Baby BAC II

History of the Baby BAC Study at Duke

Thousands of newborn infants are born each year with signs of brain injury caused by lack of adequate blood flow and oxygen delivery. Two thirds of these babies would either die, or survive with neurologic deficits. A decade ago, Duke was among a group of hospitals caring for these infants reporting that lowering these infants’ body temperature for three days, called therapeutic hypothermia, could improve the odds of survival free of neurologic deficits for these infants, but still up to one half of these infants would die or survive with impairments, indicating the need for interventions in addition to cooling.

Over the past twenty years, Duke researchers have worked to understand the special biologic and restorative properties of progenitor and stem cells collected from umbilical cord blood for cord blood transplants for cancer, and for newborns with progressive degenerative lethal brain diseases. As a result, Duke investigators and colleagues from multiple other institutions have found that giving the cells to newborn animals with brain injuries can improve outcomes.

With this promising evidence, Duke investigators, led by Michael Cotten, MD and the NRPU, along with Joanne Kurtzberg, MD and the Duke Stem Cell Laboratory and the Carolinas Cord Blood Bank and the Maternal Fetal Medicine Division, started the Duke Baby BAC study. The pilot for Baby BAC used the baby’s own cord cells for newborn infants who had signs of brain injury. Results from the first 23 infants were published in 2014 in the Journal of Pediatrics, and subsequent enrollment of 52 subjects was completed in 2016.

Phase II for Baby BAC started in 2016 with funding provided by the Robertson Foundation. The Cerebral Palsy Alliance of New York has also provided us additional funding to help support this important project. Phase II was a multi-center, placebo-controlled study that was actively recruiting across several other centers across the country. The goal was to enroll a total of 160 subjects, however, due to slower than predicted enrollment, the funding for this trial was withdrawn, and the study has closed at the external sites. Duke as a site is currently on hold to enrollment but remains committed to this project. Duke is currently exploring other funding opportunities to ensure that Duke as a site can continue in the near future.

A challenge to generalizability of these types of clinical trials, and potential use of autologous (the baby’s own) cord blood cells is that approximately two thirds of infants born with neonatal brain injury do not have cells available. Duke has developed human cord tissue-derived mesenchymal stromal cells from umbilical cord tissue donated by third party donors and is currently testing these cells as an investigational product under the guidance of the Federal Drug Agency (FDA) in children. This product allows for a readily available ‘off-the-shelf’ cellular intervention product for neonatal brain injury. Duke has been funded by the Duke Clinical & Translational Science Institute to demonstrate the safety of infusion of these cells in a small cohort of newborns both with hypoxic-ischemic encephalopathy. This study will be open for enrollment by January 2019.

How you can participate

If you currently have a baby in the Duke Intensive Care Nursery, and you think you may want to participate in any of our research studies, please ask your baby’s nurse or doctor to contact us. The NPRU team will then contact you to explain the criteria for study eligibility and describe the potential benefits and risks for entering the study.
