Could a bile acid pill in breast milk protect babies from liver problems?
NCT ID NCT07517276
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether giving a bile acid pill (TUDCA) to breastfeeding mothers with fatty liver disease can make their breast milk healthier for their babies. Eighty mother-infant pairs will be randomly assigned to receive TUDCA or a placebo for a short time after birth. The goal is to see if the treatment is safe and improves infant metabolism and development.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tauroursodeoxycholic acid (TUDCA)
- What this could lead to
- If successful, this could point toward a safe way for mothers with MASLD to improve their breast milk composition and support healthier infant development.
- What could go wrong
- This is an early Phase 2 trial with only 80 participants, so results may not apply widely. The treatment is for mothers, not directly for infants, and safety or effectiveness may not be confirmed.

Inclusion Criteria: * Lactating mother aged 18 to 45 years * Within 72 hours after delivery at screening * Intention to continue breastfeeding or providing expressed breast milk during the treatment period * Maternal metabolic dysfunction-associated steatotic liver disease (MASLD) defined by protocol-specified clinical criteria * Early postpartum breast milk sample meeting the predefined high-risk bile acid hydrophobicity index threshold * Live-born infant considered clinically stable and eligible for enteral feeding * Ability and willingness to provide written informed consent for maternal participation and infant-related study procedures Exclusion Criteria: * Maternal chronic liver disease other than MASLD, decompensated liver disease, biliary obstruction, acute cholecystitis, or pancreatitis * Current use of ursodeoxycholic acid, tauroursodeoxycholic acid, or another protocol-prohibited bile acid-modifying medication * Maternal severe renal insufficiency or other clinically significant condition judged by the investigator to increase study risk * Preterm infant less than 37 weeks of gestation or birth weight less than 2500 g * Major congenital anomaly or infant condition requiring ongoing intensive care at enrollment * Any condition that, in the investigator's judgment, makes the mother-infant dyad unsuitable for participation
