An Open Label, Single-Dose, Single Period Study Designed to Assess the Mass Balance Recovery, Metabolite Profile and Metabolite Identification of [14C]-A4250 in Healthy Male Subjects

A4250-007

The primary objectives of the study are to assess the mass balance recovery after a single dose of carbon-14 \[14C\]-A4250 as a capsule and to provide plasma, urine and faecal samples for metabolite profiling and structural identification in healthy male subjects.
