Core Viewpoint - The development of Alzheimer's drugs is facing significant bottlenecks, with Biogen and Eli Lilly maintaining a leading position in the market. However, due to research setbacks, safety risks, and slow adoption, the market size forecast for 2030 has been drastically reduced to $6 billion from a previous expectation of $13 billion [3][4]. Group 1: Market Forecast and Sales Predictions - The combined sales of Biogen's Leqembi and Eli Lilly's Kisunla are projected to reach $5.91 billion by 2025, with potential growth to $40 billion by 2030, which is 24% lower than the market's general expectation of $50 billion due to slow drug adoption [4]. - By 2030, the total sales of Alzheimer's drugs are expected to reach $6 billion, with nearly $1 billion coming from new mechanism drugs [5]. Group 2: Impact of Research Failures - A series of late-stage clinical trial failures have led to a 54% reduction in sales forecasts for Alzheimer's drugs since June 2024, with risk-adjusted sales expectations shrinking by over $7 billion for 2025-2030, including a $3 billion reduction for 2030 alone [8][11]. - The decline in sales expectations is attributed to the exit of several late-stage candidates from the market due to research failures or lowered priorities [8]. Group 3: Competitive Landscape - The long-term administration of Leqembi shows limited cognitive improvement, particularly in patients with low or no tau pathology, which affects about 40% of the trial population. This has led to skepticism among physicians and patients regarding the drug's efficacy [11]. - New candidates, such as Novo Nordisk's semaglutide and Roche's trontinemab, are expected to increase competitive pressure, potentially limiting the market share of first-generation amyloid-beta antibodies [11][15]. Group 4: Company-Specific Insights - Biogen's Leqembi faces increasing risks due to limited application, with sales forecasts for 2030 being 20% lower than market expectations, driven by safety concerns and access barriers [13]. - Eli Lilly is expected to surpass Biogen in sales by 2029, driven by the approval of Kisunla and subsequent antibody drugs, indicating a shift in market leadership [15].
