Biosimilars Immunology Roundup for May 2023—Podcast Edition

Patients with rheumatoid arthritis (RA) who switched from Enbrel (reference etanercept) to a biosimilar maintained remission, even after their dose was reduced, with no signs of worsening based on clinical scores, ultrasound scans, or lab tests, according to a new study.

To close out the Festival of Biologics, Craig Burton and Giuseppe Randazzo from the Association for Accessible Medicines and the Biosimilars Council tackle the current biosimilar landscape and how the industry can emerge from the "biosimilar void."

A wave of biosimilar approvals, aggressive pricing strategies, and a regulatory sea change are setting the stage for unprecedented momentum in the US biologics market, with 2025 already proving to be a landmark year in reshaping cost, access, and innovation across therapeutic areas.

Despite saving billions, biosimilars still account for only a small share of the biologics market—what's standing in the way of broader adoption and how can artificial intelligence (AI) help change that?

Sandoz's antitrust suit against Amgen, the FDA’s interchangeability designation for Celltrion’s adalimumab biosimilar, and the inclusion of an ustekinumab biosimilar in Costco’s prescription program highlight growing momentum to expand biosimilar access and affordability for patients with chronic inflammatory diseases.

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).
