Healthy men help uncover drug interactions in Early-Stage trial

This early-stage study looked at how taking multiple doses of an experimental drug (BI 1015550) changes the way the body handles two approved lung medications (nintedanib and pirfenidone). Fourteen healthy men received the drugs in a fixed order, and researchers measured drug levels in their blood. The goal was to see if BI 1015550 speeds up or slows down the breakdown of these medicines, which helps guide future dosing in patients.
