Brief summary

For Part 1 of the trial, the main objective is to assess the effect of a single dose of zongertinib on the pharmacokinetics of a single dose of dabigatran-etexilate. For Part 2 of the trial, the main objective is to assess the effect of zongertinib at steady-state on the pharmacokinetics of a single dose of rosuvastatin, metformin and furosemide (administered as a cocktail).

Recruitment details

This was a non-randomised, open-label, 2-period fixed-sequence crossover trial in healthy male participants to compare the test treatments (T: zongertinib and dabigatran-etexilate in part 1; zongertinib, rosuvastatin, metformin, furosemide in part 2) to the reference treatments (R: dabigatran-etexilate in part 1; rosuvastatin, metformin, furosemide in part 2).

Pre-assignment details

All subjects were screened for eligibility prior to participation in the trial. Subjects attended a specialist site which ensured that they (the subjects) strictly met all inclusion and none of the exclusion criteria. Subjects were not included in the trial if any of the entry criteria were violated.

Area under the concentration-time curve of dabigatran in plasma over the time interval from 0 extrapolated to infinity (AUC0-∞) is reported. 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, which included effects accounting for the following sources of variation: participant (considered as random) and treatment (considered as fixed). These quantities were then back-transformed to the original scale.

Time frame: Within 3 hours (h) before dabigatran-etexilate administration (R only), within 3 h prior to zongertinib administration (T only), and 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 7, 8, 10, 12, 24, 34, 48 h after dabigatran-etexilate administration (R and T).

Population: Pharmacokinetic parameter analysis set (PKS) restricted to part 1: all part 1 participants in the 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. Thus, a participant was included in the PKS, even if he contributed only one PK parameter value for one period to the statistical assessment.
