Participant Flow

A non-randomised, open-label, single period, single arm trial to determine the absolute oral bioavailability of BI 1015550 in healthy male subjects.

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.

Measure
18 mg BI 1015550 / 100 μg BI 1015550 (C-14)
One film-coated tablet of 18 milligram (mg) BI 1015550 was administered as single oral dose with 240 milliliter of water after an overnight fast of at least 10 hours on Day 1 as test treatment (T). 100 microgram (μg) BI 1015550 (C-14) solution (consisting of 90 μg unlabelled BI 1015550 mixed with 10 μg labelled \[14C\]-BI 1015550 in 10 mL intravenous solution with a final concentration of 10 μg BI 1015550 (C-14)/mL) was administered as single intravenous infusion over 15 minutes on Day 1 as reference treatment (R). The radioactive dose per infusion was \~40 kilobecquerel (kBq).

PRIMARY outcome

Timeframe: Between waking up and still prior to drug intake and 0.5*, 0.75*, 1*, 1.5*, 1.58±, 1.67±, 1.75, 2, 2.5±, 3, 4, 5±, 6, 7±, 8, 12, 16, 24, 36, 48, 72, 120, 168, 216± hours after intake of oral BI 1015550 tablet, *for T treatment, ±only for R treatment.

Population: Pharmacokinetic (PK) set (PKS): All subjects in the treated set (TS) who provided at least one PK endpoint that was not excluded due to a protocol deviation relevant to the evaluation of PK or due to non-evaluability.

Dose normalized AUC0-inf of \[14C\]-BI 1015550 after intravenous (i.v.) administration and AUC0-inf of BI 1015550 after oral (p.o.) administration are reported. The analysis was performed only on the pharmacologically active R-enantiomer.
