BabyStrong II taVNS to help infants with feeding delays learn to feed

BabyStrong II (Stimulating the Tragus for Neural Growth): A Randomized Controlled Trial of taVNS-Paired Bottle Feeding to Improve Oral Feeding

Phase2; Phase3 Interventional Medical University of South Carolina · NCT07049952

This study tests whether twice-daily, gentle electrical stimulation of the vagus nerve at the ear (taVNS), with an added antioxidant (N‑acetylcysteine) for infants of diabetic mothers when appropriate, helps newborns and term infants with feeding delays reach full oral feeds faster than sham stimulation.

What this trial studies

This is a randomized, controlled, triple-blinded trial testing the BabyStrong taVNS feeding system in infants with feeding delays, with sites led by the Medical University of South Carolina. Infants are stratified by infant-of-diabetic-mother (IDM) status and randomized to active taVNS (with or without N‑acetylcysteine for IDMs) or sham stimulation, with blinded treatment for 14 days followed by an optional open-label phase of up to 10 days. The main outcomes are the number of infants reaching full oral feeds, daily oral feeding volumes, and time to full feeds. The trial builds on pilot results and aims to generate safety and efficacy data to support an FDA submission and commercial development.

Who should consider this trial

Good fit: Ideal candidates are near-term or term infants (meeting the protocol's postmenstrual age and duration-of-feeding criteria) who are making minimal progress with oral feeds and are allowed to attempt PO feeding without therapist-imposed volume limits.

Not a fit: Infants with unstable apnea or bradycardia, significant respiratory support (CPAP/Vapotherm), cardiomyopathy, unrepaired major congenital anomalies that affect safe oral feeding, or congenital syndromes unlikely to feed are excluded and unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, the device could help more infants reach full oral feeds sooner, reduce the need for gastrostomy tubes or prolonged nasogastric feeding, and allow earlier discharge home.

How similar studies have performed: Early pilot work showed promising results, with 54% (19/35) of infants reaching full oral feeds within two weeks, but the approach remains relatively novel and has not yet been tested in a large randomized trial.
