Preventing Crohn's disease recurrence after surgery with EXL01

A Phase 2 Multicentre, Randomised, Parallel-arm, Placebo-controlled, Double-blind Study to Evaluate the Safety and Target Engagement of EXL01 in the Prevention of Post-operative Recurrence of Crohn's Disease

Phase 2 Interventional Saint-Louis Hospital, Paris, France · NCT06925061

This study is testing if a new oral medication called EXL01 can help prevent Crohn's disease from coming back after surgery in people who have just had an operation for it.

What this trial studies

This Phase 2 clinical trial evaluates the effectiveness of oral EXL01 in preventing post-operative endoscopic recurrence of Crohn's disease. Approximately 80 patients who have undergone surgery for Crohn's disease will be randomly assigned to receive either EXL01 or a placebo for up to 24 weeks. The study aims to assess the endoscopic modified Rutgeerts scores at 6 months post-surgery to determine the impact of EXL01 compared to placebo. Participants will be monitored for safety throughout the study.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who have undergone ileocecal or ileo-colonic resection for Crohn's disease and are not scheduled to receive anti-TNF agents post-surgery.

Not a fit: Patients who have not adequately recovered from surgery, have a current stoma, or are scheduled for biotherapy other than anti-TNF agents may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce the recurrence of Crohn's disease after surgery, improving long-term patient outcomes.

How similar studies have performed: Other studies have explored similar approaches in managing Crohn's disease recurrence, but the specific use of EXL01 in this context is novel.
