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

Depressive Disorder Clinical Trial

Official title: A Phase 1, Randomized, Double-Blind, Placebo-Controlled, Safety, Tolerability and Pharmacokinetic Study of Escalating Single and Multiple Doses of TAK-653 in Healthy Subjects

Status Completed

Clinical Trial 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.

Clinical Trial 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. ;
