Abstract
Early and intensive management of type 2 diabetes has been shown to delay disease progression, reduce the risk of cardiorenal complications and prolong time to treatment failure. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are being increasingly recognized for their potential in early disease management, with recent guideline updates recommending second-line use of this injectable drug class alongside oral glucose-lowering drugs. GLP-1RAs target at least six of the eight core defects implicated in the pathogenesis of type 2 diabetes and offer significant glycaemic and weight-related improvements over other second-line agents in head-to-head trials. In addition, placebo-controlled clinical trials have shown cardiovascular protection with GLP-1RA use. Even so, this therapeutic class is underused in primary care, largely owing to clinical inertia and patient-related barriers to early intensification with GLP-1RAs. Fortunately, clinicians can overcome barriers to treatment acceptance through patient education and training, and management of treatment expectations. In this review we comment on global and Australian guideline updates and evidence in support of early intensification with this therapeutic class, and provide clinicians with practical advice for GLP-1RA use in primary care.

J Diabetes Complications 2020; 34:107575. [PMID: 32220551 DOI: 10.1016/j.jdiacomp.2020.107575] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2019] [Revised: 02/14/2020] [Accepted: 03/02/2020] [Indexed: 10/24/2022]
Abstract
AIMS To determine the early benefit:risk balance of dulaglutide versus insulin glargine in patients with type 2 diabetes mellitus (T2DM). METHODS This post hoc analysis used data from a randomized, open-label study (AWARD-2; modified intention-to-treat group) in which suboptimally controlled metformin + glimepiride-treated patients received dulaglutide 1.5 mg (n = 273) or insulin glargine (n = 262). Two composite endpoints were used: for weeks 2-20, fasting serum glucose (FSG) <130 mg/dL (<7.2 mmol/L) without hypoglycemia (blood glucose ≤70 mg/dL [≤3.9 mmol/L] or severe hypoglycemia); at week 26, patients with glycated hemoglobin (HbA1c) <7.0% (<53.0 mmol/mol) or reduction from baseline ≥1.0% (≥10.9 mmol/mol), no hypoglycemia (as defined above) and no weight gain. Odds ratios (ORs) were generated using logistic regression analysis. RESULTS The probability of reaching the FSG target without hypoglycemia was higher with dulaglutide than with insulin glargine at weeks 4 (OR 1.78; 95% confidence interval [CI] 1.22-2.60) and 8 (OR 1.69; 95% CI 1.15-2.48). The proportion of patients achieving the 26-week endpoint was higher with dulaglutide (37.4% vs. 10.3%; OR 5.28; 95% CI 3.28-8.48). CONCLUSIONS Dulaglutide's balanced efficacy-to-safety profile compares favorably with that of insulin glargine and is apparent soon after treatment initiation and after 6 months of therapy.

Dorzagliatin monotherapy in Chinese patients with type 2 diabetes: a dose-ranging, randomised, double-blind, placebo-controlled, phase 2 study. Lancet Diabetes Endocrinol 2018; 6:627-636.

Abstract
BACKGROUND Glucokinase acts as a glucose sensor in the pancreas and a glucose processor in the liver, and has a central role in glucose homoeostasis. Dorzagliatin is a new, dual-acting, allosteric glucokinase activator that targets both pancreatic and hepatic glucokinases. Dorzagliatin has good pharmacokinetic and pharmacodynamic properties in humans, and provides effective 24-h glycaemic control and improves glucose sensitivity in patients with type 2 diabetes. We aimed to assess the efficacy and safety of dorzagliatin monotherapy at different doses in Chinese patients with type 2 diabetes. METHODS In this multicentre, randomised, double-blind, placebo-controlled, phase 2 study, we randomly assigned (1:1:1:1:1) patients to receive oral placebo or one of four doses of oral dorzagliatin (75 mg once a day, 100 mg once a day, 50 mg twice a day, or 75 mg twice a day) using permuted-block randomisation, with a block size of ten and without stratification. Eligible patients were men or non-fertile women (aged 40-75 years) with type 2 diabetes who had a BMI of 19·0-30·0 kg/m2, were on a diet and exercise regimen, and were previously untreated or treated with metformin or α-glucosidase inhibitor monotherapy. The study started with a 4-week placebo run-in period followed by a 12-week treatment period. The primary endpoint was the change in HbA1c from baseline to week 12, which was assessed in all patients who received at least one dose of study drug and had both baseline and at least one post-baseline HbA1c value. Safety was assessed in all patients who received at least one dose of study drug. This study is registered with ClinicalTrials.gov, number NCT02561338. FINDINGS Between Sept 29, 2015, and Aug 17, 2016, we randomly assigned 258 patients to one of the five study groups. At the end of 12 weeks, the least squares mean change in HbA1c from baseline was -0·35% (95% CI -0·60 to -0·10) in the placebo group, -0·39% (-0·64 to -0·14) in the 75 mg once daily group, -0·65% (-0·92 to -0·38) in the 100 mg once daily group, -0·79% (-1·06 to -0·52) in the 50 mg twice daily group, and -1·12% (-1·39 to -0·86) in the 75 mg twice daily group. Compared with the placebo group, the change in HbA1c between baseline and 12 weeks was significant in the 50 mg twice daily (p=0·0104) and the 75 mg twice daily (p<0·0001) groups. The number of adverse events was similar between the treatment groups and the placebo group. There were no reports of drug-related serious adverse events or severe hypoglycaemia. INTERPRETATION Dorzagliatin had a beneficial effect on glycaemic control and was safe and well tolerated over 12 weeks in Chinese patients with type 2 diabetes.

Abstract
Assessment of the benefits of anti-diabetic drugs for type 2 diabetes requires analysis of composite end-points, taking HbA1c, bodyweight, hypoglycemia and other metabolic parameters into consideration; continuous, optimal glycemic control as well as bodyweight, blood pressure and lipid levels are critical to prevent micro- and macro-vascular complications. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are now established as an important total treatment strategy for type 2 diabetes, exerting glucose-lowering effects with little hypoglycemia risk and also ameliorating bodyweight, blood pressure and lipid levels, which are therapeutic targets for prevention of complications of the disease. The available data strongly suggest only beneficial effects of GLP-1RAs; however, long-term evaluation of the relevant composite end-points including health-related quality of life and cost-effectiveness remain to be investigated in adequately powered, prospective, controlled clinical trials. In the meantime, healthcare professionals need to be scrupulously attentive for potential, rare adverse events in patients using GLP-1RAs.
