NCT ID NCT07176728
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage study tested a new drug called BAY 3389934 in 16 healthy Japanese adults to see if it is safe and how the body handles it. The drug is being developed to treat a serious blood clotting condition that can happen with severe infections (sepsis). Participants received either the drug or a placebo through an IV, and researchers monitored for side effects and measured drug levels in the blood.
