研究概览
简要总结
The purpose of this study is to determine the brain cholesterol 24S-hydroxylase (CH24H) enzyme occupancy of TAK-935 after single oral dose in healthy participants using the positron emission tomography (PET) ligand [18F]MNI-792 and PET imaging and to determine the relationship of occupancy to TAK-935 exposure.
详细描述
The drug being tested in this study is called TAK-935. TAK-935 is being tested to examine the degree and duration of brain CH24H enzyme occupancy/target engagement as a function of TAK-935 plasma concentration in order to guide dosing and schedule for future clinical trials with TAK-935. This study will utilize the PET ligand [18F]MNI-792 to evaluate the brain CH24H occupancy of TAK-935 after single dose oral administration in healthy adult participants. The study will evaluate up to 16 participants. The first 2 participants will take TAK-935 600 mg oral solution and undergo PET imaging using tracer [18F]MNI-792 up to 5 mcg (up to 370 MBq), injection, intravenously prior to each PET scan at Baseline, 45 minutes and 10 hours post-TAK-935 dose. TAK-935 dose and timing of post-dose scans for subsequent participants will be based on the data from the previous participants. This single-center trial will be conducted in the United States. The overall time to participate in this study is up to 55 days. Participants will make 4 visits to the clinic, including 2 confinement periods to the clinic for PET imaging. Participants will be contacted by phone on Day 28 for follow-up safety assessments.

研究组 & 干预措施
TAK-935
A single dose of TAK-935 600 milligram (mg), oral solution on Day 1 as a starting dose and up to 370 megabecquerel (MBq) (10 millicurie [mCi]) of [18F]MNI-792 with a mass of up to 5 microgram (mcg), injection intravenously (IV), prior to each PET imaging at Baseline, 45 minutes and 10 hours post-TAK-935 dose. Subsequent dose of TAK-935 oral solution and timing of PET imaging will be based on safety, tolerability and occupancy data from previous level participants.

结局指标
主要结局
CH24H Brain Enzyme Occupancy as a Function of TAK-935 Plasma Concentration at 2 Hours Post-TAK-935 Dose
时间窗: 2 hours post-TAK-935 dose
CH24H brain enzyme occupancy was obtained by graphical analysis of global occupancy plot. Global occupancy plot was calculated as: VT (Baseline) - VT (Day 1) = Occupancy (Day 1) \* (VT \[Baseline\] - VND), where VT (Baseline) and VT (Day 1) are the total distribution volumes obtained at Baseline and after TAK-935 administration, respectively and VND is the non-displaceable volume of distribution. The occupancy is determined as the slope of the linear regression of the plot, and the VND as the x-intercept.

CH24H brain enzyme occupancy was obtained by graphical analysis of global occupancy plot. Global occupancy plot was calculated as: VT (Baseline) - VT (Day 1) = Occupancy (Day 1) \* (VT \[Baseline\] - VND), where VT (Baseline) and VT (Day 1) are the total distribution volumes obtained at Baseline and after TAK-935 administration, respectively and VND is the non-displaceable volume of distribution.

Cholesterol 24S-Hydroxylase (CH24H) Brain Enzyme Occupancy as a Function of TAK-935 Plasma Concentration at 45 Minutes Post-TAK-935 Dose
时间窗: 45 minutes post-TAK-935 dose
CH24H brain enzyme occupancy was obtained by graphical analysis of global occupancy plot. Global occupancy plot was calculated as: total volume of distribution \[VT\] (Baseline) - VT (Day 1) = Occupancy (Day 1) \* (VT \[Baseline\] - non-displaceable volume of distribution \[VND\]), where VT (Baseline) and VT (Day 1) are the total distribution volumes obtained at Baseline and after TAK-935 administration, respectively and VND is the non-displaceable volume of distribution.
