NCT04236479

Brief Summary

The proposed study will be a prospective, open-label, single-center, safety and feasibility phase 1 trial of allogeneic bone marrow-derived mesenchymal stromal cell (BM-MSC) delivery though cardiopulmonary bypass (CPB) using a homogeneous population of infants with congenital heart disease (CHD) who will be undergoing a two-ventricle repair within the first six months of life

Conditions

Outcome Measures

Primary Outcomes (1)

  • Number of subjects who experience serious adverse events, adverse events, and/or early treatment discontinuations.

    Dose Limiting Toxicity is attributable to the MSC administration.

    45 days following the MSC administration

Secondary Outcomes (1)

  • Actual magnitude of differences in neuroimaging and neurodevelopmental variables will be measured after MSC delivery.

    18 months

Study Arms (1)

Bone marrow-derived mesenchymal stromal cell (BM-MSC)

EXPERIMENTAL

The dose-escalation methods with a modified continual reassessment at the five dose levels (1x10\^6, 10x10\^6, 20x10\^6, 40x10\^6, 80x10\^6 cells/kg) will be performed to determine safety and feasibility of allogeneic BM-MSC infusion during pediatric cardiac surgery and the maximum tolerated dose in infants with CHD.

Biological: BM-MSC

Eligibility Criteria

AgeUp to 6 Months
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Neonatal and young infantile patients who are ≤ 3 months of age
  • Scheduled to undergo reparative two-ventricle repair for congenital heart defects without aortic arch reconstruction, including the following:
  • a. D-Transposition of the Great Arteries (d-TGA) Group: i. d-TGA with intact ventricular septum (d-TGA, IVS) ii. d-TGA with ventricular septal defect (d-TGA, VSD) b. Ventricular Septal Defect (VSD) Group: i. VSD without aortic arch obstruction (AAO) ii. Complete common atrioventricular canal defect (CAVC) c. Tetralogy of Fallot (TOF) Group: i. Tetralogy of Fallot (TOF) ii. Tetralogy of Fallot with Pulmonary Atresia (TOF,PA) iii. Truncus arteriosus (TA) iv. Double outlet right ventricle (DORV)
  • Scheduled surgery at or before three months of age.
  • Parent/guardian capable of providing informed consent.

You may not qualify if:

  • Birth weight less than 2.0 kg
  • Recognizable phenotypic syndrome
  • Associated extracardiac anomalies of greater than minor severity
  • Previous cardiac surgery
  • Associated cardiovascular anomalies requiring aortic arch reconstruction and/or additional open cardiac surgical procedures in infancy
  • Prior severe hypoxic event
  • Significant screening test values that place subjects at increased risk of complications from participation in the study
