A Study in Healthy Men to Test How Itraconazole Influences the Amount of BI 1815368 in the Blood

The main objective of this trial is to investigate the effect on the exposure of BI 1815368 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).

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Healthy male subjects according to the assessment of the investigator, as based on a complete medical history including a physical examination, vital signs (blood pressure, pulse rate), 12-lead electrocardiogram, and clinical laboratory tests
  • Age of 18 to 55 years (inclusive)
  • Body mass index (BMI) of 18.5 to 29.9 kilograms per square meter (kg/m^2) (inclusive)
  • Signed and dated written informed consent in accordance with International Conference of Harmonization-Good Clinical Practice (ICH-GCP) and local legislation prior to admission to the trial

Exclusion criteria

  • Any finding in the medical examination (including blood pressure, pulse rate or electrocardiogram) deviating from normal and assessed as clinically relevant by the investigator
  • Repeated measurement of systolic blood pressure outside the range of 90 to 140 millimeter of mercury (mmHg), diastolic blood pressure outside the range of 50 to 90 mmHg, or pulse rate outside the range of 45 to 90 beats per minute (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)
  • Diseases of the central nervous system (including but not limited to any kind of seizures or stroke), and other relevant neurological or psychiatric disorders
  • History of relevant orthostatic hypotension, fainting spells, or blackouts
  • Relevant chronic or acute infections

Further exclusion criteria may apply.

Primary outcomes

  1. Area Under the Concentration-time Curve of BI 1815368 Over the Time Interval From 0 Extrapolated to Infinity (AUC0-∞)

    Time frame: Within 3 hours prior to and 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 12, 24, 34, 47, and 71 hours for both periods, and additionally at 95, 119 and 143 hours for Period 2 after BI 1815368 administration.

    Area under the concentration-time curve of BI 1815368 in plasma over the time interval from 0 extrapolated to infinity (AUC0-∞) is reported. Geometric least squares mean (adjusted geometric mean) and adjusted geometric standard error were calculated using an analysis of variance model (ANOVA) on the logarithmic scale.

    The pharmacokinetic (PK) endpoints were log-transformed (natural logarithm) prior to fitting the ANOVA model. The model included 'subjects' as a random effect and treatment as a fixed effect. These quantities were then back transformed to the original scale to provide the point estimate and 90% confidence intervals (CIs) for each endpoint.

  2. Maximum Measured Concentration of BI 1815368 in Plasma (Cmax)

    Time frame: Within 3 hours prior to and 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 12, 24, 34, 47, and 71 hours for both periods, and additionally at 95, 119 and 143 hours for Period 2 after BI 1815368 administration.

Secondary outcomes

  1. Area Under the Concentration-time Curve of BI 1815368 in Plasma Over the Time Interval From 0 to the Last Quantifiable Data Point (AUC0-tz)

    Time frame: Within 3 hours prior to and 0.25, 0.5, 0.75, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 12, 24, 34, 47, and 71 hours for both periods, and additionally at 95, 119 and 143 hours for Period 2 after BI 1815368 administration.
