A Study in Healthy Men to Test How Itraconazole Influences the Amount of BI 474121 in the Blood

Effect of Itraconazole on the Pharmacokinetics of a Single Oral Dose of BI 474121 in Healthy Male Subjects (an Open-label, Two-period Fixed Sequence Design Study)

The main objective of this trial is to investigate the effect on the exposure of BI 474121 in plasma when given as oral single dose together with multiple oral doses of itraconazole (Test, T) as compared to when given alone as oral single dose (Reference, R).

Description

Inclusion Criteria:

• Repeated measurement of systolic blood pressure outside the range of 100 to 140 mmHg, diastolic blood pressure outside the range of 50 to 90 mmHg, or pulse rate outside the range of 45 to 90 bpm
• Any laboratory value outside the reference range that the investigator considers to be of clinical relevance
• Any evidence of a concomitant disease assessed as clinically relevant by the investigator
• Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders
• Cholecystectomy or other surgery of the gastrointestinal tract that could interfere with the pharmacokinetics of the trial medication (except appendectomy or simple hernia repair)

Participant Group / Arm

Intervention / Treatment

Experimental: Sequence: BI 474121 alone (Reference) - Itraconazole + BI 474121 (Test); Period 1: Reference (R) treatment: Healthy subjects received a single dose of 0.5 milligram (Powder for oral solution, 0.5 milligram (mg)/milliliter (mL) formulation) BI 474121 on day 1 of period 1. Period 2: Test (T) treatment: Healthy subjects received a daily dose of 200 milligram (oral solution, 10 mg/mL) Itraconazole for 14 days (days -3 - 11 of period 2) and a single dose of 0.5 milligram (Powder for oral solution, 0.5 milligram mg/mL formulation) BI 474121 on day 1 of period 2. BI 474121 administrations in treatment R and treatment T were separated by a wash-out period of at least 10 days. Administration of trial medication with 240 mL of water was performed after subjects had fasted overnight; fasting was to start no later than 10 hours before the scheduled dosing of BI 474121 or 9 hours before itraconazole administration.

Drug: Itraconazole; Itraconazole oral solution; Drug: BI 474121; BI 474121 oral solution

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Area Under the Concentration-time Curve of BI 474121 in Plasma Over the Time Interval From 0 Extrapolated to Infinity (AUC0-∞)	Area under the concentration-time curve of BI 474121 in plasma over the time interval from 0 extrapolated to infinity (AUC0-∞). Model used was an analysis of variance (ANOVA) model on the logarithmic scale. Data were log-transformed (natural logarithm) prior to fitting the ANOVA model. The effect 'subjects' was considered as random effect, whereas 'treatment' was considered as fixed effect.	Within 3 hours before and 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 4, 6, 7, 8, 10, 12, 24, 34, 46, 70, 94, 118, 142 hours after BI 474121 administration in each period. In addition at 166, 190, 214, 238, 262 hours after BI 474121 administration in period 2.
Maximum Measured Concentration of BI 474121 in Plasma (Cmax)	Maximum measured concentration of BI 474121 in plasma (Cmax). Model used was an analysis of variance (ANOVA) model on the logarithmic scale. Data were log-transformed (natural logarithm) prior to fitting the ANOVA model. The effect 'subjects' was considered as random effect, whereas 'treatment' was considered as fixed effect.
