RESUMO
Diabetes mellitus and obesity are growing health concerns. New pharmacologic interventions have recently begun to play a more notable role in the treatment pathway of these separate but related conditions. In particular, glucagon-like peptide-1 receptor agonists, such as semaglutides (Ozempic, Wegovy) and tirzepatide (Mounjaro), and sodium glucose co-transporter 2 inhibitors, such as dapagliflozin (Farxiga) and empagliflozin (Jardiance), have emerged as treatment options. Multiple clinical trials have demonstrated their efficacy in regulating metabolism, improving glycemic control, and managing long-term weight reduction. However, glucagon-like peptide-1 receptor agonists have also been associated with gastrointestinal side effects, including delayed gastric emptying as well as regurgitation and aspiration during general anesthesia or deep sedation, and sodium glucose co-transporter 2 inhibitors have been associated with severe diabetic ketoacidosis. Therefore, discontinuation of these medications before surgery is imperative. Given the popularity of these medications among the general public, it is essential for hand surgeons, to understand how to appropriately manage them perioperatively. The objective of this article was to review these new diabetes mellitus and weight loss medications, including their mechanisms of action, indications for use, and perioperative management guidelines. Additionally, we will take this opportunity to review perioperative guidelines for other common medications relevant to patients undergoing procedures involving the hand and upper extremity such as antithrombotic medications and rheumatoid arthritis-related immunosuppressive medications. Finally, we will describe how the electronic medical record system can be used to optimize perioperative medication management in this population.
RESUMO
Glucagon-like peptide-1 (GLP-1) agonists play a crucial role in treating type 2 diabetes mellitus and obesity by providing glycemic control and aiding weight management. Despite their widespread use, concerns about serious adverse events have prompted extensive research. This review aims to describe the current understanding of serious adverse events associated with GLP-1 agonists. A comprehensive search of PubMed, Google Scholar and Embase databases was performed starting from 2010. Studies reporting evidence of an association between GLP-1 agonists and serious adverse events from 22 articles (5 case reports, 5 randomized controlled trials (RCTs), 9 real-world data cohort analyses, 2 meta-analyses and 1 systematic review and meta-analysis) were included and categorized by the type of adverse event. While some studies reported risks, including anaphylaxis, cardiovascular, gastrointestinal, psychiatric and thyroid-related events, others found no significant associations. The evidence remains mixed, necessitating further research to fully understand the safety profile of GLP-1 agonists and inform clinical practice.
RESUMO
PURPOSE: Patients with hypothalamic pathology often develop hypothalamic obesity, causing severe metabolic alterations resulting in increased morbidity and mortality. Treatments for hypothalamic obesity have not proven very effective, although the glucagon-like peptide-1 receptor agonist semaglutide has been shown to have positive effects. We examined semaglutide's effect on weight loss in a sample of patients with hypothalamic obesity. METHODS: Four female patients with hypothalamic obesity resulting from treatment of craniopharyngiomas were treated with semaglutide for six months. Whole Body Dual-energy x-ray absorptiometry scans were performed, and blood samples drawn at baseline and after six months. Semaglutide dosages were increased monthly along with tracking of body weight and eating behavior (Three Factor Eating Questionnaire, TFEQ-R18). RESULTS: BMI was reduced in all cases, with an average of 7.9 BMI (range: 6.7 to 10.1) corresponding to a weight loss of 17.0% (range: 11.3-22.4%) or 20.2 kg (range 16.2 kg to 23.4 kg). We found a comparable reduction in total fat mass (17.2%, p = 0.006) and lean mass (16.0%, p = 0.05), whereas bone mass was unchanged (2.6%, p = 0.12). All cases reported an increase in energy levels, improved mobility and physical activity. Unfavorable eating behaviors were reduced after 1 month of treatment (emotional eating - 41 points, p = 0.02, uncontrolled eating - 23 points, p = 0.11). HbA1c and total cholesterol were significantly reduced (p = 0.014 for both). CONCLUSION: Semaglutide is a promising and safe treatment option for HO, that improves eating behavior, reduces weight, and improves metabolic markers.
RESUMO
Diabetic kidney disease (DKD) is a prevalent microvascular complication of diabetes, posing a significant health burden. Semaglutide, a glucagon-like peptide-1 receptor agonist, has shown promise in mitigating renal outcomes in DKD. This systematic review aimed to evaluate the renal effects of semaglutide in individuals with DKD. A comprehensive literature search identified six eligible studies, including two case reports and four cohorts, from diverse geographic locations. The primary outcomes assessed were changes in estimated glomerular filtration rate (eGFR) and albuminuria. Secondary outcomes included acute kidney injury (AKI) incidence and other renal biomarkers. The impact of semaglutide on eGFR was variable, with some studies reporting decreases and others showing improvements or no significant changes. Albuminuria, however, was more consistently reduced, particularly in patients with macroalbuminuria. Notably, the case reports described semaglutide-associated AKI, including acute interstitial nephritis, highlighting the need for careful monitoring during therapy. Beyond renal outcomes, semaglutide consistently improved glycemic control and promoted weight loss, with generally manageable gastrointestinal side effects. The findings suggest that semaglutide may effectively reduce albuminuria in DKD, potentially slowing disease progression. However, the risk of AKI and the variable impact on eGFR underscore the need for a personalized approach and vigilant monitoring, particularly in patients with advanced CKD. Future large-scale, long-term randomized controlled trials are warranted to definitively assess the renal benefits and risks of semaglutide in DKD.
RESUMO
The use of glucagon-like peptide-1 receptor agonists (GLP-1RA) has experienced rapid growth amidst the obesity epidemic in the United States. While originally developed for glucose control in Type 2 Diabetes Mellitus, the scope of these agents now extends to encompass weight loss and cardiovascular risk reduction. GLP-1RAs have the potential to induce significant weight loss, in combination with lifestyle modifications, among adults who are overweight or obese. Furthermore, these agents demonstrate efficacy in ameliorating hyperglycemia, enhancing insulin sensitivity, regulating blood pressure, improving cardiometabolic parameters, mitigating kidney dysfunction, and potentially reducing the risk of several obesity-related cancers. Drug-related toxicity is primarily gastrointestinal and active management can prevent drug discontinuation. Obesity is associated both with an increased incidence of malignancy but also with decreased survival. More research is needed to evaluate the potential use of GLP-1RA to modify the endocrine function of adipocytes, regulate the chronic inflammatory state associated with obesity, and prospective applications in oncology. These agents can impact patients with gynecologic malignancies both through their direct mechanism of action as well as potential drug toxicity.
RESUMO
PURPOSE: Patients with tumors involving the hypothalamic region are at high risk of developing morbid obesity due to disturbances in the appetite regulative nuclei in hypothalamus. We evaluated the effect of the Glucagon-like peptide 1 (GLP-1) analogue semaglutide in patients with hypothalamic obesity. METHODS: We recorded weight changes from real-time data before and after treatment with semaglutide in patients with hypothalamic obesity from our outpatient clinic at the Department of Endocrinology at Rigshospitalet, from September 2020 to November 2023. RESULTS: A total of 26 patients were included in this study (15 females, median age at initiation of semaglutide was 52 (range 18-65) years). Body mass index (BMI) at initial diagnosis was median 25 (range 20-38) kg/m2 while BMI at initiation of semaglutide was median 38 (range 28-58) kg/m2. All but one patient lost weight during semaglutide treatment with a mean weight loss of 13.4 kg (95% CI 10.3-16.5 kg, p = < 0.001) after 12 months corresponding to a loss in BMI of 4.4 kg/m2 (95% CI 3.4-5.4 kg/m2, p = < 0.001) with a median dosage of semaglutide of 1.6 (range 0.5-2.5) mg. Fifteen patients (58%) lost more than 10% and two patients (8%) lost more than 20% of initial body weight, respectively. CONCLUSION: Treatment with semaglutide shows promising results in reducing body weight in patients with acquired hypothalamic obesity. Whether the weight reduction remains stable after long time follow-up needs further investigation.
RESUMO
Background: Glucagon-like peptide-1 (GLP-1) has crucial impact on glycemic control and weight loss physiologically. GLP-1 receptor agonists have been approved for treatment of diabetes and obesity. Emerging evidence suggests that GLP-1 receptor agonists exert anticancer effect in tumorigenesis and development. However, the role and mechanism of GLP-1 signaling-related genes in pan-cancer still need further study. Methods: We comprehensively investigated the aberrant expression and genetic alterations of GLP-1 signaling-related genes in 33 cancer types. Next, GLP-1 signaling score of each patient in The Cancer Genome Atlas were established by the single-sample gene set enrichment analysis. In addition, we explored the association of GLP-1 signaling score with prognostic significance and immune characteristics. Furthermore, qRT-PCR and immunohistochemistry staining were applied to verify the expression profiling of GLP-1 signaling-related genes in colorectal cancer (CRC) tissues. Wound-healing assays and migration assays were carried out to validate the role of GLP-1 receptor agonist in CRC cell lines. Results: The expression profiling of GLP-1 signaling-related genes is commonly altered in pan-cancer. The score was decreased in cancer tissues compared with normal tissues and the lower expression score was associated with worse survival in most of cancer types. Notably, GLP-1 signaling score was strongly correlated with immune cell infiltration, including T cells, neutrophils, dendritic cells and macrophages. In addition, GLP-1 signaling score exhibited close association with tumor mutation burden, microsatellite instability and immunotherapy response in patients with cancer. Moreover, we found that the expression of GLP-1 signaling-related genes ITPR1 and ADCY5 were significantly reduced in CRC tissues, and GLP-1 receptor agonist semaglutide impaired the migration capacity of CRC cells, indicating its protective role. Conclusion: This study provided a preliminary understanding of the GLP-1 signaling-related genes in pan-cancer, showing the prognosis significance and potential immunotherapeutic values in most cancer types, and verified the potential anticancer effect of GLP-1 receptor agonist in CRC.
RESUMO
Glucagon-like peptide 1 receptor agonists (GLP-1RA) are guideline recommended agents for the treatment of type 2 diabetes mellitus (T2DM) and select agents (liraglutide and semaglutide) are FDA approved as anti-obesity pharmacotherapy options. These drugs act on the incretin hormone system within the body to revive insulin excretion, delay gastric emptying, and inhibit the production of glucagon from pancreatic alpha cells. Acute pancreatitis is a serious condition that may have a fatal outcome. It has been shown, and is now part of the prescribing information label, that GLP-1RA agents can cause changes in the pancreas that may ultimately lead to pancreatitis. We describe the case of a 53-year-old female patient with uncontrolled type II diabetes mellitus, who experienced multiple episodes of pancreatitis, from what we suspect was due to repeated exposure to the GLP-1 RA agent, semaglutide. After discontinuation of semaglutide, our patient experienced another episode of pancreatitis roughly 15-week later; which we believe may be due to the patient experiencing the effects of a smoldering pancreas brought on by repeated injury and prolonged circulation of semaglutide post-discontinuation.
RESUMO
PURPOSE OF REVIEW: The approval of resmetirom brings great hope to patients with metabolic dysfunction-associated steatohepatitis (MASH). The purpose of this review is to explore its impact on the global health environment. The implementation of multidisciplinary management MASH is proposed. RECENT FINDINGS: Resmetirom has benefits in the treatment of MASH, and its safety and effectiveness have been studied. The adverse events (AEs) need to be noticed. To improve patient outcomes, a multimodal approach with medication such as resmetirom, combined with metabolic and bariatric surgery (MBS) and lifestyle interventions can be conducted. MASH, a liver disease linked with obesity, is a challenging global healthcare burden compounded by the absence of any approved pharmacotherapy. The recent conditional approval by the Food and Drug Administration (FDA) in the United States of resmetirom, an oral, liver-directed, thyroid hormone receptor beta-selective agonist, marks a significant milestone, offering a treatment option for adults with non-cirrhotic MASH and who have moderate to advanced liver fibrosis. This narrative review discusses the efficacy and safety of resmetirom and its role in the therapeutic landscape of MASH treatment. Despite the promising hepatoprotective effect of resmetirom on histological liver endpoints, its use need further research, particularly regarding ethnic differences, effectiveness and cost-effectiveness, production scalability, social acceptance and accessibility. In addition, integrating resmetirom with other multidisciplinary therapeutic approaches, including lifestyle changes and MBS, might further improve clinical liver-related and cardiometabolic outcomes of individuals with MASH. This review highlights the importance of a comprehensive treatment strategy, supporting continued innovation and collaborative research to refine treatment guidelines and consensus for managing MASH, thereby improving clinical patient outcomes in the growing global epidemic of MASH. Studies done to date have been relatively short and ongoing, the course of the disease is highly variable, the conditions of various patients vary, and given this complex clinical phenotype, it may take many years of clinical trials to show long-term benefits.
RESUMO
Background: Cardiovascular outcome trials indicate renal benefits of glucagon-like peptide-1 receptor agonists (GLP-1RAs); however, real-world efficacy and safety studies in Diabetic kidney disease (DKD) are scarce. Methods: This retrospective, single-arm real-world trial involved adults with DKD treated with GLP-1RA for at least 6 months. The primary endpoint was hemoglobin A1c (HbA1c) levels after 6 months. Results: This study included a total of 364 patients with DKD, 153 (42.0%) of whom were female. The median disease duration was 8.0 years, and the mean values of age, HbA1c level, body mass index, and the urinary albumin-to-creatinine ratio (UACR) were 52.1 years, 8.6%, 27.8 kg/m2, and 88.0 mg/g, respectively. Additionally, 73.6% and 26.4% of patients had mild and moderate DKD, respectively. Following 6 months of GLP-1RA treatment, the mean HbA1c level and UACR declined by 1.77% and 40.3%, respectively (both p < 0.001). Compared to their baseline values, patients exhibited significant improvements in 24-h urinary protein, estimated glomerular filtration rate (eGFR), fasting blood glucose, body weight, systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol, triglycerides, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol (all p < 0.001). Patients with a disease duration of <10 years had more pronounced changes in the HbA1c level, UACR, and eGFR (all p < 0.001) than those with a disease duration of ≥10 years. Changes in SBP and DBP were more pronounced in patients also taking angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers (ACEis/ARBs) than in those not taking ACEis/ARBs, whereas the changes in UACR and eGFR did not significantly differ. Conclusion: Six-month GLP-1RA treatment improves glucose, blood pressure, lipids, and body weight in patients with mild-to-moderate DKD while slowing down kidney disease progression. It independently reduces proteinuria beyond ACEi/ARB impact, with early use yielding faster outcomes, supporting evidence-based practice.
RESUMO
Objective: Treatment of obesity has been transformed by the recent approval of incretin-based therapies for weight loss (e.g., glucagon-like peptide 1 agonist semaglutide), but little is known about patient perspectives on these medications. Methods: Between December 2023 and March 2024, healthcare patients from an academic medical center in the Southeast United States with Body Mass Index ≥30 kg/m2 completed a cross-sectional online survey on attitudes toward incretin-based medications. Results: Compared to patients with a bachelor's degree, those without a degree were less likely to be aware of incretin-based pharmacotherapies (96% vs. 78%) and to have discussed pharmacotherapies with a doctor (43% vs. 27%) but had greater interest in using these pharmacotherapies (4.3 vs. 4.7). These pharmacotherapy-related variables did not differ significantly according to gender, race, or financial security. Concerns about side effects, long-term health risks, and potential for weight regain were highly endorsed and were associated with lower interest in using incretin-based therapies and with some demographic factors. Patients reported high interest in lifestyle programs designed for individuals taking anti-obesity medications. Conclusion: Demographic considerations, notably education level, should be factored into the strategy to promote equitable utilization of incretin-based therapies, particularly as their accessibility expands.
RESUMO
AIM: To compare the effectiveness of adding a glucagon-like peptide-1 receptor agonist (GLP-1 RA) with adding basal insulin among adults with type 2 diabetes (T2D) and chronic kidney disease (CKD) already treated with a sodium-glucose co-transporter-2 inhibitor (SGLT2i) and not reaching their glycaemic control targets. METHODS: A retrospective analysis of the Canadian LMC Diabetes Registry was conducted. Adults who initiated a GLP-1 RA were matched 1:1 to adults who initiated basal insulin in a T2D and CKD population. Changes in metabolic outcomes were evaluated at 26-52 weeks following the therapy start date. RESULTS: Propensity score matching was used to match participants who initiated a GLP-1 RA to participants who initiated basal insulin (n = 153/cohort). A significantly greater reduction in HbA1c at 26-52 weeks of follow-up was observed in the GLP-1 RA cohort compared with the basal insulin cohort (-1.3% ± 1.4% vs. -1.1% ± 1.4%, P = .03). Weight was significantly reduced (-3.4 ± 3.7 vs. 2.6 ± 4.5 kg, P < .001), and the estimated glomerular filtration rate decline slowed significantly (-0.3 ± 8.2 vs. -2.4 ± 10.4 mL/min/1.73m2, P = .02), but the change in albuminuria was not significantly different (-5.7 ± 38.1 vs. -0.5 ± 38.3 mg/mmol, P = .47) at follow-up in the GLP-1 RA group compared with the basal insulin group. No differences in self-reported hypoglycaemic events per week and therapy discontinuations were reported between the cohorts. CONCLUSIONS: The study shows the real-world effectiveness of GLP-1 RA therapy for T2D and CKD. GLP-1 RAs provided superior reductions in HbA1c and weight, and greater kidney protection, compared with basal insulin among adults with T2D and CKD already treated with an SGLT2i.
RESUMO
BACKGROUND AND AIMS: Video capsule endoscopy (VCE) is valuable for assessing conditions like gastrointestinal bleeding, anemia, and inflammatory bowel disease. Glucagon-like peptide-1 receptor agonists (GLP-1 RA) are prescribed for diabetes and weight loss, with their pharmacologic effects including delaying gastric emptying. This study investigates the impact of GLP-1 RA usage on VCE outcomes in patients with diabetes. METHODS: This retrospective cohort study involves patients with diabetes undergoing VCE while on GLP-1 RA, matched 1:1 ratio with controls based on demographics and diabetes related factors, who are not on GLP-RA. The primary outcome is gastric transit time in VCE studies, with secondary outcome being incomplete small bowel evaluation and the small bowel transit time. RESULTS: In the 68 GLP-1 RA patient cohort, five (7%) experienced VCE failure to pass through the stomach, while all controls passed successfully (p=0.06). GLP-1 RA patients had longer gastric transit time (99.3 ± 134.2 minutes) compared to controls (25.3 ± 31.6 minutes, p <0.001). Multivariate analysis revealed GLP-1 RA usage was associated with increased gastric transit time by 74.5 minutes (CI: 33.8-115.2, p <0.001) compared to controls, after adjusting on relevant factors. Sixteen GLP-1 RA patients (23.5%) experienced incomplete passage of the VCE through the small intestine, a significantly higher rate compared to three patients in the control group (4.4%) (p<0.01). CONCLUSIONS: GLP-1 RA usage is associated with prolonged gastric transit time and a higher rate of incomplete small bowel evaluation during VCE. Future studies may be crucial for evaluating strategies to mitigate these effects.
RESUMO
INTRODUCTION: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs), approved by the US FDA for obesity treatment, are typically administered subcutaneously, an invasive method leading to suboptimal patient adherence and peripheral side effects. Additionally, this route requires the drug to cross the restrictive blood-brain barrier (BBB), limiting its safety and effectiveness in weight management and cognitive addiction disorders. Delivering the drug intranasally could overcome these drawbacks. AREAS COVERED: This review summarizes GLP-1 RAs used as anti-obesity agents, focusing on the intranasal route as a potential pathway to deliver these biomolecules to the brain. It also discusses strategies to overcome challenges associated with nasal delivery. EXPERT OPINION: Nose-to-brain (N2B) pathways can address limitations of the subcutaneous route for GLP-1 RAs. However, peptide delivery to the brain is challenging due to nasal physiological barriers and the drug's physicochemical properties. Innovative approaches, such as cell permeation enhancers, mucoadhesive systems, and nanocarriers in nasal formulations, along with efficient drug delivery devices, show promising preclinical results. Despite this, successful preclinical data does not guarantee clinical effectiveness, highlighting the need for comprehensive clinical investigations to optimize formulations and fully utilize the nose-to-brain interface for peptide delivery.
RESUMO
The regulation of plasma amino acid levels by glucagon in humans first attracted the attention of researchers in the 1980s. Recent basic research using animal models of glucagon deficiency suggested that a major physiological role of glucagon is the regulation of amino acid metabolism rather than to increase blood glucose levels. In this regard, novel feedback regulatory mechanisms that are mediated by glucagon and amino acids have recently been described between islet alpha cells and the liver. Increasingly, hyperglucagonemia in humans with diabetes and/or nonalcoholic fatty liver diseases is reported to likely be a compensatory response to hepatic glucagon resistance. Severe glucagon resistance due to a glucagon receptor mutation in humans causes hyperaminoacidemia and islet alpha cell expansion combined with pancreatic hypertrophy. Notably, a recent report showed that the restoration of glucagon resistance by liver transplantation resolved not only hyperglucagonemia, but also pancreatic hypertrophy and other metabolic disorders. The mechanisms that regulate islet cell proliferation by amino acids largely remain unelucidated. Clarification of such mechanisms will increase our understanding of the pathophysiology of diseases related to glucagon.
RESUMO
Glucagon has many functions: it promotes glucose production, fatty acid oxidation, thermogenesis, energy consumption, lipolysis, and myocardial contraction, and suppresses lipogenesis, appetite, and gastrointestinal motility. Which of these functions are physiological and which are pharmacological is not fully understood. Although the Mercodia sandwich ELISA provides significantly higher specificity of glucagon measurement than does conventional competitive RIA, it cannot provide accurate plasma glucagon values in the presence of elevated cross-reacting plasma glicentin. This occurs in patients post-pancreatectomy or bariatric surgery and in around 30% of outpatients suspected for glucose intolerance who have not had surgery. Thus, our newly developed sandwich ELISA with higher specificity and higher sensitivity than the Mercodia sandwich ELISA is needed for accurate measurements of plasma glucagon in diabetic patients. It is expected that the new sandwich ELISA will contribute to personalized medicine for diabetes by its use in clinical tests to accurately diagnose the conditions of diabetic patients in order to design better individual treatment strategies. Meanwhile, clinical trials are being conducted worldwide to apply glucagon/GLP-1 receptor dual agonists and glucagon/GLP-1/GIP receptor triagonists to the treatment of obesity, fatty liver, and diabetes. Most clinical trials have shown that both types of drugs have stronger effects on weight reduction, improving fatty liver, and glucose tolerance than do the single GLP-1 receptor agonists. Glucagon is expected to be used as a new diagnostic marker and in a new therapeutic strategy based on a true understanding of its physiological and pharmacological functions.
RESUMO
The cold climates in autumn and winter threatens human health. The aim of this study was to reveal the effects of prolonged cold exposure on the liver and pancreas based on GLP-1R signaling, oxidative stress, endoplasmic reticulum (ER) stress and ferroptosis by Yorkshire pig models. Yorkshire pigs were divided into the control group and chronic cold stress (CCS) group. The results showed that CCS induced oxidative stress injury, activated Nrf2 pathway and inhibited the expression of GLP-1R in the liver and pancreas (P < 0.05). The toll-like receptor 4 (TLR4) pathway was activated in the liver and pancreas, accompanied by the enrichment of IL-1ß and TNF-α during CCS (P < 0.05). Moreover, the kinase RNA-like endoplasmic reticulum kinase (PERK), inositol requiring kinase 1 (IRE1), X-box-binding protein 1 (XBP1) and eukaryotic initiation factor 2α (eIF2α) expression in the liver and pancreas was up-regulated during CCS (P < 0.05). In addition, CCS promoted the prostaglandin-endoperoxide synthase 2 (PTGS2) expression and inhibited the ferritin H (FtH) expression in the liver. Summarily, CCS promotes inflammation, ER stress and apoptosis by inhibiting the GLP-1R signaling and inducing oxidative stress, and exacerbates the risk of ferroptosis in the liver and pancreas.
RESUMO
BACKGROUND AND AIMS: The Semaglutide Effects on Cardiovascular Outcomes in People with Overweight or Obesity (SELECT) trial demonstrated significant reductions in cardiovascular outcomes in people with cardiovascular disease (CVD) and overweight or obesity (but without diabetes). However, the cost of the medication has raised concerns about its financial viability and accessibility within healthcare systems. This study explored whether use of semaglutide for the secondary prevention of CVD in overweight or obesity is cost-effective from the Australian healthcare perspective. METHODS: A Markov model was developed based on the SELECT trial to model the clinical outcomes and costs of a hypothetical population treated with semaglutide versus placebo, in addition to standard care, and followed up over 20 years. With each annual cycle, subjects were at risk of having non-fatal CVD events or dying. Model inputs were derived from SELECT and published literature. Costs were obtained from Australian sources. All outcomes were discounted by 5% annually. The main outcome of interest was the incremental cost-effectiveness ratio (ICER) in terms of cost per year of life saved (YoLS) and cost per quality-adjusted life year (QALY) gained. RESULTS: With an annual estimated cost of semaglutide of A${\$}$4175, the model resulted in ICERs of A${\$}$99 853 (US${\$}$143 504; £40 873) per YoLS and A${\$}$96 055 (US${\$}$138 046; £39 318) per QALY gained. CONCLUSIONS: Assuming a willingness-to-pay threshold of A${\$}$50 000, semaglutide is not considered cost-effective at the current price. A price of ≤ A${\$}$2000 per year or more targeted use in high-risk patients would be needed for it to be considered cost-effective in the Australian setting.
