Comparing Vedolizumab and Adalimumab for Crohn's Disease Treatment

Comparison of Vedolizumab Treatment to Adalimumab Dose Intensification in Crohn's Disease Patients With Loss of Response or Biomarker Activity to Adalimumab on First Line With Therapeutic Drug Concentration: A Randomized, Multicentre, Controlled Trial

Phase 4 Interventional Centre Hospitalier Universitaire de Saint Etienne · NCT06180382

This study is testing whether switching to Vedolizumab or increasing the dose of Adalimumab works better for people with Crohn's disease who aren't responding to their current Adalimumab treatment.

What this trial studies

This clinical trial evaluates the effectiveness of Vedolizumab compared to intensifying the dose of Adalimumab in patients with Crohn's disease who have lost response to Adalimumab despite having therapeutic drug levels. The study aims to determine the best intervention strategy for these patients by assessing drug levels and antibodies to guide treatment decisions. It involves a combination of therapeutic drug monitoring and clinical assessments to optimize patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults with Crohn's disease who initially responded to Adalimumab but are experiencing a loss of response while maintaining therapeutic drug levels.

Not a fit: Patients who have previously used Vedolizumab or Ustekinumab for Crohn's disease or those with certain medical histories may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment strategy for Crohn's disease patients experiencing loss of response to Adalimumab.

How similar studies have performed: Previous studies have shown that switching to another class of medication can be beneficial for patients with secondary loss of response, indicating potential success for this approach.
