GLP-1 receptor agonists in the treatment of type 2 diabetes - state-of-the-art.
GLP-1 receptor agonists (GLP-1 RAs) with exenatide b.i.d. first approved to treat type 2 diabetes in 2005 have been further developed to yield effective compounds/preparations that have overcome the original problem of rapid elimination (short half-life), initially necessitating short intervals between injections (twice daily for exenatide b.i.d.).. To summarize current knowledge about GLP-1 receptor agonist.

Ectopic insulinoma diagnosed by 68Ga-Exendin-4 PET/CT: A case report and review of literature.
Ectopic insulinomas are extremely rare and challenging to diagnose for clinicians. Precise preoperative localization is essential to successful treatment.. A 23-year-old man presented with a 1-year history of recurrent hypoglycemia.. Examinations in the local hospital did not reveal any pancreatic lesion. After admission, a fasting test and a 5-hour oral glucose tolerance test (OGTT) suggested a diagnosis of endogenous hyperinsulinemic hypoglycemia. Enhanced volume perfusion computed tomography (VPCT) revealed 2 nodules in the tail of the pancreas, a nodule in the gastric antrum, and a nodule in the hilum of the spleen. To differentiate which nodule was responsible for hypoglycemia, we performed 68Ga-Exendin-4 PET/CT and 68Ga-DOTATATE PET/CT which helped to make a conclusive diagnosis that the lesion in the gastric antrum was an ectopic insulinoma.. The patient was cured with minimally invasive laparoscopic resection of the tumor.. The symptoms were relieved and the blood glucose level remained normal after surgery.. This case shows that 68Gallium-exendin-4 PET/CT is useful for precise localization and thereby successful treatment of insulinoma, especially for occult insulinomas and those derived from an ectopic pancreas.

Glucagon-like peptide 1 receptor agonists in type 1 diabetes mellitus.
The role of glucagon-like peptide 1 receptor agonists (GLP-1 RAs) in the treatment of type 1 diabetes mellitus (T1DM), including efficacy and safety evidence, is reviewed.. Currently approved treatment options for glycemic control in T1DM include insulin, which combats insulin deficiency but does not effectively target disease progression or alpha cell dysfunction; and pramlintide, whose use requires multiple daily doses and involves a high likelihood of gastrointestinal side effects. GLP-1 RAs have a unique mechanism of action in T1DM, addressing alpha cell dysfunction and thereby suppressing inappropriate glucagon secretion. GLP-1 RA dosing varies from once weekly to twice daily, and the class is well tolerated in patients with type 2 diabetes. Among the GLP-1 RAs, exenatide and liraglutide have been studied in patients with T1DM, with published evidence consistently demonstrating weight loss, decreases in total daily insulin requirements, and modest improvements in glycemic control. GLP-1 RA therapy appears to be well tolerated in patients with T1DM and is associated with nonsignificant increases in hypoglycemia risk.. GLP-1 RA therapy represents an important add-on therapy option for achieving decreased insulin doses, weight loss, and modest improvements in HbA1c levels without significantly increasing hypoglycemia risk in patients with T1DM. Patients who have detectable C-peptide and/or are overweight or cannot achieve glycemic goals without hypoglycemia have been found to benefit the most from GLP-1 RA therapy. Further studies are warranted to evaluate these agents' potential impact on clinical outcomes such as microvascular and macrovascular complications.

Pharmacokinetic drug evaluation of exenatide for the treatment of type 2 diabetes.
Glucagon-like peptide-1 (GLP-1) receptor analogs are a group of therapeutic agents which mimic endogenous GLP-1, exerting their effect by the stimulation of the GLP-1 receptor with a wide distribution. Its activation increases insulin releasing dependent on blood glucose levels, suppression of glucagon secretion and a reduction of hepatic glucose output. It delays gastric emptying and increases satiety. Exenatide is the synthetic version of exendin-4, a natural peptide with similar properties to human GLP-1. There are two pharmaceutical forms, for subcutaneous injection: twice daily and once weekly. Clinical practice guidelines recommend them because of a high efficacy reducing hyperglycemia, low risk of hypoglycemia and a significative weight loss effect. Gastrointestinal adverse events are the most common beside injection site-related. Their cost is the main limitation to use. Areas covered: We review the recent literature investigating the pharmacokinetics and pharmacodynamics and efficacy-safety studies of exenatide twice daily and once weekly in type 2 diabetes Expert opinion: GLP-1 receptor analogs are now positioned as an effective and safe drug for the treatment of type 2 diabetes. Exenatide significally reduces HbA1c and fasting plasma glucose. Additionally, it produces moderate weight loss and decreases blood pressure. One weekly formulation may improve compliance while cost is still a limitation. EXSCEL trial has shown that, despite cardiovascular safety, exenatide do not exhibits cardiovascular benefits.

Safety of Once-weekly Glucagon-like Peptide-1 Receptor Agonists in Patients with Type 2 Diabetes.
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have been found efficacious in the treatment of type 2 diabetes (T2D), demonstrating the ability to lower HbA1c, and having the potential for inducing weight loss and reducing the risk of hypoglycemia, compared with other antihyperglycemic agents. Currently, 4 once-weekly (OW) GLP-1 RAs are approved: albiglutide, dulaglutide, exenatide ER, and recently, semaglutide. This review compares the relative safety of OW GLP-1 RAs, as well as their safety in comparison to other antihyperglycemic agents, using safety data reported in key sponsor-led phase 3 studies of the 4 OW GLP-1 RAs. The favorable safety profiles of OW GLP-1 RAs, added to their efficacy and the favorable weekly dosing regimen, make these agents appropriate options for patients with T2D. However, there are key differences within this class of drugs in macrovascular, microvascular, gastrointestinal and injection-site reaction adverse events, and these should be considered when healthcare providers are prescribing therapy.

A Review of the Long-Term Efficacy, Tolerability, and Safety of Exenatide Once Weekly for Type 2 Diabetes.
Exenatide once weekly (ExeOW, Bydureon. Data concerning treatment of T2D with ExeOW are reviewed with special reference to its long-term efficacy, tolerability, and safety. Relevant literature was identified through the PubMed database from inception to January 2015.. In randomized clinical trials ExeOW, as add-on to oral antidiabetics, achieved significantly improved glycemic control compared to maximum recommended doses of exenatide twice daily, sitagliptin, pioglitazone, and insulin glargine, as measured by HbA1c. In drug-naïve patients ExeOW was superior to sitagliptin and non-inferior to metformin, whereas non-inferiority to pioglitazone and liraglutide was not proven. In different trials reductions in HbA1c ranged from -1.1% to -2.0%. ExeOW therapy over 6 months was also associated with a mean weight loss of -2 to -4 kg, improved systolic blood pressure and lipid profile, and no hypoglycemia unless associated to sulfonylurea. ExeOW long-term therapy up to 3-6 years allowed persistent glycemic control (HbA1c -1.6%), sustained decreases in blood pressure (-2 mmHg), and improvements of lipid profile. ExeOW tolerability was comparable to that of the other GLP-1 receptor agonists, with better gastrointestinal tolerability when direct comparison was done (namely liraglutide and exenatide BID), but higher incidence of injection site reactions and few treatment discontinuations mainly due to gastrointestinal events.. ExeOW is a well-tolerated and convenient option for long-term treatment of T2D allowing significant and persistent glycemic control with moderate weight loss and low risk of hypoglycemia unless associated with sulfonylureas.

Glucagon-like peptide-1 receptor agonists compared with basal insulins for the treatment of type 2 diabetes mellitus: a systematic review and meta-analysis.
Since 2005, several glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have been approved to treat people with type 2 diabetes. These agents are considered for use at the same point in the treatment paradigm as basal insulins. A comprehensive comparison of these drug classes, therefore, can help inform treatment decisions. This systematic review and meta-analysis assessed the clinical efficacy and safety of GLP-1 RAs compared with basal insulins.. MEDLINE, EMBASE, CENTRAL and PubMed databases were searched. Randomized clinical trials (RCTs) of ≥16 weeks' duration comparing GLP-1 RAs vs basal insulins in adults with type 2 diabetes inadequately controlled with oral antihyperglycemic drugs were included. Data on the change from baseline to 26 weeks (±10 weeks) of treatment in hemoglobin A1c (HbA1c) and weight, as well as the proportion of patients experiencing hypoglycaemia, were extracted. Fixed-effect pairwise meta-analyses were conducted where data were available from ≥2 studies.. Fifteen RCTs were identified and 11 were meta-analysed. The once-weekly GLP-1 RAs, exenatide long acting release (LAR) and dulaglutide, led to greater, statistically significant mean HbA1c reductions vs basal insulins (exenatide: -0.31% [95% confidence interval -0.42, -0.19], dulaglutide: -0.39% [-0.49, -0.29]) whilst once-daily liraglutide and twice-daily exenatide did not (liraglutide: 0.06% [-0.06, 0.18], exenatide: 0.01% [-0.11, 0.13]). Mean weight reduction was seen with all GLP-1 RAs while mean weight gain was seen with basal insulins. Interpretation of the analysis of hypoglycaemia was limited by inconsistent definitions and reporting. Because of the limited number of available studies sensitivity analyses to explore heterogeneity could not be conducted.. Although weight reduction is seen with all GLP-1 RA's, only the once-weekly agents, exenatide LAR and dulaglutide, demonstrate significant HbA1c reductions when compared to basal insulins.

A meta-analysis comparing clinical effects of short- or long-acting GLP-1 receptor agonists versus insulin treatment from head-to-head studies in type 2 diabetic patients.
To study differences in clinical outcomes between initiating glucagon-like peptide-1 receptor agonist (GLP-1 RAs) vs insulin treatment in patients with type 2 diabetes treated with oral glucose-lowering medications (OGLM).. Prospective, randomized trials comparing GLP-1 RA and insulin treatment head-to-head as add-on to OGLM were identified (PubMed). Differences from baseline values were compared for HbA1c, fasting plasma glucose, bodyweight, blood pressure, heartrate and lipoproteins. Proportions of patients reporting hypoglycaemic episodes were compared.. Of 712 publications identified, 23 describing 19 clinical trials were included in the meta-analysis. Compared to insulin, GLP-1 RAs reduced HbA1c more effectively (Δ -.12%, P < .0001). Basal insulin was more effective in reducing fasting plasma glucose (Δ -1.8 mmol/L, P < .0001). GLP-1 RAs reduced bodyweight more effectively (Δ -3.71 kg; P < .0001). The proportion of patients experiencing hypoglycaemic episodes was 34% lower with GLP-1 RAs ( P < .0001), with a similar trend for severe hypoglycaemia. Systolic blood pressure was lower and heartrate was higher with GLP-1 RAs ( P < .0001). Triglycerides and LDL cholesterol were significantly lower with GLP-1 RAs. Long-acting GLP-1 RAs were better than short-acting GLP-1 RAs in reducing HbA1c and fasting glucose, but were similar regarding bodyweight.. Slightly better glycaemic control can be achieved by adding GLP-1 RAs to OGLM as compared to insulin treatment, with added benefits regarding bodyweight, hypoglycaemia, blood pressure and lipoproteins. These differences are in contrast to the fact that insulin is prescribed far more often than GLP-1 RAs.

Efficacy and safety of glucagon-like peptide-1 receptor agonists in type 2 diabetes: A systematic review and mixed-treatment comparison analysis.
To compare efficacy and safety of glucagon-like peptide-1 receptor agonists (GLP-1RAs) in people with type 2 diabetes.. We electronically searched, up to June 3, 2016, published randomized clinical trials lasting between 24 and 32 weeks that compared a GLP-1RA (albiglutide, dulaglutide, twice-daily exenatide and once-weekly exenatide, liraglutide, lixisenatide, semaglutide and taspoglutide) with placebo or another GLP-1RA. Data on cardiometabolic and safety outcomes were analysed using a mixed-treatment comparison meta-analysis.. A total of 34 trials (14 464 participants) met the inclusion criteria; no published data for semaglutide were available. Compared with placebo, all GLP-1RAs reduced glycated haemoglobin (HbA1c) and fasting plasma glucose (FPG) levels (reductions ranged from -0.55% and -0.73 mmol/L, respectively, for lixisenatide to -1.21% and -1.97 mmol/L, respectively, for dulaglutide). There were no differences within short-acting (twice-daily exenatide and lixisenatide) or long-acting (albiglutide, dulaglutide, once-weekly exenatide, liraglutide and taspoglutide) groups. Compared with twice-daily exenatide, dulaglutide treatment was associated with the greatest HbA1c and FPG reduction (0.51% and 1.04 mmol/L, respectively), followed by liraglutide (0.45% and 0.93 mmol/L, respectively) and once-weekly exenatide (0.38% and 0.85 mmol/L, respectively); similar reductions were found when these 3 agents were compared with lixisenatide. Compared with placebo, all GLP-1RAs except albiglutide reduced weight and increased the risk of hypoglycaemia and gastrointestinal side effects, and all agents except dulaglutide and taspoglutide reduced systolic blood pressure. When all GLP-1RAs were compared with each other, no clinically meaningful differences were observed in weight loss, blood pressure reduction or hypoglycaemia risk. Albiglutide had the lowest risk of nausea and diarrhoea and once-weekly exenatide the lowest risk of vomiting.. The RCTs in the present analysis show that all GLP-1RAs improve glycaemic control, reduce body weight and increase the risk of adverse gastrointestinal symptoms compared with placebo. Although there were no differences when short-acting agents were compared with each other or when long-acting agents were compared with each other, dulaglutide, liraglutide and once-weekly exenatide were superior to twice-daily exenatide and lixisenatide at lowering HbA1c and FPG levels. There were no differences in hypoglycaemia between these 3 agents, whilst once-weekly exenatide had the lowest risk of vomiting. These results, along with patient's preferences and individualized targets, should be considered when selecting a GLP-1RA.

The Role of the Pharmacist in Managing Type 2 Diabetes with Glucagon-Like Peptide-1 Receptor Agonists as Add-On Therapy.
The prevalence and associated clinical burden of type 2 diabetes (T2D) is increasing in the USA and other countries. As a consequence, the role of the pharmacist in managing T2D is expanding, and it is becoming increasingly important for pharmacists to have a complete understanding of the disease course and treatment options. Pharmacists have a key role in the use of injectable therapies, including incretin-based treatment with glucagon-like peptide-1 receptor agonists (GLP-1RAs). This article discusses the role of the pharmacist in the management of patients with T2D, particularly with respect to the use of GLP-1RAs to achieve glycemic control. GLP-1RAs are a class of injectable agents used as an adjunct to diet and exercise to improve glycemic control in adults with T2D. GLP-1RAs have been shown to lower glucose levels, slow gastric emptying, enhance satiety, and reduce body weight without increasing the risk of hypoglycemia. GLP-1RAs currently approved in the USA include exenatide twice daily, liraglutide once daily, and albiglutide, dulaglutide, and exenatide once weekly. Pharmacists can work with physicians to help identify patients for whom GLP-1RA therapy is appropriate. In addition, pharmacists can educate patients regarding medication storage, preparation, and injection techniques, glycated hemoglobin (HbA. AstraZeneca.

Short-acting glucagon-like peptide-1 receptor agonists as add-on to insulin therapy in type 1 diabetes: A review.
A large proportion of patients with type 1 diabetes do not reach their glycaemic target of glycated hemoglobin (HbA1c) <7.0% (53 mmol/mol) and, furthermore, an increasing number of patients with type 1 diabetes are overweight and obese. Treatment of type 1 diabetes is based on insulin therapy, which is associated with well-described and unfortunate adverse effects such as hypoglycaemia and increased body weight. Glucagon-like peptide-1 (GLP-1) receptor agonists (RAs) are the focus of increasing interest as a possible adjunctive treatment to insulin in type 1 diabetes because of their glucagonostatic and extrapancreatic effects. So far, the focus has mainly been on the long-acting GLP-1RAs, but the risk-benefit ratio emerging from studies evaluating the effect of long-acting GLP-1RAs as adjunctive therapy to insulin therapy in patients with type 1 diabetes has been disappointing. This might be attributable to a lack of glucagonostatic effect of these long-acting GLP-1RAs in type 1 diabetes, alongside development of tachyphylaxis to GLP-1-induced retardation of gastric emptying. In contrast, the short-acting GLP-1RAs seem to have a preserved and sustained effect on glucagon secretion and gastric emptying in patients with type 1 diabetes, which could translate into effective lowering of postprandial glucose excursions; however, these observations regarding short-acting GLP-1RAs are all derived from small open-label trials and should thus be interpreted with caution. In the present paper we review the potential role of GLP-1RAs, in particular short-acting GLP-1RAs, as add-on to insulin in the treatment of type 1 diabetes.

Achieving the composite endpoint of glycated haemoglobin <7.0%, no weight gain and no hypoglycaemia in the once-weekly dulaglutide AWARD programme.
To compare the effectiveness of dulaglutide 1.5 and 0.75 mg with active comparators and placebo with regard to a composite endpoint of glycated haemoglobin (HbA1c), weight and hypoglycaemia, using post hoc analyses.. A logistic regression analysis was performed on the intention-to-treat population, using data from the last observation carried forward, and the composite endpoint of HbA1c <7.0% (53 mmol/mol), no weight gain (≤0 kg) and no hypoglycaemia (glucose <3.0 mmol/l or severe hypoglycaemia) after 26 weeks for each trial in the AWARD programme separately.. At 26 weeks, within each study, 37-58% of patients on dulaglutide 1.5 mg, 27-49% of patients on dulaglutide 0.75 mg, and 9-61% of patients on active comparators achieved the composite endpoint. Significantly more patients reached the composite endpoint with dulaglutide 1.5 mg than with metformin, sitagliptin, exenatide twice daily or insulin glargine: odds ratio (OR) 1.5 [95% confidence interval (CI) 1.0, 2.2; p < 0.05], OR 4.5 (95% CI 3.0, 6.6; p < 0.001), OR 2.6 (95% CI 1.8, 3.7; p < 0.001) and OR 7.4 (95% CI 4.4, 12.6; p < 0.001), respectively, with no difference between dulaglutide 1.5 mg and liraglutide 1.8 mg. In addition, significantly more patients reached the composite endpoint with dulaglutide 0.75 mg than with sitagliptin or insulin glargine: OR 3.3 (95% CI 2.2, 4.8; p < 0.001) and OR 4.5 (95% CI 2.7, 7.8; p < 0.001), respectively.. Dulaglutide is an effective treatment option, resulting in a similar or greater proportion of patients reaching the HbA1c target of <7.0% (53 mmol/mol), without weight gain or hypoglycaemia compared with active comparators.

Efficacy and safety of dulaglutide in patients with type 2 diabetes: a meta-analysis and systematic review.
A meta-analysis was conducted to assess the clinical efficacy and safety of dulaglutide in patients with type 2 diabetes mellitus (T2DM). Medline, Embase, Cochrane Library and www. clinicaltrials. gov (up to February 15(th), 2015) were searched. Randomized controlled trials comparing dulaglutide to other drugs for T2DM were collected. Twelve RCTs were included, and the overall bias was low. As the monotherapy, compared with control (placebo, metformin and liraglutide), dulaglutide resulted in a significant reduction in HbA1c (WMD, -0.68%; 95% CI, -0.95 to -0.40), FPG (WMD, -0.90 mmol/L; 95% CI, -1.28 to -0.52), a similar risk of hypoglycemia (7.8% vs. 10.6%), less body weight loss (WMD, 0.51 kg; 95% CI, 0.27 to 0.75). As an add-on intervention with oral antihyperglycemic medication (OAM) and insulin, compared with control (placebo, sitagliptin, exenatide, liraglutide and glargine), dulaglutide lowered HbA1c (WMD, -0.51%; 95% CI, -0.68 to -0.35) and body weight significantly (WMD, -1.30 kg, 95% CI, -1.85 to -1.02) notably, and elicited a similar reduction in FPG (WMD, -0.19 mmol/L; 95% CI, -1.20 to 0.82), an similar incidence of hypoglycemia (24.5% vs. 24.5%). This meta-analysis revealed the use of dulaglutide as a monotherapy or an add-on to OAM and lispro appeared to be effective and safe for adults with T2DM.

GLP-1 Agonists in Type 1 Diabetes Mellitus.
To review the use of GLP-1 agonists in patients with type 1 diabetes mellitus (T1DM).. A search using the MEDLINE database, EMBASE, and Cochrane Database was performed through March 2016 using the search terms glucagon-like peptide 1 (GLP-1) agonists, incretin, liraglutide, exenatide, albiglutide, dulaglutide, type 1 diabetes mellitus. All English-language trials that examined glycemic end points using GLP-1 agonists in humans with T1DM were included.. A total of 9 clinical trials examining the use of GLP-1 agonists in T1DM were identified. On average, hemoglobin A1C (A1C) was lower than baseline, with a maximal lowering of 0.6%. This effect was not significant when tested against a control group, with a relative decrease in A1C of 0.1% to 0.2%. In all trials examined, reported hypoglycemia was low, demonstrating no difference when compared with insulin monotherapy. Weight loss was seen in all trials, with a maximum weight loss of 6.4 kg over 24 weeks. Gastrointestinal adverse effects are potentially limiting, with a significant number of patients in trials reporting nausea.. The use of GLP-1 agonists should be considered in T1DM patients who are overweight or obese and not at glycemic goals despite aggressive insulin therapy; however, tolerability of these agents is a potential concern. Liraglutide has the strongest evidence for use and would be the agent of choice for use in overweight or obese adult patients with uncontrolled T1DM.

Efficacy and safety of once-weekly glucagon-like peptide-1 receptor agonists compared with exenatide and liraglutide in type 2 diabetes: a systemic review of randomised controlled trials.
Once-weekly glucagon-like peptide-1 receptor agonists (GLP-1RAs) have shown promising results in the treatment of type 2 diabetes. Herein, we compared the efficacy and safety of once-weekly GLP-1RAs with exenatide and liraglutide separately.. We systematically surveyed the pertinent literature using various databases. The randomised controlled trials that compared once-weekly GLP-1RAs with exenatide and liraglutide in type 2 diabetes were included. Our main end-points were control of glycaemia, body weight, hypoglycaemia and gastrointestinal adverse events (AEs).. Our analysis included eight trials involving 5531 patients. Exenatide-long-acting release (LAR), dulaglutide and taspoglutide were more effective than twice-daily exenatide in reducing glycosylated haemoglobin A1c (HbA1c) and fasting blood glucose (FBG) levels and achieving HbA1c targets (< 7.0% and ≤ 6.5%). Liraglutide was as effective as dulaglutide and more effective than exenatide-LAR and albiglutide in controlling glycaemia. With regard to the effectiveness in decreasing body weight, exenatide-LAR, dulaglutide and taspoglutide were similar to exenatide whereas exenatide-LAR, dulaglutide and albiglutide were inferior to liraglutide. Once-weekly GLP-1RAs, exenatide and liraglutide resulted in a similar incidence of hypoglycaemia and of gastrointestinal, serious, or other AEs.. Once-weekly GLP-1RAs were more effective in controlling glycaemia and equally effective in decreasing body weight than twice-daily exenatide but were inferior to liraglutide in controlling these two parameters (dulaglutide was similar with liraglutide in controlling glycaemia). Once-weekly GLP-1RAs, exenatide and liraglutide had a similar risk of causing AEs.

Effectiveness and Safety of Newer Antidiabetic Medications for Ramadan Fasting Diabetic Patients.
Hypoglycemia is the most common side effects for most glucose-lowering therapies. It constitutes a serious risk that faces diabetic patients who fast during Ramadan (the 9th month in the Islamic calendar). New glucose-lowering classes like dipeptidyl peptidase-4 (DPP-4) inhibitors, glucagon-like peptide 1 receptor agonist (GLP-1 RA), and sodium-glucose cotransporter-2 (SGLT-2) inhibitors are efficacious in controlling blood glucose level with less tendency to induce hypoglycemia and thus may constitute a good choice for diabetic patients during Ramadan. This study reviews the safety and efficacy of newer glucose-lowering therapies during Ramadan. This study was accomplished through a careful literature search about studies that assess the benefit and side effects of these new glucose-lowering therapies during Ramadan during September 2015. Vildagliptin, sitagliptin, liraglutide, exenatide, and dapagliflozin were the only studied glucose-lowering therapies. All of the studied newer glucose-lowering therapies except dapagliflozin were associated with reduced risk to induce hypoglycemia. Gastrointestinal upset was common with the usage of liraglutide while increased thirst sensation was common with dapagliflozin. In conclusion DPP-4 inhibitors such as vildagliptin and sitagliptin may form a suitable glucose-lowering therapy option for Ramadan fasting patients.

Emerging new therapies for the treatment of type 2 diabetes mellitus: glucagon-like peptide-1 receptor agonists.
The goal of this article was to review the safety, efficacy, and potential for utilization of the newly approved once-weekly glucagon-like peptide-1 (GLP-1) receptor agonists in the treatment of type 2 diabetes.. Published articles for Phase III trials were found by performing a MEDLINE search using the search terms exenatide, exenatide once weekly, DURATION, albiglutide, and HARMONY as key terms. Search results were restricted by using filters to include clinical trials in humans. A search of relevant diabetes journals (including Diabetes Care and Diabetologia) was also performed to find abstracts for studies that did not have complete published articles at the time of this review.. Exenatide once weekly reduced glycosylated hemoglobin (HbA1c) by -1.0% to -2.0% when used as monotherapy and add-on therapy; it also provided significant weight loss ranging from 2 to 4 kg and maintained a relatively low risk of hypoglycemia. Albiglutide was able to reduce glycosylated hemoglobin levels between -0.5% and -0.84% when used as monotherapy and in combination with other antidiabetic medications. The newest once-weekly GLP-1 receptor agonist, dulaglutide, reduced glycosylated hemoglobin levels between -0.78% and -1.51% and demonstrated noninferiority to once-daily liraglutide.. The GLP-1 receptor agonists have proven efficacy in the treatment of type 2 diabetes and may provide patients with additional nonglycemic benefits, including significant weight loss and decreased systolic blood pressure. The newer once-weekly formulations are more convenient than the BID and once-daily medications, which could improve adherence and may be more attractive to providers and patients.

Once-weekly exenatide as a treatment for Type 2 diabetes.
Type 2 diabetes mellitus is a progressive disease that requires pharmacologic treatment to prevent microvascular and macrovascular complications. As the disease progresses, most patients require combination therapy to achieve glucose control targets. Exenatide once weekly (EQW) is a glucagon-like peptide-1 receptor agonist approved in the United States in 2012 for use as a second-line agent to treat Type 2 diabetes mellitus. EQW has shown reductions in HbA1c and weight without causing an increased risk of hypoglycemia. This review will summarize the current clinical trial, observational study, and pharmacoeconomic analyses evaluating EQW and its impact on HbA1c and weight.

Options for prandial glucose management in type 2 diabetes patients using basal insulin: addition of a short-acting GLP-1 analogue versus progression to basal-bolus therapy.
Integrating patient-centered diabetes care and algorithmic medicine poses particular challenges when optimized basal insulin fails to maintain glycaemic control in patients with type 2 diabetes. Multiple entwined physiological, psychosocial and systems barriers to insulin adherence are not easily studied and are not adequately considered in most treatment algorithms. Moreover, the limited number of alternatives to add-on prandial insulin therapy has hindered shared decision-making, a central feature of patient-centered care. This article considers how the addition of a glucagon-like peptide 1 (GLP-1) analogue to basal insulin may provide new opportunities at this stage of treatment, especially for patients concerned about weight gain and risk of hypoglycaemia. A flexible framework for patient-clinician discussions is presented to encourage development of decision-support tools applicable to both specialty and primary care practice.

[Twice-daily and weekly exenatide: clinical profile of two pioneer formulations in incretin therapy].
GLP-1 receptors agonists have been a substantial change in treatment of type 2 diabetes mellitus, and its weekly administration has broken pre-established schemes. Daily exenatide is administered every 12 hours (BID) subcutaneously, while weekly exenatide is administered once a week. Both molecules share a common mechanism of action but have differential effects on basal and postprandial glucose. We review the major clinical trials with both exenatide BID and weekly exenatide. It can be concluded that exenatide BID shows a hypoglycemic effect similar to other treatments for type 2 DM but adding significant weight loss with low incidence of hypoglycemia. Weekly exenatide decreases HbA1c similar to liraglutide but larger than exenatide BID, both glargine and biphasic insulin, sitagliptin, and pioglitazone, maintaining weight loss and adding to gastrointestinal intolerance the induration at the injection site as a side effect.

GLP-1R agonist therapy for diabetes: benefits and potential risks.
Glucagon-like peptide 1 receptor (GLP-1R) agonists provide good glycemic control combined with low hypoglycemia risk and weight loss. Here, we summarize the recently published data for this therapy class, focusing on sustainability of action, use in combination with basal insulin, and the efficacy of longer acting agents currently in development. The safety profile of GLP-1R agonists is also examined.. GLP-1R agonists provide sustained efficacy and their combination with basal insulin is well tolerated, providing additional glycemic control and weight benefits compared with basal insulin alone. Data suggest that the convenience of longer acting agents may be at the expense of efficacy. Despite the initial concerns, most evidence indicates that GLP-1R agonists do not increase the risk of pancreatitis or thyroid cancer. However, the extremely low incidence of these events means further investigations are required before a causal link can be eliminated. Large-scale clinical trials investigating the long-term cardiovascular safety of this therapy class are ongoing and may also provide important insights into pancreatic and thyroid safety.. GLP-1R agonists offer sustained glycemic efficacy, weight loss benefits, and a low risk of hypoglycemia. The results of ongoing trials should help to clarify the safety of this therapy class.

[GLP-1 agonists: an overview].
GLP-1 agonists have been widely used in the therapy of type 2 diabetes due to their beneficial effects regarding weight loss and low risk of hypoglycemia. However, some safety concerns have been raised in view of possible detrimental effects to the pancreas. The future place of GLP-1 agonist in diabetes therapy will be determined by the current safety evaluation and data from studies investigating long-term effects.

Type 1 diabetes and cardiovascular disease.
The presence of cardiovascular disease (CVD) in Type 1 diabetes largely impairs life expectancy. Hyperglycemia leading to an increase in oxidative stress is considered to be the key pathophysiological factor of both micro- and macrovascular complications. In Type 1 diabetes, the presence of coronary calcifications is also related to coronary artery disease. Cardiac autonomic neuropathy, which significantly impairs myocardial function and blood flow, also enhances cardiac abnormalities. Also hypoglycemic episodes are considered to adversely influence cardiac performance. Intensive insulin therapy has been demonstrated to reduce the occurrence and progression of both micro- and macrovascular complications. This has been evidenced by the Diabetes Control and Complications Trial (DCCT) / Epidemiology of Diabetes Interventions and Complications (EDIC) study. The concept of a metabolic memory emerged based on the results of the study, which established that intensified insulin therapy is the standard of treatment of Type 1 diabetes. Future therapies may also include glucagon-like peptide (GLP)-based treatment therapies. Pilot studies with GLP-1-analogues have been shown to reduce insulin requirements.

Combination therapy with GLP-1 receptor agonists and basal insulin: a systematic review of the literature.
Treatment algorithms for type 2 diabetes call for intensification of therapy over time as the disease progresses and glycaemic control worsens. If diet, exercise and oral antihyperglycaemic medications (OAMs) fail to maintain glycaemic control then basal insulin is added and ultimately prandial insulin may be required. However, such an intensification strategy carries risk of increased hypoglycaemia and weight gain, both of which are associated with worse long-term outcomes. An alternative strategy is to intensify therapy by the addition of a short-acting glucagon-like peptide-1 receptor agonist (GLP-1 RA) rather than prandial insulin. Short-acting GLP-1 RAs such as exenatide twice daily are particularly effective at reducing postprandial glucose while basal insulin has a greater effect on fasting glucose, providing a physiological rationale for this complementary approach. This review analyzes the latest randomized controlled clinical trials of insulin/GLP-1 RA combination therapy and examines results from 'real-world' use of the combinations as reported through observational and clinical practice studies. The most common finding across all types of studies was that combination therapy improved glycaemic control without weight gain or an increased risk of hypoglycaemia. Many studies reported weight loss and a reduction in insulin use when a GLP-1 RA was added to existing insulin therapy. Overall, the relative degree of benefit to glycaemic control and weight was influenced by the insulin titration employed in conjunction with the GLP-1 RA. The greatest glycaemic benefits were observed in studies with structured titration of insulin to glycaemic targets while the greatest weight benefits were observed in studies with a protocol-specified focus on insulin sparing. The adverse event profile of GLP-1 RAs in the reviewed trials was similar to that reported with GLP-1 RAs as monotherapy or in combination with OAMs with gastrointestinal events being the most commonly reported.

Current treatments and strategies for type 2 diabetes: can we do better with GLP-1 receptor agonists?
Abstract Diet, lifestyle modification, and pharmacotherapy with metformin are appropriate initial treatments for many patients with type 2 diabetes (T2DM). However, most individuals do not maintain glycemic control with metformin alone. Addition of other oral antidiabetes drugs (OADs), including sulfonylurea, meglitinide, or thiazolidinedione, is often the next step. Newer options, including incretin-based glucagon-like peptide-1 (GLP-1) receptor agonists (RAs) and dipeptidyl peptidase-4 (DPP-4) inhibitors, offer important benefits as monotherapies or in combination with OADs, with low risk for hypoglycemia. Reductions in glycated hemoglobin (A1C) have been reported among patients treated with GLP-1 RAs (exenatide, -0.8 to -1.1%; liraglutide, -0.8 to -1.6%), as has weight loss (exenatide, -1.6 to -3.1 kg; liraglutide, -1.6 to -3.2 kg). GLP-1 RAs also stimulate β-cell responses and have positive effects on cardiovascular risk factors often present in patients with T2DM. The most common adverse events associated with GLP-1 RAs are nausea, which diminishes over time, and hypoglycemia (when used in combination with a sulfonylurea). A large number of trials demonstrated benefits of GLP-1 RAs, suggesting they could provide suitable treatment options for patients with T2DM.

Drug-induced hypoglycaemia in type 2 diabetes.
Hypoglycaemia is a side effect caused by some therapies for type 2 diabetes, which can cause physical, social and psychological harm. Hypoglycaemia also prevents attainment of treatment goals and satisfactory glycaemic control.. The risk of hypoglycaemia associated with commonly prescribed therapies, including metformin, sulphonylureas, dipeptidyl peptidase-4 enzyme (DPP-4) inhibitors, glucagon-like peptide-1 (GLP-1) agonists and thiazolidinediones, is reviewed in this paper (insulin-induced hypoglycaemia is not included). Other medications that are frequently co-prescribed in type 2 diabetes are also discussed, including anti-hypertensive drugs, antibiotics and fibrates, along with various important patient-related risk factors.. Hypoglycaemia is a common and potentially dangerous side effect of some medications used for type 2 diabetes. The risk of hypoglycaemia should always be considered when selecting and implementing a therapy, with a focus on the individual. Future research into new therapies should measure the frequency of hypoglycaemia prospectively and accurately. Hypoglycaemia has been shown to be a potentially life-threatening metabolic stress; therefore therapies that effectively manage diabetes without the risk of hypoglycaemia are likely to be favoured in the future.

Comparison of safety and tolerability with continuous (exenatide once weekly) or intermittent (exenatide twice daily) GLP-1 receptor agonism in patients with type 2 diabetes.
Exenatide is a glucagon-like peptide-1 receptor agonist shown to improve glycaemic control in patients with type 2 diabetes (T2DM). Intermittent exenatide exposure is achieved with the twice-daily formulation (ExBID), while the once-weekly formulation (ExQW) provides continuous exenatide exposure. This integrated, retrospective analysis compared safety and tolerability of ExQW vs. ExBID in patients with T2DM.. Data were pooled from two open-label, randomized, comparator-controlled, trials directly comparing ExQW (N = 277) to ExBID (N = 268). Between-group differences in adverse event (AE) and hypoglycaemia incidences were calculated. Incidence over time and duration of selected AEs (nausea, vomiting, and injection-site-related AEs) were also summarized.. The most common AEs were nausea, diarrhoea, injection-site pruritus, and vomiting. Nausea and vomiting occurred less frequently with ExQW vs. ExBID, peaking at initiation (ExQW) or at initiation and dose escalation (ExBID), and decreasing over time. Few patients discontinued because of gastrointestinal-related AEs. Injection-site AEs were more common with ExQW but decreased over time in both groups. No major hypoglycaemia occurred; minor hypoglycaemia occurred with low incidence in patients not using concomitant sulphonylurea, with no difference between ExQW and ExBID. Serious AEs and discontinuations because of AEs were reported with similar frequency in both groups.. Both exenatide formulations were generally safe and well-tolerated, with ExQW associated with less nausea and vomiting but more injection-site AEs. Continuous vs. intermittent exposure did not impact the overall tolerability profile of exenatide, with no evidence of prolonged duration or worsened intensities of AEs with continuous exposure.

Exenatide once weekly for the treatment of type 2 diabetes: effectiveness and tolerability in patient subpopulations.
Patient numbers in individual diabetes trials are often too limited to assess the effect of a treatment by different patient characteristics, and meta-analyses often do not include patient-level data. The purpose of this pooled analysis was to evaluate the efficacy and tolerability of exenatide once weekly (EQW) in patients with type 2 diabetes grouped into subpopulations by key demographic characteristics.. This post hoc analysis included data from patients who received EQW in seven randomised, controlled phase 3 trials that were 24-30 weeks in duration. Patients were classified into subpopulations on the basis of their baseline age (< 65 or ≥ 65 years), gender (male or female), race (White, Black, Asian, Hispanic), duration of diabetes (< 10 years, ≥ 10 years) and body mass index (BMI; < 25, ≥ 25 to < 30, ≥ 30 to < 35, ≥ 35 to < 40 or ≥ 40 kg/m(2)).. A total of 1719 patients were included in this analysis of patient subpopulations. All subpopulations experienced significant improvements from baseline in haemoglobin A1C, fasting glucose and body weight. Most subpopulations experienced significant improvements in blood pressure and lipid parameters. Overall, the most common AEs were hypoglycaemia (16.4% overall; 2.3% in patients not on concomitant sulfonylurea), nausea (14.7%), diarrhoea (10.9%) and nasopharyngitis (7.2%).. These results show that the treatment of type 2 diabetes with EQW for 24-30 weeks was associated with significant improvements in glycaemic control and body weight, irrespective of age, gender, race, duration of diabetes or BMI. The most common adverse events were gastrointestinal in nature.

The safety and tolerability of GLP-1 receptor agonists in the treatment of type 2 diabetes: a review.
Although several classes of pharmacotherapy are available for type 2 diabetes, glycaemic control is often hampered by medication-related adverse effects and contraindications such as renal impairment. Glucagon-like peptide-1 (GLP-1) receptor agonists provide a new pharmacotherapeutic option based on the multiple glucose-lowering effects of the human hormone GLP-1. This mechanism of action not only provides therapeutic efficacy but also suggests that GLP-1 receptor agonists have distinct safety and tolerability concerns compared with other diabetes therapies. Stimulation of pancreatic insulin secretion by GLP-1 receptor agonists is glucose dependent, conferring a lesser risk of hypoglycaemia than that seen with sulfonylureas. Individual GLP-1 receptor agonists differ in their metabolism and excretion profiles, affecting the choice of agent for patients with renal impairment. As with other protein-based therapies, GLP-1 receptor agonists may induce the formation of antibodies that may attenuate therapeutic efficacy and affect safety. Conclusions on cardiovascular safety must await outcomes studies, but at present no signal of harm has been reported, and preclinical data and effects on risk markers suggest a potential for benefit. Current data on thyroid medullary cancer in humans and pancreatic malignancy in rodents do not suggest that there is any reason to restrict the clinical use of GLP-1 analogues in most people with diabetes. It is currently difficult to ascertain the possible contributory role of GLP-1 receptor agonists in increasing the risk of pancreatitis, and vigilance for signs and symptoms is prudent. Primary tolerability issues include transient gastrointestinal symptoms, common with GLP-1 receptor agonists, which can be reduced through dose titration.

A meta-analysis of placebo-controlled clinical trials assessing the efficacy and safety of incretin-based medications in patients with type 2 diabetes.
A systematic review of the literature, in combination with a meta-analysis of randomized controlled trials comparing treatments with placebo, was conducted to provide an update on the clinical efficacy and safety of incretin-based medications in adult patients with type 2 diabetes.. A literature search (2000-2009) identified 38 placebo-controlled trials (phase II or later - parallel design) comparing exenatide (n = 8), liraglutide (n = 7), vildagliptin (n = 11) and sitagliptin (n = 12) with placebo. Outcomes were change from baseline in HbA(1c) and in weight, and the number of patient-reported hypoglycemic episodes. HbA(1c) and weight outcomes were analyzed as weighted mean differences (WMD), and the number of hypoglycemic episodes as relative risks (RR).. Patients receiving liraglutide showed greater reduction in HbA(1c) in comparison to placebo (WMD = -1.03, 95% confidence interval, CI = -1.16 to -0.90, p < 0.001) than those on sitagliptin (WMD = -0.79, 95% CI = -0.93 to -0.65, p < 0.001), exenatide (WMD = -0.75, 95% CI = -0.83 to -0.67, p < 0.001) or vildagliptin (WMD = -0.67, 95% CI = -0.83 to -0.52, p < 0.001). Weight was statistically significantly negatively associated with exenatide (WMD = -1.10, 95% CI = -1.32 to -0.87, p < 0.001) and positively associated with sitagliptin (WMD = 0.60, 95% CI = 0.33-0.87, p < 0.001) and vildagliptin (WMD = 0.56, 95% CI = 0.27-0.84, p < 0.001). The number of patient-reported hypoglycemic episodes was statistically significantly associated with the use of sitagliptin (RR = 2.56, 95% CI = 1.23-5.33, p = 0.01) and exenatide (RR = 2.40, 95% CI = 1.30-4.11, p = 0.002).. Incretin-based therapies are effective in glycemic control and also offer other advantages such as weight loss (exenatide and liraglutide). This may have an important impact on patient adherence to medication.

Advances in therapy for type 2 diabetes: GLP-1 receptor agonists and DPP-4 inhibitors.
Type 2 diabetes mellitus (T2DM) is intrinsically connected to overweight and obesity. It is a complex metabolic disorder that predisposes patients to, and is associated with, cardiovascular disease. In addition to the triumvirate of core defects associated with T2DM (involvement of the pancreatic beta cell, the muscle, and the liver), other mechanisms including hyperglucagonemia, accelerated gastric emptying, and incretin deficiency/resistance are also involved. This has led to the development of incretinbased therapies, such as glucagon-like peptide-1 (GLP-1) receptor agonists and dipeptidyl peptidase-4 (DPP-4) inhibitors. These newer therapies have beneficial effects on glycosylated hemoglobin A1c (HbA1c) levels, weight, and pancreatic beta-cell function.

Incretin-based therapies: a new potential treatment approach to overcome clinical inertia in type 2 diabetes.
Maintaining an adequate metabolic control is still a challenge in many patients with type 2 diabetes. Among the many factors advocated to explain the failure to achieve recommended goals, clinical inertia is increasingly recognised as a primary cause of poor glycaemic control. The existence of a "metabolic memory" strongly supports the adoption of a more aggressive treat-to-target approach, instead of waiting for treatment failure. This approach may be particularly important in the initial phases of the disease, to slow the progressive decline of beta-cell function and improve overall outcomes. The fear of hypoglycaemia and weight gain associated with most of the available treatments are among the main causes of clinical inertia, and strongly affect the attitudes of providers and patients toward therapy intensification. The incretin-based therapies represent a new potential goal-oriented treatment approach. Two classes of incretin-based drugs have been developed: GLP-1 mimetics (exenatide and liraglutide) and DPP-IV inhibitors (sitagliptin and vildagliptin). Incretino-mimetics have a peculiar mechanism of action that is associated with lack of hypoglycaemia and weight loss or neutrality; these characteristics may facilitate therapy intensification and help to attain established goals. Furthermore, they can induce benefits in terms of post-prandial hyperglicemia control and beta-cell function preservation. An early use of this class of drugs may show a positive impact on the disease progression and a delay in the need of insulin injections.

Incretin mimetics and dipeptidyl peptidase 4 inhibitors in clinical trials for the treatment of type 2 diabetes.
Exenatide is an incretin mimetic, while sitagliptin and vildagliptin are incretin enhancers used as adjunctive therapy in patients with type 2 diabetes failing oral agents. Sitagliptin and vildagliptin can also be used as monotherapy in patients with type 2 diabetes uncontrolled by diet.. To provide a critical review of clinical trials of exenatide, sitagliptin and vildagliptin.. Review of Phase III clinical trials based on Medline search published up to April 2008.. The use of exenatide is associated with reduction in average hemoglobin A1c (HbA1c) levels of approximately 0.8% compared with baseline. The corresponding reduction with either sitagliptin or vildagliptin is 0.7%. The actions of incretin-based drugs predominantly target postprandial hyperglycemia. Treatment-related hypoglycemia is generally mild, and mainly occurs when used with sulfonylureas (SUs). Exenatide treatment leads to a mild weight loss of around 2 kg after 30 weeks, whereas sitagliptin and vildagliptin have generally neutral effect on weight. Sitagliptin and vildagliptin are well tolerated in trials lasting up to 52 weeks. Meanwhile, 5 - 10% of patients cannot tolerate exenatide due to adverse effects, mainly nausea and vomiting. The three drugs are limited by the lack of long-term safety and efficacy data, as well as by their high cost.. Exenatide, sitagliptin and vildagliptin are useful add-on therapy for type 2 diabetes that is suboptimally controlled on oral agents, particularly when there is concern about weight gain and hypoglycemia, or when postprandial hyperglycemia is the major cause of inadequate glycemic control. Sitagliptin and vildagliptin may be used as monotherapy in patients who cannot tolerate metformin or SU, and sitagliptin may be used as alternative to metformin in renal insufficiency.

Management of Poststroke Hyperglycemia: Results of the TEXAIS Randomized Clinical Trial.
Hyperglycemia in acute ischemic stroke reduces the efficacy of stroke thrombolysis and thrombectomy, with worse clinical outcomes. Insulin-based therapies are difficult to implement and may cause hypoglycemia. We investigated whether exenatide, a GLP-1 (glucagon-like peptide-1) receptor agonist, would improve stroke outcomes, and control poststroke hyperglycemia with minimal hypoglycemia.. The TEXAIS trial (Treatment With Exenatide in Acute Ischemic Stroke) was an international, multicenter, phase 2 prospective randomized clinical trial (PROBE [Prospective Randomized Open Blinded End-Point] design) enrolling adult patients with acute ischemic stroke ≤9 hours of stroke onset to receive exenatide (5 µg BID subcutaneous injection) or standard care for 5 days, or until hospital discharge (whichever sooner). The primary outcome (intention to treat) was the proportion of patients with ≥8-point improvement in National Institutes of Health Stroke Scale score (or National Institutes of Health Stroke Scale scores 0-1) at 7 days poststroke. Safety outcomes included death, episodes of hyperglycemia, hypoglycemia, and adverse event.. From April 2016 to June 2021, 350 patients were randomized (exenatide, n=177, standard care, n=173). Median age, 71 years (interquartile range, 62-79), median National Institutes of Health Stroke Scale score, 4 (interquartile range, 2-8). Planned recruitment (n=528) was stopped early due to COVID-19 disruptions and funding constraints. The primary outcome was achieved in 97 of 171 (56.7%) in the standard care group versus 104 of 170 (61.2%) in the exenatide group (adjusted odds ratio, 1.22 [95% CI, 0.79-1.88];. Treatment with exenatide did not reduce neurological impairment at 7 days in patients with acute ischemic stroke. Exenatide did significantly reduce the frequency of hyperglycemic events, without hypoglycemia, and was safe to use. Larger acute stroke trials using GLP-1 agonists such as exenatide should be considered.. URL: www.australianclinicaltrials.gov.au; Unique identifier: ACTRN12617000409370.

Efficacy and safety of once-weekly exenatide after switching from twice-daily exenatide in patients with type 2 diabetes.
To evaluate the efficacy and safety of once-weekly (q.w.) extended-release exenatide after switching from twice-daily (b.i.d.) exenatide in patients with type 2 diabetes.. This was an investigator-initiated, prospective, single-arm, multicenter study. Individuals with type 2 diabetes who had been treated with exenatide b.i.d. for at least 3 months were enrolled and switched to exenatide q.w. for 24 weeks. The primary end-point was change in HbA1c at week 24 to test the glucose-lowering effect of exenatide q.w. versus exenatide b.i.d.. A total of 58 Japanese individuals with type 2 diabetes completed the study. Glycated hemoglobin was reduced by 0.2% at week 24 (7.2 ± 1.2% vs 7.0 ± 1.2% [56 ± 13 vs 53 ± 13 mmol/mol], 95% confidence interval -0.4 to -0.03%, P < 0.005 for non-inferiority, P = 0.01 for superiority). Fasting plasma glucose was reduced by 12 mg/dL at week 24 (154 ± 46 vs 142 ± 46 mg/dL, P = 0.02). β-Cell function assessed by homeostasis model assessment of β-cell function and C-peptide index was significantly improved at week 24. The incidence of self-reported hypoglycemia was reduced, and treatment satisfaction assessed by the Diabetes Treatment Satisfaction Questionnaire and Diabetes Medication Satisfaction Questionnaire was improved at week 24, with no change in body weight. There was no serious adverse event related to the study drug.. Switching from exenatide b.i.d. to exenatide q.w. resulted in a reduction in glycated hemoglobin, fasting plasma glucose and the incidence of hypoglycemia, and improvement in β-cell function and treatment satisfaction in patients with type 2 diabetes. These findings will be useful for selecting optimal treatment in individuals with type 2 diabetes.

Confirming the Bidirectional Nature of the Association Between Severe Hypoglycemic and Cardiovascular Events in Type 2 Diabetes: Insights From EXSCEL.
We sought to confirm a bidirectional association between severe hypoglycemic events (SHEs) and cardiovascular (CV) event risk and to characterize individuals at dual risk.. In a post hoc analysis of 14,752 Exenatide Study of Cardiovascular Event Lowering (EXSCEL) participants, we examined time-dependent associations between SHEs and subsequent major adverse cardiac events (CV death, nonfatal myocardial infarction [MI] or stroke), fatal/nonfatal MI, fatal/nonfatal stroke, hospitalization for acute coronary syndrome (hACS), hospitalization for heart failure (hHF), and all-cause mortality (ACM), as well as time-dependent associations between nonfatal CV events and subsequent SHEs.. SHEs were uncommon and not associated with once-weekly exenatide therapy (hazard ratio 1.13 [95% CI 0.94-1.36],. These findings, showing greater risk of SHEs after CV events as well as greater risk of CV events after SHEs, validate a bidirectional relationship between CV events and SHEs in patients with high comorbidity scores.

Efficacy and safety of generic exenatide injection in Chinese patients with type 2 diabetes: a multicenter, randomized, controlled, non-inferiority trial.
This study aimed to compare the efficacy and safety of generic exenatide with branded exenatide Byetta. A multicenter, randomized, controlled, non-inferiority trial was performed. A total of 240 patients with T2DM and glycated hemoglobin (HbA1c) ≥ 7% (53 mmol/mol) to ≤ 9.0% (75 mmol/mol) on monotherapy or combination therapy of metformin and insulin secretagogues for at least 3 months were randomized into generic exenatide or branded exenatide groups with a 1:1 ratio for 16 weeks of treatment. The primary endpoint was the change in HbA1c levels from baseline at week 16, with a non-inferiority margin of - 0.35% (- 3.83 mmol/mol) (lower bound of one-sided 95% confidence interval (CI) > - 0.35% (- 3.83 mmol/mol)). Secondary endpoints included the proportion of participants achieving HbA1c < 7% (53 mmol/mol), the changes in fasting plasma glucose (FPG), 2-h postprandial glucose (2hPG) following a standard meal, 7-point self-monitoring blood glucose (SMBG) profiles, body weight change from baseline at week 16 and the change in HbA1c levels from baseline at week 8. Safety issues were also evaluated.. After 16 weeks of treatment, HbA1c levels decreased significantly from baseline in the two groups, with a reduction of - 1.10% ± 1.31% (- 12.0 mmol/mol ± 14.3 mmol/mol) in the generic exenatide group and - 1.08% ± 1.11% (- 11.8 mmol/mol ± 12.1 mmol/mol) in the branded exenatide group (both P < 0.001). The least-squares mean difference of HbA1c reduction between the two groups was - 0.03% (- 0.33 mmol/mol), with a lower one-sided 95% CI limit of - 0.27% (- 2.95 mmol/mol), which was higher than the prespecified non-inferiority margin of - 0.35% (- 3.83 mmol/mol). Moreover, there were no significant differences in the proportion of participants achieving HbA1c < 7% (53 mmol/mol) and the changes in FPG, 2hPG, 7-point SMBG profiles and body weight at week 16 and the change in HbA1c levels from baseline at week 8 (all P > 0.05) between the two groups. The incidence of adverse events, including the incidence of hypoglycemia (18.3% and 17.5%, respectively), was similar for the generic and branded exenatide groups (P > 0.05).. In patients with T2DM inadequately controlled on monotherapy or combination therapy of metformin and insulin secretagogues, add-on treatment with generic exenatide demonstrated non-inferiority to branded exenatide in terms of improvements in HbA1c after 16 weeks of treatment. Furthermore, the two drugs were also similar for other efficacy endpoints and safety profile. Trial registration Chinese Clinical Trial Registry: ChiCTR-IPR-15006558, Date registered May 27, 2015.

Efficacy and Safety Over 2 Years of Exenatide Plus Dapagliflozin in the DURATION-8 Study: A Multicenter, Double-Blind, Phase 3, Randomized Controlled Trial.
In patients with type 2 diabetes uncontrolled with metformin, exenatide once weekly (QW) plus dapagliflozin produced greater reductions in glycemic parameters (glycated hemoglobin [HbA. At week 104, 431 (62.0%) patients completed treatment. The adjusted least squares mean change (SE) from baseline to week 104 in HbA. In this exploratory analysis, among those individuals who completed the trial without rescue therapy, there was clinically relevant efficacy over 2 years with exenatide QW plus dapagliflozin, with no unexpected safety findings.

Exenatide and Renal Outcomes in Patients with Type 2 Diabetes and Diabetic Kidney Disease.
Cardiovascular outcomes in clinical trials with type 2 diabetes mellitus (T2DM) patients have shown that glucagon-like peptide-1 receptor agonist can have a beneficial effect on the kidney. This trial aimed to assess the effects of exenatide on renal outcomes in patients with T2DM and diabetic kidney disease (DKD).. We performed a randomized parallel study encompassing 4 general hospitals. T2DM patients with an estimated glomerular filtration rate (eGFR) ≥30 mL/min/1.73 m2 and macroalbuminuria, defined as 24-h urinary albumin excretion rate (UAER) >0.3 g/24 h were randomized 1:1 to receive exenatide twice daily plus insulin glargine (intervention group) or insulin lispro plus glargine (control group) for 24 weeks. The primary outcome was the UAER percentage change from the baseline after 24 weeks of intervention. The rates of hypoglycemia, adverse events (AEs), and change in eGFR during the follow-up were measured as safety outcomes.. Between March 2016 and April 2019, 92 patients were randomized and took at least 1 dose of the study drug. The mean age of the participants was 56 years. At baseline, the median UAER was 1,512.0 mg/24 h and mean eGFR was 70.4 mL/min/1.73 m2. After 24 weeks of treatment, the UAER percentage change was significantly lower in the intervention group than in the control group (p = 0.0255). Moreover, the body weight declined by 1.3 kg in the intervention group (the difference between the 2 groups was 2.7 kg, p = 0.0001). Compared to the control group, a lower frequency of hypoglycemia and more gastrointestinal AEs were observed in the intervention group.. Exenatide plus insulin glargine treatment for 24 weeks resulted in a reduction of albuminuria in T2DM patients with DKD.

Effects of GLP-1 on counter-regulatory responses during hypoglycemia after GBP surgery.
The aim of the study was to explore the role of GLP-1 receptor activation on the counter-regulation and symptoms of hypoglycemia in subjects who have undergone gastric bypass surgery (GBP).. Experimental hyperinsulinemic-hypoglycemic clamp study.. Twelve post-GBP subjects participated in a randomized cross-over study with two hyperinsulinemic, hypoglycemic clamps (glucose nadir 2.7 mmol/L) performed on separate days with concomitant infusions of the GLP-1 analog exenatide or with saline, respectively. Continuous measurements of metabolites and counter-regulatory hormones as well as assessments of heart rate variability and symptoms of hypoglycemia were performed throughout the clamps.. No effect of GLP-1 receptor activation on counter-regulatory hormones (glucagon, catecholamines, cortisol, GH) or glucose infusion rate was seen, but we found indications of a downregulation of the sympathetic relative to the parasympathetic nerve activity, as reflected in heart rate variability. No significant differences in symptom of hypoglycemia were observed.. Short-term exposure to a GLP-1 receptor agonist does not seem to impact the counter-regulatory hormonal and metabolic responses in post-GBP subjects during hypoglycemic conditions, suggesting that the improvement in symptomatic hypoglycemia post-GBP seen following treatment with GLP-1 receptor agonists may be mediated by mechanism not directly involved in counter-regulation.

Efficacy and tolerability of the new autoinjected suspension of exenatide once weekly versus exenatide twice daily in patients with type 2 diabetes.
To simplify administration of aqueous exenatide once weekly, which requires reconstitution, the exenatide microspheres have been reformulated in a ready-to-use autoinjector with a Miglyol diluent (exenatide QWS-AI). This study compared the efficacy and safety of exenatide QWS-AI with the first-in-class glucagon-like peptide-1 receptor agonist exenatide twice daily (BID).. This randomized, open-label, controlled study in patients with type 2 diabetes using diet and exercise or taking stable oral glucose-lowering medication randomized patients 3:2 to either exenatide QWS-AI (2 mg) or exenatide BID (10 μg) for 28 weeks. The primary outcome was the 28-week change in glycated haemoglobin (HbA1c). A subset of patients completed a standardized meal test for postprandial and pharmacokinetic assessments.. A total of 375 patients (mean HbA1c, 8.5% [69 mmol/mol]; body mass index, 33.2 kg/m. Exenatide QWS-AI was associated with a greater reduction in HbA1c, similar weight loss and a favorable gastrointestinal AE profile compared with exenatide BID.

The effects of add-on exenatide to insulin on glycemic variability and hypoglycemia in patients with type 1 diabetes mellitus.
To investigate the effect of add-on exenatide to insulin on glycemic excursion and the counter-regulatory hormone in response to hypoglycemia in patients with type 1 diabetes mellitus (T1DM).. 30 patients with T1DM were recruited and randomly assigned to exenatide + insulin-treated group (group 1, n = 15) or insulin-only-treated group (group 2, n = 15) for 4 weeks. All patients had continuous glucose monitor system (CGMS) applied at before (week-0) and after (week-4) treatment to evaluate the glycemic variability. All patients had an arginine-stimulated test at before and after treatment. Six patients from each group also had hypoglycemic clamp test to assess counter-regulatory hormone level.. Patients in the exenatide group had significant reductions in body weight, body mass index (BMI), total insulin dose, bolus insulin dose, fructosamine, and glycemic excursion after 4 weeks' treatment. Compared with patients in group 2, the mean amplitude of glycemic excursion (MAGE) and coefficient of variation (CV) of exenatide group decreased significantly. Similarly, a significant decrease of glucagon (GLC) in the arginine-stimulated test was found in group 1. No significant changes of GLC, growth hormone (GH), cortisol (COR), epinephrine (E), and norepinephrine (NE) were found in both groups during hypoglycemia clamp test. However, patients who had residual islet function in group 1 showed an upward trend of basic C-peptide (C-P) and GLC during the hypoglycemia period.. Although exenatide could inhibit glucagon secretion during euglycemia or hyperglycemia in patients with T1DM, it has no effect on GLC and counter-regulatory hormones during hypoglycemia clamp in patients with no functional residual islet test.

Effect of exenatide QW or placebo, both added to titrated insulin glargine, in uncontrolled type 2 diabetes: The DURATION-7 randomized study.
To compare the efficacy and safety of adding the glucagon-like peptide-1 receptor agonist exenatide once weekly (QW) 2 mg or placebo among patients with type 2 diabetes who were inadequately controlled despite titrated insulin glargine (IG) ± metformin.. This multicentre, double-blind study (ClinicalTrials.gov identifier: NCT02229383) randomized (1:1) patients with persistent hyperglycaemia after an 8-week titration phase (glycated haemoglobin [HbA1c] 7.0%-10.5% [53-91 mmol/mol]) to exenatide QW or placebo. The primary endpoint was HbA1c change from baseline to week 28. Secondary endpoints included body weight, 2-hour postprandial glucose, and mean daily IG dose.. Of 464 randomized patients (mean: age, 58 years; HbA1c, 8.5% [69 mmol/mol]; diabetes duration, 11.3 years), 91% completed 28 weeks. Exenatide QW + IG vs placebo + IG significantly reduced HbA1c (least-squares mean difference, -0.73% [-8.0 mmol/mol]; 95% confidence interval, -0.93%, -0.53% [-10.2, -5.8 mmol/mol]; P < .001; final HbA1c, 7.55% [59 mmol/mol] and 8.24% [67 mmol/mol], respectively); body weight (-1.50 kg; -2.17, -0.84; P < .001); and 2-hour postprandial glucose (-1.52 mmol/L [-27.5 mg/dL]; -2.15, -0.90 [-38.7, -16.2]; P < .001). Significantly more exenatide QW + IG-treated patients vs placebo + IG-treated patients reached HbA1c <7.0% (<53 mmol/mol) (32.5% vs 7.4%; P < .001); daily IG dose increased by 2 and 4 units, respectively. Gastrointestinal and injection-site adverse events were more frequent with exenatide QW + IG (15.1% and 7.8%, respectively) than with placebo + IG (10.8% and 3.0%, respectively); hypoglycaemia incidence was similar between the exenatide QW + IG (29.7%) and placebo + IG (29.0%) groups, with no major hypoglycaemic events.. Among patients with inadequate glycaemic control, exenatide QW significantly improved glucose control and decreased body weight, without increased hypoglycaemia or unexpected safety findings.

Semaglutide as a therapeutic option for elderly patients with type 2 diabetes: Pooled analysis of the SUSTAIN 1-5 trials.
The efficacy and safety of semaglutide vs comparators in non-elderly (<65 years) and elderly (≥65 years) patients with type 2 diabetes (T2D) across the SUSTAIN 1-5 trials were evaluated. Patients were randomized to once-weekly subcutaneous semaglutide (0.5 or 1.0 mg) vs placebo, sitagliptin, exenatide or insulin. The primary objective was change in HbA1c and secondary objectives were changes in body weight and safety. Mean HbA1c decreased from baseline by 1.2%-1.5% and 1.5%-1.9% vs 0%-0.9% (non-elderly, n = 3045) and by 1.3%-1.5% and 1.2%-1.8% vs 0.2%-1.0% (elderly, n = 854) with semaglutide 0.5 and 1.0 mg vs comparators. Similar reductions from baseline in mean body weight with semaglutide occurred in both age groups. Similar proportions of patients experienced adverse events; premature treatment discontinuations were higher in elderly vs non-elderly patients. No increased risk of severe or blood glucose-confirmed hypoglycaemia was seen with semaglutide vs comparators between age groups. Semaglutide had a comparable efficacy and safety profile in non-elderly and elderly patients across the SUSTAIN 1-5 trials, making it an effective treatment option for elderly patients with T2D.

Protocol for Meal-time Administration of Exenatide for Glycaemic Control in Type 1 Diabetes Cases (The MAG1C trial): a randomised, double-blinded, placebo-controlled trial.
Persons with type 1 diabetes require intensive insulin therapy to achieve glycaemic control, but side effects, including hypoglycaemia and weight gain, may reduce treatment compliance. We hypothesise that add-on treatment of the short-acting glucagon-like peptide-1 receptor agonist, exenatide, to insulin therapy in persons with type 1 diabetes will reduce insulin requirements, glycaemic excursions and body weight and improve glycaemic control without increasing the risk of hypoglycaemia. The present article describes a protocol developed to test this hypothesis.. One-hundred adult persons with type 1 diabetes for more than 1 year, insufficient glycaemic control (glycated haemoglobin A1c (HbA1c) between 58 and 86 mmol/mol) and body mass index >22.0 kg/m. The study is approved by the Danish Medicines Agency, the Regional Scientific Ethics Committee of the Capital Region of Denmark and the Data Protection Agency. The study will be carried out under the surveillance and guidance of the good clinical practice (GCP) unit at Copenhagen University Hospital Bispebjerg in accordance with the ICH-GCP guidelines and the Helsinki Declaration. Positive, negative as well as inconclusive results will be sought disseminated at scientific meetings and in international peer-reviewed scientific journals.. NCT03017352.

Effect of continuous exenatide infusion on cardiac function and peri-operative glucose control in patients undergoing cardiac surgery: A single-blind, randomized controlled trial.
We performed a randomized controlled trial with the glucagon-like peptide-1 (GLP-1) receptor agonist exenatide as add-on to standard peri-operative insulin therapy in patients undergoing elective cardiac surgery. The aims of the study were to intensify peri-operative glucose control while minimizing the risk of hypoglycaemia and to evaluate the suggested cardioprotective effects of GLP-1-based treatments. A total of 38 patients with decreased left ventricular systolic function (ejection fraction ≤50%) scheduled for elective coronary artery bypass grafting (CABG) were randomized to receive either exenatide or placebo in a continuous 72-hour intravenous (i.v.) infusion on top of standard peri-operative insulin therapy. While no significant difference in postoperative echocardiographic variables was found between the groups, participants receiving exenatide showed improved peri-operative glucose control as compared with the placebo group (average glycaemia 6.4 ± 0.5 vs 7.3 ± 0.8 mmol/L; P < .001; percentage of time in target range of 4.5-6.5 mmol/L 54.8% ± 14.5% vs 38.6% ± 14.4%; P = .001; percentage of time above target range 39.7% ± 13.9% vs 52.8% ± 15.2%; P = .009) without an increased risk of hypoglycaemia (glycaemia <3.3 mmol/L: 0.10 ± 0.32 vs 0.21 ± 0.42 episodes per participant; P = .586). Continuous administration of i.v. exenatide in patients undergoing elective CABG could provide a safe option for intensifying the peri-operative glucose management of such patients.

Upper and/or lower gastrointestinal adverse events with glucagon-like peptide-1 receptor agonists: Incidence and consequences.
To characterize gastrointestinal adverse events (AEs) with different glucagon-like peptide-1 receptor agonists (GLP-1RAs).. Two retrospective intention-to-treat analyses of 6-month patient-level data were conducted. Data from three studies comparing exenatide once weekly (n = 617) with exenatide twice daily (n = 606) were pooled, and one (DURATION-6) comparing exenatide once weekly (n = 461) with liraglutide (n = 450) was analysed separately. Patient-reported gastrointestinal AEs were classified as upper or lower, AE incidences and timing were determined, subgroups were analysed, and associations of gastrointestinal AEs with efficacy were examined.. Nausea was the most common gastrointestinal AE for all treatments. Fewer exenatide once-weekly-treated vs exenatide twice-daily- or liraglutide-treated patients reported gastrointestinal AEs (34% vs 45% and 25% vs 41%, respectively; both P < .0001). Fewer exenatide once-weekly-treated patients reported upper plus lower events than liraglutide-treated patients ( P < .001); the difference between exenatide once weekly and twice daily was not significant. Within each group, more women than men reported gastrointestinal AEs. Events occurrred early and were predominantly mild. Glycated haemoglobin reductions were similar for patients with or without gastrointestinal AEs. Weight loss was greater for patients with gastrointestinal AEs with exenatide once weekly and exenatide twice daily ( P < .05); no difference was observed in DURATION-6.. Gastrointestinal AEs were less frequent with exenatide once weekly vs exenatide twice daily or liraglutide, and combined upper and lower events occurred less often. Gastrointestinal AEs were typically mild and occurred early. Gastrointestinal AEs did not affect glycaemic control but may be associated with greater weight loss.

Glucose Variability in a 26-Week Randomized Comparison of Mealtime Treatment With Rapid-Acting Insulin Versus GLP-1 Agonist in Participants With Type 2 Diabetes at High Cardiovascular Risk.
A1C is associated with diabetes complications but does not reflect glycemic variability (GV), which may worsen outcomes by inducing inflammation, oxidative stress, and cardiac arrhythmias. We tested whether a glucagon-like peptide 1 agonist-based regimen can reduce GV and cardiometabolic risk markers while maintaining similar A1C levels in people with insulin-requiring type 2 diabetes and high cardiovascular risk.. After run-in on metformin and basal-bolus insulin (BBI), 102 participants continued metformin and basal insulin and were randomized to exenatide dosing before the two largest meals (glucacon-like peptide-1 receptor agonist and insulin [GLIPULIN group]) or continuation of rapid-acting insulin analogs (BBI group). Indices of GV by continuous glucose monitoring (CGM), hypoglycemia, weight, risk markers, and cardiac arrhythmias were assessed. The primary end point was change in glucose coefficients of variation (CV) by CGM from baseline to 26 weeks.. At randomization, the median A1C was 7.3% (57 mmol/mol) for GLIPULIN and 7.4% (56.3 mmol/mol) for BBI, and glucose CVs were 30.3 for BBI and 31.9 for GLIPULIN. At 26 weeks, A1C levels were similar (7.1% [54 mmol/mol] vs. 7.2% [55 mmol/mol]), whereas mean CV improved with GLIPULIN (-2.4 vs. 0.4, P = 0.047). Other GV indices followed similar nonsignificant patterns of improvement with GLIPULIN. There were no differences in hypoglycemic events during CGM or arrhythmias during electrocardiographic monitoring. On-trial changes in body weight (-4.8 kg vs. +0.7 kg, P < 0.001), alanine aminotransferase (P = 0.0002), and serum amyloid A (P = 0.023) favored GLIPULIN.. GLIPULIN reduced GV, weight, and some cardiometabolic risk markers while maintaining equivalent A1C levels versus BBI and might improve clinical outcomes in a larger trial.

The effects of exenatide twice daily compared to insulin lispro added to basal insulin in Latin American patients with type 2 diabetes: A retrospective analysis of the 4B trial.
Socioeconomic changes in Latin American countries have led to an increased prevalence of type 2 diabetes (T2D). We examined the effects of exenatide twice daily (BID) or insulin lispro, each added to insulin glargine, in Latin American patients with T2D.. This was a subgroup analysis of patients from Argentina and Mexico in the 4B study (N=114). Patients with glycated hemoglobin (HbA1c) of 7.0-10.0% (53-86mmol/mol) after 12weeks of intensive basal insulin optimization were randomized to exenatide BID or thrice-daily insulin lispro added to insulin glargine and metformin.. After 30weeks, addition of exenatide BID or insulin lispro resulted in significant (P<0.0001) reductions in HbA1c (exenatide BID: -0.9% [-10mmol/mol]; insulin lispro: -1.2% [-13mmol/mol]). Weight was stable in the exenatide BID group (-0.1kg) and increased significantly (+3.4kg; P<0.0001) with insulin lispro. Major and minor hypoglycemia occurred less frequently (40 vs. 253 events) with exenatide BID compared with insulin lispro. Gastrointestinal adverse events of nausea, diarrhea, and vomiting occurred more frequently with exenatide BID than with insulin lispro.. Both exenatide BID and prandial insulin lispro, each added to basal insulin glargine, were effective at reducing HbA1c in Latin American patients. Treatment with exenatide BID resulted in stable weight but more gastrointestinal adverse events. Treatment with insulin lispro resulted in weight gain and an increased risk of hypoglycemia.

Initial combination therapy with metformin, pioglitazone and exenatide is more effective than sequential add-on therapy in subjects with new-onset diabetes. Results from the Efficacy and Durability of Initial Combination Therapy for Type 2 Diabetes (EDICT
To test our hypothesis that initiating therapy with a combination of agents known to improve insulin secretion and insulin sensitivity in subjects with new-onset diabetes would produce greater, more durable reduction in glycated haemoglobin (HbA1c) levels, while avoiding hypoglycaemia and weight gain, compared with sequential addition of agents that lower plasma glucose but do not correct established pathophysiological abnormalities.. Drug-naïve, recently diagnosed subjects with type 2 diabetes mellitus (T2DM) were randomized in an open-fashion design in a single-centre study to metformin/pioglitazone/exenatide (triple therapy; n = 106) or an escalating dose of metformin followed by sequential addition of sulfonylurea and glargine insulin (conventional therapy; n = 115) to maintain HbA1c levels at <6.5% for 2 years.. Participants receiving triple therapy experienced a significantly greater reduction in HbA1c level than those receiving conventional therapy (5.95 vs. 6.50%; p < 0.001). Despite lower HbA1c values, participants receiving triple therapy experienced a 7.5-fold lower rate of hypoglycaemia compared with participants receiving conventional therapy. Participants receiving triple therapy experienced a mean weight loss of 1.2 kg versus a mean weight gain of 4.1 kg (p < 0.01) in those receiving conventional therapy.. The results of this exploratory study show that combination therapy with metformin/pioglitazone/exenatide in patients with newly diagnosed T2DM is more effective and results in fewer hypoglycaemic events than sequential add-on therapy with metformin, sulfonylurea and then basal insulin.

Treatment escalation options for patients with type 2 diabetes after failure of exenatide twice daily or glimepiride added to metformin: results from the prospective European Exenatide (EUREXA) study.
To evaluate third-line thiazolidinedione (TZD) or glimepiride therapy in patients inadequately controlled on metformin + exenatide twice daily, and third-line exenatide twice daily in patients inadequately controlled on metformin + glimepiride.. In this randomized, open-label, multicentre trial, 144 patients with type 2 diabetes inadequately controlled [glycated haemoglobin (HbA1c) >9% (75 mmol/mol) after 3 months' treatment or >7% (53 mmol/mol) at two consecutive visits 3 months apart, after 6 months' treatment] on metformin + exenatide twice daily were re-randomized to add-on TZD or glimepiride, and 166 patients inadequately controlled on metformin + glimepiride received add-on exenatide twice daily. Changes in HbA1c, body mass index (BMI), lipids, hypoglycaemia and vital signs were evaluated.. The median duration of triple therapy was ∼2 years. In patients inadequately controlled on metformin + exenatide twice daily, add-on TZD decreased HbA1c levels significantly better than add-on glimepiride: 130-week difference 0.48% [95% confidence interval (CI) 0.19-0.77] or 5.2 mmol/mol (95% CI 2.1-8.4; p = 0.001), but with significantly increased BMI and systolic blood pressure. The ratio of documented symptomatic (blood glucose ≤70 mg/dl [3.9 mmol/l]) hypoglycaemia rates for add-on glimepiride to add-on TZD was 8.48 (p < 0.0001). Add-on exenatide twice daily after metformin + glimepiride significantly reduced HbA1c levels: mean [standard deviation (s.d.)] change from baseline -0.35 (0.89)% [-3.8 (9.7) mmol/mol] and BMI: mean (s.d.) change from baseline -0.82 (1.9) kg/m(2) at 130 weeks, with a slightly increased rate of documented symptomatic hypoglycaemia from metformin + glimepiride (ratio 1.49).. TZD, but not glimepiride, was an effective and well tolerated third-line therapy in patients without glycaemic control after long-term therapy with metformin + exenatide twice daily. Exenatide twice daily was an effective and well tolerated third-line therapy in patients inadequately controlled on metformin + glimepiride.

Treatment satisfaction in people with type 2 diabetes mellitus treated with once-weekly dulaglutide: data from the AWARD-1 and AWARD-3 clinical trials.
To compare treatment satisfaction among people with type 2 diabetes receiving dulaglutide 1.5 mg and dulaglutide 0.75 mg (a once-weekly, long-acting, glucagon-like peptide-1 receptor agonist) with those receiving either exenatide or placebo (AWARD-1 study) or metformin (AWARD-3 study) over 52 weeks.. The Diabetes Treatment Satisfaction Questionnaire status version (DTSQs) and change version (DTSQc) were used to evaluate total treatment satisfaction and perceived frequency of hyperglycaemia and hypoglycaemia.. In the AWARD-1 study, significant improvements from baseline were observed in total DTSQs score for both dulaglutide doses (26 and 52 weeks) and exenatide (26 weeks). The improvement was significantly greater with both dulaglutide doses compared with placebo (26 weeks) and exenatide (26 and 52 weeks). The perceived frequency of hyperglycaemia was lower for all groups at 26 and 52 weeks compared with baseline. The improvement was greater with both dulaglutide doses and exenatide compared with placebo at 26 weeks, and was also greater with both dulaglutide doses compared with exenatide at 26 and 52 weeks. The exenatide group had an increase in perceived frequency of hypoglycaemia at 26 and 52 weeks. In the AWARD-3 study, significant improvements from baseline were observed for total DTSQs scores in all groups at 26 and 52 weeks. Perceived frequency of hyperglycaemia was lower for all groups at 26 and 52 weeks compared with baseline, and this improvement was greater with both dulaglutide doses compared with metformin at 52 weeks.. Dulaglutide was associated with improvements in treatment satisfaction and a decrease in perceived frequency of hyperglycaemia.

Efficacy and safety of dulaglutide added onto pioglitazone and metformin versus exenatide in type 2 diabetes in a randomized controlled trial (AWARD-1).
To compare the efficacy and safety of dulaglutide, a once-weekly GLP-1 receptor agonist, with placebo and exenatide in type 2 diabetic patients. The primary objective was to determine superiority of dulaglutide 1.5 mg versus placebo in HbA1c change at 26 weeks.. This 52-week, multicenter, parallel-arm study (primary end point: 26 weeks) randomized patients (2:2:2:1) to dulaglutide 1.5 mg, dulaglutide 0.75 mg, exenatide 10 μg, or placebo (placebo-controlled period: 26 weeks). Patients were treated with metformin (1,500-3,000 mg) and pioglitazone (30-45 mg). Mean baseline HbA1c was 8.1% (65 mmol/mol).. Least squares mean ± SE HbA1c change from baseline to the primary end point was -1.51 ± 0.06% (-16.5 ± 0.7 mmol/mol) for dulaglutide 1.5 mg, -1.30 ± 0.06% (-14.2 ± 0.7 mmol/mol) for dulaglutide 0.75 mg, -0.99 ± 0.06% (-10.8 ± 0.7 mmol/mol) for exenatide, and -0.46 ± 0.08% (-5.0 ± 0.9 mmol/mol) for placebo. Both dulaglutide doses were superior to placebo at 26 weeks (both adjusted one-sided P < 0.001) and exenatide at 26 and 52 weeks (both adjusted one-sided P < 0.001). Greater percentages of patients reached HbA1c targets with dulaglutide 1.5 mg and 0.75 mg than with placebo and exenatide (all P < 0.001). At 26 and 52 weeks, total hypoglycemia incidence was lower in patients receiving dulaglutide 1.5 mg than in those receiving exenatide; no dulaglutide-treated patients reported severe hypoglycemia. The most common gastrointestinal adverse events for dulaglutide were nausea, vomiting, and diarrhea. Events were mostly mild to moderate and transient.. Both once-weekly dulaglutide doses demonstrated superior glycemic control versus placebo and exenatide with an acceptable tolerability and safety profile.

Glucagon-like peptide 1 receptor agonist or bolus insulin with optimized basal insulin in type 2 diabetes.
Mealtime insulin is commonly added to manage hyperglycemia in type 2 diabetes when basal insulin is insufficient. However, this complex regimen is associated with weight gain and hypoglycemia. This study compared the efficacy and safety of exenatide twice daily or mealtime insulin lispro in patients inadequately controlled by insulin glargine and metformin despite up-titration.. In this 30-week, open-label, multicenter, randomized, noninferiority trial with 12 weeks prior insulin optimization, 627 patients with insufficient postoptimization glycated hemoglobin A1c (HbA1c) were randomized to exenatide (10-20 µg/day) or thrice-daily mealtime lispro titrated to premeal glucose of 5.6-6.0 mmol/L, both added to insulin glargine (mean 61 units/day at randomization) and metformin (mean 2,000 mg/day).. Randomization HbA1c and fasting glucose (FG) were 8.3% (67 mmol/mol) and 7.1 mmol/L for exenatide and 8.2% (66 mmol/mol) and 7.1 mmol/L for lispro. At 30 weeks postrandomization, mean HbA1c changes were noninferior for exenatide compared with lispro (-1.13 and -1.10%, respectively); treatment differences were -0.04 (95% CI -0.18, 0.11) in per-protocol (n = 510) and -0.03 (95% CI -0.16, 0.11) in intent-to-treat (n = 627) populations. FG was lower with exenatide than lispro (6.5 vs. 7.2 mmol/L; P = 0.002). Weight decreased with exenatide and increased with lispro (-2.5 vs. +2.1 kg; P < 0.001). More patients reported treatment satisfaction and better quality of life with exenatide than lispro, although a larger proportion of patients with exenatide experienced treatment-emergent adverse events. Exenatide resulted in fewer nonnocturnal hypoglycemic episodes but more gastrointestinal adverse events than lispro.. Adding exenatide to titrated glargine with metformin resulted in similar glycemic control as adding lispro and was well tolerated. These findings support exenatide as a noninsulin addition for patients failing basal insulin.

Exenatide twice daily versus insulin glargine for the treatment of type 2 diabetes in Poland - subgroup data from a randomised multinational trial GWAA.
We explored the safety and efficacy of exenatide BID v. insulin glargine in a subgroup of Polish patients with type 2 diabetes sub-optimally controlled with metformin plus a sulfonylurea, participating in a 26-week randomised, controlled open-label trial.. In Poland, 80 patients (HbA1c 7-10%, BMI 25-45 kg/m(2)) were randomised to exenatide 10 μg BID (n = 40) or insulin glargine once daily (n = 40). We present exploratory analyses on HbA1c, glucose profiles, body weight, hypoglycaemia and adverse events (AEs).. Mean (SD) baseline HbA1c was 7.9% (0.86) for exenatide and 7.8% (1.02) for insulin glargine. At Week 26, LS mean (SEM) HbA1c decreased in both groups (exenatide -0.72% [0.12]; glargine -0.64% [0.12]), as did fasting glucose. Postprandial glucose excursions after breakfast and dinner were smaller in patients treated with exenatide. LS mean (SEM) body weight decreased by -1.9 (0.48) kg with exenatide and increased by 1.6 (0.48) kg with glargine (group difference [95%CI]: -3.5 kg [-4.9 to -2.2]). Hypoglycaemia was low in both groups; nocturnal hypoglycaemia was reported for three v. seven patients (three v. 24 episodes) in the exenatide and glargine groups, respectively. Adverse events were more common with exenatide (nausea n = 22 v. n = 1, vomiting n = 5 v. n = 0, headache n = 8 v. n = 2).. This exploratory analysis confirms that findings from the global study apply to patients treated with exenatide BID and glargine in Poland, showing that exenatide BID was as effective as insulin glargine. Data suggested that changes in HbA1c were similar, with fasting glucose changes greater in the glargine group and postprandial changes greater in the exenatide BID group. Exenatide BID was associated with weight reduction, less nocturnal hypoglycaemia, but more gastrointestinal events compared to glargine.

Oxyntomodulin attenuates exendin-4-induced hypoglycemia in cattle.
Oxyntomodulin (OXM), glucagon, glucagon-like peptide-1 (GLP-1), and exendin-4 (Ex-4) are peptide hormones that regulate glucose homeostasis in monogastric and ruminant animals. Recently, we reported that the insulin-releasing effects of OXM and glucagon in cattle are mediated through both GLP-1 and glucagon receptors. The purpose of this study was to examine the mechanisms of the glucoregulatory actions induced by Ex-4, GLP-1, OXM, and glucagon and the interrelationships among these hormones in cattle. Two experiments were performed in Holstein cattle. In Experiment 1, we initially assessed the effects of intravenous (iv) bolus injection of 0, 0.25, 1, and 2 μg/kg body weight (BW) of Ex-4, GLP-1, and OXM on insulin and glucose concentrations in 3-mo-old intact male Holstein calves. In Experiment 2, we studied insulin and glucose responses to iv coinjection of 0.25 μg of Ex-4 or GLP-1/kg BW with 2 μg of OXM or glucagon/kg BW in 4-mo-old Holstein steers. Administration of peptides and blood sampling were done via a jugular catheter. Plasma was separated and the concentrations of peptides and glucose in plasma were analyzed using radioimmunoassay and enzymatic methods, respectively. Results showed that the potent glucoregulatory action of Ex-4 in 4-mo-old steers was delayed and attenuated when Ex-4 was coinjected with OXM. The decline in plasma glucose concentrations began at 5 min in the Ex-4-injected group (P < 0.05) vs 15 min in the Ex-4 + OXM-injected group (P < 0.05). Plasma concentrations of glucose at 30 min were reduced 26% from basal concentrations in the Ex-4-injected group and 13% in the Ex-4 + OXM-injected group (P < 0.001). Results also showed that the glucose concentrations initially increased in the Ex-4 + glucagon-treated group, but declined to a relatively hypoglycemic condition by 90 to 120 min. In contrast, the glucose concentrations at specific time points between the GLP-1 + OXM-injected group and the OXM-injected group did not differ. Similarly, the glucose concentrations in the GLP-1 + glucagon-injected group did not differ from those in the glucagon-injected group. Because OXM and glucagon mediate glucose concentrations via the glucagon receptor, it is suggested that the potent glucose-lowering action of Ex-4 might include the glucagon receptor antagonistic action of Ex-4.

Combination therapy with insulin glargine and exenatide: real-world outcomes in patients with type 2 diabetes.
To investigate the real-world use of combination insulin glargine/exenatide therapy for type 2 diabetes mellitus (T2DM) and associated treatment persistence and glycemic control.. In this retrospective study, data were extracted from a national US insurance claims database for patients with T2DM for whom insulin glargine and exenatide were co-prescribed in differing order: insulin glargine added after exenatide (EXE+); exenatide added after insulin glargine (GLA+); glargine and exenatide initiated together (GLA + EXE). Patients had continuous health plan coverage for 6 months pre- (baseline) and 1-year post-index (follow-up).. A total of 453 patients were eligible for analysis: 141 patients were included in the EXE+ cohort, 281 in the GLA+ cohort, and 31 in the GLA + EXE cohort. There were significant differences between the groups at baseline, including a significantly lower A1C in the GLA+ versus the EXE+ cohort (p = 0.0023). Around one third of patients stayed on both drugs up until the end of the follow-up period (GLA+: 30.2%; EXE+: 29.0%; GLA + EXE: 29.0%). However, more patients stayed on insulin glargine than on exenatide in each cohort. Significant A1C reductions were observed in each of the cohorts at follow-up: GLA+: -0.4%; EXE+: -0.9%; GLA + EXE: -1.2%; p < 0.01, and were significantly higher in the GLA + EXE and EXE+ cohorts than in the GLA+ cohort (p = 0.03 and p = 0.002, respectively). The mean number of hypoglycemic events increased slightly from baseline but remained low in each of the cohorts (GLA+: 0.12 to 1.42; EXE+: 0.09 to 1.04; GLA + EXE: 0.23 to 1.87 per patient, all p > 0.1).. Combined therapy with insulin glargine and exenatide resulted in A1C reductions in T2DM patients with poor glycemic control without a significantly increased risk of hypoglycemia irrespective of treatment order. Limitations of this study are the between-cohort differences at baseline, lack of a comparator group, and small n number, particularly in the GLA + EXE cohort.

A randomized non-inferiority study comparing the addition of exenatide twice daily to sitagliptin or switching from sitagliptin to exenatide twice daily in patients with type 2 diabetes experiencing inadequate glycaemic control on metformin and sitaglipti
To test the hypothesis that glycaemic control achieved when switching sitagliptin to exenatide twice daily plus metformin is non-inferior to adding exenatide twice daily to sitagliptin and metformin.. Patients with Type 2 diabetes inadequately controlled with sitagliptin plus metformin were randomly assigned to 20 weeks of treatment with twice-daily exenatide plus placebo and metformin (SWITCH, n = 127) or twice-daily exenatide plus sitagliptin and metformin (ADD, n = 128).. Non-inferiority (0.4% margin) of SWITCH to ADD treatment, measured by change in HbA(1c) from baseline to week 20, was not shown {between-treatment difference in least-squares mean [95% CI 3 mmol/mol (0.30%)] [0.8-5.8 (0.07-0.53)]}. A greater reduction (P = 0.012) in HbA(1c) [least-squares mean (se)] was experienced by patients in the ADD group {-7 mmol/mol [-0.68%] [0.9 (0.08)]}, compared with those in the SWITCH group {-4 mmol/mol [-0.38%] [1.0 (0.09)]} and a greater proportion (P = 0.027) of patients in the ADD group (41.7%) reached < 7.0% (< 53 mmol/mol) HbA(1c) target, compared with those in the SWITCH group (26.6%) by week 20. Patients in the ADD group experienced greater fasting serum glucose (P = 0.038) and daily mean postprandial self-monitored blood glucose (P = 0.048) reductions, compared with patients in the SWITCH group, by week 20. Patients in both groups experienced a lower incidence of nausea and vomiting compared with previous exenatide studies.. Non-inferiority of SWITCH to ADD treatment was not supported by the results of this study. In patients with Type 2 diabetes inadequately controlled with sitagliptin plus metformin, adding exenatide provided better glycaemic control than switching to exenatide. These results are consistent with the clinical approach that adding is better than switching to another oral anti-hyperglycaemic medication.

Efficacy and safety profile of exenatide once weekly compared with insulin once daily in Japanese patients with type 2 diabetes treated with oral antidiabetes drug(s): results from a 26-week, randomized, open-label, parallel-group, multicenter, noninferio
Exenatide once weekly (QW) is an extended-release formulation of exenatide, a glucagon-like peptide-1 receptor agonist that reportedly improves glycemic control in patients with type 2 diabetes.. The goal of this study was to test the hypothesis that exenatide QW is noninferior to insulin glargine, as measured by change in glycosylated hemoglobin (HbA(1c)) from baseline to end point (week 26 [primary end point]) in Japanese patients with type 2 diabetes who have inadequate glycemic control with oral antidiabetes drugs.. In this open-label, parallel-group, multicenter, noninferiority registration study, patients were randomized (1:1) to add exenatide QW (2 mg) or once-daily insulin glargine (starting dose, 4 U) to their current oral antidiabetes drug treatment. The primary analysis was change in HbA(1c) from baseline to end point, evaluated by using a last-observation-carried-forward ANCOVA model, with a predefined noninferiority margin of 0.4%. Secondary analyses (a priori) included analysis of superiority for between-group comparisons of change in weight and the proportion of patients reaching HbA(1c) target levels of ≤7.0% or ≤6.5%.. The baseline characteristics of the exenatide QW (215 patients) and insulin glargine (212 patients) treatment groups were similar: mean (SD) age, 57 (10) years and 56 (11) years, respectively; 66.0% and 69.8% male; mean HbA(1c), 8.5% (0.82%) and 8.5% (0.79%); and mean weight, 69.9 (13.2) kg and 71.0 (13.9) kg. Exenatide QW was statistically noninferior to insulin glargine for the change in HbA(1c) from baseline to end point (least squares mean difference, -0.43% [95% CI, -0.59 to -0.26]; P < 0.001), with the 95% CI upper limit less than the predefined noninferiority margin (0.4%). A significantly greater proportion of patients receiving exenatide QW compared with insulin glargine achieved HbA(1c) target levels of ≤7.0% (89 of 211 [42.2%] vs 44 of 210 [21.0%]) or ≤6.5% (44 of 214 [20.6%] vs 9 of 212 [4.2%]) at end point (P < 0.001 for both). Patient weight was reduced with exenatide QW compared with insulin glargine at end point (least squares mean difference, -2.01 kg [95% CI, -2.46 to -1.56]; P < 0.001). Exenatide QW was well tolerated, with a lower risk of hypoglycemia compared with insulin glargine but a higher incidence of injection-site induration.. Exenatide QW was statistically noninferior to insulin glargine for the change in HbA(1c) from baseline to end point; these results suggest that exenatide QW may provide an effective alternative treatment for Japanese patients who require additional therapy to control their diabetes.

Efficacy and tolerability of exenatide monotherapy in obese patients with newly diagnosed type 2 diabetes: a randomized, 26 weeks metformin-controlled, parallel-group study.
Incretin-based therapies provide additional options for treating type 2 diabetes. We aimed to evaluate the efficacy and tolerability of exenatide monotherapy in obese patients with type 2 diabetes.. A 26-week, metformin controlled, parallel-group study was conducted among antidiabetic drug-naive obese patients aged > 18 years, and with type 2 diabetes. Participating patients were randomly assigned to receive exenatide or metformin treatments.. Fifty-nine patients (age (50.5 ± 8.6) years, body mass index (BMI) (30.2 ± 1.6) kg/m(2), and hemoglobin A1C (HbA(1C) (8.2 ± 1.2)%) were enrolled in the study. Glucose control and weight reduction improved in both groups receiving treatment. HbA(1C) and oral glucose tolerance test (OGTT) 2 hour glycemia reduction with exenatide was superior to that obtained with metformin ((-2.10 ± 1.79)% vs. (-1.66 ± 1.38)%, (-5.11 ± 2.68) mmol/L vs. (-2.80 ± 2.70) mmol/L, P < 0.05). Fast plasma glucose (FPG) reduction was not significantly different between the two groups ((-1.8 ± 2.0) mmol/L vs. (-1.6 ± 1.7) mmol/L, P > 0.05). Patients treated with exenatide achieved HbA(1C) of < 7% (97% of patients) and < 6.5% (79%) at end-point, vs. 93% and 73% with metformin (P > 0.05). Greater weight reduction was also achieved with exenatide ((-5.80 ± 3.66) kg) than with metformin ((-3.81 ± 1.38) kg, P < 0.01). Homeostasis model assessment of beta-cell function (HOMA-B) was not significantly increased, but the insulinogenic index and HOMA for insulin sensitivity (HOMA-S) were greatly improved in the exenatide group (P < 0.05). Nausea was the most common adverse effect in exenatide treatment (30% vs. 8%; P < 0.05), but most cases were of mild to moderate intensity. One case in the exenatide group was withdrawn early because of severe nausea. Hypoglycemia events were often observed during the first 4 weeks, with 12% of patients in the exenatide and 3.2% in metformin groups, respectively (P < 0.05). No incidents of severe hypoglycemia were reported.. Exenatide demonstrated more beneficial effects on HbA(1C), weight reduction and insulin resistance during 26 weeks of treatment, but there were more hypoglycemic events and mild-to-moderate nausea compared with metformin. These results suggested that exenatide monotherapy may provide a viable treatment option in newly developed type 2 diabetes.

Exenatide twice daily versus premixed insulin aspart 70/30 in metformin-treated patients with type 2 diabetes: a randomized 26-week study on glycemic control and hypoglycemia.
Hypoglycemia causes recurrent morbidity in patients with type 2 diabetes. This study evaluated if exenatide twice daily (BID) was noninferior to premixed insulin aspart 70/30 BID (PIA) for glycemic control and associated with less hypoglycemia.. In this open-label study, metformin-treated adults with type 2 diabetes were randomized to 26-week treatment with exenatide BID (4 weeks 5 μg, then 10 μg) or PIA.. Exenatide BID (n = 181) was noninferior to PIA (n = 173) for A1C control (least squares [LS] mean change -1.0 vs. -1.14%; difference [95% CI] 0.14 [-0.003 to 0.291]) and associated with a lower risk for hypoglycemia (8.0 vs. 20.5%, P < 0.05). LS mean weight decreased by 4.1 kg and increased by 1.0 kg with PIA (P < 0.001). A total of 39.2 vs. 20.8% of patients reached the composite end point of A1C <7.0%, no weight gain, and no hypoglycemia (P < 0.001; post hoc analysis).. In metformin-treated patients, exenatide BID was noninferior to PIA for glycemic control but superior for hypoglycemia and weight control.

Liraglutide once a day versus exenatide twice a day for type 2 diabetes: a 26-week randomised, parallel-group, multinational, open-label trial (LEAD-6).
Unlike most antihyperglycaemic drugs, glucagon-like peptide-1 (GLP-1) receptor agonists have a glucose-dependent action and promote weight loss. We compared the efficacy and safety of liraglutide, a human GLP-1 analogue, with exenatide, an exendin-based GLP-1 receptor agonist.. Adults with inadequately controlled type 2 diabetes on maximally tolerated doses of metformin, sulphonylurea, or both, were stratified by previous oral antidiabetic therapy and randomly assigned to receive additional liraglutide 1.8 mg once a day (n=233) or exenatide 10 microg twice a day (n=231) in a 26-week open-label, parallel-group, multinational (15 countries) study. The primary outcome was change in glycosylated haemoglobin (HbA(1c)). Efficacy analyses were by intention to treat. The trial is registered with ClinicalTrials.gov, number NCT00518882.. Mean baseline HbA(1c) for the study population was 8.2%. Liraglutide reduced mean HbA(1c) significantly more than did exenatide (-1.12% [SE 0.08] vs -0.79% [0.08]; estimated treatment difference -0.33; 95% CI -0.47 to -0.18; p<0.0001) and more patients achieved a HbA(1c) value of less than 7% (54%vs 43%, respectively; odds ratio 2.02; 95% CI 1.31 to 3.11; p=0.0015). Liraglutide reduced mean fasting plasma glucose more than did exenatide (-1.61 mmol/L [SE 0.20] vs -0.60 mmol/L [0.20]; estimated treatment difference -1.01 mmol/L; 95% CI -1.37 to -0.65; p<0.0001) but postprandial glucose control was less effective after breakfast and dinner. Both drugs promoted similar weight losses (liraglutide -3.24 kg vs exenatide -2.87 kg). Both drugs were well tolerated, but nausea was less persistent (estimated treatment rate ratio 0.448, p<0.0001) and minor hypoglycaemia less frequent with liraglutide than with exenatide (1.93 vs 2.60 events per patient per year; rate ratio 0.55; 95% CI 0.34 to 0.88; p=0.0131; 25.5%vs 33.6% had minor hypoglycaemia). Two patients taking both exenatide and a sulphonylurea had a major hypoglycaemic episode.. Liraglutide once a day provided significantly greater improvements in glycaemic control than did exenatide twice a day, and was generally better tolerated. The results suggest that liraglutide might be a treatment option for type 2 diabetes, especially when weight loss and risk of hypoglycaemia are major considerations.. Novo Nordisk A/S.

Efficacy and tolerability of exenatide monotherapy over 24 weeks in antidiabetic drug-naive patients with type 2 diabetes: a randomized, double-blind, placebo-controlled, parallel-group study.
Evaluation of exenatide monotherapy in patients with type 2 diabetes may be of clinical interest based on improvements in glycemic control and weight that have been reported with the use of exenatide in combination with oral antidiabetic agents.. The aim of this study was to evaluate the efficacy and tolerability of exenatide monotherapy in patients with type 2 diabetes naive to antidiabetic agents and whose disease was inadequately controlled with diet and exercise alone.. This 24-week, double-blind, placebo-controlled, parallel-group study was conducted at 23 centers across the United States, Puerto Rico, Romania, Russia, and India. Patients aged >or=18 years with type 2 diabetes were randomly assigned to receive exenatide 5 microg, exenatide 10 microg, or placebo administered SC BID. Patients were instructed by investigators to maintain their individualized prestudy diet and exercise regimens throughout the study.

The effect of adding exenatide to a thiazolidinedione in suboptimally controlled type 2 diabetes: a randomized trial.
Exenatide therapy is effective in combination with metformin or sulfonylureas for treating type 2 diabetes. Thiazolidinediones (TZDs) also are commonly used, but the efficacy of exenatide with a TZD has not been reported.. To compare the effects of exenatide versus placebo on glycemic control.. Placebo run-in, randomized, double-blind, placebo-controlled trial conducted from May 2004 to August 2005.. 49 sites in Canada, Spain, and the United States.. 233 (exenatide group, n = 121; placebo group, n = 112) patients with type 2 diabetes that was suboptimally controlled with TZD treatment (with or without metformin). Mean (+/-SE) baseline glycated hemoglobin A1c level was 7.9% +/- 0.1%.. Subcutaneous abdominal injections of 10 microg of exenatide or placebo twice daily, added to a TZD (with or without metformin) for 16 weeks.. The primary outcome was change from baseline in hemoglobin A1c level. Other outcomes were fasting serum glucose level, body weight, self-monitored blood glucose level, and any adverse events.. Exenatide treatment reduced hemoglobin A(1c) level (mean difference, -0.98% [95% CI, -1.21% to -0.74%]), serum fasting glucose level (mean difference, -1.69 mmol/L [-30.5 mg/dL] [CI, -2.22 to -1.17 mmol/L {-40.0 to -21.1 mg/dL}]), and body weight (mean difference, -1.51 kg [CI, -2.15 to -0.88 kg]). Sixteen percent of patients in the exenatide group and 2% of patients in the placebo group discontinued treatment because of adverse events. In the exenatide group, 40% (n = 48) of patients experienced nausea (mostly mild [n = 21] or moderate [n = 19]), 13% experienced vomiting, and 11% experienced hypoglycemia. In the placebo group, 15% of patients experienced nausea, 1% experienced vomiting, and 7% experienced hypoglycemia.. Combinations with TZDs and sulfonylureas were not tested. Trial duration was relatively short. Only 71% and 86% of patients in the exenatide and placebo groups, respectively, completed the study.. Exenatide therapy improved glycemic control, reduced body weight, and caused gastrointestinal symptoms more than placebo in patients with type 2 diabetes that was suboptimally controlled with TZD therapy.

Tolerability and efficacy of exenatide and titrated insulin glargine in adult patients with type 2 diabetes previously uncontrolled with metformin or a sulfonylurea: a multinational, randomized, open-label, two-period, crossover noninferiority trial.
This study was conducted to compare the efficacy and safety profiles of exenatide and insulin glargine therapy in patients with type 2 diabetes who had not achieved glucose control with metformin or sulfonylurea monotherapy.. This multinational, randomized, open-label, crossover noninferiority study compared the efficacy of exenatide 10 pg BID and insulin glargine QD (titrated targeting a fasting serum glucose (FSG) level < or =5.6 mmol/L) in patients with type 2 diabetes treated with a single oral antidiabetic agent. The study included two 16-week treatment periods. The primary a priori outcome variable was the change in glycosylated hemoglobin (HbA(lc)). Secondary outcomes included the proportion of patients achieving the American Diabetes Association (ADA) target HbA(lc) of < or =7% and the European Association for the Study of Diabetes target of < or =6.5%, the change in FSG, end-point values and change in the 7-point self-monitored glucose profile, and change in body weight. Adverse events were assessed based on standard laboratory tests and patient reports.. One hundred thirty-eight patients were randomized to study treatment (52.9% female, 47.1% male; 79.7% white; mean [SEM] age, 54.9 [0.8] years; duration of diabetes, 7.4 [0.4] years; body mass index, 31.1 [0.4] kg/m(2); weight, 84.8 [1.4] kg) while continuing to receive metformin (55.1%) or a sulfonylurea (44.9%). The population had a baseline least squares (LS) mean (SEM) HbA(lc) of 8.95% (0.09%) and an LS mean FSG concentration of 12.0 (0.3) mmol/L. Both exenatide and titrated insulin glargine therapy were associated with similar significant changes from baseline in HbA(1c) (both, -1.36% [0.09%]; P < 0.001); the difference between groups was not statistically significant. The LS mean HbA(1c) at end point was above the ADA target with both treatments (exenatide, 7.57% [0.09%]; insulin glargine, 7.58% [0.09%]). Similar proportions of patients achieved an HbA(1c) < or =7% (37.5% and 39.8%, respectively; P = NS) or < or =6.5% (21.5% and 13.6%). Patients lost weight during exenatide treatment, whereas they gained weight during insulin glargine treatment; the between-group difference in weight change was statistically significant (LS mean difference, -2.2 [0.3] kg; 95% CI, -2.8 to-1.7; P < 0.001). Both exenatide and insulin glargine were associated with significant reductions from baseline in FSG (-2.9 [0.2] and -4.1 [0.2] mmol/L, respectively; both, P < 0.001), although the reduction was significantly greater with insulin glargine compared with exenatide (LS mean difference, 1.2 [0.3] mmol/L; 95% CI, 0.7 to 1.7; P < 0.001). Compared with insulin glargine, exenatide was associated with significantly lower 2-hour postprandial glucose (PPG) excursions (P < 0.016) and total daily mean glucose excursion (P < 0.001). The proportions of patients reporting nausea during exenatide and insulin glargine treatment were 42.6% and 3.1%, respectively; the proportions reporting vomiting were 9.6% and 3.1%. The incidence of hypoglycemia in the 2 groups was 14.7% and 25.2% (P = NS).. In this open-label, crossover study, treatment with exenatide or insulin glargine for 16 weeks was associated with similar significant improvements from baseline in HbA(1c), independent of treatment order. The improvements in HbA(1c) from baseline did not differ significantly between treatment groups. Exenatide therapy was associated with significant reductions in body weight and PPG excursions compared with insulin glargine, whereas insulin glargine was associated with a significantly greater reduction in FSG compared with exenatide. These findings provide additional information to guide treatment decisions in patients with type 2 diabetes who are potential candidates for either therapy.

Exenatide versus insulin glargine in patients with suboptimally controlled type 2 diabetes: a randomized trial.
Physicians may use either insulin or exenatide injections for patients with type 2 diabetes mellitus who have poor glycemic control despite taking oral blood glucose-lowering drugs.. To compare effects of exenatide and insulin glargine on glycemic control in patients with type 2 diabetes mellitus that is suboptimally controlled with metformin and a sulfonylurea.. 26-week multicenter, open-label, randomized, controlled trial.. 82 outpatient study centers in 13 countries.. 551 patients with type 2 diabetes and inadequate glycemic control (defined as hemoglobin A1c level ranging from 7.0% to 10.0%) despite combination metformin and sulfonylurea therapy.. Exenatide, 10 microg twice daily, or insulin glargine, 1 daily dose titrated to maintain fasting blood glucose levels of less than 5.6 mmol/L (<100 mg/dL).. Hemoglobin A1c level, fasting plasma glucose level, body weight, 7-point self-monitored blood glucose, standardized test-meal challenge, safety, and tolerability.. Baseline mean hemoglobin A1c level was 8.2% for patients receiving exenatide and 8.3% for those receiving insulin glargine. At week 26, both exenatide and insulin glargine reduced hemoglobin A1c levels by 1.11% (difference, 0.017 percentage point [95% CI, -0.123 to 0.157 percentage point]). Exenatide reduced postprandial glucose excursions more than insulin glargine, while insulin glargine reduced fasting glucose concentrations more than exenatide. Body weight decreased 2.3 kg with exenatide and increased 1.8 kg with insulin glargine (difference, -4.1 kg [CI, -4.6 to -3.5 kg]). Rates of symptomatic hypoglycemia were similar, but nocturnal hypoglycemia occurred less frequently with exenatide (0.9 event/patient-year versus 2.4 events/patient-year; difference, -1.6 events/patient-year [CI, -2.3 to -0.9 event/patient year]). Gastrointestinal symptoms were more common in the exenatide group than in the insulin glargine group, including nausea (57.1% vs. 8.6%), vomiting (17.4% vs. 3.7%) and diarrhea (8.5% vs. 3.0%).. The trial was open-label and did not assess clinical complications related to diabetes. Of the 551 participants, 19.4% of those receiving exenatide and 9.7% of those receiving insulin glargine withdrew from the study. Only 21.6% of the insulin glargine group and 8.6% of the exenatide group achieved the target level for fasting plasma glucose of less than 5.6 mmol/L (<100 mg/dL).. Exenatide and insulin glargine achieved similar improvements in overall glycemic control in patients with type 2 diabetes that was suboptimally controlled with oral combination therapy. Exenatide was associated with weight reduction and had a higher incidence of gastrointestinal adverse effects than insulin glargine.

Effect of intravenous infusion of exenatide (synthetic exendin-4) on glucose-dependent insulin secretion and counterregulation during hypoglycemia.
This study assessed whether glucose-dependent insulin secretion and overall counterregulatory response are preserved during hypoglycemia in the presence of exenatide. Twelve healthy fasted volunteers were randomized in a triple-blind crossover study to receive either intravenous exenatide (0.066 pmol. kg(-1). min(-1)) or placebo during a 270-min stepwise hyperinsulinemic-hypoglycemic clamp (insulin infusion 0.8 mU. kg(-1). min(-1)). Plasma glucose was clamped sequentially at 5.0 (0-120 min), 4.0 (120-180 min), 3.2 (180-240 min), and 2.7 mmol/l (240-270 min). At 270 min, insulin infusion was terminated and plasma glucose increased to approximately 3.2 mmol/l. The time to achieve plasma glucose >/=4 mmol/l thereafter was recorded. Insulin secretory rates (ISRs) and counterregulatory hormones were measured throughout. Glucose profiles were superimposable between the exenatide and placebo arms. In the presence of euglycemic hyperinsulinemia, ISRs in the exenatide arm were approximately 3.5-fold higher than in the placebo arm (353 +/- 29 vs. 100 +/- 29 pmol/min [least-square means +/- SE]). However, ISRs declined similarly and rapidly at all hypoglycemic steps (=4 mmol/l) in both groups. Glucagon was suppressed in the exenatide arm during euglycemia and higher than placebo during hypoglycemia. Plasma glucose recovery time was equivalent for both treatments. The areas under the concentration-time curve from 270 to 360 min for cortisol, epinephrine, norepinephrine, and growth hormone were similar between treatment arms. There were no differences in adverse events. In the presence of exenatide, there was a preserved, glucose-dependent insulin secretory response and counterregulatory response during hypoglycemia.

Utility of
Because management is very different, it is important to differentiate between small focal insulinomas and diffuse pancreatic dysplasia (nesidioblastosis) in patients with confirmed endogenous hyperinsulinaemic hypoglycaemia (EHH). Most insulinomas highly express glucagon-like peptide-1 receptors enabling positron emission tomography-computed tomography imaging with its radiolabelled analogue;. To determine: (i) the utility of Exendin in EHH patients in a clinical setting; and (ii) whether the degree of Exendin uptake differentiates non-insulinoma pancreatogenous hypoglycaemia syndrome (NIPHS) from post-gastric bypass hypoglycaemia (PGBH).. This retrospective study reviewed the clinical, biochemistry and prior imaging findings in confirmed EHH patients referred for Exendin. Accuracy of Exendin was based on surgical findings and treatment outcomes. Finally, average Exendin uptake (SUVmax) of five PGBH studies was compared with the SUVmax of a key NIPHS case report.. Twenty of 25 consecutive patients had confirmed EHH. Exendin located insulinomas in eight of nine patients enabling successful surgical excision with rapid and durable cure. Exendin correctly identified diffuse nesidioblastosis in two of three cases requiring partial pancreatectomy for hypoglycaemia control. All three relapsed within 1.7 years with one needing completion pancreatectomy. Establishing the cause in the remainder relied on other investigations, clinical correlation and response to empirical treatment. Finally, Exendin SUVmax could not distinguish between NIPHS and PGBH.. In EHH patients, Exendin accurately identifies the site of insulinoma and thereby differentiates it from nesidioblastosis but negative findings should not be ignored. Exendin is unlikely to differentiate between normal pancreatic uptake, NIPHS and PGBH.

A Relative Cost of Control Analysis of Once-Weekly Semaglutide Versus Exenatide Extended-Release, Dulaglutide and Liraglutide in the UK.
Once-weekly semaglutide 1 mg is a novel glucagon-like peptide 1 receptor agonist (GLP-1 RA) that, in the SUSTAIN clinical trials, has demonstrated greater reductions in glycated haemoglobin (HbA1c) and body weight than the other GLP-1 RAs exenatide extended-release (ER) 2 mg, dulaglutide 1.5 mg and liraglutide 1.2 mg. The aim of this analysis was to evaluate the relative cost of control of achieving treatment goals in people with type 2 diabetes (T2D) treated with once-weekly semaglutide versus exenatide ER, dulaglutide and liraglutide from a UK perspective.. Proportions of patients reaching HbA1c targets (< 7.0% and < 7.5%), weight loss targets (≥ 5% reduction in body weight) and composite endpoints (HbA1c < 7.0% without weight gain or hypoglycaemia; reduction in HbA1c of ≥ 1% and weight loss of ≥ 5%) were obtained from the SUSTAIN clinical trials. Annual per patient treatment costs were based on wholesale acquisition costs from July 2019 in the UK. Cost of control was calculated by plotting relative treatment costs against relative efficacy.. The annual per patient cost was similar for all GLP-1 RAs. Once-weekly semaglutide was superior to exenatide ER, dulaglutide and liraglutide in bringing patients to HbA1c and weight loss targets, and to composite endpoints. When looking at the composite endpoint of HbA1c < 7.0% without weight gain or hypoglycaemia, exenatide ER, dulaglutide and liraglutide were 50.0%, 21.6% and 51.3% less efficacious in achieving this, respectively, than once-weekly semaglutide. Consequently, the efficacy-to-cost ratios for once-weekly semaglutide were superior to all comparators in bringing patients to all endpoints.. The present study showed that once-weekly semaglutide offers superior cost of control versus exenatide ER, dulaglutide and liraglutide in terms of achieving clinically relevant, single and composite endpoints. Once-weekly semaglutide 1 mg would therefore represent good value for money in the UK setting.

Comparative effectiveness of once-weekly glucagon-like peptide-1 receptor agonists with regard to 6-month glycaemic control and weight outcomes in patients with type 2 diabetes.
A retrospective cohort study was conducted in patients with type 2 diabetes in an electronic medical record database to compare real-world, 6-month glycated haemoglobin (HbA1c) and weight outcomes for exenatide once weekly with those for dulaglutide and albiglutide. The study included 2465 patients: exenatide once weekly, n = 2133; dulaglutide, n = 201; and albiglutide, n = 131. The overall mean (standard deviation [s.d.]) age was 60 (11) years and 54% were men; neither differed among the comparison groups. The mean (s.d.) baseline HbA1c was similar in the exenatide once-weekly (8.3 [1.7]%) and dulaglutide groups (8.5 [1.5]%; P = .165), but higher in the albiglutide group (8.7 [1.7]%; P < .001). The overall mean (s.d.) HbA1c change was -0.5 (1.5)% (P < .001) and this did not differ among the comparison groups in either adjusted or unadjusted analyses. The mean (s.d.) weight change was -1.4 (4.7) kg for exenatide once weekly and -1.6 (3.7) kg for albiglutide (P = .579), but was greater for dulaglutide, at -2.7 (5.7) kg (P = .001). Outcomes were similar in subsets of insulin-naive patients with baseline HbA1c ≥7.0% or ≥9.0%. All agents significantly reduced HbA1c at 6 months, with no significant differences among agents or according to baseline HbA1c in insulin-naive subgroups.

Real-world clinical responses in patients with type 2 diabetes mellitus adding exenatide BID (EBID) or mealtime insulin to basal insulin: a retrospective study using electronic medical record data.
Exenatide twice daily (EBID) and mealtime insulin are effective add-on therapies to basal insulin for type 2 diabetes patients in clinical trials. This study used electronic medical record (EMR) data to evaluate analogous real-world clinical responses.. Adult patients initiating EBID or mealtime insulin as add-on to basal insulin during January 2008-March 2013 were identified in a US EMR database. EBID patients were propensity score matched 1:1 to mealtime insulin patients. Cohorts were followed for 12 months before (baseline) and 6 months after the index. A1C, hypoglycemic events, change in weight, and other clinical measures were evaluated by A1C attainment level (<6.5, < 7, < 7.5, <8, <9%) and baseline A1C.. In total, 1249 EBID patients were matched to 1249 mealtime insulin patients. During follow-up, the percentage reaching A1C levels was similar for EBID vs mealtime insulin cohorts for all attainment levels (<7%: 27.8% vs 24.2%; < 9%: 79.7% vs 79.2%; p = NS). The percentage reaching A1C < 7% was similar for both cohorts with different baseline A1C. EBID patients had less hypoglycemia at all attainment levels (3.1% vs 11.1% [<6.5%]; 2.5% vs 4.7% [<9%]; all p < .03) and more weight loss (-9.0 vs -3.2 lb [<6.5%]; -3.4 vs +0.8 lb [<9%]; all p < .01).. EBID added to basal insulin was as effective in a real-world setting as mealtime insulin added to basal insulin in reducing A1C, with less weight gain and less hypoglycemia for a wide range of A1C attainment levels and baseline values.

Exenatide effects on gastric emptying rate and the glucose rate of appearance in plasma: A quantitative assessment using an integrative systems pharmacology model.
This study aimed to quantify the effect of the immediate release (IR) of exenatide, a short-acting glucagon-like peptide-1 (GLP-1) receptor agonist (GLP-1RA), on gastric emptying rate (GER) and the glucose rate of appearance (GluRA), and evaluate the influence of drug characteristics and food-related factors on postprandial plasma glucose (PPG) stabilization under GLP-1RA treatment. A quantitative systems pharmacology (QSP) approach was used, and the proposed model was based on data from published sources including: (1) GLP-1 and exenatide plasma concentration-time profiles; (2) GER estimates under placebo, GLP-1 or exenatide IR dosing; and (3) GluRA measurements upon food intake. According to the model's predictions, the recommended twice-daily 5- and 10-μg exenatide IR treatment is associated with GluRA flattening after morning and evening meals (48%-49%), whereas the midday GluRA peak is affected to a lesser degree (5%-30%) due to lower plasma drug concentrations. This effect was dose-dependent and influenced by food carbohydrate content, but not by the lag time between exenatide injection and meal ingestion. Hence, GER inhibition by exenatide IR represents an important additional mechanism of its effect on PPG.

Cost-effectiveness of exenatide twice daily vs insulin glargine as add-on therapy to oral antidiabetic agents in patients with type 2 diabetes in China.
To estimate the long-term cost-effectiveness of exenatide twice daily vs insulin glargine once daily as add-on therapy to oral antidiabetic agents (OADs) for Chinese patients with type 2 diabetes (T2DM).. The Cardiff Diabetes Model was used to simulate disease progression and estimate the long-term effects of exenatide twice daily vs insulin glargine once daily. Patient profiles and treatment effects required for the model were obtained from literature reviews (English and Chinese databases) and from a meta-analysis of 8 randomized controlled trials comparing exenatide twice daily with insulin glargine once daily add-on to OADs for T2DM in China. Medical expenditure data were collected from 639 patients with T2DM (aged ≥18 years) with and without complications incurred between January 1, 2014 and December 31, 2015 from claims databases in Shandong, China. Costs (2014 Chinese Yuan [¥]) and benefits were estimated, from the payers' perspective, over 40 years at a discount rate of 3%. A series of sensitivity analyses were performed.. Patients on exenatide twice daily + OAD had a lower predicted incidence of most cardiovascular and hypoglycaemic events and lower total costs compared with those on insulin glargine once daily + OAD. A greater number of quality-adjusted life years (QALYs; 1.94) at a cost saving of ¥117 706 gained was associated with exenatide twice daily vs insulin glargine once daily. (i.e. cost saving of ¥60 764/QALY) per patient.. In Chinese patients with T2DM inadequately controlled by OADs, exenatide twice daily is a cost-effective add-on therapy alternative to insulin glargine once daily, and may address the problem of an excess of medical needs resulting from weight gain and hypoglycaemia in T2DM treatment.

Variability in and predictors of glycaemic responses after 24 weeks of treatment with exenatide twice daily and exenatide once weekly.
The range of glycated haemoglobin (HbA1c) responses and characteristics associated with above-average response to exenatide twice daily and once weekly were examined. Data were pooled from 8 exenatide-twice-daily and 5 exenatide-once-weekly studies. A baseline HbA1c-corrected measure of change in HbA1c after 24 weeks identified high, average and low responses. Multiple linear regression and multivariate generalized estimating equation models identified factors associated with high response. Among 2355 participants (exenatide twice daily, n = 1414; exenatide once weekly, n = 941), baseline HbA1c correlated with change in HbA1c (P < .0001). Across baseline HbA1c levels, the 25th to 75th percentile of HbA1c change ranged from -0.3% to -3.2% with exenatide twice daily and from -0.5% to -3.6% with exenatide once weekly. Asian ethnicity and older age were significantly associated with high response to exenatide twice daily; no factors were significantly associated with response to exenatide once weekly. These data provide clinically useful information for estimating the likelihood that, depending on baseline HbA1c, an individual can achieve HbA1c goals. The association between Asian ethnicity, age and high response to exenatide twice daily may relate to the specific effects of exenatide twice daily on postprandial glucose.

Treatment Outcomes and Tolerability Following Initiation of GLP-1 Receptor Agonists Among Type 2 Diabetes Patients in Primary Care Practices in Germany.
The aim was to investigate real-world treatment outcomes and tolerability of GLP-1 receptor agonist (GLP-1RA) therapy in patients with type 2 diabetes in Germany.. Patients from 323 primary care practices who started any GLP-1RA therapy (89 Byetta, 108 Bydureon, 347 Victoza patients) between January 1, 2011, and December 31, 2013 (index date) were analyzed retrospectively (Disease Analyzer database, Germany). Changes from baseline in HbA1c, weight, and hypoglycemia were evaluated in 3 follow-up periods of 0-6, 7-12, and 13-18 months.. A total of 544 diabetes patients (mean age: 57.9 years; men: 54%) were eligible for the study. Mean (SD) HbA1c (%) decreased from 8.3 (1.4) at baseline to 7.4 (1.2) in 6 months, 7.6 (1.3) in 7-12 months and 7.6 (1.4) in 13-18 months, respectively ( P < .001 for all), while the proportion of patients with HbA1c <7% increased from 15% at baseline to 38%, 36% and 35% in the corresponding periods ( P < .0001 for all). Multivariate-adjusted beta coefficients corresponding to changes in HbA1c (%) from baseline were -.52, -.44, and -.44, respectively, in the follow-up periods for baseline HbA1c (%) ( P < .0001 for all). The prevalence of hypoglycemia at baseline was 0.7%; this did not change significantly after treatment.. In clinical practice, GLP-1RA treatment was associated with improved glycemic control without increased hypoglycemia for up to 18 months. The higher the baseline HbA1c, the greater the HbA1c reduction recorded.

The Influence of Varying Cost Formats on Preferences.
Numerous studies have found that cost strongly influences patients' decision making. The objective of this study was to explore the impact of varying cost formats on patients' preferences.. Mechanical Turk workers completed a choice-based conjoint (CBC) survey. The CBC survey was designed to examine stated preferences for the use of second-line agents to treat diabetes across 5 attributes: route of administration, efficacy, risk of low blood sugar, frequency of checking blood sugar levels, and cost. We developed 7 versions of the CBC survey that were identical except for the cost attribute. We described cost in terms of: Affordability, Monthly Co-pay, Dollar Sign Rating, How Expensive, or How Cheap compared with other medications, Working Hours Equivalent (per mo) and Percent of Monthly Income. The resulting part-worth utilities were used to calculate the relative importance of cost and to estimate treatment preferences for exenatide, a sulfonylurea, and insulin.. The relative impact of cost varied significantly across the 7 formats. Cost had the greatest influence on participants' decisions when framed in terms of Affordability [mean (SD) relative importance, 37.3 (0.9)] and the lowest influence when framed in terms of How Cheap (compared with other drugs) [12.1 (0.9)]. A sulfonylurea was strongly preferred across 4 of the 7 formats. Preference for insulin, the most effective, albeit riskiest, option was low across all cost formats.. The format used to describe cost affects how the attribute impacts patients' preferences. Individuals are most cost-sensitive when cost is framed in terms of affordability and least cost-sensitive when cost is described in terms of how cheap the medication is compared with others.

Comparison of trajectories of self-monitored glucose levels by hypoglycemia status over 52 weeks of treatment with insulin glargine or exenatide once weekly.
Self-monitoring of blood glucose (SMBG) is used as a means to detect and prevent hypoglycemia in patients with diabetes. However, information on the longitudinal measures (trajectory) of SMBG-based pre- and postprandial glucose fluctuations over time in relation to hypoglycemia is limited. Among patients treated with exenatide once weekly (EQW) or insulin glargine (IG), this study compared SMBG profiles over 52 weeks between patients who did and did not experience hypoglycemia.. Pooled patient-level 52-week longitudinal data of treatment with EQW (n = 531) or IG (n = 219) from three controlled trials were analyzed.. The proportion of patients with at least one episode of hypoglycemia in the EQW and IG groups was 23% and 54%, respectively. The preprandial glucose measures from SMBG were significantly lower among patients who experienced hypoglycemia in both treatment groups compared with those who did not. In patients who experienced hypoglycemia, the average preprandial glucose levels over 52 weeks were lower by 0.64 and 0.66 mmol/L in the EQW and IG groups, respectively (P < 0.01 in both cases) compared with those without hypoglycemia. The average postprandial levels were not significantly different between patients who did and did not experience hypoglycemia in both treatment groups. Among patients with hypoglycemia, the average prebreakfast glucose trajectory was higher by 0.48 mmol/L in the EQW compared with the IG group.. This study has revealed differential trajectories of pre- and postprandial glucose profiles between patients with and without hypoglycemia. However, the SMBG trajectories were similar between patients treated with EQW and IG.

99mTc Labeled Glucagon-Like Peptide-1-Analogue (99mTc-GLP1) Scintigraphy in the Management of Patients with Occult Insulinoma.
The aim of this study was to assess the utility of [Lys40(Ahx-HYNIC-99mTc/EDDA)NH2]-exendin-4 scintigraphy in the management of patients with hypoglycemia, particularly in the detection of occult insulinoma.. Forty patients with hypoglycemia and increased/confusing results of serum insulin and C-peptide concentration and negative/inconclusive results of other imaging examinations were enrolled in the study. In all patients GLP-1 receptor imaging was performed to localise potential pancreatic lesions.. Positive results of GLP-1 scintigraphy were observed in 28 patients. In 18 patients postsurgical histopathological examination confirmed diagnosis of insulinoma. Two patients had contraindications to the surgery, one patient did not want to be operated. One patient, who presented with postprandial hypoglycemia, with positive result of GLP-1 imaging was not qualified for surgery and is in the observational group. Eight patients were lost for follow up, among them 6 patients with positive GLP-1 scintigraphy result. One patient with negative scintigraphy was diagnosed with malignant insulinoma. In two patients with negative scintigraphy Munchausen syndrome was diagnosed (patients were taking insulin). Other seven patients with negative results of 99mTcGLP-1 scintigraphy and postprandial hypoglycemia with C-peptide and insulin levels within the limits of normal ranges are in the observational group. We would like to mention that 99mTc-GLP1-SPECT/CT was also performed in 3 pts with nesidioblastosis (revealing diffuse tracer uptake in two and a focal lesion in one case) and in two patients with malignant insulinoma (with the a focal uptake in the localization of a removed pancreatic headin one case and negative GLP-1 1 scintigraphy in the other patient).. 99mTc-GLP1-SPECT/CT could be helpful examination in the management of patients with hypoglycemia enabling proper localization of the pancreatic lesion and effective surgical treatment. This imaging technique may eliminate the need to perform invasive procedures in case of occult insulinoma.

Dynamic risk factors associated with non-severe hypoglycemia in patients treated with insulin glargine or exenatide once weekly.
Glycemic control in patients with type 2 diabetes is a dynamic process, and changes in risk factors affecting the incidence of hypoglycemia are not well understood. This study explored the association of longitudinal interactive effects of clinical risk factors and concomitant medications on hypoglycemia risk in patients treated with insulin glargine (IG) or exenatide once weekly (EQW).. Pooled patient-level 52-week longitudinal data of treatment with EQW (n = 541) or IG (n = 223) from three controlled trials were analyzed.. Proportions of patients with at least one episode of hypoglycemia in the EQW and IG groups were 23% and 54%, respectively. Compared with patients with HbA1c ≥7% (53 mmol/mol) over time, patients with HbA1c <7% had significantly higher hypoglycemia risk in both groups (95% confidence intervals [CI] of odds ratios [OR]: EQW-1.21, 2.81; IG- 6.26, 9.84). The patterns of interaction effect of changing body mass index (BMI) and HbA1c on hypoglycemia risk differed in the two treatment groups: patients with with BMI >35 kg/m(2) had a 119% increased hypoglycemia risk in the EQW group, but a 57% reduced risk in the IG group. Sulfonylurea-treated patients in the EQW and IG groups had 4.7- and 3-fold additional hypoglycemia risk, respectively, versus non-sulfonylurea-treated patients.. This study revealed differential effects of tight glycemic control and itsinteraction with treatment-induced changes in BMI on hypoglycemia risk its interaction in patients treated with EQW and IG. The residual adverse effect of sulfonylurea was higher in EQW-treated patients.

Pulmonary administered palmitic-acid modified exendin-4 peptide prolongs hypoglycemia in type 2 diabetic db/db mice.
Hypoglycemia caused by palmitic-acid modified exendin-4 (Pal-Ex4) administered via the pulmonary route was evaluated and compared with that caused by native Ex4. Pal-Ex4 and Ex4 in solution (each 50 μl) were administered using a microsprayer directly into the trachea of type 2 diabetic db/db mice at 75 or 150 nmol/kg. The lung depositions of Cy5.5-labeled Ex4 or Pal-Ex4 were monitored using an infrared imaging system after administration. The hypoglycemia caused by Pal-Ex4 was found to be 3.4 and 2.3 times greater than that caused by native Ex4 at 75 and 150 nmol/kg, respectively. Furthermore, time to blood glucose level (BGL) rebound to >150 mg/dl for Pal-Ex4 was 3.5 times greater than that of Ex4 (18.1 h vs. 5.2 h at 150 nmol/kg). In particular, the time taken for Pal-Ex4 to reach a BGL nadir was significantly greater than that of Ex4 (~8 h versus 4 h). Furthermore, lung deposition images clearly showed that Pal-Ex4 was slowly absorbed from lungs and barely distributed into kidneys until 8 h post-administration. It is likely that the prolonged hypoglycemia exhibited by Pal-Ex4 was due to; (i) delayed absorption in the lungs and (ii) albumin-binding in the circulation. The study demonstrates that palmitic acid-modified exendin-4 should be viewed as a long-acting inhalation candidate for the treatment of type 2 diabetes.

Hypoglycemia in patients with type 2 diabetes using concomitant exenatide BID and long-acting insulin therapy.
The objective of this study was to examine the frequency of hypoglycemia among patients with type 2 diabetes who had concomitantly used exenatide BID (exenatide) and long-acting insulin and continued this combination vs those who continued long-acting insulin alone.. Retrospective analyses, using a large managed care database, were used to estimate the frequency of hypoglycemia (episodes/patient/6 months) for patients who concomitantly used exenatide and long-acting insulin during a 6-month follow-up period.. From among 2082 patients on concomitant exenatide and long-acting insulin, those who continued this combination (n=472) had a lower frequency of hypoglycemia compared to those who remained on long-acting insulin alone (n=312) (0.03 ± 1.9 vs 0.10 ± 1.01 [episodes/patient/6 months]; p<0.0001).. Only hypoglycemia that required medical intervention (coded for hypoglycemia) was captured. The study could not evaluate any association between insulin dose titration and hypoglycemia or examine other outcomes such as HbA1c, weight, and body mass index, due to lack of data availability.. Patients who concomitantly used exenatide BID and long-acting insulin experienced a lower rate of hypoglycemia.

One-year metabolic outcomes in patients with type 2 diabetes treated with exenatide in routine practice.
The study objective was to analyze, in everyday practice, the long-term metabolic effects of exenatide (for 9 and 12 months) in patients with type 2 diabetes not responding to treatments with metformin and sulphonylurea at maximum dosages.. A total of 299 type 2 diabetics were recruited from 14 centres specializing in diabetes care across Belgium. Main study endpoints were changes in HbA(1c), weight and waist circumference, and tolerability and compliance. Two patient cohorts were analyzed for effectiveness, with data available at 9 (n=90) and 12 (n=94) months of follow-up.. Significant decreases in HbA(1c) of -1.3% and -1.6% were observed in the 9- and 12-month cohorts, respectively (P<0.001). The decrease in HbA(1c) was greater in patients with higher baseline levels (P<0.001), and the response was independent of baseline weight, body mass index (BMI), age, gender and diabetes duration. A progressive reduction of weight (4.9 kg) was also observed in the two cohorts at 9 and 12 months (P<0.001), with greater weight loss in patients with higher baseline BMI (P=0.046) and in female subjects (P=0.025). Waist circumference also decreased from baseline to endpoints. A correlation was observed between reduction in HbA(1c) and weight loss (P=0.019). Side effects, mainly of gastrointestinal origin, were reported in 33% (93/284 patients in the safety cohort). The rate of hypoglycaemia was 3.5%. Treatment was discontinued in 27% of patients (n=77) mainly due to drug inefficacy (53%, n=41) or adverse events (26%, n=20), or both (8%, n=6).. Exenatide leads to long-term improvement of glycaemic control as well as weight loss in a majority of patients not responding to combined oral drug therapy in real-world clinical practice. However, no baseline factors predictive of response could be identified. Exenatide can be considered an effective treatment option in such patients, including those with high baseline HbA(1c) and long duration of diabetes.

Effectiveness of exenatide in Asian Indians in a clinical care setting.
This study reports on the effectiveness of exenatide compared to insulin glargine or NPH insulin in patients with type 2 diabetes mellitus, unable to achieve glycemic control with oral glucose-lowering therapies in a clinical care setting.. Patients with type 2 diabetes mellitus (n = 47) whose glycemia was not controlled adequately with oral hypoglycemic agents at maximum recommended therapeutic doses were initiated on exenatide therapy. Age-, sex-, and body mass index-matched patients receiving insulin glargine (n = 54) or NPH insulin (n = 23) served as controls. Data analysis included glycated hemoglobin, fasting and postprandial plasma glucose, lipid profile, body weight, and the occurrence of hypoglycemia.. A statistically significant reduction in glycated hemoglobin value was noted after initiating exenatide (pre-exenatide 9.7 +/- 1.4% vs. post-exenatide 8.7 +/- 1.5%; P < 0.05), which was comparable to values after insulin glargine (9.8 +/- 1.1% vs. 9.0 +/- 1.5%, respectively; P < 0.05) and NPH insulin (9.6 +/- 1.4% vs. 8.9 +/- 1.3%, respectively; P < 0.05). Exenatide therapy was associated with net weight loss (mean, 1.6 kg), but therapy with insulin glargine and NPH insulin was associated with weight gain (1.8 and 2.3 kg, respectively).. In a group of select Asian Indian type 2 diabetes patients with secondary failure to oral hypoglycemic agents seen at a diabetes center, exenatide treatment in combination with oral drug regimens resulted in significant lowering of glycated hemoglobin similar to insulin glargine or NPH insulin but with the additional benefit of weight loss, albeit a small amount.

Synthesis and evaluation of human serum albumin-modified exendin-4 conjugate via heterobifunctional polyethylene glycol linkage with protracted hypoglycemic efficacy.
Albumin conjugation is considered to be one of the most effective means of protracting the short in vivo lifespans of peptides and proteins. Here, we present a new long-acting antidiabetic exendin-4 conjugate linked with human serum albumin (HSA) via polyethylene glycol (PEG). As a first step toward synthesizing this conjugate, three artificial sulfhydryl groups were introduced in HSA using 2-iminothiolane at pH 8.0. This thiolated HSA was further reacted with the monomer fraction of exendin-4 (6 equiv) conjugated with maleimide-PEG(5k)-N- hydroxysuccinimide (MAL-PEG(5k)-NHS) for 3 h. Because of the presence of PEG molecules, the resulting conjugate (HSA-PEG-Ex4) was found to have a greater apparent molecular weight and a larger particle size (ca. 195 kDa and 9.48 +/- 0.74 nm) than those of HSA-exendin-4 without the PEG linker (HSA-Ex4, ca. 84.3 kDa and 7.77 +/- 0.98 nm). Although the receptor binding affinity of HSA-PEG-Ex4 on RIN-m5F cells was significantly lower than that of Ex4, its antihyperglycemic efficacy was slightly higher than that of Ex-4 and HSA-Ex4 in type 2 diabetic db/db mice. Furthermore, HSA-PEG-Ex4 had greater circulating t(1/2) and AUC(inf) values than HSA-Ex and native exendin-4 by 2.1- and 10.3-fold, respectively. Accordingly, its hypoglycemic duration was greatly increased to 31.0 h at a dose of 250 nmol/kg vs that of native Ex4 (7.0 h). Results show that the HSA-PEG-Ex4 conjugate produced has distinct advantages over HSA-Ex4 without PEG. We believe that this exendin-4 derivative, which has the merits of albumin conjugation and PEGylation, has considerable potential as a novel type 2 antidiabetic agent.

A comparison of preferences for two GLP-1 products--liraglutide and exenatide--for the treatment of type 2 diabetes.
To use time trade-off (TTO) to compare patient preferences for profiles of two glucagon-like peptide (GLP-1) products for the treatment of type 2 diabetes (liraglutide and exenatide) that vary on four key attributes - efficacy (as measured by hemoglobin A(1C)), incidence of nausea, incidence of hypoglycemia, and dosing frequency (QD vs. BID) - and measure the contribution of those attributes to preferences.. A total of 382 people with T2DM were recruited to participate in an internet-based survey consisting of a series of health-related questions, a conjoint exercise and a set of time trade-off items. In the conjoint exercise, respondents were presented with eight pairs of hypothetical GLP-1 profiles, and completed a time-tradeoff exercise for each pair.. The product profile representing liraglutide was preferred by 96% of respondents and resulted in significantly higher health utilities (0.038) than the product profile representing exenatide (0.978 vs. 0.94, p < 0.05). Estimated preference scores from the conjoint analysis revealed that efficacy measured by hemoglobin A(1C) is the most important attribute, followed by nausea, hypoglycemia, and dosing schedule.. On-line participants may not represent 'typical' type 2 diabetes patients, and brief product profiles represented results from clinical trials, not clinical practice. Based on the four attributes presented, patients prefer liraglutide over exenatide. Preference is based on superior efficacy and less nausea more than less hypoglycemia and once-daily dosing.

Patient characteristics, drug adherence patterns, and hypoglycemia costs for patients with type 2 diabetes mellitus newly initiated on exenatide or insulin glargine.
Examine real-world effectiveness and hypoglycemia cost burden in patients with type 2 diabetes newly initiated on exenatide or insulin glargine.. Retrospective cohort study describing patient characteristics, drug adherence patterns, and 1-year hypoglycemia rates with associated costs using an administrative claims database. Adult subjects with type 2 diabetes had an initial claim for exenatide or insulin glargine between May 1, 2005 and June 30, 2007, and had continuous eligibility for >or= 6 months pre- and >or= 12 months post-initiation.. The exenatide cohort (n = 3262) was 53 +/- 10 years (+/-SD); 54% female. The insulin glargine cohort (n = 3038) was 56 +/- 12 years; 41% female. The mean Deyo-Charlson comorbidity index score was 1.45 for exenatide versus 1.82 for insulin glargine (p < 0.001). Baseline OAD use rates for exenatide and insulin glargine, respectively, were 77% versus 69% metformin; 47% versus 65% sulfonylurea; 50% versus 49% thiazolidinedione; 56% versus 60% multiple OAD. For patients with two or more pharmacy claims for exenatide or insulin glargine, the 12-month medication possession ratio (MPR) was 68 +/- 29% for exenatide and 58 +/- 28% for insulin glargine (p < 0.001). MPR >or= 80% was higher for exenatide (p < 0.001) and fewer patients discontinued therapy (p < 0.001). The probability of a hypoglycemic event was significantly lower for exenatide (p < 0.005), resulting in lower associated annual costs.. This study provides the first real-world observational comparison of type 2 diabetes patients newly initiated on exenatide or insulin glargine. Exenatide patients had a lower comorbidity burden, better drug adherence, and a lower rate of hypoglycemic events with associated costs. Retrospective database analyses examine medical care utilization in large populations using a relatively inexpensive and expedient approach. However, data are only representative of a commercial health-care plan with limited information on multiple variables usually collected during clinical trials.
