exenatide non diabetic

M Zhou, M T S Mok, H Sun, A W Chan, Y Huang, A S L Cheng, G Xu
Epidemiological studies have demonstrated a close association of type 2 diabetes and hepatocellular carcinoma (HCC). Exenatide (Ex-4), a potent diabetes drug targeting glucagon-like peptide-1 receptor (GLP-1R), is protective against non-alcoholic fatty liver disease (NAFLD). However, the Ex-4 function and GLP-1R status have yet been explored in HCC. Herein we investigated the effect of Ex-4 in diethylnitrosamine (DEN)-treated mice consuming control or high-fat high-carbohydrate diet. Administration of Ex-4 significantly improved obesity-induced hyperglycemia and hyperlipidemia and reduced HCC multiplicity in obese DEN-treated mice, in which suppressed proliferation and induced apoptosis were confined to tumor cells...

Polycystic ovarian syndrome (PCOS) affects many women of child-bearing age and is characterized by hyperandrogenism, ovulatory and metabolic dysfunction. A primary treatment goal is weight reduction. The weight loss effects of glucagon-like peptide-1 receptor agonists (GLP-1RA), previously demonstrated in diabetic and obese non-diabetic patients, offer a unique opportunity to expand the medical options available to PCOS patients. Areas covered: Available clinical trials of glucagon-like peptide-1 receptor agonist therapy in PCOS were reviewed...

OBJECTIVE: Schizophrenia is associated with profound cognitive and psychosocial impairments. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are used for diabetes and obesity treatment, and animal studies have indicated cognitive-enhancing effects. In this investigator-initiated, double-blind, randomized, placebo-controlled trial, we tested non-metabolic effects of exenatide once-weekly (Bydureon™) in obese, antipsychotic-treated patients with schizohrenia spectrum disorder. METHOD: Before and after 3 months of exenatide (N = 20) or placebo (N = 20) treatment, patients were assessed with the following: Brief Assessment of Cognition in Schizophrenia (BACS), Rey-Osterreith complex figure test (REY), Short-Form Health Survey (SF-36), Personal and Social Performance Scale (PSP) and the Positive and Negative Syndrome Scale (PANSS)...

AIM: Glucagon-like Peptide 1 Receptor Agonists (GLP1-RA) has been associated with an increased risk of pancreatitis and pancreatic cancer. Prior meta-analyses of randomized controlled trials failed to show any significant increase of risk; however, those meta-analyses did not include the recently published cardiovascular outcome trials (CVOT) with GLP1-RA, which provide a substantial additional body of data. The aim of the present meta-analysis is to assess the effect of GLP1-RA on pancreatitis, pancreatic cancers and cholelithiasis...

BACKGROUND: The prevalence of type 2 diabetes mellitus (T2DM) and obesity is increasing in Korea. Clinical studies in patients with T2DM have shown that combining the glucagon-like peptide-1 receptor agonist exenatide twice daily with basal insulin is an effective glucose-lowering strategy. However, these studies were predominantly conducted in non-Asian populations. METHODS: We conducted a subgroup analysis of data from a multinational, 30-week, randomized, open-label trial to compare the effects of exenatide twice daily (n=10) or three times daily mealtime insulin lispro (n=13) among Korean patients with T2DM inadequately controlled (glycosylated hemoglobin [HbA1c] >7...

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 are the standard of medical care in schizophrenia, but the drugs are associated with severe metabolic side effects such as 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...

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...
