Melatonin and Perinatal Outcomes in MVM-Related Fetal Growth Restriction (MIMVMFGR)
China240 participantsStarted 2023-01-01
Plain-language summary
The goal of this clinical trial is to evaluate the efficacy and safety of melatonin in the treatment of early-onset severe maternal vascular malperfusion-related fetal growth restriction (MVM-FGR), and to determine its effects on fetal growth and perinatal outcomes. The study will enroll pregnant women with singleton pregnancies diagnosed with severe MVM-FGR between 24+0 and 31+6 weeks of gestation.
The main questions it aims to answer are:
* Whether melatonin treatment can reduce the incidence of a composite adverse neonatal outcome, including neonatal death and severe neonatal complications.
* Whether melatonin treatment can improve pregnancy and neonatal outcomes, including the interval from treatment initiation to delivery, gestational age at delivery, fetal growth trajectory throughout pregnancy (Z-score slope over time estimated using linear mixed models), neonatal birthweight, Apgar scores, neonatal complications (such as respiratory distress syndrome), maternal adverse events (such as hypertensive disorders of pregnancy), and placental pathological findings.
Researchers will compare participants receiving a placebo (one capsule taken at bedtime, identical in appearance and size to melatonin) with those receiving melatonin to determine whether melatonin improves these maternal and neonatal outcomes.
Participants will:
• Take melatonin 10 mg orally once nightly at bedtime.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
