Using Tacrolimus and Indomethacin to Prevent Pancreatitis After ERCP

A Randomized Trial Comparing Rectal Indomethacin Alone Versus a Combination of Rectal Indomethacin and Oral Tacrolimus for Post-ERCP Pancreatitis Prophylaxis

PHASE3 · Johns Hopkins University · NCT05252754

This study is testing if taking a medication called tacrolimus before a procedure to remove bile duct stones can help prevent pancreatitis in patients.

What this trial studies

This clinical trial investigates whether administering oral tacrolimus before endoscopic retrograde cholangiopancreatography (ERCP) can reduce the risk of post-ERCP pancreatitis. The study compares the effectiveness of tacrolimus combined with rectal indomethacin against a placebo in patients undergoing ERCP. Given the high incidence and cost burden of post-ERCP pancreatitis, this trial aims to explore a novel approach targeting the underlying mechanisms of this complication. The study will enroll patients who meet specific eligibility criteria and will be conducted at multiple locations, including Johns Hopkins Hospital and facilities in India.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who are scheduled to undergo ERCP and can provide informed consent.

Not a fit: Patients with chronic pancreatitis, recent acute pancreatitis, or those with contraindications to tacrolimus or NSAIDs may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of post-ERCP pancreatitis, improving patient outcomes and reducing healthcare costs.

How similar studies have performed: While some studies have explored preventative measures for post-ERCP pancreatitis, the use of tacrolimus in this context is a novel approach.
