorts was - 0.5 to 0.4 kg/m2. No clinically relevant changes in eGFR were observed over the period. CONCLUSION:This study showed that around half of the SGLT2i users were still on medication after 1 year from treatment initiation. Initiation of SGLT2i was associated with improvement in HbA1c and BMI, with no abnormal changes in renal function observed in the first year following treatment. These findings support the results from clinical trials and will expand the existing evidence of SGLT2i use in real-life practice in Japan. FUNDING:Astellas Pharma Inc., Tokyo, Japan.

Project description:Adjunctive therapies to insulin for treatment of type 1 diabetes mellitus (T1D) have gained popularity in efforts to achieve glycemic targets, and sodium-glucose transporter (SGLT) inhibitors are an appealing option due to associated weight loss, low risk of hypoglycemia, and improved cardiorenal outcomes seen in persons with type 2 diabetes mellitus. The increased risk of diabetic ketoacidosis (DKA), including euglycemic DKA, has led many to be wary of their use in T1D, especially given limited pediatric data and data regarding cardiorenal protection in this population. The phase 3 trials of these agents in T1D have yielded lower HbA1c, decreased total daily insulin dose, and small but significant weight loss with no increase in hypoglycemia. These trials also reported increased risks of genital mycotic infection and DKA. SGLT inhibitors have been approved as adjunctive therapy to insulin in adults with T1D in Europe and Japan, but the United States Food and Drug Administration has rejected similar applications. Although approaches to mitigate the risk of DKA have been developed, no randomized trials using such tools have been conducted. More research is needed to minimize the risk of DKA and to better evaluate the cardiorenal impact of these agents in persons with T1D.

Project description:Purpose of reviewSodium-glucose co-transporter-2 (SGLT2) inhibitors are the newest class of oral antihyperglycemic agents that have been approved for the treatment of diabetes mellitus. Over the past year, there have been significant developments in both the safety and efficacy of this class of medications that are presented in this review.Recent findingsApart from data on the glucose-lowering effect of SGLT2 inhibitors, other metabolic benefits have been demonstrated for this class of medications. Moreover, there have been three Food and Drug Administration Drug Safety Communications issued in 2015 that have led to additional drug labeling. The basic mechanism of action, indications, glucose-lowering benefits, other metabolic benefits, and adverse side-effects of SGLT2 inhibitors are presented in this review.SummarySGLT2 inhibitors are medications that have a unique mechanism of action and that lower glucose independent of insulin. Given the recent findings on efficacy and benefits, these agents are rapidly establishing their role in the treatment of diabetes. Especially in patients with type 2 diabetes not willing or not ready to start insulin, SGLT2 inhibitors may be another option in those patients requiring additional glucose lowering and in those with acceptable risk factor profiles. Although there appears to be some positive benefits in cardiovascular endpoints, more research on the long-term outcomes in people taking SGLT2 inhibitors is warranted.

Project description:Although sodium-glucose cotransporter 2 (SGLT2) inhibitors lower serum uric acid, their long-term effect on uric acid metabolism is not well understood. We analyzed pooled data from studies wherein patients with type 2 diabetes mellitus received luseogliflozin, an SGLT2 inhibitor. Upon stratifying patients by baseline glycated hemoglobin (HbA1c ) or serum uric acid, lower HbA1c or higher serum uric acid level was associated with a greater reduction in serum uric acid after treatment. At week 12 of treatment, significant increases in urinary glucose/creatinine (Cr) ratio and urinary uric acid clearance/Cr clearance ratio (CUA /CCr ratio) and a significant reduction in serum uric acid were observed. Comparison of the subgroups of patients with a reduction or an increase in serum uric acid showed that the increase subgroup had a higher estimated glomerular filtration rate (eGFR) at baseline, and the eGFR was significantly reduced, associated with a significant reduction in the CUA /CCr ratio. Multiple regression analysis showed that the reduction in serum uric acid in the luseogliflozin group was strongly associated with baseline high serum uric acid, low HbA1c levels, and an increase in eGFR. Luseogliflozin was shown to reduce serum uric acid by enhancing urinary uric acid excretion in association with increased urinary glucose. Treatment with luseogliflozin resulted in increased serum uric acid in some patients, which may be due to reduced glomerular filtration of uric acid via the tubuloglomerular feedback. SGLT2 inhibitors reduced serum uric acid desirably in patients with type 2 diabetes mellitus with low HbA1c and high serum uric acid.

Project description:AIMS/INTRODUCTION:It is unclear how changes in body composition induced by sodium-glucose cotransporter 2 (SGLT2) inhibitor treatment correlate with metabolic profile changes. We aimed to clarify how metabolic profile changes correlate with body component changes, and if SGLT2 inhibitor treatment causes sarcopenia and bone mineral content (BMC) loss. MATERIALS AND METHODS:Moderately obese Japanese type 2 diabetes patients, treated with luseogliflozin for a year, were observed prospectively and evaluated for body composition changes. We analyzed the changes in the individual body components during treatment, and their correlation with other clinical variables. RESULTS:The efficacy analysis set comprised 37 of 43 enrolled patients. The total fat mass significantly decreased early in the treatment at and after week 4, with a mean decrease of -1.97 kg (95% confidence interval -2.66 to -1.28) at week 24. The visceral fat area at week 24 showed an average downward trend, although this was not significant. The changes in visceral fat area in individual patients showed a significant negative correlation with the extent of the baseline visceral fat area (r = -0.399, P = 0.023). The skeletal muscle mass index showed a significant but small change at and after week 36. The BMC profile showed a transient significant decrease only at week 12. No significant change in BMC was noted at other time-points. CONCLUSIONS:Luseogliflozin treatment brought about favorable changes in body composition and metabolism of moderately obese Japanese type 2 diabetes patients, accompanied by body fat reduction, and minimal muscle and BMC reduction.

Project description:Inhibitors of sodium-glucose co-transporter 2 (SGLT2) have immediate glucose-lowering effects by promoting urinary glucose excretion, without altering insulin level. Only a few studies have evaluated blood glucose dynamics in the early period after administration. The present retrospective study was designed to determine the immediate effects of SGLT2 inhibitors on blood glucose dynamics.The study subjects were 24 patients with type 2 diabetes whose blood glucose dynamics were evaluated with continuous glucose monitoring for 1 week before and after initiation of SGLT2 inhibitor therapy. Blood glucose dynamics were examined on days -1, 0 (treatment commencement day), 3, and 7 by evaluating different continuous glucose monitoring parameters and blood glucose before each meal. Furthermore, blood glucose levels at 1 and 2 h after each meal and daily urinary glucose levels were determined.A significant reduction in blood glucose levels 2 h after breakfast was observed between the day before treatment (249.8 mg/dL) and the day treatment started (218.9 mg/dL). The mean daily blood glucose level improved significantly from 201.4 to 142.3 mg/dL from the day the treatment started. Blood glucose variation also improved significantly by week 1, as demonstrated by changes in standard deviation and mean amplitude of glycemic excursions (from 39.6 to 31.7 and 106.9 to 87.4 mg/dL, respectively). The percent time at blood glucose <70 mg/dL remained unchanged while urinary glucose on day 7 correlated with minimum blood glucose level (r = 0.474, p = 0.022).The results showed that the SGLT2 inhibitors lower blood glucose from 2 h after the first dose and improve blood glucose variation by week 1 after start of the treatment. Furthermore, SGLT2 inhibitors did not alter the incidence of hypoglycemic episodes at week 1, suggesting that SGLT2 protects against severe hypoglycemia by inhibiting urinary glucose excretion.

Project description:BACKGROUND:Metformin is the first-line treatment for type 2 diabetes mellitus (T2DM), but many patients either cannot tolerate it or cannot achieve glycemic control with metformin alone, so treatment with other glucose-lowering agents in combination with metformin is frequently required. Remogliflozin etabonate, a novel agent, is an orally bioavailable prodrug of remogliflozin, which is a potent and selective sodium-glucose co-transporter-2 inhibitor. OBJECTIVE:Our objective was to evaluate the efficacy and safety of remogliflozin etabonate compared with dapagliflozin in subjects with T2DM in whom a stable dose of metformin as monotherapy was providing inadequate glycemic control. METHODS:A 24-week randomized, double-blind, double-dummy, active-controlled, three-arm, parallel-group, multicenter, phase III study was conducted in India. Patients aged???18 and???65 years diagnosed with T2DM, receiving metformin???1500 mg/day, and with glycated hemoglobin (HbA1c) levels???7 to???10% at screening were randomized into three groups. Every patient received metformin???1500 mg and either remogliflozin etabonate 100 mg twice daily (BID) (group 1, n?=?225) or remogliflozin etabonate 250 mg BID (group 2, n?=?241) or dapagliflozin 10 mg once daily (QD) in the morning and placebo QD in the evening (group 3, n?=?146). The patients were followed-up at weeks 1 and 4 and at 4-week intervals thereafter until week 24. The endpoints included mean change in HbA1c (primary endpoint, noninferiority margin?=?0.35), fasting plasma glucose (FPG), postprandial plasma glucose (PPG), bodyweight, blood pressure, and fasting lipids. Treatment-emergent adverse events (TEAEs), safety laboratory values, electrocardiogram, and vital signs were evaluated. RESULTS:Of 612 randomized patients, 167 (group 1), 175 (group 2), and 103 (group 3) patients with comparable baseline characteristics completed the study. Mean change?±?standard error (SE) in HbA1c from baseline to week 24 was -?0.72?±?0.09, -?0.77?±?0.09, and -?0.58?±?0.12% in groups 1, 2, and 3, respectively. The difference in mean HbA1c of group 1 versus group 3 (-?0.14%, 90% confidence interval [CI] -?0.38 to 0.10) and group 2 versus group 3 (-?0.19%; 90% CI -?0.42 to 0.05) was noninferior to that in group 3 (p?<?0.001). No significant difference was found between group 1 or group 2 and group 3 in change in FPG, PPG, and bodyweight. The overall incidence of TEAEs was comparable across study groups (group 1?=?32.6%, group 2?=?34.4%, group 3?=?29.5%), including adverse events (AEs) of special interest (hypoglycemic events, urinary tract infection, genital fungal infection). Most TEAEs were mild to moderate in intensity, and no severe AEs were reported. CONCLUSION:This study demonstrated the noninferiority of remogliflozin etabonate 100 and 250 mg compared with dapagliflozin, from the first analysis of an initial 612 patients. Remogliflozin etabonate therefore may be considered an effective and well-tolerated alternative treatment option for glycemic control in T2DM. TRIAL REGISTRATION:CTRI/2017/07/009121.
