Biosimilars in IBD: What Every Clinician Needs to Know.

Abstract

Biosimilars were introduced to decrease biologic-related expenditures, but their uptake in inflammatory bowel disease (IBD) remains suboptimal. Herein, we review biosimilar concepts, current products available for IBD treatment, and resources to support biosimilar utilization. Although a cornerstone of IBD treatment, biologics are costly due to their development. Biosimilars, which are biologic products highly similar to a reference product, aim to decrease these expenditures. Infliximab, adalimumab, and ustekinumab biosimilars are approved for IBD, but uptake remains low due to biosimilar efficacy and safety concerns and delayed market entry. Clinicians can effectively address some of these barriers and help patients and healthcare systems reap the benefits of decreased costs and increased treatment access. Data shows comparable efficacy and safety outcomes with biosimilars in IBD. Several biosimilar products are available and in the pipeline, but efforts are needed from various stakeholders to bolster utilization and generate benefits.
