Detailed Narrative
2024 Performance Highlights
Amgen achieved strong execution in 2024, with total revenues growing 19% to $33.4 billion, driven by 23% volume growth. The company exited the year with 14 products annualizing over $1 billion and 21 products delivering record sales, demonstrating broad portfolio strength and commercial success across therapeutic areas and geographies. Non-GAAP operating margin was 47% for the full year, and the company generated $10.4 billion in free cash flow.
Strategic Pipeline Investments
The company is making significant R&D investments, increasing non-GAAP R&D spend by 25% to $5.9 billion in 2024, primarily in late-stage assets like MariTide, rocatinlimab, bemarituzumab, and IMDELLTRA. This strategic focus aims to unlock future growth opportunities and leverage innovation, including artificial intelligence, across the value chain, from molecule design to commercial operations. Non-GAAP R&D expense is projected to grow mid-teens in 2025.
MariTide Development
MariTide, a novel obesity therapy, is advancing with Phase III studies expected to initiate in H1 2025. Key Phase II data readouts are anticipated in H2 2025 for type 2 diabetes and chronic weight management, with full Phase II Part 1 data to be presented at the ADA meeting in June. The therapy is highlighted for its ability to deliver consistent, predictable, and sustained weight loss through 52 weeks without a plateau, convenient monthly dosing, and clinically meaningful improvements in cardiometabolic parameters.
Cardiovascular Portfolio Expansion
Repatha continues strong growth, with sales up 36% to over $2.2 billion in 2024, driven by volume and improved access, particularly in the U.S. primary care setting. The VESALIUS Phase III primary prevention study for Repatha is expected to read out in H2 2025, aiming to demonstrate reduced risk of a first cardiovascular event. Olpasiran, an Lp(a)-targeting siRNA, is progressing with the fully enrolled OCEAN(a) Phase III trial and plans for an additional Phase III study in primary prevention in late 2025/H1 2026.
Oncology and Rare Disease Advancements
The innovative oncology portfolio contributed almost $8 billion in sales, with BLINCYTO growing 41% to over $1.2 billion and IMDELLTRA generating $115 million in 7 months post-launch for small cell lung cancer. In rare diseases, UPLIZNA has a PDUFA date of April 3, 2025, for IgG4-related disease and anticipates 52-week data for generalized Myasthenia Gravis later this year. TEPEZZA is expanding internationally with a Japan launch and 7 additional countries expected in 2025, despite a projected lower Q1 2025 due to seasonal patterns.
Biosimilar Strategy and Performance
Amgen's biosimilar portfolio grew 16% to $2.2 billion in 2024, with a 100% success rate of FDA approval once entering the clinic. The successful launch of PAVBLU (EYLEA biosimilar) in Q4 2024, generating $31 million in 9 weeks, highlights the company's strategy to be an early entrant with high-quality, easy-to-use products like the prefilled syringe. Upcoming launches include WEZLANA (STELARA biosimilar) in Q1 2025 and BEKEMV (SOLIRIS biosimilar) in Q2 2025, anticipating robust growth and attractive returns.
