Diabetes Obes Metab 2024; 26:3167-3175. [PMID: 38715179 DOI: 10.1111/dom.15644] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2024] [Revised: 04/19/2024] [Accepted: 04/19/2024] [Indexed: 07/10/2024]
Abstract
AIM To assess the efficacy and safety of dulaglutide 1.5 mg versus dulaglutide 0.75 mg in Japanese participants with type 2 diabetes (T2D). MATERIALS AND METHODS A Phase 3, multicentre, randomized, double-blind, parallel-group study was conducted in Japanese participants aged ≥20 years, with T2D for ≥6 months and inadequate glycaemic control, while on a single oral antihyperglycaemic medication (NCT04809220). The primary objective was to evaluate superiority of dulaglutide 1.5 mg versus dulaglutide 0.75 mg measured by mean change in glycated haemoglobin (HbA1c) from baseline to 26 weeks. Other efficacy and safety endpoints were evaluated at 26 and 52 weeks. All statistical analyses were conducted using the intention-to-treat population. RESULTS Overall, 591 participants were randomized to once-weekly dulaglutide 1.5 mg or 0.75 mg. At Week 26, dulaglutide 1.5 mg was superior to dulaglutide 0.75 mg in HbA1c reduction from baseline (least squares mean [LSM] difference -0.29% [95% confidence interval {CI} -0.43, -0.14]). At Week 52, the dulaglutide 1.5-mg arm had a significantly greater proportion of participants who achieved HbA1c <7.0% (46.3% vs. 38.5%; p = 0.03) and showed significantly greater reduction in fasting serum glucose (LSM difference -9.4 mg/dL [95% CI -14.4, -4.3]; p < 0.001) versus the dulaglutide 0.75-mg arm. No statistically significant change in body weight was observed in either treatment arm. Overall, 442 participants (75.4%) experienced treatment emergent adverse events (TEAEs). Constipation (11.3%), diarrhoea (9.6%) and pyrexia (9.0%) were the most commonly reported TEAEs. CONCLUSIONS Dulaglutide 1.5 mg once weekly demonstrated superior glycaemic control versus dulaglutide 0.75 mg once weekly, with comparable safety and tolerability, in Japanese people with T2D.

Real-World Efficacy of Glucagon-like Peptide-1 (GLP-1) Receptor Agonist, Dulaglutide, on Metabolic Parameters in Japanese Patients with Type 2 Diabetes: A Retrospective Longitudinal Study. Biomedicines 2023; 11:biomedicines11030869. [PMID: 36979848 PMCID: PMC10046001 DOI: 10.3390/biomedicines11030869] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2023] [Revised: 03/06/2023] [Accepted: 03/10/2023] [Indexed: 03/16/2023] Open
Abstract
The glucagon-like peptide-1 receptor agonist (GLP-1RA) dulaglutide has been shown to improve body weight and glycemic control and reduce major cardiovascular (CV) events. In Japan, dulaglutide is used at a fixed dose of 0.75 mg, which is lower than that in Europe and North America. However, the reports of real-world efficacy on metabolic parameters in Japanese patients with type 2 diabetes (T2DM) are limited. This study aimed to examine the real-world efficacy of GLP-1RA dulaglutide on metabolic parameters in Japanese patients with T2DM. We retrospectively selected patients with T2DM who had been prescribed dulaglutide continuously for 12 months or longer between September 2015 and December 2020 and compared metabolic parameters at baseline with the data at 12 months after the start of dulaglutide. One hundred twenty-one patients were enrolled in this study. The 12-month dulaglutide treatment reduced body weight by 1.7 kg and hemoglobin A1c by 1.1%. Significant improvements were also observed in serum high-density lipoprotein cholesterol (HDL-C), triglyceride (TG) and non-HDL-C. The change in HbA1c during dulaglutide treatment was significantly correlated with the changes in HDL-C (R = −0.236, p = 0.013), LDL-C (R = 0.377, p = 0.005) and non-HDL-C (R = 0.415, p < 0.001). The improvements in HbA1c, HDL-C, TG and non-HDL-C were greater in patients concurrently treated with SGLT2 inhibitors (SGLT2is) at baseline. In conclusion, the treatment with dulaglutide has beneficial effects on multiple CV risk factors in Japanese patients with T2DM.

Abstract
AIMS/INTRODUCTION This study evaluated the safety and effectiveness of dulaglutide in patients with type 2 diabetes in the real-world setting in Japan. MATERIALS AND METHODS This prospective, observational post-marketing surveillance study was conducted for 36 months (July 2016 to July 2021) in Japan. Investigators reported data via an electronic data capture system. Data were analyzed by overall population and age group (<65, ≥65 to <75, and ≥75 years). RESULTS The analysis population (N = 3,136) included 1,538 (49.04%), 869 (27.71%), and 729 (23.25%) patients aged <65 years, ≥65 to <75 years, and ≥75 years, respectively. Overall, 231 patients (7.37%) experienced ≥1 adverse drug reactions, with the highest frequency in the ≥75 years group. The most common adverse drug reactions were gastrointestinal disorders (n = 106; 3.38%). Severe hypoglycemia (n = 4; 0.13%), major adverse cardiovascular events (n = 4; 0.13%), and acute pancreatitis (n = 1; 0.03%) were uncommon. The mean glycated hemoglobin and bodyweight were reduced from baseline by -0.76% and -1.6 kg, respectively (last observation carried forward). The rate of dulaglutide continuation at 36 months was 58.03% overall and 59.43%, 63.13%, and 48.88% in the <65, ≥65 to <75, and ≥75 years groups, respectively. A factor analysis showed age ≥65 years was associated with a greater incidence of gastrointestinal adverse drug reactions as well as larger reductions in glycated hemoglobin and bodyweight. CONCLUSIONS The current real-world data are in accordance with clinical trial findings and further confirm the safety and effectiveness of dulaglutide for elderly patients, whose numbers were limited in the clinical trials.

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.

Lancet Diabetes Endocrinol 2020; 8:392-406. [PMID: 32333876 DOI: 10.1016/s2213-8587(20)30074-7] [Citation(s) in RCA: 103] [Impact Index Per Article: 25.8] [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
PURPOSE In East Asian patients, type 2 diabetes mellitus (T2DM) is characterized primarily by β-cell dysfunction, with lower insulin secretion than in Caucasian individuals. Therefore, bolus insulin and premixed insulin containing a bolus insulin component are important therapeutic tools in Japan, in addition to basal insulin. This subgroup analysis is stratified by insulin regimen and uses data from a phase 4, randomized, placebo-controlled, double-blind and subsequent open-label study in Japan to assess the efficacy and safety of once-weekly dulaglutide combined with various insulin therapies. METHODS This multicenter study enrolled Japanese patients with T2DM and inadequate glycemic control [glycated hemoglobin A1c (HbA1c) ≥ 7.5% to ≤ 10.5%] on insulin therapy [basal (B), premixed (PM), or basal bolus (BB)] in combination with or without one or two oral antidiabetic agents. Randomized participants received once-weekly dulaglutide 0.75 mg (n = 120) or placebo (n = 39) during a 16-week double-blind treatment period, and dulaglutide during a 36-week open-label extension. In this subgroup analysis, efficacy measures were changes from baseline in HbA1c, 7-point self-monitored blood glucose profiles, and body weight. Safety measures were incidence of adverse events and hypoglycemia during the first 16 weeks. RESULTS At week 16, least squares mean differences (95% CI) regarding changes from baseline in HbA1c for each insulin regimen versus placebo were: B: - 1.62% (- 1.96, - 1.28), PM: - 1.78% (- 2.25, - 1.30), and BB: - 1.15% (- 1.54, - 0.77); p < 0.001 dulaglutide vs. placebo for each subgroup. No significant differences in body weight changes were observed between dulaglutide and placebo for any insulin regimen. Gastrointestinal symptoms were the most commonly observed adverse events in dulaglutide-treated patients. Hypoglycemia incidence rates were: B: dulaglutide 38.5% vs. placebo 23.5%; PM: dulaglutide 38.5% vs. placebo 44.4%; BB: dulaglutide 50.0% vs. placebo 30.8%. CONCLUSIONS Overall, dulaglutide was generally well tolerated and improved glycemic control significantly versus placebo, regardless of insulin regimen.

Abstract
INTRODUCTION Although global studies have investigated the combination of dulaglutide with insulin in patients with type 2 diabetes mellitus (T2DM), differences in lean body mass and dulaglutide dosing can complicate the extrapolation of global study results to Japanese patients. This phase 4, randomized, placebo-controlled, double-blind, and subsequent open-label study aimed to assess the efficacy and safety of once-weekly dulaglutide 0.75 mg in combination with insulin therapy in patients with T2DM. METHODS Patients enrolled in this multicenter study were Japanese with T2DM who had inadequate glycemic control (HbA1c 7.5-10.5%) with insulin therapy (basal insulin, premixed insulin, or basal/mealtime insulin) in combination with or without one or two oral antidiabetic agents (OADs). Patients were randomized in a 3:1 ratio to dulaglutide or placebo. The first 16 weeks was the double-blind period with stable insulin dosing, and patients taking placebo were switched to dulaglutide for an additional 36-week open-label period in which all patients took dulaglutide (52 weeks total). RESULTS Patients (N = 159) were randomized to dulaglutide (n = 120) or placebo (n = 39). The least-squares (LS) mean changes from baseline in HbA1c at week 16 were dulaglutide - 1.45% and placebo 0.06%. The LS mean and 95% confidence interval for the difference were - 1.50% (- 1.73%, - 1.28%) and dulaglutide was superior to placebo. There were no significant differences between treatment groups in changes from baseline in body weight and insulin dose. The most frequently observed treatment-emergent adverse events in dulaglutide were nasopharyngitis, constipation, abdominal discomfort, nausea, and decreased appetite. The incidence rates of hypoglycemic events by week 16 were dulaglutide 42.5% and placebo 30.8% (P = 0.258). CONCLUSION Once-weekly dulaglutide 0.75 mg was superior to once-weekly placebo in glycemic control improvement and well tolerated in patients with T2DM in combination with insulin therapy with or without OADs.

Abstract
INTRODUCTION Dulaglutide is a recombinant glucagon-like peptide-1 immunoglobulin G4 Fc fusion protein approved for treating patients with type 2 diabetes (T2D). The aim of this study was to assess postprandial data over 4 weeks for dulaglutide (0.75 mg) versus placebo after a standardized test meal in Japanese patients with T2D. METHODS The pharmacodynamic (PD) effects of once-weekly dulaglutide (0.75 mg) in Japanese patients with T2D on diet and exercise therapy (N = 12) were evaluated by assessing postprandial data up to week 4 in a phase 4, single-center, randomized, cross-over, single-blind, placebo-controlled study. The primary end point was the change in 4-h glucose area under the concentration versus time curve [AUC (0-4 h)] from baseline to week 4. Secondary end points included changes from baseline in other PD parameters (insulin, C-peptide, glucagon, and triglycerides) at weeks 1, 2, and 4 and the safety and tolerability of dulaglutide 0.75 mg. Continuous glucose monitoring (CGM) during the 1st week was performed as an exploratory measure in each treatment period. RESULTS The decrease in AUC (0-4 h) from baseline to week 4 following dulaglutide administration was statistically significant compared with placebo at weeks 1, 2, and 4 (P < 0.0001). Insulin and C-peptide levels were also significantly increased (P < 0.05) with dulaglutide versus placebo at weeks 2 and 4. There were no statistically significant differences between groups in glucagon and triglyceride levels. Daily average glucose concentrations were decreased on the day after the first administration of dulaglutide and remained at similar levels for 4 days. The incidence of treatment-emergent adverse events was slightly higher with dulaglutide versus placebo. CONCLUSION In conclusion, dulaglutide decreased postprandial glucose from week 1 in Japanese patients with T2D, indicating that dulaglutide treatment is associated with favorable PD effects soon after treatment begins.

Abstract
Elevation of postprandial plasma glucose is correlated with an increase in cardiovascular events, and alpha-glucosidase inhibitors (αGIs) are effective at reducing postprandial glucose levels. In Japan, the αGIs acarbose, voglibose, and miglitol have been available since 1993, 1994, and 2006, respectively. Dipeptidyl peptidase-4 (DPP-4) inhibitors are also effective at reducing postprandial glucose levels, and they have been available in Japan since 2009. A combination therapy of αGI, miglitol, and the DPP-4 inhibitor, sitagliptin, is more effective at decreasing postprandial glucose levels than monotherapy with either miglitol or sitagliptin. Moreover, the combination therapy of miglitol and sitagliptin is more effective at increasing postprandial active glucagon-like peptide-1 (GLP-1) levels than monotherapy. Peptide YY (PYY) has appetite-suppressing and gastric-emptying effects similar to GLP-1. In healthy individuals, miglitol increases the postprandial total PYY; however, combination therapy of miglitol and vildagliptin does not change postprandial total PYY levels. αGIs are typically prescribed to be taken just before a meal, which can result in decreased drug adherence. Different patterns of αGI intake were examined, and the results showed that miglitol or acarbose administration after a meal is effective. The effects of taking miglitol dissolved in water during a meal appeared to be similar to that of taking miglitol as a tablet just before a meal. The long-term effects of taking miglitol dissolved in water should be evaluated in future studies. αGIs may be effective even when they are not taken before a meal, and a more flexible administration may improve drug adherence.

Abstract
AIMS/INTRODUCTION We compared treatment satisfaction in type 2 diabetes patients taking daily and weekly glucagon-like peptide-1 receptor agonists. MATERIALS AND METHODS The study was a 12-week, multicenter, open-label, prospective, randomized, parallel-group comparison trial. The participants were Japanese patients with type 2 diabetes being administered with the glucagon-like peptide-1 receptor agonist, liraglutide, daily for >3 months. Patients were randomly assigned to either continue taking liraglutide once daily (Lira group) or switch to dulaglutide once weekly (Dula group). The primary outcome was the change in the Diabetes Treatment Satisfaction Questionnaire score from baseline to week 12 in the two groups. The secondary outcomes comprised changes in the Diabetes Therapy-Related Quality of Life score, body mass and glycemic control. RESULTS A total of 33 participants were initially enrolled in the trial, and 31 participants completed the protocol. The change in the Diabetes Treatment Satisfaction Questionnaire score in the Dula group was significantly greater than that in the Lira group (+0.1 ± 4.7 in the Lira group vs +4.9 ± 5.2 in the Dula group; P = 0.013). The change in Diabetes Therapy-Related Quality of Life score in the Dula group was significantly greater than that in the Lira group (-3.7 ± 6.9 vs +8.9 ± 15.1; P = 0.007). There were no significant differences between groups in the changes in body mass, plasma glucose or glycated hemoglobin. CONCLUSIONS Weekly administration of dulaglutide was superior to liraglutide with regard to treatment satisfaction in patients with type 2 diabetes, in the absence of any negative effect on glycemic control.

Abstract
INTRODUCTION To compare the effect of dulaglutide and liraglutide on oxidative stress and endothelial function in patients with type 2 diabetes mellitus (T2DM). METHODS Twenty-two patients with T2DM who received treatment with liraglutide for at least 12 weeks were randomized to either continue liraglutide or receive dulaglutide for 24 weeks. The primary end points were changes in the diacron-reactive oxygen metabolite (d-ROMs) test, as a marker of oxidative stress, and endothelial function, as determined by the reactive hyperemia index (RHI). The secondary end points were changes in body weight (BW), glucose variability, diabetes treatment satisfaction questionnaire (DTSQ) score, and eating behavior. RESULTS There were no significant differences in changes in d-ROMs and logarithmic-scaled RHI (L-RHI) between the two groups after 24 weeks of treatment. Notably, the treatment with dulaglutide was superior to that with liraglutide in terms of mean glucose levels and mean amplitude of glycemic excursions following the 24-week treatment. However, in this regard, the outcome following the treatment with dulaglutide was maintained, whereas that with the treatment with liraglutide was aggravating. The DTSQ score for "convenience" improved in the dulaglutide group. No statistically significant changes in fasting plasma glucose, hemoglobin A1c, and BW were observed between the two groups. CONCLUSION We showed that once-weekly dulaglutide was comparable to once-daily liraglutide in terms of oxidative stress and endothelial function. Switching from liraglutide to dulaglutide improved convenience by decreasing the number of injections without deteriorating glucose metabolism. TRIAL REGISTRATION This trial was registered with the University Hospital Medical Information Network (UMIN no. 000034353) on 10 October 2018.

Abstract
Dulaglutide is a once-weekly glucagon-like peptide-1 receptor agonist, which has been on the market in the USA since 2014. Dulaglutide has performed well in head-to-head studies against metformin, glargine, and sitagliptin, where its A1c lowering ranged from -0.78% to -1.64% over 52-104 weeks, and it consistently outperformed each of these agents. As an add-on therapy, dulaglutide provided additional A1c lowering of -1.4% to -1.44% over monotherapy with glimepiride or glargine at 24 and 28 weeks, respectively. Dulaglutide outperformed exenatide when added to a regimen of metformin with pioglitazone as well as glargine when added to a regimen of metformin with glimepiride. Dulaglutide was shown to be non-inferior to liraglutide when added to metformin. In all AWARD studies other than when compared to liraglutide, dulaglutide at full strength resulted in significantly more patients achieving their A1c goal. Recent class-wide meta-analyses indicate that the incidence of commonly experienced gastrointestinal (GI) side effects is dose dependent, and nausea and vomiting are less common in longer-acting agents such as dulaglutide, but diarrhea may be more common. Pooled data have shown no increased risk of serious side effects such as pancreatitis or neoplasm with the use of dulaglutide. Given the evidence supporting liraglutide's cardiovascular benefits, the highly anticipated REWIND trial will have a significant impact on the future place in the therapy of dulaglutide.

Abstract
INTRODUCTION This analysis investigated the relationship between baseline fasting pancreatic β-cell function and efficacy in Japanese patients with type 2 diabetes (T2D) treated with once-weekly dulaglutide 0.75 mg (dulaglutide) or once-daily liraglutide 0.9 mg (liraglutide) for up to 52 weeks. METHODS In a 52-week study of monotherapy in Japanese patients with T2D, patients were categorized into three subgroups defined by tertiles (low, medium, and high) of baseline values of three pancreatic β-cell function parameters [fasting C-peptide, C-peptide index, and secretory units of islets in transplantation (SUIT) index]. Associations between these parameters and efficacy [defined by changes from baseline in glycated hemoglobin (HbA1c), fasting blood glucose (FBG), postprandial blood glucose (PBG), mean of all meals blood glucose excursion, and body weight] in the dulaglutide group (280 patients) or the liraglutide group (137 patients) were evaluated. RESULTS Patients in the subgroups with high insulin-secreting ability (based on pancreatic β-cell function) were younger and had shorter disease duration and higher body mass index compared to those with low insulin-secreting ability. No specific trend was observed between baseline pancreatic β-cell function and changes in HbA1c or FBG. Reductions from baseline in mean PBG and excursion were greatest for patients in the low β-cell function tertiles. Inconsistent trends in body weight were observed across the treatment groups and β-cell function parameters. CONCLUSION In Japanese patients with T2D, changes in HbA1c and body weight after 52 weeks of treatment with dulaglutide or liraglutide could not be predicted by patients' fasting pancreatic β-cell function before treatment.

Abstract
We analyzed the efficacy and safety of once weekly dulaglutide 0.75 mg by sex in 2 randomized, controlled phase 3 studies in Japanese patients with type 2 diabetes (a 52-week monotherapy study [comparator liraglutide 0.9 mg] and a 26-week combination therapy study [comparator insulin glargine]). Females comprised 18% of patients in the monotherapy study and 29% of patients in the combination therapy study. Mean reductions from baseline in glycated hemoglobin (HbA1c) were similar between the sexes for dulaglutide- and liraglutide-treated patients (range -1.17% to -1.49%). Females had numerically greater weight loss or less weight gain than males across all treatment groups. The percentages of patients with reductions in both HbA1c and weight from baseline were also greater for females than for males in all treatment groups. In all treatment groups, the incidences of treatment-emergent adverse events tended to be greater among females than among males. No differences in the incidences of total or nocturnal hypoglycemia were observed between the sexes in any treatment group. Overall, in 2 studies in Japan, across all treatment groups it appeared that HbA1c lowering was unaffected by patient sex, while female patients had greater weight loss or less weight gain and greater incidence of adverse events, including nausea, compared to male patients. Incidences of patients discontinuing dulaglutide early due to adverse event were low (<10%) for both sexes, and no new safety concerns related to dulaglutide were identified for either sex. Therefore, the benefit/risk ratio for dulaglutide remains unchanged, positive for both sexes.

Abstract
In 855 Japanese patients with type 2 diabetes receiving once weekly dulaglutide 0.75 mg in 3 phase 3 studies, the effects on efficacy and safety at week 26 (last observation carried forward) were investigated in a post hoc descriptive analysis of subgroups of age (<65 years [young], ≥65 years [elderly]) and body mass index (BMI [<25 kg/m2, ≥25 kg/m2]). The 4 subgroups were as follows: 1) the young/low-BMI subgroup (Y/L) (n = 255); 2) the young/high-BMI subgroup (Y/H) (n = 386), 3) the elderly/low-BMI subgroup (E/L) (n = 137), and 4) the elderly/high-BMI subgroup (E/H) (n = 77). The mean changes from baseline in glycated hemoglobin (HbA1c) and body weight, respectively, were -1.69% and -0.29 kg in the Y/L subgroup; -1.48% and -0.09 kg in the Y/H subgroup; -1.68% and -0.20 kg in the E/L subgroup; and -1.72% and -0.26 kg in the E/H subgroup. The incidences of nausea and hypoglycemia, respectively, were 6.7% and 11.0% in the Y/L subgroup; 7.0% and 8.0% in the Y/H subgroup; 10.2% and 18.2% in the E/L subgroup; and 3.9% and 22.1% in the E/H subgroup. Dulaglutide improved HbA1c regardless of age or BMI; a higher incidence of hypoglycemia was observed in elderly patients compared to younger patients.

Abstract
Liver-related diseases are the leading causes of death in patients with type 2 diabetes mellitus (T2DM) in Japan. Type 2 diabetes mellitus is closely associated with non-alcoholic fatty liver disease (NAFLD), which is the most prevalent chronic liver disease worldwide. Non-alcoholic steatohepatitis (NASH), a severe form of NAFLD, can lead to hepatocellular carcinoma and hepatic failure. Non-alcoholic steatohepatitis can be called "diabetic hepatopathy". There are no established pharmacotherapies for NAFLD/NASH patients with T2DM. Although metformin is established as the first-line therapy for T2DM, given its relative safety and beneficial effects on glycosylated hemoglobin, weight, and cardiovascular mortality, this agent is not recommended as specific therapy for NASH/NAFLD due to lack of clinical evidence. The effects of pioglitazone on NASH histology with T2DM have been extensively proved, but several concerns exist, such as body weight gain, fluid retention, cancer incidence, and bone fracture. In recent years, novel antidiabetic medications have been approved for T2DM, such as glucagon-like peptide 1 receptor agonists, dipeptidyl peptidase 4 inhibitors, and sodium/glucose cotransporter 2 inhibitors. A key clinical question for hepatologists is what kinds of antidiabetic medications are the most appropriate for the treatment of NAFLD accompanied by T2DM, to prevent progression of hepatic fibrosis resulting in HCC/liver-related mortality without increased risk of cardiovascular events. This review focuses on novel antidiabetic agents and future perspectives on the treatment of NAFLD/NASH with T2DM.

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
The efficacy and safety of once-weekly dulaglutide 0.75 mg (dulaglutide) in Japanese patients with type 2 diabetes (T2D) were evaluated according to subgroups defined by concomitant oral hypoglycaemic agents. This exploratory analysis included data from a randomized, open-label, phase III study that compared dulaglutide with insulin glargine (glargine) (n = 361). The three subgroups were dulaglutide or glargine in combination with sulphonylurea (SU) alone, biguanide (BG) alone or SU and BG combined. There were no clinically relevant differences in glycated haemoglobin (HbA1c) changes among the three subgroups in the dulaglutide group; in the glargine group, a numerically greater reduction was observed in combination with BG alone compared to the other two groups (SU alone and SU + BG). Weight loss was observed with dulaglutide in combination with BG alone or with SU + BG. The incidence of adverse events among subgroups was significantly different in the glargine group but not in the dulaglutide group. Incidence of hypoglycaemia was highest in combination with SU for both treatments. For patients with T2D, dulaglutide added to concomitant BG may be more likely to result in weight loss than dulaglutide added to concomitant SU.

Abstract
OBJECTIVE To investigate the efficacy and safety of liraglutide added to capped insulin doses in subjects with type 1 diabetes. RESEARCH DESIGN AND METHODS A 26-week, placebo-controlled, double-blind, parallel-group trial enrolling 835 subjects randomized 3:1 receiving once-daily subcutaneous liraglutide (1.8, 1.2, and 0.6 mg) or placebo added to an individually capped total daily dose of insulin. RESULTS Mean baseline glycated hemoglobin (HbA1c) (8.1% [65.0 mmol/mol]) was significantly decreased with liraglutide versus placebo at week 26 (1.8 mg: -0.33% [3.6 mmol/mol]; 1.2 mg: -0.22% [2.4 mmol/mol]; 0.6 mg: -0.23% [2.5 mmol/mol]; placebo: 0.01% [0.1 mmol/mol]). Liraglutide significantly reduced mean body weight (-5.1, -4.0, and -2.5 kg for 1.8, 1.2, and 0.6 mg, respectively) versus placebo (-0.2 kg). Significant reductions in daily insulin dose and increases in quality of life were seen with liraglutide versus placebo. There were higher rates of symptomatic hypoglycemia (21.3 vs. 16.6 events/patient/year; P = 0.03) with liraglutide 1.2 mg vs. placebo and of hyperglycemia with ketosis >1.5 mmol/L with liraglutide 1.8 mg vs. placebo (0.5 vs. 0.1 events/patient/year; P = 0.01). CONCLUSIONS In a broad population of subjects with long-standing type 1 diabetes, liraglutide added to capped insulin reduced HbA1c, body weight, and insulin requirements but with higher rates of hypoglycemia for liraglutide 1.2 mg and hyperglycemia with ketosis for liraglutide 1.8 mg.

Abstract
OBJECTIVE To investigate whether liraglutide added to treat-to-target insulin improves glycemic control and reduces insulin requirements and body weight in subjects with type 1 diabetes. RESEARCH DESIGN AND METHODS A 52-week, double-blind, treat-to-target trial involving 1,398 adults randomized 3:1 to receive once-daily subcutaneous injections of liraglutide (1.8, 1.2, or 0.6 mg) or placebo added to insulin. RESULTS HbA1c level was reduced 0.34-0.54% (3.7-5.9 mmol/mol) from a mean baseline of 8.2% (66 mmol/mol), and significantly more for liraglutide 1.8 and 1.2 mg compared with placebo (estimated treatment differences [ETDs]: 1.8 mg liraglutide -0.20% [95% CI -0.32; -0.07]; 1.2 mg liraglutide -0.15% [95% CI -0.27; -0.03]; 0.6 mg liraglutide -0.09% [95% CI -0.21; 0.03]). Insulin doses were reduced by the addition of liraglutide 1.8 and 1.2 mg versus placebo (estimated treatment ratios: 1.8 mg liraglutide 0.92 [95% CI 0.88; 0.96]; 1.2 mg liraglutide 0.95 [95% CI 0.91; 0.99]; 0.6 mg liraglutide 1.00 [95% CI 0.96; 1.04]). Mean body weight was significantly reduced in all liraglutide groups compared with placebo ETDs (1.8 mg liraglutide -4.9 kg [95% CI -5.7; -4.2]; 1.2 mg liraglutide -3.6 kg [95% CI -4.3; -2.8]; 0.6 mg liraglutide -2.2 kg [95% CI -2.9; -1.5]). The rate of symptomatic hypoglycemia increased in all liraglutide groups (estimated rate ratios: 1.8 mg liraglutide 1.31 [95% CI 1.07; 1.59]; 1.2 mg liraglutide 1.27 [95% CI 1.03; 1.55]; 0.6 mg liraglutide 1.17 [95% CI 0.97; 1.43]), and hyperglycemia with ketosis increased significantly for liraglutide 1.8 mg only (event rate ratio 2.22 [95% CI 1.13; 4.34]). CONCLUSIONS Liraglutide added to insulin therapy reduced HbA1c levels, total insulin dose, and body weight in a population that was generally representative of subjects with type 1 diabetes, accompanied by increased rates of symptomatic hypoglycemia and hyperglycemia with ketosis, thereby limiting clinical use in this group.

Odawara M, Miyagawa J, Iwamoto N, Takita Y, Imaoka T, Takamura T. Once-weekly glucagon-like peptide-1 receptor agonist dulaglutide significantly decreases glycated haemoglobin compared with once-daily liraglutide in Japanese patients with type 2 diabetes: 52 weeks of treatment in a randomized phase III study. Diabetes Obes Metab 2016; 18:249-57. [PMID: 26661514 PMCID: PMC5064615 DOI: 10.1111/dom.12602] [Citation(s) in RCA: 41] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2015] [Revised: 09/18/2015] [Accepted: 10/28/2015] [Indexed: 01/14/2023]
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
BACKGROUND Medication complexity/burden can be associated with nonadherence in patients with type 2 diabetes mellitus (T2DM). Patients' satisfaction with their treatment is an important consideration for physicians. Strategies like using longer acting efficacious agents with less frequent dosing may help adherence. OBJECTIVE To explore the mode of administration of dulaglutide and its implications for treatment adherence in T2DM. METHODS PubMed search using the term "Dulaglutide" through October 31, 2015 was conducted. Published articles, press releases, and abstracts presented at national/international meetings were considered. RESULTS/CONCLUSION Dulaglutide is a once-weekly glucagon like peptide-1 analog with a low intraindividual variability. Phase III trials demonstrated significant improvements in glycemia and weight, with a low hypoglycemia risk similar to liraglutide/exenatide, but with substantially fewer injections. A significant improvement was observed in the total Diabetes Treatment Satisfaction Questionnaire score, Impact of Weight on Self-Perception, and perceived frequency of hyperglycemia with dulaglutide when compared with placebo, exenatide, liraglutide, or metformin. Treatment satisfaction scores showed an improvement with dulaglutide (34%-39%) when compared with exenatide (31%). A positive experience with a high initial (97.2%) and final (99.1%) injection success rate along with a significant reduction in patients' fear of self-injecting, as measured by the modified self-injecting subscale of the Diabetes Fear of Injecting and Self-Testing Questionnaire and Medication Delivery Device Assessment Battery, was found. Its acceptance was high (>96%) among a variety of patients including patients who fear injections and injection-naïve users. Dulaglutide is available as a single-dose automatic self-injecting device, which has a low volume, does not need reconstitution, and avoids patient handling of the needle. Dose adjustment based on weight, sex, age, race, ethnicity, or injection-site is not necessary. In chronic diseases like diabetes where patients need lifelong medications, the efficacy, safety, and convenience of a once-weekly, easy-to-use, self-injecting device should encourage patient adherence to dulaglutide therapy.

Abstract
The efficacy and tolerability of once weekly dulaglutide 0.75 mg in Japanese patients with type 2 diabetes (T2D) were evaluated by subgroups defined by key demographic characteristics. This post hoc analysis included data from patients who received dulaglutide 0.75 mg for up to 26 weeks in three phase 3 trials (one open-label, randomized; one double-blind and open-label, randomized; one open-label, nonrandomized). Patients were classified into subgroups on the basis of sex (male, female), age (<65, ≥65 years), body weight (<70, ≥70 kg), body mass index (BMI; <25, ≥25 kg/m(2)), duration of diabetes (<7, ≥7 years), HbA1c (≤8.5, >8.5%), use of concomitant sulfonylurea (yes, no), and use of concomitant biguanide (yes, no). Efficacy measures analyzed were changes from baseline in HbA1c and body weight and percentages of patients achieving HbA1c <7.0%. Safety measures analyzed were incidence of hypoglycemia and nausea and change from baseline in seated pulse rate. A total of 855 patients were analyzed. Once weekly dulaglutide 0.75 mg improved blood glucose control as measured by HbA1c regardless of patient characteristics; patients with higher baseline HbA1c values had greater improvements compared to patients with lower baseline values. Weight loss was greater in patients with lower baseline HbA1c and in patients taking concomitant biguanides. Concomitant use of sulfonylureas had the greatest effect on the incidence of hypoglycemia. Treatment of T2D with once weekly dulaglutide 0.75 mg for 26 weeks was associated with significant improvement in glycemic control irrespective of age, sex, duration of diabetes, body weight, BMI, or concomitant medication.
