First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time

Summary

This completed Phase 1 trial studied 14 healthy men to see how itraconazole, a common antifungal, affects the levels of a new experimental drug called BI 706321 in the body. Participants took BI 706321 alone and then again after several days of itraconazole. The goal was to measure how the body absorbs and processes the drug, which helps guide future dosing recommendations.
