Results Overview

0-tz refers to 0 until latest individually available cumulative fraction after drug administration. Vomit=Not applicable. Amount excreted calculated by volume multiplied with concentration of sample for respective time interval. Amount then refers to administered dose as fraction excreted in percent (dose=100%), done cumulatively. Time frames: Urine: on Day -1 or 1 -2 hours (h) before drug administration + at 0-4, 4-8, 8-12, 12-24, 24-48, 48-72, 72-96, 96-120, 120-144, 144-168, 168-192, 192-216 h after drug administration. Faeces: on Day -1 or 1 -2 hours (h) before drug administration + 0-24, 24-48, 48-72, 72-96, 96-120, 120-144, 144-168, 168-192, 192-216 h after drug administration. Thereafter, if warranted, 24 h collections for urine and faeces were to be performed every 7 days starting on Day 16, at Day 16-17, Day 23-24, Day 30-31. When the release criteria for radioactivity recovery had been met then urine/faeces sampling was stopped (earliest stop on Day 10).

Participant Flow

This is a phase I, open-label, non-randomized, single-dose, single-arm, single-period study to investigate the basic pharmacokinetics (PK) of BI 1015550 and its metabolite BI 764333 (M480), \[14C\]-radioactivity, including mass balance, excretion pathways, and metabolism following a single oral dose of BI 1015550 (C-14) administered to 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.

PRIMARY outcome

Timeframe: From Day -1 or Day 1 - 2 hours (h) before drug administration until release criteria for radioactivity recovery had been met, up to Day 30-31. See also description section.

Population: Treated set (TS): The TS set included all subjects who were entered and treated with the single dose of the trial drug. There was no occurrence of vomit among the participants therefore number of participants analyzed is zero for fevomit,0-tz.

0-tz refers to 0 until latest individually available cumulative fraction after drug administration. Vomit=Not applicable. Amount excreted calculated by volume multiplied with concentration of sample for respective time interval. Amount then refers to administered dose as fraction excreted in percent (dose=100%), done cumulatively. Time frames: Urine: on Day -1 or 1 -2 hours (h) before drug administration + at 0-4, 4-8, 8-12, 12-24, 24-48, 48-72, 72-96, 96-120, 120-144, 144-168, 168-192, 192-216 h after drug administration. Faeces: on Day -1 or 1 -2 hours (h) before drug administration + 0-24, 24-48, 48-72, 72-96, 96-120, 120-144, 144-168, 168-192, 192-216 h after drug administration. Thereafter, if warranted, 24 h collections for urine and faeces were to be performed every 7 days starting on Day 16, at Day 16-17, Day 23-24, Day 30-31. When the release criteria for radioactivity recovery had been met then urine/faeces sampling was stopped (earliest stop on Day 10).

Population: Pharmacokinetic parameter analysis set (PKS): PKS included all subjects in TS who provided at least 1 pharmacokinetics (PK) endpoint that was defined as primary or secondary and was not excluded due to protocol violation relevant to evaluation of PK or due to PK non-evaluability. Thus, a subject was included in the PKS, even if the subject contributed only 1 PK parameter value for 1 period to the statistical assessment.
