Part A - the primary objective is to assess the mass balance and total recovery of \[14C\]-radioactivity in urine and faeces after oral single dose administration of BI 1810631 (C-14) (test treatment T1) in healthy male subjects. Part A - the secondary objective is to assess concentrations of BI 1810631 and \[14C\]-radioactivity in plasma. Part B - the primary objective is to investigate the absolute bioavailability of BI 1810631 administered as film-coated tablet (test treatment T2, not radio-labelled) compared with BI 1810631 (C-14) (reference treatment R) administered as intravenous microtracer.

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)
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).
Time frame: Within 18 h (urine) or 48 h (faeces) before drug intake; at 0-4, 4-8, 8-12, 12-24 (urine); and at 24 h sampling intervals until 336 h after drug intake (both). Both: after 336 h, every 7 days, up to day 42. Continues in description.
Part B - Dose-normalised Area Under the Concentration-time Curve in Plasma Over the Time Interval From 0 Extrapolated to Infinity (AUC0-∞,Norm)
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.
Time frame: 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.
Part A - Maximum Measured Concentration of Zongertinib in Plasma (Cmax)
Maximum measured concentration of zongertinib in plasma (Cmax) is reported.
Time frame: Within 3 h prior and 0.5, 1, 1.5, 2, 2.5, 3, 4, 5, 6, 8, 10, 12, 24, 36, 48, 72, 96, 120, 168, 216, 264, 336 h after drug administration.
