A Study in Healthy Men to Test Whether Itraconazole Influences the Amount of BI 1584862 in the Blood

Effect of Itraconazole on the Pharmacokinetics of a Single Oral Dose of BI 1584862 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 1584862 in plasma when given as single dose together with multiple doses of itraconazole (Test, T) as compared to BI 1584862 when given alone as oral single dose (Reference, R).

Description

Inclusion Criteria:

1. 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 (BP), pulse rate (PR)), 12-lead electrocardiogram (ECG), and clinical laboratory tests
2. Age of 18 to 50 years (inclusive)
3. Body mass index (BMI) of 18.5 to 29.9 kg/m2 (inclusive)
4. Signed and dated written informed consent in accordance with ICH-GCP and local legislation prior to admission to the trial

Exclusion Criteria:

1. Any finding in the medical examination (including BP, PR or ECG) deviating from normal and assessed as clinically relevant by the investigator
2. Repeated measurement of systolic blood pressure outside the range of 90 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
3. Any laboratory value outside the reference range that the investigator considers to be of clinical relevance
4. Any evidence of a concomitant disease assessed as clinically relevant by the investigator
5. Gastrointestinal, hepatic, renal, respiratory, cardiovascular, metabolic, immunological or hormonal disorders
6. Cholecystectomy or other surgery of the gastrointestinal tract that could interfere with the pharmacokinetics of the trial medication (except appendectomy or simple hernia repair)
7. Diseases of the central nervous system (including but not limited to any kind of seizures or stroke), and other relevant neurological or psychiatric disorders
8. History of relevant orthostatic hypotension, fainting spells, or blackouts Further exclusion criteria apply

Intervention / Treatment

Experimental: BI 1584862 (R), then BI 1584862 + itraconazole (T); Reference treatment (R): healthy male subjects were administered one single dose of BI 1584862 as tablets orally with 240 milliliter (mL) of water after an overnight fast of at least 10 hours (h). Test treatment (T): healthy male subjects were administered one single dose of BI 1584862 as tablets orally with 240 mL of water after an overnight fast of at least 10 h. Additionally, subjects were administered one daily dose of 200 milligram (mg) itraconazole as an oral solution after an overnight fast of at least 9 h for several consecutive days. The two administrations of BI 1584862 were separated by a washout period.

Drug: BI 1584862; One dose with 240 mL of water after an overnight fast of at least 10 h; Drug: Itraconazole; 200 mg daily after an overnight fast of at least 9 h for several consecutive days

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Area Under the Concentration-time Curve of BI 1584862 in Plasma Over the Time Interval From 0 Extrapolated to Infinity (AUC0-∞)	Area under the concentration-time curve of BI 1584862 in plasma over the time interval from 0 extrapolated to infinity (AUC0-∞) is reported. Geometric least square mean (adjusted geometric mean) and adjusted geometric standard error were calculated using an analysis of variance (ANOVA) model on the logarithmic scale. The pharmacokinetic (PK) endpoints were log-transformed (natural logarithm) prior to fitting the ANOVA model, which included effects accounting for the following sources of variation: 'subjects' was considered as a random effect, 'treatment' as a fixed effect. These quantities were then back-transformed to the original scale.	Within 3 to 4 h before and up to 3 days after BI 1584862 administration.
Maximum Measured Concentration of BI 1584862 in Plasma (Cmax)	Maximum measured concentration of BI 1584862 in plasma (Cmax) is reported. Geometric least square mean (adjusted geometric mean) and adjusted geometric standard error were calculated using an ANOVA model on the logarithmic scale. The PK endpoints were log-transformed (natural logarithm) prior to fitting the ANOVA model, which included effects accounting for the following sources of variation: 'subjects' was considered as a random effect, 'treatment' as a fixed effect. These quantities were then back-transformed to the original scale.	Within 3 to 4 h before and up to 3 days after BI 1584862 administration.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Area Under the Concentration-time Curve of BI 1584862 in Plasma Over the Time Interval From 0 to the Last Quantifiable Data Point (AUC0-tz)	Area under the concentration-time curve of BI 1584862 in plasma over the time interval from 0 to the last quantifiable data point (AUC0-tz) is reported. Geometric least square mean (adjusted geometric mean) and adjusted geometric standard error were calculated using an ANOVA model on the logarithmic scale. The PK endpoints were log-transformed (natural logarithm) prior to fitting the ANOVA model, which included effects accounting for the following sources of variation: 'subjects' was considered as a random effect, 'treatment' as a fixed effect. These quantities were then back-transformed to the original scale.	Within 3 to 4 h before and up to 3 days after BI 1584862 administration.

IPD Plan Description

Clinical studies sponsored by Boehringer Ingelheim, phases I to IV, interventional and non-interventional, are in scope for sharing of the raw clinical study data and clinical study documents. Exceptions might apply, e.g. studies in products where Boehringer Ingelheim is not the license holder; studies regarding pharmaceutical formulations and associated analytical methods, and studies pertinent to pharmacokinetics using human biomaterials; studies conducted in a single center or targeting rare diseases (in case of low number of patients and therefore limitations with anonymization).
