Introduction:
The approval of biosimilars in the management of inflammatory bowel diseases (IBDs) has offered an answer to a growing concern about healthcare costs, and availability of treatments. Several studies have been conducted to demonstrate proof of biosimilars effectiveness as treatment in Crohn's disease (CD).
Areas Covered:
Since 2013, the European Medicines Agency has approved five biosimilars for infliximab and eight for adalimumab. Initial data leading to approval were extrapolated from studies conducted in patients with rheumatological or dermatological diseases, but recent studies filled the gap of clinical data among patients with IBD. In this review, 75 studies were included, with data from a total of 20 707 patients with CD. Clinical data on biosimilars in the treatment of CD show equivalence in terms of efficacy, either as induction or maintenance of treatment and regardless of previous exposure to originator or other biosimilar.
Expert Opinion:
Since biosimilar market entry, utilization of infliximab increased by 89.9% and by 22.4% for adalimumab in European countries. With a 10-year insight since the first approval of biosimilar in Europe, biosimilars prescriptions should be implemented in routine clinical practice given the efficacy and safety profile.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
