Abstract
Introduction The CAPTURE study estimated the global prevalence of established cardiovascular disease (CVD) and characterized the usage of glucose-lowering agents (GLAs) in adults with type 2 diabetes (T2D) across 13 countries. The purpose of this secondary analysis of data from the Japanese sites within CAPTURE (NCT03786406, NCT03811288) was to provide data about medication usage stratified by CVD status among Japanese participants with T2D. Materials and methods Data on GLA usage (including those with proven cardiovascular [CV] benefits) in Japanese participants with T2D managed in clinics or hospitals were collected and stratified by CVD subgroups. Results There were 800 Japanese participants in the CAPTURE study (n = 502 [no CVD group], n = 298 [CVD group], n = 268 [atherosclerotic CVD subgroup]). Oral antidiabetic agents and insulin were used by 88.5% and 23.4%, respectively, of participants overall. Among participants with established CVD, dipeptidyl peptidase-4 inhibitors (65.1%) were most frequently used, followed by biguanides (50.7%) and insulins (26.2%). The pattern was similar among participants with atherosclerotic CVD. A lower proportion of participants in the CVD group used glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and sodium-glucose cotransporter-2 inhibitors (SGLT-2is) with proven CV benefits versus the no CVD group (GLP-1 RAs: 7.0% vs. 8.6%; SGLT-2is: 13.4% vs. 19.1%). Conclusion This analysis of the CAPTURE study provided a comprehensive overview of prescription patterns for the treatment of T2D in Japan. Use of GLAs with proven CV benefit was low, even in participants with established CVD, which was comparable to the findings from the global cohort.

Abstract
Diabetes mellitus (DM) is a chronic metabolic disorder, with type 2 diabetes (T2DM) significantly impacting the cardiovascular (CV) system. Our comprehensive study on the cardiovascular effects of liraglutide, conducted concurrently with the formulation of diabetes treatment guidelines, aims to provide healthcare providers and patients with reassurance regarding the safety and effectiveness of liraglutide. From the beginning until August 20, 2023, we conducted searches in databases including PubMed, Web of Science, Embase, Cochrane Library, Scopus, and Google Scholar. These searches aimed to identify studies comparing liraglutide to control in terms of symptom resolution among patients with T2DM. For all relevant outcomes, we calculated risk ratios along with their corresponding 95% confidence intervals. Thirteen randomized controlled trials (RCTs) were included in this analysis. The results demonstrated a significant reduction in the risk of major adverse cardiovascular events (MACE), myocardial infarction, CV mortality, and all-cause mortality. No significant difference was found between the liraglutide and control groups for the outcome of stroke. However, sensitivity analysis revealed a significant reduction in the risk of stroke among patients taking liraglutide. Our comprehensive meta-analysis strongly supports the use of liraglutide for managing cardiovascular disease (CVD) due to its established safety and effectiveness. Further RCTs and meta-analyses are needed to more thoroughly evaluate liraglutide's therapeutic potential, with the aim of enhancing the quality of life for those with CVD.

Systematic review and meta-analysis of head-to-head trials comparing sulfonylureas and low hypoglycaemic risk antidiabetic drugs. BMC Endocr Disord 2022; 22:251. [PMID: 36261824 PMCID: PMC9580135 DOI: 10.1186/s12902-022-01158-5] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/02/2021] [Accepted: 09/27/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Safety of sulfonylurea drugs in the treatment of Type 2 Diabetes is still under debate. The aim of this study was to compare the all-cause mortality and cardiovascular adverse events of sulfonylureas and drugs with a low risk for hypoglycaemia in adults with type 2 diabetes. METHODS Systematic review and meta-analysis of randomised controlled trials. DATA SOURCES MEDLINE (PubMed, OVID), Embase, Cochrane Central Register of Controlled Trials, CINAHL, WOS and Lilacs. STUDY SELECTION Randomised controlled head-to-head trials that compared sulfonylureas with active control with low hypoglycaemic potential in adults (≥ 18 years old) with type 2 diabetes published up to August 2015. The drug classes involved in the analysis were metformin, dipeptidyl peptidase-4 (DPP-4) inhibitors, sodium-glucose co-transporter-2 (SGLT-2) inhibitors and glucagon-like peptide-1 (GLP-1) receptor agonists. OUTCOMES The primary endpoint was all-cause mortality. The secondary endpoints were MACE, cardiovascular events and severe hypoglycaemia. SYNTHESIS OF RESULTS Two reviewers checked study eligibility, independently extracted data and assessed quality with disagreements resolved through discussion. We assessed the risk of bias of the included studies using the Cochrane risk of bias tool for randomized trials v2. Pooled odds ratios (ORs) were estimated by using fixed effects model. The study is registered on PROSPERO (26/05/2016 CRD42016038780). RESULTS Our final analysis comprised 31 studies (26,204 patients, 11,711 patients given sulfonylureas and 14,493 given comparator drugs). In comparison to drugs with low hypoglycaemic potential, sulfonylureas had higher odds for all-cause mortality (OR 1.32, 95% CI 1.00-1.75), MACE (OR 1.32, 95% CI 1.07-1.61), myocardial infarction (fatal and non-fatal) (OR 1.67, 95% CI 1.17-2.38) and hypoglycaemia (OR 5.24, 95% CI 4.20-6.55). Subsequent sensitivity analysis revealed differences in the effect of sulfonylureas, with an increased risk of all-cause mortality with glipizide but not the other molecules. CONCLUSION Our meta-analysis raises concern about the safety of SUs compared to alternative drugs involved in current analysis. Important differences may exist within the drug class, and glimepiride seems to have best safety profile.

Lancet Diabetes Endocrinol 2022; 10:623-633. [PMID: 35914543 DOI: 10.1016/s2213-8587(22)00188-7] [Citation(s) in RCA: 74] [Impact Index Per Article: 37.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Revised: 05/29/2022] [Accepted: 05/30/2022] [Indexed: 12/21/2022]
Abstract
BACKGROUND As the disease progresses, many patients with type 2 diabetes have difficulty in reaching treatment goals. We aimed to assess the efficacy and safety of tirzepatide, a novel GIP and GLP-1 receptor agonist, compared with dulaglutide in Japanese patients with type 2 diabetes. METHODS This multicentre, randomised, double-blind, parallel, active-controlled, phase 3 trial was conducted in 46 medical research centres and hospitals in Japan. Adults aged 20 years or older with type 2 diabetes who had discontinued oral antihyperglycaemic monotherapy or were treatment-naïve were included. Participants were randomly assigned (1:1:1:1) to receive tirzepatide (5, 10, or 15 mg) or dulaglutide (0·75 mg) once per week using a computer-generated random sequence with an Interactive Web Response System. Participants were stratified based on baseline HbA1c (≤8·5% or >8·5%), baseline BMI (<25 or ≥25 kg/m2), and washout of antidiabetic medication. Participants, investigators, and the sponsor were masked to treatment assignment. The starting dose of tirzepatide was 2·5 mg once per week for 4 weeks, which was then increased to 5 mg in the tirzepatide 5 mg treatment group. For the tirzepatide 10 and 15 mg treatment groups, increases by 2·5 mg occurred once every 4 weeks until the assigned dose was reached. The primary endpoint was mean change in HbA1c from baseline at week 52 measured in the modified intention-to-treat population. This trial is registered with ClinicalTrials.gov, NCT03861052. FINDINGS Between May 7, 2019, and March 31, 2021, 821 participants were assessed for study eligibility and 636 were randomly assigned to receive at least one dose of tirzepatide 5 mg (n=159), 10 mg (n=158), or 15 mg (n=160), or dulaglutide 0·75 mg (n=159). 615 (97%) participants completed the study and 21 (3%) discontinued. Participants had a mean age of 56·6 years (SD 10·3) and were mostly male (481 [76%]). At week 52, HbA1c decreased from baseline by a least squares mean of -2·4 (SE 0·1) for tirzepatide 5 mg, -2·6 (0·1) for tirzepatide 10 mg, -2·8 (0·1) for tirzepatide 15 mg, and -1·3 (0·1) for dulaglutide. Estimated mean treatment differences versus dulaglutide were -1·1 (95% CI -1·3 to -0·9) for tirzepatide 5 mg, -1·3 (-1·5 to -1·1) for tirzepatide 10 mg, and -1·5 (-1·71 to -1·4) for tirzepatide 15 mg (all p<0·0001). Tirzepatide was associated with dose-dependent reductions in bodyweight with a least square mean difference of -5·8 kg (SE 0·4; -7·8% reduction) for 5 mg, -8·5 kg (0·4; -11·0% reduction) for 10 mg, and -10·7 kg (0·4; -13·9% reduction) for 15 mg of tirzepatide compared with -0·5 kg (0·4; -0·7% reduction) for dulaglutide. The most common treatment-emergent adverse events were nausea (19 [12%] participants in the 5 mg group vs 31 [20%] in the 10 mg group vs 32 [20%] in the 15 mg group all receiving tirzepatide vs 12 (8%) in the group receiving dulaglutide), constipation (24 [15%] vs 28 [18%] vs 22 [14%] vs 17 [11%]), and nasopharyngitis (29 [18%] vs 25 [16%] vs 22 [14%] vs 26 [16%]). The most frequent adverse events were gastrointestinal (23 [4%] of 636). INTERPRETATION Tirzepatide was superior compared with dulaglutide for glycaemic control and reduction in bodyweight. The safety profile of tirzepatide was consistent with that of GLP-1 receptor agonists, indicating a potential therapeutic use in Japanese patients with type 2 diabetes. FUNDING Eli Lilly and Company.

Abstract
Aims/Introduction The present trial compared the efficacy and safety of once‐daily liraglutide 1.8 mg with liraglutide 0.9 mg in Japanese patients with type 2 diabetes to assess the incremental effects of liraglutide 1.8 mg in those who exhibited an inadequate response to 0.9 mg. Materials and Methods This 26‐week randomized trial (NCT02505334) enrolled Japanese adults with type 2 diabetes across 47 sites in Japan. Participants with glycated hemoglobin (HbA1c) 7.5–10.0% were included and those on insulin treatment were excluded. Participants discontinued pre‐trial oral antidiabetic drug and initiated liraglutide 0.9 mg for a 12‐week run‐in period, after which those with HbA1c ≥7.0% (466) were randomized (1:1) to two treatment arms: continuing liraglutide 0.9 mg or dose escalation to 1.8 mg. The change from baseline in HbA1c (primary endpoint) and treatment‐emergent adverse events (secondary endpoint) were measured at the end of 26 weeks. Results After 26 weeks of treatment, liraglutide 1.8 mg was more effective compared with 0.9 mg in lowering HbA1c levels, with an estimated treatment difference of −0.40% (95% confidence interval [CI] −0.55, −0.24; P < 0.0001). Liraglutide 1.8 mg was associated with significantly greater odds of participants reaching HbA1c <7.0% (estimated odds ratio [EOR] 3.87; 95% CI 2.12, 7.08; P < 0.0001) and ≤6.5% (EOR 3.78; 95% CI 1.36, 10.54; P = 0.0109) compared with 0.9 mg. Both doses were well tolerated. Conclusions Liraglutide 1.8 mg had better efficacy in improving HbA1c levels after 26 weeks treatment vs 0.9 mg in Japanese patients, with both doses well tolerated.

Abstract
UNLABELLED The association between glucagon-like peptide-1 (GLP-1) receptor agonists and the risk of various kinds of thyroid disorders remains uncertain. We aimed to evaluate the relationship between the use of GLP-1 receptor agonists and the occurrence of 6 kinds of thyroid disorders. We searched PubMed (MEDLINE), EMBASE, the Cochrane Central Register of Controlled Trials (CENTRAL) and Web of Science from database inception to 31 October 2021 to identify eligible randomized controlled trials (RCTs). We performed meta-analysis using a random-effects model to calculate risk ratios (RRs) and 95% confidence intervals (CIs). A total of 45 trials were included in the meta-analysis. Compared with placebo or other interventions, GLP-1 receptor agonists' use showed an association with an increased risk of overall thyroid disorders (RR 1.28, 95% CI 1.03-1.60). However, GLP-1 receptor agonists had no significant effects on the occurrence of thyroid cancer (RR 1.30, 95% CI 0.86-1.97), hyperthyroidism (RR 1.19, 95% CI 0.61-2.35), hypothyroidism (RR 1.22, 95% CI 0.80-1.87), thyroiditis (RR 1.83, 95% CI 0.51-6.57), thyroid mass (RR 1.17, 95% CI 0.43-3.20), and goiter (RR 1.17, 95% CI 0.74-1.86). Subgroup analyses and meta-regression analyses showed that underlying diseases, type of control, and trial durations were not related to the effect of GLP-1 receptor agonists on overall thyroid disorders (all P subgroup > 0.05). In conclusion, GLP-1 receptor agonists did not increase or decrease the risk of thyroid cancer, hyperthyroidism, hypothyroidism, thyroiditis, thyroid mass and goiter. However, due to the low incidence of these diseases, these findings need to be examined further.

Abstract
Background: Liraglutide was administered to patients with type 2 diabetes, and its effects on estimated glomerular filtration rate (eGFR) slopes and albuminuria were retrospectively evaluated. Methods: This study included 568 patients with type 2 diabetes who received liraglutide therapy (up to 0.9 mg/day) >1 year and were followed-up for a maximum of 2 years before and 7 years after treatment. The decline in renal function was estimated as the slope of the individual linear regression line of eGFR over the follow-up time. Spot urine samples were collected to measure albuminuria, which were calculated using creatinine levels. In addition, HbA1c, body weight, blood pressure, and heart rate were monitored. Results: The mean liraglutide treatment period was 3.1 ± 2.0 years. The mean baseline eGFR slope [mL/(min ·1.73 m2·year)] was -2.75 ± 6.04. After liraglutide treatment, the mean eGFR slope significantly improved (-1.42 ± 4.30, P < 0.01). This effect appeared more pronounced for baseline eGFRs <45 mL/(min ·1.73 m2). Albuminuria, HbA1c, body weight, and systolic blood pressure levels were significantly reduced after treatment with liraglutide for 1 year, whereas diastolic blood pressure and heart rates were increased. Conclusions: Patients treated with liraglutide experienced a significantly slower annual decline in kidney function. The benefit appeared more pronounced in patients with the development and progression of diabetic kidney disease. These results suggest that the benefits of liraglutide on kidney function identified in clinical trials appear to be well generalizable to clinical practice.

Abstract
INTRODUCTION Glucagon-like peptide (GLP)-1 receptor agonists are glucose-lowering agents associated with weight loss, cardiovascular benefits, and low hypoglycemic risk and are recommended by recent guidelines as first-line therapy for some patients with type 2 diabetes (T2D). This post hoc analysis of the AWARD-CHN1 study compared the efficacy and safety of once-weekly dulaglutide with glimepiride in oral antihyperglycemic medication (OAM)-naïve Chinese patients with T2D. METHODS AWARD-CHN1 was a phase 3, double-blind study with 737 patients randomized 1:1:1 to once-weekly dulaglutide (1.5 or 0.75 mg) or glimepiride (1-3 mg/day). This is a post hoc analysis of AWARD-CHN1 based on mixed-model repeated measures using a modified intent-to-treat analysis set with only the OAM-naïve Chinese population. RESULTS There were 264 OAM-naïve Chinese patients included in this analysis (dulaglutide 1.5 mg, n = 87; dulaglutide 0.75 mg, n = 90; glimepiride, n = 87). A greater glycated hemoglobin (HbA1c) reduction from baseline was observed with dulaglutide 1.5 mg and 0.75 mg compared to glimepiride (- 2.02% and - 1.84% vs - 1.37%, respectively; both P < 0.001). Significantly more patients in dulaglutide 1.5 mg and 0.75 mg groups achieved HbA1c targets < 7.0% compared to glimepiride (86.2% and 81.1% vs 65.5%; P = 0.002 and P = 0.026, respectively). Beta cell function was significantly increased for dulaglutide groups compared to glimepiride. Mean body weight was significantly reduced for dulaglutide 1.5 mg and 0.75 mg compared to glimepiride (- 1.40 kg and - 0.96 kg vs + 0.73 kg, respectively; both P < 0.001). Through 26 weeks, 7.9%, 4.2%, and 18.2% of patients reported hypoglycemia, and 40.4%, 23.2%, and 8.0% of patients reported at least one gastrointestinal treatment emergent adverse event, in dulaglutide 1.5 mg, 0.75 mg, and glimepiride groups, respectively. CONCLUSIONS In this post hoc analysis, dulaglutide was effective in reducing both HbA1c and weight with favorable tolerability and safety profile, which is consistent with results seen in larger international dulaglutide monotherapy studies.

Lancet Diabetes Endocrinol 2020; 8:392-406. [PMID: 32333876 DOI: 10.1016/s2213-8587(20)30074-7] [Citation(s) in RCA: 82] [Impact Index Per Article: 20.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/26/2019] [Revised: 02/19/2020] [Accepted: 02/25/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND New glucose-lowering medications need to be investigated in east Asian populations, as the clinical characteristics of type 2 diabetes differ between western and east Asian patients. The PIONEER 10 study aimed to evaluate the safety and efficacy of oral semaglutide versus dulaglutide in Japanese patients with type 2 diabetes. METHODS PIONEER 10 was an open-label, randomised, active-controlled, phase 3a trial done at 36 sites (clinics and university hospitals) in Japan. Patients aged 20 years and older with uncontrolled type 2 diabetes were randomly assigned (2:2:2:1) to receive once-daily oral semaglutide 3 mg, 7 mg, or 14 mg, or once-weekly subcutaneous dulaglutide 0·75 mg for 52 weeks, as an add-on to their background medication. The primary endpoint was the number of treatment-emergent adverse events over 57 weeks. Supportive secondary endpoints (not controlled for multiplicity) included mean change from baseline in HbA1c and bodyweight at 52 weeks. This trial is registered with ClinicalTrials.gov, NCT03015220. FINDINGS Between Jan 10, and May 30, 2017, 492 patients were screened and 458 were randomly assigned to oral semaglutide 3 mg (n=131), 7 mg (n=132), or 14 mg (n=130), or dulaglutide 0·75 mg (n=65). 448 (98%) patients completed the trial. Adverse events occurred in 101 (77%) of 131 patients with oral semaglutide 3 mg, 106 (80%) of 132 with oral semaglutide 7 mg, 111 (85%) of 130 with oral semaglutide 14 mg, and 53 (82%) of 65 with dulaglutide. The most common adverse events were infections and gastrointestinal events. Gastrointestinal adverse events (mostly mild and transient constipation and nausea) occurred in a dose-dependent manner with oral semaglutide. Adverse events led to premature treatment discontinuation in four (3%) of 131 patients receiving oral semaglutide 3 mg, eight (6%) of 132 receiving oral semaglutide 7 mg, eight (6%) of 130 receiving oral semaglutide 14 mg, and two (3%) of 65 receiving dulaglutide. No deaths or severe hypoglycaemic events were reported. Based on the treatment policy estimand (ie, regardless of study drug discontinuation or rescue medication use), estimated mean reductions in HbA1c from baseline (8·3%) to week 52 were -0·9 percentage points (SE 0·1) with oral semaglutide 3 mg, -1·4 percentage points (0·1) with oral semaglutide 7 mg, -1·7 percentage points (0·1) with oral semaglutide 14 mg, and -1·4 percentage points (0·1) with dulaglutide (estimated treatment difference -0·3% [95% CI -0·6 to -0·1] for oral semaglutide 14 mg vs dulaglutide; p=0·0170). Estimated mean changes in bodyweight from baseline (72·1 kg) to week 52 were 0·0 kg (SE 0·3) with oral semaglutide 3 mg, -0·9 kg (0·3) with oral semaglutide 7 mg, -1·6 kg (0·3) with oral semaglutide 14 mg, and 1·0 kg (0·4) with dulaglutide (estimated treatment difference -2·6 kg [95% CI -3·5 to -1·6] for oral semaglutide 14 mg vs dulaglutide; p<0·0001). INTERPRETATION Oral semaglutide was well tolerated in Japanese patients with type 2 diabetes. Once-daily oral semaglutide significantly reduced HbA1c (14 mg dose) and bodyweight (7 mg and 14 mg doses) versus weekly subcutaneous dulaglutide 0·75 mg by week 52. FUNDING Novo Nordisk.

Abstract
BACKGROUND Given the unique phenotype of type 2 diabetes in Japanese patients, novel therapies such as oral semaglutide require evaluation in this population. PIONEER 9 aimed to assess the dose-response of oral semaglutide and to compare the efficacy and safety of oral semaglutide with placebo and a subcutaneous GLP-1 receptor agonist in a Japanese population. METHODS PIONEER 9 was a 52-week, phase 2/3a, randomised, controlled trial done at 16 sites (clinics and university hospitals) in Japan. Japanese patients aged 20 years or older with uncontrolled type 2 diabetes managed by diet or exercise or with oral glucose-lowering drug monotherapy (washed out) were randomly assigned (1:1:1:1:1) to receive double-blind once-daily oral semaglutide (3 mg, 7 mg, or 14 mg) or placebo, or open-label subcutaneous once-daily liraglutide 0·9 mg. The primary endpoint was change in HbA1c from baseline to week 26 with the trial product (primary) estimand (which assumes all patients remained on trial product without rescue medication use) in all randomly assigned patients. This trial is registered with ClinicalTrials.gov, NCT03018028. FINDINGS Between Jan 10, and July 11, 2017, 243 patients were randomly assigned to oral semaglutide 3 mg (n=49), 7 mg (n=49), or 14 mg (n=48), or placebo (n=49), or to liraglutide 0·9 mg (n=48). Changes in HbA1c from baseline (mean 8·2%) to week 26 were dose-dependent with oral semaglutide (mean change -1·1% [SE 0·1] for oral semaglutide 3 mg, -1·5% [0·1] for 7 mg, and -1·7% [0·1] for 14 mg), -0·1% (0·1) with placebo, and -1·4% (0·1) with liraglutide 0·9 mg. Estimated treatment differences for change in HbA1c compared with placebo were -1·1 percentage points (95% CI -1·4 to -0·8; p<0·0001) for oral semaglutide 3 mg, -1·5 percentage points (-1·7 to -1·2; p<0·0001) for oral semaglutide 7 mg, and -1·7 percentage points (-2·0 to -1·4; p<0·0001) for oral semaglutide 14 mg. Estimated treatment differences for change in HbA1c compared with liraglutide 0·9 mg were 0·3 percentage points (95% CI -0·0 to 0·6; p=0·0799) for oral semaglutide 3 mg, -0·1 percentage points (-0·4 to 0·2; p=0·3942) for oral semaglutide 7 mg, and -0·3 percentage points (-0·6 to -0·0; p=0·0272) for oral semaglutide 14 mg. Gastrointestinal events, predominantly of mild or moderate severity, were the most frequently reported class of adverse event with oral semaglutide: constipation was most common, occurring in five to six (10-13%) patients with oral semaglutide, three (6%) with placebo, and nine (19%) with liraglutide 0·9 mg. INTERPRETATION This study showed that oral semaglutide provides significant reductions in HbA1c compared with placebo in a dose-dependent manner in Japanese patients with type 2 diabetes, and has a safety profile consistent with that of GLP-1 receptor agonists.

Abstract
OBJECTIVES The introduction of liraglutide in the treatment of patients with type 2 diabetes already taking insulin is still subject to discussion in terms of timing and benefits. Gradually intensive insulin therapy is hastily prescribed. Switching from multiple insulin injection (MII) to insulin and liraglutide is evaluated in this study. METHODOLOGY We studied 92 patients with type 2 diabetes previously under MII, C-peptide ≥ 1.5 ng/ml, divided into a group with reasonable glycemic control [RC: HbA1c < 8% (64 mmol/mol)] and another with a poor control [PC: HbA1c ≥ 8%, (64 mmol/mol)] after introduction of liraglutide and insulin therapy. RESULTS Except for HbA1c, there were no statistical differences between RC and PC groups. Basal insulin doses were adjusted to achieve the fasting plasma glucose of 90-120 mg/dl. HbA1c was significantly improved in both groups, from 9.6% ± 1.6 (81 mmol/mol) and 7.0% ± 0.6 (53 mmol/mol) to 8.0% ± 1.5 (64 mmol/mol) and 6.8 ± 0.5% (51 mmol/mol). Reduction of body weight was significant only in RC (from 70 ± 16 kg to 68 ± 16 kg, p < 0.01). All patients from RC group and 58% of PC group reached HbA1c < 8% without hypoglycemia. CONCLUSION This observation persuades us to propose the liraglutide and insulin combination to patients with C-peptide ≥ 1.5 ng/ml, regardless of the HbA1c.

Abstract
Japan's guidelines emphasize tailored therapy, but do not guide physicians on the use of a specific regimen in drug-naive patients. The role of long-term initial therapy could be important in key elements of diabetes treatment, such as continuation of the initially prescribed drug. We investigated the frequency of occurrence to treatment intensification after the initiation of metformin or dipeptidyl peptidase-4 inhibitor treatment. In multivariable-adjusted Cox proportional hazards models, initiation of dipeptidyl peptidase-4 inhibitor was associated with a low hazard of intensification. The findings of this survey showed that dipeptidyl peptidase-4 inhibitors were the preferred first-line treatment in Japan because of the high continuation rate of the treatment and hemoglobin A1c-lowering effect. This information would provide guidance in selecting initial hypoglycemic drugs to optimize the treatment of type 2 diabetes mellitus patients in Japan and Asia.

Abstract
BACKGROUND Liraglutide is a novel, long-acting glucagon-like peptide-1 (GLP-1) analogue used to treat type 2 diabetes mellitus. However, the cardiovascular safety and benefits of liraglutide treatment on type 2 diabetes patients remain in debate. In this study, we aimed to examine the overall cardiovascular outcomes of liraglutide in patients with type 2 diabetes. METHODS In this systematic review and meta-analysis, we searched the PubMed, Embase, and Web of Knowledge databases up to September 1st, 2017 for randomized trials in which type 2 diabetes patients were assigned to liraglutide and placebo or other comparators groups. RESULTS Eight studies fulfilled the eligibility criteria for inclusion and 14,608 patients were analyzed in this systematic review and meta-analysis. We found patients in the liraglutide group had a lower risk of major cardiovascular events (MACE) (RR = 0.89, 95% CI: 0.82-0.96, P = .002), acute myocardial infarction (AMI) (RR = 0.85, 95% CI: 0.74-0.99, P = .036), all-cause death (RR = 0.84, 95% CI: 0.74-0.96, P = .009), and cardiovascular death (RR = 0.77, 95% CI: 0.65-0.91, P = .002) than all comparator groups. However, liraglutide treatment did not decrease incidence of stroke (RR = 0.86, 95% CI: 0.70-1.04, P = .124). But among the MACE subgroups analysis, a significant reduction of MACE with liraglutide was only observed in placebo-controlled trials (RR = 0.89, 95% CI: 0.83-0.96, P = .004) but not in studies concerning other comparators (RR = 0.58, 95% CI: 0.29-1.16, P = .122). CONCLUSIONS In conclusion, our results suggest that liraglutide treatment decreases the risk of MACE, AMI, all-cause death and cardiovascular death among patients with type 2 diabetes.

Abstract
PURPOSE Some preliminary studies reported a link between GLP-1 receptor agonists (GLP-1RAs) and thyroid/pancreatic neoplasms, while its human relevance remained undetermined. The present meta-analysis was performed to collect information on cancers associated with GLP-1RAs in patients with type 2 diabetes mellitus (T2DM). METHODS Medline, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science and ClinicalTrials.gov were extensively searched to identify randomized controlled trials that reported cancer events in T2DM patients treated with GLP-1RAs for at least 52 weeks, up to March 18, 2019. Odds ratio (OR) with 95% Confidence Interval (CI) was calculated for overall cancer (primary outcome), thyroid and pancreatic cancer. RESULTS A total of 37 eligible trials were identified. The OR for overall cancer associated with GLP-1RAs was 1.03 (95% CI 0.95-1.12; p = 0.41) compared with comparators. Subgroup analyses showed that treatment with albiglutide was associated with a lower risk of overall cancer (OR 0.76 [95% CI 0.60-0.97]; p = 0.03), and no elevated risk of overall cancer was identified for other GLP-1RAs. No significant differences in the risks of thyroid nor pancreatic cancer were disclosed between GLP-1RAs and comparators. CONCLUSIONS This meta-analysis did not suggest any increased risk of cancers associated with GLP-1RAs use in T2DM. The reduction in the risk of overall cancer associated with albiglutide needs to be examined further.

Liraglutide Reduces Visceral and Intrahepatic Fat Without Significant Loss of Muscle Mass in Obese Patients With Type 2 Diabetes: A Prospective Case Series. J Clin Med Res 2019; 11:219-224. [PMID: 30834046 PMCID: PMC6396779 DOI: 10.14740/jocmr3647] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2019] [Accepted: 01/24/2019] [Indexed: 01/17/2023] Open
Abstract
Background Glucagon-like peptide-1 receptor agonists have been reported to reduce body fat as well as improving glycemic control in obese patients with type 2 diabetes. However, the maximum dose of liraglutide is limited to 0.9 mg in Japan, while the international dose is 1.8 mg; and the effect of this low dose on body composition has not been assessed in detail. Accordingly, this study was performed to evaluate the effect of liraglutide on body composition when administered at 0.9 mg once daily for 24 weeks. Methods Nine patients were enrolled and started liraglutide at 0.3 mg once daily, which was titrated to 0.9 mg once daily after 1 - 2 weeks and continued for 24 weeks. To comprehensively investigate changes of body composition, the body fat and muscle weight were determined by dual energy absorptiometry, visceral fat volume (VFV) and abdominal subcutaneous fat volume (SFV) were measured by abdominal computed tomography (CT), and the intrahepatic lipid content (IHL) was assessed by proton magnetic resonance spectroscopy. Measurements were obtained before starting liraglutide therapy and after 12 and 24 weeks of treatment. Results Fasting plasma glucose was significantly reduced from 127 ± 22 to 101 ± 14 mg/dL at 24 weeks and hemoglobin A1c (HbA1c) showed significant reduction from 6.4±0.9% to 5.2±0.5%. Body weight was reduced from 103.4 ± 14.7 to 97.0 ± 12.4 kg (mean reduction: 11.7%) and BMI decreased from 37.4 ± 6.4 to 35.0 ± 5.3 kg/m2 (mean reduction: 5.8%). Furthermore, VFV and IHL decreased from 5,192 ± 1,730 to 4,513 ± 1,299 cm3 (mean reduction: 11.9%) and 32.1±12.6% to 15.2±9.2% (mean reduction: 49.2%), respectively, but SFV did not change. Moreover, the fat index was reduced from 14.8 ± 4.4 to 12.9 ± 3.4 kg/m2 (mean reduction: 10.9%), but the skeletal muscle index did not change. Conclusions In obese Japanese drug-naive patients who had type 2 diabetes, treatment with liraglutide (0.9 mg once daily for 24 weeks) reduced body fat, especially visceral fat and intrahepatic fat, while having no significant effect on skeletal muscle.

Abstract
BACKGROUND Several clinical trials have studied the effects of glucagon-like peptide-1 receptor agonists (GLP-1RAs) on glycometabolism and cardiovascular risk factors since they were identified. Because of their cardiovascular benefits and efficacy in lowering glucose, GLP-1RAs are becoming increasingly important in clinical therapy for patients with or without pathoglycaemia. The aim of this study was to assess the effect of the GLP-1RA liraglutide on blood pressure based on randomised controlled trials (RCTs). METHODS We searched PubMed for RCTs published from 2009 to 2018 comparing the effect of liraglutide on blood pressure with that of placebo in individuals with or without pathoglycaemia. RCTs in humans that included data describing blood pressure changes from baseline to the end of the trial were selected for inclusion in the meta-analysis. RESULTS A total of 18 RCTs that enrolled 7616 individuals in the liraglutide group and 6046 individuals in the control group were included in this meta-analysis. Compared with placebo, liraglutide reduced systolic blood pressure (SBP) by 3.18 mmHg (95% CI -4.32, - 2.05), P < 0.00001, but had no significant effect on diastolic blood pressure (DBP). Subgroup analysis showed that the degree of reduction in SBP was associated with the dose of liraglutide but that significance disappeared when the intervention lasted over 1 year. Liraglutide 3.0 mg/d significantly reduced DBP by 1.46 mmHg (95% CI -2.61, 0.32), P = 0.01, but liraglutide 1.8 mg/d slightly increased DBP by 0.47 mmHg (95% CI 0.11, 0.83), P = 0.01, compared with placebo. CONCLUSIONS This meta-analysis demonstrated that liraglutide significantly reduced SBP in individuals with or without pathoglycaemia compared with placebo, but the difference was no longer significant when the intervention lasted over 1 year. Moreover, the effect of liraglutide on blood pressure is associated with the dose. This finding may provide additional evidence for cardiovascular protection.

Chen YH, Huang C, Cho YM, Li P, Gu L, Wang F, Yang J, Wang WQ. Efficacy and safety of dulaglutide monotherapy compared with glimepiride in East-Asian patients with type 2 diabetes in a multicentre, double-blind, randomized, parallel-arm, active comparator, phase III trial. Diabetes Obes Metab 2018; 20:2121-2130. [PMID: 29708650 PMCID: PMC6099453 DOI: 10.1111/dom.13340] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2017] [Revised: 04/18/2018] [Accepted: 04/24/2018] [Indexed: 12/13/2022]
Abstract
AIMS To compare the efficacy and safety of once-weekly glucagon-like peptide-1 receptor agonist dulaglutide 1.5 and 0.75 mg with glimepiride in East-Asian patients with type 2 diabetes (T2D). MATERIALS AND METHODS In this phase III, multinational, multicentre, double-blind, randomized, parallel-arm, 26-week study, patients with inadequate glycaemic control were randomized 1:1:1 to once-weekly dulaglutide 1.5 or 0.75 mg or daily glimepiride (1-3 mg/d). The primary endpoint was assessment of the non-inferiority of dulaglutide (1.5 mg), as measured by change in glycated haemoglobin (HbA1c), compared with glimepiride using a 0.4% non-inferiority margin. RESULTS A total of 737 patients were randomized (dulaglutide 1.5 mg, n = 244; dulaglutide 0.75 mg, n = 248; glimepiride, n = 245). At week 26, both doses of dulaglutide were non-inferior and also superior to glimepiride for HbA1c reduction from baseline with a least squares mean difference of -6.34 mmol/mol (95% confidence interval [CI] -8.31, -4.26) or -0.58% (95% CI -0.76, -0.39) for dulaglutide 1.5 mg and -3.50 mmol/mol (95% CI -5.47, -1.42) or -0.32% (95% CI -0.50, -0.13) for dulaglutide 0.75 mg (P < .001). A greater proportion of patients in the dulaglutide 1.5 mg group achieved the HbA1c target of <53 mmol/mol (<7.0%) compared with the glimepiride group (74.1% vs 57.4%; P < .001). The mean body weight decreased (P < .005) and total hypoglycaemia rates were lower (P < .001) in the dulaglutide groups compared with the glimepiride group. The most common drug-related adverse events in both dulaglutide groups (≥5% of patients) included diarrhoea, nausea, increased lipase, decreased appetite, abdominal distension and vomiting. CONCLUSIONS Dulaglutide (both doses) demonstrated superior glycaemic control vs glimepiride, with a favourable tolerability and safety profile in East-Asian patients with T2D.

Safety and efficacy of the combination of the glucagon-like peptide-1 receptor agonist liraglutide with an oral antidiabetic drug in Japanese patients with type 2 diabetes: Post-hoc analysis of a randomized, 52-week, open-label, parallel-group trial. J Diabetes Investig 2018; 9:831-839. [PMID: 28984041 PMCID: PMC6031500 DOI: 10.1111/jdi.12759] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2017] [Revised: 09/04/2017] [Accepted: 10/01/2017] [Indexed: 11/27/2022] Open
Abstract
AIMS/INTRODUCTION The aim of the present post-hoc analysis was to investigate the safety and efficacy of liraglutide in combination with one oral antidiabetic drug (OAD) across different OAD classes. MATERIALS AND METHODS This was a post-hoc analysis using data from a 52-week, open-label, parallel-group trial, in which patients with type 2 diabetes inadequately controlled with a single OAD (α-glucosidase inhibitor, glinide, metformin or thiazolidinedione) were randomized to either pretrial OAD in combination with liraglutide 0.9 mg/day (liraglutide group) or pretrial OAD in combination with an additional OAD (additional OAD group). The primary outcome investigated in this post-hoc analysis was the incidence of adverse events. RESULTS The proportions of patients experiencing adverse events across the different groups of pretrial OADs were comparable between liraglutide and additional OAD (α-glucosidase inhibitor 74.6 vs 70.0%; glinide 93.1 vs 87.1%; metformin 91.8 vs 87.1%; thiazolidinedione 86.2 vs 96.4%, respectively). Minor hypoglycemia was infrequent (seven episodes in two patients randomized to liraglutide, and two episodes in two patients randomized to additional OAD). The mean reduction in glycated hemoglobin appeared greater with liraglutide therapy, with the estimated mean treatment difference (95% confidence interval [CI]) for liraglutide vs additional OAD ranging from -0.14%, 95% CI: -0.48 to 0.21 (-1.5 mmol/mol, 95 CI: -5.2 to 2.3) to -0.44%, 95% CI:-0.79 to -0.09 (-4.8 mmol/mol, 95% CI: -8.6 to -1.0). CONCLUSIONS The present analysis suggests that Japanese patients on OAD monotherapy might benefit from a greater improvement in glycemic control, without impacting tolerability, by combining their OAD with liraglutide rather than another OAD, regardless of which OAD monotherapy they are receiving.

Abstract
AIMS We examined whether 0.9 mg/day liraglutide plus basal insulin (Lira-basal) is superior to basal-bolus insulin therapy (BBIT) for type 2 diabetes (T2DM) without severe insulin deficiency as determined by glucagon stimulation. METHODS Fifty patients receiving BBIT were enrolled in this 24-week, prospective, randomized, open-labeled study. After excluding subjects with fasting C-peptide immunoreactivity (CPR) < 1.0 ng/mL and CPR increase < 1.0 ng/mL at 6 min post glucagon injection, 25 were randomly allocated to receive Lira-basal (n = 12) or continued BBIT (n = 13). Primary endpoint was change in HbA1c. Secondary endpoints were changes in body weight (BW), 7-point self-monitored blood glucose (SMBG), and Diabetes Treatment Satisfaction Questionnaire status (DTSQs) scores. RESULT The Lira-basal group demonstrated reduced HbA1c, whereas the BBIT group showed no change. BW was reduced in the Lira-basal group but increased in the BBIT group. The Lira-basal group also exhibited significantly reduced pre-breakfast and pre-lunch SMBG. DTSQs scores improved in the Lira-basal group but not the BBIT group. Plasma lipids, liver function, and kidney function were not significantly changed in either group. CONCLUSIONS Lira-basal therapy is superior to BBIT for T2DM without severe insulin deficiency. This study was registered with UMIN Clinical Trials Registry (UMIN000028313).

Safety, tolerability and efficacy of lixisenatide as monotherapy in Japanese patients with type 2 diabetes mellitus: An open-label, multicenter study. J Diabetes Investig 2018; 9:108-118. [PMID: 28195447 PMCID: PMC5754539 DOI: 10.1111/jdi.12646] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/05/2016] [Revised: 02/06/2017] [Accepted: 02/08/2017] [Indexed: 12/16/2022] Open
Abstract
AIM/INTRODUCTION To assess the overall safety of lixisenatide monotherapy in Japanese patients with type 2 diabetes mellitus. MATERIALS AND METHODS Patients with type 2 diabetes mellitus, previously treated with ≤1 oral antidiabetic drug, were enrolled in an uncontrolled, open-label, single-arm study over 24 and 52 weeks. Any oral antidiabetic drug treatment was stopped at the start of the 6-week run-in period. From baseline, patients received once-daily lixisenatide monotherapy (10 μg for 1 week, 15 μg for 1 week, 20 μg thereafter) for 52 weeks (first 140 patients enrolled) or 24 weeks (subsequently enrolled patients). The primary end-point was safety over 24 and 52 weeks. Secondary efficacy end-points included absolute change in glycated hemoglobin, fasting plasma glucose and bodyweight from baseline. RESULTS Of 428 patients screened, 361 and 140 were treated for 24 and 52 weeks, respectively; 88.4 and 90.0% completed treatment. During the 24- and 52-week treatment periods, 268/361 (74.2%) and 117/140 (83.6%) patients, respectively, had treatment-emergent adverse events; the most frequently reported was nausea (33.2 and 31.4%, respectively). The risk of severe hypoglycemia was low; only one case was reported. Lixisenatide treatment resulted in a decrease in mean glycated hemoglobin A1c (-0.98 and -0.86%), fasting plasma glucose (-1.05 and -0.85 mmol/L), and bodyweight (-1.33 and -1.48 kg) for the 24- and 52-week treatment periods, respectively. CONCLUSIONS Once-daily lixisenatide monotherapy was associated with a safety profile in line with the glucagon-like peptide-1 receptor agonist class, and improved glycemic control in Japanese patients with type 2 diabetes mellitus.

Glucagon-like peptide-1 mimetics, optimal for Asian type 2 diabetes patients with and without overweight/obesity: meta-analysis of randomized controlled trials. Sci Rep 2017; 7:15997.

Abstract
Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are desirable for diabetes, especially in patients with overweight/obesity. We aimed to determine whether GLP-1RAs exhibit different glucose-lowering efficacies between Asian type 2 diabetes (T2D) patients with and without overweight/obesity. Randomized controlled trials were searched in EMBASE, MEDLINE, CENTRAL, and ClinicalTrials.gov. Studies published in English with treatment duration ≥12 weeks and information on HbA1c changes were included. The studies were divided into normal body mass index (BMI) and overweight/obese groups according to baseline BMI. Among 3190 searched studies, 20 trials were included in the meta-analysis. The standardized mean differences in HbA1c change, fasting glucose change, and postprandial glucose change were equivalent between normal BMI and overweight/obese studies (p > 0.05). The relative risk of HbA1c < 6.5% target achievement in normal BMI trials (7.93; 95% confidence interval: 3.27, 19.20) was superior to that in overweight/obesity trials (2.23; 1.67, 2.97), with a significant difference (p = 0.020). Body weight loss (p = 0.572) and hypoglycemic risk(p = 0.920) were similar in the two groups. The glucose-lowering effects of GLP-1RAs were equivalent among Asian T2D patients. With their advantages for weight-loss or weight-maintenance, GLP-1RAs are optimal medicines for Asian T2D patients with and without overweight/obesity.

Effect of Long-term Incretin-Based Therapies on Ischemic Heart Diseases in Patients with Type 2 Diabetes Mellitus: A Network Meta-analysis. Sci Rep 2017; 7:15795.

Abstract
Patients with type 2 diabetes mellitus (T2DM) experience many cardiovascular complications. Several studies have demonstrated the cardioprotective effects of incretin-based therapies; however, there are few studies on the effects of long-term incretin-based therapies on cardiovascular events. Therefore, the present study conducted a systematic review and network meta-analysis to evaluate the effects of long-term incretin-based therapies on ischaemic diseases. We searched PubMed, CENTRAL, and Clinicaltrial.gov to retrieve randomised control trials reported until December 2016 and enrolled only RCTs with more than a 1-year follow-up. The network meta-analysis was performed using R Software with a GeMTC package. A total of 40 trials were included. Dipeptidyl peptidase 4 inhibitors and glucagon-like peptide-1 agonists were associated with a lower risk of myocardial infarction (MI) than were sulfonylureas (odds ratio [95% credible interval] 0.41 [0.24–0.71] and 0.48 [0.27–0.91], respectively). These results suggested that patients with T2DM receiving long-term incretin-based therapies have a lower risk of MI than do those receiving sulfonylurea-based therapy. These findings highlight the risks of cardiovascular events in patients who receive long-term incretin-based therapies, and may provide evidence for the selection of antidiabetic therapy in the future.

Abstract
BACKGROUND Randomized controlled trials (RCTs) reported that resistant dextrin (RD) exerted pleiotropic effects on humans. However, limited information is available on the effects of RD for weight loss. We conducted a systematic review with a meta-analysis to summarize the available literature and compare the efficacy of RD for weight loss with that of a placebo in overweight adults. METHODS We searched the electronic databases MEDLINE, EMBASE, The Cochrane Central Register of Controlled Trials (CENTRAL), CINAHL, Web of Science, ClincalTrials.gov, and Japana Centra Revuo Medicina (Ichushi-web) for studies from their onset to November 2016, and there was no language restriction. Trials were included if they were RCTs (1) comparing the effects of RD with a placebo in adults (18 years or older), (2) reporting body mass index, and (3) including overweight/obese subjects as defined by the authors of RCTs. The weighted mean difference with a 95% confidence interval (CI) was calculated using a random-effects model. RESULTS Of the 484 studies retrieved, 3 RCTs involving 275 subjects were included in our review. The durations of RCTs ranged between 8 and 12 weeks. All RCTs were conducted in Asian countries. RD significantly improved body mass index [mean difference -0.39 (95% CI -0.57 to -0.21) kg/m2, p < 0.01] and body weight [mean difference -0.81 (95% CI -0.93 to -0.69) kg, p < 0.01] in overweight adults. CONCLUSION Our review suggests that RD exerts beneficial effects for weight loss in overweight adults. More RCTs with different populations and longer follow-ups are needed in order to confirm that supplementation with RD has beneficial effects for weight loss in overweight adults. We consider this review to provide important information for the future submission of food with health claims.

Abstract
BACKGROUND Glucagon-like peptide-1 receptor agonists (GLP-1RAs) act by increasing insulin secretion, decreasing glucagon secretion, slowing gastric emptying, and increasing satiety. OBJECTIVE Published evidence directly comparing GLP-1RAs with other approved treatments for type 2 diabetes (T2D) was systematically reviewed. METHODS A literature search was performed using MEDLINE and Embase databases to identify papers comparing GLP-1RAs with other classes of glucose-lowering therapy in patients with T2D. RESULTS Of the 1303 papers identified, 57 met the prespecified criteria for a high-quality clinical trial or retrospective study. The efficacy and tolerability of approved GLP-1RAs (exenatide twice daily or once weekly, dulaglutide, liraglutide, lixisenatide, and albiglutide) were compared with insulin products (23 prospective studies + seven retrospective studies), dipeptidyl peptidase-4 inhibitors (11 prospective studies + three retrospective studies), sulfonylureas (nine prospective studies + one retrospective study), thiazolidinediones (five prospective studies), and metformin (two prospective studies). GLP-1RAs are effective as a second-line therapy in improving glycemic parameters in patients with T2D. Reductions in glycated hemoglobin from baseline with GLP-1RAs tended to be greater or similar compared with insulin therapy. GLP-1RAs were consistently more effective in reducing body weight than most oral glucose-lowering drugs and insulin and were associated with lower hypoglycemia risk versus insulin or sulfonylureas. GLP-1RAs improved cardiovascular risk factors, and preliminary data suggest they improve cardiovascular outcomes in patients with T2D compared with oral glucose-lowering drugs. However, results from ongoing studies are awaited to confirm these early findings. CONCLUSION This systematic review found that GLP-1RAs are an effective class of glucose-lowering drugs for T2D.

Abstract
BACKGROUND Recent cardiovascular outcome trials of incretin-based therapies (IBT) in type 2 diabetes have not demonstrated either benefit or harm in terms of major adverse cardiovascular events (MACE). Earlier meta-analyses showed conflicting results but were limited in methodology. We aimed to perform an updated meta-analysis of all available incretin therapies on the incidence of MACE plus arrhythmia and heart failure. METHODS We identified studies published through November 2014 by searching electronic databases and reference lists. We included RCTs in which the intervention group received incretin-based therapies and the control group received placebo or standard treatment; enrolled >100 participants in each group; interventions lasted >24 weeks; and reported data on one or more primary major adverse cardiovascular events endpoints plus terms for arrhythmia and heart failure. We used the Peto method for each CV event for individual IBT treatment. RESULTS In this meta-analysis of 100 RCTs involving 54,758 incretin-based therapies users and 48,175 controls, exenatide was associated with increased risk of arrhythmia (OR 2.83; 95% CI, 1.06-7.57); saxagliptin was associated with an increased risk of heart failure (OR 1.23; 95% CI, 1.03-1.46), and sitagliptin was associated with a significantly decreased risk of all cause death compared to active controls (OR 0.39, 95% CI 0.18-0.82). CONCLUSIONS In type 2 diabetes, exenatide may increase the risk of arrhythmia, and sitagliptin may reduce the risk of all cause death; however, the subgroup of patients most likely to experience harm or benefit is unclear.

Abstract
INTRODUCTION Many persons with type 1 diabetes do not achieve glycemic targets, why new treatments, complementary to insulin, are of interest. Liraglutide, a long-acting glucagon-like peptide-1 receptor agonist could be a potential pharmacological supplement to insulin. This review discusses the mechanism of actions, efficacy and safety of liraglutide as add-on to insulin in persons with type 1 diabetes. AREAS COVERED Physiological and clinical data on liraglutide in type 1 diabetes were reviewed. We searched the Cochrane library, MEDLINE and EMBASE, with the final search performed February 16, 2016. EXPERT OPINION Liraglutide as adjunct to insulin treatment reduced body weight and daily dose of insulin compared with insulin alone. The effect on HbA1c was inconsistent with mostly uncontrolled, small-scale studies reporting improvements in glycemic control. In placebo-controlled studies there was no clinically relevant effect on HbA1c. Adverse events were mostly transient gastrointestinal side effects, primarily nausea. Based on the available data, liraglutide cannot be recommended as add-on therapy to insulin in persons with type 1 diabetes with the aim to improve glycemic control. Ongoing trials in newly diagnosed patients with type 1 diabetes and in insulin pump-treated patients will help define the future role of liraglutide therapy in type 1 diabetes.

Abstract
BACKGROUND Long-term efficacy of liraglutide, a glucagon-like peptide-1 analog, on body weight and glycemic control has not been studied in Indian Type 2 diabetes mellitus (T2DM) subjects. AIM To evaluate the effect of liraglutide on glycemic control and body weight for 1 year in Indian T2DM patients. METHODS Liraglutide was prescribed to 96 obese patients with T2DM and followed up for 1 year. Clinical parameters were measured at baseline and 3, 6, 9, and 12 months. Dosage of liraglutide and other medications was adjusted according to clinical judgment. RESULTS 1 year data were available for 74 patients. Mean age was 50.9 ± 9.6 years. Mean duration of diabetes was 11.6 ± 6.3 years. Glycosylated hemoglobin (HbA1c) significantly decreased from 8.9 ± 1.3% at baseline to 7.4 ± 1.2% at 1 year. Body weight significantly declined from 98.9 ± 16.0 kg at baseline to 93.8 ± 15.0 kg at 1 year. After an initial decline, subset of patients had an increase in mean HbA1c (n = 30/74) and mean body weight (n = 33/74) after 6 months of liraglutide initiation. Baseline HbA1c and baseline body weight were positively associated with a reduction of HbA1c and body weight at 1 year, respectively. No major side effects occurred. CONCLUSION Liraglutide treatment resulted in a significant and sustained reduction in HbA1c and body weight over 1 year in Indian T2DM patients. Magnitude of reduction of HbA1c and body weight at 1 year was positively associated with baseline HbA1c and baseline weight, respectively.

Abstract
Incretin-based therapies such as glucagon-like peptide-1 (GLP-1) receptor agonists (RA) and dipeptidyl peptidase-4 (DPP-4) inhibitors have gained prominence in recent years for the treatment of type 2 diabetes (T2D). Such therapies offer the potential to stimulate endogenous insulin activity in proportion to circulating glucose levels; thereby, lowering the risk of hypoglycemic episodes. The synthetic GLP-1 RA exenatide, the human GLP-1 RA liraglutide, and the DPP-4 inhibitor sitagliptin are the first agents in their respective classes to be approved for the treatment of T2D and their efficacy and safety has been studied extensively in clinical trials. This article reviewed the efficacy of liraglutide once daily in achieving clinical guidelines-recommended glycated hemoglobin A1c levels in patients with T2D compared with exenatide twice daily, or sitagliptin once daily, based on published literature, with an aim to elucidate the preferred choice of incretin-related therapy in treating uncontrolled T2D.

Efficacy and Acceptability of Glycemic Control of Glucagon-Like Peptide-1 Receptor Agonists among Type 2 Diabetes: A Systematic Review and Network Meta-Analysis. PLoS One 2016; 11:e0154206. [PMID: 27158818 PMCID: PMC4861281 DOI: 10.1371/journal.pone.0154206] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2015] [Accepted: 04/11/2016] [Indexed: 12/26/2022] Open
Abstract
Objective To synthesize current evidence of the impact of Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) on hypoglycemia, treatment discontinuation and glycemic level in patients with type 2 diabetes. Design Systematic review and network meta-analysis. Data Sources Literature search (Medline, Embase, the Cochrane library), website of clinical trial, bibliographies of published systematic reviews. Eligibility Criteria Randomized controlled trials with available data comparing GLP-1 RAs with placebo or traditional anti-diabetic drugs in patients with type 2 diabetes. Data Synthesis Traditional pairwise meta-analyses within DerSimonian-Laird random effects model and network meta-analysis within a Bayesian framework were performed to calculate odds ratios for the incidence of hypoglycemia, treatment discontinuation, HbA1c<7.0% and HbA1c<6.5%. Ranking probabilities for all treatments were estimated to obtain a treatment hierarchy using the surface under the cumulative ranking curve (SUCRA) and mean ranks. Results 78 trials with 13 treatments were included. Overall, all GLP-1 RAs except for albiglutide increased the risk of hypoglycemia when compared to placebo. Reduction in the incidence of hypoglycemia was found for all GLP-1 RAs versus insulin (except for dulaglutide) and sulphonylureas. For the incidence of treatment discontinuation, increase was found for exenatide, liraglutide, lixisenatide and taspoglutide versus placebo, insulin and sitagliptin. For glycemic level, decrease was found for all GLP-1 RAs versus placebo. Dulaglutide, exenatide long-acting release (exe_lar), liraglutide and taspoglutide had significant lowering effect when compared with sitagliptin (HbA1c<7.0%) and insulin (HbA1c<6.5%). Finally, according to SUCRAs, placebo, thiazolidinediones and albiglutide had the best decrease effect on hypoglycemia; sulphanylureas, sitagliptin and insulin decrease the incidence of treatment discontinuation most; exe_lar and dulaglutide had the highest impact on glycemic level among 13 treatments. Conclusions Among 13 treatments, GLP-1 RAs had a significant reduction with glycemic level but a slight increase effect on hypoglycemia and treatment discontinuation. While albiglutide had the best decrease effect on hypoglycemia and treatment discontinuation among all GLP-1 RAs. However, further evidence is necessary for more conclusive inferences on mechanisms underlying the rise in hypoglycemia.

Abstract
AIMS To examine the efficacy and safety of once-weekly dulaglutide 0.75 mg monotherapy compared with once-daily liraglutide 0.9 mg in Japanese patients with type 2 diabetes (T2D) for 52 weeks. METHODS We conducted a phase III, randomized, 52-week (26-week primary endpoint), active- and placebo-controlled trial comparing 492 Japanese patients (dulaglutide, n = 281; liraglutide, n = 141; and placebo, n = 70). Participants and investigators were blinded to treatment assignment for dulaglutide and placebo but not for liraglutide (open-label comparator); after 26 weeks, patients randomized to placebo were switched to once-weekly dulaglutide 0.75 mg (open-label). The present paper reports results for patients treated with dulaglutide and patients treated with liraglutide for 52 weeks. RESULTS At week 52, dulaglutide decreased HbA1c significantly from baseline compared with liraglutide [least squares mean difference: -0.20; 95% confidence interval (CI) -0.39, -0.01; p = 0.04]. At week 52 (last observation carried forward), dulaglutide significantly decreased pre- and post-dinner blood glucose (BG) levels, the mean of seven-point self-monitored BG profiles, the mean of all postprandial BG levels and circadian variation compared with liraglutide. Body weight was generally stable in both groups through 52 weeks. The most frequently reported adverse events were nasopharyngitis, constipation, nausea and diarrhoea. Eight dulaglutide-treated (2.9%) and four liraglutide-treated (2.9%) patients reported hypoglycaemia, with no event being severe. CONCLUSIONS Monotherapy with once-weekly dulaglutide 0.75 mg was effective and safe in Japanese patients with T2D, with better glycaemic control compared with once-daily liraglutide 0.9 mg.

Abstract
INTRODUCTION Large randomized clinical trials have demonstrated that incretin-based therapies provide effective glycemic control in type 2 diabetes. Long-term safety assessments are ongoing. METHODS This systematic review of incretin-based therapy safety is based on 112 randomized clinical trials of duration ≥26 weeks published between January 2000 and February 2015 in patients with type 2 diabetes. RESULTS As expected, hypoglycemia rates were lower with dipeptidyl peptidase-4 inhibitors (DPP-4is) and glucagon-like peptide-1 receptor agonists (GLP-1 RAs) versus other oral antidiabetic drugs and insulin. The most common adverse events were infection and infestation (DPP-4is) and gastrointestinal (GLP-1 RAs). Pancreatitis cases were rare across all studies and, in the SAVOR-TIMI and EXAMINE trials, pancreatitis rates were similar in DPP-4i- and placebo-treated patients. No thyroid tumors were reported, and increased risk of cardiovascular events was not associated with DPP-4is in SAVOR-TIMI and EXAMINE, albeit over a short follow-up period. CONCLUSIONS Overall, incretin-based therapies were well tolerated; however, their long-term safety profile should continue to be periodically assessed.

Abstract
Over the last decade, the discovery of glucagon-like peptide 1 receptor agonists (GLP-1 RAs) has increased the treatment options for patients with type 2 diabetes mellitus (T2DM). GLP-1 RAs mimic the effects of native GLP-1, which increases insulin secretion, inhibits glucagon secretion, increases satiety and slows gastric emptying. This review evaluates the phase III trials for all approved GLP-1 RAs and reports that all GLP-1 RAs decrease HbA1c, fasting plasma glucose, and lead to a reduction in body weight in the majority of trials. The most common adverse events are nausea and other gastrointestinal discomfort, while hypoglycaemia is rarely reported when GLP-1 RAs not are combined with sulfonylurea or insulin. Treatment options in the near future will include co-formulations of basal insulin and a GLP-1 RA.

J Diabetes Complications 2015; 29:1203-10.

Abstract
AIMS The GLP-1 receptor agonist liraglutide improves impaired pancreatic β-cell function, thereby exerting glucose-lowering effects. However, the association of remaining β-cell function with long-term therapeutic efficacy of liraglutide remains largely unknown. METHODS Patients with type 2 diabetes who started liraglutide as monotherapy or sulfonylurea-combination therapy were retrospectively analyzed to identify possible associations of indices related to β-cell function including increments of C-peptide immunoreactivity in glucagon stimulation test (GST-ΔCPR) with achievement of HbA1c <7.0% at 54weeks after liraglutide initiation. RESULTS Among 165 subjects continuing liraglutide for 54weeks, 66 received additional oral anti-diabetic drugs (OADs) during the period. Of those continuing liraglutide without receiving additional OADs, 41 subjects achieved HbA1c <7.0% at 54weeks, while 49 subjects did not. Subjects achieving HbA1c <7.0% showed higher values of GST-ΔCPR. Receiver-operating analysis revealed 2.34ng/mL as the cut-off value for HbA1c <7.0% achievement in these subjects. Subjects with GST-ΔCPR >2.34ng/mL showed continuous and substantial HbA1c reduction throughout the 54weeks. In Kaplan-Meier analysis, subjects with GST-ΔCPR >2.34ng/mL showed longer therapeutic durability of initial liraglutide therapy with no additional OADs or insulin. CONCLUSIONS Despite numerous limitations, these results indicate that long-term efficacy of liraglutide is associated with remaining β-cell function at initiation.

Abstract
AIMS This 76-week, open-label, parallel-group study assessed the long-term safety of once-daily lixisenatide monotherapy in Japanese patients with type 2 diabetes mellitus. METHODS Patients were randomized to receive lixisenatide in a 2-step or a 1-step dose-increase regimen. The primary objective was to assess the safety of lixisenatide at week 24 by a descriptive comparison of the 2- and 1-step groups. RESULTS As expected with treatment with a glucagon-like peptide-1 agonist, nausea was the most common treatment-emergent adverse event (2-step group: n=12/33 [36.4%] vs 1-step group: n=18/36 [50.0%] up to week 24). In total, 5/33 patients (15.2%; 2-step group) and 2/36 patients (5.6%; 1-step group) prematurely discontinued treatment up to week 24, mainly due to adverse events. Serious treatment-emergent adverse events occurred in 2/33 patients (6.1%; 2-step group) versus 0/36 patients (0%; 1-step group) up to week 24. Symptomatic hypoglycemia occurred in 2/33 patients (6.1%; 2-step group) versus 1/36 patients (2.8%; 1-step group) up to week 24, with no severe events reported. Glycated hemoglobin, fasting plasma glucose, and body weight were reduced from baseline at weeks 24 and 76. CONCLUSION In Japanese patients with type 2 diabetes mellitus, once-daily lixisenatide monotherapy was well tolerated, with less nausea with the 2-step regimen.

Abstract
AIMS To evaluate 0.75 mg of dulaglutide, a once-weekly glucagon-like peptide-1 receptor agonist, compared with once-daily insulin glargine for glycaemic control in Japanese patients with type 2 diabetes (T2D). METHODS In this phase III, randomized, open-label, parallel-group, 26-week study, 361 patients with inadequately controlled T2D receiving sulphonylureas and/or biguanides, aged ≥20 years, with glycated haemoglobin (HbA1c) levels 7.0-10.0% (53-86 mmol/mol), inclusive, were randomized (1 : 1) to receive dulaglutide or glargine. Participants and investigators were not masked to treatment allocation. The primary measure was change from baseline in HbA1c at 26 weeks, analysed using a mixed-effects model for repeated measures, with a predefined non-inferiority margin of 0.4%. RESULTS At week 26, least-squares (LS) mean (standard error) reductions in HbA1c were -1.44 (0.05)% [-15.74 (0.55) mmol/mol] in the dulaglutide group and -0.90 (0.05)% [-9.84 (0.55) mmol/mol] in the glargine group. The mean between-group treatment difference in HbA1c was -0.54% (95% CI -0.67, -0.41) [-5.90 mmol/mol (95% CI -7.32, -4.48)]; p < 0.001. Dulaglutide significantly reduced body weight compared with glargine at week 26 (LS mean difference -1.42 kg, 95% CI -1.89, -0.94; p < 0.001). The most frequent adverse events with dulaglutide treatment were nasopharyngitis and gastrointestinal symptoms. The incidence of hypoglycaemia was significantly lower with dulaglutide [47/181 (26%)] compared with glargine [86/180 (48%)], p < 0.001. CONCLUSION In Japanese patients with T2D uncontrolled on sulphonylureas and/or biguanides, once-weekly dulaglutide was superior to once-daily glargine for reduction in HbA1c at 26 weeks. Although dulaglutide increased gastrointestinal symptoms, it was well tolerated, with an acceptable safety profile.

Abstract
Management of recent-onset diabetes offers osteopathic physicians the opportunity to work with patients to set treatment goals and expectations for this progressive yet manageable disease, as well as intervene early to reduce the risk of diabetes-related complications. Starting effective therapy early--and intensifying therapy appropriately--to achieve and maintain glycemic goals has been shown to reduce microvascular risks and produce legacy effects that may have macrovascular benefits. Metformin remains a cornerstone of therapy for those patients who can tolerate it. Early combination therapy that is well tolerated reduces risks of hypoglycemia or unwanted weight gain, improves patient adherence, and addresses the multifactoral pathophysiology of even recent-onset diabetes. Incretin-based therapies have been shown to be effective across the spectrum of type 2 diabetes mellitus, including recent-onset diabetes. The present article reviews the use of incretin-based therapies early in the disease process of type 2 diabetes mellitus.

Abstract
Subcutaneous liraglutide (Victoza(®)), a glucagon-like peptide 1 receptor agonist, is approved for the treatment of adult patients with type 2 diabetes mellitus. Once-daily liraglutide, as monotherapy or add-on therapy to other antidiabetic agents (including basal insulin), was an effective and generally well tolerated treatment in adult patients with type 2 diabetes in several well-designed phase III trials and in the real world clinical practice setting. In addition to improving glycaemic control, liraglutide had beneficial effects on bodyweight, systolic blood pressure and surrogate measures of β-cell function in clinical trials, with these benefits maintained during long-term treatment (≤2 years). Liraglutide has a convenient once-daily administration regimen, a low potential for drug-drug interactions and low propensity to cause hypoglycaemia. Thus, liraglutide continues to be a useful option for the management of type 2 diabetes. This article reviews the therapeutic use of liraglutide in adult patients with type 2 diabetes and summarizes its pharmacological properties.

Abstract
The Cochrane Metabolic and Endocrine Disorders Group withdrew this review as of Issue 7, 2015 because of the involvement of one author (SS Lund) being employed in a pharmaceutical company. The authors of the review and the Cochrane Metabolic and Endocrine Disorders Group did not find that this was a breach of the rules of the Cochrane Collaboration at the time when it was published. However, after the publication of the review, the Cochrane Collaboration requested withdrawal of the review due to the employment of the author. A new protocol for a review to cover this topic will be published. This will have a new title and a markedly improved protocol fulfilling new and important developments and standards within the Cochrane Collaboration as well as an improved inclusion and search strategy making it necessary to embark on a completely new review project. The editorial group responsible for this previously published document have withdrawn it from publication.

Abstract
Background Liraglutide was first released in Japan as a long-acting once-daily glucagon-like peptide-1 receptor agonist. The maximum dose in Japan is 0.9 mg/day, which is half of that used in the United States and the European Union (1.8 mg/day). The efficacy of this maximum allowable dose of liraglutide for Japanese patients and the profiles of those patients for whom this agent should be recommended remain unclear. Methods This study aimed to examine the effective use of liraglutide in Japanese type 2 diabetic patients. We administered liraglutide to 60 patients, who had been managed with oral hypoglycemic agents or diet and exercise therapy only, during a period of 6 months. Results Though HbA1c levels significantly decreased, by approximately 1.5%, after 6 months of liraglutide administration, no significant changes in body weights were observed. The 0.6 mg dose was effective in approximately 40% of patients. In contrast, the effects of a dose increase from 0.6 mg to 0.9 mg were small. The greatest efficacy, as shown by a 2.5% HbA1c decrease, was achieved in non-obese patients. Thus, efficacy decreased as the degree of obesity increased. In addition, efficacy was higher in patients who had a diabetes duration of less than 10 years and was also higher in the group that had a low sulfonylurea (SU) index, when we define the SU index as mg/glimepiride × years of treatment. Conclusions As appetite suppressions and associated decreases in body weights were not observed in obese patients, the efficacy of liraglutide at 0.9 mg did not appear to be high. Rather, it appeared to be highly effective for patients who were non-obese and for whom amelioration of blood glucose elevations could be anticipated via the stimulation of insulin secretion. Therefore, we found that liraglutide at doses of 0.9 mg was highly effective in non-obese patients who were in the early stages of diabetes and was particularly effective in patients who had not yet been administered SU agents.

Abstract
Introduction The safety and efficacy of liraglutide in combination with an oral antidiabetic drug (OAD) compared with combination of two OADs were assessed in Japanese patients with type 2 diabetes. Materials and Methods This was a 52‐week, open‐label, parallel‐group trial in which patients whose type 2 diabetes was inadequately controlled with a single OAD (glinide, metformin, α‐glucosidase inhibitor or thiazolidinedione) were randomized 2:1 to either pretrial OAD in combination with liraglutide 0.9 mg/day (liraglutide group; n = 240) or pretrial OAD in combination with an additional OAD (additional OAD group; n = 120). The primary outcome measure was the incidence of adverse events (AEs). Results Overall, 86.3% of patients in the liraglutide group and 85.0% of patients in the additional OAD group experienced AEs; these were similar in nature and severity. Adverse event rates were 361 and 331 per 100 patient‐years of exposure, respectively. Confirmed hypoglycemia was rare (seven episodes in two patients on liraglutide, and two in two patients on additional OAD). There were no reported pancreatitis events, and no unexpected safety signals were identified. Mean reductions in glycosylated hemoglobin were significantly greater in the liraglutide group than the additional OAD group [estimated mean treatment difference −0.27% (95% confidence interval (CI) −0.44, −0.09; P = 0.0026)]; reductions in mean fasting plasma glucose levels were also greater with liraglutide [estimated mean difference −5.47 mg/dL (−0.30 mmol/L; 95% CI: −10.83, −0.10; P = 0.0458)]. Conclusions Liraglutide was well tolerated and effective as combination therapy with an OAD in Japanese patients with type 2 diabetes.

Abstract
This study assessed the effect of GLP-1 based therapies on atherosclerotic markers in type 2 diabetes patients. 31 studies were selected to obtain data after multiple database searches and following inclusion and exclusion criteria. Age and BMI of the participants of longitudinal studies were 59.8 ± 8.3 years and 29.2 ± 5.7 kg/m2 (Mean±SD). Average duration of GLP-1 based therapies was 20.5 weeks. Percent flow-mediated diameter (%FMD) did not change from baseline significantly but when compared to controls, %FMD increased non-significantly following GLP-1-based therapies (1.65 [−0.89, 4.18]; P = 0.2; REM) in longitudinal studies and increased significantly in cross sectional studies (2.58 [1.68, 3.53]; P < 0.00001). Intima media thickness decreased statistically non-significantly by the GLP-1 based therapies. GLP-1 based therapies led to statistically significant reductions in the serum levels of brain natriuretic peptide (−40.16 [−51.50, −28.81]; P < 0.0001; REM), high sensitivity c-reactive protein (−0.27 [−0.48, −0.07]; P = 0.009), plasminogen activator inhibitor-1 (−12.90 [−25.98, 0.18]; P=0.05), total cholesterol (−5.47 [−9.55, −1.39]; P = 0.009), LDL-cholesterol (−3.70 [−7.39, −0.00]; P = 0.05) and triglycerides (−16.44 [−25.64, −7.23]; P = 0.0005) when mean differences with 95% CI in the changes from baselines were meta-analyzed. In conclusion, GLP-1-based therapies appear to provide beneficial effects against atherosclerosis. More randomized data will be required to arrive at conclusive evidence.

Abstract
Background The pathophysiology of type2 diabetes differs between different ethnic groups. Asians develop type2 diabetes at younger age, lower body mass index, and in relatively short time. Not only that, some ethnicities have different responses and dosing regimens to different classes of anti-diabetic agents. Data from Japanese population showed that the optimal doses of liraglutide used are smaller than other population and that weight loss is not as effective as seen in Caucasians. Methods We aimed to assess liraglutide efficacy in reducing weight and HbA1c in Arab population when used as add on to other anti-diabetic agents. We prospectively followed patients who were recruited to treatment with liraglutide for a 6 months period; at the start of the study we checked patients’ demographics, weight, blood pressure, fasting blood glucose, HbA1c, lipid panel, LFTs and creatinine. Patients were checked at 3 months and at the end of the study at 6 months. Results There was a significant reduction in weight at 3 and 6 months from a mean weight of 96.01 ± 19.2 kg to (94.8 ± 20 kg with (P < 0.001)) and 94.5 ± 19 kg with (p < 0.001) respectively. Mean HbA1c at baseline was 8.3 ± 1.7 % dropped to 7.7 ± 1.4 % (p < 0.001) at 3 months, and 7.6 + 1.6 % (p < 0.001) at 6 months. Conclusions Liraglutide is effective in reducing weight, HbA1c as well as other metabolic parameters in Arab population with type2 diabetes. Trial registration The trial is approved and registered with the Institutional Ethical Committee Board (Dubai Health Authority Medical Research Committee) under registration Number (MRC-08/2013_03).

Abstract
BACKGROUND This work aimed to compare the efficacy of dipeptidyl peptidase-IV (DPP-4) inhibitors and their impact on β-cell function in Asian and Caucasian patients with type 2 diabetes mellitus. METHODS Databases were systematically searched and qualifying studies that compared DPP-4 inhibitors with other antidiabetic medications in type 2 diabetes were included. RESULTS A total of 68 studies were included in the meta-analysis. Comparison of DPP-4 inhibitors with placebo in Asian patients showed a decrease in glycosylated hemoglobin (HbA1c ) favoring DPP-4 inhibitors (weighted mean difference [WMD], -0.81%; 95% confidence interval [CI], -0.95% to -0.68%; P < 0.001). Comparison of HbA1c changes between Asian and Caucasian patients showed a significant between-group difference of -0.18% (95% CI, -0.32% to -0.04%; P = 0.011) when compared with placebo. In Asian patients, the homeostatic model assessment for β-cell function (HOMA-β) was increased with DPP-4 inhibitors compared with placebo (WMD, 7.90; 95% CI, 4.29 to 11.51; P < 0.001), although to a lesser extent in Caucasian patients. Comparisons between Asian and Caucasian patients showed a significant between-group difference of -4.97 (95% CI, -9.86 to -0.09; P = 0.046) compared with placebo. Body weight increase with DPP-4 inhibitors compared with placebo was comparable in Asian and Caucasian studies (WMD, 0.37 kg and 0.45 kg and 95% CI, 0.04-0.69 and 0.27-0.62, respectively). CONCLUSIONS The glucose-lowering efficacy of DPP-4 inhibitors was greater in Asian patients than in Caucasian patients, although the effect on β-cell function was inferior in Asian patients. The effect of DPP-4 inhibitors on insulin resistance and body weight in Asian patients was comparable with that observed in Caucasian patients.

Abstract
GPR40 is a G protein-coupled receptor that is predominantly expressed in pancreatic β-cells. GPR40 agonists stimulate insulin secretion in the presence of high glucose concentration. On the basis of this mechanism, GPR40 agonists are possible novel insulin secretagogues with reduced or no risk of hypoglycemia. The improvement of in vitro activity and metabolic stability of compound 1 led to the discovery of 13, (3S)-3-ethoxy-3-(4-{[(1R)-4-(trifluoromethyl)-2,3-dihydro-1H-inden-1-yl]oxy}phenyl)propanoic acid, as a potent and orally available GPR40 agonist. Compound 13 (DS-1558) was found to have potent glucose lowering effects during an oral glucose tolerance test in ZDF rats.

Abstract
Impaired glucose-stimulated insulin secretion (GSIS) and increasing β-cell death are two typical dysfunctions of pancreatic β-cells in individuals that are destined to develop type 2 diabetes, and improvement of β-cell function through GSIS enhancement and/or inhibition of β-cell death is a promising strategy for anti-diabetic therapy. In this study, we discovered that the small molecule, N-(2-benzoylphenyl)-5-bromo-2-thiophenecarboxamide (BBT), was effective in both potentiating GSIS and protecting β-cells from cytokine- or streptozotocin (STZ)-induced cell death. Results of further studies revealed that cAMP/PKA and long-lasting (L-type) voltage-dependent Ca(2) (+) channel/CaMK2 pathways were involved in the action of BBT against GSIS, and that the cAMP/PKA pathway was essential for the protective action of BBT on β-cells. An assay using the model of type 2 diabetic mice induced by high-fat diet combined with STZ (STZ/HFD) demonstrated that BBT administration efficiently restored β-cell functions as indicated by the increased plasma insulin level and decrease in the β-cell loss induced by STZ/HFD. Moreover, the results indicated that BBT treatment decreased fasting blood glucose and HbA1c and improved oral glucose tolerance further highlighting the potential of BBT in anti-hyperglycemia research.

Abstract
The goal of this study was to assess the safety and efficacy of 0.75 mg of dulaglutide, a once weekly glucagon-like peptide-1 receptor agonist, in Japanese patients with type 2 diabetes (T2D) on a single oral hypoglycemic agent (OHA). In this phase 3, nonrandomized, open-label, parallel-group, 52-week study, safety and efficacy of once weekly dulaglutide 0.75 mg were assessed in Japanese patients with T2D on a single OHA (sulfonylureas [SU], biguanides [BG], α-glucosidase inhibitors [AGI], thiazolidinedione [TZD], or glinides [GLN]). A total of 394 patients were treated with study drug, and 92.9% completed the 52-week treatment period. The most frequent treatment-emergent adverse events were nasopharyngitis and gastrointestinal disorders, including constipation, diarrhea, and nausea. Incidences of hypoglycemia varied across the combination therapy groups: incidence was greater in patients receiving SU compared with other combinations. No severe hypoglycemic episodes occurred during the study. Increases from baseline in pancreatic and total amylase, lipase, and pulse rate were observed in all 5 combination therapy groups. Significant reductions from baseline in HbA1c were observed in all 5 combination therapy groups (-1.57% to -1.69%, p < 0.001 for all). Mean body weight changes from baseline varied across the combination therapy groups: a significant increase was observed in combination with TZD, there were no significant changes in combination with SU or GLN, and significant reductions were observed in combination with BG or AGI. Once weekly dulaglutide 0.75 mg in combination with a single OHA was overall well tolerated and improved glycemic control in Japanese patients with T2D.

Abstract
AIM In Japan, liraglutide is approved for use alone or in combination with sulfonylureas, and the approved maximum dosage is 0.9 mg/day. This restriction could limit the glucose-lowering effect of liraglutide in Japanese patients with type 2 diabetes mellitus (T2DM). This study was designed to identify predictors of response to liraglutide therapy at the approved dosage. METHODS This observational retrospective study included 380 patients with T2DM who were treated with liraglutide alone or in combination with sulfonylureas at Diabetes Centers located in four geographically different areas of Japan. Binary logistic regression analysis was used to identify patient characteristics associated with discontinuation of liraglutide, while multiple regression and decision tree analyses were used to identify predictors of response to liraglutide therapy. RESULTS Factors associated with discontinuation of liraglutide included high BMI, long duration of diabetes, and prior insulin therapy. Predictors of response to liraglutide therapy in patients who did not use insulin previously included previous use of few oral glucose-lowering agents and high baseline HbA1c level. CONCLUSION The results suggest greater efficacy of liraglutide monotherapy or liraglutide-sulfonylurea combination therapy in patients with short duration of diabetes, non-insulin therapy, and low BMI and high HbA1c level at baseline.

Abstract
Glucagon-like peptide1 (GLP-1) is secreted from Langerhans cells in response to oral nutrient intake. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are a new class of incretin-based anti-diabetic drugs. They function to stimulate insulin secretion while suppressing glucagon secretion. GLP-1-based therapies are now well established in the management of type 2 diabetes mellitus (T2DM), and recent literature has suggested potential applications of these drugs in the treatment of obesity and for protection against cardiovascular and neurological diseases. As we know, along with change in lifestyles, the prevalence of non-alcoholic fatty liver disease (NAFLD) in China is rising more than that of viral hepatitis and alcoholic fatty liver disease, and NAFLD has become the most common chronic liver disease in recent years. Recent studies further suggest that GLP-1RAs can reduce transaminase levels to improve NAFLD by improving blood lipid levels, cutting down the fat content to promote fat redistribution, directly decreasing fatty degeneration of the liver, reducing the degree of liver fibrosis and improving inflammation. This review shows the NAFLD-associated effects of GLP-1RAs in animal models and in patients with T2DM or obesity who are participants in clinical trials.

JAPANESE CLINICAL MEDICINE 2014; 5:33-41.

Abstract
OBJECTIVE Liraglutide (glucagon-like peptide-1 [GLP-1] receptor agonist) and sitagliptin (dipeptidyl peptidase-4 inhibitor) are approved in Japan for treating type 2 diabetes mellitus (T2DM). We compared the efficacy and safety of adding liraglutide or sitagliptin to a sulfonylurea in Japanese T2DM patients. METHODS Patients aged 18 to <80 years with hemoglobin A1c (HbA1c; National Glycohemoglobin Standardization Program [NGSP]) of 6.9–9.4%, body mass index ≤35 kg/m2, and treatment with a sulfonylurea and/or one or two non-sulfonylurea oral antidiabetic drugs for greater than or equal to eight weeks before enrollment were eligible. Patients were randomized in an open-label manner to either 0.9 mg/day liraglutide (n = 50) or 50–100 mg/day sitagliptin (n = 49) and were treated for 24 weeks. Non-sulfonylureas were discontinued before randomization. Patients using other oral antidiabetic drugs started sulfonylurea treatment. The primary endpoint was the change in HbA1c from baseline to Week 24. RESULTS HbA1c decreased in both groups, and the reduction was significantly greater throughout in the liraglutide group except for Week 24 (0.59 ± 0.80 vs. 0.24 ± 0.94%; P = 0.0525). Fasting plasma glucose (FPG) decreased significantly in the liraglutide group compared with the sitagliptin group (−21.15 ± 31.22 vs. +0.46 ± 39.39 mg/dL; P = 0.0014). Homeostasis model assessment of β cell function and C-peptide increased significantly in the liraglutide group but not in the sitagliptin group. Hypoglycemic symptoms and adverse events occurred in four and nine patients, respectively, in the liraglutide group, and in two and five patients, respectively, in the sitagliptin group. CONCLUSION Treatment with liraglutide or sitagliptin together with a sulfonylurea improved HbA1c in Japanese T2DM patients in primary care. Both drugs were associated with low rates of adverse events and hypoglycemia. The improvement in β cell function probably contributed to the improvement in glycemic control in the liraglutide group.

Abstract
When evaluating new drugs or treatments eligible for reimbursement, health technology assessment (HTA) agencies are repeatedly faced with cost-effectiveness analyses that evidence lack of adequate data and modeling biases. The case of type 2 diabetes illustrates this difficulty. In spite of its high disease burden, type 2 diabetes is poorly documented through existing cost-effectiveness analyses. We support this statement by an exhaustive literature review that enables us to precisely pinpoint the limitations of models used for the assessment of newly marketed (and expensive) drugs. We find that models are mostly restricted to surrogate endpoints and based on non-inferiority clinical trial data; they also show biases in the choice of comparators and inclusion criteria. Such limitations undermine the scope and applicability of HTA practice guidelines based on cost-effectiveness evidence. Nevertheless, cost-effectiveness models remain an opportunity to better inform decision makers and to reduce the uncertainty surrounding their decisions. HTA agencies are best placed to provide incentives for companies to improve the quality of the cost-effectiveness studies submitted for pricing and reimbursement decisions. One such incentive is to include stages of discussion between the company and the health authority during the evaluation process.
