Abstract
Gemigliptin is one of the latest dipeptidyl peptidase-4 inhibitors developed by LG Life Sciences. Since the early 2000s, several randomized controlled trials (RCTs) of gemigliptin have been conducted. However, no study has directly compared its antidiabetic effects through a systematic review and meta-analysis. Therefore, in this study, we performed a systematic review and meta-analysis on RCTs. In particular, a subsequent meta-analysis was performed using Bayesian inference, and an updated quality management system model was integrated throughout our study. The mean differences and 95% confidence intervals for glycated hemoglobin (HbA1c), fasting plasma glucose (FPG), homeostatic model assessment beta cell function (HOMA-β), and low-density lipoprotein (LDL) were evaluated for the efficacy outcomes of gemigliptin as compared to those of placebo and other oral antidiabetic drugs (OADs). In conclusion, we found that gemigliptin was superior to placebo and comparable to other OADs in terms of the effect on HbA1c, FPG, HOMA-β, and LDL. Further, gemigliptin was more effective than other OADs in HbA1c and HOMA-β in Bayesian inference analysis and statistically significant to other OADs in HbA1c and HOMA-β in sensitivity analysis excluding metformin. However, to confirm the results, more studies need to be analysed and the minimum clinically important difference must be applied.

Abstract
BACKGROUND 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. METHODS 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. RESULTS 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). CONCLUSION Gemigliptin has good glycaemic efficacy and is well-tolerated over 6 months of use.

Abstract
A fixed-dose combination (FDC) of gemigliptin/metformin can improve the medication adherence in patients with type 2 diabetes mellitus (T2DM). In this study, the pharmacokinetic (PK) and pharmacodynamic (PD) profiles of gemigliptin and metformin were compared between FDC and the corresponding loose combination under fasted and fed states. A two-part, randomized, open label, single-dose, two-way crossover study was conducted in healthy male subjects. Under fasted (part 1) or fed (part 2) state, 2 FDC tablets of gemigliptin/metformin sustained release (SR) 25/500 mg or loose combination with one tablet of gemigliptin 50 mg and two tablets of metformin extended release (XR) 500 mg were orally administered in each period with a 7-day washout. Serial blood samples were collected up to 48 hours to determine the drug concentration and the dipeptidyl peptidase 4 (DPP-4) activity. The concentration-time profiles of gemigliptin and metformin were similar between FDC and loose combination in both the fasted and fed states. Geometric mean ratios and 90% confidence intervals of FDC to loose combination for area under the concentration-time curve and maximum plasma concentration of gemigliptin and metformin were within the bioequivalence range (0.8–1.25) in both states. DPP-4 activity-time profiles of FDC were comparable to that of the loose combination, showing similar area under the DPP-4 inhibition-time curve and maximum DPP-4 inhibition between FDC and loose combination, regardless of the fasted or fed state. In conclusion, the PK/PD characteristics of gemigliptin and metformin were similar in FDC tablets and loose combination both in fasted and fed states.

Abstract
AIMS 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. METHODS 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 m2 were enrolled in the main study. After 12 weeks, patients in the gemigliptin group continued to receive gemigliptin (N = 50), whereas patients in the placebo group were transitioned from placebo to linagliptin (N = 52). Each group received the indicated treatment over the subsequent 40-week period. A total of 102 patients consented to participate in the extension study, and 79 patients ultimately completed the study. RESULTS 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. CONCLUSIONS 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.

Abstract
The dipeptidyl peptidase-4 (DPP-4) inhibitors have facilitated the management of type 2 diabetes mellitus (T2DM) owing to their superior efficacy and safety with low incidence of adverse effects. Gemigliptin is a new member of this family of drugs, and studies have revealed certain advantages of gemigliptin use compared to its previous congeners. Besides, this drug has also been studied for the treatment of T2DM as monotherapy, in combination with metformin or other oral antidiabetic drugs and in T2DM with moderate-to-severe renal failure. In this review, we explore the published data highlighting the pharmacology, efficacy, and safety of gemigliptin along with its recommendations for use in patients with T2DM.

Abstract
AIMS 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). MATERIALS AND METHODS 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. RESULTS 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. CONCLUSIONS 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.

Abstract
AIMS 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). METHODS 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. RESULTS Baseline characteristics were comparable between the groups (mean HbA1c, 8.4% [68 mmol/mol]; age, 62.0 years; duration of type 2 diabetes, 16.3 years; estimated glomerular filtration rate, 33.3 mL/min/1.73 m2 ). At Week 12, the adjusted mean change ± standard error in HbA1c with gemigliptin was -0.82% ± 0.14% (-8.9 ± 1.5 mmol/mol), whereas it was 0.38% ± 0.14% (4.2 ± 1.5 mmol/mol) with placebo (significant between-group difference, P < .001). Other glycaemic control parameters showed beneficial changes as well. Body weight change (gemigliptin, -0.3 kg; placebo, -0.2 kg) was not significant. In the gemigliptin group, the mean decrease in urinary albumin creatinine ratio (UACR) was significant, both in patients with microalbuminuria (-41.9 mg/g creatinine, P = .03) and macroalbuminuria (-528.9 mg/g creatinine, P < .001). Drug-related adverse events were similar with gemigliptin and placebo (15% and 12%, respectively). CONCLUSIONS 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.

Evogliptin is a novel potent and selective dipeptidyl peptidase-4 (DPP-4) inhibitor. The aim of the present study was to evaluate the pharmacokinetic (PK) and pharmacodynamic (PD) characteristics of evogliptin in participants with renal impairment (RI). An open-label, parallel-group clinical study was conducted in participants with mild, moderate and severe RI and in matched participants with normal renal function (NRF). A single oral 5-mg dose of evogliptin was administered and serial blood and urine samples were obtained to assess the PK and PD characteristics of evogliptin. Baseline urine samples were collected to evaluate endogenous CYP3A metabolic markers. The plasma exposure to evogliptin and degree of DPP-4 activity inhibition increased with decreasing renal function. The mean areas under the concentration-time curves from 0 to 120 hours were increased 1.2-, 1.8- and 1.98-fold in the mild, moderate and severe RI groups, respectively, compared with the NRF group. The levels of CYP3A metabolic markers were lower in the RI group than in the NRF group. The increase in the plasma concentration of evogliptin is unlikely to result in changes in its efficacy or safety, considering the results of previous clinical studies.

Abstract
Dipeptidyl peptidase-4 (DPP-4) inhibitors are a new class of oral antidiabetic agent for the treatment of type 2 diabetes mellitus. They increase endogenous levels of incretin hormones, which stimulate glucose-dependent insulin secretion, decrease glucagon secretion, and contribute to reducing postprandial hyperglycemia. Although DPP-4 inhibitors have similar benefits, they can be differentiated in terms of their chemical structure, pharmacology, efficacy and safety profiles, and clinical considerations. Gemigliptin (brand name: Zemiglo), developed by LG Life Sciences, is a potent, selective, competitive, and long acting DPP-4 inhibitor. Various studies have shown that gemigliptin is an optimized DPP-4 inhibitor in terms of efficacy, safety, and patient compliance for treatment of type 2 diabetes mellitus. In this review, we summarize the characteristics of gemigliptin and discuss its potential benefits in clinical practice.

Abstract
Gemigliptin, a novel dipeptidyl peptidase (DPP)-4 inhibitor, is approved for use as a monotherapy or in combination therapy to treat hyperglycemia in patients with type 2 diabetes mellitus. In this study, we investigated the pharmacological profiles of gemigliptin in vitro and in vivo and compared them to those of the other DPP-4 inhibitors. Gemigliptin was a reversible and competitive inhibitor with a Ki value of 7.25±0.67nM. Similar potency was shown in plasma from humans, rats, dogs, and monkeys. The kinetics of DPP-4 inhibition by gemigliptin was characterized by a fast association and a slow dissociation rate compared to sitagliptin (fast on and fast off rate) or vildagliptin (slow on and slow off rate). In addition, gemigliptin showed at least >23,000-fold selectivity for DPP-4 over various proteases and peptidases, including DPP-8, DPP-9, and fibroblast activation protein (FAP)-α. In the rat, dog, and monkey, gemigliptin showed more potent DPP-4 inhibitory activity in vivo compared with sitagliptin. In mice and dogs, gemigliptin prevented the degradation of active glucagon-like peptide-1 by DPP-4 inhibition, which improved glucose tolerance by increasing insulin secretion and reducing glucagon secretion during an oral glucose tolerance test. The long-term anti-hyperglycemic effect of gemigliptin was evaluated in diet-induced obese mice and high-fat diet/streptozotocin-induced diabetic mice. Gemigliptin dose-dependently decreased hemoglobin A1c (HbA1c) levels and ameliorated β-cell damage. In conclusion, gemigliptin is a potent, long-acting, and highly selective DPP-4 inhibitor and can be a safe and effective drug for the long-term treatment of type 2 diabetes.

Abstract
The prevalence of chronic kidney disease (CKD) of stages 3-5 (glomerular filtration rate [GFR] <60 mL/min) is about 25-30 % in patients with type 2 diabetes mellitus (T2DM). While most oral antidiabetic agents have limitations in patients with CKD, incretin-based therapies are increasingly used for the management of T2DM. This review analyses (1) the influence of CKD on the pharmacokinetics of dipeptidyl peptidase-4 (DPP-4) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists; and (2) the efficacy/safety profile of these agents in clinical practice when prescribed in patients with both T2DM and CKD. Most DPP-4 inhibitors (sitagliptin, vildagliptin, saxagliptin, alogliptin) are predominantly excreted by the kidneys. Thereby, pharmacokinetic studies showed that total exposure to the drug is increased in proportion to the decline of GFR, leading to recommendations for appropriate dose reductions according to the severity of CKD. In these conditions, clinical studies reported a good efficacy and safety profile in patients with CKD. In contrast, linagliptin is eliminated by a predominantly hepatobiliary route. As a pharmacokinetic study showed only minimal influence of decreased GFR on total exposure, no dose adjustment of linagliptin is required in the case of CKD. The experience with GLP-1 receptor agonists in patients with CKD is more limited. Exenatide is eliminated by renal mechanisms and should not be given in patients with severe CKD. Liraglutide is not eliminated by the kidney, but it should be used with caution because of the limited experience in patients with CKD. Only limited pharmacokinetic data are also available for lixisenatide, exenatide long-acting release (LAR) and other once-weekly GLP-1 receptor agonists in current development. Several case reports of acute renal failure have been described with GLP-1 receptor agonists, probably triggered by dehydration resulting from gastrointestinal adverse events. However, increasing GLP-1 may also exert favourable renal effects that could contribute to reducing the risk of diabetic nephropathy. In conclusion, the already large reassuring experience with DPP-4 inhibitors in patients with CKD offers new opportunities to the clinician, whereas more caution is required with GLP-1 receptor agonists because of the limited experience in this population.
