Que L, Huang K, Xiang X, Ding Y, Chu N, He Q. No apparent pharmacokinetic interactions were found between henagliflozin: A novel sodium-glucose co-transporter 2 inhibitor and glimepiride in healthy Chinese male subjects. J Clin Pharm Ther 2022; 47:1225-1231. [PMID: 35362180 DOI: 10.1111/jcpt.13659] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Revised: 03/05/2022] [Accepted: 03/16/2022] [Indexed: 12/20/2022]
Abstract
WHAT IS KNOWN AND OBJECTIVE Henagliflozin is a novel selective sodium-glucose co-transporter 2 (SGLT2) inhibitor with similar inhibitory effect to ertugliflozin. Glimepiride is widely used to treat type 2 diabetes mellitus (T2DM) with few cardiovascular side effects. In the present study, we aimed at evaluating the pharmacokinetic (PK) interactions between henagliflozin and glimepiride. METHODS An open-label, single-centre, single-arm, 3-period, 3-treatment, self-control study was conducted in twelve healthy Chinese male subjects. During each study period, subjects received a single oral dose of glimepiride 2 mg, multiple oral doses of henagliflozin 10 mg or a combination of the two drugs. Serial blood samples were collected 24 h post-dosing for PK analyses. Finger-tip blood glucose was also tested for safety evaluation. RESULTS AND DISCUSSION Co-administration of henagliflozin with glimepiride did not affect their plasma PK profiles. For henagliflozin, the 90% confidence intervals for the geometric mean ratio (GMR) for the maximum plasma concentrations at steady-state (Cmax ss ) and the area under the plasma concentration-time curve during a dosing interval at steady-state (AUCτ, ss ) of combination therapy to henagliflozin alone were 1.00 (0.93-1.08) and 1.00 (0.98-1.02), respectively. For glimepiride, the corresponding values of combination therapy to glimepiride alone were 1.00 (0.88-1.13) for maximum plasma concentrations (Cmax ), 0.91 (0.84-0.99) for the area under the plasma concentration-time curve from 0-24 h (AUC0-24h ) and 0.91 (0.83-1.00) for the plasma concentration-time curve from 0 h to infinite (AUC0-inf ), respectively. All values fell within the equivalence range of 0.8-1.25. All monotherapies and combination therapy led to no serious adverse events and were well tolerated. WHAT IS NEW AND CONCLUSION Multiple doses of henagliflozin did not exert a significant change on glimepiride PK profiles and a single dose of glimepiride had little effect on henagliflozin blood concentration. Thus, henagliflozin can be co-administered with glimepiride without dose adjustment of either drug.

Abstract
Type 2 diabetes mellitus is a multifactorial condition characterized by high level of sugar in the blood. To control hyperglycemia, combination therapy is recommended if monotherapy fails to achieve glycemic control. The combination of a dipeptidyl peptidase-4 (DPP-4) inhibitor and a sodium-glucose cotransporter type 2 (SGLT2) inhibitor is a promising option of the combination therapies in terms of safety as well as efficacy. Despite of the value of combination therapy of these two agents, the pharmacokinetic drug interactions between these two classes of agents have been evaluated in a few drugs. Thus, we reviewed the potential pharmacokinetic drug interaction based on the in vitro metabolism- and transporter-mediated drug interaction information as well as drug interaction studies in human, between a DPP-4 inhibitor and a SGLT2 inhibitor which are marketed in South Korea.

Abstract
Diabetes mellitus currently affects as many as 400 million people worldwide, creating a heavy economic burden and stretching health care resources. A dysfunction of glucose homeostasis underlies the disease. Despite advances in the treatment of diabetes, many patients still suffer from complications and side effects; hence, development of more effective treatments for diabetes is still desirable. SGLT2 is the principle cotransporter involved in glucose reabsorption in the kidney. SGLT2 inhibition reduces glucose reabsorption by the kidney and ameliorates plasma glucose concentration. The interest in natural products that can be used for the inhibition of SGLT2 is growing. The flavonoid phlorizin, which can be isolated from the bark of apple trees, has been used as lead structure due to its inhibitory activity of SGLT1 and SGLT2. Some phlorizin-derived synthetic compounds, including canagliflozin, dapagliflozin, empagliflozin, ipragliflozin, and ertugliflozin, are approved by the food and drug administration to treat type 2 diabetes mellitus (T2DM), whereas others are under clinical trials investigation. In addition, other natural product-derived compounds have been investigated for their ability to improve blood glucose control. The present review summarizes the natural products with SGLT2 inhibitory activity, and the synthetic compounds obtained from them, and discusses their application for the treatment of diabetes.

Abstract
AIM Ipragliflozin is a new antidiabetic agent that works through enhancing renal glucose excretion. We aim to synthesize evidence from published randomized controlled trials (RCTs) on the safety and efficacy of ipragliflozin in the management of type 2 diabetes mellitus (T2DM). METHODS We searched PubMed, Scopus, Web of Science, and Cochrane Central register of clinical trials using relevant keywords. Records were screened for eligible studies and data were extracted and synthesized using Review Manager Version 5.3 for windows. Subgroup and sensitivity analyses were conducted. RESULTS We included 13 RCTs (N=2535 patients) in the final analysis. The overall effect estimates favoured ipragliflozin 50mg monotherapy group over placebo in terms of: HbA1c (Standardized mean difference (SMD)=-1.20%, 95% Confidence interval (95% CI)=[-1.47, -0.93]; p<0.001), fasting plasma glucose (SMD=-1.30 mg/dL, 95% CI [-1.93, -0.67]; p<0.001), fasting serum insulin (SMD=-1.64 μU/mL, 95% CI [-2.70, -0.59]; p=0.002), and body weight (SMD=-0.85 kg, 95% CI [-1.19, -0.51]; p<0.001). Similarly, better glycemic control and significant body weight reduction compared to placebo were attained in ipragliflozin 50 mg combination with metformin, insulin with/without dipeptidyl peptidase-4 inhibitor, sulfonylurea, and pioglitazone. Ipragliflozin, either alone or in combination, exhibits acceptable safety profile. CONCLUSION The presented meta-analysis provides class one evidence that ipragliflozin is safe and effective in the management of T2DM either as monotherapy or an add-on.

Abstract
Type 2 diabetes (T2D) generally requires a combination of several pharmacological approaches to control hyperglycaemia. Combining a sodium-glucose cotransporter type 2 inhibitor (SGLT2I, also known as gliflozin) and a dipeptidyl peptidase-4 inhibitor (DPP-4I, also known as gliptin) appears to be an attractive strategy because of complementary modes of action. This narrative review analyzes the pharmacokinetics and clinical efficacy of different combined therapies with an SGLT2I (canagliflozin, dapagliflozin, empagliflozin, ertugliflozin, ipragliflozin, luseogliflozin, tofogliflozin) and DPP-4I (linagliptin, saxagliptin, sitagliptin, teneligliptin). Drug-drug pharmacokinetic interaction studies do not show any significant changes in peak concentrations (C max) and total exposure (area under the curve of plasma concentrations [AUC]) of either drug when they were administered together orally compared with corresponding values when each of them was absorbed alone. Two fixed-dose combinations (FDCs) are already available (dapagliflozin-saxagliptin, empagliflozin-linagliptin) and others are in development (ertugliflozin-sitagliptin). Preliminary results show bioequivalence of the two medications administered as FDC tablets when compared with coadministration of the individual tablets. Dual therapy is more potent than either monotherapy in patients treated with diet and exercise or already treated with metformin. SGLT2I and DPP-4I could be used as initial combination or in a stepwise approach. The additional glucose-lowering effect appears to be more marked when a gliflozin is added to a gliptin than when a gliptin is added to a gliflozin. Combining the two pharmacological options is safe and does not induce hypoglycaemia.

Abstract
Inter-individual variability in pharmacokinetics can lead to unexpected side effects and treatment failure, and is therefore an important factor in drug development. CYP2C8 is a major drug-metabolizing enzyme known to be involved in the metabolism of over 100 drugs. In this study, we predicted the inter-individual variability in AUC/Dose of CYP2C8 substrates in healthy volunteers using the Monte Carlo simulation. Inter-individual variability in the hepatic intrinsic clearance of CYP2C8 substrates (CLint,h,2C8) was estimated from the inter-individual variability in pharmacokinetics of pioglitazone, which is a major CYP2C8 substrate. The coefficient of variation (CV) of CLint,h,2C8 was estimated to be 40%. Using this value, the CVs of AUC/Dose of other major CYP2C8 substrates, rosiglitazone and amodiaquine, were predicted to validate the estimated CV of CLint,h,2C8. As a result, the reported CVs of both substrates were within the 2.5-97.5 percentile range of the predicted CVs. Furthermore, the CVs of AUC/Dose of the CYP2C8 substrates loperamide and chloroquine, which are affected by renal clearance, were also successfully predicted. Combining this value with previously reported CVs of other CYPs, we were able to successfully predict the inter-individual variability in pharmacokinetics of various drugs in clinical.

Abstract
INTRODUCTION Type 2 diabetes (T2D) is a complex disease with multiple defects, which generally require a combination of several pharmacological approaches to control hyperglycemia. Combining a dipeptidyl peptidase-4 inhibitor (DPP-4i) and a sodium-glucose cotransporter type 2 inhibitor (SGT2i) appears to be an attractive approach. Area covered: An extensive literature search was performed to analyze the pharmacokinetics, pharmacodynamics and clinical experience of different gliptin-gliflozin combinations. Expert opinion: There is a strong rationale for combining a DPP-4i and a SGLT2i in patients with T2D because the two drugs exert different and complementary glucose-lowering effects. Dual therapy (initial combination or stepwise approach) is more potent than either monotherapy in patients treated with diet and exercise or already treated with metformin. Combining the two pharmacological options is safe and does not induce hypoglycemia. The additional glucose-lowering effect is more marked when a gliflozin is added to a gliptin than when a gliptin is added to a gliflozin. Two fixed-dose combinations (FDCs) are already available (saxagliptin-dapagliflozin and linagliptin-empagliflozin) and others are in current development. Bioequivalence of the two compounds given as FDC tablets was demonstrated when compared with coadministration of the individual tablets. FDCs could simplify the anti-hyperglycaemic therapy and improve drug compliance.

Abstract
Inhibitors of sodium-glucose co-transporter type 2 (SGLT2) are proposed as a novel approach for the management of type 2 diabetes mellitus (T2DM). Several compounds are already available in many countries (dapagliflozin, canagliflozin, empagliflozin and ipragliflozin) and some others are in a late phase of development. The available SGLT2 inhibitors share similar pharmacokinetic characteristics, with a rapid oral absorption, a long elimination half-life allowing once-daily administration, an extensive hepatic metabolism mainly via glucuronidation to inactive metabolites, the absence of clinically relevant drug-drug interactions and a low renal elimination as parent drug. SGLT2 co-transporters are responsible for reabsorption of most (90 %) of the glucose filtered by the kidneys. The pharmacological inhibition of SGLT2 co-transporters reduces hyperglycaemia by decreasing renal glucose threshold and thereby increasing urinary glucose excretion. The amount of glucose excreted in the urine depends on both the level of hyperglycaemia and the glomerular filtration rate. Results of numerous placebo-controlled randomised clinical trials of 12-104 weeks duration have shown significant reductions in glycated haemoglobin (HbA1c), resulting in a significant increase in the proportion of patients reaching HbA1c targets, and a significant lowering of fasting plasma glucose when SGLT2 inhibitors were administered as monotherapy or in addition to other glucose-lowering therapies including insulin in patients with T2DM. In head-to-head trials of up to 2 years, SGLT2 inhibitors exerted similar glucose-lowering activity to metformin, sulphonylureas or sitagliptin. The durability of the glucose-lowering effect of SGLT2 inhibitors appears to be better; however, this remains to be more extensively investigated. The risk of hypoglycaemia was much lower with SGLT2 inhibitors than with sulphonylureas and was similarly low as that reported with metformin, pioglitazone or sitagliptin. Increased renal glucose elimination also assists weight loss and could help to reduce blood pressure. Both effects were very consistent across the trials and they represent some advantages for SGLT2 inhibitors when compared with other oral glucose-lowering agents. The pharmacodynamic response to SGLT2 inhibitors declines with increasing severity of renal impairment, and prescribing information for each SGLT2 inhibitor should be consulted regarding dosage adjustments or restrictions in moderate to severe renal dysfunction. Caution is also recommended in the elderly population because of a higher risk of renal impairment, orthostatic hypotension and dehydration, even if the absence of hypoglycaemia represents an obvious advantage in this population. The overall effect of SGLT2 inhibitors on the risk of cardiovascular disease is unknown and will be evaluated in several ongoing prospective placebo-controlled trials with cardiovascular outcomes. The impact of SGLT2 inhibitors on renal function and their potential to influence the course of diabetic nephropathy also deserve more attention. SGLT2 inhibitors are generally well-tolerated. The most frequently reported adverse events are female genital mycotic infections, while urinary tract infections are less commonly observed and generally benign. In conclusion, with their unique mechanism of action that is independent of insulin secretion and action, SGLT2 inhibitors are a useful addition to the therapeutic options available for the management of T2DM at any stage in the natural history of the disease. Although SGLT2 inhibitors have already been extensively investigated, further studies should even better delineate the best place of these new glucose-lowering agents in the already rich armamentarium for the management of T2DM.

Abstract
Ipragliflozin (Suglat(®)) is a potent and selective inhibitor of sodium-glucose cotransporter-2 that was recently launched in Japan. Its mechanism of action involves the suppression of glucose re-absorption in the kidney proximal tubules, causing excretion of glucose in the urine. The aim of this review is to provide a comprehensive overview of currently available pharmacokinetic and pharmacodynamic data on ipragliflozin, including studies in healthy subjects, patients with type 2 diabetes mellitus and special populations. In single- and multiple-dose studies, the maximum plasma concentration and area under the plasma concentration-time curve (AUC) for ipragliflozin increased in a dose-dependent manner. Although urinary excretion of ipragliflozin is low (approximately 1 %), tubular concentration of free ipragliflozin is adequate to provide pharmacological activities. No clinically relevant effects of age, gender or food on the exposure of ipragliflozin were observed. The AUC for ipragliflozin was 20-30 % greater in patients with moderate renal or hepatic impairment than in patients with normal renal or hepatic function. In drug-drug interaction studies, the pharmacokinetics of ipragliflozin and other oral antidiabetic drugs (metformin, sitagliptin, pioglitazone, glimepiride, miglitol and mitiglinide) were not significantly affected by their co-administration. Urinary glucose excretion (UGE) also increased in a dose-dependent manner, approaching a maximum effect at 50-100 mg dosages in Japanese healthy volunteers and patients with type 2 diabetes. The change in UGE from baseline (ΔUGE) tended to be lower in older subjects and female subjects, compared with younger subjects and male subjects, respectively. ΔUGE tended to decrease with decreasing renal function, especially in patients with type 2 diabetes with moderate or severe renal impairment.

Abstract
Ipragliflozin (Suglat® [Japan]), an orally active, next-generation sodium-glucose transporter 2 (SGLT2) inhibitor, has been developed by Astellas Pharma and Kotobuki Pharmaceutical for the treatment of type 2 diabetes mellitus. Ipragliflozin has received its first global approval in this indication in Japan, for use as monotherapy or in combination with another antihyperglycaemic agent (metformin, pioglitazone, a sulfonylurea, an α-glucosidase inhibitor, a dipeptidylpeptidase-4 inhibitor or nateglinide). Ipragliflozin is the first SGLT2 inhibitor to be approved in Japan. This article summarizes the milestones in the development of ipragliflozin leading to this first approval for the treatment of type 2 diabetes mellitus.

Abstract
Type 2 diabetes is characterized by decreased insulin secretion and sensitivity. The available oral anti-diabetic drugs act on many different molecular sites. The most used of oral anti-diabetic agents is metformin that activates glucose transport vesicles to the cell surface. Others are: the sulphonylureas; agents acting on the incretin system; GLP-1 agonists; dipetidylpeptidase-4 inhibitors; meglinitide analogues; and the thiazolidinediones. Despite these many drugs acting by different mechanisms, glycaemic control often remains elusive. None of these drugs have a primary renal mechanism of action on the kidneys, where almost all glucose excreted is normally reabsorbed. That is where the inhibitors of glucose reuptake (sodium-glucose cotransporter 2, SGLT2) have a unique site of action. Promotion of urinary loss of glucose by SGLT2 inhibitors embodies a new principle of control in type 2 diabetes that has several advantages with some urogenital side-effects, both of which are evaluated in this review. Specific approvals include use as monotherapy, when diet and exercise alone do not provide adequate glycaemic control in patients for whom the use of metformin is considered inappropriate due to intolerance or contraindications, or as add-on therapy with other anti-hyperglycaemic medicinal products including insulin, when these together with diet and exercise, do not provide adequate glycemic control. The basic mechanisms are improved β-cell function and insulin sensitivity. When compared with sulphonylureas or other oral antidiabetic agents, SGLT2 inhibitors provide greater HbA1c reduction. Urogenital side-effects related to the enhanced glycosuria can be troublesome, yet seldom lead to discontinuation. On this background, studies are analysed that compare SGLT2 inhibitors with other oral antidiabetic agents. Their unique mode of action, unloading the excess glycaemic load, contrasts with other oral agents that all act to counter the effects of diabetic hyperglycaemia.

Abstract
This multicenter, double-blind, placebo-controlled study examined the efficacy and safety of ipragliflozin, a sodium-glucose co-transporter 2 inhibitor, in combination with metformin in Japanese patients with type 2 diabetes mellitus (T2DM). Patients were randomized in a 2 : 1 ratio to 50 mg ipragliflozin (n = 112) or placebo (n = 56) once daily for 24 weeks, followed by a 28-week open-label extension in which all patients received 50 or 100 mg ipragliflozin, while continuing metformin. The primary outcome was the change in glycated haemoglobin (HbA1c) from baseline to week 24. HbA1c decreased significantly in the ipragliflozin group (-0.87%; adjusted mean difference from placebo: -1.30%; p < 0.001). The overall incidence of treatment-emergent adverse events was similar in both groups, although pollakiuria and constipation were more common in the ipragliflozin group; thus, ipragliflozin significantly improved glycaemic control and reduced body weight without major safety issues in Japanese patients with T2DM.

Ohkura T. Ipragliflozin: A novel sodium-glucose cotransporter 2 inhibitor developed in Japan. World J Diabetes 2015; 6:136-144. [PMID: 25685284 PMCID: PMC4317305 DOI: 10.4239/wjd.v6.i1.136] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/24/2014] [Revised: 05/30/2014] [Accepted: 12/01/2014] [Indexed: 02/05/2023] Open
Abstract
Sodium-glucose cotransporter 2 (SGLT2) inhibition induces glucosuria and decreases blood glucose levels in diabetic patients and lowers hypoglycemic risk. SGLT1 is expressed in the kidney and intestine; SGLT1 inhibition causes abdominal symptoms such as diarrhea and reduces incretin secretion. Therefore, SGLT2 selectivity is important. Ipragliflozin is highly selective for SGLT2. In type 2 diabetes mellitus (T2DM), urinary glucose excretion increased to 90 g/24 h after 28 d of treatment with ipragliflozin 300 mg/d. Twelve weeks of ipragliflozin 50 mg/d vs placebo reduced glycated hemoglobin and body weight by 0.65% and 0.66 kg, respectively, in Western T2DM patients, and by 1.3% and 1.89 kg, respectively, in Japanese patients. Ipragliflozin (highly selective SGLT2 inhibitor) improves glycemic control and reduces body weight and lowers hypoglycemic risk and abdominal symptoms. Ipragliflozin can be a novel anti-diabetic and anti-obesity agent.

Abstract
The kidney plays an important role in glucose homeostasis via its production, utilization, and, most importantly, reabsorption of glucose from glomerular filtrate which is largely mediated via the sodium glucose co-transporter 2 (SGLT2). Pharmacological inhibition of SGLT2 increases urinary glucose excretion and decreases plasma glucose levels in an insulin-independent manner. Agents that inhibit SGLT2 represent a novel class of drugs, which has recently become available for treatment of type 2 diabetes. This article summarizes the rationale for use of these agents and reviews available clinical data on their efficacy, safety, and risks/benefits.

Abstract
INTRODUCTION Dipeptidyl-peptidase-4 (DPP-4) inhibitors are a class of anti-hyperglycemic agents with proven efficacy in patients with type 2 diabetes mellitus (T2DM). AREAS COVERED This review considers the pharmacokinetic profile, adverse effects and drug interactions of DPP-4 inhibitors. DPP-4 inhibitors have certain differences in their structure, metabolism, route of elimination and selectivity for DPP-4 over structurally related enzymes, such as DPP-8/DPP-9. They have a low potential for drug interactions, with the exception of saxagliptin that is largely metabolized by cytochrome CYP3A4/A5. Reports of pancreatitis and pancreatic cancer have raised concerns regarding the safety of DPP-4 inhibitors and are under investigation. Post-marketing surveillance has revealed less common adverse effects, especially a number of skin- and immune-related adverse effects. These issues are covered in the present review. EXPERT OPINION DPP-4 inhibitors are useful and efficient drugs. DPP-4 inhibitors have similar mechanism of action and similar efficacy. However, DPP-4 inhibitors have certain differences in their pharmacokinetic properties that may be associated with different clinical effects and adverse event profiles. Although clinical trials indicated a favorable safety profile, post-marketing reports revealed certain safety aspects that need further investigation. Certainly, more research is needed to clarify if the differences among DPP-4 inhibitors could lead to a different clinical and safety profile.

Abstract
The two main sodium-glucose cotransporters (SGLTs), SGLT1 and SGLT2, provide new therapeutic targets to reduce hyperglycaemia in patients with diabetes. SGLT1 enables the small intestine to absorb glucose and contributes to the reabsorption of glucose filtered by the kidney. SGLT2 is responsible for reabsorption of most of the glucose filtered by the kidney. Inhibitors with varying specificities for these transporters (eg, dapagliflozin, canagliflozin, and empagliflozin) can slow the rate of intestinal glucose absorption and increase the renal elimination of glucose into the urine. Results of randomised clinical trials have shown the blood glucose-lowering efficacy of SGLT inhibitors in type 2 diabetes when administered as monotherapy or in addition to other glucose-lowering therapies including insulin. Increased renal glucose elimination also assists weight loss and could help to reduce blood pressure. Effective SGLT2 inhibition needs adequate glomerular filtration and might increase risk of urinary tract and genital infection, and excessive inhibition of SGLT1 can cause gastro-intestinal symptoms. However, the insulin-independent mechanism of action of SGLT inhibitors seems to offer durable glucose-lowering efficacy with low risk of clinically significant hypoglycaemia at any stage in the natural history of type 2 diabetes. SGLT inhibition might also be considered in conjunction with insulin therapy in type 1 diabetes.

Abstract
BACKGROUND Ipragliflozin (ASP1941) is a selective sodium glucose cotransporter 2 inhibitor in clinical development for the treatment of patients with type 2 diabetes mellitus (T2DM). OBJECTIVES The primary objective was to evaluate the safety profile and tolerability of ipragliflozin as a glucose-lowering agent in combination with stable metformin therapy in patients with T2DM. A secondary objective was to evaluate the effect of ipragliflozin on the pharmacokinetic (PK) properties of metformin. METHODS Thirty-six patients with T2DM stable on metformin therapy (850, 1000, or 1500 mg bid) were randomized in a double-blind manner to receive ipragliflozin (300 mg qd; n = 18) or matching placebo (n = 18) for 14 days. Safety profiles, including monitoring of hypoglycemic events, treatment-emergent adverse events (TEAEs), laboratory measurements, and vital signs were assessed throughout the study. The PK properties of metformin and ipragliflozin were determined in plasma. The geometric mean ratio and its 90% CI for the maximum plasma concentration and AUC(0-10) were calculated for metformin + ipragliflozin (day 14) versus metformin alone (day -1). Pharmacodynamic properties were assessed by measurement of urinary glucose excretion over 24 hours (UGE(0-24)). RESULTS All the TEAEs, except 1, were mild. Fifteen TEAEs were observed in the ipragliflozin group (7 of 18 patients [38.9%]), and 19 TEAEs were observed in the placebo group in (8 of 18 patients [44.4%]). Treatment-related TEAEs were reported by 3 of 18 patients (16.7%) receiving metformin + ipragliflozin and by 5 of 18 patients (27.8%) receiving metformin + placebo. No hypoglycemic events (blood glucose level <54 mg/L [to convert to millimoles per liter, multiply by 0.0555]) were observed. The geometric mean ratios for C(max) and AUC(0-10) of metformin + ipragliflozin versus metformin alone were 1.11 (90% CI, 1.03-1.19) and 1.18 (90% CI, 1.08-1.28), respectively. After ipragliflozin treatment, UGE(0-24) on day 14 (74.9 g) was significantly higher than that in the placebo group (3.6 g) and at baseline (3.3 g). CONCLUSIONS Combination treatment for 14 days with ipragliflozin and metformin was well tolerated in patients withT2DM without hypoglycemia. The addition of ipragliflozin (300 mg qd) to metformin therapy did not result in a clinically relevant change in the PK properties of metformin. ClinicalTrials.gov identifier: NCT01302145.
