NCT ID NCT07482657

First seen Jun 25, 2026 · Last updated Jul 21, 2026 · Updated 4 times

Summary

This study tests an experimental oral drug called zelicapavir in 150 children aged 1 month to 3 years who have respiratory syncytial virus (RSV). The drug aims to stop the virus from multiplying and speed up recovery. Half the children will get the drug, half a placebo, and researchers will track how quickly symptoms like cough and fever go away.

What this could lead to
If successful, this could provide a new oral treatment option for young children with RSV, potentially reducing hospital stays and symptom duration.
