Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is open to people between 18 and 65 years of age with opioid use disorder. Opioid use disorder is also called opioid addiction or opioid dependence. People can join the study if they currently take a medicine called buprenorphine. People with opioid dependence can act on impulse, which can lead to risky behaviours. The purpose of this study is to find out whether a medicine called BI 1356225 improves impulse control in people with opioid dependence.

Participants are put into 2 groups by chance. One group takes BI 1356225 tablets and the other group takes placebo tablets. Placebo tablets look like BI 1356225 tablets but do not contain any medicine. Participants take a tablet once a day for 8 days. All participants also continue taking buprenorphine.

Participants are in the study for up to 6 weeks. During this time, they visit the study site 3 times. At visit 2, participants stay at the study site for 9 nights. Doctors test participants' impulsivity using tasks or games on a computer and questionnaires. The results are compared between the 2 groups to see whether the treatment works. The doctors also regularly check participants' health and take note of any unwanted effects.

2. Meet current diagnostic and statistical manual of mental disorders, fifth edition (DSM-5) criteria for opioid use disorder, of at least moderate severity within the 12 months prior to screening
3. Currently engaged in medications for opioid use disorder (MOUD) treatment with one of the following regimens:

1. buprenorphine/naloxone sublingual film total daily dose ranging from 8 mg/2 mg to 24 mg/6 mg for at least 2 weeks at screening OR
2. buprenorphine/naloxone sublingual tablet from 5.7 mg/1.4 mg to 17.1 mg/4.3 mg total daily dose for at least 2 weeks at screening OR
3. buprenorphine sublingual tablet from 8 mg to 24 mg total daily dose for at least 2 weeks at screening OR
4. on depot injectable buprenorphine for at least 5 weeks at screening, with at least 1 week since last depot buprenorphine injection
4. Have a current MOUD prescription in accordance with inclusion criterion 4 and a positive urine drug screen for buprenorphine during screening and upon presenting for randomization to document buprenorphine use
5. Willingness to abstain from using alcohol for 24 hours (h) and all other drugs of abuse for 72 h prior to Day 1 and through discharge from the trial site on Day 9
6. Women of child-bearing potential must be able and willing, as confirmed by the investigator, to use highly effective methods of contraception
