研究概览
简要总结
To evaluate the effect of food (low and high fat breakfast vs. fasting) on the pharmacokinetics (what the body does to the drug) of a single dose of solifenacin and tamsulosin administered as combination tablet EC905. Also to evaluate the safety and tolerability of single doses of EC905 in young, healthy male subjects, when administered under fed (low and high fat) or fasting conditions.
详细描述
Subjects are admitted to the clinic on Day -1 and receive a single dose of the combination tablet EC905 on the first day of 3 periods, under three conditions (high fat breakfast, low fat breakfast, and fasting) in order to evaluate the effect of food.
Blood sampling for pharmacokinetic (PK) assessment is performed on the dosing day and for 11 days after dosing in each period. This 11-day on-site period is repeated three times so that all subjects are dosed under all conditions. Each period is separated by 7 days off site.
Subjects return for an End of Study Visit (ESV) at least 7 days after the last 11 day on-site period, or after withdrawal.
On Day 1 of each of 3 periods, subjects are given a single dose of EC905 under three conditions (high fat breakfast, low fat breakfast and fasting) in order to evaluate the effect of food on the PK of solifenacin and tamsulosin HCl. The aim is to show the absence of a food effect after a low fat breakfast vs. fasting conditions, and to evaluate the food effect after a high fat breakfast vs. fasting conditions.
Subjects are randomized to one of 6 possible sequences of fasted or fed conditions.
