Evaluation of Age-Related Changes in Teneligliptin Pharmacokinetics in Japanese and European Descent Subjects Using a Physiologically Based Pharmacokinetic Model. Diabetes Ther 2024; 15:763-777. [PMID: 38117459 PMCID: PMC10951162 DOI: 10.1007/s13300-023-01514-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Accepted: 11/17/2023] [Indexed: 12/21/2023] Open
Abstract
INTRODUCTION Drugs often show differing pharmacokinetic (PK) profiles, such as higher plasma concentrations, in older people than in younger people owing to age-related decreases in physiological functions. However, it is difficult to evaluate the PK in older populations. Therefore, we simulated the plasma age-related changes in the PK of teneligliptin, a dipeptidyl peptidase-4 inhibitor, using physiologically based PK (PBPK) models. METHODS The previously developed PBPK model was revalidated by comparison between simulated data and clinical study data that included older subjects (up to 75 years old). We then simulated the plasma concentration-time profiles for teneligliptin at a dose of 20 mg (single and multiple doses) in virtual Japanese (20-70 years old) and European descent (20-98 years old) subjects. PK parameters were calculated by race and age group. RESULTS We confirmed the validity of the previous PBPK model by comparison between simulated data and clinical study data. In the evaluation of age-related changes in PK after single and multiple doses using the PBPK model, the area under the plasma concentration-time curve (AUC) of teneligliptin tended to increase slightly with age in both populations up to 70 years old. However, no clear age-related change in the maximum plasma concentration (Cmax) of teneligliptin was observed. In the European descent subjects aged ≥ 70 years, the AUC tended to increase but the ratio of the change in Cmax was smaller than that in AUC. In both populations, there were positive correlations between AUC and age, but not between Cmax and age. CONCLUSION The simulation using a PBPK model showed a tendency for the AUC of teneligliptin to increase with age, whereas Cmax was less affected by age than AUC.

Abstract
AIM To employ a model-informed drug development approach in facilitating decision making and expediting the clinical progress of cofrogliptin (HSK7653), a novel ultralong-acting dipeptidyl peptidase-4 (DPP-4) inhibitor, for the treatment of type 2 diabetes (T2D) via a biweekly dosing regimen. METHODS Firstly, a population pharmacokinetics and pharmacodynamics (PopPKPD) model was developed using PK and PD data from a single ascending dose study to simulate the PK and PD time profiles of HSK7653 after multiple doses. Secondly, model-based meta-analysis (MBMA) was performed on published clinical studies of Eastern Asian subjects for all DPP-4 inhibitors. We hypothesized a consistent relationship between PK and DPP-4 inhibition in both healthy individuals and in those with T2D, establishing a quantitative correlation between DPP-4 inhibition and HbA1c. Finally, the predicted PK/DPP-4 inhibition/HbA1c profiles were validated by T2D patients in late clinical trials. RESULTS The PK/DPP-4 inhibition/HbA1c profiles of T2D patients treated with HSK7653 matched the modelled data. Our PopPKPD and MBMA models predict multiple ascending dosing PK and PD characteristics from single ascending dosing data, as well as the long-term efficacy in T2D patients, based on healthy subjects. CONCLUSIONS Successful waiver approval for the phase 2b dose-finding study was achieved through model-informed recommendations, facilitating the clinical development of HSK7653 and other DPP-4 inhibitors.

A Critical View over the Newest Antidiabetic Molecules in Light of Efficacy-A Systematic Review and Meta-Analysis. Int J Mol Sci 2023; 24:ijms24119760. [PMID: 37298707 DOI: 10.3390/ijms24119760] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 06/03/2023] [Accepted: 06/03/2023] [Indexed: 06/12/2023] Open
Abstract
The increase in life expectancy without a decrease in the years lived without disability leads to the rise of the population aged over 65 years prone to polypharmacy. The novel antidiabetic drugs can improve this global therapeutic and health problem in patients with diabetes mellitus (DM). We aimed to establish the efficacy (A1c hemoglobin reduction) and safety of the newest antidiabetic drugs (considered so due to their novelty in medical practice use), specifically DPP-4i, SGLT-2i, GLP-1 Ra, and tirzepatide. The present meta-analysis followed the protocol registered at Prospero with the CRD42022330442 registration number. The reduction in HbA1c in the DPP4-i class for tenegliptin was 95% CI -0.54 [-1.1, 0.01], p = 0.06; in the SGLT2-iclass for ipragliflozin 95% CI -0.2 [-0.87, 0.47], p = 0.55; and for tofogliflozin 95% CI 3.13 [-12.02, 18.28], p = 0.69, while for tirzepatide it was 0.15, 95% CI [-0.50, 0.80] (p = 0.65). The guidelines for treatment in type 2 DM are provided from cardiovascular outcome trials that report mainly major adverse cardiovascular events and data about efficacy. The newest antidiabetic non-insulinic drugs are reported to be efficient in lowering HbA1c, but this effect depends between classes, molecules, or patients' age. The newest antidiabetic drugs are proven to be efficient molecules in terms of HbA1c decrease, weight reduction, and safety, but more studies are needed in order to characterize exactly their efficacy and safety profiles.

Abstract
INTRODUCTION Based on pharmacological properties and results from clinical studies, teneligliptin has a great potential to be used as an alternate-day therapy and also the daily dose can be reduced to 10 mg. Clinical data also suggest its excellent efficacy and safety among older subjects. AREAS COVERED We have reviewed and discussed potential approaches using teneligliptin for the treatment of type 2 diabetes mellitus (T2DM) including alternate-day therapy and reduction of dose from 20 mg to 10 mg per day. We have also discussed the potential of teneligliptin to address the needs of older patients with T2DM. EXPERT OPINION It is an excellent option for use in older patients as studies in the geriatric population have shown encouraging results. Teneligliptin has a desirable pharmacokinetic profile that makes it a potential drug for use on an alternate-day basis. Teneligliptin has shown anti-diabetic efficacy even at a dose of 10 mg. These approaches may improve treatment satisfaction and patient compliance and can lower the cost; however, it is crucial to identify the subset of T2DM patients who can obtain maximum benefits. To verify these effects, large clinical investigations need to be planned and robust clinical evidence should be generated.

Abstract
AIMS Hyperglucagonemia occurs in the pathogenesis of type 2 diabetes mellitus (T2DM). In this meta-analysis, we summarized the effects of DPP4 inhibitors on glucagon levels in patients with T2DM. MATERIALS AND METHODS Randomized controlled trials (RCTs) comparing the influence of DPP4 inhibitors on circulating glucagon levels with placebo or other oral antidiabetic drugs (OADs) in patients with T2DM were identified by searches of Medline (PubMed), Embase (Ovid), and CENTER (Cochrane Library). Only studies reporting changes in glucagon level presented as total area under the curve (AUCglucagon) using a meal or oral glucose tolerance test were included. Results were combined using a random-effects model that incorporated potential heterogeneity among the included studies. RESULTS A total of 36 RCTs with moderate to high quality were included. Overall, the numbers of T2DM patients included for the meta-analyses comparing DPP4 inhibitors with placebo and other OADs were 4266 and 1652, respectively. Compared to placebo, DPP4 inhibitors significantly reduced circulating glucagon levels (standard mean difference [SMD]: -0.32, 95% CI: -0.40 to -0.24, P<0.001; I2 = 28%). Analysis of subgroups revealed that study characteristics had no significant effect on results, such as study design (parallel group or crossover), number of patients, mean patient age, proportion of men, baseline HbA1c, duration of diabetes, background therapy, treatment duration, or methods for glucagon measurement (all P for subgroup differences >0.05). Moreover, DPP4 inhibitors significantly reduced glucagon levels compared to other OADs (SMD: -0.35, 95% CI: -0.53 to -0.16, P<0.001; I2 = 66%), and the reduction in glucagon was greater in comparison with insulin secretagogues than in comparison with non-insulin secretagogues (P for subgroup difference =0.03). SYSTEMATIC REVIEW REGISTRATION https://inplasy.com/, identifier INPLASY202280104. CONCLUSIONS DPP4 inhibitors are effective at reducing the circulating postprandial glucagon level in T2DM patients.

Abstract
Recently, it has been suggested that glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide 1 (GLP-1), which play important roles in the homeostasis of glucose metabolism, could be involved in the regulation of bone metabolism. Inhibitors of dipeptidyl peptidase 4 (DPP-4), an enzyme that degrades GIP and GLP-1, are widely used clinically as a therapeutic agent for diabetes. However, the effects of DPP-4 inhibitors on bone metabolism remain unclear. In this study, we investigated the effects of linagliptin, a DPP-4 inhibitor, on bone fragility induced by type 2 diabetes mellitus (T2DM). Non-diabetic mice were used as controls, and T2DM mice were administered linagliptin orally on a daily basis for 12 weeks. In T2DM mice, decreased bone mineral density was observed in the lower limb bones along with low serum osteocalcin levels and high serum tartrate-resistant acid phosphatase-5b (TRAP) levels. In contrast, the decreased serum osteocalcin levels and increased serum TRAP levels observed in T2DM mice were significantly suppressed after the administration of linagliptin 30 mg/kg. Bone histomorphometric analysis revealed a reduced osteoid volume and osteoblast surface with an increase in the eroded surface and number of osteoclasts in T2DM mice. This decreased bone formation and increased bone resorption observed in the T2DM mice were suppressed and trabecular bone volume increased following the administration of 30 mg/kg linagliptin. Collectively, these findings suggest that linagliptin may improve the microstructure of trabecular bone by inhibiting both a decrease in bone formation and an increase in bone resorption induced by T2DM.

Abstract
Sodium-dependent glucose transporter (SGLT) 2 is specifically expressed in the kidney, while SGLT1 is present in the kidneys and small intestine. SGLT2 inhibitors are a class of oral antidiabetic drugs that lower elevated plasma glucose levels by promoting the urinary excretion of excess glucose through the inhibition of renal glucose reuptake. The inhibition selectivity for SGLT2 over SGLT1 (SGLT2/1 selectivity) of marketed SGLT2 inhibitors is diverse, while SGLT2/1 selectivity of canagliflozin is relatively low. Although canagliflozin suppresses postprandial glucose levels, the degree of contribution for SGLT1 inhibition to this effect remains unproven. To analyze the effect of SGLT2 inhibitors on postprandial glucose level, we constructed a novel quantitative systems pharmacology (QSP) model, called human systemic glucose dynamics (HSGD) model, integrating intestinal absorption, metabolism, and renal reabsorption of glucose. This HSGD model reproduced the postprandial plasma glucose concentration-time profiles during a meal tolerance test under different clinical trial conditions. Simulations after canagliflozin administration showed a dose-dependent delay of time (Tmax,glc ) to reach maximum concentration of glucose (Cmax,glc ), and the delay of Tmax,glc disappeared when inhibition of SGLT1 was negated. In addition, contribution ratio of intestinal SGLT1 inhibition to the decrease in Cmax,glc was estimated to be 23%-28%, when 100 and 300 mg of canagliflozin are administered. This HSGD model enabled us to provide the partial contribution of intestinal SGLT1 inhibition to the improvement of postprandial hyperglycemia as well as to quantitatively describe the plasma glucose dynamics following SGLT2 inhibitors.

Abstract
INTRODUCTION Teneligliptin, a dipeptidyl peptidase 4 inhibitor, was approved for the treatment of type 2 diabetes mellitus (T2DM) in Japan in 2012. However, clinical trials of teneligliptin involved limited numbers of elderly patients. Therefore, we investigated the safety and efficacy of teneligliptin in elderly patients with T2DM. METHODS This 3-year follow-up RUBY surveillance registered patients with T2DM who started treatment with teneligliptin between May 2013 and February 2015 in Japan. Collected data included demographics, treatments, adverse drug reactions (ADRs), and laboratory variables. Data were analysed for patients in three age subgroups (< 65, ≥ 65 to < 75, or ≥ 75 years old). Safety was assessed as the incidence of ADRs and efficacy was assessed in terms of glycaemic control, for up to 3 years. RESULTS The ADRs and serious ADRs occurred in 3.35% and 0.65% of 4596 patients aged < 65 years, in 4.42% and 1.22% of 3371 patients aged ≥ 65 to < 75 years, and in 3.99% and 1.69% of 2729 patients aged ≥ 75 years. The most common ADRs in patients aged ≥ 65 to < 75 years and ≥ 75 years were gastrointestinal disorders, but the incidence of these ADRs did not show an age-dependent increase. Hypoglycaemia occurred in 0.24%, 0.56%, and 0.29% of patients in each age subgroup, respectively. The least-squares mean changes in glycosylated haemoglobin (HbA1c) adjusted for baseline were - 0.66 ± 0.02% (n = 2177), - 0.72 ± 0.02% (n = 1689), and - 0.77 ± 0.03% (n = 1161) at 3 years. CONCLUSION There was no clear difference in the number of ADRs among the three age subgroups, although the incidence of serious ADRs was higher in elderly patients than in patients aged < 65 years. We found no additional safety or efficacy concerns among elderly patients beyond those already described in the package insert. The present results support the use of teneligliptin in elderly patients with T2DM in real-world clinical practice. TRIAL REGISTRATION Japic Clinical Trials Information identifier, Japic CTI-153047.

Combined Treatment with Sodium-Glucose Cotransporter-2 Inhibitor (Canagliflozin) and Dipeptidyl Peptidase-4 Inhibitor (Teneligliptin) Alleviates NASH Progression in A Non-Diabetic Rat Model of Steatohepatitis. Int J Mol Sci 2020; 21:ijms21062164.

Abstract
Hepatocellular carcinoma (HCC) is the strongest independent predictor of mortality in non-alcoholic steatohepatitis (NASH)-related cirrhosis. The effects and mechanisms of combination of sodium-dependent glucose cotransporter inhibitor and canagliflozin (CA) and dipeptidyl peptidase-4 inhibitor and teneligliptin (TE) on non-diabetic NASH progression were examined. CA and TE suppressed choline-deficient, L-amino acid-defined diet-induced hepatic fibrogenesis and carcinogenesis. CA alone or with TE significantly decreased proinflammatory cytokine expression. CA and TE significantly attenuated hepatic lipid peroxidation. In vitro studies showed that TE alone or with CA inhibited cell proliferation and TGF-β1 and α1 (I)-procollagen mRNA expression in Ac-HSCs. CA+TE inhibited liver fibrogenesis by attenuating hepatic lipid peroxidation and inflammation and by inhibiting Ac-HSC proliferation with concomitant attenuation of hepatic lipid peroxidation. Moreover, CA+TE suppressed in vivo angiogenesis and oxidative DNA damage. CA or CA+TE inhibited HCC cells and human umbilical vein endothelial cell (HUVEC) proliferation. CA+TE suppressed vascular endothelial growth factor expression and promoted increased E-cadherin expression in HUVECs. CA+TE potentially exerts synergistic effects on hepatocarcinogenesis prevention by suppressing HCC cell proliferation and angiogenesis and concomitantly reducing oxidative stress and by inhibiting angiogenesis with attenuation of oxidative stress. CA+TE showed chemopreventive effects on NASH progression compared with single agent in non-diabetic rat model of NASH, concurrent with Ac-HSC and HCC cell proliferation, angiogenesis oxidative stress, and inflammation. Both agents are widely, safely used in clinical practice; combined treatment may represent a potential strategy against NASH.

Abstract
INTRODUCTION Teneligliptin is a dipeptidyl peptidase 4 inhibitor that was approved for the treatment of type 2 diabetes mellitus (T2DM) in Japan in 2012. We performed a long-term post-marketing surveillance (RUBY) to obtain real-world evidence regarding the safety and efficacy of teneligliptin in Japan. METHODS This 3-year follow-up RUBY surveillance registered patients with T2DM who started treatment with teneligliptin between May 2013 and February 2015 in Japan. Collected data included demographics, treatments, adverse drug reactions (ADRs) and laboratory variables. Data were evaluated in all patients and in patients divided according to baseline renal function across categories of estimated glomerular filtration rate (G1-G5) and dialysis. Safety was assessed as the incidence of ADRs and efficacy was assessed in terms of glycaemic control, for up to 3 years. RESULTS Of 11,677 patients registered, 10,696 and 10,249 were evaluable for safety and efficacy analyses, respectively. The median duration of exposure was 1096 days. ADRs occurred in 412 patients (3.85%) and were serious in 117 patients (1.09%). The most frequent ADR class was gastrointestinal disorders (0.68%), which included constipation. There were no new ADRs warranting attention beyond those already described in teneligliptin's package insert. ADRs and serious ADRs in renal function subgroups occurred in 3.24-7.14% and 0.65-5.36% in G1-G5, and 4.49% and 1.92% in patients on dialysis, respectively. Reduction in HbA1c was sustained for 3 years after starting teneligliptin (- 0.70% ± 1.36%, p < 0.001 at 3 years). The least-squares mean changes in HbA1c adjusted for baseline were - 0.76% to - 0.66% in G1-G5 at 3 years. Glycated albumin levels decreased in patients on dialysis (- 2.92% ± 4.78% at 3 years). CONCLUSION There were no new safety or efficacy concerns about teneligliptin used in long-term, real-world, clinical settings in patients with T2DM with any stages of renal impairment.

Abstract
Teneligliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor that was approved for the treatment of type 2 diabetes mellitus (T2DM) in Japan and Korea and is being researched in several countries. Teneligliptin is a potent, selective, and long-lasting DPP-4 inhibitor with a t½ of approximately 24 h and unique pharmacokinetic properties: it is metabolized by cytochrome P450 (CYP) 3A4 and flavin-containing monooxygenase 3 (FMO3), or excreted from the kidney in an unchanged form. Because of its multiple elimination pathways, dose adjustment is not needed in patients with hepatic or renal impairment, and it is considered to have a low potential for drug–drug interactions. Clinical studies and postmarketing surveillance show that teneligliptin, administered as monotherapy and/or in combination with antihyperglycemic agents, is effective and well tolerated in T2DM patients, including in elderly patients and those with renal impairment. Furthermore, teneligliptin has antioxidative properties, which induce the antioxidant cascade, as well as ·OH scavenging properties. In addition, it has shown endothelial protective effects in several non-clinical and clinical studies. From its unique profile and clinical data, teneligliptin represents a potential therapeutic option in a wide variety of patients, including elderly diabetic patients and those with renal impairment. The fixed-dose combination (FDC) tablet of teneligliptin and canagliflozin has been approved in Japan; this is the first FDC tablet of a DPP-4 inhibitor and sodium glucose co-transporter 2 inhibitor in Japan, and the third globally. The FDC tablet may also provide additional prescribing and adherence benefits.

Abstract
OBJECTIVES Despite advances in our understanding of metabolic syndrome (MetS) and the treatment of each of its components separately, currently there is no single therapy approved to manage it as a single condition. Since multi-drug treatment increases drug interactions, decreases patient compliance and increases health costs, it is important to introduce single therapies that improve all of the MetS components. EVIDENCE ACQUISITION We conducted a PubMed, Scopus, Google Scholar, Web of Science, US FDA, utdo.ir and clinicaltrial.gov search, gathered the most relevant preclinical and clinical studies that have been published since 2010, and discussed the beneficial effects of dipeptidyl peptidase (DPP)-4 inhibitors to prevent and treat different constituent of the MetS as a single therapy. Furthermore, the pharmacology of DPP-4 inhibitors, focusing on pharmacodynamics, pharmacokinetics, drug interactions and their side effects are also reviewed. RESULTS DPP-4 inhibitors or gliptins are a new class of oral anti-diabetic drugs that seem safe drugs with no severe side effects, commonly GI disturbance, infection and inflammatory bowel disease. They increase mass and function of pancreatic β-cells, and insulin sensitivity in liver, muscle and adipose tissue. It has been noted that gliptin therapy decreases dyslipidemia. DPP-4 inhibitors increase fatty oxidation, and cholesterol efflux, and decrease hepatic triglyceride synthase and de novo lipogenesis. They delay gastric emptying time and lead to satiety. Besides, gliptin therapy has anti-inflammatory and anti-atherogenic impacts, and improves endothelial function and reduces vascular stiffness. CONCLUSION The gathered data prove the efficacy of DPP-4 inhibitors in managing MetS in some levels beyond anti-diabetic effects. This review could be a lead for designing new DPP-4 inhibitors with greatest effects on MetS in future. Introducing drugs with polypharmacologic effects could increase the patient's compliance and decrease the health cost that there is not in multi-drug therapy. Graphical abstract ᅟ.

Abstract
INTRODUCTION Teneligliptin is a novel oral dipeptidyl peptidase-4 inhibitor for the treatment of type 2 diabetes mellitus (T2DM). Safety and efficacy of teneligliptin have been demonstrated in clinical studies; however, data supporting its use in patients with moderate or severe renal impairment are limited. This interim analysis of a post-marketing surveillance of teneligliptin, exploRing the long-term efficacy and safety included cardiovascUlar events in patients with type 2 diaBetes treated bY teneligliptin in the real-world (RUBY), aims to verify the long-term safety and efficacy of teneligliptin in Japanese patients with T2DM and impaired renal function. METHODS For this analysis, we used the data from case report forms of the RUBY surveillance between May 2013 and June 2017. The patients were classified into G1-G5 stages of chronic kidney disease according to estimated glomerular filtration rate (eGFR) at initiation of teneligliptin treatment. Safety and efficacy were evaluated in these subgroups. Patients on dialysis were also assessed. Safety was assessed from adverse drug reactions (ADRs). Glycemic control was evaluated up to 2 years after teneligliptin initiation. RESULTS A total of 11,677 patients were enrolled in the surveillance and 11,425 patient case-report forms were collected for the interim analysis. The incidence of ADRs in each subgroup was 2.98-6.98% of patients, with no differences in the ADR profile (including hypoglycemia and renal function ADRs) between subgroups. At 1 and 2 years after starting teneligliptin, the least-squares mean change in HbA1c adjusted to the baseline was - 0.68 to - 0.85% and - 0.71 to - 0.85% across the eGFR groups, respectively. Treatment with teneligliptin in patients on dialysis reduced or tended to reduce glycated albumin levels [- 2.29%, (p < 0.001) after 1 year; - 1.64%, (p = 0.064) after 2 years]. CONCLUSIONS During long-term treatment, teneligliptin was generally well tolerated in patients with any stage of renal impairment from normal to end-stage renal disease, including those on dialysis, and improved glycemic control.

Abstract
INTRODUCTION Healthy eating is a critical aspect of the prevention and management of type 2 diabetes (T2DM). Disrupted eating patterns can result in poor glucose control and increase the likelihood of diabetic complications. Teneligliptin inhibits dipeptidyl peptidase-4 activity for 24 h and suppresses postprandial hyperglycemia after all three daily meals. This interim analysis of data from the large-scale post-marketing surveillance of teneligliptin (RUBY) in Japan examined eating patterns and their relationship with metabolic parameters and diabetic complications. We also examined whether eating patterns affected safety and efficacy of teneligliptin. METHODS We analyzed baseline data from survey forms collected in RUBY between May 2013 and June 2017, including patient characteristics, metabolic parameters, and eating patterns (eating three meals per day or not; timing of evening meal) before teneligliptin treatment was initiated. Safety and efficacy of 12 months' teneligliptin (20-40 mg/day) treatment was assessed. RESULTS Data from 10,532 patients were available for analysis. Most patients who did not eat three meals per day (n =757) or who ate their evening meal after 10 PM (n =206) were 64 years old or younger. At baseline, glycated hemoglobin (HbA1c), fasting blood glucose, triglycerides, total and low-density lipoprotein cholesterol, body mass index, alanine aminotransferase, and aspartate aminotransferase levels were higher in those patients who did not eat three meals per day (p < 0.05) or who ate their evening meal late (p < 0.05). Diabetic complications were more common in patients who did not eat three meals per day. Treatment with teneligliptin reduced HbA1c over 6 or 12 months across all eating patterns, with a low incidence of adverse drug reactions. CONCLUSIONS Eating patterns may be associated with altered metabolic parameters and diabetic complications among Japanese patients with T2DM. Teneligliptin may be well tolerated and improve hyperglycemia in patients with T2DM irrespective of eating patterns. FUNDING Mitsubishi Tanabe Pharma Corporation and Daiichi Sankyo Co. Ltd.

Abstract
BACKGROUND The antidiabetic drug teneligliptin is a novel dipeptidyl peptidase-4 (DPP-4) inhibitor with a thiazolidine-specific structure. This study aimed to investigate whether teneligliptin can activate PPARγ directly and/or indirectly in cell-based assays. METHODS Promoter assays using the reporter construct driven under the control of the SV40 promoter and the PPAR response element (PPRE) were performed. Luciferase activity was measured after a 3-day incubation of vector-transduced cells with various concentrations of teneligliptin. RESULTS Treatment of the cells with 50 μM teneligliptin significantly transactivated a reporter gene. The presence of the PPARγ antagonist, GW9662, did not affect the activation of PPRE-reporter expression by teneligliptin. CONCLUSION We found that teneligliptin could increase PPARγ activity in cell-based assays irrespective of the PPARγ ligand-binding domain.

Abstract
Background: Teneligliptin is a 3rd-generation dipeptidyl peptidase-4 (DPP-4) inhibitor. There is a limited evidence regarding the effect of teneligliptin. Therefore, this study is to assess the efficacy and safety of teneligliptin in type 2 diabetes mellitus (T2DM) patients with inadequately glycemic controlled. Methods: A search of PubMed, Medline, Embase, and The Cochrane Library during 2000.01–2018.03 was performed for randomized controlled trials of teneligliptin compared to placebo in patients with T2DM with monotherapy or add-on treatment. Results: Ten trials with 2119 patients were analyzed. Teneligliptin produced absolute reductions in glycated hemoglobin A1c (HbA1c) levels (weighted mean difference (WMD) 0.82%, 95% confidence interval (CI) [−0.91 to −0.72], p < 0.00001) compared with placebo. However, after 36–42 weeks of follow-up (open-label), HbA1c level rise higher than duration (double-blind) in teneligliptin group. Teneligliptin led to greater decrease of fasting plasma glucose (FPG) level (vs. placebo, WMD −18.32%, 95% CI [−21.05 to −15.60], p < 0.00001). Teneligliptin also significantly decreased the 2 h post-prandial plasma glucose (2 h PPG) (WMD −46.94%, 95% CI [−51.58 to −42.30], p < 0.00001) and area under the glucose plasma concentration-time curve from 0 to 2 h (AUC0−2h) for PPG (WMD −71.50%, 95% CI [−78.09 to −64.91], p < 0.00001) compared with placebo. Patients treated with teneligliptin achieved increased homeostasis model assessment of β cell function (HOMA-β) with 9.31 (WMD, 95% CI [7.78–10.85], p < 0.00001). However, there was no significant difference between teneligliptin and placebo in overall adverse effects (0.96 risk ratio (RR), 95% CI [0.87, 1.06], p = 0.06). The risks of hypoglycemia were not significantly different between teneligliptin and placebo (1.16 RR, 95% CI [0.59, 2.26], p = 0.66). Conclusions: Teneligliptin improved blood glucose levels and β-cells function with low risk of hypoglycemia in patients with T2DM. Common adverse effects of teneligliptin including hypoglycemia were identified and reviewed. Risks of cardiovascular events are less certain, and more data for long-term effects are needed.

Abstract
INTRODUCTION Teneligliptin, an antihyperglycemic agent belonging to the dipeptidyl peptidase-4 inhibitor class, is usually prescribed at a dose of 20 mg/day. In Japan, the dose can be increased to 40 mg/day if needed. We examined the treatment response when the teneligliptin dose was increased from 20 to 40 mg in a post hoc pooled analysis of data from two 52-week, open-label, phase III clinical trials of teneligliptin 20-40 mg/day as monotherapy or combination treatment in Japanese patients with type 2 diabetes. METHODS In both studies, patients received teneligliptin 20 mg for at least 28 weeks; thereafter the dose was increased if glycemic control was inadequate. The data set for this post hoc analysis comprised those patients whose teneligliptin dose was increased to 40 mg at week 28 (N = 204). We assessed (i) the proportion of patients achieving HbA1c reduction after teneligliptin dose increase [≤ - 0.1% change in HbA1c during weeks 28-52 (24 weeks); responders] and (ii) the response to teneligliptin 40 mg according to whether or not patients experienced HbA1c re-elevation (≥ 0.1% increase) during 28 weeks of teneligliptin 20 mg. RESULTS Of 204 patients, 108 (52.9%) showed a response to teneligliptin 40 mg (HbA1c change ≤ - 0.1% during weeks 28-52) and had mean (± SD) HbA1c reduction of 0.50 ± 0.44%. Of patients showing re-elevation of HbA1c during treatment with teneligliptin 20 mg, 89/143 (62.2%) achieved HbA1c reduction after dose increase to 40 mg. Logistic regression analyses suggested that change in body weight is one of the parameters linked to HbA1c reduction after dose increase to teneligliptin 40 mg. The incidence of adverse events was not changed after teneligliptin dose increase. CONCLUSION Increasing the dosage of teneligliptin from 20 to 40 mg/day has potential as a well-tolerated and effective option for treating type 2 diabetes.

Abstract
AIM To evaluate the long-term safety and efficacy of canagliflozin as add-on therapy in patients with type 2 diabetes mellitus (T2DM) who had inadequate glycaemic control with teneligliptin monotherapy. METHODS This open-label 52-week study was conducted in Japan. Patients received canagliflozin 100 mg added to teneligliptin 20 mg orally once daily for 52 weeks. The safety endpoint was the incidence of adverse events (AEs). The efficacy endpoints included changes in glycated haemoglobin (HbA1c), fasting plasma glucose (FPG) and body weight from baseline to week 52 (with last observation carried forward). RESULTS Overall, 153 patients entered the treatment period and 142 completed the study. The overall incidence rates of AEs and drug-related AEs were 69.9% and 22.9%, respectively. Most AEs and drug-related AEs were mild or moderate in severity. There were no previously undescribed safety signals. The mean changes in HbA1c, FPG and body weight were -0.99% (95% confidence interval [CI] -1.12 to -0.85), -38.6 mg/dL (95% CI -43.4 to -33.9) and -3.92% (95% CI -4.53 to -3.31), respectively. These effects were maintained for 52 weeks without attenuation. HbA1c and body weight were both decreased in 82.24% of patients at the end of the treatment period. Reductions in postprandial glucose were observed at weeks 24 and 52. CONCLUSIONS No new safety risks with this combination were identified, and sustained improvements in HbA1c, FPG and body weight were observed. The findings suggest that long-term co-administration of canagliflozin with teneligliptin is well tolerated and effective in Japanese patients with T2DM who have inadequate glycaemic control on teneligliptin alone.

Abstract
AIMS This study evaluated the efficacy and safety of teneligliptin in patients with inadequately controlled type 2 diabetes mellitus (T2DM). SETTINGS AND DESIGN This was a randomized, doubleblind, placebocontrolled, parallelgroup, multicenter, Phase III study. SUBJECTS AND METHODS Patients with T2DM and inadequate glycemic control (glycosylated hemoglobin [HbA1c]: >7.0-≤8.5%) were enrolled. Patients were randomly assigned (ratio: 2:1) to receive teneligliptin 20 mg (Glenmark) or placebo. The primary efficacy variable was change from baseline in HbA1c at week 16. Additional analyses included the proportion of patients who achieved target of HbA1c ≤7.0%, changes in fasting plasma glucose (FPG), and postprandial glucose (PPG). STATISTICAL ANALYSIS Mean change in HbA1c was analyzed using an analysis of covariance model, least square (LS) means, 95% confidence intervals (CIs), and P values were calculated. RESULTS Overall, 237 patients were included. Patients of the teneligliptin group showed reduced HbA1c levels (LS mean difference = -0.304% for intent-to-treat [ITT]; -0.291% for per-protocol (PP) populations) after 16 weeks of treatment, and a statistically significant difference was observed between the ITT (LS mean difference = 0.555; 95% CI: 0.176-0.934; P = 0.0043) and PP populations (LS mean difference = 0.642; 95% CI: 0.233-1.052; P = 0.0023). Target HbA1c level was achieved by a greater proportion of teneligliptin group patients (ITT, 43.4%; PP, 43.6%) than placebo group patients (ITT, 27.3%; PP, 26.6%). Reduction in FPG levels was observed in ITT (LS mean difference: 8.829; 95% CI: -4.357-22.016; P = 0.1883) and PP populations (LS mean difference: 11.710 mg/dL; 95% CI: -2.893-26.312; P = 0.1154). Reduction in PPG levels was higher in teneligliptin group than placebo group in both ITT (LS mean difference = 25.849 mg/dL; 95% CI: 7.143-44.556; P = 0.0070) and PP populations (LS mean difference = 25.683 mg/dL; 95% CI: 5.830-45.536; P = 0.0115). Overall, 44 patients (18.6%) experienced at least one adverse event. Three or more hypoglycemic events were experienced by 2.5% patients of teneligliptin group and none in placebo group. CONCLUSION Treatment with once-daily teneligliptin led to statistically significant and clinically meaningful reductions in HbA1c and PPG, and was well tolerated in Indian patients with T2DM.

Abstract
Our purpose was to determine the effects of teneligliptin and sitagliptin, two dipeptidyl peptidase 4 inhibitors (DPP4-Is) with different half-lives, on glycemic variability and glucagon-like peptide-1 (GLP-1) levels in Japanese patients with type 2 diabetes mellitus (T2DM). The study subjects were 14 drug-naïve patients with T2DM who were allocated to either a 20 mg/day teneligliptin group (n = 7) or a 50 mg/day sitagliptin group (n = 7) for 7 days, then switched to the other treatment for another 7 days. Meal tolerance tests were performed at the time of no treatment, and after treatment with each DPP4-Is at supper. We evaluated the effects of each drug on glucose fluctuation using continuous glucose monitoring (CGM). There was no significant difference between the two groups in the primary endpoint (maximum glucose level after supper), nor in the secondary endpoint: area under the curve (AUC) for plasma glucose (≥140 mg/dl) after supper (18:00 - 24:00). Teneligliptin significantly improved the AUC for plasma glucose (≥140 mg/dl) after supper (20:00-24:00) (P = 0.048), and also significantly increased the GLP-1 level at 30 minutes after the meal load (P = 0.030). No serious adverse effects were noted in either group, apart from a few episodes of asymptomatic hypoglycemia. A daily dose of teneligliptin improved the AUC for plasma glucose at 20:00 to 24:00 (≥140 mg/dl) after the meal tolerance test, and also significantly increased the levels of activated GLP-1 after the test meal.

Abstract
AIMS To determine the comparative efficacy and safety of liraglutide and dipeptidyl peptidase-4 (DPP-4) inhibitors as antidiabetics for Japanese patients with uncontrolled type 2 diabetes (T2DM). METHODS AND MATERIALS We searched for randomized controlled trials (RCTs) evaluating outcomes among Japanese adults with uncontrolled T2DM and including liraglutide or DPP-4 inhibitors up to August 2016. We extracted data on trial and patient characteristics, and the following outcomes: HbA1c, weight, patients meeting HbA1c <7%, patients experiencing hypoglycemic events, microalbuminuria, estimated glomerular filtration rate (eGFR) and creatinine. We synthesized data using network meta-analyses (NMA) using a Bayesian framework. Continuous outcomes were modeled using normal likelihoods and an identity link, while dichotomous outcomes were modeled using a binomial likelihood and a logit link. RESULTS The systematic literature review yielded 39 publications pertaining to 38 trials. A total of 27 trials (5032 patients) reported change in HbA1c at 12 weeks and at 24 weeks 9 trials (2091 patients). All treatments showed statistically significant reductions in HbA1c relative to placebo at 12 and 24 weeks. Liraglutide 0.9 mg was statistically superior to all DPP-4 interventions (vildagliptin, sitagliptin, linagliptin, alogliptin, teneligliptin, trelagliptin and omarigliptin) at 12 weeks and 24 weeks among those reporting. Treatments were not statistically differentiable with respect to weight change and risk of hypoglycemia. Finally, no comparisons of eGFR and microalbuminuria were conducted, as this data was reported in too few trials to conduct analyses. LIMITATIONS Some important outcomes were limited by poor reporting (eGFR and microalbuminuria) or low event rates (hypoglycemia). The follow-up time was relatively short. Clinically, the 24 week time point is more important as it demonstrates more sustained results. CONCLUSIONS Our research suggests that liraglutide 0.9 mg offers a more efficacious treatment option for T2DM than the DPP-4 inhibitors among adult Japanese patients and that it is a viable option for this population.

Abstract
AIMS To investigate efficacy and safety of the sodium-glucose co-transporter 2 (SGLT2) inhibitor canagliflozin administered as add-on therapy to the dipeptidyl peptidase-4 (DPP-4) inhibitor teneligliptin in patients with type 2 diabetes mellitus (T2DM). MATERIALS AND METHODS We conducted a multicentre, randomized, double-blind, placebo-controlled, phase 3 clinical trial in Japanese patients with T2DM who had inadequate glycaemic control with teneligliptin. Patients were randomized to receive teneligliptin 20 mg plus either canagliflozin 100 mg (T + C, n = 70) or placebo (T + P, n = 68) once daily. The primary endpoint was the change in glycated haemoglobin (HbA1c) from baseline to week 24. Other endpoints included changes in fasting plasma glucose, body weight, proinsulin/C-peptide ratio, homeostatic model assessment 2-%B and adverse events. Patients also underwent mixed-meal tolerance tests. RESULTS The difference between the T + C and T + P groups for HbA1c change from baseline to week 24 was -0.88% (least-squares mean, P < .001). Fasting plasma glucose, body weight and the proinsulin/C-peptide ratio were significantly lower in the T + C group than in the T + P group. Homeostatic model assessment 2-%B improved with T + C compared with T + P. The T + C group exhibited a decrease in the 2-hour postprandial plasma glucose and plasma glucose area under the curve (AUC)0-2h in a mixed-meal tolerance test. No significant between-group differences were observed for C-peptide AUC0-2h or glucagon AUC0-2h after meals. Incidences of adverse events were 60.0% and 47.1% in the T + C and T + P groups, respectively. No hypoglycaemia was observed. CONCLUSIONS Canagliflozin administered as add-on therapy to teneligliptin was effective and well tolerated in Japanese T2DM patients.

Abstract
BACKGROUND Large randomized trials have shown conflicting evidence regarding the cardiovascular safety of dipeptidyl-peptidase 4 (DPP-4) inhibitors. Systematic reviews have been limited by incomplete data and inclusion of observational studies. This study aimed to systematically evaluate the cardiovascular safety of DPP-4 inhibitors in patients with type 2 diabetes. METHODS Electronic databases were searched for randomized trials that compared DPP-4 inhibitors versus placebo and reported cardiovascular outcomes. The main outcome assessed in this analysis was heart failure. Other outcomes included all-cause mortality, cardiovascular mortality, myocardial infarction, and ischemic stroke. Summary odds ratios (ORs) were primarily constructed using Peto's model. RESULTS A total of 90 trials with 66,730 patients were included. Compared with placebo, DPP-4 inhibitors were associated with a non-significant increased risk of heart failure [OR 1.11, 95% confidence interval (CI) 0.99-1.25, P = 0.07] at a mean of 108 weeks. The risk of all-cause mortality (OR 1.03, 95% CI 0.94-1.12, P = 0.53), cardiovascular mortality (OR 1.02, 95% CI 0.92-1.14, P = 0.72), myocardial infarction (OR 0.98, 95% CI 0.88-1.09, P = 0.69), and ischemic stroke (OR 0.99, 95% CI 0.85-1.15, P = 0.92) was similar between both groups. CONCLUSION In patients with type 2 diabetes, the safety profile of DPP-4 inhibitors is similar to placebo. As a class, there is only weak evidence for an increased risk of heart failure.

Abstract
BACKGROUND AND AIMS Teneligliptin was introduced in India in May 2015. It has gained popularity and is already widely prescribed in type 2 diabetes mellitus (T2DM). This "real life" data collection was conducted to assess the efficacy of teneligliptin in Indian T2DM patients. METHODS Predesigned structured proforma was used to collect information from the prescribing physicians regarding the efficacy of teneligliptin when prescribed as monotherapy as well as combination therapy with other antidiabetic drugs in T2DM patients. Information on the glycemic parameters at baseline prior to starting teneligliptin and at the end of 3 months therapy was collected. The efficacy was assessed by analyzing the mean change in 3-month values of glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG), and postprandial plasma glucose (PPG). RESULTS Data of 4305 patients was available for analysis. There was statistically significant improvement in mean HbA1c, FPG, and PPG with teneligliptin therapy. Means changes in HbA1c, FPG, and PPG were -1.37%±1.15%, 51.29±35.41 mg/dL, and 80.89±54.27 mg/dL, respectively. Subgroup analysis revealed that HbA1c (%) reduction with teneligliptin when used as monotherapy, add-on to metformin or add-on to metformin plus sulfonylureas combination, add-on to metformin plus alpha glucosidase inhibitor combination or add-on to insulin was 0.98±0.53, 1.07±0.83, 1.46±1.33, 1.43±0.80, and 1.55±1.05, respectively. CONCLUSION Real-world data suggests that teneligliptin significantly improves glycemic control in Indian patients with T2DM when prescribed either as monotherapy or as an add-on to one or more other commonly prescribed antidiabetic drugs.

Abstract
AIMS/HYPOTHESIS Recently, incretin-related agents have been reported to attenuate insulin resistance in animal models, although the underlying mechanisms remain unclear. In this study, we investigated whether anagliptin, the dipeptidyl peptidase 4 (DPP-4) inhibitor, attenuates skeletal muscle insulin resistance through endothelial nitric oxide synthase (eNOS) activation in the endothelial cells. We used endothelium-specific Irs2-knockout (ETIrs2KO) mice, which show skeletal muscle insulin resistance resulting from a reduction of insulin-induced skeletal muscle capillary recruitment as a consequence of impaired eNOS activation. METHODS In vivo, 8-week-old male ETIrs2KO mice were fed regular chow with or without 0.3% (wt/wt) DPP-4 inhibitor for 8 weeks to assess capillary recruitment and glucose uptake by the skeletal muscle. In vitro, human coronary arterial endothelial cells (HCAECs) were used to explore the effect of glucagon-like peptide 1 (GLP-1) on eNOS activity. RESULTS Treatment with anagliptin ameliorated the impaired insulin-induced increase in capillary blood volume, interstitial insulin concentration and skeletal muscle glucose uptake in ETIrs2KO mice. This improvement in insulin-induced glucose uptake was almost completely abrogated by the GLP-1 receptor (GLP-1R) antagonist exendin-(9-39). Moreover, the increase in capillary blood volume with anagliptin treatment was also completely inhibited by the NOS inhibitor. GLP-1 augmented eNOS phosphorylation in HCAECs, with the effect completely disappearing after exposure to the protein kinase A (PKA) inhibitor H89. These data suggest that anagliptin treatment enhances insulin-induced capillary recruitment and interstitial insulin concentrations, resulting in improved skeletal muscle glucose uptake by directly acting on the endothelial cells via NO- and GLP-1-dependent mechanisms in vivo. CONCLUSIONS/INTERPRETATION Anagliptin may be a promising agent to ameliorate skeletal muscle insulin resistance in obese patients with type 2 diabetes.

Abstract
Teneligliptin is a recently developed oral dipeptidyl peptidase 4 inhibitor indicated for the management of type 2 diabetes mellitus (T2DM) in adults along with diet and exercise. Teneligliptin has been recently available in Japan (Teneria(®)), Argentina (Teneglucon(®)), and India (Tenepure; Teneza) at relatively affordable price. This is a positive step toward the management of T2DM in developing countries, where the cost of medicine is out-of-pocket expenditure and is a limiting factor for health care. This review evaluates the efficacy and safety of teneligliptin in the management of T2DM. Teneligliptin has been systematically evaluated in T2DM as monotherapy with diet and exercise and in combination with metformin, glimepiride, pioglitazone, and insulin in short-term (12 weeks) and long-term (52 weeks) studies. These studies have reported a reduction in HbA1c of 0.8%-0.9% within 12 weeks of therapy. Two 52-week studies reported sustained improvement in glycemic control with teneligliptin. Teneligliptin has been found to be well tolerated, and the safety profile is similar to other dipeptidyl peptidase 4 inhibitors. Hypoglycemia and constipation are the main adverse events. Teneligliptin can be administered safely to patients with mild, moderate, or severe renal impairment or end-stage renal disease without dose adjustment. Similarly, it can be used in patients with mild-to-moderate hepatic impairment. Teneligliptin is effective and well tolerated and may have an important role in the management of T2DM.

Abstract
Oral teneligliptin [Teneglucon® (Argentina)], a dipeptidyl peptidase-4 inhibitor, is indicated for the treatment of adults with type 2 diabetes (T2DM). This article reviews the pharmacology, therapeutic efficacy and tolerability of teneligliptin in the treatment of adults with T2DM. In 12- or 16-week, placebo-controlled phase 2 and 3 trials, oral teneligliptin 20 or 40 mg once daily, as monotherapy or in combination with metformin, glimepiride or pioglitazone improved glycaemic control, including in patients with end-stage renal disease, and was generally well tolerated. Most treatment-emergent adverse events were of mild intensity and relatively few patients discontinued treatment because of these events. Improvements in glycaemic control observed in short-term trials were maintained at 52 weeks in extension phases of these trials and in 52-week interventional studies, with no new safety concerns identified during this period. In the absence of direct head-to-head clinical trials, the position of teneligliptin relative to other antidiabetic agents in the management of T2DM remains to be determined. In the meantime, teneligliptin is a useful treatment option for adults with T2DM who have not responded adequately to diet and exercise regimens, or the addition of antidiabetic drugs.

Abstract
Introduction It remains unknown whether dipeptidyl peptidase-4 (DPP-4) inhibitors improve early-phase insulin secretion in Japanese patients with type 2 diabetes (T2D), a disease characterized by impaired insulin secretion. We investigated the changes in insulin secretion before and after treatment with the DPP-4 inhibitor teneligliptin in patients with T2D with a low insulinogenic index (IGI) determined by the oral glucose tolerance test (OGTT). Methods An open-label, prospective clinical study was conducted. Thirteen drug-naïve patients (mean age 55.5 ± 3.9 years) with T2D underwent OGTT before and after teneligliptin 20 mg/day monotherapy. Plasma levels of glucose (PG), insulin, and C-peptide were measured at 0, 30, 60, 90, and 120 min after glucose loading in the OGTT. Homeostasis model assessment (HOMA)-β, IGI, and the total or incremental area under the curve (AUC) for PG and insulin were measured. AUC120min for the secretory units of islets in transplantation (SUIT) index was also measured. Results HbA1c significantly decreased from 8.3 ± 0.4 % at baseline to 6.3 ± 0.2 % after 12 weeks of teneligliptin treatment (p < 0.05). Incremental AUC120min PG also significantly decreased, and β-cell function assessed by IGI30min, AUC120min insulin, and the AUC120min SUIT index significantly increased (0.16 ± 0.05 vs. 0.28 ± 0.06, 2692 ± 333 µU·2h/mL vs. 3537 ± 361 µU·2h/mL, and 4261 ± 442 vs. 8290 ± 1147, respectively; all p < 0.05). HOMA-β was unchanged. The reduction in incremental AUC120min PG was significantly associated with the augmentation of IGI30min and the AUC120min SUIT index. No severe adverse events were observed. Conclusions Twelve weeks of teneligliptin treatment improved IGI30min, AUC120min, and the SUIT index in drug-naïve Japanese patients with T2D.

Abstract
OBJECTIVE The study investigated the efficacy and tolerability of teneligliptin co-administered to patients with type 2 diabetes mellitus (T2DM) who were inadequately controlled by stable metformin monotherapy ≥ 1000 mg/day. METHODS A total of 447 patients from 55 European centers who completed a 14-day screening and 14-day run-in phase, received randomized double-blind treatment with 5, 10, 20 or 40 mg teneligliptin or placebo once daily, for 24 weeks. 364 patients continued treatment in a 28-week open label extension during which they received teneligliptin 20 mg once daily. RESULTS Co-administration of teneligliptin (5 to 40 mg) with metformin demonstrated dose-related and statistically significant reductions in HbA1c after 24 weeks (-0.30 to -0.63% placebo adjusted) of double-blind treatment. The greatest reduction in HbA1c was seen with teneligliptin at 40 mg (-0.63%) at Week 24. There was also a dose-dependent increase in proportion of responders achieving HbA1c < 7.0% at this endpoint. Responses were maintained throughout 28 weeks open label treatment with 20 mg teneligliptin. Treatment was well tolerated to Week 52 and the overall incidence of hypoglycemia during 52 weeks was 2.3%. CONCLUSIONS Teneligliptin co-administered with metformin produced significant reductions in HbA1c in patients with T2DM without increasing the risk of hypoglycemia.

Abstract
We assessed the 24-week efficacy and safety of teneligliptin, a novel dipeptidyl peptidase-4 inhibitor, in Korean patients with type 2 diabetes mellitus (T2DM) that was inadequately controlled with diet and exercise. The present study was designed as a multicentre, randomized, double-blind, placebo-controlled, parallel-group, phase III study. Patients (n = 142) were randomized 2 : 1 into two different treatment groups as follows: 99 received teneligliptin (20 mg) and 43 received placebo. The primary endpoint was change in glycated haemoglobin (HbA1c) level from baseline to week 24. Teneligliptin significantly reduced the HbA1c level from baseline compared with placebo after 24 weeks. At week 24, the differences between changes in HbA1c and fasting plasma glucose (FBG) in the teneligliptin and placebo groups were -0.94% [least-squares (LS) mean -1.22, -0.65] and -1.21 mmol/l (-1.72, -0.70), respectively (all p < 0.001). The incidence of hypoglycaemia and adverse events were not significantly different between the two groups. This phase III, randomized, placebo-controlled study provides evidence of the safety and efficacy of 24 weeks of treatment with teneligliptin as a monotherapy in Korean patients with T2DM.

Abstract
The traditional oral pharmacological therapy for type 2 diabetes mellitus (T2DM) has been based on the prescription of metformin, a biguanide, as first line antihyperglycemic agent world over. It has been demonstrated that after 3 years of treatment, approximately 50 % of diabetic patients could achieve acceptable glucose levels with monotherapy; but by 9 years this had declined to only 25 %. Therefore, the implementation of a combined pharmacological therapy acting via different pathways becomes necessary, and its combination with a compound of the sulfonylurea group was along decades the most frequently employed prescription in routine clinical practice. Meglitinides, glitazones and alpha-glucosidase inhibitors were subsequently developed, but the five mentioned groups of oral antihyperglycemic agents are associated with variable degrees of undesirable or even severe cardiovascular events. The gliptins—also called dipeptidyl peptidase 4 (DPP4) inhibitors—are an additional group of antidiabetic compounds with increasing clinical use. We review the status of the gliptins with emphasis on their capabilities to positively or negatively affect the cardiovascular system, and their potential involvement in major adverse cardiovascular events (MACE). Alogliptin, anagliptin, linagliptin, saxagliptin, sitagliptin, teneligliptin and vildagliptin are the compounds currently in clinical use. Regardless differences in chemical structure and metabolic pathways, gliptins as a group exert favorable changes in experimental models. These changes, as an almost general rule, include improved endothelial function, reduction of inflammatory markers, oxidative stress ischemia/reperfusion injury and atherogenesis. In addition, increased adiponectin levels and modest decreases in lipidemia and blood pressure were reported. In clinical settings, several trials—notably the longer one, employing sitagliptin, with a mean follow-up period of 3 years—did not show an increased risk for ischemic events. Anyway, it should be emphasized that the encouraging results from basic science were not yet translated into clinical evidence, probably due the multiple and pleiotropic enzymatic effects of DPP4 inhibition. Moreover, when employing saxagliptin, while the drug was not associated with an augmented risk for ischemic events, it should be pinpointed that the rate of hospitalization for heart failure was significantly increased. Gliptins as a group constitute a widely accepted therapy for the management of T2DM, usually as a second-line medication. Nonetheless, for the time being, a definite relationship between gliptins treatment and improved cardiovascular outcomes remains uncertain and needs yet to be proven.

Abstract
BACKGROUND This study aimed to evaluate the effect of sitagliptin, an oral dipeptidyl peptidase-4 inhibitor, on insulin secretion and glucagon suppression in Korean subjects with type 2 diabetes mellitus. METHODS Twenty-four subjects underwent a 75-g oral glucose tolerance test (OGTT) before and after 6 months of sitagliptin treatment. Sitagliptin, insulin, and sulfonylurea were withdrawn for 3 days before OGTT to eliminate any acute effects on β-cell insulin or α-cell glucagon secretion. Venous samples were drawn five times during each OGTT to measure plasma glucose, insulin, and glucagon. Indices on insulin secretion and resistance were calculated. RESULTS Early phase insulin secretion, measured by the insulinogenic index significantly increased after 6 months of sitagliptin treatment, especially in the higher baseline body mass index group and higher baseline glycosylated hemoglobin (HbA1c) group. There were no significant differences in the insulin resistance indices before and after sitagliptin treatment. Although no significant differences were observed in the absolute levels of glucagon and the glucagon-to-insulin ratio, there was a significant reduction in the percentile change of glucagon-to-insulin ratio at 30- and 120-minute during the OGTT. CONCLUSION Although the HbA1c level did not decrease significantly after 6 months of sitagliptin treatment, an increase in insulin secretion and reduction in early phase postprandial plasma glucagon-to-insulin ratio excursion was confirmed in Korean subjects with type 2 diabetes.

Abstract
INTRODUCTION The main aim in the management of diabetes mellitus is to prevent the development of its complications. Large fluctuations in glucose levels may increase the risk of complications, so improved control of glucose fluctuations, in addition to management of chronic hyperglycemia, could represent an important goal in diabetes pharmacotherapy. AREAS COVERED Pre-clinical and clinical studies suggest that poor control of blood glucose fluctuations contributes to progression of diabetic vascular complications. Dipeptidyl peptidase (DPP)-4 inhibitors are one of several drug classes used to manage diabetes, and the potential vasoprotective effects of DPP-4 inhibition have attracted attention in recent years. The DPP-4 inhibitor teneligliptin was approved in Japan in 2012 and in Korea in 2014. Teneligliptin differs in its structural and pharmacokinetic characteristics compared with other drugs in the same class. It appears to have potent, sustained effects on glycemic control, thereby reducing the complications of hypoglycemia and postprandial hyperglycemia. Because of its effects on vascular function, teneligliptin may be beneficial in patients at high risk of cardiovascular disease. EXPERT OPINION The possible pleiotropic effects of teneligliptin, such as those on endothelial function and metabolic syndrome, are of great interest. This review examines these effects and their potential clinical relevance.

Abstract
OBJECTIVE To assess the safety and efficacy of long-term administration of teneligliptin alone and in combination with oral antidiabetic drugs in Japanese type 2 diabetes mellitus (T2DM) patients with insufficient glycemic control. METHODS This post-hoc pooled analysis used data from two Phase III clinical studies involving 702 Japanese patients. We evaluated teneligliptin as monotherapy and combined with a sulfonylurea, glinide, biguanide, or α-glucosidase inhibitor. Safety measures included adverse events (AEs), adverse reactions and hypoglycemia. The main efficacy measure was the change in glycated hemoglobin (HbA1c) from baseline. RESULTS Incidences of AEs and adverse reactions were similar among the teneligliptin monotherapy group and all combination therapy groups except the combination with sulfonylurea. Hypoglycemia was more frequent in the sulfonylurea combination therapy group than in other groups. Teneligliptin administered once daily as monotherapy or combination therapy resulted in a decrease in HbA1c, which was maintained for 52 weeks. Bodyweight showed no change or a slight increase at the end of 52 weeks in all groups. CONCLUSIONS This pooled analysis provides evidence for the safety and efficacy of long-term use of teneligliptin as monotherapy or combination therapy in Japanese T2DM patients.

Abstract
The aim of the present study was to assess the efficacy and safety of teneligliptin in combination with metformin in Korean patients with type 2 diabetes mellitus who were inadequately controlled with metformin monotherapy. Patients [glycated haemoglobin (HbA1c) 7.0-10.0%, on stable metformin ≥1000 mg/day] were randomized 2 : 1 to receive 20 mg teneligliptin plus metformin (n = 136) or placebo plus metformin (n = 68). The primary endpoint was the change in HbA1c levels from baseline to week 16. The mean baseline HbA1c was 7.9% in the teneligliptin group and 7.8% in the placebo group. The differences between the teneligliptin and placebo groups regarding changes in HbA1c and fasting plasma glucose levels were -0.78 % and -1.24 mmol/l (22.42 mg/dl), respectively, at week 16. The incidence of adverse events was similar between the groups. The addition of teneligliptin once daily to metformin was effective and generally well tolerated in Korean patients with type 2 diabetes.

Abstract
Teneligliptin is a type 2 diabetes drug that has an inhibitory effect on dipeptidyl peptidase-4. The aim of this study was to establish a physiologically based pharmacokinetic (PBPK) model to elucidate in detail the pharmacokinetics of teneligliptin. A PBPK model of teneligliptin was developed using the population-based Simcyp simulator incorporating the results of in vitro and in vivo studies. Model validation was conducted by comparison of simulated teneligliptin plasma concentrations with those from clinical trials. Using the PBPK model, predicted drug-drug interactions with concomitant medication were examined. The robustness of the PBPK model was demonstrated by the accurate simulation of clinically measured plasma concentrations of teneligliptin after oral administration in different ethnic groups, in subjects belonging to different age groups and in patients with kidney or liver impairment; none of these factors were incorporated during model development. The fraction absorbed and intestinal availability of teneligliptin predicted by the model were 0.62 and 0.99, respectively. The predicted ratios of areas under the time-concentration curves (AUCs) in patients with moderate and severe renal impairment who were concomitantly administered ketoconazole, a potent inhibitor of P450 3A4, were, respectively, 2.1- and 2.2-fold those in healthy adults who were given teneligliptin alone. A robust PBPK model reflecting the pharmacokinetic properties of teneligliptin was constructed. The final optimized PBPK model enabled us to elucidate in detail the factors affecting the pharmacokinetics of teneligliptin and to predict changes in exposure in drug-drug interactions or in specific populations.

Abstract
Teneligliptin is a novel peptidomimetic-chemotype prolylthiazolidine-based inhibitor of dipeptidyl peptidase-4 (DPP-4). The aim of this study was to evaluate the effects of teneligliptin on 24 h blood glucose control and gastrointestinal hormone responses to a meal tolerance test, and to investigate the glucose-lowering mechanisms of teneligliptin. Ten patients with type 2 diabetes mellitus (T2DM) were treated for 3 days with teneligliptin (20 mg/day). Postprandial profiles for glucose, insulin, glucagon, active glucagon-like peptide-1 (GLP-1), active glucose-dependent insulinotropic polypeptide (GIP), ghrelin, des-acyl ghrelin, and 24 h glycemic fluctuations were measured via continuous glucose monitoring for 4 days. Once daily teneligliptin administration for 3 days significantly lowered postprandial and fasting glucose levels. Significant elevations of fasting and postprandial active GLP-1 and postprandial active GIP levels were observed. Teneligliptin lowered postprandial glucose elevations, 24 h mean blood glucose levels, standard deviation of 24 h glucose levels and mean amplitude of glycemic excursions (MAGE) without hypoglycemia. Serum insulin levels in the fasting state and 30 min after a meal were similar before and after teneligliptin treatment; however significant reductions at 60 to 180 min after treatment were observed. A significant elevation in early-phase insulin secretion estimated by insulinogenic and oral disposition indices, and a significant reduction in postprandial glucagon AUC were observed. Both plasma ghrelin and des-acyl ghrelin levels were unaltered following teneligliptin treatment. Teneligliptin improved 24 h blood glucose levels by increasing active incretin levels and early-phase insulin secretion, reducing the postprandial insulin requirement, and reducing glucagon secretion. Even short-term teneligliptin treatment may offer benefits for patients with T2DM.

Abstract
OBJECTIVES To investigate the pharmacokinetic/pharmacodynamic interactions of the antidiabetic agents canagliflozin (a sodium-glucose cotransporter-2 inhibitor) and teneligliptin (a dipeptidyl peptidase-4 inhibitor) in Japanese healthy adult men. METHODS Open-label, one-way crossover study used canagliflozin (200 mg/day p.o.) and teneligliptin (40mg/day p.o). A single dose of object drug (either canagliflozin or teneligliptin) was administered on day 1 followed by washout and continuous administration of precipitant drug (days 1 - 9). Both drugs were concomitantly administered on day 7. RESULTS No changes in AUC0 - 72h and Cmax were observed for canagliflozin+teneligliptin versus monotherapy; geometric mean ratios for AUC0 - 72h and Cmax were 0.982 and 0.982 for the plasma concentration of canagliflozin and 0.983 and 0.976 for the plasma concentration of teneligliptin, respectively. Plasma concentrations of active and total glucagon-like peptide-1 (GLP-1) increased with canagliflozin+teneligliptin versus teneligliptin alone. Mean AUC0.5 - 4h increased post-meal, on combination therapy, from 9.6 to 12.5 pmol·h/l (active GLP-1) and from 21.5 to 32.3 pmol·h/l (total GLP-1). Adverse events developed in four subjects; all were mild and resolved but one subject withdrew due to generalized erythema. CONCLUSIONS GLP-1 levels increased with the canagliflozin+teneligliptin combination, and no PK interaction was observed. This combination may show favorable antidiabetic effects without increasing systemic exposure.

Abstract
The half life (t1/2 ) of teneligliptin is 24.2 hours. Accordingly, we hypothesized that the administration of teneligliptin every other day might improve glycemic control. In this study, we evaluated the effectiveness of the administration of teneligliptin every other day in Japanese patients with type 2 diabetes. Fifty-one patients were randomly assigned to receive treatment with 20 mg of teneligliptin every day (Group A) or 20 mg of teneligliptin every other day (Group B) for 12 weeks. HbA1c, glycoalbumin (GA), 1,5-anhydroglucitol (1,5-AG), lipid, blood pressure, body weight, urine albumin-to-creatinine ratio, overall treatment satisfaction level, adverse events and drug adherence were all measured. Forty-seven patients completed this study, and the HbA1c, GA, and 1,5-AG levels in group B were found to be decreased to the same extent as those in group A. No distinct differences in the overall treatment satisfaction level, adverse events, or drug adherence were seen between the two groups at 12 weeks. The administration of teneligliptin every other day had a similar efficacy, patient satisfaction level, and safety compared with its administration every day. This information will be useful for reducing the economic load without changing the patients' satisfaction and glycemic control.

Abstract
BACKGROUND The effects of the mitiglinide/voglibose fixed-dose combination on postprandial glycemic/metabolic responses in patients with type 2 diabetes mellitus (T2DM) treated with dipeptidyl peptidase-4 (DPP-4) inhibitors are unknown. METHODS Twelve T2DM patients treated with a DPP-4 inhibitor underwent identical meal tolerance tests (MTTs) at breakfast, lunch and dinner, before and 2 - 3 weeks after treatment with a fixed-dose combination of mitiglinide 10 mg and voglibose 0.2 mg (combination). Patients were randomized in a cross-over fashion to administer the combination either three-times-daily before each meal or twice-daily before breakfast and dinner. Glycemic/metabolic responses were evaluated at 0, 30, 60 and 120 min in each MTT. RESULTS Three-times-daily administration of the combination significantly suppressed postprandial hyperglycemia after each meal, particularly after lunch and dinner. Active glucagon-like peptide-1 levels increased significantly after each meal, as did early-phase insulin secretion without excessive insulin secretion. Postprandial hyperglycemia after lunch was significantly greater after twice-daily than three-times-daily administration, but there were no clinically relevant differences in other metabolic responses. CONCLUSION This study revealed that adding the mitiglinide/voglibose combination to a DPP-4 inhibitor elicited additive improvements in postprandial glycemic/metabolic responses assessed using MTTs at breakfast, lunch and dinner with identical meal compositions.

Efficacy and safety of teneligliptin added to glimepiride in Japanese patients with type 2 diabetes mellitus: a randomized, double-blind, placebo-controlled study with an open-label, long-term extension. Diabetes Obes Metab 2014; 16:418-25. [PMID: 24205974 DOI: 10.1111/dom.12235] [Citation(s) in RCA: 43] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2013] [Revised: 06/19/2013] [Accepted: 11/02/2013] [Indexed: 12/01/2022]
Abstract
AIMS To assess the efficacy and safety of teneligliptin in combination with glimepiride in Japanese patients with type 2 diabetes mellitus (T2DM) inadequately controlled with glimepiride monotherapy. METHODS In the initial 12-week, double-blind, placebo-controlled, parallel-group period, 194 patients [haemoglobin A1c (HbA1c): 8.4 ± 0.8%; fasting plasma glucose (FPG): 164.2 ± 28.1 mg/dl] were randomized to either teneligliptin 20 mg or placebo once daily while continuing stable glimepiride therapy. This randomized period was then followed by a 40-week, open-label period, where all patients received teneligliptin once daily. The primary endpoint was the change in HbA1c from baseline to week 12. RESULTS Teneligliptin reduced HbA1c significantly compared with placebo at week 12. The placebo-subtracted change in HbA1c was -1.0 ± 0.1% [least-squares (LS) mean ± s.e., p < 0.001]. Teneligliptin also significantly reduced FPG and 2-h postprandial glucose (PPG) as compared with placebo at week 12; the placebo-subtracted changes were -27.1 ± 3.2 and -49.1 ± 6.2 mg/dl (LS mean ± s.e., both p < 0.001), respectively. The blood glucose-lowering effects were sustained throughout the 40-week open-label period. The incidence rates of adverse events and adverse drug reactions, including hypoglycaemia, during the double-blind randomized period were similar in both groups. Therefore, teneligliptin was generally well tolerated when used in combination with glimepiride. CONCLUSIONS The addition of teneligliptin was effective and generally well tolerated in Japanese patients with T2DM inadequately controlled with glimepiride monotherapy. The improvements in glycaemic control were maintained for up to 52 weeks.

Effect of ketoconazole on the pharmacokinetics of the dipeptidyl peptidase-4 inhibitor teneligliptin: an open-label study in healthy white subjects in Germany. Clin Ther 2014; 36:760-9. [PMID: 24726088 DOI: 10.1016/j.clinthera.2014.03.002] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2013] [Revised: 02/21/2014] [Accepted: 03/07/2014] [Indexed: 02/06/2023]
Abstract
OBJECTIVE The aim of this study was to examine the effect of ketoconazole, a potent cytochrome P450 (CYP) 3A4 and P-glycoprotein (P-gp) inhibitor, on teneligliptin pharmacokinetics and to evaluate the safety of combined administration of teneligliptin with ketoconazole. METHODS This open-label, fixed-sequence study was conducted in 16 healthy adult volunteers in Germany. On day 1, under fasting conditions, 20 mg of teneligliptin was administered to evaluate the pharmacokinetics of teneligliptin alone. For 3 days (days 8-10), 400 mg of ketoconazole was administered once daily. On day 11, teneligliptin 20 mg and ketoconazole 400 mg were concurrently administered, and for 2 days (days 12 and 13), ketoconazole was administered once daily. The pharmacokinetic parameters (Cmax, Tmax, AUC, terminal t½, apparent total plasma clearance, and Vd during the terminal phase) of teneligliptin on days 1 and 11 were calculated. The safety profile was evaluated based on adverse events and clinical findings. To investigate the role of human P-gp in membrane permeation of teneligliptin, an in vitro study was performed to measure the transcellular transport of teneligliptin across monolayers of human P-gp-expressing cells and control cells. RESULTS For Cmax and AUC, the geometric least squares mean ratios (90% CIs) of teneligliptin with ketoconazole to teneligliptin alone were 1.37 (1.25-1.50) and 1.49 (1.39-1.60), respectively. There was no change in t½ of the terminal elimination phase. In addition, the tolerability of teneligliptin coadministered with ketoconazole was acceptable. The in vitro study revealed corrected efflux ratios for teneligliptin of 6.81 and 5.27 at teneligliptin concentrations of 1 and 10 μM, respectively. CONCLUSIONS Because the exposure to teneligliptin in combined administration with ketoconazole, a potent CYP3A4 and P-gp inhibitor, was less than twice that of administration of teneligliptin alone, it is suggested that combined administration of teneligliptin with drugs and foods that inhibit CYP3A4 should not cause a marked increase in exposure. The results of our in vitro study suggest that teneligliptin is a substrate of P-gp. CLINICAL TRIAL REGISTRATION EudraCT No. 2009-016652-51.

Abstract
BACKGROUND Meal tolerance tests (MTTs) are usually conducted at breakfast after overnight fasting in type 2 diabetes mellitus (T2DM) patients, but differences in postprandial glycemic responses between meals have been reported. OBJECTIVE We conducted MTTs at breakfast, lunch, and dinner to examine the effects of a fixed combination of 10 mg mitiglinide/0.2 mg voglibose (the combination) on glycemic/metabolic responses to meals during the day in T2DM patients. MTTs with unified meals were conducted in 11 T2DM patients before and after 4 weeks of treatment with the combination administered thrice daily before meals. Glycemic/metabolic profiles measured before and at 30, 60, and 120 min after each meal were compared between each meal and between the baseline and treatment periods. RESULTS AND CONCLUSION The combination significantly reduced postprandial hyperglycemia after each meal. Postprandial AUC0 - 120 min for insulin significantly decreased after lunch and dinner compared with after breakfast, while insulin levels significantly increased at only 30 min after breakfast and dinner. The combination also significantly increased postprandial C-peptide and active glucagon-like peptide-1 levels, and reduced free fatty acid and triglyceride levels, but did not significantly affect glucagon levels compared with baseline, confirming that treatment with the combination improves postprandial responses in Japanese T2DM patients.

The novel dipeptidyl peptidase-4 inhibitor teneligliptin prevents high-fat diet-induced obesity accompanied with increased energy expenditure in mice. Eur J Pharmacol 2013; 723:207-15.

Abstract
Dipeptidyl peptidase-4 (DPP-4)-deficient mice exhibit prevention of obesity with increased energy expenditure, whereas currently available DPP-4 inhibitors do not induce similar changes. We investigated the impact of the novel DPP-4 inhibitor teneligliptin on body weight, energy expenditure, and obesity-related manifestations in diet-induced obese mice. Six-weeks-old C57BL/6N mice were fed a high-fat diet (60%kcal fat) ad libitum and administered teneligliptin (30 or 60mg/kg) via drinking water for 10 weeks. Mice fed a high-fat diet showed accelerated body weight gain. In contrast, compared with the vehicle group, the administration of teneligliptin reduced body weight to 88% and 71% at dose of 30mg/kg/day and 60mg/kg/day, respectively. Although there was no change in locomotor activity, indirect calorimetry studies showed that teneligliptin (60mg/kg) increased oxygen consumption by 22%. Adipocyte hypertrophy and hepatic steatosis induced by a high-fat diet were suppressed by teneligliptin. The mean adipocyte size in the 60-mg/kg treatment group was 44% and hepatic triglyceride levels were 34% of the levels in the vehicle group. Furthermore, treatment with teneligliptin (60mg/kg) reduced plasma levels of insulin to 40% and increased the glucose infusion rate to 39%, as measured in the euglycemic clamp study, indicating its beneficial effect on insulin resistance. We showed for the first time that the DPP-4 inhibitor prevents obesity and obesity-related manifestations with increased energy expenditure. Our findings suggest the potential utility of teneligliptin for the treatment of a broad spectrum of metabolic disorders related to obesity beyond glycemic control.

Abstract
PURPOSE Teneligliptin is a novel DPP-4 inhibitor in development for treating type 2 diabetes mellitus that does not require dose adjustment for diabetic patients with end-stage renal disease; however, it had not been known whether or not teneligliptin is safe or potent in dialysis patients. We conducted a prospective study to assess the utility of teneligliptin for diabetic patients undergoing hemodialysis. METHODS Blood glucose, glycated albumin, and HbA1c were measured every 4 weeks, at 4, 12, 20, and 28 weeks, and every 8 weeks, respectively, for patients treated with teneligliptin (n = 14; 7 patients newly started and 7 that switched from other medications) and patients of a control group who continued ongoing antidiabetic therapy (n = 29). RESULTS Blood glucose level showed a 36.7 mg/dl decrease from 4 weeks in the teneligliptin group (p < 0.05). The differences in glycated albumin (at 28 w) and HbA1c (at 24 w) between the teneligliptin group and the control group were -3.1 % (p < 0.05) and -0.57 % (p = 0.057), respectively. These parameters also decreased in patients who switched from voglibose 0.2 mg t.i.d. or vildagliptin 50 mg qd after teneligliptin administration. No case with hypoglycemia was identified. One patient had the dose of a laxative administered for constipation increased; however, no patient ceased teneligliptin due to side effects. CONCLUSION Teneligliptin 20 mg is well tolerated, safe, and significantly improves glycemic control in diabetic patients with end-stage renal disease. Teneligliptin 20 mg once daily was considered to be more potent than voglibose 0.2 mg t.i.d. or vildagliptin 50 mg qd.
