Initially developed as medications for diabetes mellitus, GLP-1 agonists have gained much popularity in the treatment of obesity and weight loss. The present case describes a 69-year-old woman with a history of peptic ulcer and use of NSAIDs, who presented with abdominal pain and oral intolerance refractory to conventional management, for which an upper digestive endoscopy was performed, diagnosing severe gastroparesis. Asking more about the story, revealed surreptitious use of semaglutide. She continued with supportive therapy and the symptoms resolved spontaneously. The present case report aims to warn of the potential risks of the use of GLP-1 analogues in the context of endoscopy with sedation.

Objective: We conducted a randomized, double-blind, placebo-controlled phase 2 trial to evaluate the efficacy and safety of mazdutide, a once-weekly glucagon-like peptide 1 and glucagon receptor dual agonist, in Chinese patients with type 2 diabetes., Research Design and Methods: Adults with type 2 diabetes inadequately controlled with diet and exercise alone or with stable metformin (glycated hemoglobin A1c [HbA1c] 7.0-10.5% [53-91 mmol/mol]) were randomly assigned to receive 3 mg mazdutide (n = 51), 4.5 mg mazdutide (n = 49), 6 mg mazdutide (n = 49), 1.5 mg open-label dulaglutide (n = 50), or placebo (n = 51) subcutaneously for 20 weeks. The primary outcome was change in HbA1c from baseline to week 20., Results: Mean changes in HbA1c from baseline to week 20 ranged from -1.41% to -1.67% with mazdutide (-1.35% with dulaglutide and 0.03% with placebo; all P < 0.0001 vs. placebo). Mean percent changes in body weight from baseline to week 20 were dose dependent and up to -7.1% with mazdutide (-2.7% with dulaglutide and -1.4% with placebo). At week 20, participants receiving mazdutide were more likely to achieve HbA1c targets of <7.0% (53 mmol/mol) and ≤6.5% (48 mmol/mol) and body weight loss from baseline of ≥5% and ≥10% compared with placebo-treated participants. The most common adverse events with mazdutide included diarrhea (36%), decreased appetite (29%), nausea (23%), vomiting (14%), and hypoglycemia (10% [8% with placebo])., Conclusions: In Chinese patients with type 2 diabetes, mazdutide dosed up to 6 mg was generally safe and demonstrated clinically meaningful HbA1c and body weight reductions., (© 2023 by the American Diabetes Association.)

Background: As new antidiabetic drugs, tirzepatide (Tir) and semaglutide (Sem) are progressively applied in clinical practice. However, their efficacy and safety profiles have not been comprehensively assessed. Therefore, a Bayesian network meta-analysis was used to evaluate and compare the efficacy and safety of Tir and Sem in treating type 2 diabetes mellitus (T2DM)., Methods: PubMed, EMBASE, Web of Science, Cochrane Library and ClinicalTrials.gov were systematically searched from inception to April 3rd, 2023. Randomized clinical trials (RCTs) comparing the efficacy and safety of Tir and Sem with placebo or the other antidiabetic drugs in treating T2DM were included. The efficacy outcomes included changes in glycated hemoglobin (HbA1c), body weight (BW), body mass index (BMI), and the proportion of participants with HbA1c< 7 %. The safety outcome was the proportion of participants experiencing gastrointestinal adverse events (GIAEs)., Results: A total of 38 studies involving 34,166 participants were included. Compared to 1 mg of subcutaneous Sem (Sem SC), 5 mg, 10 mg and 15 mg of Tir demonstrated superior efficacy in reducing HbA1c (mean difference (MD), [95 % CI], -0.22 [-0.40, -0.03] %, -0.42 [-0.60, -0.24] % and -0.53 [-0.71, -0.35] %, respectively) and BW (MD [95 % CI], -1.48 [-2.53, -0.43] kg, -4.00 [-5.05, -2.95] kg and -5.71 [-6.73, -4.68] kg, respectively). Conversely, 7 mg and 14 mg of oral Sem (Sem PO) displayed inferior efficacy in reducing HbA1c (MD [95 % CI], 0.47 [0.26, 0.68] % and 0.35 [0.16, 0.54] %, respectively) and BW (MD [95 % CI], 2.36 [1.24, 3.48] kg and 1.11 [0.10, 2.13] kg). However, 20 mg and 40 mg of Sem PO were non-inferior in reducing HbA1c (MD [95 % CI], 0.13 [-0.29, 0.55] % and 0.01 [-0.38, 0.40] %, respectively) and BW (MD [95 % CI], -0.41 [-2.71, 1.90] kg and -1.32 [-3.58, 0.92] kg). In terms of safety, compared to 1 mg of Sem SC, 5 mg, 10 mg and 15 mg of Tir did not significantly increase the incidence of GIAEs (odd ratio (OR) [95 % CI], 0.70 [0.42, 1.10], 0.87 [0.52, 1.36] and 0.99 [0.60, 1.54], respectively), while 7 mg of Sem PO showed a lower incidence of GIAEs (OR [95 % CI], 0.48 [0.25, 0.83]). Compared to insulin, 0.5 mg of Sem SC, 1 mg of Sem SC, 5 mg of Tir, 10 mg of Tir and 15 mg of Tir displayed better efficacy in lowering HbA1c (MD [95 % CI], -0.40 [-0.63, -0.18] %, -0.69 [-0.90, -0.48] %, -0.91 [-1.10, -0.72] %, -1.11 [-1.30, -0.92] % and -1.22 [-1.41, -1.03] %, respectively) and BW (MD [95 % CI], -5.34[-6.60, -4.09] kg, -6.70 [-7.90,-5.51] kg, -8.18 [-9.27, -7.10] kg, -10.70 [-11.79, -9.61] kg and -12.41 [-13.49,-11.33] kg, respectively). According to the surface under the cumulative ranking curve (SUCRA) value, among all the included interventions, 15 mg of Tir exhibited the most potent effect in reducing HbA1c (99.81 %) and BW (99.98 %), followed by 10 mg of Tir (96.83 % and 95.72 %), 5 mg of Tir (92.88 % and 86.04 %), 1 mg of Sem SC (85.85 % and 74.97 %), 40 mg of Sem PO (83.66 % and 84.31 %), 20 mg of Sem PO (76.98 % and 77.12 %), 300 mg of Can (49.93 % and 60.89 %), insulin (36.38 % and 0.22 %) and 100 mg of Sit (12.28 % and 18.51 %) respectively. Meanwhile, 5 mg, 10 mg, and 15 mg of Tir (48.32 %, 30.96 %, and 21.07 %, respectively), 0.5 mg and 1 mg of Sem SC (33.54 % and 24.77 %, respectively) significantly increased the incidence of GIAEs., Conclusion: Both Tir and Sem demonstrated favorable antidiabetic effects and were particularly suitable for T2DM patients who were obese or overweight. Despite a high incidence of GIAEs, their safety profile was deemed acceptable. Tir was the best option among all the included interventions., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 The Authors.

Aim: To evaluate glycaemic control, body weight, and safety outcomes following treatment with tirzepatide or dulaglutide in patients with type 2 diabetes (T2D) with a baseline haemoglobin (HbA1c) level of ≤8.5% (≤69 mmol/mol) versus >8.5% (>69 mmol/mol)., Materials and Methods: SURPASS J-mono was a 52-week, multicentre, randomized, double-blind, parallel, active-controlled, phase 3 study conducted in Japan. In this exploratory subgroup analysis of SURPASS J-mono, we examined mean change in HbA1c and body weight and the incidence of adverse events (AEs) in patients with a baseline HbA1c of ≤8.5% versus >8.5% after treatment with tirzepatide (5, 10 or 15 mg) or dulaglutide 0.75 mg., Results: Of 636 randomized participants, 203 had a baseline HbA1c of >8.5% and 433 had a baseline HbA1c of ≤8.5% (range ≥7.0% to ≤10.0%). Both subgroups showed significantly greater reductions in HbA1c and body weight with any-dose tirzepatide versus dulaglutide 0.75 mg, with greater HbA1c reductions observed in patients with a baseline HbA1c of >8.5% treated with tirzepatide (least squares mean [LSM] differences of -3.13% to -3.86%) or dulaglutide (LSM -1.81%) compared with patients with a baseline HbA1c of ≤8.5% (LSM -2.00% to -2.32%) or dulaglutide (LSM -1.05%; treatment-by-baseline HbA1c subgroup interaction P ≤ 0.001). For the tirzepatide treatment arms, LSM change from baseline in body weight ranged from -6.7 to -10.7 kg for the baseline HbA1c ≤8.5% subgroup and from -4.0 to -10.6 kg for the baseline HbA1c >8.5% subgroup, compared with -0.6 kg and -0.4 kg, respectively, for the dulaglutide arm. The incidence of hypoglycaemia was low, with no substantial difference in hypoglycaemia or treatment-emergent AEs between subgroups., Conclusions: Regardless of baseline HbA1c (≤8.5% or >8.5%), tirzepatide at doses of 5, 10 and 15 mg is effective in Japanese patients with T2D compared with dulaglutide 0.75 mg in terms of glycaemic control and body weight reduction, with an adequate safety profile consistent with previous reports., (© 2023 Eli Lilly Japan K.K and The Authors.

Aim: To compare the proportion of participants with type 2 diabetes (T2D) treated with once-weekly (OW) subcutaneous (SC) semaglutide versus comparators who achieved a composite metabolic endpoint., Materials and Methods: SUSTAIN 1-5, 7-10 and SUSTAIN China trial data were pooled. Participants with T2D (aged ≥18 years) and glycated haemoglobin ≥7.0% (≥53 mmol/mol) who had been randomized to OW SC semaglutide (0.5 or 1.0 mg) or comparator in addition to background medication. Using patient-level data pooled by treatment, proportions of participants achieving the metabolic composite endpoint, defined as glycated haemoglobin <7% (<53 mmol/mol), blood pressure <140/90 mmHg and non-high-density lipoprotein cholesterol <130 mg/dl (<3.37 mmol/L), were evaluated following baseline adjustments. Endpoints were analysed per trial using a binomial logistic regression model with treatment, region/country and stratification factor as fixed effects and baseline value as covariate. Pooled analysis used logistic regression with treatment and trial as fixed effects and baseline value as covariate., Results: This post hoc analysis included data from 7633 participants across 10 trials. The proportion of participants who achieved the metabolic composite endpoint was significantly higher with OW SC semaglutide 0.5 and 1.0 mg versus comparators (23.7% and 32.0% vs. 11.5%, respectively; p < .0001). Likewise, when the OW SC semaglutide doses were pooled, significantly higher proportions of patients receiving semaglutide achieved the composite metabolic endpoint versus comparators (29.1% vs. 11.4%, respectively; p < .0001)., Conclusions: Treatment with OW SC semaglutide versus comparators was associated with increased proportions of participants with T2D meeting the composite metabolic endpoint., (© 2023 The Authors.

Rationale: Obesity and diabetes of different types are considered global health risks with rising prevalence. In addition to low-calorie diet and daily exercise, several treatment options have been introduced to help patient in needs. Semaglutide (Ozempic) is one popular agent, which attracted the attention of both physicians and patients due to its positive outcome in improving glucose control and weight loss. However, no reports on the effect of semaglutide use on the oral cavity and specifically xerostomia are available in the literature. We are reporting 3 cases for patients who were using semaglutide and developed secondary xerostomia., Patient Concerns: Three female patients with median age of 34 (range 27-46) presented to the oral medicine clinic with chief complaint of xerostomia. All patients were overweight with a mean body mass index of 35.6 (range 35-37) and have been using semaglutide for weight loss for a mean duration of 11.3 weeks (range 6-16)., Diagnoses: All 3 patients had severe dryness in the mouth with minimal frothy saliva with mean modified Schirmer test of 9 mL at 3 minutes (range 8-10 mL). Following exclusion of other possible underlying medical problems, the diagnosis of semaglutide-induced hyposalivation was given to all patients., Interventions: The patients' management varied between discontinuation of the drug, the use of pilocarpine, and conservative symptomatic management., Outcomes: The patients resumed acceptable salivary flow., Lessons: We are reporting for the first time hyposalivation associated with the use of semaglutide. Further prospective, larger studies are warranted to confirm these findings., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2023 the Author(s).

Aim: To our knowledge, this is the first real-world study to investigate the safety and effectiveness of a glucagon-like peptide-1 receptor agonist in Chinese patients with type 2 diabetes mellitus (T2DM)., Materials and Methods: This prospective, observational, post-marketing study conducted at 46 hospitals in China included adults with T2DM prescribed dulaglutide in routine clinical practice. The primary endpoint was the incidence of treatment-emergent adverse events (TEAEs) and serious AEs in patients who received ≥1 dose of dulaglutide, for up to 24 weeks. Exploratory endpoints included changes in patient-reported glycated haemoglobin (HbA1c) and body weight. Post hoc analyses and multivariate regression were also performed., Results: From 20 January 2020 to 24 November 2021, 3291 patients received dulaglutide and entered the safety analysis. TEAEs were reported in 1333 (40.5%) patients; the most commonly reported were nausea (n = 193, 5.9%), diarrhoea (n = 183, 5.6%) and decreased appetite (n = 179, 5.4%). serious AEs were reported in 160 (4.9%) patients. TEAEs led to treatment discontinuation in 212 (6.4%) patients. The mean absolute change in HbA1c from baseline to week 24 was -1.65% (p < .001). Greater reductions in HbA1c at week 24 were observed in patients with T2DM duration ≤5 years (p = .002), baseline HbA1c ≥8.5% (p < .001), and without atherosclerotic cardiovascular disease (p = .002). The mean absolute change in body weight from baseline at week 24 was -2.62 kg (p < .001)., Conclusion: Dulaglutide showed a safety profile consistent with previous reports and significantly reduced HbA1c in a real-world setting. These findings support the clinical use of dulaglutide and inform the individualized treatment of patients with T2DM in China., (© 2023 The Authors.

Semaglutide (▼Ozempic solution for injection, ▼Rybelsus tablets-Novo Nordisk) was initially granted market authorisation for the treatment of type 2 diabetes as an adjunct to diet and exercise. In 2021 and 2022, regulatory agencies in the USA and Europe licensed semaglutide (▼Wegovy solution for injection-Novo Nordisk) for the treatment of individuals who are obese, or overweight and who have at least one weight-related comorbidity. Manufacturer-sponsored randomised controlled trials have shown a loss of almost 12% of body weight over a 68-week period, however, once the medication is stopped people regain most of their pretreatment weight. Gastrointestinal adverse events occur commonly with semaglutide, and pancreatitis, diabetic retinopathy and severe allergic reactions have also been reported. Extensive hype in social and general media has resulted in increased demand for semaglutide leading to supply problems across the various licensed products including those used for treatment of diabetes. In the UK, the National Institute for Health and Care Excellence has recommended semaglutide as an option for weight management for a maximum treatment duration of 2 years. Further studies are underway to assess the effect of semaglutide on longer-term health benefits., Competing Interests: Competing interests: None declared.

Aims: To determine the relationship between exposure and weight-loss trajectories for the glucagon-like peptide-1 analogue semaglutide for weight management., Materials and Methods: 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., Results: 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., Conclusion: 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., (© 2023 Novo Nordisk A/S.

Background: Heart failure with preserved ejection fraction is increasing in prevalence and is associated with a high symptom burden and functional impairment, especially in persons with obesity. No therapies have been approved to target obesity-related heart failure with preserved ejection fraction., Methods: We randomly assigned 529 patients who had heart failure with preserved ejection fraction and a body-mass index (the weight in kilograms divided by the square of the height in meters) of 30 or higher to receive once-weekly semaglutide (2.4 mg) or placebo for 52 weeks. The dual primary end points were the change from baseline in the Kansas City Cardiomyopathy Questionnaire clinical summary score (KCCQ-CSS; scores range from 0 to 100, with higher scores indicating fewer symptoms and physical limitations) and the change in body weight. Confirmatory secondary end points included the change in the 6-minute walk distance; a hierarchical composite end point that included death, heart failure events, and differences in the change in the KCCQ-CSS and 6-minute walk distance; and the change in the C-reactive protein (CRP) level., Results: The mean change in the KCCQ-CSS was 16.6 points with semaglutide and 8.7 points with placebo (estimated difference, 7.8 points; 95% confidence interval [CI], 4.8 to 10.9; P<0.001), and the mean percentage change in body weight was -13.3% with semaglutide and -2.6% with placebo (estimated difference, -10.7 percentage points; 95% CI, -11.9 to -9.4; P<0.001). The mean change in the 6-minute walk distance was 21.5 m with semaglutide and 1.2 m with placebo (estimated difference, 20.3 m; 95% CI, 8.6 to 32.1; P<0.001). In the analysis of the hierarchical composite end point, semaglutide produced more wins than placebo (win ratio, 1.72; 95% CI, 1.37 to 2.15; P<0.001). The mean percentage change in the CRP level was -43.5% with semaglutide and -7.3% with placebo (estimated treatment ratio, 0.61; 95% CI, 0.51 to 0.72; P<0.001). Serious adverse events were reported in 35 participants (13.3%) in the semaglutide group and 71 (26.7%) in the placebo group., Conclusions: In patients with heart failure with preserved ejection fraction and obesity, treatment with semaglutide (2.4 mg) led to larger reductions in symptoms and physical limitations, greater improvements in exercise function, and greater weight loss than placebo.

Aim: To compare the efficacy of tirzepatide 10 and 15 mg with semaglutide 2.4 mg using an indirect treatment comparison., Materials and Methods: 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., Results: 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)., Conclusions: 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., (© 2023 Eli Lilly & Company and The Authors.

Background: According to current consensus guidelines for type 2 diabetes management, bodyweight management is as important as attaining glycaemic targets. Retatrutide, a single peptide with agonist activity at the glucose-dependent insulinotropic polypeptide (GIP), GLP-1, and glucagon receptors, showed clinically meaningful glucose-lowering and bodyweight-lowering efficacy in a phase 1 study. We aimed to examine the efficacy and safety of retatrutide in people with type 2 diabetes across a range of doses., Methods: In this randomised, double-blind, double-dummy, placebo-controlled and active comparator-controlled, parallel-group, phase 2 trial, participants were recruited from 42 research and health-care centres in the USA. Adults aged 18-75 years with type 2 diabetes, glycated haemoglobin (HbA 1c ) of 7·0-10·5% (53·0-91·3 mmol/mol), and BMI of 25-50 kg/m 2 were eligible for enrolment. Eligible participants were treated with diet and exercise alone or with a stable dose of metformin (≥1000 mg once daily) for at least 3 months before the screening visit. Participants were randomly assigned (2:2:2:1:1:1:1:2) using an interactive web-response system, with stratification for baseline HbA 1c and BMI, to receive once-weekly injections of placebo, 1·5 mg dulaglutide, or retatrutide maintenance doses of 0·5 mg, 4 mg (starting dose 2 mg), 4 mg (no escalation), 8 mg (starting dose 2 mg), 8 mg (starting dose 4 mg), or 12 mg (starting dose 2 mg). Participants, study site personnel, and investigators were masked to treatment allocation until after study end. The primary endpoint was change in HbA 1c from baseline to 24 weeks, and secondary endpoints included change in HbA 1c and bodyweight at 36 weeks. Efficacy was analysed in all randomly assigned, except inadvertently enrolled, participants, and safety was assessed in all participants who received at least one dose of study treatment. The study is registered at ClinicalTrials.gov, NCT04867785., Findings: Between May 13, 2021, and June 13, 2022, 281 participants (mean age 56·2 years [SD 9·7], mean duration of diabetes 8·1 years [7·0], 156 [56%] female, and 235 [84%] White) were randomly assigned and included in the safety analysis (45 in the placebo group, 46 in the 1·5 mg dulaglutide group, and 47 in the retatrutide 0·5 mg group, 23 in the 4 mg escalation group, 24 in the 4 mg group, 26 in the 8 mg slow escalation group, 24 in the 8 mg fast escalation group, and 46 in the 12 mg escalation group). 275 participants were included in the efficacy analyses (one each in the retatrutide 0·5 mg group, 4 mg escalation group, and 8 mg slow escalation group, and three in the 12 mg escalation group were inadvertently enrolled). 237 (84%) participants completed the study and 222 (79%) completed study treatment. At 24 weeks, least-squares mean changes from baseline in HbA 1c with retatrutide were -0·43% (SE 0·20; -4·68 mmol/mol [2·15]) for the 0·5 mg group, -1·39% (0·14; -15·24 mmol/mol [1·56]) for the 4 mg escalation group, -1·30% (0·22; -14·20 mmol/mol [2·44]) for the 4 mg group, -1·99% (0·15; -21·78 mmol/mol [1·60]) for the 8 mg slow escalation group, -1·88% (0·21; -20·52 mmol/mol [2·34]) for the 8 mg fast escalation group, and -2·02% (0·11; -22·07 mmol/mol [1·21]) for the 12 mg escalation group, versus -0·01% (0·21; -0·12 mmol/mol [2·27]) for the placebo group and -1·41% (0·12; -15·40 mmol/mol [1·29]) for the 1·5 mg dulaglutide group. HbA 1c reductions with retatrutide were significantly greater (p<0·0001) than placebo in all but the 0·5 mg group and greater than 1·5 mg dulaglutide in the 8 mg slow escalation group (p=0·0019) and 12 mg escalation group (p=0·0002). Findings were consistent at 36 weeks. Bodyweight decreased dose dependently with retatrutide at 36 weeks by 3·19% (SE 0·61) for the 0·5 mg group, 7·92% (1·28) for the 4 mg escalation group, 10·37% (1·56) for the 4 mg group, 16·81% (1·59) for the 8 mg slow escalation group, 16·34% (1·65) for the 8 mg fast escalation group, and 16·94% (1·30) for the 12 mg escalation group, versus 3·00% (0·86) with placebo and 2·02% (0·72) with 1·5 mg dulaglutide. For retatrutide doses of 4 mg and greater, decreases in weight were significantly greater than with placebo (p=0·0017 for the 4 mg escalation group and p<0·0001 for others) and 1·5 mg dulaglutide (all p<0·0001). Mild-to-moderate gastrointestinal adverse events, including nausea, diarrhoea, vomiting, and constipation, were reported in 67 (35%) of 190 participants in the retatrutide groups (from six [13%] of 47 in the 0·5 mg group to 12 [50%] of 24 in the 8 mg fast escalation group), six (13%) of 45 participants in the placebo group, and 16 (35%) of 46 participants in the 1·5 mg dulaglutide group. There were no reports of severe hypoglycaemia and no deaths during the study., Interpretation: In people with type 2 diabetes, retatrutide showed clinically meaningful improvements in glycaemic control and robust reductions in bodyweight, with a safety profile consistent with GLP-1 receptor agonists and GIP and GLP-1 receptor agonists.

Aim: To assess health utility values in the Semaglutide Treatment Effect in People with obesity (STEP) 1-4 trials., Materials and Methods: The STEP 1-4 phase 3a, 68-week, double-blind randomized controlled trials assessed the efficacy and safety of semaglutide 2.4 mg versus placebo in individuals with a body mass index (BMI) of 30 kg/m 2 or higher or a BMI of 27 kg/m 2 or higher and at least one comorbidity (STEP 1, 3 and 4), or a BMI of 27 kg/m 2 or higher and type 2 diabetes (STEP 2). Patients received lifestyle intervention plus intensive behavioural therapy in STEP 3. Health-related quality of life was assessed using the Short Form 36-item Health Survey version 2 (SF-36v2) at baseline and week 68. Scores were converted into Short Form Six-Dimension version 2 (SF-6Dv2) utility scores or mapped onto the European Quality of Life Five-Dimension Three-Level (EQ-5D-3L) utility index using UK health utility weights., Results: At week 68, semaglutide 2.4 mg was associated with minor health utility score improvements from baseline (all trials), while scores for placebo typically decreased. SF-6Dv2 treatment differences by week 68 for semaglutide 2.4 mg versus placebo were significant in STEP 1 and 4 (P ≤ .001), but not STEP 2 or 3. EQ-5D-3L treatment differences by week 68 for semaglutide 2.4 mg versus placebo were significant in STEP 1, 2 and 4 (P < .001 for all), but not STEP 3., Conclusions: Semaglutide 2.4 mg was associated with improvement in health utility scores compared with placebo, reaching statistical significance in STEP 1, 2 and 4., (© 2023 The Authors.

Aim: To evaluate the efficacy and safety of once-weekly (QW) efpeglenatide in people with type 2 diabetes (T2D) suboptimally controlled with oral glucose-lowering drugs and/or basal insulin (BI)., Materials and Methods: Three phase 3, multicentre, randomized controlled trials compared the efficacy and safety of QW efpeglenatide versus dulaglutide when added to metformin (AMPLITUDE-D), efpeglenatide versus placebo when added to BI ± oral glucose-lowering drugs (AMPLITUDE-L) or metformin ± sulphonylurea (AMPLITUDE-S). All trials were terminated early by the sponsor because of funding rather than safety or efficacy concerns., Results: In AMPLITUDE-D, non-inferiority of efpeglenatide to dulaglutide 1.5 mg was shown in HbA1c reduction from baseline to week 56, least squares mean treatment difference (95% CI): 4 mg, -0.03% (-0.20%, 0.14%)/-0.35 mmol/mol (-2.20, 1.49); 6 mg, -0.08% (-0.25%, 0.09%)/-0.90 mmol/mol (-2.76, 0.96). The reductions in body weight (approximately 3 kg) from baseline to week 56 were similar across all treatment groups. In AMPLITUDE-L and AMPLITUDE-S, numerically greater reduction in HbA1c and body weight were observed at all doses of efpeglenatide than placebo. American Diabetes Association level 2 hypoglycaemia (< 54 mg/dL [< 3.0 mmol/L]) was reported in few participants across all treatment groups (AMPLITUDE-D, ≤ 1%; AMPLITUDE-L, ≤ 10%; and AMPLITUDE-S, ≤ 4%). The adverse events profile was consistent with other glucagon-like peptide-1 receptor agonists (GLP-1 RAs); gastrointestinal adverse events were most frequent in all three studies., Conclusions: In people with T2D suboptimally controlled with oral glucose-lowering drugs and/or BI, QW efpeglenatide was non-inferior to dulaglutide in terms of HbA1c reduction and showed numerically greater improvements than placebo in glycaemic control and body weight, with safety consistent with the GLP-1 RA class., (© 2023 John Wiley & Sons Ltd.)

Aims: Real-world data are required to support glucagon-like peptide-1 receptor agonist use in type 2 diabetes (T2D). SURE France assessed once-weekly semaglutide in adults with T2D in real-world clinical practice., Materials and Methods: This multicentre, prospective, open-label, single-arm study included adults with T2D and ≥1 documented glycated haemoglobin (HbA1c) value ≤12 weeks before semaglutide initiation. The primary endpoint was HbA1c change from baseline to end of study (EOS; ~30 weeks). Secondary endpoints included change from baseline to EOS in body weight (BW) and waist circumference (WC); and proportion achieving HbA1c targets. Baseline characteristics and safety were reported for the full analysis set (patients initiating semaglutide). Analysis of other endpoints was based on the effectiveness analysis set (study completers receiving semaglutide at EOS)., Results: Of 497 patients initiating semaglutide (41.6% female, mean age 58.3 years), 348 completed the study on treatment. Baseline HbA1c, diabetes duration, BW and WC, were 8.3%, 10.0 years, 98.2 kg and 114.2 cm, respectively. The most common reasons for initiating semaglutide were to improve glycaemic control (79.7%), reduce BW (69.8%) and address cardiovascular risk (24.1%). At EOS, mean changes were: HbA1c, -1.2% points [95% confidence interval (CI) -1.32; -1.10]; BW, -4.7 kg (95% CI -5.38; -4.07); and WC, -4.9 cm (95% CI -5.94; -3.88). At EOS, 81.7%, 67.7% and 51.6% of patients achieved an HbA1c target of <8.0%, <7.5% and <7.0%, respectively. No new safety concerns were identified., Conclusions: These results support the benefits of semaglutide in a real-world setting in adults with T2D in France showing a significant reduction in HbA1c and body weight., (© 2023 The Authors.

Aim: To describe the design of the SOUL trial (Semaglutide cardiOvascular oUtcomes triaL) and the baseline clinical data of its participants., Materials and Methods: In SOUL, the effects of oral semaglutide, the first oral glucagon-like peptide-1 receptor agonist, on the risk of cardiovascular (CV) events in individuals with type 2 diabetes and established atherosclerotic CV disease (ASCVD) and/or chronic kidney disease (CKD) will be assessed. SOUL is a randomized, double-blind, parallel-group, placebo-controlled CV outcomes trial comparing oral semaglutide (14 mg once daily) with placebo, both in addition to standard of care, in individuals aged ≥50 years with type 2 diabetes and evidence of ASCVD (coronary artery disease [CAD], cerebrovascular disease, symptomatic peripheral arterial disease [PAD]) and/or CKD (estimated glomerular filtration rate <60 mL/min/1.73 m 2 ). The primary outcome is time from randomization to first occurrence of a major adverse CV event (MACE; a composite of CV death, nonfatal myocardial infarction or nonfatal stroke). This event-driven trial will continue until 1225 first adjudication-confirmed MACEs have occurred. Enrolment has been completed., Results: Overall, 9650 participants were enrolled between June 17, 2019 and March 24, 2021 (men 71.1%, White ethnicity 68.9%, mean age 66.1 years, diabetes duration 15.4 years, body mass index 31.1 kg/m 2 , glycated haemoglobin 63.5 mmol/mol [8.0%]). The most frequently used antihyperglycaemic medications at baseline were metformin (75.7%), insulin and insulin analogues (50.5%), sulphonylureas (29.1%), sodium-glucose cotransporter-2 inhibitors (26.7%) and dipeptidyl peptidase-4 inhibitors (23.0%). At randomization, 70.7% of participants had CAD, 42.3% had CKD, 21.1% had cerebrovascular disease and 15.7% had symptomatic PAD (categories not mutually exclusive). Prevalent heart failure was reported in 23.0% of participants., Conclusion: SOUL will provide evidence regarding the CV effects of oral semaglutide in individuals with type 2 diabetes and established ASCVD and/or CKD., (© 2023 The Authors.

Introduction: Obesity treatment is evolving rapidly with the emergence of agents targeting incretin receptors. Retatrutide, a triple agonist of these receptors, shows promise in obesity management., Areas Covered: Retatrutide, in phase-2 trials, exhibited significant reductions in glycated hemoglobin (HbA1c) and dose-dependent weight loss in individuals with type 2 diabetes mellitus (T2DM). In non-T2DM individuals, it produced substantial weight loss and improved glucose levels, albeit with gastrointestinal side effects. The role of glucagon receptor agonism in the management of heart failure and its potential impact on eating patterns have also been covered in this article., Expert Opinion: Although the reductions in HbA1c and dose-dependent weight loss among individuals with T2DM were significantly more for higher doses of retatrutide, it needs to be observed that the active comparator was dulaglutide, which is not approved for the treatment of obesity, at a dose of 1.5 mg, which is much lower than the highest approved dose of 4.5 mg. Dose-dependent increase in heart rate and incidents of mild to moderate cardiac arrythmias raise cardiovascular safety concerns and signify that carrying out long-term cardiovascular outcome trials (CVOTs) will be critical. In addition, retatrutide's potential in heart failure management is intriguing given the series of positive findings of semaglutide on cardiovascular outcomes.

Aims: 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., Materials and Methods: 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., Results: 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., Conclusions: 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., (© 2023 The Authors.

Aim: To investigate the effects of switching from liraglutide or dulaglutide to once-weekly semaglutide on glycaemic control and treatment satisfaction in patients with type 2 diabetes., Materials and Methods: In this multicentre, open-labelled, prospective, randomized, parallel-group comparison study, patients treated with liraglutide 0.9-1.8 mg/day (plan A) or dulaglutide 0.75 mg/week (plan B) were either switched to semaglutide or continued current therapy. The primary endpoint was the mean change in glycated haemoglobin over 24 weeks. The secondary endpoints included the changes of Diabetes Treatment Satisfaction Questionnaire scores, body weight and metabolic indices., Results: In total, 110 patients were enrolled, and 10 were excluded; therefore, 37 patients in plan A and 63 patients in plan B completed the study. Glycated haemoglobin levels were significantly reduced in the semaglutide group in both plans [plan A, 7.8% ± 1.0% to 7.8% ± 0.7% (liraglutide) vs. 7.9% ± 0.7% to 7.3% ± 0.7% (semaglutide), p < .01; plan B, 7.8% ± 1.0% to 7.9% ± 1.2% (dulaglutide) vs. 7.8% ± 0.8% to 7.1% ± 0.6% (semaglutide), p < .01]. Semaglutide also improved Diabetes Treatment Satisfaction Questionnaire scores in both groups (plan A, +0.1 vs. +8.3, p < .01; plan B, -1.2 vs. +3.5, p < .01). Switching from dulaglutide yielded greater reductions in body weight and improved metabolic parameters., Conclusions: Once-weekly semaglutide administration improved glycaemic control and treatment satisfaction after switching from liraglutide or dulaglutide. These results highlighted a useful treatment option for patients with metabolic abnormalities despite glucagon-like receptor-1 receptor agonist treatment., (© 2023 John Wiley & Sons Ltd.)

Aim: To investigate the impact of treatment with once-weekly subcutaneous semaglutide, a glucagon-like peptide-1 receptor agonist (GLP-1RA), for up to 2 years in people with type 2 diabetes (T2D) managed in routine clinical practice., Materials and Methods: The study was based on data from national registries. People who redeemed at least one prescription of semaglutide and had 2 years of follow-up were included. Data were collected at baseline and after 180, 360, 540 and 720 days of treatment (all timepoints ± 90 days)., Results: In total, 9284 people redeemed at least one semaglutide prescription (intention-to-treat) and 4132 people redeemed semaglutide continuously (on-treatment). For the on-treatment cohort, the median (interquartile range) age was 62.0 (16.0) years, diabetes duration was 10.8 (8.7) years, and glycated haemoglobin (HbA1c) level was 62.0 (18.0) mmol/mol at baseline. A subset of the on-treatment cohort, comprising 2676 people, had HbA1c measurements at baseline and at least once during 720 days. The mean (95% confidence interval) changes in HbA1c after 720 days were -12.6 (-13.6; -11.6) mmol/mol (P < 0.001) for GLP-1RA-naïve people, and -5.6 (-6.2; -5.0) mmol/mol (P < 0.001) for GLP-1RA-experienced people. Similarly, 55% of GLP-1RA-naïve people and 43% of GLP-1RA-experienced people reached a HbA1c target of ≤53 mmol/mol after 2 years., Conclusions: People treated with semaglutide in routine clinical practice experienced clinically relevant and sustained improvements in glycaemic control after 180, 360, 540 and 720 days, irrespective of former GLP-1RA exposure, effects which were comparable with those observed in clinical studies. These results support the use of semaglutide in routine clinical practice for the long-term management of T2D., (© 2023 The Authors.

Aim: Glucagon-like peptide-1 receptor agonists improve glycaemic control: some are now available as oral and subcutaneous formulations, and some have indications for reducing cardiovascular risk. The expanded scope for these therapies warrants comprehensive safety evaluations. We report the safety/tolerability of subcutaneous and oral semaglutide from the SUSTAIN and PIONEER clinical trial programmes, respectively., Materials and Methods: Adverse events (AEs) from 16 randomized placebo- or active-controlled phase IIIa trials in patients with type 2 diabetes (n = 11 159) including once-weekly subcutaneous semaglutide (n = 3150; SUSTAIN trials) or once-daily oral semaglutide (n = 4116; PIONEER trials) were analysed. Data pools were analysed for each programme, with separate analyses of cardiovascular outcomes trials (CVOTs; n = 6480)., Results: In the phase IIIa pools, gastrointestinal disorders were reported in 41.9%/39.1% of patients with subcutaneous/oral semaglutide, respectively (most prevalent during initiation/escalation) versus 22.0%/24.8% with comparators. Rates of kidney disorders, acute pancreatitis, malignant neoplasms, hypoglycaemia, diabetic retinopathy, heart failure and other cardiovascular events were similar for semaglutide versus comparators. Cholelithiasis incidence was higher with subcutaneous and oral semaglutide versus placebo. Diabetic retinopathy incidence was higher with subcutaneous semaglutide versus placebo in SUSTAIN 6. Small pulse rate increases occurred with both formulations; there was no increased rate of arrhythmias. Fatal AE incidence was similar between semaglutide and comparators. Versus placebo, CVOTs showed a reduced risk of major adverse cardiovascular events with subcutaneous semaglutide and non-inferiority criteria were met with oral semaglutide., Conclusions: The most common AEs with semaglutide were gastrointestinal disorders, which decreased with continued therapy. These comprehensive safety/tolerability data may better inform patient selection and guidance in care., (© 2023 The Authors. Diabetes, Obesity and Metabolism published by John Wiley & Sons Ltd.)

Objective: The glucagon-like peptide-1 receptor agonist dulaglutide reduced MACE in the Researching Cardiovascular Events with a Weekly Incretin in Diabetes (REWIND) trial. This article expores the relationship of selected biomarkers to both dulaglutide and major adverse cardiovascular events (MACE)., Research Design and Methods: In this post hoc analysis, stored fasting baseline and 2-year plasma samples from 824 REWIND participants with MACE during follow-up and 845 matched non-MACE participants were analyzed for 2-year changes in 19 protein biomarkers. Two-year changes in 135 metabolites were also analyzed in 600 participants with MACE during follow-up and in 601 matched non-MACE participants. Linear and logistic regression models were used to identify proteins that were associated with both dulaglutide treatment and MACE. Similar models were used to identify metabolites that were associated with both dulaglutide treatment and MACE., Results: Compared with placebo, dulaglutide was associated with a greater reduction or lesser 2-year rise from baseline in N-terminal prohormone of brain natriuretic peptide (NT-proBNP), growth differentiation factor 15 (GDF-15), high-sensitivity C-reactive protein, and a greater 2-year rise in C-peptide. Compared with placebo, dulaglutide was also associated with a greater fall from baseline in 2-hydroxybutyric acid and a greater rise in threonine (P < 0.001). Increases from baseline in two of the proteins (but neither metabolite) were associated with MACE, including NT-proBNP (OR 1.267; 95% CI 1.119, 1.435; P < 0.001) and GDF-15 (OR 1.937; 95% CI 1.424, 2.634; P < 0.001)., Conclusions: Dulaglutide was associated with a reduced 2-year rise from baseline of NT-proBNP and GDF-15. Higher rises of these biomarkers were also associated with MACE., (© 2023 by the American Diabetes Association.)

Background: The purpose of this case report is to describe a case of vitreous hemorrhage in a patient with a history of diabetic retinopathy and receiving dulaglutide for the management of type 2 diabetes mellitus (T2DM)., Case Summary: A 64-year-old African American male with a past medical history of T2DM and severe diabetic retinopathy for 4 years was restarted on dulaglutide 1.5 mg weekly after being off therapy for 3 months. Baseline laboratory test results included hemoglobin A1c (HbA1c) of 8.8% and random blood glucose (BG) of 280 mg/dL. In addition, the patient had an average fasting BG of 150 mg/dL. In absence of intolerance, the dulaglutide dose was gradually maximized to 4.5 mg weekly and HbA1c decreased to 7.3% and random BG to 121 mg/dL at week 12 since reinitiation. At week 17 of therapy, the patient presented to the emergency department with a 1-day history of vision loss in the left eye and was diagnosed as having vitreous hemorrhage. The etiology for vitreous hemorrhage is unclear and may be a spontaneous episode. In discussion with the patient and the ophthalmologist, dulaglutide was restarted at 1.5 mg once weekly. After 4 weeks of reinitiation, the patient denied any recurrent symptoms of vitreous hemorrhage or worsening diabetic retinopathy. The most recent ophthalmology evaluation indicated no change in diabetic retinopathy., Practice Implications: This case report adds to the limited body of evidence available for the incidence of vitreous hemorrhage in the setting of glucagon-like peptide-1 receptor agonists (GLP-1 RAs) therapy and pre-existing diabetic retinopathy. The case report illustrates that a history of diabetic retinopathy should not automatically preclude the use of GLP-1 RAs., (Copyright © 2023 American Pharmacists Association®.

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., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Background: Patients with type 2 diabetes (T2D) treated with glucagon-like peptide-1 receptor agonists may experience reductions in weight and blood pressure. The primary objective of the current study was to determine the weight-dependent and weight-independent effects of ~ 6 months treatment with dulaglutide 1.5 mg treatment in participants with T2D., Methods: Mediation analysis was conducted for five randomized, placebo-controlled trials of dulaglutide 1.5 mg to estimate the weight-dependent (i.e., mediated by weight) and weight-independent effects from dulaglutide vs. placebo on change from baseline for systolic blood pressure (SBP), diastolic blood pressure (DBP), and pulse pressure. A random-effects meta-analysis combined these results. To investigate a dose response between dulaglutide 4.5 mg and placebo, mediation analysis was first conducted in AWARD-11 to estimate the weight-dependent and weight-independent effects of dulaglutide 4.5 mg vs. 1.5 mg, followed by an indirect comparison with the mediation result for dulaglutide 1.5 mg vs. placebo., Results: Baseline characteristics were largely similar across the trials. In the mediation meta-analysis of placebo-controlled trials, the total treatment effect of dulaglutide 1.5 mg after placebo-adjustment on SBP was - 2.6 mmHg (95% CI - 3.8, - 1.5; p < 0.001) and was attributed to both a weight-dependent effect (- 0.9 mmHg; 95% CI: - 1.4, - 0.5; p < 0.001) and a weight-independent effect (- 1.5 mmHg; 95% CI: - 2.6, - 0.3; p = 0.01), accounting for 36% and 64% of the total effect, respectively. For pulse pressure, the total treatment effect of dulaglutide (- 2.5 mmHg; 95% CI: - 3.5, - 1.5; p < 0.001) was 14% weight-dependent and 86% weight-independent. For DBP there was limited impact of dulaglutide treatment, with only a small weight-mediated effect. Dulaglutide 4.5 mg demonstrated an effect on reduction in SBP and pulse pressure beyond that of dulaglutide 1.5 mg which was primarily weight mediated., Conclusions: Dulaglutide 1.5 mg reduced SBP and pulse pressure in people with T2D across the placebo-controlled trials in the AWARD program. While up to one third of the effect of dulaglutide 1.5 mg on SBP and pulse pressure was due to weight reduction, the majority was independent of weight. A greater understanding of the pleotropic effects of GLP-1 RA that contribute to reduction in blood pressure could support developing future approaches for treating hypertension.

Introduction: SURE Netherlands (NCT03929679) evaluated the use of once-weekly (OW) semaglutide, a glucagon-like peptide 1 receptor agonist (GLP-1RA), in routine clinical care for individuals with type 2 diabetes (T2D)., Methods: Adults (age ≥ 18 years) with T2D were enrolled into the single-arm study. The primary endpoint was change from baseline to end of study (EOS;  approx. 30 weeks) in glycated haemoglobin (HbA 1c ). Secondary endpoints were change from baseline to EOS in body weight (BW) and waist circumference (WC). Proportions of participants achieving predefined HbA 1c targets and weight-loss responses at EOS, safety, health-related quality of life (HRQoL) and treatment satisfaction were assessed., Results: In total, 211 participants (mean age 60.5 years; diabetes duration 13.3 years) initiated semaglutide; most were receiving metformin (82.9%) and/or basal insulin (59.2%) at baseline, and 6.2% switched from another GLP-1RA. Mean baseline HbA 1c , BW and WC were 8.6%, 105.2 kg and 118.8 cm. In the 186 (88.2%) participants receiving semaglutide at EOS, mean reduction in HbA 1c with semaglutide was - 1.2%-points (95% [confidence interval] CI - 1.3; - 1.0; p < 0.0001), with 124 (70.5%), 95 (54.0%) and 65 (36.9%) participants achieving HbA 1c targets of < 8.0%, < 7.5% and < 7.0%, respectively. Mean reduction in BW was - 7.8 kg [95% CI - 8.7; - 6.8; p < 0.0001], corresponding to relative reduction of - 7.5% [95% CI - 8.4; - 6.6; p < 0.0001]. Improvements in WC (- 8.8 cm [95% CI - 10.4; - 7.2; p < 0.0001]), HRQoL and treatment satisfaction were observed, including across most Short-Form 36 Health Survey domains. One serious adverse drug reaction (cholecystitis) was reported. Eight participants (all receiving concomitant insulin) experienced severe or documented hypoglycaemia., Conclusion: Individuals with T2D treated with OW semaglutide experienced significant and clinically relevant improvements in glycaemic control and BW from baseline. These results from a diverse real-world population in the Netherlands support the use of OW semaglutide in treating adults with T2D in routine clinical practice., (© 2022. The Author(s).)

What is this summary about? This is a plain language summary of the STEP TEENS research study, which was originally published in the New England Journal of Medicine . As more teenagers are living with obesity than ever before, researchers are searching for new treatments. This was the first study looking at how well the medicine semaglutide works as a treatment for obesity in teenagers. What were the results? In this study, researchers looked at the effect of semaglutide on body mass index (BMI) and weight loss compared to a dummy medicine (placebo). A 17% decrease in BMI was reported for teenagers treated with semaglutide compared with placebo. For weight loss, an 18 kg decrease was seen when comparing semaglutide with placebo. Researchers found that there were more teenagers who had weight loss of 5%, 10%, 15%, and 20% or more in the group given semaglutide compared with the group given placebo. Improvements were also seen with semaglutide treatment for some risk factors for other diseases caused by obesity. Semaglutide was generally well tolerated by the teenagers with obesity in this study, and serious medication side effects did not happen very often. What do the results mean? The results from this study showed that there were no safety issues with semaglutide in teenagers with obesity, and that semaglutide can be used to help them lose weight.

Background: Semaglutide is a Glucagon-like peptide-1 receptor agonist used in the second-line treatment of poorly controlled type 2 diabetes and can be used in monotherapy or associated with other oral antidiabetics or even insulin, increasing the effectiveness of the treatment. This work aims to analyze the profile of adverse drug reactions reported for semaglutide in Eudravigilance., Research Design and Methods: Data on Individual Cases Safety Reports were obtained from the database of the centralized European spontaneous reporting system Eudravigilance by accessing www.adrreports.eu. (1 December 2021)., Results: It is possible to observe a high prevalence of gastrointestinal disorders (N = 3502, 53.2%). The most severe reported cases were primarily gastrointestinal disorders, metabolic, and nutritional disorders, eye disorders, renal and urinary disorders and cardiac disorders, with an evident higher prevalence of adverse gastrointestinal events both in oral and injectable dosage form (N = 133, 50.0% vs N = 588, 47.2%, respectively). Through a comparative analysis, semaglutide had a greater number of reported gastrointestinal adverse events compared to sitagliptin and empaglifozin (p < 0.00001)., Conclusions: Semaglutide has a good safety profile, however the definition of subgroups within the type 2 diabetes population who are particularly prone to develop serious adverse event when treated with GLP-1 RAs is crucial.

Aims/introduction: The etiology and treatment of type 2 diabetes might differ between specific populations. This post-hoc exploratory analysis assessed the efficacy and safety of once-weekly subcutaneous semaglutide vs comparators in Japanese individuals with type 2 diabetes in comparison with the total population from four phase III studies in the Trial to Evaluate Cardiovascular and Other Long-term Outcomes with Semaglutide in Subjects with Type 2 Diabetes (SUSTAIN) program., Materials and Methods: This analysis was carried out with data from the SUSTAIN 1, 2, 5 and 9 trials. Post-hoc analyses were carried out to assess outcomes in all participants and in Japanese participants in each study. The primary end-point was the change from baseline to end of study in glycated hemoglobin (%). The confirmatory secondary end-point was change from baseline to end of study in bodyweight (kg)., Results: Change from baseline to end of study in glycated hemoglobin with once-weekly semaglutide ranged from -1.32 to -1.85% points in the overall populations, and -1.69 to -2.49% points in Japanese participants. With once-weekly semaglutide, relative bodyweight was reduced from baseline to end of study by 4.0-7.3% in the overall populations, and 2.7-10.4% in Japanese participants. In the Japanese subpopulation, no new safety concerns were identified with once-weekly semaglutide, and there were no adverse events leading to death or severe hypoglycemic episodes., Conclusions: In this post-hoc analysis, participants with type 2 diabetes initiating once-weekly semaglutide experienced improvements in glycated hemoglobin and bodyweight in both the overall and Japanese population, and no new safety concerns were identified among Japanese participants, supporting the efficacy of once-weekly semaglutide in this population., (© 2022 The Authors.

Background: Nonalcoholic fatty liver disease (NAFLD) is commonly observed in patients with type 2 diabetes (T2D). Semaglutide, a glucagon-like peptide 1 receptor agonist, may have a therapeutic role by targeting common mechanisms involved in the pathophysiology of T2D and NAFLD. The study aimed to assess the effectiveness of Semaglutide on NAFLD in patients with T2D., Methods: Forty-eight patients were treated with subcutaneous Semaglutide in add-on to metformin for 52 weeks. After the baseline visit (T0), follow-up was scheduled quarterly (T3, and T6) and then at 12 months of therapy (T12). During each visit, body composition was analyzed by phase-sensitive bio-impedance, and NAFLD was diagnosed and staged by Ultrasound (US) imaging. Surrogate biomarkers of NAFLD were also calculated and followed over time., Results: A significant decrease in anthropometric and glucometabolic parameters, insulin resistance, liver enzymes, and laboratory indices of hepatic steatosis was observed during treatment. Similarly, fat mass and visceral adipose tissue (VAT) decreased over time more than skeletal muscle and free-fat mass. US-assessed VAT thickness and the 12-point steatosis score also declined at T3 up to T12. Liver steatosis improved in most patients (70%), showing a reduction by at least one class in the semiquantitative US staging., Conclusion: Besides glucose control and body composition improvements, Semaglutide was effective in ameliorating the clinical appearance and severity of NAFLD in T2D patients.

To assess the efficacy and safety of dulaglutide in the treatment of Asian type 2 diabetes mellitus (T2DM), along with first-line hypoglycemic drugs. Systematic review and meta-analysis. Cochrane Library, Pubmed, Embase, and www.clinicaltrials.gov databases were searched from inception to September 27, 2022. The studies evaluating adults (≥ 18 years) undergoing dulaglutide (0.75 mg and 1.5 mg) and first-line hypoglycemic drugs were considered. There were only English languages. We used Stata 12.0 software to detect the risk of bias. 4 randomized controlled trials (RCTs), and 1 observational study. Both dulaglutide 0.75 mg dose group and 1.5 mg dose group could significantly reduce HbA1c [Dulaglutide 0.75 mg: WMD = - 0.20, 95% CI (- 0.28, - 0.11), P < 0.0001; Dulaglutide 1.5 mg: WMD = - 0.49, 95% CI (- 0.67, - 0.30), P < 0.0001] in Asian T2DM patients. In reducing fasting blood glucose (FBG) level, there was no significant difference observed in 2 dose groups. The body weight of patients in both dulaglutide dose groups was significantly reduced. In safety, the incidence of adverse events in the dulaglutide 0.75 mg dose group was slightly higher than that in the first-line drug group, but there was no statistically significant difference in the incidence of adverse events between the 1.5 mg dose group and the first-line drug group. Furthermore, the incidences of hypoglycemic events in both groups were higher than that in the first-line drug group. Two doses of dulaglutide showed better efficacy for Asian T2DM patients, but patients should be vigilant about the occurrence of hypoglycemia and gastrointestinal discomfort. However, more number and better quality of RCTs are suggested to confirm long-term safety and efficacy., (© 2022. The Author(s).)

Glucagon-like peptide-1 (GLP-1) receptor agonists (GLP-1RAs) were first introduced for the treatment of type 2 diabetes (T2D) in 2005. Despite the high efficacy and other benefits of GLP-1RAs, their uptake was initially limited by the fact that they could only be administered by injection. Semaglutide is a human GLP-1 analog that has been shown to significantly improve glycemic control and reduce body weight, in addition to improving cardiovascular outcomes, in patients with T2D. First approved as a once-weekly subcutaneous injection, semaglutide was considered an ideal peptide candidate for oral delivery with a permeation enhancer on account of its low molecular weight, long half-life, and high potency. An oral formulation of semaglutide was therefore developed by co-formulating semaglutide with sodium N-(8-[2-hydroxybenzoyl]amino)caprylate, a well-characterized transcellular permeation enhancer, to produce the first orally administered GLP-1RA. Pharmacokinetic analysis showed that stable steady-state concentrations could be achieved with once-daily dosing owing to the long half-life of oral semaglutide. Upper gastrointestinal disease and renal and hepatic impairment did not affect the pharmacokinetic profile. In the phase III PIONEER clinical trial program, oral semaglutide was shown to reduce glycated hemoglobin and body weight compared with placebo and active comparators in patients with T2D, with no new safety signals reported. Cardiovascular efficacy and safety are currently being assessed in a dedicated outcomes trial. The development of an oral GLP-1RA represents a significant milestone in the management of T2D, providing an additional efficacious treatment option for patients., (© 2022. The Author(s).)

Aim: 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., Materials and Methods: 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%., Results: 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., Conclusions: 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., (© 2022 Eli Lilly and Company.

Aim: To conduct an adjusted indirect treatment comparison (aITC) of the efficacy of tirzepatide 5/10/15 mg versus semaglutide 2 mg in patients with type 2 diabetes., Materials and Methods: The primary analysis was a Bucher aITC of the change from baseline at week 40 in HbA1c (%) and body weight (kg). Aggregate data from the SURPASS-2 study that met the HbA1c inclusion criterion of the SUSTAIN FORTE study and from SUSTAIN FORTE metformin-only treated patients were used for primary analysis., Results: The SURPASS-2 refined population comprised 238/245/240 and 240 participants for tirzepatide 5/10/15 mg and semaglutide 1 mg, respectively. The SUSTAIN FORTE metformin-only population comprised 222 and 227 participants for semaglutide 1 and 2 mg, respectively. In this aITC, tirzepatide 10 and 15 mg significantly reduced HbA1c versus semaglutide 2 mg with an estimated treatment difference (ETD) of -0.36% (95% confidence interval [CI] -0.63, -0.09) and -0.4% (95% CI -0.67, -0.13), respectively. Tirzepatide 10 and 15 mg significantly reduced body weight versus semaglutide 2 mg with an ETD of -3.15 kg (95% CI -4.84, -1.46) and -5.15 kg (95% CI -6.85, -3.45), respectively. There were no significant differences between tirzepatide 5 mg and semaglutide 2 mg on change from baseline in HbA1c and body weight., Conclusions: In this aITC, HbA1c and weight reductions were significantly greater for tirzepatide 10 and 15 mg versus semaglutide 2 mg and were similar for tirzepatide 5 mg versus semaglutide 2 mg. These findings provide comparative effectiveness insights in the absence of a head-to-head clinical trial., (© 2022 Eli Lilly and Company.

Background: GLP-1 RA (glucagon-like peptide-1 receptor agonists), including semaglutide, may reduce stroke risk in people with type 2 diabetes. This post hoc analysis examined the subcutaneous and oral semaglutide effects, versus placebo, on stroke and its subtypes in people with type 2 diabetes at high cardiovascular risk., Methods: SUSTAIN 6 (Trial to Evaluate Cardiovascular and Other Long-Term Outcomes With Semaglutide in Subjects With Type 2 Diabetes) and PIONEER 6 (Peptide Innovation for Early Diabetes Treatment) were randomized cardiovascular outcome trials of subcutaneous and oral semaglutide in people with type 2 diabetes at high cardiovascular risk, respectively. Time to first stroke and stroke subtypes were analyzed using a Cox proportional hazards model stratified by trial with pooled treatment as a factor. The impact of prior stroke, prior myocardial infarction or stroke, age, sex, systolic blood pressure, estimated glomerular filtration rate, and prior atrial fibrillation on treatment effects was assessed using interaction P values. Risk of major adverse cardiovascular event was analyzed according to prior stroke., Results: A total of 106/6480 participants had a stroke (1.0 event/100 patient-years of observation [PYO]). Semaglutide reduced incidence of any stroke versus placebo (0.8 versus 1.1 events/100 PYO; hazard ratio, 0.68 [95% CI, 0.46-1.00]; P =0.048), driven by significant reductions in risk of small-vessel occlusion (0.3 versus 0.7 events/100 PYO; hazard ratio, 0.51 [95% CI, 0.29-0.89]; P =0.017). Hazard ratios for risk of any stroke with semaglutide versus placebo were 0.60 (95% CI, 0.37-0.99; 0.5 versus 0.9 events/100 PYO) and 0.89 (95% CI, 0.47-1.69; 2.7 versus 3.0 events/100 PYO) in those without and with prior stroke, respectively. Except for prior atrial fibrillation ( P interaction =0.025), no significant interactions were observed between treatment effects on risk of any stroke and subgroups investigated, or between treatment effects on risk of major adverse cardiovascular event and prior stroke ( P interaction >0.05 for all)., Conclusions: Semaglutide reduced incidence of any first stroke during the trials versus placebo in people with type 2 diabetes at high cardiovascular risk, primarily driven by small-vessel occlusion prevention. Semaglutide treatment, versus placebo, lowered the risk of stroke irrespective of prior stroke at baseline., Registration: URL: https://www., Clinicaltrials: gov; Unique identifier: NCT01720446 and NCT02692716.

Aims: This post hoc analysis investigated the effect of dulaglutide on cardiovascular disease (CVD) risk factors in subgroups of participants at increased CVD risk in the AWARD-11 study., Methods: Participants who received once weekly dulaglutide 1.5, 3.0 or 4.5 mg for 52 weeks were categorized according to their baseline Framingham CVD risk category [low (N = 295), medium (N = 481) and high (N = 1054) risk], as well as their baseline CVD risk according to the REWIND study eligibility criteria (N = 953). Serum lipids and vital signs were assessed at baseline and at 52 weeks. Data were analysed as least squares mean percentage change from baseline for lipids and least squares mean change from baseline for vital signs., Results: Demographic and baseline clinical characteristics were balanced across doses within the CVD risk groups. In the high Framingham CVD risk and REWIND-like groups, dulaglutide resulted in dose-related decreases in total cholesterol (≤6.0%), non-high-density lipoprotein cholesterol (≤8.8%), very-low-density lipoprotein cholesterol (≤19.4%) and triglycerides (≤21.5%), with little change in low-density lipoprotein cholesterol and high-density lipoprotein cholesterol. Systolic and diastolic blood pressure decreased up to 5.6 mmHg and 1.6 mmHg, respectively, and heart rate increased up to 2 beats/min., Conclusions: This post hoc analysis suggests the magnitude of the favourable effects of dulaglutide 3.0 mg and 4.5 mg on several cardiometabolic CVD risk factors was similar to, if not greater than, those of dulaglutide 1.5 mg among participants with type 2 diabetes and increased CVD risk., Clinicaltrials: gov Identifier: NCT03495102., (© 2022 Eli Lilly and Company.

Background: 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., Aim: This systematic review and meta-analysis quantified the efficacy of subcutaneous semaglutide in treating obesity in non-diabetic adult patients compared to placebo., Method: 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., Results: The initial search identified 332 relevant articles and ultimately retained four randomized controlled trials encompassing 2,882 participants with a BMI ≥ 27 kg/m 2 . Patients treated with semaglutide experienced a clinically significant reduction in mean body weight - 11.62 kg (95% CI: -13.03 to -10.21; P < 0.00001)., Conclusion: This systematic review and meta-analysis validates the clinical efficacy of semaglutide for the treatment of obesity in the adult, non-diabetic population., (© 2022.

Objective: To review the pharmacology, efficacy, and safety of high-dose once-weekly semaglutide for chronic weight management., Data Sources: PubMed/MEDLINE and ClinicalTrials.gov were searched (inception to September 8, 2021) using keywords "semaglutide" and "obesity," "weight," "high dose," "high-dose," or "2.4.", Study Selection and Data Extraction: Clinical trials with published results were included. Publications studying the oral or <2.4 mg formulation of semaglutide were excluded., Data Synthesis: Four phase 3, multicenter, randomized, double-blind trials demonstrated efficacy of high-dose once-weekly semaglutide compared with placebo for weight loss. Study populations included patients with overweight or obesity (STEP 1, STEP 3, and STEP 4) or patients with diabetes and with overweight or obesity (STEP 2). Lifestyle interventions for diet and exercise were included for all participants. Weight loss from baseline was significant for all studies, and secondary outcomes demonstrated cardiometabolic improvements including waist circumference, systolic blood pressure, and lipid profiles. Gastrointestinal adverse effects were common, but the medication was otherwise well tolerated., Relevance to Patient Care and Clinical Practice: High-dose semaglutide offers significant weight-lowering potential and favorable effects on cardiometabolic risk factors and glycemic indices. Clinicians and patients should consider the route and frequency of administration, adverse effect profile, and cost when choosing an antiobesity medication. The importance of concomitant lifestyle interventions should be emphasized., Conclusions: High-dose once-weekly semaglutide can significantly reduce weight, and although gastrointestinal adverse effects were common, it is generally well tolerated.
