Using a device to stimulate the vagus nerve to help infants feed better

BabyStrong taVNS-Paired Bottle Feeding to Improve Oral Feeding

Phase 1 Interventional Medical University of South Carolina · NCT04849507

This study is testing a new device that stimulates a nerve in the ear to see if it can help infants who have trouble feeding better and avoid needing a feeding tube.

What this trial studies

This Phase I study investigates the BabyStrong feeding system, which delivers transcutaneous auricular vagus nerve stimulation (taVNS) to improve oral feeding in infants who are struggling to feed adequately. The study will involve infants receiving either active or sham stimulation paired with bottle feeding over a 10-day period, with a crossover design if no progress is made. The primary outcomes will include changes in daily feeding volumes and diffusion MRI assessments of brain structure. The study aims to determine the safety and efficacy of this novel approach in preventing the need for G-tube placement in infants.

Who should consider this trial

Good fit: Ideal candidates are infants of any gestational age who have been unable to feed orally after a specified period and are likely to need a G-tube.

Not a fit: Patients with cardiomyopathy, unstable bradycardia, or significant respiratory support may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve feeding outcomes for infants at risk of requiring G-tube placement.

How similar studies have performed: Previous studies using vagus nerve stimulation in similar contexts have shown promising results, indicating potential for success in this novel application.
