An Overview of Adalimumab Biosimilars

This is a video synopsis/summary of a panel discussion involving Jamie T. Brogan, MSN, APRN, FNP-BC; Kostas Botsoglou, MD; Jordan Axelrad, MD, MPH; Sophia Humphreys, PharmD, MHA; and Peter Lio, MD.

The discussion focuses on adalimumab biosimilars, examining their indications, mechanism of action, interchangeability, and clinical implications. Currently, there are over 40 biosimilars created for a dozen biologic products, with a focus on adalimumab. While most indications of adalimumab have biosimilar alternatives, three orphan drug indications remain unapproved for biosimilars.

The mechanism of action for adalimumab biosimilars mirrors that of the reference product, with rigorous FDA review processes ensuring structural and functional similarity. Biosimilars must demonstrate identical primary and secondary structures to reference products, differing only in tertiary and quaternary folding. Additionally, they share the same administration route and strength.

Interchangeability designation by the FDA streamlines pharmacy-level switches, but specific conditions must be met. Biosimilars must replicate clinical outcomes, maintain safety profiles, and undergo switching studies. Despite potential benefits, providers emphasize the importance of patient education and notification regarding biosimilar switches to maintain therapy continuity.

The discussion highlights the need for proactive patient communication and regulatory compliance to facilitate smooth transitions between reference and biosimilar products. Clinicians express willingness to embrace interchangeable biosimilars to reduce administrative burdens and ensure uninterrupted patient care, underscoring the importance of effective communication and documentation within healthcare systems.
