Study Summary

This is a study in adults with advanced cancer (solid tumours) in whom previous treatment was not successful. The study tests 2 medicines called BI 1387446 and BI 754091. Both medicines may help the immune system fight cancer. In this study, BI 1387446 is given to humans for the first time. The purpose of this study is to find out the highest dose of BI 1387446 alone and in combination with BI 754091 the participants can tolerate. BI 1387446 is injected directly into the tumour. Participants get BI 1387446 injections every week at the beginning and then every 3 weeks. Some participants get BI 754091 in addition to BI 1387446. BI 754091 is given as an infusion into a vein every 3 weeks. As long as they benefit from treatment and can tolerate it, participants can stay in the study for up to 2 years and 8 months. During this time, they visit the study site regularly. At these visit, doctors record any unwanted effects. The doctors also regularly check participants' health.

Primary Outcome

The MTD in each arm is defined as the highest dose that is expected to cause less than 25% risk of the true DLT rate being above or equal to 33% during the MTD evaluation period. Estimation of the MTD will be based upon the estimation of the posterior probability of the incidence of DLT in toxicity categories during the MTD evaluation period for all evaluable participants. The MTD evaluation period is defined as the time from the first administration of any trial medication to the start of the
