Infographic: The 7 FDA-Approved Biosimilars

During Q1 2025, pharmaceutical companies accelerated biosimilar expansion through strategic acquisitions and partnerships in hopes of boosting patient access to lower-cost treatments in immunology and oncology.

On this episode of Not So Different, we discuss market changes in the adalimumab space; calls for PBM transparency and biosimilar access reforms grew; new data for biosimilars in gastroenterology conditions; and all the takeaways from this year's Global Biosimilars Week.

High adherence rates, comparable clinical effectiveness, and cost savings have marked the early adoption of adalimumab biosimilars in the US, particularly in formulary-driven transitions, as shown in 2 retrospective studies presented at the Academy of Managed Care Pharmacy annual meeting (AMCP 2025).

On this episode of Not So Different, we review biosimilar news coming out of June, with clinical trial results from conferences and a study showcasing how to overcome economic and noneconomic barriers to oncology biosimilars.

As the biosimilar industry celebrates a decade of growth, the market continues to evolve with expanded treatment options, cost savings, and a flurry of new competitors—yet regulatory challenges, market dynamics, and patient accessibility remain key hurdles to unlocking its full potential.

People with inflammatory bowel disease (IBD) who switched to the infliximab biosimilar CT-P13 had higher treatment persistence (84% and 91%) than those new to infliximab (66% and 53%), with no new safety concerns.
