GroupInterventionDescription
14C-radiolabelled ACT-13257714C-radiolabeled ACT-132577On Day 1, subjects will receive a single oral dose of 25 mg 14C-radiolabeled ACT-132577, administered as an oral formulation in the fasted state
Primary Outcome Measures
NameTimeMethod
Cumulative excretion of radioactivity in urine and fecesFrom study treatment administration up to day 15

14C-radioactivity will be measured daily in urine and feces samples for determination of total radioactivity recovery

Secondary Outcome Measures
NameTimeMethod
Maximum plasma concentration (Cmax) of 14C-radiolabeled ACT-132577From study treatment administration up to day 15

Cmax is directly derived from the observed plasma concentrations of ACT-132577 and its metabolites

Area under the plasma concentration-time curve (AUC) ACT-132577 and its metabolitesFrom study treatment administration up to day 15

AUC is defined for the time intervals from zero to time t of the last measured concentration above the limit of quantification and from zero to infinity

Terminal half-life (t1/2) of 14C-radiolabeled ACT-132577From study treatment administration up to day 15

t1/2 is calculated from the terminal rate constant obtained from the plasma concentrations-time curves of ACT-132577 and its metabolites

Time to reach Cmax (tmax) of ACT-132577 and its metabolitesFrom study treatment administration up to day 15

tmax is directly derived from the observed plasma concentrations of ACT-132577 and its metabolites

Terminal half-life (t1/2) of ACT-132577 and its metabolitesFrom study treatment administration up to day 15

t1/2 is calculated from the terminal rate constant obtained from the plasma concentrations-time curves of ACT-132577 and its metabolites

Number of subjects with treatment-emergent adverse events and serious adverse eventsFrom study treatment administration up to day 32

Collection of any adverse event at each dose level

Time to reach Cmax (tmax) of 14C-radiolabeled ACT-132577From study treatment administration up to day 15

tmax is directly derived from the observed plasma concentrations of ACT-132577 and its metabolites
