Outcomes
Primary outcome [1] 331177 0
Feasibility of autologous cord blood collection and cell retrieval following antenatal diagnosis of fetal stroke, as proven by at least 20 mls of cord blood collected after cord clamping at birth (cord collection by research team)
Timepoint [1] 331177 0
At the end of cord blood collection and processing (first 48 hours)
Primary outcome [2] 331178 0
Safety of umbilical cord blood derived cells (UCBC) administration as determined by absence of any adverse events (AE) necessitating cessation of cell infusion (e.g. anaphylaxis or major change in cardio-respiratory status), or any AE attributable to cell administration within first 48 hours of infusion (e.g. bacterial infection).
These will be assessed by close monitoring and collection of data on a case report from by research team.
Timepoint [2] 331178 0
48 hours post cell infusion(s)
Secondary outcome [1] 409095 0
Neurodevelopmental assessments at 3-4 months (GMA, HINE)
Timepoint [1] 409095 0
3-4 months of (corrected) age
Secondary outcome [2] 409096 0
Neurodevelopmental assessments at 1 year (HINE, GMFM-66 scale)
Timepoint [2] 409096 0
1 year (corrected) age
Secondary outcome [3] 409097 0
Neurodevelopmental assessments at 2 year (BSID-IV, hearing, vision, physical assessment).
Timepoint [3] 409097 0
2 years corrected age

Eligibility
Key inclusion criteria
Infants with brain injury associated with fetal stroke after confirmation of brain injury on postnatal imaging (Cranial ultrasound, MRI brain) soon after birth. Whilst there is no gestational age cut off, it is expected most infants will be born at or near term gestation.
Minimum age
5 Days
Maximum age
14 Days
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Infants who are likely to have redirection of care (palliation) for any reason.

Summary
Brief summary
We propose that i) collection of sufficient cord blood will be feasible in infants with antenatally diagnosed fetal stroke, and ii) (multiple) autologous intravenous administration of processed umbilical cord blood derived cells in these infants in the newborn period will be safe.
This phase I trial will be the first study in the translational pipeline for this neurological condition, and will test the feasibility of cord blood collection, sufficient cell availability and safety of cell administration in this vulnerable group. Following successful completion of this study, an efficacy trial will be planned to determine the efficacy of autologous UCB cell administration in fetal stroke.
