New drug interaction study completed in healthy men

This study looked at how a new drug called BI 425809 changes the way the body processes four common medications (midazolam, warfarin, omeprazole, and digoxin) in 13 healthy men. The goal was to see if BI 425809 affects how these drugs are broken down, which helps doctors understand safe dosing. Participants took the drugs alone and then with BI 425809, and their blood levels were measured. This was a Phase 1 trial, meaning it focused on safety and drug interactions, not treatment.
