• Study description:
  Due to their high cost, biological drugs threaten the sustainability of the Italian National Health Service and, therefore, it is crucial to ensure their appropriate use in clinical practice. Since 2006, following the patent expiry of some biologic drugs, the first biosimilar drugs have been introduced in the European market. They are defined by the European Medicines Agency as biologic drugs similar to the originator in terms of quality, efficacy and safety. In the context of inflammatory bowel diseases (IBDs) such as Crohn disease and ulcerative colitis, a large number of biosimilars concerning anti-TNF alpha inhibitors (adalimumab and infliximab) have been marketed, while for other more recent biological drug classes such as interleukin or integrin inhibitors patent expiry has not been occurred yet. ; ; Switching between biological drugs, both originator and biosimilar, in patients affected by IBD is a frequent phenomenon in clinical practice (from 5 to 30% during the first year of therapy). Moreover, in September 2022 EMA stated that biosimilars are comparable to their reference products in terms of safety and immunogenicity and are therefore interchangeable. However, for a single molecule numerous biosimilars are marketed and switching patterns among biological drugs might be very various and complex. Nonmedical switching could also lead patients to a nocebo effect if not well motivated to patients who know little about biosimilars. For these reasons, it is essential to explore what is happening in clinical practice in patients affected by IBDs.
