Core Viewpoint - Obesity is a complex disease that significantly contributes to metabolic disorders and poses a heavy burden on healthcare systems. Current interventions have limited long-term efficacy, highlighting the need for a deeper understanding of the mechanisms behind obesity development [2]. Group 1: Mechanisms of Obesity - The primary cause of obesity is energy imbalance, where energy intake exceeds energy expenditure over time. The energy homeostasis is regulated by the brain-peripheral organ interaction, particularly through the gut-brain axis and the fat-brain axis [2]. - Research on the gut-brain axis has made significant progress, especially in targeting incretin pathways, while the core mechanisms of the fat-brain axis remain to be fully understood [2]. Group 2: Leptin Resistance - Leptin, a key feedback signal from adipose tissue, regulates energy balance by inhibiting food intake and promoting energy expenditure. However, obesity often leads to leptin resistance, disrupting the communication between adipose tissue and the brain [3][4]. - A recent study published in Cell Metabolism reveals a new mechanism driving central leptin resistance, identifying extracellular vesicles (EVs) derived from adipose tissue as crucial regulators of central leptin sensitivity [4][10]. Group 3: Role of Extracellular Vesicles - The study demonstrates that inhibiting adipose EV production in animal models leads to significant weight gain and increased body fat due to increased food intake and decreased energy expenditure [5]. - Only EVs from healthy mice effectively reduced weight and improved energy imbalance in obese mice, indicating the importance of healthy adipose EVs in maintaining energy homeostasis [5][6]. Group 4: Mechanisms of Action - The weight loss effect of adipose EVs relies on an intact leptin signaling pathway, as they do not induce weight loss in leptin-deficient mice [6]. - Adipose EVs can cross the blood-brain barrier and specifically target neurons expressing leptin receptors, enhancing central leptin sensitivity and maintaining energy balance [6][8]. Group 5: miRNA and Targeting Mechanisms - miRNA within adipose EVs are identified as key components mediating the effects on central leptin sensitivity. The study categorizes miRNAs into leptin-sensitizing and leptin-desensitizing types, with the former being crucial for preventing central leptin resistance [7][10]. - The research also identifies specific membrane proteins on adipose EVs that facilitate brain targeting, leading to the development of engineered EVs for delivering leptin-sensitizing miRNAs to the brain [8][10]. Group 6: Implications for Treatment - This research shifts the paradigm of leptin resistance from a central brain-focused approach to an inter-organ communication framework, opening new avenues for innovative obesity therapies targeting the fat-brain axis [10][11].

Core Insights - Obesity is a global epidemic closely linked to insulin resistance and various serious metabolic complications. GLP-1 receptor agonists, particularly the dual-action GLP-1/GIP agonist Tirzepatide, have significantly advanced obesity treatment, but they have limitations such as potential muscle loss and dependence on sustained weight loss for improving insulin sensitivity [6][13]. Treatment Innovations - Azemiglitazone Potassium (0602K) is a new generation insulin sensitizer optimized to avoid the side effects associated with traditional insulin sensitizers that activate metabolic nuclear receptor PPARγ directly. Research suggests that combining 0602K with Tirzepatide could enhance metabolic improvement by acting on both muscle and fat tissues [7][13]. Research Findings - During the 2025 ObesityWeek, Dr. Jerry Colca from Cirius Therapeutics presented findings on the synergistic effects of 0602K and Tirzepatide. In a study using a diet-induced obesity model with C57BL/6J mice, the combination treatment maintained weight loss achieved by Tirzepatide alone and significantly promoted the remodeling of subcutaneous and visceral fat structures while preserving skeletal muscle function [9][11]. Mechanism of Action - The combination therapy was shown to enhance UCP1 expression, effectively increasing the activity of thermogenic pathways in subcutaneous fat. Notably, 0602K alone increased muscle mass, and when combined with Tirzepatide, it altered the muscle transcriptome, significantly upregulating key structural and functional proteins such as myosin and troponin, indicating protective remodeling of skeletal muscle [11][13]. Future Implications - Overall, the experimental data reveal a surprising synergistic effect between 0602K and Tirzepatide, suggesting that combining MPC inhibitors with GLP-1/GIP agonists could promote beneficial remodeling of adipose tissue and mitigate muscle loss associated with monotherapy. This combination may further expand the application prospects in weight management treatments [13].

Core Viewpoint - The STEP UP study demonstrates that the 7.2mg dose of semaglutide significantly improves weight loss and metabolic health in obese patients compared to lower doses and placebo, providing a new treatment option for those who did not achieve desired results with lower doses [5][12]. STEP UP Study Overview - The STEP UP study is a phase 3b, randomized, double-blind, placebo-controlled clinical trial involving 1,407 obese adults (BMI ≥ 30 kg/m²) without diabetes, assessing the efficacy and safety of different doses of semaglutide [6]. - Participants were randomly assigned to three groups: 7.2mg semaglutide (1,005 participants), 2.4mg semaglutide (201 participants), and placebo (201 participants), with a treatment duration of 72 weeks followed by a 9-week follow-up [6]. Primary and Secondary Endpoints - The primary endpoint was the percentage change in body weight from baseline to week 72 comparing 7.2mg semaglutide to placebo, along with the proportion of participants achieving a weight loss of ≥5% [7]. - Secondary endpoints included comparisons of weight percentage changes, waist circumference changes, and proportions of participants achieving weight loss of ≥10%, 15%, 20%, and 25% between the 7.2mg and 2.4mg groups [7]. Results: Significant Weight Loss and Waist Circumference Reduction - The 7.2mg semaglutide group achieved an average weight loss of 18.7%, compared to 3.9% in the placebo group, with an estimated treatment difference (ETD) of -14.8% (p<0.0001) [8]. - Compared to the 2.4mg group, the 7.2mg group also showed greater weight loss (18.7% vs. 15.6%, ETD -3.1%, p<0.0001) [8]. - The proportion of participants losing ≥5% of body weight was significantly higher in the 7.2mg group (90.7%) compared to the placebo group (36.8%) [10]. Weight Loss Proportions - Weight loss ≥10%: 7.2mg group 82.4%, 2.4mg group 75.1%, placebo group 20.5% [10] - Weight loss ≥15%: 7.2mg group 66.5%, 2.4mg group 54.5%, placebo group 7.6% [10] - Weight loss ≥20%: 7.2mg group 47.7%, 2.4mg group 33.3%, placebo group 2.9% [10] - Weight loss ≥25%: 7.2mg group 31.2%, 2.4mg group 15.3%, placebo group 0% [10] Significant Improvement in Metabolic Indicators - The 7.2mg group showed significant improvements in waist circumference, blood pressure, blood lipids, HbA1c, and fasting blood glucose [11]. - Average waist circumference reduction was 17.5cm in the 7.2mg group compared to 5.9cm in the placebo group (ETD -11.7cm, p<0.0001) [11]. - HbA1c decreased by 0.32 percentage points in the 7.2mg group versus 0.02 in the placebo group, and fasting blood glucose decreased by 0.63mmol/L compared to 0.12mmol/L in the placebo group [11]. Conclusion - The STEP UP study results indicate that the 7.2mg semaglutide formulation shows significantly better efficacy and good safety in obesity treatment, offering new options for patients who did not meet treatment goals with lower doses [12].
