BOOM-IBD2 Pivotal Neuromodulation for Ulcerative Colitis

Official title: BOOM-IBD2 Clinical Trial to Evaluate the Effectiveness of Sacral Neuromodulation for the Treatment of IBD.

Run by Boomerang Medical · NCT06571669 · Data updated 2026-11-12

This study tries a small device placed under the skin that sends mild signals to a nerve near the tailbone to reduce bowel urgency in adults with ulcerative colitis.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–85 with a diagnosis of ulcerative colitis who experience bothersome bowel urgency and can consent and attend follow-up visits are the ideal candidates.

Probably not a fit

People with active colonic infections (such as C. difficile or CMV), colonic perforation, fulminant colitis requiring emergency surgery, certain other colitis types, unresected colonic neoplasia, strictures preventing colonoscopy, significant comorbid medical or psychiatric conditions, or other listed exclusions are unlikely to be eligible or benefit.

What this trial studies

The trial implants a small neuromodulation device under the skin near the tailbone during a same-day procedure to deliver mild electrical signals to a nearby nerve. All enrolled adults (ages 18–85) with ulcerative colitis receive the device; there is no placebo or sham group. The primary outcome is change in bowel urgency at 12 weeks measured with a standard urgency rating scale, and participants are followed with visits for 12 months. The approach aims to alter neural signaling to improve urgency and related bowel symptoms.

Why it matters

Potential benefit: If successful, the device could reduce bowel urgency and improve daily function and quality of life for people with ulcerative colitis.

How similar studies have gone: Related nerve-stimulation approaches like sacral neuromodulation have shown benefits for some bowel disorders, but this specific subcutaneous tailbone-directed device is relatively new and less well studied.
