Article Abstract
Introduction: The glucagon-like peptide-1 receptor agonist (GLP-1 RA) class is evolving and expanding. This retrospective database study evaluated recent real-world treatment and dosing patterns of patients with type 2 diabetes (T2D) initiating GLP-1 RAs in Belgium (BE), France (FR), Germany (DE), Italy (IT), the Netherlands (NL), and Canada (CA).
Methods: Adult T2D patients initiating GLP-1 RA therapy (dulaglutide [DULA], exenatide twice daily [exBID], exenatide once weekly [exQW], liraglutide [LIRA], or lixisenatide [LIXI]) from 2015 to 2016 were identified using the IQVIA (IQVIA, Durham, NC, and Danbury, CT, USA) Real-World Data Adjudicated Pharmacy Claims. The therapy initiation date was termed the 'index date.' Eligible patients had ≥ 180 days pre-index and ≥ 360 days post-index. Persistence (until discontinuation or switch) was evaluated over the variable follow-up using Kaplan-Meier (KM) survival analysis. Average daily dose (ADD) was calculated until discontinuation or switch.
Results: A total of 34,649 DULA, 3616 exBID, 11,138 exQW, 48,317 LIRA, and 2,204 LIXI patients were included in the analysis (34.9-63.2% female; median age range 53-62 years; median follow-up 16-30 months). Proportion persistent at 1-year post-index was 36.8-67.2% for DULA, 5.9-44.4% for exBID, 24.7-44.2% for exQW, 22.2-57.5% for LIRA, and 15.5-40.0% for LIXI. Median time persistent (days) was 245-381 for DULA, 62-243 for exBID, 121-319 for exQW, 103-507 for LIRA, and 99-203 for LIXI. Mean ADD was 13.21-20.43 µg for exBID, 1.44-1.68 mg for LIRA, and 19.88-20.54 µg for LIXI. Mean average weekly dose (AWD) ranged from 2.03 to 2.14 mg for exQW. Mean AWD for DULA was 1.25 mg in Canada and ranged from 1.43 to 1.53 mg in the other countries.
Conclusion: Across six countries, persistence was highest among DULA patients and generally lowest among exBID patients. ADD/AWD for all GLP-1 RAs was in line with the recommended label. Longer-term data would be useful to obtain a better understanding of GLP-1 RA treatment patterns over time.

Background: Treatment guidelines recommend metformin as initial drug in many people with type 2 diabetes (T2D) and low risk of cardiovascular disease, with the possibility to switch to or add other drug classes. A decision aid (DA) could be useful to incorporate a patient's preferences in the decision of which drug class to choose. We developed such a DA and assessed the perspectives of people with T2D towards its comprehensibility and usability.

Introduction: Oral Semaglutide (Sema-o) is the first oral glucagon like peptide-1 receptor analogue (GLP-1RA) commercially available for the treatment of type 2 diabetes (T2D). This study aimed to evaluate the efficacy of Sema-o in patients with T2D when added to the existing therapy.
Methods: This retrospective real-world study enrolled adult patients with diabetes taking Sema-o, with at least one follow-up (from February 2022 till October 2023).
Glucagon like peptide-1 (GLP-1) agonists and cardiometabolic protection: historical development and future challenges.

Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have revolutionized the treatment of cardiometabolic diseases, extending their therapeutic applications far beyond glycemic control in type 2 diabetes (T2D) and obesity. This editorial synthesizes key milestones, from the discovery of GLP-1 to recent clinical trials highlighting the pleiotropic effects of GLP-1RAs in addressing the interconnected spectrum of cardiometabolic conditions, with a focus on cardiovascular, renal, and hepatic benefits. In addition, as GLP-1RAs continue to reshape the management of cardiometabolic disease and global public health, we discuss future challenges to better elucidate their mechanisms of cardiometabolic protection and maximize their therapeutic potential.

This study compared the efficacy and safety of glucogan-like peptide-1 receptor agonists (GLP1RAs) combined with metformin versus metformin alone in women with polycystic ovary syndrome (PCOS). A systematic search of "PubMed", "EMBASE", "Cochrane Library", and "Web of Science", "Google Scholar" was conducted up to September 2024. Studies were included if they were RCTs investigating the combination of GLP1RAs and metformin in women diagnosed with PCOS.
