Antenatal magnesium sulphate to lower the risk of cerebral palsy in preterm babies

Assessment of the Role of Antenatal Magnesium Sulphate in High-Risk Preterm Patients With Cerebral Palsy: a Randomized Clinical Trial

Phase 3 Interventional Cairo University · NCT07524972

It tests whether giving pregnant people at high risk of delivering between 32 and 35 weeks an IV dose of magnesium sulphate before birth can lower their baby's chance of cerebral palsy without causing significant harm to mother or baby.

What this trial studies

This randomized, placebo-controlled Phase 3 trial enrolls women at high risk of preterm birth between 32 and 35 weeks and assigns them to receive either intravenous magnesium sulphate or an identical-volume saline placebo before delivery. Participants and outcome assessors are blinded, and all receive standard obstetric and neonatal care while maternal and neonatal safety are closely monitored during and after infusion. The main outcome is the incidence of cerebral palsy in the infant, with follow-up including neurodevelopmental assessment and recording of maternal and neonatal adverse events. The trial is conducted at Suez Canal University Hospital with allocation concealment and specified loading and maintenance infusion protocols.

Who should consider this trial

Good fit: Women with a singleton pregnancy between 32 and 35 weeks gestation who are judged to be at high risk of delivery within 24 hours, can provide informed consent, and have no contraindications to magnesium sulphate.

Not a fit: Women already receiving magnesium sulphate for preeclampsia, with contraindications to magnesium (such as myasthenia gravis or renal failure), in active second-stage labor, or with higher-order multiple pregnancies are unlikely to be eligible or to benefit from this intervention.

Why it matters

Potential benefit: If successful, the treatment could reduce the rate of cerebral palsy and improve long-term neurodevelopment for infants born preterm without adding major maternal or neonatal risks.

How similar studies have performed: Previous randomized trials and meta-analyses have generally supported antenatal magnesium sulphate for neuroprotection in preterm infants, though targeted data for the 32–35 week window in routine practice remain limited.
