Phase 1 TAK-906 Single and Multiple Ascending Dose Study in Japanese Healthy Male Participants

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate safety, tolerability, pharmacokinetics, and pharmacodynamics of single and multiple oral doses of TAK-906 in Japanese healthy male participants.

Detailed Description
-----------------
The drug being tested in this study is called TAK-906. TAK-906 is being tested in healthy participants in order to evaluate safety and tolerability of single and multiple oral doses of TAK-906 in Japanese healthy male participants. The study will enroll approximately 24 participants. Participants will be randomly assigned (by chance, like flipping a coin) to one of the two treatment groups in Cohort 1 or Cohort 3. Study drug will be administered in a double-blind manner which will remain undisclosed to the participant and study doctor during the study (unless there is an urgent medical need), orally, once daily on Day 1 as Single Dose Period and twice daily from Day 3 to 7 as Multiple Dose Period: TAK-906 50 mg (Cohort 1) TAK-906 100 mg (Cohort 2) TAK-906 10 mg (Cohort 3) Placebo (dummy inactive pill) - this is a tablet that looks like the study drug but has no active ingredient Cohort 2 will be conducted after the completion of Cohort 1. This will be conducted in Japan.
