Core Viewpoint - Amgen is set to present complete Phase II clinical data for its next-generation weight loss drug MariTide at the American Diabetes Association (ADA) annual meeting on June 23, 2025, which is expected to be a significant catalyst for the company's stock price and the weight loss drug sector overall [1][2]. Group 1: Clinical Data and Efficacy - The Phase II trial for MariTide targets overweight or obese patients without type 2 diabetes and lasts for 52 weeks, with topline data expected to cover most key metrics [1]. - Goldman Sachs anticipates that the complete data release will provide additional insights not included in the previously released summary data, enhancing understanding of MariTide's clinical characteristics [1][3]. - Initial reports indicate that MariTide achieved nearly a 20% average weight reduction over 52 weeks, surpassing current leading weight loss therapies [4][6]. Group 2: Safety and Tolerability - Concerns regarding gastrointestinal adverse events were noted, particularly in the early stages of the trial, but these events were primarily mild and decreased significantly with dose escalation [6]. - The improvement in gastrointestinal tolerability is viewed positively for MariTide's future clinical acceptance [6]. Group 3: Market Positioning and Future Prospects - Goldman Sachs believes MariTide's lower dosing frequency and milder side effects could position it uniquely in the obesity treatment market, especially in primary care settings [3]. - The company has initiated a Phase III clinical program for MariTide, focusing on obesity-related complications, including cardiovascular outcomes [3][7]. - Future data from the maintenance phase of the Phase II trial, expected in the second half of 2025, will clarify the drug's long-term efficacy and safety [7]. Group 4: Competitive Landscape - Goldman Sachs is closely monitoring other significant obesity-related research data, including results from Eli Lilly and Novo Nordisk's trials, which are expected to be released around the same time as MariTide's data [9][11].
