a study to determine the metabolism and elimination of [14c]e2027 in healthy male participants

Conditions: Dementias With Lewy Bodies

Summary: the primary objective of the study is to achieve mass balance recovery of \[14c\]-radiolabel in urine and feces and to identify and quantify the main elimination pathways of e2027.
