Summary

This study is open to adults with overweight or obesity who are otherwise healthy. People can join the study if they have a body mass index of 27 to 39.9 kg/m2 and a body weight over 70 kg. The purpose of this study is to find out whether taking multiple doses of BI 456906 influences the amount of bupropion, caffeine, and midazolam in the blood.

The study has 2 treatment periods. In Period 1, participants take 1 dose each of midazolam, caffeine, and bupropion as tablets or oral solution on separate days. In Period 2, participants get BI 456906 as an injection under the skin once a week. At 2 selected timepoints in Period 2, participants also take midazolam, caffeine and bupropion as tablets or oral solution on separate days.

Participants are in the study for about 13 months. They visit the study site up to 45 times. At 3 of those visits, participants stay for 5 or 6 days at the study site. During the visits, doctors collect information about participants' health and take blood samples from the participants. They compare the amounts of midazolam, caffeine, and bupropion in the blood in Period 2 with the amounts in Period 1. Doctors also regularly check participants' health and take note of any unwanted effects.
