Combined Advanced Targeted Therapy for Inflammatory Bowel Disease
Efficacy and Safety of Combined Advanced Targeted Therapy for Inflammatory Bowel Disease: A Prospective, Multicenter, Real-World Study
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.

IBD Patients with Combined Advanced Targeted Therapy
Group/Cohort Description: This retrospective and prospective observational cohort includes patients with inflammatory bowel disease (IBD) who received combination therapy (two biologic agents or one biologic agent and one small molecule agent) in routine clinical practice.
All treatment decisions were made by treating clinicians according to the standard of care; the investigator did not assign or modify any therapeutic interventions, and only retrospectively collected and analyzed clinical outcomes from medical records.
|
Combination therapy in this study is defined as the concurrent use of either two biologic agents, or one biologic agent together with one small molecule agent.
