Last updated: August 25, 2009
Last verified: August 2009
The objective of this study is to investigate how quickly and to what extent the 14-Carbon labeled SAM-531 is absorbed into the bloodstream, converted and eliminated from the body after oral administration in healthy male subjects. As 14-Carbon labeled SAM-531 is radioactive, this enables the compound to be traced in blood, urine and feces.

Condition Intervention Phase
Alzheimer Disease Drug: SAM-531 Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Health Services Research
