Experimental
Arm Label
TAK-935
Arm Description
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.

Outcomes
Primary Outcome Measures
Cholesterol 24S-Hydroxylase (CH24H) Brain Enzyme Occupancy as a Function of TAK-935 Plasma Concentration at 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. The occupancy is determined as the slope of the linear regression of the plot, and the VND as the x-intercept. Data was reported only for TAK-935 600 mg because only first two participants were analyzed at 45 minutes post-TAK-935 dose.
CH24H Brain Enzyme Occupancy as a Function of TAK-935 Plasma Concentration at 2 Hours Post-TAK-935 Dose
CH24H brain enzyme occupancy was obtained by graphical analysis of global occupancy plot.

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 as a Function of TAK-935 Plasma Concentration at 10 Hours Post-TAK-935 Dose

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. Data was reported only for TAK-935 600 mg because only first two participants were analyzed at 10 hour post-TAK-935 dose.

5. Study Description
Brief Summary
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.
Detailed Description
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.
