Inclusion criteria

* Male between 18-64 years of age (extremes included) (Part 1) and between 45-64 years of age (extremes included) (Part 2), on the date of signing the informed consent form. * A body mass index (BMI) between 18.0-32.0 kg/m2, inclusive. * Having a regular (at least) daily defecation pattern (i.e. 1 to 3 times per day).

Exclusion criteria

* Radiation exposure, including that from the present study, excluding background radiation but including diagnostic X-rays and other medical exposures, exceeding 5 millisievert (mSv) in the last 12 months or 10 mSv in the last 5 years. Occupationally exposed worker, as defined in the Ionising Radiation Regulations 2017, cannot participate in the study.

Design outcomes

Primary

MeasureTime frameDescription
Absolute oral bioavailability (F) (%)Between Day 1 and Day 22To determine the absolute bioavailability of an oral dose of GLPG1205 relative to an intravenous (i.v.) microtracer dose of \[14C\]-GLPG1205
Recovery of total radioactivity in urine and feces measured as amount of [14C]-GLPG1205 excreted as percentage of the administered dose (Ae%)Between Day 1 and Day 22To assess the mass balance recovery after a single oral dose of \[14C\]-GLPG1205
