What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.

Summary

This study tests whether a single dose of an experimental immune cell therapy called agenT-797, given alongside standard care, can lower the risk of death in adults with severe pneumonia and breathing failure. About 90 people in intensive care will receive either agenT-797 or a placebo, plus usual treatments like antibiotics and steroids. The main goal is to see if more people survive with the added therapy.

What this could mean

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

Active substance
agenT-797 (an experimental immune cell therapy given as a single intravenous infusion)
What this could lead to
If it works, this could point toward a new treatment to reduce deaths from severe pneumonia with respiratory failure.
What could go wrong
This is a small, early Phase 2 trial with only 90 participants, so results may not apply broadly. The treatment is experimental and may not improve survival or could cause side effects.
