Plain English Summary

Background and study aims
This study is designed to test whether adding a daily nutrient supplement (food substance) to the normal milk and weaning foods of babies born very early can help improve their brain development, and their neurological child development (such as how they think, communicate, play and interact with others). The supplement contains substances that occur naturally in a healthy diet and are often used as food supplements (long-chain polyunsaturated fatty acids, uridine-5’-monophosphate, cytidine-5’-monophosphate, and choline). A small UK study has been carried out and the results were promising, but we need to find out more. The aim is to include about 500 babies born very early and 500 babies who receive cooling treatment in order to be confident of finding out whether the supplement improves the babies' brain development, and neurological child development, or not. If the study shows that the supplement is effective, it might be given to babies as part of future NHS care.

Who can participate?
Babies born more than 12 weeks early and babies born less than 5 weeks early who have received cooling treatment for hypoxic-ischaemic encephalopathy (HIE)

What does the study involve?
Once consent is provided, the infant will receive either the supplement or a substance that looks the same but does not contain the nutrients (a placebo). There is a 50% chance of receiving the supplement and a 50% chance of receiving placebo. The supplement will be given daily to the infant until he/she is 12 months after the Estimated Date of Delivery (EDD). Parents will be asked to complete questionnaires when they join the study, at hospital discharge and at 3, 6, 12, 18 and 24 months of age.

What are the possible risks and benefits of participating?
The supplement has been used in a smaller study of around 100 babies and infants without any problems or side effects. All babies will be monitored very closely throughout the study by the clinical team in the Neonatal Intensive Care or Special Care Unit, and by the local NHS Paediatrician and clinical team following discharge from hospital. Participants who take part in the trial to the time their child is age 24 months will receive a £25 voucher.

Where is the study run from?
The National Perinatal Epidemiology Unit, Clinical Trials Unit (NPEU CTU) at the University of Oxford, in partnership with Newcastle University (UK)

When is the study starting and how long will it run for?
September 2021 to May 2027

Who is funding the study?
The National Institute for Health Research (NIHR) Health Technology Assessment (HTA) programme (UK)

Study hypothesisThis study is designed to test whether adding a daily nutrient supplement (food substance) to the normal milk and weaning foods of babies born with hypoxic ischaemic encephalopathy (where the brain did not receive enough oxygen around the time of birth) or babies born premature (born less than 28 weeks of gestation) can help improve their neurological development in later childhood (such as how they think, play and interact with others).
Ethics approval(s)Approved 14/03/2022, Bristol Research Ethics Committee Centre, Ground Floor, Temple Quay House, BS1 6PN, UK; +44 (0)207 104 8029; centralbristol.rec@hra.nhs.uk), ref: 22/SW/0009
ConditionBabies born with hypoxic ischaemic encephalopathy (where the brain did not receive enough oxygen around the time of birth) or babies born premature (born less than 28 weeks of gestation)
InterventionThis trial aims to establish whether or not early life nutritional supplementation with a nutrient blend of long-chain polyunsaturated fatty acids (LCPUFAs), choline, uridine-5'-monophosphate (UMP), and cytidine-5’-monophosphate (CMP) improves infants’ cognitive development at 24 months post Estimated Date of Delivery (EDD), compared to controls, in two clearly defined strata:
1. Preterm stratum: Infants born less than 28 weeks of gestation
2. HIE stratum: Infants born at 35 weeks of gestation or more, receiving therapeutic hypothermia for HIE.

1,010 infants; 538 preterm and 472 infants born at or after 35 weeks of gestation with HIE cared for in neonatal units across the UK participate. A 9-month internal pilot phase incorporates “stop-go” criteria to evaluate the feasibility of recruitment and other trial processes. With informed consent from parents, clinicians in each unit will use a randomisation website to randomly allocate infants to receive either:
1. Treatment supplement: micronutrient breast milk/formula milk/food supplement containing LCPUFAs, choline, UMP, and CMP.
or
2. Matched placebo control supplement: identically packaged and delivered powder supplement indistinguishable from the active treatment.

Parents will be offered information about the trial and will have ample time to consider whether they wish their baby to take part. Eligible babies will be recruited up to 40 weeks of gestation plus 28 days.

Powder supplement will be added daily to the usual milk feed (breast or formula) on the neonatal unit when infants reach full milk feeds (120–150 ml/kg/day), and have reached 1 kg body weight.

Supplementation will be continued on discharge and given at home by parents until 12 months of age post EDD. Neither the clinicians, nor the caregivers, parents or carers will be aware of whether each individual infant is receiving active treatment or a placebo.

No additional (trial-specific) blood tests or other investigations will be required.

Parents will receive support from their local clinical teams whilst on the Neonatal unit and throughout the entire trial period.

Data will be collected on bespoke data collection forms from the time of randomisation up until the child reaches 24 months of age, post EDD. Parents will be asked to complete questionnaires when their child reaches 6, 12, 18 months of age post EDD and record if the supplement has been given on an App (or alternative method of parents choosing). The researchers will undertake an economic evaluation to determine whether supplementation is a cost-effective treatment.

Consent will be obtained to facilitate future school-age follow-up.
