Details and patient eligibility

About

In order to assess the potential impact of steady state BI 425809 on CYP3A clinically, the effect of BI 425809 on the midazolam pharmacokinetics will be evaluated. Midazolam is a recommended substrate of CYP3A4.

Enrollment: 15 patients

Sex: Male

Ages: 18 to 55 years old

Volunteers: Accepts Healthy Volunteers

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 (BP), pulse rate (PR)), 12-lead electrocardiogram (ECG), and clinical laboratory tests

• Any finding in the medical examination (including BP, PR or ECG) deviating from normal and assessed as clinically relevant by the investigator
• Repeated measurement of systolic blood pressure outside the range of 90 to 140 mmHg, diastolic blood pressure outside the range of 50 to 90 millimetre of mercury (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)

15 participants in 1 patient group

midazolam alone (Reference (R)) / midazolam + iclepertin (BI 425809) (Test (T))

Experimental group

Description:

All participants were orally administered a single dose of 2 milligrams (mg) midazolam solution alone on Day 1 of Period 1 (reference treatment). All participants were also orally administered one film-coated tablet of 10 mg iclepertin (BI 425809) once daily over 21 days (from Day -20 until Day 1 of Period 2) and 2 mg midazolam oral solution concomitantly with a film-coated tablet of 10 mg iclepertin on Day 1 of Period 2 (test treatment). There was a washout phase of at least 24 hours between the administration of midazolam in Period 1 and the first iclepertin administration in Period 2. The treatments were to be given under fasting conditions with 240 milliLiter (mL) of water.

Treatment:

Drug: midazolam

Drug: iclepertin (BI 425809)
