Healthy Returns: New weight loss drug data show Eli Lilly is gaining ground

Core Insights - The competition in the weight loss drug market is intensifying, with companies presenting new data on treatments at the American Diabetes Association conference, indicating a potential market value exceeding $150 billion annually by the end of the decade [2][3]. Eli Lilly - Eli Lilly's experimental pill, orforglipron, demonstrated a 7.6% weight loss in Type 2 diabetes patients over 40 weeks without serious side effects, with plans to launch the pill next year [3][4]. - The company is also developing bimagrumab, which aims to preserve lean muscle mass while enhancing fat loss in patients using existing treatments like Wegovy [4][5]. - Another experimental drug, eloralintide, showed promise in weight loss with minimal side effects, mimicking the hormone amylin to promote satiety [6]. Novo Nordisk - Novo Nordisk is working to catch up with Eli Lilly, having released full results from late-stage trials of its weekly injection, CagriSema, which showed significant weight loss despite initial concerns about efficacy [7][10]. - CagriSema combines cagrilintide and semaglutide, maintaining a safety profile similar to Wegovy while delivering more weight loss [10][11]. - The company is also advancing amycretin, which helped patients lose up to 24.3% of their weight after 36 weeks, with plans for both injectable and oral versions [11]. Amgen - Amgen is strategizing to enter the weight loss market with its experimental drug MariTide, which has shown significant weight loss but also high side effect rates in trials [12][13]. - The company is implementing a lower starting dose and gradual dose escalation strategy to improve patient tolerance and reduce side effects [14][15]. - Analysts believe that Amgen's approach may yield better-than-expected phase three trial results, potentially enhancing efficacy if patients remain on the drug [18].
