Brief summary

The main objective of this trial is to investigate the effect of multiple oral doses of the strong CYP3A inducer carbamazepine on the pharmacokinetics of a single dose of BI 1810631 in plasma.

Interventions

Participants were administered a single dose of 60 milligrams (mg) of Zongertinib film-coated tablet orally on Day 1 with 240 milliliters (mL) of water after an overnight fast of at least 10 hours.

DRUGCarbamazepine

Participants received increasing doses of Carbamazepine once daily as extended-release tablets with 240 mL of water for 18 days, starting at 200 mg, then 400 mg, and finally 600 mg. Afterward, they continued taking 600 mg of Carbamazepine once daily for 6 days.

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 55 years (inclusive) * Body mass index (BMI) of 18.5 to 29.9 kg/m2 (inclusive) * Signed and dated written informed consent in accordance with ICH-GCP and local legislation prior to admission to the trial

Exclusion criteria

* Any finding in the medical examination (including BP, PR or ECG, the neurological examination, or the skin inspection) 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 mmHg, or pulse rate outside the range of 50 to 90 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

Participant flow

Recruitment details

The trial was an open-label, two-treatment, two-period, fixed-sequence crossover trial in healthy male Participants comparing the test treatment (T) with the reference treatment (R). Treatment R consisted of one single oral dose of 60 mg zongertinib as a film-coated tablet alone. Treatment T consisted of one single oral dose of 60 mg zongertinib as a film-coated tablet with multiple oral doses of carbamazepine, titrated from 200 mg once daily (q.d.) to 400 mg q.d., then to 600 mg q.d.

Pre-assignment details

A total of 16 participants entered the trial after being screened for eligibility, ensuring they met all inclusion and none of the exclusion criteria. They were allocated to the same treatment sequence to receive 2 treatments in a fixed order (R-T). All 16 received the first treatment (R), and 15 received the second (T). One participant did not start the second treatment due to a positive drug test result but completed the follow-up visit and was not considered to have prematurely discontinued.

Zongertinib Alone: In the reference treatment period, participants were administered a single dose of 60 milligrams (mg) of Zongertinib film-coated tablet orally on Day 1 with 240 milliliters (mL) of water after an overnight fast of at least 10 hours. Zongertinib + Carbamazepine: In the test treatment period (Period 2), participants were administered a single oral dose of 60 milligrams (mg) of Zongertinib in tablet form after an overnight fast of at least 10 hours, with 240 milliliters (mL) of water. This followed 18 days of pretreatment with increasing doses of Carbamazepine, starting at 200 mg, then 400 mg, and finally 600 mg, administered once daily as extended-release tablets with 240 mL of water. Additionally, subjects continued to receive 600 mg of Carbamazepine once daily for 6 days following Zongertinib administration.

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 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.

Time frame: One hour before administration of zongertinib, and at 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 11, 12, 24, 36, 48, 72, 120, and 168 hours after administration.

Population: Pharmacokinetic parameter analysis set (PKS): This set includes all participants in the treated set (TS) who provided at least one PK endpoint that was defined as primary or secondary and was not excluded due to a protocol deviation relevant to the evaluation of PK or due to PK non-evaluability.
