整理 | GLP1减重宝典内容团队 GIP(胃抑制多肽)是一种由肠道K细胞分泌的多肽类激素,与GLP-1(胰高血糖素样肽-1)一起被称为肠促胰素。肠促胰素通过刺激胰岛素分 泌,帮助清除大约80%饮食中吸收的葡萄糖。对于2型糖尿病(T2D)患者来说,肠促胰素的功能几乎完全丧失,因此恢复这一功能对糖尿病治 疗至关重要。近期的研究表明,GIP在肠促胰素中扮演着最重要的角色。口服葡萄糖后,约44%的胰岛素分泌是由GIP刺激产生的,而GLP-1仅 占22%。 替尔泊肽是一种基于GIP序列改造的多肽,是目前研究进展最快的GLP-1/GIP双受体激动剂,也是GIP受体激动剂中的领军药物。通过对GIP进 行C20不饱和脂肪酸侧链修饰,替尔泊肽的半衰期可达到5天,支持每周一次的给药频率。 在受体亲和力方面,替尔泊肽主要偏向于GIP受体 ,其GIP受体的效价与天然GIP相当,而对GLP-1受体的效价比天然GLP-1低约13倍。临床试验表明,替尔泊肽在控制血糖和减轻体重方面优于 GLP-1单一受体激动剂——司美格鲁肽。近期研究发现,降低起始剂量和增加剂量的幅度可以有效减少替尔泊肽的副作用,而胃排空速率对餐 后血糖的影响也被证明是重 ...

整理 | GLP1减重宝典内容团队 随着全球肥胖症和2型糖尿病(T2DM)发病率持续攀升,开发新型高效的治疗药物成为医学研究的重要方向。GLP-1/GIP双受体激动 剂通过同时激活胰高糖素样肽-1(GLP-1)和葡萄糖依赖性促胰岛素释放多肽(GIP)受体,实现控糖和减重的双重效果,在提高治疗 效率的同时降低剂量相关的不良反应。目前,已有十余种此类药物进入临床阶段,仅有一款正式上市,HRS9531的研发进度在全球位 列第二。 在第85届美国糖尿病协会年会(ADA 2025)上,恒瑞医药自主研发的GLP-1/GIP双受体激动剂HRS9531公布了三项最新研究成果:两 项评估注射剂型在超重或肥胖人群中的疗效与安全性,一项探讨口服制剂在健康人群中的药效、代谢动力学及耐受性。本文对这三项研 究内容进行梳理和总结,展示中国在该领域的最新进展。 研究一:HRS9531注射液在中国超重/肥胖人群中的疗效与安全性(Ⅱ期) 研究目的 本项Ⅱ期临床研究旨在评估HRS9531每周一次皮下注射在未合并糖尿病的中国超重或肥胖成人中的体重管理效果及安全性。 安全性 不 良 事 件 发 生 率 为 HRS9531 组 91.8% , 安 慰 ...

Core Viewpoint - Semaglutide, developed by Novo Nordisk, has significantly impacted the weight loss market with over $7.8 billion in global sales in Q1 this year, approved for treating type 2 diabetes and obesity [2] - Tirzepatide, developed by Eli Lilly, is rapidly gaining ground, showing superior weight loss results compared to Semaglutide in recent studies [4][5] Group 1: Clinical Trial Results - In the SURMOUNT-5 trial, Tirzepatide led to an average weight loss of 20.2% (approximately 22.8 kg) over 72 weeks, with 31.6% of participants losing 25% or more of their body weight [5] - The REDEFINE 1 trial showed that the combination of Cagrilintide and Semaglutide (CagriSema) resulted in an average weight loss of 20.4% (approximately 26.6 kg) over 68 weeks, outperforming both Semaglutide and Cagrilintide alone [8] - In the REDEFINE 2 trial, CagriSema achieved an average weight loss of 13.7% in type 2 diabetes patients, significantly higher than the 3.4% in the placebo group [10][13] Group 2: Safety and Side Effects - CagriSema treatment was associated with a higher incidence of gastrointestinal adverse events (79.6%) compared to the placebo group (39.9%), though most symptoms were mild to moderate [8][13] - In the REDEFINE 2 trial, 72.5% of CagriSema participants reported gastrointestinal side effects, again higher than the 34.4% in the placebo group [13] Group 3: Market Outlook - The combination of Semaglutide and Cagrilintide shows potential to become a significant player in the obesity treatment market, alongside Semaglutide and Tirzepatide [14] - The results from recent clinical trials suggest that CagriSema may redefine the competitive landscape of weight loss medications, particularly in both diabetic and non-diabetic populations [14]
