Clinical Trial Summary

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.

Description:

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.

Eligibility

Inclusion Criteria:

1. The participant must have a body mass index (BMI) greater than or equal to (>=) 18.5 and less than or equal to (<=) 30.0 kilogram per square meter (kg/m^2) at the screening visit.

2. The participant must be a current nonsmoker at screening as demonstrated by negative cotinine test.

3. The participant has adequate circulation to both hands for safe placement of arterial lines (as determined by Allen's test).

Exclusion Criteria:

1. Has a known hypersensitivity to any component of the formulation of TAK-418 or related compounds, including [18F]MNI-1054.

2. The participant has a positive alcohol or drug screen.

3. The participant has a history of alcohol consumption exceeding 2 standard drinks per day on average (1 glass is approximately equivalent to the following: beer [354 milliliter (mL)/12 ounce (oz)], wine [118 mL/4 oz], or distilled spirits [29.5 mL/1 oz] per day).

4. The participant consumes excessive amounts, defined as greater than 6 servings (1 serving is approximately equivalent to 120 mg of caffeine) of coffee, tea, cola, energy drinks, or other caffeinated beverages per day.

5. The participant has a substance abuse disorder.

6. The participant cannot tolerate venipuncture or has poor venous access that would cause difficulty in collecting blood samples.

7. The participant has contraindications to undergoing magnetic resonance imaging (MRI) examination including but not limited to implants, such as implanted cardiac pacemakers or defibrillators, insulin pumps, cochlear implants, metallic ocular foreign body, implanted neural stimulators, central nervous system aneurysm clips, and other medical implants that have not been certified for MRI, or history of claustrophobia in MRI.

8. The participant has clinically significant abnormal findings on brain MRI scan that in the opinion of the investigator may interfere with the interpretation of the PET imaging.

9. The participant has experienced an acute illness within 10 days before the screening visit.

10. The participant has a risk of suicide according to the investigator's clinical judgement per the Columbia-Suicide Severity Rating Scale at screening or has made a suicide attempt in the 12 months before screening.

11. The participant has luteinizing hormone, follicle stimulating hormone (FSH), or estradiol levels that are clinically abnormal.

12. The participant has existing skin rashes that can be diagnosed as dermatitis.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Quantitative Estimates of Binding of [18F]MNI-1054 Based on PET Radiotracer Kinetic Models At Baseline Scan on Day -1	Enzyme binding parameter [Ki] was obtained from irreversible 2-tissue compartment model (mL/cm^3/min). Data is reported for the following brain regions: cerebellum, frontal lobe, hippocampus, occipital Lobe, pons, and striatum. Here, mL/cm^3/min signifies 'milliliter per cubic centimeter per minute'.	Day -1
Primary	Quantitative Estimates of Binding of [18F]MNI-1054 Based on PET Radiotracer Kinetic Models on Day 1	Enzyme binding parameter [Ki] was obtained from irreversible 2-tissue compartment model (mL/cm^3/min). Data is reported for the following brain regions: cerebellum, frontal lobe, hippocampus, occipital Lobe, pons, and striatum. Here, mL/cm^3/min signifies 'milliliter per cubic centimeter per minute'.	Day 1
Primary	Quantitative Estimates of Binding of [18F]MNI-1054 Based on PET Radiotracer Kinetic Models on Day 2	Enzyme binding parameter [Ki] was obtained from irreversible 2-tissue compartment model (mL/cm^3/min). Data is reported for the following brain regions: cerebellum, frontal lobe, hippocampus, occipital Lobe, pons, and striatum. Here, mL/cm^3/min signifies 'milliliter per cubic centimeter per minute'.	Day 2
Primary	Percent Enzyme Occupancy Based on Quantitative Estimates of Binding for TAK-418 on Day 1	Lysine-Specific Demethylase 1A (LSD1) enzyme occupancy (%) in region of interest (ROI) after a single dose of TAK-418 was obtained from the baseline and postdose Ki values as follows: occupancy (1st postdose) = 100*(Ki [baseline] - Ki [1st postdose]) / Ki (baseline). Data is reported for following brain regions: cerebellum, frontal lobe, hippocampus, occipital Lobe, pons, and striatum.	Day 1
Primary	Percent Enzyme Occupancy Based on Quantitative Estimates of Binding for TAK-418 on Day 2	LSD1 enzyme occupancy (%) in ROI after a single dose of TAK-418 was obtained from the baseline and postdose Ki values as follows: occupancy (2nd postdose) = 100*(Ki [baseline] - Ki [2nd postdose]) / Ki (baseline). Data is reported for following brain regions: cerebellum, frontal lobe, hippocampus, occipital Lobe, pons, and striatum.	Day 2

Secondary	ED50 PET Enzyme Occupancy	The relationship between PET enzyme occupancy and TAK-418 dose level was investigated using an Emax model containing the regression parameters maximal target occupancy (Emax) and dose that gives 50 percent (%) of Emax (ED50). ED50 values are reported for following brain regions: cerebellum, frontal lobe, hippocampus, occipital Lobe, pons, and striatum. The data tabulated are the estimated value and confidence intervals of the ED50 value derived from an Emax model fit across all data points from all arms. ED50 is the dose at which 50% enzyme occupancy is expected.	Days 1 to 2
