TAK-653 Escalating Single and Multiple Dose Study in Healthy Participants

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess the safety, tolerability and pharmacokinetics (PK) of TAK-653 when administered as single and multiple oral doses at escalating dose levels in healthy participants.

Detailed Description
-----------------
The drug being tested in this study is called TAK-653. TAK-653 is being tested to treat people who have depression. This study will look at the tolerability and PK of TAK-653 in healthy participants. The study may enroll up to 112 participants and each cohort will enroll 8 participants. This study consists of 2 parts: Part 1- single rising dose (SRD) consisting of at least 6 cohorts and Part 2- single rising dose and multiple rising dose (SRD/MRD) consisting of at least 5 cohorts. Additional cohorts may be added depending on the emerging safety and PK data. Participants will be randomly assigned (by chance, like flipping a coin) within each cohort to receive TAK-653 or placebo which will remain undisclosed to the participants and study doctor during the study (unless there is an urgent medical need). Participants enrolled in Cohort 1 to 5 of Part 1 will receive TAK-653 0.3 mg, 1.0 mg, 3.0 mg, 5.0 mg and 9.0 mg or TAK-653 placebo-matching tablet. Subsequent dose escalation in Part-1, from Cohort 6 onward will occur after the full availability of safety, tolerability, PK, and PD data from preceding cohorts. Participants in Part-2 Cohorts 1 to 3 will receive TAK-653 0.3 mg, 1.0 mg and 3.0 mg respectively. Dose for Part 2, from Cohort 4 onward will be based on review of safety, tolerability, and available PK and PD data from previous cohorts. All participants will be asked to take the drug at the same time each day on Day 1 for Part 1 and Day 1 and Days 6 to 18 in Part 2. This single-center trial will be conducted in the United Kingdom. The overall time to participate in this study is approximately 14 days for Part 1 and 31 days for Part 2. Participants will be admitted to the clinic for 6 days in Part 1 and 22 days in Part 2. Participants will be followed up 14 days after last dose of study drug for a follow-up assessment.

Eligibility Criteria
-----------------
Inclusion Criteria: Is capable of understanding and complying with protocol requirements. Signs and dates a written, informed consent form and any required privacy authorization prior to the initiation of any study procedures including requesting that a participant fasts for any laboratory evaluations. Weighs at least 45 kilogram (kg) and has a body mass index (BMI) between 18.0 and 30.0 kilogram per square meter (kg/m^2), inclusive at Screening. Male participant who is nonsterilized and sexually active with a female partner of childbearing potential agrees to use adequate contraception from signing of informed consent throughout the duration of the study and for 90 days after 5 half-lives have elapsed since last dose of study drug. This should be interpreted as 90 days from the Follow-up Call/Visit unless data indicates otherwise. Female participant of childbearing potential who is sexually active with a nonsterilized male partner agrees to routinely use highly effective contraception with low user dependency from signing of informed consent, throughout the duration of the study, and for 30 days after 5 half-lives have elapsed since the last dose of study drug. This should be interpreted as 30 days from the Follow-up Call/Visit unless data indicates otherwise. Exclusion Criteria: Has received any investigational compound within 90 days prior to the first dose of study drug. Is an immediate family member, study site employee, or is in a dependent relationship with a study site employee who is involved in the conduct of this study (example, spouse, parent, child, sibling) or may consent under duress. Has any clinically significant illness, such as cardiovascular, neurologic, pulmonary, hepatic, renal, metabolic, gastrointestinal, urologic, immunologic, endocrine, or psychiatric disease or disorder, or other abnormality, which may affect safety, increase risk of seizure or lower the seizure threshold, or potentially confound the study results. It is the responsibility of the investigator to assess the clinical significance; however, consultation with the Takeda Medical Monitor may be warranted. Has a known hypersensitivity to any component of the formulation of TAK-653. Has taken any excluded medication, supplements, or food products during the time periods. Is pregnant or lactating or intending to become pregnant before, during, or within 30 days after 5 half-lives have elapsed since the last dose of study drug (30 days from the Follow-up Call/Visit unless available data indicates otherwise); or intending to donate ova during such time period. If male, intends to donate sperm during the course of this study or within 90 days after 5 half-lives have elapsed since the last dose of study drug. This should be interpreted as 90 days from the Follow-up Call/Visit unless data indicates otherwise. Has had previous episodes of seizures or convulsion (lifetime), including absence seizure and febrile convulsion. Participant or any immediate family member has a history of epilepsy (including febrile convulsions).
