Summary

ROLL'YN-UST is a real-life study, which includes patients in clinical remission for at least 3 months and who have been treated with a reference biotherapy for at least 6 months, and for whom the physician has decided, independently of the study and as part of a shared medical decision, to switch them to STEQEYMA®. The main aim of this study is to the maintenance of clinical remission 12 months after initiation of a biosimilar as well as patient satisfaction 6 and 12 months after initiation of a biosimilar.

Detailed description

Biotherapies have revolutionized the management of chronic inflammatory diseases in gastroenterology (Crohn's disease and ulcerative colitis), dermatology (e.g. plaque psoriasis and chronic spontaneous urticaria). However, due to their specificity and complexity, these treatments have a high financial cost, which has a significant impact on healthcare systems. Following the loss of patent protection for these reference biotherapies, biosimilars were developed. These are similar to the reference molecules, but not strictly identical. As a result, to obtain marketing authorization, a biosimilar must demonstrate equivalence to the reference biologic in terms of efficacy and safety in a single indication defined in a Phase I (pharmacokinetic) and Phase III (clinical) study, before being extrapolated to other indications, as applicable. This study aims to address these subjects for STEQEYMA® (CT-P43), a biosimilar ustekinumab approved by the European Commission on August 22, 2024, through a centralized procedure. STEQEYMA® is indicated for the treatment of moderate to severe forms of Crohn's disease (CD) and plaque psoriasis.
