Combined Advanced Targeted Therapy for Inflammatory Bowel Disease

The aim of this retrospective and prospective observational study is to investigate and compare the real-world effectiveness and safety of different dual-target combination therapies in patients with inflammatory bowel disease (IBD). The key questions to be addressed are: In patients with refractory IBD who receive either two biologic agents or one biologic agent plus one small molecule drug, what is the real-world effectiveness and safety of different combination regimens? The researchers will conduct a retrospective analysis of medical records and electronic health data from patients diagnosed with IBD, and will enroll and document patients receiving combination advanced targeted therapy (CATT) for long-term follow-up. The treatments received by these patients are part of routine first-line clinical care or routine rescue clinical care. All treatment decisions were made by treating clinicians according to the standard of care; the investigator did not assign or modify any therapeutic interventions. Data will be collected during a defined follow-up period to compare the real-world effectiveness and safety profiles of different treatment exposure strategies.
