Study Evaluating The Safety And Tolerability Of Administration Of Single Oral Doses Of SAM-760 To Healthy Subjects
Ascending Single Dose Study Of The Safety, Tolerability And Pharmacokinetics Of SAM-760 Administered Orally To Healthy Young And Healthy Elderly Subjects
This study will assess the safety and tolerability of ascending single oral doses of SAM-760 in healthy young adult and healthy elderly subjects. The secondary objectives are to provide the concentrations of SAM-760 in the blood and to evaluate the effect of a high-fat meal on the concentrations in the blood of SAM-760 administered to healthy young adult subjects, and to evaluate the effects of concomitant administration of ketoconazole on the safety and the concentrations of SAM-760 in the blood of a single dose of SAM-760 in healthy young adult subjects.
