RSV drug trial for kids under 5 halted early – only 4 children enrolled

NCT ID NCT06784973

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested an oral antiviral drug called obeldesivir in children from birth to under 5 years old who had RSV infection. The goal was to see if the drug is safe and helps reduce symptoms faster. However, the trial was stopped early and only enrolled 4 participants, so the results are very limited.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

obeldesivir (an antiviral drug taken by mouth)

What this could lead to

If it works, this could provide a treatment to help young children recover faster from RSV infection.

What could go wrong

The trial was terminated early with only 4 participants, so there is very little data to know if it is safe or effective. It may not work or could have side effects.
