Core Insights - The SURMOUNT-5 study results indicate that tirzepatide demonstrates superior efficacy in weight loss compared to semaglutide, achieving significant weight reduction in participants [1][2] Group 1: Study Results - Tirzepatide achieved a relative weight loss of 1.47 times compared to semaglutide, with an average weight reduction of 20.2% versus 13.7% for semaglutide at week 72 [1] - Participants in the tirzepatide group lost an average of 22.8 kg, while those in the semaglutide group lost an average of 15.0 kg [1] - In key secondary endpoints, 64.6% of participants in the tirzepatide group achieved a weight loss of ≥15%, compared to 40.1% in the semaglutide group [2] Group 2: Safety and Tolerability - The overall safety profile of tirzepatide was consistent with previous SURMOUNT studies, with the most common adverse events being mild to moderate gastrointestinal issues [2] - The proportion of participants who discontinued treatment due to adverse events was 6.1% for tirzepatide and 8% for semaglutide, although the study could not directly compare safety and tolerability between the two drugs [2] Group 3: Market Context - Semaglutide is currently a leading GLP-1 receptor agonist, with combined sales of approximately 84 billion USD in the first quarter of this year [3] - Tirzepatide, approved as the first GIP/GLP-1 receptor agonist in China, achieved sales of 6.15 billion USD in the first quarter, showing significant year-over-year growth [3]

5月12日，礼来公布SURMOUNT-5研究的详细结果。该研究是一项开放标签3b期临床试验，旨在评估在 肥胖或伴有至少一种合并症(如高血压、血脂异常、阻塞性睡眠呼吸暂停、心血管疾病)的超重成人(且不 合并糖尿病)，GLP/GLP-1双受体激动剂替尔泊肽(tirzepatide)与GLP-1单受体激动剂司美格鲁肽 (semaglutide)的有效性与安全性。在第72周时，替尔泊肽达到主要终点和所有五个关键次要终点，且在 整个试验中显示出相较司美格鲁肽的优越性。(智通财经) ...
