Graefes Arch Clin Exp Ophthalmol 2024; 262:717-752. [PMID: 37728754 DOI: 10.1007/s00417-023-06236-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 08/30/2023] [Accepted: 09/07/2023] [Indexed: 09/21/2023] Open
Abstract
Diabetic retinopathy (DR) is the leading etiology of blindness in the working population of the USA. Its long-term management relies on effective glycemic control. Seven anti-diabetic classes have been introduced for patients with type 2 diabetes (T2D) in the past two decades, with different glucose-lowering and cardiovascular benefits. Yet, their effects specifically on DR have not been studied in detail. A systematic review of the literature was conducted to investigate this topic, focusing on the available clinical data for T2D. Published studies were evaluated based on their level of statistical evidence, as long as they incorporated at least one endpoint or adverse event pertaining to retinal health. Fifty nine articles met our inclusion criteria and were grouped per anti-diabetic class as follows: alpha-glucosidase inhibitors (1), peroxisome proliferator-activated receptor gamma (PPAR-γ) agonists (8), amylin analogs (1), glucagon-like peptide-1 (GLP-1) receptor agonists (28), dipeptidyl peptidase 4 (DPP-4) inhibitors (9), and sodium glucose co-transporter-2 (SGLT-2) inhibitors (9), plus one retrospective study and two meta-analyses evaluating more than one of the aforementioned anti-diabetic categories. We also reviewed publicly-announced results of trials for the recently-introduced class of twincretins. The available data indicates that most drugs in the newer anti-diabetic classes are neutral to DR progression; however, there are subclasses differences in specific drugs and T2D populations. In particular, there is evidence suggesting there may be worse diabetic macular edema with PPAR-gamma agonists, potential slight DR worsening with semaglutide (GLP-1 receptor agonist), and potential slight increase in the incidence of retinal vein occlusion in elderly and patients with advanced kidney disease receiving SGLT-2 inhibitors. All these warrant further investigation. Longer follow-up and systematic assessment of at least one DR-related endpoint are highly recommended for all future trials in the T2D field, to ultimately address this topic.

Effect of tirzepatide on glycaemic control and weight loss compared with other glucagon-like peptide-1 receptor agonists in Japanese patients with type 2 diabetes mellitus. Diabetes Obes Metab 2024; 26:262-274. [PMID: 37828829 DOI: 10.1111/dom.15312] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Revised: 09/10/2023] [Accepted: 09/19/2023] [Indexed: 10/14/2023]
Abstract
AIM To compare the therapeutic effects of glucose-dependent insulinotropic polypeptide (GIP)/ glucagon-like peptide-1 receptor agonists (GLP-1RAs) or GLP-1RAs in Japanese patients with type 2 diabetes (T2D). MATERIALS AND METHODS We systematically searched PubMed, MEDLINE, EMBASE, and the Cochrane Library up to July 2023. Randomized controlled trials (RCTs) that compared GLP-1RAs or GIP/GLP-1RAs in Japanese patients with T2D were selected. A network meta-analysis was conducted to indirectly compare the treatments, focusing on efficacy in reducing glycated haemoglobin (HbA1c) levels and body weight (BW). RESULTS A total of 18 RCTs were included in this analysis. Tirzepatide 15 mg showed the most significant reduction in HbA1c levels and BW compared with subcutaneous semaglutide 1.0 mg and oral semaglutide 14 mg (HbA1c: mean difference [95% confidence interval] -0.52 [-0.96; -0.08] and - 1.23 [-1.64; -0.81]; BW: -5.07 [-8.28; -1.86] and -6.84 [-8.97; -4.71], respectively). Subcutaneous semaglutide showed a superior reduction in HbA1c compared with oral semaglutide. Both subcutaneous and oral semaglutide were more effective than conventional GLP-1RAs, such as dulaglutide, liraglutide and lixisenatide. CONCLUSIONS Among Japanese patients with T2D, tirzepatide showed the greatest effectiveness in reducing HbA1c levels and inducing weight loss. The study provides evidence to guide GLP-1RA treatment strategies in Japanese patients with T2D.

Abstract
BACKGROUND Glucagon-like peptide 1 receptor agonists (GLP-1RAs) exhibit glucose-lowering, weight-reducing, and blood pressure-lowering effects. Nevertheless, a debate exists concerning the association between GLP-1RA treatment and the risk of diabetic retinopathy (DR) in patients diagnosed with type 2 diabetes mellitus (T2DM). OBJECTIVE To ascertain the risk of DR in patients with T2DM undergoing GLP-1RA treatment, we conducted a meta-analysis utilizing data derived from randomized placebo-controlled studies (RCTs). METHODS A comprehensive literature search was conducted using PubMed, Cochrane Library, Web of Science, and EMBASE. We focused on RCTs involving the use of GLP-1RAs in patients with T2DM. Utilizing R software, we compared the risk of DR among T2DM patients undergoing GLP-1RA treatment. The Cochrane risk of bias method was employed to assess the research quality. RESULTS The meta-analysis incorporated data from 20 RCTs, encompassing a total of 24,832 T2DM patients. Across all included trials, randomization to GLP-1 RA treatment did not demonstrate an increased risk of DR (odds ratio = 1.17; 95% CI 0.98-1.39). Furthermore, no significant heterogeneity or publication bias was detected in the analysis. CONCLUSION The results of this systematic review and meta-analysis indicate that the administration of GLP-1 RA is not associated with an increased risk of DR.

Abstract
Background Clinical use of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) is well established as add-on therapy to oral medications and basal insulin. However, there is little published data regarding the use of GLP-1 RAs for longer than 12 months in patients taking basal/bolus insulin regimens. The primary goal of our study was to assess the long-term efficacy of GLP-1 RAs as add-on therapy to basal/bolus insulin regimens. Methods This study was a retrospective record review of all patients on basal/bolus insulin regimens who received additional therapy with a GLP-1 RA. The primary outcome was the change in glycosylated hemoglobin A1c (HbA1c) at 3, 6, 12, 18, and 24 months after initiation of the GLP-1 RA. Secondary outcomes included change in weight and total daily dose (TDD) of insulin and incidence of hypoglycemia and other adverse effects (AEs). Results Ninety-two patient records were reviewed. Mean glycemic control changed from baseline -1.1% (95% CI, -1.3 to -0.8; P < .001) at 3 months; -1.0% (95% CI, -1.3 to -0.7; P < .001) at 6 months; -0.9% (95% CI, 1.3 to -0.6; P < .001) at 12 months; -0.9% (95% CI, -1.4 to -0.3; P = .002) at 18 months; and -0.7 (95% CI, -1.4 to 0.1; P = .07) at 24 months. A significant decrease in weight was also observed from baseline through 18 months, and a significant decrease in TDD of insulin was identified from baseline through 12 months. Hypoglycemia was documented in 29.8% of patients at any point during GLP-1 RA therapy, and gastrointestinal AEs were documented in 18.3% of patients. Conclusions Adding GLP-1 RAs to complex insulin regimens may help achieve glycemic control while decreasing insulin requirements and mitigating undesirable AEs, such as weight gain.

Abstract
AIMS The effect of Glucagon-like peptide 1 receptor agonists (GLP1 RA) on diabetic retinopathy (DR) remains controversial. Previous reviews combined data from randomized clinical trials (RCTs) with or without cardiovascular (CV) benefits and did not address confounders, therefore may have generated misleading results. The study aimed to examine the effect of GLP1RA on DR in type 2 diabetes (T2DM) in RCTs with or without CV benefits and distinguish the effect by major confounders. METHODS We conducted electronic searches of multiple databases and a manual search using references lists. We included 13 RCTs examining the effect of GLP1 RA on health outcomes/adverse events including DR or DR complications in T2DM. We performed a random-effects model meta-analysis. RESULTS GLP1RA was associated with an elevated risk of rapidly worsening DR in four major RCTs with CV benefits in T2DM (OR 1.23, 95 % CI 1.05-1.44). The association between GLP1 RA and DR was significant in subgroups of RCTs with length over 52 weeks (1.2, 1.00-1.43), using placebo as a comparator (1.22, 1.05-1.42). In subgroups with patients who had T2DM ≥10 years (1.19, 0.99-1.42) or with subjects enrolled from multiple countries (1.2, 0.99-1.46), the association appeared to be evident but did not reach statistical significance. CONCLUSIONS GLP1 RA including liraglutide, semaglutide, and dulaglutide are associated with an increased risk of rapidly worsening DR in RCTs with CV benefits. Further data from clinical studies with longer follow-up purposefully designed for DR risk assessment, particularly including patients of established DR are warranted.

Abstract
BACKGROUND AND AIMS Clinical trials indicate the efficacy of add-on therapy using incretin-related drugs to treat type 2 diabetes mellitus (DM) inadequately controlled by insulin. However, heterogeneity exists among these studies. Baseline body mass index (BMI) accounts for the heterogeneity of add-on therapy with dipeptidyl peptidase-4 (DPP-4) inhibitors and the associated higher BMI with a lower efficacy. The efficacy of add-on therapy with glucagon-like peptide-1 (GLP-1) receptor agonists remains unclear. METHODS We performed a meta-analysis of randomized controlled trials of ≥12 weeks reporting the endpoint of adjusted mean change in hemoglobin A1c levels (AMΔHbA1c) or hypoglycemia incidence. Patients with type 2 DM treated with insulin alone or with metformin for at least 8 weeks before the study treatment were included. The intervention group received liraglutide co-administered with insulin or a fixed-dose combination. The control group received a placebo or insulin. Covariates included five baseline parameters (HbA1c, fasting plasma glucose, BMI, type 2 DM duration, and treatment duration). RESULTS Seven studies (2067 patients) were selected. AMΔHbA1c was -1.00% (95% confidence interval [CI]: -1.21 to -0.78, I2 = 74.7%). The odds ratio for hypoglycemia incidence was 0.97 (95% CI: 0.50-1.87, I2 = 81.9%). Covariates did not account for the heterogeneity in AMΔHbA1c or hypoglycemia incidence. CONCLUSIONS Liraglutide add-on therapy reduced HbA1c levels without increasing hypoglycemia incidence, independent of BMI, in insulin non-responders with type 2 DM. GLP-1 receptor agonists may be more suitable than DPP-4 inhibitors for add-on therapy in patients with high BMI. REGISTRATION NUMBER PROSPERO #CRD42021178888.

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
INTRODUCTION The relative efficacy and safety of once-daily oral semaglutide vs. injectable glucagon-like peptide-1 receptor agonists (GLP-1 RAs) in subjects with type 2 diabetes (T2D) inadequately controlled on basal insulin were assessed using network meta-analysis (NMA). METHODS A systematic literature review (SLR) was performed to identify randomised controlled trials of GLP-1 RAs in this population. Data at 26 ± 4 weeks were extracted for efficacy and safety outcomes feasible for the NMA: change from baseline in glycated haemoglobin (HbA1c), weight and blood pressure; HbA1c target levels (< 7.0% and ≤ 6.5%); composite endpoint; incidence of nausea, vomiting or diarrhoea. Comparators of interest were all licensed doses of dulaglutide, exenatide, liraglutide, lixisenatide and once-weekly injectable semaglutide. RESULTS The NMA included seven trials. Once-daily oral semaglutide 14 mg was associated with significantly greater HbA1c reductions vs. most comparators (treatment differences: - 0.42 to - 1.32%); differences vs. once-weekly injectable semaglutide (0.5 mg and 1 mg doses) were not statistically significant. Once-daily oral semaglutide 14 mg was associated with significantly greater weight reductions vs. exenatide 2 mg and lixisenatide 20 μg (- 2.21 and - 2.39 kg respectively); non-statistically significant weight reductions in favour of once-daily oral semaglutide 14 mg were observed vs. all other comparators except once-weekly injectable semaglutide 1 mg. Similar trends were observed for the proportion of subjects achieving HbA1c < 7.0% and ≤ 6.5% and the composite endpoint. Once-daily oral semaglutide 14 mg was associated with similar odds of experiencing nausea, vomiting or diarrhoea vs. all comparators. CONCLUSION Once-daily oral semaglutide 14 mg, as an add-on to basal insulin, is an efficacious treatment for reducing HbA1c and weight and meeting glycaemic targets at 26 ± 4 weeks. Once-daily oral semaglutide 14 mg also offers the option of an oral treatment with similar or better efficacy and similar tolerability vs. most injectable GLP-1 RAs.

Abstract
OBJECTIVE To assess the available literature evaluating the efficacy and safety of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) with multiple daily insulin injections (MDII). DATA SOURCES A literature search of MEDLINE and Embase was performed (2004 to May 2020) using the following search terms: glucagon-like 1 receptor agonist, liraglutide, albiglutide, dulaglutide, exenatide, semaglutide, diabetes mellitus, and prandial insulin or bolus insulin. Additional references were obtained from cross-referencing the bibliographies of selected articles. STUDY SELECTION AND DATA EXTRACTION All information obtained from the searches were reviewed. All relevant trials are included in this review. DATA SYNTHESIS Eight studies met criteria for inclusion. The addition of a GLP-1 RA to multiple daily insulin injections was associated with a reduction in A1c in 7 out of 8 studies, and weight loss in 5 studies. In studies that allowed insulin adjustment after the addition of GLP-1 RA, the average total daily insulin dose was reduced in 3 studies. When evaluated, hypoglycemia frequency or other adverse events were not increased when GLP-1 RAs were added to MDII. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE Guidelines do not offer recommendations regarding the use of GLP-1 RAs in combination with MDII regimens. This review evaluates current studies demonstrating efficacy and safety considerations of this combination. CONCLUSIONS While some studies did demonstrate an improvement in A1c and reduction in insulin doses without increased hypoglycemia, larger randomized controlled trials are needed to adequately assess the benefit and safety of GLP-1 RAs in combination with MDII.

Abstract
AIM We compared the efficacy and safety of insulin degludec/insulin aspart co-formulation (IDegAsp) twice-daily to a free combination of basal insulin degludec and GLP-1 receptor agonist liraglutide (IDeg + Lira) once-daily for patients with inadequately controlled type 2 diabetes on insulin therapy and oral antidiabetic drugs. SUBJECTS AND METHODS Eligible patients were randomly allocated at a 1:1 ratio to receive either the once-daily dual injection of IDeg + Lira (n = 24) or twice-daily single injection of IDegAsp (n = 28). The primary endpoints were as follows: HbA1c changes over 52 weeks of treatment and the percentage of participants achieving HbA1c < 7.0% at week 52. RESULTS After 52 weeks, HbA1c decreased by 0.3% in the IDegAsp group and by 0.7% in the IDeg + Lira group. The HbA1c reduction was greater in the IDeg + Lira group than in the IDegAsp group. 19% of patients on IDegAsp versus 40% on IDeg + Lira achieved HbA1c < 7.0%. Pre-breakfast and pre-dinner blood glucose at 52 weeks were significantly lower in the IDeg + Lira group than in the IDegAsp group. The reduction in body mass index (BMI) was greater in the IDeg + Lira group than in the IDegAsp group throughout the study period. The confirmed hypoglycaemia rates were 1.32 and 0.69 per patient/year of exposure to IDegAsp and IDeg + Lira, respectively. CONCLUSIONS In patients with inadequately controlled type 2 diabetes on insulin therapy and oral antidiabetic drugs, treatment with the once-daily dual injection of IDeg + Lira compared with the twice-daily single injection of IDegAsp showed no significant difference in glycaemic control but statistically superior weight loss.

Preference for Oral and Injectable GLP-1 RA Therapy Profiles in Japanese Patients with Type 2 Diabetes: A Discrete Choice Experiment. Adv Ther 2021; 38:721-738. [PMID: 33245530 PMCID: PMC7854394 DOI: 10.1007/s12325-020-01561-1] [Citation(s) in RCA: 22] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/14/2020] [Accepted: 11/04/2020] [Indexed: 02/06/2023]
Abstract
INTRODUCTION Glucagon-like peptide 1 (GLP-1) receptor agonists (RAs) approved to date are administered by injection; therefore, patient perceptions of an oral GLP-1 RA are unknown. This discrete choice experiment explored preferences for (unbranded) oral and injectable GLP-1 RA profiles among Japanese patients with type 2 diabetes (T2D). METHODS An online survey was designed using literature review and qualitative interview findings, and administered to Japanese patients with T2D and HbA1c ≥ 7.0% receiving oral antiglycaemic medication (with no experience of injectable antiglycaemic medication). Therapy profiles were created using Japanese head-to-head trial data for orally administered semaglutide (7 mg and 14 mg), injectable dulaglutide (0.75 mg), and injectable liraglutide (0.9 mg). Profiles were not labelled. Choice tasks tested preference between hypothetical profiles, preference between profiles with actual trial data, and willingness to initiate treatment. Relative importance of attributes was determined using conditional logit regression. RESULTS A total of 500 respondents were analysed: mean age 61.2 years; 93.8% male; mean HbA1c 7.6%; 78.2% with HbA1c ≥ 7.0 to < 8%; 89% with HbA1c above personal target. Mean BMI was 25.4 kg/m2; 49% had obesity (≥ 25 kg/m2). The treatment attribute with greatest importance was mode and frequency of administration (49.1%), followed by nausea risk (30.8%), weight change (11.3%), and HbA1c change (8.8%). Oral semaglutide 7 and 14 mg-like profiles were both preferred: the 7 mg-like profile was preferred over dulaglutide (by 91.0% of respondents) and liraglutide (by 89.4%); the 14 mg-like profile was preferred over dulaglutide (by 88.2%) and liraglutide (by 94.4%). Willingness to initiate treatment was also higher for orally administered semaglutide-like profiles: 62.4% with 7 mg and 64.0% with 14 mg, versus 13.6% and 11.0% with injectable GLP-1 RA-like profiles. Subgroup results were generally consistent with the overall sample. CONCLUSION Japanese patients with T2D appear to prefer oral GLP-1 RA profiles over injectable GLP-1 RA profiles, and administration appears to be the most important factor in this decision. This highlights the unmet need for an effective and orally administered GLP-1 RA for the treatment of T2D in Japan.

Abstract
OBJECTIVES To compare the therapeutic efficacy of liraglutide (LRG) single drug combined with insulin (Ins) on osteoporosis in rats and its effect on bone mineral density (BMD). A rat model of diabetes combined with osteoporosis was established. METHODS 40 Sprague-Dawley rats were divided into four groups (blank, control, LRG and LRG+Ins). Serum levels of CrossLaps, procollagen type I N propeptide (PINP), alkaline phosphatase (AKP) and osteocalcin (BGP) were detected by ELISA. Blood glucose was measured by its reaction with glucose oxidase. Serum insulin was analyzed by radioimmunology. Bone calcium and phosphorus contents were also recorded. ELISA was used to detect inflammatory factors. Bone mineral density (BMD) measurement was also performed. RESULTS BMD of the control group was significantly lower than that of the other three groups (p<0.05) and BMD of the LRG + Ins group was significantly higher than that of the LRG group (p<0.05). The inflammatory factors of the control group were significantly higher than those in the other three groups (p<0.05). The inflammatory factors were negatively correlated with BMD (p<0.05). CONCLUSIONS liraglutide in combination with insulin for the treatment of diabetes complicated with osteoporosis can reduce blood glucose in vivo, promote production of islet, effectively improve osteoporosis symptoms, increase BMD and reduce the levels of inflammatory factors in vivo.

[PMID: 33190640 PMCID: PMC7667845 DOI: 10.1186/s12916-020-01787-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2020] [Accepted: 09/17/2020] [Indexed: 01/10/2023] Open
Abstract
BACKGROUND The placebo response in patients with diabetes mellitus is very common. A systematic evaluation needs to be updated with the current evidence about the placebo response in diabetes mellitus and the associated factors in clinical trials of anti-diabetic medicine. METHODS Literature research was conducted in Medline, Embase, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov for studies published between the date of inception and June 2019. Randomized placebo-controlled trials conducted in type 1and type 2 diabetes mellitus (T1DM/T2DM) were included. Random-effects model and meta-regression analysis were accordingly used. This meta-analysis was registered in PROSPERO as CRD42014009373. RESULTS Significantly weight elevation (effect size (ES) = 0.33 kg, 95% CI, 0.03 to 0.61 kg) was observed in patients with placebo treatments in T1DM subgroup while significantly HbA1c reduction (ES = - 0.12%, 95% CI, - 0.16 to - 0.07%) and weight reduction (ES = - 0.40 kg, 95% CI, - 0.50 to - 0.29 kg) were observed in patients with placebo treatments in T2DM subgroup. Greater HbA1c reduction was observed in patients with injectable placebo treatments (ES = - 0.22%, 95% CI, - 0.32 to - 0.11%) versus oral types (ES = - 0.09%, 95% CI, - 0.14 to - 0.04%) in T2DM (P = 0.03). Older age (β = - 0.01, 95% CI, - 0.02 to - 0.01, P < 0.01) and longer diabetes duration (β = - 0.02, 95% CI, - 0.03 to - 0.21 × 10-2, P = 0.03) was significantly associated with more HbA1c reduction by placebo in T1DM. However, younger age (β = 0.02, 95% CI, 0.01 to 0.03, P = 0.01), lower male percentage (β = 0.01, 95% CI, 0.22 × 10-2, 0.01, P < 0.01), higher baseline BMI (β = - 0.02, 95% CI, - 0.04 to - 0.26 × 10-2, P = 0.02), and higher baseline HbA1c (β = - 0.09, 95% CI, - 0.16 to - 0.01, P = 0.02) were significantly associated with more HbA1c reduction by placebo in T2DM. Shorter diabetes duration (β = 0.06, 95% CI, 0.06 to 0.10, P < 0.01) was significantly associated with more weight reduction by placebo in T2DM. However, the associations between baseline BMI, baseline HbA1c, and placebo response were insignificant after the adjusted analyses. CONCLUSION The placebo response in diabetes mellitus was systematically outlined. Age, sex, disease severity (indirectly reflected by baseline BMI and baseline HbA1c), and disease duration were associated with placebo response in diabetes mellitus. The association between baseline BMI, baseline HbA1c, and placebo response may be the result of regression to the mean.

Abstract
AIMS/INTRODUCTION Obesity and metabolic syndrome are well-known to be associated with multiple chronic diseases. Currently, high-dose liraglutide has been used for weight control in non-diabetic patients. Considering incretin-based therapy is more effective in Asian populations, the effect of low-dose liraglutide in weight control among these non-diabetic groups has not been well evaluated. Our study aimed to evaluate the efficacy of low-dose liraglutide in weight control among Taiwan patients. MATERIALS AND METHODS From July 2017 to December 2018, 46 non-diabetic patients with metabolic syndrome were included. They had received low-dose liraglutide at 0.6 or 1.2 mg per day for weight reduction for 12 weeks. After then, changes in bodyweight, waist and metabolic factors were examined. Overt bodyweight reduction was defined as a decrease of >5% within 12 weeks. RESULTS With 12 weeks of medication use, both groups showed statistical weight reduction. Higher doses of liraglutide had better efficacy, and 44.4% of patients in the liraglutide 1.2 mg group reached overt weight reduction, whereas just 32.1% in the 0.6 mg group had achieved this. Young age was found to be a predictor factor for a positive finding (odds ratio 0.941, P = 0.037). Early responders with decreased bodyweight of >4.2% within the first 4 weeks indicated a better chance to achieve measurable weight reduction. CONCLUSIONS Low-dose liraglutide still has high efficacy in weight reduction in Taiwanese people, especially for those of younger age.

Abstract
Aims/Introduction Liraglutide and empagliflozin suppress cardiovascular events. However, reports on their long‐term combined use with insulin therapy or direct comparisons of these drugs are limited. Materials and Methods This open‐label, parallel‐group, randomized controlled trial compared the effects of liraglutide and empagliflozin combined with insulin therapy in type 2 diabetes patients. Adult type 2 diabetes outpatients undergoing stable insulin therapy with glycated hemoglobin levels of 7.0–9.5% were enrolled. Participants received 0.9 mg/day liraglutide or 10 mg/day empagliflozin for 24 weeks. The primary end‐point was the change in glycated hemoglobin levels from week 0 to 24. Body composition was assessed by dual‐energy X‐ray absorptiometry. Results A total of 64 insulin‐treated patients were randomized to receive liraglutide or empagliflozin. We analyzed 61 patients (30 liraglutide and 31 empagliflozin) who could be followed up. Liraglutide induced greater changes in glycated hemoglobin and glycated albumin than empagliflozin (glycated hemoglobin −1.24 ± 0.15% vs −0.35 ± 0.11%, P < 0.0001; glycated albumin −4.4 ± 0.6% vs −2.4 ± 0.5%, P < 0.01). Bodyweight (−1.3 ± 0.4 kg vs −1.5 ± 0.3 kg, P = 0.69) or body fat mass/lean tissue mass; urinary albumin excretion (median −5.3 mg/g‐creatinine [interquartile range −60.6, 9.9 mg/g‐creatinine] vs −12.9 mg/g‐creatinine [interquartile range −70.8, −2.0 mg/g‐creatinine], P = 0.23); and frequency of hypoglycemia did not differ significantly between the groups over a period of 24 weeks. There were no cases of study discontinuation owing to adverse effects. Conclusions Liraglutide addition to ongoing insulin therapy more effectively reduced glycated hemoglobin and glycated albumin levels than empagliflozin in patients with inadequately controlled type 2 diabetes.

Abstract
AIM Glucagon-like peptide-1 receptor agonist (GLP-1RA) and insulin combination therapy is an effective treatment option for type 2 diabetes, but long-term data are lacking. The aim was to assess the long-term efficacy of the GLP-1RA liraglutide in subgroups by insulin use in the LEADER trial. MATERIALS AND METHODS LEADER assessed cardiovascular (CV) safety and efficacy of liraglutide (1.8 mg) versus placebo (plus standard of care therapy) in 9340 patients with type 2 diabetes and high risk of CV disease, for up to 5 years. We analyzed CV events, metabolic parameters and hypoglycaemia post hoc in three subgroups by baseline insulin use (basal-only insulin, other insulin or no insulin). Insulin was a non-random treatment allocation as part of standard of care therapy. RESULTS At baseline, 5171 (55%) patients were not receiving insulin, 3159 (34%) were receiving basal-only insulin and 1010 (11%) other insulins. Insulin users had a longer diabetes duration and slightly worse glycaemic control (HbA1c) than the no-insulin subgroup. Liraglutide reduced HbA1c and weight versus placebo in all three subgroups (P < .001), and severe hypoglycaemia rate in the basal-only insulin subgroup. The need for insulin was less with liraglutide. CV risk reduction with liraglutide was similar to the main trial results in the basal-only and no-insulin subgroups. CONCLUSIONS In patients on insulin, liraglutide improved glycaemic control, weight and need for insulin versus placebo, for at least 36 months with no increased risk of severe hypoglycaemia, while maintaining CV safety/efficacy, supporting the combination of liraglutide and insulin for management of type 2 diabetes.

Abstract
We aimed to explore the use of the flash glucose monitoring (FGM) system in hospitalized newly diagnosed type 2 diabetes mellitus (T2DM) patients and to evaluate a new combination therapy of continuous subcutaneous insulin infusion (CSII) with or without liraglutide. This was an open-label, randomized study that was conducted in 60 newly diagnosed T2DM patients. The patients were randomized to receive either CSII (n = 30) or CSII + liraglutide (n = 30). The FGM system was used to assess the glycemic control and glycemic variability (GV) indices for 2 weeks. Mean blood glucose concentration (MBG), estimated hemoglobin A1c (HbA1c), and measures of GV, including the standard deviation of the mean glucose (SD), coefficient of variation (CV), interquartile range (IQR), mean amplitude of glycemic excursions (MAGE), largest amplitude of glycemic excursions (LAGE), and mean of daily difference (MODD) were compared between the two groups. Two oxidative stress biomarkers, 4-hydroxynonenal (4-HNE) and 8-hydroxydeoxyguanosine (8-OHdG), were measured before and after treatment. The estimated HbA1c and MBG decreased in both groups, especially the CSII + liraglutide group. SD, IQR, LAGE, and MODD were significantly lower in the CSII + liraglutide group than in the CSII group (all p < 0.05); there was no difference in CV or MAGE (p > 0.05). Similarly, the 4-HNE and 8-OHdG levels were significantly lower in the CSII + liraglutide group (p < 0.05). Our findings suggest that CSII with liraglutide was superior to CSII monotherapy in improving glycemic control and glycemic variability and in decreasing oxidative stress markers. Flash glucose monitoring can successfully provide ambulatory glucose profile data in the real world.

Abstract
We provided an updated systematic review with meta-analysis of randomized controlled trials (RCTs) assessing the metabolic effects of combination therapy of insulin and GLP-1RA (combo) in comparison with other injectable therapy. We searched PubMed, Cochrane Register of Controlled Trials, Scholar, and ClinicalTrials.gov for RCTs evaluating changes in HbA1c (primary outcome), proportion of patients at HbA1c target <7%, hypoglycaemia, and weight change (secondary end-points). We included 36 RCTs involving 14,636 patients. Compared with comparator therapies (overall analysis), the combo led to a significant HbA1c reduction (=-0.49%, 95% CI -0.61 to -0.38%, P < 0.001), more patients at HbA1c target [relative risk, (RR) = 1.77, 95% CI, 1.56, 2.01, P < 0.001], similar hypoglycaemic events (RR = 1.03, 95% CI, 0.88, 1.19, P = 0.728), and reduction in body weight (-2.5 Kg, 95% CI -3.1 to -1.8 kg, P < 0.001), with high heterogeneity in each analysis. The quality of the evidence was low for three of the considered outcomes. Compared with intensified insulin regimens (basal-plus/basal-bolus) the combo produced similar glycemic control with reduction of both hypoglycaemia, and body weight. Combination therapy of GLP-1RA and insulin could represent a valuable treatment strategy to improve glycemic control in the management of type 2 diabetes.

Abstract
Insulin glargine (IGlar) 100 U/mL (IGlar-100) is widely used in East Asian countries for the treatment of type 2 diabetes mellitus (T2DM) and is the gold standard of basal insulin treatment. In this review we summarize key information about clinical experience with IGlar-100 in East Asian patients with T2DM, including findings from clinical trials and postmarketing studies. We also provide recommendations and opinions on the optimal use of IGlar-100 in this population. The findings from the studies highlighted in our review indicate that IGlar-100 can be a suitable treatment option for East Asians with T2DM, from initial therapy in combination with oral antihyperglycemic medications through to different combinations and intensification models.

Abstract
AIMS/INTRODUCTION Research has proved a correlation between glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and gastrointestinal adverse events. Predominantly, nausea and vomiting are frequent gastrointestinal adverse events that lead to the discontinuation of GLP-1 RAs treatment. The present study aims to investigate clinical factors related to nausea and vomiting, considering diabetic complications and agents affecting the gastrointestinal tract, such as proton pump inhibitors (PPIs) and histamine-2 receptor antagonists (H2RAs), in patients with type 2 diabetes treated with GLP-1 RAs. MATERIALS AND METHODS This retrospective study included Japanese patients with type 2 diabetes who started receiving GLP-1 RAs therapy. We assessed nausea and vomiting up to 48 weeks after treatment with GLP-1 RAs and used Fine-Gray's proportional hazards model to investigate clinical factors related to nausea and vomiting. RESULTS A total of 130 patients were included in this study. Patients with PPIs or H2RAs showed a higher incidence of nausea and vomiting at 48 weeks than those without PPIs or H2RAs. The multivariate analysis revealed that female sex, retinopathy and treatment with PPIs or H2RAs were statistically significant risk factors for nausea and vomiting. Analysis of patients without PPIs or H2RAs showed that female sex and retinopathy were also statistically significant risk factors. CONCLUSIONS The present study showed a significant correlation of PPIs or H2RAs, female sex, and diabetic retinopathy with nausea and vomiting in patients with type 2 diabetes treated with GLP-1 RAs. Hence, the occurrence of nausea and vomiting in patients with these factors warrants attention.

Abstract
Glucagon-like peptide-1 (GLP-1) receptor agonists (RAs) are an important class of drugs with a well-established efficacy and safety profile in patients with type 2 diabetes mellitus. Agents in this class are derived from either exendin-4 (a compound present in Gila monster venom) or modifications of human GLP-1 active fragment. Differences among these drugs in duration of action (ie, short-acting vs long-acting), effects on glycaemic control and weight loss, immunogenicity, tolerability profiles, and administration routes offer physicians several options when selecting the most appropriate agent for individual patients. Patient preference is also an important consideration. The aim of this review is to discuss the differences between and similarities of GLP-1 RAs currently approved for clinical use, focusing particularly on the properties characterising the single short-acting and long-acting GLP-1 RAs rather than on their individual efficacy and safety profiles. The primary pharmacodynamic difference between short-acting (ie, exenatide twice daily and lixisenatide) and long-acting (ie, albiglutide, dulaglutide, exenatide once weekly, liraglutide, and semaglutide) GLP-1 RAs is that short-acting agents primarily delay gastric emptying (lowering postprandial glucose) and long-acting agents affect both fasting glucose (via enhanced glucose-dependent insulin secretion and reduced glucagon secretion in the fasting state) and postprandial glucose (via enhanced postprandial insulin secretion and inhibition of glucagon secretion). Other advantages of long-acting GLP-1 RAs include smaller fluctuations in plasma drug concentrations, improved gastrointestinal tolerability profiles, and simpler, more convenient administration schedules (once daily for liraglutide and once weekly for albiglutide, dulaglutide, the long-acting exenatide formulation, and semaglutide), which might improve treatment adherence and persistence.

Abstract
INTRODUCTION Dulaglutide (Dula) is a once-weekly glucagon-like peptide-1 receptor agonist that efficiently reduces the level of glycated hemoglobin (HbA1c) in patients with type 2 diabetes (T2D). However, the durability of the glucose-lowering effect of the first injection of Dula (1st Dula) remains unclear. METHODS This study had a retrospective, single-center, and single-arm design in a clinical setting and was conducted between April 2016 and March 2017. We investigated the changes and fluctuations in glucose level in 15 patients with T2D using a continuous glucose monitor, from 1 day before the first administration of Dula to 6 days thereafter. RESULTS The mean glucose levels decreased significantly from 1 day before 1st Dula up to 5 days thereafter, whereas the standard deviation, mean amplitude of glucose excursion, and percentage of the glucose levels > 180 mg/dL were significantly improved only up to 3, 2, and 3 days after the 1st Dula, respectively, compared to those before administration. CONCLUSION The effect of blood glucose regulation after the 1st Dula did not continue for a whole week. These effects should be considered when adjusting for other hypoglycemic agents.

Abstract
Despite the availability of long-term data demonstrating the benefits of timely and aggressive intensification of antihyperglycaemic regimens among individuals with type 2 diabetes, intensification beyond basal insulin continues to be suboptimal and a global challenge. This review summarizes the evidence surrounding the various options of advancing glucose-lowering management beyond basal insulin and provides a practical algorithm to assist in optimizing patient care and enhancing glycaemic target achievements.

J Diabetes Investig 2018; 9:831-839.

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/INTRODUCTION The glucose-lowering effects of the glucagon-like peptide-1 receptor agonist, liraglutide, have been shown to rely on remaining β-cell function. However, the possible associations of remaining β-cell function with the glucose-lowering effects of liraglutide in combination with basal insulin remain unknown and warrant investigation. MATERIALS AND METHODS This was a single-center, retrospective, observational study carried out in a private hospital in Osaka, Japan. Type 2 diabetes patients who received a prescription change from insulin therapy, both multiple-dose insulin and basal insulin-supported oral therapy, to liraglutide and basal insulin combination and continued the therapy for 54 weeks without additional oral antidiabetic drugs or bolus insulin were retrospectively analyzed. RESULTS Among the 72 participants who received a prescription change from multiple-dose insulin and basal insulin-supported oral therapy to liraglutide and basal insulin combination, 57 continued the therapy for 54 weeks. Of those who continued the therapy without receiving additional oral antidiabetic drugs or bolus insulin, seven participants achieved glycated hemoglobin < 7.0% at 54 weeks, but 30 participants did not. The participants who achieved glycated hemoglobin < 7.0% at 54 weeks had a significantly higher C-peptide immunoreactivity index, a β-cell function-related index frequently used in Japanese clinical settings. The receiver operating curve analysis showed that the C-peptide immunoreactivity index cut-off value for the achievement of glycated hemoglobin <7.0% at 54 weeks is 1.103. CONCLUSIONS The current findings show that the glucose-lowering effects of liraglutide rely on remaining β-cell function, even when used with basal insulin; and suggest that liraglutide and basal insulin combination might require additional bolus insulin to fully compensate insulin insufficiency in individuals with reduced β-cell function.

Abstract
AIMS/INTRODUCTION To determine the efficacy and safety of adding liraglutide to three different insulin regimens in Japanese patients with type 2 diabetes mellitus. MATERIALS AND METHODS In this post-hoc analysis, results from a 36-week, randomized, double-blind, placebo-controlled, parallel-group trial are reported. Individuals with type 2 diabetes mellitus were stratified according to their pre-trial insulin regimen (basal, basal-bolus and premix). The primary objective was to determine whether adding liraglutide (0.9 mg/day) to fixed-dose insulin therapy was superior vs fixed-dose insulin monotherapy, assessed by the effect on glycemic control after 16 weeks of treatment. RESULTS The treatment effect on glycated hemoglobin reduction was independent of the pre-trial insulin regimen. Comparing liraglutide with a placebo, liraglutide was associated with glycated hemoglobin reduction in all insulin regimens, with placebo-corrected reductions at 16 weeks ranging from -1.45 to -1.17%, and maintained at 36 weeks. Liraglutide resulted in a greater reduction in mean plasma glucose obtained from seven-point self-monitoring, and greater proportions of patients achieved target glycated hemoglobin. With liraglutide, slightly higher proportions of patients receiving basal and basal-bolus insulin reported confirmed hypoglycemia from 0 to 16 weeks. CONCLUSIONS The efficacy and safety of adding liraglutide to insulin therapy was confirmed, regardless of pre-trial insulin regimen.

Abstract
AIMS/INTRODUCTION To evaluate the efficacy and safety of combining insulin therapy with dipeptidyl peptidase-4 (DPP-4) inhibitors compared with combining insulin therapy with a placebo or other antihyperglycemic agents. MATERIALS AND METHODS A literature search was carried out via electronic databases. The inclusion criteria were randomized controlled trials comparing the addition of DPP-4 inhibitors to insulin with the addition of a placebo or other active hypoglycemic agents to insulin therapy, study duration of no less than 12 weeks carried out in type 2 diabetes patients and the availability of outcome data to evaluate a change in the glycated hemoglobin. RESULTS The glycated hemoglobin-lowering efficacy was significantly greater with DPP-4 inhibitor/insulin (DPP-4i/INS) than with placebo/insulin (weighted mean difference -0.53%, 95% confidence interval -0.63, -0.43, P < 0.01). The postprandial plasma glucose-lowering efficacies was also significantly greater with DPP-4i/INS than with placebo/insulin (weighted mean difference -1.65 mmol/L, 95% CI: -2.34, -0.96, P < 0.05). The risk of hypoglycemia or severe hypoglycemia was similar for DPP4i/INS and placebo/insulin treatments. There was no significant difference in the glycemia-lowering efficacy between DPP-4i/INS and alpha-glucosidase inhibitors/insulin, thiazolidinedione/insulin and glucagon-like peptide-1 receptor agonist/insulin. Sodium-glucose cotransporter 2 inhibitor/insulin treatment achieved better placebo-corrected efficacy in lowering postprandial plasma glucose, with less weight gain and no higher risk of hypoglycemia. CONCLUSIONS Treatment with DPP-4 inhibitors combined with insulin improved glycemic control without an increased risk of hypoglycemia or weight gain compared with insulin treatment alone.

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).

Trautmann ME, Vora J. Use of glucagon-like peptide-1 receptor agonists among individuals on basal insulin requiring treatment intensification. Diabet Med 2018; 35:694-706.

Abstract
As Type 2 diabetes progresses, treatment is intensified with additional therapies in an effort to manage hyperglycaemia effectively and therefore avoid complications. When greater efficacy is required, options for injectable treatments include glucagon-like peptide-1 receptor agonists and insulin, which may be added on to oral glucose-lowering treatments. Among individuals receiving long-acting basal insulin as their first injectable treatment, ~40-60% are unable to achieve or maintain their target HbA1c goals. For these people, treatment intensification options are relatively limited and include the addition of short-acting prandial insulin or a glucagon-like peptide-1 receptor agonist. Glucagon-like peptide-1 receptor agonists vary in their effects, with short- and long-acting agents having a greater impact on postprandial and fasting hyperglycaemia, respectively. Studies comparing treatment intensification options have found both glucagon-like peptide-1 receptor agonists and prandial insulin to be effective in reducing HbA1c concentrations; however, recipients of glucagon-like peptide-1 receptor agonists lost weight and had a greater frequency of gastrointestinal adverse events, whereas those receiving prandial insulin gained weight and had a greater incidence of hypoglycaemia. In addition to the separate administration of a glucagon-like peptide-1 receptor agonist and basal insulin, fixed-ratio combinations of a glucagon-like peptide-1 receptor agonist and basal insulin offer a single administration for both treatments but have less flexibility in dose titration than treatment with their individual components. For individuals who require treatment intensification beyond basal insulin, use of these various options allows physicians to target the individual needs of their patients for the achievement of optimal long-term glycaemic control.

Abstract
AIM To assess the comparative effects of glucose-lowering drugs (GLDs) on the risk of diabetic retinopathy (DR) in patients with type 2 diabetes mellitus (T2DM). METHODS We systematically searched Cochrane Central Register of Controlled Trials, PUBMED and EMBASE from inception to January 17, 2017 to identify randomized controlled trials (RCTs) that reported DR events among T2DM patients receiving any GLD. Random-effects pairwise and network meta-analyses were performed to calculate odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS A total of 37 independent RCTs with 1806 DR events among 100 928 patients with T2DM were included. The mean duration of diabetes was 8.7 years and mean baseline HbA1c was 8.2% (SD, 0.5%). Our network meta-analysis found that DPP-4i (OR, 1.20; 95% CI, 0.87-1.65), GLP-1RA (OR, 1.19; 95% CI, 0.94-1.52) and SGLT2 inhibitors (OR, 0.79; 95% CI, 0.49-1.28) were not associated with a higher risk of DR than placebo; however, a significantly increased risk of DR was associated with DPP-4i in the pairwise meta-analysis (OR, 1.27; 95% CI, 1.05-1.53). Sulfonylureas, on the other hand, were associated with a significantly increased risk of DR compared to placebo (OR, 1.67; 95% CI, 1.01-2.76). CONCLUSIONS Current evidence indicates that the association between DPP-4i, GLP-1RA or SGLT2 inhibitors and risk of DR remains uncertain in patients with T2DM. Some evidence suggests that sulfonylureas may be associated with increased risk of DR. However, given that DR events were not systematically assessed, these effects should be explored further in large-scale, well-designed studies.

Abstract
CONTEXT Insulin can be prescribed as a monotherapy or a combined therapy with other anti-diabetic medications. In this narrative review, the authors aimed to gather data related to comparison of insulin monotherapy versus combination of insulin and other anti-diabetic treatments with regards to different outcome measures in type 2 diabetes. EVIDENCE ACQUISITION This study searched and focused on the most recently published systematic reviews and their references investigating issues related to the primary aim. RESULTS The current data available on this topic is heterogeneous and suffers from low quality with respect to most combination treatments. Considering the efficacy and safety of combination therapy of insulin with older hypoglycemic agents, in general metformin and pioglitazone have the best and worst profiles, respectively. Compared to insulin monotherapy, combination of insulin and metformin is associated with better glycemic control, reduced daily insulin dose, less hypoglycemia, and weight gain; combination of insulin and pioglitazone results in greater hypoglycemia and weight gain and is associated with increased risk of edema and heart failure. Regarding sulphonylurea, there is some concern regarding hypoglycemia and weight gain. Addition of dipeptidyl peptidase-4 inhibitors to insulin seems to be beneficial with respect to glycemic control without any significant adverse effects. New drugs, including glucagon-like peptide-1 agonists and sodium glucose co-transporter 2 inhibitors, have acceptable profiles with significant benefits regarding weight reduction when added on insulin therapy. CONCLUSIONS Considering the quality and longevity of evidence, compared to insulin monotherapy, insulin combined with metformin and pioglitazone has the best and worst profiles, respectively. New anti-diabetic medications have acceptable profiles yet are expensive. It is important for clinicians to meticulously weigh the advantages of combination therapy against the possible adverse effects with each drug class in every patient, individually.

Abstract
We aimed to evaluate the comparative efficacy and safety of dipeptidyl peptidase-4 inhibitors (DPP4i), glucagon-like peptide-1 receptor agonists (GLP-1RA), sodium-glucose co-transporter 2 inhibitors (SGLT2i), or thiazolidinedione (TZD) as an adjunctive treatment in patients with poorly controlled type 2 diabetes mellitus (T2DM) on insulin therapy. We searched Medline, Embase, the Cochrane Library, and ClinicalTrials.gov through April 2016. Bayesian network meta-analyses were performed with covariate adjustment. The primary outcome was the change in glycated hemoglobin A1c (HbA1c) from baseline. Fifty randomized controlled trials covering 15,494 patients were included. GLP-1RA showed the greatest HbA1c-lowering effect compared to the control (−0.84%; 95% credible interval, −1.00% to −0.69%), followed by TZD (−0.73%; −0.93 to −0.52%), SGLT2i (−0.66%; −0.84% to −0.48%), and DPP4i (−0.54%; −0.68% to −0.39%). SGLT2i showed the greatest fasting plasma glucose reduction. GLP-1RA and SGLT2i showed greater body weight reduction, whereas TZD increased body weight. TZD was ranked the highest in terms of insulin dose reduction. The risk of hypoglycemia was increased with TZD or GLP-1RA. The study provides the best available evidence on the comparative efficacy and safety of non-insulin anti-diabetic agents on top of pre-existing insulin therapy for inadequately controlled T2DM patients.

Abstract
CONTEXT Postprandial hyperglycemia remains a challenge in type 1 diabetes (T1D) due, in part, to dysregulated increases in plasma glucagon levels after meals. OBJECTIVE This study was undertaken to examine whether 3 to 4 weeks of therapy with pramlintide or liraglutide might help to blunt postprandial hyperglycemia in T1D by suppressing plasma glucagon responses to mixed-meal feedings. DESIGN Two parallel studies were conducted in which participants underwent mixed-meal tolerance tests (MMTTs) without premeal bolus insulin administration before and after 3 to 4 weeks of treatment with either pramlintide (8 participants aged 20 ± 3 years, hemoglobin A1c 6.9 ± 0.5%) or liraglutide (10 participants aged 22 ± 3 years, hemoglobin A1c 7.6 ± 0.9%). RESULTS Compared with pretreatment responses to the MMTT, treatment with pramlintide reduced the peak increment in glucagon from 32 ± 16 to 23 ± 12 pg/mL (P < 0.02). In addition, the incremental area under the plasma glucagon curve from 0 to 120 minutes dropped from 1988 ± 590 to 737 ± 577 pg/mL/min (P < 0.001), which was accompanied by a similar reduction in the meal-stimulated increase in the plasma glucose curve from 11,963 ± 1424 mg/dL/min pretreatment vs 2493 ± 1854 mg/dL/min after treatment (P < 0.01). In contrast, treatment with liraglutide had no effect on plasma glucagon and glucose responses during the MMTT. CONCLUSIONS Adjunctive treatment with pramlintide may provide an effective means to blunt postmeal hyperglycemia in T1D by suppressing dysregulated plasma glucagon responses. In contrast, plasma glucose and glucagon responses were unchanged after 3 to 4 weeks of treatment with liraglutide.

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.

Abstract
Intestinal glucagon-like peptide-1 (GLP-1) and pancreatic insulin, released postprandially, commonly regulate glucose metabolism. Recent clinical experience indicates that the GLP-1R agonist and insulin in combination, compared to insulin alone, results in better glycemic and weight controls in type 2 diabetic patients. These observations suggest possible interactive effect of these hormones. These hormones, in addition to peripherally controlling glycemia, exert central regulation of food intake and glucose metabolism, the effect at least partly mediated by signaling to the brain via the vagal afferents. However, whether the vagal afferents are involved in the interactive effects of GLP-1 and insulin remains unknown. The present study explored possible cooperative effect of GLP-1 and insulin on vagal afferent neurons isolated from nodose ganglion (NG) of mice, while monitoring the neuronal activity by measuring cytosolic Ca2+ concentration ([Ca2+]i) with fura-2. GLP-1 at 10-8M increased [Ca2+]i in 8-11% of single NG neurons. GLP-1-induced [Ca2+]i increases were inhibited by GLP-1 receptor antagonist exendin (9-39). Majority (92%) of GLP-1-responseive NG neurons also responded to 10-7M insulin with [Ca2+]i increases. Both GLP-1 and insulin at lower concentration of 10-9M induced [Ca2+]i increases with smaller amplitude in lesser NG neuron population (4-7%). These hormones at 10-9M in combination recruited the unresponsive neurons to [Ca2+]i increases, and induced [Ca2+]i increases with greater amplitude in the responsive neurons. The results demonstrate that GLP-1 and insulin synergistically and additively activate vagal afferent neurons. This interaction may be linked to the postprandial functions mediated commonly by GLP-1 and insulin and in the beneficial outcome of the therapy with GLP-1 receptor agonist and insulin in combination.

Abstract
Most algorithms for type 2 diabetes mellitus (T2DM) do not recommend treatment escalation until glycated haemoglobin (HbA1c) fails to reach the recommended target of 7% (53 mmol/mol) within approximately 3 months on any treatment regimen ("treat to failure"). Clinical inertia and/or poor adherence to therapy contribute to patients not reaching glycaemic targets when managed according to this paradigm. Clinical inertia exists across the entire spectrum of anti-diabetes therapies, although it is most pronounced when initiating and optimizing insulin therapy. Possible reasons include needle aversion, fear of hypoglycaemia, excessive weight gain and/or the need for increased self-monitoring of blood glucose. Studies have suggested, however, that early intensive insulin therapy in newly diagnosed, symptomatic patients with T2DM with HbA1c >9% (75 mmol/mol) can preserve beta-cell function, thereby modulating the disease process. Furthermore, postprandial plasma glucose is a key component of residual dysglycaemia, evident especially when HbA1c remains above target despite fasting normoglycaemia. Therefore, to achieve near normoglycaemia, additional treatment with prandial insulin or a glucagon-like peptide-1 receptor agonist (GLP-1 RA) is often required. Long- or short-acting GLP-1 RAs offer effective alternatives to basal or prandial insulin in patients inadequately controlled with other therapies or basal insulin alone, respectively. This review highlights the limitations of current algorithms, and proposes an alternative based on the early introduction of insulin therapy and the rationale for the sequential or fixed combination of GLP-1 RAs with insulin ("treat-to-success" paradigm).

Abstract
Aims/Introduction We compared the satisfaction levels of patients with type 2 diabetes undergoing combination therapy with lixisenatide (LIX) and basal insulin with that of patients undergoing multiple daily insulin injection (MDI) therapy. Materials and Methods The study was a 12‐week open‐label, randomized, multicenter, controlled trial. Participants were Japanese patients with type 2 diabetes receiving MDI for >3 months. Patients were randomly assigned to each treatment cohort: (i) a group that continued MDI (MDI group); and (ii) a group that switched from MDI to combination therapy with LIX and basal insulin (LIX group). The primary outcome was change in Diabetes Treatment Satisfaction Questionnaire scores from baseline to 12 weeks between these two groups. Key secondary outcomes were glycated hemoglobin and body weight changes. Results A total of 31 patients were initially enrolled in the study, and 26 of them completed the study. The change in Diabetes Treatment Satisfaction Questionnaire scores in the LIX group was significantly greater compared with that in the MDI group. Mean changes in glycated hemoglobin levels were −0.05 ± 0.37% in the MDI group and 0.04 ± 0.38% in the LIX group (P = 0.36). Mean changes in body weight were +0.6 ± 1.8 kg in the MDI group and −2.5 ± 1.8 kg in the LIX group (P < 0.01). Conclusions Switching from MDI to combination therapy with LIX and basal insulin improved satisfaction levels while maintaining glycemic control in Japanese patients with type 2 diabetes.

Abstract
There is increasing evidence that the pathophysiology of type 2 diabetes mellitus (T2DM) in Asian patients differs from that in Western patients, with early phase insulin deficiencies, increased postprandial glucose excursions, and increased sensitivity to insulin. Asian patients may also experience higher rates of gastrointestinal adverse events associated with glucagon-like peptide-1 receptor agonists (GLP-1RAs), such as nausea and vomiting, compared with their Western counterparts. These factors should be taken into consideration when selecting therapy for basal insulin treatment intensification in Asian patients. However, the majority of studies to establish various agents for treatment intensification in T2DM have been conducted in predominantly Western populations, and the levels of evidence available in Chinese or Asian patients are limited. This review discusses the different mechanisms of action of short-acting, prandial, and long-acting GLP-1RAs in addressing hyperglycemia, and describes the rationale and available clinical data for basal insulin in combination with the short-acting prandial GLP-1RA lixisenatide, with a focus on treatment of Asian patients with T2DM.

Insulin and Glucagon-Like Peptide 1 Receptor Agonist Combination Therapy in Type 2 Diabetes: A Systematic Review and Meta-analysis of Randomized Controlled Trials. Diabetes Care 2017; 40:614-624. [PMID: 28325801 DOI: 10.2337/dc16-1957] [Citation(s) in RCA: 83] [Impact Index Per Article: 11.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/10/2016] [Accepted: 12/26/2016] [Indexed: 02/03/2023]
Abstract
OBJECTIVE The combination of basal insulin plus a glucagon-like peptide 1 receptor agonist (GLP-1RA) has been proposed as a treatment option to intensify insulin therapy in type 2 diabetes. We performed a meta-analysis of randomized controlled trials (RCTs) comparing this combination strategy to other injectable antidiabetes treatments on metabolic control in adult patients with type 2 diabetes. RESEARCH DESIGN AND METHODS We conducted an electronic search until November 2016 on many electronic databases to identify RCTs assessing changes in HbA1c, proportion of patients at HbA1c target ≤7% (53 mmol/mol), hypoglycemia, and weight change. We used a random-effect model to calculate the weighted mean difference (WMD) or relative risk (RR) with the 95% CI. RESULTS We identified 26 RCTs, lasting 12-52 weeks, and involving 11,425 patients. When the combination strategy was compared with other injectable treatments (overall data), there were reductions in HbA1c (WMD = -0.47%, 95% CI -0.59 to -0.35), more patients at HbA1c target (RR = 1.65, 95% CI 1.44-1.88), similar hypoglycemic events (RR = 1.14, 95% CI 0.93-1.39) and a reduction in weight (WMD = -2.5 kg, 95% CI -3.3 to -1.7), with high heterogeneity (I2 > 89%, P < 0.001) and a significant publication bias for three outcomes. In preplanned subgroup analyses, the combination treatment was similar to basal-bolus insulin regimens for glycemic control, with less hypoglycemia (RR = 0.66, 95% CI 0.46-0.93) and reduced weight (WMD = -4.7 kg, 95% CI -6.9 to -2.4). Fixed-ratio combinations yielded results similar to the overall analysis (HbA1c WMD = -0.56%, 95% CI -0.72 to -0.40). CONCLUSIONS GLP-1RAs alone or as titratable fixed-ratio combinations with basal insulin may represent a promising option to advance basal insulin therapy or to initiate injectable therapy in patients with type 2 diabetes inadequately controlled on oral agents. Longer studies are needed to assess durability and tolerability.

Abstract
Liraglutide, an analogue of human glucagon-like peptide 1, reduces cardiovascular events in patients with type 2 diabetes; however, it has still been unknown by which mechanisms liraglutide could reduce cardiovascular events. Type 2 diabetic patients with insulin treatment were enrolled in this randomized, open-label, comparative study. Participants were randomly assigned to liraglutide plus insulin (liraglutide group) and insulin treatment (control group) at 1:1 allocation. Primary endpoint was the change in viscera fat are (VFA, cm2) at 24 weeks. Liver attenuation index (LAI) measured by abdominal computed tomography, urinary albumin-to-creatinine ratio (ACR, mg/g), and C-reactive protein (CRP) levels, skeletal muscle index (SMI), and quality of life (QOL) related to diabetes treatment were also determined. Seventeen patients (8; liraglutide group, 9; control group, mean age 59 ± 13 years; 53% female) completed this study. Liraglutide treatment significantly reduced VFA at 24 weeks; whereas, SFA was unchanged. ACR, LAI, and CRP levels were significantly reduced by liraglutide at 24 weeks and there was no difference in SMI between the two groups. Changes in VFA from baseline to 24 weeks were significantly associated with those in LAI, albuminuria, and HbA1c. Liraglutide treatment significantly improved QOL scores associated with anxiety and dissatisfaction with treatment and satisfaction with treatment. No severe adverse events were observed in both groups. Our data suggest that liraglutide could reduce visceral adiposity in parallel with attenuation of hepatic fat accumulation, albuminuria and micro-inflammation and improve QOL related to diabetes care in insulin-treated patients with type 2 diabetes.

Abstract
OBJECTIVE To consolidate the evidence from randomized controlled trials evaluating the use of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) as add-on to basal insulin therapy in type 2 diabetes (T2D) patients. RESEARCH DESIGN AND METHODS We searched the EMBASE® and NCBI PubMed (Medline) databases and relevant congress abstracts for randomized controlled trials evaluating the efficacy and safety of GLP-1 RAs as add-on to basal insulin compared with basal insulin with or without rapid-acting insulin (RAI) through 23 May 2016. The pooled data were analyzed using a random-effects meta-analysis model. A subanalysis was performed for trials investigating basal insulin plus GLP-1 RAs versus basal insulin plus RAI. RESULTS Of the 2617 retrieved records, 19 randomized controlled trials enrolling 7,053 patients with T2D were included. Compared with basal insulin ± RAI, reduction in glycated hemoglobin (HbA1c) from baseline (difference in means: -0.48% [95% confidence interval (CI), -0.67 to -0.30]; p < 0.0001) and weight loss (-2.60 kg [95% CI, -3.32 to -1.89]; p < 0.0001) were significantly greater with basal insulin plus GLP-1 RA. The subanalysis similarly showed significant results for change in HbA1c from baseline and for weight loss, as well as a significantly lower risk of symptomatic hypoglycemia in patients treated with basal insulin plus GLP-1 RA versus basal insulin plus RAI (odds ratio, 0.52 [95% CI, 0.42 to 0.64]; p < 0.0001). CONCLUSIONS Addition of GLP-1 RA to basal insulin provided improved glycemic control, led to weight reduction and similar hypoglycemia rates versus an intensified insulin strategy; however, symptomatic hypoglycemia rates were significantly lower when compared with a basal insulin plus RAI.

Abstract
The effects of incretin therapies on pancreatic safety are currently being evaluated. In 3 phase 3 clinical studies of once weekly dulaglutide 0.75 mg (dulaglutide) in Japanese patients with type 2 diabetes (T2D), symptoms suggestive of acute pancreatitis as well as pancreatic enzymes were assessed and the risk of acute pancreatitis was evaluated. Patients who met any of the predefined criteria (clinical signs/symptoms of acute pancreatitis, confirmed amylase or lipase level ≥3 times the upper limit of normal [ULN], abdominal imaging of the pancreas) were adjudicated for acute pancreatitis by a blinded external committee. A total of 43 events in 40 patients (dulaglutide, 35/917 patients; liraglutide, 2/137 patients; insulin glargine, 2/180 patients; and placebo, 2/70 patients) were adjudicated (1 patient had events adjudicated during both placebo and dulaglutide treatment); 2 patients treated with dulaglutide had acute pancreatitis confirmed (2/917 [0.2%]; 2.651 patients/1,000 patient-years). One of these patients was diagnosed by the investigator with acute pancreatitis related to dulaglutide, but there was no typical abdominal pain. The event in the other patient occurred following an endoscopic ultrasound-guided fine needle aspiration. Transient increases in lipase ≥3×ULN were observed in 2% of patients in both the dulaglutide and liraglutide groups; the incidence in dulaglutide-treated patients was not significantly different from the incidences in liraglutide, placebo-, or insulin glargine-treated patients. Results of systematic assessments of pancreatic safety in 3 phase 3 studies for up to 52 weeks do not suggest an increased risk of acute pancreatitis in Japanese patients treated with dulaglutide.

Abstract
INTRODUCTION Type 2 diabetes (T2D) is a progressive disease with increasing prevalence in most countries. The majority of patients with T2D have inadequate glycaemic control, which increases the risk of diabetic complications later in life. New therapies with improved safety profiles are required to tackle the progressive nature of T2D. Areas covered: The efficacy and safety profile of IDegLira - a once-daily, fixed-ratio combination of insulin degludec and liraglutide, a glucagon-like peptide-1 receptor agonist (GLP-1RA), for the treatment of T2D - has been extensively evaluated. IDegLira's phase 3 clinical trial programme builds upon the clinical programmes of its mono-components, and their cardiovascular outcomes trials. The results are described here, focusing on different patient populations and compared with alternative insulin regimens. Expert opinion: IDegLira provides superior glycaemic control and mitigates the primary adverse effects associated with insulin therapy (weight gain and hypoglycaemia) and GLP-1RAs (gastrointestinal side effects) with no indication of additive effects. Accordingly, co-formulations such as IDegLira are likely to be increasingly preferred over stepwise addition and titration of the individual agents in the management of T2D.

Abstract
INTRODUCTION The progressive nature of type 2 diabetes necessitates treatment intensification. This often involves intensification with oral antidiabetic drugs (OADs) initially, followed by other agents, such as glucagon-like peptide-1 receptor agonists (GLP-1RAs), with the majority of patients eventually requiring insulin therapy. Therefore, this trial aimed to investigate the efficacy of IDegLira (combination of insulin degludec and liraglutide) in controlling glycemia in adults with type 2 diabetes who were inadequately controlled on a GLP-1RA and OADs. METHODS In this 26-week open-label phase 3b trial, patients on maximum-dose GLP-1RA therapy (liraglutide once daily or exenatide twice daily) with metformin alone or with pioglitazone and/or sulfonylurea were randomized 2:1 to IDegLira once daily (n = 292) or to unchanged GLP-1RA therapy (n = 146), continuing OADs at the pre-trial dose. RESULTS After 26 weeks, HbA1c reductions were superior with IDegLira versus unchanged GLP-1RA; estimated treatment difference -0.94% (-10.3 mmol/mol), p < 0.001. Mean HbA1c reduced from 7.8% to 6.4% (61.5 to 46.9 mmol/mol) with IDegLira and from 7.7 to 7.4% (60.8 to 57.1 mmol/mol) with unchanged GLP-1RA. With IDegLira, 75% and 63% of patients achieved HbA1c <7% and ≤6.5%, compared with 36% and 23% on unchanged GLP-1RA, respectively. Fasting plasma glucose and 9-point self-monitored blood glucose profiles improved significantly more with IDegLira versus unchanged GLP-1RA. The mean change in weight was +2.0 kg with IDegLira, versus -0.8 kg with unchanged GLP-1RA. Rates of confirmed hypoglycemia were low, but higher with IDegLira versus unchanged GLP-1RA. The safety profile of IDegLira was consistent with previous findings; both treatments were well tolerated and the rate of nausea was low in both groups. IDegLira improved patient-reported outcomes versus unchanged GLP-1RA. CONCLUSIONS IDegLira provided superior glycemic control versus unchanged GLP-1RA and represents an efficacious intensification approach in patients inadequately controlled on GLP-1RAs.

Abstract
The impact of antidiabetic drugs on bone metabolism is drawing increasing attention due to the discovery of a correlation between type 2 diabetes mellitus (T2DM) and osteoporosis. Glucagon-like peptide-1 (GLP-1) receptor agonists are a novel and promising class of drugs for T2DM, which may also have clinical applications in bone tissue disorders. This review examines the impact of GLP-1 on bone metabolism, including enhancement of bone mineral density and improvement of bone quality. However, the precise effect of GLP-1 on fracture risk has not been unambiguously defined. This review also summarizes our current understanding of the mechanisms by which GLP-1 affects bone metabolism. GLP-1 may act on bone by promoting bone formation, inhibiting bone resorption, and affecting the coordination of the two processes. We describe molecular pathways and proteins, such as Wnt and calcitonin, that are associated with GLP-1 and bone tissue. The specific processes and related molecular mechanisms of the effects of GLP-1 on bone metabolism need to be further explored and clarified.

Abstract
INTRODUCTION In clinical trials, liraglutide has proven to be an effective drug for the treatment of type 2 diabetes mellitus (T2DM). The real-world effectiveness of liraglutide has been investigated in numerous studies. The aim of this systematic literature review is to collate evidence on the real-world clinical effectiveness of liraglutide. METHODS A review of publications from Medline, EMBASE, the Cochrane Library, and conference proceedings was conducted to identify observational studies that assessed the clinical effectiveness of liraglutide in real-world clinical practice. This review was conducted according to the National Institute of Health and Care Excellence (NICE) guidance. No language or time limits were applied, except to the conference proceedings (2013-2015). Endpoints for data extraction were decided a priori. Study quality appraisal was done for full-text journal articles. RESULTS Of 124 publications included in the review, 43 were full-text articles. Liraglutide significantly reduces glycated hemoglobin (HbA1c) within 6 months of initiating treatment (mean change in HbA1c from baseline: -0.9% to -2.2%; HbA1c <7.0%: 29.5-65.0%). The NICE composite endpoint (HbA1c reduction ≥1% and weight reduction ≥3%) was met in 16.9-47.0% of patients with liraglutide treatment. Liraglutide therapy led to a mean change in absolute weight from baseline of -1.3 to -8.65 kg. Liraglutide treatment was well tolerated in patients with T2DM. The rate of occurrence of hypoglycemia with liraglutide monotherapy was ≤0.8%. Hypoglycemia was more common in patients taking antidiabetic medications (0.0-15.2%) together with liraglutide. The beneficial glycemic and weight effect of liraglutide therapy in patients with T2DM was maintained for at least 12 months. CONCLUSION Evidence from observational studies reflecting real-world clinical practice demonstrates that liraglutide therapy improves glycemic control with a low risk of hypoglycemia, and is associated with significant weight loss in patients with T2DM. These observations are consistent with clinical trial findings. FUNDING Novo Nordisk A/S, Søborg, Denmark.

Abstract
AIMS/INTRODUCTION To assess efficacy and safety of liraglutide in combination with insulin compared with insulin monotherapy in Japanese patients with type 2 diabetes. MATERIALS AND METHODS This was a 36-week, multicenter, double-blind, parallel-group trial, where patients on stable insulin therapy (basal/premixed/basal-bolus) were randomized 1:1 to additional liraglutide 0.9 mg/day (n = 127) or placebo (n = 130). The insulin dose was fixed for 16 weeks, and titrated based on self-measured plasma glucose thereafter. The primary end-point was change in glycosylated hemoglobin after 16 weeks. RESULTS Superiority of liraglutide plus insulin versus insulin monotherapy was confirmed based on estimated mean difference in glycosylated hemoglobin after 16 weeks of -1.30% (-14 mmol/mol; 95% confidence interval -1.47 to -1.13 [-16, -12]; P < 0.0001). Statistical significance was maintained to week 36. More patients on liraglutide achieved a glycosylated hemoglobin target of <7.0% (<53 mmol/mol) at week 16 (estimated odds ratio 50.57; 95% confidence interval 16.59 to 154.16; P < 0.0001). Improvements in seven-point self-measured plasma glucose and fasting plasma glucose were significantly greater with liraglutide than the placebo at week 16. Insulin dose after 36 weeks was lower with liraglutide than the placebo (estimated treatment ratio: 0.82 [95% confidence interval 0.76-0.90; P < 0.0001]). Occurrence of adverse events was similar in the two groups (85.8 and 81.5%, respectively); most were mild in severity. There were no significant differences in the number of hypoglycemic episodes during the 36 weeks. CONCLUSIONS Adding liraglutide to insulin results in superior glycemic control compared with insulin alone in Japanese patients with type 2 diabetes, and is generally well tolerated.
