Abstract
AIMS/HYPOTHESIS Our aim was to assess treatment discontinuation, reinitiation and switching between drugs within the same drug class for glucagon-like peptide-1 (GLP-1) receptor agonists and sodium-glucose cotransporter 2 (SGLT2) inhibitors in individuals with type 2 diabetes. METHODS We used data from nationwide registers in Sweden to perform separate analyses for all patients with type 2 diabetes who filled a first prescription of a GLP-1 receptor agonist or an SGLT2 inhibitor between 2017 and 2021. Patients were considered to be on treatment for the period during which prescriptions were refilled before the estimated end date of the most recent prescription, including a 90-day grace period, i.e. the time allowed between and after prescriptions before treatment is considered as discontinued. We used the Aalen-Johansen estimator to estimate cumulative incidences of discontinuation and reinitiation, and Fine-Gray sub-distribution hazard models to assess the association of clinical variables with the risk of discontinuation. RESULTS Among 73,895 new users of GLP-1 receptor agonists, the cumulative incidence of treatment discontinuation was 23.6% at 1 year and 38.5% at 3 years. Among patients who discontinued, the cumulative incidence of treatment reinitiation was 41.1% at 1 year and 57.4% at 3 years after discontinuation. Among 113,207 new users of SGLT2 inhibitors, the cumulative incidence of treatment discontinuation was 27.9% at 1 year and 45.9% at 3 years, with a cumulative incidence of reinitiation of 40.4% at 1 year and 55.7% at 3 years after discontinuation. When varying the grace period between 60 days and 365 days, treatment discontinuation rates at 3 years ranged from 23.3% to 43.6% among GLP-1 receptor agonist users and from 28.8% to 50.6% among SGLT2 inhibitor users. The proportion of patients who had ongoing treatment, regardless of previous discontinuation episodes, ranged between approximately 70% and 80% for both drugs during a 1-5 year period after treatment initiation across analyses using various grace periods. In terms of switching, 22.9% of the GLP-1 receptor agonist users and 2.1% of the SGLT2 inhibitor users switched between drugs within the same drug class. Patient characteristics associated with treatment discontinuation were similar for GLP-1 receptor agonists and SGLT2 inhibitors, although the association between higher BMI and a lower likelihood of treatment discontinuation was stronger for GLP-1 receptor agonists. CONCLUSIONS/INTERPRETATION Approximately half of type 2 diabetes patients who had started using GLP-1 receptor agonists or SGLT2 inhibitors had discontinued treatment within 5 years of follow-up. However, more than half of those who discontinued treatment subsequently reinitiated treatment, such that the proportion with ongoing treatment was approximately 70-80% for both drugs during a 1-5 year period after treatment initiation. This suggests that the proportion of patients with long-term use of the medications is larger than indicated by analyses focusing on treatment discontinuation. Patient characteristics associated with treatment discontinuation were similar for GLP-1 receptor agonists and SGLT2 inhibitors.

Abstract
The objective of this study is to quantitatively compare the weight loss effects of glucagon-like peptide-1 receptor agonists (GLP-1RAs) in adult patients with no diabetes and type 2 diabetes (T2D). PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), and Embase have been used as data sources from database inception to January 6, 2024. A total of 137 trials, encompassing 310 treatment arms, 17 GLP-1RAs, and 56,683 patients, were included in the analysis. The included trials were divided into three groups based on the characteristics of the populations: nondiabetic overweight or obesity group (NDOOG), type 2 diabetes Caucasian group (T2DCG), and type 2 diabetes Asian group (T2DAG). The effects of covariates were further evaluated, patients with a higher baseline body weight tend to have better weight loss outcomes, and patients with a higher baseline glycated hemoglobin (HbA1c) tend to achieve better blood sugar control. Five mathematical models were subjected to longitudinal analysis. In terms of Δ body weight, retatrutide (12 mg qw) was the most effective treatment (mean difference = -26.56% [95% confidence interval: -43.89% to -3.01%]). Tirzepatide (15 mg qw) demonstrated good weight loss ability in all three ΔBW models, ΔBW-NDOOG (-22.76% [-26.45% to -18.50%]), ΔBW-T2DCG (-11.09% [-12.39% to -9.44%])), and ΔBW-T2DAG (-4.97% [-5.84% to -4.12%]). In the aspect of ΔHbA1c, tirzepatide (10 mg qw) and oral orforglipron (10 mg qd) were the most effective drug, respectively. GLP-1RAs demonstrated effective weight management in both nondiabetic and T2D populations. Retatrutide achieved the most pronounced weight reduction, followed by tirzepatide. GLP-1RAs also significantly improved glycemic control for patients with T2D, with tirzepatide performing the best for glycemic control.

Clinical characteristics, treatment patterns, and persistence in individuals with type 2 diabetes initiating a glucagon-like peptide-1 receptor agonist: A retrospective analysis of the Diabetes Prospective Follow-Up Registry. Diabetes Obes Metab 2023. [PMID: 36855221 DOI: 10.1111/dom.15038] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 02/22/2023] [Accepted: 02/24/2023] [Indexed: 03/02/2023]
Abstract
AIMS To describe clinical characteristics, treatment patterns and glucagon-like peptide-1 receptor agonist (GLP-1 RA) persistence in individuals with type 2 diabetes (T2D) initiating their first GLP-1 RA. MATERIALS AND METHODS A real-world analysis of adults with T2D initiating GLP-1 RA therapy between 2007 and June 2020 from the multicentre Diabetes Prospective Follow-Up (DPV) Registry, stratified by antidiabetes therapy at the time of GLP-1 RA initiation: oral antidiabetic drugs (OAD), insulin ± OAD or lifestyle modification (LM). GLP-1 RA treatment persistence in individuals with ≥12 months follow-up was determined by Kaplan-Meier analysis. RESULTS Overall, 15 111 individuals with T2D initiating GLP-1 RA therapy (55% men) were identified; median [interquartile range (IQR)] age [58.7 (50.6-66.7) years], diabetes duration [8.5 (3.6-14.7) years], glycated haemoglobin [HbA1c; 8.2 (7.1-9.8)%]. Median (95% confidence interval) GLP-1 RA persistence in eligible individuals (n = 5189) was 11 (10-12) months; OAD 12 (11-14) months (n = 2453); insulin ± OAD 11 (9-12) months (n = 2204); and LM 7 (5-9) months (n = 532). Median treatment persistence tended to increase from 2007-2012 to 2017-2020. Median (IQR) HbA1c decreased from baseline [8.2 (7.1-9.8)%] to discontinuation [7.5 (6.6-8.7)%], with a greater decrease observed in individuals with persistence >12 months versus ≤12 months. Individuals who discontinued GLP-1 RA therapy predominantly switched to insulin (if not already using) or dipeptidyl peptidase-4 inhibitors. CONCLUSION Real-world registry data revealed improved outcomes with longer median GLP-1 RA persistence; ~50% of patients overall achieved HbA1c <7% at 12 months. Persistence was highest with baseline OAD and/or insulin, and tended to increase over the period 2007-2020.

Abstract
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are indicated in type 2 diabetes and obesity for their high efficacy in controlling glycaemia and inducing body weight loss, respectively. Patients may develop gastrointestinal adverse events (GI AEs), namely nausea, vomiting, diarrhoea and/or constipation. To minimize their severity and duration, healthcare providers (HCPs) and patients must be aware of appropriate measures to follow while undergoing treatment. An expert panel comprising endocrinologists, nephrologists, primary care physicians, cardiologists, internists and diabetes nurse educators convened across virtual meetings to reach a consensus regarding these compelling recommendations. Firstly, specific guidelines are provided about how to reach the maintenance dose and how to proceed if GI AEs develop during dose-escalation. Secondly, specific directions are set about how to avoid/minimize nausea, vomiting, diarrhoea and constipation symptoms. Clinical scenarios representing common situations in daily practice, and infographics useful to guide both HCPs and patients, are included. These recommendations may prevent people with T2D and/or obesity from withdrawing from GLP-1 RAs treatment, thus benefitting from their superior effect on glycaemic control and weight loss.

Abstract
Aim This study's aim was to compare the time and accuracy of use and participants' satisfaction and preferences with pen devices for the once-weekly glucagon-like peptide 1 (GLP-1) receptor agonists dulaglutide, exenatide XR BCise, and semaglutide. Materials and methods In this triple crossover, open-label, simulated injection study, GLP-1 receptor agonist pen devices were compared, with time and accuracy of use and participants' satisfaction and preferences as primary outcomes. Participants had type 2 diabetes and were naive to GLP-1 receptor agonist therapy. Participants watched instructional videos for each device, demonstrated administration, and then provided feedback after each demonstration. Investigators tracked errors and omissions of demonstration steps for accuracy and time. Differences across devices were compared using univariate mixed models, adjusting for multiple comparisons. Results Of the 60 participants, 50% were male, a majority (65%) were Caucasian, and most (65%) had adequate health literacy. Participants rated the dulaglutide device easier to use than those of exenatide XR BCise or semaglutide (P <0.001 for each). Participants expressed greater satisfaction with the dulaglutide device compared with those of exenatide XR BCise or semaglutide (P <0.01 for each). Most participants (75%) preferred the dulaglutide device overall; however, many participants (61%) preferred the size and portability of the semaglutide device. The dulaglutide device took less time to use than the exenatide XR BCise or semaglutide devices (69 vs. 126 and 146 seconds, respectively; P <0.001 for each). Participants were less accurate when using the dulaglutide device. Conclusion Most participants preferred the dulaglutide device. The dulaglutide device took the least amount of time to demonstrate; however, demonstration accuracy was lower.

Abstract
The objective of this paper was to review the adherence and persistence rates of major antidiabetic medication classes (i.e., metformin, sulfonylureas, sodium glucose cotransporter-2 inhibitors, dipeptidyl peptidase-4 inhibitors, insulin, glucagon-like peptide-1 receptor agonists, and thiazolidinediones) by summarizing the major findings of the studies published since 2017. In addition, we reported the potential causes for low adherence and persistence of antidiabetic medications. Based on the literature, the highest rate of adherence and persistence was consistently observed in metformin users. Second to metformin were sodium glucose cotransporter-2 inhibitors. Injectable therapies such as insulin and glucagon-like peptide-1 receptor agonists trailed low on the adherence and persistence rates. To the best of our knowledge, no studies published since the year 2017 analyzed the adherence and persistence of thiazolidinediones independently. The most frequently cited cause for low adherence and persistence was the severity of adverse events. Baseline characteristics (e.g., baseline HbA1c level), demographic information (e.g., age, gender, or ethnicity), and comorbidity profiles also had significant impacts on adherence and persistence in patients with type 2 diabetes mellitus.

Abstract
AIM To compare treatment persistence in patients with type 2 diabetes initiating the glucagon-like peptide-1 receptor agonists (GLP-1 RAs) dulaglutide, exenatide once-weekly (QW), liraglutide or lixisenatide in routine clinical practice in Sweden and assess clinical outcomes. MATERIALS AND METHODS We performed a retrospective study using data from several nationwide Swedish health registries, including the National Diabetes Register and other mandatory and population-based registries. Individual level data were collected from 17 361 patients who initiated GLP-1 RA treatment from 23 May 2015 to 15 October 2017, up to 2.5 years postindex (treatment start date). Treatment persistence and modification, predictors of discontinuation, HbA1c and body weight were recorded. Non-persistence was defined as a treatment gap of more than 45 days. Treatment modification included switching and augmentation. Confounding was addressed through the use of propensity scores. RESULTS Treatment persistence was higher and treatment modifications were lower in patients initiating dulaglutide compared with those on exenatide QW, liraglutide and lixisenatide. Patients who remained on the same treatment for 1-year postindex experienced greater HbA1c reductions and a steadier decrease in body weight. CONCLUSIONS Our study suggests that in clinical practice in Sweden there is a greater persistence of treatment among patients initiating dulaglutide compared with those on exenatide QW, liraglutide and lixisenatide. Persistence with the index GLP-1 RA was closely correlated with positive clinical outcomes and thus should be considered a critical factor of patient-centric treatment in Sweden.
