About this trial
This observational study aims to identify genes that may affect how patients with inflammatory bowel disease respond to anti-TNF treatment and why some patients lose response to treatment over time. The study will examine whether genetic markers can help predict which patients are more likely to respond to anti-TNF therapy.
Participants who have not previously received anti-TNF treatment and are about to start advanced therapy will provide a blood sample to test for the genetic markers. Participants will also undergo regular assessments of current treatment, disease activity, and inflammatory markers during follow-up.
