AIMS: Schizophrenia is associated with cardiovascular co-morbidity and a reduced life-expectancy of up to 20 years. Antipsychotics are dopamine D2 receptor antagonists and the standard of medical care in schizophrenia, but the drugs are associated with severe metabolic side effects like obesity and diabetes. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are registered for treatment of both obesity and type 2 diabetes. We investigated metabolic effects of the GLP-1RA, exenatide once-weekly, in non-diabetic, antipsychotic-treated, obese patients with schizophrenia...

Approximately 90% of T2D patients in the US are diagnosed and treated in the primary care setting, and the majority of the burden of disease management falls to primary care providers. Here, we discuss the clinical data for once weekly dulaglutide, e.g. the results of seven completed Phase 3 trials, patient preference studies, patient reported outcomes (PRO), and clinical data surrounding the dulaglutide administration device. Dulaglutide 1.5 mg once weekly demonstrated superiority to placebo, metformin, sitagliptin, exenatide BID, and insulin glargine (in 2 trials), and non-inferiority to liraglutide in reduction of HbA1c from baseline, with an acceptable safety profile...

Exenatide is a synthetic version of the 39-mer peptide of Exendin-4, which is an FDA-approved therapeutic against Type II diabetes mellitus. However, exenatide has a very short in-serum half-life and PEGylation have been performed to improve its in-serum stability. PEGylation often yields multivalent binding to non-specific residues, and the desired species should be carefully separated by chromatographies. In this study, we first devised an aqueous-phase, two-step PEGylation process. This consists of thiolation of Lys 12 and 27 residues followed by attachment of PEG-maleimide (10kD) to thiol groups...

BACKGROUND/OBJECTIVES: Exenatide, a glucagon-like peptide-1 (GLP-1) receptor agonist, is increasingly used in obese or overweight patients with diabetes. However, its safety profile and effects on weight loss in non-diabetic obese or overweight population remain unclear. We aimed to evaluate efficacy and safety of exenatide in obese or overweight participants without diabetes. METHODS: We searched up to January 2016 in MEDLINE (Ovid SP), EMBASE (Ovid SP), Cochrane Central Register of Controlled Trials (CENTRAL), some Chinese databases and ClinicalTrials...

Dulaglutide (Trulicity®) is a new once-weekly agonist of Glucagon-Like Peptide-1 (GLP-1) receptors indicated in the treatment of type 2 diabetes. Phase III clinical trials in AWARD programme demonstrated the efficacy and safety of dulaglutide in patients with type 2 diabetes treated by diet and exercise, metformin, a combination of metformin and a sulfonylurea or metformin and pioglitazone or even by supplements of prandial insulin. In the AWARD programme, dulaglutide (subcutaneous 0.75 or 1.5 mg once weekly) exerted a greater glucose-lowering activity than metformin, sitagliptin, exenatide or insulin glargine, and was non-inferior to liraglutide 1...

AIM: Fibroblast growth factor 21 (FGF21) has been demonstrated to be a metabolic regulator with beneficial effects. Several studies have shown that type 2 diabetes mellitus (T2DM) patients have increased FGF21 levels and decreased expression of FGF receptors, suggesting a state of 'FGF21 resistance'. The aim of this study was to investigate the effects of the glucagon-like peptide (GLP)-1 receptor agonist exenatide on FGF21 levels and other metabolic parameters in patients with newly diagnosed T2DM...

Dulaglutide (DU) is a once weekly glucagon-like peptide-1 receptor agonist (GLP-1 RA) approved for the treatment of type 2 diabetes mellitus (T2DM). Glycaemic efficacy and safety characteristics of DU have been assessed in six Phase 3 studies in the AWARD program. The objective of this review article is to summarise these results from the 6 completed AWARD studies. At the primary endpoint, in 5 of the 6 studies, once weekly dulaglutide 1.5 mg was superior to the active comparator (exenatide, insulin glargine [two studies], metformin, and sitagliptin), with a greater proportion of patients reaching glycated haemoglobin A1c (HbA1c) targets of <7...

BACKGROUND: Prader-Willi syndrome (PWS) is associated with hyperphagia and hyperghrelinemia with major morbidity because of obesity without effective medical treatment targeting hyperphagia. Exenatide (Byetta [synthetic Exendin-4]; AstraZeneca, Wilmington DE) is a GLP-1 receptor agonist which reduces appetite and weight and may be an effective treatment in PWS. OBJECTIVE: The objective of this study is to determine the effect of a 6-month trial of exenatide on appetite, weight and gut hormones in youth with PWS...

AIM: Diabetes mellitus type 2 (DMT2) and non-alcoholic fatty liver disease (NAFLD) are both characterized by decreased circulating adiponectin. Recently, glucagon-like peptide-1 receptor agonists have been shown to induce adiponectin's expression. However, their interaction on clinical grounds needs to be further elucidated. METHODS: DMT2 patients with abnormal aminotransferases were screened for NAFLD and subjected to liver biopsy (group A, n=17). A subgroup of patients (n=110), after assessed for eligibility criteria, was blindly randomized to receive either 6-month exenatide supplementation on glargine insulin (group B) or intense, self-regulated, insulin therapy alone (group C)...

Dulaglutide is a new once-weekly glucagon-like peptide-1 receptor agonist for the management of hyperglycemia in adult patients with type 2 diabetes. It stimulates dose-dependent insulin secretion and reduces glucagon secretion, both in a glucose-dependent manner. Efficacy on blood glucose control and safety were demonstrated in the large AWARD program in type 2 diabetic patients treated with diet, metformin, dual oral therapy or insulin lispro with or without metformin, confirming findings of pilot studies in Caucasian patients and data in Japanese patients...

Glucagon-like peptide-1 receptor (GLP-1R) agonists are a rapidly growing class of drugs developed for treating type-2 diabetes mellitus. Patients with diabetes carry an up to 5-fold greater mortality risk compared to non-diabetic patients, mainly as a result of cardiovascular diseases. Although beneficial cardiovascular effects have been reported, exact mechanisms of GLP-1R-agonist action in the heart, especially in human myocardium, are poorly understood. The effects of GLP-1R-agonists (exenatide, GLP-1(7-36)NH2, PF-06446009, PF-06446667) on cardiac contractility were tested in non-failing atrial and ventricular trabeculae from 72 patients...

Several nutrition, food and dietary compounds have been suggested to be involved in the onset and maintenance of depressive disorders and in the severity of depressive symptoms. Nutritional compounds might modulate depression associated biomarkers and parallel the development of depression, obesity and diabetes. In this context, recent studies revealed new mediators of both energy homeostasis and mood changes (i.e. IGF-1, NPY, BDNF, ghrelin, leptin, CCK, GLP-1, AGE, glucose metabolism and microbiota) acting in gut brain circuits...

PURPOSE: The glucagon-like peptide (GLP)-1 agonist exenatide shows the same multiple effects on glucose homeostasis as native GLP-1, which can reduce blood glucose levels in individuals with type-2 diabetes mellitus (T2DM). However, its underlying action mechanism on glucose metabolism in the skeletal muscle of T2DM cases is unknown. We investigated the effects and action mechanisms of exenatide on insulin resistance (IR) in the skeletal muscle of high-fat diet and low-dose streptozotocin-induced T2DM rats...

Glucagon-like peptide-1 (GLP-1) analogs, such as exenatide, have played an important role as antidiabetic medications in the treatment of type 2 diabetes (T2DM). Like most other hypoglycemic agents, exenatide has a number of actions, including lowering blood glucose, promoting weight loss, improving insulin resistance, and protecting islet β-cells. Although GLP-1 analogs, combined with other antidiabetic medications, have excellent performance in T2DM, some side effects and imperfections limit its use in clinical practice...

PURPOSE: Quantitative molecular imaging of beta cell mass (BCM) would enable early detection and treatment monitoring of type 1 diabetes. The glucagon-like peptide-1 (GLP-1) receptor is an attractive target due to its beta cell specificity and cell surface location. We quantitatively investigated the impact of plasma clearance and receptor internalization on targeting efficiency in healthy B6 mice. PROCEDURES: Four exenatide-based probes were synthesized that varied in molecular weight, binding affinity, and plasma clearance...

BACKGROUND: Exenatide once weekly (QW) is a glucagon-like peptide-1 receptor agonist (GLP-1RA) for the treatment of type 2 diabetes. Safety and tolerability are key considerations in treatment selection. This analysis examines the safety and tolerability profile of exenatide QW, other approved GLP-1RAs (exenatide twice daily and liraglutide once daily), and a pooled population of commonly used non-GLP-1RA treatments. METHODS: Intent-to-treat populations from eight randomized Phase III trials with 24-week and 30-week comparator-controlled periods were analyzed...
