Which steroid works best for severe pneumonia? major trial aims to find out
NCT ID NCT06892197
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compares two common steroids, hydrocortisone and prednisolone, in 1,600 adults hospitalized with severe community-acquired pneumonia. The goal is to see which one reduces deaths within 30 days. Participants are randomly assigned to one of the two treatments.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- corticosteroids (hydrocortisone and prednisolone)
- What this could lead to
- If it works, this could identify which steroid is better for treating severe pneumonia and potentially lower death rates.
- What could go wrong
- This is a phase 4 trial, so both drugs are already used; the difference may be small. Side effects like infections and high blood sugar are possible.
