General information about the trial
|
|||
Main objective of the trial |
The overall purpose is to investigate whether melatonin, on achieving adult maternal peak blood levels in preterm infants, will reduce cerebral white matter disease as defined by specialised magnetic resonance imaging (MRI) at term. Before testing this hypothesis in a clinical trial, the dose of melatonin required to achieve the desired concentration in preterm infants needs to be determined. This data will be used in the clinical double blinded randomised trial for which a separate application will be made to the ethics committee.
The principal research objective in this study is to determine the dose required to achieve physiological melatonin blood levels in the preterm infants similar to that of the mother.

Recruitment
|
|||||||
Recruitment details |
The investigators conducted an open-label dose-ranging study between May 2010 and December 2010 in three neonatal intensive care units in the UK. Infants born less than 31 weeks gestation and less than 7 days old were eligible for the study. | ||||||
Pre-assignment
|
|||||||
Screening details |
Eighteen preterm infants (nine male, nine female) born before 31 weeks gestation and less than 7 days of postnatal age were enrolled into the study. | ||||||

Dosage and administration details |
The first dose administered was 0.1 mg kg-1 h-1 for 6 h. Successive groups received varying doses depending on the melatonin blood concentrations until mean adult physiological concentrations were achieved (approximately 46–58 pg ml-1). The dose regimens given were 0.1 mg kg-1 h-1 intravenously for 6 h, 0.1 mg kg-1 h-1 for 2 h, 0.02 mg kg-1 h-1 for 2 h, 0.01 mg kg-1 h-1 for 2 h and 0.04 mg kg-1 over 30 min.
