0.03g SRT2104 dosing will take place at approximately the same time every morning after fasting for at least 10 hours. Subjects will be required to stay overnight at the study center for all dosing days. Six subjects are assigned to this cohort. On Day1 of the single dosing period, one subject will be dosed with 0.03g SRT2014 while one is dosed with placebo on Day1. If no safety issues arise from this dosing, then on Day2, three subjects will be dosed with 0.03g SRT2104 while one is dosed with placebo. Subjects within the cohort will remain on a fixed dose for all dosing days. This cohort of subjects will be dosed sequentially approximately two weeks apart from the single dose period, and return to the clinic approximately one week after their single dose administration to receive 7 consecutive days of daily dosing for the multiple dose period. A comprehensive safety assessment will be conducted one week prior to the initiation of an escalated dose in the subsequent cohort.
0.1g SRT2104 dosing will take place at approximately the same time every morning after fasting for at least 10 hours. Subjects will be required to stay overnight at the study center for all dosing days. Six subjects are assigned to this cohort. On Day1 of the single dosing period, one subject will be dosed with 0.1g SRT2014 while one is dosed with placebo on Day1. If no safety issues arise from this dosing, then on Day2, three subjects will be dosed with 0.1g SRT2104 while one is dosed with placebo. Subjects within the cohort will remain on a fixed dose for all dosing days. This cohort of subjects will be dosed sequentially approximately two weeks apart from the single dose period, and return to the clinic approximately one week after their single dose administration to receive 7 consecutive days of daily dosing for the multiple dose period. A comprehensive safety assessment will be conducted one week prior to the initiation of an escalated dose in the subsequent cohort.
0.25g SRT2104 dosing will take place at approximately the same time every morning after fasting for at least 10 hours. Subjects will be required to stay overnight at the study center for all dosing days. Six subjects are assigned to this cohort. On Day1 of the single dosing period, one subject will be dosed with 0.25g SRT2014 while one is dosed with placebo on Day1. If no safety issues arise from this dosing, then on Day2, three subjects will be dosed with 0.25g SRT2104 while one is dosed with placebo. Subjects within the cohort will remain on a fixed dose for all dosing days.
