This Study in Healthy Men Tests How Itraconazole Influences the Amount of BI 1015550 in the Blood

November 14, 2025 updated by: Boehringer Ingelheim

Relative Bioavailability of a Single Oral Dose of BI 1015550 When Administered Alone or in Combination With Multiple Oral Doses of Itraconazole in Healthy Male Subjects

The primary objective of this trial is to investigate whether and to what extent co-administration of multiple doses of itraconazole affect single dose pharmacokinetics of BI1015550, i.e. to compare the relative bioavailability of 6 mg BI 1015550 when given alone (reference, treatment R) to the relative bioavailability of 6 mg of BI 1015550 given on the 4th day of a 12-day-treatment with itraconazole (test, treatment T) following oral administration in healthy male subjects.

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 1015550 alone (R) / itraconazole + BI 1015550 (T)
Participants were administered single dose of BI 1015550 6 milligram (mg) tablet orally with 240 milliLitre (mL) of water after an overnight fast of at least 10 hours on Day 1 of Visit 2. Again participants were administered itraconazole plus BI 1015550; participants received 12 days of itraconazole treatment (200 mg itraconazole solution given orally once daily with 240 mL of water after an overnight fast of at least 9 h) from Day -3 to Day 9 of Visit 3 combined with a single dose of 6 mg BI 1015550 on the fourth day (Day 1) of the itraconazole treatment (1 hour after the itraconazole administration). The BI 1015550 single doses of treatments R and T were separated by a wash-out period of at least 10 days.
