Summary
This study is open to adults with borderline personality disorder (BPD) and with attention deficit/ hyperactivity disorder (ADHD). The purpose of this study is to find out how a medicine called BI 3031185 is tolerated by people with BPD or ADHD. Participants with BPD with ADHD are in separate cohorts. Participants from each cohort are put into 2 groups of equal size randomly, which means by chance. Group 1 takes a single dose of BI 3031185 and Group 2 takes placebo. After a 2-week break, Group 1 takes placebo and Group 2 takes a single dose of BI 3031185. Participants take BI 3031185 and placebo as tablets. Participants are in the study for about 1 to 2 months. They visit the study site 6 times and have 3 phone or video call visits. For 2 of the visits, participants stay overnight at the study site for 2 nights. During all the visits, doctors check participants' health and take note of any unwanted effects.

- Positive drug screen. Participants with positive cannabis drug tests can be included if they do not meet criteria for moderate or severe cannabis use disorder and the investigator determines that use will not be an impediment to trial participation or accurate data collection
- Concomitant use of psychotropic medication except for the ones below. All other psychotropic medications must be washed out at least 30 days or 5 Half-life time (t1/2) (whichever is longer) before the start of Visit 2 (Day -1)

- A single second-generation antipsychotic at a low dose that has been stable in dose and frequency for \>3 months prior to randomisation (low dose = 1 thorazine dose equivalent or less, which translates to ≤2 mg/day for risperidone, 5 mg/day for olanzapine, 75 mg/day for quetiapine, 60 mg/day for ziprasidone, and 7.5 mg/day for aripiprazole)
- A single sleep medication given as a nightly scheduled medication (not pro re nata) stable in agent and dose for \>3 months prior to screening. Allowed sleep medications include: non-benzodiazepine Z sleep medications, antihistamines, melatonin, trazodone, and doxepin
