Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Melatonin

Experimental: Melatonin - Women with IUGR will take 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.

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.
