Summary

This completed Phase 1 study looked at how healthy men process and eliminate the antibiotic zidebactam. Eight participants received a single dose with a radioactive tracer to track the drug in urine and feces. The goal was to understand how the drug is broken down and how quickly it leaves the body, which helps guide future dosing studies.

What this could mean

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

Active substance
zidebactam (an antibiotic)
What this could lead to
If successful, this study will clarify how zidebactam is broken down and removed from the body, helping to design better dosing for future patients.
What could go wrong
This is a very early, small study in just 8 healthy men. It does not test whether the drug works against infections, and results may not apply to women or sick people.
