Impact of biosimilar strategies on cost savings and utilization trends of adalimumab products among United States health plans

By Stephen Kang, PharmD; Mark Shinmoto, PharmD; Elton Teng, PharmD; Jeffrey He, PharmD; Rachel K. Hudson, PharmD, MBA

Pharmaceutical costs continue to drive overall healthcare expenditures, with an estimated spend of over $800 billion in 2024 and $417B (52%) from biologics (specialty drugs) (Long, 2025, slide 16)1. By providing highly similar, yet less expensive, treatment options, biosimilars offer opportunities for mitigating the risk of increasing drug spend and providing greater access to life-saving medicines. However, some biosimilar strategies employed by commercial health plans may inhibit the utilization of biosimilars and result in a suboptimal net reduction in plan spend. But, with the right strategy it is possible to achieve an appropriate balance of clinical and cost considerations.

Recently, our 2024-2025 Managed Care Fellow, Stephen Kang, Pharm D and our clinical team completed a comprehensive analysis of adalimumab (Humira® and biosimilars) using data from three large U.S. health systems, each employing distinct biosimilar strategies. Findings show that thoughtful biosimilar strategies—leveraging distribution channels and the use of biosimilars—can significantly reduce PMPM spending without compromising care.
