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

May 7, 2026 updated by: Boehringer Ingelheim

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).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
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-∞)
Time Frame: Within 3 to 4 h before and up to 3 days after BI 1584862 administration.

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)
Time Frame: Within 3 to 4 h before and up to 3 days after BI 1584862 administration.
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

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
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)
Time Frame: 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).
