Biogen's Strategic Crossroads: Leqembi, Pipeline Expansion, and the Path to Sustainable Growth#
Biogen Inc. (BIIB) is at a critical juncture, navigating a complex pharmaceutical landscape marked by both challenges and opportunities. The company's stock, currently priced at $140.04, reflects this uncertainty, trading near 12-year lows despite recent earnings beats, according to Monexa AI. Key to Biogen's future are strategic initiatives centered on Leqembi, pipeline expansion through collaborations, and efficiency improvements via the 'Fit for Growth' program.
Leqembi's EU Approval and Slow Market Uptake#
Leqembi, Biogen's Alzheimer's drug developed with Eisai, remains a central growth pillar. Despite EU regulatory approval, some analysts describe its commercial performance as disappointing, as noted by Seeking Alpha. This slow uptake stems from reimbursement challenges, logistical complexities in administration, and competition. On February 28, 2025, Reuters reported that the EU regulator is not updating its opinion on Eisai-Biogen's Alzheimer's drug, maintaining its previous recommendation for approval. However, the potential approval of a subcutaneous maintenance dosing option could offer a more convenient administration method, boosting its market presence.
Leqembi's Impact on Alzheimer's Treatment#
The Alzheimer's therapeutics market is poised for substantial growth. Future Market Insights projects an expansion from $4.28 billion in 2025 to $10.43 billion by 2035. However, competition is intensifying, with Eli Lilly's Donanemab emerging as a significant contender. Some analysts, as cited by Patsnap Synapse, believe Donanemab could surpass Leqembi's market share due to more convenient dosing. Eisai remains optimistic, projecting Leqembi sales to increase to approximately $364 million by March 2025, according to Seeking Alpha.

Biogen and Stoke Therapeutics Partner on Dravet Syndrome Treatment#
Biogen's collaboration with Stoke Therapeutics (STOK) for Zorevunersen to treat Dravet Syndrome marks a strategic expansion into the rare disease market. On February 18, 2025, GlobeNewswire and BusinessWire announced the collaboration, highlighting Biogen's $165 million upfront payment and potential milestone payments of up to $385 million. Zorevunersen, targeting the SCN1A gene, aims to address the underlying genetic cause of Dravet Syndrome. This partnership broadens Biogen's pipeline and leverages its expertise in commercializing disease-modifying medicines. The Phase 3 EMPEROR study is set to begin in Q2 2025, with results expected in 2H 2027.
Zorevunersen: A Potential Breakthrough for Dravet Syndrome?#
The Dravet Syndrome market is projected to reach $1.95 billion by 2037, growing at a CAGR of 9.1%, according to Research Nester. The collaboration allows Stoke to retain rights in the US, Canada, and Mexico, while Biogen gains exclusive rights elsewhere. Success hinges on Zorevunersen's clinical trial outcomes and regulatory approvals.
Analysts Divided on Biogen's Future Growth Prospects#
Analyst sentiment on Biogen is mixed. While Q4 earnings surpassed expectations, analysts have lowered forecasts due to disappointing 2025 EPS guidance, Benzinga reports. Some analysts believe Leqembi and Skyclarys will drive future growth, while others express concerns about Leqembi's performance and declining MS franchise revenue. This divergence highlights the challenges Biogen faces in executing its strategic plan.
Revenue, Earnings, and Guidance#
Biogen's Q4 2024 earnings showed slight revenue growth, but Wall Street remains unimpressed due to weak guidance and declining key drug franchises, according to Seeking Alpha. Leqembi's commercial performance is disappointing, mirroring Aduhelm's failure, and Biogen's pipeline lacks promising products to drive future growth. The multiple sclerosis franchise is in decline, and new drug approvals like Qalsody and Skyclarys have shown minimal revenue impact.
MS Franchise Decline: A Cause for Concern?#
Biogen's multiple sclerosis (MS) franchise faces increasing competition and patent expirations. Drugs like Tecfidera and Avonex have lost patent protection, intensifying competition from generics and biosimilars. This puts pressure on Biogen's MS revenue, necessitating strategies to mitigate this decline, including developing new MS therapies and focusing on patient retention.
MS Market Dynamics: Competition and Patent Expirations#
To maintain its position in the MS market, Biogen must adapt to evolving market dynamics and increasing competition. The company is focusing on new therapies and patient retention strategies to offset revenue decline.
BIIB Stock: Value Play or Value Trap?#
Biogen's stock has steadily declined since its 2021 peak, trading near 12-year lows. MarketBeat suggests the stock may be a value play, with a P/E ratio less than half the industry average. However, risks such as Leqembi's performance and MS franchise decline must be considered before deeming it a value investment.
Biogen's 'Fit for Growth' Program: Details and Impact#
Biogen's 'Fit for Growth' program aims to improve efficiency and reduce costs through streamlined operations, prioritized R&D investments, and optimized organizational structure. This initiative seeks to enable Biogen to invest in key growth drivers while improving profitability. The program's impact on R&D spending and pipeline prioritization remains to be seen.
Cost-Cutting Measures and R&D Prioritization#
The 'Fit for Growth' program is expected to streamline operations and prioritize R&D investments, potentially impacting Biogen's pipeline and future product development.
The Competitive Landscape: Key Players and Challenges#
Biogen operates in a competitive landscape, facing rivals like Eli Lilly in Alzheimer's and Novartis and Roche in multiple sclerosis. Success requires continuous innovation, new therapy development, and effective product commercialization.
Eli Lilly's Donanemab: A Major Competitor#
Eli Lilly's Donanemab poses a significant competitive threat to Leqembi in the Alzheimer's market. If approved, Donanemab's more convenient dosing could lead to greater market share.
Biogen's Pipeline: Promising Therapies in Development#
Biogen has a diverse pipeline targeting neurological and neurodegenerative diseases, including Leqembi for Alzheimer's and Zorevunersen for Dravet Syndrome. Pipeline success is crucial for offsetting revenue decline from legacy products.
Neurology and Neurodegenerative Diseases#
Biogen's pipeline focuses on neurological and neurodegenerative diseases, with potential treatments for multiple sclerosis, Parkinson's disease, and other neurological disorders.
Regulatory Landscape: Key Approvals and Hurdles#
Regulatory decisions significantly impact Biogen's products. While Leqembi has received approvals, reimbursement and market access remain challenges. Effective navigation of the FDA and EMA approval processes is critical.
FDA and EMA Approval Processes#
Biogen must effectively navigate the FDA and EMA approval processes to bring its products to market and ensure their commercial success.
Conclusion: Biogen's Path Forward#
Biogen faces a complex path forward, balancing challenges in its MS franchise with opportunities in Alzheimer's treatment and rare diseases. Leqembi's market uptake, strategic collaborations, and the 'Fit for Growth' program will be critical in shaping the company's future and influencing investment decisions.
