Breastfeeding clinical trials at UCSF
2 in progress, 1 open to new patients

  • The Milk, Growth and Microbiota Study

    open to all eligible people

    Late preterm infants, who are born at 34, 35 or 36 weeks gestation, often have difficulty feeding, establishing growth, and fighting off infection. Breastfeeding provides improved nutrition to help fight infection, in part because breast milk encourages the growth of healthy bacteria (microbiota) in the infant's intestine. However, when mothers give birth preterm, their breasts are usually not quite ready to make milk; it can take several days to have enough breast milk to match a baby's nutritional needs. If there is not yet enough breast milk, formula is often used. However, formula can interfere with the growth of healthy intestinal bacteria. An alternate nutritional option is donor milk from a certified milk bank, which is available in all neonatal intensive care units (NICUs) in San Francisco. However, no scientific studies have yet studied donor milk for late preterm infants, so currently all San Francisco NICUs (as well as the large majority of NICUs nationwide) reserve donor milk for infants born at <34 weeks. This study's investigators therefore propose the "Milk, Growth and Microbiota (MGM) Study," a randomized controlled trial to compare banked donor milk to formula for breastfeeding late preterm infants born in San Francisco. Once enrolled in MGM, infants will be randomly assigned to receive either formula or banked donor milk if they need additional nutrition until their mothers are making enough milk. After enrolling the babies, investigators will weigh them daily to assess their growth. The investigators will also collect infant bowel movements at baseline, 1 week and 1 month to determine whether donor milk vs. formula impacts the type of bacteria in the baby's intestine. If the study's results show that donor milk optimizes growth while helping establish healthy bacteria in the baby's intestine, donor milk might be postnatal strategy to bolster neonatal nutrition for late preterm infants.

  • Early Limited Formula for Treating Lactation Concerns

    Sorry, in progress, not accepting new patients

    This is a randomized, controlled trial designed to evaluate a new strategy for promoting continued breastfeeding for mothers and babies who initiated breastfeeding in the newborn period. The new strategy, called Early Limited Formula (ELF), consists of 10mL of formula fed to each baby by syringe after each breastfeeding prior to the onset of mature milk production. The study intervention is discontinued at the onset of mature milk production, and the investigators will then follow mothers and infants for 12 months to assess the effect of ELF on breastfeeding duration, maternal experience and healthcare utilization.
