Validation of Endoscopic Activity Scores in Patients With Crohn's Disease Based on a Post Hoc Analysis of Data From SONIC

In patients with CD, mucosal healing and endoscopic response (defined as a decrease from baseline in SES-CD or CDEIS of at least 50%) at week 26 of treatment identified those most likely to be in CFREM at week 50. The ability of the proposed endoscopic response cutoff value to predict midterm CFREM should be validated in an independent, prospective cohort. Its correlation with changes in long-term disease progression still needs to be demonstration. ClinicalTrials.gov, Number: NCT00094458.
