Clinical Trial Results - In the REDEFINE 1 trial, CagriSema demonstrated a weight loss of -22.7% in non-diabetic obese patients, with 34.7% of participants losing ≥25% of their body weight [4]. - In the REDEFINE 2 trial, diabetic obese patients treated with CagriSema achieved a weight loss of -15.7%, with 22.9% losing ≥20% [4]. Preclinical Findings - The combination of BGM0504 and BGM1812 showed superior weight loss effects in diet-induced obesity models, indicating the potential for further development of GLP-1/GIP RA and Amylin combination therapies [6].

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]

Core Viewpoint - Semaglutide, developed by Novo Nordisk, is a GLP-1 receptor agonist that suppresses appetite and reduces caloric intake, approved for treating type 2 diabetes and weight loss. Its emergence has disrupted the weight loss drug market, with sales exceeding $7.8 billion in Q1 this year. However, Eli Lilly's Tizepatide has surpassed Semaglutide's weight loss records, achieving an average weight reduction of 20.2% in a head-to-head clinical trial [2][3]. Group 1: Sales and Market Impact - Tizepatide's sales in Q1 have already exceeded $6.1 billion, narrowing the gap with Semaglutide [3]. - The clinical trial results published in NEJM indicate that Tizepatide outperforms Semaglutide in weight loss effectiveness [2][3]. Group 2: Clinical Trials and Results - The REDEFINE 1 trial showed that the combination of Cagrilintide and Semaglutide resulted in an average weight loss of 20.4% over 68 weeks among non-diabetic overweight/obese participants, with 34.7% losing ≥25% of their body weight [11][13]. - In the REDEFINE 2 trial, the same combination led to a 13.7% average weight loss in overweight/obese participants with type 2 diabetes, significantly higher than the placebo group [17][19]. Group 3: Health Benefits and Safety - Cagrilintide and Semaglutide combination therapy showed improvements in various health metrics, including a 9.9 mmHg reduction in systolic blood pressure compared to 3.2 mmHg in the placebo group [13]. - The incidence of gastrointestinal adverse events was higher in the combination therapy group (79.6%) compared to the placebo group (39.9%), but most events were transient and mild to moderate in severity [14][20].
