Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Cord blood collection and processing: Minimum cord blood collection volume for inclusion in the trial will be 9 mLs. The collected cord blood (>9 mLs) will be processed according to standard cell processing operating procedures, aliquoted and cryopreserved.

Storage and release: An aliquot containing sufficient numbers of UCBCs, according to weight of the preterm infant, required for early administration will be stored. Cell Care (Heatherton, VIC), a TGA accredited cord blood bank, will be responsible for collection, processing, storage of all samples and release of UCBC. Standard testing for impurities, cell viability and HLA matching of UCBC to the preterm infant’s HLA will be performed before release of UCBCs. Criteria for product release will include: free of microbial contamination after 7 days of culture, cell viability > 90% as determined by trypan blue exclusion at the time of cryopreservation, and HLA match from cord blood and infant sample.

Thawing and infusion preparation: On the day of infusion, UCBCs will be retrieved from liquid nitrogen storage, and once product release criteria are met, frozen UCBC aliquot will be transported to Monash Health. Cells will be thawed using a pre-warmed heat block for approximately 2 minutes. The UCBCs will be washed with dextrose/ albumin and centrifuged at 350g for 5 minutes prior to resuspension in dextrose/ albumin at the final desired concentration. The UCBCs will be suspended at a concentration 10% greater than the desired concentration to allow for cell loss. Volume of cell infusion prepared will be around 10 mL/kg. A final cell viability will be done just prior to administration.

Autologous transplantation of umbilical cord blood derived stem cells (intravenous)
UCBCs will be administered ONCE intravenously (through a peripheral intravenous catheter) at a dose of 25-50 million viable cells/ kg body weight, 25 million/kg being the proposed minimum dose, and 50 million/kg being the maximum dose.

UCBCs from autologous cord blood collection administered intravenously to infants, between D9 – D15 of life.

Summary
Brief summary
Preterm brain injury continues to be an important complication of preterm birth, especially in extremely premature and extremely low birth weight infants. Umbilical cord blood derived stem cells (UCBCs) are being increasingly evaluated for their neuroprotective and neuroreparative properties. There remains a paucity of information on the feasibility and safety of autologous UCBC transplantation in extremely premature infants.

Methods: A single centre safety and feasibility study in preterm babies born before 28 weeks gestation. Cord blood will be collected after birth and, if sufficient blood is obtained, UCBC will be harvested from the cord blood, characterised and stored. After excluding infants who have already suffered severe preterm brain injury, preterm infants will be infused with autologous UCBC via the intravenous route at a dose of between 25-50 million UCBCs/kg body weight. A minimum of 20 infants will be administered autologous UCBCs. Primary outcomes will include feasibility and safety. Feasibility will be determined by access to sufficient cord blood at collection and UCBCs following processing. Safety will be determined by lack of adverse events directly related to autologous UCBC administration in the first few days after administration. Secondary outcomes studied will include neonatal, and neurodevelopmental morbidities till 2 years of life.
