NCT ID NCT07308652
First seen Jun 27, 2026 · Last updated Jul 07, 2026 · Updated 2 times
Summary
This completed Phase 1 study in 14 healthy men tested whether taking multiple doses of itraconazole changes the amount of BI 764198 in the blood after a single dose. Participants took BI 764198 alone and then again with itraconazole to compare drug levels. The goal is to understand how these medicines interact, which is important for people who may need both.
