Efficacy and Safety of the Novel Dipeptidyl Peptidase-4 Inhibitor Gemigliptin in the Management of Type 2 Diabetes: A Meta-Analysis.
    Endocrinology and metabolism (Seoul, Korea), 2021, Volume: 36, Issue:2

    No meta-analysis has holistically analysed and summarised the efficacy and safety of gemigliptin in type 2 diabetes. The meta-analysis addresses this knowledge gap.. Electronic databases were searched for randomised controlled trials (RCTs) involving diabetes patients receiving gemigliptin in the intervention arm and placebo/active comparator in the control arm. The primary outcome was change in haemoglobin A1c (HbA1c). The secondary outcomes were alterations in glucose, glycaemic targets, lipids, insulin resistance, and adverse events.. Data from 10 RCTs involving 1,792 patients were analysed. Four had an active control group (ACG), with metformin/dapagliflozin/sitagliptin/glimepiride as the active comparator; six had a passive control group (PCG), with placebo/rosuvastatin as controls. HbA1c reduction by gemigliptin at 24 weeks was comparable to ACG (mean difference [MD], 0.09%; 95% confidence interval [CI], -0.06 to 0.23; P=0.24; I2=0%; moderate certainty of evidence [MCE]), but superior to PCG (MD, -0.91%; 95% CI, -1.18 to -0.63); P<0.01; I2=89%; high certainty of evidence [HCE]). Gemigliptin was superior to PCG regarding achieving HbA1c <7% (12 weeks: odds ratio [OR], 5.91; 95% CI, 1.34 to 26.08; P=0.02; I2=74%; 24 weeks: OR, 4.48; 95% CI, 2.09 to 9.60; P<0.01; I2=69%; HCE). Gemigliptin was comparable to ACG regarding achieving HbA1c <7% after 24 weeks (OR, 0.92; 95% CI, 0.52 to 1.63; P=0.77; I2=66%; MCE). Adverse events were similar between the gemigliptin and control groups (risk ratio [RR], 1.06; 95% CI, 0.82 to 1.36; P=0.66; I2=35%; HCE). The gemigliptin group did not have increased hypoglycaemia (RR, 1.19; 95% CI, 0.62 to 2.28; P=0.61; I2=19%; HCE).. Gemigliptin has good glycaemic efficacy and is well-tolerated over 6 months of use.

The pharmacokinetic considerations and adverse effects of DPP-4 inhibitors [corrected].
    Expert opinion on drug metabolism & toxicology, 2014, Volume: 10, Issue:6

    Dipeptidyl-peptidase-4 (DPP-4) inhibitors are a class of anti-hyperglycemic agents with proven efficacy in patients with type 2 diabetes mellitus (T2DM).. 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.. 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.

Pharmacokinetic and pharmacodynamic interaction of DWP16001, a sodium-glucose cotransporter 2 inhibitor, with gemigliptin and metformin in healthy adults.
    British journal of clinical pharmacology, 2023, Volume: 89, Issue:6

    DWP16001, a novel sodium-glucose cotransporter 2 inhibitor, is under clinical development for the treatment of type 2 diabetes mellitus. This study aimed to explore the pharmacokinetics (PK) and pharmacodynamics interaction of DWP16001 with gemigliptin and metformin.. A randomized, open-label, 2-sequence, 2-period crossover study was conducted in 34 healthy male subjects. All subjects received a single oral dose of DWP16001 2 mg with and without gemigliptin and metformin (8 days of 50 mg once-daily dose and 1000 mg twice daily dose for gemigliptin and metformin, respectively). Serial blood samples were collected for PK and serum glucose analysis, and timed urine samples were collected to analyse urine glucose excretion (UGE). The PK and pharmacodynamic parameters were analysed by the noncompartmental method.. The PK interactions of DWP16001, gemigliptin and metformin were not clinically significant. The geometric mean ratios (with 90% confidence intervals) of coadministration to separate administration for area under the time-concentration curves were 1.04 (1.02-1.06), 1.03 (0.98-1.09) and 1.17 (1.12-1.22), for gemigliptin, metformin and DWP16001 respectively. The UGE induced by DWP16001 was not affected by the coadministration of gemigliptin and metformin.. The results suggest that the DWP16001 could be added to metformin and gemigliptin combination therapy without dose adjustment.

Effects of Initial Combinations of Gemigliptin Plus Metformin Compared with Glimepiride Plus Metformin on Gut Microbiota and Glucose Regulation in Obese Patients with Type 2 Diabetes: The INTESTINE Study.
    Nutrients, 2023, Jan-03, Volume: 15, Issue:1

    The efficacy and safety of medications can be affected by alterations in gut microbiota in human beings. Among antidiabetic medications, incretin-based therapy such as dipeptidyl peptidase 4 inhibitors might affect gut microbiomes, which are related to glucose metabolism. This was a randomized, controlled, active-competitor study that aimed to compare the effects of combinations of gemigliptin−metformin vs. glimepiride−metformin as initial therapies on gut microbiota and glucose homeostasis in drug-naïve patients with type 2 diabetes. Seventy drug-naïve patients with type 2 diabetes (mean age, 52.2 years) with a glycated hemoglobin (HbA1c) level ≥7.5% were assigned to either gemigliptin−metformin or glimepiride−metformin combination therapies for 24 weeks. Changes in gut microbiota, biomarkers linked to glucose regulation, body composition, and amino acid blood levels were investigated. Although both treatments decreased the HbA1c levels significantly, the gemigliptin−metformin group achieved HbA1c ≤ 7.0% without hypoglycemia or weight gain more effectively than did the glimepiride−metformin group (59% vs. 24%; p < 0.05). At the phylum level, the Firmicutes/Bacteroidetes ratio tended to decrease after gemigliptin−metformin therapy (p = 0.065), with a notable depletion of taxa belonging to Firmicutes, including Lactobacillus, Ruminococcus torques, and Streptococcus (all p < 0.05). However, regardless of the treatment modality, a distinct difference in the overall gut microbiome composition was noted between patients who reached the HbA1c target goal and those who did not (p < 0.001). Treatment with gemigliptin−metformin resulted in a higher achievement of the glycemic target without hypoglycemia or weight gain, better than with glimepiride−metformin; these improvements might be related to beneficial changes in gut microbiota.

Efficacy and safety of enavogliflozin versus dapagliflozin added to metformin plus gemigliptin treatment in patients with type 2 diabetes: A double-blind, randomized, comparator-active study: ENHANCE-D study.
    Diabetes & metabolism, 2023, Volume: 49, Issue:4

    This study evaluated the efficacy and safety of enavogliflozin, a novel sodium-glucose cotransporter 2 inhibitor, versus dapagliflozin in Korean patients with type 2 diabetes mellitus (T2DM) inadequately controlled with metformin and gemigliptin.. In this multicenter, double-blind, randomized study, patients with inadequate response to metformin (≥ 1000 mg/day) plus gemigliptin (50 mg/day) were randomized to receive enavogliflozin 0.3 mg/day (n = 134) or dapagliflozin 10 mg/day (n = 136) in addition to the metformin plus gemigliptin therapy. The primary endpoint was change in HbA1c from baseline to week 24.. Both treatments significantly reduced HbA1c at week 24 (-0.92% in enavogliflozin group, -0.86% in dapagliflozin group). The enavogliflozin and dapagliflozin groups did not differ in terms of changes in HbA1c (between-group difference: -0.06%, 95% confidence interval [CI]: -0.19, 0.06) and fasting plasma glucose (between-group difference: -3.49 mg/dl [-8.08;1.10]). An increase in urine glucose-creatinine ratio was significantly greater in the enavogliflozin group than in the dapagliflozin group (60.2 g/g versus 43.5 g/g, P < 0.0001). The incidence of treatment-emergent adverse events was similar between the groups (21.64% versus 23.53%).. Enavogliflozin, added to metformin plus gemigliptin, was well tolerated and as effective as dapagliflozin in the treatment of patients with T2DM.

Comparison of the effects of gemigliptin versus glimepiride on cardiac function in patients with type 2 diabetes uncontrolled with metformin: The gemi-heart study.
    Diabetes, obesity & metabolism, 2023, Volume: 25, Issue:8

    To investigate the effects of gemigliptin on cardiac function and compare the effects of gemigliptin and glimepiride in patients with type 2 diabetes (T2D).. Sixty T2D patients being treated with metformin were assigned to a gemigliptin group (50 mg daily) or a glimepiride group (2 mg daily) for 24 weeks. The preadjudicated extension period was up to 52 weeks. Glucose metabolism variables and cardiac biomarkers were measured. Echocardiography was used to evaluate cardiac functions.. The HbA1c levels decreased significantly from 8.1% ± 0.6% to 6.8% ± 0.6% in the gemigliptin group and from 8.1% ± 0.6% to 7.0% ± 0.7% in the glimepiride group, without a between-group difference. Gemigliptin reduced insulin resistance, high sensitivity C-reactive protein and low-density lipoprotein cholesterol levels, and blood pressure, and increased adiponectin level compared with glimepiride therapy. Gemigliptin induced favourable changes in body composition. Left ventricular end-diastolic volume decreased in the gemigliptin group but increased in the glimepiride group, with a borderline between-group difference. Cardiac biomarkers did not change significantly in either group. At 52 weeks, the HbA1c levels in both groups increased slightly; 7.3% ± 0.8% in the gemigliptin group versus 7.7% ± 1.3% in the glimepiride group, without a between-group difference.. Gemigliptin had a comparable glucose-lowering efficacy without deleterious effects on cardiac functions or on biomarkers reflective of myocardial injury or heart failure during the 24-week observation period. However, larger, longer-term studies are needed to confirm these findings.

Efficacy of Gemigliptin Add-on to Dapagliflozin and Metformin in Type 2 Diabetes Patients: A Randomized, Double-Blind, Placebo-Controlled Study (SOLUTION).
    Endocrinology and metabolism (Seoul, Korea), 2023, Volume: 38, Issue:3

    This study evaluated the efficacy and safety of add-on gemigliptin in patients with type 2 diabetes mellitus (T2DM) who had inadequate glycemic control with metformin and dapagliflozin.. In this randomized, placebo-controlled, parallel-group, double-blind, phase III study, 315 patients were randomized to receive either gemigliptin 50 mg (n=159) or placebo (n=156) with metformin and dapagliflozin for 24 weeks. After the 24-week treatment, patients who received the placebo were switched to gemigliptin, and all patients were treated with gemigliptin for an additional 28 weeks.. The baseline characteristics were similar between the two groups, except for body mass index. At week 24, the least squares mean difference (standard error) in hemoglobin A1c (HbA1c) changes was -0.66% (0.07) with a 95% confidence interval of -0.80% to -0.52%, demonstrating superior HbA1c reduction in the gemigliptin group. After week 24, the HbA1c level significantly decreased in the placebo group as gemigliptin was administered, whereas the efficacy of HbA1c reduction was maintained up to week 52 in the gemigliptin group. The safety profiles were similar: the incidence rates of treatment-emergent adverse events up to week 24 were 27.67% and 29.22% in the gemigliptin and placebo groups, respectively. The safety profiles after week 24 were similar to those up to week 24 in both groups, and no new safety findings, including hypoglycemia, were noted.. Add-on gemigliptin was well tolerated, providing comparable safety profiles and superior efficacy in glycemic control over placebo for long-term use in patients with T2DM who had poor glycemic control with metformin and dapagliflozin.

Effect of Dipeptidyl Peptidase-4 (DPP-4) Inhibition on Biomarkers of Kidney Injury and Vascular Calcification in Diabetic Kidney Disease: A Randomized Controlled Trial.
    Journal of diabetes research, 2021, Volume: 2021

    Dipeptidyl peptidase-4 (DPP-4) inhibitors improve glycemic control and have pleiotropic effects on kidney injury, albuminuria, and vascular inflammation, especially in animal models. We evaluated the effects of a potent DPP4 inhibitor (gemigliptin) on these processes among patients with diabetic kidney disease (DKD).. This study employed a multicenter, prospective, randomized, placebo-controlled design. A total of 201 participants were enrolled and randomly assigned to one of two groups, one received treatment with 50 mg gemigliptin daily along with standard care for diabetes mellitus for 6 months. The changes in the coronary calcium score (CAC score), cardio-ankle vascular index (CAVI), estimated glomerular filtration rate (eGFR), vascular calcification level, and tubular renal injury marker expression were evaluated at baseline and 6 months.. In total, 182 patients completed the study. Significant reductions in hemoglobin A1C levels were observed in both groups. The changes in the CAC score, CAVI, eGFR, and level of proteinuria over the 6 months of the study did not significantly differ between the gemigliptin and control groups. However, biomarkers of vascular calcification, including serum bone alkaline phosphatase and kidney injury, including urine neutrophil gelatinase-associated lipocalin (NGAL)/Cr and urine liver fatty acid-binding protein (L-FABP)/Cr, were improved significantly in the gemigliptin treatment group compared with the control group. No serious adverse events were observed during the study.. Our study showed that gemigliptin significantly improved the expression of renal tubular injury biomarkers and vascular calcification levels among patients with DKD; however, gemigliptin did not affect renal function or coronary calcification compared with those observed in the control. A larger study with a longer follow-up is essential to verify these beneficial effects.

A Multicentre, Multinational, Open-Label, 52-Week Extension Study of Gemigliptin (LC15-0444) Monotherapy in Patients with Type 2 Diabetes Mellitus.
    Diabetes & metabolism journal, 2021, Volume: 45, Issue:4

    The purpose of this extension study was to assess the long-term efficacy and safety of gemigliptin 50 mg in patients with type 2 diabetes mellitus (T2DM). Patients with T2DM who had completed the initial 24-week study comparing gemigliptin monotherapy with placebo were eligible to enrol. In the open-label, 28-week extension study, all enrolled patients received gemigliptin, regardless of the treatment received during the initial 24-week study period. The mean reduction±standard deviation (SD) in glycosylated hemoglobin (HbA1c) observed after 24 weeks of treatment (-0.6%±1.1%) was further decreased for the gemi-gemi group and the mean change in HbA1c at week 52 from baseline was -0.9%±1.2% (P<0.0001). For the pbo-gemi group, HbA1c decreased after they were switched to gemigliptin, and the mean change in HbA1c at week 52 from baseline was -0.7%±1.2% (P<0.0001). Furthermore, the overall incidence of adverse events demonstrated that gemigliptin was safe and well tolerated up to 52 weeks.

Efficacy and safety of gemigliptin as add-on therapy to insulin, with or without metformin, in patients with type 2 diabetes mellitus (ZEUS II study).
    Diabetes, obesity & metabolism, 2020, Volume: 22, Issue:1

    The objective of this study was to evaluate the efficacy and safety of gemigliptin added to a stable dose of insulin alone or of insulin in combination with metformin in patients with type 2 diabetes mellitus. After a two-week run-in period, patients were randomized 2:1 to receive gemigliptin 50 mg or placebo once daily as add-on to background therapy with insulin or insulin plus metformin for 24 weeks. The primary endpoint was change in haemoglobin A1c (HbA1c) from baseline at Week 24. Baseline characteristics were similar between the gemigliptin (n = 188) and placebo (n = 95) groups in terms of HbA1c (8.1%). At Week 24, the gemigliptin group showed a statistically significant reduction in mean HbA1c from baseline as compared with placebo (between-group mean difference, -0.7% [95% CI, -0.9% to -0.4%]; P-value < 0.0001). The incidence of overall adverse events and the number of hypoglycaemic adverse events were similar between the study groups. Gemigliptin added to insulin alone or to insulin in combination with metformin resulted in superior glycaemic control compared to that in the placebo group and was well tolerated for 24 weeks in patients with type 2 diabetes mellitus, without causing weight gain or increasing the incidence of hypoglycaemia.

Comparison of the effects of gemigliptin and dapagliflozin on glycaemic variability in type 2 diabetes: A randomized, open-label, active-controlled, 12-week study (STABLE II study).
    Diabetes, obesity & metabolism, 2020, Volume: 22, Issue:2

    The aim of this study was to compare the effect of gemigliptin, a dipeptidyl peptidase-4 inhibitor, and dapagliflozin, a sodium glucose co-transporter-2 inhibitor, on glycaemic variability in type 2 diabetes patients.. In this randomized, blinded end point, multicentre clinical trial, we enrolled 71 patients with type 2 diabetes who were inadequately controlled with metformin alone or were drug naïve. The participants were randomized to receive gemigliptin 50 mg (n = 35) or dapagliflozin 10 mg (n = 36) daily for 12 weeks. Glycaemic variability was estimated by mean amplitude of glycaemic excursions (MAGE), standard deviation (SD) and coefficient of variation (CV) using a 6-day continuous glucose monitoring system. The primary efficacy endpoint was change in MAGE after 12 weeks compared to baseline.. Intergroup differences in baseline characteristics were not significant. The adjusted mean change (± standard error) in MAGE after 12 weeks in the gemigliptin and dapagliflozin groups was -27.2 ± 4.4 mg/dL and -7.9 ± 4.9 mg/dL, respectively. Between-group comparisons showed a significantly larger reduction in MAGE in the gemigliptin group (-19.2 mg/dL; 95% CI, -31.3 to -7.2; P = .002). Measures of SD and CV also showed a significantly larger reduction in the gemigliptin group. Average glycaemic control, estimated by HbA1c, fasting glucose and safety profiles, was comparable between the two groups.. Compared to dapagliflozin, gemigliptin significantly improved glycaemic variability, with similar glucose-lowering efficacy and safety profiles in patients with type 2 diabetes who were inadequately controlled with metformin alone or were drug naïve.

A prospective cohort study on effects of gemigliptin on cardiovascular outcomes in patients with type 2 diabetes (OPTIMUS study).
    Scientific reports, 2020, 11-04, Volume: 10, Issue:1

    This study was performed to evaluate the long-term cardiovascular safety of gemigliptin in patients with type 2 diabetes mellitus (T2DM). After screening, eligible patients with T2DM were enrolled, received gemigliptin, and were followed up for a median of 2.50 years. The primary outcome was a composite of confirmed cardiovascular death, nonfatal myocardial infarction, or nonfatal ischemic stroke (3-point major adverse cardiovascular event [MACE]). The key secondary outcomes were incidence of all-cause mortality and any other cardiovascular events. A total of 5179 patients were included in the study and 5113 were treated with gemigliptin. Overall, the primary outcome occurred in 26 patients within 12 months (estimated incidence by Cox proportional hazard model 0.49%, 95% CI 0.29-0.69%) and in 54 patients within 54 months (estimated incidence from Cox proportional hazard model 1.35%, 95% CI 0.92-1.77%). During the study period, the incidence rates of each component of the primary composite outcome were 0.04% (0.2 events per 1000 person-years) for cardiovascular death, 0.51% (2.2 events per 1000 person-years) for nonfatal myocardial infarction, and 0.61% (2.5 events per 1000 person-years) for nonfatal ischemic stroke. The incidence of all-cause mortality was 0.82% (3.2 events per 1000 person-years) and the incidences of other cardiovascular events were all less than 0.3%. In conclusion, T2DM patients who received gemigliptin exhibited a low incidence of the primary composite MACE and all-cause mortality. Therefore, the use of gemigliptin is expected to be safe without an increase in cardiovascular risk.Trial registration: The study was registered at ClinicalTrials.gov (identifier: NCT02290301).

Efficacy and safety of fixed-dose combination therapy with gemigliptin (50 mg) and rosuvastatin compared with monotherapy in patients with type 2 diabetes and dyslipidaemia (BALANCE): A multicentre, randomized, double-blind, controlled, phase 3 trial.
    Diabetes, obesity & metabolism, 2019, Volume: 21, Issue:1

    To evaluate the efficacy and safety of a fixed-dose combination (FDC) of gemigliptin and rosuvastatin in patients with type 2 diabetes and dyslipidaemia.. A total of 33 hospitals in Korea participated in this randomized, double-blind trial of diabetic patients with dyslipidaemia. A total of 290 participants were randomly assigned at a 1:1:1 ratio to receive an FDC of gemigliptin (50 mg) and rosuvastatin (20 mg) (GEMI/ROSU FDC group), gemigliptin (50 mg) (GEMI group) or rosuvastatin (20 mg) (ROSU group). Rosuvastatin was up-titrated from 5 to 20 mg/d throughout the study period. Primary efficacy measures were changes in HbA1c and LDL-C from baseline to Week 24 between the GEMI/ROSU FDC and ROSU groups and between the GEMI/ROSU FDC and GEMI groups, respectively. Secondary efficacy measures were changes in HbA1c and LDL-C between the GEMI/ROSU FDC and GEMI groups and between the GEMI/ROSU FDC and ROSU groups, respectively.. After 24 weeks of treatment, a significant reduction in HbA1c from baseline was noted in the GEMI/ROSU FDC group (-0.81% of LS mean; P < 0.0001 vs ROSU group), in addition to a significant reduction in LDL-C concentration (-51.9% of LS mean percentage changes, P < 0.0001 vs GEMI group). HbA1c was significantly reduced from baseline in both the GEMI/ROSU FDC and GEMI groups, but the reduction in HbA1c was significantly greater in the GEMI group than in the GEMI/ROSU FDC group, despite receiving the same dose of gemigliptin. The decrease in LDL-C over time was similar between the GEMI/ROSU FDC and ROSU groups. There were no significant differences in adverse events among the groups.. The FDC of gemigliptin and rosuvastatin is safe and is effective in reducing both blood glucose and LDL-C levels; thus, it could be a good therapeutic choice for type 2 diabetic patients with dyslipidaemia.

Comparative efficacy and safety of gemigliptin versus linagliptin in type 2 diabetes patients with renal impairment: A 40-week extension of the GUARD randomized study.
    Diabetes, obesity & metabolism, 2018, Volume: 20, Issue:2

    The long-term safety and efficacy of gemigliptin was evaluated in the present extension study after a 12-week study during a 40-week follow-up period.. The main study was a randomized, placebo-controlled, double-blinded, phase IIIb study in which 50 mg of gemigliptin (N = 66) or placebo (N = 66) was administered to patients with type 2 diabetes mellitus (T2DM) and moderate or severe renal impairment over a 12-week period. Patients with a glycated haemoglobin (HbA1c) level of 7% to 11% and an estimated glomerular filtration rate (eGFR) of 15 to 59 mL/min/1.73 m. The HbA1c levels of both groups were significantly reduced at week 52 compared with baseline. Specifically, the adjusted mean change ± standard error in HbA1c level in the gemigliptin and placebo/linagliptin groups was 1.00% ± 0.21% and 0.65% ± 0.22% lower at week 52 than at baseline (P < .001 and P = .003), respectively. No significant difference in the change in HbA1c level was found between the 2 groups (P = .148). Trends in fasting plasma glucose, fructosamine and glycated albumin levels in the 2 groups were similar to trends in HbA1c levels. The eGFR of both groups was also significantly lower at week 52 than at baseline, and no significant difference in change in eGFR was found between the 2 groups. In contrast, both drugs had little effect on urinary albumin excretion, although both drugs significantly reduced the urinary type IV collagen level. The overall rates of adverse events were similar between the 2 groups.. Gemigliptin and linagliptin did not differ with respect to safety and efficacy in patients with T2DM and renal impairment. The 2 drugs had similar glucose-lowering effects, and the changes in eGFR and albuminuria were also similar. Additionally, the risk of side effects, including hypoglycaemia, was similar between the 2 groups.

A 52-week extension study of switching from gemigliptin vs sitagliptin to gemigliptin only as add-on therapy for patients with type 2 diabetes who are inadequately controlled with metformin alone.
    Diabetes, obesity & metabolism, 2018, Volume: 20, Issue:6

    We investigated the long-term efficacy and safety of gemigliptin and the efficacy and safety of gemigliptin treatment after once-daily treatment with sitagliptin 100 mg, in patients with type 2 diabetes. This was a 28-week extension of a 24-week, randomized, double-blind, parallel study of gemigliptin or sitagliptin added to ongoing metformin therapy. After randomization to sitagliptin 100 mg qd (S), gemigliptin 25 mg bid (G1) or gemigliptin 50 mg qd (G2) and after completing 24 weeks of treatment, 118 patients switched from gemigliptin 25 mg bid to 50 mg qd (G1/G2), 111 patients continued gemigliptin 50 mg qd (G2/G2) and 106 patients switched from sitagliptin 100 mg qd to gemigliptin 50 mg qd (S/G2). All 3 treatments reduced glycated haemoglobin (HbA1c) (S/G2,-0.99% [95% CI -1.25%, -0.73%]; G1/G2, -1.11% [95% CI -1.33%, -0.89%]; G2/G2, -1.06% [95% CI -1.28%, -0.85%]). The percentage of patients achieving HbA1c < 6.5% was 27.6% in the G1/G2 group at both Week 24 and Week 52, and ranged from 27.3% to 32.7% in the G2/G2 group (difference in proportions, 5% [95% CI -6%, 17%]), while it increased from 6.8% to 27.3% from Week 24 to Week 52 in the S/G2 group (difference in proportions, 20% [95% CI 7%, 34%]). Addition of gemigliptin 50 mg qd to metformin was shown to be efficacious for 52 weeks. Switching from sitagliptin 100 mg to gemigliptin 50 mg showed consistent glyacemic control over the previous treatment.

Pharmacokinetic Equivalence of the High Dose Strength Fixed-Dose Combination Tablet of Gemigliptin/Metformin Sustained Release (SR) and Individual Component Gemigliptin and Metformin XR Tablets in Healthy Subjects.
    Journal of Korean medical science, 2018, Oct-08, Volume: 33, Issue:41

    In type 2 diabetes mellitus therapy, fixed-dose combination (FDC) can offer not only benefits in glucose control via the combined use of agents, but also increase patient compliance. The aim of this study was to assess the pharmacokinetic equivalence of the high dose of the FDC tablet (gemigliptin/metformin sustained release [SR] 50/1,000 mg) and a corresponding co-administered dose of individual tablets.. This study was randomized, open-label, single dose, two treatments, two-period, crossover study, which included 24 healthy subjects. Subjects received the FDC or individual tablets of gemigliptin (50 mg) and metformin XR (1,000 mg) in each period. Geometric mean ratios (GMRs) and 90% confidence intervals (CIs) of maximum plasma concentration (C. The GMRs (FDC tablets/co-administration; 90% CIs) for C. FDC tablet exhibited pharmacokinetic equivalence and comparable safety and tolerability to co-administration of corresponding doses of gemigliptin and metformin XR as individual tablets.

Efficacy and safety of initial combination therapy with gemigliptin and metformin compared with monotherapy with either drug in patients with type 2 diabetes: A double-blind randomized controlled trial (INICOM study).
    Diabetes, obesity & metabolism, 2017, Volume: 19, Issue:1

    Gemigliptin is a new dipeptidyl peptidase-IV inhibitor. We investigated the efficacy and safety of initial combination therapy with gemigliptin and metformin compared with monotherapy with either drug in patients with type 2 diabetes (T2D).. A total of 433 T2D patients with a glycosylated haemoglobin (HbA1c) level of 7.5% to 11.0% and a fasting plasma glucose (FPG) concentration <270 mg/dL were randomly assigned to 3 groups: (1) gemigliptin 50 mg qd + metformin 1000 to 2000 mg qd (titrated individually), (2) gemigliptin 50 mg qd, or (3) metformin 1000 to 2000 mg qd. The primary end-point was the change in HbA1c level after 24 weeks. Secondary end-points were the changes in FPG, insulin, proinsulin and C-peptide levels. The percentages of responders who achieved an HbA1c level <7% (or <6.5%) were compared between treatment groups.. Baseline HbA1c levels were 8.7% in all groups. The mean changes in HbA1c level from baseline to week 24 were -2.06%, -1.24% and -1.47% in the combination, gemigliptin monotherapy and metformin monotherapy groups, respectively. The 95% confidence intervals for between-group differences in HbA1c changes were -1.02 to -0.63 in the combination group vs the gemigliptin group and -0.82 to -0.41 vs the metformin group, which confirmed the superiority of combination therapy. A significantly higher percentage of patients in the combination therapy group reached the target HbA1c level <7% (or <6.5%) compared with the monotherapy groups. No severe side effects were observed.. In T2D patients, the initial combination of gemigliptin and metformin had superior efficacy without safety concerns compared with monotherapy with either drug.

Effects of gemigliptin, a dipeptidyl peptidase-4 inhibitor, on lipid metabolism and endotoxemia after a high-fat meal in patients with type 2 diabetes.
    Diabetes, obesity & metabolism, 2017, Volume: 19, Issue:3

    We aimed to investigate the effects of gemigliptin, a dipeptidyl peptidase-4 inhibitor, on postprandial lipoprotein levels and endotoxemia in a randomized, double-blind, placebo-controlled, crossover study. Ten people with type 2 diabetes mellitus (T2DM), inadequately controlled with oral antidiabetic medications and/or lifestyle modification, were randomized to gemigliptin or placebo for 4 weeks. At the end of each treatment phase, the study participants underwent a high-fat meal tolerance test and needle aspiration of abdominal subcutaneous adipose tissue. The median (range) fasting and total area under the curve of apolipoprotein B48 (ApoB48) were significantly lower with gemigliptin than with placebo (2.9 [1.5-15.8] µg/mL vs 4.2 [1.3-23.4] µg/mL; P = .020; 35.3 [14.4-87.4] µg/mL × hour vs 42.2 [17.5-109.0] µg/mL × hour; P = .020, respectively), whereas apolipoprotein B100 showed no significant difference. Serum endotoxin levels were undetectable in 70% of the samples, so we were not able to evaluate the effect of gemigliptin on endotoxemia. The gene expression of inflammatory cytokines in subcutaneous adipose tissue was not affected by gemigliptin. Gemigliptin reduced ApoB48 levels after a high-fat meal in participants with T2DM. Whether systemic endotoxin levels can be reduced by gemigliptin requires further investigation.

Efficacy, safety and albuminuria-reducing effect of gemigliptin in Korean type 2 diabetes patients with moderate to severe renal impairment: A 12-week, double-blind randomized study (the GUARD Study).
    Diabetes, obesity & metabolism, 2017, Volume: 19, Issue:4

    This multicentre, randomized, double-blind study investigated the efficacy and safety of gemigliptin in Korean type 2 diabetes mellitus (T2DM) patients with moderate to severe renal impairment (RI).. The study comprised a 12-week main part and a 40-week extension. We report here the results from the main part. In total, 132 patients were randomized to receive gemigliptin (n = 66) or placebo (n = 66). Changes in glycated haemoglobin (HbA1c; primary endpoint), other glycaemic control parameters (fasting plasma glucose, glycated albumin and fructosamine), lipid profiles, renal function parameters and safety profiles were evaluated.. A 12-week treatment with gemigliptin improved glycaemic control and provided UACR reduction in T2DM patients with moderate to severe RI. Gemigliptin was well tolerated, with no additional risk of hypoglycaemia and change in body weight.

Efficacy and safety of gemigliptin, a dipeptidyl peptidase-4 inhibitor, in patients with type 2 diabetes mellitus inadequately controlled with combination treatment of metformin and sulphonylurea: a 24-week, multicentre, randomized, double-blind, placebo-
    Diabetes, obesity & metabolism, 2017, Volume: 19, Issue:5

    To assess the efficacy and safety of gemigliptin, a dipeptidyl peptidase-4 inhibitor, added to metformin and sulphonylurea in patients with type 2 diabetes (T2DM).. We conducted a randomized, double-blind, placebo-controlled trial in 219 Korean patients inadequately controlled with metformin and glimepiride. Participants were randomized to gemigliptin 50 mg once daily or placebo added to metformin and glimepiride. The primary endpoint was change in glycated haemoglobin (HbA1c) level from baseline to week 24.. The baseline HbA1c was 8.2% in both groups. The addition of gemigliptin to metformin and glimepiride significantly reduced HbA1c levels at week 24 compared with placebo (between-group difference in adjusted mean change -0.87%, 95% confidence interval [CI] -1.09% to -0.64%). Fasting plasma glucose level was also significantly reduced with gemigliptin (-0.93 mmol/L, 95% CI -1.50 to -0.35 mmol/L), and a higher proportion of participants achieved an HbA1c level of <7% (39.3% vs 5.5%; P <.001) in the gemigliptin group than in the placebo group. Total cholesterol and LDL cholesterol were modestly but significantly reduced in the gemigliptin group compared with the placebo group (-0.21 mmol/L, 95% CI -0.38 to -0.03 mmol/L for total cholesterol, -0.18 mmol/L, 95% CI -0.34 to -0.01 mmol/L for LDL cholesterol). The incidence of hypoglycaemia was 9.4% in the gemigliptin group and 2.7% in the placebo group.. Gemigliptin significantly improved glycaemic control in patients with T2DM inadequately controlled with metformin and sulphonylurea. The incidence of hypoglycaemia was higher with gemigliptin than with placebo, which highlights the importance of optimal dose adjustment for sulphonylurea.

Effect of gemigliptin on glycaemic variability in patients with type 2 diabetes (STABLE study).
    Diabetes, obesity & metabolism, 2017, Volume: 19, Issue:6

    The aim of this study was to evaluate the effect of gemigliptin vs sitagliptin or glimepiride as initial combination therapy with metformin on glycaemic variability and to assess the correlation between glycaemic variability reduction and the dipeptidyl peptidase-4 (DPP-4) inhibition in patients with type 2 diabetes. This multicentre, randomized, active-controlled, open-label exploratory study included 69 patients with HbA1c > 7.5%. Subjects were randomized to receive gemigliptin 50 mg (n = 24), sitagliptin 100 mg (n = 23) or glimepiride 2 mg (n = 22) for 12 weeks. After 12 weeks, the change in mean amplitude of glycaemic excursion (MAGE) compared with baseline was significantly lower in the DPP-4 inhibitor groups compared with that in patients who received glimepiride. Furthermore, the standard deviation (SD) of glucose was significantly lower in patients who received gemigliptin than that in patients who received sitagliptin or glimepiride. The DPP-4 inhibition was significantly correlated with changes in MAGE and SD of glucose. In conclusion, gemigliptin and sitagliptin were more effective than glimepiride in reducing glycaemic variability as initial combination therapy with metformin in patients with type 2 diabetes, and the DPP-4 inhibition was associated with a reduction in glycaemic variability.

Evaluation of the pharmacokinetics of the DPP-4 inhibitor gemigliptin when coadministered with rosuvastatin or irbesartan to healthy subjects.
    Current medical research and opinion, 2015, Volume: 31, Issue:2

    Gemigliptin is a selective DPP4 inhibitor used to treat type 2 diabetes. The objective of this study was to evaluate the pharmacokinetics (PKs) of gemigliptin, rosuvastatin, and irbesartan monotherapies and combination therapies.. Randomized, open-label, three-treatment, six-sequence, three-period, crossover studies were performed on healthy male volunteers. The three treatments were: 50 mg gemigliptin alone; 20 mg rosuvastatin (part A) or 300 mg irbesartan alone (part B); and rosuvastatin or irbesartan with concomitant gemigliptin. Each drug was administered as part of once daily, 7 day, repeated dosing regimens with a 14 day washout period.. NCT01823133 (part A) and NCT01825850 (part B).. The primary PK parameters - Cmax and AUCτ - were compared to the geometric mean ratios (GMRs) and 90% confidence intervals (90% CIs) that were determined for the combination therapies and monotherapies.. A total of 60 participants were administered the study drugs, and 52 participants (27 participants in part A; 25 participants in part B) were analyzed as part of the PK dataset. In part A, the GMRs (gemigliptin + rosuvastatin/gemigliptin) of the Cmax and AUCτ values of gemigliptin were 0.955 (90% CI = 0.874-1.044) and 1.023 (90% CI = 0.991-1.057), and those of rosuvastatin were 1.012 (90% CI = 0.946-1.084) and 1.086 (90% CI = 1.032-1.142), respectively. In part B, the GMRs of the Cmax and AUCτ values of gemigliptin were 1.046 (90% CI = 0.964-1.134) and 1.035 (90% CI = 1.005-1.065), and those of irbesartan were 0.966 (90% CI = 0.897-1.040) and 1.050 (90% CI = 0.993-1.111), respectively. The limitations of this study include its relatively short treatment period and small sample size, as only healthy participants were included.. Gemigliptin does not affect the PK properties of rosuvastatin or irbesartan; also, rosuvastatin and irbesartan do not affect the PKs of gemigliptin.

A multicentre, multinational, randomized, placebo-controlled, double-blind, phase 3 trial to evaluate the efficacy and safety of gemigliptin (LC15-0444) in patients with type 2 diabetes.
    Diabetes, obesity & metabolism, 2013, Volume: 15, Issue:5

    This study was designed to assess the efficacy and safety of the dipeptidyl peptidase IV inhibitor gemigliptin (LC15-0444) 50 mg versus placebo in patients with type 2 diabetes.. We conducted a 24-week, randomized, double-blind, placebo-controlled phase III trial in 182 patients (74 from Korea and 108 from India) with type 2 diabetes. After an initial 2 weeks of a diet and exercise programme followed by 2 weeks of a single-blind placebo run-in period, eligible patients were randomized to gemigliptin 50 mg or placebo, receiving the assigned treatment for 24 weeks. HbA1c and fasting plasma glucose (FPG) were measured periodically, and oral glucose tolerance test was performed at baseline and weeks 12 and 24.. At week 24, gemigliptin treatment led to significant reductions in HbA1c measurements compared to placebo (adjust mean after subtracting the placebo effect size: -0.71%, 95% confidence interval: -1.04 to -0.37%). A significantly greater proportion of patients achieved an HbA1c <7% with gemigliptin than with placebo. The placebo-subtracted FPG change from baseline at week 24 was -19.80 mg/dl. The overall incidence rates for adverse events were similar in the gemigliptin and placebo groups.. This study showed the efficacy and safety of gemigliptin 50 mg administered once daily as a monotherapy for type 2 diabetes patients.

Efficacy and safety of the dipeptidyl peptidase-4 inhibitor gemigliptin compared with sitagliptin added to ongoing metformin therapy in patients with type 2 diabetes inadequately controlled with metformin alone.
    Diabetes, obesity & metabolism, 2013, Volume: 15, Issue:6

    This study was designed to assess the efficacy and safety of a dipeptidyl peptidase-4 inhibitor, gemigliptin versus sitagliptin added to metformin in patients with type 2 diabetes.. We conducted a double-blind, randomized, active-controlled trial in 425 Asian patients with inadequately controlled type 2 diabetes being treated with metformin alone. Eligible patients were randomized into three groups: 50 mg gemigliptin qd, 25 mg gemigliptin bid or sitagliptin 100 mg qd added to ongoing metformin treatment for 24 weeks. Haemoglobin A1c (HbA1c) and fasting plasma glucose (FPG) were measured periodically, and oral glucose tolerance tests were performed at baseline and 24 weeks after starting the treatment regimen.. Twenty-four weeks later, adding gemigliptin (50 mg/day) to ongoing metformin therapy significantly improved glycaemic control. Reduction in HbA1c caused by 50 mg gemigliptin qd (-0.77% ± 0.8) was non-inferior to that caused by 100 mg sitagliptin qd (-0.8% ± 0.85). Proportion of patients achieving HbA1c <7% while taking 25 mg gemigliptin bid (50%) or 50 mg gemigliptin qd (54.07%) was comparable to the results with 100 mg sitagliptin qd (48.87%). There were significant decreases in FPG, postprandial glucose and AUC0-2 h glucose, as well as increases in GLP-1 and β cell sensitivity to glucose (supported by homeostasis model assessment of β-cell function, postprandial 2-h c-peptide and insulinogenic index) in patients receiving gemigliptin treatment with their metformin therapy. There was no increased risk of adverse effects with this dose of gemigliptin compared with sitagliptin 100 mg qd.. Addition of gemigliptin 50 mg daily to metformin was shown to be efficacious, well tolerated and non-inferior to sitagliptin in patients with type 2 diabetes mellitus.

A multicenter, randomized, placebo-controlled, double-blind phase II trial evaluating the optimal dose, efficacy and safety of LC 15-0444 in patients with type 2 diabetes.
    Diabetes, obesity & metabolism, 2010, Volume: 12, Issue:12

    The objective of this study was to evaluate the optimal dose, efficacy and safety of a novel dipeptidyl peptidase-4 (DPP-IV) inhibitor, LC15-0444, in Korean subjects with type 2 diabetes mellitus treated by diet and exercise.. This study was a double-blind, randomized, multicenter and parallel-group, dose-range finding study. We enrolled 145 patients (91 men and 54 women) with a median age of 53 years and a median body mass index of 25.1 kg/m(2) . The median baseline fasting plasma glucose (FPG) was 8.1 mmol/l, the median HbA1c was 7.9% and the median time since the diagnosis of diabetes was 3 years. After 2 weeks of an exercise/diet programme followed by 2 weeks of a placebo period, the subjects were randomized to one of the four following groups for a 12-week active treatment period: placebo and 50, 100 or 200 mg of LC15-0444.. All three doses of LC15-0444 significantly reduced the HbA1c from baseline compared to the placebo group (-0.06 vs. -0.98, -0.74 and -0.78% in the placebo and 50, 100 and 200 mg groups, respectively), without a significant difference between the doses. Subjects with a higher baseline HbA1c (≥8.5%) had a greater reduction in HbA1c. Insulin secretory function, as assessed using homeostasis model assessment-beta cell, C-peptide and the insulinogenic index, improved significantly with LC15-0444 treatment. Insulin sensitivity, as assessed using homeostasis model assessment-insulin resistance, also improved significantly after 12 weeks of treatment. The 50 and 200 mg groups had significantly reduced total cholesterol and low-density lipoprotein cholesterol levels at 12 weeks compared to the placebo group. No dosage of LC15-0444 affected weight or waist circumference. The incidences of adverse events were similar in all study subjects.. LC15-0444 monotherapy (50 mg for 12 weeks) improved the HbA1c, FPG level, oral glucose tolerance test results, β-cell function and insulin sensitivity measures, and was well tolerated in Korean subjects with type 2 diabetes.

Gemigliptin, a DPP4 inhibitor, ameliorates nonalcoholic steatohepatitis through AMP-activated protein kinase-independent and ULK1-mediated autophagy.
    Molecular metabolism, 2023, Volume: 78

    Abnormal autophagic function and activated inflammasomes are typical features in the liver of patients with non-alcoholic steatohepatitis (NASH). Here, we explored whether gemigliptin, a dipeptidyl peptidase 4 (DPP4) inhibitor for treatment of type 2 diabetes, can induce autophagy and regulate inflammasome activation as a potential NASH treatment independent of its anti-diabetic effect.. Expression analysis was performed using human liver samples obtained from 18 subjects who underwent hepatectomy. We explored the function and mechanism of gemigliptin using a methionine- and choline-deficient diet (MCD)-induced NASH mouse model and HepG2 cells cultured in MCD-mimicking medium.. Autophagy was suppressed by marked decreases in the expression of ULK1 and LC3II/LC3I ratio in human NAFLD/NASH patients, a NASH mouse model, and HepG2 cells cultured with MCD-mimicking media. Surprisingly, we found that the expression of p-AMPK decreased in liver tissues from patients with steatosis but was restored in NASH patients. The expression of p-AMPK in the NASH mouse model was similar to that of the control group. Hence, these results indicate that autophagy was reduced in NASH via an AMPK-independent pathway. However, gemigliptin treatment attenuated lipid accumulation, inflammation, and fibrosis in the liver of MCD diet-fed mice with restoration of ULK1 expression and autophagy induction. In vitro, gemigliptin alleviated inflammasome activation through induction of ULK1-dependent autophagy. Furthermore, gemigliptin treatment upregulated ULK1 expression and activated AMPK even after siRNA-mediated knockdown of AMPKα1/2 and ULK1, respectively.. Collectively, these results suggest that gemigliptin ameliorated NASH via AMPK-independent, ULK1-mediated effects on autophagy.

Gemigliptin exerts protective effects against doxorubicin-induced hepatotoxicity by inhibiting apoptosis via the regulation of fibroblast growth factor 21 expression.
    Biochemical and biophysical research communications, 2022, 10-20, Volume: 626

    Doxorubicin is a highly effective anticancer agent that causes hepatotoxicity and cardiotoxicity in patients. Fibroblast growth factor 21, a well-known regulator of glucose and lipid metabolism, exerts cardioprotective effects. Gemigliptin and dipeptidyl peptidase-4 inhibitors are widely used in the treatment of patients with type 2 diabetes. The protective effects of gemigliptin on hepatotoxicity via the increase in fibroblast growth factor 21 expression has not yet been elucidated. This study was designed to investigate the protective effects of gemigliptin against doxorubicin-induced hepatotoxicity via the upregulation of fibroblast growth factor 21 expression in the cultured murine hepatocyte cell line, AML12.. Murine hepatocyte AML12 cells were treated with doxorubicin, fibroblast growth factor 21 and gemigliptin in 0.5% fetal bovine serum medium for 24 h at the indicated doses. Cells were transfected with the fibroblast growth factor 21 small interfering RNA for 24 h, followed by protein isolation.. Fibroblast growth factor 21 expression levels were increased during doxorubicin-induced hepatotoxicity in the murine hepatocyte AML12 cells. Fibroblast growth factor 21 treatment prevented doxorubicin-induced hepatotoxicity by attenuating apoptosis. Gemigliptin prevented doxorubicin-induced hepatotoxicity by upregulating fibroblast growth factor 21 expression. However, the protective effects of gemigliptin were blocked by fibroblast growth factor 21 inhibition in doxorubicin-treated AML12 cells.. These results indicate that gemigliptin exhibits protective effects against doxorubicin-induced hepatotoxicity by upregulating the fibroblast growth factor 21 expression levels in the cultured murine hepatocyte AML12 cells.

    Transplantation proceedings, 2019, Volume: 51, Issue:10

    Gemigliptin is a potent, selective dipeptidyl peptidase (DPP)-4 inhibitor that does not require any dosage adjustment based on renal function. It is also known to have no apparent interaction with commonly used drugs. In the present study, we aimed to evaluate the glucose-lowering efficacy and safety of gemigliptin in post-transplant patients with type 2 diabetes mellitus (T2D).. A total of 84 patients who were prescribed gemigliptin for more than 180 days after transplantation were analyzed retrospectively. Six-month changes in blood glucose and glycated hemoglobin (HbA1c) levels were checked to assess glycemic efficacy. Safety was evaluated by examining its influence on immunosuppressive treatment, as determined by the blood trough level and dosage of calcineurin inhibitors, as well as changes in parameters related to liver and renal function.. Six months of gemigliptin treatment significantly lowered blood glucose level (HbA1c: 8.16 ± 1.69 to 7.44 ± 1.26%; P < .001). There were no significant changes in blood trough levels of immunosuppressants, including tacrolimus, cyclosporine, and sirolimus. The dosage of immunosuppressants was also stable. In addition, there were no significant changes in the levels of liver enzymes and renal function during 6 months of treatment.. Gemigliptin robustly lowered blood glucose levels without exerting any significant effect on immunosuppressive treatment, renal function, and liver enzymes in post-transplant patients with T2D.

A comparison of effects of DPP-4 inhibitor and SGLT2 inhibitor on lipid profile in patients with type 2 diabetes.
    Lipids in health and disease, 2017, Apr-13, Volume: 16, Issue:1

    Previous studies suggest that dipeptidyl peptidase-4 (DPP-4) inhibitors and sodium glucose cotransporter 2 (SGLT2) inhibitors have different effects on the lipid profile in patients with type 2 diabetes. We investigated the effects of DPP-4 inhibitors and SGLT2 inhibitors on the lipid profile in patients with type 2 diabetes.. From January 2013 to December 2015, a total of 228 patients with type 2 diabetes who were receiving a DPP-4 inhibitor or SGLT2 inhibitor as add-on therapy to metformin and/or a sulfonylurea were consecutively enrolled. We compared the effects of DPP-4 inhibitors and SGLT2 inhibitors on the lipid profile at baseline and after 24 weeks of treatment. To compare lipid parameters between the two groups, we used the analysis of covariance (ANCOVA).. A total of 184 patients completed follow-up (mean age: 53.1 ± 6.9 years, mean duration of diabetes: 7.1 ± 5.7 years). From baseline to 24 weeks, HDL-cholesterol (HDL-C) levels were increased by 0.5 (95% CI, -0.9 to 2.0) mg/dl with a DPP-4 inhibitor and by 5.1 (95% CI, 3.0 to 7.1) mg/dl with an SGLT2 inhibitor (p = 0.001). LDL-cholesterol (LDL-C) levels were reduced by 8.4 (95% CI, -14.0 to -2.8) mg/dl with a DPP-4 inhibitor, but increased by 1.3 (95% CI, -5.1 to 7.6) mg/dl with an SGLT2 inhibitor (p = 0.046). There was no significant difference in the mean hemoglobin A1c (8.3 ± 1.1 vs. 8.0 ± 0.9%, p = 0.110) and in the change of total cholesterol (TC) (p = 0.836), triglyceride (TG) (p = 0.867), apolipoprotein A (p = 0.726), apolipoprotein B (p = 0.660), and lipoprotein (a) (p = 0.991) between the DPP-4 inhibitor and the SGLT2 inhibitor.. The SGLT2 inhibitor was associated with a significant increase in HDL-C and LDL-C after 24 weeks of SGLT2 inhibitor treatment in patients with type 2 diabetes compared with those with DPP-4 inhibitor treatment in this study.. This study was conducted by retrospective medical record review.

The Dose-Dependent Organ-Specific Effects of a Dipeptidyl Peptidase-4 Inhibitor on Cardiovascular Complications in a Model of Type 2 Diabetes.
    PloS one, 2016, Volume: 11, Issue:3

    Although dipeptidyl peptidase-4 (DPP-4) inhibitors have been suggested to have a non-glucoregulatory protective effect in various tissues, the effects of long-term inhibition of DPP-4 on the micro- and macro-vascular complications of type 2 diabetes remain uncertain. The aim of the present study was to investigate the organ-specific protective effects of DPP-4 inhibitor in rodent model of type 2 diabetes.. Eight-week-old diabetic and obese db/db mice and controls (db/m mice) received vehicle or one of two doses of gemigliptin (0.04 and 0.4%) daily for 12 weeks. Urine albumin excretion and echocardiography measured at 20 weeks of age. Heart and kidney tissue were subjected to molecular analysis and immunohistochemical evaluation.. Gemigliptin effectively suppressed plasma DPP-4 activation in db/db mice in a dose-dependent manner. The HbA1c level was normalized in the 0.4% gemigliptin, but not in the 0.04% gemigliptin group. Gemigliptin showed a dose-dependent protective effect on podocytes, anti-apoptotic and anti-oxidant effects in the diabetic kidney. However, the dose-dependent effect of gemigliptin on diabetic cardiomyopathy was ambivalent. The lower dose significantly attenuated left ventricular (LV) dysfunction, apoptosis, and cardiac fibrosis, but the higher dose could not protect the LV dysfunction and cardiac fibrosis.. Gemigliptin exerted non-glucoregulatory protective effects on both diabetic nephropathy and cardiomyopathy. However, high-level inhibition of DPP-4 was associated with an organ-specific effect on cardiovascular complications in type 2 diabetes.

Gemigliptin improves renal function and attenuates podocyte injury in mice with diabetic nephropathy.
    European journal of pharmacology, 2015, Aug-15, Volume: 761

    Podocytes participate in the formation and regulation of the glomerular filtration barrier. Loss of podocytes occurs during the early stages of diabetic nephropathy and impairs glomerular filtration. Dipeptidyl peptidase-4 (DPP-4) inhibitors are widely used as anti-diabetic agents in clinical practice. In this study, we showed that gemigliptin, a novel DPP-4 inhibitor, reduced podocyte apoptosis in type 2 diabetic db/db mice without reducing hyperglycemia. Gemigliptin (100mg/kg/day) was administered orally for 12 weeks in db/db mice. Blood glucose levels and albuminuria were measured. The renal cortex was collected for histological examination, and molecular assays were used to detect 8-hydroxydeoxyguanosine, advanced oxidation protein products (AOPP), the receptor for advanced glycation end products (RAGE), and integrin-linked kinase (ILK). Type 2 diabetic db/db mice exhibited albuminuria, renal histopathological changes, and podocyte loss. Administration of gemigliptin to db/db mice suppressed albuminuria, enzyme activity and expression of DPP-4, and podocyte apoptosis. The effect of gemigliptin on diabetes-induced podocyte loss was associated with the suppression of oxidative damage, AOPP accumulation, RAGE expression, and ILK expression. These results indicate the possible benefits of using gemigliptin in diabetes patients to treat renal impairment without affecting glycemic control.

Gemigliptin, a novel dipeptidyl peptidase-4 inhibitor, exhibits potent anti-glycation properties in vitro and in vivo.
    European journal of pharmacology, 2014, Dec-05, Volume: 744

    This study evaluated the inhibitory effects of gemigliptin, a highly selective dipeptidyl peptidase-4 inhibitor, on the formation of advanced glycation end products (AGEs) and AGE cross-links with proteins in in vitro as well as in type 2 diabetic db/db mice. In in vitro assay, gemigliptin dose-dependently inhibited methylglyoxal-modified AGE-bovine serum albumin (BSA) formation (IC50=11.69 mM). AGE-collagen cross-linking assays showed that gemigliptin had a potent inhibitory effect (IC50=1.39 mM) on AGE-BSA cross-links to rat tail tendon collagen, and its activity was stronger than aminoguanidine (IC50=26.4 mM). In addition, gemigliptin directly trapped methylglyoxal in a concentration-dependent manner in vitro. To determine whether gemigliptin inhibits the in vivo glycation processes, gemigliptin (100 mg/kg/day) was orally administered into type 2 diabetic db/db mice for 12 weeks. Elevated serum levels of AGEs in db/db mice were suppressed by the administration of gemigliptin. These inhibitory effects of gemigliptin on the glycation process in both in vitro and in vivo suggest its therapeutic potential for ameliorating AGE-related diabetic complications.

Gemigliptin, a novel dipeptidyl peptidase 4 inhibitor: first new anti-diabetic drug in the history of Korean pharmaceutical industry.
    Archives of pharmacal research, 2013, Volume: 36, Issue:10

    Gemigliptin, a potent, selective and long-acting DPP 4 inhibitor was developed by LG Life Sciences and approved for use in patients with type 2 diabetes mellitus by the Korean Food and Drug Administration in June 2012 under the trade name Zemiglo(®). Clinical pharmacokinetic and pharmacodynamic data suggest the efficacy and once daily dosing of gemigliptin. In clinical phase III studies, gemigliptin was efficacious as either monotherapy or combination therapy (add-on to metformin) and well tolerated in patients with type 2 diabetes. Further development of combination therapy is on-going.
