Plain English Summary
Background and study aims
Docosahexaenoic acid (DHA), choline and uridine-5-monophosphate are dietary factors known to support healthy brain growth and development. These 'neurotrophic' factors are passed from a mother to her baby during pregnancy, with the highest levels being passed to the baby in the third trimester of pregnancy. Many people have diets lacking in these factors. In addition, babies born prematurely will not receive enough of these factors. Babies at risk of brain impairment may not have enough neurotrophic factors to allow the brain to perform natural repair processes, and to help support healthy brain growth and development. Children with brain impairment can also grow less well than children without brain impairment. The aim of this study is to assess whether or not providing adequate amounts of neurotrophic factors can improve growth and developmental outcome in babies at risk of brain impairment.
Who can participate?
Babies at risk of brain impairment.
What does the study involve?
Newborn babies eligible to join the study will be randomly allocated to receive either an active supplement containing the neurotrophic factors or a placebo (dummy) that does not contain the neurotrophic factors. This supplement will be taken every day for 2 years. Neither the parents nor the research team will know whether the baby is on the active or placebo supplement. All babies in the study will also receive support from the study dietician to make sure that they receive a healthy balanced diet and to provide help and advice with supplement administration. During the 2-year study the growth and developmental progress of each baby will be followed by the research team. Participants will also have a blood test measuring DHA levels at the beginning and end of the study. A magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS) scan assessing brain choline levels will be performed at the beginning of the study and at 3 months of age. A further MRI and MRS scan will also be performed at the end of the study in those children who need a scan for clinical reasons.
What are the possible benefits and risks of participating?
Babies who participate in the study may have improved growth and developmental outcome. The disadvantages of taking part are that the assessments and tests involved will require more time spent in hospital.
Where is the study run from?
Department of Paediatrics, University of Oxford (UK).
When is the study starting and how long is it expected to run for?
The study opened in September 2009 and will recruit participants until December 2012. The study will close in December 2014 when the last children taking part have completed their involvement with the study.

Condition
Neurodisabilities in neonates
Intervention
The intervention is in the form of a neurotrophic supplement containing docosahexanoic acid (DHA), uridine mono-phosphate (UMP) and choline, along with supportive vitamins and minerals. The control being used is an iso-caloric, iso-nitrogenous placebo substance.
The active supplement or control will be taken daily and added to feed or food. This can be taken orally or via a feeding tube and supplementation will continue for the whole 2 years of the study.
Follow Up Length: 24 month(s)

Drug names
Docosahexanoic acid (DHA), uridine mono-phosphate (UMP) and choline
Primary outcome measures
1. Neurodevelopmental outcome as assessed by using the Bayley Scale of Infant Development. A clinically significant improvement translates as ~10 points on the Bayley Scale (assuming Standard Deviation (SD) of ~12)
2. Growth measure as assessed using anthropometry (weight, height, skinfold measurements and head circumference)
Secondary outcome measures
1. Electrophysiology: Visual Evoked Potential and behavioural vision testing - tested at baseline, term (if applicable), 6, 12 and 24 months post entry into study
2. Neuroimaging: changes of brain biochemistry and choline uptake as estimated by Magnetic Resonance Spectroscopy (MRS) at baseline and 3 month follow-up
