Semaglutide versus placebo in patients with heart failure and mildly reduced or preserved ejection fraction: a pooled analysis of the SELECT, FLOW, STEP-HFpEF, and STEP-HFpEF DM randomised trials.

BACKGROUND: Heart failure with mildly reduced or preserved ejection fraction (hereafter referred to as HFpEF) is the most common type of heart failure and is associated with a high risk of hospitalisation and death, especially in patients with overweight, obesity, or type 2 diabetes. In the STEP-HFpEF and STEP-HFpEF DM trials, semaglutide improved heart failure-related symptoms and physical limitations in participants with HFpEF. Whether semaglutide also reduces clinical heart failure events in this group remains to be established. METHODS: We conducted a post-hoc pooled, participant-level analysis of four randomised, placebo-controlled trials (SELECT, FLOW, STEP-HFpEF, and STEP-HFpEF DM) to examine the effects of once-weekly subcutaneous semaglutide (2·4 mg in SELECT, STEP-HFpEF, and STEP-HFpEF DM; 1·0 mg in FLOW) on heart failure events. The STEP-HFpEF and STEP-HFpF DM trials enrolled participants with obesity-related HFpEF, the SELECT trial enrolled participants with atherosclerotic cardiovascular disease and overweight or obesity, and the FLOW trial enrolled participants with type 2 diabetes and chronic kidney disease. Hence, for this analysis, we include all participants from the STEP-HFpEF trials and those with an investigator-reported history of HFpEF from SELECT and FLOW. The main outcomes for this analysis were the composite endpoint of time to cardiovascular death or first worsening heart failure event (defined as hospitalisation or urgent visit due to heart failure), time to first worsening heart failure event, and time to cardiovascular death. Efficacy and safety endpoints were analysed with the full analysis set (ie, all participants randomly assigned to treatment, according to the intention-to-treat principle). The SELECT, FLOW, STEP-HFpEF, and STEP-HFpEF DM trials are registered at ClinicalTrials.gov, NCT03574597, NCT03819153, NCT04788511, and NCT04916470, respectively, and all are complete. FINDINGS: Across the four trials, 3743 (16·8%) of 22 282 participants had a history of HFpEF (1914 assigned to semaglutide and 1829 assigned to placebo). In this group of participants with HFpEF, semaglutide reduced the risk of the combined endpoint of cardiovascular death or heart failure events (103 [5·4%] of 1914 in the semaglutide group had events vs 138 [7·5%] of 1829 in the placebo group; hazard ratio [HR] 0·69 [95% CI 0·53-0·89]; p=0·0045). Semaglutide also reduced the risk of worsening heart failure events (54 [2·8%] vs 86 [4·7%]; HR 0·59 [0·41-0·82]; p=0·0019). No significant effect on cardiovascular death alone was seen (59 [3·1%] vs 67 [3·7%]; HR 0·82 [0·57-1·16]; p=0·25). A lower proportion of patients treated with semaglutide had serious adverse events than did those who were treated with placebo (572 [29·9%] vs 708 [38·7%]). INTERPRETATION: In patients with HFpEF, semaglutide reduced the risk of the combined endpoint of cardiovascular death or worsening heart failure events, and worsening heart failure events alone, whereas its effect on cardiovascular death alone was not significant. These data support the use of semaglutide as an efficacious therapy to reduce the risk of clinical heart failure events in patients with HFpEF, for whom few treatment options are currently available.

Improved Clinical Outcomes with the Combination Therapy of a Glucagon-like Peptide-1 Receptor Agonists and a Sodium-glucose Cotransporter-2 Inhibitor in Overweight/Obese People with Type 2 Diabetes: Real-world Evidence from the Indian Subcontinent.

OBJECTIVE: Type 2 diabetes (T2D) mellitus is increasing exponentially in India, with overweight/obesity being prime contributors. This study aimed at assessing the clinical impact of the combination therapy of a glucagon-like peptide-1 receptor agonist (GLP-1RA) injection (inj.) and a sodium-glucose cotransporter-2 inhibitor (SGLT-2i) in overweight/obese patients from the Indian subcontinent. METHODS: In two real-world evidence (RWE) studies (RWE1 and 2), we retrospectively observed the effect of the combination therapy of a GLP-1RA, injection dulaglutide (DU) 1.5 mg/week, and an SGLT-2i, canagliflozin (CAN) 100 mg/day at weeks 16, 32, and 52 on HbA1c, body weight (weight), systolic blood pressure (SBP), lipids, change in doses of antidiabetic agents (ADA) and antihypertensive agents (AHA) in overweight/obese Asian Indian subjects with T2D, who had suboptimal glycemic control. RESULTS: A total of 95 T2D patients [51 males (M), 44 females (F)] completed the two RWE studies. In RWE 1, 40 patients (20 M/20 F), mean [standard deviation (SD)] age 49.4 (10.7) years (Y), weight 92.6 (6.6) kg, body mass index (BMI) 30.6 (2.3) kg/m2, duration of T2D 8.1 (3.2) Y, completed the study. At week 32, the mean (SD) reduction in A1c (%) was -1.3% [8.4 (0.7) to 7.1 (0.3); p < 0.01] and mean (SD) weight (kg) loss was -5.5 [92.6 (6.6) to 87.9 (7.02); p < 0.00001]. This group was then followed up until week 52. In RWE 2, 55 patients (31 M/24 F), age 51 (5.8) Y, weight 92.6 ± 3.4 kg, BMI 31.1 ± 2.1 kg/m2, SBP 142.4 ± 3.9 mm Hg, estimated glomerular filtration rate (eGFR) 62 ± 5 mL/minute/1.73 m2, with 8.4 ± 3.3 Y duration of diabetes met the inclusion criteria. In 71% of subjects, A1c decreased by -1.4% [8.5 ± 0.4 to 7.1 ± 0.2; p < 0.0001] at week 16 and was 6.8 ± 0.3 (p = 0.0002) in 18% at week 32. CONCLUSION: A statistically significant (SS) improvement in glycemic control, weight, and improvement in cardiovascular (CV) risk factors was observed with the GLP-1RA/SGLT-2i combination, which was well tolerated.

Effect of Semaglutide on Physical Function, Body Composition, and Biomarkers of Aging in Older Adults With Overweight and Insulin Resistance: Protocol for an Open-Labeled Randomized Controlled Trial.

BACKGROUND: Older adults with type 2 diabetes mellitus (T2DM) or prediabetes are at increased risk of adverse changes in body composition, physical function, and aging-related biomarkers compared to those with normal glucose tolerance. Semaglutide is a glucagon-like peptide 1 receptor agonist that has been approved for T2DM and chronic weight management. Although semaglutide is effective for weight loss and T2DM management, its effects on lean body mass, physical function, and biomarkers of aging are understudied in older adults. OBJECTIVE: This study aims to compare the effects of lifestyle counseling with and that without semaglutide on body composition, physical function, and biomarkers of aging in older adults. METHODS: This is an open-label randomized controlled trial. A total of 20 adults (aged 65 years and older) with elevated BMI (27-40 kg/m2) and prediabetes or well-controlled T2DM (hemoglobin A1c 5.7%-7.5%) are recruited, stratified by sex, and randomized 1:1 to one of 2 groups (semaglutide plus lifestyle counseling vs lifestyle counseling alone) and followed up for 5 months. Those in the semaglutide group are titrated to 1 mg weekly, as tolerated, for 12 weeks. Lifestyle counseling is given by registered dietitians and based on the Diabetes Prevention Program Lifestyle Change Program. Our primary outcomes include changes in lean mass, physical function, and biomarkers of aging. Body composition is measured by dual-energy x-ray absorptiometry and includes total fat mass and lean mass. Physical function is measured by 6-minute walk distance, grip strength, and short physical performance battery. Biomarkers of aging are measured in blood, skeletal muscle, and abdominal adipose tissue to include C-reactive protein, interleukin-6, tumor necrosis factors α, and ß galactosidase staining. RESULTS: The study was funded in December 2021 with a projected data collection period from spring 2023 through summer 2024. CONCLUSIONS: Despite the elevated risk of adverse changes in body composition, physical function, and biomarkers of aging among older adults with glucose intolerance and elevated adiposity, the benefits and risks of commonly prescribed antihyperglycemic or weight loss medications such as semaglutide are understudied. This study aims to fill this knowledge gap to inform clinicians about the potential for additional clinically meaningful, nonglycemic effects of semaglutide.

Weight Loss Pharmacotherapy: Current and Future Therapies.

The rising prevalence of obesity is of major concern. There are currently 5 Food and Drug Administration-approved medications for the treatment of obesity: orlistat, phentermine/topiramate, naltrexone/bupropion, liraglutide 3.0 mg, and semaglutide 2.4 mg. Surgical options such as bariatric surgery and endoscopic surgery induce more durable weight loss than pharmacotherapy or lifestyle interventions alone. However, patients often experience weight regain and weight loss plateau after surgery. The addition of multimodal or multihormonal pharmacotherapy is a promising tool to address these challenges. The optimal timing of obesity pharmacotherapy with surgical and endoscopic interventions requires further investigation.

[GLP-1 receptor agonists : impact on diabetic kidney disease]. / Agonistes des récepteurs du GLP-1 : ­impact sur la maladie rénale diabétique.

In addition to optimal glycemic control and management of other factors aggravating the pathology (hypertension, dyslipidemia, -obesity), the cornerstone of treatment of diabetic kidney disease (DKD) includes blockers of the renin-angiotensin system, sodium-glucose cotransporter 2 inhibitors or nonsteroidal antagonists of the mineralocorticoid receptor (finerenone). Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are recommended in the treatment of high-risk patients with type 2 diabetes (T2DM) to reduce cardiovascular (CV) risk. Data from CV studies indicate a nephroprotective effect of certain GLP-1 RAs in T2DM patients with DKD. The FLOW study published in May 2024, analyzing the impact of semaglutide vs placebo on renal events as primary outcome, confirms this renal protection of GLP-1 RAs.

Outre le contrôle glycémique et la prise en charge d'autres ­facteurs d'aggravation de la pathologie, la pierre angulaire du traitement de la maladie rénale diabétique (MRD) comprend les bloqueurs du système rénine-angiotensine, les inhibiteurs du cotransporteur sodium-glucose de type 2 ou encore la finérénone (antagoniste de l'aldostérone). Les agonistes du récepteur du glucagon-like peptide-1 (ARGLP-1) sont recommandés dans le traitement des patients avec un diabète de type 2 (DT2) à haut risque afin de réduire le risque cardiovasculaire (CV). Les ­données provenant des études CV indiquent un effet néphro­protecteur de certains ARGLP-1 chez les patients DT2 avec MRD. L'étude FLOW, publiée fin mai 2024 et analysant l'impact du sémaglutide sur les événements rénaux comme critère principal, confirme cette protection rénale des ARGLP-1.

One-Year Weight Reduction With Semaglutide or Liraglutide in Clinical Practice.

Importance: Limited data are available on long-term weight loss achieved with semaglutide or liraglutide for type 2 diabetes (T2D) or obesity in clinical practice. Objective: To document weight loss achieved with injectable forms of semaglutide or liraglutide and identify factors associated with weight reduction of 10% or greater at 1 year. Design, Setting, and Participants: This retrospective cohort study used electronic health records from a large, integrated health system in Ohio and Florida. Participants included adults with a body mass index (calculated as the weight in kilograms divided by the height in meters squared) of at least 30.0 who initiated treatment with semaglutide or liraglutide between July 1, 2015, and June 30, 2022. Follow-up was completed July 28, 2023. Exposure: Injectable forms of semaglutide or liraglutide approved for T2D or obesity. Main Outcomes and Measures: Percentage weight change and categorical weight reduction of 10% or greater at 1 year. Results: A total of 3389 patients (mean [SD] age, 50.4 [12.2] years; 1835 [54.7%] female) were identified. Of these, 1341 patients received semaglutide for T2D; 1444, liraglutide for T2D; 227, liraglutide for obesity; and 377, semaglutide for obesity. Mean (SD) percentage weight change at 1 year was -5.1% (7.8%) with semaglutide vs -2.2% (6.4%) with liraglutide (P < .001); -3.2% (6.8%) for T2D as a treatment indication vs -5.9% (9.0%) for obesity (P < .001); and -5.5% (7.5%) with persistent medication coverage (ie, a cumulative gap of less than 90 days) at 1 year vs -2.8% (7.0%) with 90 to 275 medication coverage days and -1.8% (6.7%) with fewer than 90 medication coverage days (P < .001). In the multivariable model, semaglutide vs liraglutide (adjusted odds ratio [AOR], 2.19 [95% CI, 1.77-2.72]), obesity as a treatment indication vs T2D (AOR, 2.46 [95% CI, 1.83-3.30]), persistent medication coverage vs 90 medication coverage days (AOR, 3.36 [95% CI, 2.52-4.54]) or 90 to 275 medication coverage days within the first year (AOR, 1.50 [95% CI, 1.10-2.06]), high dosage of the medication vs low (AOR, 1.58 [95% CI, 1.11-2.25]), and female sex (AOR, 1.57 [95% CI, 1.27-1.94]) were associated with achieving a 10% or greater weight reduction at year 1. Conclusions and Relevance: In this retrospective cohort study of 3389 patients with obesity, weight reduction at 1 year was associated with the medication's active agent, its dosage, treatment indication, persistent medication coverage, and patient sex. Future research should focus on identifying the reasons for discontinuation of medication use and interventions aimed at improving long-term persistent coverage.

Use of glucagon-like-peptide 1 receptor agonist in the treatment of childhood obesity.

PURPOSE OF REVIEW: Pediatric obesity is a growing epidemic. Lifestyle modifications remain central to obesity treatment, however pharmacologic options have gained traction, particularly glucagon-like peptide-1 receptor agonists (GLP-1RA). This review aims to summarize evidence on the use of GLP-1RAs in the management of pediatric obesity, physiological mechanisms of action of GLP-1RAs and their role in appetite regulation and glucose homeostasis and address the challenges and special considerations surrounding GLP-1RA use. RECENT FINDINGS: Recent studies have highlighted the efficacy of GLP-1RAs, such as exenatide, liraglutide, and semaglutide, in promoting weight loss and improving metabolic parameters in children and adolescents. GLP-1RA's efficacy extends beyond glycemic control to include weight loss mechanisms such as delayed gastric emptying (gastroparesis), and appetite suppression. Semaglutide, the newest GLP-1RA, holds potential for substantial weight loss in adolescents and demonstrates a similar safety and efficacy as seen in adults. SUMMARY: GLP-1RAs may offer a promising adjunct therapy for pediatric obesity, particularly in cases where lifestyle interventions alone are insufficient. However, further research is needed to elucidate long-term safety and efficacy outcomes and to address potential disparities in access to care. Overall, this review highlights the relevance and timeliness of incorporating GLP-1RAs into the comprehensive management of pediatric obesity.

Effects of the glucagon-like peptide-1 receptor agonist dulaglutide on sexuality in healthy men: a randomised, double-blind, placebo-controlled crossover study.

BACKGROUND: The reward-regulatory properties of GLP-1 are attracting increasing interest. Animal studies show that GLP-1 receptor agonists not only reduce consumption of addictive substances, but also influence sexual behaviour. We aimed to investigate the effect of dulaglutide versus placebo on sexual desire in humans. METHODS: In this randomised, double-blind, placebo-controlled crossover trial, healthy eugonadal men of normal weight, aged 18-50 years with active and satisfactory sex lifes were (1:1) randomly allocated to dulaglutide or placebo for four weeks. We assessed sexual desire (Massachusetts General Hospital-Sexual Functioning Questionnaire [MGH-SFQ]), hormones of the hypothalamic-pituitary-gonadal axis (total testosterone, follicle-stimulating hormone [FSH], luteinizing hormone [LH]) and sperm parameters. Changes in these parameters were compared under dulaglutide versus placebo using paired t-tests. FINDINGS: 24 out of 26 randomised participants completed the study (13 participants randomised to dulaglutide first and 13 to placebo first). No change in the MGH-SFQ was observed after four weeks of dulaglutide versus placebo (estimated difference 0.58 [95% CI -0.83 to 2.00], p-value = 0.402). Hormones of the hypothalamic-pituitary-gonadal axis (estimated differences: total testosterone (nmol/l) 0.9 [95% CI -1.5 to 3.3], FSH (IU/l) -0.2 [95% CI -0.3 to 0.0] and LH (IU/l) -0.8 [95% CI -1.5 to 0.0]) as well as sperm parameters all remained in the normal range without significant differences between the treatments. No severe adverse events occurred. INTERPRETATION: In this study of healthy men, we found no evidence of negative impacts of a four-week treatment with the widely used GLP-1 receptor agonist dulaglutide on sexual desire, hypothalamic-pituitary-gonadal axis hormones or sperm parameters.

The impact of approved anti-obesity medications on osteoarthritis.

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.

Efficacy, adherence and persistence of various glucagon-like peptide-1 agonists: nationwide real-life data.

AIM: The management of type 2 diabetes mellitus has advanced in the last two decades since the introduction of glucagon-like peptide-1 receptor agonists (GLP-1RAs). However, multiple factors may interfere with achieving better glycaemic control. This study evaluated the differences between various GLP-1RAs in efficacy, adherence and persistence. MATERIALS AND METHODS: We conducted a retrospective cohort study using the electronic medical database from Clalit Health Services. Adults with type 2 diabetes mellitus who purchased any GLP-1RA between 2009 and 2021 were included. The Index Date was defined as the date of the first purchase of any GLP-1RA. We evaluated the adherence, persistence and glycaemic control after GLP-1RAs initiation. Baseline glycaemic and post-treatment glycaemic controls were analysed. RESULTS: In total, 70 654 patients were included. The mean age was 11.7 ± 60.4, and 51% were females. A significant reduction in glycated haemoglobin (HbA1c) was observed in all patients who received GLP-1RAs. However, the percentage of changes in the HbA1c was higher among weekly GLP-1RA than daily initiators (14.6% vs. 10.2%, p < 0.001). The proportion of subjects with any decrease in HbA1c was higher among the once-weekly compared with the daily dose (82.4% vs. 74.7%) and mainly patients initiated semaglutide or dulaglutide, with 16.0% and 14.7% reduction. The frequency of good adherence (the proportion of days covered ≥80%) was significantly higher among the weekly group odds ratio = 1.25 (95% confidence interval 1.21-1.28). Good adherence was reported in older age, female gender, Jewish ethnicity and high socio-economic status (p < 0.001). CONCLUSIONS: Weekly GLP-1RAs initiators were more adherent, persistent to therapy and achieved better glycaemic control. Epidemiological variables might play a role in achieving this goal.

Real-world safety profile of once-weekly semaglutide in people with type 2 diabetes: Analysis of pooled data from the SemaglUtide Real-world Evidence (SURE) programme.

AIM: To investigate, through post hoc analysis of nine studies from the SemaglUtide Real-world Evidence (SURE) programme, the safety of once-weekly (OW) semaglutide in adults with type 2 diabetes (T2D) and in subpopulations in routine clinical practice, complementing findings from the phase 3 randomized clinical trial (RCT) SUSTAIN programme. METHODS: The SURE studies had a duration of ~30 weeks and included adults with diagnosed T2D treated with OW semaglutide. Safety information, including hypoglycaemic events, were collected and analysed for the total study population and for patient subgroups based on baseline patient characteristics, baseline co-medication and prescriber specialty. RESULTS: Of the total 3505 patients, 24.3% reported adverse events (AEs), with most patients reporting non-serious (22.3%) and mild (17.1%) AEs. AEs mainly belonged to the gastrointestinal disorders system organ class (16.3% of patients). In total, 5.1% of patients reported AEs that led to treatment discontinuation, 0.5% reported serious adverse drug reactions and 0.2% had an AE with a fatal outcome, reported as unrelated to treatment. Overall, 1.1% and 0.1% of patients reported level 2 and 3 hypoglycaemic events, respectively. A higher rate of level 2 hypoglycaemia was observed in patients with baseline microvascular complications treated with insulin versus those on insulin without these complications. CONCLUSIONS: Safety data reported in the real-world SURE studies were generally consistent with observations in phase 3 OW semaglutide RCTs. No new safety concerns were identified, highlighting that OW semaglutide is well tolerated by adults with T2D and in subpopulations in routine clinical practice.

Association between Symptoms of Depression and Generalised Anxiety Disorder Evaluated through PHQ-9 and GAD-7 and Anti-Obesity Treatment in Polish Adult Women.

Obesity impacts mental health greatly. Psychological factors may influence the effectiveness of its treatment. This study aimed to compare symptoms of generalised anxiety disorder and depression among adult women across different weight categories. The study sample comprised 1105 adult women. The computer-assisted web interview (CAWI) utilising the seven-item Generalised Anxiety Disorders Scale (GAD-7) and the nine-item Patient Health Questionnaire (PHQ-9) was used. Both GAD-7 and PHQ-9 scores correlated positively with BMI (r = 0.121, p < 0.001 and r = 0.173, p < 0.001, respectively) and negatively with age (r = -0.106, p < 0.001 and r = -0.103, p < 0.001, respectively). Patients undergoing treatment with semaglutide scored lower for both anxiety symptoms (8.71 ± 6.16, p = 0.013) and depression symptoms (9.76 ± 6.37, p = 0.013). Women who underwent bariatric surgery screened less frequently for anxiety (8.03 ± 6.27, p = 0.002) but not for depression. An interdisciplinary approach involving mental health professionals within the therapeutic team can comprehensively address factors contributing to obesity development and treatment outcomes. Further investigation of semaglutide's use is needed due to the promising evidence suggesting a positive effect on decreasing the severity of depression and anxiety symptoms to assess the direct or indirect character of this influence.
