COVID antibody drug tested in kids – but study stopped early
NCT ID NCT05092581
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a single dose of casirivimab+imdevimab (REGN-COV2) in children hospitalized with COVID-19. The goal was to see how the drug behaves in the body and whether it is safe. However, the study was terminated early and only enrolled 2 participants, so we have very little information from it.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- casirivimab+imdevimab (REGN-COV2, a combination of two monoclonal antibodies)
- What this could lead to
- If successful, this could provide a treatment option for hospitalized children with COVID-19.
- What could go wrong
- This was a very early (Phase 1) study that was terminated after enrolling only 2 participants, so results are extremely limited and may not be reliable.
