Participant Flow

Open-label, 2-treatment, 2-period, 1-way crossover trial to compare the test treatment (T) to the reference treatment (R). The treatments were 1 single dose of BI 894416 following 7 days of pretreatment with rifampicin (T) and 1 single dose of BI 894416 given alone (R) with a washout period of at least 10 days between administrations of BI 894416.

All subjects were screened for eligibility prior to participation in the trial. Subjects attended a specialist site which ensured that they (the subjects) strictly met all inclusion and none of the exclusion criteria. Subjects were not to be allocated to a treatment group if any of the entry criteria were violated.

In treatment period 1, Day 1, participants were administered one oral single dose of 50 milligram (mg) BI 894416 as tablet formulation (2 tablets of 25 mg administered in the fasting state with 240 milliliter (mL) of water) (reference treatment in period 1, Reference). In treatment period 2, from Day -7 to Day -1, participants were administered one film-coated tablet of 600 mg rifampicin with 240 mL of water once daily, followed by one oral single dose of 50 mg BI 894416 as tablet formulation (2 tablets of 25 mg administered in the fasting state with 240 mL of water) on Day 1 (test treatment in period 2, Test). There was a washout period of at least 10 days between the administrations of BI 894416.
