Ustekinumab in BEhçet's Syndrome STudy

Sponsor: Groupe français d'étude des Maladies Inflammatoires de loeil

Summary

This non-interventional study is an observational cohort with parallel groups aiming primarily to describe the success of biosimilar of ustekinumab in Behçet's syndrome in whom conventional approaches have failed or are not suitable well tolerated, and then to compare with patients receiving apremilast within routine care. Ustekinumab previously prescribed subcutaneously at 90 mg on Week 0, 4, 12 and 20 within the standard of care. Following non-opposition to participate, patients data will be collected, which will comprise data of the 3-month interval medical visits, except for the first month of treatment, in which the short-term tolerance of treatments is usually assessed (ie, baseline visit, then week 4, 12, 24, 36 and 52). Clinical examination, biological tests and relevant clinical scores (BDCAF, BSAS and PhGA) data that were performed within routine care. No changes to patients' usual care will be made (no additional visits, additional examinations or questionnaires), their safety and well-being remaining therefore unchanged. Data will be collected from the participant's medical record (containing medical reports and examinations, biological tests, nursing records, etc.), for the period of participation in the research, with the only purpose of meeting the objectives of the research. Data will be collected using an electronic 'eCRF observation book on the REDCap platform. The following data will be collected: demographic data (age, sex, weight, height); clinical data (history of the disease, pathology diagnosed, activity of the pathology), treatments, biological data, adverse events. No genetic data will be collected as part of the study. No data will be transferred abroad. No additional questionnaires, examinations or visits will be added by the research. Activity indexes for BS will be calculated as part of routine care. The number, duration and intensity of oral ulcers of patients will be verified by the nurse or the site investigator according to the routine care. Patients' data with active mucocutaneous Behçet's manifestations with an indication of starting apremilast within standard of care (according to AMM and PNDS) will be retrospectively collected in order to establish a retrospective cohort for comparative purposes.
