Summary

This study is open for adults with advanced cancer (solid tumours). This is a study for people for whom previous treatment was not successful. This study tests a medicine called BI 907828. BI 907828 is a so-called MDM2 inhibitor that is being developed to treat cancer. The purpose of this study is to find out whether the amount of BI 907828 in the blood is influenced by taking an OATP inhibitor or a CYP3 inhibitor. This study uses an OATP inhibitor called rifampicin and a CYP3 inhibitor called itraconazole. In clinical practice, rifampicin is used as an antibiotic. Itraconazole is used to treat fungal infections. Participants are divided into 2 groups: a rifampicin group and an itraconazole group. Every participant takes BI 907828 as a tablet every 3 weeks. This is called a cycle. * Rifampicin group: In addition to BI 907828, participants take 1 tablet of rifampicin in the second cycle. * Itraconazole group: In addition to BI 907828, participants take itraconazole tablets for 20 days starting 1 week after the second cycle begins Participants can stay in the study as long as they benefit from treatment and can tolerate it. The doctors take blood samples from the participants to compare the amount of BI 907828 in the blood when it is taken alone and when participants also take rifampicin. Doctors also regularly check participants' health and take note of any unwanted effects.
