U.S. Pharmaceutical Market By Molecule Type Insights

Biologics & Biosimilars dominated the U.S. pharmaceutical market in 2024, thanks to a surge in monoclonal antibody approvals and high demand for biologics in treating cancer and autoimmune diseases. Biologics are not only more effective in targeting complex molecular pathways but also tend to command premium prices. AbbVie's Humira and Merck’s Keytruda are prime examples of blockbuster biologics that have reshaped therapeutic strategies and revenue models. The increasing availability of biosimilars is driving market competition while making biologics more accessible.

Within this segment, Cell & Gene Therapy is experiencing the fastest growth. The FDA approved over 20 gene and cell therapies in 2023, marking a new era of regenerative medicine. These therapies offer potentially curative outcomes for diseases previously considered untreatable, such as spinal muscular atrophy and inherited retinal disorders. Companies like Novartis and bluebird bio are expanding their pipelines aggressively, and new startups are gaining VC interest at a rapid pace.

U.S. Pharmaceutical Market By Product Insights

Branded drugs account for the largest share of the U.S. pharmaceutical market due to their continued dominance in specialized therapy areas like oncology, immunology, and rare diseases. These products command high prices and generate substantial revenue during their exclusivity period. Pfizer, Johnson & Johnson, and Merck continue to rely heavily on their branded portfolios to maintain leadership.

On the other hand, generics are witnessing renewed growth, particularly after the expiration of patents for several high-revenue drugs like Revlimid and Tecfidera. Generic manufacturers like Teva, Mylan, and Sandoz are capitalizing on these openings while improving manufacturing technologies and compliance systems. Government incentives to reduce healthcare costs have also made generics a favorable option for Medicaid and Medicare programs.
