Radiocarbon will be assayed in all available samples (whole blood, plasma, urine, feces, and expired air) by liquid scintillation spectrometry. The metabolic profile of GFT505 will be assayed in plasma, urine, and feces. Non-radioactive pharmacokinetics of GFT505 and its principle metabolite GFT1007 will be assayed in plasma and urine. Other metabolites will be investigated in plasma and urine according to the radioactivity results. Non-radioactive pharmacokinetics of GFT505 and metabolites in feces will be investigated according to the radioactivity results.
