The purpose of this 2 part study is to look at how TAK-385 is taken up, broken down and removed from the body when given as a radiolabelled oral solution (by mouth) or as an oral tablet (by mouth) followed by a radiolabelled intravenous (IV) infusion (into the arm vein).
The study will consist of 2 parts involving up to 12 healthy male participants. In Part 1, up to 6 participants will receive a single 80 mg dose of \[14C\]-TAK-385 administered as an oral solution. In Part 2, up to 6 participants will receive a single oral 80 mg dose of TAK-385 administered as two 40 mg tablets and an 80 μg intravenous (into a vein) dose of \[14C\]-TAK-385 (containing not more than 37.0kBq \[1000 nCi\] 14C). This single centre study will take place in the United Kingdom.
