ClinConnect Summary

The SNACS trial is studying whether a lower dose of a medication called Celestone, given to pregnant people at risk of preterm birth, is as effective as the standard higher dose. Celestone is a type of antenatal corticosteroid that helps improve the development of a baby's lungs, which can reduce the chances of serious health problems in preterm infants. In this trial, researchers are looking at whether giving 12 mg (instead of the usual 24 mg) can still provide the same benefits.

To participate in this trial, pregnant individuals between the ages of 18 and 55 who are at risk of delivering their baby early and have received only one dose of Celestone within the last 24 hours may be eligible. Participants will need to provide informed consent before joining the study. This trial is currently recruiting, and it’s important to know that certain health conditions or previous participation in the trial may disqualify someone from taking part. If you or someone you know fits the criteria and is interested, this study could contribute to improving care for preterm births.
