Arm && Interventions

Group	Intervention	Description
Part A - zongertinib (C-14) (T1)	zongertinib (C-14)	Healthy male subjects were administered a single oral dose of radioactively-labelled zongertinib (C-14) as a solution (test treatment 1 \[T1\]) with 240 milliliter (mL) of water, after an overnight fast of at least 10 hours (h). The solution contained a mixture of pure \[14C\]-labelled zongertinib ("hot") drug substance, and zongertinib, i.e. unlabeled ("cold") drug substance, and it contained a radioactive dose of approximately 3.7 Megabecquerel (MBq).
Part B - zongertinib (T2), then zongertinib (C-14) (R)	zongertinib (C-14)	Healthy male subjects were administered one zongertinib film-coated tablet (test treatment 2 \[T2\]) orally with 240 mL of water after an overnight fast of at least 10 h. Two hours later, subjects were administered a single solution of radioactively-labelled zongertinib (C-14) (reference treatment \[R\]) via intravenous infusion. The solution contained a mixture of pure \[14C\]-labelled zongertinib ("hot") drug substance and zongertinib, i.e. unlabelled ("cold") drug substance, and contained a radioactive dose of approximately 0.03 MBq.
Part B - zongertinib (T2), then zongertinib (C-14) (R)	zongertinib	Healthy male subjects were administered one zongertinib film-coated tablet (test treatment 2 \[T2\]) orally with 240 mL of water after an overnight fast of at least 10 h. Two hours later, subjects were administered a single solution of radioactively-labelled zongertinib (C-14) (reference treatment \[R\]) via intravenous infusion. The solution contained a mixture of pure \[14C\]-labelled zongertinib ("hot") drug substance and zongertinib, i.e. unlabelled ("cold") drug substance, and contained a radioactive dose of approximately 0.03 MBq.

Primary Outcome Measures

Name	Time	Method
Part A - Fraction Excreted in Urine and Faeces as Percentage of the Administered Dose Over the Time Interval From 0 to the Last Quantifiable Time Point (fe0-tz)	Urine: within 18 h before and at 0-4, 4-8, 8-12, 12-24, and then at 24 h sampling intervals until 336 h after drug intake. Faeces: within 48 h before, and at 24 h sampling intervals until 336 h after drug intake. Continues in description.	Mass balance and total recovery of \[14C\]-radioactivity: fraction excreted in urine and faeces given as percentage of the administered oral dose of zongertinib (assessed by \[14C\]zongertinib-equivalent\[EQ\]) over the time interval from 0 to the last quantifiable time point (feurine, 0-tz; fefaeces, 0-tz) is reported. Timeframe (continued): after 336 h, if warranted, 24 h collections were to be performed every 7 days on days 21, 28, 35, and 42. Sampling was stopped when the release criteria for radioactivity recovery were met (earliest stopping on Day 15).
Part B - Dose-normalised Area Under the Concentration-time Curve in Plasma Over the Time Interval From 0 Extrapolated to Infinity (AUC0-∞,Norm)	Within 3 h prior and 0.5, 1, 1.5, 2, 2.5, 3, [zongertinib], 2, 2.08, 2.16, 2.25, 2.5, 2.75, 3, 3.5 [[14C]zongertinib], 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120, and 168 h [zongertinib and [14C]zongertinib] after first drug administration.	The dose-normalised area under the concentration-time curve in plasma over the time interval from 0 extrapolated to infinity (AUC0-∞,norm) after oral administration of zongertinib, and after intravenous administration of \[14C\]zongertinib, 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 PK endpoints were log-transformed (natural logarithm) prior to fitting the ANOVA model, which included the effect 'subjects' as a random effect and 'treatment' as a fixed effect. These quantities were then back-transformed to the original scale.
