Safety and Feasibility Study of Umbilical Cord Blood Cells for Infants With Hypoplastic Left Heart Syndrome
Autologous Cord Blood Cells for Patients With HLHS: Phase I Study of Feasibility and Safety

Further study details as provided by Duke University:

Purpose: To evaluate the feasibility and safety of collecting and infusing autologous umbilical cord blood (UCB) in newborn infants with hypoplastic left heart syndrome (HLHS).

Study Rationale and Hypotheses: The major goal of this study is to determine whether infusion of autologous UCB cells in neonates with hypoplastic left heart syndrome is feasible and safe. The rationale for the study and for the potential benefit of UCB is based upon the following hypotheses:

  1. Infants with HLHS have significant neural injury evidenced from both prenatal and early antenatal brain MRI findings and infusion of UCB cells may lessen neural injury. Although the exact mechanism is unknown, UCB cell infusion may ameliorate neural injury via paracrine and anti-inflammatory effects that enhance post injury repair and may promote endogenous functional compensation of other cortical areas resulting in significant clinical improvements.
  2. UCB cells may also enhance cardiac function, minimize scar formation, and reverse detrimental remodeling after cardiac injury.

The purpose of this pilot study is to evaluate the safety and feasibility of infusions of autologous (the patient's own)umbilical cord blood cells in neonates with hypoplastic left heart syndrome. This is a prospective, randomized Phase I trial designed to assess the safety and feasibility of autologous UCB reinfusion in neonates with Hypoplastic Left Heart Syndrome (HLHS). Neonates who are identified prenatally as having a cardiac lesion consistent with HLHS will be referred to Duke Cardiology for further evaluation. If they meet inclusion criteria, UCB will be collected at the time of delivery and processed (red blood cell- and volume-reduced) for reinfusion. All enrolled infants will receive a dose of fresh UCB cells pre-operatively and ½ of the enrolled infants will be randomly selected to receive a second dose of frozen and thawed UCB cells after stage 1 palliation (5-35 days post-operatively) and a third dose of frozen and thawed UCB cells 2 to 4 weeks after the 2nd infusion. Neurodevelopmental outcome measures will be assessed at 1 month after discharge, at 4-6 months old and 12 months. The results of MRI's and echocardiograms that are obtained per clinical routine will be analyzed and described in study reports.

Phase 1
Allocation: Randomized
Endpoint Classification: Safety Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Hypoplastic Left Heart Syndrome
  • Biological: Autologous Umbilical Cord Blood
    Infants who meet study enrollment criteria for hypoplastic left heart syndrome in the neonatal period will receive 1 infusion of their own volume reduced cord blood cells. The dose for each infusion is 5x10e7 cells/kg.
  • Biological: Autologous Umbilical Cord Blood
    Infants who meet study enrollment criteria for hypoplastic left heart syndrome in the neonatal period will receive 3 infusions of their own volume reduced cord blood cells. The first infusion will be a fresh, volume-reduced infusion and the subsequent infusions will be thawed and washed infusions. The dose for each infusion is 5x10e7 cells/kg.
  • Experimental: Single infusion of UCB
    (autologous red blood cell and volume reduced cord blood cells)
    Intervention: Biological: Autologous Umbilical Cord Blood
  • Experimental: Three infusions of UCB
    (autologous red blood cell and volume reduced cord blood cells)
    Intervention: Biological: Autologous Umbilical Cord Blood

Inclusion Criteria:

  • Infants > 35 weeks gestational age.
  • Diagnosis: Hypoplastic Left Heart Syndrome.

  • Parental Consent.

Exclusion Criteria:

  • Chromosomal anomalies identified before the time of infusion.
  • Chromosomal anomalies or congenital anomalies that would prohibit clinicians from initiating surgical repair of the congenital heart defect.
  • Infant is determined by clinical staff to be non-viable and will not receive aggressive care. (No member on the study team will be involved in determining the viability of the neonate.)
