This is an open-label, single-dose, single-period, non-randomised study in healthy male subjects. Subjects will be screened for eligibility to participate in the study between 28 and 2 days before dosing. Eligible subjects will be admitted to the clinical unit on the evening of the day before dosing (Day -1). Subjects will be dosed on the morning of Day 1 following an overnight fast of approximately 8 h. Blood, urine, faeces and expired air will be collected at predefined time points for mass balance and PK analysis. Subjects will remain resident in the clinic until the morning of Day 22, when they will be discharged as a group.
