A Study to Test Different Doses of BI 3011441 in Japanese People With Different Types of Advanced Cancer (NRAS/KRAS Mutation Positive)

This study is open to Japanese adults with different types of advanced cancer that are positive for NRAS/KRAS mutations. This is a study in people for whom previous treatment was not successful or no standard treatment exists. The purpose of this study is to find the highest dose of BI 3011441 that Japanese people with advanced cancer can tolerate. BI 3011441 is a medicine that may turn off a signal by NRAS/KRAS that makes tumours grow. Participants take BI 3011441 as capsules once a day. Participants can stay in the study as long as they benefit from treatment and can tolerate it. The doctors collect information on any health problems of the participants.
