oxyntomodulin and Weight-Loss

Semaglutide is a glucagon-like peptide-1 receptor agonist that was recently approved by the US Food and Drug Administration for chronic weight management. This paper reviews data on the mechanism of action, weight-loss and cardiometabolic efficacy, and safety of semaglutide 2.4 mg/week for obesity. Semaglutide has demonstrated the largest weight loss of any obesity medication to date with reductions of approximately 15% of initial weight at 68 weeks, accompanied by improvements in cardiovascular risks factors and physical functioning. The approval of this medication provides patients with greater options for weight management.

The history of multiple weight loss medications has been a concerning paradox based on an increased cardiovascular risk despite significant reductions in adipose tissue and weight. A new class of weight loss medications could change this past narrative based on early preliminary results of cardiovascular risk (not events-still need to be determined) and weight reduction in non-diabetics that acutely competes with results achieved with bariatric surgery. The purpose of this review is to provide a comprehensive summary of the advantages and disadvantages of these newer medications, and how they could impact urology.. Weight loss of - 15 to - 20% compared to baseline has become plausible in the short-term and preliminary guidance to reduce acute and chronic adverse events are receiving attention. However, the cost, access, conflicts of interest, supply chain, life-long adherence issues, and the long-term diverse implications on mental and physical health when exposed to this class of medications (GLP-1 agonists) are unknown. The profound caloric reductions should also result in baseline or ongoing nutritional deficiency testing, and general and specific dietary recommendations, which could theoretically mimic some bariatric surgery pre- and post-surgical protocols but has yet to be studied. Regardless, the potential impact of these medicines within a variety of medical specialties needs clinical research. Current and future lifestyle interventions, dietary patterns, and medicines in the weight loss category need to be held to a paradigm whereby cardiovascular health should improve with significant weight loss without a negative impact on mental health. In urology, the ability to impact cancer risk, ED, FSD, incontinence, infertility, nephrolithiasis, and multiple other endpoints are plausible (based on bariatric surgery data) but need preliminary clinical research. Other medicines with a similar or even larger potential impact are in clinical trials, and thus, a concise overview for clinicians and researchers was needed for objective guidance. Currently, comprehensive lifestyle changes utilized with and without these medications continue to garner positive mental, physical, and legacy effects, which suggest that they are as necessary as ever in the treatment of the numerous conditions impacted by unhealthy weight gain.

Obesity is a growing epidemic within the USA. Because weight gain is associated with an increased risk of developing life-threatening comorbidities, such as hypertension or type 2 diabetes, there is great interest in developing non-invasive pharmacotherapeutics to help combat obesity. Glucagon-like peptide-1 (GLP-1) receptor agonists are a class of antidiabetic medications that have shown promise in encouraging glycemic control and promoting weight loss in patients with or without type 2 diabetes. This literature review summarizes and discusses the weight loss results from the SUSTAIN (Semaglutide Unabated Sustainability in Treatment of Type 2 Diabetes), PIONEER (Peptide Innovation for Early Diabetes Treatment), and STEP (Semaglutide Treatment Effect in People with Obesity) clinical trial programs. The SUSTAIN and PIONEER clinical trials studied the use of 1.0 mg, once-weekly, subcutaneous and oral semaglutide (a new GLP-1 homolog), respectively, on participants with type 2 diabetes. The STEP trial examined the effects of 2.4 mg, once-weekly, subcutaneous semaglutide on patients with obesity. Trial data and other pertinent articles were obtained via database search through the US National Library of Medicine Clinical Trials and the National Center for Biotechnology Information. All three clinical trials demonstrated that semaglutide (injected or oral) has superior efficacy compared with placebo and other antidiabetic medications in weight reduction, which led to Food and Drug Administration approval of Wegovy (semaglutide) for weight loss.

The purpose of this review paper is to review the efficacy and safety of subcutaneous semaglutide, marketed as Wegovy, a glucagon-like peptide-1 receptor agonist for obesity management.. A MEDLINE search (1970 to June 2021) was conducted to identify Phase 3 trials of subcutaneous semaglutide for obesity management. Published Phase 3 trials from The Semaglutide Treatment Effect in People with obesity (STEP) program were reviewed and summarized.. Based on four Phase 3 trials, subcutaneous semaglutide as 2.4 mg once weekly was compared in efficacy and safety among 5000 randomized participants who were overweight or had obesity. A change in body weight from baseline to end of study was the primary outcome in the STEP program. Participants who received semaglutide had a dose-dependent reduction in body weight from baseline, compared to placebo. Higher percentages of participants had 5%-10% weight reduction from baseline when receiving subcutaneous semaglutide. The patient population was mainly middle-aged female participants with Class II obesity. Additional studies are needed, especially active-comparator trials, to determine the efficacy and safety of semaglutide in a diverse patient population.. Subcutaneous semaglutide is another available option as adjunct therapy to lifestyle modifications for people who are overweight or have obesity based on body weight and body mass index. It resulted in more weight reduction than placebo with gastrointestinal adverse events being the most common safety concerns. Clinical utilization of subcutaneous semaglutide will be determined, as insurance coverage will be a limitation for this new medication.

Cardiovascular disease is the most common cause of morbidity and mortality worldwide, and the risk is heightened in the presence of obesity. We review semaglutide, a drug recently approved for chronic weight management in adults with obesity or who are overweight.. On 4 June 2021, the US Food and Drug Administration approved semaglutide injection at 2.4 mg once weekly for chronic weight management in adults with obesity or overweight with at least one weight-related condition such as high blood pressure, type 2 diabetes mellitus, or high cholesterol. This subcutaneous injection is the first approved drug for chronic weight management in adults with general obesity or overweight since 2014. The drug is indicated for weight management in patients with a BMI of 27 kg/m2 or greater who have at least one weight-related ailment or in patients with a BMI of 30 kg/m2 or greater.. Semaglutide offers adults with obesity or overweight a new treatment in conjunction with a weight management program consisting of reduced calorie diet and increased physical activity.

The approval of once daily liraglutide, 3.0 mg, and once weekly semaglutide, 2.4 mg, for chronic weight management provides a novel effective strategy against obesity. The reliable models that might predict weight reducing potential at the individual level have not been identified yet. However, the coexistence of diabetes has been consistently related with less effective response than in people without this comorbidity. We aimed to review the efficacy of GLP-1 RAs approved for weight management in individuals with and without diabetes and discuss some potential mechanisms for consistently observed differences in efficacy between these two populations. The mean weight loss difference between GLP-1 RAs and placebo as add-on to lifestyle intervention in patients with diabetes was 4% to 6.2% compared to 6.1 to 17.4% in people without diabetes. Semaglutide compared to liraglutide resulted in greater weight loss. Some hypothetical explanations for the weaker anti-obesity response for both GLP-1 RAs in people with diabetes include the background medications that promote weight gain, the fear of hypoglycaemia inherently related to the treatment of diabetes, a decrease in glycosuria and subsequently less weight loss in diabetics, an altered microbiota in patients with obesity and diabetes and a genetic background that predispose to weight gain in patients with diabetes. Moreover, people with diabetes may have had obesity for longer and may be less adherent to exercise, which seems to potentiate the effects of GLP-1 RA. Emerging multimodal approaches combining peptides targeting receptors at different levels might therefore be of additional benefit particularly in patients with diabetes.

Aim To determine the antiobesity effect and safety of glucagon-like peptide-1 receptor agonist (GLP-1RA) including liraglutide, exenatide and semaglutide treatment in overweight/obese patients without diabetes. The random-effect model was used to pool data extracted from included literatures. The weighted mean difference (WMD), odds ratio and 95% confidence interval (CI) were used to present the meta-analysis results (PROSPERO registration number: CRD 42020173199). The sources of intertrial heterogeneity, bias and the robustness of results were evaluated by subgroup analysis, sensitivity analysis and regression analysis, respectively. A total of 24 RCTs were recruited in the present analysis which included 5867 patients. The results showed that the treatment of overweight/obese patients without diabetes with GLP-1RAs including liraglutide, exenatide and semaglutide significantly achieved greater weight loss than placebo [WMD=-5.39, 95% CI (-6.82, -3.96)] and metformin [WMD=-5.46, 95% CI (-5.87, -5.05)]. The subgroup analysis showed that semaglutide displayed the most obvious antiobesity effect in terms of weight loss, the reduction of body mass index (BMI) and waist circumference (WC). However, GLP-1RAs treatments had more gastrointestinal adverse events (such as nausea and vomiting) than placebo and Met. The subgroup analysis also represented that semaglutide displayed the lowest risk of gastrointestinal adverse events among three kinds of GLP-1RAs. Our meta-analysis demonstrated that GLP-1RA had a superior antiobesity effect than placebo/Met in overweight/obese patients without diabetes in terms of body weight, BMI, and WC, especially for semaglutide, which had more obvious antiobesity effect and lower GI adverse events than liraglutide and exenatide.

Obesity is a complex and chronic disease that raises the risk of various complications. Substantial reduction in body weight improves these risk factors. Lifestyle changes, including physical activity, reduced caloric ingestion, and behavioral therapy, have been the principal pillars in the management of obesity. In recent years, pharmacologic interventions have improved remarkably. The Semaglutide Treatment Effect in People with Obesity (STEP) program is a collection of phase-III trials geared toward exploring the utility of once-weekly 2.4 mg semaglutide administered subcutaneously as a pharmacologic agent for patients with obesity. All the STEP studies included diet and exercise interventions but at different intensities. This review paper aims to explore the impact of the behavioral programs on the effect of semaglutide 2.4 mg on weight loss. The results of the STEP trials supported the efficacy of high-dose, once-weekly 2.4 mg semaglutide on body weight reduction among patients with obesity with/without diabetes mellitus. Semaglutide was associated with more gastrointestinal-related side effects compared to placebo but was generally safe and well tolerated. In all the STEP studies, despite the varying intestines of the behavioral programs, weight loss was very similar. For the first time, there may be a suggestion that these behavioral programs might not increase weight reduction beyond the effect of semaglutide. Nevertheless, the importance of nutritional support during substantial weight loss with pharmacotherapy needs to be re-evaluated.

Research on semaglutide's effect on weight loss has been largely focused on Type 2 Diabetics. No meta-analyses of semaglutide's efficacy in non-diabetic individuals have been conducted to date. Expanding the knowledge of semaglutide's outcome in non-diabetics may provide impactful changes at the clinical level.. This systematic review and meta-analysis quantified the efficacy of subcutaneous semaglutide in treating obesity in non-diabetic adult patients compared to placebo.. Academic Search Premier, Cumulative Index to Nursing and Allied Health Literature (CINAHL) complete, MEDLINE with Full Text, Cochrane Central Register of Controlled Trials, medrxiv.org, and clinicaltrials.gov were systematically investigated using a predetermined search strategy from inception to August 21, 2021. Covidence.org was used to screen, select, and extract data by two independent reviewers. Individual study bias was assessed using the Cochrane Risk of Bias 2 tool. Data were exported to RevMan v5.4, where meta-analysis was conducted using a DerSimonian and Laird random-effects model.. The initial search identified 332 relevant articles and ultimately retained four randomized controlled trials encompassing 2,882 participants with a BMI ≥ 27 kg/m. This systematic review and meta-analysis validates the clinical efficacy of semaglutide for the treatment of obesity in the adult, non-diabetic population.

Obesity is a global health challenge. It is a multifactorial, complex, and progressive disease associated with various health complications and increased mortality. Lifestyle modifications are central to weight management but may be insufficient to maintain clinically meaningful weight loss. Pharmacotherapies are recommended as an adjunct to lifestyle interventions to induce and sustain clinically meaningful weight loss and reduce the risk of comorbidities in appropriate patients. Glucagon-like peptide-1 is an incretin metabolic hormone responsible for a range of physiological effects, including glucose and appetite regulation. Several glucagon-like peptide-1 receptor agonists (GLP-1RAs) have been approved for the treatment of type 2 diabetes since 2005 including exenatide (short- and extended-release), lixisenatide, liraglutide, dulaglutide, albiglutide, and semaglutide. Of these, semaglutide (subcutaneous) and liraglutide are currently US Food and Drug Administration (FDA)-approved for chronic weight management in patients with or without diabetes. The phase 3 Semaglutide Treatment Effect in People with obesity (STEP) program was designed to investigate the effect of semaglutide versus placebo on weight loss, safety, and tolerability in adults with overweight or obesity. Following the submission of the results of the STEP 1-4 trials, the FDA approved once-weekly subcutaneous semaglutide 2.4 mg for chronic weight management in people with overweight or obesity in April 2021. Data from the program demonstrated that semaglutide (2.4 mg once weekly) achieved significant and sustained weight loss, together with improvements in cardiometabolic risk factors compared with placebo, and was generally well tolerated, with a safety profile consistent with other GLP-1RAs. The most common adverse events reported in STEP 1-5 were gastrointestinal events, which were transient, mild-to-moderate in severity, and typically resolved without permanent treatment discontinuation. This article reviews the data from STEP 1-5 and highlights clinically relevant findings for primary care providers.

Glucagon-like peptide-1 receptor (GLP-1R) agonists are approved to treat type 2 diabetes and obesity. They elicit robust improvements in glycemic control and weight loss, combined with cardioprotection in individuals at risk of or with pre-existing cardiovascular disease. These attributes make GLP-1 a preferred partner for next-generation therapies exhibiting improved efficacy yet retaining safety to treat diabetes, obesity, non-alcoholic steatohepatitis, and related cardiometabolic disorders. The available clinical data demonstrate that the best GLP-1R agonists are not yet competitive with bariatric surgery, emphasizing the need to further improve the efficacy of current medical therapy.. In this article, we discuss data highlighting the physiological and pharmacological attributes of potential peptide and non-peptide partners, exemplified by amylin, glucose-dependent insulinotropic polypeptide (GIP), and steroid hormones. We review the progress, limitations, and future considerations for translating findings from preclinical experiments to competitive efficacy and safety in humans with type 2 diabetes and obesity.. Multiple co-agonist combinations exhibit promising clinical efficacy, notably tirzepatide and investigational amylin combinations. Simultaneously, increasing doses of GLP-1R agonists such as semaglutide produces substantial weight loss, raising the bar for the development of new unimolecular co-agonists. Collectively, the available data suggest that new co-agonists with robust efficacy should prove superior to GLP-1R agonists alone to treat metabolic disorders.

One of the effective and consistent ways to achieve glycaemic control for patients with type 2 diabetes mellitus (T2DM) is once-daily basal insulin. But it is also associated with adverse outcomes such as hypoglycaemia. Dulaglutide, a novel long-acting GLP-1 receptor agonist, may be a more suitable therapy. The present meta-analysis aims to assess the efficacy and safety of once-weekly glucagon-like peptide-1 receptor agonist dulaglutide compared with insulin glargine for the treatment of T2DM.. We searched PubMed, Embase and Cochrane Library from inception to December 2020. Randomized clinical trials comparing dulaglutide with insulin glargine in adults with T2DM were included. Revman5.2 software was used for meta-analysis.. We included 5 studies with 3383 randomized participants. Compared with insulin glargine, dulaglutide 1.5 mg led to greater mean HbA1c reduction (MD = -0.33%, 95% CI = -0.52, -0.15) whereas dulaglutide 0.75 mg did not (MD = -0.21%, 95% CI = -0.43, 0.01). Body weight loss was seen with dulaglutide whereas weight gain was seen with insulin glargine. The risk of hypoglycaemia was lower in dulaglutide 0.75 mg and 1.5 mg groups than in insulin glargine group,whereas dulaglutide had a statistically higher gastrointestinal adverse events incidence than insulin glargine.. Compared with insulin glargine, dulaglutide may serve as an effective alternative to provide improvement in glycaemic control with weight loss and less hypoglycaemia in patients with T2DM. It may be a more suitable therapy instead of basal insulin.

Obesity is a chronic disease associated with many complications. Weight loss of 5-15% can improve many obesity-related complications. Despite the benefits of weight reduction, there are many challenges in losing weight and maintaining long-term weight loss. Pharmacotherapy can help people with obesity achieve and maintain their target weight loss, thereby reducing the risk of obesity-related complications. The prevalence of obesity in the USA has been increasing over the past few decades, and despite the availability of approved anti-obesity medications (AOMs), people with obesity may not be accessing or receiving treatment at levels consistent with the disease prevalence. Reasons for low levels of initiation and long-term use of AOMs may include reluctance of public health and medical organizations to recognize obesity as a disease, lack of reimbursement, provider inexperience, and misperceptions about the efficacy and safety of available treatments. This article aims to inform primary care providers about the mechanism of action of one class of AOMs, glucagon-like peptide 1 receptor agonists (GLP-1RAs), in weight loss and longer-term maintenance of weight loss, and the efficacy and safety of this treatment class. GLP-1RA therapy was initially developed to treat type 2 diabetes. Owing to their effectiveness in reducing body weight, once-daily subcutaneous administration of liraglutide 3.0 mg has been approved, and once-weekly subcutaneous administration of semaglutide 2.4 mg is being investigated in phase III trials, for obesity management. Considerations regarding adverse effects and contraindications for different drug classes are provided to help guide treatment decision-making when considering pharmacotherapy for weight management in patients with obesity.. Obesity is a growing public health issue that increases the risk of developing heart disease, type 2 diabetes, and osteoarthritis. Weight loss can reduce the risk of developing these health problems but, despite this, levels of obesity remain high. Achieving and maintaining weight loss is challenging for many individuals. There is therefore a need for some patients to take medications to help them lose weight and prevent weight regain. Glucagon-like peptide 1 receptor agonists (GLP-1RAs) are a type of medication originally developed to treat type 2 diabetes, but are now being used for the treatment of obesity because they are effective at helping people to lose weight. One GLP-1RA, liraglutide, has been approved to treat obesity, and another, semaglutide, is in clinical trials. GLP-1RAs work by reducing the appetite and feelings of hunger, slowing the release of food from the stomach, and increasing feelings of fullness after eating. Most people can tolerate GLP-1RAs well. The most common side effects (nausea, vomiting, and diarrhea) are usually mild and occur in the first few weeks of treatment, reducing over time. Because of the difficulties many people face in maintaining weight loss, lifelong treatment may be needed. In clinical trials, GLP-1RAs were well tolerated and effective at helping people prevent weight regain, and may be a good option for long-term weight control and lowering patients’ chances of serious health problems.

As the cornerstone of type 2 diabetes (T2D) management within the community, primary care providers are now faced with the challenge of not only managing diabetes itself, but also preventing hypoglycemia and weight gain associated with intensive disease management, and reducing cardiovascular risk. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are well established as efficacious treatments for T2D, and the safety/tolerability profile of this drug class is well defined. However, despite their beneficial effects, GLP-1RAs are under-utilized, highlighting the need for novel approaches to increase their use in primary care. Oral semaglutide is the first oral GLP-1RA approved for the treatment of T2D, offering glucose lowering and body weight loss, a low risk of hypoglycemia, and no increase in cardiovascular risk. Oral semaglutide represents an additional treatment option for patients not achieving their glycemic goal despite treatment with metformin, either alone or with other hypoglycemic agents. Oral semaglutide has the potential to increase usage of GLP-1RAs in the primary care setting by addressing clinician and patient concerns about injections, and may facilitate earlier initiation of GLP-1RA therapy in T2D. Due to the formulation of oral semaglutide, clinicians need to be aware of specific considerations in order to ensure optimal use. Such considerations include dosing conditions and use of concomitant medications. This article provides practical guidance on the use of oral semaglutide in the primary care setting, based on evidence from clinical studies, including the phase 3a PIONEER program, and the authors' clinical experience.

Over recent decades, an improved understanding of the pathophysiology of type 2 diabetes mellitus (T2DM) and glucose regulation has led to innovative research and new treatment paradigms. The discovery of the gut peptide glucagon-like peptide-1 (GLP-1) and its role in glucose regulation paved the way for the class of GLP-1 receptor agonist compounds, or GLP-1RAs. The long-acting GLP-1RAs (dulaglutide, exenatide extended-release, liraglutide, semaglutide [injectable and oral]) are classified as such based on a minimum 24-hour duration of clinically relevant effects after administration. In phase 3 clinical trial programs of long-acting GLP-1RAs, A1C typically was reduced in the range of 1% to 1.5%, with reductions close to 2% in some studies. GLP-1RAs when used alone (without sulfonylureas or insulin) have a low risk of hypoglycemia because, like endogenous GLP-1, their insulinotropic effects are glucose-dependent. In addition to local actions in the gastrointestinal (GI) tract, GLP-1RAs stimulate receptors in the central nervous system to increase satiety, resulting in weight loss. All long-acting GLP-1RAs have, at minimum, been shown to be safe and not increase cardiovascular (CV) risk and most (liraglutide, semaglutide injectable, dulaglutide, albiglutide) have been shown in CV outcomes trials (CVOTs) to significantly reduce the risk of major cardiac adverse events. The class has good tolerability overall, with generally transient GI adverse events being most common. The weekly injectable agents offer scheduling convenience and may promote treatment adherence. One long-acting GLP-1RA is available as an oral daily tablet, which may be preferable for some patients and providers.

The glucagon-like peptide-1 (GLP-1) receptor agonists (RA) have increasingly gained prominence in the treatment of type 2 diabetes (T2D) based on their glycemic benefits and favorable body weight and cardiorenal effects. Despite this, continued development of therapeutics with superior efficacy is important to help address persistent challenges in the attainment of metabolic goals in many patients with T2D.. Tirzepatide is an unimolecular dual glucose-dependent insulinotropic polypeptide (GIP)/GLP-1 RA in development for the treatment of T2D. This review summarizes key characteristics of tirzepatide and Phase 1 and Phase 2 clinical trial efficacy and safety results. Additionally, it provides an overview of the ongoing Phase 3 clinical trial program in T2D and briefly summarizes recently initiated studies in patients with obesity and nonalcoholic steatohepatitis. Information in this review comes primarily from published clinical trials, manufacturer's websites, and ClinicalTrials.gov.. Based on data from Phase 2 trials, tirzepatide has the potential to be the most efficacious therapy in T2D with respect to both glucose and body weight control. Data from the ongoing Phase 3 clinical trial program should start to become available in late 2020 and will determine the future course of this promising therapeutic agent.

To review the evolution and advancement of GLP-1 receptor agonist (GLP-1RA) therapy, through the lens of randomised controlled trials, from differentiating characteristics, efficacy, safety, tolerability, and cardiovascular outcomes, to evidence gaps and next steps.. Clinical review of published phase 3 or later RCT data studying efficacy, safety, and outcomes of approved GLP-1 RA therapies.. Through a wealth of studies, including both placebo-controlled and active-controlled studies, GLP-1 RAs have demonstrated high glycemic efficacy and ability to facilitate weight loss, with minimal risk of hypoglycemia, potential to restore beta cell function, and evidence for improved cardiovascular outcomes in those at risk.. Over a decade of clinical studies have established the unique contributions of GLP-1 RAs in the treatment of diabetes. Individual differences between the different GLP-1 RAs, in delivery, pharmacokinetic and clinical effects, exist, allowing for tailored approaches to clinical care. The strength of evidence generated through RCTs, both short-term and long-term studies, will continue to evolve and inform our current paradigms in diabetes care.

To review efficacy and safety of the glucagon-like peptide-1 receptor agonist (GLP-1 RA) semaglutide for type 2 diabetes (T2D).. A literature search of PubMed/MEDLINE and EMBASE using the term semaglutide was completed through April 2018. A search of clinicaltrials.gov was also conducted.. English-language studies assessing the efficacy and/or safety of semaglutide were evaluated.. Semaglutide is a newly approved GLP-1 RA for the treatment of T2D. Administered once weekly at a dose of 0.5 or 1 mg, it has been compared with placebo, sitagliptin, insulin glargine, a combination of oral antidiabetic therapies, and 2 GLP-1 RAs, exenatide ER and dulaglutide, and demonstrated greater efficacy compared with these therapies. Published data from studies ranging from 30 to 104 weeks duration demonstrate efficacy with decreases in hemoglobin A1C (A1C) ranging from 1.1% to 2.2%. Studies show reductions in weight from 1.4 to 6.5 kg. Semaglutide demonstrated a reduction in the composite outcome of cardiovascular (CV) death, nonfatal myocardial infarction, or nonfatal stroke compared with placebo in patients at high risk of CV events (hazard ratio = 0.74; P = 0.02). Common adverse effects include nausea, vomiting, and diarrhea as seen with other GLP-1 RAs. Relevance to Patient Care and Clinical Practice: Semaglutide represents an attractive GLP-1 RA considering its A1C and weight reduction. It provides patient convenience and high patient satisfaction.. Semaglutide is an appealing option for the treatment of T2D as a once-weekly GLP-1 RA with established glycemic, CV, and weight benefits.

Once-weekly glucagon-like peptide-1 receptor agonists (GLP-1RAs) have shown promising results in the treatment of type 2 diabetes. Herein, we compared the efficacy and safety of once-weekly GLP-1RAs with exenatide and liraglutide separately.. We systematically surveyed the pertinent literature using various databases. The randomised controlled trials that compared once-weekly GLP-1RAs with exenatide and liraglutide in type 2 diabetes were included. Our main end-points were control of glycaemia, body weight, hypoglycaemia and gastrointestinal adverse events (AEs).. Our analysis included eight trials involving 5531 patients. Exenatide-long-acting release (LAR), dulaglutide and taspoglutide were more effective than twice-daily exenatide in reducing glycosylated haemoglobin A1c (HbA1c) and fasting blood glucose (FBG) levels and achieving HbA1c targets (< 7.0% and ≤ 6.5%). Liraglutide was as effective as dulaglutide and more effective than exenatide-LAR and albiglutide in controlling glycaemia. With regard to the effectiveness in decreasing body weight, exenatide-LAR, dulaglutide and taspoglutide were similar to exenatide whereas exenatide-LAR, dulaglutide and albiglutide were inferior to liraglutide. Once-weekly GLP-1RAs, exenatide and liraglutide resulted in a similar incidence of hypoglycaemia and of gastrointestinal, serious, or other AEs.. Once-weekly GLP-1RAs were more effective in controlling glycaemia and equally effective in decreasing body weight than twice-daily exenatide but were inferior to liraglutide in controlling these two parameters (dulaglutide was similar with liraglutide in controlling glycaemia). Once-weekly GLP-1RAs, exenatide and liraglutide had a similar risk of causing AEs.

Published data on the weight loss effects of glucagon-like peptide 1 (GLP-1) receptor agonists are reviewed, with a focus on data from clinical trials.. Obesity is a significant health problem in the United States (an estimated 69% of U.S. adults are overweight and nearly 35% are obese), and few drugs have proven safety and efficacy as adjuncts to lifestyle modification for weight management. GLP-1 receptor agonists are used for glycemic control in patients with type 2 diabetes and have been studied for their weight loss effects in patients with and without diabetes; these agents produce weight loss benefits through their effects on satiety and gastric emptying. In December 2014, the liraglutide product Saxenda (Novo Nordisk) became the first GLP-1 receptor agonist approved by the Food and Drug Administration (FDA) for use in long-term weight management. Results of clinical trials that evaluated the effects of GLP-1 receptor agonist therapy on weight and body mass index indicated outcomes comparable or superior to those achieved with the use of other antiobesity agents. As a class, GLP-1 receptor agonists have a generally more favorable safety profile than several other antiobesity agents; transient, mild-to-moderate gastrointestinal symptoms were the most frequently reported adverse effects in clinical trials.. Originally marketed for glycemic control in type 2 diabetes, GLP-1 receptor agonists have been found effective for weight reduction in patients with and without type 2 diabetes. Liraglutide is currently the only GLP-1 receptor agonist approved by FDA for obesity treatment.

More than 26 million people in the United States have type 2 diabetes mellitus (T2D). Many treatment options exist, but achieving long-term glycemic control in patients with T2D remains challenging. The glucagon-like peptide-1 receptor agonists (GLP-1 RAs) offer a treatment option that improves glycemic control and reduces weight, with a low risk of hypoglycemia. They have emerged as attractive options for the treatment of T2D, and significant advances and developments continue to be published regarding these agents. To identify relevant literature on emerging issues related to GLP-1 RAs, a search of the MEDLINE database was performed. Studies published in English evaluating the safety and efficacy of GLP-1 RAs were analyzed. Because of their advantages and unique mechanism of action, GLP-1 RAs are currently being studied in new clinical areas, including in combination with basal insulin, as adjunctive therapy in type 1 diabetes, and for weight loss. In addition, there are several emerging agents in development. Lixisenatide is a once-daily GLP-1 RA that targets postprandial glucose and may be most useful when added to basal insulin as an alternative to rapid-acting insulin. Albiglutide and dulaglutide are once-weekly GLP-1 RAs that may offer more convenient dosing. The most common adverse effects of all GLP-1 RA agents are gastrointestinal (e.g., nausea, diarrhea, and vomiting), but the rates of occurrence vary among agents. Due to the differences in pharmacokinetics, efficacy, rates of adverse effects, and administration requirements within the GLP-1 RA class, each agent should be evaluated independently. The future of GLP-1 RAs offers broader treatment options for T2D as well as potential in other treatment areas.

Obesity is a major risk factor for many leading causes of illness and death worldwide. Data are needed regarding the efficacy and safety of the nonpeptide glucagon-like peptide-1 (GLP-1) receptor agonist orforglipron as a once-daily oral therapy for weight reduction in adults with obesity.. In this phase 2, randomized, double-blind trial, we enrolled adults with obesity, or with overweight plus at least one weight-related coexisting condition, and without diabetes. Participants were randomly assigned to receive orforglipron at one of four doses (12, 24, 36, or 45 mg) or placebo once daily for 36 weeks. The percentage change from baseline in body weight was assessed at week 26 (primary end point) and at week 36 (secondary end point).. A total of 272 participants underwent randomization. At baseline, the mean body weight was 108.7 kg, and the mean body-mass index (the weight in kilograms divided by the square of the height in meters) was 37.9. At week 26, the mean change from baseline in body weight ranged from -8.6% to -12.6% across the orforglipron dose cohorts and was -2.0% in the placebo group. At week 36, the mean change ranged from -9.4% to -14.7% with orforglipron and was -2.3% with placebo. A weight reduction of at least 10% by week 36 occurred in 46 to 75% of the participants who received orforglipron, as compared with 9% who received placebo. The use of orforglipron led to improvement in all prespecified weight-related and cardiometabolic measures. The most common adverse events reported with orforglipron were gastrointestinal events, which were mild to moderate, occurred primarily during dose escalation, and led to discontinuation of orforglipron in 10 to 17% of participants across dose cohorts. The safety profile of orforglipron was consistent with that of the GLP-1 receptor agonist class.. Daily oral orforglipron, a nonpeptide GLP-1 receptor agonist, was associated with weight reduction. Adverse events reported with orforglipron were similar to those with injectable GLP-1 receptor agonists. (Funded by Eli Lilly; GZGI ClinicalTrials.gov number, NCT05051579.).

We evaluated gastrointestinal (GI) adverse events (AEs) with once-weekly semaglutide 2.4 mg in adults with overweight or obesity and their contribution to weight loss (WL).. AE analyses pooled data from the Semaglutide Treatment Effect in People With Obesity (STEP) 1-3 trials for participants randomized to 68 weeks of semaglutide 2.4 mg (n = 2117) or placebo (n = 1262). WL was analysed by presence/absence of GI AEs. Mediation analysis estimated WL effects mediated by and unrelated to GI AEs. GI tolerability with semaglutide 2.4 mg maintenance and cessation after dose escalation was evaluated using STEP 4 data among 803 participants tolerating 20 weeks of semaglutide run-in.. GI AEs were more common with semaglutide 2.4 mg than placebo, with most frequently nausea (43.9% vs. 16.1% of participants), diarrhoea (29.7% vs. 15.9%), vomiting (24.5% vs. 6.3%) and constipation (24.2% vs. 11.1%). Most GI AEs with semaglutide were non-serious (99.5% of AEs), mild-to-moderate (98.1%), transient and occurred most frequently during/shortly after dose escalation. Few semaglutide-treated participants (4.3%) permanently discontinued treatment for GI AEs. In STEP 1-3, mean WL with semaglutide 2.4 mg was similar in participants without (9.6%-17.1%) versus with GI AEs (11.4%-17.7%). Consistent with this observation, mediation analysis found that GI AEs contributed little to semaglutide-induced WL: of the additional 7.6%-14.4% WL with semaglutide versus placebo, <1 percentage point was mediated by GI AEs. In STEP 4, semaglutide 2.4 mg maintenance was well tolerated.. GI AEs were more common with semaglutide 2.4 mg than placebo, but typically mild-to-moderate and transient. Semaglutide-induced WL was largely independent of GI AEs.

Tirzepatide substantially reduced hemoglobin A1c (HbA1c) and body weight in subjects with type 2 diabetes (T2D) compared with the glucagon-like peptide 1 receptor agonist dulaglutide. Improved glycemic control was associated with lower circulating triglycerides and lipoprotein markers and improved markers of beta-cell function and insulin resistance (IR), effects only partially attributable to weight loss.. Assess plasma metabolome changes mediated by tirzepatide.. Phase 2b trial participants were randomly assigned to receive weekly subcutaneous tirzepatide, dulaglutide, or placebo for 26 weeks. Post hoc exploratory metabolomics and lipidomics analyses were performed.. Post hoc analysis.. 259 subjects with T2D.. Tirzepatide (1, 5, 10, 15 mg), dulaglutide (1.5 mg), or placebo.. Changes in metabolite levels in response to tirzepatide were assessed against baseline levels, dulaglutide, and placebo using multiplicity correction.. At 26 weeks, a higher dose tirzepatide modulated a cluster of metabolites and lipids associated with IR, obesity, and future T2D risk. Branched-chain amino acids, direct catabolic products glutamate, 3-hydroxyisobutyrate, branched-chain ketoacids, and indirect byproducts such as 2-hydroxybutyrate decreased compared to baseline and placebo. Changes were significantly larger with tirzepatide compared with dulaglutide and directly proportional to reductions of HbA1c, homeostatic model assessment 2-IR indices, and proinsulin levels. Proportional to metabolite changes, triglycerides and diglycerides were lowered significantly compared to baseline, dulaglutide, and placebo, with a bias toward shorter and highly saturated species.. Tirzepatide reduces body weight and improves glycemic control and uniquely modulates metabolites associated with T2D risk and metabolic dysregulation in a direction consistent with improved metabolic health.

Phase 3 trials have not compared semaglutide and liraglutide, glucagon-like peptide-1 analogues available for weight management.. To compare the efficacy and adverse event profiles of once-weekly subcutaneous semaglutide, 2.4 mg, vs once-daily subcutaneous liraglutide, 3.0 mg (both with diet and physical activity), in people with overweight or obesity.. Randomized, open-label, 68-week, phase 3b trial conducted at 19 US sites from September 2019 (enrollment: September 11-November 26) to May 2021 (end of follow-up: May 11) in adults with body mass index of 30 or greater or 27 or greater with 1 or more weight-related comorbidities, without diabetes (N = 338).. Participants were randomized (3:1:3:1) to receive once-weekly subcutaneous semaglutide, 2.4 mg (16-week escalation; n = 126), or matching placebo, or once-daily subcutaneous liraglutide, 3.0 mg (4-week escalation; n = 127), or matching placebo, plus diet and physical activity. Participants unable to tolerate 2.4 mg of semaglutide could receive 1.7 mg; participants unable to tolerate 3.0 mg of liraglutide discontinued treatment and could restart the 4-week titration. Placebo groups were pooled (n = 85).. The primary end point was percentage change in body weight, and confirmatory secondary end points were achievement of 10% or more, 15% or more, and 20% or more weight loss, assessed for semaglutide vs liraglutide at week 68. Semaglutide vs liraglutide comparisons were open-label, with active treatment groups double-blinded against matched placebo groups. Comparisons of active treatments vs pooled placebo were supportive secondary end points.. Of 338 randomized participants (mean [SD] age, 49 [13] years; 265 women [78.4%]; mean [SD] body weight, 104.5 [23.8] kg; mean [SD] body mass index, 37.5 [6.8]), 319 (94.4%) completed the trial, and 271 (80.2%) completed treatment. The mean weight change from baseline was -15.8% with semaglutide vs -6.4% with liraglutide (difference, -9.4 percentage points [95% CI, -12.0 to -6.8]; P < .001); weight change with pooled placebo was -1.9%. Participants had significantly greater odds of achieving 10% or more, 15% or more, and 20% or more weight loss with semaglutide vs liraglutide (70.9% of participants vs 25.6% [odds ratio, 6.3 {95% CI, 3.5 to 11.2}], 55.6% vs 12.0% [odds ratio, 7.9 {95% CI, 4.1 to 15.4}], and 38.5% vs 6.0% [odds ratio, 8.2 {95% CI, 3.5 to 19.1}], respectively; all P < .001). Proportions of participants discontinuing treatment for any reason were 13.5% with semaglutide and 27.6% with liraglutide. Gastrointestinal adverse events were reported by 84.1% with semaglutide and 82.7% with liraglutide.. Among adults with overweight or obesity without diabetes, once-weekly subcutaneous semaglutide compared with once-daily subcutaneous liraglutide, added to counseling for diet and physical activity, resulted in significantly greater weight loss at 68 weeks..

Obesity is a chronic disease that results in substantial global morbidity and mortality. The efficacy and safety of tirzepatide, a novel glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptor agonist, in people with obesity are not known.. In this phase 3 double-blind, randomized, controlled trial, we assigned 2539 adults with a body-mass index (BMI; the weight in kilograms divided by the square of the height in meters) of 30 or more, or 27 or more and at least one weight-related complication, excluding diabetes, in a 1:1:1:1 ratio to receive once-weekly, subcutaneous tirzepatide (5 mg, 10 mg, or 15 mg) or placebo for 72 weeks, including a 20-week dose-escalation period. Coprimary end points were the percentage change in weight from baseline and a weight reduction of 5% or more. The treatment-regimen estimand assessed effects regardless of treatment discontinuation in the intention-to-treat population.. At baseline, the mean body weight was 104.8 kg, the mean BMI was 38.0, and 94.5% of participants had a BMI of 30 or higher. The mean percentage change in weight at week 72 was -15.0% (95% confidence interval [CI], -15.9 to -14.2) with 5-mg weekly doses of tirzepatide, -19.5% (95% CI, -20.4 to -18.5) with 10-mg doses, and -20.9% (95% CI, -21.8 to -19.9) with 15-mg doses and -3.1% (95% CI, -4.3 to -1.9) with placebo (P<0.001 for all comparisons with placebo). The percentage of participants who had weight reduction of 5% or more was 85% (95% CI, 82 to 89), 89% (95% CI, 86 to 92), and 91% (95% CI, 88 to 94) with 5 mg, 10 mg, and 15 mg of tirzepatide, respectively, and 35% (95% CI, 30 to 39) with placebo; 50% (95% CI, 46 to 54) and 57% (95% CI, 53 to 61) of participants in the 10-mg and 15-mg groups had a reduction in body weight of 20% or more, as compared with 3% (95% CI, 1 to 5) in the placebo group (P<0.001 for all comparisons with placebo). Improvements in all prespecified cardiometabolic measures were observed with tirzepatide. The most common adverse events with tirzepatide were gastrointestinal, and most were mild to moderate in severity, occurring primarily during dose escalation. Adverse events caused treatment discontinuation in 4.3%, 7.1%, 6.2%, and 2.6% of participants receiving 5-mg, 10-mg, and 15-mg tirzepatide doses and placebo, respectively.. In this 72-week trial in participants with obesity, 5 mg, 10 mg, or 15 mg of tirzepatide once weekly provided substantial and sustained reductions in body weight.

No retrospective cohort study has assessed the effectiveness of semaglutide at doses used in randomized clinical trials to treat obesity (ie, 1.7 and 2.4 mg).. To study weight loss outcomes associated with semaglutide treatment at doses used in randomized clinical trials for patients with overweight or obesity.. This cohort study, conducted at a referral center for weight management, retrospectively collected data on the use of semaglutide for adults with overweight or obesity between January 1, 2021, and March 15, 2022, with a follow-up of up to 6 months. A total of 408 patients with a body mass index (BMI) of 27 or more were prescribed weekly semaglutide subcutaneous injections for 3 months or more. Patients with a history of bariatric procedures, taking other antiobesity medications, and with an active malignant neoplasm were excluded.. Weekly 1.7-mg or 2.4-mg semaglutide subcutaneous injections for 3 to 6 months.. The primary end point was the percentage of weight loss. Secondary end points were the proportion of patients achieving weight loss of 5% or more, 10% or more, 15% or more, and 20% or more after 3 and 6 months and the percentage of weight loss for patients with or without type 2 diabetes after 3 and 6 months.. The study included 175 patients (132 women [75.4%]; mean [SD] age, 49.3 [12.5] years; mean [SD] BMI, 41.3 [9.1]) in the analysis at 3 months and 102 patients at 6 months. The mean (SD) weight loss after 3 months was 6.7 (4.4) kg, equivalent to a mean (SD) weight loss of 5.9% (3.7%) (P < .001), and the mean (SD) weight loss after 6 months was 12.3 (6.6) kg, equivalent to a mean (SD) weight loss of 10.9% (5.8%) (P < .001 from baseline). Of the 102 patients who were followed up at 6 months, 89 (87.3%) achieved weight loss of 5% or more, 56 (54.9%) achieved weight loss of 10% or more, 24 (23.5%) achieved weight loss of 15% or more, and 8 (7.8%) achieved weight loss of 20% or more. Patients with type 2 diabetes had a lower mean (SD) percentage weight loss at 3 and 6 months compared with those without type 2 diabetes: 3.9% (3.1%) vs 6.3% (3.7%) at 3 months (P = .001) and 7.2% (6.3%) vs 11.8% (5.3%) at 6 months (P = .005).. The results of this cohort study suggest that weekly 1.7-mg and 2.4-mg doses of semaglutide were associated with weight loss similar to that seen in randomized clinical trials. Studies with longer periods of follow-up are needed to evaluate prolonged weight loss outcomes.

The STEP 5 trial assessed the efficacy and safety of once-weekly subcutaneous semaglutide 2.4 mg versus placebo (both plus behavioral intervention) for long-term treatment of adults with obesity, or overweight with at least one weight-related comorbidity, without diabetes. The co-primary endpoints were the percentage change in body weight and achievement of weight loss of ≥5% at week 104. Efficacy was assessed among all randomized participants regardless of treatment discontinuation or rescue intervention. From 5 October 2018 to 1 February 2019, 304 participants were randomly assigned to semaglutide 2.4 mg (n = 152) or placebo (n = 152), 92.8% of whom completed the trial (attended the end-of-trial safety visit). Most participants were female (236 (77.6%)) and white (283 (93.1%)), with a mean (s.d.) age of 47.3 (11.0) years, body mass index of 38.5 (6.9) kg m

People with overweight or obesity often suffer from associated cardiometabolic diseases and comorbidities. Current therapies for obesity include lifestyle intervention, bariatric surgery, and pharmacotherapy. The magnitude of weight loss achieved with these therapies can determine the level of improvement in various comorbidities. Once-weekly subcutaneous semaglutide 2.4 mg is a glucagon-like peptide-1 receptor agonist recently approved by the US Food and Drug Administration for the treatment of obesity. This article reviews data from the global phase 3 Semaglutide Treatment Effect in People with obesity (STEP) program, comparing the efficacy of once-weekly subcutaneous semaglutide 2.4 mg versus placebo for weight loss and improvements in cardiometabolic parameters across the STEP 1 to 5 trials. In STEP 1 to 3 and STEP 5, semaglutide led to greater reductions from baseline versus placebo in body weight, waist circumference, body mass index, systolic blood pressure (SBP), and diastolic blood pressure, as well as positive changes in glycated hemoglobin (HbA

Obesity is a global health challenge with few pharmacologic options. Whether adults with obesity can achieve weight loss with once-weekly semaglutide at a dose of 2.4 mg as an adjunct to lifestyle intervention has not been confirmed.. In this double-blind trial, we enrolled 1961 adults with a body-mass index (the weight in kilograms divided by the square of the height in meters) of 30 or greater (≥27 in persons with ≥1 weight-related coexisting condition), who did not have diabetes, and randomly assigned them, in a 2:1 ratio, to 68 weeks of treatment with once-weekly subcutaneous semaglutide (at a dose of 2.4 mg) or placebo, plus lifestyle intervention. The coprimary end points were the percentage change in body weight and weight reduction of at least 5%. The primary estimand (a precise description of the treatment effect reflecting the objective of the clinical trial) assessed effects regardless of treatment discontinuation or rescue interventions.. The mean change in body weight from baseline to week 68 was -14.9% in the semaglutide group as compared with -2.4% with placebo, for an estimated treatment difference of -12.4 percentage points (95% confidence interval [CI], -13.4 to -11.5; P<0.001). More participants in the semaglutide group than in the placebo group achieved weight reductions of 5% or more (1047 participants [86.4%] vs. 182 [31.5%]), 10% or more (838 [69.1%] vs. 69 [12.0%]), and 15% or more (612 [50.5%] vs. 28 [4.9%]) at week 68 (P<0.001 for all three comparisons of odds). The change in body weight from baseline to week 68 was -15.3 kg in the semaglutide group as compared with -2.6 kg in the placebo group (estimated treatment difference, -12.7 kg; 95% CI, -13.7 to -11.7). Participants who received semaglutide had a greater improvement with respect to cardiometabolic risk factors and a greater increase in participant-reported physical functioning from baseline than those who received placebo. Nausea and diarrhea were the most common adverse events with semaglutide; they were typically transient and mild-to-moderate in severity and subsided with time. More participants in the semaglutide group than in the placebo group discontinued treatment owing to gastrointestinal events (59 [4.5%] vs. 5 [0.8%]).. In participants with overweight or obesity, 2.4 mg of semaglutide once weekly plus lifestyle intervention was associated with sustained, clinically relevant reduction in body weight.

Weight loss improves cardiometabolic risk factors in people with overweight or obesity. Intensive lifestyle intervention and pharmacotherapy are the most effective noninvasive weight loss approaches.. To compare the effects of once-weekly subcutaneous semaglutide, 2.4 mg vs placebo for weight management as an adjunct to intensive behavioral therapy with initial low-calorie diet in adults with overweight or obesity.. Randomized, double-blind, parallel-group, 68-week, phase 3a study (STEP 3) conducted at 41 sites in the US from August 2018 to April 2020 in adults without diabetes (N = 611) and with either overweight (body mass index ≥27) plus at least 1 comorbidity or obesity (body mass index ≥30).. Participants were randomized (2:1) to semaglutide, 2.4 mg (n = 407) or placebo (n = 204), both combined with a low-calorie diet for the first 8 weeks and intensive behavioral therapy (ie, 30 counseling visits) during 68 weeks.. The co-primary end points were percentage change in body weight and the loss of 5% or more of baseline weight by week 68. Confirmatory secondary end points included losses of at least 10% or 15% of baseline weight.. Of 611 randomized participants (495 women [81.0%], mean age 46 years [SD, 13], body weight 105.8 kg [SD, 22.9], and body mass index 38.0 [SD, 6.7]), 567 (92.8%) completed the trial, and 505 (82.7%) were receiving treatment at trial end. At week 68, the estimated mean body weight change from baseline was -16.0% for semaglutide vs -5.7% for placebo (difference, -10.3 percentage points [95% CI, -12.0 to -8.6]; P < .001). More participants treated with semaglutide vs placebo lost at least 5% of baseline body weight (86.6% vs 47.6%, respectively; P < .001). A higher proportion of participants in the semaglutide vs placebo group achieved weight losses of at least 10% or 15% (75.3% vs 27.0% and 55.8% vs 13.2%, respectively; P < .001). Gastrointestinal adverse events were more frequent with semaglutide (82.8%) vs placebo (63.2%). Treatment was discontinued owing to these events in 3.4% of semaglutide participants vs 0% of placebo participants.. Among adults with overweight or obesity, once-weekly subcutaneous semaglutide compared with placebo, used as an adjunct to intensive behavioral therapy and initial low-calorie diet, resulted in significantly greater weight loss during 68 weeks. Further research is needed to assess the durability of these findings.. ClinicalTrials.gov Identifier: NCT03611582.

This trial assessed the efficacy and safety of the GLP-1 analogue once a week subcutaneous semaglutide 2·4 mg versus semaglutide 1·0 mg (the dose approved for diabetes treatment) and placebo for weight management in adults with overweight or obesity, and type 2 diabetes.. From June 4 to Nov 14, 2018, 1595 patients were screened, of whom 1210 were randomly assigned to semaglutide 2·4 mg (n=404), semaglutide 1·0 mg (n=403), or placebo (n=403) and included in the intention-to-treat analysis. Estimated change in mean bodyweight from baseline to week 68 was -9·6% (SE 0·4) with semaglutide 2·4 mg vs -3·4% (0·4) with placebo. Estimated treatment difference for semaglutide 2·4 mg versus placebo was -6·2 percentage points (95% CI -7·3 to -5·2; p<0·0001). At week 68, more patients on semaglutide 2·4 mg than on placebo achieved weight reductions of at least 5% (267 [68·8%] of 388 vs 107 [28·5%] of 376; odds ratio 4·88, 95% CI 3·58 to 6·64; p<0·0001). Adverse events were more frequent with semaglutide 2·4 mg (in 353 [87·6%] of 403 patients) and 1·0 mg (329 [81·8%] of 402) than with placebo (309 [76·9%] of 402). Gastrointestinal adverse events, which were mostly mild to moderate, were reported in 256 (63·5%) of 403 patients with semaglutide 2·4 mg, 231 (57·5%) of 402 with semaglutide 1·0 mg, and 138 (34·3%) of 402 with placebo.. In adults with overweight or obesity, and type 2 diabetes, semaglutide 2·4 mg once a week achieved a superior and clinically meaningful decrease in bodyweight compared with placebo.. Novo Nordisk.

The effect of continuing vs withdrawing treatment with semaglutide, a glucagon-like peptide 1 receptor agonist, on weight loss maintenance in people with overweight or obesity is unknown.. To compare continued once-weekly treatment with subcutaneous semaglutide, 2.4 mg, with switch to placebo for weight maintenance (both with lifestyle intervention) in adults with overweight or obesity after a 20-week run-in with subcutaneous semaglutide titrated to 2.4 mg weekly.. Randomized, double-blind, 68-week phase 3a withdrawal study conducted at 73 sites in 10 countries from June 2018 to March 2020 in adults with body mass index of at least 30 (or ≥27 with ≥1 weight-related comorbidity) and without diabetes.. A total of 902 participants received once-weekly subcutaneous semaglutide during run-in. After 20 weeks (16 weeks of dose escalation; 4 weeks of maintenance dose), 803 participants (89.0%) who reached the 2.4-mg/wk semaglutide maintenance dose were randomized (2:1) to 48 weeks of continued subcutaneous semaglutide (n = 535) or switched to placebo (n = 268), plus lifestyle intervention in both groups.. The primary end point was percent change in body weight from week 20 to week 68; confirmatory secondary end points were changes in waist circumference, systolic blood pressure, and physical functioning (assessed using the Short Form 36 Version 2 Health Survey, Acute Version [SF-36]).. Among 803 study participants who completed the 20-week run-in period (with a mean weight loss of 10.6%) and were randomized (mean age, 46 [SD, 12] years; 634 [79%] women; mean body weight, 107.2 kg [SD, 22.7 kg]), 787 participants (98.0%) completed the trial and 741 (92.3%) completed treatment. With continued semaglutide, mean body weight change from week 20 to week 68 was -7.9% vs +6.9% with the switch to placebo (difference, -14.8 [95% CI, -16.0 to -13.5] percentage points; P < .001). Waist circumference (-9.7 cm [95% CI, -10.9 to -8.5 cm]), systolic blood pressure (-3.9 mm Hg [95% CI, -5.8 to -2.0 mm Hg]), and SF-36 physical functioning score (2.5 [95% CI, 1.6-3.3]) also improved with continued subcutaneous semaglutide vs placebo (all P < .001). Gastrointestinal events were reported in 49.1% of participants who continued subcutaneous semaglutide vs 26.1% with placebo; similar proportions discontinued treatment because of adverse events with continued semaglutide (2.4%) and placebo (2.2%).. Among adults with overweight or obesity who completed a 20-week run-in period with subcutaneous semaglutide, 2.4 mg once weekly, maintaining treatment with semaglutide compared with switching to placebo resulted in continued weight loss over the following 48 weeks..

Tirzepatide is a dual glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 (GLP-1) receptor agonist that is under development for the treatment of type 2 diabetes. The efficacy and safety of once-weekly tirzepatide as compared with semaglutide, a selective GLP-1 receptor agonist, are unknown.. In an open-label, 40-week, phase 3 trial, we randomly assigned 1879 patients, in a 1:1:1:1 ratio, to receive tirzepatide at a dose of 5 mg, 10 mg, or 15 mg or semaglutide at a dose of 1 mg. At baseline, the mean glycated hemoglobin level was 8.28%, the mean age 56.6 years, and the mean weight 93.7 kg. The primary end point was the change in the glycated hemoglobin level from baseline to 40 weeks.. The estimated mean change from baseline in the glycated hemoglobin level was -2.01 percentage points, -2.24 percentage points, and -2.30 percentage points with 5 mg, 10 mg, and 15 mg of tirzepatide, respectively, and -1.86 percentage points with semaglutide; the estimated differences between the 5-mg, 10-mg, and 15-mg tirzepatide groups and the semaglutide group were -0.15 percentage points (95% confidence interval [CI], -0.28 to -0.03; P = 0.02), -0.39 percentage points (95% CI, -0.51 to -0.26; P<0.001), and -0.45 percentage points (95% CI, -0.57 to -0.32; P<0.001), respectively. Tirzepatide at all doses was noninferior and superior to semaglutide. Reductions in body weight were greater with tirzepatide than with semaglutide (least-squares mean estimated treatment difference, -1.9 kg, -3.6 kg, and -5.5 kg, respectively; P<0.001 for all comparisons). The most common adverse events were gastrointestinal and were primarily mild to moderate in severity in the tirzepatide and semaglutide groups (nausea, 17 to 22% and 18%; diarrhea, 13 to 16% and 12%; and vomiting, 6 to 10% and 8%, respectively). Of the patients who received tirzepatide, hypoglycemia (blood glucose level, <54 mg per deciliter) was reported in 0.6% (5-mg group), 0.2% (10-mg group), and 1.7% (15-mg group); hypoglycemia was reported in 0.4% of those who received semaglutide. Serious adverse events were reported in 5 to 7% of the patients who received tirzepatide and in 3% of those who received semaglutide.. In patients with type 2 diabetes, tirzepatide was noninferior and superior to semaglutide with respect to the mean change in the glycated hemoglobin level from baseline to 40 weeks.

Cardiovascular disease (CVD) is a major cause of morbidity and mortality. Although it has been widely appreciated that obesity is a major risk factor for CVD, treatments that produce effective, durable weight loss and the impact of weight reduction in reducing cardiovascular risk have been elusive. Instead, progress in CVD risk reduction has been achieved through medications indicated for controlling lipids, hyperglycemia, blood pressure, heart failure, inflammation, and/or thrombosis. Obesity has been implicated as promoting all these issues, suggesting that sustained, effective weight loss may have independent cardiovascular benefit. GLP-1 receptor agonists (RAs) reduce weight, improve glycemia, decrease cardiovascular events in those with diabetes, and may have additional cardioprotective effects. The GLP-1 RA semaglutide is in phase 3 studies as a medication for obesity treatment at a dose of 2.4 mg subcutaneously (s.c.) once weekly. Semaglutide Effects on Heart Disease and Stroke in Patients with Overweight or Obesity (SELECT) is a randomized, double-blind, parallel-group trial testing if semaglutide 2.4 mg subcutaneously once weekly is superior to placebo when added to standard of care for preventing major adverse cardiovascular events in patients with established CVD and overweight or obesity but without diabetes. SELECT is the first cardiovascular outcomes trial to evaluate superiority in major adverse cardiovascular events reduction for an antiobesity medication in such a population. As such, SELECT has the potential for advancing new approaches to CVD risk reduction while targeting obesity.

Insulin-treated patients with type 2 diabetes (T2D) and obesity are challenged in achieving body weight stability or reduction, in addition to glycaemic control. Post-hoc analyses of body weight and insulin dose data from the AWARD-4 trial involved comparison of treatment with once-weekly dulaglutide 1.5 mg (N = 295) or 0.75 mg (N = 293) and treatment with daily insulin glargine (N = 296), each with prandial insulin lispro (± metformin).. Changes in weight and in the proportion of patients without weight gain or with weight loss of at least 3%, 5% or 10% or composites of HbA1c less than 7% without weight gain and weight loss of at least 3% after 52 weeks were compared between the dulaglutide (either dose) groups and the insulin glargine group, overall and by baseline BMI (<30, 30-<35, ≥35 kg/m. The following parameters were statistically significant (P < 0.01) in favour of the dulaglutide-treated groups, at lower mean total daily insulin doses, vs the insulin glargine group. The achieved targets were more pronounced with dulaglutide 1.5 mg than with insulin glargine: LSM weight change difference, -3.23 kg; proportion of patients without weight gain, 49.0% vs 19.0%; proportion of patients with weight loss ≥3%, 21.7% vs 5.7% or with weight loss ≥5%, 10.5% vs 2.4%; proportion of patients with HbA1c <7% without weight gain, 26.2% vs 7.9%; proportion of patients with HbA1c <7% and weight loss ≥3%, 11.9% vs 1.4%, respectively. Treatment effect for these parameters was not significantly different across BMI categories.. Larger proportions of patients in late-stage T2D needing treatment intensification achieved glycemic control without weight gain or with weight loss at lower insulin doses with once-weekly dulaglutide plus daily prandial insulin than with a basal-bolus insulin regimen, overall and across all three BMI subgroups.

The Impact of Weight on Quality of Life-Lite (IWQOL-Lite) is widely used in evaluations of weight-loss interventions, including pharmaceutical trials. Because this measure was developed using input from individuals undergoing intensive residential treatment, the IWQOL-Lite may include concepts not relevant to clinical trial populations and may be missing concepts that are relevant to these populations. An alternative version, the IWQOL-Lite Clinical Trials Version (IWQOL-Lite-CT), was developed and validated according to the US Food and Drug Administration's (FDA's) guidance on patient-reported outcomes. Psychometric analyses were conducted to validate the IWQOL-Lite-CT using data from two randomized trials (NCT02453711 and NCT02906930) that included individuals with overweight/obesity, with and without type 2 diabetes. Additional measures included the SF-36, global items, weight and body mass index. The IWQOL-Lite-CT is a 20-item measure with two primary domains (Physical [seven items] and Psychosocial [13 items]). A five-item Physical Function composite and Total score were also supported. Cronbach's alpha and intraclass correlation coefficients exceeded 0.77 at each time point; patterns of construct validity correlations were consistent with hypotheses; and scores demonstrated treatment benefit. The IWQOL-Lite-CT is appropriate for assessing weight-related physical and psychosocial functioning in populations commonly targeted for obesity clinical trials. Qualification from the FDA is being sought for use of the IWQOL-Lite-CT in clinical trials to support product approval and labelling claims.

Dulaglutide, a once weekly GLP-1 receptor agonist, is approved at two doses (1.5 and 0.75 mg) for treatment of type 2 diabetes (T2D). Two higher doses of dulaglutide (3.0 and 4.5 mg) were evaluated for safety and efficacy to determine whether these doses warrant further study for improved control of glucose and body weight.. This 18-week, double-blind, phase 2 trial randomized 318 patients with T2D using ≥1500 mg metformin, to receive subcutaneous injection of placebo (n = 82), dulaglutide 1.5 mg (n = 81), dulaglutide 3.0 mg (n = 79) or dulaglutide 4.5 mg (n = 76). The primary objective was superiority of dulaglutide doses over placebo in reduction of HbA1c at 18 weeks. Secondary objectives included superiority of dulaglutide over placebo in change from baseline in body weight and fasting serum glucose (FSG) at 18 weeks. Investigational doses of dulaglutide were compared to the 1.5 mg dose as an exploratory objective.. HbA1c reduction at 18 weeks was significantly greater with dulaglutide vs placebo (placebo, -0.44% ± 0.10% [-4.8 ± 1.1 mmol/mol]; dulaglutide 1.5 mg, -1.23% ± 0.10% [-13.5 ± 1.1 mmol/mol]; dulaglutide 3.0 mg, -1.31% ± 0.10% [-14.3 ± 1.1 mmol/mol]; dulaglutide 4.5 mg, -1.40% ± 0.10% [-15.3 ± 1.1 mmol/mol]; P < 0.001, each dose), as were changes in body weight (placebo, -1.6 ± 0.39 kg; dulaglutide 1.5 mg, -2.8 ± 0.39 kg; dulaglutide 3.0 mg, -3.9 ± 0.39 kg; dulaglutide 4.5 mg, -4.1 ± 0.41 kg; P < 0.001, each dose). All three dulaglutide doses significantly reduced FSG from baseline (1.5 mg, -36.2 ± 4.7 mg/dL [-2.0 ± 0.3 mmol/L]; 3.0 mg, -34.5 ± 4.5 mg/dL [-1.9 ± 0.3 mmol/L]; 4.5 mg, -38.0 ± 4.7 mg/dL [-2.1 ± 0.3 mmol/L]) vs placebo (-12.4 ± 4.5 mg/dL [-0.7 ± 0.3 mmol/L]) (P < 0.001, all). Safety profiles of the higher doses were consistent with the established safety profile for dulaglutide. Gastrointestinal events were mostly mild to moderate, and was dose-related for nausea.. All three dulaglutide doses were superior to placebo in improving glycaemic control and reducing body weight in participants with T2D using metformin. The potential for doses of dulaglutide of 3.0 and 4.5 mg to provide additional glycaemic benefit and weight reduction with an acceptable safety profile, compared with the 1.5 mg dose, warrants further study in a phase 3 trial.

To investigate treatment satisfaction with semaglutide, a once-weekly glucagon-like peptide-1 receptor agonist, versus placebo/active comparators in the SUSTAIN clinical trial programme.. In SUSTAIN 2-5 and 7, the Diabetes Treatment Satisfaction Questionnaire was used to evaluate patient-perceived treatment satisfaction, hyperglycaemia and hypoglycaemia. Post hoc subgroup analyses were conducted to explore the effects of gastrointestinal adverse events (GI AEs), weight loss (≥5%) or achieving glycaemic (HbA1c < 7%) targets on treatment satisfaction.. Overall treatment satisfaction increased from baseline to end of treatment with all treatments across trials. Improvements were significantly greater with semaglutide versus comparators/placebo in SUSTAIN 2-5 (all P < 0.05), and generally greater in patients who achieved versus did not achieve weight loss and glycaemic targets, often with greater improvements with semaglutide 1.0 mg versus comparator/placebo in both weight loss groups. In SUSTAIN 7, improvements in overall treatment satisfaction were generally similar between semaglutide and dulaglutide, irrespective of weight loss or glycaemic control. In SUSTAIN 7, changes in overall treatment satisfaction score were generally lower in patients with versus without GI AEs at week 16 (except dulaglutide 0.75 mg), but similar by week 40. Perceived hyperglycaemia was significantly reduced from baseline to end of treatment with semaglutide versus all comparators/placebo (all P < 0.05). No differences between treatments were observed for perceived hypoglycaemia.. Semaglutide was associated with significantly greater (SUSTAIN 2-5) or similar (SUSTAIN 7) improvements in overall treatment satisfaction versus comparators/placebo. Improvements in overall treatment satisfaction were generally greater in patients achieving versus not achieving treatment targets.

To assess the safety and efficacy of monotherapy with once-weekly subcutaneous (s.c.) semaglutide vs sitagliptin in Japanese people with type 2 diabetes (T2D).. In this phase IIIa randomized, open-label, parallel-group, active-controlled, multicentre trial, Japanese adults with T2D treated with diet and exercise only or oral antidiabetic drug monotherapy (washed out during the run-in period) received once-weekly s.c. semaglutide (0.5 or 1.0 mg) or once-daily oral sitagliptin 100 mg. The primary endpoint was number of treatment-emergent adverse events (TEAEs) after 30 weeks.. Overall, 308 participants were randomized and exposed to treatment, with similar baseline characteristics across the groups. In total, 2.9% of participants in both the semaglutide 0.5 mg and the sitagliptin group prematurely discontinued treatment, compared with 14.7% in the semaglutide 1.0 mg group. The majority of discontinuations in the semaglutide 0.5 and 1.0 mg groups were attributable to adverse events (AEs). More TEAEs were reported in semaglutide- vs sitagliptin-treated participants (74.8%, 71.6% and 66.0% in the semaglutide 0.5 mg, semaglutide 1.0 mg and sitagliptin groups, respectively). AEs were mainly mild to moderate. Gastrointestinal AEs, most frequently reported with semaglutide, diminished in frequency over time. The mean glycated haemoglobin (HbA1c [baseline 8.1%]) decreased by 1.9% and 2.2% with semaglutide 0.5 and 1.0 mg, respectively, vs 0.7% with sitagliptin (estimated treatment difference [ETD] vs sitagliptin -1.13%, 95% confidence interval [CI] -1.32; -0.94, and -1.44%, 95% CI -1.63; -1.24; both P < .0001). Body weight (baseline 69.3 kg) was reduced by 2.2 and 3.9 kg with semaglutide 0.5 and 1.0 mg, respectively (ETD -2.22 kg, 95% CI -3.02; -1.42 and -3.88 kg, 95% CI -4.70; -3.07; both P < .0001).. In Japanese people with T2D, more TEAEs were reported with semaglutide than with sitagliptin; however, the semaglutide safety profile was similar to that of other glucagon-like peptide-1 receptor agonists. Semaglutide significantly reduced HbA1c and body weight compared with sitagliptin.

To evaluate the efficacy and safety of dulaglutide 1.5 and 0.75 mg in patients with type 2 diabetes by subgroups of gender, duration of diabetes and baseline glycated haemoglobin (HbA1c) in the dulaglutide clinical development programme (AWARD-1 to -6 and -8 clinical trials).. Change in HbA1c was analysed by gender, duration of diabetes (<5, ≥5 years and <10, ≥10 years), and baseline HbA1c (<8.5%, ≥8.5%) in pooled and individual studies. Changes from baseline in weight, hypoglycaemia and gastrointestinal adverse events were evaluated for individual trials.. In the pooled analysis of patients treated with dulaglutide 1.5 mg at 6 months, the reductions in HbA1c from baseline were similar across gender (men: least squares [LS] mean -1.26% [95% confidence interval {CI} -1.36, -1.16]; women: LS mean -1.33% [95% CI -1.43, -1.24]) and among duration of diabetes subgroups (<5 years: LS mean -1.32% [95% CI -1.43, -1.22]; ≥5 and <10 years: LS mean -1.33% [95% CI -1.43, -1.22]; ≥10 years: -1.24% [95% CI -1.35, -1.14]). Patients with baseline HbA1c ≥8.5% had greater HbA1c reductions than patients with baseline HbA1c <8.5%, (≥8.5%: LS mean -1.86% [95% CI -1.97, -1.75]; <8.5%: LS mean -1.02% [95% CI -1.12, -0.93]). Reductions in fasting blood glucose (FBG) were consistent with HbA1c changes. Similar results were observed with dulaglutide 0.75 mg. In general, body weight changes were similar among duration of diabetes and in baseline HbA1c subgroups, respectively; women had a numerically greater weight loss or less weight gain than men with both dulaglutide doses. There was no clinically meaningful difference in hypoglycaemia trends by gender or duration of diabetes. Hypoglycaemia incidence and rate were generally lower in patients with baseline HbA1c ≥8.5% than in those with <8.5%, except for the AWARD-4 study (combination with mealtime insulin).. Across the AWARD studies, dulaglutide demonstrated significant improvements in glycaemic control irrespective of gender, duration of diabetes, or baseline HbA1c, with greater HbA1c and FBG reductions in patients with a higher baseline HbA1c. Dulaglutide was well tolerated, with a safety profile similar to other glucagon-like peptide-1 receptor agonists.

To evaluate the safety and efficacy of once-weekly subcutaneous semaglutide as monotherapy or combined with an oral antidiabetic drug (OAD) vs an additional OAD added to background therapy in Japanese people with type 2 diabetes (T2D) inadequately controlled on diet/exercise or OAD monotherapy.. In this phase III, open-label trial, adults with T2D were randomized 2:2:1 to semaglutide 0.5 mg or 1.0 mg, or one additional OAD (a dipeptidyl peptidase-4 inhibitor, biguanide, sulphonylurea, glinide, α-glucosidase inhibitor or thiazolidinedione) with a different mode of action from that of background therapy. The primary endpoint was number of adverse events (AEs) after 56 weeks.. Baseline characteristics were balanced between treatment arms (601 randomized). More AEs were reported in the semaglutide 0.5 mg (86.2%) and 1.0 mg (88.0%) groups than in the additional OAD group (71.7%). These were typically mild/moderate. Gastrointestinal AEs were most frequent with semaglutide, which diminished over time. The mean glycated haemoglobin (HbA1c) concentration (baseline 8.1%) was significantly reduced with semaglutide 0.5 mg and 1.0 mg vs additional OAD (1.7% and 2.0% vs 0.7%, respectively; estimated treatment difference [ETD] vs additional OAD -1.08% and -1.37%, both P < .0001). Body weight (baseline 71.5 kg) was reduced by 1.4 kg and 3.2 kg with semaglutide 0.5 mg and 1.0 mg, vs a 0.4-kg increase with additional OAD (ETD -1.84 kg and -3.59 kg; both P < .0001). For semaglutide-treated participants, >80% achieved an HbA1c concentration <7.0% (Japanese Diabetes Society target).. Semaglutide was well tolerated, with no new safety issues identified. Semaglutide treatment significantly reduced HbA1c and body weight vs additional OAD treatment in Japanese people with T2D.

To assess the effect of baseline body mass index (BMI) and the occurrence of nausea and/or vomiting on weight loss induced by semalgutide, a once-weekly glucagon-like peptide 1 analogue for the treatment of type 2 diabetes. Semaglutide demonstrated superior reductions in HbA1c and superior weight loss (by 2.3-6.3 kg) versus different comparators across the SUSTAIN 1 to 5 trials; the contributing factors to weight loss are not established.. Subjects with inadequately controlled type 2 diabetes (drug-naïve or on background treatment) were randomized to subcutaneous semaglutide 0.5 mg (excluding SUSTAIN 3), 1.0 mg (all trials), or comparator (placebo, sitagliptin, exenatide extended release or insulin glargine). Subjects were subdivided by baseline BMI and reporting (yes/no) of any nausea and/or vomiting. Change from baseline in body weight was assessed within each trial and subgroup. A mediation analysis separated weight loss into direct or indirect (mediated by nausea or vomiting) effects.. Clinically relevant weight-loss differences were observed across all BMI subgroups, with a trend towards higher absolute weight loss with higher baseline BMI. Overall, 15.2% to 24.0% and 21.5% to 27.2% of subjects experienced nausea or vomiting with semaglutide 0.5 and 1.0 mg, respectively, versus 6.0% to 14.1% with comparators. Only 0.07 to 0.5 kg of the treatment difference between semaglutide and comparators was mediated by nausea or vomiting (indirect effects).. In SUSTAIN 1 to 5, semaglutide-induced weight loss was consistently greater versus comparators, regardless of baseline BMI. The contribution of nausea or vomiting to this weight loss was minor.

Obesity is a major public health issue, and new pharmaceuticals for weight management are needed. Therefore, we evaluated the efficacy and safety of the glucagon-like peptide-1 (GLP-1) analogue semaglutide in comparison with liraglutide and a placebo in promoting weight loss.. We did a randomised, double-blind, placebo and active controlled, multicentre, dose-ranging, phase 2 trial. The study was done in eight countries involving 71 clinical sites. Eligible participants were adults (≥18 years) without diabetes and with a body-mass index (BMI) of 30 kg/m. Between Oct 1, 2015, and Feb 11, 2016, 957 individuals were randomly assigned (102-103 participants per active treatment group and 136 in the pooled placebo group). Mean baseline characteristics included age 47 years, bodyweight 111·5 kg, and BMI 39·3 kg/m. In combination with dietary and physical activity counselling, semaglutide was well tolerated over 52 weeks and showed clinically relevant weight loss compared with placebo at all doses..

The aim of this trial was to investigate the mechanism of action for body weight loss with semaglutide.. This randomised, double-blind, placebo-controlled, two-period crossover trial investigated the effects of 12 weeks of treatment with once-weekly subcutaneous semaglutide, dose-escalated to 1.0 mg, in 30 subjects with obesity. Ad libitum energy intake, ratings of appetite, thirst, nausea and well-being, control of eating, food preference, resting metabolic rate, body weight and body composition were assessed.. After a standardised breakfast, semaglutide, compared with placebo, led to a lower ad libitum energy intake during lunch (-1255 kJ; P  < .0001) and during the subsequent evening meal ( P  = .0401) and snacks ( P  = .0034), resulting in a 24% reduction in total energy intake across all ad libitum meals throughout the day (-3036 kJ; P  < .0001). Fasting overall appetite suppression scores were improved with semaglutide vs placebo, while nausea ratings were similar. Semaglutide was associated with less hunger and food cravings, better control of eating and a lower preference for high-fat foods. Resting metabolic rate, adjusted for lean body mass, did not differ between treatments. Semaglutide led to a reduction from baseline in mean body weight of 5.0 kg, predominantly from body fat mass.. After 12 weeks of treatment, ad libitum energy intake was substantially lower with semaglutide vs placebo with a corresponding loss of body weight observed with semaglutide. In addition to reduced energy intake, likely mechanisms for semaglutide-induced weight loss included less appetite and food cravings, better control of eating and lower relative preference for fatty, energy-dense foods.

We evaluated patient-reported outcome (PRO) measures from the Assessment of Weekly AdministRation of LY2189265 (dulaglutide) in Diabetes (AWARD) clinical trial programme for dulaglutide (1.5 mg and 0.75 mg) in patients with type 2 diabetes (T2D). The Impact of Weight on Self-Perception (IW-SP), Impact of Weight on Ability to Perform Physical Activities of Daily Living (APPADL), Impact of Weight on Quality of Life-Lite, EQ-5D, Diabetes Treatment Satisfaction Questionnaire (DTSQ), Diabetes Symptom Checklist-Revised and Adult Low Blood Sugar Survey were administered and analysed for changes from baseline in one or more AWARD studies. Significant within-group changes from baseline to the primary time point were observed for several PRO measures across all studies. Compared with insulin glargine, significantly greater improvements in the IW-SP score were observed with dulaglutide 1.5 mg and with both dulaglutide doses in the APPADL score. Both dulaglutide doses resulted in significantly greater improvement in DTSQ scores (all subscales) compared with exenatide. Dulaglutide 1.5 mg also resulted in significantly greater improvement on the DTSQ hyperglycaemia subscale compared with metformin. Overall, these PRO results suggest that dulaglutide is beneficial in the treatment of T2D.

The efficacy and tolerability of once weekly dulaglutide 0.75 mg in Japanese patients with type 2 diabetes (T2D) were evaluated by subgroups defined by key demographic characteristics. This post hoc analysis included data from patients who received dulaglutide 0.75 mg for up to 26 weeks in three phase 3 trials (one open-label, randomized; one double-blind and open-label, randomized; one open-label, nonrandomized). Patients were classified into subgroups on the basis of sex (male, female), age (<65, ≥65 years), body weight (<70, ≥70 kg), body mass index (BMI; <25, ≥25 kg/m(2)), duration of diabetes (<7, ≥7 years), HbA1c (≤8.5, >8.5%), use of concomitant sulfonylurea (yes, no), and use of concomitant biguanide (yes, no). Efficacy measures analyzed were changes from baseline in HbA1c and body weight and percentages of patients achieving HbA1c <7.0%. Safety measures analyzed were incidence of hypoglycemia and nausea and change from baseline in seated pulse rate. A total of 855 patients were analyzed. Once weekly dulaglutide 0.75 mg improved blood glucose control as measured by HbA1c regardless of patient characteristics; patients with higher baseline HbA1c values had greater improvements compared to patients with lower baseline values. Weight loss was greater in patients with lower baseline HbA1c and in patients taking concomitant biguanides. Concomitant use of sulfonylureas had the greatest effect on the incidence of hypoglycemia. Treatment of T2D with once weekly dulaglutide 0.75 mg for 26 weeks was associated with significant improvement in glycemic control irrespective of age, sex, duration of diabetes, body weight, BMI, or concomitant medication.

To assess the relationship between weight change and glycated haemoglobin (HbA1c) change in dulaglutide-treated patients by analysing data from six head-to-head phase III AWARD clinical trials.. At 26 weeks, the relationship between weight and HbA1c was analysed in each trial rather than by pooling data because of differences in design and background therapy. The effect of baseline characteristics was also evaluated with regard to weight and HbA1c response.. Across the studies, 87-97% and 83-95% of patients treated with dulaglutide 1.5 and 0.75 mg, respectively, had reductions in HbA1c levels, while 57-88% and 43-84% of patients treated with dulaglutide 1.5 and 0.75 mg, respectively, experienced weight loss. The majority (55-83%) of patients receiving dulaglutide 1.5 mg experienced weight loss and HbA1c reductions, while 41-79% of patients in the dulaglutide 0.75 mg arm lost weight and had reductions in HbA1c level. A weak and inconsistent correlation was observed between the changes in weight and HbA1c (range from -0.223 to 0.267) in patients treated with dulaglutide. The baseline characteristics of gender, age, duration of diabetes, HbA1c, body weight and BMI were not related to different combinations of weight and HbA1c responses.. Dulaglutide is an effective treatment option across the type 2 diabetes treatment spectrum. Dulaglutide showed dose-dependent effects on both weight loss and HbA1c reduction. These effects had a weak correlation and appeared to be independent.

The efficacy and safety of once-weekly dulaglutide 0.75 mg (dulaglutide) in Japanese patients with type 2 diabetes (T2D) were evaluated according to subgroups defined by concomitant oral hypoglycaemic agents. This exploratory analysis included data from a randomized, open-label, phase III study that compared dulaglutide with insulin glargine (glargine) (n = 361). The three subgroups were dulaglutide or glargine in combination with sulphonylurea (SU) alone, biguanide (BG) alone or SU and BG combined. There were no clinically relevant differences in glycated haemoglobin (HbA1c) changes among the three subgroups in the dulaglutide group; in the glargine group, a numerically greater reduction was observed in combination with BG alone compared to the other two groups (SU alone and SU + BG). Weight loss was observed with dulaglutide in combination with BG alone or with SU + BG. The incidence of adverse events among subgroups was significantly different in the glargine group but not in the dulaglutide group. Incidence of hypoglycaemia was highest in combination with SU for both treatments. For patients with T2D, dulaglutide added to concomitant BG may be more likely to result in weight loss than dulaglutide added to concomitant SU.

The aim of this post hoc analysis was to assess the efficacy and safety of once-weekly dulaglutide in Hispanic/Latino patients with type 2 diabetes (T2D) in phase 3 AWARD trials 1 to 6.. Hispanic/Latino data at Week 26 were pooled across studies for each dulaglutide dose to analyze the change from baseline in glycosylated hemoglobin (HbA1c), percent to HbA1c goal, and adverse events (AEs). Change from baseline in HbA1c, change from baseline in weight and hypoglycemia were analyzed by Hispanic/Latino and non-Hispanic/Latino subgroups for each study.. Of the 3,136 patients randomized to dulaglutide 1.5 or 0.75 mg, 949 were reported as having Hispanic/Latino ethnicity. Baseline characteristics were similar for Hispanic/Latino and overall populations, except there were slightly more Hispanic/Latino females and weight was slightly lower for Hispanic/Latino patients. Hispanic/Latino patients receiving dulaglutide 1.5 mg had a reduction in HbA1c of 1.25% (95% confidence interval [CI]: -1.35, -1.15); dulaglutide 0.75 mg had a reduction of 1.07% (95% CI: -1.18, -0.96). Reductions in HbA1c and percent to goal HbA1c <7% and ≤6.5% were similar between Hispanic/Latino patients and the overall population. Weight change and hypoglycemia were similar between Hispanic/Latino and non-Hispanic/Latino subgroups for all studies. Treatment-emergent AEs were consistent with the overall population.. Dulaglutide improved glycemic control with the potential for weight loss in Hispanic/Latino patients with T2D. Dulaglutide was well tolerated and had a low risk of hypoglycemia when used without insulin secretagogues or insulin. In the Hispanic/Latino population, dulaglutide efficacy and safety was consistent with that of the overall population..

To compare the once-weekly glucagon-like peptide-1 (GLP-1) receptor dulaglutide with the dipeptidyl peptidase-4 (DPP-4) inhibitor sitagliptin after 104 weeks of treatment.. This AWARD-5 study was a multicentre, double-blind trial that randomized participants to dulaglutide (1.5 or 0.75 mg) or sitagliptin 100 mg for 104 weeks or placebo (reported separately) for 26 weeks. Change in glycated haemoglobin (HbA1c) concentration from baseline was the primary efficacy measure. A total of 1098 participants with HbA1c concentrations ≥7.0% (≥53.0 mmol/mol) and ≤9.5% (≤80.3 mmol/mol) were randomized, and 657 (59.8%) completed the study. We report results for dulaglutide and sitagliptin at the final endpoint.. Changes in HbA1c at 104 weeks were (least squares mean ± standard error) -0.99 ± 0.06% (-10.82 ± 0.66 mmol/mol), -0.71 ± 0.07% (-7.76 ± 0.77 mmol/mol) and -0.32 ± 0.06% (-3.50 ± 0.66 mmol/mol) for dulaglutide 1.5 mg, dulaglutide 0.75 mg and sitagliptin, respectively (p < 0.001, both dulaglutide doses vs sitagliptin). Weight loss was greater with dulaglutide 1.5 mg (p < 0.001) and similar with 0.75 mg versus sitagliptin (2.88 ± 0.25, 2.39 ± 0.26 and 1.75 ± 0.25 kg, respectively). Gastrointestinal adverse events were more common with dulaglutide 1.5 and 0.75 mg versus sitagliptin (nausea 17 and 15% vs 7%, diarrhoea 16 and 12% vs 6%, vomiting 14 and 8% vs 4% respectively). Pancreatic, thyroid, cardiovascular and hypersensitivity safety were similar across groups.. Dulaglutide doses provided superior glycaemic control and dulaglutide 1.5 mg resulted in greater weight reduction versus sitagliptin at 104 weeks, with acceptable safety.

This study compared the efficacy and safety of once-weekly dulaglutide, a glucagon-like peptide-1 receptor agonist, with daily insulin glargine, both combined with maximally tolerated doses of metformin and glimepiride in patients with type 2 diabetes. The primary objective was noninferiority of dulaglutide 1.5 mg to glargine in the HbA1c change from baseline at 52 weeks.. In this 78-week, open-label study, 810 patients were randomized to dulaglutide 1.5 mg, dulaglutide 0.75 mg, or glargine.. The baseline mean ± SD HbA1c was 8.1 ± 1.0% (65.5 ± 10.8 mmol/mol). The least squares mean ± SE HbA1c change from baseline to the primary end point was -1.08 ± 0.06% (-11.8 ± 0.7 mmol/mol) for dulaglutide 1.5 mg, -0.76 ± 0.06% (-8.3 ± 0.7 mmol/mol) for dulaglutide 0.75 mg, and -0.63 ± 0.06% (-6.9 ± 0.7 mmol/mol) for glargine, with an end point mean ± SD dose of 29 ± 26 units (0.33 ± 0.24 units/kg), and a fasting plasma glucose (mean ± SD) of 118 ± 23 mg/dL from self-monitored plasma glucose. Statistical criteria for superiority were met with dulaglutide 1.5 mg and for noninferiority with dulaglutide 0.75 mg. More patients on dulaglutide 1.5 mg achieved HbA1c targets <7.0% (53 mmol/mol) versus glargine (P < 0.001). Body weight decreased with dulaglutide and increased with glargine. Total hypoglycemia rates were lower with dulaglutide; severe hypoglycemia was minimal. Increases in pancreatic enzymes were observed for dulaglutide. Incidence of nausea (15.4, 7.7, and 1.5%) and diarrhea (10.6, 9.2, and 5.7%) were more common with dulaglutide 1.5 mg and 0.75 mg than with glargine.. Once-weekly dulaglutide 1.5 mg, compared with daily insulin glargine without forced titration, demonstrated greater HbA1c reduction and weight loss, with a higher incidence of gastrointestinal adverse events and a lower risk of hypoglycemia.

To evaluate the efficacy and tolerability of once-weekly LY2189265 (LY), a novel glucagon-like peptide-1 (GLP-1) IgG4-Fc fusion protein, in patients with type 2 diabetes failing oral antihyperglycaemic medications (OAMs).. Placebo-controlled, double-blind study in 262 patients (mean age 57 ± 12 years; BMI 33.9 ± 4.1 kg/m(2); and glycosylated haemoglobin A1c (A1c) 8.24 ± 0.93%) receiving two OAMs. Patients were randomized to once-weekly subcutaneous injections of placebo or LY 0.5 mg for 4 weeks, then 1.0 mg for 12 weeks (LY 0.5/1.0); 1.0 mg for 16 weeks (LY 1.0/1.0); or 1.0 mg for 4 weeks, then 2.0 mg for 12 weeks (LY 1.0/2.0).. At week 16, A1c changes (least-squares mean ± standard error) were -0.24 ± 0.12, -1.38 ± 0.12, -1.32 ± 0.12 and -1.59 ± 0.12%, in the placebo, LY 0.5/1.0, LY 1.0/1.0 and LY 1.0/2.0 arms, respectively (all p < 0.001 vs. placebo). Both fasting (p < 0.001) and postprandial (p < 0.05) blood glucose decreased significantly compared to placebo at all LY doses. Weight loss was dose dependent and ranged from -1.34 ± 0.39 to -2.55 ± 0.40 kg at 16 weeks (all p < 0.05 vs. placebo). At the highest LY dosage, the most common adverse events were nausea (13.8%), diarrhoea (13.8%) and abdominal distension (13.8%). Hypoglycaemia was uncommon overall (≤0.8 episodes/patient/30 days) but more common with LY than placebo through the initial 4 weeks (p < 0.05). No differences in cardiovascular events or blood pressure were shown between treatments.. LY2189265, given to overweight/obese patients with type 2 diabetes for 16 weeks in combination with OAMs, was relatively well tolerated and significantly reduced A1c, blood glucose and body weight.

This study investigated the effect of subcutaneously administered oxyntomodulin on body weight in healthy overweight and obese volunteers. Participants self-administered saline or oxyntomodulin subcutaneously in a randomized, double-blind, parallel-group protocol. Injections were self-administered for 4 weeks, three times daily, 30 min before each meal. The volunteers were asked to maintain their regular diet and level of physical exercise during the study period. Subjects' body weight, energy intake, and levels of adipose hormones were assessed at the start and end of the study. Body weight was reduced by 2.3 +/- 0.4 kg in the treatment group over the study period compared with 0.5 +/- 0.5 kg in the control group (P = 0.0106). On average, the treatment group had an additional 0.45-kg weight loss per week. The treatment group demonstrated a reduction in leptin and an increase in adiponectin. Energy intake by the treatment group was significantly reduced by 170 +/- 37 kcal (25 +/- 5%) at the initial study meal (P = 0.0007) and by 250 +/- 63 kcal (35 +/- 9%) at the final study meal (P = 0.0023), with no change in subjective food palatability. Oxyntomodulin treatment resulted in weight loss and a change in the levels of adipose hormones consistent with a loss of adipose tissue. The anorectic effect was maintained over the 4-week period. Oxyntomodulin represents a potential therapy for obesity.

Escalating doses of insulin required with progression of type 2 diabetes may lead to weight gain. Weight loss associated with semaglutide may be beneficial. However, data on the use of semaglutide in patients requiring high daily doses of insulin are currently lacking.. The purpose of this project was to evaluate the impact of semaglutide on total daily dose (TDD) of insulin when initiated in patients with type 2 diabetes mellitus (T2DM) on high daily doses of insulin. Secondary objectives assessed included changes in weight, body mass index (BMI), blood pressure, heart rate, and diabetes and blood pressure medications.. This IRB exempt retrospective medical record review included patients with T2DM prescribed semaglutide and at least 100 units TDD of insulin between January 1, 2019, and December 31, 2019.. Of the 72 patients included, the TDD of insulin decreased from baseline to 6 months (183 ± 98 units and 143 ± 99 units,. Improvement in glycemic control occurred despite reductions in TDD of insulin. Improvements in A1c and body weight were clinically significant. This analysis adds to existing literature supporting the use of GLP-1 RAs in patients on high daily doses of insulin.

Higher doses of the glucagon-like peptide-1 agonist semaglutide and, more recently, tirzepatide, a dual glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 agonist showed a significant reduction in body weight in patients with type 2 diabetes mellitus. However, their comparative value for money for this indication is unclear. Therefore, we aimed to establish which provides better value for money.. We calculated the cost needed to treat to achieve a 1% reduction in body weight using high-dose tirzepatide (15 mg) versus semaglutide (2.4 mg). The body weight reductions were extracted from published results of SURMOUNT-1 and STEP 1 trials, respectively. In addition, we performed a scenario analysis to mitigate the primary differences between the two study populations. Drug costs were based on US GoodRx prices as of October 2022.. Using tirzepatide resulted in a weight loss of 17.8% (95% CI: 16.3%-19.3%) compared with 12.4% (95% CI: 11.5%-13.4%) for semaglutide. The total cost of 72 weeks of tirzepatide was estimated at $17 527 compared with $22 878 for 68 weeks of semaglutide. Accordingly, the cost needed to treat per 1% of body weight reduction with tirzepatide is estimated at $985 (95% CI: $908-$1075) compared with $1845 (95% CI: $1707-$1989) with semaglutide. Scenario analysis confirmed these findings.. Tirzepatide provides better value for money than semaglutide for weight reduction.

Glucagon-like peptide-1 (GLP-1) receptor agonists have a privileged place in the management of type 2 diabetes (T2D). They not only improve glucose control without inducing hypoglycaemia and trigger weight loss, but also protect against atherosclerotic cardiovascular disease. Increasing the dose of three of them (liraglutide, semaglutide, dulaglutide) allows better glycaemic results and of potential interest a greater weight reduction. Liraglutide at a daily dose of 3.0 mg and semaglutide at a weekly dose of 2.4 mg received the indication for the therapy of obesity. A recent innovation consists in the development of dual unimolecular agonists that target GLP-1 and GIP («glucose-dependent insulinotropic polypeptide») receptors (tirzepatide) or GLP-1 and glucagon receptors (cotadutide). Tirzepatide, in the SURPASS programme, showed impressive reductions in glycated haemoglobin level and body weight, greater than those observed with dulaglutide or semaglutide. Tirzepatide received the indication of the treatment of T2D and is currently tested in obesity (SURMOUNT programme). Interestingly, triagonists GIP/GLP-1/glucagon are currently developed for the management of T2D and obesity, with also perspectives for treating metabolic-associated fatty liver disease.. Les agonistes du glucagon-like peptide-1 (GLP-1) ont une place de choix dans la prise en charge des patients avec un diabète de type 2 (DT2). Non seulement ils améliorent le contrôle glycémique sans provoquer des hypoglycémies et font perdre du poids, mais ils protègent également contre les maladies cardiovasculaires athéromateuses. Une augmentation de la posologie de trois d’entre eux (liraglutide, sémaglutide, dulaglutide) a permis de meilleurs résultats glycémiques et surtout une plus grande perte pondérale. Le liraglutide, à la dose de 3,0 mg/jour, et le sémaglutide, à la dose de 2,4 mg/semaine, ont d’ailleurs reçu l’indication pour le traitement de l’obésité. Une innovation récente consiste dans le développement d’agonistes unimoléculaires doubles ciblant les récepteurs du GLP-1 et du GIP («glucose-dependent insulinotropic polypeptide») (tirzépatide) ou les récepteurs du GLP-1 et du glucagon (cotadutide). Le tirzépatide, dans le programme SURPASS, a montré des réductions importantes du taux d’hémoglobine glyquée et du poids corporel, supérieures à celles observées avec le dulaglutide ou le sémaglutide. Il a reçu l’indication du traitement du DT2 et est actuellement testé dans l’obésité (programme SURMOUNT). Des triagonistes GIP/GLP-1/glucagon sont également développés pour le traitement du DT2 et de l’obésité, avec des perspectives également dans la stéatopathie hépatique.

SURE Italy, a multicentre, prospective, open-label, observational, real-world study, investigated once-weekly semaglutide in patients with type 2 diabetes (T2D) in routine clinical practice.. Adults with T2D and ≥1 documented glycated haemoglobin (HbA1c) level within 12 weeks of semaglutide initiation were enrolled. The primary endpoint was change in HbA1c from baseline to end of study (EOS; ~30 weeks). Other endpoints included changes in body weight, waist circumference and patient-reported outcomes, and the proportion of patients achieving HbA1c <7.0% or <6.5%, weight loss ≥5% and a post-hoc composite endpoint (HbA1c reduction of ≥1%-point and weight loss ≥5%). These endpoints were reported for patients on semaglutide at EOS [effectiveness analysis set (EAS)]. Safety data were reported in the full analysis set.. Of 579 patients who initiated semaglutide (full analysis set), 491 completed the study on treatment (EAS). Mean baseline HbA1c was 8.0%, and 20.7% (120 of 579) of patients had HbA1c <7.0%. Mean semaglutide dose at EOS was 0.66 ± 0.28 mg. In the EAS, mean HbA1c and body weight decreased by 1.1%-point (95% confidence interval 1.20, 1.05; P < .0001) and 4.2 kg (95% confidence interval 4.63, 3.67; P < .0001), respectively. At EOS, 61.7% and 40.8% of patients achieved HbA1c <7.0% and <6.5%, respectively, 40.5% achieved weight loss ≥5% and 25.3% achieved the post-hoc composite endpoint. Patient-reported outcomes improved from baseline to EOS. No new safety concerns were identified.. In routine clinical practice in Italy, patients with T2D treated with once-weekly semaglutide for 30 weeks achieved clinically significant improvements in HbA1c, body weight and other outcomes.

We report a case in which the use of semaglutide for weight loss was associated with delayed gastric emptying and intraoperative pulmonary aspiration of gastric contents.. A 42-yr-old patient with Barrett's esophagus underwent repeat upper gastrointestinal endoscopy and ablation of dysplastic mucosa. Two months earlier, the patient had started weekly injections of semaglutide for weight loss. Despite having fasted for 18 hr, and differing from the findings of prior procedures, endoscopy revealed substantial gastric content, which was suctioned before endotracheal intubation. Food remains were removed from the trachea and bronchi using bronchoscopy. The patient was extubated four hours later and remained asymptomatic.. Patients using semaglutide and other glucagon-like peptide 1 agonists for weight management may require specific precautions during induction of anesthesia to prevent pulmonary aspiration of gastric contents.. RéSUMé: OBJECTIF: Nous rapportons un cas dans lequel l’utilisation de sémaglutide à des fins de perte de poids a été associée à un retard de vidange gastrique et à une aspiration pulmonaire peropératoire du contenu gastrique. CARACTéRISTIQUES CLINIQUES: Un patient de 42 ans souffrant d’un œsophage de Barrett a subi une cinquième endoscopie gastro-intestinale supérieure avec ablation de la muqueuse dysplasique. Deux mois plus tôt, le patient avait commencé à recevoir des injections hebdomadaires de sémaglutide pour perdre du poids. Bien qu’à jeun depuis 18 heures et à la différence des évaluations lors des interventions antérieures, l’endoscopie a révélé un contenu gastrique important, qui a été aspiré avant l’intubation endotrachéale. Les restes de nourriture ont été retirés de la trachée et des bronches par bronchoscopie. Le patient a été extubé quatre heures plus tard et est demeuré asymptomatique. CONCLUSION: Les patients utilisant du sémaglutide et d’autres agonistes du peptide analog au glucagon-1 pour la gestion du poids pourraient nécessiter des précautions spécifiques lors de l’induction de l’anesthésie pour empêcher l’aspiration pulmonaire du contenu gastrique.

The aim of this study was to compare the effectiveness of semaglutide versus liraglutide for treating post-metabolic and bariatric surgery (MBS) weight recurrence.. A retrospective analysis of 207 adults with post-MBS weight recurrence treated with semaglutide 1.0 mg weekly (n = 115) or liraglutide 3.0 mg daily (n = 92) at an academic center from January 1, 2015, through April 1, 2021, was conducted. The primary end point was percentage body weight change at 12 months of treatment with regimens containing semaglutide or liraglutide.. The mean sample age was 55.2 years; mean BMI was 40.4 kg/m. These results show that treatment regimens including semaglutide 1.0 mg weekly lead to superior weight loss compared with liraglutide 3.0 mg daily for treating post-MBS weight recurrence, regardless of procedure type or the magnitude of weight recurrence.

To investigate the changes of circulating levels of all proglucagon-derived peptides (PGDPs) in individuals with overweight or obesity receiving liraglutide (3 mg) or naltrexone/bupropion (32/360 mg), and to explore the association between induced changes in postprandial PGDP levels and body composition, as well as metabolic variables, after 3 and 6 months on treatment.. Seventeen patients with obesity or with overweight and co-morbidities, but without diabetes, were assigned to receive once-daily oral naltrexone/bupropion 32/360 mg (n = 8) or once-daily subcutaneous liraglutide 3 mg (n = 9). Participants were assessed before treatment initiation and after 3 and 6 months on treatment. At the baseline and 3-month visits, participants underwent a 3-hour mixed meal tolerance test to measure fasting and postprandial levels of PGDPs, C-peptide, hunger and satiety. Clinical and biochemical indices of metabolic function, magnetic resonance-assessed liver steatosis and ultrasound-assessed liver stiffness were measured at each visit.. Both medications improved body weight and composition, carbohydrate and lipid metabolism, and liver fat and function. Naltrexone/bupropion produced a weight-independent increase in the levels of proglucagon (P < .001) and decreases in glucagon-like peptide-2 (GLP-2), glucagon and the major proglucagon fragment (P ≤ .01), whereas liraglutide markedly upregulated total glucagon-like peptide-1 (GLP-1) levels in a weight-independent manner (P = .04), and similarly downregulated the major proglucagon fragment, GLP-2 and glucagon (P < .01). PGDP levels at the 3-month visit were positively and independently correlated with improvements in fat mass, glycaemia, lipaemia and liver function, and negatively with reductions in fat-free mass, at both the 3- and 6-month visits.. PGDP levels in response to liraglutide and naltrexone/bupropion are associated with improvements in metabolism. Our study provides support for the administration of the downregulated members of the PGDP family as replacement therapy (e.g. glucagon), in addition to the medications currently in use that induced their downregulation (e.g. GLP-1), and future studies should explore whether the addition of other PGDPs (e.g. GLP-2) could offer additional benefits.

To compare the efficacy of tirzepatide 10 and 15 mg with semaglutide 2.4 mg using an indirect treatment comparison.. Using SURMOUNT-1 and STEP 1 trial data, mean percentage change in body weight from baseline and odds ratio (OR) of achieving 5% or greater weight loss were compared between tirzepatide 10 and 15 mg at week 72 and semaglutide 2.4 mg at week 68 using matching-adjusted indirect comparison of the efficacy estimand. Sensitivity analyses were completed using different methods, including the Bucher method, also using different estimands and/or time points.. Greater reductions in percentage change in body weight were observed with tirzepatide 10 and 15 mg versus semaglutide 2.4 mg (tirzepatide 10 mg mean difference: -4.67% [95% CI -5.91%, -3.43%]; tirzepatide 15 mg mean difference: -5.92% [95% CI -7.16%, -4.68%]; both P < .001). Similarly, more participants achieved 5% or greater weight loss with tirzepatide 10 mg (OR 2.61 [95% CI 1.48, 4.57]; P < .001) and 15 mg (OR 2.75 [95% CI 1.57, 4.81]; P < .001) compared with semaglutide 2.4 mg. All sensitivity analyses were consistent, except for an OR of achieving 5% or greater weight loss with tirzepatide 10 mg using the Bucher method to analyse the treatment regimen estimand (P = .074).. Currently there are no direct comparisons of tirzepatide and semaglutide for weight management. Using the matching-adjusted indirect treatment comparison method to compare the efficacy of tirzepatide and semaglutide for chronic weight management, this analysis showed greater weight loss with tirzepatide 10 and 15 mg versus semaglutide 2.4 mg.

To determine the relationship between exposure and weight-loss trajectories for the glucagon-like peptide-1 analogue semaglutide for weight management.. Data from one 52-week, phase 2, dose-ranging trial (once-daily subcutaneous semaglutide 0.05-0.4 mg) and two 68-week phase 3 trials (once-weekly subcutaneous semaglutide 2.4 mg) for weight management in people with overweight or obesity with or without type 2 diabetes were used to develop a population pharmacokinetic (PK) model describing semaglutide exposure. An exposure-response model describing weight change was then developed using baseline demographics, glycated haemoglobin and PK data during treatment. The ability of the exposure-response model to predict 1-year weight loss based on weight data collected at baseline and after up to 28 weeks of treatment, was assessed using three independent phase 3 trials.. Based on population PK, exposure levels over time consistently explained the weight-loss trajectories across trials and dosing regimens. The exposure-response model had high precision and limited bias for predicting body weight loss at 1 year in independent datasets, with increased precision when data from later time points were included in the prediction.. An exposure-response model has been established that quantitatively describes the relationship between systemic semaglutide exposure and weight loss and predicts weight-loss trajectories for people with overweight or obesity who are receiving semaglutide doses up to 2.4 mg once weekly.

Approved by the Food and Drug Administration (FDA) in 2017 for diabetes and in 2021 for weight loss, semaglutide has seen widespread use among individuals who aim to lose weight. The aim of this study was to evaluate weight loss and the influence of clinical factors on semaglutide patients in real-world clinical practice.. Using data from 10 health systems within the Greater Plains Collaborative (a PCORnet Clinical Research Network), nearly 4000 clinical factors encompassing demographic, diagnosis, and prescription information were extracted for semaglutide patients. A gradient-boosting, machine-learning classifier was developed for weight-loss prediction and identification of the most impactful factors via SHapley Additive exPlanations (SHAP) value extrapolation.. A total of 3555 eligible patients (539 of whom were observed 52 weeks following exposure) from March 2017 to April 2022 were studied. On average, individuals lost 4.44% (male individuals, 3.66%; female individuals, 5.08%) of their initial weight. History of diabetes mellitus diagnosis was associated with less weight loss, whereas prediabetes and linaclotide use were associated with more pronounced weight loss.. Weight loss in patients prescribed semaglutide from real-world evidence was strong but attenuated compared with previous clinical trials. Machine-learning analysis of electronic health record data identified factors that warrant further research and consideration when tailoring weight-loss therapy.

The weight loss following Semaglutide treatment, a GLP-1 receptor agonist, might be responsible for some effects observed on the nonalcoholic fatty liver disease of obese mice.. Two groups of C57BL/6 male mice (n = 30/group) were fed the diets Control (C) or high-fat (HF) for 16 weeks. Then, separated into six new groups for an additional four weeks (n = 10/group) and treated with Semaglutide (S, 40 µg/kg) or paired feeding (PF) with S groups (C; C-S; C-PF; HF; HF-S; HF-PF).. Semaglutide reduced energy consumption leading to weight loss. Simultaneously it improved glucose intolerance, glycated hemoglobin, insulin resistance/sensitivity, plasma lipids, and gastric inhibitory polypeptide. Semaglutide and paired feeding mitigated liver steatosis and adipose differentiation-related protein (Plin2) expression. Semaglutide also improved hormones and adipokines, reduced lipogenesis and inflammation, and increased beta-oxidation. Semaglutide lessened liver glucose uptake and endoplasmic reticulum (ER) stress. Among the 14 genes analyzed, 13 were modified by Semaglutide (93 %, six genes were changed exclusively by Semaglutide, and seven other genes were affected by the combination of Semaglutide and paired feeding). In seven genes, the paired diet showed no effect (50% of the genes tested). No marker was affected exclusively by paired feeding.. Semaglutide and the consequent weight loss reduced obese mice liver inflammation, insulin resistance, and ER stress. However, weight loss alone did show few or no action on some significant study findings, like liver steatosis, leptin, insulin, resistin, and amylin. Furthermore, hepatic inflammation mediated by MCP-1 and partially by TNF-alpha and IL6 were also not reduced by weight loss. Furthermore, weight loss alone did not lessen hepatic lipogenesis as determined by the findings of SREBP-1c, CHREBP, PPAR-alpha, and SIRT1. Semaglutide was implicated in improving glucose uptake and lessening ER stress by reducing GADD45, independent of weight loss.

To evaluate HbA1c and body weight changes when semaglutide 0.5- or 1.0-mg once-weekly (QW) is switched to dulaglutide 3.0- or 4.5-mg QW via exposure-response modelling.. HbA1c and body weight time-course models were developed and validated with data from the SUSTAIN 1 to 10 trials for semaglutide and the AWARD-11 trial for dulaglutide. Simulations were conducted for HbA1c and body weight over 52 weeks. In the initial 26 weeks, semaglutide was initiated at 0.25-mg and titrated to 0.5- or 1.0-mg QW via 4-weekly stepwise titration, followed by 26 weeks of dulaglutide initiated at 0.75- or 1.5-mg QW and escalated to 3.0- or 4.5-mg QW via 4-weekly stepwise titration.. At 26 weeks, model-predicted mean changes from baseline in HbA1c and weight for semaglutide 0.5 mg were up to -1.55% and -3.44 kg, respectively. After switching to dulaglutide 3.0 mg, further reductions were 0.19% and 1.40 kg, respectively, at 52 weeks. Predicted mean HbA1c and weight changes for semaglutide 1.0 mg at 26 weeks were -1.84% and -4.96 kg, respectively; after switching to dulaglutide 4.5 mg, HbA1c was maintained with additional weight reduction of up to 0.57 kg at 52 weeks. Glycaemic control was preserved when switching from semaglutide 1.0 mg to dulaglutide 3.0 mg.. Switching from semaglutide 0.5 mg to dulaglutide 3.0 or 4.5 mg with dose escalation potentially yields additional HbA1c and weight reductions; switching from semaglutide 1.0 mg to dulaglutide 4.5 mg may enhance weight loss.

To evaluate whether the potent hypophagic and weight-suppressive effects of growth differentiation factor-15 (GDF15) and semaglutide combined would be a more efficacious antiobesity treatment than either treatment alone by examining whether the neural and behavioural mechanisms contributing to their anorectic effects were common or disparate.. Three mechanisms were investigated to determine how GDF15 and semaglutide induce anorexia: the potentiation of the intake suppression by gastrointestinal satiation signals; the reduction in motivation to feed; and the induction of visceral malaise. We then compared the effects of short-term, combined GDF15 and semaglutide treatment on weight loss to the individual treatments. Rat pharmaco-behavioural experiments assessed whether GDF15 or semaglutide added to the satiating effects of orally gavaged food and exogenous cholecystokinin (CCK). A progressive ratio operant paradigm was used to examine whether GDF15 or semaglutide reduced feeding motivation. Pica behaviour (ie, kaolin intake) and conditioned affective food aversion testing were used to evaluate visceral malaise. Additionally, fibre photometry studies were conducted in agouti-related protein (AgRP)-Cre mice to examine whether GDF15 or semaglutide, alone or in combination with CCK, modulate calcium signalling in hypothalamic AgRP neurons.. Semaglutide reduced food intake by amplifying the feeding-inhibitory effect of CCK or ingested food, inhibited the activity of AgRP neurons when combined with CCK, reduced feeding motivation and induced malaise. GDF15 induced visceral malaise but, strikingly, did not affect feeding motivation, the satiating effect of ingested food or CCK signal processing. Combined GDF15 and semaglutide treatment produced greater food intake and body weight suppression than did either treatment alone, without enhancing malaise.. GDF15 and semaglutide reduce food intake and body weight through largely distinct processes that produce greater weight loss and feeding suppression when combined.

The ABCD semaglutide audit was designed to capture the routine clinical outcomes of people commenced on semaglutide in the UK. Previous work showed differential reductions in HbA1c and weight dependent on previous glucagon-like peptide-1 receptor agonist (GLP-1RA) exposure. The analysis, in this research letter, shows that decreases in HbA1c and weight associated with semaglutide occur irrespective of previous GLP-1RA use. However, HbA1c reductions were less if switched from dulaglutide or liraglutide and weight changes were attenuated if switched from dulaglutide or exenatide, potentially suggesting differing potencies between GLP-1RAs. Dedicated studies with head-to-head comparisons are needed to confirm these findings.

Prader-Willi syndrome is the most frequent genetic cause of obesity and is often complicated by glucose metabolism alterations. Conventional therapies prescribed for type 2 diabetes frequently failed to achieve adequate glycemic control in patients with Prader-Willi syndrome. Beneficial effects of glucagon like peptide-1 receptor agonists exenatide and liraglutide have been reported for the management of type 2 diabetes in Prader-Willi syndrome, but no data are currently available in this population on the use of semaglutide.. We report for the first time the use of semaglutide 1 mg per week in a 33-yearold man with Prader-Will syndrome complicated by poorly controlled diabetes and severe obesity. After 12 months of semaglutide treatment, we observed an important reduction in glycated hemoglobin levels (11.1% to 7.2%) and body weight (99.5 kg to 94.3 kg), with a notable decrease in fat mass and insulin requirements. Interestingly, our patient had already tried liraglutide therapy in adjunction to metformin and insulin therapy, reporting no substantial efficacy.. The beneficial effects of semaglutide on glycemic control and weight reduction provide a promising treatment for diabetes and obesity in Prader-Willi syndrome, even where other glucagons like peptide-1 receptor agonists have failed. Further studies are required to confirm the efficacy and safety of semaglutide in patients with Prader-Willi syndrome.

To assess cardiovascular, glycaemic, weight and safety outcomes of long-term treatment with dulaglutide 1.5 mg compared with placebo in patients with a baseline HbA1c of less than 7% versus 7% or higher.. Intention-to-treat analyses were performed on REWIND participants with a baseline HbA1c measurement, using Cox proportional hazards regression and mixed model for repeated measures. Subgroup analyses with factors for baseline HbA1c categories and their interaction with treatment group, as well as analyses within the HbA1c subgroups, were conducted. Additionally, sensitivity analyses were performed for baseline HbA1c subgroups of 6.5% or less and more than 6.5%.. Of the 9876 eligible participants, 3921 and 5955 had a baseline HbA1c of less than 7% and 7% or higher, respectively. Mean baseline HbA1c was 6.3% and 8.0% and the mean duration of diabetes was 9.0 and 11.6 years in the respective subgroups. The less than 7% subgroup was slightly older and less frequently insulin-treated. There was no evidence of a differential dulaglutide treatment effect on body mass index (BMI) reduction, cardiovascular or safety outcomes of interest between the baseline HbA1c subgroups. Treatment-by-baseline HbA1c group interaction was significant for HbA1c change from baseline (P < .001), with a greater reduction in the subgroup with higher baseline HbA1c values. Sensitivity analyses by baseline HbA1c subgroups of 6.5% or less and more than 6.5% showed similar results.. The reduced incidence of cardiovascular events, and the reduction in BMI in participants treated with once-weekly dulaglutide, were independent of the baseline HbA1c level. Conversely, participants with a higher baseline HbA1c level had greater reductions in HbA1c. Dulaglutide has a positive benefit-risk profile and can be considered in patients with comparatively well-controlled HbA1c levels seeking optimal metabolic control and cardiovascular benefits.

About 20-25% of patients experience weight regain (WR) or insufficient weight loss (IWL) after bariatric metabolic surgery (BS). Therefore, we aimed to retrospectively assess the effectiveness of adjunct treatment with the GLP-1 receptor agonist semaglutide in non-diabetic patients with WR or IWL after BS.. Post-bariatric patients without type 2 diabetes (T2D) with WR or IWL (n = 44) were included in the analysis. The primary endpoint was weight loss 3 and 6 months after initiation of adjunct treatment. Secondary endpoints included change in BMI, HbA1c, lipid profile, hs-CRP, and liver enzymes.. Patients started semaglutide 64.7 ± 47.6 months (mean ± SD) after BS. At initiation of semaglutide, WR after post-bariatric weight nadir was 12.3 ± 14.4% (mean ± SD). Total weight loss during semaglutide treatment was - 6.0 ± 4.3% (mean ± SD, p < 0.001) after 3 months (3.2 months, IQR 3.0-3.5, n = 38) and - 10.3 ± 5.5% (mean ± SD, p < 0.001) after 6 months (5.8 months, IQR 5.8-6.4, n = 20). At 3 months, categorical weight loss was > 5% in 61% of patients, > 10% in 16% of patients, and > 15% in 2% of patients. Triglycerides (OR = 0.99; p < 0.05), ALT (OR = 0.87; p = 0.05), and AST (OR = 0.89; p < 0.05) at baseline were negatively associated with weight loss of at least 5% at 3 months' follow-up (p < 0.05).. Treatment options to manage post-bariatric excess weight (regain) are scarce. Our results imply a clear benefit of adjunct treatment with semaglutide in post-bariatric patients. However, these results need to be confirmed in a prospective randomized controlled trial to close the gap between lifestyle intervention and revision surgery in patients with IWL or WR after BS.

Anti-obesity medications used with lifestyle intervention produce greater and more sustained weight loss than does lifestyle intervention alone. However, until 2021, FDA-approved medications for the long-term treatment of obesity in the general adult population had not demonstrated the sustained loss of 15% body weight needed to meet or exceed all guideline-recommended targets for weight-related complications. To meet this need, investigators launched the Semaglutide Treatment Effect in People with obesity (STEP) program of phase 3 clinical trials to assess the safety and efficacy of a weekly 2.4-mg subcutaneous injection of semaglutide, a glucagon-like peptide-1 receptor agonist (GLP-1RA). Following the results of STEPs 1 to 4, the FDA approved semaglutide therapy in patients with obesity. This article examines the design, efficacy, and safety of semaglutide therapy as revealed by the results of STEPs 1 to 4. These trials included adults with obesity who reported at least 1 unsuccessful attempt to reduce body weight by means of diet. STEP 2 studied effects on patients who also had type 2 diabetes (T2D); STEPs 1, 3, and 4 excluded patients with this condition. STEP 3 examined the effect of this pharmacotherapy plus intensive behavioral therapy and a 2-step, intensively restricted dietary plan. STEP 4 assessed the effects of continuing semaglutide 2.4 mg vs switching to placebo after an initial treatment period. In the trials comparing the effects of semaglutide 2.4‑mg treatment with those of placebo across 68 weeks and in patients with no T2D (ie, STEPs 1 and 3), patients treated with semaglutide achieved a mean -14.9% to -16.0% weight change. This far exceeds the 4.0% to 10.9% weight loss seen with other approved antiobesity medications. In STEPs 2 and 4, the estimated treatment differences between the semaglutide 2.4-mg and placebo arms were -6.2% and -14.8%, respectively. Safety and tolerability of this treatment in STEPs 1 to 4 was consistent with those of other GLP-1RA-based therapies. Ultimately, the results of the first 4 STEP trials demonstrated that semaglutide 2.4 mg is a safe, well-tolerated, and highly effective treatment to promote weight loss, avoid weight regain, and mitigate the effects of the prevalent, chronic disease of obesity. In November 2022, based upon the results of STEPs 1 to 3 and other trials, the American Gastroenterological Association recommended that semaglutide 2.4 mg "be prioritized over other approved [anti-obesity medic

Weight loss therapy is becoming more and more important, and two classes of molecules, namely amylin receptor and GLP-1 receptor agonists, have shown promise in this regard. Interestingly, these molecules have several overlapping pharmacological effects, such as suppression of gastric emptying, reduction of glucagon secretion and weight loss in common; however, they also have distinct effects on prandial insulin secretion. Hence, a combination of these two mechanisms is of significant interest.. In this study, we investigated the add-on potential of the dual amylin and calcitonin receptor agonist (DACRA) KBP-089 in combination with the GLP-1 receptor agonist liraglutide as obesity treatment in high-fat diet (HFD) fed rats.. Increasing doses of KBP-089 and liraglutide alone and in combination were studied with respect to their effects on body weight, food intake and glucose metabolism during a 9-week intervention study conducted in HFD rats. Further, the gastric emptying rate during an oral glucose tolerance was assessed. Treatment with KBP-089 and liraglutide dose-dependently lowered body weight 15% (at 2.5 μg/kg/day) and 7% (at 400 μg/kg/day) in HFD rats, respectively, while the combination resulted in a 21% body weight reduction, which was mirrored by reduction in fat depot sizes. Gastric emptying and glucose metabolism were improved, primarily by KBP-089, although liraglutide led to a reduction in fasting plasma glucagon.. DACRAs complement GLP-1 on food intake, body weight, and glucose tolerance indicating the potential for an add-on therapy.

In randomized controlled trials (RCTs) on type 2 diabetes (T2D) patients, the glucagon-like peptide-1 (GLP-1) receptor agonist (GLP-RA) dulaglutide reduced HbA1c and body weight, but generalizability of such findings to real-world T2D patients is challenging.. We evaluated effectiveness of dulaglutide in routine clinical practice, especially in subgroups of patient that are underrepresented in RCTs.. Retrospective multicenter study.. Diabetes outpatient clinics.. All consecutive patients who initiated dulaglutide between 2015 and 2018.. Changes in HbA1c and body weight were assessed up to 30 months after baseline. Effectiveness was analyzed in patient subgroups according to: prior use of GLP-1RA, persistence on treatment and dose, age, sex, disease duration, renal function, obesity, cardiovascular disease, or concomitant use of insulin or sulphonylurea.. From a background population of 83,116 patients, 2084 initiated dulaglutide (15.3% switching from another GLP-1RA), 1307 of whom had at least 1 follow-up visit. Overall, dulaglutide reduced HbA1c by 1.0% and body weight by 2.9 kg at the end of observation. These effects were more pronounced in GLP-1RA-naïve patients and in those with shorter disease duration. Improvement in HbA1c was highly significant and consistent across all subgroups, including those aged ≥ 75 years, nonobese, or with chronic kidney disease. Body weight declined in all subgroups and significantly more with the 1.5-mg versus 0.75-mg dose.. In real-world T2D patients, effectiveness of dulaglutide on HbA1c and body weight reduction was highly consistent and significant even in subgroups of patients poorly represented in RCTs.

Aim of this retrospective multicenter observational study was to evaluate the efficacy and safety of the glucagon-like peptide-1 receptor agonist (GLP-1 RA) dulaglutide in a type-2 diabetic real-world population and to determine the factors predicting the response in terms of glycated haemoglobin (HbA1c) and other relevant clinical outcomes. Data for efficacy outcomes, adverse events and drug discontinuation were collected from records of patients with type-2 diabetes treated with once-a-week 1.5 mg of dulaglutide for 12 months in routine clinical practice. Initial analysis included 782 patients and 626 had complete follow-up at 6- and 12-months. There was a significant reduction of HbA1c at 6 months (-1 ± 0.8 %, p < 0.0001), which remained stable at 12-months follow-up (-1 ± 0.9 %, p < 0.0001). The percentage of subjects with HbA1c≤7.0 % increased significantly from 7.2 % at baseline to 52.7 % at 6 months to 55.8 % at 12 months. Predictors of the achievement of HbA1c≤7.0 % were low baseline HbA1c and short duration of diabetes. The reduction of HbA1c was associated with reductions of BMI, waist circumference, fasting plasma glucose and blood pressures. Neither sex nor age had significant effects on any clinical or laboratory outcome. The effects of dulaglutide on HbA1c, BMI and SBP tended to be greater in patients who shifted from dipeptidyl peptidase-IV inhibitors (-0.8 ± 0.8 %) than other GLP-1 RA, even if an improvement of HbA1c reduction (-0.5 %) was also seen in those shifting from other GLP-1 RA. This study confirms that addition of dulaglutide 1.5 mg once a week in real word settings has beneficial effects on both clinical and laboratory outcomes in patients with uncontrolled type-2 diabetes. Dulaglutide has a greater effect on HbA1c in patients with higher baseline values and helps achieve a target HbA1c≤7.0 %, more consistently in patients with lower baseline HbA1c and shorter diabetes duration.

Gastrointestinal (GI) adverse events (AEs) are the most common AEs with glucagon-like peptide-1 receptor agonists (GLP-1RAs). Weight loss (WL) is slightly greater in people who experience GI AEs than those who do not. A previous mediation analysis of the SUSTAIN 1-5 trials indicated minor contribution of nausea/vomiting to the greater WL with once-weekly semaglutide versus comparators. Semaglutide demonstrated superior glycated hemoglobin and body weight (BW) reductions versus other GLP-1RAs in SUSTAIN 3 (versus exenatide extended release 2.0 mg), SUSTAIN 7 (versus dulaglutide) and SUSTAIN 10 (liraglutide 1.2 mg). The objective of this analysis was to assess if significantly greater WL with semaglutide versus other GLP-1RAs is mediated by nausea/vomiting and other GI AEs (diarrhea, constipation, dyspepsia) during dose escalation (baseline to week 12, when GI AEs are generally most prevalent) and from baseline to end of treatment (EOT: week 56 (SUSTAIN 3), 40 (SUSTAIN 7) or 30 (SUSTAIN 10)).. Subjects within trials were subdivided into those who reported (yes/no) nausea/vomiting or any other GI AE. Change from baseline in BW was assessed within each trial and subgroup. A mediation analysis separated WL into direct or indirect (mediated by GI AEs) effects.. From baseline to week 12 or EOT, the nausea/vomiting-mediated difference in WL was, respectively: 0.05 or 0.09 kg of 3.78 kg at EOT (SUSTAIN 3); 0.06 or 0.03 kg of 2.26 kg at EOT (low-dose comparison) and 0.08 or 0.04 kg of 3.55 kg at EOT (high-dose comparison) (SUSTAIN 7) and 0.05 or 0.09 kg of 3.82 kg at EOT (SUSTAIN 10).. In SUSTAIN 3, 7 and 10, nausea/vomiting by week 12 (end of dose escalation) or throughout treatment contributed minimally (<0.1 kg) to the superior WL with semaglutide versus GLP-1RA comparators at EOT.

Oral semaglutide is the first orally administered glucagon-like peptide-1 receptor agonist for the treatment of type 2 diabetes, and has been evaluated in the PIONEER clinical trial program. These trials assessed the proportions of patients achieving single and composite endpoints, encompassing glycemic control [defined in terms of glycated hemoglobin (HbA1c)], weight loss, and hypoglycemia. The present study assessed the cost of control with oral semaglutide versus empagliflozin, sitagliptin, and liraglutide in the US.. Four endpoints were evaluated: (1) HbA1c ≤ 6.5%; (2) HbA1c < 7.0%; (3) ≥ 1.0%-point HbA1c reduction and weight loss ≥ 3.0%; and (4) HbA1c < 7.0% without hypoglycemia and without weight gain. The proportions of patients achieving each endpoint were sourced from the PIONEER 2, 3 and 4 trials. Treatment costs were accounted over an annual time-period in 2019 US dollars (USD), based on wholesale acquisition cost. Cost of control was calculated by dividing treatment costs by the proportion of patients achieving each target.. Oral semaglutide was consistently associated with the lowest cost of control for all four endpoints. For the targets of HbA1c ≤ 6.5% and HbA1c < 7.0%, oral semaglutide 14 mg was associated with lower cost of control than empagliflozin 25 mg, sitagliptin 100 mg and liraglutide 1.8 mg by USD 15,036, 14,697, and 6996, respectively, and USD 931, 346 and 4497, respectively. For the double composite endpoint, cost of control was lower with oral semaglutide 14 mg by USD 525, 32,277 and 13,011, respectively versus empagliflozin 25 mg, sitagliptin 100 mg and liraglutide 1.8 mg. For the triple composite endpoint, cost of control was lower with oral semaglutide 14 mg by USD 1255, 7510 and 5774, respectively.. Oral semaglutide was associated with lower cost of bringing patients with type 2 diabetes to four clinically-relevant treatment targets versus empagliflozin, sitagliptin, and liraglutide in the US..

We aimed to test the hypothesis that addition of glucagon-like peptide-1 receptor agonists (GLP-1RAs) to insulin in C-peptide-positive patients with type 1 diabetes (T1D) will result in a reduction in glycated haemoglobin (HbA1c) with reduced insulin requirements and a rise in C-peptide concentrations. We conducted a retrospective analysis of 11 normal-weight patients with T1D consecutively treated with a GLP-1RA in addition to insulin. Paired t tests were used to compare the changes in HbA1c, insulin doses, body weight, body mass index, and C-peptide concentrations prior to and 12 ± 1 weeks after GLP-1RA therapy. At the end of 12 ± 1 weeks of GLP-1RA therapy, HbA1c fell from 10.74 ± 0.96% (95 ± 10.5 mmol/mol) to 7.4 ± 0.58% (58 ± 6.3mmol/mol) (P < 0.01), body weight fell from 71 ± 2.0 to 69 ± 2 kg (P = 0.06), and total insulin dose was reduced by 64% from 33 ± 6 to 11 ± 5 units (P < 0.01). Five out of 10 patients did not require any insulin. C-peptide concentrations increased significantly from 0.43 ± 0.09 ng/ml (0.14 ± 0.02 nmol/L) to 1.42 ± 0.42ng/ml (0.47 ± 0.13 nmol/L) (P = 0.01). Addition of GLP-1RA therapy to insulin in normal-weight patients with T1D led to a reduction in HbA1c with reduced insulin requirements, a 3.5-fold increase in C-peptide concentrations and freedom from insulin therapy in 50% of patients who tolerated the GLP-1RA therapy over a period of 12 ± 1 weeks.

The SUSTAIN 3 and 7 clinical trials compared the efficacy and safety of once-weekly semaglutide relative to exenatide extended-release (ER) and dulaglutide, respectively, in the treatment of patients with type 2 diabetes (T2D). The trials included a series of clinically relevant single and composite endpoints focused on improving glycemic control and reducing body weight, while avoiding hypoglycemia. The present study combined SUSTAIN 3 and 7 outcomes with short-term treatment costs to evaluate the relative cost of control of once-weekly semaglutide versus exenatide ER and dulaglutide.. Proportions of patients reaching three endpoints were taken from SUSTAIN 3 and 7 for comparisons with exenatide ER and dulaglutide, respectively. The endpoints investigated were HbA1c < 7.0%, HbA1c < 7.0% without hypoglycemia or weight gain, and a ≥ 1.0% HbA1c reduction with ≥ 5.0% weight loss. Annual per patient treatment costs were based on US wholesale acquisition costs from July 2018. Relative cost of control was calculated by plotting the ratio of the treatment costs and the ratio of the proportions of patients reaching each endpoint on the cost-efficacy plane.. Once-weekly semaglutide 0.5 mg and 1.0 mg were most effective at bringing patients to each of the three endpoints across both SUSTAIN trials. The efficacy-to-cost ratios for once-weekly semaglutide 0.5 mg and 1.0 mg were also superior to all comparators when assessing both the single endpoint of HbA1c < 7.0% and the two composite endpoints including weight loss and hypoglycemia.. The present study showed that once-weekly semaglutide 0.5 mg and 1.0 mg offer superior cost of control versus exenatide ER and dulaglutide in terms of achieving single and composite endpoints, based on an analysis of retrieved dropout data. Once-weekly semaglutide 0.5 mg and 1.0 mg would therefore represent good value for money in the USA, particularly in the attainment of multi-model T2D treatment goals.. Novo Nordisk A/S.

The long-acting glucagon-like peptide-1 receptor agonist dulaglutide acts by stimulating insulin secretion and reducing glucagon levels in a glucose-dependent manner both in the fasting and postprandial states, resulting in reductions of both fasting glucose (FG) and postprandial glucose (PPG). In contrast, the main mechanism of action of basal insulin is to reduce elevated FG by inhibiting hepatic glucose production. The aim of the present post hoc analysis of the phase 3 AWARD-2 trial was to investigate whether specific baseline glycaemic patterns respond differentially to dulaglutide compared to insulin glargine (glargine). We categorized participants into four subgroups based on prespecified glucose thresholds and their baseline FG and daily 2-hour mean PPG: low FG/low PPG; low FG/high PPG; high FG/low PPG; and high FG/high PPG. Changes in glycaemic measures in response to treatment with dulaglutide or glargine were evaluated in each subgroup. At 52 weeks, significant reductions from baseline in glycated haemoglobin (HbA1c) were observed in all subgroups with dulaglutide 1.5 mg and with glargine (all P < .05), except in patients with low FG/low PPG who received glargine. Greater HbA1c reductions were observed with dulaglutide 1.5 mg compared to glargine in all subgroups (all P ≤ .05), except in the low FG/high PPG subgroup.

A retrospective cohort study was conducted in patients with type 2 diabetes in an electronic medical record database to compare real-world, 6-month glycated haemoglobin (HbA1c) and weight outcomes for exenatide once weekly with those for dulaglutide and albiglutide. The study included 2465 patients: exenatide once weekly, n = 2133; dulaglutide, n = 201; and albiglutide, n = 131. The overall mean (standard deviation [s.d.]) age was 60 (11) years and 54% were men; neither differed among the comparison groups. The mean (s.d.) baseline HbA1c was similar in the exenatide once-weekly (8.3 [1.7]%) and dulaglutide groups (8.5 [1.5]%; P = .165), but higher in the albiglutide group (8.7 [1.7]%; P < .001). The overall mean (s.d.) HbA1c change was -0.5 (1.5)% (P < .001) and this did not differ among the comparison groups in either adjusted or unadjusted analyses. The mean (s.d.) weight change was -1.4 (4.7) kg for exenatide once weekly and -1.6 (3.7) kg for albiglutide (P = .579), but was greater for dulaglutide, at -2.7 (5.7) kg (P = .001). Outcomes were similar in subsets of insulin-naive patients with baseline HbA1c ≥7.0% or ≥9.0%. All agents significantly reduced HbA1c at 6 months, with no significant differences among agents or according to baseline HbA1c in insulin-naive subgroups.

To evaluate dose levels for semaglutide, a glucagon-like peptide-1 analogue approved for the treatment of type 2 diabetes, by examining the effects of demographic factors on efficacy and safety in an exposure-response analysis.. We analysed data from 1552 adults from four randomized phase III trials of 30 to 56 weeks' duration, investigating once-weekly semaglutide doses 0.5 and 1.0 mg. Exposure-response relationships were investigated using graphical and model-based techniques to assess the two dose levels and subgroups with the highest and lowest exposure and response.. The population had the following demographic characteristics: baseline mean age between 53.2 and 58.4 years, glycated haemoglobin (HbA1c) between 64 and 67 mmol/mol (8.0% and 8.3%), body weight between 71.3 and 96.2 kg, and diabetes duration between 4.2 and 8.9 years. Exposure-response analysis showed a clear HbA1c and weight reduction across exposures after 30 weeks, irrespective of baseline values. The exposure-response for HbA1c was influenced by baseline HbA1c, and body weight exposure-response was influenced by sex, with limited impact of other factors. Analyses for relevant subgroups of baseline body weight, baseline HbA1c and sex indicated clinically relevant additional benefits with regard to HbA1c and weight with 1.0 vs 0.5 mg semaglutide. The proportion of participants reporting gastrointestinal (GI) side effects increased with increasing exposure, but was counteracted by tolerance development.. The analysis showed that all subgroups obtained a clinically relevant benefit with semaglutide 0.5 mg and an additional benefit with semaglutide 1.0 mg. The increase in GI side effects with higher exposure was mitigated by gradually increasing the dose.

Glucose-dependent insulinotropic polypeptide (GIP) receptor (GIPR) has been identified in multiple genome-wide association studies (GWAS) as a contributor to obesity, and GIPR knockout mice are protected against diet-induced obesity (DIO). On the basis of this genetic evidence, we developed anti-GIPR antagonistic antibodies as a potential therapeutic strategy for the treatment of obesity and observed that a mouse anti-murine GIPR antibody (muGIPR-Ab) protected against body weight gain, improved multiple metabolic parameters, and was associated with reduced food intake and resting respiratory exchange ratio (RER) in DIO mice. We replicated these results in obese nonhuman primates (NHPs) using an anti-human GIPR antibody (hGIPR-Ab) and found that weight loss was more pronounced than in mice. In addition, we observed enhanced weight loss in DIO mice and NHPs when anti-GIPR antibodies were codosed with glucagon-like peptide-1 receptor (GLP-1R) agonists. Mechanistic and crystallographic studies demonstrated that hGIPR-Ab displaced GIP and bound to GIPR using the same conserved hydrophobic residues as GIP. Further, using a conditional knockout mouse model, we excluded the role of GIPR in pancreatic β-cells in the regulation of body weight and response to GIPR antagonism. In conclusion, these data provide preclinical validation of a therapeutic approach to treat obesity with anti-GIPR antibodies.

Previous studies have indicated that the secretion of the intestinal satiety hormone glucagon-like peptide-1 (GLP-1) is attenuated in obese subjects.. To compare meal-induced response of GLP-1 and glucose-dependent insulinotropic polypeptide (GIP) in obese and lean male subjects, to investigate the effect of a major weight reduction in the obese subjects, and to look for an association between these hormones and ad libitum food intake.. Plasma concentrations of intestinal hormones and appetite sensations were measured prior to, and every 30 min for 180 min after, ingestion of a 2.5 MJ solid test meal. Gastric emptying was estimated scintigraphically. An ad libitum lunch was served 3 h after the test meal.. Nineteen non-diabetic obese (body mass index (BMI) 34.1--43.8 kg/m(2)) and 12 lean (BMI 20.4--24.7 kg/m(2)) males. All obese subjects were re-examined after a mean stabilised weight loss of 18.8 kg (95% CI 14.4--23.2).. Total area under the GLP-1 response curve (AUC(total, GLP-1)) was lower in obese before and after the weight loss compared to lean subjects (P<0.05), although weight loss improved the response from 80 to 88% of that of the lean subjects (P=0.003). The GIP response was similar in obese and lean subjects. However, after the weight loss both AUC(total, GIP) and AUC(incremental, GIP) were lowered (P<0.05). An inverse correlation was observed between AUC(incremental, GIP) and energy intake at the subsequent ad libitum meal in all groups. In lean subjects ad libitum energy intake was largely predicted by the insulin response to the preceding meal (r(2)=0.67, P=0.001).. Our study confirmed previous findings of a reduced postprandial GLP-1 response in severely obese subjects. Following weight reduction, GLP-1 response in the obese subjects apparently rose to a level between that of obese and lean subjects. The data suggests that postprandial insulin and GIP responses are key players in short-term appetite regulation.

Acute pancreatitis (AP) initiates a generalized inflammatory response that increases intestinal permeability and promotes bacterial translocation (BT). Impairment of the intestinal epithelial barrier is known to promote BT. Glucagon-like peptide 2 (GLP-2), a 33 residue peptide hormone, is a key regulator of the intestinal mucosa by stimulating epithelial growth. The purpose of this study was to determine whether GLP-2 decreases intestinal permeability and BT in AP.. To examine whether GLP-2 can decrease intestinal permeability and thereby decrease BT in acute necrotizing pancreatitis, 34 male Sprague-Dawley rats (200 to 300 g) were studied. AP was induced in group I and group II by pressure injection of 3% taurocholate and trypsin into the common biliopancreatic duct (1 mg/kg of body weight). The potent analog to GLP-2 called ALX-0600 was utilized. Group I rats received GLP-2 analog (0.1 mg/kg, SQ, BID) and group II rats received a similar volume of normal saline as a placebo postoperatively for 3 days. Group III and group IV received GLP-2 analog and placebo, respectively. At 72 hours postoperatively, blood was drawn for culture of gram-negative organisms. Specimens from mesenteric lymph nodes (MLN), pancreas and peritoneum were harvested for culture of gram-negative bacteria. Intestinal resistance as defined by Ohm's law was determined using a modified Ussing chamber to measure transepithelial current at a fixed voltage. A point scoring system for five histologic features that include intestinal edema, inflammatory cellular infiltration, fat necrosis, parenchymal necrosis, and hemorrhage was used to evaluate the severity of pancreatitis. Specimens from MLN, pancreas, jejunum, and ileum were taken for pathology.. All group I and group II rats had AP. The average transepithelial resistance in group I was 82.8 Omega/cm(2) compared with 55.9 Omega/cm(2) in group II (P <0.01). Gram-negative BT to MLN, pancreas, and peritoneum was 80%, 0%, and 0%, respectively in group I compared with 100%, 30%, and 20% translocation in group II.. GLP-2 treatment significantly decreases intestinal permeability in acute pancreatitis.
