First seen Jun 27, 2026 · Last updated Aug 20, 2026 · Updated 3 times
Summary
This early-stage trial investigates the safety and tolerability of a new drug called BI 3031185 in healthy Japanese men, given as single or multiple doses. It also examines whether multiple doses of BI 3031185 affect how the body processes a common oral contraceptive (YAZ®) in healthy Japanese women. The study aims to gather crucial safety data and understand potential drug interactions before moving to larger trials.
