Purpose: Dulaglutide is a long-acting glucagon-like peptide-1 receptor agonist that is not cleared by the kidneys and has proven efficacy and safety in patients with diabetic kidney disease. We aimed to evaluate the 1-year efficacy of dulaglutide in patients with diabetic kidney disease who have used the drug for more than 1 year., Methods: This retrospective, observational study comprised 131 patients with an estimated glomerular filtration rate (eGFR) of less than 60 mL/min/1.73 m 2 who had received dulaglutide for more than one year between June 2016 and May 2023. The primary outcome measures were changes in glycosylated hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), and body weight from baseline to the 12-month follow-up, with assessments performed at six-month intervals. Subgroup analyses were conducted based on age, sex, baseline body mass index, FPG, and HbA1c, and insulin administration at baseline and last follow-up., Findings: The mean age was 60.0 ± 10.2 years, and 61.1% of the participants were males. Baseline HbA1c, FPG, and body weight were 9.1% (76.0 mmol/mol), 186.8 mg/dL, and 79.3 kg, respectively. Dulaglutide significantly reduced HbA1c, FPG, and body weight from baseline to the 12-month follow-up (mean ± standard error: -1.2 ± 0.1%, -34.8 ± 6.9 mg/dL, and -2.3 ± 0.5 kg, respectively; P < 0.001). Subgroup analysis revealed significant differences in HbA1c reduction based on baseline HbA1c., Implications: Dulaglutide exhibited sustained glucose-lowering and weight-reduction effects during the initial 1 year of treatment in patients with diabetic kidney disease. Altogether, dulaglutide could serve as a favorable long-term therapeutic option for patients with diabetic kidney disease in real-world clinical settings., 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 © 2024 The Author(s).

Semaglutide is found to be efficient for weight loss in patients with overweight or obesity with diabetes mellitus (DM). With a wide range of adverse events reported, the efficacy and safety of once-weekly subcutaneous semaglutide in individuals without DM, with overweight or obesity, is unclear. We conducted a comprehensive meta-analysis of randomized studies on once-weekly semaglutide in this patient population. We identified nine studies with 11,641 patients in the semaglutide group and 10,479 in the placebo group. We observed that semaglutide resulted in significant benefits, including change in body weight (%): mean difference (MD) of -11.49% (p < 0.0001), change in absolute body weight: MD of -11.74 kg (p < 0.0001), and change in waist circumference: MD of -9.06 cm (p < 0.0001). Gastrointestinal side effects are predominant including nausea: odds ratio (OR) of 4.06 (p < 0.0001), vomiting: OR of 4.43 (p < 0.0001), diarrhea: OR of 2.10 (p < 0.0001), constipation: OR of 2.43 (p < 0.0001), gallbladder disorders: OR of 1.26 (p = 0.010), and cholelithiasis: OR of 2.06 (p = 0.04). Serious adverse events were not statistically significant: OR of 1.06 (p = 0.82). However, the percentage of participants discontinuing due to adverse events and gastrointestinal side effects was statistically significant: ORs of 2.22 (p < 0.0001) and 3.77 (p < 0.0001), respectively. This study shows that in patients with overweight or obesity without DM, once-weekly subcutaneous semaglutide can significantly decrease body weight without risk of serious adverse events when compared with a placebo. However, gastrointestinal side effects are predominant with semaglutide, which can result in medication discontinuation., (© 2024 The Author(s).

Introduction: Glucagon-like peptide 1 receptor agonists (GLP1Ras) have emerged as pivotal agents in diabetes management and organ protection. However, their use is limited due to the necessity for injectable administration. The advent of the first oral GLP1Ra (oral semaglutide) in Japan since 2021 is expected to expand its usage. The aim of this study is to survey the efficacy and tolerability of oral semaglutide in clinical practice., Materials and Methods: We retrospectively analyzed 120 outpatients diagnosed with type 2 diabetes mellitus who had received oral semaglutide for >6 months. Changes in clinical parameters during oral semaglutide treatment from baseline to 12 months were analyzed. The inverse probability weighting method using the propensity score was used to evaluate the differences in clinical parameters at 6 months after treatment, based on the patients' obesity levels., Results: Body weight (BW), glycated hemoglobin A 1c (HbA 1c ), and alanine aminotransferase (ALT) levels at baseline decreased significantly after treatment compared with those at 12 months (P < 0.001, P < 0.001, and P = 0.03, respectively). The patients were divided into two groups using a cutoff baseline body mass index (BMI) of 30.3 kg/m 2 . Although no significant difference was observed, changes in body weight and HbA 1c indicated a potentially greater decrease in the BMI ≧ 30.3 group than that in the BMI < 30.3 group (P = 0.07 and 0.13, respectively). Among 206 registered patients, 25 (12.1%) discontinued oral-semaglutide treatment owing to adverse effects, including gastrointestinal symptoms., Conclusions: Oral semaglutide treatment demonstrates efficacy and tolerability for managing type 2 diabetes mellitus in Japan. Significant improvements in metabolic factors induced by oral semaglutide are anticipated, particularly in obese patients., (© 2024 The Authors.

Introduction: Leukocytoclastic vasculitis (LCV) is a small vessel vasculitis involving arterioles, capillaries and postcapillary venules. LCV is generally confined to the skin, with extracutaneous manifestations occurring less frequently. LCV has multiple potential etiologies. Indeed, histological LCV can be found in anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis, immune complex vasculitis, vasculitis associated with systemic diseases (i.e. sarcoidosis, Sjögren's syndrome, rheumatoid arthritis, and systemic lupus erythematosus), or in vasculitis associated with cancer, infections, sepsis and use of certain medications. LCV can also be idiopathic in up to 50% of cases., Case Report: Semaglutide is a glucagon-like peptide 1 (GLP-1) receptor agonist used for management of type 2 diabetes mellitus (T2DM), obesity and overweight associated with one or more weight-related comorbidities. A case of drug-induced LCV has already been described with the use of once-daily oral semaglutide. Herein, we describe the first case of skin-limited LCV induced by once-weekly subcutaneous semaglutide in a 73-year-old man with T2DM, who experienced the complete resolution of the skin lesions shortly after the discontinuation of semaglutide therapy., Conclusion: Future prospective studies, adverse event reporting and post-marketing surveillance will certainly contribute to establishing if LCV represents a less rare than expected side effect of both oral and subcutaneous semaglutide formulations.

Introduction: The prevalence of obesity has increased worldwide over the past decades. Regional variations exist in the relationship between body mass index (BMI), body fat, and health risks: Asians typically have a lower BMI than people of European descent, but a higher risk of obesity-related comorbidities. However, there is a paucity of evidence for anti-obesity medications (AOMs) in East Asian populations. In this study, we aimed to systematically review evidence regarding the safety and efficacy of AOMs among adults with obesity disease in East Asia, and to assess the feasibility of conducting an indirect treatment comparison (ITC) between the semaglutide and mazindol trials., Methods: The Embase, MEDLINE, and ICHUSHI databases were searched via the Ovid SP platform for randomized controlled trials, in English or Japanese, reporting data on semaglutide or mazindol therapy with placebo or diet and exercise as comparators. The potential risks of bias in conducting a population-adjusted ITC were determined based on the heterogeneity of potential effect modifiers and variations in study design., Results: Of 21 publications, 2 were included in this study based on the eligibility criteria. The STEP 6 study established the clinical efficacy of subcutaneous semaglutide compared with placebo in the reduction of body weight and cardiometabolic risk factors [glycated hemoglobin (HbA 1c ), total cholesterol, and systolic blood pressure] among Japanese and South Korean people with obesity disease. Mazindol also proved beneficial in reducing body weight and total cholesterol compared with placebo in Japan. Both semaglutide and mazindol were associated with higher rates of adverse events and treatment discontinuation than placebo. An ITC between the two studies was not deemed feasible based on the potential risks of bias., Conclusions: Semaglutide and mazindol are associated with significant body weight reduction among people with obesity in East Asia. Further research based on label indications and up-to-date real-world data among East Asian people with obesity would help determine additional clinical benefits., (© 2024. The Author(s).)

Background: There are currently limited data regarding the effect of semaglutide 2·4 mg in individuals with obesity and prediabetes in clinical trials. We aimed to assess the efficacy and safety of semaglutide 2·4 mg for weight management and glycaemic control in participants with obesity and prediabetes., Methods: STEP 10 was a randomised, double-blind, parallel-group, phase 3 trial done across 30 trial sites in Canada, Denmark, Finland, Spain, and the UK and included participants aged 18 years or older with a BMI of 30 kg/m 2 or higher and prediabetes according to UK National Institute for Health and Care Excellence criteria (defined as having at least one of the following at screening: HbA 1c of 6·0-6·4% [42-47 mmol/mol] or fasting plasma glucose [FPG] of 5·5-6·9 mmol/L). Participants were randomly assigned (2:1) to once-weekly subcutaneous semaglutide 2·4 mg or placebo with diet and physical activity counselling for 52 weeks, followed by a 28-week off-treatment period. Primary endpoints were percentage change in bodyweight and proportion of participants reverting to normoglycaemia (HbA 1c <6·0% [<42 mmol/mol] and FPG <5·5 mmol/L) at week 52 (assessed in all randomly assigned participants by intention to treat). Selective safety data were collected for participants who received at least one dose of study drug. This trial is registered with ClinicalTrials.gov, NCT05040971, and is complete., Findings: Between Sept 16 and Dec 29, 2021, 138 participants were randomly assigned to semaglutide 2·4 mg and 69 to placebo. 147 (71%) were female and 60 (29%) were male; 183 (88%) were White. All randomly assigned participants received at least one dose of study drug. Baseline mean age was 53 years (SD 11), bodyweight 111·6 kg (22·2), BMI 40·1 kg/m 2 (6·9), waist circumference 120·1 cm (14·7), HbA 1c 5·9% (0·3; 41·3 mmol/mol [3·0]), and FPG 5·9 mmol/L (0·6). There was a significantly greater reduction in bodyweight with semaglutide 2·4 mg than with placebo at week 52 (-13·9% [SD 0·7] vs -2·7% [0·6]; estimated treatment difference -11·2% [95% CI -13·0 to -9·4]; p<0·0001). Greater proportions of participants reverted to normoglycaemia at week 52 with semaglutide 2·4 mg than with placebo (103 [81%] of 127 vs nine [14%] of 64; odds ratio 19·8 [95% CI 8·7 to 45·2]; p<0·0001). Serious adverse events occurred in 12 (9%) participants receiving semaglutide 2·4 mg versus six (9%) receiving placebo. Adverse events leading to treatment discontinuation occurred in eight (6%) participants in the semaglutide 2·4 mg group versus one (1%) participant in the placebo group. No new safety signals were reported., Interpretation: Semaglutide 2·4 mg provided superior reduction in bodyweight and reversion to normoglycaemia versus placebo in participants with obesity and prediabetes. The safety and tolerability profile was consistent with previous studies and with the GLP-1 receptor agonist class. These findings support the potential use of semaglutide 2·4 mg as a treatment option for individuals with obesity and prediabetes to achieve reversion to normoglycaemia., Funding: Novo Nordisk., Translation: For the Spanish translation of the abstract see Supplementary Materials section., Competing Interests: Declaration of interests AV, HAKM, and MQ are employees and shareholders of Novo Nordisk.

Importance: Although tirzepatide and semaglutide were shown to reduce weight in randomized clinical trials, data from head-to-head comparisons in populations with overweight or obesity are not yet available., Objective: To compare on-treatment weight loss and rates of gastrointestinal adverse events (AEs) among adults with overweight or obesity receiving tirzepatide or semaglutide labeled for type 2 diabetes (T2D) in a clinical setting., Design, Setting, and Participants: In this cohort study, adults with overweight or obesity receiving semaglutide or tirzepatide between May 2022 and September 2023 were identified using electronic health record (EHR) data linked to dispensing information from a collective of US health care systems. On-treatment weight outcomes through November 3, 2023, were assessed. Adults with overweight or obesity and regular care in the year before initiation, no prior glucagon-like peptide 1 receptor agonist receptor agonist use, a prescription within 60 days prior to initiation, and an available baseline weight were identified. The analysis was completed on April 3, 2024., Exposures: Tirzepatide or semaglutide in formulations labeled for T2D, on or off label., Main Outcomes and Measures: On-treatment weight change in a propensity score-matched population, assessed as hazard of achieving 5% or greater, 10% or greater, and 15% or greater weight loss, and percentage change in weight at 3, 6, and 12 months. Hazards of gastrointestinal AEs were compared., Results: Among 41 222 adults meeting the study criteria (semaglutide, 32 029; tirzepatide, 9193), 18 386 remained after propensity score matching. The mean (SD) age was 52.0 (12.9) years, 12 970 were female (70.5%), 14 182 were white (77.1%), 2171 Black (11.8%), 354 Asian (1.9%), 1679 were of other or unknown race, and 9563 (52.0%) had T2D. The mean (SD) baseline weight was 110 (25.8) kg. Follow-up was ended by discontinuation for 5140 patients (55.9%) receiving tirzepatide and 4823 (52.5%) receiving semaglutide. Patients receiving tirzepatide were significantly more likely to achieve weight loss (≥5%; hazard ratio [HR], 1.76, 95% CI, 1.68, 1.84; ≥10%; HR, 2.54; 95% CI, 2.37, 2.73; and ≥15%; HR, 3.24; 95% CI, 2.91, 3.61). On-treatment changes in weight were larger for patients receiving tirzepatide at 3 months (difference, -2.4%; 95% CI -2.5% to -2.2%), 6 months (difference, -4.3%; 95% CI, -4.7% to -4.0%), and 12 months (difference, -6.9%; 95% CI, -7.9% to -5.8%). Rates of gastrointestinal AEs were similar between groups., Conclusions and Relevance: In this population of adults with overweight or obesity, use of tirzepatide was associated with significantly greater weight loss than semaglutide. Future study is needed to understand differences in other important outcomes.

Background: Semaglutide is increasingly used in the management of type 2 diabetes mellitus and obesity. Ensuring the safety of this medication is crucial for its clinical use. This meta-analysis evaluates the safety profile of semaglutide across patient populations and treatment durations., Methods: Randomized controlled trials assessing the safety of semaglutide vs. placebo, with specified treatment durations were identified. The primary outcome was occurrence of any cardiovascular adverse events. Secondary outcomes included sudden cardiac death, adverse events leading to death, adverse events, gastrointestinal side effects, occurrence of hypoglycemia, and new-onset neoplasm., Results: A total of 23 studies met the inclusion criteria with a combined sample size of 57,911 participants. The meta-analysis revealed that the adverse event associated with semaglutide is gastrointestinal in nature (nausea and vomiting). No significant differences were observed between semaglutide and comparator groups., Conclusion: Semaglutide appears to have a favorable safety profile across diverse patient populations and treatment durations, supporting its continued use in the management of type 2 diabetes mellitus and obesity. It is generally well-tolerated, with a low incidence of adverse events. Clinicians should be aware of these findings and monitor patients accordingly. Further long-term studies are warranted to assess the safety of semaglutide in clinical practice.

Background: Heart failure (HF) is a major contributor to global health challenges, affecting mortality rates and healthcare expenditure. Glucagon-like peptide-1 receptor agonists (GLP-1RA) offer promise in HF management, though their precise impact is unclear. The main objective of this study was to evaluate the effect of semaglutide on HF-related outcomes., Methods: We conducted a meta-analysis of studies assessing the effects of semaglutide therapy on HF-related outcomes. This meta-analysis was performed according to PRISMA guidelines. Randomized clinical trials or observational cohorts studies with a follow-up duration ≥ 6 months were included. The random-effects model was performed., Results: Six randomised clinical trials (n = 28,762 patients) and two observational studies were identified and considered eligible for this systematic review. A total of 14,608 subjects were assigned to the semaglutide group and 14,716 individuals were assigned to control or placebo groups. Overall, this meta-analysis shows that semaglutide use was associated with an decreased risk of HF (OR: 0.74; 95 % CI: 0.58 to 0.94, I 2 45 %), compared to placebo or control groups. The analytical evaluation does not suggest publication bias, and the sensitivity analysis demonstrated that the result was robust., Conclusion: This meta-analysis demonstrates that the use of semaglutide is associated with a reduction in clinical events related to HF. As HF is a heterogeneous clinical condition, further studies will be necessary to analyze this association in different subgroups of patients., 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 © 2024 Elsevier Inc.

Aim: To compare the incidence of adverse events (AEs) related to antiobesity medications (AOMs; glucagon-like peptide-1 receptor agonists [GLP-1RAs] vs. non-GLP-1RAs) after bariatric surgery., Methods: This single-centre retrospective cohort included patients (aged 16-65 years) who had undergone laparoscopic Roux-en-Y gastric bypass or sleeve gastrectomy (cohort entry date) and initiated AOMs. Participants were categorized as users of US Food and Drug Administration (FDA)-approved, off-label, or GLP-1RA AOMs if documented as receiving the medication on or after cohort entry date. Non-GLP-1RA AOMs were phentermine, orlistat, topiramate, canagliflozin, dapagliflozin, empagliflozin, naltrexone, bupropion/naltrexone and phentermine/topiramate. GLP-1RA AOMs included: semaglutide, dulaglutide, exenatide and liraglutide. The primary outcome was AE incidence. Logistic regression was used to determine the association of AOM exposure with AEs., Results: We identified 599 patients meeting our inclusion criteria, 83% of whom were female. Their median (interquartile range [IQR]) age was 47.8 (40.9-55.4) years. The median duration of surgery to AOM exposure was 30 months. GLP-1RAs use was not associated with higher odds of AEs: adjusted odds ratio (aOR) 1.1 (95% confidence interval [CI] 0.5-2.6) and aOR 1.1 (95% CI 0.6-2.3) for GLP-1RA versus FDA-approved and off-label AOM use, respectively. AOM initiation ≥12 months after surgery was associated with lower risk of AEs compared to <12 months (aOR 0.01 [95% CI 0.0-0.01]; p < 0.001)., Conclusion: Our results showed that GLP-1RA AOMs were not associated with an increased risk of AEs compared to non-GLP-1RA AOMs in patients who had previously undergone bariatric surgery. Prospective studies are needed to identify the optimal timeframe for GLP-1RA initiation., (© 2024 The Author(s). Diabetes, Obesity and Metabolism published by John Wiley & Sons Ltd.)

Heart failure with preserved ejection fraction (HFpEF) is a growing clinical challenge with limited treatment options. This review explores the potential of semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist, for HFpEF treatment. Studies suggest promising benefits, including symptom improvement, weight management, and the potential for enhanced exercise capacity. However, the evidence for semaglutide's impact on exercise capacity and heart function remains inconclusive, and its anti-inflammatory effects require further investigation. The safety profile appears favorable, with gastrointestinal side effects being the most common adverse events. It is crucial to emphasize that additional research with longer follow-up, head-to-head comparisons, and exploration of optimal dosage and mechanisms of action are necessary to solidify semaglutide's role in HFpEF treatment. Semaglutide is promising to improve symptoms, promote weight loss, and potentially influence underlying HFpEF mechanisms. Future research can refine treatment strategies and unlock the full potential of semaglutide for this patient population., 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 © 2024.

Postpartum mothers and their healthcare providers often face the challenge of limited data regarding the safety of drug therapies during lactation. Pregnancy can lead to sustained weight gain, and obesity can negatively impact both physical and psychological well-being. The introduction of GLP-1 agonists to augment weight loss has become a topic of interest for many postpartum mothers. Our study aims to investigate the transmission of semaglutide into human milk in the first steps to ensure the safety and health of both lactating mothers and their breastfed infants. Semaglutide quantification was performed using high-resolution liquid chromatography-mass spectrometry. InfantRisk Center Human Milk biorepository released milk samples from eight women collected at 0, 12 and 24 h post-semaglutide administration. Semaglutide was extracted using protein precipitation in methanol, followed by chromatographic separation. Linear calibration curves for the method ranged between 2.5-30 ng/mL, with a limit of detection of 1.7 ng/mL and a limit of quantification of 5.7 ng/mL (LLOQ). Semaglutide was not detected in any of the collected human milk samples. A worst-case scenario of the relative infant dose (RID) was calculated using the LLOQ as the drug concentration in milk when considering semaglutide's bioavailability and long-acting dose profile. The maximum RID projected was 1.26%, far below the standard 10% safety threshold. While questions about long-term infant outcomes, the safety of maternal nutrient intake, and the nutrient content of breast milk remain, our findings suggest that semaglutide concentrations in human milk are unlikely to pose clinical concerns for breastfed infants. These results support healthcare providers in making informed decisions regarding postpartum therapeutic interventions.

Background: Semaglutide, a GLP-1 receptor agonist, reduces the risk of major adverse cardiovascular events (MACE) in people with overweight or obesity, but the effects of this drug on outcomes in patients with atherosclerotic cardiovascular disease and heart failure are unknown. We report a prespecified analysis of the effect of once-weekly subcutaneous semaglutide 2·4 mg on ischaemic and heart failure cardiovascular outcomes. We aimed to investigate if semaglutide was beneficial in patients with atherosclerotic cardiovascular disease with a history of heart failure compared with placebo; if there was a difference in outcome in patients designated as having heart failure with preserved ejection fraction compared with heart failure with reduced ejection fraction; and if the efficacy and safety of semaglutide in patients with heart failure was related to baseline characteristics or subtype of heart failure., Methods: The SELECT trial was a randomised, double-blind, multicentre, placebo-controlled, event-driven phase 3 trial in 41 countries. Adults aged 45 years and older, with a BMI of 27 kg/m 2 or greater and established cardiovascular disease were eligible for the study. Patients were randomly assigned (1:1) with a block size of four using an interactive web response system in a double-blind manner to escalating doses of once-weekly subcutaneous semaglutide over 16 weeks to a target dose of 2·4 mg, or placebo. In a prespecified analysis, we examined the effect of semaglutide compared with placebo in patients with and without a history of heart failure at enrolment, subclassified as heart failure with preserved ejection fraction, heart failure with reduced ejection fraction, or unclassified heart failure. Endpoints comprised MACE (a composite of non-fatal myocardial infarction, non-fatal stroke, and cardiovascular death); a composite heart failure outcome (cardiovascular death or hospitalisation or urgent hospital visit for heart failure); cardiovascular death; and all-cause death. The study is registered with ClinicalTrials.gov, NCT03574597., Findings: Between Oct 31, 2018, and March 31, 2021, 17 604 patients with a mean age of 61·6 years (SD 8·9) and a mean BMI of 33·4 kg/m 2 (5·0) were randomly assigned to receive semaglutide (8803 [50·0%] patients) or placebo (8801 [50·0%] patients). 4286 (24·3%) of 17 604 patients had a history of investigator-defined heart failure at enrolment: 2273 (53·0%) of 4286 patients had heart failure with preserved ejection fraction, 1347 (31·4%) had heart failure with reduced ejection fraction, and 666 (15·5%) had unclassified heart failure. Baseline characteristics were similar between patients with and without heart failure. Patients with heart failure had a higher incidence of clinical events. Semaglutide improved all outcome measures in patients with heart failure at random assignment compared with those without heart failure (hazard ratio [HR] 0·72, 95% CI 0·60-0·87 for MACE; 0·79, 0·64-0·98 for the heart failure composite endpoint; 0·76, 0·59-0·97 for cardiovascular death; and 0·81, 0·66-1·00 for all-cause death; all p interaction >0·19). Treatment with semaglutide resulted in improved outcomes in both the heart failure with reduced ejection fraction (HR 0·65, 95% CI 0·49-0·87 for MACE; 0·79, 0·58-1·08 for the composite heart failure endpoint) and heart failure with preserved ejection fraction groups (0·69, 0·51-0·91 for MACE; 0·75, 0·52-1·07 for the composite heart failure endpoint), although patients with heart failure with reduced ejection fraction had higher absolute event rates than those with heart failure with preserved ejection fraction. For MACE and the heart failure composite, there were no significant differences in benefits across baseline age, sex, BMI, New York Heart Association status, and diuretic use. Serious adverse events were less frequent with semaglutide versus placebo, regardless of heart failure subtype., Interpretation: In patients with atherosclerotic cardiovascular diease and overweight or obesity, treatment with semaglutide 2·4 mg reduced MACE and composite heart failure endpoints compared with placebo in those with and without clinical heart failure, regardless of heart failure subtype. Our findings could facilitate prescribing and result in improved clinical outcomes for this patient group., Funding: Novo Nordisk., Competing Interests: Declaration of interests JD declares having received consulting honoraria from Amgen, Boehringer Ingelheim, Merck, Pfizer, Aegerion, Novartis, Sanofi, Takeda, Novo Nordisk, and Bayer, and research grants from British Heart Foundation, Medical Research Council (UK), National Institute for Health and Care Research, Public Health England, MSD, Pfizer, Aegerion, Colgate, and Roche.

Importance: Obesity affects approximately 19% of women and 14% of men worldwide and is associated with increased morbidity. Antiobesity medications (AOMs) modify biological processes that affect appetite and significantly improve outcomes, such as type 2 diabetes, hypertension, and dyslipidemia., Observations: AOMs should be administered in combination with lifestyle interventions and can be classified according to their mechanisms of action. Orlistat modifies digestive tract absorption and causes gastrointestinal adverse effects, such as oily fecal spotting and urgency, in more than 25% of patients. Centrally acting drugs, such as phentermine-topiramate and naltrexone-bupropion, regulate appetite in the brain and are associated with constipation in approximately 20% of patients, although the incidence of other adverse effects (eg, paresthesia, nausea) varies by medication. Nutrient-stimulated hormone-based medications, such as liraglutide, semaglutide, and tirzepatide, mimic the actions of enteropancreatic hormones that modify central appetite regulation and provide multiple cardiometabolic weight-loss benefits. Adverse effects of these drugs include nausea (28%-44%), diarrhea (21%-30%), and constipation (11%-24%). The relative potency of adult obesity medications has been studied in meta-analyses. Compared with placebo, orlistat was associated with 3.1% greater weight loss (52 randomized clinical trials [RCTs]; 16 964 participants), phentermine-topiramate was associated with 8.0% greater weight loss (5 RCTs; 3407 participants), naltrexone-bupropion was associated with 4.1% greater weight loss (6 RCTs; 9949 participants), liraglutide was associated with 4.7% greater weight loss (18 RCTs; 6321 participants), semaglutide was associated with 11.4% greater weight loss (5 RCTs; 4421 participants), and tirzepatide 15 mg was associated with 12.4% greater weight loss (6 RCTs; 1972 participants)., Conclusion and Relevance: Obesity is associated with increased morbidity. Antiobesity medications are effective adjunctive therapy to lifestyle changes for improved weight loss and health outcomes.

Although, in randomized clinical trials, once-weekly subcutaneous semaglutide (OW s.c.) has demonstrated superior efficacy in comparison with placebo and active controls in terms of glycemic control and body weight reduction in patients with type 2 diabetes mellitus (T2DM), these results need to be confirmed in a real-world (RW) setting. An RW ambispective study (6 months retrospective and 6 months prospective) was conducted in 10 tertiary hospitals in Spain. We evaluated changes in HbA1c and body weight in patients with T2DM treated with semaglutide OW s.c. Additionally, we analyzed different subgroups of patients treated with semaglutide OW s.c. as an add-on to glucose-lowering therapy. A total of 752 patients with a mean age of 60.2 years, a mean HbA1c level of 8.5%, a mean body weight of 101.6 kg, and a mean T2DM duration of 10 years were included. At 12 months, compared with baseline, there was a mean difference of -2.1% in HbA1c levels ( p < 0.001) and a mean difference of 9.2 kg in body weight ( p < 0.001). Moreover, there were statistically significant differences ( p < 0.001) between baseline and month 12 in both HbA1c and body weight in the four subgroups receiving semaglutide OW s.c. as an add-on to glucose-lowering therapy. Semaglutide OW s.c. was well tolerated, with gastrointestinal disorders being the most commonly reported side effects. In this RW study, 12 months of treatment with semaglutide OW s.c. in patients with T2DM was associated with significant and clinically relevant improvements in glycemic control and weight loss, regardless of the glucose-lowering therapy received, and the overall safety profile was positive.

Nonarteritic anterior ischemic optic neuropathy (NAION) was first documented by a French physician Jean-Pierre Saint-Yves in 1817 (19th century). The clinical description of NAION was not known until 1935 when C. Miller Fischer thoroughly described it. Briefly, NAION is a rare (2.5-11.8 per 1,00,000 cases in men above 50 years) but serious condition that causes sudden painless loss of vision due to ischemia of the optic nerve. 1 It is more common in Caucasians compared with Asians and is associated with various risk factors such as hypertension, type 2 diabetes (T2D), smoking, hyperlipidemia, obesity, obstructive sleep apnea, small optic nerve cup ("disk at risk"), optic nerve drusen, and certain drugs, especially phosphodiesterase type 5 inhibitors (PDE-5I), amiodarone, and cabergoline. 2 Although the clinical development programs and real-world studies of semaglutide [a glucagon-like peptide-1 receptor agonist (GLP-1RA) approved for the treatment of T2D and obesity] did not report any significant increase in the risk of NAION, a recent retrospective cohort study suggested a possible link between NAION and semaglutide. 3 This editorial briefly summarizes the current knowledge about NAION and its relation to metabolic disorders, cardiovascular, and antidiabetes drugs and puts a perspective concerning semaglutide., (© Journal of the Association of Physicians of India 2024.)

Background: Obesity has been established as a significant risk factor for osteoarthritis. Anti-obesity medications (AOMs) have demonstrated efficacy in weight management. However, potential impact on osteoarthritis risk remains uncertain., Methods: This retrospective cohort study used Kythera data from NOV2022 to JULY2024. Patients with obesity using AOMs were identified through diagnosis and prescription claims for tirzepatide, semaglutide, or liraglutide between 1NOV2023 and 31JAN2024, with a 6-month follow-up to assess OA risk. OA risk, analyzed using Cox regression and propensity score matching, controlled for comorbidities and sociodemographic factors., Results: There were 39,394 patients living with obesity using AOM (23,933 semaglutide 12,854 tirzepatide, 2,607 liraglutide) and 72,405 without AOM use. The adjusted osteoarthritis risk was 27% % lower in AOM users than in non-users (hazard ratio (HR) = 073, 95% CI (0.67-0.79), p  < 0.01). Among AOMs, tirzepatide was associated with a significantly lower osteoarthritis (OA) risk compared to semaglutide (HR = 0.57, 95% CI: 0.50-0.65, p  < 0.0001). Liraglutide was linked to a significantly higher OA risk vs tirzepatide (HR = 1.63, 95% CI: 1.23-2.15, p  = 0.0007)., Conclusions: AOM use was associated with a significantly lower risk of OA and may be an effective obesity management intervention.

Background: Reports of reduced desire to smoke in patients treated with semaglutide, a glucagon-like peptide receptor agonist (GLP-1RA) medication for type 2 diabetes mellitus (T2DM) and obesity, have raised interest about its potential benefit for tobacco use disorders (TUDs)., Objective: To examine the association of semaglutide with TUD-related health care measures in patients with comorbid T2DM and TUD., Design: Emulation target trial based on a nationwide population-based database of patient electronic health records., Setting: United States, 1 December 2017 to 31 March 2023., Participants: Seven target trials were emulated among eligible patients with comorbid T2DM and TUD by comparing the new use of semaglutide versus 7 other antidiabetes medications (insulins, metformin, dipeptidyl-peptidase-4 inhibitors, sodium-glucose cotransporter-2 inhibitors, sulfonylureas, thiazolidinediones, and other GLP-1RAs)., Measurements: The TUD-related health care measures (medical encounter for diagnosis of TUD, smoking cessation medication prescriptions, and smoking cessation counseling) that occurred within a 12-month follow-up were examined using Cox proportional hazards and Kaplan-Meier survival analyses., Results: The study compared 222 942 new users of antidiabetes medications including 5967 of semaglutide. Semaglutide was associated with a significantly lower risk for medical encounters for TUD diagnosis compared with other antidiabetes medications, and was strongest compared with insulins (hazard ratio [HR], 0.68 [95% CI, 0.63 to 0.74]) and weakest but statistically significant compared with other GLP-1RAs (HR, 0.88 [CI, 0.81 to 0.96]). Semaglutide was associated with reduced smoking cessation medication prescriptions and counseling. Similar findings were observed in patients with and without a diagnosis of obesity. For most of the group comparisons, the differences occurred within 30 days of prescription initiation., Limitation: Documentation bias, residual confounding, missing data on current smoking behavior, body mass index, and medication adherence., Conclusion: Semaglutide was associated with lower risks for TUD-related health care measures in patients with comorbid T2DM and TUD compared with other antidiabetes medications including other GLP-1Ras, primarily within 30 days of prescription. These findings suggest the need for clinical trials to evaluate semaglutide's potential for TUD treatment., Primary Funding Source: National Institutes of Health., Competing Interests: Disclosures: Disclosures can be viewed at www.acponline.org/authors/icmje/ConflictOfInterestForms.do?msNum=M23-2718.

Aim: The trial (NCT04016974) investigated the pharmacokinetics, pharmacodynamics, safety and tolerability of oral semaglutide, the first orally administered glucagon-like peptide-1 analogue for type 2 diabetes, in healthy Chinese subjects., Materials and Methods: This single-centre, multiple-dose, placebo-controlled trial randomized 32 healthy Chinese adults to once-daily oral semaglutide (3 mg escalating to 14 mg) or placebo for 12 weeks. Blood samples were collected regularly during treatment and follow-up. The primary endpoint was the area under the semaglutide concentration-time curve over a dosing interval (0-24 h) at steady state (AUC 0-24h,sema,SS ). Secondary pharmacokinetic endpoints included the maximum observed semaglutide plasma concentration at steady state (C max,sema,SS ). Supportive secondary pharmacodynamics endpoints included changes in body weight and fasting plasma glucose., Results: Treatment with all oral semaglutide doses showed dose-dependent increases in semaglutide exposure in healthy Chinese subjects at steady state, determined by AUC 0-24h,sema,SS (233, 552 and 1288 h·nmol/L for 3, 7 and 14 mg of oral semaglutide, respectively) and C max,sema,SS . Oral semaglutide treatment was associated with significant reductions in body weight (p = .0001) and fasting plasma glucose (p = .0011) versus placebo at the end of treatment. The safety and tolerability of oral semaglutide were consistent with the known profile of glucagon-like peptide-1 receptor agonists, with no severe or blood-glucose-confirmed symptomatic hypoglycaemic events, serious adverse events or deaths. The most frequent adverse events were gastrointestinal disorders., Conclusions: At steady state, oral semaglutide exposure was dose dependent and close to dose proportionality in healthy Chinese subjects. This is consistent with previous clinical pharmacology results for oral semaglutide., (© 2024 The Authors. Diabetes, Obesity and Metabolism published by John Wiley & Sons Ltd.)

Purpose of Review: The purpose of this review is to describe the existing limited data related to the use of semaglutide in adolescents with obesity, supplementing with findings from adult studies of semaglutide use., Recent Findings: Semaglutide, as a once weekly subcutaneous injection for weight management, effectively reduces body mass index (BMI) while improving hyperglycemia, elevated alanine aminotransferase levels, hyperlipidemia, and quality of life in youth with obesity. As of this review, only one large randomized clinical trial of semaglutide in youth has been completed, with a follow-up duration of 68 weeks. Thus, long-term data on the safety in adolescents is limited, particularly regarding the risks of cholelithiasis, pancreatitis, suicidal ideation, and disordered eating. Due to the cost of semaglutide, particularly in the United States, limited cost effectiveness analyses have demonstrated unfavorable incremental cost-effectiveness ratios for semaglutide relative to phentermine-topiramate as an alternative antiobesity medication in adolescents., Summary: Semaglutide represents an important advance in the pediatric obesity management, with clear short-term reductions in BMI and improvement in metabolic parameters. However, its long-term safety and efficacy for youth with obesity remain to be demonstrated. Additional research is needed to assess trends in utilization and adherence to minimize the risk of worsening socioeconomic disparities in pediatric obesity., (Copyright © 2024 Wolters Kluwer Health, Inc.

Importance: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have gained use primarily due to their weight-reduction effects, although a regulatory review was undertaken for potential suicidality concern., Objectives: To evaluate potential signals for suicidal and self-injurious adverse drug reactions (ADRs) associated with the GLP-1 RAs semaglutide and liraglutide., Design, Setting, and Participants: Disproportionality analysis through the case-control design using the World Health Organization (WHO) global database of suspected ADRs. Participants were clinical patients worldwide experiencing an ADR suspectedly attributable to semaglutide or liraglutide in the database from inception to August 30, 2023. Data were analyzed from September to December 2023., Exposure: Treatment with semaglutide or liraglutide regardless of indication or treatment duration., Main Outcomes and Measures: Reporting odds ratio (ROR) and the bayesian information component (IC) with 95% CIs were calculated as measures of disproportionate reporting of suicidal and self-injurious ADRs associated with semaglutide and liraglutide compared with all other medications. Sensitivity analyses were conducted including patients with coreported use of antidepressants and benzodiazepines and using dapagliflozin, metformin, and orlistat as comparators. A disproportionality signal was considered when the lower limits of the ROR and IC were above 1 and 0, respectively., Results: A total of 107 (median [IQR] age 48 [40-56] years; 59 female patients [55%]) and 162 (median [IQR] age 47 [38-60] years; 100 female patients [61%]) cases of suicidal and/or self-injurious ADRs were reported between November 2000 and August 2023 with semaglutide and liraglutide, respectively. Significant disproportionality was detected only for semaglutide-associated suicidal ideation (ROR, 1.45; 95% CI, 1.18-1.77; IC, 0.53; 95% CI, 0.19-0.78), which remained significant in patients with coreported use of antidepressants (ROR, 4.45; 95% CI, 2.52-7.86; IC, 1.96; 95% CI, 0.98-2.63) and benzodiazepines (ROR, 4.07; 95% CI, 1.69-9.82; IC, 1.67; 95% CI, 0.11-2.65), when compared with dapagliflozin (ROR, 5.56; 95% CI, 3.23-9.60; IC, 0.70; 95% CI, 0.36-0.95), metformin (ROR, 3.86; 95% CI, 2.91-5.12; IC, 1.20; 95% CI, 0.94-1.53) and orlistat (ROR, 4.24; 95% CI, 2.69-6.69; IC, 0.70; 95% CI, 0.36-0.95)., Conclusions and Relevance: This study using the WHO database found a signal of semaglutide-associated suicidal ideation, which warrants urgent clarification.

Aim: To assess the efficacy and safety of dulaglutide 1.5 mg versus dulaglutide 0.75 mg in Japanese participants with type 2 diabetes (T2D)., Materials and Methods: A Phase 3, multicentre, randomized, double-blind, parallel-group study was conducted in Japanese participants aged ≥20 years, with T2D for ≥6 months and inadequate glycaemic control, while on a single oral antihyperglycaemic medication (NCT04809220). The primary objective was to evaluate superiority of dulaglutide 1.5 mg versus dulaglutide 0.75 mg measured by mean change in glycated haemoglobin (HbA1c) from baseline to 26 weeks. Other efficacy and safety endpoints were evaluated at 26 and 52 weeks. All statistical analyses were conducted using the intention-to-treat population., Results: Overall, 591 participants were randomized to once-weekly dulaglutide 1.5 mg or 0.75 mg. At Week 26, dulaglutide 1.5 mg was superior to dulaglutide 0.75 mg in HbA1c reduction from baseline (least squares mean [LSM] difference -0.29% [95% confidence interval {CI} -0.43, -0.14]). At Week 52, the dulaglutide 1.5-mg arm had a significantly greater proportion of participants who achieved HbA1c <7.0% (46.3% vs. 38.5%; p = 0.03) and showed significantly greater reduction in fasting serum glucose (LSM difference -9.4 mg/dL [95% CI -14.4, -4.3]; p < 0.001) versus the dulaglutide 0.75-mg arm. No statistically significant change in body weight was observed in either treatment arm. Overall, 442 participants (75.4%) experienced treatment emergent adverse events (TEAEs). Constipation (11.3%), diarrhoea (9.6%) and pyrexia (9.0%) were the most commonly reported TEAEs., Conclusions: Dulaglutide 1.5 mg once weekly demonstrated superior glycaemic control versus dulaglutide 0.75 mg once weekly, with comparable safety and tolerability, in Japanese people with T2D., (© 2024 The Authors.

Background: HIV-associated lipohypertrophy, which is characterised by an abnormal accumulation of abdominal visceral adipose tissue, remains problematic in people with HIV. Effective interventions are lacking, despite HIV-associated lipohypertrophy carrying a substantial risk of cardiometabolic comorbidity. The primary aim of this trial was to investigate effects of the GLP-1 receptor agonist, semaglutide, on adipose tissue in HIV-associated lipohypertrophy., Methods: This randomised, double-blind, placebo-controlled phase 2b clinical trial was conducted at a single US site. Key inclusion criteria included people with HIV aged 18 years or older with controlled HIV-1, a BMI of 25 kg/m 2 or more, and lipohypertrophy but without type 1 or type 2 diabetes. Participants were randomly assigned 1:1 to receive 32 weeks of once-weekly subcutaneous semaglutide (8-week dose titration and 24 weeks at 1·0 mg) or placebo; all research personnel and participants remained masked to treatment assignment. Primary outcomes were changes at 32 weeks in adipose tissue quantity by body compartment. Analyses, including safety, were performed using intention-to-treat principles. This trial was registered ClinicalTrials.gov (NCT04019197) and is complete., Findings: Between June 10, 2019, and July 28, 2022, 108 participants were randomly assigned to receive semaglutide (n=54) or placebo (n=54). Eight (15%) in each group withdrew prematurely. Significant effects of semaglutide were seen over the 32-week study period in sex-adjusted multiplicative regression analyses for the primary outcome, abdominal visceral adipose tissue (β -30·82 cm 2 , 95% CI -50·13 to -11·51; % change -30·6%). Decreases were also seen in other key measures, including abdominal subcutaneous adipose tissue (β -42·01 cm 2 , 95% CI -75·49 to -8·52; % change -11·2%) and total body fat (natural logarithmic -0·21 kg, 95% CI -0·33 to -0·08; % change -18·9%). There were no statistically significant differences in possibly related or related adverse events (absolute risk difference 0·1111, 95% CI -0·0727 to 0·2869); however, one semaglutide-related grade 4 elevated lipase and two possibly related cases of cholelithiasis (grades 1 and 2) were observed., Interpretation: Semaglutide holds promise as an effective treatment for HIV-associated lipohypertrophy. The potential risk of serious adverse events deserves further scrutiny in large trials in people with HIV., Funding: National Institutes of Health., Competing Interests: Declaration of interests ARE served as an advisor for Gilead Sciences and Theratechnologies.

Objective: This prospective study aimed to describe the clinical course in terms of glycemic outcomes, body weight, and adverse events during the first 12 weeks following a switch from glucagon-like peptide-1 receptor agonists (GLP-1 RAs) directly to tirzepatide 5 mg., Methods: Participants were ≥18 years with type 2 diabetes (T2D), glycated hemoglobin (HbA1c) ≥6.5% to ≤9.0%, body mass index ≥25 kg/m 2 and were on a stable treatment dose of GLP-1 RAs (liraglutide every day [1.2, 1.8 mg], semaglutide once-weekly [0.5, 1.0, 2.0 mg], or dulaglutide once-weekly [0.75, 1.5, 3.0, and 4.5 mg]) for ≥3 months at baseline. The primary end point was HbA1c change from baseline at week 12. Secondary end points included change from baseline in fasting serum glucose, body weight, and glucose assessed by continuous glucose monitoring. Safety was also assessed., Results: Participants were 58.3 years on average, with baseline HbA1c 7.39%, body mass index 35.18 kg/m 2 , T2D duration around 12.4 years, and included 55% females. Semaglutide (55%) and dulaglutide (42%) were the most commonly used GLP-1 RAs at baseline with semaglutide 1.0 mg and dulaglutide 1.5 mg being the most common treatment doses. At week 12, mean HbA1c changed from baseline by -0.43%, fasting serum glucose by -7.83 mg/dL, and body weight by -2.15 kg (all P < .01). Glycemic outcomes and body weight improved in participants in all baseline GLP-1 RA subgroups. Twenty participants (13.2%) developed gastrointestinal events. Three (2%) participants discontinued tirzepatide due to adverse events. There were no severe hypoglycemic events or deaths., Conclusion: In this prospective study, when people with T2D on stable GLP-1 RA treatment were switched directly to tirzepatide 5 mg, they experienced improved glycemic outcomes and additional weight reduction with an acceptable risk of adverse gastrointestinal events over 12 weeks., Competing Interests: Disclosure S.J. reports consultancy fees from Eli Lilly and Company and Sanofi.

Importance: Anecdotal experience raised the possibility that semaglutide, a glucagon-like peptide 1 receptor agonist (GLP-1 RA) with rapidly increasing use, is associated with nonarteritic anterior ischemic optic neuropathy (NAION)., Objective: To investigate whether there is an association between semaglutide and risk of NAION., Design, Setting, and Participants: In a retrospective matched cohort study using data from a centralized data registry of patients evaluated by neuro-ophthalmologists at 1 academic institution from December 1, 2017, through November 30, 2023, a search for International Statistical Classification of Diseases and Related Health Problems, Tenth Revision code H47.01 (ischemic optic neuropathy) and text search yielded 16 827 patients with no history of NAION. Propensity matching was used to assess whether prescribed semaglutide was associated with NAION in patients with type 2 diabetes (T2D) or overweight/obesity, in each case accounting for covarying factors (sex, age, systemic hypertension, T2D, obstructive sleep apnea, obesity, hyperlipidemia, and coronary artery disease) and contraindications for use of semaglutide. The cumulative incidence of NAION was determined with the Kaplan-Meier method and a Cox proportional hazards regression model adjusted for potential confounding comorbidities. Data were analyzed from December 1, 2017, through November 30, 2023., Exposures: Prescriptions for semaglutide vs non-GLP-1 RA medications to manage either T2D or weight., Main Outcomes and Measures: Cumulative incidence and hazard ratio of NAION., Results: Among 16 827 patients, 710 had T2D (194 prescribed semaglutide; 516 prescribed non-GLP-1 RA antidiabetic medications; median [IQR] age, 59 [49-68] years; 369 [52%] female) and 979 were overweight or obese (361 prescribed semaglutide; 618 prescribed non-GLP-1 RA weight-loss medications; median [IQR] age, 47 [32-59] years; 708 [72%] female). In the population with T2D, 17 NAION events occurred in patients prescribed semaglutide vs 6 in the non-GLP-1 RA antidiabetes cohort. The cumulative incidence of NAION for the semaglutide and non-GLP-1 RA cohorts over 36 months was 8.9% (95% CI, 4.5%-13.1%) and 1.8% (95% CI, 0%-3.5%), respectively. A Cox proportional hazards regression model showed higher risk of NAION for patients receiving semaglutide (hazard ratio [HR], 4.28; 95% CI, 1.62-11.29); P < .001). In the population of patients who were overweight or obese, 20 NAION events occurred in the prescribed semaglutide cohort vs 3 in the non-GLP-1 RA cohort. The cumulative incidence of NAION for the semaglutide vs non-GLP-1 RA cohorts over 36 months was 6.7% (95% CI, 3.6%-9.7%) and 0.8% (95% CI, 0%-1.8%), respectively. A Cox proportional hazards regression model showed a higher risk of NAION for patients prescribed semaglutide (HR, 7.64; 95% CI, 2.21-26.36; P < .001)., Conclusions and Relevance: This study's findings suggest an association between semaglutide and NAION. As this was an observational study, future study is required to assess causality.

Background: Oral semaglutide in older subjects with type 2 diabetes was as effective as in younger subjects, according to phase 3 clinical trials. However, its efficacy can be limited in very aged population, due to the presence of impaired cognitive function and the complex instructions for its use. Here, we investigated its efficacy and safety by further age bracket in older subjects in real-world., Methods: We retrospectively studied subjects > 65 years of age with type 2 diabetes who started oral semaglutide treatment. The primary outcome was the change in glycated hemoglobin (HbA1c) over 6 months. Adverse events and cognitive function were evaluated using the Common Terminology Criteria for Adverse Events (CTCAE) and the Hasegawa Dementia Rating Scale-revised (HDS-R). The achievement rate of glycemic targets was evaluated based on the age, health status of subjects and their use of anti-diabetic agents which can cause hypoglycemia, with additional analysis between two subgroups; early (65-74) versus late (≥ 75) older. Furthermore, we evaluated the relationships between their improvements in HbA1c and the baseline characteristics of the subjects, including their cognitive function and insulin secretory capacity., Results: We studied the efficacy of the drug in 24 subjects. Their HbA1c and body weight significantly decreased (- 13.1 ± 7.5 mmol/mol and - 3.0 ± 2.4 kg, respectively; P < 0.01). Although cognitive function was lower in the late older group (r = -0.57, P < 0.01), changes in HbA1c showed no difference between the two subgroups (P = 0.66) and it correlated with the insulin secretory capacity rather than cognitive function (r = -0.49, P < 0.05). Glycemic targets were more likely to be achieved (P < 0.01), but HbA1c excessively decreased in late older subjects who were also using insulin or an insulin secretagogue. The frequency of adverse events was similar to that in the clinical trial, whereas discontinuation of medication were more frequent among the late older subjects (Early; n = 2, Late; n = 4)., Conclusions: Oral semaglutide improves the glycemic control of older subjects, but it might be a risk for potential hypoglycemia and discontinuation because of adverse events in subjects of ≥ 75 years.

Background: Patients with type 2 diabetes and chronic kidney disease are at high risk for kidney failure, cardiovascular events, and death. Whether treatment with semaglutide would mitigate these risks is unknown., Methods: We randomly assigned patients with type 2 diabetes and chronic kidney disease (defined by an estimated glomerular filtration rate [eGFR] of 50 to 75 ml per minute per 1.73 m 2 of body-surface area and a urinary albumin-to-creatinine ratio [with albumin measured in milligrams and creatinine measured in grams] of >300 and <5000 or an eGFR of 25 to <50 ml per minute per 1.73 m 2 and a urinary albumin-to-creatinine ratio of >100 and <5000) to receive subcutaneous semaglutide at a dose of 1.0 mg weekly or placebo. The primary outcome was major kidney disease events, a composite of the onset of kidney failure (dialysis, transplantation, or an eGFR of <15 ml per minute per 1.73 m 2 ), at least a 50% reduction in the eGFR from baseline, or death from kidney-related or cardiovascular causes. Prespecified confirmatory secondary outcomes were tested hierarchically., Results: Among the 3533 participants who underwent randomization (1767 in the semaglutide group and 1766 in the placebo group), median follow-up was 3.4 years, after early trial cessation was recommended at a prespecified interim analysis. The risk of a primary-outcome event was 24% lower in the semaglutide group than in the placebo group (331 vs. 410 first events; hazard ratio, 0.76; 95% confidence interval [CI], 0.66 to 0.88; P = 0.0003). Results were similar for a composite of the kidney-specific components of the primary outcome (hazard ratio, 0.79; 95% CI, 0.66 to 0.94) and for death from cardiovascular causes (hazard ratio, 0.71; 95% CI, 0.56 to 0.89). The results for all confirmatory secondary outcomes favored semaglutide: the mean annual eGFR slope was less steep (indicating a slower decrease) by 1.16 ml per minute per 1.73 m 2 in the semaglutide group (P<0.001), the risk of major cardiovascular events 18% lower (hazard ratio, 0.82; 95% CI, 0.68 to 0.98; P = 0.029), and the risk of death from any cause 20% lower (hazard ratio, 0.80; 95% CI, 0.67 to 0.95, P = 0.01). Serious adverse events were reported in a lower percentage of participants in the semaglutide group than in the placebo group (49.6% vs. 53.8%)., Conclusions: Semaglutide reduced the risk of clinically important kidney outcomes and death from cardiovascular causes in patients with type 2 diabetes and chronic kidney disease.

Aim: To determine if the dispensing of glucagon-like peptide (GLP)-1 receptor agonists is associated with increased dispensing of antidepressants., Materials and Methods: We used cross-sectional, case-control and retrospective cohort study designs to examine the association between dispensed GLP-1 receptor agonists and antidepressants between 2012 and 2022 in the 10% random sample of the Australian Pharmaceutical Benefits Scheme (PBS) data. PBS-listed GLP-1 receptor agonists, exenatide, dulaglutide and semaglutide were the exposures. Outcomes were the odds ratio [ORs; 99% confidence interval (CI)] and hazard ratio (99% CI) of being dispensed any antidepressant. Analyses were adjusted for demographic measures and the dispensing of medicines to manage cardiovascular diseases or anxiety/insomnia. Statistical tests were two-sided at the 1% level of significance., Results: In total, 358 075 of 1 746 391 individuals were dispensed antidepressants, and 8495 of the 24 783 dispensed a GLP-1 receptor agonist were also dispensed an antidepressant in 2022 (OR 1.44; 99% CI 1.38-1.50); 24 103 of the 1 746 391 participants had been dispensed a GLP-1 receptor agonist between 2012 and 2021, and of these 8083 were dispensed antidepressants in 2022 (OR 1.52; 99% CI 1.46-1.59). The 2012 cohort included 1 213 316 individuals who had not been dispensed antidepressants that year. The hazard ratio of being dispensed an antidepressant between 2013 and 2022 following the dispensing of a GLP-1 receptor agonist was 1.19 (99% CI 1.12-1.27). Additional analyses restricting the time of exposure confirmed these associations for all PBS-listed GLP-1 receptor agonists., Conclusions: Individuals exposed to GLP-1 receptor agonists are at greater risk of being dispensed antidepressants. The possible impact of GLP-1 receptor agonists on the mood of consumers requires ongoing vigilance and further research., (© 2024 The Authors.

Aims/hypothesis: We conducted a systematic review and network meta-analysis to compare the efficacy and safety of s.c. administered tirzepatide vs s.c. administered semaglutide for adults of both sexes with type 2 diabetes mellitus., Methods: We searched PubMed and Cochrane up to 11 November 2023 for RCTs with an intervention duration of at least 12 weeks assessing s.c. tirzepatide at maintenance doses of 5 mg, 10 mg or 15 mg once weekly, or s.c. semaglutide at maintenance doses of 0.5 mg, 1.0 mg or 2.0 mg once weekly, in adults with type 2 diabetes, regardless of background glucose-lowering treatment. Eligible trials compared any of the specified doses of tirzepatide and semaglutide against each other, placebo or other glucose-lowering drugs. Primary outcomes were changes in HbA 1c and body weight from baseline. Secondary outcomes were achievement of HbA 1c target of ≤48 mmol/mol (≤6.5%) or <53 mmol/mol (<7.0%), body weight loss of at least 10%, and safety outcomes including gastrointestinal adverse events and severe hypoglycaemia. We used version 2 of the Cochrane risk-of-bias tool (ROB 2) to assess the risk of bias, conducted frequentist random-effects network meta-analyses and evaluated confidence in effect estimates utilising the Confidence In Network Meta-Analysis (CINeMA) framework., Results: A total of 28 trials with 23,622 participants (44.2% female) were included. Compared with placebo, tirzepatide 15 mg was the most efficacious treatment in reducing HbA 1c (mean difference -21.61 mmol/mol [-1.96%]) followed by tirzepatide 10 mg (-20.19 mmol/mol [-1.84%]), semaglutide 2.0 mg (-17.74 mmol/mol [-1.59%]), tirzepatide 5 mg (-17.60 mmol/mol [-1.60%]), semaglutide 1.0 mg (-15.25 mmol/mol [-1.39%]) and semaglutide 0.5 mg (-12.00 mmol/mol [-1.09%]). In between-drug comparisons, all tirzepatide doses were comparable with semaglutide 2.0 mg and superior to semaglutide 1.0 mg and 0.5 mg. Compared with placebo, tirzepatide was more efficacious than semaglutide for reducing body weight, with reductions ranging from 9.57 kg (tirzepatide 15 mg) to 5.27 kg (tirzepatide 5 mg). Semaglutide had a less pronounced effect, with reductions ranging from 4.97 kg (semaglutide 2.0 mg) to 2.52 kg (semaglutide 0.5 mg). In between-drug comparisons, tirzepatide 15 mg, 10 mg and 5 mg demonstrated greater efficacy than semaglutide 2.0 mg, 1.0 mg and 0.5 mg, respectively. Both drugs increased incidence of gastrointestinal adverse events compared with placebo, while neither tirzepatide nor semaglutide increased the risk of serious adverse events or severe hypoglycaemia., Conclusions/interpretation: Our data show that s.c. tirzepatide had a more pronounced effect on HbA 1c and weight reduction compared with s.c. semaglutide in people with type 2 diabetes. Both drugs, particularly higher doses of tirzepatide, increased gastrointestinal adverse events., Registration: PROSPERO registration no. CRD42022382594., (© 2024. The Author(s).)
