A Study in Healthy Men to Test How Zongertinib is Taken up in the Body When Taken With or Without Food

Relative Bioavailability of BI 1810631 Following Oral Administration Under Fed and Fasted Conditions in Healthy Male Subjects (an Open-label, Randomised, Single-dose, Two-way Crossover Trial)

The main objective of this trial is to investigate the relative bioavailability of a single dose of BI 1810631 intended commercial formulation (iCF) under fed (Test treatment, T) and fasted (Reference treatment, R) conditions.

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 55 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 Blood pressure (BP), pulse rate (PR) or electrocardiogram (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)

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: BI 1810631 (iCF) fed state (Reference, R) then fasting state (Test, T); Period 1: Participants received a single oral dose of 240 milligram (mg) Zongertinib as film coated tablets (4x 60 mg tablet) following a high fat/high calorie meal.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Area Under the Concentration-time Curve of Zongertinib in Plasma Over the Time Interval From 0 to the Last Quantifiable Data Point (AUC0-tz)	Area under the concentration-time curve of Zongertinib in plasma over the time interval from 0 to the last quantifiable data point (AUC0-tz). Geometric least square mean (adjusted geometric mean) and 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. These quantities will then be back-transformed to the original scale to provide the point estimate and 90% confidence intervals (CIs) for each endpoint.	Within 3 hours before Zongertinib administration, and 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120, 144, and 168 hours following administration.
Maximum Measured Concentration of the Zongertinib in Plasma (Cmax)	Maximum measured concentration of Zongertinib in plasma (Cmax). Geometric least square mean (adjusted geometric mean) and 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. These quantities will then be back-transformed to the original scale to provide the point estimate and 90% confidence intervals (CIs) for each endpoint.	Within 3 hours before Zongertinib administration, and 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120, 144, and 168 hours following administration.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Area Under the Concentration-time Curve of Zongertinib in Plasma Over the Time Interval From 0 Extrapolated to Infinity (AUC0-∞)	Area under the concentration-time curve of Zongertinib in plasma over the time interval from 0 extrapolated to infinity (AUC0-∞). Geometric least square mean (adjusted geometric mean) and 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. These quantities will then be back-transformed to the original scale to provide the point estimate and 90% confidence intervals (CIs) for each endpoint.	Within 3 hours before Zongertinib administration, and 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120, 144, and 168 hours following 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).
