Mass BalanceScreening period (-48 hours) to 240 hours

Mass balance recovery of total radioactivity in urine and fecal samples.

[14C] CS0159 metaboliteScreening period (-48 hours) to 240 hours

Identification of the major metabolites of CS0159 in human plasma, urine and faeces, determine the main Determine the main biotransformation pathways and calculate the percentage of the administered dose of the prodrug and each metabolite in urine and faeces, and plasma prodrugs and circulating metabolites as a percentage of total exposure AUC.
