Core Viewpoint - Eli Lilly's obesity pill, orforglipron, has shown disappointing trial results compared to expectations, leading to a significant drop in stock price, although it has since recovered somewhat [2][3]. Drug Efficacy and Comparison - In a late-stage trial, orforglipron resulted in less weight loss (12.4% at the highest dose) and higher side effects than anticipated, while Novo Nordisk's oral semaglutide showed greater efficacy (up to 16.6% weight loss) [13][14]. - Analysts believe that orforglipron could still be a viable competitor in the weight loss market, especially due to its easier absorption and manufacturing advantages over Novo Nordisk's peptide-based drug [5][6]. Market Potential and Projections - Goldman Sachs analysts project that daily oral weight loss pills could capture 24% of the $95 billion global weight loss drug market by 2030, with Eli Lilly's orforglipron expected to hold a 60% share of the daily oral segment, translating to approximately $13.6 billion [7][8]. Manufacturing and Pricing Considerations - Eli Lilly's orforglipron is a small-molecule drug, making it easier and potentially cheaper to manufacture compared to Novo Nordisk's oral semaglutide, which is a peptide medication [5][22]. - Pricing strategies for both drugs remain uncertain, but analysts suggest that orforglipron could be priced lower than Novo Nordisk's offering, which may provide a competitive edge in a market where many health plans do not cover obesity treatments [6][23]. Side Effects and Tolerability - The side effects of orforglipron, primarily gastrointestinal, led to a 10.3% discontinuation rate at the highest dose, which is higher than the placebo group [17][19]. - Comparatively, Novo Nordisk's oral semaglutide had a higher incidence of gastrointestinal side effects, with 30.9% reporting vomiting and 46.6% reporting nausea [19]. Competitive Landscape - The obesity drug market is competitive, with other companies like Pfizer and Viking Therapeutics also developing oral medications, but Eli Lilly and Novo Nordisk are currently leading the race [9][27]. - Viking Therapeutics recently reported disappointing trial results, indicating that its drug may not be as effective as Eli Lilly's orforglipron [27][28].
