The Five-Year Incidence of Progression to Osteoarthritis and Total Joint Arthroplasty in Patients Prescribed Glucagon-Like Peptide 1 Receptor Agonists. J Arthroplasty 2024; 39:2433-2439.e1. [PMID: 38857711 DOI: 10.1016/j.arth.2024.06.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2024] [Revised: 06/02/2024] [Accepted: 06/04/2024] [Indexed: 06/12/2024] Open
Abstract
BACKGROUND Research has suggested that glucagon-like peptide-1 receptor agonists (GLP-1-RAs) may have therapeutic effects on osteoarthritis of the hip and knee, in addition to managing diabetes and obesity. However, there is a lack of understanding regarding the association between GLP-1-RA use and the diagnosis of osteoarthritis (OA) of the hip and knee. METHODS A collaborative network analytics platform was queried for obese diabetic (n = 1,094,198), obese nondiabetic (n = 916,235), and nonobese diabetic (n = 157,305) patients who had an index visit between 2015 and 2017. Patients who had pre-existing hip and/or knee OA were excluded. A 1:1 propensity score matching was used to balance GLP-1-RA use in stratified cohorts for age, sex, race, body mass index, and hemoglobin A1c. The primary outcomes were rates of progression to hip OA, knee OA, major joint injections, total hip arthroplasty, and total knee arthroplasty. Cox proportional hazards models determined hazard ratios (HRs) between cohorts prescribed and not prescribed GLP-1-RAs. RESULTS All patients had a five-year follow-up. Rates of progression to hip and knee OA were higher among the GLP-1-RA users in both obese diabetic (hip HR: 1.63, 95% confidence interval [CI]: 1.46 to 1.82; knee HR: 1.52, CI: 1.41 to 1.64) and nonobese diabetic (hip HR: 1.78, CI: 1.50 to 2.10; knee HR: 1.58, CI: 1.39 to 1.80) cohorts. These diabetic cohorts received higher rates of major joint injections, though there was no difference in rates of total hip arthroplasty or total knee arthroplasty. No differences in five-year outcomes were seen when comparing obese, nondiabetic patients who were prescribed GLP-1-RAs with obese, nondiabetic patients not exposed to GLP-1-RAs. CONCLUSIONS This five-year analysis found a greater risk of progression to hip and knee OA among obese and non-obese diabetic GLP-1-RA users. Further studies should explore GLP-1-RA effects upon glucose management, weight loss, and lower extremity arthritis development. LEVEL OF EVIDENCE III, retrospective cohort study.

Lafferty RA, Flatt PR, Irwin N. NPYR modulation: Potential for the next major advance in obesity and type 2 diabetes management? Peptides 2024; 179:171256. [PMID: 38825012 DOI: 10.1016/j.peptides.2024.171256] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2024] [Revised: 05/13/2024] [Accepted: 05/30/2024] [Indexed: 06/04/2024]
Abstract
The approval of the glucagon-like peptide 1 (GLP-1) mimetics semaglutide and liraglutide for management of obesity, independent of type 2 diabetes (T2DM), has initiated a resurgence of interest in gut-hormone derived peptide therapies for the management of metabolic diseases, but side-effect profile is a concern for these medicines. However, the recent approval of tirzepatide for obesity and T2DM, a glucose-dependent insulinotropic polypeptide (GIP), GLP-1 receptor co-agonist peptide therapy, may provide a somewhat more tolerable option. Despite this, an increasing number of non-incretin alternative peptides are in development for obesity, and it stands to reason that other hormones will take to the limelight in the coming years, such as peptides from the neuropeptide Y family. This narrative review outlines the therapeutic promise of the neuropeptide Y family of peptides, comprising of the 36 amino acid polypeptides neuropeptide Y (NPY), peptide tyrosine-tyrosine (PYY) and pancreatic polypeptide (PP), as well as their derivatives. This family of peptides exerts a number of metabolically relevant effects such as appetite regulation and can influence pancreatic beta-cell survival. Although some of these actions still require full translation to the human setting, potential therapeutic application in obesity and type 2 diabetes is conceivable. However, like GLP-1 and GIP, the endogenous NPY, PYY and PP peptide forms are subject to rapid in vivo degradation and inactivation by the serine peptidase, dipeptidyl-peptidase 4 (DPP-4), and hence require structural modification to prolong circulating half-life. Numerous protective modification strategies are discussed in this regard herein, alongside related impact on biological activity profile and therapeutic promise.

Abstract
Despite the availability of a wide range of antihypertensive agents, a significant proportion of individuals with resistant hypertension (RHTN) struggle to achieve blood pressure (BP) control. Obesity ranks among the most significant modifiable risk factors for RHTN, with 56-91% of patients with RHTN classified as overweight or obese. Glucagon-like peptide-1 receptor agonist (GLP-1 RAs) are a class of anti-obesity medications that have recently demonstrated efficacy in reducing BP and improving cardiovascular (CV) outcomes in individuals with overweight or obesity. Among the available GLP-1-based therapies, liraglutide, semaglutide, and tirzepatide have been approved for chronic weight management in this population. Tirzepatide, a dual GLP-1 and glucose-dependent insulinotropic polypeptide receptor agonist, has the greatest effect on weight loss and BP reduction compared to GLP-1 RAs alone. To our knowledge, no trials have directly evaluated the effect of GLP-1 RAs or dual GLP-1/GIP receptor agonists on RHTN management. In this review article, we propose that targeting weight loss through GLP-1-based therapies should be explored as a treatment option for individuals with RHTN who are overweight or obese.

Adherence to glucagon-like peptide-1 receptor agonist treatment in type 2 diabetes mellitus: A nationwide registry study. Diabetes Obes Metab 2024. [PMID: 39215626 DOI: 10.1111/dom.15872] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2024] [Revised: 07/28/2024] [Accepted: 07/29/2024] [Indexed: 09/04/2024]
Abstract
AIMS To assess the level of adherence to glucagon-like peptide-1 receptor agonist (GLP-1RA) treatment using real-world data and to investigate the sociodemographic and clinical factors associated with discontinuation of GLP-1RAs. METHODS First-time users of GLP-1RAs with type 2 diabetes mellitus (T2DM), aged ≥18 years, in the period 2007 to 2020, were identified using Danish registries, allowing all participants a minimum of 18 months' follow-up. Adherence to GLP-1RA therapy (medication possession ratio >0.80) and discontinuation of GLP-1RA therapy was estimated at 6- and 12-month follow-ups. Multivariable cause-specific Cox regression was used to identify sociodemographic and clinical factors associated with risk of discontinuation. RESULTS In total, 44 343 first-time users of GLP-1RAs with T2DM were identified (mean age 58.6 years, 42.7% female, median duration of T2DM 6.8 years, median glycated haemoglobin level 65 mmol/mol). The absolute risk of discontinuing GLP-1RA treatment within 6 months was 14.2% (95% confidence interval [CI] 13.9-14.6) and 21.2% (95% CI 20.8-21.5) within 12 months. At 6 months, 50.4% were adherent to GLP-1RA therapy and at 12 months, 48.6% remained adherent. In the multivariable model, younger (<40 years) and older age (>75 years), higher Charlson Comorbidity Index score, lower household income, high school and longer university degree as educational attainment level, and longer diabetes duration were associated with a higher risk of discontinuing GLP-1RA treatment. CONCLUSION Approximately one in five patients discontinued GLP-1RA therapy within the first 12 months and only half were adherent. Overall, lower socioeconomic status and higher comorbidity burden were associated with higher risk of discontinuing GLP-1RA treatment.

Abstract
Glucagon-like peptide-1 receptor agonist (GLP-1RA) medications have been shown to be effective in achieving optimal glucose control and reducing all-cause death, cardiovascular death, nonfatal myocardial infarction, hospitalization for heart failure, and end-stage kidney disease in individuals with type 1 (T1D) and type 2 diabetes (T2D). However, use of these medications has been associated with increased hypoglycaemia risk in patients treated with concomitant antihyperglycaemic medications. The risk is particularly high in patients with T1D due to their loss of glucagon counter-regulatory response. This article reviews the effect of GLP-1RA formulations on the development of hypoglycaemia in individuals with T1D and T2D treated with insulin therapy, discusses the benefits of continuous glucose monitoring with GLP-1RA treatment, and presents strategies for safely initiating GLP-1RA therapy in these individuals.

Abstract
Adipose tissue (AT) represents a plastic organ that can undergo significant remodeling in response to metabolic demands. With its numerous checkpoints, the incretin system seems to play a significant role in controlling glucose homeostasis and energy balance. The importance of the incretin hormones, namely the glucagon-like peptide-1 (GLP-1) and the glucose-dependent insulinotropic peptide (GIP), in controlling the function of adipose cells has been brought to light by recent studies. Notably, a "paradigm shift" in reevaluating the role of the incretin system in AT as a potential target to treat obesity-linked metabolic disorders resulted from the demonstration that a disruption of the GIP and GLP-1 signaling axis in fat is associated with adiposity-induced insulin-resistance (IR) and/or type 2 diabetes mellitus (T2D). We will briefly discuss the (patho)physiological functions of GLP-1 and GIP signaling in AT in this review, emphasizing their potential impacts on lipid storage, adipogenesis, glucose metabolism and inflammation. We will also address the conundrum with the perturbation of the incretin axis in white or brown fat tissue and the emergence of metabolic disorders. In order to reduce or avoid adiposity-related metabolic complications, we will finally go over a potential scientific rationale for suggesting AT as a novel target for GLP-1 and GIP receptor agonists and co-agonists.

Abstract
Novel antiobesity medications, particularly glucagon-like peptide-1 receptor agonists (GLP-1RAs), have expanded weight loss (WL) options for kidney transplantation (KT) candidates with obesity beyond lifestyle modifications and bariatric surgery. However, varying effectiveness, risk profiles, and costs make strategy choices challenging. To aid decision-making, we used a Markov model to examine the cost-effectiveness of different WL strategies over a 10-year horizon. A target WL of 15% of total body weight was used for the base case scenario, and we compared these strategies to a "liberal" KT strategy of transplanting candidates with obesity. Outcomes included costs (2023 US dollars), quality-adjusted life years, and incremental cost-effectiveness ratios. In analysis, a liberal KT strategy was favored over lifestyle modifications and GLP-1RAs. Among WL strategies, bariatric surgery was the most effective and cost the least, whereas lifestyle modification had the highest cumulative costs and was the least effective. Compared to liberal KT, bariatric surgery costs $45 859 per quality-adjusted life year gained. GLP-1RAs were favored over bariatric surgery only when drug costs were below $5000 per year (base cost $12 077). In conclusion, for KT candidates with obesity, a liberal KT strategy and bariatric surgery are preferred over lifestyle modifications alone and GLP-1RAs based on outcomes and cost-effectiveness.

Abstract
The growing prevalence of type 2 diabetes (T2D) remains a leading health concern in the US. Despite new medications and technologies, glycemic control in this population remains suboptimal, which increases the risk of poor outcomes, increased healthcare resource utilization, and associated costs. This article reviews the clinical and economic impacts of suboptimal glycemic control in patients on basal-bolus insulin or multiple daily injections (MDI) and discusses how new technologies, such as tubeless insulin delivery devices, referred to as "patch pumps", have the potential to improve outcomes in patients with T2D.

Abstract
INTRODUCTION The efficacy of non-pharmacotherapeutic treatment of obstructive sleep apnea, a highly prevalent condition with serious cardiometabolic and neurocognitive health consequences, is well established. Supplementing traditional treatment strategies with medications can improve symptoms and reduce side effects. Efforts to identify medications that target the causes of sleep apnea have met with mixed success. However, this remains a worthwhile objective for researchers to pursue, given the potential benefit pharmacotherapy could bring to those patients who reject or struggle to adhere to existing treatments. AREAS COVERED This article presents the case for obstructive sleep apnea pharmacotherapy including drugs that reduce the occurrence of apnea events, such as weight loss agents, ventilation activators and muscle and nervous system stimulants, drugs that alleviate symptoms, such as wake-promoting agents for excessive daytime sleepiness, and drugs that improve adherence to existing treatments, such as hypnotics. Literature was accessed from PubMed between 1 March 2024 and 18 April 2024. EXPERT OPINION Exciting recent advances in both our understanding of obstructive sleep apnea pathology and in the techniques used to identify therapeutic agents and their targets combine to embolden a positive outlook for the expanded use of drugs in tackling this consequential disease.

Abstract
Background and Aim: Glucagon-like peptide-1 receptor agonists (GLP-1 RA) therapy provides glycemic benefits to individuals with type 2 diabetes (T2D). However, the effects of GLP-1 RA therapy in combination with FreeStyle Libre systems (FSL) are unknown. This study aimed to compare changes in hemoglobin A1c (HbA1c) between people acquiring GLP-1 with FSL (GLP-1+FSL) versus GLP-1 without FSL (GLP-1). Methods: This real-world study used Optum's de-identified Market Clarity Data, a linked electronic health records (EHR)-claims database, and included adults with T2D and HbA1c ≥8% who acquired their first GLP-1 RA medication between 2018 and 2022. GLP-1+FSL subjects acquired their first FSL within ±30 days of their first GLP-1 acquisition. Cohorts were matched 1:5 on baseline insulin therapy, age, sex, baseline HbA1c, and GLP-1 type. Paired changes in HbA1c were compared between unmatched and matched groups at 6 months. Results: The study included 24,724 adults in the unmatched cohort (GLP-1+FSL, n = 478; GLP-1, n = 24,246). The matched cohort included 478 GLP-1+FSL users and 2,390 GLP-1 users: mean age 53.5 ± 11.8 and 53.5 ± 11.3 years, HbA1c 10.25 ± 1.68% and 10.22 ± 1.69%, respectively. HbA1c reduction was greater in the GLP-1+FSL group compared with the GLP-1 group in the unmatched cohort (-2.43% vs. -1.73%, difference 0.70%, P < 0.001, respectively) and in the matched cohort (-2.43% vs. -2.06%, difference 0.37%, P < 0.001). GLP-1+FSL vs. GLP-1 treatment was associated with greater HbA1c reduction in the intensive insulin (-2.32% vs. -1.50%), nonintensive insulin (-2.50% vs. -1.74%), and noninsulin group (-2.46% vs. -1.78%), as well as in patients using semaglutide (-2.73% vs. -1.92%) and dulaglutide (-2.45% vs. -1.71%) GLP-1 RA, all P < 0.001. Conclusions: Adults with suboptimally controlled T2D, initiating GLP-1 RA with FreeStyle Libre, had greater improvement in HbA1c compared with those treated with GLP-1 RA only. These results suggest an additional glycemic benefit of FSL when used with a GLP-1 RA in T2D treatment.

Abstract
Early initiation of intensive insulin therapy has been demonstrated to be effective in controlling glycemia and possibly preserving beta-cell function. Innovations in insulin formulations and delivery systems continue. However, we have seen an acceleration in the development of new classes of diabetes medications for individuals with type 2 diabetes and obesity, such as, for example, glucagon-like peptide-1 receptor agonists (GLP-1 RAs). These formulations have been shown to confer significant benefits in achieving good glycemic control with reduced hypoglycemia risk, weight loss, and cardiorenal protection. Therefore, it is reasonable to question whether there is still a role for insulin therapy in the management of type 2 diabetes. However, there are clear limitations inherent to GLP-1 RA therapy, including high rates of suboptimal adherence and treatment discontinuation due to high cost and side effects, which diminish long-term efficacy, and supply issues. In addition, newer formulations have shown improvements in convenience and tolerability, and have been shown to be even more effective when used in conjunction with basal insulin. In this narrative review, we discuss current evidence that supports GLP-1 RA use in combination with insulin therapy and the potential pitfalls of reliance on GLP-1 RAs as a substitute for insulin therapy.

Abstract
The burden of chronic metabolic diseases such as obesity, type 2 diabetes mellitus (T2DM), and metabolic dysfunction-associated steatotic liver disease (MASLD) and the urgency of the epidemiological situation necessitate the development of therapies that enhance metabolic health and alter the trajectory of metabolic disease in society. Certain bariatric-metabolic surgeries have proven to be effective approaches for treating metabolic dysfunction, showing remission or significant improvements in obesity, T2DM, and MASLD-related outcomes, suggesting that these interventions might be able to "reset" a pathologically calibrated metabolic setpoint. However, considering the challenges and invasiveness of surgery, endoscopic bariatric metabolic therapies (EBMTs) have emerged with a primary focus to reconstruct or mimic anatomical and/or functional changes observed with bariatric surgery in a more broadly accessible manner. These innovative approaches offer a potentially promising solution to address significant unmet medical need in the large segment of society, which remains at risk for the consequences of metabolic diseases. In this review, we discuss therapeutic options within the EBMT space in the context of the metabolic setpoint intellectual model and provide a brief overview of current knowledge surrounding their mechanisms of action and impact on metabolic health. Finally, we explore future perspectives and directions in this exciting field.

Abstract
Despite the advent of innovative therapies in the treatment of diabetes, ever-increasing awareness is still directed to the role of insulin since it has continued to be at the centre of diabetes therapy for decades, as a therapeutic integration of innovative agents in type 2 diabetes mellitus (T2DM), as the only replacement therapy in type 1 diabetes mellitus (T1DM) and also in gestational diabetes. In this context, the study of molecules such as weekly basal insulins, both for their technological and pharmacodynamic innovation and their manageability and undoubted benefits in compliance with drug therapy, can only be a turning point in diabetes and for all its phenotypes. This review aims to provide insight into the knowledge of basal weekly insulins and their use in type 1 and 2 diabetes mellitus by examining their safety, efficacy, manageability and increased therapeutic compliance.

Abstract
Since its first use just over a century ago, insulin treatment has evolved dramatically, such that the molecules are physiologic in nature, and treatment can now closely resemble the natural hormone response over 24 hours. Newer, longer-acting basal insulin analogs have provided insulin therapies with improved characteristics and, therefore, ease of use, and can readily be incorporated as part of routine treatment for type 2 diabetes (T2D), but evidence suggests that insulin remains underused in people with T2D. We review the barriers to initiation of basal insulin and the education needed to address these barriers, and we provide practical pointers, supported by evidence, for primary care physicians and advanced practice providers to facilitate timely initiation of basal insulin in the people with T2D who will benefit from such treatment.

Abstract
AIM To assess the safety, tolerability, pharmacokinetics (PKs) and pharmacodynamics of HRS-7535, a novel glucagon-like peptide-1 receptor agonist (GLP-1RA), in healthy participants. MATERIALS AND METHODS This phase 1 trial consisted of single-ascending dose (SAD), food effect (FE) and multiple-ascending dose (MAD) parts. In the SAD part, participants were randomized (6:2) to receive HRS-7535 (at doses of 15, 60 and 120 mg; administered orally once daily) or placebo. In the FE part, participants were randomized (8:2) to receive a single dose of 90-mg HRS-7535 or placebo, in both fed and fasted states. In the MAD part, participants were randomized (18:6) to receive daily HRS-7535 (120 mg [30/60/90/120-mg titration scheme]) or placebo for 28 days. The primary endpoints were safety and tolerability. RESULTS Nausea and vomiting were the most frequently reported AEs across all three parts. In the SAD part, the median Tmax was 5.98-5.99 hours and the geometric mean t1/2 was 5.28-9.08 hours across the HRS-7535 dosing range. In the MAD part, the median Tmax was 5.98-10.98 hours and the geometric mean t1/2 was 6.48-8.42 hours on day 28 in participants on HRS-7535. PKs were approximately dose-proportional. On day 29 in the MAD part, the mean (percentage) reduction in body weight from baseline was 4.38 kg (6.63%) for participants who received HRS-7535, compared with 0.8 kg (1.18%) for those participants who received a placebo. CONCLUSIONS HRS-7535 exhibited a safety and tolerability profile consistent with other GLP-1RAs and showed PKs suitable for once-daily dosing. These findings support further clinical development of HRS-7535 for type 2 diabetes.

Abstract
Adherence to the treatment of type 2 diabetes (T2D), which includes the use of prescribed drugs, following a healthy diet, and adopting a physically active lifestyle, is important to control the disease and improve the patients' quality of life. The present study aimed to explain the determinants of adherence to treatment in patients with T2D based on Pender's Health Promotion Model (HPM). The present research used a qualitative content analysis and was based on Pender's HPM. The data were collected through in-depth semi-structured interviews with 20 T2D patients using a purposive sampling in Bandar Abbas, southern Iran. Maximum variation was considered in terms of gender, age, history of diabetes, type of drug used, education, and occupation. The data collection continued until data saturation. At the same time, the collected data were analyzed using the directed content analysis. MAXQDA 10 was used to manage codes and facilitate data analysis. The data analysis led to the extraction of 10 categories and 19 subcategories as the determinants of adherence to the treatment of T2D patients. The participants shared their experiences about personal characteristics and their ecological environment, specific cognition and emotions, and the behavioral results and experience as the determinants of adherence to T2D treatment. The categories extracted from this study in the form of HPM constructs provided a framework to explain treatment adherence. This information can help policy makers and planners in designing future programs.

Abstract
In recent years, we have witnessed the many beneficial effects of glucagon-like peptide (GLP)-1 receptor agonists, including the reduction in cardiovascular risk in patients with type 2 diabetes, and the reduction of body weight in those with obesity. Increasing evidence suggests that these agents differ considerably from endogenous GLP-1 when it comes to their routes of action, although their clinical effects appear to be the same. Given the limitations of the GLP-1 receptor agonists, could it be useful to develop agents which stimulate GLP-1 release? Here we will discuss the differences and similarities between GLP-1 receptor agonists and endogenous GLP-1, and will detail how endogenous GLP-1-when stimulated appropriately-could have clinically relevant effects.

Abstract
Type 2 diabetes (T2D) in youth is a global health concern characterized by an increasing incidence and prevalence, especially among disadvantaged socioeconomic subgroups. Moreover, youth-onset T2D is more aggressive and causes earlier, more severe long-term cardio-renal complications compared with T2D in adults. The therapeutic options available are limited and often inadequate, partially due to the numerous challenges in implementing clinical trials for this vulnerable patient population. Over the last few years, a significant effort has been made to develop new effective drugs for children and adolescents with T2D. Specifically, a number of studies are currently generating new data to address the urgent unmet medical need for optimal management of this disease. This review describes the central features of youth-onset T2D and summarizes the available treatments and ongoing studies in pediatric patients.

Abstract
Neurological disorders and type 2 diabetes mellitus (T2DM) are deeply intertwined. For example, autonomic neuropathy contributes to the development of T2DM and continued unmanaged T2DM causes further progression of nerve damage. Increasing glycemic control has been shown to prevent the onset and progression of diabetic autonomic neuropathies. Neuromodulation consisting of combined stimulation of celiac vagal fibers innervating the pancreas with concurrent electrical blockade of neuronal hepatic vagal fibers innervating the liver has been shown to increase glycemic control in animal models of T2DM. The present study demonstrated that the neuromodulation reversed glucose intolerance in alloxan-treated swine in both pre- and overt stages of T2DM. This was demonstrated by improved performance on oral glucose tolerance tests (OGTTs), as assessed by area under the curve (AUC). In prediabetic swine (fasting plasma glucose (FPG) range: 101-119 mg/dL) the median AUC decreased from 31.9 AUs (IQR = 28.6, 35.5) to 15.9 AUs (IQR = 15.1, 18.3) p = 0.004. In diabetic swine (FPG range: 133-207 mg/dL) the median AUC decreased from 54.2 AUs (IQR = 41.5, 56.6) to 16.0 AUs (IQR = 15.4, 21.5) p = 0.003. This neuromodulation technique may offer a new treatment for T2DM and reverse glycemic dysregulation at multiple states of T2DM involved in diabetic neuropathy including at its development and during progression.

Abstract
INTRODUCTION Atherosclerotic cardiovascular disease (ASCVD) and heart failure (HF) are two major complications of type 2 diabetes (T2DM). Cardiovascular protection is a key objective, yet not fully reached in clinical practice. AREAS COVERED Both glucagon-like peptide-1 receptor agonists (GLP-1RAs) and sodium-glucose cotransporter 2 inhibitors (SGLT2is) have proven their efficacy in reducing major cardiovascular events in high-risk patients with T2DM and SGLT2is in reducing hospitalization for HF in placebo-controlled randomized trials. However, real-life studies worldwide revealed that only a minority of patients with T2DM receive either a GLP-1RA or an SGLT2i and surprisingly even less patients with established ASCVD or HF are treated with these cardioprotective antihyperglycemic agents. EXPERT OPINION Bridging the gap between evidence-based cardiovascular protection with GLP-1RAs and SGLT2is and their underuse in daily clinical practice in patients with T2DM at high risk is crucial from a public health viewpoint. However, the task appears hazardous and the goal not attained considering the current failure. Education of specialists/primary care physicians and patients is critical. Multifaceted and coordinated interventions involving all actors (physicians, patients and broadly health-care system) must be implemented to stimulate the adoption of these cardioprotective antihyperglycemic medications as part of routine cardiovascular care among patients with T2DM.

Abstract
BACKGROUND Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have shown cardiovascular benefits in cardiovascular outcome trials in type 2 diabetes mellitus. However, the most convincing evidence was obtained in subjects with established cardiovascular (CV) disease. We analyzed the determinants of GLP-1 RA-mediated CV protection in a real-world population of persons with type 2 diabetes with and without a history of CV events with long-term follow-up. METHODS Retrospective cohort study of 550 individuals with type 2 diabetes (395 in primary CV prevention, 155 in secondary CV prevention), followed at a single center after the first prescription of a GLP-1 RA between 2009 and 2019. CV and metabolic outcomes were assessed. RESULTS Median duration of follow-up was 5.0 years (0.25-10.8) in primary prevention and 3.6 years (0-10.3) in secondary prevention, with a median duration of treatment of 3.2 years (0-10.8) and 2.5 years (0-10.3) respectively. In the multivariable Cox regression model considering GLP-1 RA treatment as a time-dependent covariate, in the primary prevention group, changes in BMI and glycated hemoglobin did not have an impact on MACE risk, while age at the time of GLP-1 initiation (HR 1.08, 95% CI 1.03-1.14, p = 0.001) and GLP-1 RA cessation by time (HR 3.40, 95% CI 1.82-6.32, p < 0.001) increased the risk of MACE. Regarding the secondary prevention group, only GLP-1 RA cessation by time (HR 2.71, 95% CI 1.46-5.01, p = 0.002) increased the risk of MACE. With respect to those who withdrew treatment, subjects who continued the GLP-1 RA had significantly greater weight loss and lower glycated hemoglobin levels during follow-up. CONCLUSIONS In this real-world type 2 diabetes population, discontinuation of GLP-1 RA treatment was associated to a higher risk of major cardiovascular events, in both subjects with and without a history of CV events.

Abstract
INTRODUCTION : Obesity is recognised as a major healthcare challenge. Following years of slow progress in discovery of safe, effective therapies for weight management, recent approval of the glucagon-like peptide 1 receptor (GLP-1R) mimetics, liraglutide and semaglutide, for obesity has generated considerable excitement. It is anticipated these agents will pave the way for application of tirzepatide, a highly effective glucose-dependent insulinotropic polypeptide receptor (GIPR), GLP-1R co-agonist recently approved for management of type 2 diabetes mellitus. AREAS COVERED : Following promising weight loss in obese individuals in Phase III clinical trials, liraglutide and semaglutide were approved for weight management without diabetes. Tirzepatide has attained Fast Track designation for obesity management by the US Food and Drug Association. This narrative review summarises experimental, preclinical and clinical data for these agents and related GLP-1R/GIPR co-agonists, prioritising clinical research published within the last 10 years where possible. EXPERT OPINION : GLP-1R mimetics are often discontinued within 24-months, owing to gastrointestinal side-effects, meaning long-term application of these agents in obesity is questioned. Combined GIPR/GLP-1R agonism appears to induce fewer side-effects, indicating GLP-1R/GIPR co-agonists may be more suitable for enduring obesity management. After years of debate, this GIPR-biased GLP-1R/GIPR co-agonist highlights the therapeutic promise of including GIPR modulation for diabetes and obesity therapy.

Abstract
AIMS To determine the extent of therapeutic inertia related to the weekly injectable glucagon-like peptide-1 receptor agonists dulaglutide and semaglutide in patients with type 2 diabetes (T2D) in the United Kingdom. MATERIALS AND METHODS Adults with T2D who received their first primary care prescription of dulaglutide or semaglutide between January and July 2019 were identified from the UK Clinical Practice Research Datalink GOLD primary care database. Doses prescribed, glycated haemoglobin (HbA1c), body mass index (BMI) and concomitant T2D medications were assessed at first prescription and at 3, 6 and 9 months. RESULTS Of the patients prescribed dulaglutide (N = 748; mean [SD] age 59.0 [11.2] years) and semaglutide (N = 437; mean [SD] age 58.4 [10.6] years), 93.0% and 89.0%, respectively, had an HbA1c level ≥7.5% (≥58.46 mmol/mol), and 56.4% and 54.9%, respectively, had an HbA1c level ≥9.0% (≥74.86 mmol/mol), at first prescription. At 6 to 9 months, 75.0% of those on dulaglutide 0.75 mg and 57.6% of those on semaglutide 0.25 mg or 0.5 mg had an HbA1c level ≥7.5% (≥58.46 mmol/mol). At 9 months, 21.9% of the dulaglutide cohort were on the suboptimal dose of 0.75 mg, and 46.1% of the semaglutide cohort were on the suboptimal doses of 0.25 mg or 0.5 mg. CONCLUSIONS Multiple examples of therapeutic inertia were identified, including first prescription at HbA1c levels considerably above target and failure to escalate to optimal doses even with evidence of suboptimal metabolic control. A substantial proportion of patients therefore did not achieve optimal HbA1c targets.

Abstract
The metabolic syndrome as a consequence of the obesity pandemic resulted in a substantial increase in the prevalence of metabolic-associated fatty live disease (MAFLD) and type 2 diabetes mellitus (T2DM). Because of the similarity in pathobiology shared between T2DM and MAFLD, both disorders coexist in many patients and may potentiate the disease-related outcomes with rapid progression and increased complications of the individual diseases. In fact, awareness about this coexistence and the risk of complications are often overlooked by both hepatologists and diabetologists. Management of these individual disorders in a patient should be addressed wholistically using an appropriate multidisciplinary team approach involving both the specialists and, when necessary, liaising with dieticians and surgeons. This comprehensive review is to compile the current evidence from a diabetologist's perspective on MAFLD and T2DM and to suggest optimal management strategies.

Abstract
GPR40 is a class A G-protein coupled receptor (GPCR) mainly expressed in pancreas, intestine, and brain. Its endogenous ligand is long-chain fatty acids, which activate GPR40 after meal ingestion to induce secretion of incretins in the gut, including GLP-1, GIP, and PYY, the latter control appetite and glucose metabolism. For its involvement in satiety regulation and metabolic homeostasis, partial and AgoPAM (Positive Allosteric Modulation agonist) GPR40 agonists had been developed for type 2 diabetes (T2D) by many pharmaceutical companies. The proof-of-concept of GPR40 for control of hyperglycemia was achieved by clinical trials of partial GPR40 agonist, TAK-875, demonstrating a robust decrease in HbA1c (-1.12%) after chronic treatment in T2D. The development of TAK-875, however, was terminated due to liver toxicity in 2.7% patients with more than 3-fold increase of ALT in phase II and III clinical trials. Different mechanisms had since been proposed to explain the drug-induced liver injury, including acyl glucuronidation, inhibition of mitochondrial respiration and hepatobiliary transporters, ROS generation, etc. In addition, activation of GPR40 by AgoPAM agonists in pancreas was also linked to β-cell damage in rats. Notwithstanding the multiple safety concerns on the development of small-molecule GPR40 agonists for T2D, some partial and AgoPAM GPR40 agonists are still under clinical development. Here we review the most recent progress of GPR40 agonists development and the possible mechanisms of the side effects in different organs, and discuss the possibility of developing novel strategies that retain the robust efficacy of GPR40 agonists for metabolic disorders while avoid toxicities caused by off-target and on-target mechanisms.

Abstract
Background Depression and obesity have a bidirectional relationship making the management of one, without the other, problematic. Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are a preferred medication class for diabetes and obesity treatment given their weight loss effect; however, it is not known how antidepressants impact this effect. Objective To assess the impact of antidepressant use on GLP-1 RA-associated weight loss in patients with or without type 2 diabetes mellitus. Methods This was a retrospective, propensity matched, cohort study conducted using TriNetX. The study identified patients initiating a GLP-1 RA being treated with citalopram/escitalopram, bupropion, or no antidepressant. Cohorts were propensity score matched to analyze the primary outcome of mean end-of-study (77-371 days) body weight. Results An initial query identified 31 273 patients eligible for analysis (30 160 receiving no antidepressant, 311 receiving bupropion, and 802 receiving citalopram/escitalopram). After propensity score matching, the study found patients receiving citalopram/escitalopram were taking more antidiabetic therapies at baseline compared with patients not treated with an antidepressant. Patients in the antidepressant cohorts experienced less weight loss compared with their respective matched cohorts not receiving antidepressants (citalopram/escitalopram -0.73 kg versus -1.74 kg; bupropion -0.84 kg versus -3.46 kg). Only the bupropion cohort was significantly heavier at end-of-study versus the non-antidepressant cohort (108 kg versus 103 kg, P = 0.018). Conclusion and Relevance Antidepressants may diminish the weight loss effect of GLP-1 RAs. Additional research is needed to assess whether all GLP-1 RAs are affected similarly and the optimal weight loss strategies in patients receiving antidiabetic therapy with comorbid depression.

Contemp Clin Trials Commun 2022; 28:100944. [PMID: 35812819 PMCID: PMC9260263 DOI: 10.1016/j.conctc.2022.100944] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2021] [Revised: 05/26/2022] [Accepted: 06/07/2022] [Indexed: 01/16/2023] Open
Abstract
Aim Semaglutide is a long-acting glucagon-like peptide-1 receptor agonist (GLP-1 RA) indicated for glycaemic management in adults with type 2 diabetes (T2D). Oral semaglutide administration can help decrease glycated haemoglobin (HbA1c) and body weight in people with uncontrolled T2D. We evaluated the efficacy and safety of oral semaglutide compared to that of subcutaneous semaglutide, placebo, and other GLP-1 RAs in the treatment of T2D. Methods Randomised controlled trials of subcutaneous and oral semaglutide for glycaemic control in adults with T2D were selected from the Cochrane Central Register of Controlled Trials and PubMed. Mean differences (MDs) and risk ratios with 95% confidence intervals (CIs) were used to synthesise the results, and oral and subcutaneous semaglutide formulations were indirectly compared using mixed treatment comparisons. Results Twelve studies were included in this review (6840 participants). Oral semaglutide (14.0 mg) significantly reduced HbA1c (MD, −1.30% [95%CI: -1.44, −1.16], P < 0.05) and body weight (MD, −3.17 kg [95%CI: -3.89, −2.45], P < 0.05) compared to placebo (MD, HbA1c: -0.32% [95%CI: -0.49, −0.15], P < 0.05; MD body weight: -2.56 kg [95%CI: -3.41, −1.71], P < 0.05), liraglutide (1.2 mg), exenatide ER (2.0 mg), and dulaglutide (1.5 mg). Oral semaglutide was slightly less effective than subcutaneous semaglutide in reducing HbA1c levels (MD: -0.26% [95%CI: -0.44, −0.07], P < 0.05) and body weight (MD: -1.08 kg [95%CI: -2.04, −0.12], P < 0.05). Oral semaglutide increased the incidence of adverse events (nausea, diarrhoea, dyspepsia, and vomiting) compared to placebo, liraglutide (1.2 mg), exenatide (ER, 2.0 mg), and dulaglutide 1.5 mg but not compared to subcutaneous semaglutide. Conclusion Oral semaglutide was non-inferior to subcutaneous semaglutide and superior to placebo and another GLP-1 RA in reducing HbA1c and body weight. It was superior to subcutaneous semaglutide and inferior to other GLP-1 RA comparators and placebo in terms of the incidence of adverse events. Thus, oral semaglutide provides a convenient administration route for patients who prefer oral treatments over injectable therapies.

Abstract
The available data suggest differences in the course of type 2 diabetes mellitus (T2DM) between men and women, influenced by the distinguishing features of the sex. Glucagon-like peptide 1 receptor agonists (GLP-1 RAs) are a relatively new class of antidiabetic drugs that act by mimicking the function of endogenous glucagon-like peptide 1. They constitute valuable agents for the management of T2DM as, in addition to exerting a strong hypoglycemic action, they present cardiorenal protective properties, promote weight loss, and have a good safety profile, particularly with respect to the risk of hypoglycemia. Due to the precedent of studies having identified sexual dimorphic elements regarding the action of other antidiabetic agents, ongoing research has attempted to examine whether this is also the case for GLP-1 RAs. Until now, sex differences have been observed in the impact of GLP1-RAs on glycemic control, weight reduction, and frequency of adverse events. On the contrary, the question of whether these drugs differentially affect the two sexes with respect to cardiovascular risk and incidence of major adverse cardiovascular events remains under investigation. Knowledge of the potential sex-specific effects of these medications is extremely useful for the implementation of individualized therapeutic plans in the treatment of T2DM. This narrative review aims to present the available data regarding the sex-specific action of GLP-1 RAs as well as to discuss the potential pathophysiologic mechanisms explaining these dissimilarities.

Abstract
PURPOSE Type 2 diabetes (T2D) medication adherence is poor and is impacted by individual drug characteristics. Treatment-associated weight change can affect medication-taking behavior. This review aimed to explore weight change on T2D therapy and consider its impact on adherence and discontinuation. METHODS Searches were conducted in MEDLINE and EMBASE (2005 to September 2020), and among recent congress abstract books for studies providing data on medication adherence or discontinuation and weight change in people with T2D (PwD). RESULTS Nine studies meeting the inclusion criteria were identified from 9188 bibliographic records. All three studies exploring weight change and discontinuation reported weight loss to be associated with higher persistence. Seven studies of varying design explored weight change and adherence. Four reported absolute weight change (kg) and adherence: one pooled data from different diabetes medications and demonstrated that self-reported adherence was significantly associated with weight loss; however, three studies found that weight change in adherent PwD was in the direction of the known weight profile (loss/gain) of the evaluated drug. Categorical weight loss (≥3%) and adherence were reported in two studies: one reported that numerically more adherent versus non-adherent PwD lost ≥3% weight regardless of the drug's weight profile, the other showed that early weight loss with a glucagon-like peptide-1 agonist was significantly associated with better adherence. One study reported adherence by categorical weight change; as weight loss increased, adherence scores improved, regardless of drug type. CONCLUSION Findings suggest that discontinuation rates may be lower in PwD who lose as compared to those who gain weight on T2D treatment. The evidence base on adherence and weight change is more challenging to interpret due to the range of study designs. Given the importance of weight control in T2D, further research exploring the individual's treatment, weight journey, and behaviors over time should be undertaken.

Abstract
INTRODUCTION Reducing dosing frequency may lower treatment burden and improve persistence and adherence. This retrospective, observational study assessed persistence and adherence in patients with type 2 diabetes (T2D) initiating once-weekly or daily injectable glucagon-like peptide-1 receptor agonists (GLP-1 RAs) in US clinical practice. METHODS The study used data from adults (≥ 18 years) with T2D who were included in the IBM MarketScan Explorys Claims-EMR Data Set for ≥ 180 days pre-index and ≥ 365 days post-index, were GLP-1 RA and insulin naïve at first claim (index date) for once-weekly or daily injectable GLP-1 RAs (follow-up: index date + 365 days), and were propensity score (PS) matched 1:1 by baseline characteristics. Persistence, defined as the stay time, was assessed using Kaplan-Meier analysis and Cox proportional hazards models. Adherence was defined as a proportion of days covered of 0.8 or greater. To assess whether patients with more advanced disease would benefit from long-acting treatments, patients were matched to the baseline characteristics of basal insulin initiators using inverse probability of treatment weighting (IPTW). RESULTS The PS-matched cohorts (n = 784 each) had similar baseline characteristics. Once-weekly regimens were associated with significantly higher persistence than daily treatments (median stay time: 333 vs 269 days; hazard ratio 0.80 [95% confidence interval 0.71, 0.90]; p < 0.01) and with significantly higher adherence than daily regimens at 6 months and 12 months (p < 0.01 for both). Mean glycated haemoglobin reductions were greater with once-weekly than with daily treatment at 6 months (- 1.1% vs - 0.9%; p < 0.01) and 12 months (- 0.9% vs - 0.7%; p = not significant); adherent patients experienced greater reductions than those with poor adherence. Results were similar in the IPTW-matched analysis. CONCLUSION In US clinical practice, once-weekly injectable treatments are associated with better persistence and adherence than daily regimens over 1 year. Once-weekly regimens may also benefit patients with more advanced T2D.

Abstract
Basal insulin treatment is indispensable for patients with type 1 diabetes and often required by many with type 2 diabetes. Incremental advances lengthening the duration of action of insulin analogs and reducing pharmacodynamic variability have resulted in truly once-daily, long-acting basal insulin analogs. In the quest for better basal insulins to facilitate improvements in glycemic control and long-term outcomes, the driving need is to remove barriers delaying timely initiation of basal insulin, to maximize treatment adherence and persistence and reduce treatment burden without increasing risk of hypoglycemia. We review the range of investigational once-weekly insulins and their molecular strategies and profiles. Currently, the two most advanced clinical development programs are: (1) basal insulin icodec, an insulin analog acylated with a C20 fatty diacid (icosanedioic acid) side chain (Novo Nordisk) and (2) basal insulin Fc, a fusion protein that combines a single-chain insulin variant with a human immunoglobulin G fragment crystallizable domain (Eli Lilly). Available phase 2 data for these two once-weekly agents show comparable glycemic control to existing once-daily insulin analogs, with no greater risk of hypoglycemia. While phase 3 data are awaited to confirm efficacy and safety, we provide future clinical perspectives on practical considerations for the potential use of once-weekly insulins.

Abstract
The scientific landscape of treatments for type 2 diabetes (T2D) has changed rapidly in the last decade with newer treatments becoming available. However, a large proportion of people with T2D are not able to achieve glycaemic goals because of clinical inertia. The majority of T2D management is in primary care, where clinicians (medical, nursing and pharmacist staff) play an important role in addressing patient needs and achieving treatment goals. However, management of T2D is challenging because of the heterogeneity of T2D and complexity of comorbidity, time constraints, guidance overload and the evolving treatments. Additionally, the current coronavirus disease pandemic poses additional challenges to the management of chronic diseases such as T2D, including routine access to patients for monitoring and communication. Glucagon-like peptide 1 receptor agonists (GLP-1 RAs) are a class of agents that have evolved rapidly in recent years. These agents act in a glucose-dependent manner to promote insulin secretion and inhibit glucagon secretion, as well as enhancing satiety and reducing hunger. As a result, they are effective treatment options for people with T2D, achieving glycated haemoglobin reductions, weight loss and potential cardiovascular benefit, as monotherapy or as add-on to other glucose-lowering therapies. However, given the complexity of managing T2D, it is important to equip primary care clinicians with clear information regarding efficacy, safety and appropriate positioning of GLP-1 RA therapies in clinical practice. This review provides a summary of clinical and real-world evidence along with practical guidance, with the aim of aiding primary care clinicians in the initiation and monitoring of GLP-1 RAs to help ensure that desired outcomes are realised. Furthermore, a benefit/risk tool has been developed on the basis of current available evidence and guidelines to support primary care clinicians in selecting individuals who are most likely to benefit from GLP-1 RA therapies, in addition to indicating clinical situations where caution is needed.
