Read our Asthma research guide →Phase 4 — The treatment has already been approved. Researchers are tracking how it works in a large number of people over time.
This trial is testing whether dexamethasone, a steroid medication, can help prevent asthma from developing in young children who experience their first serious wheezing episode caused by a common cold virus called rhinovirus. Researchers believe that treating the inflammation during this first episode may reduce the risk that a child will develop asthma later in life. The study will enroll about 280 children across hospitals in Norway, Finland, and Sweden.
Asthma often starts in early childhood, and children who have wheezing caused by rhinovirus are at high risk of developing asthma. Current prevention strategies have not been very effective, so researchers want to test whether treating the inflammation early with this medication might prevent asthma from developing in the first place.

Your child would receive the steroid medication dexamethasone while hospitalized for their wheezing episode as part of their acute care. After discharge, you would return for follow-up visits so researchers can track whether your child develops asthma symptoms over time and compare outcomes between children who received the medication and those who received standard care. The study will follow your child's health to see if this early treatment reduces the chance of asthma developing.
