Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Infants born at <29 weeks gestation at high risk of bronchopulmonary dysplasia (BPD) as assessed by respiratory support and oxygen requirements on Day 14 of life will receive intravenously administered allogeneic human amnion epithelial cells (hAECs). The dose of cells will increase between patient cohorts beginning with 2 million hAECs/kg in a single dose reaching 30 million hAECs/kg in 3 divided doses given at 5 day intervals. The dosing schedule is provided below.
Infants 1-3: 2 million hAECs/kg
Infants 4-6: 4 million hAECs/kg
Infants 7-9: 8 million hAECs/kg
Infants 9-12: 10 million hAECs/kg
Infants 13-18: 20 million hAECs/kg in 2 divided doses given at 5 day intervals
infants 19-24: 30 million hAECs/kg in 3 divided doses given at 5 days intervals
hAEC suspension will be prepared by the Amnion cell biology research group at Monash Health Translation Precinct's Cell therapy platform. hAEC suspension will be manufactured in accordance with good manufacturing practice.

Outcomes
Primary outcome [1] 305999 0
The primary outcome is safety of hAEC infusion in infants <29 weeks gestation. Safety will be determined by the occurrence of adverse events.
Adverse events will be defined as;
- Cardiorespiratory Instability and/or Anaphylaxis within 72 hours of hAEC infusion
- Infection within 72 hours of hAEC infusion
- Allogeneic Rejection
- Tumour formation
- Local Site Reaction
Routine care within intensive care and special care nurseries will inform much of the primary outcome. In addition to routine care, screening for potential adverse events will include;
- MRI brain and abdominal ultrasound at 36 weeks PMA, Cranial ultrasound at 6 months corrected age, Chest XRay and abdominal ultrasound at 6, 12 and 24 months corrected age for assessment of tumorgenicity
- Fortnightly blood tests of liver and renal function for duration of hospital admission to assess for evidence of allogeneic rejection
Timepoint [1] 305999 0

72 hours post hAEC infusion
7 days post hAEC infusion
