In a population of adult patients followed for Crohn's disease, who had previously agreed to replace Stelara® with a biosimilar of ustekinumab (Uzpruvo®) and were followed over a period of 12 months under usual medical practice conditions. * Main objective: To assess the maintenance of the biosimilar of ustekinumab at 12 months without returning to the reference treatment * Secondary objectives: * To describe the factors associated with the maintenance of the biosimilar * To evaluate the evolution of patients' quality of life * To assess the rate of maintenance of clinical remission at M12 * To describe the acceptability of the biosimilar treatment by patients * To evaluate patient satisfaction * To evaluate treatment tolerance * To describe the reasons for treatment discontinuation that occurred during follow-up * To describe the profile of patients who discontinued treatment upon their request.
This is an open-label, prospective, longitudinal, multicenter, observational cohort study involving a population of adult patients for whom the investigating physician, prior to inclusion, decided with their consent to replace Stelara® with Uzpruvo® (a biosimilar of ustekinumab). This observational study does not alter the physician-patient relationship or standard patient care. Physicians retain freedom in their prescriptions and follow-up procedures; no specific procedures or tests are required of patients beyond the completion of self-assessment questionnaires. The study is longitudinal, and the proposed assessments remain within the framework of the patients' standard follow-up with their physician. This study is classified as RIPH 3 (minimally or not at all interventional). The conduct of the treatment (dosage, administration schedule, etc.) is left to the discretion of the investigating physician in compliance with the MA, according to their clinical practice and the patient's therapeutic history. Similarly, the investigating physician remains the sole judge of the continuation or interruption of ustekinumab or its replacement by another biotherapy or by any other treatment. All treatments associated with ustekinumab as part of the management of the condition that prompted biotherapy that will be prescribed during the study must be reported in the observation log.

Quality of life - EQ-5D-5L
The EQ-5D-5L questionnaire is a European quality of life scale comprising two parts: a first part with questions known as the "EQ-5D descriptive system," supplemented by a visual analog scale, called the "EQ-5D VAS." It consists of a 20 cm line, graduated from 0 to 100, on which the patient must indicate how they assess their current health, with 0 being the worst possible state and 100 the best.

Crohn's disease activity
The Harvey-Bradshaw Index is the most widely used tool for assessing Crohn's disease activity in current practice. It comprises five items (general well-being, abdominal pain, number of loose stools per day, abdominal mass, and extradigestive signs). A score \< 4 corresponds to inactive disease; a score between 4 and 12 to active disease; a score above 12 to very severe active disease.
