简要总结
The purpose of this study is to determine brain LSD1 enzyme occupancy and the relationship of occupancy to TAK-418 dose and plasma exposure after single oral dosing of TAK-418 in healthy participants using [18F]MNI-1054 positron emission tomography (PET) imaging.
详细描述
The drug being tested in this study is called TAK-418. TAK-418 is being tested to determine the relationship between brain LSD1 enzyme occupancy and TAK-418 plasma concentration. This study will utilize the PET radiotracer [18F]MNI-1054 to evaluate the brain LSD1 enzyme occupancy of TAK-418 after single dose oral administration in healthy adult participants.
The study will enroll approximately 16 participants. The TAK-418 starting dose is 1.5 mg, given on Day 1. Each participant will receive one dose of TAK-418 and up to 3 dynamic [18F]MNI-1054 PET scans to assess enzyme occupancy on baseline, Day 1 and Day 2 or 3 post-TAK-418 dosing.
This single center trial will be conducted in the United States. The overall time to participate in this study is 62 days. Participants will be followed up on Day 14 for follow-up safety assessments.

研究组 & 干预措施
TAK-418 1.5 mg
TAK-418 1.5 milligram (mg), orally, once on Day 1. Participants will also receive 10 millicurie (mCi) of [18F]MNI-1054 injection intravenously, prior to each PET scans on Day -1, Day 1, and either on Day 2 or 3. Dose levels for subsequent participants may vary based on available review of imaging and pharmacokinetics (PK) data.
