Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
4mg prolonged release melatonin oral tablets twice daily. Treatment will occur as soon as the diagnosis of intrauterine growth restriction is made and the patient has been enrolled to this study until birth. The overall duration of treatment will vary due to the nature of intrauterine growth restriction.
Intervention code [1] 285418 0
Treatment: Drugs
Comparator / control treatment
No treatment. An historical control group will be used as a comparator. These women/pregnancies have been studied in 2011 and 2012. The historical group are women with healthy pregnancies and women with pregnancies affected by intrauterine growth restriction who have not received melatonin treatment, both groups of women have been treated at Monash Medical Centre. Data collected from these patients are derived from medical histories (clinical data regarding pregnancy and outcome) and from Monash Medical Centre maternal and umbilical cord blood, amniotic fluid and placental samples assessed for levels of oxidative stress (malondialdehyde and 8-isoprostane).

Timepoint [3] 298756 0
Birth
Secondary outcome [4] 298757 0
Gestation at birth. This is calculated based using the last menstrual period in combination with data derived from ultrasound studies.
Timepoint [4] 298757 0
Birth
Secondary outcome [5] 298758 0
Composite neonatal outcome (admission to NICU, duration of admission, need and duration of respiratory support, intraventricular haemorrhage, necrotising enterocolitis, abnormal neurological assessment, mortality before discharge). This composite neonatal outcome will be measured by collecting medical record data after clinical assessments.
Timepoint [5] 298758 0
Birth to discharge from hospital

Treatment
Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation concealment procedures are not applicable to this study as it is a small non-randomized pilot study.

The study population will consist of pregnant women undergoing prenatal care at Southern Health: Monash Medical Centre or Jessie McPherson Private Hospital, who meet the study's inclusion criteria. Potential participants will be identified through the antenatal clinic and the maternal fetal medicine unit at Monash Medical Centre. If considered eligible, the woman will be approached by the researcher, introduced to the trial, given the patient information sheet, counselled and invited to participate. Potential participants will be informed of the aims, methods and any reasonably anticipated benefits or potential hazards of the study. Subjects will be informed that their participation is voluntary and that they may withdraw consent to participate at any time during the study and that choosing not to participate will, in no way affect their care. Encouragement will be given to take as much time as necessary to consider participation and discuss their involvement with their partner and family. The women are informed that the researchers and other medical personnel are available to answer all their questions. Women are recruited to the study once written informed consent is obtained.

Summary
Brief summary
Intrauterine growth restriction is the term used to describe a condition where an unborn baby does not reach its optimum size. In the short and long term, intrauterine growth restricted babies have a higher risk of serious disease and even death. It is well established that very low levels of oxygen in the baby's blood can harm the baby's health through a state known as oxidative stress. Currently, there is no established treatment available to treat intrauterine growth restriction or its complications. In experimental animal studies however, the naturally occuring hormone, melatonin, has been shown to significantly reduce oxidative stress and improve health of the unborn babies that have suffered from intrauterine growth restriction. This study aims to find out if the use melatonin twice per day throughout pregnancies affected by intrauterine growth restriction will lower the level of oxidative stress experienced by the unborn baby. If this is the case melatonin may help protect the unborn baby from damage caused by oxidative stress, this will be studied in a separate future study.
