Abstract
Objectives: There is no curative treatment for childhood obesity. We aim to synthesize published Randomized Controlled Trials (RCTs) evidence on the efficacy of exenatide in obese children and adolescents. Methods: We conducted a comprehensive search and analysis of relevant studies in popular databases such as PubMed, Web of Science, Embase, and Cochrane Library. Our focus was on RCTs that examined the effectiveness of exenatide for treating obesity in children. We primarily assessed changes in body weight, body mass index (BMI), fasting plasma glucose (FPG), or HbA1c levels. Additionally, we considered any adverse events reported during the treatment period, with particular attention to hypoglycemia. To evaluate the quality of RCTs included in our study, we employed the Cochrane bias assessment tool. Results: Five studies met the inclusion criteria. A group of 100 children were assigned to receive treatment with exenatide. Compared with controls, exenatide therapy reduced body weight and BMI by -0.6% (95% CI -0.93, -0.27), -1.11% (95% CI -1.91, -0.31), respectively. Undesirable consequences encompass gastrointestinal symptoms, with the majority of instances being characterized by mild severity. Conclusion: Exenatide demonstrates efficacy in the treatment of pediatric and adolescent obesity.

Abstract
Atherosclerosis is a chronic inflammatory disease characterized by lipid and inflammatory cell deposits in the inner layer of large- and medium-sized elastic and muscular arteries. Diabetes mellitus (DM) significantly increases the risk of cardiovascular diseases and the overall and cardiovascular mortality, and it is a pro-atherogenic factor that induces atherosclerosis development and/or accelerates its progression through a multifactorial process. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are a new class of drugs, belonging to the armamentarium to fight type 2 DM, that have shown robust reductions in atherosclerotic events and all-cause mortality in all studies. Preclinical studies have shown that GLP-1RAs play a role in the immunomodulation of atherosclerosis, affecting multiple pathways involved in plaque development and progression. In this review, we wanted to explore the translational power of such preclinical studies by analyzing the most recent clinical trials investigating the atheroprotective effect of GLP-1RAs.

Abstract
OBJECTIVES Patients with type 2 diabetes nowadays have a wide range of new antidiabetic medications with better efficacy and safety. Physicians' attitude toward selecting antidiabetic medications to reach targeted glycemic control and better quality of life (QOL) has not been studied prospectively. The global DISCOVER study aims to comprehensively provide a real-world assessment of the treatment pattern changes for patients with type 2 diabetes, in addition to QOL assessment. The Kingdom of Saudi Arabia was one of the countries participating in the DISCOVER study program. METHODS This study is a part of the prospective, longitudinal multinational DISCOVER study conducted in 38 countries including Saudi Arabia, a country facing an epidemic of type 2 diabetes, recruited 519 adult patients with type 2 diabetes with a mean age of 52.4 ± 11 years, where, they were followed up for three years period, where 477 patients completed the follow-up period. The clinical, biochemical, and patient lifestyle data were assessed periodically during the study period. DISCOVER study is registered with ClinicalTrials.gov identifiers: NCT02322762. RESULTS The most frequently used antidiabetic medications (ADMs) initially and during the follow-up were biguanides (metformin) and sulfonylureas (gliclazide, glibenclamide, glimepiride, glipizide, and glyclopyramide). Insulin (premix Insulin, basal insulin, and basal/bolus insulin) and dipeptidyl peptidase-4 (DPP-4) inhibitors (sitagliptin, vildagliptin, saxagliptin, and linagliptin) were the most frequent second and alternative of therapy. Other medications namely thiazolidinediones (TZds) (pioglitazone and rosiglitazone), incretins (exenatide and liraglutide), and Sodium-glucose co-transporter-2 (SGLT-2) inhibitors (canagliflozin) were used at a lesser rate. Drug availability, efficacy, and safety were the main determinants for choosing antidiabetic medications. The physical component score of the QOL had shown a significant decrease, while the mental component score has demonstrated an increase in QOL using SF36v2 Survey. CONCLUSIONS There is an increasing trend of using of newly available ADMs, mainly DPP-4 inhibitors. The major limitation of ADMs use is related to efficacy, availability, and safety. This warrant taking all the measures to overcome these limitations through adopting a multidisciplinary team approach for close monitoring of the patients and any unfavorable side effects. Additionally, global insurance coverage for all patients with type 2 diabetes could be a solution for the drug availability factor.

Abstract
Dipeptidyl peptidase 4 (DPP4) is a molecule implicated in the regulation of metabolic homeostasis and inflammatory processes, and it exerts its main action through its enzymatic activity. DPP4 represents the enzyme most involved in the catabolism of incretin hormones; thus, its activity impacts appetite, energy balance, and the fine regulation of glucose homeostasis. Indeed, DPP4 inhibitors represent a class of antidiabetic agents widely used for the treatment of Type 2 diabetes mellitus (T2DM). DPP4 also acts as an adipokine and is mainly secreted by the adipose tissue, mostly from mature adipocytes of the visceral compartment, where it exerts autocrine and paracrine activities. DPP4 can disrupt insulin signaling within the adipocyte and in other target cells and tissues, where it also favors the development of a proinflammatory environment. This is likely at the basis of the presence of elevated circulating DPP4 levels in several metabolic diseases. In this review, we summarize the most recent evidence of the role of the DPP4 as an adipokine-regulating glucose/insulin metabolism and fat homeostasis, with a particular focus on clinical outcomes associated with its increased secretion in the presence of adipose tissue accumulation and dysfunction.

Abstract
Glucagon-like peptide-1 receptor agonists and dipeptidyl peptidase-4 inhibitors are commonly used treatments for patients with type 2 diabetes mellitus (T2DM). Both anti-diabetic treatments function by playing key modulatory roles in the incretin system. Though these drugs have been deemed effective in treating T2DM, the Food and Drug Administration (FDA) and some members of the scientific community have questioned the safety of these therapeutics relative to important cardiovascular endpoints. As a result, since 2008, the FDA has required all new drugs for glycemic control in T2DM patients to demonstrate cardiovascular safety. The present review article strives to assess the safety and benefits of incretin-based therapy, a new class of antidiabetic drug, on the health of patient cardiovascular systems. In the process, this review will also provide a physiological overview of the incretin system and how key components function in T2DM.

Abstract
BACKGROUND Previous meta-analyses of the benefits and harms of glucagon-like peptide-1 receptor agonists (GLP1RAs) have been limited to specific outcomes and comparisons and often included short-term results. We aimed to estimate the longer-term effects of GLP1RAs on cardiovascular risk factors, microvascular and macrovascular complications, mortality, and adverse events in patients with type 2 diabetes, compared to placebo and other anti-hyperglycemic medications. METHODS We searched PubMed, Scopus, and clinicaltrials.gov (inception-July 2019) for randomized controlled trials ≥ 52 weeks' duration that compared a GLP1RA to placebo or other anti-hyperglycemic medication and included at least one outcome of interest. Outcomes included cardiovascular risk factors, microvascular and macrovascular complications, all-cause mortality, and treatment-related adverse events. We performed random effects meta-analyses to give summary estimates using weighted mean differences (MD) and pooled relative risks (RR). Risk of bias was assessed using the Cochrane Collaboration risk of bias in randomized trials tool. Quality of evidence was summarized using the Grading of Recommendations, Assessment, Development, and Evaluation approach. The study was registered a priori with PROSPERO (CRD42018090506). RESULTS Forty-five trials with a mean duration of 1.7 years comprising 71,517 patients were included. Compared to placebo, GLP1RAs reduced cardiovascular risk factors, microvascular complications (including renal events, RR 0.85, 0.80-0.90), macrovascular complications (including stroke, RR 0.86, 0.78-0.95), and mortality (RR 0.89, 0.84-0.94). Compared to other anti-hyperglycemic medications, GLP1RAs only reduced cardiovascular risk factors. Increased gastrointestinal events causing treatment discontinuation were observed in both comparisons. DISCUSSION GLP1RAs reduced cardiovascular risk factors and increased gastrointestinal events compared to placebo and other anti-hyperglycemic medications. GLP1RAs also reduced MACE, stroke, renal events, and mortality in comparisons with placebo; however, analyses were inconclusive for comparisons with other anti-hyperglycemic medications. Given the high costs of GLP1RAs, the lack of long-term evidence comparing GLP1RAs to other anti-hyperglycemic medications has significant policy and clinical practice implications.

Abstract
Patients with type 2 diabetes mellitus (T2DM) show an increased risk of cardiovascular diseases (CVD) and mortality. Many factors are implicated in the pathogenesis of CVD in patients with T2DM. Among the factors involved, chronic hyperglycemia and the cluster of CVD risk factors, such as dyslipidemia, hypertension, and obesity, play a major role. For many years, the control of hyperglycemia has been complicated by the fact that the use of many available drugs was associated with an increased risk of hypoglycemia. Paradoxically, hypoglycemia per se represents a risk factor for CVD. Recently, new drugs for the control of hyperglycemia have become available: many of them can determine a good control of hyperglycemia with minor risks of hypoglycemia. Among these new classes of drugs, glucagon-like peptide-1 receptor agonists (GLP-1RAs) offer many advantages. In addition to a strong anti-hyperglycemic action, they possess the ability to act on body weight and other relevant risk factors for CVD. Consistently, some of the GLP-1RAs have demonstrated, in RCT designed to assess their safety, to reduce the risk of major adverse cardiovascular events. Furthermore, GLP-1RAs possess properties useful to treat additional conditions, as the capability of improving liver damage in patients with NAFLD or NASH, highly prevalent conditions in people with T2DM. In this document, written by experts of the Italian diabetes society (SID), we will focus our attention on the therapy with GLP-1RAs in patients with T2DM, particularly on the effects on hyperglycemia, cardiovascular disease risk factors, NAFLD/NASH and CVD prevention.

Abstract
Glucagon-like peptide-1 receptor agonists (GLP-1RAs) and dipeptidyl peptidase-4 inhibitors (DPP4is) exert their effects via the incretin system, which augments glucose-dependent insulin secretion in response to nutrient intake (the 'incretin effect'). Both classes are well-established pharmacologic options for the management of glycemic control in individuals with type 2 diabetes (T2D) after failure of first-line metformin; however, they have inherent differences in their mechanisms of action that are reflected in their clinical safety and efficacy profiles. GLP-1RAs have high glycemic efficacy and are associated with weight loss and, in some cases, cardioprotective effects, with a side-effect profile of predominantly transient gastrointestinal adverse events. Most GLP-1RAs are administered as subcutaneous injection, although an oral formulation of one GLP-1RA, semaglutide, has recently become available. DPP4is provide moderate glycemic control, are weight-neutral, and do not offer any cardiovascular benefits, but are generally well tolerated. DPP4is are all administered orally. This narrative review aims to provide guidance for a primary care audience on the similarities and differences between GLP-1RA and DPP4i therapies, with a focus on their mechanism of action, clinical safety, efficacy, and real-world effectiveness. The role of incretin-based therapies in the T2D treatment paradigm, including key considerations for guiding treatment decisions, will also be discussed.

Abstract
Obesity is a chronic disease associated with many complications. Weight loss of 5-15% can improve many obesity-related complications. Despite the benefits of weight reduction, there are many challenges in losing weight and maintaining long-term weight loss. Pharmacotherapy can help people with obesity achieve and maintain their target weight loss, thereby reducing the risk of obesity-related complications. The prevalence of obesity in the USA has been increasing over the past few decades, and despite the availability of approved anti-obesity medications (AOMs), people with obesity may not be accessing or receiving treatment at levels consistent with the disease prevalence. Reasons for low levels of initiation and long-term use of AOMs may include reluctance of public health and medical organizations to recognize obesity as a disease, lack of reimbursement, provider inexperience, and misperceptions about the efficacy and safety of available treatments. This article aims to inform primary care providers about the mechanism of action of one class of AOMs, glucagon-like peptide 1 receptor agonists (GLP-1RAs), in weight loss and longer-term maintenance of weight loss, and the efficacy and safety of this treatment class. GLP-1RA therapy was initially developed to treat type 2 diabetes. Owing to their effectiveness in reducing body weight, once-daily subcutaneous administration of liraglutide 3.0 mg has been approved, and once-weekly subcutaneous administration of semaglutide 2.4 mg is being investigated in phase III trials, for obesity management. Considerations regarding adverse effects and contraindications for different drug classes are provided to help guide treatment decision-making when considering pharmacotherapy for weight management in patients with obesity.

Abstract
Pharmacological options for management of obesity and type 2 diabetes mellitus (T2DM) in children are limited. We aimed to synthesize published randomized controlled trial (RCT) evidence on the efficacy of glucagon-like peptide-1 (GLP-1) agonists in T2DM, pre-diabetes, and obesity in children aged <18 years. Inclusion criteria were RCTs of any GLP-1 agonist, solely or in conjunction with other drugs, for the treatment of obesity, pre-diabetes, and/or T2DM in children aged <18 years old. Nine studies met the inclusion criteria (two for T2DM, one for pre-diabetes, and six for obesity without diabetes). In total, 286 children were allocated to GLP-1 agonist therapy. Compared with controls, GLP-1 agonist therapy reduced HbA1c by -0.30% (95% confidence interval [CI] -0.57, -0.04) with a larger effect in children with (pre-)diabetes (-0.72%; 95% CI -1.17, -0.28; three studies) than in children with obesity (-0.08%; 95% CI -0.13, -0.02; four studies). Conversely, GLP-1 agonist therapy reduced body weight more in children with obesity (-2.74 kg; 95% CI -3.77, -1.70; six studies) than in children with T2DM (-0.97 kg; 95% CI -2.01, 0.08; two studies). Adverse effects included gastrointestinal symptoms and minor hypoglycemic episodes, but not severe hypoglycemia. GLP-1 agonists are efficacious in treating children with obesity and/or T2DM. Effect sizes are comparable with those reported in adults.

Abstract
The prevalence of obesity continues to grow rapidly worldwide, posing many public health challenges of the 21st century. Obese subjects are at major risk for serious diet-related noncommunicable diseases, including type 2 diabetes mellitus, cardiovascular disease, and non-alcoholic fatty liver disease. Understanding the mechanisms underlying obesity pathogenesis is needed for the development of effective treatment strategies. Dysregulation of incretin secretion and actions has been observed in obesity and related metabolic disorders; therefore, incretin-based therapies have been developed to provide new therapeutic options. Incretin mimetics present glucose-lowering properties, together with a reduction of appetite and food intake, resulting in weight loss. In this review, we describe the physiology of two known incretins—glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1), and their role in obesity and related cardiometabolic disorders. We also focus on the available and incoming incretin-based medications that can be used in the treatment of the above-mentioned conditions.

Abstract
The development of chronic kidney disease (CKD) in people with diabetes is commonplace, and is frequently associated with a significant and unfavourable impact on patient outcomes along with a substantial economic burden. With the development of novel classes of drug therapies in diabetes, there has been a recent focus on cardiovascular safety measures, with dedicated cardiovascular outcome trials (CVOTs) carried out for all new diabetes medications. More recently, there has been a growing regulatory view that such trials should report more specific renal outcomes to ensure simpler comparability between drugs and drug classes. This article explores some of the possible mechanisms by which these drugs may improve renal function in people with diabetes, and it reviews important CVOTs that have reported renal outcomes to date. These include CVOTS of sodium-glucose cotransporter-2 inhibitors (EMPA-REG OUTCOME study, CANVAS study, CREDENCE trial, DECLARE-TIMI trial and DAPA-HF study), dipeptidyl peptidase-4 inhibitors (EXAMINE trial, SAVOR-TIMI 53, TECOS trial and CARMELINA trial) and glucagon-like peptide-1 analogues (ELIXA trial, LEADER trial, SUSTAIN-6 trial, PIONEER-6 trial, EXSCEL trial, HARMONY Outcomes study and the REWIND study). Ongoing cardiovascular and renal outcome studies such as Dapa-CKD, EMPA-KIDNEY, EMPEROR-Preserved and EMPEROR-Reduced are also discussed. The heterogeneity of patient characteristics and reported renal outcomes, which hinders comparisons between trials and drug classes, is highlighted. Novel classes of diabetes therapies present an important opportunity for nephroprotection beyond the blockade of the renin-angiotensin-aldosterone system in this high-risk group. Clinicians should be aware of such benefits when prescribing these medications for people with, and possibly those without, type 2 diabetes.

Abstract
Objective: Evidence suggests that food preload improves postmeal glycemic profiles, but the effects of marine food are poorly understood. Our study aims to verify the regulating effects of premeal oyster meat (OM) on postprandial blood glucose.Method: Edible parts of the flesh of oyster were prepared for a randomized crossover experiment. After overnight fasting, 20 healthy young men consumed 300 mL of preload drinks with 0 g/kg body weight (BW) (control), 0.1 g/kg BW, and 0.2 g/kg BW. Peripheral blood concentrations of glucose and gastrointestinal hormones were measured before preloading at baseline (0 minutes) and at intervals after the preload and after a preset rice meal. The nutrient composition of OM was analyzed.Results: Compared with other doses, 0.2 g/kg BW OM preload induced higher plasma premeal insulin (p < 0.05), C-peptide (p < 0.05), and glucagon-like peptide-1 (GLP-1; p < 0.05) without altering the glucose concentrations during premeal times. By contrast, 0.2 g/kg BW OM induced less secretion of glucose (p < 0.05) and gastric inhibitory peptide (GIP; p < 0.05), but higher secretion of GLP-1 (p < 0.05) than 0.1 g/kg BW of OM after a meal. During the entire experiment (0-170 minutes), OM reduced the blood glucose (p < 0.05) and GIP (p < 0.05), but increased GLP-1 (p < 0.05). OM was rich in protein (78.4%) and low in fat (6%). Glutamic acid, aspartic acids, glycine, and taurine are the amino acids with high content found in OM.Conclusions: OM preload reduces postmeal glycemia in healthy young people with associated changes in gastrointestinal hormone responses. This effect may be attributed to the rich contents of protein and amino acids of OM.

Abstract
Gastrin and cholecystokinin (CCK) are classical gastrointestinal peptide hormones. Their biogenesis, structures, and intestinal secretory patterns are well-known with the striking feature that their receptor-bound 'active sites' are highly homologous and that this structure is conserved for more than 500 million years during evolution. Consequently, gastrin and CCK are agonists for the same receptor (the CCK2 receptor). But in addition, tyrosyl O-sulphated CCK are also bound to the specific CCK1 receptor. The receptors are widely expressed in the body, including pancreatic islet-cell membranes. Moreover, CCK and gastrin peptides are at various developmental stages and diseases expressed in pancreatic islets; also in human islets. Accordingly, bioactive gastrin and CCK peptides stimulate islet-cell growth as well as insulin and glucagon secretion. In view of their insulinotropic effects, gastrin and CCK peptides have come into focus as drug targets, either alone or in combination with other insulinotropic gut hormones or growth factors. So far, modified CCK and gastrin peptides are being examined as potential drugs for therapy of type 1 as well as type 2 diabetes mellitus.

Abstract
Background: Randomized and controlled trials of glucagon-like peptide-1 (GLP-1) derived drugs have shown that the most frequent adverse symptoms are gastrointestinal. Some of the side effects such as dyspepsia, nausea and upper abdominal pain may well be of gastric origin. Since the antral hormone gastrin regulates gastric secretion of acid and enzymes and contributes to the regulation of gastric motility, we examined the effect of GLP-1 on the secretion of gastrin in normal subjects and diabetes patients.Method: Plasma was sampled from ten healthy subjects and ten patients with diabetes mellitus type 1 with glucose clamped between 6 and 9 mM. GLP-1 or saline were infused for 4 h during and after a meal. Plasma concentrations of gastrin and GLP-1 were measured using specific radioimmunoassays.Results: Basal plasma concentrations of gastrin were similar in controls and patients. After the meal, the gastrin concentrations rose significantly during saline infusion, whereas the GLP-1 infusion suppressed the secretion of gastrin significantly, most pronounced in the diabetes patients.Conclusions: The results show that GLP-1 infusion suppresses the postprandial secretion of gastrin in normal subjects and even more so in the diabetes patients. The results may therefore shed further light on the upper gastrointestinal side effects of GLP-1-derived drugs in diabetic patients.

Abstract
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are well established as effective treatments for patients with type 2 diabetes. GLP-1 RAs augment insulin secretion and suppress glucagon release via the stimulation of GLP-1 receptors. Although all GLP-1 RAs share the same underlying mechanism of action, they differ in terms of formulations, administration, injection devices and dosages. With six GLP-1 RAs currently available in Europe (namely, immediate-release exenatide, lixisenatide, liraglutide; prolonged-release exenatide, dulaglutide and semaglutide), each with its own characteristics and administration requirements, physicians caring for patients in their routine practice face the challenge of being cognizant of all this information so they are able to select the agent that is most suitable for their patient and use it in an efficient and optimal way. The objective of this review is to bring together practical information on the use of these GLP-1 RAs that reflects their approved use.Funding: Eli Lilly and Company.Plain Language Summary: Plain language summary available for this article.

Abstract
Background: Diabetes is a very common cause of cardiovascular disease, and metformin remains the first-line treatment of diabetes. Many trials were conducted to prove the efficacy and safety of other antidiabetic medication as the best add-on medication. Objectives: We aimed to evaluate the atherosclerotic effect of incretin mimetics in patients with diabetes.Methods: We searched in PubMed, clinicaltrials.gov and Cochrane Library for randomized controlled trials (RCTs) comparing incretin mimetic with conventional treatment. The primary outcome was the change in carotid intima-media thickness (CIMT) at the end of the trials.Results: Five RCTs (n = 1241), the mean age of patients included in the trials is 64.3 ± 11.4. The primary outcome was statistically significant for CIMT improvement in terms of long-term follow-up analysis between the incretin mimetic group and conventional group (mean difference [MD] -0.031; 95% Confidence interval [CI] -0.049 to 0.012; P = 0.001), whereas at short-term follow-up it wasn't (MD -0.004; 95% CI -0.024 to 0.016; P = 0.7) in the overall group of study participants. Additionally, the mean change in body mass index (BMI) (MD 0.064; 95% CI -0.54 to 0.67; P = 0.8), and mean change in systolic blood pressure (MD -0.42; 95% CI -3.2 to 2.3; P = 0.8) or diastolic blood pressure (MD 0.25; 95% CI -1.18 to 1.68; P = 0.7) were not significant.Conclusion: Long-term use of incretin mimetic medication results in significant improvement of atherosclerosis, which leads to fewer vascular events, with no apparent effect on blood pressure or BMI. Further dedicated trials are required to show the superiority of adding these medications to conventional treatment versus placebo.

Abstract
OBJECTIVE Recent randomized and controlled trials of drugs derived from the gut hormone glucagon-like peptide-1 (GLP-1) show that the most frequent adverse symptoms are gastrointestinal, including gallbladder-related side effects such as cholithiasis and cholecystitis. Since the gut hormone cholecystokinin (CCK) stimulates bile secretion and regulates gallbladder motility and emptying, we examined the effect of GLP-1 on the secretion of CCK in normal subjects and patients with type 1 diabetes mellitus. MATERIALS AND METHODS Plasma was sampled from 10 healthy subjects and 10 patients with diabetes. With plasma glucose concentrations clamped between 6 and 9 nmol/l, GLP-1 or saline was infused for 240 min during and after a meal. The plasma concentrations of CCK were measured with a highly specific radioimmunoassay. RESULTS Basal plasma concentrations of CCK were similar in the normal subjects and in the diabetes patients. During the meal, the CCK concentrations rose significantly during saline infusion, whereas the GLP-1 infusion suppressed the secretion of CCK significantly in both normal subjects and in the diabetes patients. CONCLUSIONS The results show that GLP-1 suppresses the secretion of CCK after a meal in normal and diabetic subjects. The suppression attenuates the gallbladder contractility. Our data, therefore, offer an explanation for the increased risk of adverse gallbladder events during treatment with GLP-1-derived drugs.

Abstract
OJBECTIVE To explore temporal trends in antidiabetes drug (ADD) prescribing and intensification patterns, along with glycemic levels and comorbidities, and possible benefits of novel ADDs in delaying the need for insulin initiation in patients diagnosed with type 2 diabetes. RESEARCH DESIGN AND METHODS Patients with type 2 diabetes aged 18-80 years, who initiated any ADD, were selected (n = 1,023,340) from the U.S. Centricity Electronic Medical Records. Those who initiated second-line ADD after first-line metformin were identified (subcohort 1, n = 357,482); the third-line therapy choices were further explored. RESULTS From 2005 to 2016, first-line use increased for metformin (60-77%) and decreased for sulfonylureas (20-8%). During a mean follow-up of 3.4 years post metformin, 48% initiated a second ADD at a mean HbA1c of 8.4%. In subcohort 1, although sulfonylurea usage as second-line treatment decreased (60-46%), it remained the most popular second ADD choice. Use increased for insulin (7-17%) and dipeptidyl peptidase-4 inhibitors (DPP-4i) (0.4-21%). The rates of intensification with insulin and sulfonylureas did not decline over the last 10 years. The restricted mean time to insulin initiation was marginally longer in second-line DPP-4i (7.1 years) and in the glucagon-like peptide 1 receptor agonist group (6.6 years) compared with sulfonylurea (6.3 years, P < 0.05). CONCLUSIONS Most patients initiate second-line therapy at elevated HbA1c levels, with highly heterogeneous clinical characteristics across ADD classes. Despite the introduction of newer therapies, sulfonylureas remained the most popular second-line agent, and the rates of intensification with sulfonylureas and insulin remained consistent over time. The incretin-based therapies were associated with a small delay in the need for therapy intensification compared with sulfonylureas.
