OBJECTIVEThis multicenter, open-label, parallel-arm study compared the efficacy and safety of exenatide once weekly (EQW) with titrated insulin detemir in patients with type 2 diabetes inadequately controlled with metformin (with or without sulfonylureas).RESEARCH DESIGN AND METHODSPatients were randomized to EQW (2 mg) or detemir (once or twice daily, titrated to achieve fasting plasma glucose ≤5.5 mmol/L) for 26 weeks. The primary outcome was proportion of patients achieving A1C ≤7.0% and weight loss ≥1.0 kg at end point, analyzed by means of logistic regression. Secondary outcomes included measures of glycemic control, cardiovascular risk factors, and safety and tolerability.RESULTSOf 216 patients (intent-to-treat population), 111 received EQW and 105 received detemir. Overall, 44.1% (95% CI, 34.7–53.9) of EQW-treated patients compared with 11.4% (6.0–19.1) of detemir-treated patients achieved the primary outcome (P < 0.0001). Treatment with EQW resulted in significantly greater reductions than detemir in A1C (least-square mean ± SE, −1.30 ± 0.08% vs. −0.88 ± 0.08%; P < 0.0001) and weight (−2.7 ± 0.3 kg vs. +0.8 ± 0.4 kg; P < 0.0001). Gastrointestinal-related and injection site–related adverse events occurred more frequently with EQW than with detemir. There was no major hypoglycemia in either group. Five (6%) patients in the EQW group and six (7%) patients in the detemir group experienced minor hypoglycemia; only one event occurred without concomitant sulfonylureas (detemir group).CONCLUSIONSTreatment with EQW resulted in a significantly greater proportion of patients achieving target A1C and weight loss than treatment with detemir, with a low risk of hypoglycemia. These results suggest that EQW is a viable alternative to insulin detemir treatment in patients with type 2 diabetes with inadequate glycemic control using oral antidiabetes drugs.
Objectives Glucagon-like peptide-1 (GLP-1) receptor agonists have been used to treat type 2 diabetes for almost a decade, and new treatments in this class have recently been introduced. The purpose of this study was to examine perceptions of GLP-1 receptor agonists among physicians who treat patients with type 2 diabetes in the UK. Methods A total of 670 physicians (226 diabetes specialists; 444 general practice [GP] physicians) completed a survey in 2014. Results Almost all physicians had prescribed GLP-1 receptor agonists (95.4% total sample; 99.1% specialists; 93.5% GP), most frequently to patients whose glucose levels are not adequately controlled with oral medications (85.9% of physicians) and obese/overweight patients (83.7%). Physicians' most common reasons for prescribing a GLP-1 receptor agonist were: associated with weight loss (65.8%), good efficacy (55.7%), less hypoglycemia risk than insulin (55.2%), not associated with weight gain (34.5%), and better efficacy than oral medications (32.7%). Factors that most commonly cause hesitation when prescribing this class were: not considered first line therapy according to guidelines (56.9%), injectable administration (44.6%), cost (36.7%), gastrointestinal side effects (33.4%), and risk of pancreatitis (26.7%). Almost all specialists (99.1%) believed they had sufficient knowledge to prescribe a GLP-1 receptor agonist, compared with 76.1% of GPs. Conclusions Results highlight the widespread use of GLP-1 receptor agonists for treatment of type 2 diabetes in the UK. However, almost a quarter of GPs reported that they do not have enough knowledge to prescribe GLP-1s, suggesting a need for increased dissemination of information to targeted groups of physicians. Study limitations were that the generalizability of the clinician sample is unknown; survey questions required clinicians to select answers from multiple response options rather than generating the responses themselves; and responses to this survey conducted in 2014 do not reflect perceptions of the most recently introduced GLP-1 receptor agonists.
Glucagon-like peptide-1 (GLP-1)–based therapy improves glycaemic control through multiple mechanisms, with a low risk of hypoglycaemia and the additional benefit of clinically relevant weight loss. Since Starling and Bayliss first proposed the existence of intestinal secretions that stimulate the pancreas, tremendous progress has been made in the area of incretins. As a number of GLP-1 receptor agonists (GLP-1 RAs) continue to become available, physicians will soon face the challenge of selecting the right option customized to their patient's needs. The following discussion, derived from an extensive literature search using the PubMed database, applying the terms incretin, GLP-1, exenatide, liraglutide, albiglutide, dulaglutide, lixisenatide, semaglutide, and taspoglutide, provides a comprehensive review of existing and upcoming molecules in the GLP-1 RA class in terms of their structure, pharmacological profiles, efficacy, safety, and convenience. Search Methodology: A literature search was conducted using the PubMed database, applying the terms incretin, GLP-1, exenatide, liraglutide, albiglutide, dulaglutide, lixisenatide, semaglutide, and taspoglutide. Relevant articles were those that discussed structural, pharmacokinetic and pharmacodynamic differences, classification, long-acting and short-acting GLP-1 RAs, phase 3 trials, and expert opinions. Additional targeted searches were conducted on diabetes treatment guidelines and reviews on safety, as well as the American Diabetes Association/European Society for Study of Diabetes (ADA/EASD) statement on pancreatic safety.
