A Study in Healthy Men to Test How Itraconazole Influences the Amount of Zongertinib (BI 1810631) in the Blood

September 3, 2025 updated by: Boehringer Ingelheim

The Effect of Multiple Doses of Itraconazole on the Pharmacokinetics of a Single Oral Dose of BI 1810631 in Healthy Male Subjects (an Open-label, Two-period, Fixed-sequence Trial)

The main objective of this trial is to investigate the effect of multiple doses of the strong CYP3A inhibitor and recommended P-glycoprotein (P-gp) inhibitor itraconazole on the pharmacokinetics of a single dose of zongertinib in plasma following oral administration.

Description

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
  • Age of 18 to 50 years (inclusive)
  • Body mass index (BMI) of 18.5 to 29.9 kg/m2 (inclusive)
  • Signed and dated written informed consent in accordance with International Council for Harmonisation-Good Clinical Practice (ICH-GCP) and local legislation prior to admission to the trial

Exclusion Criteria:

  • 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 millimetre(s) of mercury (mmHg), diastolic blood pressure outside the range of 50 to 90 mmHg, or pulse rate outside the range of 50 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 Further exclusion criteria apply.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Zongertinib alone (R) / Zongertinib + itraconazole (T)

Treatment Period 1: a single oral dose of 15 milligrams (mg) zongertinib, film-coated tablet, was administered once on Day 1 (Day 1, Period 1, Visit 2), as reference treatment R.

Treatment Period 2: a single oral solution of 200 mg (10 mg/mL in a 20 milliliter (mL) solution) itraconazole was administered once daily over 14 days ([total: 14 doses], from Day -3 to Day 11, Period 2). On Day 1 (Day 1, Period 2, Visit 3), 4th day of itraconazole treatment, a single oral dose of 15 mg zongertinib was administered 1 hour (h) after itraconazole administration as test treatment T.

The two administrations of zongertinib were separated by a washout interval of at least 14 days.

Zongertinib and itraconazole were orally administered with 240 mL of water after an overnight fast of at least 10 h for zongertinib and 9 h for itraconazole.

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).
